The immediacy and accuracy of the Continuous Emission Monitoring System (CEMS) for stationary sources of air pollutants is far superior to the data from regular inspections. Since 1975, countries have successively applied it to the monitoring and control of air pollutant emissions from large stationary pollution sources. In recent years, it has been further used as a tool for emissions trading, and after the implementation of data disclosure, it can also be used as a tool for national supervision.
Since the CEMS fraud occurred in 2000, the Environmental Protection Agency has continued to review and revise the CEMS management regulations. In addition to revising relevant norms in line with technological development, it has also strengthened CEMS fraud prevention measures in response to the fraud.
The primary tasks in this year include:
(1) Assist in reviewing and evaluating the CEMS monitoring facility of stationary source and data acquisition and handling system (DAHS) verification regulatory specifications, develop relevant supporting management measures, improve the quality of data control, and improve the CEMS management system. (2) In order to improve air pollution control measures, assist in the development of control specifications for continuous automatic monitoring facilities for operating parameters of stationary sources (Continuous parameters monitoring system, CPMS), so as to urge public and private places to implement the normal operation of pollution control equipment and reduce air pollutant emissions. (3) Assist in reviewing the air pollution control regulations of the optoelectronic industry and semiconductor industry, strengthen the improvement of pollution sources, and achieve the goal of air pollution reduction. (4) In order to improve the CEMS management and auditing capabilities of local environmental protection bureaus, assist in the handling of CEMS auditing and counseling, and evaluate the effectiveness of CEMS control by local environmental protection bureaus, so as to improve the effectiveness of CEMS implementation and control across the country. (5) Cooperate with the CEMS management regulation to amend and add the fifth batch of control objects, expand system functions and maintain the stable operation of each system, and improve the management performance of information inspection.
After the revision and release of the second stage of CEMS management regulations, the public and private places should comply with the regulations from October 1, 2021 onwards. However, due to the impact of the COVID-19 epidemic, the period has been extended to 2022. Therefore, it is still in the transition period to the completion stage in this year, so focus on the public and private places that have completed the confirmation process, and carry out a total of 5 stacks audit for batches 1 to 5 to confirm the implementation status of the regulations. For the public and private places that have not been replaced the CEMS for the new CEMS regulations, the counseling setup and connection operations will be strengthened, and through the implementation process, the actual control issues after the implementation of the laws and regulations will be collected and fed back to the content of the next stage of law revision. In addition, in order to enable the successful implementation of the data acquisition and processing system (DAHS) verification agency certification standards in 2025, we continued the work of last year, carried out 2 factory verification simulations, and proposed a draft of agency management and verification points based on the administrative entrusted control structure. In order to improve air pollution control measures, we continue to study and analyses the specifications of Continuous Parameter Monitoring System (CPMS) for operating parameters, understand the key parameters and monitoring locations, and evaluate the feasibility of the application of digital inspection tools. In addition, we continue to review the emission standards and specifications of the optoelectronic and semiconductor industries, cooperate with the implementation of 4 field surveys, provide pollution emission improvement suggestions, and revise the overall specifications in a timely manner. In addition, by investigating the implementation status of CEMS management of 18 local environmental protection bureaus, evaluating the effectiveness of CEMS control of local environmental protection bureaus, and strengthening the explanation of the key points of the implementation of laws and regulations, in order to facilitate the bureaus to assist public and private places to complete CEMS setup, replacement and connection operations as soon as possible.At the same time, we strengthen the CEMS information system tools at the central office of the local environmental protection bureaus, expands the functions of CEMS data analysis and inspection management, and helps the central office save manpower and time to meet the second-stage management regulations.
