The control authority may determine that an industrial user subject to categorical pretreatment standards under 9VAC25-31-780 and 40 CFR chapter I, subchapter N is a nonsignificant categorical industrial user rather than a significant industrial user on a finding that the industrial user never discharges more than 100 gallons per day (gpd) of total categorical wastewater (excluding sanitary, noncontact cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard) and the following conditions are met:

a. The industrial user, prior to control authority's finding, has consistently complied with all applicable categorical pretreatment standards and requirements;

b. The industrial user annually submits the certification statement required in 9VAC25-31-840 together with any additional information necessary to support the certification statement; and

c. The industrial user never discharges any untreated concentrated wastewater.

3. Upon a finding that an industrial user meeting the criteria in subdivision 1 b of this definition has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the control authority may at any time, on its own initiative or in response to a petition received from an industrial user or POTW, and in accordance with Part VII (9VAC25-31-730 et seq.) of this chapter, determine that such industrial user is not a significant industrial user.

B. Publicly and privately owned treatment works. All POTWs and PVOTWs must provide adequate notice to the department of the following:

1. Any new introduction of pollutants into the POTW or PVOTW from an indirect discharger which would be subject to § 301 or 306 of the CWA and the law if it were directly discharging those pollutants; and

2. Any substantial change in the volume or character of pollutants being introduced into that POTW or PVOTW by a source introducing pollutants into the POTW or PVOTW at the time of issuance of the permit.

3. For purposes of this subsection, adequate notice shall include information on (i) the quality and quantity of effluent introduced into the POTW or PVOTW, and (ii) any anticipated impact of the change on the quantity or quality of effluent to be discharged from the POTW or PVOTW.

4. When the monthly average flow influent to a POTW or PVOTW reaches 95% of the design capacity authorized by the VPDES permit for each month of any three-month period, the owner shall within 30 days notify the department in writing and within 90 days submit a plan of action for ensuring continued compliance with the terms of the permit.

a. The plan shall include the necessary steps and a prompt schedule of implementation for controlling any current problem, or any problem which could be reasonably anticipated, resulting from high influent flows.

b. Upon receipt of the owner's plan of action, the board shall notify the owner whether the plan is approved or disapproved. If the plan is disapproved, such notification shall state the reasons and specify the actions necessary to obtain approval of the plan.

3. Requirements relating to transfer of manure or process wastewater to other persons. Prior to transferring manure, litter or process wastewater to other persons, large CAFOs must provide the recipient of the manure, litter or process wastewater with the most current nutrient analysis. The analysis provided must be consistent with the requirements of EPA Effluent Guidelines for Feedlots (40 CFR Part 412). Large CAFOs must retain for five years records of the date, recipient name and address and approximate amount of manure, litter or process wastewater transferred to another person.

4. Annual reporting requirements for CAFOs. The permittee must submit an annual report to the director. The annual report must include:

a. The number and type of animals, whether in open confinement or housed under roof (beef cattle, broilers, layers, swine weighing 55 pounds or more, swine weighing less than 55 pounds, mature dairy cows, dairy heifers, veal calves, sheep and lambs, horses, ducks, turkeys, other);

b. Estimated amount of total manure, litter and process wastewater generated by the CAFO in the previous 12 months (tons/gallons);

c. Estimated amount of total manure, litter and process wastewater transferred to other persons by the CAFO in the previous 12 months (tons/gallons);

d. Total number of acres for land application covered by the nutrient management plan developed in accordance with subdivision 1 of this subsection;

f. Summary of all manure, litter and process wastewater discharges from the production area that occurred in the previous 12 months including date, time and approximate volume;

g. A statement indicating whether the current version of the CAFO's nutrient management plan was developed or approved by a certified nutrient management planner; and

h. The actual crop(s) planted and actual yield(s) for each field, the actual nitrogen and phosphorus content of the manure, litter, and process wastewater, the results of calculations conducted in accordance with subdivisions 5 a (2) and 5 b (4) of this subsection, and the amount of manure, litter, and process wastewater applied to each field during the previous 12 months; and, for any CAFO that implements a nutrient management plan that addresses rates of application in accordance with subdivision 5 b of this subsection, the results of any soil testing for nitrogen and phosphorus taken during the preceding 12 months, the data used in calculations conducted in accordance with subdivision 5 b (4) of this subsection, and the amount of any supplemental fertilizer applied during the previous 12 months.

