Semiconductor discrete device manufacturing project" of Jiangsu Weida Semiconductor Co.
Environmental Protection Acceptance Opinions
On September 26, 2020, Jiangsu Weida Semiconductor Co., Ltd. organized an environmental protection acceptance meeting for the "Semiconductor Discrete Device Manufacturing Project". The acceptance working group consisted of Jiangsu Weida Semiconductor Company Limited and 2 experts. The participants visited the construction and operation site of "Semiconductor Discrete Device Manufacturing Project", listened to the report and explanation of project construction and operation, acceptance report preparation and acceptance report conclusion, etc. After full discussion, the "Semiconductor Discrete Device Manufacturing Project" was formed as follows "Environmental protection facilities acceptance comments are as follows:
A, the basic situation of engineering construction
(A) construction location, scale, main construction content
The project is located in the Weiyang Economic Development Zone Ecological Science and Technology Park, building 8, the first and second floors, the main production of discrete semiconductor devices (silicon chips 120,000 pieces, semiconductor discharge tube chip 60,000 pieces, transient suppression diode chip 60,000 pieces, silicon controlled into 18,000,000 pieces).
The main construction scale and content of the project is 120,000 silicon chips, 60,000 semiconductor discharge tube chips, 60,000 transient suppression diode chips, 18,000,000 silicon controlled into the tube production capacity and supporting equipment.
(B) Construction process and environmental protection approval
In June 2018, Jiangsu Weida Semiconductor Co., Ltd. commissioned Jiangsu Zhihuan Technology Co., Ltd. to prepare the "Jiangsu Weida Semiconductor Co., Ltd. semiconductor discrete device manufacturing project environmental impact report form", the project obtained the approval of Yangzhou Yujiang District Environmental Protection Bureau on November 19, 2018 (Yangzhou Yujiang Environmental Protection Bureau [2018] No. 122).
On June 15, 2020, Jiangsu Weida Semiconductor Co., Ltd. organized an acceptance review meeting for the completion of the "semiconductor discrete device manufacturing project" for "wastewater, exhaust gas and noise", and the acceptance team agreed that the project "wastewater, exhaust gas and noise pollution prevention and control facilities for environmental protection". The acceptance team agreed that the project "passed the environmental protection acceptance of wastewater, exhaust gas and noise pollution prevention and control facilities". (C) Investment
Project investment of 60 million, including environmental protection investment of 2.19 million. (D) Acceptance scope
The scope of this acceptance is "semiconductor discrete device manufacturing project" involving solid waste pollution prevention and control facilities.
Second, the project changes
Ltd. "semiconductor discrete device manufacturing project" in the construction process, (1) further clarify the chemical reagents (silicon chips production) temporarily stored in the raw material library ①, silicon tube production materials stored in the raw material library ②. (2) accident emergency pool increased by 43m3.
The above changes (1) in the clear fire, safety conclusion conditions, does not belong to the "major changes". Third, the effect of commissioning environmental protection facilities
The solid waste generated by the project includes general industrial solid waste, hazardous waste and domestic garbage. Domestic garbage: After collection, it will be entrusted to Yangzhou City Yujiang District Environmental Health Management Office by Yangzhou Ke Guang Auto Electronic Electric Co.
Hazardous waste: waste organic solvent, waste photoresist, waste developer wash, waste negative adhesive stripping liquid, waste cotton ball, waste resin, waste machine oil, waste filter sieve, waste activated carbon, waste water washing tower liquid, fluorine sludge, waste chemical packaging is entrusted to Gaoyou Kangbo Environmental Resources Co. The storage area is 67m2;
General industrial solid waste: waste silicon wafers, waste aluminum, waste titanium nickel silver metal, waste chips, unqualified chips, general waste packaging collected centrally and sold; waste latex source, waste glass powder, waste blue film, waste plastic, waste activated carbon, waste filter membrane, waste filter element, waste saw blade collected centrally and entrusted to the local sanitation department for cleaning and disposal.
IV. Acceptance conclusion
Ltd. can be in accordance with the "Semiconductor Discrete Device Manufacturing Project Environmental Impact Report Form" and its approval requirements for construction; acceptance monitoring period, the pollutants can meet the standard emissions, wastewater and waste gas pollutants in line with the total annual emissions of the EIA and approval requirements; there is no "Interim Measures for Acceptance of Environmental Protection Inspection of Construction Project Completion" (National Environmental Regulations and Environmental Assessment [2017] No. 4) in Article 8 Not to accept the situation of qualified.
The inspection and acceptance team considers that the acceptance of environmental protection facilities of "Semiconductor Discrete Device Manufacturing Project" is qualified.
V. Follow-up requirements
1、Production and operation in strict accordance with the project EIA and approval requirements.
2, strengthen environmental management, improve the operation and maintenance management of wastewater, waste gas, noise and solid waste pollution control facilities, and strengthen the effective collection, treatment/disposal of the "three wastes".
3、Strengthen the management of environmental safety risk prevention, strengthen emergency training and emergency drills, to ensure that environmental safety risk prevention is fully effective.
4、Strictly in accordance with the requirements of the existing norms, strengthen material accounting, verify the type and amount of hazardous waste generated; strengthen the effective collection, storage and standardized treatment and disposal of various types of solid wastes, especially hazardous wastes, and supplement and improve the risk prevention measures for hazardous wastes.
5, in accordance with standard requirements, self-monitoring, and do a good job of information disclosure.
6, the completion of the construction project to improve the environmental protection acceptance monitoring report and other matters.
