1.2 Regulatory Background:
Congress established the basic structure of the Clean Air Act (“CAA”) in 1970. The CAA
requires the EPA to establish national ambient air quality standards (“NAAQS”) for common
and widespread pollutants based on the most current science available. For geographic areas
that were determined to be in nonattainment of the NAAQS, states are required to adopt
federally enforceable SIPs in order to achieve and maintain air quality and meet the federally
established air quality standards (the NAAQS).
In order to comply with the CAA, the MCAQD submitted the Maricopa County Air Quality
Regulations for facilities under the jurisdiction of the MCAQD to the ADEQ, the designated
EPA contact, for inclusion in the original SIP submittal made on January 28, 1972. Through
the years, the MCAQD has revised the Maricopa County Air Quality Regulations submitted
in the original SIP and has submitted such revised Maricopa County Air Quality Regulations
for inclusion in the SIP.
The original MCAQD rules were one- and two-digit rules. In the 1980’s, the MCAQD revised
some of the rules to address reasonably available control technology (“RACT”) and best
available control technology (“BACT”) in order to comply with the NAAQS. At the same
time, the MCAQD reformatted and renumbered all of the rules using a three-digit numbering
system. During this transition, some of the reformatted and renumbered rules were not
included as SIP revisions. Likewise, some of the two-digit rules were not rescinded (removed)
from the SIP. This resulted in the overlap or conflict of requirements between the two-digit
SIP-approved Maricopa County Air Pollution Control Regulations and the current three-digit
Maricopa County Air Pollution Control Regulations. This overlap or conflict complicates the
permitting process when the MCAQD is required to determine which rules, or parts of a rule,
are federally enforceable and which are locally enforceable. In April 2016, the EPA and the
MCAQD analyzed each of the two-digit SIP-approved Maricopa County Air Pollution
Control Regulations in order to update the SIP. The EPA analysis of each SIP-approved rule
specified how the Maricopa County Air Quality Regulation did or did not meet the current
SIP requirements under the CAA and provided their recommendation for updating the SIP
with current MCAQD Maricopa County Air Quality Regulations. The MCAQD also identified
some three-digit SIP-approved Maricopa County Air Pollution Control Regulations relating
to the two-digit SIP-approved Maricopa County Air Pollution Control Regulations that
preceded the current three-digit Maricopa County Air Pollution Control Regulations and
therefore need to be rescinded (removed).
Through this collaboration with the EPA, the MCAQD is formally submitting this request to
the EPA through the ADEQ, to rescind (remove) SIP-approved rules from the Arizona SIP.
The MCAQD is formally requesting the EPA to approve Maricopa County Air Pollution
Control Regulations as identified in Section 1.1 of this document into the Arizona SIP.
SECTION 2: COMPLETENESS CRITERIA
2.1 Administrative Materials:
2.1(a) A formal letter of submittal from the MCAQD Director or [his] designee,
requesting the EPA approval of the SIP revision.

See SIP submission cover letter from Philip A. McNeely, Director of the MCAQD,
included above.
2.1(b) Evidence that the MCAQD has adopted the SIP revision in the State code or
body of regulations; or issued the permit, order, consent agreement in final
form.
On September 6, 2017, the Maricopa County Board of Supervisors gave the MCAQD
approval to request the EPA to rescind (remove) SIP-approved rules and to request
the EPA to approve the Maricopa County Air Pollution Control Regulations as
identified in Section 1.1 of this document, into the Arizona SIP.
See Appendix 1 of this document.
2.1(c) Evidence that the MCAQD has the necessary legal authority under State law to
adopt and implement the SIP revision.
Arizona Revised Statutes §§ 49-112, 49-474, 49-471.09, and 49-479 authorize
MCAQD to submit rule revisions for approval in the SIP. See Appendix 2 of this
document.
2.1(d) A copy of the actual regulations, or documents submitted for approval and
incorporation by reference into the plan, including indication of the changes
made to the existing approved plan, where applicable.
Copies of the SIP-approved Maricopa County Air Pollution Control Regulations are
included in Appendix 3 and the current Maricopa County Air Pollution Control
Regulations are included in Appendix 4 of this document. For the purpose of this
document ONLY, strike-outs indicate the SIP-approved Maricopa County Air
Pollution Control Regulations (Appendix 3) that are requested to be rescinded
(removed) from the Arizona SIP. For the purpose of this document ONLY,
underlines indicate the current Maricopa County Air Pollution Control Regulations
(Appendix 4) that are requested to be approved by the EPA into the Arizona SIP. No
revisions were made to the current regulations in this request to the EPA to update
the Arizona SIP. A summary and justification of the requested action for each SIP-
approved rule is in Table 1 below. A detailed description of each SIP-approved
Maricopa County Air Pollution Control Regulation and the MCAQD requested action
follows the table.

SIP Rule 22: Operating Permits
SIP Rule 22 (Operating Permits), as adopted on August 12, 1971, was one of the
original rules submitted for inclusion in the SIP. On July 27, 1972, the EPA approved
Rule 22 into the Arizona SIP (37 FR 15080).
In 1988, the MCAQD revised the requirements for a permit to operate and
renumbered SIP Rule 22 to Rule 220 (Permits to Operate). Per the 1988 SIP
completeness checklist, Rule 220 is analogous to SIP-approved Rule 22. Rule 220 was
submitted on September 26, 1989, to the ADEQ who forwarded the SIP submittal to
the EPA on January 4, 1990. Rule 220 (Permits to Operate), was revised and adopted
by the Board on July 13, 1988. SIP Rule 22.B and E were superseded and removed
from the Arizona SIP by EPA approval of Rule 220 on January 6, 1992 (57 FR 354)
into the SIP.
Until 1993, Maricopa County required two permits for stationary sources: an
installation permit before beginning construction or modification and a separate
permit authorizing operation of the new source or modification. In 1993, Maricopa

County amended its air quality rules with the intention of meeting both the Title I
NSR requirements and the Title V operating permit requirements with a unitary
program that authorizes both construction and operation in a single permit. (Arizona
Administrative Register, 46 A.A.R. 4249, November 17, 2006). To include the
provisions found in SIP Rule 22 for all types of sources, the MCAQD also repealed
and revised Rule 210 (Title V Permit Provisions) and drafted the new Rule 230
(General Permits). The revisions to Rules 210, 220 and 230 clarified the requirements
for Title V, Non-Title V and General Permitted sources, thus making each rule more
stringent and enforceable than SIP Rule 22. Revisions to Rules 210, 220 and 230 as
adopted on February 3, 2016, updated the MCAQD’s major New Source Review
(“NSR”) rules to reflect current federal requirements and added new minor NSR
requirements.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 22 (Operating
Permits), as approved into the Arizona SIP on July 27, 1972 (37 FR 15080) and SIP
Rule 220 (Permits to Operate) as approved into the Arizona SIP on January 6, 1992
(57 FR 354), from the Arizona SIP. The MCAQD is requesting the EPA to approve
the Maricopa County Air Pollution Control Regulations, Regulation II-Permits and
Fees, Rule 210 (Title V Permit Provisions), Rule 220 (Non-Title V Permit Provisions)
and Rule 230 (General Permits) as revised and adopted February 3, 2016, into the
Arizona SIP. These rules were submitted to the EPA on May 19, 2016, as part of the
NSR SIP submittal.
SIP Rule 27: Performance Tests
SIP Rule 27 (Performance Tests), as adopted on June 23, 1980, was submitted for
inclusion in the SIP on June 23, 1980. The EPA approved Rule 27 into the SIP on
April 12, 1982 (47 FR 15579). SIP Rule 27 does not establish emission limits or control
strategies for pollutants as necessary for enforcement or achieve emissions reductions.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 27 as approved into the Arizona SIP on April 12, 1982 (47 FR

