(a) Requirement. A person or municipality operating a construction/demolition waste landfill shall prepare and submit to the Department a groundwater assessment plan within 60 days after one of the following occurs:
(1) Data obtained from monitoring by the Department or the operator indicates groundwater degradation at a monitoring point.
(2) Laboratory analysis of one or more public or private water supplies shows the presence of degradation that could reasonably be attributed to the facility.
(b) Exceptions. The operator is not required to conduct an assessment under this section if one of the following applies:
(1) Within 10 working days after receipt of sample results showing groundwater degradation the operator resamples the affected wells and analysis from resampling shows to the Department’s satisfaction that groundwater degradation has not occurred.
(2) Within 20 working days after receipt of sample results indicating groundwater degradation, the operator demonstrates that the degradation was caused entirely by earthmoving and other activities related to facility construction, or by seasonal variations.
(c) The groundwater assessment plan shall specify the manner in which the operator will determine the existence, quality, quantity, aerial extent and depth of groundwater degradation, and the rate and direction of migration of contaminants in the groundwater. A groundwater assessment plan shall be prepared by an expert in the field of hydrogeology. The plan shall contain, at a minimum, the following information:
(1) The number, location, size, casing type and depth of wells, lysimeters, borings, pits, piezometers and other assessment structures or devices to be used. If the operator establishes compliance points as part of the assessment, the points shall be wells constructed in accordance with § § 277.282 and 277.283 (relating to number, location and depth of monitoring points; and standards for wells and casing of wells).
(2) Sampling and analytical methods for the parameters to be evaluated.
(3) Evaluation procedures, including the use of previously gathered groundwater quality information, to determine the concentration, rate and extent of groundwater degradation from the facility.
(4) An implementation schedule.
(5) Identification of the abatement standard that will be met.
(d) The groundwater assessment plan shall be implemented upon approval by the Department under the approved implementation schedule, and shall be completed in a reasonable time not to exceed 6 months unless otherwise approved by the Department. If the Department determines that the proposed plan is inadequate, it may modify the plan and approve the plan as modified. The operator shall notify, in writing, each owner of a private or public water supply located within 1/2-mile downgradient of the disposal area that an assessment has been initiated.
(e) Within 45 days after the completion of the groundwater assessment plan, the operator shall submit a report containing the new data collected, analysis of the data and recommendations on the necessity for abatement.
(f) If the Department determines after review of the groundwater assessment report that implemenation of an abatement plan is not required by § 277.287 (relating to abatement plan), the operator shall submit a permit modification application under § 271.222 (relating to permit modification) for necessary changes to the groundwater monitoring plan. The operator shall implement the modifications within 30 days of the Department’s approval.
(g) This section does not prevent the Department from requiring, or the operator from conducting, groundwater abatement or water supply replacement concurrently with, or prior to, implementation of the assessment.

(1) The groundwater assessment plan prepared and implemented under § 277.286 (relating to groundwater assessment plan) shows the presence of groundwater degradation at one or more monitoring wells and the analysis under § 277.286(c) indicates that an abatement standard under subsection (d) will not be met.
(2) Monitoring by the Department or operator shows the presence of an abatement standard exceedance from one or more compliance points as indicated in subsection (d), even if a groundwater assessment plan has not been completed. The operator is not required to implement an abatement plan under this paragraph if the following are met:
(i) Within 10 days after receipt of sample results showing an exceedance of an abatement standard, at a point of compliance described in subsection (d), the operator resamples the affected wells.
(ii) Analysis from resampling shows to the Department’s satisfaction that an exceedance of an abatement standard has not occurred.
(b) An abatement plan shall be prepared by an expert hydrogeologist and submitted to the Department. The plan shall contain the following information:
(1) The specific methods or techniques to be used to abate groundwater pollution from the facility.
(2) The specific methods or techniques to be used to prevent further groundwater pollution from the facility.
(c) The abatement plan shall be completed and submitted to the Department for approval within 90 days of the time the obligation arises under this section unless the date is otherwise modified, in writing, by the Department.
(d) If abatement is required in accordance with subsection (a), the operator shall demonstrate compliance with one of the following abatement standards at and beyond 150 meters of the perimeter of the permitted disposal area or at and beyond the property boundary, whichever is closer:
(1) For constituents for which an MCL has been promulgated under the Federal Safe Drinking Water Act or the Pennsylvania Safe Drinking Water Act (42 U.S.C.A. § § 300f—300j-18; and 35 P. S. § § 721.1—721.17), the MCL for that constituent.
(2) For constituents for which MCLs have not been promulgated, the background standard for the constituent.
(3) For constituents for which the background standard is higher than the MCL or risk-based standard identified under paragraph (4), the background standard.
(4) For constituents for which no MCLs have been established, the risk-based standard if the following conditions are met:
(i) The risk assessment used to establish the standard assumes that human receptors exist at the property boundary.
(ii) The level is derived in a manner consistent with Department guidelines for assessing the health risks of environmental pollutants.
(iii) The level is based on scientifically valid studies conducted in accordance with good laboratory practice standards (40 CFR Part 792 (relating to good laboratory practice standards)) promulgated under the Toxic Substances Control Act (15 U.S.C.A. § § 2601—2692) or other scientifically valid studies approved by the Department.
(iv) For carcinogens, the level represents a concentration associated with an excess lifetime cancer risk level of 1.0 x 10-5 at the property boundary.
(v) For systemic toxicants, the level represents a concentration to which the human population (including sensitive subgroups) could be exposed on a daily basis that is likely to be without appreciable risk of deleterious effects during a lifetime. For purposes of this subparagraph, systemic toxicants include toxic chemicals that cause effects other than cancer or mutation.
(e) Within 60 days of approval by the Department, the operator shall commence implementation of the plan, under the approved implementation schedule. If the Department determines that the proposed plan is inadequate, it may modify the plan and approve the plan as modified.
(f) The abatement plan shall be continued until the Department states in writing, based on monitoring by the Department and the operator, that groundwater pollution from the facility has been permanently abated.
