Therefore, the solid waste disposal measures taken by the Project were technically reasonable and feasible.
5. Environmental Impact Analysis
(1) Environmental impact on surface water:
After the construction of the Project, the cyanide-containing wastewater will be treated by the cyanide-containing wastewater treatment system. The bioactive wastewater will be treated by the HPHT inactivation system, and then mixed with other wastewater into the wastewater treatment station of the plant. After the formaldehyde and the total organic carbon meet the requirements of Table 2 of the Discharge Standard of Water Pollutants for Pharmaceutical Industry Bio-pharmaceutical Category (GB21907-2008), the chloride meet the reference requirements of Class B standard of the Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T31962-2015), and the other indicators meet the applicable discharge standard limits for wastewater discharge permission in High-tech Zone, Chengdu, the wastewater will be discharged into the cooperative wastewater treatment plant for further treatment before discharged into Qingshui River. This Project is located within the range of wastewater collection range of the cooperative wastewater treatment plant which is capable of receiving the wastewater from the Project. The quality of the wastewater from the Project will not affect the normal operation of the wastewater treatment plant. After treated and drained at the standard level, the wastewater exerts a slight impact on the water quality of Qingshui River.
(2) Groundwater impact analysis
In order to minimize the pollution to groundwater, the plant is designed with seepage prevention by zones and associated seepage prevention measures were taken for different prevention and control areas. Based on the implementation of the groundwater pollution prevention measures proposed in the Statement, the project construction had a small impact on local groundwater environment.
(3) Atmospheric environmental impact
The waste gas in the Project can be emitted at a standard level after corresponding treatment measures are taken. AERSCREEN estimation model is used to calculate the waste gas emission under normal working conditions of the Project. The calculation results indicate that, under normal working conditions, the largest proportion of air pollutants emitted by the Project is hydrogen chloride (accounting for less than 10%) from the unorganized emission of the Quality Inspection and R&D Center. Therefore, the atmospheric environmental impact of the Project is assessed as Grade 2. The impact of the Project on the atmospheric environment is acceptable.
(4) Acoustic environmental impact
By rationally arranging noise sources, selecting low-noise equipment as far as possible and taking appropriate noise reduction measures such as sound insulation, noise reduction and vibration reduction, the noise source intensity of the Project will be greatly reduced, and the noise contribution value is between 18.70 and 32.19dB(A). The boundary noise of the Project could meet the requirements of Class 3 standard of the Emission Standard for Industrial Enterprises Noise at Boundary (GB12348-2008), and the noise of sensitive points could meet the Class 2 standard in the Environmental Quality Standards for Noise (GB3096-2008). Therefore, the construction of the Project has little impact on the acoustic environment of the project area located and will not change the function of the regional sound environment.
(5) Soil environmental impact
The soil environmental quality in the project area meets the requirements of the screening value of the second category of land in the Soil Environmental Quality - Risk Control for Construction Land Soil Pollution (GB/T36600-2018). On the basis of strengthening flood control, leakage control, waste gas treatment and emergency treatment, the Project controls its own strong pollution sources on the regional soil environment from the source to ensure that the impact of the Project on the regional soil environment is at an acceptable level.
(6) Solid waste impact
The solid waste from the Project includes hazardous waste and general waste. Hazardous waste is classified and temporarily stored in a temporary storage warehouse for hazardous waste, and regularly handed over to the organizations with hazardous waste treatment qualifications for unified cleaning and disposal. General industrial solid waste is classified and temporarily stored in a temporary storage warehouse for general waste and regularly cleared. The temporary storage warehouse for hazardous waste shall be constructed in strict accordance with the requirements of the Standard for Pollution Control on Hazardous Waste Storage (GB18597-2001), and shall be treated against wind, rain, sunlight and seepage measures and provided with impermeable and anti-corrosion drainage trenches or cofferdams. The solid waste from the Project is disposed at a clear destination and will not cause secondary pollution to the surrounding environment.
(7) Environmental risk impact analysis
The Project involves the use and storage and transport of many kinds of hazardous chemicals, and the ratio of the quantity of hazardous substances to the critical quantity is Q<1. The risk potential of the Project is Grade I and the environmental risk evaluation is rated as simple analysis. The most conceivable environmental risk accident of the Project is environmental pollution and poisoning caused by the diffusion of pollutants after material leakage. During the operation of enterprises, risks and hidden dangers can be minimized by establishing strict risk prevention measures, strengthening training on employees’ ability to prevent incident risks, developing emergency plans and incident emergency plans, and timely tracking and revising them, making the environmental risks prevented and controlled.
In summary, the environmental risk assessment of the Project is rated as simple analysis; the project risk control measures are effective and reliable; as long as the relevant requirements for environmental risk management of the Project are implemented conscientiously, the environmental risks of the Project can be prevented and controlled from the perspective of environmental risks.
