The Maricopa County Air Quality Department (MCAQD) complied with all statutory and county
policies throughout this rulemaking process. Per the Enhanced Regulatory Outreach Program
(EROP) Policy: “In addition to the required staff report, an executive summary of the report including
an overview of stakeholder input and staff responses will be provided to the Board of Supervisors at
least one week prior to any Board of Supervisors’ public hearing.”
Overview of the Report to the Board of Supervisors: The MCAQD is proposing to incorporate

amendments in this rulemaking implement federal requirements according to each federal program
identified or applicable source type subject to these regulations. The proposed action will include
incorporating 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

Background: Return to list of attachments

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, 2017, to July 1, 2018, 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.
Description of Proposed Amendments:
Proposed Significant Amendments Common to Rules 360, 370, 371 and Appendix G:
To amend the incorporation by reference date from “July 1, 2017” to “July 1, 2018.”
Proposed Significant Amendments to Rule 360 (New Source Performance Standards):
This proposed incorporation by reference is substantially identical to 40 CFR 60, Subparts XXX
and OOOOa. Updates to the federal NSPS regulations at 40 CFR 60 are proposed to be
incorporated by reference as of July 1, 2018, and no future editions or amendments.
Proposed Significant Amendments to Rule 370 (Federal Hazardous Air Pollutant
Program): This proposed incorporation by reference is substantially identical to 40 CFR 63
Subparts A, AA, BB, DD, MM, NNN, VVV and CCCC. Updates to the federal NESHAP
regulations at 40 CFR 63 are proposed to be incorporated by reference as of July 1, 2018, and no
future editions or amendments. There are no proposed revisions to 40 CFR Part 61 for this
rulemaking.
Proposed Significant Amendments to Rule 371 (Acid Rain): There are no proposed revisions
to 40 CFR Part 72, Part 74, Part 75 and Part 76 for this rulemaking.
Proposed Significant Amendments to Appendix G (Incorporated Materials):

This proposed incorporation by reference includes updates to specific sections in the CFR. The
proposed amendments to Appendix G are substantially identical to 40 CFR 50; 40 CFR 51 Subpart
M; 40 CFR 53; 40 CFR 58; 40 CFR 60 Appendices B and F; and 40 CFR 63, Appendix A.
The MCAQD is also proposing the following:
Rule 360:
- To add 40 CFR Part 60, Subpart XXX—Standards of Performance for Municipal Solid Waste
Landfills That Commenced Construction, Reconstruction, or Modification After July 17,
2014.
- To add 40 CFR Part 60, Subpart OOOOa—Standards of Performance for Crude Oil and
Natural Gas Facilities for Which Construction, Modification or Reconstruction Commenced
After September 18, 2015.
Appendix G: The proposed revisions to Appendix G are substantially identical to the applicable
code of federal regulations to which they apply.
- To add t-Butyl Acetate (also known as TBAC; CAS number 540-88-5) to the table of federally
listed non-precursor organic compounds, which have been determined to have negligible
photochemical reactivity as listed in 40 CFR 51.100(s).
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.
7. Demonstration of compliance with A.R.S. §§ 49-112 and 49-471.08:
The MCAQD is proposing to declare this as an expedited rule making 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 (New Source Performance Standards) is substantially identical to 40 CFR Part 60,
Subparts XXX and OOOOa.

Rule 370 (Federal Hazardous Air Pollutant Program) is substantially identical to 40 CFR 63,
Subparts A, AA, BB, DD, MM, NNN, VVV and CCCC.
Rule 371 (Acid Rain) is substantially identical to 42 CFR 72, 74, 75 and 76.
Appendix G is substantially identical to substantially identical to 40 CFR 50; 40 CFR 51 Subpart
M; 40 CFR 53; 40 CFR 58; 40 CFR 60 Appendices B and F; 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 was required to update the applicability dates in these rules. This rulemaking
proposes to incorporate subparts that were passed by the federal government and are required to
be implemented by 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 § 49-112.
8. Documents or studies referenced and/or reviewed for this rulemaking:
All studies relating to the subparts proposed to be incorporated by reference 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.

kept adequately wet by using amended water to control the release of
asbestos fibers. The use of amended water will not be required in the
case of an ordered demolition, as defined in 40 CFR 61.145(a)(3), where
the debris is suspected to contain or is known to contain ACM , however
ordered demolitions are subject to 40 CFR 61.145(c)(9). Specific
