Therefore, coal mining operators are responsible for maintaining passive treatment technologies in accordance with the Pollution Abatement Plan until the appropriate SMCRA authority has authorized bond release. TMDL analyses have identified drainage emanating from abandoned mine land as the source of pollutants inhibiting attainment of water quality standards for thousands of stream miles.
III 1999 Oxic limestone drains for treatment of dilute, acidic discharges [abs. Coffee Break 10:50 — 11:20 a. These latter four sites were either mined very slowly, had nonrepresentative ABA data, received water from an adjacent underground mine, or had a surface mining practice that degraded the water. Other States and mine operators have suggested that self inspections be conducted quarterly and after significant precipitation events. Specifically, to the extent that existing sources have already incurred costs associated with installing sedimentation ponds, new sources would be able to avoid such costs.
The procedures in Appendix B apply to the Coal Remining Subcategory. These technologies are projected to increase the volume of storm water drainage to arid watersheds and avoid the disturbance of approximately 600 acres per year, thus reducing severe erosion, sedimentation, hydrologic imbalance, and water loss.
EPA proposed to define coal remining as the mining of surface mine lands, underground mine lands, and coal refuse piles that were abandoned prior to the enactment of the Surface Mining Reclamation and Control Act August 3, 1977consistent with the language of the Rahall Amendment to the Clean Water Act.

Spoil piles are areas where overburden is placed prior to regrading and revegetating. The IMCC Remining Task Force believes that BMPs can result in improved water quality and, in certain cases, can qualify as BAT for achieving standards required by the Clean Water Act. Acid mine drainage AMD is a worldwide concern in coal and metal mining.American Society for Surface Mining and Reclamation, p.
For example, implementation of appropriate BMPs during 112 remining operations in Pennsylvania has been effective in improving or eliminating acidity loading in 45 percent of the pre-existing discharges, total iron loading in 44 percent of the discharges, and total manganese in 42 percent of the discharges.
Economic Impacts of the Final Rule 1. However, EPA would like to further clarify this statement of applicability for the Coal Remining Subcategory. Section 301 p requires the operator to demonstrate that the coal remining operation will result in the potential for improved water quality, and in no event may pH, iron, or manganese discharges exceed the levels discharged prior to the remining operation.
The models estimated capital costs design, construction and removal of ponds and implementation of BMPs and operating costs inspection, maintenance, and operation over the anticipated bonding period.
