"Industrial stormwater" means stormwater runoff associated
with the definition of "stormwater discharge associated with from
industrial activity."
"Land application unit" means an area where wastes are applied onto or incorporated into the soil surface (excluding manure spreading operations) for treatment or disposal.
"Landfill" means an area of land or an excavation in which wastes are placed for permanent disposal, and that is not a land application unit, surface impoundment, injection well, or waste pile.

activities are protected by a storm-resistant shelter to prevent exposure to
rain, snow, snowmelt, and/or or runoff.
"Primary industrial activity" includes any activities performed on-site which are:
1. Identified by the facility's primary SIC code; or
2. Included in the narrative descriptions of the definition of "industrial activity."
Narrative descriptions in the "industrial activity" definition include: category 1 activities subject to stormwater effluent limitations guidelines, new source performance standards, or toxic pollutant effluent standards; category 4 hazardous waste treatment storage or disposal facilities, including those that are operating under interim status or a permit under subtitle C of the Resource Conservation and Recovery Act RCRA; category 5 landfills, land application sites, and open dumps that receive or have received industrial wastes; category 7 steam electric power generating facilities; and category 9 sewage treatment works with a design flow of 1.0 mgd or more.
For colocated activities covered by multiple SIC codes, the primary industrial determination should be based on the value of receipts or revenues, or, if such information is not available for a particular facility, the number of employees or production rate for each process may be compared. The operation that generates the most revenue or employs the most personnel is the operation in which the facility is primarily engaged. In situations where the vast majority of on-site activity falls within one SIC code, that activity may be the primary industrial activity.

The term excludes areas located on plant lands separate from the plant's industrial activities, such as office buildings and accompanying parking lots, as long as the drainage from the excluded areas is not mixed with stormwater drained from the above described areas. Industrial facilities include those that are federally, state, or municipally owned or operated that meet the description of the facilities listed in the "industrial activity" definition. The term also includes those facilities designated under the provisions of 9VAC25-31-120 A 1 c, or under 9VAC25-31-120 A 7 a (1) or (2) of the VPDES Permit Regulation.
"Total maximum daily load" or "TMDL" means a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL includes wasteload allocations (WLAs) for point source discharges, load allocations (LAs) for nonpoint sources and/or natural background, and must include a margin of safety (MOS) and account for seasonal variations.
"Virginia Environmental Excellence Program" or "VEEP" means a voluntary program established by the department to provide public recognition and regulatory incentives to encourage higher levels of environmental performance for program participants that develop and implement environmental management systems (EMSs).

These sector descriptions are based on Standard Industrial Classification (SIC) Codes and Industrial Activity Codes. References to "sectors" in this permit (e.g., sector-specific monitoring requirements) refer to these groupings.
B. Limitations on coverage.
1. The owner shall not be authorized to discharge under this
general permit if the owner has been required to obtain an individual permit
pursuant to 9VAC25-31-170 B;
2. The owner shall not be authorized by this general permit
to discharge to state waters specifically named in other board regulations or
policies which prohibit such discharges;
3. The following stormwater discharges associated with
industrial activity are not authorized by this permit:
a. Discharges that are located at a facility where a VPDES
permit has been terminated (other than at the request of the permittee) or
denied;
b. Discharges that the director determines cause, or may
reasonably be expected to cause, or be contributing to a violation of a water
quality standard;
c. Discharges subject to effluent limitation guidelines,
not described under 9VAC25-151-70, Table 70-2;
d. Discharges to waters for which a "total maximum
daily load" (TMDL) allocation has been established by the board and
approved by EPA prior to the term of this permit, unless the owner develops,
implements, and maintains a stormwater pollution prevention plan (SWPPP) that
is consistent with the assumptions and requirements of the TMDL. This only
applies where the facility is a source of the TMDL pollutant of concern. The
SWPPP shall specifically address any conditions or requirements included in the
TMDL that are applicable to discharges from the facility. If the TMDL establishes
a specific numeric wasteload allocation that applies to discharges from the
facility, the owner shall implement BMPs designed to meet that allocation;
e. New dischargers that discharge to impaired waters for
which a TMDL has not been established by the board and approved by EPA unless:
(1) The discharger prevents all exposure to stormwater of
the pollutant(s) for which the waterbody is impaired, and retains documentation
of the procedures taken to prevent exposure onsite with the SWPPP required by
9VAC25-151-70;
(2) The discharger documents that the pollutant(s) for
which the waterbody is impaired is not present at the site, and retains
documentation of this finding with the SWPPP required by 9VAC25-151-70; or
(3) Prior to submitting a registration statement, the
discharger provides to the appropriate DEQ regional office data to support a
showing that the discharge is not expected to cause or contribute to an
exceedance of a water quality standard. The discharger shall provide data and
other technical information to the regional office sufficient to demonstrate
that the discharge of the pollutant for which the water is impaired will meet
in-stream water quality criteria at the point of discharge to the waterbody.
The discharges from the facility are authorized under this permit if the
discharger receives an affirmative determination from the regional office that
the discharges will not contribute to the existing impairment. The discharger
shall maintain the supporting data and the regional office determination onsite
with the SWPPP required by 9VAC25-151-70; and
f. Discharges that do not comply with Virginia's
antidegradation policy for water quality standards under 9VAC25-260-30. If
authorization to discharge under this general permit will not comply with the
antidegradation requirements, an individual permit application may be required
to allow a discharge that meets the requirements for high quality waters in
9VAC25-260-30 A 2, or permits may be denied to meet the requirements for
exceptional waters in 9VAC25-260-30 A 3.
4. Facilities covered. Permit eligibility is limited to
discharges from facilities in the "sectors" of industrial activity
based on Standard Industrial Classification (SIC) codes and Industrial Activity
codes summarized in Table 50‑1. References to "sectors" in this
permit refer to these sectors.

C. D. Conditional exclusion for no exposure. If
an Any owner is covered by this permit, but later is able
to file a no exposure certification to be excluded who becomes eligible
for a no exposure exclusion from permitting under 9VAC25-31-120 E, the
owner is no longer authorized by nor required to comply with this permit. If
the owner is no longer required to have permit coverage due to a no exposure
exclusion, may file a no exposure certification. Upon submission and
acceptance by the board of a complete and accurate no exposure certification,
the permit requirements no longer apply, and the owner is not required to
submit a notice of termination. A no exposure certification must be
submitted to the board once every five years.
D. Receipt of E. Compliance with this general permit
constitutes compliance with the federal Clean Water Act and the State Water
Control Law, with the exceptions stated in 9VAC25-31-60 of the VPDES Permit
Regulation. Approval for coverage under this general permit does not
relieve any owner of the responsibility to comply with any other applicable
federal, state, or local statute, ordinance, or regulation.
F. Continuation of permit coverage.
1. Any owner that was authorized to discharge under the
industrial activity stormwater general permit issued in 2009 and that submits a
complete registration statement [ on or ] before
July 1, 2014, is authorized to continue to discharge under the terms of the
2009 general permit until such time as the board either:
a. Issues coverage to the owner under this general permit; or
b. Notifies the owner that the discharge is not eligible for coverage under this general permit.
2. When the owner that was covered under the expiring or expired general permit has violated or is violating the conditions of that permit, the board may choose to do any or all of the following:
a. Initiate enforcement action based upon the 2009 general permit;
b. Issue a notice of intent to deny coverage under the reissued general permit. If the general permit coverage is denied, the owner would then be required to cease the discharges authorized by administratively continued coverage under the terms of the 2009 general permit or be subject to enforcement action for discharging without a permit;
c. Issue an individual permit with appropriate conditions; or
d. Take other actions authorized by the VPDES Permit Regulation (9VAC25-31).

General Permit No.: VAR05
Effective Date: July 1, 2009 2014
Expiration Date: June 30, 2014 2019
GENERAL PERMIT FOR STORMWATER DISCHARGES ASSOCIATED WITH INDUSTRIAL
ACTIVITY
AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA POLLUTANT DISCHARGE ELIMINATION
SYSTEM AND THE VIRGINIA STATE WATER CONTROL LAW
In compliance with the provisions of the Clean Water Act, as
amended, and pursuant to the State Water Control Law and regulations adopted
pursuant thereto, owners of facilities with stormwater discharges associated
with industrial activity are authorized to discharge to surface waters within
the boundaries of the Commonwealth of Virginia, except those waters
specifically named in board regulation or policies which that
prohibit such discharges.
The authorized discharge shall be in accordance with this cover page, Part I-Effluent Limitations, Monitoring Requirements and Special Conditions, Part II-Conditions Applicable to All VPDES Permits, Part III-Stormwater Pollution Prevention Plan, and Part IV-Sector-Specific Permit Requirements, as set forth herein.
Part I
Effluent Limitations, Monitoring Requirements and Special Conditions
A. Effluent limitations and monitoring requirements.
There are three four individual and separate
categories of monitoring requirements that a facility may be subject to under
this permit: (i) quarterly visual monitoring; (ii) benchmark monitoring of
discharges associated with specific industrial activities; and (iii)
compliance monitoring for discharges subject to numerical effluent limitations;
and (iv) monitoring of discharges to impaired waters, both those with an
approved TMDL and those without an approved TMDL. The monitoring
requirements and numeric effluent limitations applicable to a facility depend
on the types of industrial activities generating stormwater runoff from the
facility, and for TMDL monitoring, the location of the facility facility's
discharge or discharges. Part IV of the permit (9VAC25-151-90 et seq.)
identifies monitoring requirements applicable to specific sectors of industrial
activity. The permittee shall review Part I A 1 and Part IV of the permit to
determine which monitoring requirements and numeric limitations apply to his facility.
Unless otherwise specified, limitations and monitoring requirements under Part
I A 1 and Part IV are additive.
Sector-specific monitoring requirements and limitations are
applied discharge by discharge at facilities with colocated activities. Where stormwater
from the colocated activities are commingled, the monitoring requirements and
limitations are additive. Where more than one numeric limitation for a specific
parameter applies to a discharge, compliance with the more restrictive
limitation is required. Where monitoring requirements for a monitoring period
overlap (e.g., need to monitor TSS one/year twice per year for a
limit and also one/year twice per year for benchmark monitoring),
the permittee may use a single sample to satisfy both monitoring requirements.
1. Types of monitoring requirements and limitations.
a. Quarterly visual monitoring. The requirements and procedures for quarterly visual monitoring are applicable to all facilities covered under this permit, regardless of the facility's sector of industrial activity.
(1) The permittee shall perform and document a quarterly
visual examination of a stormwater discharge associated with industrial
activity from each outfall, except discharges exempted below (Part I A 1 a
(2) and (4), and Part I A 3) in Part I A 3 or Part I A 4. The
examination(s) shall be made at least once in each of the following three-month
periods: January through March, April through June, July through September, and
October through December. The visual examination shall be made during daylight
hours (e.g., normal working hours) normal working hours, where
practicable, and when considerations for safety and feasibility allow. If
no storm event resulted in runoff from the facility during a monitoring
quarter, the permittee is excused from visual monitoring for that quarter
provided that documentation is included with the monitoring records indicating
that no runoff occurred. The documentation shall be signed and certified in
accordance with Part II K of this permit.
(2) Visual examinations shall be made of samples collected
within the first 30 minutes (or as soon thereafter as practical, but not to
exceed one hour) of when the runoff or snowmelt begins discharging from the
facility. Samples shall be collected in accordance with Part I A 2.
The examination shall document observations of color, odor, clarity, floating
solids, settled solids, suspended solids, foam, oil sheen, and other obvious
indicators of stormwater pollution. The examination shall be conducted in a
well-lit area. No analytical tests are required to be performed on the samples.
All samples (except snowmelt samples) shall be collected from the discharge
resulting from a storm event that results in an actual discharge from the site
(defined as a "measurable storm event"), and that occurs at least 72
hours from the previously measurable storm event. The 72-hour storm interval is
waived if the permittee is able to document that less than a 72-hour interval
is representative for local storm events during the sampling period.
[ Where practicable, the same individual shall carry out the collection
and examination of discharges for the entire permit term. ] If no
qualifying storm event resulted in runoff during daylight hours from the
facility during a monitoring quarter, the permittee is excused from visual
monitoring for that quarter provided that documentation is included with the
monitoring records indicating that no qualifying storm event occurred during
daylight hours that resulted in stormwater runoff during that quarter. The
documentation shall be signed and certified in accordance with Part II K.
(3) The visual examination reports shall be maintained on-site with the Stormwater Pollution Prevention Plan (SWPPP). The report shall include the outfall location, the examination date and time, examination personnel, the nature of the discharge (i.e., runoff or snow melt), visual quality of the stormwater discharge (including observations of color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of stormwater pollution), and probable sources of any observed stormwater contamination.
(4) Inactive and unstaffed sites: When the permittee is
unable to conduct visual stormwater examinations at an inactive and unstaffed
site, a waiver of the monitoring requirement may be exercised as long as the
facility remains inactive and unstaffed, and there are no industrial materials
or activities exposed to stormwater. If this waiver is exercised, the permittee
shall maintain a certification with the SWPPP stating that the site is inactive
and unstaffed, there are no industrial materials or activities exposed to stormwater,
and that performing visual examinations during a qualifying event is not
feasible. The waiver shall be signed and certified in accordance with Part II
K.
(5) Representative outfalls - essentially identical
discharges. If the facility has two or more outfalls that discharge
substantially identical effluents, based on similarities of the industrial
activities, significant materials, size of drainage areas, and stormwater
management practices occurring within the drainage areas of the outfalls, the
permittee may conduct visual monitoring on the effluent of just one of the
outfalls and report that the observations also apply to the substantially
identical outfall(s). The permittee shall include the following information in
the SWPPP:
(a) The locations of the outfalls;
(b) Why the outfalls are expected to discharge
substantially identical effluents, including evaluation of monitoring data,
where available;
(c) Estimates of the size of the drainage area (in square
feet) for each of the outfalls; and
(d) An estimate of the runoff coefficient of the drainage
areas (low: under 40%; medium: 40% to 65%; high: above 65%).
(6) If a facility's permit coverage is effective less than
one month from the end of a quarterly monitoring period, the first quarterly
period starts with the next respective quarterly monitoring period (e.g., if
permit coverage begins March 5, the permittee will not need to start quarterly
visual monitoring until the April-June quarter).
b. Benchmark monitoring of discharges associated with specific industrial activities.
Table 70-1 identifies the specific industrial sectors subject to the benchmark monitoring requirements of this permit and the industry-specific pollutants of concern. The permittee shall refer to the tables found in the individual sectors in Part IV (9VAC25-151-90 et seq.) for benchmark monitoring concentration values. Colocated industrial activities at the facility that are described in more than one sector in Part IV shall comply with all applicable benchmark monitoring requirements from each sector.
The results of benchmark monitoring are primarily for the permittee to use to determine the overall effectiveness of the SWPPP in controlling the discharge of pollutants to receiving waters. Benchmark concentration values, included in Part IV of this permit, are not effluent limitations. Exceedance of a benchmark concentration does not constitute a violation of this permit and does not indicate that violation of a water quality standard has occurred; however, it does signal that modifications to the SWPPP are necessary, unless justification is provided in the comprehensive site compliance evaluation (Part III E). In addition, exceedance of benchmark concentrations may identify facilities that would be more appropriately covered under an individual, or alternative general permit where more specific pollution prevention controls could be required.