SIP Rule 28: Permit Fees
SIP Rule 28 (Permit Fees) establishes installation permit fees and annual operating
fees for various types of equipment and processes. Rule 28 was approved into the SIP
on June 18, 1982 (47 FR 26382). Rule 28 was again submitted on October 24, 1984,
to the EPA “…as an official revision to the Arizona State Implementation Plan.” The
program fee requirement is statutorily mandated by Arizona Revised Statutes (A.R.S.)
§§ 49-480(D)(1) and (D)(2). A.R.S. § 49-480(D)(1) requires the MCAQD to establish
a fee system for Title V sources that is consistent with and equivalent to that prescribed
under § 502 of the CAA. A.R.S. § 49-480(D)(2) requires a permit fee for Non- Title V
sources to be based on all reasonable direct and indirect costs required to administer
the permit, but not to exceed twenty-five thousand dollars. Furthermore, A.R.S. §
49- 480(D)(2) requires the establishment of an annual inspection fee, not to exceed
the average cost of services. Arizona law and the CAA both provide for increasing
permit fees based on the consumer price index. (As published at 16 A.A.R. 1270, July
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 15 of 249

The fees in SIP Rule 28 as adopted by the Board October 25, 1982, are outdated. SIP
Rule 28 does not establish emission limits or control strategies for pollutants or achieve
emissions reductions.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 28 as approved into the Arizona SIP on June 18, 1982 (47 FR

SIP Rule 32: Odors and Gaseous Emissions (A-H and J-K)
SIP Rule 32.A (Odors and Gaseous Emissions) as adopted August 12, 1971, and
approved into the Arizona SIP on July 27, 1972 (37 FR 15080) is a general prohibitory
rule against emitting gaseous or odorous emissions in such quantities as to cause air
pollution. Rule 32.A lacks specific emissions limits or other elements necessary for
enforcement and does not achieve any emissions reductions. Moreover, it is not
needed to fulfill any SIP requirement.

SIP Rule 32.B (Odors and Gaseous Emissions) as adopted August 12, 1971, and
approved into the Arizona SIP on July 27, 1972 (37 FR 15080), covers treatment or
processing of animal or vegetable matter and prohibits such operations unless all
effluents from such operations have been incinerated to destruction under certain
specified conditions and requires use of control devices as necessary to prevent air
pollution. Rule 32.B is a general nuisance-type regulation. It does not relate to the
implementation, maintenance, or enforcement of the NAAQS, therefore is not
required to be in the SIP.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 32.B as approved into the Arizona SIP on July 27, 1972 (37 FR

SIP Rule 32.C (Odors and Gaseous Emissions) as adopted August 12, 1971, and
approved into the Arizona SIP on July 27, 1972 (37 FR 15080), requires reasonable
measures and installation of control devices to reduce emissions from evaporation,
leakage or discharge from the processing, storage, use and transport of materials such
as solvents, paints, acids, fertilizers and manure. SIP Rule 32.C lacks specific work
practice or other elements necessary for enforcement, and as such, does not achieve
any emissions reductions. Moreover, it is not needed to fulfill any SIP requirement.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 32.C as approved into the Arizona SIP on July 27, 1972 (37 FR

SIP Rule 32.F (Odors and Gaseous Emissions) as adopted August 12, 1971, and
approved into the Arizona SIP on July 27, 1972 (37 FR 15080), establishes property-
line concentrations standards for sulfur dioxide and sulfuric acid due to emissions of
sulfur oxides or sulfuric acid at a facility. Per the EPA analysis, limiting the sulfur oxide
concentrations at a property line could “theoretically act to limit sulfur oxide
emissions…” making SIP Rule 32.F applicable to the NAAQS. In 2006, Rule 510 (Air
Quality Standards) was revised to clarify the sulfur oxide emissions and mirror the
sulfur dioxide NAAQS, thus and making Rule 510 more stringent than SIP Rule 32.F.
Rule 510 as revised and adopted on November 1, 2006, was approved into the Arizona
SIP on November 9, 2009 (74 FR 57612).
In 2010, the EPA revised the primary sulfur oxide standard by establishing a new one-
hour standard of 75 ppb and revoking the existing 24-hour standards (75 FR 35520,
June 22, 2010). The current sulfur oxide standard is more stringent than the sulfur
oxide standard listed in SIP Rule 32.F and SIP Rule 510.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 32.F as approved into the Arizona SIP on July 27, 1972 (37 FR

SIP Rule 32.G (Odors and Gaseous Emissions, Other Industries) as adopted October
1, 1975 and approved into the Arizona SIP on April 12, 1982 (47 FR 15579) prohibits
a person from emitting reduced sulfur in excess of ten percent (10%) of the sulfur
entering the process as feed. The Notice of Final Rulemaking (9 A.A.R. 3388, August
1, 2003) documented that no sulfuric acid plants were located within Maricopa County.
Currently there are no facilities located within Maricopa County that use sulfur
entering a process as feed.

SIP Rule 32.H (Odors and Gaseous Emissions, Fuel Burning Equipment for
Producing Electric Power) as adopted October 1, 1975 and approved into the Arizona
SIP on April 12, 1982 (47 FR 15579) applies to installations that are operated to
produce electrical power. These types of facilities emit sulfur dioxide as a by-product.
SIP Rule 32.H established sulfur dioxide emission limits for new oil burning sources,
existing oil burning sources, new coal burning sources and existing coal burning
sources.
Maricopa County Rule 322 (Power Plant Operations) applies to facilities that burn
fossil fuel. These types of facilities include the electric utility steam generating unit or
cogeneration steam generating unit used to generate electric power; an electric utility
stationary gas turbine; and the cooling tower(s) associated with the equipment. Rule
322 was approved into the Arizona SIP on October 14, 2009 (74 FR 52693). SIP Rule
322 establishes standards for particulate matter (“PM”) (Section 301); Sulfur in fuel
(Section 305); Nitrogen Oxides (“NOx”) (Section 306); and Carbon Monoxide (“CO”)
(Section 307). SIP Rule 322 specifies requirements for emission monitoring
equipment, operation and maintenance plans; and emission compliance
demonstration. The specific emission standards in SIP Rule 322 make the rule more
stringent than SIP Rule 32.H.
Rule 322, as revised and adopted on November 2, 2016, addressed the requirements
of the SIP for “moderate” nonattainment for the 2008 eight- hour ozone NAAQS.
The revisions to Rule 322 included RACT for NOx making Rule 322 more stringent
than SIP Rule 322.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 32.H as approved
into the Arizona SIP on April 12, 1982 (47 FR 15579) and SIP Rule 322 as approved
into the Arizona SIP on October 14, 2009 (74 FR 52693) from the Arizona SIP. The
MCAQD is requesting the EPA to approve the Maricopa County Air Pollution
Control Regulations, Regulation III-Control of Air Contaminants, Rule 322 (Power
Plant Operations) as revised and adopted November 2, 2016, into the Arizona SIP.
This rule was submitted to EPA on December 19, 2016, as part of the Ozone SIP.
SIP Rule 32.J (Odors and Gaseous Emissions, Operating Requirements for an
Asphalt Kettle) as adopted June 23, 1980, and approved into the Arizona SIP on April
12, 1982 (47 FR 15579) established operational requirements primarily to reduce the
potential for nuisance odors. SIP Rule 32.J relies on controlling the “…air contaminant
emissions by good modern practices…” No specific emission limits are in the rule
thus limiting the enforceability of the rule. The control measures such as keeping the
kettle lid closed, only delay the emissions until the asphalt material is applied to the
roof. Any actual emission reductions achieved by the use of “good modern practices”
would be mostly negated by the evaporative emissions when applying the asphalt
material to a roof. It does not relate to the implementation, maintenance, or
enforcement of the NAAQS, therefore not required to be in the SIP.

