3.9 Mixing zone

Pollutant emission standards to the ocean after dilution diffusion reaches the surrounding marine environment quality standards occupied sea area.

NOTE. The outlet center, after dilution and diffusion of pollutants in order to achieve the environmental quality standards in waters around the maximum distance for the area of a circle radius indicated.

4.1 Environmental Impact Assessment of the results of marine engineering

Environmental impact assessment of the results of marine construction projects including environmental impact report and environmental impact statement.

Belong to Level 1, Level 2 and Level 3 evaluation level of marine construction projects and large marine construction projects, marine engineering should be prepared ring

Environmental impact report. Marine engineering preparation of an environmental impact report should be consistent with the requirements of Appendix A.

Contents of the report should be clear, clear, concise; wherein the state of the environment can be based on marine survey and monitoring data, the data given in the summary table and evaluation

Summary index briefly clarify the status of environmental evaluation of water quality, sediment quality and biological quality of the results; environmental impact analysis and forecast content

Should be concise, focused, avoid theory, common sense, explanatory help content.

Rank less than three marine construction projects, marine engineering can prepare environmental impact statement. Marine Environmental Impact newspaper

Table for the report shall comply with Appendix B requirements.

4.2 marine engineering environmental impact assessment stage

Environmental impact assessment of marine engineering generally be divided into three stages (see Figure 1). Preparation of environmental impact statements of construction projects can be simple

Evaluation sessions.

a) The first stage is the preparation stage, the main tasks include.

--- Research on environmental protection and management laws, regulations and policies, research and other documents related to the environmental impact assessment;

--- Collect historical data, state of the environment to carry out reconnaissance, conduct a preliminary analysis of construction projects;

--- Determine the individual level of environmental impact assessment and evaluation of the evaluation level of construction projects, specifically within the construction project environmental impact assessment

Content, scope of the evaluation, the evaluation criteria;

--- Distil the main elements of the environmental impact, environmentally sensitive goals and environmental objectives;

--- Clear state of the environment survey content, the scope of investigation, survey items (elements or factors), survey stations laid, the investigation period, the investigation

Frequency, analysis and detection methods, evaluation methods, technical standards, etc. to be executed;

--- Screening to determine the main factors of environmental impact assessment and evaluation factor;

--- Clear the next phase of the environmental impact assessment of the key elements and environmental impact of the main contents of the report and so on.

b) The second stage is the formal sessions, the main tasks include.

--- Carry out detailed engineering analysis;

--- According to the environmental assessment has clearly content, scope and focus of the evaluation project evaluation, organization and implementation of environmental and public participation Survey survey;

--- Based on environmental quality requirements, analyze the obtained data, information, carrying out environmental situation analysis, evaluation of the evaluation;

--- Carry out the analysis of environmental impact prediction, evaluation;

--- Carry out clean production, environmental risks, the total control of the analysis and evaluation.

c) The third stage is the preparation of the report or report form stage, the main tasks include.

--- Based Environmental Investigation and forecasting analysis, environmental quality in accordance with the requirements set forth loop construction project site, size and layout

Environmental feasibility analysis, evaluation findings;

--- Give environmental protection concrete countermeasures and suggestions;

--- Clarify environmental management and monitoring plan.

4.3 marine environmental impact assessment program of work

Class 1 evaluation level of marine construction projects and large marine construction project, the project should compile a marine EIA Price of the program of work, the specific content and format shall conform to Annex C requirements.

Marine environmental impact assessment program of work should be based on a preliminary understanding of the engineering characteristics and environmental characteristics, determination and clear construction projects

The scope of the environmental impact assessment, evaluation level, evaluation criteria, the main environmental issues, objectives and key environmental protection environmentally sensitive objects; preliminary determination

Evaluation of content, evaluation priorities; determine the environmental status of the survey content, the scope of investigation, survey items (elements or factors), survey stations layout, survey

Period, the frequency of the survey, analysis and detection methods, evaluation methods, technical standards should perform technical evaluation methods and routes; preparation guide ring

Environmental impact evaluation of the implementation of the program.