|
(1) (a) If a facility falls within a sector(s) required to
conduct benchmark monitoring, monitoring Benchmark monitoring shall be
performed for all benchmark parameters specified for the industrial sector or
sectors applicable to a facility's discharge. Monitoring shall be performed
at least once during each of the first two four, and potentially
all, monitoring periods after the facility is granted coverage under the
permit begins. Monitoring commences with the first full monitoring
period after the owner is granted coverage under the permit. Monitoring periods
are specified in Part I A 2.
Depending on the results of two four consecutive
monitoring periods, benchmark monitoring may not be required to be conducted in
subsequent monitoring periods (see Part I A 1 b (2)) (see subdivision
(2) below).
(b) Monitoring periods for benchmark monitoring. The benchmark
monitoring periods are as follows: (i) July 1, 2009, to December 31, 2009; (ii)
January 1, 2010, to December 31, 2010; (iii) January 1, 2011, to December 31,
2011; (iv) January 1, 2012, to December 31, 2012; and, (v) January 1, 2013, to
December 31, 2013.
(c) If a facility's permit coverage is effective less than
one month from the end of a monitoring period, the facility's first monitoring
period starts with the next respective monitoring period (e.g., if permit
coverage begins December 5, the permittee will not need to start sampling until
the next January-December monitoring period).
(2) Benchmark monitoring waivers for facilities testing below benchmark concentration values. Waivers from benchmark monitoring are available to facilities whose discharges are below benchmark concentration values on an outfall by outfall basis. Sector-specific benchmark monitoring is not required to be conducted in subsequent monitoring periods during the term of this permit provided:
(a) Samples were collected in two four
consecutive monitoring periods, and all the parameter concentrations
were average of the four samples for all parameters at the outfall is
below the applicable benchmark concentration values value in Part
IV. (Note: facilities that were covered under the 2009 industrial stormwater
general permit may use sampling data from the last two monitoring periods of
that permit and the first two monitoring periods of this permit to satisfy the
four consecutive monitoring periods requirement); and
(b) The facility is not subject to a numeric effluent
limitation for that parameter established in Part I A 1 c (1) (Stormwater
Effluent Limitations, Coal Pile Runoff, and TMDL Wasteload Allocations) (Stormwater
Effluent Limitations), Part I A 1 c (2) (Coal Pile Runoff), or Part IV
(Sector Specific Permit Requirements) for any of the parameters at that
outfall; and
(c) A waiver request is submitted to and approved by the department
board. The waiver request shall be sent to the appropriate DEQ
regional office, along with the supporting monitoring data for two four
consecutive monitoring periods, and a certification that, based on current
potential pollutant sources and [ BMPs control measures ]
used, discharges from the facility are reasonably expected to be essentially
the same (or cleaner) compared to when the benchmark monitoring for the two
four consecutive monitoring periods was done.
Waiver requests will be evaluated by the department board
based upon: (i) benchmark monitoring results below the benchmark concentration
values; (ii) a favorable compliance history (including inspection results); and
(iii) no outstanding enforcement actions.
The monitoring waiver may be revoked by the department board
for just cause. The permittee will be notified in writing that the monitoring
waiver is revoked, and that the benchmark monitoring requirements are again in
force and will remain in effect until the permit's expiration date.
(3) Samples shall be collected and analyzed in accordance with
Part I A 2. For each outfall, one signed Discharge Monitoring Report (DMR)
form shall be submitted to the department for each storm event sampled.
Monitoring results shall be Monitoring results shall be reported in accordance
with Part I A 5 and Part II C and retained in accordance with Part II B.
(4) Inactive and unstaffed sites. If the permittee is
unable to conduct benchmark monitoring at an inactive and unstaffed site, a
waiver of the monitoring requirement may be exercised as long as the facility
remains inactive and unstaffed, and there are no industrial materials or
activities exposed to stormwater. If the permittee exercises this waiver, a
certification shall be submitted to the department and maintained with the
SWPPP stating that the site is inactive and unstaffed, there are no industrial
materials or activities exposed to stormwater, and that performing benchmark
monitoring during a qualifying storm event is not feasible. The waiver shall be
signed and certified in accordance with Part II K.
(5) Representative outfalls - essentially identical
discharges. If the facility has two or more outfalls that discharge
substantially identical effluents, based on similarities of the industrial
activities, significant materials, size of drainage areas, and stormwater
management practices occurring within the drainage areas of the outfalls, the
permittee may perform benchmark monitoring on the effluent of just one of the
outfalls and report that the quantitative data also applies to the
substantially identical outfall(s). The permittee shall include the following
information in the SWPPP, and in any DMRs that are required to be submitted to
the department:
(a) The locations of the outfalls;
(b) Why the outfalls are expected to discharge
substantially identical effluents, including evaluation of monitoring data,
where available;
(c) Estimates of the size of the drainage area (in square
feet) for each of the outfalls; and
(d) An estimate of the runoff coefficient of the drainage
areas (low: under 40%; medium: 40% to 65%; high: above 65%).
c. Compliance monitoring for discharges subject to numerical effluent limitations or discharges to impaired waters.
(1) Facilities subject to stormwater effluent limitation guidelines.
(a) Facilities subject to stormwater effluent limitation
guidelines (see Table 70-2) are required to monitor such discharges to evaluate
compliance with numerical effluent limitations. Industry-specific numerical
limitations and compliance monitoring requirements are described in Part IV of
the permit (9VAC25-151-90 et seq.). Colocated Permittees with
colocated industrial activities at the facility that are described in more
than one sector in Part IV shall comply on a discharge-by-discharge basis with all
applicable effluent limitations from each sector.
(b) Permittees shall monitor the discharges for the presence
of the pollutant subject to the effluent limitation at least once during each
of the monitoring periods after the facility is granted coverage under
the permit begins. If a facility's permit coverage is effective less
than one month from the end of a monitoring period, the facility's first
monitoring period starts with the next respective monitoring period (e.g., if
permit coverage begins December 5, the permittee will not need to start the
effluent limitation monitoring until the next January-December monitoring
period). Monitoring commences with the first full monitoring period
after the owner is granted coverage under the permit. Monitoring periods are
specified in Part I A 2. The substantially identical outfall monitoring
provisions (Part I A 2 f) are not available for numeric effluent limits
monitoring.
(c) The monitoring periods for effluent limitation
monitoring are as follows: (i) July 1, 2009, to December 31, 2009; (ii) January
1, 2010, to December 31, 2010; (iii) January 1, 2011, to December 31, 2011;
(iv) January 1, 2012, to December 31, 2012; and (v) January 1, 2013, to
December 31, 2013.
(d) (c) Samples shall be collected and analyzed
in accordance with Part I A 2. Monitoring results shall be reported in
accordance with Part I A 4 5 and Part II C, and retained in
accordance with Part II B.

(2) Facilities subject to coal pile runoff monitoring.
(a) Facilities with discharges of stormwater from coal storage piles shall comply with the limitations and monitoring requirements of Table 70-3 for all discharges containing the coal pile runoff, regardless of the facility's sector of industrial activity.
(b) Permittees shall monitor such stormwater discharges at
least once during each of the monitoring periods after the facility is
granted coverage under the permit begins. If a facility's permit
coverage is effective less than one month from the end of a monitoring period,
the facility's first monitoring period starts with the next respective
monitoring period (e.g., if permit coverage begins December 5, the permittee
will not need to start the coal pile runoff monitoring until the next
January-December monitoring period). Monitoring commences with the first
full monitoring period after the owner is granted coverage under the permit.
Monitoring periods are specified in Part I A 2. The substantially identical
outfall monitoring provisions (Part I A 2 f) are not available for coal pile
numeric effluent limits monitoring.
(c) Coal pile runoff monitoring periods are as follows: (i)
July 1, 2009, to December 31, 2009; (ii) January 1, 2010, to December 31, 2010;
(iii) January 1, 2011, to December 31, 2011; (iv) January 1, 2012, to December
31, 2012; and (v) January 1, 2013, to December 31, 2013.
(d) (c) The coal pile runoff shall not be
diluted with other stormwater or other flows in order to meet this limitation.
(e) (d) If a facility is designed, constructed
and operated to treat the volume of coal pile runoff that is associated with a
10-year, 24-hour rainfall event, any untreated overflow of coal pile runoff
from the treatment unit is not subject to the 50 mg/L limitation for total
suspended solids.
(f) (e) Samples shall be collected and analyzed
in accordance with Part I A 2. Monitoring results shall be reported in
accordance with Part I A 4 5 and Part II C, and retained in
accordance with Part II B.

