D. Sedimentation Ponds <br />Two sediment ponds are in place as previously approved by the Division <br />and have been treating disturbed area surface water runoff under the <br />existing permit for the HG Mine. These ponds are the Truck Loop Pond <br />(Pond A) and Railway Loop Pond (Pond B). Both ponds have performed <br />well over this period. The Truck Loop Pond was fitted with a sepazate <br />secondary spillway in 1992 (A sepazate secondary spillway was not <br />necessary for the Rail Loop Pond due to the size and configuration of its <br />single spillway). Designs for these ponds are included in Volume 2, Tab <br />12, Appendix 12-1 and locations of the ponds are displayed on Exhibit 12- <br />2 of the permit application. <br />E. Acid-forming and Toxic-forming_Spoil <br />No coal is being mined at the site therefore there is no acid-forming or toxic- <br />forming spoil. Prior to backfilling the site, all debris and coal fines will be <br />disposed of in a manner that will prevent contamination of surface and ground <br />water <br />F. Impoundments <br />No impoundments other than sediment structures are proposed. <br />G. Ground and Surface Water Monitoring <br />Information on Surface and Ground Water Monitoring is found in Volume 2, <br />Tab 13 of the permit application. Please refer to Figure 2 of this document for <br />the locations of all ground and surface water monitoring sites. <br />Ground Water Monitoring Plan <br />The applicant will conduct monitoring of ground water in a manner <br />approved by the Division. Baseline data was collected in 1977 and 1978 <br />with construction of the facility beginning in 1977. The ground water <br />monitoring plan currently in operation at the loadout consists of taking <br />samples in the spring and fall from well HGDAL 3, which is completed in <br />Dry Creek alluvium downstream from the loadout's facilities (4.05.13(1)). <br />The list of parameters analyzed is found in Table 13-2 of Tab 13. <br />Surface Water Monitoring Plan <br />2. The applicant has and will continue to conduct monitoring of surface <br />water in a manner approved by the Division. The current monitoring <br />regime began in 1985 one yeaz before shipments ceased at the HG <br />i~ <br />
