9VAC25-210-110. Establishing applicable standards, limitations, or other VWP permit conditions.
A. In addition to the conditions established in 9VAC25-210-90 and 9VAC25-210-100, and for surface water withdrawals in 9VAC25-210-370, each VWP permit shall include conditions meeting the requirements established in this section where applicable.
B. Water quality standards and state requirements. The VWP permit shall include requirements to comply with all appropriate provisions of state laws and regulations.
C. Toxic pollutants.
1. Where the board finds that appropriate limitations may not ensure compliance with the law or state water quality standards the board shall require the permittee to follow a program of biological or chemical toxics monitoring. The requirement may include a VWP permit reopener to allow the imposition of toxicity reduction or elimination measures determined to be necessary as a result of the board's evaluation of the results of the toxic monitoring and other available information. Based upon this determination, appropriate limitations will be included in the VWP permit to ensure the reduction or elimination of toxic pollutants and allow the board to ensure that the proposed project will comply with water quality standards and other appropriate requirements of the law.
2. Limitations will be included in the VWP permit to control all toxic pollutants which the board determines (based on information reported in a VWP permit application or a notification or on other information) are or may be discharged at a level which would adversely affect the beneficial use of the receiving waters.
D. Monitoring requirements as conditions of VWP permits may include but are not limited to:
1. Requirements concerning the proper use, maintenance and installation, when appropriate, of monitoring equipment or methods (including biological monitoring methods when appropriate) when required as a condition of the VWP permit;
2. Required monitoring including type, intervals, and frequency sufficient to yield data which are representative of the monitored activity and including, when appropriate, continuous monitoring and composite samples;
3. Applicable reporting requirements based upon the impact of the regulated activity on water quality; and
4. Requirements to report monitoring results with a frequency dependent on the nature and effect of the regulated activity.
E. Best management practices (BMPs). The VWP permit may require the use of BMPs to control or abate the discharge of pollutants.
F. Reissued VWP permits. When a VWP permit is renewed or reissued, limitations, standards, or conditions must be in conformance with current limitations, standards, or conditions.
G. Reopening VWP permits. Each VWP permit shall have a condition allowing the reopening of the VWP permit for the purpose of modifying the conditions of the VWP permit to meet new regulatory standards duly adopted by the board. Cause for reopening VWP permits includes, but is not limited to when the circumstances on which the previous VWP permit was based have materially and substantially changed, or special studies conducted by the board or the permittee show material and substantial change, since the time the VWP permit was issued and thereby constitute cause for VWP permit modification or revocation and reissuance.
