s well as any environmental benefits that may result from the proposed action. Following the acceptance criteria listed above will help ensure that the environmental impacts of the transmission system on the aquatic environment will be considered with respect to matters covered by such standards and requirements. III. REVIEW PROCEDURES To evaluate the impacts to aquatic ecosystems from transmission facility operating and maintenance, the reviewer should take the following steps: (1) Identify operational and maintenance activities associated with transmission facilities and consider those that could adversely affect those “important” aquatic species and habitats identified by the reviewer for ESRP 2.4.2. ` The resources to be considered include marshlands, wetlands, impoundments, and water bodies. ` Potential impacts on these resources include heating of water bodies from removal of shade trees, siltation and turbidity resulting from increased runoff and erosion, runoff of defoliants and herbicides, recreational access by the public, and high energy electrical fields associated with underwater transmission facilities. (2) Consult with the reviewer for ESRP 5.2.1 for any needed hydrological data. When potential impacts are anticipated October 1999 5.6.2-5 NUREG-1555 ` inventory the “important” aquatic species or habitats vulnerable to the identified operation and maintenance practices ` predict the environmental impacts on these aquatic species and habitats. (3) Compare proposed transmission system operation and maintenance with the provisions of standards and guides pertinent to the operation and maintenance of transmission facilities and corridors. (4) Determine whether the proposed operation and maintenance procedures are those generally recognized as environmentally responsible. Following are examples of such procedures: ` maintaining ground cover in rights-of-way to avoid runoff and siltation ` avoiding the use of herbicides and defoliants near waterways
