1. Analysis of the importance of environmental monitoring in environmental impact assessment

1.1 Overview of environmental monitoring

Environmental monitoring is to use advanced technical means to understand the environmental changes of regional environmental targets, and to monitor and analyze the trend of environmental changes with ultra-low emission dust meter. Environmental monitoring is a very important part of the current environmental management work. Environmental monitoring involves the knowledge of many disciplines such as physics and biochemistry, and the content is complex. Therefore, relevant knowledge should be flexibly applied in the qualitative and quantitative analysis of environmental monitoring, so as to provide more valuable data for later environmental impact assessment.

1.2 Overview of environmental impact assessment

Environmental impact assessment is mainly to analyze the impact factors of environmental objectives, predict and evaluate the development trend of environmental changes, and provide a very valuable reference for later environmental protection and environmental governance. In the current environmental situation, the EIA should not only carry out the tracking assessment for specific environmental objectives, but also ensure the timeliness and dynamic change characteristics of the environmental assessment, so as to make the environmental assessment scheme more practical and avoid interference for the later environmental protection and environmental governance. In order to promote the sustainable development of social environment, the specific environmental impact assessment involves air, solid pollutants, water source pollution, noise pollution and other aspects.

1.3 Analysis of the importance of environmental monitoring in environmental impact assessment

In order to give full play to the role of environmental monitoring in environmental impact assessment and obtain more accurate and reliable environmental impact assessment results, environmental monitoring personnel need to have a certain understanding of environmental objectives and be able to have a certain grasp of the different change processes of environmental objectives. This is not only the main content of environmental monitoring, but also the way to play the core value of environmental monitoring. The main values of environmental monitoring in environmental impact assessment are as follows. ① Ensure that the environmental impact assessment can obtain more accurate and reliable results. The preparation of EIA report must ensure the reliability of relevant data and be able to truly reflect the environmental changes, so as to fully reduce the errors in the assessment process and effectively improve the actual effect of EIA. For example, after the analysis of environmental quality, carrying capacity, capacity and other indicators in the environmental monitoring process, the accurately obtained data can provide a very valuable reference for the preparation of the environmental impact assessment report. ② The ultimate goal of the environmental impact assessment is to effectively promote the environmental pollution control. The ultra-low CEMS system and the environmental monitoring work can effectively inspect the implementation effect of environmental protection measures, which greatly promotes the improvement of the environmental pollution control effect.

The preparation of the environmental impact assessment plan can only be carried out after sufficient reference to the relevant data. In this process, the relevant personnel should standardize the operation process and take reasonable measures, so as to effectively avoid the occurrence of hidden dangers for environmental pollution control due to deviations in the assessment process. Therefore, the environmental impact assessment process should be scientific Reasonable use of environmental monitoring means can effectively promote the environmental governance and environmental protection work schedule. At the same time, we should strengthen the innovation and optimization of environmental monitoring technology, so as to constantly improve the environmental quality.

2 Supporting role of environmental monitoring for environmental impact assessment

2.1 Carry out environmental quality status assessment for the proposed project area

In order to show the actual situation and development trend of the environmental quality in the monitoring area more comprehensively, timely and accurately, it is necessary to carry out environmental monitoring to provide more reliable reference for environmental pollution control, environmental management and planning. When carrying out the environmental impact assessment on the proposed project, the actual environmental quality shall be investigated, monitored and assessed first to provide reference for the follow-up work.

2.2 Setting up the general monitoring scheme for the proposed project area

The environmental impact assessment report of the proposed construction project needs to clarify the importance of the environmental monitoring plan. After investigating the basic environmental data, people need to fully understand the hydrological environment, contact the meteorological data, set up a conventional monitoring scheme for the proposed project area, and define the monitoring contents.

2.3 Avoid disasters and pollution caused by the proposed project

According to the environmental monitoring plan in the environmental impact assessment report of the proposed construction project, people can prevent the disasters or pollution accidents caused by the project during construction, so that the regional environmental quality can be controlled.

2.4 Provide services for the completion acceptance of the proposed construction project

When the proposed construction project is completed and the acceptance work is carried out, people need to use environmental monitoring to verify whether the environmental quality of the project area and nearby areas can meet the environmental requirements, and ensure that the requirements of the environmental impact statement can be met. If the acceptance results cannot meet the environmental protection indicators or the requirements of the environmental impact report, the acceptance work cannot be passed.

3 Suggestions on Environmental Monitoring

3.1 Strengthen the review of the qualification and capacity of monitoring units

At this stage, the monitoring unit needs to have sufficient monitoring capacity, the monitoring personnel need to have the work license for monitoring projects, and the annex to the environmental impact report needs to include the measurement certification certificate and the monitoring capacity form of the monitoring unit, and it needs to be affixed with the official seal of the relevant department. For special factors, if the monitoring unit has the ability to monitor but cannot obtain metrological certification, the monitoring report needs to write non metrological certification items so that people can make judgments according to the actual situation. The report shall indicate the historical data used, and the monitoring report and qualification certificate of the monitoring unit shall be attached. For major construction projects or planned projects, the environmental monitoring department selects designated personnel to carry out supervision on the site and in the laboratory. If there is any doubt about the data, the monitoring unit is required to provide relevant records.

3.2 Improve relevant laws and regulations and clarify responsibilities

At this stage, China's laws and regulations on environmental protection are not perfect enough, and it is difficult to effectively use laws and regulations to regulate the relevant behaviors of monitoring units. Although there are relevant provisions in some regulations, the punishment methods are not specific and strict enough. It is difficult to investigate civil and criminal liability for providing false data. Therefore, the state needs to improve relevant laws and regulations in a timely manner and clarify responsibilities so that environmental monitoring departments and environmental assessment departments can act in accordance with the law, thus enhancing the authenticity and representativeness of data.

3.3 Establish and improve the external supervision and management system

At this stage, the monitoring data is an important part of the environmental impact assessment results, and the monitoring personnel need to contact the project approval department. Therefore, when reviewing the environmental assessment report, it is necessary to strictly check the rationality of the current monitoring data and hire environmental monitoring experts to jointly review, so as to strengthen the supervision and management of monitoring data. When carrying out metrological certification and laboratory accreditation, it is necessary to ensure the comprehensiveness and fairness of the on-site review, and it is necessary to carry out supervision review and regular review on the units that have obtained certification or accreditation certificates, so as to maintain the continuity of qualification management, ensure the authority and credibility of metrological certification and national accreditation of laboratories, and match the qualifications and capabilities.

3.4 Strengthen the training of environmental monitoring technicians

Improve the ability and quality of environmental monitoring technicians, and regularly carry out personnel training and education. The VOCs online monitoring system promotes monitoring technicians to master the use specifications of various equipment to ensure the smooth progress of monitoring. For large monitoring equipment, special supporting personnel shall be provided to enable technicians to meet the needs of monitoring work and give full play to the application value of monitoring technicians.

4 Conclusion

To sum up, with the constant acceleration of industrial development, the environment on which we live has been greatly affected. Environmental monitoring is an important basis for environmental impact assessment, but there are a series of problems in the current monitoring work. In this case, we should actively take a series of effective measures to constantly improve the environmental monitoring work and make the monitoring data more scientific and accurate, so that the environmental impact assessment can play a more active role.
