In addition, WS could occasionally receive requests for assistance with feral or free-ranging non-native mammals2. The Tennessee Valley Authority (TVA) also continues to experience damage and threats of damage associated with mammals at facilities or properties they own or manage in Georgia. The TVA could request the assistance of WS to manage damage or threats of damage at those facilities and properties. Individual damage management projects conducted by the WS program could be categorically excluded from further analysis under the National Environmental Policy Act (NEPA), in accordance with APHIS implementing regulations for the NEPA (7 CFR 372.5(c), 60 FR 6000-6003). The purpose of this Environmental Assessment (EA) is to evaluate cumulatively the individual projects that WS could conduct to manage damage and threats to agricultural resources, property, natural resources, and threats to people caused by those mammal species identified previously, including those activities that the TVA could request of WS. This EA will assist in determining if the proposed cumulative management of mammal damage could have a significant impact on the environment based on previous activities conducted by WS and based on the anticipation of conducting additional efforts to manage damage caused by those species. Because the goal of WS would be to conduct a coordinated program to alleviate mammal damage in accordance with plans, goals, and objectives developed to reduce damage, and because the program’s goals and directives3 would be to provide assistance when requested, within the constraints of available funding and workforce, it is conceivable that additional damage management efforts could occur. Thus, this EA anticipates those additional efforts and the analyses would apply to actions that may occur in any locale and at any time within Georgia as part of a coordinated program. This EA analyzes the potential effects of mammal damage management when requested, as coordinated between WS, the TVA, and the Georgia Department of Natural Resources (GDNR). WS and the TVA are preparing this EA to 1) facilitate planning; 2) promote interagency coordination; 3) streamline program management; 4) clearly communicate to the public the analysis of individual and cumulative impacts of proposed activities; and 5) evaluate and determine if there would be any potentially significant or cumulative effects from the alternative approaches developed to meet the need for action. 1The WS program is authorized to protect agriculture and other resources from damage caused by wildlife through the Act of March 2, 1931 (46 Stat. 1468; 7 USC 426-426b) as amended, and the Act of December 22, 1987 (101 Stat. 1329-331, 7 USC 426c). 2 See further discussion in Chapter 4, Section 4.1. 3At the time of preparation, WS’ Directives occurred at the following web address: http://www.aphis.usda.gov/wildlife_damage/ws_directives.shtml. 1 The analyses contained in this EA are based on information derived from WS’ Management Information System, published documents (see Appendix A), interagency consultations, and public involvement. This EA evaluates the need for action to manage damage associated with mammals in the State, the potential issues associated with managing damage, and the environmental consequences of conducting different alternatives to meet the need for action while addressing the identified issues. WS, in cooperation with the TVA, initially developed the issues and alternatives associated with managing damage caused by mammals
