Agenda Item: 
(Pending) 
Supervisor Districts: 
All Districts 
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: 
Rule 370 was adopted to establish performance standards for federally listed hazardous air pollutants. 
Most of the performance standards in Rule 370 are National Emission Standards for Hazardous Air 
Pollutants (NESHAP) which are promulgated by the U.S. Environmental Protection Agency (EPA) 
and are incorporated by reference into Rule 370. Section 301.9 of Rule 370 incorporates the asbestos 
NESHAP by reference and includes additional requirements for demolition and renovation projects 
in Maricopa County. 
The MCAQD is proposing to revise the local asbestos provisions in Section 301.9 of Rule 370 to 
clarify the requirements for demolition and renovation projects in Maricopa County and to remove 
requirements that are not protective of public health. Additional revisions are also being proposed 
under Sections 100 and 200 of the rule. With these revisions, Maricopa County will improve and 
enhance the rule as it pertains to the regulation of asbestos. 
Overview of Stakeholder Input and Staff Responses: 
During the rulemaking process, the MCAQD received written comments from three (3) 
stakeholders. One (1) stakeholder expressed support for the proposed revisions and two (2) 
stakeholders expressed neither support nor opposition to the proposed revisions. The MCAQD 
evaluated the comments and drafted responses. The stakeholder comments and the MCAQD 
responses to the comments are included in Section 9 of the attached Draft Notice of Final 
Rulemaking.

Request: 
Approve proposed revisions to Rule 370 (Federal Hazardous Air 
Pollutant Program). 
Rule 370 was adopted to establish performance standards for 
federally listed hazardous air pollutants. Most of the performance 
standards in Rule 370 are National Emission Standards for 
Hazardous Air Pollutants (NESHAP) which are promulgated by 
the U.S. Environmental Protection Agency (EPA) and are 
incorporated by reference into Rule 370. Section 301.9 of Rule 
370 incorporates the asbestos NESHAP by reference and 
includes additional requirements for demolition and renovation 
projects in Maricopa County. 
The Maricopa County Air Quality Department (MCAQD) is 
proposing to revise the local asbestos provisions in Section 301.9 
of Rule 370 to clarify the requirements for demolition and 
renovation projects in Maricopa County and to remove 
requirements that are not protective of public health. Additional 
revisions are also being proposed under Sections 100 and 200 of 
the rule. With these revisions, Maricopa County will improve and 
enhance the rule as it pertains to the regulation of asbestos. 
The proposed revisions to Rule 370 include the following: 
•
Add Section 104 (Exemptions) to exempt demolition and 
renovation projects from the requirements of Section 301.9 
which take place on a single owner-occupied solely residential 
parcel which contains 4 or fewer detached dwelling units.
•
Add the following definitions: AHERA Contractor/Supervisor,
AHERA Building Inspector, AHERA Worker, and Dwelling
Unit.
•
Remove the following definitions: Existing Source, Federally
Listed Hazardous Air Pollutant, Hazardous Air Pollutant, Major

Source, Modification, NESHAP, New Source and Stationary 
Source. 
•
Revise the definition of Government-Issued Photo Identification
Card to delete address from the list of information that needs to
be provided on a government-issued photo ID.
•
Clarify the inspection, sampling, and reporting requirements for
asbestos.
•
Delineate allowable laboratory test methods that can be used to
determine the presence of asbestos in sampled material.
•
Remove the requirement to thoroughly inspect the facility within
12 months of commencement of renovation or demolition
activity. A thorough inspection of a facility is still required before
the commencement of renovation or demolition activity, but it
does not necessarily need to occur within 12 months of
commencement of renovation or demolition activity.
•
Add an exemption to the inspection requirement if the owner or
operator assumes the materials present are regulated asbestos
containing material (RACM) and complies with all of the
reporting, removal, handling, and disposal requirements for
RACM.
•
Add an exemption to the sampling and analysis requirements if
the owner or operator assumes the materials present contain
asbestos. Any material assumed to contain asbestos does not
have to be sampled and analyzed by a laboratory but a
determination of its condition and category must still be made.
•
Add a provision to require the re-inspection of all non-friable
asbestos containing material identified during the initial
inspection if more than 5 years elapses between the date of the
initial inspection and the date when the demolition or renovation
activity will commence.
•
Add a provision to require the inspection of any new materials
that are installed in the facility between the date when the facility
was inspected for the presence of asbestos and the date when
demolition or renovation activities will commence.
•
Clarify the notification requirements for demolition and
renovation projects.
•
Clarify the viewing device requirements. Viewing devices shall
allow the Control Officer to view the asbestos containing waste
material and the area where RACM is stripped, removed, or
otherwise handled or disturbed without entering the contained
area.

•
Add an exemption from viewing device requirement for projects
that are easily viewable and for projects where the installation of a
viewing device is infeasible.
Support/Opposition: 
During the rulemaking process, the MCAQD has received 
written feedback from three (3) stakeholders. One (1) 
stakeholder expressed support for the proposed revisions and 
two (2) stakeholders expressed neither support nor 
opposition to the proposed revisions.

Explanation of the rule, including the control officer's reasons for initiating the
rulemaking:
Rule 370 establishes performance standards for federally listed hazardous air pollutants.
Most of the performance standards in Rule 370 are National Emission Standards for
Hazardous Air Pollutants (NESHAP) which are promulgated by the U.S. Environmental
Protection Agency and are incorporated by reference into Rule 370. Section 301.9 of Rule
370 incorporates the asbestos NESHAP by reference and includes additional requirements
for demolition and renovation projects in Maricopa County.
In this rulemaking, the MCAQD is proposing to revise the local asbestos provisions in
Section 301.9 of Rule 370 to clarify the requirements for demolition and renovation projects
in Maricopa County and to remove requirements that are not protective of public health.
Additional revisions are also being proposed under Sections 100 and 200 of the rule. With
these revisions, Maricopa County will improve and enhance the rule as it pertains to the
regulation of asbestos.
The proposed revisions to Rule 370 include the following:

Add Section 104 (Exemptions) to exempt demolition and renovation projects from
the requirements of Section 301.9 which take place on a single owner-occupied solely
residential parcel which contains 4 or fewer detached dwelling units.

Add the following definitions: AHERA Contractor/Supervisor, AHERA Building
Inspector, AHERA Worker, and Dwelling Unit.

Remove the following definitions: Existing Source, Federally Listed Hazardous Air
Pollutant, Hazardous Air Pollutant, Major Source, Modification, NESHAP, New
Source and Stationary Source.

Revise the definition of Government-Issued Photo Identification Card to delete
address from the list of information that needs to be provided on a government-
issued photo ID.

Clarify the inspection, sampling, and reporting requirements for asbestos.

