The grading of final slopes, the placement of soil, and associated erosion control measures shall take place prior to November 1 in areas where mining has been completed. To minimize erosion, the finish grading of disturbed slopes shall be performed as soon as practical after mining has been completed. A drought-tolerant, weed-free mix of native and non-native grass species shall be established on slopes prior to November 1 or alternate erosion control (mulch or netting) shall be placed on exposed soil on the slopes prior to this date. Phasing of mining to minimize the length of exposed mining slopes during the rainy season is encouraged. An extension to the November 1 deadline may be granted in writing at the discretion of the Director, weather conditions permitting. (§ 2, Ord. 1276, eff. December 6, 2001)
