or maintaining NAAQS as a revision to its SIP. Direct emissions are those emissions caused by or initiated by the Federal action that occur at the same time and place as the action. Indirect emissions are those caused by the Federal action that occur later in time or are located away from the action itself. Only those direct and indirect emissions that are reasonably foreseeable and that the Federal agency can practicably control need be considered. It must also be possible to locate and quantify direct and indirect emissions at the time a conformity determination is made. The Federal agency is not obligated to account for possible emissions that might result from the Federal action but cannot be specifically identified, quantified, or located. 5 Note that the final rule issued by EPA implementing the new statutory requirements for this provision (58 FR 63214) only requires that Federal agencies prepare a written conformity analysis and determination for proposed actions in NAAQS nonattainment or maintenance areas. However, proposed actions near nonattainment or maintenance areas may also cause or contribute to nonattainment. Therefore, 10 CFR 51.53(c)(3)(ii)(F) states that the ER should address this issue for facilities located either in or near a nonattainment or maintenance area, and EPA has indicated that in the future it may revise the rule similarly. This approach reflects the reality that emissions continue beyond geographical boundaries and is consistent with environmental impact assessments prepared in accordance with NEPA.

The ER should identify the erosion potential of site soils and describe best management practices to control erosion and runoff associated with continued plant operations and refurbishment activities. This section should also identify prime farmland soils on or in the vicinity of the plant site. 3.5 Hydrology Surface Water The ER should describe the surface water
