5050.4 3/21/80 (c) If the proposal would affect water resources (i.e., wetlands; groundwater; impoundment, diversion, deepening, controlling, modifying, pollut- ing, dredging, or filling of any stream or other body of water), the Fish and Wildlife Coordination Act applies. Consultation is to be initiated with the U.S. Fish and Wildlife Service and with the state agency having administration over wildlife resources. Letters are to be obtained from the Fish and Wildlife Service and the state agency on the wildlife aspects of the proposal for the purposes of determining the possible damage to wildlife resources and of determining means and measures that should be adopted to prevent the loss of or damage to wildlife resources as well as to provide concurrently for the development and improvement of such resources. 1 If the letters from the Fish and Wildlife Service and the state agency indicate substantial damage to wildlife attributable to the proposal which will not be mitigated to a minimal level, the proposal is considered to be one with potential significant impacts. Further evaluation shall be performed under FAA direction as described in paragraph 85i. 2 If the letters from the Fish and Wildlife Service and the state agency indicate only minimal impacts, it may be assumed that there would be no significant impact on biotic communities. The environmental assessment shall include the letters from the Fish and Wildlife Service and the state agency and shall also include such justifiable means and measures to mitigate wildlife impacts as should be adopted to obtain maximum overall project benefits. No further analysis as described below is needed. (d) If the proposal would not affect water resources as described in subparagraph (c) above, the Fish and Wildlife Coordination Act does not apply. In this case, a series of thresholds are to be examined to determine if there is the potential for significant impact on biotic communi- ties. The four subparagraphs below should be reviewed in the order given to determine which one applies to the proposal; e.g., if subparagraph 1 applies, the remainder do not and no further analysis is needed. 1 If the proposal would impact only man -dominated areas such as previously disturbed airport property, populated areas, or farmland, it may be assumed that there would be no significant impact on biotic communities. 2 If the proposal would impact other than man -dominated areas but the impacts would primarily be transient rather than permanent, such as dislocation or other impacts due to construction activities, it may be assumed that there would be no significant impact on biotic communities. The environmental assessment shall document the transient nature of the impacts and any mitigation measures. Mitigation measures may include: and aquatic communities.