SIP Rule 32.K (Odors and Gaseous Emissions, Emissions of Carbon Monoxide) as
adopted on June 23, 1980 and approved into the Arizona SIP on April 12, 1982 (47
FR 15579), states “The discharge of carbon monoxide emissions from any process
source shall be effectively controlled by means of secondary combustion.” Maricopa
County is designated as an attainment area for the carbon monoxide NAAQS. Per the
EPA, SIP Rule 32.K may provide a theoretical protection of property-line exceedances
of the standard. SIP Rule 322 Power Plant Operations) and SIP Rule 323 (Fuel
Burning from Industrial/Commercial/Institutional (ICI) Sources), both as approved
into the Arizona SIP on October 14, 2009 (74 FR 52693) clarify the CO limits, thus
making SIP-approved Rule 322 and SIP-approved Rule 323 more stringent than SIP
Rule 32.K.
On November 2, 2016, the MCAQD revised Rule 323 to address the requirements of
the State Implementation Plan (SIP) for “moderate” nonattainment for the 2008 eight-
hour ozone NAAQS. The amendments in Rule 323 included RACT for NOx. These
rule revisions make Rule 322, as revised in 2016, and Rule 323, as revised in 2016,
more stringent than SIP Rule 322 and SIP Rule 323.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 32.K as approved
into the Arizona SIP on April 12, 1982 (47 FR 15579); SIP Rule 322 as approved into
the Arizona SIP on October 14, 2009 (74 FR 52693); and SIP Rule 323 as approved

SIP Rule 34.A (Volatile Organic Compound Definition) as adopted June 23, 1980,
was approved into the Arizona SIP May 5, 1982 (47 FR 19326). Paragraph A was the
definition of one term: volatile organic compound. This definition, by itself, does not
meet any of the requirements of the NAAQS.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the

SIP Rule 34.B (Degreasers, General Provisions), as adopted June 23, 1980, and
approved into the SIP May 5, 1982 (47 FR 19326), limits the use of a vapor phase
degreasing operation through the use of “good modern practices” and requires any
spray degreasing to be conducted in an enclosure. In 1984, the MCAQD revised Rule
34. Paragraph A was deleted and Paragraph B now became Paragraph A. In 1988, the
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 19 of 249

MCAQD revised and renumbered all of the rules. The requirements of Rule 34.A (as
revised in 1984) were incorporated into new Rule 331. Per the SIP completeness
checklist document for the 1990 SIP submittal to the EPA, Rule 331 was analogous
to SIP Rule 34.A. On January 4, 1990, Rule 331 (Solvent Cleaning) was submitted to
the EPA through the ADEQ for inclusion in the Arizona SIP. Rule 331 was again
revised and resubmitted to order to meet the RACT requirements for ozone for non-
attainment areas. On February 1, 1996, the EPA approved Rule 331, as adopted June
22, 1992, into the SIP (61 FR 3578). Additional rule revisions and submittals by the
MCAQD occurred between 1992 and today. Rule 331, as revised and adopted April
21, 2004, is the EPA approved rule in the Arizona SIP (69 FR 76417, December 21,
2004). Rule 331 was again revised and adopted on September 25, 2013.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 34.B as approved

SIP Rule 34. C (Metal Cleaning Operations) as adopted June 23, 1980, and approved
into the SIP May 5, 1982 (47 FR 19326), describes the operating requirements of cold
organic solvent cleaning equipment, open top vapor degreasing operations,
conveyorized degreasers and emission control equipment. In 1984, the MCAQD
revised Rule 34. Paragraph A was deleted. Paragraph B became Paragraph A.
Paragraph C became Paragraph B. In 1988, the MCAQD revised and renumbered all
of the rules. The requirements of Rule 34.B (as revised in 1984) were incorporated into
new Rule 331. Rule 331 limits the emissions of volatile organic compounds (VOCs)
from surface cleaning and degreasing operations. Per the SIP completeness checklist
document for the 1990 SIP submittal to the EPA, Rule 331 is analogous to Rule 34.B.
On January 4, 1990, Rule 331 (Solvent Cleaning) was submitted to the EPA through
the ADEQ for inclusion in the Arizona SIP. Rule 331 was again revised and
resubmitted to order to meet the RACT requirements for ozone for non-attainment
areas. On February 1, 1996, the EPA approved Rule 331, as adopted June 22, 1992,
into the SIP (61 FR 3578). Additional rule revisions and submittals by the MCAQD
occurred between 1992 and today. The April 21, 2004, as revised Rule 331 is the
currently EPA approved rule Arizona SIP (69 FR 76417, December 21, 2004). In
September 25, 2013, the MCAQD clarified the definition of VOC making Rule 331
more stringent than SIP Rule 34.C and SIP Rule 331.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 34.C as approved

SIP Rule 34.D.2 (Dry Cleaning) as adopted June 23, 1980, and approved into the SIP
May 5, 1982 (47 FR 19326), describes the operating requirements for dry cleaning
equipment using petroleum solvents. In 1984, the MCAQD revised Rule 34. Paragraph
A was deleted. Paragraph D now became Paragraph C. In 1988, the MCAQD revised
and renumbered all of the rules. The requirements of Rule 34.C (as revised in 1984)
were incorporated into new Rule 333. Rule 333 controls the VOC emissions from
petroleum solvent dry cleaning operations. Per the SIP completeness checklist
document for the 1990 SIP submittal to the EPA, Rule 333 is analogous to Rule 34.C.
Two rule revisions (June 2, 1992 and June 19, 1996) were made to Rule 333 (Petroleum
Solvent Dry Cleaning) in order to meet the RACT requirements for ozone for non-
attainment areas. Revisions to meet RACT included requirements for a solvent
recovery system; cleaning equipment not to be operated with any perceptible liquid or
vapor leaks; specific storage requirements; and recordkeeping provisions. On February
26, 1997, the MCAQD submitted to the EPA through the ADEQ, Rule 333 for
inclusion in the Arizona SIP. SIP Rule 333 was approved by the EPA into the Arizona
SIP February 9, 1998 (63 FR 6489).
In 2013, the MCAQD again revised Rule 333 to clarify the definition of a VOC. Rule
333 as revised in 2013, is more stringent than SIP Rule 34.D.2 and SIP Rule 333.
The MCAQD is requesting the EPA to rescind (remove) from the Arizona SIP, SIP
Rule 34.D.2 as approved into the SIP May 5, 1982 (47 FR 19326) and SIP Rule 333 as
approved into the Arizona SIP February 9, 1998 (63 FR 6489) from the Arizona SIP.

SIP Rule 34.E (Spray Paint and Other Surface Coating Operations) as approved into
the Arizona SIP May 5, 1982 (47 FR 19326)
SIP Rule 34.E.1 (Spray Paint and Other Surface Coating Operations) describes the
requirements for containing overspray from surface coating operations. SIP Rule
34.E.1 does not provide any method in which to determine if the enclosure can actually
capture 96% of the overspray making this rule unenforceable. No test methods are
included in this rule.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 34.E.1 as approved into the Arizona SIP May 5, 1982 (47 FR

19326).
SIP Rule 34.E.2 (Spray Paint and Other Surface Coating Operations) describes the
requirements for architectural coatings. In 1984, the MCAQD revised Rule 34.
Paragraph A was deleted. Paragraph E now became Paragraph D. In 1988, the
MCAQD revised and renumbered all of the rules. The requirements of Rule 34.D (as
revised in 1984) were incorporated into new Rule 335 (Architectural Coatings).
Rule 335 controls the VOC emissions from architectural coatings. Per the SIP
completeness checklist document for the 1990 SIP submittal to the EPA, Rule 335 is
analogous to Rule 34.D. Rule 335 as adopted on July 13, 1988 and approved into the
Arizona SIP on January 6, 1992 (57 FR 354), was revised on September 25, 2013. Rule
335 as revised in 2013, is more stringent than SIP Rule 34.E.2 and SIP Rule 335.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 34.E.2 (Spray Paint