Delineate allowable laboratory test methods that can be used to determine the
presence of asbestos in sampled material.

commencement of renovation or demolition activity. A thorough inspection of a
facility is still required before the commencement of renovation or demolition
activity, but it does not necessarily need to occur within 12 months of
commencement of renovation or demolition activity.

complies with all of the reporting, removal, handling, and disposal requirements for 
RACM. 
 Add an exemption to the sampling and analysis requirements if the owner or 
operator assumes the materials present contain asbestos. Any material assumed to 
contain asbestos does not have to be sampled and analyzed by a laboratory but a 
determination of its condition and category must still be made. 
 Add a provision to require the re-inspection of all non-friable asbestos containing

the facility between the date when the facility was inspected for the presence of 
asbestos and the date when demolition or renovation activities will commence. 
 Clarify the notification requirements for demolition and renovation projects. 
 Clarify the viewing device requirements. Viewing devices shall allow the Control 
Officer to view the asbestos containing waste material and the area where RACM is 
stripped, removed, or otherwise handled or disturbed without entering the contained 
area. 
 Add an exemption from viewing device requirement for projects that are easily 
viewable and for projects where the installation of a viewing device is infeasible.

An identification of the persons who will be directly affected by, bear the costs of or 
directly benefit from the proposed rulemaking. 
This rulemaking will directly affect owners of buildings and facilities in Maricopa County 
that contain asbestos as well as contractors who conduct renovation and demolition 
activities. 
A cost benefit analysis of the following: 
(a) The probable costs and benefits to the implementing agency and other agencies 
directly affected by the implementation and enforcement of the proposed 
rulemaking. 
This rulemaking should not impose any new costs on the MCAQD or on any other 
agencies affected by the proposed rulemaking.

(b) The probable costs and benefits to a political subdivision of this state directly 
affected by the implementation and enforcement of the proposed rulemaking. 
This rulemaking should not impose any new costs on political subdivisions of this state 
affected by the proposed rulemaking. 
(c) The probable costs and benefits to businesses directly affected by the proposed 
rulemaking, including any anticipated effect on the revenues or payroll 
expenditures of employers who are subject to the proposed rulemaking. 
This rulemaking should not impose any new costs on businesses in Maricopa County. 
The removal of certain provisions (such as the 12 month inspection requirement) will 
benefit businesses that conduct renovation or demolition work by extending the validity 
of their initial inspection for up to five years which will allow them to avoid additional 
costs associated with reinspection if work is not started within 12 months of the initial 
inspection. 
A general description of the probable impact on private and public employment in 
businesses, agencies and political subdivisions of this state directly affected by the 
proposed rulemaking. 
This rulemaking should have no impact on private or public employment in businesses, 
agencies, and political subdivisions of this state. 
A statement of the probable impact of the proposed rulemaking on small businesses. 
The statement shall include: 
(a) An identification of the small businesses subject to the proposed rulemaking. 
Small business owners that may be subject to the proposed rulemaking include owners of 
commercial or residential properties and small contracting and consulting businesses. 
(b) The administrative and other costs required for compliance with the proposed 
rulemaking. 
This rulemaking does not impose any significant new costs for small businesses. 
(c) A description of the methods that the agency may use to reduce the impact on 
small businesses. 
i. Establish less stringent compliance or reporting requirements in the rule for 
small businesses. 
This rulemaking does not impose any significant new compliance requirements on 
small businesses and does not establish any significant new reporting requirements 
for small businesses. 
ii. Establish less stringent schedules or deadlines in the rule for compliance or 
reporting requirements for small businesses. 
This rulemaking does not impose any significant new compliance requirements on 
small businesses and does not establish any significant new reporting requirements 
for small businesses.

operational standards in the rule. 
This rulemaking does not impose any new design or operational requirements on 
small businesses.

consumers. 
A statement of the probable effect on state revenues. 
The rulemaking will not impose increased monetary or regulatory costs on other state 
agencies, political subdivisions of this state, persons, or individuals so regulated. Without 
costs to pass through to customers, there is no projected change in consumer purchase 
patterns and, thus, no impact on state revenues from sales taxes. 
A description of any less intrusive or less costly alternative methods of achieving the 
purpose of the proposed rulemaking, including the monetizing of the costs and 
benefits for each option and providing the rationale for not using nonselected 
alternatives.

8. 
Such other matters as are prescribed by statute and that are applicable to the county 
or to any specific rule or class of rules:

Under A.R.S. § 49-479(C), a county may not adopt a rule or ordinance that is more stringent 
than the rules adopted by the Director of the Arizona Department of Environmental Quality 
(ADEQ) for similar sources unless it demonstrates compliance with the applicable 
requirements of A.R.S. §49-112. 
§ 49-112 County regulation; standards 
§ 49-112(A) 
When authorized by law, a county may adopt a rule, ordinance or 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 
requirements are met: 
1. The rule, ordinance or regulation is necessary to address a peculiar local condition. 
2. There is credible evidence that the rule, ordinance or 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 regulation is equivalent to federal 
statutes or regulation. 
3. Any fee or tax adopted under the rule, ordinance or regulation does not exceed the 
reasonable costs of the county to issue and administer the permit or plan approval 
program. 
§ 49-112(B) 
When authorized by law, a county may adopt rules, ordinances or 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 regulation that does not exceed the reasonable costs of the county to 
issue and administer that permit or plan approval program. 
The MCAQD is in compliance with A.R.S. § 49-479(C) as the proposed revisions to Rule 
370 would not be making the rule any stricter. The rulemaking is intended to clarify the 
requirements for demolition and renovation projects in Maricopa County and to remove 
requirements that are not protective of public health.

explanatory statement, as prescribed by A.R.S. § 49-471.07, subsection B: 
i.
A description of any change between the proposed rule or ordinance, the final
rule or ordinance or notice of final supplemental rule or ordinance.
No changes were made after the Notice of Proposed Rulemaking was published on
October 27, 2021.
ii. A summary of the comments and arguments for and against the notice and
the county’s response to the comments and arguments.
The following discussion evaluates the arguments for and against the rule and
includes responses to comments received on the proposed rule or the preamble in
the Notice of Proposed Rulemaking. The MCAQD received written comments from
three (3) stakeholders. All of the comments were reviewed and evaluated by the
MCAQD.
Comment #1: [Our City] appreciates this opportunity to provide comments
regarding the proposed revisions to Rule 370. The City has reviewed the proposed
changes and agrees with the elimination of the 12-month inspection requirement
coupled with the incorporation of a 5-year reinspection requirement for non-friable
ACM and the requirement to inspect new materials. The City agrees this will ease the
regulatory burden while still protecting the environment and health. The City also
agrees with the proposed revision that ordered demolitions will no longer be exempt
from the use of amended water, as using amended water is a best management
practice that is protective of the environment. The City supports the proposed
revisions to Rule 370. These revisions clarify requirements and reduce duplication.
Response #1: The MCAQD appreciates your support for the proposed changes. 
The exemption for the use of amended water for ordered demolitions was
re-inserted into the draft rule as the Maricopa County Moratorium on Increased 
Regulatory Burden prevents the MCAQD from making the rule more stringent.
Comment #2: Sec. 104 (Exemptions)
Changes the wording so that 4 separate buildings would be exempt instead of 1
building with 4 units.
-
Can a delegated jurisdiction circumvent the federal regulation? 
-
Is this circumvention? 
-
Is this like a “homestead exemption”? 
-
Or, is this actually exempting up to 4 buildings at one demo site?

