[EPA-R08-OAR-2012-0846; FRL-9751-5]


Approval and Promulgation of Air Quality Implementation Plans; 
Montana; Revisions to the Administrative Rules of Montana--Air Quality, 
Subchapter 7, Subchapter 16 and Subchapter 17

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve new rules and revisions as 
submitted by the State of Montana on September 23, 2011, as revisions 
to Montana's State Implementation Plan. Montana adopted these rules on 
December 2, 2005, and March 23, 2006. The new rules adopted on December 
2, 2005, became state-effective on January 1, 2006; the new rules and 
revisions adopted on March 23, 2006, became state-effective on April 7, 
2006. These new rules and revisions meet the requirements of the Clean 
Air Act and EPA's minor new source review regulations. The intended 
effect of this action is to propose to approve these rules as they are 
consistent with the Clean Air Act. This action is being taken under 
section 110 of the Clean Air Act.

II. What is being addressed in this proposed action?

    On September 23, 2011 the State of Montana submitted new rules and 
revisions to revise the Montana SIP. The submission contains new rules 
I-VI, codified as Administrative Rule of Montana (ARM) 17.8.1601, 
17.8.1602, 17.8.1603, 17.8.1604, 17.8.1605, and 17.8.1606, pertaining 
to the regulation of oil and gas well facilities. EPA is proposing to 
approve these new rules in this notice. The Montana Board of 
Environmental Review (Board) adopted these new rules to the existing 
SIP on December 2, 2005.
    This submission also contains new rules I-IX, codified as ARM 
17.8.1701, 17.8.1702, 17.8.1703, 17.8.1704, 17.8.1705,17.8.1710, 
17.8.1711, 17.8.1712 and 17.8.1713 pertaining to the regulation of oil 
and gas well facilities. EPA is proposing to approve these rule 
submissions in this action. The Board adopted these new rules to the 
existing SIP on March 23, 2006.
    This submission contains revisions to ARM 17.8.744 which were 
adopted on March 23, 2006. The proposed revisions to ARM 17.8.744 are a 
conforming change because of the addition of new rules.
    The proposed approval of the revised and new rules listed above 
would establish a registration system for oil and gas well facilities 
that presently require a Montana minor NSR air quality permit under the 
SIP regulations. The proposed new rules would allow the owner or 
operator of an oil or gas well facility to register with the Montana 
Department of Environmental Quality (MDEQ) in lieu of submitting a 
permit application and obtaining a permit to construct or modify the 
source before commencing construction or modification. Currently, with 
specific exemptions, the administrative rules adopted under the Montana 
Clean Air Act and approved by the EPA into the SIP, require the owner 
or operator of sources of air pollution to obtain a permit prior to 
construction or modification.
    Montana originally submitted these rules on October 16, 2006 and 
November 1, 2006, to EPA for inclusion into the SIP. EPA proposed to 
disapprove these submittals on January 6, 2011 (76 FR 758). EPA had 
several concerns with the Program, as was explained in 76 FR 758. In 
March of 2011, the State withdrew the October 16, 2006, and November 1, 
2006, submittals and, after several discussions between EPA and the 
State, Montana resubmitted the oil and gas rules on September 23, 2011. 
The State's September 2011 submittal included a revised CAA section 
110(l) demonstration and other supplemental data, which addressed the 
concerns we raised in our 76 FR 758 proposed action.

III. What Authorities Apply to EPA's Proposed Action

    Section 110(l) of the CAA states, ``[e]ach revision to an 
implementation plan submitted by a State under this Act shall be 
adopted by such State after reasonable notice and public hearing. The 
Administrator shall not approve a revision to a plan if the revision 
would interfere with any applicable requirement concerning attainment 
and reasonable further progress (as defined in section 171), or any 
other applicable requirement of this Act.''
    A demonstration is necessary to show that this revision will not 
interfere with attainment or maintenance of the NAAQS, including those 
for ozone, particulate matter, carbon monoxide, sulfur dioxide, lead, 
nitrogen oxides or any other requirement of the Act. Therefore, EPA 
will approve a SIP revision only after a state has demonstrated that 
such a revision will not interfere (``noninterference'') with 
attainment of the NAAQS, rate of progress, reasonable further progress 
or any other applicable requirement of the CAA.
    The CAA at section 110(a)(2)(C) requires states to include a minor 
NSR program in their SIP to regulate modifications and new construction 
of stationary sources within the area as necessary to assure the NAAQS 
are achieved. EPA's implementing regulations at 40 CFR 51.160-164 are 
intended to ensure that new source growth is consistent with 
maintenance of the NAAQS and 40 CFR 51.160(e) requires states to 
identify types and sizes of facilities which will be subject to review 
under their minor NSR program. For sources identified under 40 CFR 
51.160(e), section 51.160(a) requires that the SIP include legally 
enforceable procedures that enable a state or local agency to determine 
whether construction or modification of a facility, building, structure 
or installation, or combination of these will result in a violation of 
applicable portions of the control strategy; or interference with 
attainment or maintenance of a national standard in the state in which 
the proposed source (or modification) is located or in a neighboring 
state. Section 110(i) of the CAA specifically precludes states from 
changing the requirements of the SIP except through SIP revisions 
approved by EPA. SIP revisions will be approved by EPA only if they 
meet all

