General 1.1 Background Liaoning, located in the northeast of China, is a key industry base in the country. Shenyang, Panjin, and Fushun to be covered by the Liao River Basin Project (LRBP) are relatively prosperous cities in the province. However, environmental issues, especially municipal wastewater treatment, have been ignored for decades in Liaoning. Up to now, there is only one operating municipal wastewater treatment plant and limited industrial treatment capacity. It is estimated that total untreated wastewater from point-source in liaoning reaches 2.1 billion tons per annum, containing over 643,000 tons of Chemical Oxygen Demand. As a result, all of the river sections within cities in Liaoning exceed Category V of surface water quality standard in China, the bottom- line standard classified for beneficial use, putting millions of people at health risk. In 1998, Liaoning Provincial Government has prepared a profound environment clean up plan-" Ninth-five Year Plan and 2010 Long-term Program for Water Pollution Control and Abatement in Liao River Basin" and has been approved by the State Council. Meanwhile, State Council has identified Liao River Basin as one component in the " Three Rivers and Three Lakes" which are badly polluted and given urgent top priority for wastewater treatment. 1.2 EIA Progress In accordance with national and WB policies, Liaoning Provincial Government has requested the WB for bilateral support for LRBP. Since July 2001, the World Bank mission has visited Liaoning for several times to discuss with Liaoning Government to provide guidance for project preparation. The city-level Environment Impact Assessment (EIA) Reports has been completed in accordance with national standard and the World Bank's requirements. On such basis, a basin- wide EIA report has been prepared by Liaoning Provincial Scientific Research Institute for Environment Protection in accordance with national standard for international financial organization financed project and the Operational Directive (January 1999 edition) of the Bank. 1.3 Basis for preparation of EIA and Environment Management Plan (EMP) * Water pollution control and abatement law of P .R.

Objective of EMP The EMP is an integral part of the project EIA. It consists of the set of mitigation, monitoring and institutional measures to be taken during implementation and operation to eliminate adverse environmental and social impacts, offset them, or reduce them to acceptable levels. 3. Overview of the project 3.1 Components of the project The LRBP 2 consists of construction of sewerage interceptor and WwTP in three cities-Shenyang, Panjin, and Fushun. Following Table 3-1 gives the details of the components of LRBP 2.

The predicted intensity of odor source in the four WwTPs is presented in the following Table 4-3.

It consists of grits, screenings and waste activated sludge. Table 4-4 gives the details of the sludge to be produced in the WwTPs.

Based on comparative analysis with the operating WwTP in China, the intensity of noise at the point one meter from the equipment has been predicted and shown in Table 4-6. Table 4-6 Predicted noise in the four WwTp and pumping stations No. Equipment Leg [dB(A)I I Wastewater lifting pump 95 2 Blower (for aeration tank) 115 3 Blower (for bio-reactor) 95 4 Sludge dewatering machine 85 5 Sludge pump 92 6 Air compressor 92 7 Scriper 90 In construction phase, the intensity of noise varies according to the types of construction machines, operation time and terrain. Table 4-7 shows the noise intensity of major construction equipment.

The measured noise values are more than 90 dB(A) and 85 dB(A) respectively. Separate insulation chamber is proposed to accommodate the equipment. The predicted noise values are therefore to be 65 dB(A) and 55 dB(A) respectively, which can meet 6 February 2002  Seconid Liao River Basi,, Project Environm,ent 'la,,ageietit Plan the Class III standard in the - Noise Standard for Industrial Plant Boundary" (GB 12348-90). 4.3.4 Spoil It is determined that large quantity of earth will be required for site leveling due to high designed elevation. However the unappropriate management of spoil would cause soil erosion of primary concem. The digging activity for both pipeline and plant site will generate spoil in various quantity and location. A dedicated storage site for spoil would be constructed and maintained near the plant site by constructor, with drainage structure and punching equipment, or the spoil be transported to a site designated by local environmental agency. Timely cleaning, backfiring, compacting to a stabilization angle and transporting of spoil would be taken by constructor to minimize or avoid the spoil impact. 4.3.5 Traffic During construction phase, the local traffic condition will be adversely impacted by increased traffic flow due to construction vehicles and traffic interruption due to road excavation. 4.3.6 Land occupation and resettlement The project will occupy land both temporarily and permanently. The proposed WwTP and pumping station will occupy land permanently and construction of pipeline will occupy land temporarily. Following Table 4-8 gives the summary of land occupation in the four project cities.

The project construction work also will bring adverse impact in temns of land occupation and vegetation reduction. According to environmental, economic and technical conditions in the project cities, the proposed altemative mitigation measures and the potential scope of impact, specific countermeasures has been developed for these cities. Details are listed in the table 5-1.
