Announcement of Environmental Impact Assessment of Machine-made Sand Project with Annual Output of 1 Million Tons in Yichun, Jiangxi

Recently, Yichun Municipal Bureau of Ecology and Environment approved the environmental impact assessment of the construction project of Yichun Highway Construction Group Subgrade Branch of Jiangxi Province with an annual output of 1 million tons of machine-made sand. Located at No.20, Chunyi Road, Yichun Economic and Technological Development Zone, Yichun City, Jiangxi Province,

the project covers an area of 43933 square meters and a building area of 13300 square meters. With a total investment of 400 million yuan, it is a new project. After jaw crushing and cone crushing, the purchased gravel is transported to the sand washing process by belt, and the materials with different particle sizes are screened and sold.

The project is a new project. After jaw crushing and cone crushing, the purchased gravel is transported to the sand washing process by belt, and the materials with different particle sizes are screened and sold. The total investment of the UNK7 project is 400 million yuan, of which 1 million yuan is invested in environmental protection, accounting for 0.25% of the total investment. 0HTML0UNK8 Major environmental impacts and countermeasures and measures to prevent or mitigate adverse environmental impacts: (1) Strictly implement air pollution prevention and control measures. Clean production measures should be taken to reduce the amount of waste gas. According to the category and nature of the pollutants in the waste gas, the mature and reliable treatment process is adopted. During the operation period of the Project, the organized emission of waste gas is crushing and grinding dust, and the unorganized emission of waste gas includes crushing dust, dust from product storage yard, dust from loading and unloading, and dust from transportation. 0 HTML 0 UNK9 The main pollutants of crushing and grinding dust are particles, which are collected by the dust hood and treated by the impact water bath dust collector to meet the Grade II standard of "Emission Limits of Air Pollutants from New Pollution Sources" in the Integrated Emission Standard of Air Pollutants (GB16297-1996), and are discharged by the 15-meter-high exhaust funnel. HTML 0 UNK1 0 The main pollutants of unorganized exhaust gas are particulate matter. The emission concentration and emission rate of particulate matter meet the unorganized emission monitoring concentration limit in Table 2 of the Integrated Emission Standard of Air Pollutants (GB16297-1996). HTML 0 UNK1 1 (2) Strictly implement water pollution control measures. The discharged wastewater of the project is mainly domestic sewage; the vehicle washing wastewater is recycled after sedimentation in the sedimentation tank. 0 HTML0 UNK1 2 The pH, CODcr, ammonia nitrogen, BOD5, SS, TP and TN in the discharged wastewater meet the pipe acceptance standard of the wastewater treatment plant in the Economic and Technological Development Zone, and other factors meet the primary standard in Table 4 of the Integrated Wastewater Discharge Standard (GB8978-1996). Then discharged into the park sewage treatment station to meet the first class A standard of the Discharge Standard of Pollutants for Urban Sewage Treatment Plant (GB18918-2002), and then discharged into the yuanhe River through the Wo River. HTML 0 UNK1 3 (3) Strictly implement noise pollution prevention and control measures. Optimize the general layout of the project, arrange high-noise equipment reasonably, select low-noise equipment as far as possible, and take effective measures to control the noise impact. The noise at the factory boundary must meet the Class 3 standard in the Emission Standard for Industrial Enterprises Noise at Boundary (GB12348-2008). HTML 0 UNK1 4 (4) Strictly implement measures for classified disposal and comprehensive utilization of solid waste. The general solid waste produced by the project is sludge; the hazardous waste is waste engine oil. Meet the requirements of Standard for Pollution Control on Storage and Landfill of General Industrial Solid Wastes (GB18599-2020) and Standard for Pollution Control on Storage of Hazardous Wastes (GB18597-2023). HTML0 UNK1 5 (5) Strictly implement environmental risk prevention measures. Strictly implement the environmental risk provention and control measures proposed in the Report Form. We will improve the enterprise's environmental risk prevention and emergency management system, and formulate provention and control measures for environmental risks throughout the plant and contingency plan for environmental emergencies. The contingency plan of environmental emergencies shall be reported to the local ecological environment department for the record. 0 HTML0 UNK1 6 (VI) Standardized requirements for sewage outlets. Standardized pollutant discharge outlets shall be set up according to relevant national, provincial and municipal regulations, and signboards shall be set up. The height of each process waste gas exhaust funnel must meet the requirements of corresponding standards and the Report Form, and sampling outlets shall be set up according to the requirements. 0 HTML0 UNK1 7 (7) Planning control requirements around the project. According to the conclusion of the Report Form, the health protection zone of this project is determined to be within 50m from the plant boundary. Your company should cooperate with the Management Committee of Yichun Economic and Technological Development Zone to strictly control the surrounding planning of the project, and no new environmentally sensitive buildings such as residential buildings, schools and hospitals should be built within the health protection distance of the project. 0HTML0UNK18
