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. Permits for miscellaneous units
shall contain such terms and provisions as necessary to protect human health
and the environment, including, but not limited to, as appropriate, design and
operating requirements, detection and monitoring requirements, and requirements
for responses to releases of hazardous waste or hazardous waste constituents
from the unit. Permit terms and provisions shall include those requirements of
articles 9 through 15 and articles 27, 28 and 28.5 of this chapter, chapter 20,
40 CFR Part 146, and article 5.5 of chapter 6.5 of division 20 of the Health
and Safety Code (commencing with section 25100) that are appropriate for the
miscellaneous unit being permitted. Protection of human health and the
environment includes, but is not limited to:
(a) prevention of any releases that may have
adverse effects on human health or the environment due to migration of waste
constituents, hazardous constituents, or reaction products, in the ground water
or subsurface environment, considering:
(1)
the volume and physical and chemical characteristics of the waste in the unit,
including its potential for migration through soil, liners, or other containing
structures;
(2) the hydrologic and
geologic characteristics of the unit and the surrounding area;
(3) the existing quality of ground water and
soil-pore liquid and gas, including other sources of pollution and
contamination and their cumulative impact on the ground water and the normally
unsaturated zone;
(4) the quantity
and direction of groundwater flow;
(5) the proximity to and withdrawal rate of
current and potential groundwater users;
(6) the patterns of land use in the
region;
(7) the potential for
deposition or migration of waste constituents, hazardous constituents, or
reaction products, into subsurface physical structures, and into the root zone
of food-chain crops and other vegetation;
(8) the potential for health risks caused by
human exposure to constituents of concern; and
(9) the potential for damage to domestic
animals, wildlife, crops, vegetation, and physical structures caused by
exposure to constituents of concern;
(b) prevention of any releases that may have
adverse effects on human health or the environment due to migration of waste
constituents, hazardous constituents, or reaction products, in surface water,
or wetlands or on the soil surface considering:
(1) the volume and physical and chemical
characteristics of the waste in the unit;
(2) the effectiveness and reliability of
containing, confining, and collecting systems and structures in preventing
migration;
(3) the hydrologic
characteristics of the unit and the surrounding area, including the topography
of the land around the unit;
(4)
the patterns of precipitation in the region;
(5) the quantity, quality, and direction of
ground-water flow;
(6) the
proximity of the unit to surface waters;
(7) the current and potential uses of nearby
surface waters and any water quality standards established for those surface
waters;
(8) the existing quality of
surface waters and surface soils, including other sources of pollution and
contamination and their cumulative impact on surface waters and surface
soils;
(9) the patterns of land use
in the region;
(10) the potential
for health risks caused by human exposure to constituents of concern;
and
(11) the potential for damage
to domestic animals, wildlife, crops, vegetation, and physical structures
caused by exposure to constituents of concern;
(c) prevention of any release that may have
adverse effects on human health or the environment due to migration of waste
constituents, hazardous constituents, or reaction products, in the air,
considering:
(1) the 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;
(2) the effectiveness and reliability of
systems and structures to reduce or prevent emissions of hazardous constituents
to the air;
(3) the operating
characteristics of the unit;
(4)
the atmospheric, meteorologic, and topographical characteristics of the unit
and the surrounding area;
(5) the
existing quality of the air, including other sources of pollution and
contamination and their cumulative impact on the air;
(6) the potential for health risks caused by
human exposure to constituents of concern; and
(7) the potential for damage to domestic
animals, wildlife, crops, vegetation, and physical structures caused by
exposure to constituents of concern.