(57 FR 354) from the Arizona SIP. The MCAQD is requesting the EPA to approve
the Maricopa County Air Pollution Control, Regulation III-Control of Air
Contaminants, Rule 335 (Architectural Coatings) as revised and adopted September
25, 2013 into the Arizona SIP.
SIP Rule 34.E.3 (Spray Paint and Other Surface Coating Operations) is a definition.
SIP Rule 34.E.3 lacks specific emissions limits or other elements necessary for
enforcement, and does not achieve any emissions reductions. Moreover, it is not
needed to fulfill any SIP requirement.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 34.E.3 (Spray Paint and Other Surface Coating Operations) as
approved into the Arizona SIP May 5, 1982 (47 FR 19326).
SIP Rule 34.E.4 (Spray Paint and Other Surface Coating Operations-Other Coating
Operations) specifies emission limits for any coating applied by “spraying, dipping,
flow coating, electrodeposition or by any other means on any coating line or
operation…”
In 1984, the MCAQD revised Rule 34. Paragraph A was deleted. Paragraph E now
became Paragraph D. In 1988, the MCAQD revised and renumbered all of the rules.
The requirements of Rule 34.D (as revised in 1984) were incorporated into new Rule
336 (Surface Coating Operations). Rule 336 was revised several times by the MCAQD
and submitted on August 4, 1999, to the EPA for inclusion into the Arizona SIP. On
September 20, 1999 (64 FR 50759), the EPA approved Rule 336 into the Arizona SIP.
Rule 336 was revised and adopted on November 2, 2016. These revisions incorporate
the CTG RACT recommendations issued by the EPA in 2006 through 2008. Rule 336
revisions include additional types of VOC coating limits, transfer efficiency for spray
equipment, and additional work practices to reduce VOC emissions. Rule 336 as
revised in 2016, is more stringent than SIP Rule 34.E.4 and SIP Rule 336.

The requirements of Rule 34.E (as revised in 1984) were incorporated into new Rule
330 (Volatile Organic Compounds). Rule 330 was revised several times by the
MCAQD with the most current revision occurring in 2013. The purpose of Rule 330
is “To limit emissions of volatile organic compounds into the atmosphere that may
result from the use of organic solvents or processes that emit volatile organic
compounds.” Rule 330 clarified definitions and established limits for operations
involving heat (Section 301 of Rule 330); non-complying solvents (Section 302 of Rule
330); and process lines (Section 303). The rule also requires that emission of VOC be
reduced (Section 304 of Rule 303) by incineration, adsorption and use of low VOC
containing materials. In 2013, the definition of VOC was clarified. These revisions
make the Rule 330, as revised in 2013, more stringent than SIP Rule 34.G.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 34.F as approved
into the Arizona SIP May 5, 1982 (47 FR 19326) from the Arizona SIP. The MCAQD

The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 34.L (Cutback Asphalt) as approved into the Arizona SIP May
5, 1982 (47 FR 19326).
SIP Rule 35: Incinerators
SIP Rule 35 (Incinerators) as adopted on August 12, 1971, and approved into the
Arizona SIP on July 27, 1972 (37 FR 15080) establishes equipment specifications,
timing restrictions, informational requirements, performance test requirements, and
opacity and particulate standards for the use of incinerators in Maricopa County.
In 1988, the MCAQD revised and renumbered all of the rules. The requirements of
SIP Rule 35 were included in new Rule 313. Rule 313 required control equipment and
minimum temperatures for incinerators, burn-off ovens and crematories. Alternative
operating condition and special operating conditions were added to Rule 313.
Emission and opacity standards were included along with operating requirements for
nighttime combustion operations. The requirements in Rule 313 were more stringent
than SIP Rule 35. Rule 313 as adopted on May 9, 2012, was approved into the Arizona
SIP on September 25, 2014 (79 FR 57445).
SIP Rule 313 does not include any provision for hospital/medical/infectious waste
incinerators (HMIWI). In April 2017, the MCAQD conducted a review of permits and
industries within the jurisdiction of the MCAQD. No hospital/medical/infectious
waste incinerators were found to be located within the MCAQD jurisdiction. A
negative declaration will be submitted to the EPA stating this fact. The MCAQD is

SIP Rule 41: Monitoring
SIP Rule 41.A (Monitoring) as adopted August 12, 1971, and approved into the
Arizona SIP on July 27, 1972 (37 FR 15080) requires the owner or operator of a
stationary source to provide, maintain and operate monitoring devices to determine
compliance if requested by the Control Officer. SIP Rule 41.A provides for legally
enforceable procedures requiring owners or operators of stationary sources to
maintain records, as required by a SIP, to determine whether such sources are in
compliance with applicable requirements. Rule 41.A mirrors the Arizona Revised
Statutes (A.R.S.) Section 36-780 which was approved in the SIP in 1982 (47 FR 26382,
June 18, 1982). The A.R.S. is at least as stringent as SIP Rule 41.A.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 41.A as approved
into the Arizona SIP on July 27, 1972 (37 FR 15080), from the Arizona SIP. The
MCAQD is requesting the EPA to retain Arizona Revised Statutes (A.R.S.) Section
36-780 as approved into the Arizona SIP June 18, 1982 (47 FR 26382).
SIP Rule 41.B (Monitoring) as adopted October 2, 1978, and approved into the
Arizona SIP on April 12, 1982 (47 FR 15579) requires owners or operators of fossil-
fuel-fired steam generators, fluid bed catalytic cracking unit catalyst regenerators,
sulfuric acid plant and nitric acid plants (Rule 41.B.3) to install, calibrate and maintain
all monitoring equipment (Rule 41.B.8.a) necessary for continuously monitoring
opacity, nitrogen oxides, sulfur dioxide, oxygen and carbon dioxide.
Maricopa County Rule 245 (Continuous Source Emission Monitoring), mirrors the
requirements in Rule 41.B. Maricopa County Air Quality Regulation, Appendix A
(Fossil Fuel-Fired Steam Generators), outlines the procedures used to convert gaseous
emission monitoring data from parts per million to g/million cal (lb/million BTU).
The EPA has recommended to the MCAQD that SIP Rule 41.B be replaced with Rule
245 and Appendix A.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 41.B as approved
into the Arizona SIP on April 12, 1982 (47 FR 15579), from the Arizona SIP. The
MCAQD is requesting the EPA to approve the Maricopa County Air Pollution
Control Regulations, Regulation II-Permits and Fees, Rule 245 (Continuous Source
Emission Monitoring), as adopted November 15, 1993, and Maricopa County Air
Pollution Control Regulation, Appendix A (Fossil Fuel-Fired Steam Generators) as
adopted July 13, 1988, into the Arizona SIP.
SIP Rule 42: Testing and Sampling
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 27 of 249

SIP Rule 42 (Testing and Sampling) as adopted August 12 1971 and as approved into
the Arizona SIP on July 27, 1972 (37 FR 15080) requires owners of operators of
stationary sources to provide reasonable and necessary test openings in the system or
stack in order to allow for samples to be obtained. If the existing test openings are
inadequate to perform the required testing, the Control Officer shall notify the owner
or operator of the requirement to provide the necessary facilities for adequate
sampling. The rule does not provide any emission limits or reduce emissions.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 42 as approved into the Arizona SIP on July 27, 1972 (37 FR
15080).
SIP Rule 74: Public Notification
SIP Rule 74 (Public Notification) as adopted June 23, 1980 and approved into the
Arizona SIP April 12, 1982 (47 FR 15579) provides for public notification, on a daily
basis, of the pollution standard index (PSI) for the concentration level for three
pollutants: total suspended particulate matter, carbon monoxide and ozone. The
purpose of the PSI was to send a “clear and consistent message to the public by
providing nationally uniform information on air quality…” (64 Fed. Reg. 42530,
August 4, 1999). The methods of notification include newspapers, radio and television.
Rule 100 mirrored SIP Rule 74 until Rule 100 was revised in 2006 to incorporate the
EPA revisions for daily reporting to the general public.
In 1999, the EPA revised the daily air quality reporting requirements to the public.
These new requirements included the use of specific colors for categories; the addition
of new categories and thresholds; and a name change of the PSI to the Air Quality
Index (“AQI”) (64 Fed. Reg. 42530, August 4, 1999). The MCAQD Rule 100, as
adopted on March 15, 2006, was revised to include the text revision from "Pollution
Standard Index (PSI)" to "Air Quality Index (AQI)". (12 A.A.R. 1182, April 14, 2006).
Rule 100 was approved into the Arizona SIP on November 5, 2012 (77 FR 66405).
SIP Rule 100 was more stringent than SIP Rule 74 because the AQI included the
additional reporting requirements; the use of specific colors for categories; and the
addition of new categories and thresholds. On February 3, 2016, the MCAQD revised
Rule 100 as part of the NSR revisions.
The MCAQD is requesting the EPA to rescind (remove) SIP Rule 74 as approved into
the Arizona SIP April 12, 1982 (47 FR 15579) and SIP Rule 100 as approved into the
Arizona SIP on November 5, 2012 (77 FR 66405) from the Arizona SIP. The
MCAQD is requesting the EPA to approve the Maricopa County Air Pollution
Control Regulations, Regulation I-General Provisions, Rule 100 (General Provisions
and Definitions) as revised and adopted February 3, 2016, into the Arizona SIP. This
rule was submitted to the EPA on May 19, 2016, as part of the NSR SIP submittal.
SIP Rule 81: Operation
SIP Rule 81 (Operation) as adopted August 12, 1971, and approved into the Arizona
SIP July 27, 1972 (37 FR 15080) states “Nothing in these Rules and Regulations shall
in any manner be construed as authorizing or permitting the creation or maintenance
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 28 of 249