5. Terms of the nutrient management plan. Any permit issued to a CAFO shall require compliance with the terms of the CAFO's site-specific nutrient management plan. The terms of the nutrient management plan are the information, protocols, best management practices, and other conditions in the nutrient management plan determined by the board to be necessary to meet the requirements of subdivision 1 of this subsection. The terms of the nutrient management plan, with respect to protocols for land application of manure, litter, or process wastewater required by subdivision 4 h of this subsection and, as applicable, 40 CFR 412.4(c), shall include the fields available for land application; field-specific rates of application properly developed, as specified in subdivisions 5 a and b of this subsection, to ensure appropriate agricultural utilization of the nutrients in the manure, litter, or process wastewater; and any timing limitations identified in the nutrient management plan concerning land application on the fields available for land application. The terms shall address rates of application using one of the following two approaches, unless the board specifies that only one of these approaches may be used:

a. Linear approach. An approach that expresses rates of application as pounds of nitrogen and phosphorus, according to the following specifications:

(1) The terms include maximum application rates from manure, litter, and process wastewater for each year of permit coverage, for each crop identified in the nutrient management plan, in chemical forms determined to be acceptable to the board, in pounds per acre, per year, for each field to be used for land application, and certain factors necessary to determine such rates. At a minimum, the factors that are terms shall include: the outcome of the field-specific assessment of the potential for nitrogen and phosphorus transport from each field; the crops to be planted in each field or any other uses of a field such as pasture or fallow fields; the realistic yield goal for each crop or use identified for each field; the nitrogen and phosphorus recommendations from sources specified by the board for each crop or use identified for each field; credits for all nitrogen in the field that will be plant available; consideration of multi-year phosphorus application; and accounting for all other additions of plant available nitrogen and phosphorus to the field. In addition, the terms include the form and source of manure, litter, and process wastewater to be land-applied; the timing and method of land application; and the methodology by which the nutrient management plan accounts for the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied.

(2) Large CAFOs that use this approach shall calculate the maximum amount of manure, litter, and process wastewater to be land applied at least once each year using the results of the most recent representative manure, litter, and process wastewater tests for nitrogen and phosphorus taken within 12 months of the date of land application; or

b. Narrative rate approach. An approach that expresses rates of application as a narrative rate of application that results in the amount, in tons or gallons, of manure, litter, and process wastewater to be land applied, according to the following specifications:

(1) The terms include maximum amounts of nitrogen and phosphorus derived from all sources of nutrients, for each crop identified in the nutrient management plan, in chemical forms determined to be acceptable to the board, in pounds per acre, for each field, and certain factors necessary to determine such amounts. At a minimum, the factors that are terms shall include: the outcome of the field-specific assessment of the potential for nitrogen and phosphorus transport from each field; the crops to be planted in each field or any other uses such as pasture or fallow fields (including alternative crops identified in accordance with subdivision 5 b (2) of this subsection); the realistic yield goal for each crop or use identified for each field; and the nitrogen and phosphorus recommendations from sources specified by the board for each crop or use identified for each field. In addition, the terms include the methodology by which the nutrient management plan accounts for the following factors when calculating the amounts of manure, litter, and process wastewater to be land applied: results of soil tests conducted in accordance with protocols identified in the nutrient management plan, as required by subdivision 1 g of this subsection; credits for all nitrogen in the field that will be plant available; the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied; consideration of multi-year phosphorus application; accounting for all other additions of plant available nitrogen and phosphorus to the field; the form and source of manure, litter, and process wastewater; the timing and method of land application; and volatilization of nitrogen and mineralization of organic nitrogen.

(2) The terms of the nutrient management plan include alternative crops identified in the CAFO's nutrient management plan that are not in the planned crop rotation. Where a CAFO includes alternative crops in its nutrient management plan, the crops shall be listed by field, in addition to the crops identified in the planned crop rotation for that field, and the nutrient management plan shall include realistic crop yield goals and the nitrogen and phosphorus recommendations from sources specified by the board for each crop. Maximum amounts of nitrogen and phosphorus from all sources of nutrients and the amounts of manure, litter, and process wastewater to be applied shall be determined in accordance with the methodology described in subdivision 5 b (1) of this subsection.

(3) For CAFOs using this approach, the following projections shall be included in the nutrient management plan submitted to the board, but are not terms of the nutrient management plan: the CAFO's planned crop rotations for each field for the period of permit coverage; the projected amount of manure, litter, or process wastewater to be applied; projected credits for all nitrogen in the field that will be plant available; consideration of multi-year phosphorus application; accounting for all other additions of plant available nitrogen and phosphorus to the field; and the predicted form, source, and method of application of manure, litter, and process wastewater for each crop. Timing of application for each field, insofar as it concerns the calculation of rates of application, is not a term of the nutrient management plan.

(4) CAFOs that use this approach shall calculate maximum amounts of manure, litter, and process wastewater to be land applied at least once each year using the methodology required in subdivision 5 b (1) of this subsection before land applying manure, litter, and process wastewater and shall rely on the following data:

(a) A field-specific determination of soil levels of nitrogen and phosphorus, including, for nitrogen, a concurrent determination of nitrogen that will be plant available consistent with the methodology required by subdivision 5 b (1) of this subsection, and for phosphorus, the results of the most recent soil test conducted in accordance with soil testing requirements approved by the board; and

(b) The results of most recent representative manure, litter, and process wastewater tests for nitrogen and phosphorus taken within 12 months of the date of land application, in order to determine the amount of nitrogen and phosphorus in the manure, litter, and process wastewater to be applied.
