Basis for EIA Preparation



      1. Laws and Regulations

During the preparation of environmental assessment, all relevant regulatory, policy, and administrative requirements – both at state and provincial levels – were followed, as were the World Bank’s ten safeguard policies. Major laws and regulations applied in the EA are as follows:




  • Laws of Environmental Protection of the PRC of December 26, 1989

  • Law of Air Pollution Control of the PRC of September 1, 2000

  • Law of Water Pollution Control of the PRC of May 15, 1996

  • Law of Environmental Noise Pollution Control of the PRC of March 1, 1997

  • Law of Cultural Relics Protection of the PRC of October 28, 2002

  • Management Regulations on Environmental Protection for Construction Projects of November 18, 1998

  • Circulation on Strengthening EIA for Construction Projects Receiving International Financing of 1993

  • Technical Specifications for Environmental Impact Assessment

  • Regulations on Establishment of Geological Natural Reserve, 1987

  • Regulations of Cultural Protection in Guizhou Province, 2005

  • The Principles for Conservation of Heritage Sites in China


      1. Documents

A number of documents include feasibility study reports for various project components, as well as expert and government officials’ opinions in the screening stage. The main documents that have been reviewed and used in the EA are:




  • Guizhou Provincial Tourism Development Master Plan, World Tourism Organization, China National Tourism Administration and Guizhou Provincial Tourism Administration, 2002

  • Guizhou Rural Tourism Development Plan, Guizhou Provincial Research and Communication Center for Cultural Tourism, 2006

  • Guizhou Eleventh Five Year Socio-economic Plan

  • Feasibility Study Reports for Each Component

  • Master Plan for each component area

  • Strategic Environmental Assessment Study, ERM

As the size of each component is very small, the Guizhou Provincial EPB requires that a consolidated EIA report be prepared for the project and that approval of the report be obtained.



      1. Screening of World Bank’s Safeguard Policies

The World Bank requirements include Operational Policies (OP), Best Procedure (BP), Good Practice (GP) and Operational Directives (OD), as well as the Bank’s standard list of ten safeguard policies. These ten are:




  • Environmental Assessment (OP/BP/GP4.01);

  • Forestry (OP/GP4.36);

  • Natural Habitats (OP/BP4.04);

  • Safety of Dams (OP/BP4.37);

  • Pest Management (OP4.09);

  • Involuntary Resettlement (OP4.12);

  • Indigenous People (OD4.20);

  • Cultural Property (OP4.11);

  • Projects in Disputed Areas (OP/BP/GP7.60); and

  • Projects on International Waterways (OP/BP/GP7.50).

Of these safeguard policies, Environmental Assessment (OP 4.01) is the primary requirement and thus the focus of this report. In addition, policies on Involuntary Resettlement (OP4.12), and Cultural Property (OP4.11) will be applied in the EA – at the very least during the screening stage or fully, if they are triggered.



    1. Applicable Standards
