Exhibit "D" <br /> (Supplement) <br /> (1) The applicant BIG "G" GRAVEL PIT will prepare a Storm Water Management Plan <br /> (SWMP) and a Spill Prevention Control and Counter measure (SPCC) plan, for this site. <br /> As you know each SPCC plan, while unique to the facility is covers, must include certain <br /> elements. The elements required are that the SPCC plan be carefully thought out, <br /> prepared in accordance with good engineering practices, and should address operating <br /> procedures that prevent oil spills; control measures installed to prevent a spill from <br /> reaching navigatable waters; and counter measures to contain clean up, and mitigate the <br /> effects of an oil spill that reaches navigable waters. To meet the above requirements a <br /> Storm Water Management Plan and a Fuel Berm Management Plan, plus a Spill <br /> Prevention Control and Counter Measure Plan will be done for this site. A permit from the <br /> Colorado dept. of Health & Environment Water Quality Control Division will also be <br /> obtained. Copies of all the above plans and permits will also be sent to the Division of <br /> Reclamation, Mining and Safety. <br /> (2) BIG "G" GRAVEL PIT will commit to placing overburden stockpiles along the low edge <br /> of all the mining phases as a first step of mining operations, the berms and pits created will <br /> control erosion and sedimentation. The operator is committed to control (prevent)erosion <br /> and sedimentation from reaching any drainage. All methods of control will be used, <br /> sediment traps, riprap, straw bales, earthen berms and liners. <br /> (3) Bulk storage of fuel, and small amounts of lubricates, will be stored on site in an <br /> earthen berm with an approved liner around and below the storage container. The earthen <br /> structure will have a capacity of at least 110% of the tanks and containers tanks. This type <br /> of structure will be leak resistant and readily cleanable if a spill does happen. The liner will <br /> form a pool that the liquid cannot escape to the surrounding areas. The other features of <br /> this structure is that it will be designed in such a way that it will be easy to clean up any <br /> 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 nearest <br /> approved disposal site. <br /> (4) BIG "G" GRAVEL PIT does agree and will commit to Division of Reclamation, Mining <br /> and Safety'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 hazardous substance (including spills of <br /> petroleum products)within the permit area will be reported to any and/or the Division of the <br /> Colorado Department of Public Health and Environment, the National Response Center, <br /> the Colorado Emergency Planning Commission, a local Emergency Planning Commission, <br /> or the State Oil Inspector. In addition the operator shall notify the Division of Reclamation, <br />
