Code of Maryland Regulations › Title 26 - DEPARTMENT OF ENVIRONMENT › Part 3 - SUBTITLES 13-18 › Subtitle 13 - DISPOSAL OF CONTROLLED HAZARDOUS SUBSTANCES › Chapter 26.13.05 - Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and Disposal Facilities › Section 26.13.05.16-1 - Miscellaneous Units

Current through Register Vol. 51, No. 14, July 12, 2024
A.
				  Applicability. The requirements in this regulation apply to owners and
				  operators of facilities that treat, store, or dispose of hazardous waste in
				  miscellaneous units, except as Regulation .01 of this chapter provides
				  otherwise.
B. Environmental
				  Performance Standards.
(1) A miscellaneous
				  unit shall be located, designed, constructed, operated, maintained, and closed
				  in a manner that will ensure protection of human health and the
				  environment.
(2) Permits for
				  miscellaneous units are to contain such terms and provisions as necessary to
				  protect human health and the environment, including, but not limited to, as
				  appropriate:
(a) Design and operating
				  requirements;
(b) Detection and
				  monitoring requirements;
(c)
				  Requirements for responses to releases of hazardous waste or hazardous
				  constituents from the unit; and
(d)
				  All applicable requirements of Regulations .09 - .14 and .16 of this chapter,
				  and COMAR 26.13.07 that are appropriate for the miscellaneous unit being
				  permitted.
(3) For the
				  purposes of §B(2), of this regulation, protection of human health and the
				  environment includes, but is not limited to, prevention of any releases that
				  may have adverse effects on human health or the environment due to migration of
				  waste constituents in:
(a) The ground water or
				  subsurface environment, considering the:
(i)
				  Volume and physical and chemical characteristics of the waste in the unit,
				  including its potential for migration through soil, liners, or other containing
				  structures;
(ii) Hydrologic and
				  geologic characteristics of the unit and the surrounding area;
(iii) Existing quality of ground water,
				  including other sources of contamination and their cumulative impact on the
				  ground water;
(iv) Quantity and
				  direction of ground water flow;
(v)
				  Proximity to and withdrawal rates of current and potential ground water
				  users;
(vi) Patterns of land use in
				  the region;
(vii) Potential for
				  deposition or migration of waste constituents into subsurface physical
				  structures, and into the root zone of food-chain crops and other
				  vegetation;
(viii) Potential for
				  health risks caused by human exposure to waste constituents; and
(ix) Potential for damage to domestic
				  animals, wildlife, crops, vegetation, and physical structures caused by
				  exposure to waste constituents;
(b) Surface water, wetlands, or on the soil
				  surface, considering the:
(i) Volume and
				  physical and chemical characteristics of the waste in the unit;
(ii) Effectiveness and reliability of
				  containing, confining, and collecting systems and structures in preventing
				  migration;
(iii) Hydrologic
				  characteristics of the unit and the surrounding area, including the topography
				  of the land around the unit;
(iv)
				  Patterns of precipitation in the region;
(v) Quantity, quality, and direction of
				  ground water flow;
(vi) Proximity
				  of the unit to surface waters;
(vii) Current and potential uses of nearby
				  surface waters and any water quality standards established for those surface
				  waters;
(viii) Existing quality of
				  surface waters and surface soils, including other sources of contamination and
				  their cumulative impact on surface waters and surface soils;
(ix) Patterns of land use in the
				  region;
(x) Potential for health
				  risks caused by human exposure to waste constituents; and
(xi) Potential for damage to domestic
				  animals, wildlife, crops, vegetation, and physical structures caused by
				  exposure to waste constituents;
(c) The air, considering the:
(i) Volume and physical and chemical
				  characteristics of the waste in the unit, including its potential for the
				  emission and dispersal of gases, aerosols, and particulates;
(ii) Effectiveness and reliability of systems
				  and structures to reduce or prevent emissions of hazardous constituents to the
				  air;
(iii) Operating
				  characteristics of the unit;
(iv)
				  Atmospheric, meteorologic, and topographic characteristics of the unit and the
				  surrounding area;
(v) Existing
				  quality of the air, including other sources of contamination and their
				  cumulative impact on the air;
(vi)
				  Potential for health risks caused by human exposure to waste constituents;
				  and
(vii) Potential for damage to
				  domestic animals, wildlife, crops, vegetation, and physical structures caused
				  by exposure to waste constituents.
