GB/T 13201--91 Technical Method for Establishing Local Atmospheric Pollutant Emission Standards
This paper focuses on the technical method formulated in the standard of GB/T 13201--91, designed to establish local atmospheric pollutant emission standards. This standard specifies the steps and procedures of estimating the emission of local atmospheric pollutants and formulating emission standards based on the estimated emission.
When assessing the atmospheric pollutant emission standard of a certain region, there are three main steps. The first step is to determine the total emission of local atmospheric pollutants on the basis of actual surveys and measurements, and analyze the sources and effects of such emissions. The second step is to formulate emission standards based on the estimated amount of atmospheric emissions; the standards should take into account the regional environmental protection goals, the existing regional emission levels and the potential further reduction of emissions, as well as the potential environmental benefits. The third step is to monitor the regions atmospheric pollutant emissions, compare them with the set emission standards, and take corrective measures if the set standards are not being met.
In order to facilitate the implementation of this standard, the following research and analysis should be done in each step.
In the first step, its important to conduct surveys and measurements to assess the sources of atmospheric pollutants entering the region, the levels of atmospheric concentration, the total amount of emissions, and their impacts. Air quality monitoring, atmospheric discharge sources inventory and external emission estimation should be conducted.
In the second step, emission standards should be formulated based on the estimated emissions from the first step. It is necessary to consider the existing total emission amount and its sources, the emission change dynamics, and the potential environmental benefits of emission reductions when deciding on emission limits. It is also important to consider economic factors and life cycles of economic activities when setting emission standards.
In the third step, it is important to monitor the actual emission levels of various atmospheric pollutants in the region by means of both continuous monitoring and spot checks. Its necessary to assess the achievability of set emission standards and take corrective measures if the standards are not met. Punitive measures should also be taken to punish those who fail to comply with the emission standards.
GB/T 13201-91 is a comprehensive technical method that can help local governments establish their atmospheric pollutant emission standards more effectively. Through approaching the assessment of local atmospheric emissions in a methodical step-by-step manner, a scientific and accurate assessment can be made and appropriate emission standards can be formulated for each region. By adhering to such emission standards, the environmental quality of local areas will be pushed up and improved.