(3) Facilities (discharging discharging to an
impaired water with a board-established and EPA-approved an approved
TMDL wasteload allocation.
[ Owners of facilities that are a source of the specified pollutant of concern to waters for which a TMDL wasteload allocation has been approved prior to the term of this permit will be notified as such by the department when they are approved for coverage under the general permit. ]
(a) Upon written notification from the department, facilities subject to TMDL wasteload allocations will be required to monitor such discharges to evaluate compliance with the TMDL requirements.
(b) Permittees shall monitor the discharges for the pollutant
subject to the TMDL wasteload allocation at least semiannually (twice per
year) once during each of the monitoring periods after coverage under
the permit begins. The TMDL semiannual monitoring periods are from July
1 to December 31, and January 1 to June 30. If a facility's notification that
they are subject to the TMDL monitoring requirements is effective less than one
month from the end of a semiannual monitoring period, the facility's first monitoring
period starts with the next respective monitoring period (e.g., if notification
is given on December 5, the permittee will not need to start semiannual
monitoring until the next January 1 to June 30 monitoring period). Monitoring
commences with the first full monitoring period after the owner is granted
coverage under the permit. Monitoring periods are specified in Part I A 2.
[ Note: Facilities discharging to waters impaired
for PCBs shall follow the monitoring schedule and the pollutant minimization
plan (PMP) requirements described in the written notification from the
department. ]
(c) Samples shall be collected and analyzed in accordance with
Part I A 2. Monitoring results shall be reported in accordance with Part I A 4
5 and Part II C, and retained in accordance with Part II B.
(d) If the pollutant subject to the TMDL wasteload allocation
is [ not detected in any below the quantitation level in all ]
of the samples from the first four monitoring periods (i.e., the first two
years of coverage under the permit), the permittee may request to the department
board in writing that further sampling be discontinued, unless the TMDL
has specific instructions to the contrary (in which case those instructions
shall be followed). The laboratory certificate of analysis shall be
submitted with the request. If approved, documentation of this shall be
kept with the SWPPP.
If the pollutant subject to the TMDL wasteload allocation is
[ detected above the quantitation level ] in any of the
samples from the first four monitoring periods, the permittee shall continue
the scheduled TMDL monitoring throughout the term of the permit.
(4) Facilities discharging to an impaired water without a
board established and EPA-approved an approved TMDL wasteload
allocation.
[ Owners of facilities that discharge to waters listed as impaired in the 2012 Final 305(b)/303(d) Water Quality Assessment Integrated Report, and for which a TMDL wasteload allocation has not been approved prior to the term of this permit, will be notified as such by the department when they are approved for coverage under the general permit. ]
(a) Upon written notification from the department, facilities
discharging to an impaired water without a board established and
EPA-approved an approved TMDL wasteload allocation will be required
to monitor such discharges for the pollutant(s) that caused the impairment.
(b) Permittees shall monitor the discharges for all pollutants
for which the waterbody is impaired, and for which a standard analytical method
exists, at least once during each of the monitoring periods after the
facility is granted coverage under the permit begins. If a
facility's permit coverage is effective less than one month from the end of a
monitoring period, the facility's first monitoring period starts with the next
respective monitoring period (e.g., if permit coverage begins December 5, the
permittee will not need to start the impaired water monitoring until the next
January-December monitoring period). Monitoring commences with the first
full monitoring period after the owner is granted coverage under the permit.
Monitoring periods are specified in Part I A 2.
[ Note: Facilities discharging to waters impaired
for PCBs shall follow the monitoring schedule and the pollutant minimization
plan (PMP) requirements described in the written notification from the
department. ]
(c) The impaired water monitoring periods are as follows:
(i) July 1, 2009, to December 31, 2009; (ii) January 1, 2010, to December 31,
2010; (iii) January 1, 2011, to December 31, 2011; (iv) January 1, 2012, to
December 31, 2012; and (v) January 1, 2013, to December 31, 2013.
(d) (c) If the pollutant for which the waterbody
is impaired is suspended solids, turbidity or sediment/sedimentation,
or sediment, or sedimentation, monitor for Total Suspended Solids total
suspended solids (TSS). If the pollutant for which the waterbody is
impaired is expressed in the form of an indicator or surrogate pollutant,
monitor for that indicator or surrogate pollutant. No monitoring is required when
a waterbody's biological communities are impaired but no pollutant, including
indicator or surrogate pollutants, is specified as causing the impairment, or
when a waterbody's impairment is related to hydrologic modifications, impaired
hydrology, or temperature.
Samples shall be collected and analyzed in accordance with
Part I A 2. Monitoring results shall be reported in accordance with Part I A 4
5 and Part II C, and retained in accordance with Part II B.
(e) (d) If the pollutant for which the water is
impaired is [ not present below the quantitation level ]
in the discharges from the facility, or it is [ present above
the quantitation level ] but its presence is caused solely by natural
background sources, a notification to this effect shall be included in the
first discharge monitoring report submitted by the facility, after which
the permittee may request to the board in writing that further impaired
water monitoring may be discontinued. The laboratory certificate of
analysis shall be submitted with the request. If approved, documentation of
this shall be kept with the SWPPP.
To support a determination that the pollutant's presence is caused solely by natural background sources, the following documentation shall be submitted with the request and kept with the SWPPP: (i) an explanation of why it is believed that the presence of the impairment pollutant in the facility's discharge is not related to the activities at the facility; and (ii) data or studies that tie the presence of the impairment pollutant in the facility's discharge to natural background sources in the watershed. Natural background pollutants include those substances that are naturally occurring in soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity at the facility's site, or pollutants in run-on from neighboring sources that are not naturally occurring.
2. Monitoring instructions.
a. Collection and analysis of samples. Sampling requirements shall be assessed on an outfall by outfall basis. Samples shall be collected and analyzed in accordance with the requirements of Part II A.
b. When and how to sample. A minimum of one grab sample shall
be taken from the discharge associated with industrial activity resulting from
a storm event that results in an actual discharge from the site (defined as a
"measurable storm event"), providing the interval from the preceding
measurable storm event is at least 72 hours. The 72-hour storm interval is
waived if the permittee is able to document that less than a 72-hour interval
is representative for local storm events during the sampling period. In the
case of snowmelt, the monitoring must shall be performed at a
time when a measurable discharge occurs at the site. For discharges from a stormwater
management structure, the monitoring shall be performed at a time when a
measurable discharge occurs from the structure.
The grab sample shall be taken during the first 30 minutes of
the discharge. If it is not practicable to take the sample during the first 30 minutes,
the sample may be taken during the first hour three hours of the
discharge, provided that the permittee explains why a grab sample during
the first 30 minutes was impracticable. This information shall be submitted on
or with the Discharge Monitoring Report (DMR), or and maintained
with the SWPPP if reports are not required to be submitted. If the
sampled discharge commingles with process or nonprocess water, the permittee
shall attempt to sample the stormwater discharge before it mixes with the nonstormwater.
c. Storm event data. For each monitoring event (except snowmelt monitoring), along with the monitoring results, the permittee shall identify the date and duration (in hours) of the storm event(s) sampled; rainfall total (in inches) of the storm event that generated the sampled runoff; and the duration between the storm event sampled and the end of the previous measurable storm event. For snowmelt monitoring, the permittee shall identify the date of the sampling event.
d. Monitoring periods.
(1) Quarterly visual monitoring. The quarterly visual examinations shall be made at least once in each of the following three-month periods each year of permit coverage: January through March, April through June, July through September, and October through December.
(2) Benchmark monitoring, effluent limitation monitoring, and impaired waters monitoring (for waters both with and without an approved TMDL). Monitoring shall be conducted at least once in each of the following semiannual periods each year of permit coverage: January through June, and July through December.
d. e. Documentation explaining a facility's
inability to obtain a sample (including dates/times dates and times
the outfalls were viewed and/or or sampling was attempted), of no
rain event, or of no "measurable" storm event shall be maintained
with the SWPPP. Acceptable documentation includes, but is not limited to, NCDC
National Climatic Data Center (NCDC) weather station data, local weather
station data, facility rainfall logs, and other appropriate supporting data.
f. Representative outfalls - substantially identical discharges. If the facility has two or more outfalls that discharge substantially identical effluents, based on similarities of the industrial activities, significant materials, size of drainage areas, and stormwater management practices occurring within the drainage areas of the outfalls, the permittee may conduct monitoring on the effluent of just one of the outfalls and report that the observations also apply to the substantially identical outfall or outfalls. The substantially identical outfall monitoring provisions apply to quarterly visual monitoring, benchmark monitoring, and impaired waters monitoring (both those with and without an approved TMDL). The substantially identical outfall monitoring provisions are not available for numeric effluent limits monitoring.
The permittee shall include the following information in the SWPPP:
(1) The locations of the outfalls;
(2) Why the outfalls are expected to discharge substantially identical effluents, including evaluation of monitoring data where available; and
(3) Estimates of the size of the drainage area (in square feet) for each of the outfalls.
3. Adverse climatic conditions waiver. When adverse weather conditions prevent the collection of samples, a substitute sample may be taken during a qualifying storm event in the next monitoring period. Adverse weather conditions are those that are dangerous or create inaccessibility for personnel, and may include such things as local flooding, high winds, electrical storms, or situations that otherwise make sampling impracticable, such as drought or extended frozen conditions. Unless specifically stated otherwise, this waiver may be applied to any monitoring required under this permit.
4. Inactive and unstaffed sites (including temporarily inactive sites).
a. A waiver of the quarterly visual assessments, routine facility inspections, and monitoring requirements (including benchmark, effluent limitation, and impaired waters monitoring) may be granted by the board at a facility that is both inactive and unstaffed, as long as the facility remains inactive and unstaffed and there are no industrial materials or activities exposed to stormwater. The owner of such a facility is only required to conduct an annual comprehensive site inspection in accordance with the requirements in Part III E.
b. An inactive and unstaffed sites waiver request shall be submitted to the board for approval and shall include: the name of the facility; the facility's VPDES general permit registration number; a contact person, phone number and email address (if available); the reason for the request; and the date the facility became or will become inactive and unstaffed. The waiver request shall be signed and certified in accordance with Part II K. If this waiver is granted, a copy of the request and the board's written approval of the waiver shall be maintained with the SWPPP.
c. If circumstances change and industrial materials or activities become exposed to stormwater, or the facility becomes either active or staffed, the permittee shall notify the department within 30 days, and all quarterly visual assessments, routine facility inspections, and monitoring requirements shall be resumed immediately.
d. The board retains the right to revoke this waiver when it is determined that the discharge is causing, has a reasonable potential to cause, or contributes to a water quality standards violation.
e. Inactive and unstaffed facilities covered under Sector G (Metal Mining) and Sector H (Coal Mines and Coal Mining-Related Facilities) are not required to meet the "no industrial materials or activities exposed to stormwater" standard to be eligible for this waiver, consistent with the conditional exemption requirements established in Part IV Sector G and Part IV Sector H.
4. 5. Reporting monitoring results.
a. Reporting to the department. Depending on the types of
monitoring required at a permitted facility, monitoring results may have to be submitted
to the department, or they may only have to be kept with the SWPPP. The
permittee shall follow the reporting requirements and deadlines below for the
types of monitoring that apply to the facility:

Retain results with SWPPP - do not submit unless requested to do so by the department. |
|
|
Permittees that are required to submit monitoring shall
submit results for each outfall associated with industrial activity according
to the requirements of Part II C. For each outfall sampled, one signed
discharge monitoring report (DMR) form shall be submitted to the department per
storm event sampled. For representative outfalls, the sampled outfall will
be reported on the DMR, and the outfalls that are representative of the sampled
outfall will be listed in the comment section of the DMR. Signed DMRs are not
required for each of the outfalls that are representative of the sampled
outfall.
b. Additional reporting. In addition to filing submitting
copies of discharge monitoring reports in accordance with Part II C, permittees
with at least one stormwater discharge associated with industrial activity
through a regulated municipal separate storm sewer system (MS4), or a
municipal system designated by the director, must shall submit
signed copies of DMRs to the MS4 operator at the same time as the reports
are submitted to the department. Permittees not required to report
monitoring data and permittees that are not otherwise required to monitor their
discharges need not comply with this provision.
c. Significant digits. The permittee shall report at least the same number of significant digits as a numeric effluent limitation or TMDL wasteload allocation for a given parameter; otherwise, at least two significant digits shall be reported for a given parameter. Regardless of the rounding convention used by the permittee (i.e., five always rounding up or to the nearest even number), the permittee shall use the convention consistently and shall ensure that consulting laboratories employed by the permittee use the same convention.
5. 6. Corrective actions.
a. Data exceeding benchmarks concentration values.
(1) If the benchmark monitoring result exceeds the benchmark
concentration value for that parameter, the permittee must shall
review the SWPPP and modify it as necessary to address any deficiencies that
caused the exceedance. Revisions to the SWPPP must shall be
completed within 30 days after an exceedance is discovered. When [ BMPs
control measures ] need to be modified or added (distinct from
regular preventive maintenance of existing [ BMPs control
measures ] described in Part III C), implementation must shall
be completed before the next anticipated storm event if possible, but no later
than 60 days after the exceedance is discovered, or as otherwise provided or
approved by the department. In cases where construction is necessary to
implement [ BMPs control measures ], the permittee
shall include a schedule in the SWPPP that provides for the completion of the
[ BMPs control measures ] as expeditiously as
practicable, but no later than three years after the exceedance is discovered.
Where a construction compliance schedule is included in the SWPPP, the plan
shall include appropriate nonstructural and/or and temporary
controls to be implemented in the affected portion(s) of the facility prior to
completion of the permanent [ BMP control measure ].
Any [ BMP control measure ] modifications must shall
be documented and dated, and retained with the SWPPP, along with the amount of
time taken to modify the applicable [ BMPs control measures ]
or implement additional [ BMPs control measures ].
(2) Natural background pollutant levels. If the concentration of a pollutant exceeds a benchmark concentration value, and the permittee determines that exceedance of the benchmark is attributable solely to the presence of that pollutant in the natural background, corrective action is not required provided that:
(a) The concentration of the benchmark monitoring result is less than or equal to the concentration of that pollutant in the natural background;
(b) The permittee documents and maintains with the SWPPP the supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background pollutant levels. The supporting rationale shall include any data previously collected by the facility or others (including literature studies) that describe the levels of natural background pollutants in the facility's stormwater discharges; and
(c) The permittee notifies the department on the benchmark monitoring DMR that the benchmark exceedances are attributable solely to natural background pollutant levels.
Natural background pollutants include those substances that are naturally occurring in soils or groundwater. Natural background pollutants do not include legacy pollutants from earlier activity on the facility's site, or pollutants in run-on from neighboring sources that are not naturally occurring.
b. Corrective actions. The permittee must shall
take corrective action whenever:
(1) Routine facility inspections, comprehensive site
compliance evaluations, inspections by local, state or federal officials, or
any other process, observation or event result in a determination that
modifications to the stormwater control measures are necessary to meet the
permit requirements; [ or ]
(2) There is any exceedance of an effluent limitation
(including coal pile runoff), or TMDL wasteload allocation, or a
reduction required by a local ordinance established by a municipality to meet
Chesapeake Bay TMDL requirements; [ or ]
(3) The department determines, or the permittee becomes aware, that the stormwater control measures are not stringent enough for the discharge to meet applicable water quality standards.
The permittee must shall review the SWPPP and
modify it as necessary to address any deficiencies. Revisions to the SWPPP must
shall be completed within 30 days following the discovery of the
deficiency. When [ BMPs control measures ] need to be
modified or added (distinct from regular preventive maintenance of existing
[ BMPs control measures ] described in Part III C),
implementation must shall be completed before the next
anticipated storm event if possible, but no later than 60 days after the
deficiency is discovered, or as otherwise provided or approved by the
department. In cases where construction is necessary to implement [ BMPs
control measures ], the permittee shall include a schedule in the
SWPPP that provides for the completion of the [ BMPs control
measures ] as expeditiously as practicable, but no later than three
years after the deficiency is discovered. Where a construction compliance
schedule is included in the SWPPP, the plan shall include appropriate
nonstructural and/or and temporary controls to be implemented in
the affected portion(s) of the facility prior to completion of the permanent
[ BMP control measure ]. The amount of time taken to
modify a [ BMP control measure ] or implement
additional [ BMPs control measures ] must shall
be documented in the SWPPP.
Any corrective actions taken must shall be documented
and retained with the SWPPP. Reports of corrective actions must shall
be signed in accordance with Part II K.
c. Follow-up monitoring and reporting. If at any time
monitoring results indicate that discharges from the facility exceed an
effluent limitation or a TMDL wasteload allocation, or the department
determines that discharges from the facility are causing or contributing to an
exceedance of a water quality standard, immediate steps must shall
be taken to eliminate the exceedances in accordance with the above Part I A 5
6 b (Corrective actions). Within 30 calendar days of implementing the
relevant corrective action(s) (or during the next qualifying runoff event,
should none occur within 30 calendar days) follow-up monitoring must be
undertaken to verify that the BMPs that were modified are effectively
protecting water quality. Follow-up monitoring need only be conducted for
pollutant(s) with prior exceedances unless there are reasons to believe that
facility modifications may have reduced pollutant prevention or removal
capacity for other pollutants of concern. The follow-up monitoring data must be
submitted to the department no later than 30 days after the results are
received. If the follow-up monitoring value does not exceed the effluent limitation
or other relevant standard, no additional follow-up monitoring is required for
this corrective action. Should the follow-up monitoring indicate that the
effluent limitation, TMDL wasteload allocation, water quality standard or other
relevant standard is still being exceeded, an exceedance report must
shall be submitted to the department no later than 30 days after the
follow-up monitoring results are received. The following information must
shall be included in the report: general permit registration
number; facility name, address, and location; receiving water;
monitoring data from this and the preceding monitoring event(s) event;
an explanation of the situation; description of what has been done and the
intended actions (should the corrective actions not yet be complete) to further
reduce pollutants in the discharge; and an appropriate contact name and phone
number. Additional follow-up monitoring must be continued at an appropriate
frequency, but no less often than quarterly, until the discharge no longer
exceeds the standard.

