The pit was operated by Schmidt Construction Company. An aerial of the pit <br /> is attached with this letter. <br /> It is our understanding that the existing perimeter soil berms are to be removed as part of the mine <br /> closure. Information regarding the berms composition and construction was provided by Scott Davis <br /> who was the project manager on the Black Forest Property (Vollmer Pit) for Schmidt Construction. <br /> The berms were placed to shield the pit operations from view of surrounding properties. The berms <br /> were reportedly constructed from the overburden soils within the pit. The overburden soils in this <br /> area typically consist of Silty sands. Scrapers and dozers were reportedly used to place the berm <br /> materials. <br /> The berms to be removed are constructed above adjacent grades. The removal of the berms will <br /> not require excavation below the grades of the adjacent properties. Due to the use of overburden <br /> soils from the pit to build the berms, efforts to remove them are not expected to be difficult. It is <br /> anticipated that the berm soil will be picked up with scrapers to be placed within the interior of the <br /> property. One house is situated with its side yard adjacent to the property (see site aerial). The <br /> remaining adjacent structures have rear yards between houses and the property. The distance from <br /> the toe of the berm to the nearest house is approximately 40 feet. The majority of the earth moving <br /> will be at distances greater than 50 feet. Again, no excavation for the berm removals will be below <br /> the existing grade outside of the berm area. <br /> It is our opinion that the berm removal will not impact the adjacent properties based on our <br /> observation of the site, the proposed construction, location, and the grades of the berms. During <br /> operations, BMP;s for erosion and dust control should be implemented. <br /> We trust that this has provided you with the information you require. Should you have any questions <br /> or need further information, please do not hesitate to contact us. <br /> Respectfully Submitted, <br /> ENTECH ENGINEER! , 1t tio •a��0F <br /> O .• OLLI V •,ycr <br /> • G to <br /> C Goode Jr. I ,L 2372 JX <br /> esident <br /> c <br /> JCGlrb <br /> �o :• a: <br /> Enclosure �Ss�oNAL"* <br /> Entech Job No. 171070 <br /> F.'"PM*-s12018U710701171070.Berm doe <br />
