• Dimension and composition of any and all Floors and footings In addition, the operator will need to specify a plan to ensure surface water and groundwater will not be impacted from operations at the Plant Site. 3. The applicant states that on site roads will not be improved unless used as a haul routes, and most of the roads will remain when mining ends to allow access to oil well facilities on the site. Please specify the increase in width of the existing roads. In addition, the improved roads and new roads will need to be downsized to achieve the purpose of the postmining land use of recreation and wildlife habitat. The applicant will need to specify the width of the improved road, the width of the road proposed for reclamation, and the overall length of the roads to be improved and reclaimed. This will be taken into account in the reclamation cost estimate. Please also specify how roads will be improved to ensure [ha[ the oil production lines will be protected from use of haul truck and truck traffic. Please specify the depth of oil line below the ground surface and the thickness of road base material to be placed on the roads. 4. The applicant states that if PS&G chooses [o seal one of [he lakes, fill it with water [hey purchase/own and use it for recreation it does not change the final reclamation plan. Lakes that are lined either by slurry wall or compacted clay liners for the purpose of storing water does change the end land use to developed water resources. Such change would require an amendment to the permit. Please also be aware that backfilling with inert material and lack of compacted pit slopes may require a greater off set distance for the location of the slurrywall or the need of additional compaction of the backfilled pit. All of these issues will need [o be addressed through [he amendment process. 5. The applicant states that the area of dewatering will be limited to 5-acres or less in each lake area as far from the permit boundary as possible. The report prepared by LEONARD RICE CONSULTING WATER ENGINEERS, INC. evaluates the potential impacts to nearby wells in terms of lowered water levels resulting from the dewatering of 1-acre pit sites for dredge construction. The operator clarified this discrepancy by letter on March 30, 2001. In addition, the applicant states that LEONARD RICE CONSULTING WATER ENGINEERS, INC. is also working on a long term plan that may involve building and/or installing a water recharge ditch/lake up gradient from the dewatered area that would act as a recharge barrier and allow dewatering on larger areas in the mine. This report will need to be submitted as a revision to the permit. [n fact, any dewatering area lazger than one acre in size will need to be approved by the Division in the form of a revision to the permit. 6. The applicant provided additional information regarding inert materials that may be hauled into the site and used to reclaim the pit slopes. The Division will need some additional information on the importation of inert fill; Please specify the size and gradation of the material to be placed in the pit. The cover material and depth to be placed over the inert material (6" replacement depth as stated in application is not acceptable). On site controls, monitoring and recording methods to insure that the material is indeed inert material. In addition, the placement of the inert material using heavy equipment does not seem feasible if the area is to be wet mined. Please specify how the inert material will be placed as backfilled material under the current mining conditions to achieve the reclaimed slopes of 2h:ly and 3h:ly 10 feet below and 5 feet above the expected water line.
