The State Water Control Board amended and reissued the existing Virginia Pollutant Discharge Elimination System general permit regulation for noncontact cooling water discharges of 50,000 gallons per day or less. The revisions adjust effluent limits, including making chlorine non-detectable limit compatible with EPA reporting requirements; clarify definitions; adjust water quality standards; and conform to statutory changes. See http://register.dls.virginia.gov/vol39/iss11/v39i11.pdf (pp. 1343-55).
