Final Compensatory Mitigation and Monitoring Plan—Version 2.0 <br />Climax Mine Overburden Storage Facility Expansion (SPK-2013-00045) <br />March 2017 Bikis Water Consultants, a division of SGM Page 9 <br />Unvegetated shallow open water (PUBH). Several areas of shallow, permanent ponding <br />that lack vegetation exist. This includes two artificially created areas (PUBHr). <br />Intermittent streambed (R4SB3). Channels exist that flow only during or after snowmelt <br />runoff and precipitation events. These channels are comprised of gravel and cobble <br />substrate. <br />Perennial streambed (R3UB1). While most of the channels in the study area do not <br />have perennial flow, several reaches with perennial flow exist due to persistent springs. <br />These channels are comprised of gravel and cobble substrate. <br />It should be noted that the occurrence and boundaries of fens do not correspond well with plant <br />species or topographic position. The plant community in fens varies, and fens are found in <br />depressions and relatively flat areas, and also on side slopes. <br />5.1.1 Water Sources <br />Most of the wetlands lack extensive areas of standing water, but are saturated to or close to the <br />surface during the growing season, and may lack saturation towards the end of the growing <br />season. Most of the wetlands are slope wetlands under the hydrogeomorphic (HGM) <br />classification system, and their primary water source is groundwater from springs and seeps. <br />Water associated with the channels, which includes spring water, sustains the wetlands along <br />the channels. Snowmelt is a major water input for the hydrologic system. <br />5.1.2 Soils <br />The web soil survey (http://websoilsurvey.nrcs.usda.gov) was researched regarding the <br />presence of soils information for the study area. The web site indicated that no soil survey <br />information exists for the area. <br />Soils were mapped on Climax property including McNulty Gulch by Habitat Management, Inc. <br />This map is based on soil mapping by the Pike and White River National Forests on and <br />adjacent to the Climax property in 1995 using mapping techniques and nomenclature approved <br />by the National Resources Conservation Services (NRCS). This mapping shows that the lower <br />part of McNulty Gulch is predominantly Leadville soil, which is described as well-drained soil <br />with a water table of greater than six feet that has been influenced by glacial processes.
