Monitoring plan for the 101 Shell Mine Monitoring wc11 Location Phase 1 -Three wells are to be drilled as shown on the plans ( Wl , w2 , & W3) to a total depth of 20' , the maxi.mum depth of the mine. : Well 1 will be located at the edge of the recharge swale on the dewatered side. and ~ill indicate if the recharge swale is operatin1 to its intended full depth. Well 2 will be located mid-distance between the r~charge swale and the wetland and will determine.if there is a positive gradient to the wetland. Well 3 will be located 200' south of the dewatering area and will give an initial estimate of the drawdown capacity of the • mining area. If the drawdown this well exceeds background data by a magnitude deemed unacceptable to the District, the recharge ditch will. be constructed on the south boundary of Phase 1. Phase 2 -One well at the edge of the recharge swale on the dewatered side (W4). Phase 3 -One well at the edge of the recharae swale on the dewatered side (WS). Phase 4 -One well at the edge of the recharge swale on the dewatered side (W6). Well construction The proposed wells consist of open ended 1 1/4" PVC casings, or larger. The well shall be installed to a depth of 20' below grade and have a 2' segment of .001" slotted pipe from 18' to 20' below grade. The top of the casing shall be marked with.its elevation per the NGVD-29 and extend 2' above grade. staff gauges Wetlands -Three staff gauges are to be placed in the two wetlands located west and one wetlandlocatednorth of the mining area. The wetland to the north is pro~sed to be monitored by water levels in the adjacent ~ater body (old mine). This location is easier to r~ad and will approximate and/or match the wetland water surface. All gauges are to be set to record NGVD elevation directly. Recharge swale -Two staff gauges, marked according to NGVD, are to be used to monitor the water levels in the two recharge swales. Pit -One staff gauge, . marked ac:cdrding to NGVD, is to be stationed in the acti\'e dewatered mine pit. EXHIBIT 14a

r Implementation of Monitoring Well Numbers 1, 2 & 3 shall be drilled as early as possible and -ater table elevations recordep at least every two weeks for background information. Wetland staff gauges shall be installed with wells 1, 2 & 3 and read at lease ever~ two weeks. Recharge swales, pit staff aauge and other wells will be placed during the applicable phase of construction. After operation of the mine coanences water levels in.the dewatering area, recharge swale and in well# 3 will be recorded daily. Wetland staff gauges. and other wells will be recorded weekly and daily if rainfall occurs. othPr recorded information; A rain gauge shall be kept on the site and recorded daily. All pumpage times with the noted R.P.M.s shall be recorded daily. Monitoring oersoooei The initial monitoring will be performed by the owner or his designee. The monitoring during excavation will be performed by the contractor. Recorded information distribution All pertinent data will be forwarded to the engineer for review at the end of each month. He shall review the information and make any necessary recommendations to the owner on a monthly basis and send a copy to the District, along with the attached recorded monitoring data. ,..... \ EXHIBIT 14b
