What is the purpose of the submitted rules?
PM contributes to effects that are harmful to human health and the environment, including premature mortality, aggravation of respiratory and cardiovascular disease, decreased lung function, visibility impairment, and damage to vegetation and ecosystems. Section 110(a) of the CAA requires States to submit regulations that control PM emissions. Each of the submitted rules are discussed below.
Rules 4-2-020 and 4-2-030 are sections of Pinal County Code Chapter 4, Article 2--Fugitive Dust providing a general statement of article applicability within Section 020 and a set of definitions for the article within Section 030.
Rule 2-8-302 is a rule designed to limit the emissions of fugitive dust or particulate matter from construction, roadway building, use and maintenance, and bulk material handling, storage, and transport by subjecting these activities to a twenty percent opacity restriction.
Rule 4-4 is a rule designed to limit the emissions of fugitive dust or particulate matter from commercially operated unpaved parking lots, drive ways, and working yards. Rule 4-4 provisions include a 20% opacity and 0% visible emissions property line standard, silt content and silt loading stabilization standards and requirements for clean-up of material track-out onto paved public roads. The rule also includes requirements for recordkeeping of dust stabilization efforts.
Rule 4-5 is a rule designed to limit the emissions of fugitive dust or particulate matter from residential unpaved parking lots and drive ways. Rule 4-5 provisions include surface stabilization requirements and control measures and requirements for clean-up of material track- out onto paved public roads.
Rule 4-7 is a rule designed to limit the emissions of fugitive dust or particulate matter from development activity related to earthmoving and construction sites such as bulk material hauling, unpaved parking lots, vehicle track-out, and disturbed soil in open areas. Rule 4-7 provisions include a twenty percent opacity and zero percent visible emissions property line standard, requirements to implement Best
Available Control Measures (BACM) for material track-out onto paved public roads, bulk material handling and movement, unpaved roadways and unpaved parking areas on a site. The rule also includes provisions for a dust control permit program, dust control plan requirements, and related recordkeeping requirements.
Rule 4-9 contains the test methods for determining compliance with the opacity and soil stabilization requirements of Rules 4-7, 4-4, and 4-5.
Rules 4-7, 4-4, and 4-5 apply to the Apache Junction portion of
Pinal County within the Phoenix PM Nonattainment Area (NAA), referred to in the rule as T1N R8E (Township 1 North, Range 8 East). The rules do not apply to the remaining portion of Pinal County. These rules are part of the Pinal County contribution to the Phoenix serious area PM-10 attainment plan control strategy.
Rule 2-8-302 applies to the Hayden planning area PM-10 non- attainment area portion of Pinal County defined in 40 CFR 81.303 (See also 72 FR 14422, March 28, 2007). It is neither applicable to the
Apache Junction serious PM-10 non-attainment area, nor the remainder of
Pinal County.
EPA's technical support document (TSD) has more information about these rules.

EPA's Evaluation and Action
-
How is EPA evaluating the rules?
Generally, SIP rules must be enforceable (see section 110(a) of the
Act) and must not relax existing requirements (see sections 110(l) and 193). In addition, SIP rules must implement Reasonably Available
Control Measures (RACM), including Reasonably Available Control
Technology (RACT), in moderate PM nonattainment areas, and Best
Available Control Measures (BACM), including Best Available Control
Technology (BACT), in serious PM nonattainment areas (see CAA sections 189(a)(1) and 189(b)(1)). As mentioned earlier, Pinal County regulates two PM nonattainment areas: The Hayden Area, classified as moderate; and, the Apache Junction area, classified as serious (see 40 CFR part 81). Consequently, Rule 2-8-302 must implement RACM, while Rules 4-7, 4-4, and 4-5 must implement BACM.
Guidance and policy documents that we use to help evaluate specific enforceability and RACM or BACM requirements consistently include the following: 1. Portions of the proposed post-1987 ozone and carbon monoxide policy that concern RACT, 52 FR 45044, November 24, 1987. 2. ``Issues Relating to VOC Regulation Cutpoints, Deficiencies, and
Deviations; Clarification to Appendix D of November 24, 1987 Federal
Register Notice,'' (Blue Book), notice of availability published in the
May 25, 1988 Federal Register. 3. ``Guidance Document for Correcting Common VOC & Other Rule
Deficiencies,'' EPA Region 9, August 21, 2001 (the Little Bluebook). 4. ``State Implementation Plans; General Preamble for the
Implementation of Title I of the Clean Air Act Amendments of 1990,'' 57
FR 13498 (April 16, 1992); 57 FR 18070 (April 28, 1992). 5. ``State Implementation Plans for Serious PM-10 Nonattainment
Areas, and Attainment Date Waivers for PM-10 Nonattainment Areas
Generally; Addendum to the General Preamble for the Implementation of
Title I of the Clean Air Act Amendments of 1990,'' 59 FR 41998 (August 16, 1994). 6. ``PM-10 Guideline Document,'' EPA 452/R-93-008, April 1993. 7. ``Fugitive Dust Background Document and Technical Information
Document for Best Available Control Measures,'' EPA 450/2-92-004,
September 1992.

