EXHTBIT D-MTNTNG PLAN <br />The applicant LEONE SAND and GRAVEL, LLC will prepaze a Storm Water <br />Management Plan (SWMP) and a Spill Prevention Control and Counter measure (SPCC) <br />plan, for this site. As you know each SPCC plan, while unique to the facility it covers, <br />must include certain elements. The elements required are that the SPCC plan be cazefully <br />thought out, prepazed in accordance with good engineering practices, and should address <br />operating procedures that prevent oil spills; control measures installed to prevent a spill <br />from reaching navigatable waters; and counter measures to contain, clean up, and <br />mitigate the effects of an oil spill that reaches navigable waters. To meet the above <br />requirements a Storm Water Management Plan and a Fuel Berm Management Plan, plus <br />a Spill Prevention Control and Counter Measure Plan will be done for this site. A permit <br />from the Colorado dept. of Health & Environment Water Quality Control Division will <br />also be obtained. Copies of all of the above plans and permits will also be sent to the <br />Division of Minerals & Geology. <br />LEONE SAND and GRAVEL, LLC will commit to placing topsoil and overburden <br />stockpiles along the entire low edge of all the mining phases as a first step of the mining <br />operations, the berms and pits created will control erosion and sedimentation. The <br />operator is committed to control (prevent) erosion and sedimentation from reaching any <br />drainage. All methods of control will be used, sediment traps, riprap, straw bales, earthen <br />berms and liners. <br />Bulk storage of fuel, and small amounts of lubricants, will be stored on site in an earthen <br />berm with an approved liner around and below the storage containers. The earthen <br />structure will have a capacity of at least 110% of the tanks and containers tanks. This <br />type of structure will be leak proof and readily cleanable if a spill does happen. The liner <br />will form a pool that the liquid cannot escape to the surrounding areas. The other features <br />of this structure is that it will be designed in such a way that it will be easy to clean up <br />any possible spills. All spills will be soaked up with an absorbent material such as sand or <br />other substances that can absorb the spilled oils or lubricants. After the mixture of <br />absorbents and oil are cleaned up all the waste materials will be transported to the neazest <br />approved disposal site. <br />LEONE SAN and GRAVEL, LLC does agree and will commit to Division of Minerals <br />and Geology's permit condition as stated on page (6) six in the application package. Any <br />reportable spill which is a spill of any toxic or hazazdous substance (including spills of <br />petroleum products) within the permit area will be reported to any and/or the Division of <br />the Colorado Depaztment of Public Health and Environment, the Nafional Response <br />Center, the Colorado Emergency Planning Commission, a local Emergency Planning <br />Commission, or the State Oil Inspector. In addition the operator shall notify the Division <br />of Minerals and Geology of a reportable spill within the permit azea using the same <br />timeframe required by the permit, license, notice, Act, Rule or Regulation governing the <br />reporting of the spill to the appropriate agency. Notice of a reportable spill shall be Faxed <br />to: Minerals Program Supervisor, Division of Minerals and Geology, FAX (303) 832- <br />8106. this FAX will include a callback number of a responsible official for the DMG staff <br />to use as a contact. <br />
