I. Project Overview Qixian Hengyuan Mining Co., Ltd. is a state-owned enterprise jointly established by Hebi Hengyuan Mining Group Co., Ltd. and Qixian Yuanxin Investment Management Co., Ltd. According to the “Notice on Printing and Distributing the Implementation Plan of the Three-year Action Plan for the Comprehensive Management of Open-pit Mines in Henan Province (2018-2020)” of the Office of the Joint Conference of Important Mineral Resources Management of Henan Province (Yu Mine Joint Office  No. 1), Regarding the relevant requirements of the "Implementation Scheme for Comprehensive Reconstruction of Building Stones and Mining" and "The Third Round of Mineral Resources Planning in Hebi City", Qixian Hengyuan Mining Co., Ltd., as the integration and development of Qixian general construction stone mines, is the subject of integration and development of Qixian County. Abandoned mines will be rehabilitated, and at the same time, according to the stone quality index measurement, the debris generated during the remediation process (abandoned slag in the abandoned mining area and weathered steep gravel that may easily cause rock and soil collapse, landslide geological disasters) can be used as sand. Reuse of stone aggregates. Therefore, the construction of an ecological comprehensive treatment project for abandoned mines in Qi County will be constructed with a production line of 5 million tons of gravel aggregate.
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
Waste gas crushing dust, screening dust, transfer dust and storage dust during project operation. All production equipment, transportation belts (fully enclosed corridors) and products of this project are located in fully enclosed workshops, and gas collection and dust suppression measures are adopted at each dust production point. The particle emission concentration meets the requirements of the "Construction Stone, Stone Green Mine Construction" Requirements for particulate matter emission concentration (10mg / m 3 ) in Appendix A of the Code (DB41 / T1665-2018). The concentration of particulate matter at 20m outside the plant boundary around the project site can meet the requirements for the concentration limit for monitoring the fugitive emissions (≤0.5mg / m 3 ) at 20m outside the plant boundary in the Cement Industry Air Pollutant Emission Standard (GB4915-2013).
2.2 Wastewater During the project operation period, no production wastewater is generated. During the production process, dust suppression water and road dust reduction water all enter the product or are evaporated without discharge; the vehicle washing wastewater is recycled after sedimentation; green water is evaporated without discharge; domestic sewage is passed through a septic tank. After treatment, it will be used in surrounding farmland and fertilizer fields. The wastewater treatment measures of the project are feasible and have little impact on the surrounding surface water environment.
2.3 Noise is mainly the noise generated during the operation of machinery and equipment. After basic vibration reduction and wall sound insulation, the noise value at the boundary of the factory can reach the Class 2 standard of "Environmental Noise Emission Standard for Industrial Boundary of Industrial Enterprises" (GB12348-2008).
2.4 Solid waste
The general solid waste generated in the production process of this project includes dust collected by bag dust collectors and domestic garbage of employees. The dust collected by the bag filter is directly sold as products; domestic garbage is collected in the factory area and sent to the garbage transfer station for disposal. The hazardous solid waste of this project is the waste cotton yarn and waste lubricating oil produced during the mechanical maintenance process during the production process, which are temporarily stored in the company's hazardous waste temporary storage room and then submitted to the qualified unit for treatment.
