Bill Schinderlein with Blue Earth Solutions will be submitting to the Division under separate <br /> cover the conceptual drawings as soon as those are completed. <br /> The Army Corps of Engineers will require a permit. Fremont Paving and Redi Mix is working with <br /> Blue Earth Solutions to complete that permit application. That will be sent under separate cover <br /> when it has been submitted. <br /> 2. A. Please see the enclosed APEN and SPCC plan for the Gencor portable plant. <br /> B. Fremont Paving and Redi Mix is currently working with LPEA to design the move of the <br /> existing power line. To date, we are unsure when that move will occur. If those lines are in <br /> their current location when mining commences, Fremont Paving and Redi Mix will maintain <br /> a 50' setback from each of the two poles that are in the mining area. Those setbacks will be <br /> delineated with stakes for a clear visual barrier. A structure agreement for the electric line <br /> was included in the original submission. <br /> C. After researching the potential recharge rate of the area,we believe that 2,100 gallons per <br /> minute is the highest rate of recharge. The type of pump that could be used on site is the <br /> Godwin CD150. It has an approximate pump rate of 2,179 gallons per minute and will give <br /> enough pumping ability to dewater the site. A specification sheet has been attached for <br /> reference. <br /> 3. A. The pond slopes will be mined at a 3H:1V slope. There will be approximately 2,880 linear <br /> feet of new shoreline. <br /> B. There will be 2 acres that will be mined and revegetated. There will be 4.3 additional acres <br /> disturbed that may potentially need revegetated as well. For the two acres that will be <br /> ASPHALT CONCRETE • SAND & GRAVEL <br /> Equal Opportunity Employer <br />
