A discussion of projected impacts can be found in Section III F. -Assessment of Probable Hydrologic Consequences of Mining. SCC performs a spoil spring survey following snowmelt each year, with locations of springs of greater than 5 GPM added to the monitoring program, with spring location and monitoring data to be included in subsequent Annual Hydrology Reports. An anneal total of approximately 2 full-suite samples and 4 field parameters samples are collected each year, timed in order to characterize water quality and flow during the high-water and low-water seasons. Surface Water The applicant will conduct monitoring of surface water in a manner approved by the Division. The monitoring plan was submitted under 2.05.6(3)(b)(iv) and can be found in Appendix 15-3A of the permit application package. The hydrologic description of the mine area is provided in Tab 7 of the permit, and the hydrologic monitoring plan is addressed in Tab 15. Hydrologic protection, probable hydrologic consequences, and the hydrologic reclamation plan are presented in Tabs 16, 17, and 18, respectively. Surface water at the Seneca II-W Mine lies within two watersheds. The primary affected area lies within the Dry Creek Drainage and is drained by Hubberson Gulch and an unnamed tributary to Dry Creek (the Pond 005 Gulch). A small portion of the eastern part of the permit area drains to Sage Creek. Both creeks empty into the Yampa River near Hayden. Both Dry Creek and Sage Creek exhibit intermittent to perennial flows, depending on location along the streams, and precipitation trends. Hubberson Gulch is intermittent. Hubberson Gulch Watershed Seneca Coal Company currently (October 2004) monitors one upstream site (SG9) and two sites downstream of mining disturbance on Hubberson Gulch (SG7 and FGl). These are in addition to NPDES monitoring sites located at Pond 017 outfall on upper Hubberson Gulch, and Pond 016 and 006 outfalls on Hubberson Gulch tributaries. SG9 is located upstream from Pond 017, and above any mine related discharges in the south extension area. Monitoring was conducted from 1997 through 1998, and reinitiated in 2000, with monitoring conducted June and September. SG7 (upstream of 006 Gulch confluence and downstream of 016 Gulch confluence) is monitored monthly for flow and field parameters, and triannually Seneca II-W Findings Document 36 November 17, 2004 Permit Revision No. 4