(All references of “fully comply with all requirements of 40 CFR 61, Subpart M” 
have been removed (?)). 
(I need to research and collect ADIs and FR notices on the subject.) 
(I know that one of EPA’s justifications for the single residential building exemption 
was the national health agency at the time ruled that the demolition or renovation of 
a single house would not materially affect the ambient air level of asbestos.) 
Response #2: Thank you for your comment. The MCAQD considered your 
comment and replaced the words “residential buildings” with “dwelling units”. 
Section 104 (Exemptions) now reads as follows: 
Section 301.9 shall not apply to demolition or renovation activity involving 
any single owner-occupied solely residential parcel which contains 4 or fewer 
detached dwelling units. 
All references to “fully comply with all requirements of 40 CFR, Subpart M” were 
not removed. Section 301 of Rule 370 states: “Each owner or operator subject to the 
requirements of the following subparts [including Subpart M] shall comply with the 
requirements of those subparts and the additional requirements set forth herein.” 
Comment #3: Definitions: 
Good definitions of the 3 AHERA certified persons (I, CS, W).  
Does this requirement for and definition of “AHERA Worker” give MCAQD 
authority to cite an owner/operator who employs a worker on a regulated (RACM) 
facility site that is not trained, but has an apparently valid certificate? 
Dwelling Unit: 
As defined here and used in the federal NESHAP definition of “Facility” seem to 
contradict the reasoning behind the Exemption at 104. 
Response #3: Thank you for the comment. Any worker handling or disturbing 
RACM must be certified as either an AHERA worker or an AHERA 
contractor/supervisor. With regards to certification, all AHERA workers and 
contractor/supervisors must make available a legible copy of a current training 
certificate for inspection at all times. The MCAQD may cite an owner/operator who 
employs a worker to handle or disturb RACM that is not AHERA certified. 
The MCAQD revised Section 104 (Exemptions) as follows: 
Section 301.9 shall not apply to demolition or renovation activity involving 
any single owner-occupied solely residential parcel which contains 4 or fewer 
detached dwelling units. 
Comment #4: Good statement under 301.9, a: Definition of a ‘thorough 
inspection’. 
Response #4: The MCAQD appreciates your support for the proposed changes.

Comment #5: Good requirement for an inspection report and the elements of the 
report at 301.9, a, (2) 
Response #5: The MCAQD appreciates your support for the proposed changes. 
Comment #6: Good that the outline parallels the federal reg at 61.145: 
Applicability, Notification, Procedures. It looks intentional. 
Response #6: The MCAQD appreciates your support for the proposed changes. 
Comment #7: Good that it references electronic submittals. 
Response #7: The MCAQD appreciates your support for the proposed changes. 
Comment #8: Good that it clarifies that the rules apply to regulated (RACM) work, 
not non-regulated. 
Response #8: The MCAQD appreciates your support for the proposed changes. 
Comment #9: Good that the paragraph on transport requirements on Cat. 1 and 
Cat. 2 non-friable was removed. It should never have been in the asbestos NESHAP 
reg. 
Response #9: The MCAQD appreciates your support for the proposed changes. 
Comment #10: Good that waste is referred to as ACWM instead of RACM in 
several places. 
Response #10: The MCAQD appreciates your support for the proposed changes. 
Comment #11: I like the work that MCAQD did in cleaning up the local NESHAP. 
It is much more understandable and usable than the previous version. I especially 
like the inclusion of CARB 435 as an acceptable analytical method (not because I am 
a fan of the CARB method, but now we can easily prove that processed vermiculite 
is not ACM, and be done with that). It is easy to see that the goal was to make it 
simpler to understand and comply, instead of prescribing more rules for the sake of 
control as many local jurisdictions have done. 
BUT: we need a clarification of “Exemption”. The intent is probably good, I don’t 
know, but to play with the words of the federal regulation to accomplish a goal is not 
good. I believe that the intent of the federal regulation was always 4 dwelling units in 
a SINGLE building. However, I am all for the concept of a “farmstead exemption” 
Response #11: Thank you for your comment. The MCAQD has considered your 
comment and revised Section 104 (Exemptions) as follows: 
Section 301.9 shall not apply to demolition or renovation activity involving 
any single owner-occupied solely residential parcel which contains 4 or fewer 
detached dwelling units. 
Comment #12: “Section 301.9a: …The requirement to inspect for the presence of 
asbestos shall not apply if the owner or operator assumes that the materials present

are RACM and complies with all requirements that are applicable to the removal, 
handling, and disposal of RACM…” 
[Our City], as an owner and operator of a water and gas utility, is aware of the 
presence of asbestos cement pipe (ACP) and asbestos-containing gas pipe coating 
buried throughout the city. These materials are easily visually identified as asbestos-
containing and in most cases are identified in as-built drawings or in the City’s GIS 
utility maps. As a matter of policy, the City has chosen to forego the traditional 
approach to sampling these materials for confirmation of asbestos content, and we 
assume that they contain asbestos and treat them as non-regulated Category II Non-
Friable asbestos containing materials (ACM). Our interpretation of Section 301.9a 
would be that these policies are no longer allowable as these materials are now to be 
considered regulated ACM (RACM) when asbestos content is assumed. By their 
nature, these materials are generally buried underground, leaving the City with no 
other option than to assume asbestos content absent a qualified inspector’s ability to 
access them prior to a project. According to the language of this section, the 
materials must now be sampled following excavation to eliminate the requirement to 
qualify them as RACM. This is untenable since, at a minimum, a qualified inspector 
must arrive at the site, collect a sample, wait for the laboratory’s report, then issue an 
inspection report in compliance with 301.9a(2)(a)-(d). Lastly, since the designation of 
RACM requires two elements (asbestos contents greater than 1%, and friability – 
ability of the material to be crushed into a powder using hand pressure), an intact 
and assumed asbestos containing material that is not friable should never be 
considered RACM. 
[Our City] respectfully requests that the language of this section be changed to allow 
owners to assume asbestos content of traditionally non-friable asbestos containing 
materials without the automatic assumption that these materials will be considered 
RACM and be required to be removed, handled, and disposed of as such. 
Response #12: Owners and operators may assume materials are asbestos-
containing, however; they cannot assume the condition (i.e. friability) and category of 
the materials without a determination by an AHERA building inspector. A 
determination of the condition and category of the material does not require the 
material be sent to a laboratory. The condition and category can be determined by an 
examination of the material (i.e. can be crumbled, pulverized, or reduced to powder 
by hand pressure) and by considering the activity which will impact it during 
demolition or renovation. Bulk sampling and laboratory testing are only required to 
prove that materials in each homogenous area are not asbestos containing. 
In the case of asbestos containing underground pipes (which are generally 
understood to be non-friable unless discovered to be damaged), only the areas that 
are being cut or broken through mechanical means should be considered in the 
RACM quantification. If the area of pipe being inspected for friability is found to be 
in good condition, then the length of the pipe being removed can be assumed to also 
be non-friable as one homogenous material.

Rule language has been subsequently added to section 301.9a(1)(a) indicating that 
laboratory analysis of a material is not required if it is assumed to be asbestos-
containing material, but that an AHERA building inspector must still provide 
determination and documentation of the condition and category of the material per 
301.9a(2)(c) and (d). Additionally the term “category” has been included within rule 
language of section 301.9a(2)(d) for the purpose of further describing asbestos-
containing material condition during demolition and renovation activities. 
Comment #13: “Section 301.9a(3): If more than 5 years has elapsed between the 
date when the facility was inspected for the presence of asbestos and the date when 
the demolition or renovation activity will commence, the owner or operator shall 
have each non-friable ACM re-inspected by an AHERA building inspector to 
determine if the ACM is still non-friable. This re-inspection shall occur prior to the 
commencement of demolition or renovation activity. The re-inspection must be 
documented in a written report that meets the requirements in Section 301.9(a)(2) of 
this rule.” 
As written, this section indicates that if a facility has been inspected greater than 5 
years prior to the commencement of demolition or renovation activity, then only the 
materials identified as non-friable need to be re-inspected to determine that they 
have not become friable in that time frame. If a qualified inspector were to assess 
that there were no new materials installed and that there were no materials identified 
as non-friable ACM in the original inspection report, the 5-year timeframe appears 
irrelevant. 
[Our City] respectfully requests that the language of this section be clarified to reflect 
Maricopa County’s intent whether an owner is to assess all previously identified 
materials or only the non-friable ACMs after 5 years have elapsed. 
Response #13: The MCAQD reviewed the language in this section and determined 
it is clear as currently written. It is correct that only previously sampled materials that 
were determined to contain non-friable ACM at the time of the initial inspection 
would need to be re-inspected after the five year period has elapsed. This is because 
the condition of ACM can change over time - particularly if the material is exposed 
to heat, sunlight, abrasion, or chemicals – and therefore, would need to be re-
evaluated for friability. Reinspection is not necessary for materials that were 
originally determined to not contain any ACM.

operator of a demolition or renovation activity involving a facility as defined in 40 
CFR 61, Subpart M shall: 
a. Each owner or operator of a demolition activity or renovation activity involving 
a facility as defined in 40 CFR 61, Subpart M shall: Prior to the commencement 
of demolition or renovation activity listed in 40 CFR 61.145(a)(1)-(4), thoroughly 
inspect the facility, or the part of the facility where demolition activity or 
renovation activity will occur, for the presence of asbestos, including Category I 
and Category II nonfriable asbestos-containing material (ACM) and regulated 
asbestos-containing material (RACM). For the purpose of this rule, thoroughly 
inspect means that all ACM has been identified and quantified, and all RACM 
has been accurately categorized. The requirement to inspect for the presence of 
asbestos shall not apply if the owner or operator assumes that the materials 
present are RACM and complies with all requirements that are applicable to the 
removal, handling, and disposal of RACM. In addition:

(1) Fully comply with all requirements of 40 CFR 61, Subpart M. The thorough 
inspection for the presence of asbestos must be conducted by an AHERA 
building inspector. 
(a) An AHERA building inspector may assume a given material contains 
asbestos. Any material assumed to contain asbestos does not have to be 
sampled and analyzed by a laboratory but a determination of its condition 
(i.e. friability) and category must be made and documented as specified in 
301.9(a)(2)(c) and (d). 
(2) Thoroughly inspect the facility within 12 months of commencement of 
demolition or renovation activity for the presence of asbestos, including 
Category I and Category II nonfriable ACM. Include the date of this 
inspection on the written notification. The inspection for the presence of 
asbestos must be documented in a written report that meets all of the 
following requirements: 
(a) Clearly identifies all materials that were sampled and provides a legible 
copy of the laboratory chain of custody indicating who collected the 
samples; 
(b) Includes analytical results from a laboratory accredited by the National 
Voluntary Laboratory Accreditation Program (NVLAP) showing that 
samples analyzed for the presence of asbestos were analyzed using one of 
the following test methods: 
(i) Interim Method of the Determination of Asbestos in Bulk 
Insulation Samples (as specified in Appendix E to Subpart E of 40 
CFR Part 763); 
(ii) Method for the Determination of Asbestos in Bulk Building 
Materials (EPA/600/R-93/116); 
(iii) Electron Microscopy Analytical Method, as described in 
EPA/600/R-93/116; or 
(iv) Determination of Asbestos Content of Serpentine Aggregate 
(California Air Resources Board Test Method 435), when applicable. 
(c) Categorizes all ACM as Category I nonfriable ACM, Category II 
nonfriable ACM, or RACM, in accordance with the definitions in 40 
CFR 61, Subpart M; and 
(d) Clearly describes and identifies the location, condition, category, and 
quantity of all ACM. Determination of the category of the material must 
take into account the condition of the material during the demolition and 
renovation activity. 
(3) If more than five (5) years has elapsed between the date when the facility was 
inspected for the presence of asbestos and the date when the demolition or 
renovation activity will commence, the owner or operator shall have each 
non-friable ACM re-inspected by an AHERA building inspector to 
determine if the ACM is still non-friable. This re-inspection shall occur prior 
to the commencement of demolition or renovation activity. The re-

