Inner Mongolia Kunshuntai Building Materials Technology Co., Ltd.:
About the Comprehensive Utilization of Carbide Slag by Inner Mongolia Kunshuntai Building Materials Technology Co., Ltd. We have received the Application for Approval of the Environmental Impact Report of the Production Project of New Wall Materials Produced by Fly Ash and the Environmental Impact Report of the Production Project of New Wall Materials Produced by Comprehensive Utilization of Carbide Slag and Fly Ash of Inner Mongolia Kunshuntai Building Materials Technology Co., Ltd. prepared by Inner Mongolia Lvzhiyin Environmental Protection Technology Development Co., Ltd. After deliberation by our Bureau, the construction of the project is approved, and the reply is as follows. Basic Information
of the Project The project is located in Chilechuan Dairy Development Zone, Hohhot, Inner Mongolia, covering an area of 20107.7 square meters. The project constructs two fully enclosed workshops, with production area, secondary processing area, maintenance area, raw material storage area, defective product area, etc., and supporting construction of cement silo, fly ash silo, finished product area, office dormitory building, etc. The scale is to produce 10 million environmental protection bricks, 5 million light partition bricks, 50000 cubic meters of PC bricks, 10000 cubic meters of aerated concrete blocks, 5000 cubic meters of concrete and 6000 meters of exhaust and drainage inspection wells annually. The total investment of the project is 58 million yuan, including 9.22 million yuan for environmental protection, accounting for 15.9% of the total investment.
The project is a new project, which must obtain the approval procedures of relevant departments in strict accordance with national laws and regulations and relevant provisions, and is feasible after the full implementation of the pollution prevention and control measures proposed in the report form.
2. The following tasks
should be focused on in project construction and operation management: 1. Strengthen environmental management during construction period. The construction wastewater of the project shall be reused after treatment; the dust suppression measures shall be taken to reduce the pollution of construction dust; the construction equipment shall be reasonably arranged, and the low-noise equipment shall be selected. The construction noise shall conform to the Emission Standard for Environmental Noise at Boundary of Construction Site (GB12523-2011) and the relevant requirements of the acoustic environment function area in the area.
2. Do a good job in air pollution prevention and control. The loading and unloading, storage, transportation, feeding of raw materials and all production processes of the project are closed. The top of the fly ash silo and cement silo is equipped with dust removal equipment. The dust produced by crushing, batching, mixing, shot blasting and other processes is collected to the bag dust removal equipment for treatment and then discharged by the exhaust funnel in accordance with the height requirements. The organized emission of dust shall comply with Table 2 of the Emission Standard of Air Pollutants for Brick and Tile Industry (GB29620-2013), and the unorganized emission of dust shall comply with Table 3 of the Emission Standard of Air Pollutants for Brick and Tile Industry (GB29620-2013); Canteen lampblack exhaust gas is treated by lampblack purification equipment and discharged to the roof after meeting the limit requirements of the Emission Standard for Cooking Fume (GB18483-2001).
Implement energy-saving technological transformation, establish energy management system, and realize no increase in greenhouse gas emissions.
3. Strengthen the protection of water environment. The waste water generated from cutting and polishing processes shall be reused for production after sedimentation treatment, and shall not be discharged; the domestic sewage shall be treated by oil separator and septic tank, and shall be discharged into Jinshan Sewage Treatment Plant through the sewage pipe network for treatment after meeting the Class III standard of Integrated Wastewater Discharge Standard (GB8978-1996) and the water quality requirements of Jinshan Sewage Treatment Plant.
4. Strictly control the environmental impact of noise. The noise emission at the factory boundary must meet the requirements of Class 3 standards in the Emission Standard for Industrial Enterprises Noise at Boundary (GB12348-2008).
5. Strengthen solid waste management. Concrete scraps, aerated block cutting waste, sediment in the sedimentation tank, dust collected by the dust collector, and nonconforming products are reused for production; waste packaging materials are transported for comprehensive utilization; domestic garbage is disposed of by the environmental sanitation department; waste mineral oil, waste oil barrels and other hazardous wastes are classified and temporarily stored in the temporary storage room for hazardous wastes in the plant area, and are transferred and disposed of by qualified units. The project shall be equipped with general solid waste temporary storage and hazardous waste temporary storage with sufficient capacity in the plant area, which shall be managed in strict accordance with the requirements of Standard for Pollution Control on the Storage and Disposal Site of General Industrial Solid Waste (GB18599-2020) and Standard for Pollution Control on Hazardous Waste Storage (GB18597-2023).
6. Do a good job of project environmental information disclosure and establish and improve relevant systems. Construction units must strictly implement the relevant requirements of the Information Disclosure Mechanism Scheme for Environmental Impact Assessment of Construction Projects and the Measures for Public Participation in Environmental Impact Assessment.
7. Strictly implement other environmental impact prevention and control measures proposed in the EIA report to ensure that pollutants meet the discharge standards.
3. The project construction must strictly implement the "three simultaneous systems" of environmental protection in which the supporting environmental protection facilities and the main project are designed, constructed and put into operation at the same time. The project must develop and implement an environmental monitoring plan in accordance with the relevant provisions on pollutant discharge permits and self-monitoring, and apply for a pollutant discharge permit before starting production facilities or actually discharging pollutants. After the completion of the construction project, the construction unit shall independently check and accept the supporting environmental protection facilities.
4. If the nature, scale, location or pollution prevention measures of the project have changed significantly, the environmental impact assessment documents of the project shall be re-submitted for approval before the start of construction.
5. The Tumote Left Banner Branch of Hohhot Ecological Environment Bureau is responsible for the environmental monitoring and post-event supervision of the project during the construction and operation periods.
