The petrochemical industry self-monitoring technical guide issued

Recently, the Ministry of Ecological Environment issued the "Technical Guide for Self-Monitoring of Sewage Units" (hereinafter referred to as the "Guidelines"). Compared with the draft for comments issued in October 2017, the Guidelines include a minimum frequency for monitoring the exhaust cylinders of hazardous waste incinerators, with major pollutants including nitrogen oxides, hydrogen fluoride, dioxins, etc.; At the same time, the monitoring index of the quality impact of the surrounding environment has been improved, and the minimum frequency of monitoring of surface water, groundwater, sea water and soil has been increased.the relevant person in charge of the
standard preparation group said that the monitoring frequency is the core content of the monitoring program, and the existing standard specifications on the monitoring frequency regulations are more vague, the description of the monitoring point is not clear enough, such as the "petrochemical industry pollutant emission standards" and "synthetic resin industrial pollutant emission standards" did not put forward the frequency of monitoring of pollutant indicators, although the monitoring indicators, emission limits, but some monitoring points are not clear; The Measures for Self-Monitoring and Disclosure of Information by State Key Monitoring Enterprises (Trial) put forward some requirements for the frequency of monitoring of state-controlled enterprises, but as a normative management document, the provisions are relatively general and cannot meet the requirements for self-monitoring programming of large-format petrochemical enterprises
China
.
Based on this, after systematically combing the requirements of industry emissions supervision such as industry emission standards, relevant management systems and emission permit applications and issued technical specifications, the Guide refines the requirements of monitoring points, monitoring indicators, frequency of monitoring, information recording, etc., and applies to the monitoring of water, gas pollutants, noise and the quality impact of their surrounding environment during the production and operation phase.
the relevant person in charge of the Environmental Monitoring Division of the Ministry of Ecological Environment of the Ministry of Environmental Protection also said that in determining pollutant indicators, due to the large number of petrochemical industry processes and products, it is not possible to include all types in the Guide. Based on the currently implemented pollutant emission standards, and in accordance with the relevant provisions of the Petroleum Chemical Industry Pollutant Emission Standards, the Guidelines require sewage units to identify monitoring indicators on a case-by-case basis in the formulation of monitoring programmes, in the light of the Schedule to the Guidelines and the current state of production of enterprises. The selection requirements for the monitoring index of wastewater discharge from waste water discharges in petrochemical industry workshops or production facilities are the same. For the synthetic resin industry, the Guide stipulates in the Schedule that other wastewater pollutants and other exhaust gas pollutants to be monitored for the production of different products shall be separately specified, and the sewage unit shall select the monitoring indicators in accordance with the Schedule in conjunction with the production status of the unit.
addition, the head of the Environmental Monitoring Department of the Ministry of Ecological Environment said that the sewage permit system is an important carrier for the self-monitoring and implementation of sewage units, and the self-monitoring technical guide is one of the important technical support documents for sewage permit management. The application for and issue of technical specifications for sewage permits for the petrochemical industry has been issued and implemented, although these standards already contain self-monitoring requirements, but after the release and implementation of the industry self-monitoring technical guidelines, self-monitoring requirements shall be based on the provisions of the Guidelines.
