Assuming minimum dilution 1:10 in discharge, lower ratio would attract progressively stringent standards to be determined by the Federal Environmental Protection Agency. By 1:10 dilution 2. Methylene Blue Active Substances; assuming surfactant as biodegradable 3. Pesticides include herbicides, fungicides and insecticides. 4. Subject to total toxic metals discharge should not exceed level given at S.No.25. 5. Applicable only when and where sewage treatment is operational and BOD5=80mg/l is achieved by the sewage treatment system. 6. Provided discharge is not at shore and not within 10 miles of mangrove or other important estuaries. * The effluent should not result in temperature increase of more than 3 0C at the edge of the zone where initial mixing and dilution take place in the receiving body. In case zone is not defined, use 100 meters from the discharge. ** The value for industry is 200 mg/l *** Discharge concentration at or below sea concentration (SC).
