2013 AHR Page 4 <br />to 2012 as depicted on enclosed diagram S13 -5. <br />Rapid Creek monitoring site SWGS 01, along with both of the flow comparisons (Colorado River <br />and Plateau Creek) and the Rainfall and Snowpack data show downward trends in flow, rainfall <br />and snow accumulation from 1986 to 2012. Based on this data, one can conclude the slight <br />downward trend of flow in Rapid Creek was most likely caused by climatic conditions. <br />Monitoring on Coal Creek and Jerry Creek started in 1995. The crest stage gages installed in <br />Coal Canyon drainage and Jerry Creek in 1996 were destroyed by a storm in the summer of <br />1998. Discussions with DRMS indicated there was no need to monitor the upstream locations <br />SWGS 07 and 09. The creeks will only be monitored at the lower monitoring points. The <br />ephemeral flow in Coal Creek is measured at culverts located between the two refuse disposal <br />areas, SWGS 06. These culverts provide a stable cross section and are accessible throughout <br />the year. The intermittent flow in Jerry Creek was measured at the culvert near the Highline <br />Canal, SWGS 08. Beginning July 1999, instantaneous flows are to be monitored monthly. Data <br />taken during the Year are listed on data pages SR -3 and SR -4 for Coal Canyon. Monitoring <br />was suspended for Jerry Creek (SWGS 08) with the approval of TR62 on 11/8/11, therefore, no <br />monitoring was performed for SWGS 08 during the Year. <br />There were four seeps included in the hydrologic monitoring in 1995. The locations of the <br />seeps are shown on the Hydrologic Monitoring Map. They are located adjacent to Coal Canyon <br />drainage and Jerry Creek. They are primarily evident by the white staining on the hillsides from <br />evaporation of the seeps. None of them flow to the creek channel but generally evaporate <br />within a couple of hundred feet of the source. On April 19, 2006, Snowcap Coal Company <br />submitted a technical revision, TR50, requesting to discontinue seep monitoring. The request <br />was approved by the Division on July 25, 2006. Therefore, no monitoring was performed during <br />the Year. <br />There was no discharge from CDPS discharge points 005 thru 015 during the Year. These <br />outfalls cover sediment pond discharges. Discharge point 015, now inactive, was permitted to <br />allow pumping water from the south end of the Roadside South Portal out the 2 West portals. <br />Discharge point 016 is permitted for gravity discharge from the northwest intake pool. It <br />replaced outfalls 001 and 002 on March 31, 2002. <br />Discharge point 001 was primarily used as an overflow to a mine water system for the <br />preparation plant during mine operations. During March and April 2000, a discharge pipe was <br />installed from the No. 2 South Mains sump to outfall 001. The routing of this 4 -inch diameter <br />pipe is presented on permit Figure 14 -6. The capacity of this discharge pipe was about 75 gpm. <br />Flow ceased at discharge point 001 on March 31, 2002. Discharge point 001 was reclaimed <br />during the 15' quarter of 2008 and is no longer operational. <br />Discharge point 002 was water siphoned from the reclaimed Northwest Intake Portal at the <br />Roadside South Portals. Mine inflows that were not pumped to the preparation plant were <br />
