Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 611 - PRIMARY DRINKING WATER STANDARDS › Subpart O - ORGANIC MONITORING AND ANALYTICAL REQUIREMENTS › Section 611.640 - Definitions

Current through Register Vol. 48, No. 28, July 12, 2024
The following terms are defined for use in this Subpart O
				  only. Additional definitions are located in Section
				  611.102.
"Old MCL" means an MCL in Section
				  611.310.
				  These include the MCLs identified as "additional state requirements". "Old
				  MCLs" include the Section
				  611.310
				  MCLs for the following contaminants:
Aldrin
2,4-D
DDT
Dieldrin
Heptachlor
Heptachlor epoxide
BOARD NOTE: 2,4-D, heptachlor, and heptachlor epoxide are
				  also "Phase II SOCs". The additional state requirements of Section
				  611.310
				  impose a more stringent "old MCL" for each of these compounds than that imposed
				  on them as Phase II SOCs by Section
				  611.311.
				  However, the requirements for sampling and monitoring for these compounds as
				  Phase II SOCs and the consequences of their detection and violation of their
				  revised MCLs is more stringent as Phase II SOCs.
"Phase II SOCs" means the following:
Alachlor
Atrazine
Carbofuran
Chlordane
Dibromochloropropane
Ethylene dibromide
Heptachlor
Heptachlor epoxide
Lindane
Methoxychlor
Polychlorinated biphenyls
Toxaphene
2,4-D
2,4,5-TP
BOARD NOTE: These are organic contaminants regulated at
				  40 CFR
				  141.61(c)(1) through (c)(18)
				  (2016). The MCLs for these contaminants are located at Section 611.311. More
				  stringent MCLs for heptachlor, heptachlor epoxide, and 2,4-D are found as
				  "additional state requirements" in Section 611.310.
"Phase IIB SOCs" means the following:
Aldicarb
Aldicarb Sulfone
Aldicarb Sulfoxide
Pentachlorophenol
BOARD NOTE: These are organic contaminants regulated at
				  40 CFR
				  141.61(c)(1) through (c)(18)
				  (2016). The MCLs for these contaminants are located at Section 611.311. See the
				  Board note appended to Section
				  611.311(c)
				  for information relating to implementation of requirements relating to
				  aldicarb, aldicarb sulfone, and aldicarb sulfoxide.
"Phase V SOCs" means the following:
Benzo(a) pyrene
Dalapon
Di(2-ethylhexyl)adipate
Di(2-ethylhexyl)phthalate
Dinoseb
Diquat
Endothall
Endrin
Glyphosate
Hexachlorobenzene
Hexachlorocyclopentadiene
Oxamyl
Picloram
Simazine
2,3,7,8-TCDD
BOARD NOTE: These are organic contaminants regulated at
				  40 CFR
				  141.61(c)(19) through
				  (c)(33) (2016). The MCLs for these
				  contaminants are located at Section 611.311.
"Phase I VOCs" means the following:
Benzene
Carbon tetrachloride
p-Dichlorobenzene
1,2-Dichloroethane
1,1-Dichloroethylene
1,1,1-Trichloroethane
Trichloroethylene
Vinyl chloride
BOARD NOTE: These are the organic contaminants regulated at
				  40 CFR
				  141.61(a)(1) through (a)(8)
				  (2016). The MCLs for these contaminants are located at Section
				  611.311(a).
"Phase II VOCs" means the following:
o-Dichlorobenzene
cis-1,2-Dichloroethylene
trans-1,2-Dichloroethylene
1,2-Dichloropropane
Ethylbenzene
Monochlorobenzene
Styrene
Tetrachloroethylene
Toluene
Xylenes (total)
BOARD NOTE: These are organic contaminants regulated at
				  40 CFR
				  141.61(a)(9) through (a)(18)
				  (2016). The MCLs for these contaminants are in Section
				  611.311(a).
"Phase V VOCs" means the following:
Dichloromethane
1,2,4-Trichlorobenzene
1,1,2-Trichloroethane
BOARD NOTE: These are the organic contaminants regulated at
				  40 CFR
				  141.61(a)(19) through
				  (a)(21) (2016). The MCLs for these
				  contaminants are located at Section
				  611.311(a).
"Revised MCL" means an MCL in Section 611.311. This term
				  includes MCLs for Phase I VOCs, Phase II VOCs, Phase V VOCs, Phase II SOCs,
				  Phase IIB SOCs, and Phase V SOCs.