Do the rules meet the evaluation criteria?
We believe these rules are consistent with the relevant policy and guidance regarding enforceability, RACM, BACM, and SIP relaxations.
On August 1, 2007, EPA gave a limited approval and limited disapproval to rules amending the SIP for Pinal County (see 72 Federal
Register (FR) 41896). For further discussion, please see our October 17, 2006 proposal of this action at 71 FR 60934. In this rulemaking, we identified the deficiencies listed below.
(1) As written, Rule 4-2-020, Section B effectively exempts agricultural activities from the fugitive dust rules without justification.
(2) Rule 4-2-030, Definition 3, defines ``reasonable precaution'' in highly general terms. The term ``reasonable precaution'' is then used in every section of Rule 4-2-040, to define what actions must be taken to mitigate fugitive dust emissions from relevant activities.
This general requirement is not sufficiently clear or enforceable.
(3) Rule 4-2-050 does not contain recordkeeping provisions. The absence of recordkeeping provisions makes the all of the submitted rules difficult to enforce.
Our final action on August 1, 2007 started sanctions clocks as required by Section 179 of the CAA. The first sanctions clock expired on March 1, 2009 and the offset sanctions have been in effect.
Pinal County's submittal of 4-2-020 and 4-2-030 is intended to address and
Page 41359
correct the exemption of agricultural activities from fugitive dust rules. In these submittals, the exemption for agricultural activities at subsection 4-2-020.B, along with the definition of ``normal farm cultural practice'' at subsection 4-2-030.2, were deleted; thus, correcting this deficiency. After the 12/02/02 adoption of this amendment, the Pinal County Governing Board amended its list of SIP measures (Chapter 1, Article 1, Section 105--SIP List) on 01/07/09 to reflect its 12/02/02 action and has submitted this list to EPA.
Pinal County's submittal of Rules 2-8-302, 4-4, 4-5, 4-7, and 4-9 is intended to address and correct the Rule 4-2-030 ``reasonable precautions'' and Rule 4-2-050 recordkeeping deficiencies in our limited disapproval.
Should EPA complete a final approval action on the submitted rules, we will find that Pinal County has corrected the deficiencies described above. Consequently, sanctions will be terminated and our Federal
Implementation Plan (FIP) obligation will be removed.
Today, we are also publishing an interim final determination with this proposal that will stay sanctions during the public comment period and while we review any public comments we may receive.
The TSDs have more information on our evaluation. Because correcting the 4-2-020 and 4-2-030 deficiencies only involved removing the agricultural activities exemption, we have not provided a TSD discussing this amendment to Rules 4-2-020 and 4-2-030.
-
EPA Recommendations To Further Improve the Rules
The TSD for Rule 4-7 describes additional rule revisions that do not affect EPA's current action but are recommended for the next time
Pinal County modifies Rule 4-7 and 4-9. Rule 4-9 contains an editorial error that should be corrected as soon as practicable.
-
Public Comment and Final Action
Because EPA believes the submitted rules fulfill all relevant requirements, we are proposing to fully approve them as described in section 110(k)(3) of the Act. We will accept comments from the public on this proposal for the next 30 days. Unless we receive convincing new information during the comment period, we intend to publish a final approval action that will incorporate these rules into the federally enforceable SIP and remove all sanctions and FIP obligations associated with our August 1, 2007 limited disapproval.

Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve State choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves State law as meeting Federal requirements and does not impose additional requirements beyond those imposed by State law. For that reason, this action:
Is not a ``significant regulatory action'' subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.); does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4); does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999); is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
