Engineering environmental supervision and environmental management systems

Thread Content

In accordance with the requirements of the Shenzhen Environmental Protection Bureau, engineering environmental supervision and environmental management systems require environmental management and monitoring to be implemented for large-scale construction projects, both during the construction phase and during operation. The purpose of this is to implement the various environmental protection measures outlined in the environmental impact assessment report, thereby reducing the environmental impact of the project. 13.1 Engineering Environmental Supervision: Engineering environmental supervision involves establishing, after the environmental impact assessment, a comprehensive set of procedures, systems, and management frameworks to enable rapid responses to the environmental impacts associated with the construction of a project. It is a continuation of the environmental impact assessment, and it is a necessary means to ensure that the conclusions of the environmental impact assessment are implemented during the project construction phase. The purpose of engineering environmental supervision is to monitor and audit the construction units and project owners in ensuring the implementation of environmental pollution prevention measures during the project construction phase, thereby reducing the ecological impact during that period. On the one hand, engineering environmental supervision provides a mechanism to evaluate the environmental impact of construction activities ； On the other hand, it can also provide early warning for environments under construction pressure. While formulating the engineering environmental supervision plan, the detailed implementation rules for these activities should be specified in the construction contract terms related to the project construction, to ensure environmental protection. The goal of carrying out engineering environmental supervision during the construction period is to prevent or mitigate environmental pollution and damage caused by construction activities ； Implement the construction plan and schedule as required by the design documents to ensure project quality, so as to guarantee that the environmental protection facilities and the main structure of the construction project operate simultaneously. 13.1.1 The organization responsible for engineering environment supervision, as well as the construction unit, are tasked with implementing the environmental protection requirements set by the relevant environmental protection authorities during the construction phase, as well as the environmental protection measures to be adopted throughout the construction process ； It is mainly to protect the environment surrounding the construction site and prevent unnecessary damage to the natural environment. Upon completion of the project, the construction contractor shall restore and repair the environment that was damaged during the construction process. The specific technical work related to engineering environmental supervision should be carried out by an independent agency that has no conflicts of interest with the project owner and the construction contractor; such an agency should possess the qualifications and experience necessary for environmental monitoring as well as environmental impact assessment. Environmental supervision teams must be approved by the environmental protection administrative authority to ensure that they possess the appropriate qualifications and experience. 13.1.2 Engineering environmental supervision procedures: Before construction begins, the project owner must arrange for environmental supervision concurrently with the tendering process for the project construction, and work may only commence upon approval by the environmental protection authorities. Engineering environmental supervision should be carried out simultaneously with the project construction itself. Engineering environmental supervision is carried out under the oversight of the environmental protection administrative authorities, by an environmental supervision team that is employed by the project owner and is an independent third party separate from both the project owner and the construction contractors. The environmental supervision team is accountable to the local environmental protection authorities. Once entrusted by the project owner, the team shall prepare an environmental supervision plan for the project in accordance with the requirements outlined in the environmental impact assessment report, and carry out the necessary preparatory work based on the monitoring requirements specified therein. While construction is in progress, sampling and monitoring activities are carried out in accordance with the project environmental supervision plan. At the same time, inspections of the construction site or project site are conducted, analyses of the impacts of construction are performed, and environmental reviews of the construction plans are carried out. Additionally, the implementation of mitigation measures by the construction contractor is monitored, and environmental supervision reports are prepared. Reports are submitted regularly to the environmental protection authorities, and any issues that arise are reported promptly. The environmental protection administrative department conducts engineering environment supervision over the construction entity based on the engineering environment supervision report prepared by the environmental supervision team, and uses this as a basis to hold the construction entity accountable for the construction contractor. The specific arrangements for the environmental supervision team are as follows: 1. After understanding the detailed construction plan for this project, the environmental supervision team must develop a specific and detailed monitoring plan within two weeks, and revise this plan on a quarterly basis according to the actual progress of construction. The monitoring plan must be submitted to the environmental protection administrative department for review. Before construction begins, the environmental supervision team should work together with relevant departments to prepare for monitoring. 2. During the construction period, the environmental supervision team should have at least one supervisor and two technical personnel stationed on the construction site, so as to report regularly to the project owner and the environmental protection authorities, and to conduct daily inspections of the construction site. In addition to regularly submitting environmental monitoring results and review reports to the environmental protection authorities and the project owners, it is also necessary to proactively keep track of the construction schedule and actively propose mitigation measures to prevent potential environmental impacts. 