INTRODUCTION 1.1 Overview 1. This document is the Initial Environmental Examination for the Tranche 3 Extension sub-projects of Peshawar Electricity Supply Company (PESCO). This IEE was prepared under Asian Development Bank (ADB) Power Distribution and Enhancement Multi-tranche Finance Facility (PDEMFF). 2. Government of the Islamic Republic of Pakistan (GoP) has requested ADB to provide the PDEMFF to facilitate investments in power distribution and development of networks of eight independent distribution companies (DISCOs) that distribute power to end user consumers. The funding from ADB is expected to be released in stages (tranches). The Power Distribution Enhancement (PDE) Investment Program is part of the GoP long term energy security strategy. The proposed ADB intervention will finance new investments in PDE and assist capacity building of sector related agencies. The investment program will cover necessary PDE development activities in secondary transmission/distribution networks of eight DISCOs and the PDEMFF loan is proposed to be approved by ADB in 2008. The PDEMFF activities include extension (additional transformers) and augmentation (replacement of transformers with higher capacity) distribution line extensions, new and replacement distribution lines, additional sub-stations, transformer protection and other non-network activities such as automatic meter reading, construction equipment and computerized accounting. New distribution lines to and from various network facilities and some of the above activities will also be included in the later tranches.

This IEE presents the results and conclusions of environmental assessment for the five (05) extension sub-projects proposed by PESCO and are submitted by Pakistan Electric Power Company (PEPCO) on behalf of PESCO. PEPCO has Page 2 of 71 Power Distribution Enhancement Project Tranche – 3, Peshawar Electric Supply Company Power Transformer Extension Subprojects Initial Environmental Examination been nominated by Ministry of Water and Power (MOWP) to act as the Executing Agency (EA) with each DISCO being the Implementing Agency (IA) for work in its own area. PEPCO‟s role in the processing and implementation of the investment program is that of a coordinator of such activities as preparation of PC-1s and PFRs, monitoring implementation activities; that includes submission of environmental assessments for all sub-projects in all tranches of the PDEMFF under ADB operating procedures. An IEE has been carried out to fulfill the requirements of ADB Safeguards Policy Statement, 200912. This IEE study report is used to complete the Initial Environmental Examination (IEE) for disclosure by ADB if necessary. 1 Initial project classification was carried out in 2006 and the Category is B. Most of the construction impacts will take place with only local impacts and there are no potential significant environmental impacts associated with the T3(tranche 3) sub- project construction. Initial environmental reconnaissance and REA carried out by consultants under ADB guidelines in May 2007 indicated that all the T2 sub-projects will be Category B. 2 ADB Safeguards policy Statement, 2009 Page 3 of 71 Power Distribution Enhancement Project Tranche – 3, Peshawar Electric Supply Company Power Transformer Extension Subprojects Initial Environmental Examination Page 4 of 71 Power Distribution Enhancement Project Tranche – 3, Peshawar Electric Supply Company Power Transformer Extension Subprojects Initial Environmental Examination Requirements for environmental assessment 4. Under the MFF loan procedures of ADB, implementation of safeguards is to be achieved by environmental assessment of every sub-project to be undertaken following ADB Safeguards Policy Statement, 2009. Power distribution enhancement and development type projects, that are limited to expansion of already developed facilities, have typically been classified as Category B. Each sub-project as been subject to environmental assessment after categorisation and the focus was on the most significant issues. 5. Under GoP regulations, the Pakistan Environmental Protection Agency Review of Initial Environmental Examination and Environmental Impact Assessment Regulations (2000) categorizes development projects into two schedules according to their potential environmental impact. The proponents of projects that have reasonably foreseeable impacts are required to submit an IEE for their respective projects (Schedule I). 6. Projects that have more adverse environmental impact (Schedule II) are required to submit
