As is seen from the two tables above, acct/fill balance is more or less achieved. Slight variations <br />with the extra fill needed for lake slopes, shrink swell factors, as well as other variables may alter <br />this balance to some degree, however, it is a best estimate for planning purposes at this time. Map F <br />shows the final locations of the proposed pad areas and final lakes. <br />The highest production and average production rates for the site are as follows: <br />Commodity Annual Maximum Annual Average Production Rate <br /> Permitted Produc- <br /> tion Rate <br />Sand and Gravel 350,000 tons/yr 220,000 tons per year <br />Asphalt 150,000 tons/yr 130,000 tons/year <br />Aggregate for 108,000 tons/yr 100,000 tons/year <br />Concrete <br />Therefore, the total average tonnage per year removed from the site is 450,0000 tons per year. <br />This average can fluctuate depending upon demand, contracts, etc. <br />The approximate gravel reserves in each Mining Area and the time to mine out each area is given <br />below: <br />Mining Area Acreage Avg.
