6. Explanation of the rule, including the department’s reasons for initiating the rulemaking:
Background:
The Maricopa County Air Quality Department (“MCAQD”) is proposing to incorporate by reference various
federal regulations and documents promulgated by the U.S. Environmental Protection Agency (“EPA”) and
published in the Federal Register. The proposed amendments in this “Draft Notice of Final Rulemaking”
implement federal requirements according to each federal program identified or applicable source type subject
to these regulations. The proposed action will incorporate by reference actions relating to New Source
Performance Standards (“NSPS”), National Emission Standards for Hazardous Air Pollutants (“NESHAP”),
Acid Rain and other parts of Title 40 of the Code of Federal Regulations (“CFR”). The proposed amendments
implement federal requirements according to each federal program identified or applicable source type subject
to these regulations. The proposed action will include amending the incorporation by reference date from July 1,
2016, to July 1, 2017, in each of the rules to remain current with federal regulations. The adoption of the
proposed amendments to Maricopa County Air Pollution Control Regulations Rules 360, 370, 371 and
Appendix G is necessary prior to requesting the EPA’s delegation of authority to the MCAQD for the
implementation and enforcement of the federal regulations and documents.
In addition, the proposed amendments will correct typographical or other clerical errors; make minor
grammatical changes to improve readability or clarity; modify the format, numbering, order, capitalization,
punctuation, or syntax of certain text to increase standardization within and among rules; or make various other
minor changes of a purely editorial nature. As these amendments do not alter the sense, meaning, or effect of
the rule, they are not described in detail here, but can be readily discerned in the “strikeout and underline”
version of the rule contained in Item #17 of this notice.
Issues Raised and Discussed During This Rulemaking Process:
The MCAQD is proposing to delete specific federal standards from Rule 360 and Rule 370, because the
MCAQD does not have authority from the State of Arizona to regulate these sources. Per the Arizona Revised
Statutes (“A.R.S.”) § 49-402, the State of Arizona “shall have original jurisdiction over such sources, permits
and violations that pertain to…” metal ore smelting, petroleum refineries, coal fired electrical generating
stations and Portland Cement plants. Previous MCAQD rulemakings included the incorporation of federal
standards of performance into Rule 360 and Rule 370 for the listed sources; however, the MCAQD has no
jurisdiction per A.R.S. § 49-402. With this rulemaking, the MCAQD is proposing to delete the applicable
federal standards from Rule 360 and Rule 370 to come into compliance with the A.R.S. § 49-402 and to request
the EPA rescind (remove) delegated authority to the MCAQD for these subparts. The specific subparts
proposed to be deleted from Rule 360 and Rule 370 are listed in the “Description of Proposed Amendments”
below.

to have negligible photochemical reactivity as listed in 40 CFR 51.100(s)
7. Demonstration of compliance with A.R.S. §§ 49-112 and 49-471.08:
The MCAQD is proposing to declare this as an expedited rulemaking action as described in A.R.S. § 49-
471.08(A).
A.R.S. § 49-471.08(A)(1):
Demonstration that the rule or ordinance making is substantially identical to the sense, meaning and effect of
the federal or state rule or law from which it is derived.
Rule 360 is substantially identical to 40 CFR 60, Subparts A, Da, AAA, IIII, JJJJ, KKKK and OOOO.
Rule 370 (Federal Hazardous Air Pollutant Program) is substantially identical to 40 CFR 61, Subpart A; and 40
CFR 63 Subparts A, GG, XXX, UUUUU, and JJJJJJ.
Rule 371 (Acid Rain) is substantially identical to 42 CFR 72, 74, 75 and 76.
Appendix G (Incorporated Materials) is substantially identical to 40 CFR 50; 40 CFR 51 with Subparts S, M, P
and W; 40 CFR 52; 40 CFR 53; 40 CFR 58; 40 CFR 60 Appendices A, B and F; 40 CFR 61, Appendix B; and
40 CFR 63, Appendix A.
A.R.S. § 49-471.08(A)(2):
Written finding by the Control Officer setting forth the reasons why the rule or ordinance making is necessary
and does not alter the sense, meaning or effect of the federal or state rule or law from which it is derived.
This rulemaking is required to update the applicability dates in these rules. The rulemaking incorporates
subparts that have been promulgated by the federal government and which are required to be implemented by
7

the MCAQD. Rules 360, 370, 371, and Appendix G do not alter the sense, meaning or effect of the state rules
and federal regulations from which they are derived, as they incorporate language that is essentially the same as
the state's applicable rules and the federal code of regulations.
A.R.S. § 49-471.08(A)(3):
Demonstration that fees established in the rule or ordinance do not exceed limits specified in A.R.S. § 49-112.
Rules 360, 370, 371, and Appendix G do not establish fees. Any costs associated with these rules will come
from permit application fees for sources obtaining a permit revision to reflect new emission limits, due to
applicability of a new standard. Therefore, fees associated with these rules will be exactly the same as fees
associated with similar permits and would not exceed any limits specified in A.R.S. § 49-112.
8. Documents or studies referenced and/or reviewed for this rulemaking:
All studies relating to the incorporated subparts were conducted during the federal rulemaking process.
9. Showing of good cause why the rule is necessary to promote a statewide interest if the rule will diminish a
previous grant of authority of a political subdivision:
Not applicable
10. Summary of the economic, small business, and consumer impact:
The MCAQD is proposing to incorporate by reference the following federal regulations and documents
promulgated by the EPA and published in the Federal Register: New Source Performance Standards (NSPS),
National Emission Standards for Hazardous Air Pollutants (NESHAP), Acid Rain and other parts of Title 40
Code of Federal Regulations. These amendments should not have an economic impact on businesses in
Maricopa County and should not impose additional costs on the regulated community, small businesses,
political subdivisions, and members of the public beyond that already incurred by reason of federal or state rule
or law. The costs of compliance with these rules have already occurred and were considered when the federal
and state rule or law was proposed and adopted.

accuracy of the economic, small business, and consumer impact:
