REVIEW RESPONSIBILITIES Primary—Appendix B Secondary—Appendix B I. AREAS OF REVIEW This environmental standard review plan (ESRP) directs the staff’s identification, quantification, and evaluation of the impacts of transmission facility operation and maintenance on “important” aquatic species and habitats (defined in Table 2.4.2-1). The review should include consideration of the aquatic impacts of the operation and maintenance of transmission lines and corridors, substations, and switch- yards in sufficient detail to allow the reviewer to assess the magnitude of potential impacts. When adverse impacts of sufficient magnitude are identified, the reviewer should evaluate alternative operating and maintenance practices to mitigate or avoid environmental impacts. This review will be initiated only when the reviewer for ESRP 2.4.2 determines that there are aquatic environments that could be impacted by transmission system operation or maintenance. Review Interfaces The reviewer for this ESRP should obtain inputs from and provide inputs to reviewers for the following ESRPs, as indicated: ` ESRP 2.2.2. Obtain information about the transmission corridors and offsite areas in sufficient detail to determine where impacts to aquatic ecosystems from transmission system operation and maintenance could occur. NUREG-1555 5.6.2-2 October 1999 ` ESRP 2.4.2. Obtain information about unique aquatic habitats, including critical habitat for threatened and endangered species in the vicinity of the transmission corridors. ` ESRP 3.7. Obtain information regarding the physical characteristics of power transmission systems and maintenance procedures necessary for determining environmental impacts on the aquatic ecosystem. ` ESRP 4.3.2. Obtain information on impacts of transmission construction on aquatic resources. ` ESRP 5.2.1. Obtain a list of hydrological alterations that will take place along the transmission corridor and that could potentially impact the aquatic ecosystem. `
