The State Water Control Board amended and reissued the Virginia Pollutant Discharge Elimination System general permit for potable water treatment plants to discharge process wastewater. The amendments update definitions, add total suspended solids and chlorine discharge limits for reverse osmosis and nanofiltration plants, and include electronic reporting requirements. See http://register.dls.virginia.gov/vol39/iss11/v39i11.pdf (pp. 1355-68).
