Current through Register Vol. 48, No. 28, July 12, 2024
a) Community water
				supplies which meet all of the requirements specified in Ill. Rev. Stat. 1983,
				ch. 111 1/2, par. 1017(b) (as amended) shall be exempt from chlorination upon
				approval by the Agency of an application for exemption. Applications and
				approvals shall be in writing.
b)
				The decision to issue an exemption shall be based on the following:
1) The population served by the community
				water supply does not exceed 5000 based upon the latest census figures or
				complete records of number of individuals served.
2) The supply shall have as its only source
				of raw water, one or more wells constructed in accordance with Section
				653.103 into
				confined geologic formations not subject to contamination. Verification will be
				based on driller's log, visual inspection of the well(s), general geology of
				the area and results of bacteriological analyses performed on raw water
				samples. Supplies which do not have this data may apply for an exemption as
				long as sample results verify satisfactory raw water quality which complies
				with 35 Ill. Adm. Code Part 604.
3)
				The supply shall not have a history of persistent or recurring contamination as
				indicated by sampling results which show violation of finished water quality
				requirements for the most recent five year period. Verification will be based
				on review of the last five years of sample results; the most recent 12 months
				will be weighted more heavily. New supplies without this data may apply for an
				exemption based on available samples.
4) The supply shall not provide any raw water
				treatment other than fluoridation. Treatment will be verified by facility
				inspection.
5) The supply shall
				have an active program in accordance with Section
				653.801
				approved in writing by the Agency to educate water supply customers on
				preventing the entry of contaminants into the water system. An outline of the
				program and copies of handouts to be used shall be sent to the Agency with the
				exemption application.
6) The
				supply shall employ on its operational staff a certified operator of the proper
				class. A community water supply which is exempt from the requirement for a
				certified operator in accordance with Ill. Rev. Stat. 1983, ch. 111 1/2, par.
				509 (as amended) shall employ on its operational staff a registered person in
				responsible charge of operation of the community water supply. Verification of
				certified operator or registered person shall be made by checking Notification
				of Certified Operator in Responsible Charge forms or Registration of Person in
				Responsible Charge forms on file in Agency records.
7) The supply shall submit samples for
				microbiological analysis at twice the frequency required for non-exempt
				supplies. Compliance with this requirement shall be verified using Agency
				monitoring records.
8) A unit of
				local government seeking to exempt its community water supply from the
				chlorination requirement shall receive approval of the voters of that local
				government in accordance with Ill. Rev. Stat. 1983, ch. 111 1/2, par.
				1017(b)(8) (as amended). A certified copy of the results of the proposition
				shall be filed with the Division of Public Water Supplies.
