1.4 Assessment Grade

1.4.1 Acoustic environment


At present, the airport link road-Airport Avenue line has not been determined, but the basic direction is fixed, only requiring some partial adjustment. The environmental impact assessment on airport avenue is included into environmental management framework. After preliminary site investigation, there are no special environmental sensitive points such as hospitals and sanatoriums on both sides along the road within 200m, and the main environmental sensitive points are mainly urban residential areas. According to the principle related to classification of evaluation grade of Technical Guidelines for Environmental Impact Assessment (Sound Environment) (HJ2.4-2008), the traffic noise is evaluated as Grade II. Once the line is determined finally, EIA staff will conduct detailed site survey, once the special environment sensitive points are found on the two sides along the road 200m range. It will classify the EIA grade in accordance with the requirements of environmental management framework.

1.4.2Ambient Air


The pollution sources of ambient air mainly come from the boiler flue gas, aircraft exhaust, and car exhaust. Aircraft exhaust and car exhaust are fugitive emissions. The boiler adopts clean energy-natural gas as raw material. Estimating the pollutant emissions by the emission factors, SO2 emissions is 0.012kg/h and NOx emissions is 0.118 kg/h, after estimation and calculation, Pmax=6.47%, less than 10%. Class 1 Ambient Air Quality Functional Zone is not included in the assessment scope, the environmental quality of the major assessment factors does not approach or exceed the environmental quality standards, this project does not emit special pollutants that will do harm to human health or seriously affect ecological environment. According to “Technical Guidelines for Environmental Impact Assessment-Atmospheric Environment” (HJ2.2-2008), the Ambient Air of this project is rated as Grade Three.

1.4.3 Surface water environment


The sewage generated by the project is treated in the site by the sewage treatment state and recycled completely without discharge. For impact on surface water environment, carry out the demonstration analysis on sewage without discharge and the impact of airport construction on the basin water quality as well as the impact on water for agricultural irrigation.

1.4.4 Ground Water Environment


According to the classification and rating standard of construction projects classification and assessment grade in “Technical Guidelines for Environmental Impact Assessment Ground Water Environment” (HJ610-2011), and by taking the airport engineering characteristics into account, project Ground Water environment impact is rated as Grade Three. Specific assessment basis is show in table 1-4-1.

1.4.5 Terrestrial Ecological Environment


The airport project newly acquired 148.8hm2 of land, the Airport Avenue acquired 27.8 hm2 of land, supporting pipelines and drainage works do not cover permanent area of land, the land acquisition aread of the project is less than 2km2 , and the project does not involve the ecologically sensitive areas like the Natural Reserve, the World Cultural and Natural Heritage Sites and etc.. The World’s natural heritage Sanqing Mountain is about 60km away from the airport in stright-line distance. According to the relevant assessment grade evaluation principles and methods of “Technical Guidelines for Environmental Impact Assessment-Ecological Impact” (HJ19-2011), the ecological assessment grade is identified as Grade Three.

1.4.6 Environmental Risk Assessment


According to “Identificaiton of Major Hazard Sources of Hazard Chemicals” (GB18218-2009), the major hazard unit of the airport is the Airport Depot, Ground Gas Station and Sewage Treatment Station. Comparing the critial mass of the various risk aspects of hazard substances with the actual storage capacity, the hazard units of the airport do not constitue a major hazard source, therefore, it is rated as Grade Two.

Airport avenue project

The area along the project road belongs to insensitive area of ecological environment without key environmental protection objects including natural reserves or cultural relics preservation, which is thus evaluated as Grade III.

There are no special sensitive points such as hospitals and sanatoriums within the scope at 200m from both sides along the road, and main environmental sensitive point is town residence area, which is thus evaluated as Grade II.

The project road does not cross surface water region, and the discharge quantity of sewage during construction period for road construction is small. Thus, the evaluation for surface is determined as Grade III.

The evaluation scope does not include Category I ambient air quality function area and the ambient quality of the main evaluation factor is not close to or beyond the standard for ambient quality. The project does not emit the special pollutants that are greatly harmful to human body health or ecological environment; the evaluation of ambient air of the project is Grade III.

Pipeline project

The impact during construction period mainly includes vegetation damage, occupancy; the evaluation grade is Grade III.

After construction of project, the functional area belongs to Category II Standard area regulated by GB3096-2008. Its impact on acoustic environment is mainly reflected during construction period and the impact of noise during the construction period will disappear with the ending of construction period. Considering the degree of the affected people comprehensively, the evaluation for sound environment is determined as Grade III.

The project is newly constructing sewage, water supply, air supply net of 4521.212m and aviation fuel transportation, which does not cause negative impact on the water environment during the operation. Judging from HJ/T2.3-93, the evaluation grade of surface water is determined as Grade III.

The impact of the project on the atmosphere is mainly reflected in construction period. Pollutants are mainly the construction dusts, the type of generated atmosphere pollutant is simple and the affected area is limited. According to judgment requirement of guidelines, the impact evaluation of atmosphere environment of the project is determined as Grade III.
