Summary

(1)　 The Inner Mongolia Huaxin Mengzheng Solid Waste Treatment Company submitted a report titled "Environmental Impact Report for the 30,000t/year Incineration Treatment Project of Inner Mongolia Huaxin Mengzheng Solid Waste Treatment Company (Revision)". After reviewing the report, the Inner Mongolia Autonomous Region Environmental Protection Bureau approved the project with the following conditions:

(2)　 The project is located within the Huaxin Hazardous Waste Treatment Center in Fengzhen City, Ulanqab City, Inner Mongolia. The project is an expansion of the original 30,000t/year incineration treatment project, which was approved by the Ulanqab City Ecological Environment Bureau in February 2020. The main changes to the project include replacing a single rotary kiln with two turbulent fluidized bed (TFB) incinerators, adding 20,000t/year of general industrial waste incineration capacity, and installing additional equipment such as pre-treatment systems, class A and class B storage facilities, liquid hazardous waste storage areas, heat recovery systems, and ash storage facilities.

(3)　 The project's hazardous waste incineration capacity remains at 30,000t/year, with the first phase having a capacity of 20,000t/year for hazardous waste and 10,000t/year for general industrial waste, and the second phase having a capacity of 10,000t/year for hazardous waste and 10,000t/year for general industrial waste.

(4)　 The report states that the project meets the "14th Five-Year Plan for the Utilization and Treatment of Hazardous Waste Facilities in Inner Mongolia Autonomous Region" and that, under the premise of implementing all ecological protection and pollution prevention measures, the project's environmental impact can be mitigated and controlled. Therefore, the bureau approves the project, subject to the following conditions.

(5)　 During the design, construction, and operation of the project, the following work must be done:

(6)　 1. Strictly implement air pollution prevention measures. The pre-treatment system's exhaust gases must be sent to the incinerator for treatment, and the treated flue gas must meet the air pollution standards specified in the "Hazardous Waste Incineration Pollution Control Standard" (GB18484-2020). The exhaust gases from the storage facilities and containers must be treated and meet the standards specified in the "Odor Emission Standards" (GB14544-93) and the "Comprehensive Emission Standards for Air Pollutants" (GB16297-1996). 2. Strictly implement water pollution prevention measures. The saltwater produced by the saltwater preparation system, the heat recovery boiler's wastewater, and the floor washing wastewater must be reused for production. The wastewater from the odor removal device's absorption tower must be treated by the existing wastewater treatment plant of Huaxin Green Source Company and reused for production. Any wastewater containing first-class pollutants and other toxic and hazardous pollutants must be treated within the workshop and meet the standards. 3. Enhance environmental risk control. Strictly implement the environmental risk prevention measures proposed in the report. Establish an environmental risk management system, formulate an emergency response plan, and conduct regular emergency drills. Ensure that the project has a sufficient emergency team, equipment, and materials. Implement a classification management, graded response, and regional coordination system to handle environmental emergencies. 4. Strictly implement solid waste pollution prevention measures. Follow the principle of "reduction, resource utilization, and harmless treatment" to handle various types of solid waste. The ash, fly ash, and dust from the incinerator, as well as the activated carbon, filter bags, and mineral oil from the odor removal system, must be collected and sent to the hazardous waste landfill for disposal. Hazardous waste, such as lead-acid batteries, must be sent back to the manufacturer or a qualified unit for recycling or disposal. 5. Strictly implement noise pollution prevention measures. Prioritize the use of low-noise equipment, optimize the layout of high-noise equipment, and implement noise reduction measures such as soundproofing, sound insulation, and vibration reduction to ensure that the factory's noise meets the standards specified in the "Industrial Enterprises' Factory Boundary Environmental Noise Emission Standard" (GB12348-2008). 6. Strictly implement operational pollution source monitoring plans. Establish a comprehensive monitoring system for organized and unorganized pollution sources, covering routine pollutants and characteristic pollutants. If any pollutants exceed the standards, the cause must be identified and further measures must be taken to reduce pollution.

(7)　 The project must strictly implement the "three simultaneous" system, which requires the environmental protection facilities to be designed, constructed, and put into operation simultaneously with the main project. The environmental protection measures must be optimized and refined, and the revised measures and budget must be included in the design, construction, and bidding documents, and the responsibilities must be clearly defined. After the project is completed, the environmental protection measures must be inspected and evaluated, and any hidden dangers must

(1)　 内蒙古华新蒙正固体废弃物处置有限公司：

(2)　 你公司报送的《内蒙古华新蒙正固体废弃物处置有限公司3万t/年焚烧处置项目（变更）环境影响报告书》（以下简称《报告书》）收悉。经研究，批复如下：

(3)　 一、该项目位于乌兰察布市丰镇市华新危险废物处置中心厂区内，属于变更项目，原项目为内蒙古华新蒙正固体废弃物处置有限公司3万吨/年焚烧处置项目，由乌兰察布市生态环境局2020年2月21日以乌环审〔2020〕8号文件予以环评批复。本期工程变更内容主要包括: 焚烧处置设施由单台回转窑变更为两台湍动流化床（TFB），新增2万吨/年一般工业固废焚烧处置能力，配套预处理系统、甲乙类库、丙类库、液体危险废物储存区、余热发电系统及灰渣仓等。危险废物焚烧处置能力维持3万吨/年不变，一期工程为危险废物焚烧处置能力2万吨/年、一般工业固废焚烧处置能力1万吨/年；二期工程为危险废物焚烧处置能力1万吨/年、一般工业固废焚烧处置能力1万吨/年。