inspection must be documented in a written report that meets the 
requirements in Section 301.9(a)(2) of this rule. 
(4) If new materials are installed in the facility between the date when the facility 
was inspected for the presence of asbestos and the date when the demolition 
or renovation activity will commence, the owner and operator shall have 
each new material inspected for the presence of asbestos by an AHERA 
building inspector prior to the commencement of demolition or renovation 
activity. The inspection of new materials must be documented in a written 
report that meets the requirements in Section 301.9(a)(2) of this rule. 
(5) Each owner and operator shall maintain a complete copy of the written 
report required by Sections 301.9(a)(2), 301.9(a)(3), and 301.9(a)(4) of this 
rule for two years from the completion of the demolition or renovation 
activity. A complete copy of each written report shall be on-site and available 
for inspection during all demolition and renovation activities. 
b. Prior to the commencement of any demolition or renovation activity listed in 40 
CFR 61.145(a)(1)-(4), provide the Control Officer with notification of intention 
to demolish or renovate in the manner described in 40 CFR 61.145(b). In 
addition: 
(1) The written notification shall include the date on which the facility was 
inspected for the presence of asbestos. 
(2) The written notification shall be submitted through MCAQD’s online user 
portal with a verified CROMMER signature. 
(3) At the time when the written notification is provided to the Control Officer, 
a copy of the applicable written report(s) required by Sections 301.9(a)(2), 
301.9(a)(3), and 301.9(a)(4) of this rule shall be in the possession of the 
owner or operator. The owner or operator shall make the written report 
available without delay upon request of the Control Officer. 
(4) Update all notifications in accordance with 40 CFR 61.145(b). For 
renovations All notifications, excluding notifications for renovation 
operations described in 40 CFR 61.145(a)(4)(iii), notifications shall expire 
every December 31, with new notices required at least 10 working days 
before the end of the calendar year preceding the year for which notice is 
being given. All other notifications shall expire one year from either the 
original postmark date or commercial delivery date or date of hand delivery 
to the Control Officer. the date of electronic submittal with a verified 
CROMMER signature. 
(5) For a demolition activity or renovation activity that continues beyond the 
expiration date, the owner or operator of the demolition or renovation 
activity shall notify submit a new notification to the Control Officer in 
accordance with 40 CFR 61.145(b) at least 10 working days prior to the 
expiration of the original notice and pay all applicable fees prescribed by Rule 
280 of these rules. 
(6) Notifications for renovation operations described in 40 CFR 61.145(a)(4)(iii) 
shall be submitted at least 10 working days before the end of the calendar

year preceding the year for which notice is being given and shall expire on 
December 31 of the calendar year for which notice is given.

designed as to allow an inspector the Control Officer to view the facility 
from the outside asbestos-containing waste material (ACWM) and the area 
where RACM is stripped, removed, or otherwise handled or disturbed 
without entering the contained area where the ACWM is stored and the 
activity is occurring, either through ports or by video monitoring. Viewing 
devices are not required if walls or other barriers do not prevent the Control 
Officer from viewing the area where ACWM is stored and the area where 
RACM is stripped, removed, or otherwise handled or disturbed. Viewing 
devices are not required if the installation or use of a viewing device is 
infeasible for a specific area where RACM will be stripped, removed, or 
otherwise handled or disturbed. 
(c) 
(4) All exposed RACM subject to cutting or dismantling demolition or 
renovation operations and all RACM being removed from a facility or a 
facility component shall be kept adequately wet by using amended water to 
control the release of asbestos fibers, except as provided below:. 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 exemptions are listed under 40 CFR 61.145(c)(3)(i)(A), 
40 CFR 61.145(c)(3)(ii) and/or 40 CFR 61.145(c)(7)(i). To claim these

exemptions, the owner or operator shall follow the requirements of 40 CFR 
61.145(c)(3)(i)(B), 40 CFR 61.145(c)(3)(iii) and/or 61.145(c)(7)(ii) and (iii). 
(a) The use of amended water is not required when the owner or operator 
has obtained prior written approval from the Administrator based on a 
written application that wetting would unavoidably damage equipment 
or present a safety hazard, however the owner or operator shall comply 
with 40 CFR 61.145(c)(3)(i)(B) or 40 CFR 61.145(c)(3)(ii) and (iii); and 
(b) The use of amended water is not required when the temperature at the 
point of wetting is below 32 °F (0 °C), however the owner or operator 
shall comply with 40 CFR 61.145(c)(7)(ii) and (iii). 
(c) The use of amended water is not required for ordered demolitions, as 
defined in 40 CFR 61.145(a)(3). 
(d) 
(5) All RACM ACWM shall be contained in transparent, leak-tight wrapping and 
shall remain adequately wet to prevent dust emissions during removal, 
transport, storage, and proper landfill disposal following local, county, state, 
and federal regulations. Affix a visible and legible label to each individual 
wrapping with the name of thesite owner or operator waste generator and 
the name and address of the location of the facility that generated the RACM

CFR 61, Subpart M shall: 
a. Prior to the commencement of demolition or renovation activity listed in 40 
CFR 61.145(a)(1)-(4), thoroughly inspect the facility, or the part of the facility 
where demolition activity or renovation activity will occur, for the presence of 
asbestos, including Category I and Category II nonfriable asbestos-containing 
material (ACM) and regulated asbestos-containing material (RACM). For the 
purpose of this rule, thoroughly inspect means that all ACM has been identified 
and quantified, and all RACM has been accurately categorized. The requirement 
to inspect for the presence of asbestos shall not apply if the owner or operator 
assumes that the materials present are RACM and complies with all requirements 
that are applicable to the removal, handling, and disposal of RACM. In addition: 
(1) The thorough inspection for the presence of asbestos must be conducted by 
an AHERA building inspector. 
(a) An AHERA building inspector may assume a given material contains 
asbestos. Any material assumed to contain asbestos does not have to be 
sampled and analyzed by a laboratory but a determination of its condition 
(i.e. friability) and category must be made and documented as specified in 
301.9(a)(2)(c) and (d). 
(2) The inspection for the presence of asbestos must be documented in a written 
report that meets all of the following requirements: 
(a) Clearly identifies all materials that were sampled and provides a legible 
copy of the laboratory chain of custody indicating who collected the 
samples; 
(b) Includes analytical results from a laboratory accredited by the National 
Voluntary Laboratory Accreditation Program (NVLAP) showing that 
samples analyzed for the presence of asbestos were analyzed using one of 
the following test methods: 
(i) Interim Method of the Determination of Asbestos in Bulk 
Insulation Samples (as specified in Appendix E to Subpart E of 40 
CFR Part 763); 
(ii) Method for the Determination of Asbestos in Bulk Building 
Materials (EPA/600/R-93/116);  
(iii) Electron Microscopy Analytical Method, as described in 
EPA/600/R-93/116; or 
(iv) Determination of Asbestos Content of Serpentine Aggregate 
(California Air Resources Board Test Method 435), when applicable. 
(c) Categorizes all ACM as Category I nonfriable ACM, Category II 
nonfriable ACM, or RACM, in accordance with the definitions in 40 
CFR 61, Subpart M; and 
(d) Clearly describes and identifies the location, condition, category, and 
quantity of all ACM. Determination of the category of the material must

