Current through Register Vol. 51, No. 14, July 12, 2024
A. Applicability.
				  This regulation applies to persons seeking or required to obtain a controlled
				  hazardous substances (CHS) facility permit to manage hazardous waste in a
				  regulated unit, as defined in COMAR
				  26.13.05.06 s A(2)(b).
B. Except as otherwise provided in COMAR
				  26.13.05.06 s A(3), a person
				  subject to this regulation shall provide the following additional information
				  regarding protection of ground water as a part of the permit application:
(1) A summary of the ground water monitoring
				  data obtained from the requirements of COMAR
				  26.13.05.06 s A-E, when
				  applicable;
(2) Identification of
				  the uppermost aquifer and aquifers hydraulically interconnected beneath the
				  facility property, including ground water flow direction and rate, and the
				  basis for the identification, such as the information obtained from
				  hydrogeologic investigation of the facility area;
(3) On the topographic map required under
				  Regulation .02D(6) of this chapter, a delineation of the waste management area,
				  the property boundary, the proposed point of compliance as defined under COMAR
				  26.13.05.06 s -1D, the proposed
				  location of ground water monitoring wells as required under COMAR
				  26.13.05.06 s -2 and, to the
				  extent possible, the information required in §B(2) of this
				  regulation;
(4) A description of
				  any plume of contamination that has entered the ground water from a regulated
				  unit at the time the application is submitted that:
(a) Delineates the extent of the plume on the
				  topographic map required under Regulation .02D(6)(b) of this chapter;
				  and
(b) Identifies the
				  concentration of each constituent from Appendix IX Ground Water Monitoring List
				  of 40 CFR Part 264, which is incorporated by reference in COMAR
				  26.13.01.05 s B(1)(c), throughout
				  the plume, or identifies the maximum concentrations of each constituent in the
				  plume;
(5) Detailed
				  plans and an engineering report describing the proposed ground water monitoring
				  program to be implemented to meet the requirements of COMAR
				  26.13.05.06 s -2;
(6) If the presence of hazardous constituents
				  has not been detected in the ground water at the time of permit application,
				  sufficient information, supporting data, and analyses to establish a detection
				  monitoring program which meets the requirements of COMAR
				  26.13.05.06 s -4, including:
(a) A proposed list of indicator parameters,
				  waste constituents, or reaction products that can provide a reliable indication
				  of the presence of hazardous constituents in the ground water;
(b) A proposed ground water monitoring
				  system;
(c) Background values for
				  each proposed monitoring parameter or constituent, or procedures to calculate
				  these values; and
(d) A description
				  of proposed sampling analysis and statistical comparison procedures to be used
				  in evaluating ground water monitoring data;
(7) The following information if the presence
				  of hazardous constituents has been detected in the ground water at the point of
				  compliance at the time of permit application:
(a) Sufficient information, supporting data,
				  and analyses to establish a compliance monitoring program which meets the
				  requirements of COMAR
				  26.13.05.06 s -5;
(b) An engineering feasibility plan for a
				  corrective action program necessary to meet the requirements of COMAR
				  26.13.05.06 s -6, except as
				  provided by COMAR
				  26.13.05.06 s -4H(5), unless the
				  permit applicant obtains written authorization in advance from the Secretary to
				  submit a proposed permit schedule for submittal of the plan; and
(c) The following items to demonstrate
				  compliance with COMAR
				  26.13.05.06 s -5:
(i) A description of the wastes previously
				  handled at the facility;
(ii) A
				  characterization of the contaminated ground water, including concentrations of
				  hazardous constituents;
(iii) A
				  list of hazardous constituents for which compliance monitoring will be
				  undertaken in accordance with COMAR
				  26.13.05.06 s -2 and
				  .06-5;
(iv) Proposed concentration
				  limits for each hazardous constituent, based on the criteria set forth in COMAR
				  26.13.05.06 s -1C, including a
				  justification for establishing any alternate concentration limits;
(v) Detailed plans and an engineering report
				  describing the proposed ground water monitoring system, in accordance with the
				  requirements of COMAR
				  26.13.05.06 s -2; and
(vi) A description of proposed sampling,
				  analysis, and statistical comparison procedures to be used in evaluating ground
				  water monitoring data.
