Lakewood Brick & Tile Co. <br />Church Pit - MLRB Permit # M- 1979 -045 <br />March 26, 2014 <br />The water that has accumulated in the old clay mine area <br />comes from 2 sources. One is stormwater from surface runoff and <br />the other is from water Bestway purchases from Church Ranch. <br />This water is delivered from Smart Reservoir, to the south, via a <br />pipeline and stored in the old clay mine area. The old clay mine <br />is effectively a sealed area, so the water placed in it does not <br />filter into the surrounding ground and in effect the area becomes <br />a water storage pond. This purchased water is used to supply <br />makeup water to the gravel wash plant operated by Bestway. <br />This pond does not intersect the ground water table in this <br />area. The rockwall that is the west wall of the pond is the Fox - <br />Hills formation, a solid sandstone feature that contains no <br />water. Church Ranch drilled a exploratory water well west of <br />this formation and did not reach water after drilling 1700 feet <br />and abandoned the test. At one time the Department of Energy had <br />30+ monitoring wells located east of the clay seam. Most of <br />these wells were 30 to 50 feet deep with some as deep as 100 <br />feet. When the Rocky Flats Pit (M- 1987 -113) was permitted it was <br />determined, based on the monitoring well drill logs supplied by <br />DOE, the groundwater table was in excess of 60 feet deep. The <br />bottom of the pond is less then 60 feet below the surface one <br />side is solid rock, the other 4 sides are solid clay and it does <br />not intersect the groundwater table. Water can not get in to the <br />pond expect from the surface and can not get out unless it is <br />pumped or evaporates. <br />The operators' observations over the past 50 years indicate <br />that at no time has the level of the water ever reach the top of <br />the clay seam on the south site. This would indicate it is a <br />developed confined body of water having no inflow of ground <br />water. Since it does not intersect groundwater Lakewood Brick <br />and Tile CO. is in compliance with 34.32.5- 116(4)(h) and we are <br />not required to have a permit from the Office of the State <br />Engineer. <br />