of a nuisance. SIP Rule 81 does not relate to the SIPs’ purpose under the Clean Air
Act, Section 110(a) of implementing, maintaining and enforcing the NAAQS.
Therefore, Rule 81 does not need to be retained as part of the SIP.
The MCAQD is requesting the EPA to rescind (remove) without replacement in the
Arizona SIP, SIP Rule 81 as approved into the Arizona SIP July 27, 1972 (37 FR
15080).

REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 29 of 249

2.2(b) Identification of the locations of affected sources including the EPA
attainment/nonattainment designation of the locations and the status of the
attainment plan for the affected areas(s).
The rules listed in Section 2.1(b) of this document are potentially applicable to all areas
and sources under the MCAQD’s jurisdiction. The EPA attainment/nonattainment
designations for all or parts of Maricopa County are:
PM10 Classification: Serious (As of June 6, 2007)
Carbon Monoxide Classification: Attainment (As of April 2005)
Ozone Classification: Moderate (As of May 4, 2016)
PM2.5 Classification: Unclassified/Attainment (As
of March 2011)
2.2(c) Quantification of the changes in plan allowable emissions from the affected
sources; estimates of changes in current actual emissions from affected sources
or, where appropriate, quantification of changes in actual emissions from
affected sources through calculations of the differences between certain
baseline levels and allowable emissions anticipated as a result of the revision.
The rescission (removal) of the SIP rules from the Arizona SIP, as identified in Section
2.1(b) of this document, will not result in any changes to allowable or actual emissions
from existing sources.
The approval of the rules, as identified in Section 2.1(b) of this document, into the
Arizona SIP will not result in any changes to allowable or actual emissions from
existing sources.
2.2(d) The MCAQD’s demonstration that the national ambient air quality standards,
prevention of significant deterioration increments, reasonable further progress
demonstration, and visibility, as applicable, are protected if the plan is
approved and implemented.
The SIP rules as identified in Section 2.1(b) of this document, are being requested to
be rescinded (removed) because the rule(s):
1. Does (Do) not provide specific authority to the officers of the county to fulfill any
particular regulatory function, nor establish any type of emissions standard or
address any particular requirement for SIPs under the CAA;
2. Does (Do) not relate to the implementation, maintenance, or enforcement of the
NAAQS or achieve emissions reductions;
3. Lack specific emissions limits or other elements necessary for enforcement; or
4. Have been revised and adopted by the Board of Supervisors.
The rules as identified in Section 2.1(b) of this document are being requested to be
approved into the Arizona SIP because the rules:
1. Relate to the implementation, maintenance, or enforcement of the NAAQS or
achieve emissions reductions;
2. Establish specific emissions limits or other elements necessary for enforcement;
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 30 of 249

3. Provide specific authority to the officers of the county to fulfill a particular
regulatory function; and
4. Have been revised and adopted by the Board of Supervisors.
The rescission (removal) of SIP-approved Maricopa County Air Pollution Control
Regulations and the Maricopa County Air Pollution Control Regulations that are
requested to be approved by the EPA into the Arizona SIP will not affect the NAAQS,
prevention of significant deterioration increments, reasonable further progress
demonstration or visibility. Because of the inclusion of specific authorities for
regulatory functions, emission limits or other elements necessary for the enforcement
of the rules, the replacement of the current SIP-approved Maricopa County Air
Pollution Control Regulations with the current Maricopa County Air Pollution
Control Regulations actually increases the stringency and enforceability of the federal
regulations.
Refer to Table 1: Summary and Justification of the Requested Action in Section 2.1(d) of this
document.
2.2(e) Modeling information required to support the proposed revision, including
input data, output data, models used, justification of model selections, ambient
monitoring data used, meteorological data used, justification for use of offsite
data (where used), modes of models used, assumptions, and other information
relevant to the determination of adequacy of the modeling analysis.
Not applicable because no new emissions limitations or alterations to existing emission
limitations are being implemented.
2.2(f) Evidence, where necessary, that emission limitations are based on continuous
emission reduction technology.
Not applicable because no new emission limitation or alterations to existing emission
limitations are being implemented.
2.2(g) Evidence that the plan contains emission limitations, work practice standards
and recordkeeping/reporting requirements, where necessary, to ensure
emission levels.
The emission limitations, work practices and recordkeeping and reporting
requirements have already been addressed during each rulemaking previously
conducted by the MCAQD. Rule 100, Rule 210, Rule 220, Rule 230, Rule 245, Rule
313, Rule 322, Rule 323, Rule 330, Rule 331, Rule 333, Rule 335, Rule 336 and
Appendix A are currently in effect. Therefore no additional emission limitations, work
practice standards, recordkeeping or reporting is required to justify the rescission
(removal) of SIP Rule 22, SIP Rule 27, SIP Rule 28, SIP Rule 32 A-H and J-K, SIP
Rule 34 A-L, SIP Rule 35, SIP Rule 41.A and B, SIP Rule 42, SIP Rule 74, SIP Rule
81, SIP Rule 100, SIP Rule 220, SIP Rule 322, SIP Rule 323, SIP Rule 331, SIP Rule
333, SIP Rule 335, SIP Rule 336, SIP Rule 340 and SIP Rule 510.
2.2(h) Compliance/enforcement strategies, including how compliance will be

determined in practice.
The compliance and enforcement strategies have already been addressed during each
rulemaking previously conducted by the MCAQD. Rule 100, Rule 210, Rule 220, Rule
230, Rule 245, Rule 313, Rule 322, Rule 323, Rule 330, Rule 331, Rule 333, Rule 335,
Rule 336 and Appendix A are currently in effect. Therefore no additional compliance
or enforcement strategy is required for the rescission (removal) of SIP Rule 22, SIP
Rule 27, SIP Rule 28, SIP Rule 32 A-H and J-K, , SIP Rule 34 A-L, SIP Rule 35, SIP
Rule 41.A and B, SIP Rule 42, SIP Rule 74, SIP Rule 81, SIP Rule 100, SIP Rule 220,
SIP Rule 322, SIP Rule 323, SIP Rule 331, SIP Rule 333, SIP Rule 335, SIP Rule 336,
SIP Rule 340 and SIP Rule 510.
2.2(i) Special economic and technological justifications required by any applicable
EPA policies, or an explanation of why such justifications are not necessary.
The economic and technological justifications have already been addressed during
each rulemaking previously conducted by the MCAQD. Rule 100, Rule 210, Rule 220,
Rule 230, Rule 245, Rule 313, Rule 322, Rule 323, Rule 330, Rule 331, Rule 333, Rule
335, Rule 336 and Appendix A are currently in effect. Therefore no additional
economic or technological justification is required for the rescission (removal) of SIP
Rule 22, SIP Rule 27, SIP Rule 28, SIP Rule 32 A-H and J-K, SIP Rule 34 A-L, SIP
Rule 35, SIP Rule 41.A and B, SIP Rule 42, SIP Rule 74, SIP Rule 81, SIP Rule 100,
SIP Rule 220, SIP Rule 322, SIP Rule 323, SIP Rule 331, SIP Rule 333, SIP Rule 335,
SIP Rule 336, SIP Rule 340 and SIP Rule 510.
SECTION 3: CONCLUSION
This SIP revision is being submitted to the ADEQ to submit to the EPA for approval of the rescission
(removal) without replacement of SIP rules and for the EPA approval to include current Maricopa
County Air Pollution Control Regulations into the Arizona SIP.
The MCAQD requests the ADEQ to submit to the EPA the following SIP-approved rules for
approval of the rescission (removal) from the Arizona SIP, as these rules do not provide specific
authority to the officers of the county to fulfill any particular regulatory function; establish any type
of emissions standard or address any particular requirement for SIPs under the CAA; relate to the
implementation, maintenance, or enforcement of the NAAQS or achieve emissions reductions; lack
specific emissions limits or other elements necessary for enforcement; or are not the current versions

