ENVIRONMENTAL ASSESSMENT <br /> Cumulative Actions and Effects <br /> The CIAA for noise is the Project Area, including the length of CR 120 to SH 140 and an approximately 1- <br /> mile buffer around the area. Cumulative noise and vibration effects for the Proposed Action would be <br /> related to changes in mining location in addition to equipment use and number oftrucktrips,which would <br /> remain generally the same.These effects could be additive if additional use of the road system increases <br /> through reasonably foreseeable activities such as oil and gas development, additional residential <br /> development,or increased ranching and agricultural activities. However, recent implementation of design <br /> features, such as constructing noise barriers and paving segments of road, has reduced cumulative noise <br /> impacts to nearby residences. <br /> Noise and vibration effects for the Proposed Action consider equipment use and truck trips for the <br /> maximum allowable coal production under the current mine permit. If GCCE were to change mobile <br /> equipment or desire to increase coal production above permitted levels, it would be required to apply for <br /> a permit revision with CDRMS and the OSMRE. These agencies would evaluate the potential noise and <br /> vibration effects associated with the proposed permit changes. Therefore, the cumulative noise and <br /> vibration effects for the Proposed Action are the same as baseline levels because noise and vibration levels <br /> allowed under the current mine plan would be enforced. Cumulative effects would be long term and <br /> negligible to minor. <br /> Effects of Alternative B—No Action Alternative <br /> Direct and Indirect Effects <br /> Under the No Action Alternative, the LBA would not be offered for competitive lease sale by BLM, there <br /> would be no mining plan modification to be considered and approved by OSMRE and federal coal reserves <br /> in the LBA and new private reserves would not be recovered.The King II Mine would continue to operate <br /> as allowed by the current mine plan until the existing coal reserve is mined out, and noise impacts would <br /> be the same as those under the current operation. Under this alternative, the King II Mine would shut <br /> down around 2022. When coal reserves are completely depleted, there would be no coal-hauling truck <br /> traffic or associated noise and vibration along CR 120 <br /> Cumulative Actions and Effects <br /> Cumulative impacts under the No Action Alternative would be the same as under the Proposed Action but <br /> would be limited to the current lease and permit areas. <br /> 3.4.5 Resource Issue—Wetlands/Waters of the U.S. <br /> What would be the effects of the alternatives on identified wetlands and WOTUS? <br /> 3.4.5.1 Affected Environment <br /> In general, potential wetlands in the Project Area are generally associated with manmade ponds and <br /> intermittent streams that may support wetland vegetation. Common wetland and riparian plant species <br /> that would be expected to occur in the Project vicinity, especially in Alkali Gulch and Hay Gulch, include <br /> narrowleaf cottonwood (Populus angustifolia), narrowleaf willow (Salix exigua), water birch (Betula <br /> occidentalis), duckweed (Lemna spp.), rushes (Eleocharis and Juncus spp.), sedges (Carex spp.), bentgrass <br /> (Agrostis spp.), and broad leafcattail (Typha latifolia).
