If contacted by the department regarding an incomplete reimbursement application, an applicant will have 14 days from the date of the call or letter to submit the information requested and correct any deficiencies. Extensions of the 14-day deadline will not be granted. An application that does not contain all of the required information after the 14-day time frame may be rejected.

2. Only invoices pertaining to the monitoring activity claimed in the current application will be accepted. Costs omitted from previous claims are ineligible for reimbursement in subsequent claims. Invoices submitted in previous claims are not eligible documentation for reimbursement of costs in subsequent claims. To reduce the risk of disqualification of costs, costs for different monitoring activities should be invoiced separately. If possible, invoices should be structured so that costs are grouped according to task or activity.

E. Reconsideration process.

1. Claimants may submit a written response indicating why they believe costs denied on the reimbursement decision should be paid.

2. If the claimant disagrees with the decision in the reimbursement payment package, a notice of intent (NOI) to object and a reconsideration claim form must be submitted to the department within the filing deadlines specified in the reconsideration procedure package:

a. If filing deadlines are not met, the decision in the reimbursement payment package is final. This written objection shall be in the format specified in the reconsideration procedure package and explain the reasons for disagreement with the decisions in the reimbursement payment letter and supply any additional supporting documentation.

b. Upon receipt of this information and at the claimant's request, the department may schedule a reconsideration meeting to reevaluate the denied costs.

3. Claimants will be given an opportunity to contest the reimbursement decisions in accordance with the Administrative Process Act (§ 2.2-4000 et seq. of the Code of Virginia). Within the filing deadline, the claimant must submit a written summary of the issues that will be contested using the reconsideration claim form.

4. The reconsideration procedures provide the department the opportunity to correct certain errors as follows:

a. Failure of the reviewer to verify an invoice form that was received prior to completing the verification package for the reimbursement.

b. Errors the reviewer makes in verifying an invoice form.

c. Failure of the claimant to submit all invoices.

5. Errors ineligible for reconsideration. Notwithstanding the above, some types of errors cannot be corrected using the reconsideration process. It is the responsibility of the claimant or consultant, or both, to ensure that all application forms (invoice forms, and sampling and testing verification) are complete and accurate. The following types of errors may result in a denial of costs:

a. Items omitted from the invoice;

b. Unverified sampling and testing results;

c. Additions or revisions to the invoice forms submitted after the reviewer forwards the verification package to the department;

d. Using one invoice in multiple claims. Invoices submitted in an application cannot be used as documentation for reimbursement of costs in subsequent claims;

e. Failure to claim performed work on the invoice form;

f. Failure to claim sampling and testing costs as authorized; or

g. Failure to obtain prior approval from the department for costs that exceed $2.50 per dry ton of biosolids or industrial residuals land applied.

"Total solids" means the materials in sewage sludge that remain as residue when the sewage sludge is dried to 103°C to 105°C.

"Toxic pollutant" means any pollutant listed as toxic under § 307 (a)(1) of the CWA or, in the case of "sludge use or disposal practices," any pollutant identified in regulations implementing § 405 (d) of the CWA.

"Toxicity" means the inherent potential or capacity of a material to cause adverse effects in a living organism, including acute or chronic effects to aquatic life, detrimental effects on human health, or other adverse environmental effects.

"Treatment facility" means only those mechanical power driven devices necessary for the transmission and treatment of pollutants (e.g., pump stations, unit treatment processes).

"Treat sewage sludge" or "treatment of sewage sludge" means the preparation of sewage sludge for final use or disposal. This includes, but is not limited to, thickening, stabilization, and dewatering of sewage sludge. This does not include storage of sewage sludge.

"Vegetated buffer" means a permanent strip of dense perennial vegetation established parallel to the contours of and perpendicular to the dominant slope of the field for the purposes of slowing water runoff, enhancing water infiltration, and minimizing the risk of any potential nutrients or pollutants from leaving the field and reaching surface waters.

"Virginia Pollution Abatement (VPA) permit" means a document issued by the board, pursuant to this chapter, authorizing pollutant management activities under prescribed conditions.

"Virginia Pollutant Discharge Elimination System (VPDES) permit" means a document issued by the board pursuant to 9VAC25-31-10 et seq., authorizing, under prescribed conditions, the potential or actual discharge of pollutants from a point source to surface waters.

"Volatile solids" means the amount of the total solids in sewage sludge lost when the sewage sludge is combusted at 550°C in the presence of excess air.

"VPA application" means the standard form or forms approved by the board for applying for a VPA permit.

"Water quality standards" means the narrative statements for general requirements and numeric limits for specific requirements that describe the water quality necessary to meet and maintain reasonable and beneficial uses. Such standards are established by the board under § 62.1-44.15 (3a) of the Code of Virginia.

B. Generally used technical terms not defined in subsection A of this section or the department's latest definitions of technical terms as used to implement § 62.1-44.15 of the Code of Virginia shall be defined in accordance with "Glossary-Water and Wastewater Control Engineering" published by the American Public Health Association (APHA), American Society of Civil Engineers (ASCE), American Water Works Association (AWWA), and the Water Environment Federation (WEF).

9VAC25-32-285. Local enforcement.

A. In the event of a dispute concerning the existence of a violation between a permittee and a locality that has adopted a local ordinance for testing and monitoring of the land application of biosolids or industrial residuals, the activity alleged to be in violation shall be halted pending a determination by the director.

B. Upon determination by the director that there has been a violation of § 62.1-44.16, 62.1-44.19:3, 62.1-44.19:3.1, or 62.1-44.19:3.3 of the Code of Virginia; of any regulation promulgated under those sections; or of any permit or certificate issued for land application of industrial residuals, and that such violation poses an imminent threat to public health, safety, or welfare, the department shall commence appropriate action to abate the violation and immediately notify the chief administrative officer of any locality potentially affected by the violation.

C. Local governments shall promptly notify the department of all results from the testing and monitoring of the land application of biosolids or industrial residuals performed by persons employed by local governments and any violation of § 62.1-44.16, 62.1-44.19:3, 62.1-44.19:3.1, or 62.1-44.19:3.3 of the Code of Virginia or any permit or certificate issued for land application of industrial residuals discovered by local governments.