2. Releases of hazardous substances or oil in excess of
reportable quantities. The discharge of hazardous substances or oil in the stormwater
discharge(s) from the facility shall be prevented or minimized in accordance
with the stormwater pollution prevention plan for the facility. This permit
does not authorize the discharge of hazardous substances or oil resulting from
an on-site spill. This permit does not relieve the permittee of the reporting
requirements of 40 CFR Part 110 (2007), 40 CFR Part 117 (2007),
and 40 CFR Part 302 (2007) or § 62.1-44.34:19 of the Code of Virginia.
Where a release containing a hazardous substance or oil in an
amount equal to or in excess of a reportable quantity established under either
40 CFR Part 110 (2007), 40 CFR Part 117 (2007), or 40 CFR
Part 302 (2007) occurs during a 24-hour period:
a. The permittee is required to notify the department in accordance with the requirements of Part II G as soon as he has knowledge of the discharge;
b. Where a release enters a municipal separate storm sewer system (MS4), the permittee shall also notify the owner of the MS4; and
c. The stormwater pollution prevention plan required under Part III shall be reviewed to identify measures to prevent the reoccurrence of such releases and to respond to such releases, and the plan shall be modified where appropriate.
3. Colocated industrial activity. If the facility has industrial activities occurring on-site which are described by any of the activities in Part IV of the permit (9VAC25-151-90 et seq.), those industrial activities are considered to be colocated industrial activities. Stormwater discharges from colocated industrial activities are authorized by this permit, provided that the permittee complies with any and all additional pollution prevention plan and monitoring requirements from Part IV applicable to that particular colocated industrial activity. The permittee shall determine which additional pollution prevention plan and monitoring requirements are applicable to the colocated industrial activity by examining the narrative descriptions of each coverage section (Discharges covered under this section).
4. The stormwater discharges authorized by this permit may be combined with other sources of stormwater which are not required to be covered under a VPDES permit, so long as the combined discharge is in compliance with this permit.
5. There shall be no discharge of waste, garbage, or
floating solids or visible foam debris in other than trace amounts.
6. Salt storage piles or piles containing salt. Storage
piles of salt or piles containing salt used for deicing or other commercial or
industrial purposes shall be enclosed or covered to prevent exposure to
precipitation. The permittee shall implement appropriate measures (e.g., good
housekeeping, diversions, containment) to minimize exposure resulting from
adding to or removing materials from the pile. All salt storage piles shall be
located on an impervious surface. All runoff from the pile, and/or runoff that
comes in contact with salt, including under drain systems, shall be collected
and contained within a bermed basin lined with concrete or other impermeable
materials, or within an underground storage tank(s), or within an above ground
storage tank(s), or disposed of through a sanitary sewer (with the permission
of the treatment facility). A combination of any or all of these methods may be
used. In no case shall salt contaminated stormwater be allowed to discharge
directly to the ground or to state waters. [ 6. Approval for
coverage under this general permit does not relieve the permittee of the
responsibility to comply with any other applicable federal, state, or local
statute, ordinance, or regulation. ]
[ 7. 6. ] Discharges to waters subject to
TMDL wasteload allocations.
Facilities a. Owners of facilities that are a
source of the specified pollutant of concern to waters for which a "total
maximum daily load" (TMDL) wasteload allocation has been established
by the board and approved by EPA prior to the term of this permit
shall incorporate measures and controls into the SWPPP required by Part III
that are consistent with the assumptions and requirements of the TMDL. The
department will provide written notification to the owner that a facility is
subject to the TMDL requirements. The facility's SWPPP shall specifically
address any conditions or requirements included in the TMDL that are applicable
to discharges from the facility. If the TMDL establishes a specific numeric
wasteload allocation that applies to discharges from the facility, the owner
shall perform any required monitoring in accordance with Part I A 1 c (3), and
implement [ BMPs control measures ] designed to meet
that allocation.
b. Facilities in the Chesapeake Bay watershed.
(1) Owners of facilities in the Chesapeake Bay watershed
shall monitor their discharges for total suspended solids (TSS), total nitrogen
(TN), and total phosphorus (TP) to characterize the contributions from their
facility's specific industrial sector for these parameters [ ,. ]
After the facility is granted coverage under the permit, samples shall be
collected during each of the first four monitoring periods (i.e., the first two
years of permit coverage). Monitoring periods are specified in Part I A 2.
Samples shall be collected and analyzed in accordance with Part I A 2.
Monitoring results shall be reported in accordance with Part I A 5 and Part II
C, and retained in accordance with Part II B.
[ (2) Facilities that were covered under the 2009 industrial stormwater general permit that sampled for TSS, TN, or TP may use applicable sampling data from the last two monitoring periods of that permit and the first two monitoring periods of this permit to satisfy the four consecutive monitoring periods requirement.
(3) Chesapeake Bay TMDL wasteload allocations and Chesapeake Bay TMDL action plans.
(a) EPA's Chesapeake Bay TMDL (December 29, 2010) includes wasteload allocations for VPDES permitted industrial stormwater facilities as part of the regulated stormwater aggregate load. EPA used data submitted by Virginia with the Phase I Chesapeake Bay TMDL Watershed Implementation Plan, including the number of industrial stormwater permits per county and the number of urban acres regulated by industrial stormwater permits, as part of their development of the aggregate load. Aggregate loads for industrial stormwater facilities were appropriate because actual facility loading data were not available to develop individual facility wasteload allocations.
Virginia estimated the loadings from industrial stormwater facilities using actual and estimated facility acreage information and TP, TN, and TSS loading values from the Northern Virginia Planning District Commission (NVPDC) Guidebook for Screening Urban Nonpoint Pollution Management Strategies (Annandale, VA November 1979), prepared for the Metropolitan Washington Council of Governments. The loading values used were as follows:
TP - High (80%) imperviousness industrial; 1.5 lb/ac/yr
TN - High (80%) imperviousness industrial; 12.3 lb/ac/yr
TSS - High (80%) imperviousness industrial; 440 lb/ac/yr
The actual facility area information and the TP, TN, and TSS data collected for this permit will be used by the board to quantify the nutrient and sediment loads from VPDES permitted industrial stormwater facilities and will be submitted to EPA to aid in further refinements to its Chesapeake Bay TMDL model. The loading information will also be used by the board to determine any additional load reductions needed for industrial stormwater facilities for the next reissuance of this permit.
(b) Data analysis and Chesapeake Bay TMDL action plans. The permittee shall analyze the nutrient and sediment data collected in accordance with subdivision 7 b (1) of this subsection to determine if additional action is needed for this permit term. The permittee shall average the data collected at the facility for each of the pollutants of concern (POC) (e.g., TP, TN, and TSS) and compare the results to the loading values for TP, TN, and TSS presented in subdivision 7 b (3) (a) of this subsection. To calculate the facility loadings, the permittee may use either (i) actual annual average rainfall data for the facility location (in inches/year), or the Virginia annual average rainfall of 44.3 inches/year; or (ii) another method approved by the board.
The following formula may be used to determine the loading value:
L = (0.2263 x R x C) / A
where:
L = the POC loading value (lb/acre/year)
R = the annual average rainfall (inches/year)
C = the POC average concentration of all facility samples (mg/L)
A = the facility industrial activity area (acres)
(c) If the calculated facility loading value for TP, TN, or TSS is above the loading values for TP, TN, or TSS presented in subdivision 7 b (3) (a) of this subsection, then the permittee shall develop and submit to the board for review and approval a Chesapeake Bay TMDL Action Plan. The plan shall be submitted within 90 days from the end of the second year's monitoring period (by September 28, 2016). The permittee shall implement the approved plan over the remaining term of this permit to achieve all the necessary reductions by June 30, 2024. The action plan shall include:
(i) A determination of the total pollutant load reductions for TP, TN, and TSS (as appropriate) necessary to reduce the annual loads from industrial activities. This shall be determined by calculating the difference between the loading values listed in subdivision 7 b (3) (a) of this subsection, and the average of the sampling data for TP, TN, or TSS (as appropriate) for the entire facility. The reduction applies to the total difference calculated for each pollutant of concern;
(ii) The means and methods, such as management practices and retrofit programs, that will be utilized to meet the required reductions determined in subdivision 7 b (3) (c) (i) of this subsection, and a schedule to achieve those reductions by June 30, 2024. The schedule should include annual benchmarks to demonstrate the ongoing progress in meeting those reductions; and
(iii) The permittee may consider utilization of any pollutant trading or offset program in accordance with §§ 62.1-44.19:20 through 62.1-44.19:23 of the Code of Virginia, governing trading and offsetting, to meet the required reductions.
(d) A permittee required to develop and implement a Chesapeake Bay TMDL Action Plan shall submit an annual report to the department by June 30 of each year describing the progress in meeting the required reductions. ]
[ 7. 8. ] Discharges through
a [ Virginia Stormwater Management Program (VSMP) ]
regulated MS4 to waters subject to the Chesapeake Bay TMDL. [ Any
In addition to the requirements of this permit, any ] facility with
industrial activity discharges through a [ VSMP ]
regulated MS4 that is notified by the MS4 operator that the locality has
adopted ordinances to meet the Chesapeake Bay TMDL shall incorporate measures
and controls into its SWPPP to comply with [ the local
ordinances applicable local TMDL ordinance requirements ].
[ 8. 9. ] Expansion of
facilities that discharge to waters subject to the Chesapeake Bay TMDL.
[ a. After November 29, 2010, (the date of ] Virginia's
Phase I Chesapeake Bay TMDL Watershed Implementation Plan [ (November
29, 2010 ] ), [ states that ] the wasteloads
from any expansion of an existing permitted facility discharging stormwater in
the Chesapeake Bay watershed cannot exceed the nutrient and sediment loadings
that were discharged from the expanded portion of the land prior to the land being
developed for the [ expanded ] industrial
activity.
[ b. The a. For any industrial activity
area expansions (i.e., construction activities, including clearing, grading,
and excavation activities) that commence on or after July 1, 2014, (the
effective date of this permit), the ] permittee shall document in
the SWPPP the information and calculations used to determine the nutrient and
sediment loadings discharged from the expanded [ portion of
the ] land [ area ] prior to the
land being developed [ , ] and the measures and
controls that were employed to meet the no net increase of stormwater nutrient
and sediment load as a result of the expansion of the industrial activity. [ Any
land disturbance that is exempt from permitting under the VPDES construction
stormwater general permit regulation (9VAC25-880) is exempt from this
requirement. ]
[ c. b. ] The permittee may
use the VSMP water quality design criteria to meet the requirements of [ subdivisions
a and b subdivision 9 a ] of this subsection. Under this
criteria, the total phosphorus load shall not exceed the greater of: (i) the
total phosphorus load that was discharged from the expanded portion of the land
prior to the land being developed for the industrial activity or (ii) 0.41
pounds per acre per year. Compliance with the water quality design criteria may
be determined utilizing the Virginia Runoff Reduction Method or another
equivalent methodology approved by the board. Design specifications and
pollutant removal efficiencies for [ specific ] BMPs
can be found on the Virginia [ Stormwater Stormwater ]
BMP Clearinghouse website at http://www.vwrrc.vt.edu/swc.
[ d. The facility owner may acquire nutrient
credits c. The permittee may consider utilization of any pollutant
trading or offset program in accordance with §§ 62.1-44.19:20 through
62.1-44.19:23 of the Code of Virginia, governing trading and offsetting, ]
to meet the no net increase requirement [ in accordance with
applicable regulations ].
8. [ 9. 10. ] Water
quality protection. The discharges authorized by this permit shall be
controlled as necessary to meet applicable water quality standards. The
permittee shall employ an iterative, BMP-based program to select, install,
implement and maintain best management practices (BMPs) at the facility designed
to minimize pollutants in the stormwater discharges, and to address any
exceedance of any applicable water quality standard, effluent limitation, or
TMDL wasteload allocation. The board expects that compliance with the
conditions in this permit will control discharges as necessary to meet
applicable water quality standards. If there is evidence indicating that the
stormwater discharges authorized by this permit are causing, have the
reasonable potential to cause, or are contributing to an excursion above an
applicable water quality standard, an excursion above a TMDL wasteload
allocation, or are causing downstream pollution (as defined in § 62.1-44.3 of
the Code of Virginia), the board may require the permittee to take corrective
action in accordance with Part I A 5 b and c, and include and implement
appropriate controls in the SWPPP to correct the problem, or may require the
permittee to obtain an individual permit in accordance with 9VAC25-31-170 B 3.
9. Adding/deleting [ 10. 11. ]
Adding or deleting stormwater outfalls. The permittee may add new and/or
or delete existing stormwater outfalls at the facility as necessary/appropriate
necessary and appropriate. The permittee shall update the SWPPP and notify
the department of all outfall changes within 30 days of the change. The
permittee shall submit a copy of the updated SWPPP site map with [ their
this ] notification.
10. [ 11. 12. ]
Antidegradation requirements for new or increased discharges to high quality
waters. Facilities that add new outfalls, or increase their discharges from
existing outfalls that discharge directly to high quality waters designated
under Virginia's water quality standards antidegradation policy under
9VAC25-260-30 A 2 may be notified by the department that additional control
measures, or other permit conditions are necessary to comply with the
applicable antidegradation requirements, or may be notified that an individual
permit is required in accordance with 9VAC25-31-170 B 3.
[ 12. 13. ] If the permittee
discharges to surface waters through a municipal separate storm sewer system
(MS4), the permittee shall, within 30 days of coverage under this general
permit, notify the owner of the MS4 in writing of the existence of the discharge
and provide the following information: the name of the facility, a contact
person and phone number, the location of the discharge, the nature of the
discharge, and the facility's VPDES general permit registration number. A copy
of such notification shall be provided to the department.
[ 13. 14. ] Termination of
permit coverage.
a. The owner may terminate coverage under this general permit by filing a complete notice of termination. The notice of termination may be filed after one or more of the following conditions have been met:
(1) Operations have ceased at the facility and there are no longer discharges of stormwater associated with industrial activity from the facility;
(2) A new owner has assumed responsibility for the facility (Note: A notice of termination does not have to be submitted if a VPDES Change of Ownership Agreement Form has been submitted);
(3) All stormwater discharges associated with industrial activity have been covered by an individual VPDES permit; or
(4) Termination of coverage is being requested for another reason, provided the board agrees that coverage under this general permit is no longer needed.
b. The notice of termination shall contain the following information:
(1) Owner's name, mailing address, telephone number, and email address (if available);
(2) Facility name and location;
(3) VPDES industrial stormwater general permit registration number;
(4) The basis for submitting the notice of termination, including:
(a) A statement indicating that a new owner has assumed responsibility for the facility;
(b) A statement indicating that operations have ceased at the facility, and there are no longer discharges of stormwater associated with industrial activity from the facility;
(c) A statement indicating that all stormwater discharges associated with industrial activity have been covered by an individual VPDES permit; or
(d) A statement indicating that termination of coverage is being requested for another reason (state the reason); and
(5) The following certification: "I certify under penalty of law that all stormwater discharges associated with industrial activity from the identified facility that are authorized by this VPDES general permit have been eliminated, or covered under a VPDES individual permit, or that I am no longer the owner of the industrial activity, or permit coverage should be terminated for another reason listed above. I understand that by submitting this notice of termination, that I am no longer authorized to discharge stormwater associated with industrial activity in accordance with the general permit, and that discharging pollutants in stormwater associated with industrial activity to surface waters is unlawful where the discharge is not authorized by a VPDES permit. I also understand that the submittal of this notice of termination does not release an owner from liability for any violations of this permit or the Clean Water Act."
c. The notice of termination shall be signed in accordance with Part II K.
d. The notice of termination shall be submitted to the DEQ regional office serving the area where the industrial facility is located.

N. Effect of a permit. This permit does not convey any property rights in either real or personal property or any exclusive privileges, nor does it authorize any injury to private property or invasion of personal rights, or any infringement of federal, state or local law or regulations.
O. State law. Nothing in this permit shall be construed to preclude the institution of any legal action under, or relieve the permittee from any responsibilities, liabilities, or penalties established pursuant to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except as provided in permit conditions on "bypassing" (Part II U), and "upset" (Part II V) nothing in this permit shall be construed to relieve the permittee from civil and criminal penalties for noncompliance.
P. Oil and hazardous substance liability. Nothing in this permit shall be construed to preclude the institution of any legal action or relieve the permittee from any responsibilities, liabilities, or penalties to which the permittee is or may be subject under §§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water Control Law.
Q. Proper operation and maintenance. The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes effective plant performance, adequate funding, adequate staffing, and adequate laboratory and process controls, including appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by the permittee only when the operation is necessary to achieve compliance with the conditions of this permit.
R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of treatment or management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such materials from entering state waters.
S. Duty to mitigate. The permittee shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this permit which has a reasonable likelihood of adversely affecting human health or the environment.
T. Need to halt or reduce activity not a defense. It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit.
U. Bypass.
1. "Bypass" means the intentional diversion of waste streams from any portion of a treatment facility. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Part II U 2 and 3.
2. Notice.
a. Anticipated bypass. If the permittee knows in advance of the need for a bypass, prior notice shall be submitted, if possible at least 10 days before the date of the bypass.
b. Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II I.
3. Prohibition of bypass.
a. Bypass is prohibited, and the board may take enforcement action against a permittee for bypass, unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and
(3) The permittee submitted notices as required under Part II U 2.
b. The board may approve an anticipated bypass, after considering its adverse effects, if the board determines that it will meet the three conditions listed above in Part II U 3 a.
V. Upset.
1. An upset constitutes an affirmative defense to an action brought for noncompliance with technology based permit effluent limitations if the requirements of Part II V 2 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a final administrative action subject to judicial review.
2. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:
a. An upset occurred and that the permittee can identify the cause(s) of the upset;
b. The permitted facility was at the time being properly operated;
c. The permittee submitted notice of the upset as required in Part II I; and
d. The permittee complied with any remedial measures required under Part II S.
3. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof.
W. Inspection and entry. The permittee shall allow the director, or an authorized representative, upon presentation of credentials and other documents as may be required by law, to:
1. Enter upon the permittee's premises where a regulated facility or activity is located or conducted, or where records must be kept under the conditions of this permit;
2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of this permit;
3. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this permit; and
4. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as otherwise authorized by the Clean Water Act and the State Water Control Law, any substances or parameters at any location.
For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency.
X. Permit actions. Permits may be modified, revoked and reissued, or terminated for cause. The filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any permit condition.
Y. Transfer of permits.
1. Permits are not transferable to any person except
after notice to the department. Except as provided in Part II Y 2, a permit
may be transferred by the permittee to a new owner or operator only if the
permit has been modified or revoked and reissued, or a minor modification made,
to identify the new permittee and incorporate such other requirements as may be
necessary under the State Water Control Law and the Clean Water Act.
2. As an alternative to transfers under Part II Y 1, Coverage
under this permit may be automatically transferred to a new permittee if:
a. 1. The current permittee notifies the
department [ at least within ] 30 days [ in
advance ] of the proposed transfer of the title to the facility or
property, unless permission for a later date has been granted by the board;
b. 2. The notice includes a written agreement
between the existing and new permittees containing a specific date for transfer
of permit responsibility, coverage, and liability between them; and
c. 3. The board does not notify the existing
permittee and the proposed new permittee of its intent to modify or revoke
and reissue deny the new permittee coverage under the permit. If
this notice is not received, the transfer is effective on the date specified in
the agreement mentioned in Part II Y 2 b.
Z. Severability. The provisions of this permit are severable, and if any provision of this permit or the application of any provision of this permit to any circumstance, is held invalid, the application of such provision to other circumstances, and the remainder of this permit, shall not be affected thereby.

