Sherman Executive Director Ronald W. Cattany Division Director Natural Resource Trustee Re: CBCI Gravel Pit, File M-2009-030, 110c Application: Adequate for Approval, and Estimate of Bond Amount. i Dear Mr. Cressler, The Division has reviewed the adequacy responses you provided on September 23, 2009, and finds that the application is ade uate for approval. The Limited Impact 110c permit application for your gravel pit was approved on September 28, 2009. A few details of the approved operation are listed below, some of which incorporate your written responses. 1. The operator must post a permit ID sign at the entrance to the site, per Rule 3.1.12. All permit boundaries must be marked in a durable and visible manner throughout the life of the permit. 4. 2. Most of the material to be mined is the broken sandstone layer, though a small percentage of the material mined may be the underlying shale. The result of mining either material will result in a pit no deeper than 15 feet. Most mining will be conducted by bulldozer and/or loader, but there may be some material removal utilizing explosives. The operator will ensure that all necessary licenses are obtained. Portions of the pit floor may receive a shallow layer of clean, inert construction debris before the pit is reclaimed. Up to 500 cubic yards of debris may be accumulated in a stockpile onsite before it is backfilled and spread. The layer of debris may average about 2 feet thick, and a layer of overburden may be required as a cap prior to placement of topsoil. Topsoil will be gradually stripped from areas prior to being mined. Topsoil will be stockpiled onsite in areas away from mining and processing disturbance. If it is not to be replaced within a year of being stripped, the topsoil stockpiles will be seeded to protect them from erosion. The site will be monitored for weeds, in areas disturbed by mining and areas not yet disturbed. All noxious weed infestations will be promptly treated. If treatment is not effective, a more aggressive plan must be developed. 6. No fuel or lubricants may be stored onsite unless all storage vessels have impermeable secondary containment. I have ?,nclosed a packet which contains the estimated reclamation costs. Please review the packet and notify me prompt Ily if you notice any errors or omissions. The first page is the summary of all tasks, and the following pages show the detailed breakdowns of each task and the equipment production figures. Please be reminded that the figures represent the cost to the state to hire a reclamation contractor; minimizing your disturbance and maintaining a clean site wil'1 help keep the bond low.