3. The environmental oversight team should establish a dedicated complaint hotline and make this hotline known to the public through appropriate means. The environmental oversight team records, investigates, and addresses each complaint. The environmental supervision team is composed of the following members: Team leader: 1 ； Atmosphere and noise supervisor: 1 ； Technical monitor: 1 ； Site inspector: 1 (part-time). 13.1.3 Contents of engineering environmental supervision: During the process of engineering environmental supervision, it is necessary to determine, based on the environmental impact of the specific construction project, which aspects need to be monitored (such as water quality, air quality, noise, solid waste, soil erosion, and ecological protection). Propose respective monitoring items, placement requirements, and frequency requirements, and determine the alert levels and action plans for each agency based on the current baseline of environmental impact assessment or baseline monitoring data, as well as respective ** or local standards. Based on the characteristics of this project, soil and water loss control and monitoring measures, noise control and monitoring measures, dust control and monitoring measures, etc., have been identified as the main aspects of environmental supervision for this project. 13.1.3.1 Soil erosion: The main focus of environmental supervision regarding soil erosion is to ensure that the construction units take timely and effective measures to address soil erosion. 13.1.3.2 Air quality: During the construction period, environmental supervision of air quality focuses on ensuring that the construction party implements effective measures to control dust generation. Monitoring parameters: Since dust is the main factor affecting air quality during excavation and transportation, the monitoring parameter designated is the total suspended particulate matter level (TSP); in addition, wind speed and direction are also monitored. Station location: The 24-hour TSP monitoring in the air is carried out near the main sensitive areas affected by construction activities; it is recommended that the specific monitoring sites be located 100 meters downwind from the construction sites within each construction area. Wind speed and direction data, used to determine the source of dust emissions, can be obtained directly from the local meteorological station. The placement of monitoring stations is ultimately constrained by objective factors such as the distance to power sources, the travel time for personnel, and safety considerations. Monitoring frequency and duration: One month prior to the official start of construction, baseline monitoring of average TSP levels should be carried out at the construction site and sensitive areas for 4 consecutive days, with three measurements per day. These results, along with the monitoring data from the environmental impact assessment, serve as the baseline before construction begins, to determine the air quality warning levels. Throughout the construction period, environmental monitoring stations should be commissioned to measure the 24-hour average TSP at each monitoring station every month, and portable dust meters should be used to measure the 1-hour average TSP for one day per week. Once the action level is exceeded, TSP monitoring for 1 hour, three days a week, must be conducted at a location 10 meters downwind outside the site boundaries of each construction site, until the average TSP level returns below the action level. Once the limit level is exceeded, and it is determined that this excess is caused by on-site construction, the monitoring frequency of TSP every 1 hour should be increased to once daily until the average TSP levels return below the limit level. 13.1.3.3 Noise: During the construction period, noise level monitoring is aimed at ensuring that the construction party implements effective measures to control noise, and monitoring activities are carried out to assess this. The parameter monitored is the equivalent sound level, and an integrated sound level meter of the AWA5610B model is used for such measurements. Location of the measurement point: The monitoring point is located 20 meters away from the construction site. Monitoring frequency and duration: Noise is monitored regularly throughout the entire construction period. 13.1.3.4 Other supervision tasks: (1) Supervise whether the construction unit restores the greenery while carrying out construction. (2) Whether the camp setup and material stacking are within the first-level protection area, and whether construction is carried out in accordance with the requirements of the report, etc. 13.2 Environmental management and monitoring of pumping stations: To strengthen supervision and management, pollution source monitoring should be carried out regularly as required. A separate environmental monitoring department is also established to be responsible for the regular monitoring of wastewater and waste gases on a daily basis. (1) Exhaust gas monitoring items and frequency: Monitoring target: Unorganized emissions within the factory area. Monitoring items: NH3, H2S, as well as other unorganized emission pollutants such as odors. Monitoring frequency: The indicator is monitored twice a year. Monitoring method: Comply with the monitoring requirements specified in the \"Methods for Monitoring and Analyzing Air and Exhaust Gases\" (prepared by the Environmental Protection Bureau). (3) Boundary noise monitoring: Based on the environmental conditions and operational status of the construction project, 4 noise measurement points are installed along the perimeter of the facility. Monitoring frequency: twice a year, once during the day and once at night. For those that do not have the conditions for self-monitoring, they can entrust specialized environmental monitoring agencies to carry out the monitoring. All staff members are trained and work with certificates; they strictly follow the operating procedures for managing waste materials, implement a job responsibility system, and maintain environmental protection records. After the project is put into operation, efforts should be made to establish a comprehensive environmental management system and monitoring system, managing it in accordance with the IS014000 environmental management standards and obtaining certification. Achieve full-process control over clean production, pollution prevention, and pollution treatment in order to obtain greater environmental benefits. The environmental protection facilities of a project should be designed, constructed, and put into use simultaneously with the production facilities.