take into account the condition of the material during the demolition and 
renovation activity. 
(3) If more than five (5) years has elapsed between the date when the facility was 
inspected for the presence of asbestos and the date when the demolition or 
renovation activity will commence, the owner or operator shall have each 
non-friable ACM re-inspected by an AHERA building inspector to 
determine if the ACM is still non-friable. This re-inspection shall occur prior 
to the commencement of demolition or renovation activity. The re-
inspection must be documented in a written report that meets the 
requirements in Section 301.9(a)(2) of this rule. 
(4) If new materials are installed in the facility between the date when the facility 
was inspected for the presence of asbestos and the date when the demolition 
or renovation activity will commence, the owner and operator shall have 
each new material inspected for the presence of asbestos by an AHERA 
building inspector prior to the commencement of demolition or renovation 
activity. The inspection of new materials must be documented in a written 
report that meets the requirements in Section 301.9(a)(2) of this rule. 
(5) Each owner and operator shall maintain a complete copy of the written 
report required by Sections 301.9(a)(2), 301.9(a)(3), and 301.9(a)(4) of this 
rule for two years from the completion of the demolition or renovation 
activity. A complete copy of each written report shall be on-site and available 
for inspection during all demolition and renovation activities. 
b. Prior to the commencement of any demolition or renovation activity listed in 40 
CFR 61.145(a)(1)-(4), provide the Control Officer with notification of intention 
to demolish or renovate in the manner described in 40 CFR 61.145(b). In 
addition: 
(1) The written notification must include the date on which the facility was 
inspected for the presence of asbestos. 
(2) The written notification shall be submitted through MCAQD’s online user 
portal with a verified CROMMER signature. 
(3) At the time when the written notification is provided to the Control Officer, 
a copy of the applicable written report(s) required by Sections 301.9(a)(2), 
301.9(a)(3), and 301.9(a)(4) of this rule shall be in the possession of the 
owner or operator. The owner or operator shall make the written report 
available without delay upon request of the Control Officer. 
(4) All notifications, excluding notifications for renovation operations described 
in 40 CFR 61.145(a)(4)(iii), shall expire one year from the date of electronic 
submittal with a verified CROMMER signature. 
(5) For a demolition activity or renovation activity that continues beyond the 
expiration date, the owner or operator of the demolition or renovation 
activity shall submit a new notification to the Control Officer in accordance 
with 40 CFR 61.145(b) prior to the expiration of the original notice. 
(6) Notifications for renovation operations described in 40 CFR 61.145(a)(4)(iii) 
shall be submitted at least 10 working days before the end of the calendar

year preceding the year for which notice is being given and shall expire on 
December 31 of the calendar year for which notice is given. 
(7) Pay all applicable fees prescribed by Rule 280 of these rules. 
c. Comply with the following requirements for any demolition or renovation 
activities listed in 40 CFR 61.145(a)(1), 40 CFR 61.145(a)(3), and 40 CFR 
61.145(a)(4): 
(1) Any person that strips, removes, or otherwise handles or disturbs any RACM 
shall be an AHERA worker or an AHERA contractor/supervisor. In 
addition: 
(a) At least one AHERA contractor/supervisor shall be on-site at all times 
when RACM is stripped, removed, or otherwise handled or disturbed. 
(b) A legible copy of the current training certificate for each AHERA worker 
and each AHERA contractor/supervisor shall be available for inspection 
at all times. 
(c) Clearly visible and legible photo identification for each AHERA worker 
and each AHERA contractor/supervisor shall be on-site and available 
for inspection, upon the request of the Control Officer, at all times when 
RACM is stripped, removed, or otherwise handled or disturbed. The 
photo identification shall be from the trainer who provided training in 
accordance with Appendix C to 40 CFR 763, Subpart E, or a current 
government-issued photo identification card. 
(2) All RACM, including Category I nonfriable ACM and Category II nonfriable 
ACM that have become friable, shall be contained in transparent, leak-tight 
wrapping and shall remain adequately wet to prevent emissions during 
removal, transport, storage, and proper landfill disposal in accordance with 
local, county, state, and federal regulations. 
(3) Inspection viewing devices are required at all times when RACM is stripped, 
removed, or otherwise handled or disturbed.  Viewing devices shall allow the 
Control Officer to view the asbestos-containing waste material (ACWM) and 
the area where RACM is stripped, removed, or otherwise handled or 
disturbed without entering the contained area where the ACWM is stored 
and the activity is occurring, either through ports or by video monitoring. 
Viewing devices are not required if walls or other barriers do not prevent the 
Control Officer from viewing the area where ACWM is stored and the area 
where RACM is stripped, removed, or otherwise handled or disturbed. 
Viewing devices are not required if the installation or use of a viewing device 
is infeasible for a specific area where RACM will be stripped, removed, or 
otherwise handled or disturbed. 
(4) All exposed RACM subject to demolition or renovation operations and all 
RACM being removed from a facility or a facility component shall be kept 
adequately wet by using amended water to control the release of asbestos 
fibers, except as provided below: 
(a) The use of amended water is not required when the owner or operator 
has obtained prior written approval from the Administrator based on a

written application that wetting would unavoidably damage equipment or 
present a safety hazard, however the owner or operator shall comply with 
40 CFR 61.145(c)(3)(i)(B) or 40 CFR 61.145(c)(3)(ii) and (iii); and 
(b) The use of amended water is not required when the temperature at the 
point of wetting is below 32 °F (0 °C), however the owner or operator 
shall comply with 40 CFR 61.145(c)(7)(ii) and (iii). 
(c) The use of amended water is not required for ordered demolitions, as 
defined in 40 CFR 61.145(a)(3). 
(5) All ACWM shall be contained in transparent, leak-tight wrapping and shall 
remain adequately wet to prevent emissions during removal, transport, 
storage, and proper landfill disposal following local, county, state, and federal 
regulations. Affix a visible and legible label to each individual wrapping with 
the name of the waste generator and the name and location of the facility 
that generated the ACWM.

Public Health Finance Update –  3rd Qtr FY21
Mr. Scot Pitcairn 
Mr. Pitcairn provided the Board with an update of Public Health’s fiscal year 2021 – 3rd Quarter Budget Status 
report for:  
•
Fund 100 – General Fund
•
Fund 200 – Coronavirus Fund/CARES Act Funding
•
Fund 265 – Special Revenue Fund
•
Fund 532 - Grant Fund
(refer to agenda packet for PHS finance memo and report summary) 
A discussion was had concerning Fund 200 to better understand the recovery ACT and spending. Mr. Porter 
explained the CARES ACT funding extends to December 2021; however, funds are expected to be expended by 
June 30. The recovery dollars were already added to the county for next year's budget.  Ms. Bohn provided 
additional insight. The intent is to have the monies fully spent by end of June; Maricopa County has prioritized 
the pandemic response with said funds. The new American rescue plan act funds, Maricopa County is slated to 
receive about 870 million, with the first half expected within the next two weeks, federal guidance will detail 
how funds are to be used.   Additional funds are expected for use for non-related pandemic events.  
Arizona is expecting 4.8 billion, a lot of the funds are dedicated towards vaccines, contract tracing, and other 
Public Health specific programs. It’s expected that a portion of said funds will flow down to Public Health 
agencies. It’s expected that Public Health will have a lot of opportunities to put programs into place. 
Mr. Porter further explained that a lot of the funds will be expended through the grant dollars coming into the 
department. The above baseline general funds will be ongoing dollars year after year. Most of the funds will be 
expended through the department. Some items are already established through the CARES ACT funding. The 
budget office is recommending keeping those General Fund positions on an ongoing basis beyond the COVID 
grant dollars. 
President Macmillan asked if there was both a motion to approve the Public Health finance report and if 
anyone wanted to make a recommendation to the Board of Supervisors to approve the Public Health FY22 
budget request as recommended by the Maricopa County Budget Office. Ms. Schaffer made a motion to 
approve the budget as presented, Mr. Cassano seconded the motion. The motion passed unanimously.

