INTRODUCTION 1.1 Background The Inner Ring Road (IRR), an express roadway planned to circle the city center of Guangzhou Municipality, is the most important element for improving transport in the city center areas. It will lead traffic away from the city center and play an important role in urban economic development. This project was the subject of an Environmental Assessment (EA) which was required and reviewed by both the National Environmental Protection Agency (NEPA) and the World Bank. The EA Report concluded that the proposed Inner Ring Road project will assist in providing a solution to traffic congestion in the city center, improve the quality of urban life and stimulate economic development It was noted that the project will result in degradation of environmental quality to some extent in the immediate vicinity, but will make a positive contribution to pollution control in the overall urban area, especially in the city center. The prime purpose of the Enviromnental Action Plan (EAP) is to ensure that the recommended mitigation measures were implemented effectively. The project was judged to be environmentally feasible if the recommended mitigation measures for particular road sections were selected. The project also allows for the opportuiity to enhance the enviromnental conditions in the city center through longer term solutions such as traffic management, urban planning and implementing the various components of the Proposal for Vehicle Emission Control Research. Project Overview The proposed IRR (Figure 1.1-1) is 26.7 kn in length and approximately 90% of it consists of an elevated viaduct. Ground level sections are proposed along Liuersan Rd. and adjacent to the Guangzho.u Zoo. The alignrment (description follows a clockwise direction beginning at Liuersan Rd.) goes from the Shamian Island area of the city which is known for its cultural importance, along Liuersan Rd. and heads northward along the existing alignment of Huangsha Rd. and Nanan Rd. towards the Guangzhou Railway StatiorL East of the station the alignment follows Hengfu Rd. to the north. A new aligrunent to the south borders the Guangzhou Zoo for approximately 500 m and contnues south until it joins with Zongshan Rd. From there it curves to the west until the alignment divides north of the Pearl River. The two alignments (Donghu Rd. and Donghua Rd. S.) cross the Pearl River via the Haiyin Bridge and the Jiangwan Bridge (currently under construction) respectively. The two alignments rejoin on the south side of the Pearl River and will follow a new alignment along the proposed Nantian Rd. westward until it intersects with Industry Ave. and Hongde Rd. The aligmnent follows Hongde Rd. northward across the Pearl River via the Renmin Bridge, joining Liuersan Rd. on the north side of the river.

These facts and the number of potential sensitive receptors (educational, recreational and institutional buildings) which have been identified along the alignment presents a number of difficulties for effectively mitigating potential impacts. The road will be widened from existing widths (16-50 m) to a proposed width of 50 m. The number of lanes varies but generally consists of two- or three- lanes of traffic traveling in each direction. A new bridge structure will be required adjacent to the Renmin Bridge. The proposed alignment has 12 interchanges and 12 double-ramps. Average distance between interchanges is 1.5 km, with a minimum of 850 m; and the minimum distance between ramps is 345 m which is suitable for the designed traffic speed of 50 - 60 km/h. As part of the Environmental Assessment of the project there were a number of altemative alignments evaluated. Issues and concerns were addressed during the route selection process to minimize or reduce many of the potential adverse biophysical and socioeconomic impacts associated with the project. 1.2 Objectives As indicated above, the EA Report identified that the major environmental effects relate to noise and air quality. There are some landscape changes and sunshine obstruction occurrences at a few locations due to elevated road sections. Of the two major factors, the effective control of urban motor vehicle pollution will require a number of citywide strategies and countermeasures. These are summarized in this EAP (Section 2.3.3) and are more completely described in the Proposal for Vehicle Emission Control Research, a separate document related to the Enviromnental Component of the Guangzhou City Center Transport Project. This EAP identifies measures to minimize impacts during Design of the project as well as site-specific mitigation measures to be implemented during both Construction and Operation. This EAP provides the framework for the implementation of mitigation measures and environmental management and monitoring during the construction and operation of the project. This document details all commitments made in the EA Report and can be used as a reference document to ensure all environmental protection measures are implemented. An Environmental Action Plan: Identifies site-specific miligation measures Representatives of the EA team, Project Office and Design Team conducted field investigations at each of the sensitive points and proposed appropriate site specific engineering and managerial mitigation measures as identified during the EA process. These measures should be technically eftective and economically feasible. It is essential that these measures be provided to project designers in sufficient detail to ensure the contractors incorporate costs for mitigation. September 1997 2  GUANGZFHOU IRR ENVIRONMENTAL ACTMON PLAN * Provides an exclusive documentfor project implementation The EAP is one of the documents for the World Bank to appraise the project and provide a single source of environmental information for contractors, inspectors and others associated with the project during construction and operation. * Identifies institutional roles and responsibilities The roles and responsibilities of the various institutions and regulatory agencies are identified as well as proposed lines of communication and reporting relationships. * Outlines environmental monitoring during construction and operation phases The EAP identifies requirements related to the monitoring program. Environmental monitoring is undertaken during both the construction and operation phases to ensure the effectiveness of mitigation measures, to respond to unanticipated environmental concerns at an early stage and to determine the accuracy of impact predictions. 1.3 ROLES AND RESPONSIBILITIES OF VARIOUS INSTITUTIONS 1.3.1 Legal Basis for Enforcement The EAP was prepared based on the results of the Environmental Assessment (EA) Report prepared for the project.
