us of the site of nonattainment and maintenance areas defined under the Clean Air Act, as amended, and a list of mandatory Class I Federal areas within the same radius. 3.3 Noise The ER should provide information about current or past noise studies and analyses conducted at or near the nuclear plant site. In particular, the ER should identify the loudest noise-generating facilities and activities and indicate their distance to the nearest site boundary. 3.4 Geology and Soils Geology The ER should describe, in general, the site geologic setting, including brief definitions of the rock types present, formation names, thicknesses, and general engineering properties. The ER should briefly discuss seismicity, including the seismic history of the site, and identify the safe-shutdown earthquake, along with the largest historic regional earthquake. Soils The ER should describe, in general, the soils at the plant site, including unconsolidated material which may be naturally occurring or consist of fill. Using engineering terminology, soils are also referred to as overburden (i.e., the unconsolidated material overlying bedrock). The ER should describe the soils, along with their relationship to the site geology (e.g., identify whether fill material was brought in from 3 Criteria pollutant or standard means any pollutant for which there is established a NAAQS at 40 CFR Part 50, “National Primary and Secondary Ambient Air Quality Standards.” In addition, 40 CFR 51.852, “Definitions,” describes the precursors of a criteria pollutant. 4 An area is designated “nonattainment” for a criteria pollutant if it does not meet the NAAQS for the pollutant. A maintenance area has been redesignated by a State from nonattainment to attainment; the State must submit to EPA a plan for 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