Air Quality Department – Make a recommendation to the Board of Supervisors to approve the proposed
revisions to the following rules:
A. AQ-2017-007 
Rule 322 (Power Plant Operations) 
Rule 323 (Fuel Burning Equipment from Industrial/Commercial/Institutional (ICI) Sources) 
Rule 324 (Stationary Reciprocating Internal Combustion Engines (RICE)). 
Mr. Verkamp explained each rule as presented. The department is proposing to revise these rules, to 
address rule deficiencies identified by the EPA. Proposed revisions are required to secure the approval 
of the rules as part of the Arizona State Implementation Plan under the Federal Clean Air Act. The 
Department's also proposing revisions to address recommendations provided by the EPA, incorporate 
revisions recommended by stakeholders and make revisions to improve and clarify the rules. The 
department has held stakeholders’ workshops for all the rules to discuss the proposed revisions with 
stakeholders’. Notices of the rulemakings were posted on the Maricopa County Enhanced Regulatory 
Outreach Program website, for stakeholders to review and comment on the revisions. 
The Air Quality Department received a public comment shortly before the posting deadline for their 
reports, revisions to address the comment were forwarded to all board members earlier today. 
Specifically, the department added language to Section 102.1 D regarding the applicability of the non-
road engine records requirement in  Rule 324, basically narrowing it down to just those types of 
engines that are kind of like generators. The department advised that they didn't want to be regulating 
non-road engines such as backhoes and bulldozers. A revision to Section 502.6 of Rule 324 was also 
made. It now reads as follows:  An owner-operator of a non-road engine shall maintain the following 
records for each non-road engine. A, date that each engine is brought to the stationary source, and B, 
for are engines located at a stationary source greater than 14 consecutive days.

•
Owners must maintain records of the make model, serial number, and rated capacity of the
engine.
•
The date of each instance in which the engine is moved from its existing location, and the
reason why the engine was moved; and
•
Fuel type and sulfur content of the fuel
The language “for engines located at the stationary source greater than 14 consecutive days”, was 
added to limit the record-keeping requirement for those non-road engines such as  rentals – so of 
stakeholders not having to keep all these records for just a rental generator that came and went off on-
site, very quickly.   The department spoke with the stakeholder who submitted this comment last week 
and they were satisfied with the revisions that we made to address their concerns. Additional 
discussions were had concerning ASU turbine and which rule their equipment falls under. 
President MacMillan asked if anyone wanted to make a recommendation to the Board of Supervisors to 
approve the revisions to Rule 322,  as presented. The recommendation was made  by Ms. Schaffer and 
seconded by Mr. Cassano . The  recommendation passed unanimously. 
President MacMillan asked if anyone wanted to make a recommendation to the Board of Supervisors to 
approve the revisions to Rule 323 as presented. The recommendation was made by Ms. Schaffer and 
seconded by Mr. Cassano. The recommendation passed unanimously. 
President MacMillan asked if anyone wanted to make a recommendation to the Board of Supervisors to 
approve the revisions to Rule 324 as presented. The recommendation was made by Ms. Schaffer and 
seconded by Mr. Cassano. The recommendation passed unanimously. 
The Air Quality Department respectfully asks the Board to approve their request of a recommendation 
to the Board of Supervisors to approve the revisions to Rule: 
B. AQ-2017-008 
Rule 336 (Surface Coating Operations) 
A discussion was had about changes with Rule 336. The department had no oppositions or comments on Rule 
336. The proposed rulemaking will be published as a part of the Report to the Board of Supervisors on the  EROP 
website for a public comment period before the public hearing. 
President MacMillan asked if anyone wanted to make a recommendation to the Board of Supervisors to 
approve the revisions to Rule 336 as presented. The recommendation was made by Ms. Schaffer and 
seconded by Mr. Cassano. The recommendation passed. There was one Nye by Mr. Macmillan.  
Air Quality Department requests Board of Health approval of the expedited process rulemaking for Rule 
370. 
C. AQ-2019-003

presented. Ms. Schaffer made a motion to approve the expedited process rulemaking for Rule 370 and Mr. 
Cassano seconded the motion.  The motion passed unanimously.

Fee Waiver Applications – Twenty-three (23) permit fee waivers
Mr. Ken Conklin 
Fee Waiver Application Summary Sheet and Fee Waiver Staff Report
(refer to agenda packet for memo and finance summary) 
Mr. Conklin presented a summary of documents previously distributed to the Board on the 23 Permit Fee 
Waiver applications and referred all to the Fee waiver Application Summary sheet and Staff Report, noting that 
all 23 met the Maricopa County Environmental Services Health Code Chapter 1. Regulation 5.  Only an operator 
of a charitable non-profit establishment, which operates to provide relief to the solely distressed or 
underprivileged my apply to the Board of Health for the waiver of a permit fee. A waiver may be granted only if 
the operator maintains a current 501 (c)3 tax-exempt status. This demonstrates that the payment of the said fee 
will cause financial hardship. The Board was asked to approve P1-P20 and C1-C3 on the fee waiver applications 
submitted.  
President MacMillan asked if there was a motion to approve the 23 fee waiver applications presented as P1 
through P20 and C1 through C3. A Motion was made by Mr. Celley to approve the 23 fee waiver permits and 
seconded by Mr. Cassano. All were in favor, the motion carried.

RE: Rule 370 proposed changes 
Dear Mr. McNeely: 
The City of Phoenix (City) appreciates this opportunity to 
provide comments regarding the proposed revisions to Rule 
370. The City has reviewed the proposed changes and agrees 
with the elimination of the 12-month inspection requirement 
coupled with the incorporation of a 5-year reinspection 
requirement for non-friable ACM and the requirement to inspect 
new materials. The City agrees this will ease the regulatory 
burden while still protecting the environment and health. The 
City also agrees with the proposed revision that ordered 
demolitions will no longer be exempt from the use of amended 
water, as using amended water is a best management practice 
that is protective of the environment. The City supports the 
proposed revisions to Rule 370. These revisions clarify 
requirements and reduce duplication. Please contact Elizabeth 
Zima at elizabeth.zima@phoenix.gov if you have any 
questions. 
Sincerely, 
Nancy Allen

2021 proposed MCAQD NESHAP revision.docx 
Email not displaying correctly? View it in your browser.

