PM10 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 PM10 emissions. ICAPCD’s Regulation VIII consists of seven interrelated rules designed to limit emissions of PM10 from anthropogenic fugitive dust sources in Imperial County. PO 00000 Frm 00014 Adopted Fmt 4702 Sfmt 4702 Submitted 10/16/12 11/07/12 10/16/12 10/16/12 10/16/12 11/07/12 11/07/12 11/07/12 Rule 800, General Requirements for Control of Fine Particulate Matter, provides definitions, a compliance schedule, exemptions and other requirements generally applicable to all seven rules. It requires the U.S. Bureau of Land Management (BLM), U.S. Border Patrol (BP) and DPR to submit dust control plans (DCP) to mitigate fugitive dust from areas and/or activities under their control. Appendices A and B describe methods for determining compliance with opacity and surface stabilization requirements in Rules 801 through 806. Rule 801, Construction and Earthmoving Activities, establishes a E:\FR\FM\07JAP1.SGM 07JAP1 wreier-aviles on DSK7SPTVN1PROD with Federal Register / Vol. 78, No. 4 / Monday, January 7, 2013 / Proposed Rules 20% opacity limit and control requirements for construction and earthmoving activities. Affected sources must submit a DCP and comply with other portions of Regulation VIII regarding bulk materials, carry-out and track-out, and paved and unpaved roads. The rule exempts single family homes and waives the 20% opacity limit in winds over 25 mph under certain conditions. Rule 802, Bulk Materials, establishes a 20% opacity limit and other requirements to control dust from bulk material handling, storage, transport and hauling. Rule 803, Carry-Out and Track-Out, establishes requirements to prevent and clean-up mud and dirt transported onto paved roads from unpaved roads and areas. Rule 804, Open Areas, establishes a 20% opacity limit and requires land owners to prevent vehicular trespass and stabilize disturbed soil on open areas larger than 0.5 acres in urban areas, and larger than three acres in rural areas. Agricultural operations are exempted. Rule 805, Paved and Unpaved Roads, establishes a 20% opacity limit and control requirements for unpaved haul and access roads, canal roads and traffic areas that meet certain size or traffic thresholds. It also prohibits construction of new unpaved roads in certain circumstances. Single family residences and agricultural operations are exempted. Rule 806, Conservation Management Practices, requires agricultural operation sites greater than 40 acres to implement at least one conservation management practice (CMP) for each of several activities that often generate dust at agricultural operations. In addition, agricultural operation sites must prepare a CMP plan describing how they comply with Rule 806, and must make the CMP plan available to the ICAPCD upon request. EPA approved versions of all of these rules on July 8, 2010, but required revisions only to Rules 800, 804, 805 and 806. As a result, ICAPCD did not revise or resubmit Rules 801, 802 or 803. ICAPCD Rules 800, 804, 805 and 806 were revised primarily to: • Clarify and strengthen requirements for recreational off-highway vehicle (OHV) activity; • Demonstrate BACM; • Clarify the definition of disturbed surface area and conservation management practice (CMP); • Verify responsibility for stabilizing public unpaved roads in the county by VerDate Mar<15>2010 15:15 Jan 04, 2013 Jkt 229001 the Imperial County Department of Public Works; • Include opacity limits and stabilization requirements for hightraffic unpaved agricultural roads and traffic areas; • Add CMP requirements for cropland-others, windblown dust control and agricultural tilling and harvesting; and • Remove the exemption for border patrol roads. EPA’s technical support document (TSD) has more information about these rules. II. EPA’s Evaluation and Action A. 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 PM10 nonattainment areas, and Best Available Control Measures (BACM), including Best Available Control Technology (BACT), in serious PM10 nonattainment areas (see CAA sections 189(a)(1) and 189(b)(1)). The ICAPCD regulates a PM10 nonattainment area classified as serious (see 40 CFR part 81), so Rules 800, 804, 805 and 806 must implement BACM. Guidance and policy documents that we use to evaluate enforceability and BACM requirements consistently include the following: 1. ‘‘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. 2. ‘‘Guidance Document for Correcting Common VOC & Other Rule Deficiencies,’’ EPA Region 9, August 21, 2001 (the Little Bluebook). 3. ‘‘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). 4. ‘‘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). 5. ‘‘PM–10 Guideline Document,’’ EPA 452/R–93–008, April 1993. 6. ‘‘Fugitive Dust Background Document and Technical Information PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 923 Document for Best Available Control Measures,’’ EPA 450/2–92–004, September 1992. B. Do the rules meet the evaluation criteria? We believe these rules are consistent with the relevant policy and guidance regarding enforceability, BACM, and SIP relaxations. The revised rules adequately address all deficiencies identified in our July 8, 2010 (75 FR 39366) final limited disapproval of a previous version of these rules. Rules 801, 802, and 803 were approved in the July 8, 2010 rulemaking as meeting BACM requirements and are not affected by this action. The TSD has more information on our evaluation. C. Reasonable Control for Exceptional Events EPA’s preliminary view is that the Regulation VIII rules as revised in October 2012 constitute reasonable control of the sources covered by Regulation VIII for the purpose of evaluating whether an exceedance of the PM10 NAAQS is an exceptional event pursuant to the exceptional events rule, including reasonable and appropriate control measures on significant contributing anthropogenic sources. This statement does not extend to exceedances of NAAQS other than the PM10 NAAQS, or to events that differ significantly in terms of meteorology, sources, or conditions from the events that were at issue in EPA’s July 2010 final action and associated litigation. EPA is not making any determinations at this time with respect to any specific PM10 exceedances. D. EPA Recommendations To Further Improve the Rules The TSD describes additional rule revisions that we recommend for the next time the local agency modifies the rules but are not currently the basis for rule disapproval. E. 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. If finalized as proposed, this action would permanently terminate all sanctions and FIP implications associated with the July 8, 2010 final action.