APPENDIX 2: RELEVANT ARIZONA REVISED STATUTES §§49-112, 49-471.09, 49-
474, and 49-479
A. When authorized by law, a county may adopt a rule, ordinance or other regulation that is
more stringent than or in addition to a provision of this title or rule adopted by the director or any
board or commission authorized to adopt rules pursuant to this title if all of the following conditions
are met:
1. The rule, ordinance or other regulation is necessary to address a peculiar local condition.
2. There is credible evidence that the rule, ordinance or other regulation is either:
(a) Necessary to prevent a significant threat to public health or the environment that results
from a peculiar local condition and is technically and economically feasible.
(b) Required under a federal statute or regulation, or authorized pursuant to an
intergovernmental agreement with the federal government to enforce federal statutes or regulations
if the county rule, ordinance or other regulation is equivalent to federal statutes or regulations.
3. Any fee or tax adopted under the rule, ordinance or other regulation will not exceed the
reasonable costs of the county to issue and administer that permit or plan approval program.
B. When authorized by law, a county may adopt rules, ordinances or other regulations in lieu of
a state program that are as stringent as a provision of this title or rule adopted by the director or any
board or commission authorized to adopt rules pursuant to this title if the county demonstrates that
the cost of obtaining permits or other approvals from the county will approximately equal or be less
than the fee or cost of obtaining similar permits or approvals under this title or any rule adopted
pursuant to this title. If the state has not adopted a fee or tax for similar permits or approvals, the
county may adopt a fee when authorized by law in the rule, ordinance or other regulation that does
not exceed the reasonable costs of the county to issue and administer that permit or plan approval
program.
C. If a county has adopted rules, ordinances or other regulations pursuant to subsection B of
this section and at any time cannot comply with subsection B of this section, the county shall give
notice of noncompliance to the director. The county shall file that notice with the secretary of state
for publication in the next issue of the Arizona administrative register at no cost to the county. If the
county does not comply with subsection B of this section within one year after publication of the
notice in the Arizona administrative register, the director shall provide written notice to and assert
regulatory jurisdiction over those persons and entities subject to the affected county rules,
ordinances or other regulations.
D. Except as provided in chapter 3, article 3 of this title, before adopting or enforcing any rule,
ordinance or other regulation pursuant to subsection A or B of this section, the county shall comply
with all of the following:
1. File with the secretary of state a written statement including a summary of the proposed rule,
ordinance or other regulation and a demonstration of the grounds and evidence of compliance with
subsection A or B of this section. The summary shall provide the name of the person with the
county to contact with questions or comments. The secretary of state shall publish the written
statement in the next issue of the Arizona administrative register at no cost to the county. The
county shall publish notice of the availability of the complete summary and the demonstration in
other newspapers as may be required by this title and shall make the text of any proposed
environmental rule, ordinance or other regulation available to the public at the same time it files the
written summary of the environmental rule, ordinance or other regulation with the secretary of state
as provided in this paragraph.
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 39 of 249

2. Provide at least thirty days' opportunity for comment by the public after publication of the
summary as prescribed by paragraph 1 of this subsection. The county shall accept written comments
on the proposed rule, ordinance or regulation and the written demonstration.
3. Respond in writing and make available to the public for a reasonable cost the county's
responses to the written comments submitted by the public pursuant to paragraph 2 of this
subsection.
4. Provide for a public hearing at the request of the authorized county officer or if there is
sufficient public interest. The county shall publish the notice of any public hearing at least twenty
days prior to the hearing. The county shall submit the notice of the public hearing to the secretary of
state for publication in the next issue of the Arizona administrative register at no cost to the county.
The county shall publish notice of any public hearing required pursuant to this paragraph in any
newspaper as prescribed by this title or county ordinance. The county shall select a time and location
for the public hearing that affords a reasonable opportunity for the public to participate.
E. A county is not required to comply with subsection D, paragraphs 2, 3 and 4 of this section
before it adopts or enforces a rule, ordinance or other regulation if the rule, ordinance or other
regulation only adopts by reference an existing state or federal rule or law that provides greater
regulatory flexibility for regulated parties and otherwise satisfies the requirements prescribed in
subsection B of this section.
F. Until June 30, 1995, a person may file with the clerk of the board of supervisors for that
county a petition challenging a county rule, ordinance or other regulation adopted before July 15,
1994 for compliance with the criteria set forth in subsection A or B of this section. The petition
shall contain the grounds for challenging the specific county rule, ordinance or other regulation.
Within one year after the petition is filed, the board of supervisors shall review the challenged rule,
ordinance or other regulation and make a written demonstration of compliance with the criteria set
forth in subsection A or B of this section and challenged in the petition. Any rules, ordinances or
other regulations that have been challenged and for which the board of supervisors has not made
the written demonstration within one year of the filing of the petition required by this section
become unenforceable as of that date. If a county has already made a written demonstration under
section 49-479, subsection C, for a rule, ordinance or regulation, the person filing the petition shall
state the specific grounds in the petition why that demonstration does not meet the requirements of
this section.
G. A rule, ordinance or other regulation adopted pursuant to subsection A of this section may
not be invalidated subsequent to its adoption on the grounds that the economic feasibility analysis is
insufficient or inaccurate if a county makes a good faith effort to comply with the economic
feasibility requirement of subsection A, paragraph 2, subdivision (a), of this section and has
explained in the written statement, made public pursuant to subsection D of this section, the
methodology used to satisfy the economic feasibility requirement.
H. This section shall not apply to any rule, ordinance or other regulation adopted by a county
pursuant to:
1. Title 36 for which the state has similar statutory or rule making authority in this title.
2. Section 49-391.
3. Chapter 3, article 8 of this title.
4. Chapter 4, article 3 of this title and section 49-765.
5. Nonsubstantive rules relating to the application process which have a de minimis economic
effect on regulated parties.

concise explanatory statement and response to comments.
49-474. County control boards
The board of supervisors of each county may authorize the board of health or health department of
their respective counties in cooperation with the department of environmental quality to:
1. 1. Study the problem of air pollution in the county.
2. 2. Study possible effects on adjoining counties.
3. 3. Cooperate with chambers of commerce, industry, agriculture, public officials and all
other interested persons or organizations.
4. 4. Hold public hearings if in their discretion such action is necessary.
5. 5. The board of supervisors by resolution may establish an air pollution control district.
49-479. Rules; hearing
A. The board of supervisors shall adopt such rules as it determines are necessary and feasible to
control the release into the atmosphere of air contaminants originating within the territorial limits of
the county or multi-county air quality control region in order to control air pollution, which rules,
except as provided in subsection C shall contain standards at least equal to or more restrictive than
those adopted by the director. In fixing such standards, the board or region shall give consideration
but shall not be limited to:
1. The latest scientific knowledge useful in indicating the kind and extent of all identifiable
effects on health and welfare which may be expected from the presence of an air pollution agent, or
combination of agents in the ambient air, in varying quantities.
2. Atmosphere conditions and the types of air pollution agent or agents which, when present in
the atmosphere, may interact with another agent or agents to produce an adverse effect on public
health and welfare.
3. Securing, to the greatest degree practicable, the enjoyment of the natural attractions of the
state and the comfort and convenience of the inhabitants.
B. No rule may be enacted or amended except after the board of supervisors first holds a
public hearing after twenty days' notice of such hearing. The proposed rule, or any proposed
amendment of a rule, shall be made available to the public at the time of notice of such hearing.