industry practices. The BMPs shall be [ is intended to document the
selection, design, and installation of ] control measures
[ selected, designed, installed, implemented and maintained in
accordance with good engineering practices and manufacturer's specifications,
including BMPs, ] to eliminate or reduce the pollutants in all stormwater
discharges from the facility. The SWPPP shall also include any control
measures necessary for the stormwater discharges, and to meet
applicable effluent limitations and water quality standards.
The SWPPP requirements of this general permit may be fulfilled, in part, by incorporating by reference other plans or documents such as a spill prevention control and countermeasure (SPCC) plan developed for the facility under § 311 of the Clean Water Act, or best management practices (BMP) programs otherwise required for the facility, provided that the incorporated plan meets or exceeds the plan requirements of Part III B (Contents of the Plan). All plans incorporated by reference into the SWPPP become enforceable under this permit. If a plan incorporated by reference does not contain all of the required elements of the SWPPP of Part III B, the permittee shall develop the missing SWPPP elements and include them in the required plan.
A. Deadlines for plan preparation and compliance.
1. Facilities that were covered under the 2004 2009
Industrial Stormwater General Permit. Owners of facilities that were covered
under the 2004 2009 Industrial Stormwater General Permit who are

running onto the facility impacts the facility's stormwater discharges.;
and
(13) Locations of all stormwater monitoring points.
d. Receiving waters and wetlands. The name of all surface waters receiving discharges from the site, including intermittent streams, dry sloughs, and arroyos. Provide a description of wetland sites that may receive discharges from the facility. If the facility discharges through a municipal separate storm sewer system (MS4), identify the MS4 operator, and the receiving water to which the MS4 discharges.
3. Summary of potential pollutant sources. The plan shall identify each separate area at the facility where industrial materials or activities are exposed to stormwater. Industrial materials or activities include, but are not limited to: material handling equipment or activities, industrial machinery, raw materials, industrial production and processes, intermediate products, byproducts, final products, and waste products. Material handling activities include, but are not limited to: the storage, loading and unloading, transportation, disposal, or conveyance of any raw material, intermediate product, final product or waste product. For each separate area identified, the description shall include:
a. Activities in the area. A list of the industrial
activities exposed to stormwater (e.g., material storage, equipment
fueling and cleaning, cutting steel beams); and
b. Pollutants. A list of the associated pollutant(s) or
pollutant constituents (e.g., crankcase oil, zinc, sulfuric acid, cleaning
solvents, etc.) for associated with each industrial
activity. The pollutant list shall include all significant materials handled,
treated, stored or disposed that have been exposed to stormwater in the three
years prior to the date this SWPPP was prepared or amended. The list shall
include any hazardous substances or oil at the facility.
4. c. Spills and leaks. The SWPPP shall clearly
identify areas where potential spills and leaks that can contribute pollutants
to stormwater discharges can occur and their corresponding outfalls. The plan
shall include a list of significant spills and leaks of toxic or hazardous
pollutants that actually occurred at exposed areas, or that drained to a stormwater
conveyance during the three-year period prior to the date this SWPPP was
prepared or amended. The list shall be updated if significant spills or leaks
occur in exposed areas of the facility during the term of the permit.
Significant spills and leaks include, but are not limited to, releases
of oil or hazardous substances in excess of reportable quantities, and may
also include releases of oil or hazardous substances that are not in excess of
reporting requirements.
5. d. Sampling data. The plan shall include a
summary of existing stormwater discharge sampling data taken at the facility.
The summary shall include, at a minimum, any data collected during the previous
permit term.
6. 4. Stormwater controls.
a. Control measures [ (BMPs) ]
shall be implemented for all the areas identified in Part III B 3 (summary of
potential pollutant sources) to prevent or control pollutants in stormwater
discharges from the facility. All reasonable steps shall be taken to control
or address the quality of discharges from the site that may not originate at
the facility. Regulated stormwater discharges from the facility include stormwater
runon that commingles with stormwater discharges associated with industrial
activity at the facility. The SWPPP shall describe the type, location and
implementation of all BMPs control measures for each area where
industrial materials or activities are exposed to stormwater.
Selection of BMPs control measures shall take
into consideration:
(1) That preventing stormwater from coming into contact with polluting materials is generally more effective, and less costly, than trying to remove pollutants from stormwater;
(2) BMPs Control measures generally shall be
used in combination with each other for most effective water quality
protection;
(3) Assessing the type and quantity of pollutants, including their potential to impact receiving water quality, is critical to designing effective control measures;
(4) That minimizing impervious areas at the facility can reduce runoff and improve groundwater recharge and stream base flows in local streams (however, care must be taken to avoid ground water contamination);
(5) Flow attenuation by use of open vegetated swales and natural depressions can reduce in-stream impacts of erosive flows;
(6) Conservation or restoration of riparian buffers will help protect streams from stormwater runoff and improve water quality; and
(7) Treatment interceptors (e.g., swirl separators and sand filters) may be appropriate in some instances to minimize the discharge of pollutants.
b. Control measures (Nonnumeric technology-based effluent
limits) Nonnumeric technology-based effluent limits. The permittee
shall implement the following types of BMPs control measures to
prevent and control pollutants in the stormwater discharges from the facility,
unless it can be demonstrated and documented that such controls are not
relevant to the discharges (e.g., there are no storage piles containing salt).
(1) Good housekeeping. The permittee shall keep clean all
exposed areas of the facility that are potential sources of pollutants to stormwater
discharges. Typical problem areas include areas around trash containers,
storage areas, loading docks, and vehicle fueling and maintenance areas. The
plan shall include a schedule for regular pickup and disposal of waste
materials, along with routine inspections for leaks and conditions of drums,
tanks and containers. The introduction of raw, final or waste materials to
exposed areas of the facility shall be minimized to the maximum extent
practicable. The generation of dust, along with off-site vehicle tracking of
raw, final or waste materials, or sediments, shall be minimized to the maximum
extent practicable.
(2) Eliminating and minimizing exposure. To the extent
practicable, industrial materials and activities manufacturing,
processing, and material storage areas (including loading and unloading,
storage, disposal, cleaning, maintenance, and fueling operations) shall be
located inside, or protected by a storm-resistant covering to prevent exposure
to rain, snow, snowmelt, and runoff. Note: Eliminating exposure at all
industrial areas may make the facility eligible for the "Conditional
Exclusion for No Exposure" provision of 9VAC25-31-120 E, thereby
eliminating the need to have a permit.
(3) Preventive maintenance. The permittee shall have a
preventive maintenance program that includes regular inspection, testing,
maintenance and repairing of all industrial equipment and systems to avoid breakdowns
or failures situations that could result in leaks, spill spills
and other releases of pollutants in stormwater discharged from the facility.
This program is in addition to the specific BMP control measure
maintenance required under Part III C (Maintenance of BMPs) (Maintenance
of control measures).
(4) Spill prevention and response procedures. The plan shall
describe the procedures that will be followed for preventing and responding to
spills and leaks., including:
(a) Preventive measures include, such as
barriers between material storage and traffic areas, secondary containment
provisions, and procedures for material storage and handling.;
(b) Response procedures shall include, including
notification of appropriate facility personnel, emergency agencies, and
regulatory agencies, and procedures for stopping, containing and cleaning up
spills. Measures for cleaning up hazardous material spills or leaks shall be
consistent with applicable RCRA regulations at 40 CFR Part 264 (2007)
and 40 CFR Part 265 (2007). Employees who may cause, detect or respond
to a spill or leak shall be trained in these procedures and have necessary
spill response equipment available. If possible, one of these individuals shall
be a member of the Pollution Prevention Team.;
(c) Procedures for plainly labeling containers (e.g., "used oil," "spent solvents," "fertilizers and pesticides," etc.) that could be susceptible to spillage or leakage to encourage proper handling and facilitate rapid response if spills or leaks occur; and
(c) (d) Contact information for individuals and
agencies that must be notified in the event of a spill shall be included in the
SWPPP, and in other locations where it will be readily available.
(5) Routine facility inspections. Facility personnel who
possess the knowledge and skills to assess conditions and activities that could
impact stormwater quality at the facility, and who can also evaluate the
effectiveness of BMPs shall regularly inspect all areas of the facility where
industrial materials or activities are exposed to stormwater. These inspections
are in addition to, or as part of, the comprehensive site evaluation required
under Part III E. At least one member of the Pollution Prevention Team shall
participate in the routine facility inspections.
The inspection frequency shall be specified in the plan
based upon a consideration of the level of industrial activity at the facility,
but shall be a minimum of quarterly unless more frequent intervals are
specified elsewhere in the permit or written approval is received from the
department for less frequent intervals. The requirement for routine facility
inspections is waived for facilities that have maintained an active E3/E4
status. At least once each calendar year, the routine facility inspection must
be conducted during a period when a stormwater discharge is occurring.
Any deficiencies in the implementation of the SWPPP that
are found shall be corrected as soon as practicable, but not later than within
30 days of the inspection, unless permission for a later date is granted in
writing by the director. The results of the inspections shall be documented in
the SWPPP, along with the date(s) and description(s) of any corrective actions
that were taken in response to any deficiencies or opportunities for improvement
that were identified.
(5) Salt storage piles or piles containing salt. Storage piles of salt or piles containing salt used for deicing or other commercial or industrial purposes shall be enclosed or covered to prevent exposure to precipitation. The permittee shall implement appropriate measures (e.g., good housekeeping, diversions, containment) to minimize exposure resulting from adding to or removing materials from the pile. All salt storage piles shall be located on an impervious surface. All runoff from the pile, and runoff that comes in contact with salt, including under drain systems, shall be collected and contained within a bermed basin lined with concrete or other impermeable materials, or within an underground storage tank or tanks, or within an above ground storage tank or tanks, or disposed of through a sanitary sewer (with the permission of the owner of the treatment facility). A combination of any or all of these methods may be used. In no case shall salt contaminated stormwater be allowed to discharge directly to the ground or to surface waters.
(6) Employee training. The permittee shall implement a stormwater
employee training program for the facility. [ Employee training
shall take place, at a minimum, once per calendar year. The stormwater employee
training program shall include initial training for new hires. ]
The SWPPP shall include a schedule for all types of necessary training, and
shall document all training sessions and the employees who received the
training. Training shall be provided for all employees who work in areas where
industrial materials or activities are exposed to stormwater, and for employees
who are responsible for implementing activities identified in the SWPPP (e.g.,
inspectors, maintenance personnel, etc.). The training shall cover the
components and goals of the SWPPP, and include such topics as spill response,
good housekeeping, material management practices, [ BMP control
measure ] operation and maintenance, etc. The SWPPP shall include a
summary of any training performed.
(7) Sediment and erosion control. The plan shall identify
areas at the facility that, due to topography, land disturbance (e.g.,
construction, landscaping, site grading), or other factors, have a potential
for soil erosion. The permittee shall identify and implement structural,
vegetative, and/or and stabilization [ BMPs control
measures ] to prevent or control on-site and off-site erosion and
sedimentation. Flow velocity dissipation devices shall be placed at discharge
locations and along the length of any outfall channel if the flows would
otherwise create erosive conditions.
(8) Management of runoff. The plan shall describe the stormwater
runoff management practices (i.e., permanent structural [ BMPs) control
measures) ] for the facility. These types of BMPs control
measures are typically used to divert, infiltrate, reuse, or otherwise
reduce pollutants in stormwater discharges from the site.
Structural [ BMPs control measures ]
may require a separate permit under § 404 of the CWA and the Virginia Water