Statutory and Executive Order Reviews costs on tribal governments or preempt tribal law. 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 proposed action merely proposes to approve State law as meeting Federal requirements and does not impose additional requirements beyond those imposed by State law. For that reason, this proposed 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 disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this proposed action 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 List of Subjects in 40 CFR Part 52 Environmental protection, Air pollution control, Intergovernmental relations, Particulate matter, Reporting and recordkeeping requirements.

ACTION: Proposed rule. AGENCY: EPA is proposing to approve the Limited Maintenance Plan (LMP) submitted by the State of Alaska on September 29, 2010, for the Eagle River nonattainment area (Eagle River NAA) and the State’s request to redesignate the area to attainment for the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10). EPA is proposing to approve the State’s request because it meets Clean Air Act (CAA) requirements for redesignation. EPA has also published, at the same time, a direct final rule of the same title because EPA views this as a noncontroversial SIP revision and anticipates no adverse comments. Any parties interested in commenting on this action should do so at this time.

----------------------------------------------------------------------------------------------------------------

    On November 21, 2012, EPA determined that the submittal for ICPACD 
Rules 800, 804, 805 and 806 met the completeness criteria in 40 CFR 
Part 51 Appendix V, which must be met before formal EPA review.

B. Are there other versions of these rules?

    We finalized a limited approval and limited disapproval of an 
earlier version of the submitted rules on July 8, 2010 (75 FR 39366). 
That action incorporated Rules 800, 804, 805 and 806 into the 
California SIP, including those provisions identified as deficient.

C. What is the purpose of the submitted rule revisions?

    PM10 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 
PM10 emissions. ICAPCD's Regulation VIII consists of seven 
interrelated rules designed to limit emissions of PM10 from 
anthropogenic fugitive dust sources in Imperial County.
    Rule 800, General Requirements for Control of Fine Particulate 
Matter, provides definitions, a compliance schedule, exemptions and 
other requirements generally applicable to all seven rules. It requires 
the U.S. Bureau of Land Management (BLM), U.S. Border Patrol (BP) and 
DPR to submit dust control plans (DCP) to mitigate fugitive dust from 
areas and/or activities under their control. Appendices A and B 
describe methods for determining compliance with opacity and surface 
stabilization requirements in Rules 801 through 806.
    Rule 801, Construction and Earthmoving Activities, establishes a

[[Page 923]]

