Exceptions to effluent limitations include the following: (1) The pH of the discharges shall be maintained between 6.0 and 9.0, except in the following circumstances: (i) Where the wastes are discharges to an acid stream, in which cases the pH may be greater than 9.0. (ii) When the discharger affirmatively demonstrates to the Department that the wastewater treatment process being used by the discharger requires the pH to be raised above 9.0, that the elevated pH will not cause a safety hazard at the outfall and that the elevated pH will not result in a violation of applicable water quality standards in Chapter 93 (relating to water quality standards) or of the applicable treatment requirements and effluent limitations to which a discharge is subject under the Clean Water Act (33 U.S.C.A. Secs. 1251 1376) the Department may grant a variance from this limitation. (2) When a discharge without chemical or biological treatment has a pH greater than 6.0 and a total iron concentration of less than 10.0 mg/l, the manganese limitation does not apply. (d) SINGLE FACILITIES USED FOR SEDIMENT AND EROSION CONTROL. If a single facility is used for sediment and erosion control facilities and treatment facilities covered by this section, the concentration of each pollutant in the combined discharge may not exceed the most stringent limitations for that pollutant applicable to a component waste stream of the discharge. (e) POSTMINING POLLUTIONAL DISCHARGES. (1) If a postmining pollutional discharge occurs, the discharger shall immediately provide interim treatment to comply with the Group A effluent requirements in subsection (a), including modifications authorized or required under subsection ( c), (d) or (f). The discharger shall also take whatever measures are necessary and available to abate the discharge, including modifying the operation and reclamation plan for the mining activity. (2) If the discharge continues to exist, after implementation of the abatement measures required under paragraph (1), the discharger shall make provisions for sound future treatment of the discharge to achieve the Group A effluent requirements in subsection (a), including modifications authorized or required under subsection ( c) or (f).

Discharges which can be adequately treated using a passive treatment system include, but are not limited to: (i) Discharges with a pH which is always greater than 6.0 and an alkalinity which always exceeds the acidity. (ii) Discharges with an acidity which is always less than 100 milligrams per liter, an iron content which is always less than 10 milligrams per liter, a manganese content which is always less than 18 milligrams per liter and a flow rate which is always less than 3 gallons per minute. (iii) Discharges with a net acidity always less than 300 milligrams per liter which is calculated by subtracting the alkalinity of the discharge from its acidity. (3) A passive treatment system authorized under paragraph (2) shall comply with the following effluent requirements: (i) The system shall reduce the iron concentration by at least 90% or by that percentage necessary to achieve the Group A effluent requirements in subsection (a), whichever percentage is less. (ii) The system shall produce an effluent alkalinity which exceeds effluent acidity. (4) In addition to achieving the effluent requirements of paragraphs (2) and (3), the passive treatment system shall be designed and constructed to accomplish the following: (i) Prevent discharge of mine drainage into the groundwater. (ii) Prevent extraneous sources of groundwater and surface water runoff from entering the treatment system. (iii) Hydraulically handle the highest average monthly flow rate which occurs during a 12-month period. (iv) Have inlet and outlet structures which will allow for flow measurement and water sampling.

Upon completion of the associated surface mining activities, the area disturbed by the road shall be restored in accordance with Sec. 88.341 (relating to haul roads and access roads: restoration) unless retention of the road and its maintenance plan is approved as part of the postmining land use. (b) The haul road may not be located in or within 100 feet of a perennial or intermittent stream except in accordance with Sec. 86.102 (relating to areas where mining is prohibited or limited). Any crossing of a perennial or intermittent stream shall be made using bridges, culverts or similar structures. Bridges, culverts or other encroachment or water obstruction shall meet the requirement of Chapter 105 (relating to dam safety and waterway management). ( c) Each road shall have a drainage system that is compatible with the natural drainage system, structurally stable and which will pass safely the peak flow from a 10-year precipitation event or larger event if required by the Department. The drainage system shall include sloped or crowned road surface, cross drains or culverts, stabilized ditches, erosion resistant surfacing, sediment traps and other appropriate control measures as required by Sec. 88.296 (relating to hydrologic balance: sediment control measures). (d) Roads shall be constructed on stable areas that avoid wet or unsuitable soils. (e) Prior to the construction of the road, all topsoil shall be removed, stored on a stable site and protected against erosion and compaction until restoration of the haul road. (f) Any disturbed area adjacent to the road shall be vegetated or otherwise stabilized to prevent erosion. (g) Acid or toxic-forming material may not be used for surfacing or construction of a road except where the road is within the confines of a coal refuse disposal or reprocessing area and the effluent meets the requirements of Sec. 88.292 (relating to hydrologic balance: effluent standards).
