Virginia Administrative Code
Title 9. Environment
Agency 25. State Water Control Board
Chapter 870. Virginia Stormwater Management Program (VSMP) Regulation

9VAC25-870-310. Prohibitions.

A. Except in compliance with a state permit issued by the department pursuant to the Virginia Stormwater Management Act, it shall be unlawful for any person to discharge stormwater into state waters from Municipal Separate Storm Sewer Systems or land-disturbing activities.

B. Any person in violation of subsection A of this section, who discharges or causes or allows a discharge of stormwater into or upon state waters from Municipal Separate Storm Sewer Systems or land-disturbing activities, or who discharges or causes or allows a discharge that may reasonably be expected to enter state waters in violation of subsection A of this section, shall notify the department of the discharge immediately upon discovery of the discharge but in no case later than 24 hours after said discovery. A written report of the unauthorized discharge shall be submitted by the owner, to the department, within five days of discovery of the discharge. The written report shall contain:

1. A description of the nature and location of the discharge;

2. The cause of the discharge;

3. The date on which the discharge occurred;

4. The length of time that the discharge continued;

5. The volume of the discharge;

6. If the discharge is continuing, how long it is expected to continue;

7. If the discharge is continuing, what the expected total volume of the discharge will be; and

8. Any steps planned or taken to reduce, eliminate, and prevent a recurrence of the present discharge or any future discharges not authorized by the state permit.

C. No state permit may be issued:

1. When the conditions of the state permit do not provide for compliance with the applicable requirements of the CWA or the Act, or regulations promulgated under the CWA or the Act;

2. When the state permit applicant is required to obtain a state or other appropriate certification under § 401 of the CWA and that certification has not been obtained or waived;

3. When the regional administrator has objected to issuance of the state permit;

4. When the imposition of conditions cannot ensure compliance with the applicable water quality requirements of all affected states;

5. When, in the judgment of the Secretary of the Army, anchorage and navigation in or on any of the waters of the United States would be substantially impaired by the discharge;

6. For the discharge of any radiological, chemical, or biological warfare agent or high-level radioactive waste;

7. For any discharge inconsistent with a plan or plan amendment approved under § 208(b) of the CWA;

8. For any discharge to the territorial sea, the waters of the contiguous zone, or the oceans in the following circumstances:

a. Before the promulgation of guidelines under § 403(c) of the CWA (for determining degradation of the waters of the territorial seas, the contiguous zone, and the oceans) unless the department determines state permit issuance to be in the public interest; or

b. After promulgation of guidelines under § 403(c) of the CWA, when insufficient information exists to make a reasonable judgment whether the discharge complies with them.

9. To a new source or a new discharger, if the discharge from its construction or operation will cause or contribute to the violation of water quality standards. The owner or operator of a new source or new discharger proposing to discharge into a water segment which does not meet applicable water quality standards or is not expected to meet those standards even after the application of the effluent limitations required by the Act and §§ 301(b)(1)(A) and 301(b)(1)(B) of the CWA, and for which the department has performed a pollutants load allocation for the pollutant to be discharged, must demonstrate, before the close of the public comment period, that:

a. There are sufficient remaining pollutant load allocations to allow for the discharge; and

b. The existing dischargers into that segment are subject to compliance schedules designed to bring the segment into compliance with applicable water quality standards. The department may waive the submission of information by the new source or new discharger required by this subdivision if the department determines that it already has adequate information to evaluate the request. An explanation of the development of limitations to meet the criteria of this paragraph is to be included in the fact sheet to the state permit under 9VAC25-870-520.
