Environmental Consequences/Mitigation: Proposed Action - Environmental consequences described in the 2005 Spruce Stomp Federal CEL EA still accurately describe potential impacts associated with this proposal. With the dust control measures included in the proposed action, no measurable changes in air quality can be expected from this proposed action. Cumulative Impacts - Combined with all the other activities in the local area, the proposed action is not expected to result in any detectable change in cumulative air quality conditions, or result in any global warming effects. No Action Alternative - There would be no project related effects to local air quality conditions. WILD AND SCENIC RIVERS Affected Environment: The BLM has released a final Wild and Scenic River Eligibility report (BLM 2010a). The BLM has determined that the West Fork of Terror Creek has Outstandingly Remarkable Values, and is potentially eligible for inclusion into the National Wild and Scenic River System. The "outstandingly remarkable value" for this segment of stream is the native fishery, specifically the Threatened greenback cutthroat trout. A suitability determination has not yet been made, but will be made in the context of the Resource Management Plan the Uncompahgre Field Office has commenced. With the exception of the • existing Terror Creek road near the confluence with Terror Creek, the BLM portions of West Terror Creek remain undeveloped. USFS portions of West Terror Creek are not designated as Wild or Scenic. Environmental Consequences/Mitigation: Proposed Action - Exploration drill pad BRL 2010-1 location is within the 0.25 mile buffer on either side of the BLM Eligible segment of the West Fork of Terror Creek. Likewise, the previously authorized right-of-way to PRP SS 9 would be constructed within the 0.25 mile buffer of the BLM Eligible segment. Neither the exploration drill pad nor the access road on the existing right-of-way would be visible from the bottom of the West Fork of Terror Creek. With the application the committed mitigation in Bowie's proposed action and the requirements set forth in the endangered species, water quality, and aquatic resources sections of this document, there should be no detectable effect on the "outstandingly remarkable values" for which this stream segment was found to be eligible. Mitigation: See endangered species, water quality, and aquatic resources sections for mitigation that would protect the "outstandingly remarkable values" of the West Fork of Terror Creek. Cumulative Impacts - None No Action Alternative - There would be no impacts from coal exploration activities. DOI-BLM-CO-S050-2010- 0017 EA Page 17 of 43 May 2010
