SS/2493 RTE Wildlife & Cover-type Mapping SECTION 1: INTRODUCTION 1.1 Background 1.1.1 General Description of the Relicensing Process Public Utility District No. 1 of Chelan County (hereinafter called Chelan PUD) owns and operates the Rocky Reach Hydroelectric Project (FERC No. 2145) located on the Columbia River in Chelan County, Washington, approximately seven miles upstream of the City of Wenatchee. The original license was granted for the Rocky Reach Project on July 11, 1957 by the Federal Power Commission, now the Federal Energy Regulatory Commission (FERC). This license expires on June 30, 2006. Chelan PUD intends to seek a new federal license to operate the Rocky Reach Project and has begun preparation for the process referred to as “relicensing”. The FERC relicensing process is based on laws and regulations that require years of extensive planning, including environmental studies, agency consultation, and public involvement. Chelan PUD has requested and received approval from FERC to employ an Alternative Relicensing Process for the Rocky Reach Project, as allowed under FERC’s Final Rule issued on October 29, 1997 (Docket No. RM95-16-000; Order No. 596). The Alternative Relicensing Process (ARP) proposed by Chelan PUD is intended to expedite the licensing process by combining the pre-filing consultation and environmental review processes into a single process, and by improving and facilitating communications among the participants in the licensing process. One of the first steps taken by Chelan PUD in the Rocky Reach Project ARP was to solicit identification of issues from the participating stakeholders