SIP Rule 27: Performance Tests
A. Within sixty (60) days after a source or facility subject to the installation and operating
permit requirements of these rules and regulations has achieved the capability to operate at
its maximum production rate on a sustained basis but no later than 180 days after initial
start-up of such source or facility and at such other times as may be required by the Control
Officer, the owner or operator of such source or facility shall conduct performance test(s)
and furnish the Control Officer a written report of the results of the test(s).
B. Performance tests shall be conducted and data reduced in accordance with the test method
and procedures contained in the Arizona Testing Manual unless the Control Officer:
1. Specifies or approves, in specific cases, the use of a reference method with minor
changes in methodology.
2. Approves the use of an equivalent method.
3. Approves the use of an alternative method the results of which he has determined to be
adequate for indicating whether a specific source is in compliance, or
4. Waives the requirement for performance tests because the owner or operator of a source
has demonstrated by the other means to the Control Officer’s satisfaction that the
source or facility is in compliance with the standard.
5. Nothing in this section shall be construed to abrogate the Control Officer’s authority to
require testing.
C. Performance tests shall be conducted under such conditions as the Control Officer shall
specify to the plant operator based on representative performance of the source or facility.
The owner or operator shall make available to the Control Officer such records as may be
necessary to determine the conditions of the performance tests. Operations during periods
of start-up, shutdown, and malfunction shall not constitute representative conditions of
performance tests unless otherwise specified in the applicable standard.
D. The owner or operator of a permitted source shall provide the Control Officer two (2)
weeks prior notice of the performance test to afford Control Officer the opportunity to have
an observer present.
E. The owner or operator of a permitted source shall provide, or cause to be provided
performance testing facilities as follows:
1. Sampling ports adequate for test methods applicable to such facility.
2. Safe sampling platform(s).

F. Each performance test shall consist of three (3) separate runs using the applicable test
method. Each run shall be conducted for the time and under the conditions specified in the
applicable standard. For the purpose of determining compliance with an applicable standard,
the arithmetic mean of results of the three (3) runs shall apply. In the event that a sample is
accidentally lost or conditions occur in which one (1) of the three (3) runs must be
discontinued because of forced shutdown, failure of an irreplaceable portion of the sample
train, extreme meteorological conditions, or other circumstances beyond the owner or
operator’s control, compliance my, upon the Control Officer’s approval, be determined
using the arithmetic mean of the results of the two (2) other runs.
G. Except as provided in subsection H. compliance with the emission limits established in this
regulation or as prescribed in permits issued pursuant to this regulation shall be determined
only by the performance tests specified in this rule.
H. In addition to performance tests specified in this rule, compliance with specific emission
limits may be determined by:
1. Opacity tests; and
2. Emission limit compliance tests specifically designated as such in the regulation
establishing the emission limit to be complied with.
I. Nothing in this section shall be so construed as to prevent the utilization of measurements
from emissions monitoring devices or techniques not designated as performance tests as
evidence of compliance with applicable good maintenance and operating requirements.

regulated by this Rule 336. Records shall be retained for 5 years and shall be made available
to the Control Officer upon request.
501.1 Current Lists:
a. Maintain a current list of coatings, adhesives, reducers, thinners, gun-cleaning
materials, additives, and any other VOC-containing materials regulated by this
rule; give the VOC content of material for each as received (before thinning). A
complete, neat assemblage of this data meets the requirements for a list. Express
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 174 of 249

VOC content in 1 of 3 forms: pounds VOC per gallon, grams VOC per liter, or
the percent VOC by weight along with the specific gravity or density,(2 numbers
are required).
b. Less Stringent Recordkeeping For Consistently Low Users: An operator of a
facility that always uses less than 2 gallons per day total of thinner and coating
(listed in Table 1), meets the listing and recording requirements of subsections
501.1a, 501.1c, and 501.2 if:
(1) All purchase receipts/invoices of VOC-containing material that is regulated
by this rule for the most recent 12 months are kept together; and
(2) Current data sheets show the VOC content of material for every VOC-
containing substance currently used that is regulated by this rule.
c. Facilities That Are Not Small Surface-Coating Sources: Facilities that are not
small surface-coating sources shall do the following:
(1) Coatings: For all coatings (except those recorded under the subsection
305.4c low usage allowance), make the following listings for coatings and
adhesives that have VOC limits in Table 1:
(a) VOC Before Reducing: The VOC content of each coating as received,
minus exempt compounds. (This figure is sometimes called the “EPA
Method 24” VOC content on manufacturer’s data sheets). If the coating
is a multi-part coating, list the VOC content which the manufacturer
states the coating will have once you have mixed all the necessary parts
together in the proportions specified by the manufacturer.
(b) List Maximum VOC Content Of Coating As Applied: For each coating
that you thin/reduce or add any additive to, record in a permanent log
either of the following:
(i) The maximum number of fluid ounces thinner/reducer that you ever
add to a gallon of unreduced coating (or maximum g/liter), and the
maximum fluid ounces of every other additive you mix into a gallon
of the coating; or
(ii) The VOC content of the coating, after adding the maximum amount
of thinner/reducer and other additives that you would ever add, as
determined by the formula in subsection 255.1.
(2) Applicator Cleanup Solvent: Have a hardcopy of the VOC vapor pressure
(VP) at 20˚C (68˚F) of solvent(s) used to clean spray guns, hoses, reservoirs,
and any other coating application equipment. Any one of the following ways
of providing the VP data is sufficient:
(a) A current manufacturer’s technical data sheet;
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 175 of 249

(b) A current manufacturer’s safety data sheet (MSDS);
(c) Actual test results; or
(d) A letter signed by an official or lab manager of the supplying facility.
501.2 Frequency Of Updating Usage Records: Update your records, showing the type and
amount used of each VOC-containing coating or adhesive which is regulated by
name or type in Table 1, and update each VOC-containing material, related to
surface coating, that is not addressed by Table 1. This includes, but is not limited to,
thinners, surfacers, and diluents. Maintain records according to the following
schedule:
a. Small Surface-Coating Sources: Small surface-coating sources shall update each
month’s records of coating use by the end of the following month.
b. All Other Sources: For a source that does not meet the definition of small
surface-coating source:
(1) Monthly: Monthly update records of each coating used that complies with
the VOC limits in Table 1. Complete a month’s update by the end of the
following month.
(2) Daily: Daily update the usage of each coating that exceeds its limits in Table
1, including coating exempted by subsection 305.4c.
501.3 Grouping By VOC Content: For purposes of recording usage, coatings and
adhesives that are in the same category in Table 1, and have similar VOC content,
may be recorded under a name that includes the category name. The highest VOC
content among the members of that grouping shall be assigned to that grouping,
rounded to the nearest 10th of a pound. To identify what products belong within
each group, after each group name and the group’s VOC content of material must
appear the name of each product in the group and its VOC content of material. For
example: For flexible plastic parts, you use 20 gallons of primer that has 3.04 lb
VOC/gal., 30 gallons of primer having 3.14 lb VOC/gal., and 40 gallons of primer
having 2.89 lb VOC/gal. You may record usage as 90 gallons of flexible plastic
primer containing 3.1 lb VOC/gal. If grams VOC per liter is used to record VOC
content, round off to the nearest whole number of grams.
502 ECS RECORDING REQUIREMENTS:
502.1 On each day an ECS is used at a facility pursuant to this rule, an owner or operator
of the facility shall:
a. Record the amount and VOC content of coating, the amount of
catalyst/hardener, and the amounts of solvent, reducer, and diluent used that
were subject to ECS control pursuant to this Rule 336; and
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 176 of 249

