I. Project Overview Henan Tianyi Steel Structure Engineering Co., Ltd. is located in the Heqi Industry Cluster of Qixian County, Hebi City. It is planned to invest 60 million yuan across the old woolen mill in the middle of Zhonghua Road, Tiexi Industrial Zone, Qixian County, and lease Hebi Chaoge Cotton Spinning Co., Ltd. The company's land construction project with an annual output of 6,000 sets of light steel assembled house components and an annual output of 1,300 tons of steel structure. This project uses steel and steel as raw materials, and adopts cutting, welding, plate straight, anti-corrosion (paint painting), testing and other production processes. The annual output of 1,300 tons of steel structure production line, doors and windows, structural supports, wall panels, railings and other materials purchased outside, An annual output of 6000 sets of light steel assembly house production line. This project is a newly-built project, and the Qi County Development and Reform Commission approved the project for the record with the approval number of 2019-410622-43-03-004624.
2. Disclose the environmental assessment information to the public. The full text of the environmental assessment is shown in the annex. The pollution prevention and environmental impact during the operation period are as follows:
2.1 Exhaust gas During the operation period of the project, exhaust gas is mainly particles generated during the cutting process, welding process, shot blasting process, paint mist, paint mist generated during drying process, non-methane total hydrocarbons and xylene. The particulate matter generated during the cutting process and welding process is processed by the air collection hood + bag type dust collector, and is discharged through a 17m high exhaust cylinder. The particulate matter generated by the shot blasting process is processed by a bag type dust collector, and passed through a 17m high exhaust cylinder. The paint mist, non-methane total hydrocarbons, and xylene produced in the spray-drying process are collected by negative pressure, and then enter the UV photo-oxygen catalysis + activated carbon adsorption device for treatment, and then discharged through a 17m high exhaust cylinder. After treatment, the emissions of particulate matter can meet the secondary standards of the "Ambient Air Quality Standard" (GB3095-2012), and the emissions of non-methane total hydrocarbons and xylene can meet the requirements of the "Regulations on the implementation of special treatment of volatile organic compounds in industrial enterprises in the province". Notice of Proposed Value "(Yuhuan Tackling Office  No. 162).
2.2 Wastewater During the operation period of the project, no production wastewater is used and generated. There are no office and living areas in the factory area, and the aqua latrines are regularly cleaned by nearby villagers as fertilizer fertilizer fields.
2.3 Noise is mainly the noise generated during the operation of machinery and equipment. After the basic vibration reduction and wall sound insulation, the noise value at the factory boundary can reach the Class 2 standard of "Environmental Noise Emission Standard for Industrial Enterprise Factory Boundary" (GB12348-2008).
2.4 Solid waste The general solid waste generated by this project is steel scraps, dust collected by the dust removal system, scrap steel pellets, etc., which are regularly sold after collection. After domestic garbage is collected, it is regularly transported to the nearby garbage collection station. Dangerous solid waste waste paint buckets, waste thinner buckets, waste filter cottons, waste activated carbon, waste lubricants, waste hydraulic oil, etc. are collected and temporarily stored in the hazardous waste temporary storage room, and regularly delivered to the corresponding qualified units Disposal. The replacement of the waste light tube of the UV photo-catalytic device is directly recycled after the original manufacturer replaces it.
3. Main matters for public opinions The public opinions and opinions of the social groups on environmental issues, social issues and vital interests brought about during the construction and operation of the project, as well as suggestions for the survey of public opinions .
