Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 704 - UIC PERMIT PROGRAM › Subpart I - REQUIREMENTS FOR CLASS V INJECTION WELLS › Section 704.281 - Examples of Class V Injection Wells

Current through Register Vol. 48, No. 28, July 12, 2024
The following are examples of Class V injection wells to
				  which this Subpart I applies:
a) Air
				conditioning return flow wells used to return to the supply aquifer the water
				used for heating or cooling in a heat pump;
b) A large capacity cesspool, including a
				multiple-dwelling, community, or regional cesspool, or any other device that
				receives sanitary wastes containing human excreta that has an open bottom and,
				sometimes, perforated sides. The UIC requirements do not apply to a single
				family residential cesspool, nor do they apply to a non-residential cesspool
				that receives solely sanitary waste and which has the capacity to serve fewer
				than 20 persons a day;
c) A cooling
				water return flow well that is used to inject water previously used for
				cooling;
d) A drainage well that is
				used to drain surface fluids, primarily storm runoff, into a subsurface
				formation;
e) A dry well that is
				used for the injection of wastes into a subsurface formation;
f) A recharge well that is used to replenish
				the water in an aquifer;
g) A salt
				water intrusion barrier well that is used to inject water into a fresh aquifer
				to prevent the intrusion of salt water into the fresh water;
h) A sand backfill and other backfill well
				that is used to inject a mixture of water and sand, mill tailings, or other
				solids into mined out portions of a subsurface mine, whether what is injected
				is a radioactive waste or not;
i) A
				septic system well that is used to inject the waste or effluent from a multiple
				dwelling, business establishment, community, or regional business establishment
				septic tank. The UIC requirements do not apply to a single family residential
				septic system well, nor to a non-residential septic system well that is used
				solely for the disposal of sanitary waste and which has the capacity to serve
				fewer than 20 persons a day;
j) A
				subsidence control well (not used for the purpose of oil or natural gas
				production) that is used to inject fluids into a non-oil-and-gas-producing zone
				to reduce or eliminate subsidence associated with the overdraft of fresh
				water;
k) An injection well
				associated with the recovery of geothermal energy for heating, aquaculture, and
				production of electric power;
l) A
				well that is used for solution mining of conventional mines, such as stopes
				leaching;
m) A well that is used to
				inject spent brine into the same formation from which it was withdrawn after
				extraction of halogens or their salts;
n) An injection well that is used in
				experimental technologies;
o) An
				injection well that is used for in-situ recovery of lignite, coal, tar sands,
				and oil shale; and
p) A motor
				vehicle waste disposal well that receives or which has received fluids from
				vehicular repair or maintenance activities, such as an auto body repair shop,
				an automotive repair shop, a new or used car dealership, a specialty repair
				shop (e.g., transmission and muffler repair shop), or any facility that does
				any vehicular repair work. Fluids disposed in this type of well may contain
				organic and inorganic chemicals in concentrations that exceed the maximum
				contaminant levels (MCLs) established by the primary drinking water regulations
				(35 Ill. Adm. Code 611). These fluids also may include waste petroleum products
				and may contain contaminants, such as heavy metals and volatile organic
				compounds, that pose risks to human health.