9VAC25-151-150. Sector G - Metal mining (ore mining and dressing).
A. Discharges covered under this section. The requirements listed under this section apply to stormwater discharges associated with industrial activity from active, temporarily inactive and inactive metal mining and ore dressing facilities including mines abandoned on federal lands, as classified under SIC Major Group 10. Coverage is required for facilities that discharge stormwater that has come into contact with, or is contaminated by, any overburden, raw material, intermediate product, finished product, byproduct, or waste product located on the site of the operation. SIC Major Group 10 includes establishments primarily engaged in mining of ores, developing mines, or exploring for metallic minerals (ores) and also includes ore dressing and beneficiating operations, whether performed at colocated, dedicated mills or at separate mills, such as custom mills. For the purposes of this section, the term "metal mining" includes any of the separate activities listed above. Covered discharges include:
1. All stormwater discharges from inactive facilities;
2. Stormwater discharges from the following areas of active and
temporarily inactive metal mining facilities: waste rock/overburden rock
and overburden piles if composed entirely of stormwater and not combining
with mine drainage; topsoil piles; off-site haul/access haul and
access roads; on-site haul/access haul and access roads constructed
of waste rock/overburden rock and overburden if composed entirely
of stormwater and not combining with mine drainage; on-site haul/access haul
and access roads not constructed of waste rock/overburden/spent rock,
overburden, or spent ore except if mine drainage is used for dust control;
runoff from tailings dams/dikes dams and dikes when not
constructed of waste rock/tailings rock or tailings and no
process fluids are present; runoff from tailings dams/dikes dams or
dikes when constructed of waste rock/tailings rock or tailings
and no process fluids are present if composed entirely of stormwater and not
combining with mine drainage; concentration building if no contact with
material piles; mill site if no contact with material piles; office/administrative
office or administrative building and housing if mixed with stormwater
from industrial area; chemical storage area; docking facility if no excessive
contact with waste product that would otherwise constitute mine drainage;
explosive storage; fuel storage; vehicle/equipment vehicle and
equipment maintenance area/building area and building;
parking areas (if necessary); power plant; truck wash areas if no excessive
contact with waste product that would otherwise constitute mine drainage;
unreclaimed, disturbed areas outside of active mining area; reclaimed areas
released from reclamation bonds prior to December 17, 1990; and partially/inadequately
partially or inadequately reclaimed areas or areas not released from
reclamation bonds;
3. Stormwater discharges from exploration and development of
metal mining and/or and ore dressing facilities; and
4. Stormwater discharges from facilities at mining sites undergoing reclamation.
B. Limitations on coverage. Stormwater discharges from active
metal mining facilities that are subject to the effluent limitation guidelines
for the Ore Mining and Dressing Point Source Category (40 CFR Part 440 (2007)))
are not authorized by this permit.
Note: Discharges that come in contact with overburden/waste
overburden and waste rock are subject to 40 CFR Part 440 (2007),
providing: the discharges drain to a point source (either naturally or as a
result of intentional diversion), and they combine with mine drainage that is
otherwise regulated under 40 CFR Part 440 (2007). Discharges from overburden/waste
overburden and waste rock can be covered under this permit if they are
composed entirely of stormwater and do not combine with sources of mine
drainage that are subject to 40 CFR Part 440 (2007).
C. Special Conditions. Prohibition of nonstormwater
discharges. In addition to the general prohibition of nonstormwater discharges
in Part I B 1, the following discharges are discharge is not
covered by this permit: adit drainage or contaminated springs or seeps.
Contaminated seeps and springs discharging from waste rock dumps that do not
directly result from precipitation events are also not authorized by
this permit.
D. Special definitions. The following definitions are not intended to supersede the definitions of active and inactive mining facilities established by 40 CFR 122.26(b)(14)(iii), and are only for this section of the general permit:
"Active metal mining facility" means a place where work or other related activity to the extraction, removal, or recovery of metal ore is being conducted. For surface mines, this definition does not include any land where grading has returned the earth to a desired contour and reclamation has begun.
"Active phase" means activities including each
step from the extraction through production of a salable product,
removal, or recovery of metal ore. For surface mines, this definition does not
include any land where grading has returned the earth to a desired contour and
reclamation has begun.
"Construction phase" means the building of site access roads and removal of overburden and waste rock to expose mineable minerals. The construction phase is not considered part of "mining operations."
"Exploration and development phase" entails
exploration and land disturbance activities to determine the financial
viability of a site. Development includes the building of site access roads
and removal of overburden and waste rock to expose mineable minerals. The
exploration phase is not considered part of "mining operations."
"Final stabilization" - a site or portion of a site
is "finally stabilized" when: all applicable federal and
state reclamation requirements have been implemented.
1. All soil-disturbing activities at the site have been
completed and either of the two following criteria are met:
a. A uniform (e.g., evenly distributed, without large bare
areas) perennial vegetative cover with a density of 70% of the native
background vegetative cover for the area has been established on all unpaved
areas and areas not covered by permanent structures, or
b. Equivalent permanent stabilization measures (such as the
use of riprap, gabions, or geotextiles) have been employed.
2. When background native vegetation will cover less than
100% of the ground (e.g., arid areas, beaches), the 70% coverage criteria is
adjusted as follows: if the native vegetation covers 50% of the ground, 70% of
50% (0.70 x 0.50 = 0.35) would require 35% total cover for final stabilization.
On a beach with no natural vegetation, no stabilization is required.
"Inactive metal mining facility" means a site or
portion of a site where metal mining and/or or milling occurred
in the past but is not an active facility as defined in this permit, and where
the inactive portion is not covered by an active mining permit issued by the
applicable federal or state governmental agency. An inactive metal
mining facility has an identifiable owner or operator. Sites where mining
claims are being maintained prior to disturbances associated with the
extraction, beneficiation, or processing of mined materials and sites where
minimal activities are undertaken for the sole purpose of maintaining a mining
claim are not considered either active or inactive mining facilities and do not
require a VPDES industrial stormwater permit.
"Mining operation" typically consists of three
the active and temporarily inactive phases, any one of which
individually qualifies as a "mining activity." The phases are the
exploration and development phase, the active phase, and the reclamation phase
and the reclamation phase, but excludes the exploration and construction
phases.
"Reclamation phase" means activities undertaken,
in compliance with applicable mined land reclamation requirements, following
the cessation of the "active phase," intended to return the land
to its premining use. an appropriate post-mining land use in order to
meet applicable federal and state reclamation requirements. The reclamation
phase is considered part of "mining operations."
"Temporarily inactive metal mining facility" means a
site or portion of a site where metal mining and/or or milling
occurred in the past but currently are not being actively undertaken, and the
facility is covered by an active mining permit issued by the applicable federal
or state government agency.
E. Clearing, grading, and excavation activities. Clearing,
grading, and excavation activities being conducted as part of the exploration
and development construction phase of a mining operation
activities are covered under this permit.
1. Management practices for clearing, grading, and excavation activities.
a. Selecting and installing control measures. A combination of erosion and sedimentation control measures are required to achieve maximum pollutant prevention and removal. All control measures shall be properly selected, installed, and maintained in accordance with any relevant manufacturer specifications and good engineering practices.
b. Removal of sediment. If sediment escapes the site,
off-site accumulations of sediment shall be removed at a frequency sufficient
to prevent off-site impacts.
c. b. Good housekeeping. Litter, debris, and
chemicals shall be prevented from becoming a pollutant source in stormwater
discharges.
d. Velocity dissipation. Velocity dissipation devices shall
be placed at discharge locations and along the length of any outfall channel to
provide a nonerosive flow velocity from disturbed areas and from any stormwater
retention or detention facilities to a water course so that the natural
physical and biological characteristics and functions are maintained and protected
(e.g., no significant changes in the hydrological regime of the receiving
water).
e. c. Retention and detention of stormwater
runoff. For drainage locations serving more than one acre, sediment basins and/or
or temporary sediment traps should be used. At a minimum, silt fences,
vegetative buffer strips, or equivalent sediment controls are required for all
down slope boundaries (and for those side slope boundaries deemed appropriate
as dictated by individual site conditions) of the development area unless a
sediment basin providing storage for a calculated volume of runoff from a
two-year, 24-hour storm or 3,600 cubic feet of storage per acre drained is
provided. Sediment shall be removed from sediment traps or sedimentation
ponds when the design capacity has been reduced by 50%.
f. d. Temporary stabilization of disturbed
areas. Stabilization measures shall be initiated immediately in portions of the
site where development activities have temporarily or permanently ceased,
but in no case more than 14 days after the construction activity clearing,
grading, and excavation activities in that portion of the site has have
temporarily or permanently ceased. In arid, semi-arid, and
drought-stricken areas, or in areas subject to snow or freezing conditions,
where initiating perennial vegetative stabilization measures is not possible
within 14 days after mining, exploration, or construction activity has
temporarily or permanently ceased, final temporary vegetative
stabilization measures shall be initiated as soon as possible practicable.
Until full temporary vegetative stabilization is achieved,
interim measures such as erosion control blankets with an appropriate
seed base and tackifiers shall be employed. In areas of the site where
exploration or construction has permanently ceased prior to active mining,
temporary stabilization measures shall be implemented to minimize mobilization
of sediment or other pollutants until such time as the active mining phase commences.
2. Requirements for inspection of clearing, grading, and excavation activities.
a. Inspection frequency. Inspections shall be conducted at
least once every seven calendar days or at least once every 14 calendar days
and within 24 hours of the end of a storm event of 0.5 inches or greater.
Inspection frequency may be reduced to at least once every month if the entire
site is temporarily stabilized, if runoff is unlikely due to winter conditions
(e.g., site is covered with snow, ice, or the ground is frozen) snow
or ice) or frozen conditions, or construction is occurring during seasonal arid
dry periods in arid areas and semi-arid areas.
b. Qualified personnel for inspections. Inspections shall
be conducted by qualified personnel. "Qualified personnel" means a
person knowledgeable in the principles and practice of erosion and sediment
control who possesses the skills to assess conditions at the construction site
that could impact stormwater quality and the effectiveness of any sediment and
erosion control measures selected to control the quality of stormwater
discharges from the clearing, grading, and excavation activities.
c. b. Location of inspections. Inspections shall
include all areas of the site disturbed by clearing, grading, and excavation
activities and areas used for storage of materials that are exposed to
precipitation. Sedimentation and erosion control measures identified in the
SWPPP shall be observed to ensure proper operation. Discharge locations shall
be inspected to ascertain whether erosion control measures are effective in
preventing significant impacts to state surface waters, where
accessible. Where discharge locations are inaccessible, nearby downstream
locations shall be inspected to the extent that such inspections are practicable.
Locations where vehicles enter or exit the site shall be inspected for evidence
of off-site sediment tracking.
d. c. Inspection reports. For each inspection
required above, an inspection report shall be completed. At a minimum, the
inspection report shall include:
(1) The inspection date;
(2) Names, titles, and qualifications of personnel making the inspection;
(3) Weather information for the period since the last inspection (or note if it is the first inspection) including a best estimate of the beginning of each storm event, duration of each storm event, approximate amount of rainfall for each storm event (in inches), and whether any discharges occurred;
(4) Weather information and a description of any discharges occurring at the time of the inspection;
(5) Location(s) of discharges of sediment or other pollutants from the site;
(6) Location(s) of [ BMPs control measures ]
that need to be maintained;
(7) Location(s) of [ BMPs control measures ]
that failed to operate as designed or proved inadequate for a particular
location;
(8) Location(s) where additional [ BMPs control
measures ] are needed that did not exist at the time of inspection;
and
(9) Corrective action(s) required, including any changes to the SWPPP necessary and implementation dates.
A record of each inspection and of any actions taken in accordance with this section shall be retained as part of the SWPPP for at least three years from the date that permit coverage expires or is terminated. The inspection reports shall identify any incidents of noncompliance with the permit conditions. Where a report does not identify any incidents of noncompliance, the report shall contain a certification that the clearing, grading, and excavation activities are in compliance with the SWPPP and this permit. The report shall be signed in accordance with Part II K of the permit.
3. Maintenance of controls for clearing, grading, and
excavation activities.
a. Maintenance of BMPs. All erosion and sediment control
measures and other protective measures identified in the SWPPP shall be
maintained in effective operating condition. If site inspections required by
subdivision 2 of this subsection identify BMPs that are not operating
effectively, maintenance shall be performed as soon as possible and before the
next storm event whenever practicable to maintain the continued effectiveness
of stormwater controls.
b. Modification of BMPs. Existing BMPs need to be modified
or, if additional BMPs are necessary for any reason, implementation shall be
completed before the next storm event whenever practicable. If implementation
before the next storm event is impracticable, the situation shall be documented
in the SWPPP and alternative BMPs shall be implemented as soon as possible.
c. Maintenance of sediment traps and ponds. Sediment from
sediment traps or sedimentation ponds shall be removed when design capacity has
been reduced by 50%.
4. 3. Requirements for cessation of clearing,
grading, and excavation activities.
a. Inspections and maintenance. Inspections and maintenance of control measures, including BMPs [ , ] associated with clearing, grading, and excavation activities being conducted as part of the exploration and construction phase of a mining operation shall continue until final stabilization has been achieved on all portions of the disturbed area, or until the commencement of the active mining phase for those areas that have been temporarily stabilized as a precursor to mining.
b. Final stabilization. Stabilization measures shall be
initiated immediately in portions of the site where development exploration
or construction activities have permanently ceased, but in no case more
than 14 days after the exploration or construction activity in that
portion of the site has permanently ceased. In arid, semi-arid, and drought-stricken
areas, or in areas subject to snow or freezing conditions, where
initiating perennial vegetative stabilization measures is not possible within
14 days after exploration or construction activity has temporarily or
permanently ceased, final vegetative stabilization measures shall be initiated
as soon as possible. Until final stabilization is achieved temporary
stabilization measures, such as erosion control blankets with an
appropriate seed base and tackifiers, shall be used.
F. Stormwater pollution prevention plan requirements for active, inactive, and temporarily inactive metal mining facilities and sites undergoing reclamation. In addition to the requirements of Part III, the plan shall include, at a minimum, the following items.
1. SWPPP requirements for active, inactive, and temporarily
inactive metal mining facilities, and sites undergoing reclamation.

