GWPB 4-1999 Synthetic Ammonia Industry Water Pollutant Discharge Standard
The General Water Pollution Prevention and Control Board (GWPB) 4-1999 Synthetic Ammonia Industry Water Pollutant Discharge Standards is intended to address pollutants discharged from the synthetic ammonia industry, including ponds, cooling towers, wastewater systems, and evaporators. This standard imposes certain levels of water pollutant discharge that should be adhered to in order for businesses to reduce their impact on the surrounding environment.
The GWPB 4-1999 standard is characterized by its emphasis on the minimization of water pollutant discharge from the synthetic ammonia industry. The standard requires businesses to adhere to specific pollutant loads, limits, and concentrations for the entire range of pollutants. This includes total dissolved solids, ammonia nitrogen, total suspended solids, oil and grease, and Ethylenediaminetetraacetic acid (EDTA), and other hazardous substances.
Synthetic ammonia manufacturers must also adhere to regulation requirements in terms of the control of volatile organic compound (VOC) emissions. This includes the control of emissions of any compounds that are known to possess ozone-depleting or ozone-forming properties. Under this section, businesses must adhere to specific emission limits that are prescribed based on the size of the installation and the quantity of the VOCs emitted.
The standard also includes specific requirements for wastewater discharge. It requires businesses to adhere to specific wastewater discharge parameters, including pH, Total Suspended Solids (TSS), and specific pollutants exceeding identified standards such as Total Kjeldahl Nitrogen (TKN), Total Phosphorus (TP), Anaerobic Biodegradability, Oxygen Demand (BOD) and so on. Businesses must also monitor the levels of these pollutants at certain intervals and take prompt action on any identified exceeding levels.
In addition to this, the GWPB 4-1999 standard requires businesses to undertake certain corrective measures in order to ensure the effective control of water pollutant discharge. This includes the maintenance of wastewater treatment systems, the installation of wastewater treatment systems, the enforcement of operational parameters and other technological solutions to ensure that the allowable pollutant discharges are not exceeded.
Finally, the standard also imposes certain reporting requirements on businesses. Businesses are required to submit discharge continuous records every three months to the synthetic ammonia industry in order to monitor their performance. Records should be clearly labeled with the corresponding parameters, time-stamped and signed off by the employee in charge of the operations. It should ultimately be provided to the GWPB within a specified time frame.
In summation, the GWPB 4-1999 Synthetic Ammonia Industry Water Pollutant Discharge Standard is intended to reduce water pollutant discharge from the synthetic ammonia industry. It encourages businesses in this industry to adhere to certain pollutant concentration levels and also to submit periodic reports to the relevant authorities in order to ensure compliance with the standard. It is clear that the GWPB 4-1999 standard is a crucial component of the synthetic ammonia production industry and its implementation is essential for minimizing water pollutant discharge.
