(BMRI) - San Luis <br />DMG Permit No. M-88-112 <br />Request for Technical Revision No. 20 <br />Process Water Tank Storage Area <br />Dear Mr. Dillie: <br />ne MourvwN <br />D COMPANY <br />~ /C,' ~~ <br />This letter serves as a request for a technical revision, TR-020, <br />to construct a storage area around the process water hank. The <br />storage area will be approximately 151 'x 52', a total of 7,900 ft2. <br />This additional area will enable BMRI to store equipment and <br />supplies more effectively. A 10' wide ramp will be proviQ~ed on the <br />north end of the storage area for easy access to equipment and <br />supplies. <br />The storage area will have a one foot depth. Section A-A of the <br />enclosed map shows that the concrete will be 6" in thickrness. The <br />area will be cold jointed with a waterproof seal to the existing <br />concrete slab floor of the process 'tank pump house. Expansion <br />joints will be located down the middle of the length and the width. <br />The reclamation cost for the process water tank storage area is <br />based on estimated costs from the approved reclamation plan. <br />Concrete removal costs for a 4" floor are $1.69/ft2 andl for a 5" <br />floor are $2.59/ftZ, it is estimated that removal costs for a 6" <br />floor will be $3.49/ft'-. The storage area is 7,900 ftZ and 6" thick <br />so the estimated concrete removal is $28,000. <br />This addition is located within an already disturbed area; <br />therefore, ripping, grading, topsoil replacement, and seeding costs <br />have been accounted for in the approved reclamation plan. The <br />total additional cost of reclamation for the new storage area, <br />including a contingency of 25°s, is $35,000. This represents only <br />1°s of the existing $3.3 million reclamation bond. <br />A SU05/DIARY' OFOA7TLF MOUA7A/N GOL/I COMPANY <br />P.O. BOX 71U SAN LUIS, COLORADO 8115?0310 (719)67?-}36?
