It is understood that in order to successfully promote the transformation and development of traditional coal chemical industry, January 1, 2019, letter to the Office of Henan Province workers released a special action program (hereinafter referred to as the "Program"), to promote pollution prevention campaign of Henan Province, three-year action implementation of the scheme, to speed up the traditional coal chemical industry (ammonia, methanol) industry green transformation, to achieve high-quality development. "Program" details are as follows.
First, the key tasks
1, and strictly control new capacity. Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity.
2, increase the relocation and reconstruction efforts. Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), in situ transformation of the company to implement the upgrading of the standard industry benchmark, off-site relocation of enterprises to According to large-scale, modern principles move into the province for involving chemical industry gathering area.
3, Green transformation. Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. In accordance with national requirements, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place.
Second, the organization and implementation
1, roles and responsibilities. Relevant provincial jurisdiction over municipal government on the development of local coal chemical industry restructuring and overall responsibility, strengthen organizational leadership, with local conditions, the development of coal chemical industry restructuring and development program implementation, implementation tasks initiatives. Coal chemical industry is the main responsibility for the implementation of the restructuring and development, to strictly implement the main responsibility for production safety and environmental protection, the implementation of the relocation of the green transformation.