20% opacity limit and control requirements for construction and 
earthmoving activities. Affected sources must submit a DCP and comply 
with other portions of Regulation VIII regarding bulk materials, carry-
out and track-out, and paved and unpaved roads. The rule exempts single 
family homes and waives the 20% opacity limit in winds over 25 mph 
under certain conditions.
    Rule 802, Bulk Materials, establishes a 20% opacity limit and other 
requirements to control dust from bulk material handling, storage, 
transport and hauling.
    Rule 803, Carry-Out and Track-Out, establishes requirements to 
prevent and clean-up mud and dirt transported onto paved roads from 
unpaved roads and areas.
    Rule 804, Open Areas, establishes a 20% opacity limit and requires 
land owners to prevent vehicular trespass and stabilize disturbed soil 
on open areas larger than 0.5 acres in urban areas, and larger than 
three acres in rural areas. Agricultural operations are exempted.
    Rule 805, Paved and Unpaved Roads, establishes a 20% opacity limit 
and control requirements for unpaved haul and access roads, canal roads 
and traffic areas that meet certain size or traffic thresholds. It also 
prohibits construction of new unpaved roads in certain circumstances. 
Single family residences and agricultural operations are exempted.
    Rule 806, Conservation Management Practices, requires agricultural 
operation sites greater than 40 acres to implement at least one 
conservation management practice (CMP) for each of several activities 
that often generate dust at agricultural operations. In addition, 
agricultural operation sites must prepare a CMP plan describing how 
they comply with Rule 806, and must make the CMP plan available to the 
ICAPCD upon request.
    EPA approved versions of all of these rules on July 8, 2010, but 
required revisions only to Rules 800, 804, 805 and 806. As a result, 
ICAPCD did not revise or resubmit Rules 801, 802 or 803.
    ICAPCD Rules 800, 804, 805 and 806 were revised primarily to:
     Clarify and strengthen requirements for recreational off-
highway vehicle (OHV) activity;
     Demonstrate BACM;
     Clarify the definition of disturbed surface area and 
conservation management practice (CMP);
     Verify responsibility for stabilizing public unpaved roads 
in the county by the Imperial County Department of Public Works;
     Include opacity limits and stabilization requirements for 
high-traffic unpaved agricultural roads and traffic areas;
     Add CMP requirements for cropland-others, windblown dust 
control and agricultural tilling and harvesting; and
     Remove the exemption for border patrol roads.
    EPA's technical support document (TSD) has more information about 
these rules.

II. EPA's Evaluation and Action

A. 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 PM10 nonattainment areas, and 
Best Available Control Measures (BACM), including Best Available 
Control Technology (BACT), in serious PM10 nonattainment 
areas (see CAA sections 189(a)(1) and 189(b)(1)). The ICAPCD regulates 
a PM10 nonattainment area classified as serious (see 40 CFR 
part 81), so Rules 800, 804, 805 and 806 must implement BACM.
    Guidance and policy documents that we use to evaluate 
enforceability and BACM requirements consistently include the 
following:
    1. ``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.
    2. ``Guidance Document for Correcting Common VOC & Other Rule 
Deficiencies,'' EPA Region 9, August 21, 2001 (the Little Bluebook).
    3. ``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).
    4. ``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).
    5. ``PM-10 Guideline Document,'' EPA 452/R-93-008, April 1993.
    6. ``Fugitive Dust Background Document and Technical Information 
Document for Best Available Control Measures,'' EPA 450/2-92-004, 
September 1992.

B. Do the rules meet the evaluation criteria?

    We believe these rules are consistent with the relevant policy and 
guidance regarding enforceability, BACM, and SIP relaxations. The 
revised rules adequately address all deficiencies identified in our 
July 8, 2010 (75 FR 39366) final limited disapproval of a previous 
version of these rules. Rules 801, 802, and 803 were approved in the 
July 8, 2010 rulemaking as meeting BACM requirements and are not 
affected by this action. The TSD has more information on our 
evaluation.

C. Reasonable Control for Exceptional Events

    EPA's preliminary view is that the Regulation VIII rules as revised 
in October 2012 constitute reasonable control of the sources covered by 
Regulation VIII for the purpose of evaluating whether an exceedance of 
the PM10 NAAQS is an exceptional event pursuant to the 
exceptional events rule, including reasonable and appropriate control 
measures on significant contributing anthropogenic sources. This 
statement does not extend to exceedances of NAAQS other than the 
PM10 NAAQS, or to events that differ significantly in terms 
of meteorology, sources, or conditions from the events that were at 
issue in EPA's July 2010 final action and associated litigation. EPA is 
not making any determinations at this time with respect to any specific 
PM10 exceedances.

D. EPA Recommendations To Further Improve the Rules

    The TSD describes additional rule revisions that we recommend for 
the next time the local agency modifies the rules but are not currently 
the basis for rule disapproval.

E. 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. If finalized as proposed, this action would 
permanently terminate all sanctions and FIP implications associated 
with the July 8, 2010 final action.

III. 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 proposed action merely proposes to approve State law 
as meeting Federal requirements and does not impose additional 
requirements beyond those imposed by State law. For that reason, this 
proposed 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 disproportionate human health or environmental effects with 
practical, appropriate, and legally permissible methods under Executive 
Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this proposed action 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.