b. Make a permanent record of the operating parameters of the key systems as
required by the O&M Plan; and

the action’s completion, for each day or period in which the O&M Plan requires
that maintenance be done.
502.2. An explanation shall be entered for scheduled maintenance that is not performed
during the period designated for it in the O&M Plan.
503 COMPLIANCE DETERMINATION AND TEST METHODS: When more than one
test method is permitted for a determination, an exceedance of the limits established in the
rule determined by any of the applicable test methods constitutes a violation of this rule.
503.1 Compliance Determination: The following means shall be used to determine
compliance with this rule:
a. Measurement of VOC content of materials subject to Section 301 or Section 302
of this rule shall be conducted and reported using one of the following means:
(1) VOC content of coatings, solvents, and other substances having less than 5%
solids will be determined by the test method in subsection 503.2f
(BAAQMD Method 31 [April 15, 1992]) or 503.2g (SCAQMD Method 313-
91 [April 1997]).
(2) The VOC content of coatings or other materials having 5% or more solids
will be determined by the test method in subsection 503.2c (EPA Method
24), 503.2f (BAAQMD Method 31 [April 15, 1992]) or 503.2g (SCAQMD

implemented by a source due to physical plant limitations or extreme economic reasons.
Alternative monitoring procedures shall be specified by the Control Officer on a case by
case basis and shall include as a minimum annual manual stack tests for the pollutants
identified for each type of source in this rule. Examples of such special cases include, but
are not limited to, the following:
307.1 Alternative monitoring requirements may be prescribed when installation of a
continuous emission monitoring system or monitoring device specified by this rule
would not provide accurate determinations of emissions (e.g. condensed,
uncombined water vapor may prevent an accurate determination of opacity using
commercially available continuous emission monitoring systems).
307.2 Alternative monitoring requirements may be prescribed when the affected source is
infrequently operated (e.g. some affected sources may operate less than one month
per year).
SECTION 500 MONITORING AND RECORDS
501 DATA REDUCTION: Owners or operators of affected sources shall use the procedures
described in Appendix A for converting monitoring data to units of the standard where
necessary.
502 MONITORING DATA REQUIRED: Monitoring information shall be provided in writing
to the Control Officer as directed.
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 197 of 249

503 MONITORING EQUIPMENT INSPECTIONS: Air pollutant monitoring devices shall
be available for inspection by the Control Officer during all reasonable times (ARS §49-487).
504 TRANSMISSOMETER RESULTS: The results of continuous transmissometer monitoring
which indicate opacity was not in excess of the standard at the time of an alleged violation
from visual observations are probative but not conclusive evidence of the actual opacity of
an emission. The owner or operator of a source shall meet the burden of providing proof
that the transmissometer used meets performance specification 1 in the Arizona Testing
Manual for Air Pollutant Emissions, and that the instrument has been properly maintained
and calibrated, and the resulting data have not been tampered with in any way.

pollutant concentration and oxygen concentration shall each be on a consistent basis (wet or
dry).
a. When measurements are on a wet basis, except where wet scrubbers are employed or
where moisture is otherwise added to stack gases, the following conversion
procedure shall be used:
b. When measurements are on a wet basis and the water vapor content of the stack gas
is determined at least once every fifteen minutes the following conversion procedure
shall be used:
Note: This equation is approved in principle. Approval for actual practice is
contingent upon demonstrating the ability to accurately determine BWS such that
any absolute error in BWS will not cause an error of more than +/ 1.5 percent in the
term:
c. When measurements are on a dry basis, the following conversion procedure shall be
used:
(2) Measurement of Carbon Dioxide in Flue Gas: When the owner or operator elects to
measure carbon dioxide in the flue gases, the measurement of the pollutant concentration
and the carbon dioxide concentration shall each be on a consistent basis (wet or dry) and the
following conversion procedure used:
REVISIONS TO ARIZONA’S STATE IMPLEMENTATION PLAN (SIP) (September 2017) Page 241 of 249

The values used in the above equations are derived as follows:
EQ = Pollutant emission, g/million cal (lb/million BTU).
C = Pollutant concentration, g/dscm (lb/dsdf), determined by multiplying the
average concentration (ppm) for each hourly period by 4.16 x 10-5 M
g/dscm per ppm (2.64 x 10-9 M lb/dscf per ppm) where M = pollutant
molecular weight, g/g mole (lb/lb mole) or M = 64 for sulfur dioxide and 46
for oxides of nitrogen.
%O2, %CO2 = Oxygen or carbon dioxide volume (expressed as percent) determined with
equipment specified under Section 303 of Rule 245.
F,Fc = A factor representing a ratio of the volume of dry flue gases generated to the
calorific value of the fuel combusted (F), a factor representing a ratio of the
volume of carbon dioxide generated to the calorific value of the fuel
combusted (Fc), respectively. Values of F and Fc are given in § 60.45 (f) of
Part 60, Chapter 1, Title 40, Code of Federal Regulations.
Cws = Pollutant concentrations at stack conditions, g/wscm (lb/wscf), determined
by multiplying the average concentration (ppm) for each one hour period by
4.15 x 10-5 M g/wscm per ppm (2.59 x 10-9 M = lb/wscf per ppm) where M
= pollutant molecular weight, g/g mole (lb/lb mole) or M = 64 for sulfur
dioxide and 46 for nitrogen oxides.
%O2ws = Oxygen volume (expressed as percent wet basis) determined with
equipment specified under Section 303 of Rule 245.
Fw = A factor representing a ratio of the volume of wet flue gases generated to the
caloric value of the fuel combusted. Values of Fw are given in Federal
Register, Vol. 41, October 12, 1976, p. 44838, a.4.
Bwa = Proportion by volume of water vapor in the ambient air. Approval may be
given for determination of Bwa by on site instrumental measurement
provided that the absolute accuracy of the measurement technique can be
demonstrated to be within +/ 0.7 percent water vapor. Estimation methods
for Bwa are given in Federal Register, Vol. 41, October 12, 1976, p. 44838,
a.5.
Bws = Proportion by volume of water vapor in the stack gas.
SULFURIC ACID PLANTS: For sulfuric acid plants, the owner or operator shall:
(1) Establish a conversion factor three times daily according to the procedures of § 60.84 (b) of
Chapter 1, Title 40, Code of Federal Regulations dated 10/6/75;
(2) Multiply the conversion factor by the average sulfur dioxide concentration in the flue gases
to obtain average sulfur dioxide emission in Kg/metric ton (lb/short ton); and
(3) Report the average sulfur dioxide emission for each averaging period in excess of the
applicable emission standard in the quarterly summary.

NITRIC ACID PLANTS: For nitric acid plants, the owner or operator shall:
(1) Establish a conversion factor according to the procedures of §60.73(b) of Chapter 1, Title
40, Code of Federal Regulations;
(2) Multiply the conversion factor by the average nitrogen oxides concentration in the flue gases
to obtain the nitrogen oxides emissions in the units of the applicable standard;
(3) Report the average nitrogen oxides emission for each averaging period in excess of
applicable emission standard in the quarterly summary.
ALTERNATE DATA REPORTING OR REDUCTION PROCEDURES: The Control Officer
may allow data reporting or reduction procedures varying from those set forth in Rule 245 if the
owner or operator of a source shows to the satisfaction of the Control Officer that his procedures
are equally effective. Such procedures may include, but are not limited to the following:
(1) Alternative procedures for computing emission averages that do not require integration of
data (e.g., some facilities may demonstrate that the variability of their emissions is sufficiently
small to allow accurate reduction of data based upon computing averages from equally
spaced data points over the averaging period).
(2) Alternative methods of converting pollutant concentration measurements to the units of the
emission standards.
