ved roads, parking lots, railroad spurs, exterior utility and lighting systems, potable water systems, sanitary sewerage treatment facilities, and transmission lines; • procurement or fabrication of components or portions of the proposed facility occurring at other than the final, in-place location at the facility; and • manufacture of a nuclear power reactor under a manufacturing license under Subpart F of Part 52 to be installed at the proposed site and to be part of the proposed facility. The activities defined by 10 CFR 50.10, “License Required; Limited Work Authorization,” as not being included in the definition of construction are considered to be “preconstruction” activities because they may occur in the absence of an NRC license and are not part of the NRC’s licensing action. Where this guide refers to “building,” it includes all preconstruction and construction activities. Under the revised LWA rule, the applicant should separate the impacts of preconstruction and construction activities to address the latter, as they are the activities being authorized. The applicant should also describe the impacts of the preconstruction activities, so they can be evaluated as part of the cumulative impacts related to the construction activities. Generally, the estimates of the impact breakdown between preconstruction and construction activities do not need to be detailed. For example, estimated breakdowns such as 70–30 percent or 60–40 percent or 50–50 percent should be sufficient to inform the decision-making process under the NEPA. The socioeconomic impacts of the construction activities can be apportioned simply based on these estimates. In a few areas, the level of impact may be so small that anything other than a ballpark estimate of the separation would not be warranted to appropriately inform the NEPA decision-making process. Based on experience from other construction projects of similar size, the air quality impact will probably be
