SUPPLEMENTARY INFORMATION:
Background. EPA approved the State's initial application for PWSS
Program primary enforcement authority (``primacy'') on August 25, 1978
(43 FR 38083). Since initial approval, EPA has approved various
revisions to Arizona's PWSS Program. For the revisions covered by this
action, the EPA promulgated the Stage 1 DBP Rule on December 16, 1998
(63 FR 69390-69476) with revisions to the Stage 1 DBP Rule on January
16, 2001 (66 FR 3770-3780). EPA promulgated the Stage 2 DBP Rule on
January 2, 2006 (71 FR 388-493) and published Stage 2 DBP Rule
corrections on January 27, 2006 (71 FR 4644), June 29, 2006 (71 FR
37168) and November 14, 2008 (73 FR 67456-67463). The EPA promulgated
the Stage 1 and Stage 2 DBPRs to reduce drinking water exposure to
disinfection byproducts by setting standards for additional
disinfection byproducts, establishing maximum residual disinfectant
levels for chemical disinfectants, and tightening compliance monitoring
requirements. EPA has determined that the Stage 1 and Stage 2 DBPRs
were incorporated by reference into the Arizona
[[Page 47496]]
Administrative Code (AAC), Title 18, Chapter 4, in a manner that
Arizona's regulations are comparable to and no less stringent than the
federal requirements. EPA has also determined that the State's primacy
revision meets all of the regulatory requirements for approval, as set
forth in 40 CFR 142.12, including a side-by-side comparison of the
Federal requirements and the corresponding State authorities,
additional materials to support special primacy requirements of 40 CFR
142.16, and a statement by the Arizona Attorney General certifying that
Arizona's laws and regulations adopted by the State to carry out the
program revisions were duly adopted and are enforceable. Furthermore,
Arizona has an audit privilege law and has provided a legal opinion
that Arizona's audit privilege law does not impact the State's ability
to implement or enforce its PWSS program. Therefore, EPA is tentatively
approving the State's revisions as part of Arizona's PWSS Program.
Public Process. Any interested party may request a public hearing
on this determination. A request for a public hearing must be received
or postmarked before September 22, 2021, and addressed to the Regional
Administrator at the EPA Region 9 via the following email address:
<a href="/cdn-cgi/l/email-protection#a7f59ec3d08ad7d5c8c0d5c6cae7c2d7c689c0c8d1"><span class="__cf_email__" data-cfemail="cb99f2afbce6bbb9a4acb9aaa68baebbaae5aca4bd">[email protected]</span></a>. Please note, ``State Primacy Rule Determination''
in the subject line of the email. The Regional Administrator may deny
frivolous or insubstantial requests for a hearing. If a substantial
request for a public hearing is made before September 24, 2021, EPA
Region 9 will hold a public hearing. Any request for a public hearing
shall include the following information: 1. The name, address, and
telephone number of the individual, organization, or other entity
requesting a hearing; 2. A brief statement of the requesting person's
interest in the Regional Administrator's determination and a brief
statement of the information that the requesting person intends to
submit at such hearing; and 3. The signature of the individual making
the request, or, if the request is made on behalf of an organization or
other entity, the signature of a responsible official of the
organization or other entity.
If EPA Region 9 does not receive a timely and appropriate request
for a hearing and the Regional Administrator does not elect to hold a
hearing on her own motion, this determination shall become final and
effective on September 24, 2021, and no further public notice will be
issued.
Authority: Section 1413 of the Safe Drinking Water Act, as amended,
42 U.S.C. 300g-2 (1996), and 40 CFR part 142 of the National Primary
Drinking Water Regulations.
Dated: July 28, 2021.
Deborah Jordan,
Acting Regional Administrator, EPA Region 9.
