Minerals Company, LLC <br /> SM��`�g& <br /> Coal Ridge No. 1 Mine <br /> 2016 Annual Hydrologic Report <br /> Permit C-1984-065 <br /> Dear Mr. Bowles: <br /> Please accept this letter as the 2016 Annual Hydrologic Report for the Coal Ridge No. 1 <br /> Mine. This report is for the 2016 calendar year. <br /> The Coal Ridge No. 1 Mine was reclaimed in two phases,with the majority occurring during <br /> 1994, and the remainder in 2015. Until the mine was reclaimed, eight wells were <br /> monitored (LO-1, OW-31L, OW-7, OW-8, OW-12, OW-13, OW-14 & OW-15). The <br /> groundwater monitoring wells were reclaimed late in 1994 and early in 1995. No <br /> groundwater monitoring was performed or required during 2015 (reference table 4.6-1 <br /> page 4-85). <br /> The sediment pond was reclaimed during 2015. <br /> A new discharge permit (C00048972), was issued in 2015 and is for the straw wattles <br /> associated with the 2015 reclamation. Terms of the permit include; <br /> 4, Two comprehensive stormwater inspections per year (spring and fall) <br /> ,46 At least one of the two inspections must be during a runoff event or within 24 hours <br /> of a measurable storm event or during snowmelt when a measurable discharge <br /> occurs from the facility. <br /> ,.k For the remaining two quarters (summer and winter) conduct corrective actions <br /> across the facility for deficiencies represented by each DRMS inspection finding in <br /> one of the monthly (or as appropriate, quarterly) SMCRA inspections. <br />
