(Identical-in-Substance
Rulemaking - Public Water Supply)
Adopted Rule. Final Order.
OPINION AND ORDER OF THE BOARD (by R.C. Flemal):
The Board today updates its regulations that are identical in substance to the United
States Environmental Protection Agency’s (USEPA) regulations implementing the Safe
Drinking Water Act (SDWA) (42 U.S.C § 300f
et seq.
(1996)). 415 ILCS 5/17.5 (1996).
The Board rules are contained in 35 Ill. Adm. Code 611. The text of the proposed rules
appears in the order segment of this document.
Section 17.5 of the Environmental Protection Act (Act) provides for quick adoption of
regulations that are identical in substance to federal regulations. Section 17.5 provides that
Title VII of the Act and Section 5 of the Administrative Procedure Act (APA) (5 ILCS 100/5-
35, 5-45 (1996)) does not apply. Because this rulemaking is not subject to Section 5 of the
APA, it is not subject to first notice requirements or second notice review by the Joint
Committee on Administrative Rules (JCAR). On December 4, 1997, the Board adopted a first
notice proposal for publication in the
Illinois Register
whereupon a 45-day comment period
commenced. 21 Ill. Reg. 16956 (December 26, 1997).
As discussed more fully below, this rulemaking involves revisions to Part 611
regarding radiological monitoring and analytical requirements. It includes corrections to the
federal rules, as adopted by the USEPA on March 5, 1997, (62 Fed. Reg. 10168 (March 5,
1997)) that affect the implementation of those rules.
PUBLIC COMMENTS
The public comment period closed on February 9, 1998. One public comment (PC 1)
was filed by Connie L. Tonsor, on behalf of the Illinois Environmental Protection Agency.
The Agency requests that the Board make several nonsubstantive grammatical corrections to
Sections 611.102 and 611.720 for clarification purposes. PC 1 at 2-4. In addition, the
Agency asks that the Board delete all references to the HASL Procedure Manual in Sections
611.102 and 611.720. PC 1 at 1-4.
The Board agrees with the Agency that its suggested nonsubstantive grammatical
changes are necessary to clarify the incorporations by reference and the analytical methods set
2
forth in Sections 611.102 and 611.720, respectively. Accordingly, the Board makes those
changes suggested by the Agency.
As for the Agency’s request that the Board delete all references to the HASL Procedure
Manual, the Board declines such request. The Board notes that Section 611.102 is derived
from 40 CFR, Appendix B and C (1995). Further, Section 611.720 is derived from 40 CFR
141.25(a) (1995). In addition, other sections in the federal regulations, namely 40 CFR
141.25(b), still reference the HASL Procedure Manual. Section 17.5 of the Act requires the
Board to adopt regulations that are identical in substance to federal regulations. If the Board
were to delete the references to the HASL Procedure Manual in the aforementioned sections, it
would create a situation where Illinois’ regulations are no longer identical in substance to the
corresponding federal regulations. The Board therefore declines to make these changes until it
receives further interpretation from the federal government regarding the applicability of the
HASL Procedure Manual.
Accordingly, apart from the nonsubstantive grammatical changes suggested by the
Agency, the Board proceeds to adoption of the amendments as proposed on December 4,
1997. See Safe Drinking Water Act Update, USEPA Amendments to Part 611 (January 1,
1997 through June 30, 1997) December 4, 1997, R98-2.
SUMMARY OF THE PROPOSED AMENDMENTS
The adopted amendments approve the use of 66 additional analytical methods for
compliance with current radionuclide drinking water standards and monitoring requirements.
The methods are applicable to gross alpha, gross beta, tritium, uranium, radium-226, radium-
228, gamma emitters, and radioactive cesium, iodine, and strontium. Entities potentially
regulated by this action are public water systems that have at least 15 service connections or
regularly serve an average of at least 25 individuals daily at least 60 days out of the year.
The SDWA, as amended in 1996, requires USEPA to promulgate national primary
drinking water regulations (NPDWRs) that specify maximum contaminant levels (MCLs) or
treatment techniques for drinking water contaminants. 42 U.S.C. 300g-1 (1996). NPDWRs
apply to public water systems. 42 U.S.C. 300f(1)(A) (1996).
USEPA has promulgated analytical methods for all currently regulated drinking water
contaminants for which MCLs or monitoring requirements have been promulgated. In most
cases, USEPA has promulgated regulations approving use of more than one analytical method
for measurement of a contaminant, and laboratories may use any approved method for
determining compliance with an MCL or monitoring requirement.
On July 18, 1991 (56 Fed. Reg. 33050 (July 18, 1991)), USEPA proposed to increase
the number of methods approved for radionuclide monitoring by proposing the use of several
new methods. As previously stated, USEPA finalized these rules on March 5, 1997, (62 Fed.
Reg. 10168 (March 5, 1997)).
3
The Board notes that, in Section 611.102(b) (Incorporations by Reference), USEPA
refers to “Standard Methods for the Examination of Water and Wastewater,” (Standard
Methods), 17th edition; however, USEPA does not specifically identify which methods are
found in that particular edition. In the December 4, 1997, proposal, the Board included a
reference to the Standard Methods, 17th edition, in Section 611.102, but invited public
comment regarding which methods specifically are found in the 17th edition. As no such
comments were received, the Board will proceed to final adoption with the reference as
included in the December 4, 1997, proposal. The Board further notes that it has made two
additional nonsubstantive changes in Section 611.102(b) to correct citations to the Code of
Federal Regulations.

D) USEPA Radioactivity Methods: Methods 901, 901.1,
902;
E) USEPA Radiochemical Analyses: page 92; or
G) USGS Methods: Method R-1110-76.
b)
When the identification and measurement of radionuclides other than those
listed in subsection (a) are required, the following methods, incorporated by
reference in Section 611.102, are to be used, except in cases where alternative
methods have been approved in accordance with Section 611.480:
1)
"Procedures for Radiochemical Analysis of Nuclear Reactor Aqueous
Solutions", available from NTIS.
32
2)
HASL Procedure Manual, HASL 300.
c)
For the purpose of monitoring radioactivity concentrations in drinking water,
the required sensitivity of the radioanalysis is defined in terms of a detection
limit. The detection limit must be that concentration which can be counted with
a precision of plus or minus 100 percent at the 95 percent confidence level (1.96
sigma where sigma is the standard deviation of the net counting rate of the
sample).
1)
To determine compliance with Section 611.330(a) the detection limit
must not exceed 1 pCi/L. To determine compliance with Section
611.330(b) the detection limit must not exceed 3 pCi/L.
2)
To determine compliance with Section 611.331 the detection limits must
not exceed the concentrations listed in that Section.
d)
To judge compliance with the MCLs listed in Sections 611.330 and 611.331,
averages of data must be used and must be rounded to the same number of
significant figures as the MCL for the substance in question.
