Public Notice Prior to Approval of the Environmental Impact Assessment Report for the Project of Adjusting, Relocating, Upgrading and Transforming the Ammonium Alcohol Raw Material Production Route with an Annual Output of 300,000 Tons by Anhui Haoyuan Chemical Group Co., Ltd. Author/Source: Fuyang People’s Daily** Date: 2019-07-02 Clicks: 23 Project Name: Project of Adjusting, Relocating, Upgrading and Transforming the Ammonium Alcohol Raw Material Production Route with an Annual Output of 300,000 Tons Contractor: Anhui Haoyuan Chemical Group Co., Ltd. Location of Construction: Yingdong Coal-based Industrial Park Agency responsible for preparing the environmental impact assessment document: Hebei Qizheng Environmental Technology Co., Ltd. Overview of the construction project: This project is located within the Fuyang Coal-based New Materials Industrial Park in Anhui Yingdong Economic Development Zone, on industrial land. The project involves demolishing 20 fixed-bed gas generation furnaces in the old plant area of Anhui Haoyuan Chemical Group Co., Ltd., and constructing a new production facility with an annual capacity of 300,000 tons of syngas in the new plant area. This facility includes a gasification unit, a shift converter unit, a low-temperature methanol washing system, as well as auxiliary systems such as coal storage and transportation facilities, air separation units, and sulfur recovery units. The gasification process was upgraded from a fixed-bed gasifier to a dry coal powder HT-L pressurized fluidized bed gasification process, while the desulfurization process was upgraded from the tannin-based desulfurization method to the low-temperature methanol washing process. Upon completion of the proposed project, the new plant of Haoyuan Chemical will gain an additional production capacity of 300,000 tons per year of syngas, which will fill the gap in syngas supply generated by the \"dimethyl ether project\". This will enable its production facilities to operate at full capacity, resulting in a production capacity of 500,000 tons of dimethyl ether per year. The total investment for this project is 1,121,882,300 yuan, of which 4.9 million yuan is allocated to environmental protection measures. Environmental impacts and countermeasures (main contents to be approved): 1. Adopt advanced and reliable measures for the control of waste gas pollution to effectively reduce uncontrolled emissions of waste gas. In various types of process exhaust gases, SO2 and sulfuric acid mist are treated by the appropriate exhaust gas treatment facilities, resulting in levels that meet the secondary standards specified in Table 2 of the \"Integrated Emission Standards for Air Pollutants\" (GB16297-1996), as well as the limit values for unorganized emissions. After treatment, the H2S in process exhaust gases meets the standards specified in Table 1, category II for \"new construction, expansion, or renovation\" under the \"Emission Standards for Odorous Pollutants\" (GB14554-93), as well as the emission limit values listed in Table 2. After treatment, organic exhaust gases meet the limit requirements specified for \"other industries\" in Table 2 of the \"Emission Control Standards for Volatile Organic Compounds in Industrial Enterprises in Tianjin\" (DB12/524-2014). Online monitoring facilities shall be installed as part of the process waste gas collection and treatment systems, and connected to the environmental protection authorities. 2. The project should have separate systems for rainwater and sewage, as well as for clean water and wastewater. Construction wastewater must be collected uniformly; temporary sedimentation tanks for such wastewater should be installed, and the clear water can be reused. The purified rainwater is discharged into the municipal rainwater network of the park through the plant’s rainwater drainage system. The wastewater from the circulating water station is directly fed into the plant’s reclaimed water reuse system and not discharged outside. The domestic wastewater and other production wastewater generated within the plant are collected and sent through the plant’s wastewater pipeline system to the plant’s wastewater treatment station. This wastewater treatment station has a capacity of 420 m3/h, and it uses a treatment process that includes air flotation, hydrolysis-acidification, contact oxidation, and two-stage aerated biological filters. After treatment, the wastewater meets the indirect discharge concentration limits specified in Table 2 of the \"Emission Standards for Water Pollutants in the Synthetic Ammonia Industry\" (GB13458-2013), as well as the standards set for wastewater treatment plants in coal-based new material industrial parks; thereafter, it is sent to the park’s wastewater treatment station for further processing. Not excreted. During the engineering design and construction of the project, reasonable anti-seepage measures should be taken for areas such as the sewage treatment area, sewage pipelines, production unit areas, and tank areas, in order to prevent contamination of groundwater. 3. Choose low-noise equipment, arrange various types of equipment reasonably, and strengthen maintenance and management. During the construction phase, noise levels must comply with the relevant provisions of the \"Standards for Environmental Noise Emissions at Construction Sites\" (GB12523-2011); during the operation phase, noise emissions must meet the Class 3 standards specified in the \"Standards for Environmental Noise Emissions from Industrial Enterprises\" (GB12348-2008). 4. Strengthen the comprehensive utilization of solid waste, and implement measures for the temporary storage of various types of solid waste on-site, as well as their ultimate comprehensive utilization or disposal. Incinerated in the fuel of a circulating fluidized bed boiler under construction at the project’s manufacturing site ; The waste molecular sieves from air separation units are uniformly collected and processed by the manufacturers ; Sewage treatment plants generate sludge; the sludge produced in the physical and chemical treatment stages is classified as hazardous solid waste, which is handed over to qualified entities for safe disposal ; The sludge generated in the biochemical processing unit is considered ordinary solid waste, and it is transported to urban landfills for disposal ; The medium-temperature shift furnace and raw gasification slag are sold as materials for road construction or building purposes; all gasification ash is used as fuel and incorporated into the waste catalysts in the sulfur recovery catalytic reactor. The waste catalysts are considered hazardous waste, and their disposal is entrusted to qualified organizations ; The factory site is equipped with a temporary storage area of 300 m2 for hazardous waste; such waste is regularly handed over to qualified entities for disposal. The facility must have storage areas and signs for hazardous waste that meet environmental protection requirements, and the transfer of hazardous waste must be carried out in strict accordance with the \"Hazardous Waste Transfer Manifest\" system. Household waste is sorted and collected, after which it is handed over to the sanitation department for centralized removal and disposal. 5. During the operation period of the project, maintenance and management of production and environmental protection facilities should be strengthened. Dikes should be installed around the tank area, and measures should be taken to prevent accidental wastewater from escaping from the production units. The project must have emergency containment tanks to ensure that no wastewater is discharged in case of an accident; the size of these tanks must be determined through proper assessment before they are put into use. Strengthen the management of storage and transportation of hazardous raw materials and auxiliary materials, enhance preventive measures against accidents related to process exhaust gases and wastewater discharges. Based on the environmental risk assessment outlined in the Report, develop thorough emergency response plans and ensure their strict implementation during the construction phase in accordance with the principle of \"simultaneous implementation of construction, environmental protection, and safety measures,\" in order to prevent pollution incidents. 6. The people’s government of Yingdong District is requested to strictly implement the measures for relocation and resettlement aimed at achieving environmental protection objectives within a 400-meter protection zone around the project. The project shall not be put into operation until the environmental protection targets within the protection distance have been demolished. Public participation: During the preparation of the project’s environmental impact assessment documents, public participation was facilitated through methods such as on-site posting, online announcements, and newspaper publications; no feedback from the public was received during the announcement period. Our department published a notice regarding the acceptance of applications for this project on the city’s department website and the city’s ** information disclosure website; no feedback from the public was received during the notification period.