each area of the mine/mill mine or mill site where stormwater
discharges associated with industrial activities occur, the plan shall identify
the types of pollutants likely to be present in significant amounts (e.g.,
heavy metals, sediment). The following factors shall be considered: the
mineralogy of the ore and waste rock (e.g., acid forming); toxicity and
quantity of chemicals used, produced or discharged; the likelihood, if any,
of contact with stormwater; vegetation of site, if any; and
history of significant leaks/spills leaks and spills of toxic or
hazardous pollutants. A summary of any existing ore or waste rock/overburden
rock and overburden characterization data and test results for potential
generation of acid rock shall also be included. If the ore or waste rock/overburden
rock and overburden characterization data are updated due to a change in
the ore type being mined, the SWPPP shall be updated with the new data.
c. 3. Stormwater controls.
(1) a. Routine facility inspections. Sites
Except for areas subject to clearing, grading, and excavation activities

top box culverts and waterbars; rolling dips and road sloping; roadway surface
water deflector and culverts) or equivalent measures.
(c) Management of runoff. The potential pollutant sources
given in subdivision 1 b of this subsection shall be considered when
determining reasonable and appropriate measures for managing runoff.
(d) (2) Capping. When capping of a contaminant
source is necessary, the source being capped and materials and procedures used
to cap the contaminant source shall be identified.
(e) (3) Treatment. If treatment of a stormwater
discharge is necessary to protect water quality, include a description of the
type and location of stormwater treatment that will be used. Stormwater
treatments include the following: chemical or physical systems; oil/water
oil and water separators; artificial wetlands; etc. The permittee is
encouraged to use both passive and/or and active treatment
of stormwater runoff. Treated runoff may be discharged as a stormwater source
regulated under this permit provided the discharge is not combined with
discharges subject to effluent limitation guidelines for the Ore Mining and
Dressing Point Source Category (40 CFR Part 440 (2007))).
(f) (4) Certification of discharge testing. The
permittee shall test or evaluate all outfalls covered under this permit for the
presence of specific mining-related nonstormwater discharges such as seeps or
adit discharges or discharges subject to effluent limitations guidelines (e.g.,
40 CFR Part 440 (2007))), such as mine drainage or process water.
Alternatively (if applicable), the permittee may certify in the SWPPP that a
particular discharge composed of commingled stormwater and nonstormwater is
covered under a separate VPDES permit; and that permit subjects the
nonstormwater portion to effluent limitations prior to any commingling. This
certification shall identify the nonstormwater discharges, the applicable VPDES
permit(s), the effluent limitations placed on the nonstormwater discharge by
the permit(s), and the points at which the limitations are applied.
2. G. Termination of permit coverage.
a. 1. Termination of permit coverage for sites
reclaimed after December 17, 1990. A site or a portion of a site that has been
released from applicable state or federal reclamation requirements after
December 17, 1990, is no longer required to maintain coverage under this permit,
provided that the covered stormwater discharges do not have the potential to
cause or contribute to violations of state water quality standards. If the
site or portion of a site reclaimed after December 17, 1990, was not subject to
reclamation requirements, the site or portion of the site is no longer required
to maintain coverage under this permit if the site or portion of the site has
been reclaimed as defined in subpart 2 b below subdivision 2 of this
subsection.
b. 2. Termination of permit coverage for sites
reclaimed before December 17, 1990. A site or portion of a site that was
released from applicable state or federal reclamation requirements before
December 17, 1990, or that was otherwise reclaimed before December 17, 1990, is
no longer required to maintain coverage under this permit if the site or
portion of the site has been reclaimed. A site or portion of a site is
considered to have been reclaimed if: (i) stormwater runoff that comes
into contact with (i) raw materials, intermediate byproducts, finished
products, and waste products does not have the potential to cause or contribute
to violations of state water quality standards, (ii) soil-disturbing activities
related to mining at the sites or portion of the site have been completed,
(iii) the site or portion of the site has been stabilized to minimize soil
erosion, and (iv) as appropriate depending on location, size, and the potential
to contribute pollutants to stormwater discharges, the site or portion of the
site has been revegetated, will be amenable to natural revegetation, or will be
left in a condition consistent with the post-mining land use.
H. Inactive and unstaffed sites. Permittees in Sector G seeking to exercise a waiver from the quarterly visual assessment and routine facility inspection requirements for inactive and unstaffed sites (including temporarily inactive sites) are conditionally exempt from the requirement to certify that "there are no industrial materials or activities exposed to stormwater" in Part I A 4.
This exemption is conditioned on the following:
1. If circumstances change and the facility becomes active or staffed, this exception no longer applies and the permittee shall immediately begin complying with the quarterly visual assessment and routine facility inspection requirements; and
2. The board retains the authority to revoke this exemption and the monitoring waiver when it is determined that the discharge causes, has a reasonable potential to cause, or contributes to an instream excursion above an applicable water quality standard, including designated uses.
Subject to the two conditions in subdivisions 1 and 2 of this subsection, if a facility is inactive and unstaffed, the permittee is waived from the requirement to conduct quarterly visual assessments and routine facility inspections. The permittee is not waived from conducting the Part III E comprehensive site inspection. The board encourages the permittee to inspect the site more frequently when there is reason to believe that severe weather or natural disasters may have damaged control measures.
G. I. Benchmark monitoring and reporting
requirements. Note: There are no benchmark monitoring requirements for
inactive and unstaffed sites that have received a waiver in accordance with
Part I A 4 (Inactive and unstaffed sites).
1. Copper ore mining and dressing facilities. Active copper ore mining and dressing facilities are required to monitor their stormwater discharges for the pollutants of concern listed in Table 150-1 below.
2. Discharges from waste rock and overburden piles at active
sites, inactive sites, and sites undergoing reclamation. Discharges from
waste rock and overburden piles at active sites, inactive sites, and sites
undergoing reclamation shall be analyzed for the parameters listed in Table
150-2. Facilities shall also monitor for the parameters listed in Table 150-3.
The director may also notify the facility that additional monitoring must be
performed to accurately characterize the quality and quantity of pollutants
discharged from the waste rock/overburden rock or overburden
piles.

A. Discharges covered under this section. The requirements
listed under this section apply to stormwater discharges associated with
industrial activity from facilities that treat, store, or dispose of hazardous
wastes, including those that are operating under interim status or a permit
under subtitle C of RCRA (Industrial Activity Code "HZ"). Disposal
facilities that have been properly closed and capped, or clean closed,
and have no significant materials exposed to stormwater, are considered
inactive and do not require permits this permit.
B. Special conditions. Prohibition of nonstormwater discharges. In addition to the general prohibition of nonstormwater discharges in Part I B 1, the following discharges are not covered by this permit: leachate, gas collection condensate, drained free liquids, contaminated ground water, laboratory-derived wastewater and contact washwater from washing truck, equipment, and railcar exteriors and surface areas that have come in direct contact with solid waste at the landfill facility.
C. Definitions.
"Contaminated stormwater" means stormwater that comes in direct contact with landfill wastes, the waste handling and treatment areas, or landfill wastewater as defined in this section. Some specific areas of a landfill that may produce contaminated stormwater include, but are not limited to: the open face of an active landfill with exposed waste (no cover added); the areas around wastewater treatment operations; trucks, equipment or machinery that has been in direct contact with the waste; and waste dumping areas.
"Drained free liquids" means aqueous wastes drained from waste containers (e.g., drums, etc.) prior to landfilling.
"Land treatment facility" means a facility or
part of a facility at which hazardous waste is applied onto or incorporated
into the soil surface; such facilities are disposal facilities if the waste
will remain after closure.
"Landfill" means an area of land or an excavation in
which wastes are placed for permanent disposal, that is not a land application
or land treatment unit, surface impoundment, underground injection well, waste
pile, salt dome formation, a salt bed formation, an underground mine or a cave
as these terms are defined in 40 CFR 257.2 (2006), 40 CFR 258.2 (2006)
and 40 CFR 260.10 (2007).
"Landfill wastewater" as defined in 40 CFR Part 445 (2007)
(Landfills Point Source Category) means all wastewater associated with, or
produced by, landfilling activities except for sanitary wastewater,
noncontaminated stormwater, contaminated ground water, and wastewater from
recovery pumping wells. Landfill wastewater includes, but is not limited to,
leachate, gas collection condensate, drained free liquids, laboratory derived
wastewater, contaminated stormwater and contact washwater from washing truck,
equipment, and railcar exteriors and surface areas that have come in direct
contact with solid waste at the landfill facility.
"Leachate" means liquid that has passed through or emerged from solid waste and contains soluble, suspended, or miscible materials removed from such waste.
"Noncontaminated stormwater" means stormwater that
does not come into direct contact with landfill wastes, the waste handling and
treatment areas, or landfill wastewater as defined above. Noncontaminated stormwater
includes stormwater that flows off the cap, cover, intermediate cover, daily
cover, and/or or final cover of the landfill.
"Pile" means any noncontainerized accumulation of
solid, nonflowing hazardous waste that is used for treatment or storage and
that is not a containment building.
"Surface impoundment" means a facility or part of
a facility that is a natural topographic depression, man-made excavation or
diked area formed primarily of earthen materials (although it may be lined with
man-made materials), which is designed to hold an accumulation of liquid wastes
or wastes containing free liquids, and which is not an injection well. Examples
of surface impoundments are holding, storage, settling, and aeration pits,
ponds and lagoons.
D. Numeric effluent limitations. As set forth at 40 CFR Part
445 Subpart A (2007), the numeric limitations in Table 180-1 apply to

the provisions of RCRA Subtitle C at 40 CFR Parts 264 (Subpart N) (2007)
and 265 (Subpart N) (2007) except for any of the following
facilities described in subdivisions 1 through 4 of this subsection:
1. Landfills operated in conjunction with other industrial or commercial operations when the landfill only receives wastes generated by the industrial or commercial operation directly associated with the landfill;
2. Landfills operated in conjunction with other industrial or
commercial operations when the landfill receives wastes generated by the
industrial or commercial operation directly associated with the landfill and
also receives other wastes provided the other wastes received for disposal are
generated by a facility that is subject to the same provisions in 40 CFR
Subchapter N (2007) as the industrial or commercial operation or the
other wastes received are of similar nature to the wastes generated by the
industrial or commercial operation;
3. Landfills operated in conjunction with Centralized Waste
Treatment (CWT) facilities subject to 40 CFR Part 437 (2007) so long as
the CWT facility commingles the landfill wastewater with other nonlandfill
wastewater for discharge. A landfill directly associated with a CWT facility is
subject to this part if the CWT facility discharges landfill wastewater
separately from other CWT wastewater or commingles the wastewater from its
landfill only with wastewater from other landfills; or
4. Landfills operated in conjunction with other industrial or commercial operations when the landfill receives wastes from public service activities so long as the company owning the landfill does not receive a fee or other remuneration for the disposal service.

biochemical decomposition (be aware of attracting wildlife that may prove
hazardous to flight operations); and directing runoff into vegetative swales or
other infiltration measures. The plan shall consider the recovery of deicing/anti-icing
deicing and anti-icing materials when these materials are applied during
nonprecipitation events (e.g., covering storm sewer inlets, using booms,
installing absorptive interceptors in the drains, etc.) to prevent these
materials from later becoming a source of stormwater contamination. Used
deicing fluid shall be recycled whenever possible.
d. Routine facility inspections. The inspection frequency
shall be specified in the plan. At a minimum, inspections shall be conducted
once per month during deicing/anti-icing deicing and anti-icing

before or after this period, the inspections shall be expanded to include all
months during which deicing chemicals may be used. Also, if significantly or
deleteriously large quantities of deicing chemicals are being spilled or
discharged, or if water quality impacts have been reported, the inspection
frequency shall be increased to weekly until such time as the chemical
spills/discharges or impacts are reduced to acceptable levels. The director may
specifically require increased inspections and the SWPPP to be reevaluated as
necessary.
[ e. Comprehensive site compliance evaluation. The annual site compliance evaluations shall be conducted by qualified facility personnel during periods of actual deicing operations, if possible. If not practicable during active deicing or if the weather is too inclement, the evaluations shall be conducted when deicing operations are likely to occur and the materials and equipment for deicing are in place. ]
