State Re4. <br />• solutions to the problem, i.e., riprap, straw dikes, etc. <br />Upon reclamation, these erosional problem areas will be <br />rectified. Peabody Coal Catgaany will monitor during the year, <br />with mine site personnel, these breached areas in onier to <br />assure the topsoiled slopes are in compliance with Rule <br />4.14.6. <br />Drainage frrun haul roads within the estimated disturbance <br />areas (see Exhibit 12-1) will be constructed to meet the <br />rr~rniiramantS of 4.05.2 and such haul roads will at a mininn im <br />be constructed and maintained to minimize erosion of the <br />disturbed area. Erosion control measures used singly or in <br />combination include but are not limited to: <br />a. Stabilizing all exposed surface areas to prmrote a <br />reduction in the rate and volume of runoff; <br />• b. Using straw dikes, riF¢ap, check dams, berms, geotextile <br />materials, mulches, vegetation c~x7imant filters, contour <br />furrows, or other TM~~'~res that reduce overland flaw <br />velocity, reduce runoff volume, or trap ~7i~nt; or <br />C.
