Assuming minimum dilution 1:10 on discharge, lower ratio would attract progressively stringent standards to be determined by the Federal Environmental Protection Agency. By 1:10 dilution means, for example that for each one cubic meter of treated effluent, the recipient water body should have 10 cubic meter of water for dilution of this effluent. 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. N. 25. 5. Applicable only when and where sewage treatment is operational and BOD5=80mg/I is achieved by the sewage treatment system. PART-II] THE GAZETTE OF PAKISTAN, EXTRA, AUGUST 10, 2000 1292 =============================================================== 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 30C 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 point of discharge. ** The value for industry is 200 mg/I *** Discharge concentration at or below sea concentration (SC). Note: 1. Dilution of liquid effluents to bring them to the NEQS limiting values is not permissible through fresh water mixing with the effluent before discharging into the environment. 2. The concentration of pollutants in water being used will be substracted from the effluent for calculating the NEQS limits” and (2) for Annex-II the following shall be substituted, namely: Annex-II “NATIONAL ENVIRONMENTAL QUALITY STANDARDS FOR INDUSTRIAL GASEOUS EMISSION (mg/Nm3, UNLESS OTHERWISE DEFINED).” S.

Based on the assumption that the size of the particulate is 10 micron or more. 2. Based on 1 percent Sulphur content in fuel oil. Higher content of Sulphur will case standards to be pro-rated. 3. In respect of emissions of Sulphur dioxide and Nitrogen oxides, the power plants operating on oil and coal as fuel shall in addition to National Environmental Quality Standards (NEQS) specified above, comply with the following standards: 1294 THE GAZETTE OF PAKISTAN, EXTRA, AUGUST 10, 2000 PART-II] =============================================================== A.
