• (Page 21 • <br />MINE ID # OR PROSPECTING ID # M-80.743 <br />INSPECTION DATE 9-16-96 INSPECTOR'S INITIALS SSS <br />OBSERVATIONS <br />This inspection was conducted at the request of a neighbor to the operation who indicated that recent heavy, long duration <br />rainstorms, had caused a lot of siltation in their fish ponds. The neighbor indicated the sediment originated on the Texas Creek <br />Gravel Pit site. Bruce IVeil was contacted and agreed to meet the inspector at the pit. This inspection was conducted 9:30 AM, <br />the day the complaint was received by phone, in order to assess the situation as soon as possible after the subject storm event <br />which ended approximately two days prior. <br />Some minor rills were n4oted on the pit slopes, but these were few and not large erosional features. There was evidence that runoff <br />had been leaving the site, but no heavy deposits of sediment were noted. Flow from the site crosses under county road 501 by <br />way of a culvert approximately 12" in diameter. The flow then proceeds overland through vegetated areas and areas that are bare <br />dirt in an adjacent neighbors yard. The flow then proceeds through a heavily grassed area and across a wide fresh gravel pad that <br />was laid down by Neil's Excavation, the operator of this pit. From the pad, the flow enters the fish ponds of the complainant. <br />The fish pond water was cloudy with sediment. However, tracing the flow pattern of the runoff from the pit, there were no <br />noticeable sediment deposits in areas where the water would have pooled and dropped out suspended solids. The vegetation in <br />the path of the flow was not covered with sediment either. It appears that there are several sources of sediment that the flow could <br />have picked up, including the gravel pit, the bare dirt patches in the neighbor's yard and the complainants own gravel pad area. <br />Though it was not clez~r that the problem was, for the most part, caused by the gravel operation, the operator agreed to construct <br />some sediment control structures consisting of berms and sill fences (straw bales). The operator was reminded that an application <br />for a stormwater permit will need to be submitted to the Colorado Department of Public Health and Environment for control of runoff <br />from the site. The structures proposed by the operator may suffice for the controls required to obtain an approved stormwater <br />permit. <br />In 7987, the U. S. congress amended the Clean Water Act to expressly include storm water discharges from industrial sites as <br />requiring Clean Water Act controls. In 1 990, EPA issued regulations that require specific industrial activities to obtain permits in <br />order to discharge storm water from their Tacilities. Active and inactive mining operations where storm water comes into contact <br />with overburden, raw material, intermediate products, byproducts, finished products or waste products located at the mining site <br />are specifically included. The deadline to apply for a storm water permit was October 1 , 1 992. If a storm water permit for this mine <br />has not yet been obtained, the operator must apply for such a permit, as soon as possible, to Colorado Department of Public Health <br />and Environment, WOCD-PE-B2, 4300 Cherry Creek Drive South, Denver, Colorado 80222-1530. If any significant storm water <br />control structures are required to be constructed at the mine as a result of the storm water permitting process, a revision must then <br />be submitted to this Drvision fo incorporate the operational and reclamation aspects of such structures in the Reclamation Permit. <br />I & E Contact Address <br />NAME <br />OPERATOR <br />STREET <br />CITY/STATE/ZIP <br />Bruce Neil <br />Neil's Excavating <br />486 County Road Sts <br />Ignacio, Colorado 81137 <br />cc: Tom Gillis, DMG <br />^ CE <br />^ BL <br />^ FS <br />^ HW <br />^ HMWMD (CHI <br />^ SE <br />^ WOCD ICH) <br />^ OTHER <br />
