' CNAPTERFOUR Environmental Consequences <br />' increment consumption. The project would be responsible for filing all applicable construction <br />permit applications, Title V Operating Permit Applications, Air Pollution Emission Notices, <br />Fugitive Dust Control Plans, and compliance plans in the manner and within the timeframe <br />required by the CDPHE. The air quality construction permit applications prepazed by RTP <br />Environmental Associates, Inc., addressing New Source Review (NSR) and PSD provisions, <br />submitted to CDPHE, is a primary reference for this section (RTP 1998a,b). The land manager <br />' of the PSD Class I or state Category 1 areas is responsible for providing input to the permitting <br />process regazding potential impacts to air quality and AQRVs. <br />AQRVs of concern include potential impacts to visibility and the potential acidification of <br />sensitive lakes. Visibility impacts include regional haze and visible plumes at the neazest <br />Wilderness Area (Flat Tops Wilderness Area), and associated integral vistas. Visibility impacts <br />' aze generally associated with increased concentration in the atmosphere, of small, light-scattering <br />particles (such as sulfates and nitrates), or increases in light-absorbing gases [usually nitrogen <br />dioxide (NOZ)]. <br />4.5.2 Direct and Indirect Impacts <br />All of the impacts from this project aze expected to be a direct result of the construction or <br />operation of the Proposed Action. There is a significant demand for electricity, but this would be <br />supplied by the local rural electric utility, through a transmission line, and is not expected to <br />result in the construction of additional electrical generation capacity. The work force is expected <br />to generally be accommodated with the available resources, and would not result in the creation <br />of significant new sources of emissions. <br />4.5.2.1 Proposed Action <br />' Effects of Construction <br />The following discussion introduces the project sources that aze included in the air quality <br />analysis. The impacts resulting from these sources aze presented in the Modeling <br />Results/Analysis Section. <br />' Piceance Site <br />General construction activities would create emissions of fugitive dust and particulate matter less <br />' than 10 microns (PMio). Additionally, gaseous pollutant emissions such as NOx, CO, S02, and <br />volatile organic cazbons (VOCs) would result from operation of drilling equipment. <br />The description of the Proposed Action and alternatives (Chapter 2) includes estimates of the <br />' amount of equipment expected during construction of the Piceance Site. An analysis of the <br />fugitive dust that would be generated by the construction activities and related vehiculaz traffic is <br />provided in the construction permit application prepazed by RTP Environmental Associates, Inc. <br />(RTP 1998a). This analysis uses the very conservative factors found in the compilation of air <br />pollutant emission factors (EPA 1996). Although the fugitive dust would cause some visible <br />' dust clouds, impacts would be temporary and localized. <br />' Meteorology and Air Quality 4-19 <br />
