increases are allowed over naturally occurring turbidity. "Naturally occurring," as defined by ARM 

 17.30.602 (17), includes conditions or materials present during runoff from developed land where all 

 reasonable land, soil, and water-conservation practices (commonly called BMPs) have been 

 applied. Reasonable practices include methods, measures, or practices that protect present and 

 reasonably anticipated beneficial uses. These practices include, but are not limited to, structural 

 and nonstructural controls and operation and maintenance procedures. Appropriate practices may 

 be applied before, during, or after the completion of activities that may impact the resource. 



The designated beneficial surface-water use within the project area is cold-water fishery. Beneficial 

 uses on Cilly Creek include domestic water use approximately 1 mile downstream from the 

 proposed project area. 



Water-Quality-Limited Waterbodies: The proposed project area is located within the Cilly Creek 

 watershed. Cilly Creek is not listed in the 1996 or 2004 List of Waterbodies in Need of Total Maximum 

 Daily Load (TMDL) Development publication produced by the Montana Department of Environmental 

 Quality (DEQ, 1996, 2004). Cilly Creek is tributary to Swan River and Swan Lake, however, and Swan 

 Lake is listed as impaired on the 2002 List of Waterbodies in Need of TMDL Development . 



Montana Streamside Management Zone (SMI) Law: By the definition in ARM 36. 1 1.312(3), Cilly Creek 

 is a class 1 stream. Cilly Creek flows less than 6 months per year in the reach located within the 

 proposed project area, but does contribute surface flow to another stream and supports fish when 

 flowing, and, therefore, meets the class 2 definition. 



Forest Management Rules: By definition in ARM 36. 1 1.403 (95), each parcel of the proposed project 

 area may contain isolated wetlands. As required in ARM 36. 1 1.426, wetlands greater than one-quarter 

 acre in size should have a 50-foot Wetland Management Zone (WMZ) delineated around their perimeter. 

 For wetlands smaller than one-quarter acre in size, the WMZ would be delineated on the wetland border. 



WATER QUALITY 



The bed and banks of Cilly Creek are in stable condition through this portion of the project area, and 

 streamside vegetation is intact with good riparian function. No bank cutting or channel degradation 

 were noted in reaches extending through the proposed salvage area. The road system used to 

 access the proposed project area is on moderate to gentle grades and has some surface drainage 

 installed. Some additional surface drainage and erosion control may be needed on this road 

 system, but no erosion or sediment delivery was identified during field reconnaissance. 



DIRECT AND INDIRECT EFFECTS 



Direct and indirect effects of the No-Action Alternative would be similar to the conditions 

 described under EXISTING CONDITIONS for WATER QUALITY. The water quality would be 

 unaffected by the No-Action Alternative, and Cilly Creek would continue to be affected by 

 natural and preexisting conditions. 



No stream crossings would be replaced and no road-surface drainage would be improved or 

 added.

The proposed project would salvage timber from approximately 89 acres. No water-yield 

 increases are anticipated as a result of the proposed activities since the only trees proposed for 

 removal have either been killed by insects or diseases or have been damaged by insects or 

 diseases to the point that death is imminent. No increases in sediment delivery are expected 

 since none of the proposed units contain a stream. 



The Action Alternative would also improve the erosion control and surface drainage where 

 needed on all existing roads proposed for hauling in the proposed project area; these roads
