GB 13456-92 Steel Industry Water Pollution Emission Standards
In order to protect the environment, the State Council ratified the Steel Industry Water Pollution Emission Standard (GB 13456-92) on April 1, 1993, which became effective on July 1 of that same year. This standard applies to all types of steel plants, including both sintering and milling operations.
The standard makes clear that it is the responsibility of every steel plant to implement measures to control and reduce water pollution. It is particularly strict in limiting how much of potentially hazardous substances can be discharged into surrounding water sources.
As part of this standard, the factory must report emissions of certain substances and take part in semi-annual or annual emissions testing. The standard also sets limits for emissions of substances such as chromium, zinc, cadmium, arsenic and lead.
The standard also sets out requirements for monitoring and recognizing the potential water pollution level of every steel plant. It specifies the testing procedures and reporting requirements for the factory.
The standard also sets limits on allowable levels of substances in sludge, wastewater and air emissions. Quality assurance plans must also be implemented by the steel plant for wastewater. These provisions are in place to safeguard the state of the plants surroundings and to ensure that the plant is operating in an environmentally responsible manner.
In accordance with the Steel Industry Water Pollution Emission Standard, all plants must undergo assessment and examination by a qualified team appointed by the State Environmental Protection Administration. This team will help to ensure that the plant is in compliance with the standard’s requirements.
In addition, the standard sets out regulations and requirements for the release of wastewater and solid waste associated with steel production. Such releases must be within safe and appropriate limits in order to safeguard the wellbeing of the environment and the nearby population.
The standard also applies to the sewage treatment process at steel plants, providing requirements for types of treatment, biocommunity assessment, and reuse of sewage water. Overall, this standard provides steel factories with the framework necessary to protect their environment and the world around them.