4/20/21 
Notes 
MC AQD proposed revisions to local NESHAP 
1. Sec. 104 (Exemptions)
Changes the wording so that 4 separate buildings would be exempt instead of 1
building with 4 units.
- 
Can a delegated jurisdiction circumvent the federal regulation?
- 
Is this circumvention?
- 
Is this like a “homestead exemption”?
- 
Or, is this actually exempting up to 4 buildings at one demo site?
(All references of “fully comply with all requirements of 40 CFR 61, Subpart M”
have been removed (?)).
(I need to research and collect ADIs and FR notices on the subject.)
(I know that one of EPA’s justifications for the single residential building
exemption was the national health agency at the time ruled that the demolition or
renovation of a single house would not materially affect the ambient air level of
asbestos.)
2. Definitions:
Good definitions of the 3 AHERA certified persons (I, CS, W).
Does this requirement for and definition of “AHERA Worker” give MCAQD
authority to cite an owner/operator who employs a worker on a regulated (RACM)
facility site that is not trained, but has an apparently valid certificate?
Dwelling Unit:
As defined here and used in the federal NESHAP definition of “Facility” seem to
contradict the reasoning behind the Exemption at 104.
3. Good statement under 301.9, a: Definition of a ‘thorough inspection’.
4. Good requirement for an inspection report and the elements of the report at
301.9, a, (2)
5. Good that the outline parallels the federal reg at 61.145: Applicability,
Notification, Procedures. It looks intentional.
6. Good that it references electronic submittals.

Return to Comment #6
Return to Comment #7

7. Good that it clarifies that the rules apply to regulated (RACM) work, not non-
regulated.
8. Good that the paragraph on transport requirements on Cat. 1 and Cat. 2 non-
friable was removed. It should never have been in the asbestos NESHAP reg.
9. Good that waste is referred to as ACWM instead of RACM in several places.
10. I like the work that MCAQD did in cleaning up the local NESHAP. It is much
more understandable and usable than the previous version. I especially like the 
inclusion of CARB 435 as an acceptable analytical method (not because I am a 
fan of the CARB method, but now we can easily prove that processed vermiculite 
is not ACM, and be done with that). It is easy to see that the goal was to make it 
simpler to understand and comply, instead of prescribing more rules for the sake 
of control as many local jurisdictions have done. 
BUT: we need a clarification of “Exemption”. The intent is probably good, I don’t 
know, but to play with the words of the federal regulation to accomplish a goal is 
not good. I believe that the intent of the federal regulation was always 4 dwelling 
units in a SINGLE building. However, I am all for the concept of a “farmstead 
exemption”

City of Mesa’s Comments to Proposed Maricopa County Rule 370 
Rulemaking 
The City of Mesa appreciates this opportunity to provide comments during this phase of 
Maricopa County’s Rule 370 rulemaking process.  The City takes pride in our robust 
environmental management programs and we value our relationship with Maricopa 
County’s regulating bodies.  Representatives from various departments within the City of 
Mesa have had the opportunity to review the proposed revisions to Rule 370 and we are 
in general agreement with the breadth and intent of the revisions.  Because it has been 
several years since any revisions have been made to Rule 370, the City supports 
Maricopa County’s efforts to streamline and clarify various portions of the rule.  The City 
has identified two sections of the proposed revisions that are relevant to our operations 
and that can financially and operationally impact our policies and procedures.  A 
discussion of our comments is below.  
Comment 1: 
Section 301.9a: …The requirement to inspect for the presence of asbestos shall not 
apply if the owner or operator assumes that the materials present are RACM and 
complies with all requirements that are applicable to the removal, handling, and disposal 
of RACM… 
The City of Mesa, as an owner and operator of a water and gas utility, is aware of the 
presence of asbestos cement pipe (ACP) and asbestos-containing gas pipe coating

buried throughout the city.  These materials are easily visually identified as asbestos-
containing and in most cases are identified in as-built drawings or in the City’s GIS utility 
maps.  As a matter of policy, the City has chosen to forego the traditional approach to 
sampling these materials for confirmation of asbestos content, and we assume that they 
contain asbestos and treat them as non-regulated Category II Non-Friable asbestos 
containing materials (ACM).  Our interpretation of Section 301.9a would be that these 
policies are no longer allowable as these materials are now to be considered regulated 
ACM (RACM) when asbestos content is assumed.  By their nature, these materials are 
generally buried underground, leaving the City with no other option than to assume 
asbestos content absent a qualified inspector’s ability to access them prior to a project. 
According to the language of this section, the materials must now be sampled following 
excavation to eliminate the requirement to qualify them as RACM.  This is untenable 
since, at a minimum, a qualified inspector must arrive at the site, collect a sample, wait 
for the laboratory’s report, then issue an inspection report in compliance with 
301.9a(2)(a)-(d).  Lastly, since the designation of RACM requires two elements 
(asbestos contents greater than 1%, and friability – ability of the material to be crushed 
into a powder using hand pressure), an intact and assumed asbestos containing material 
that is not friable should never be considered RACM. 
The City of Mesa respectfully requests that the language of this section be 
changed to allow owners to assume asbestos content of traditionally non-friable 
asbestos containing materials without the automatic assumption that these 
materials will be considered RACM and be required to be removed, handled, and 
disposed of as such. 
Comment 2: 
Section 301.9a(3): If more than 5 years has elapsed between the date when the facility 
was inspected for the presence of asbestos and the date when the demolition or 
renovation activity will commence, the owner or operator shall have each non-friable 
ACM re-inspected by an AHERA building inspector to determine if the ACM is still non-
friable. This re-inspection shall occur prior to the commencement of demolition or 
renovation activity. The re-inspection must be documented in a written report that meets 
the requirements in Section 301.9(a)(2) of this rule. 
As written, this section indicates that if a facility has been inspected greater than 5 years 
prior to the commencement of demolition or renovation activity, then only the materials 
identified as non-friable need to be re-inspected to determine that they have not become 
friable in that time frame.  If a qualified inspector were to assess that there were no new 
materials installed and that there were no materials identified as non-friable ACM in the 
original inspection report, the 5-year timeframe appears irrelevant.   
Return to Comment #13

The City of Mesa respectfully requests that the language of this section be 
clarified to reflect Maricopa County’s intent whether an owner is to assess all 
previously identified materials or only the non-friable ACMs after 5 years have 
elapsed. 
Once again, the City of Mesa appreciates the opportunity to comment on the proposed 
revisions to Maricopa County’s Rule 370, and we look forward to continuing our 
productive relationship in the future.