[[Page 67598]]

requirements of section 110 of the CAA and the implementing regulations 
at 40 CFR part 51. See CAA section 110(l); 40 CFR 51.104.
    EPA has also issued several guidance memoranda that explain the 
Agency's requirements for practicable enforceability for purposes of 
effectively limiting a source's potential to emit (See docket).
    EPA recognizes that, under the applicable federal regulations, 
states have broad discretion to determine the scope of their minor NSR 
programs as needed to attain and maintain the NAAQS. A state may tailor 
its minor NSR requirements as long as they are consistent with the 
requirements of 40 CFR part 51. States may also provide a rationale for 
why the rules are at least as stringent as the 40 CFR part 51 
requirements where the revisions are different from those in 40 CFR 
part 51.
    Since there are no ambient air quality standards for air toxics, 
the area's compliance with any applicable maximum achievable control 
technology (MACT) standards, as well as, any federal mobile source 
control requirements under CAA sections 112 or 202(l) would constitute 
an acceptable demonstration of noninterference for air toxics.
    Section 110(l) does not require a demonstration of noninterference 
for changes to federal requirements that are not included in the SIP. A 
revision to the SIP, however, cannot interfere with any federally 
mandated program such as a MACT standard (or related section 112 
requirements).

IV. EPA's Review and Proposed Action on SIP Revisions

    EPA is proposing to approve the new and revised rules as submitted 
by Montana on September 23, 2011, as identified above.
    As discussed above, any minor NSR SIP revision submittal must meet 
section 110(l) of the CAA. Section 110(l) of the Act indicates that EPA 
cannot approve a revision of a plan if the revision would interfere 
with any applicable requirement concerning attainment and reasonable 
further progress (as defined in Section 171), or any other applicable 
requirement of the Act. In a memo from Richard R. Long, Director, 
Region 8 Air and Radiation Program, to the Montana Board of 
Environmental Review on January 30, 2006 (see docket) we stated that 
MDEQ should provide an appropriate analysis showing that the proposed 
new rules will not impact the NAAQS or prevention of significant 
deterioration (PSD) increments. One of the concerns EPA expressed in 76 
FR 758 related to the cumulative effect of numerous registration 
sources. We recommended that MDEQ perform a screening cumulative impact 
analysis showing what effect oil and gas well facilities would have on 
the ozone, NO2, SO2 and PM NAAQS and PSD 
increments. MDEQ performed such an analysis. (See docket, demonstration 
of noninterference pages 1-42 and attachments 1-11.) MDEQ's analysis 
went back prior to 2006, when Montana began implementing the Oil and 
Gas Registration Program as a state-approved rule, and provided data on 
the amount of oil and gas registration applications received. 
Monitoring and modeling data for all NAAQS pollutants from 2006 to 
present shows that the Oil and Gas Registration Program has not 
interfered with attainment or maintenance of any NAAQS, PSD increment, 
or any other requirement of the Act. Therefore, EPA has sufficient 
information to determine that the proposed new and revised rules would 
not interfere with any applicable requirement concerning attainment and 
maintenance of the NAAQS, PSD increments, or any other requirement of 
the Act.
    EPA expressed concerns in 76 FR 758 that the new rules do not meet 
the requirements of CAA Section 110(a)(2)(A) and 40 CFR 51.160(a)(1), 
which require that SIP revision submittals be enforceable. The 
September 23, 1987, Memorandum from J. Craig Potter, Assistant 
Administrator for Air and Radiation, and Thomas L. Adams Jr., Assistant 
Administrator for Enforcement and Compliance Monitoring, entitled 
``Review of State Implementation Plans and Revisions for Enforceability 
and Legal Sufficiency'' provides EPA's guidance for interpreting this 
provision in the Act.
    EPA initially viewed the new rules as a stand-alone program, which 
was not subject to provisions in the other parts of ARM 17.8. As such, 
we were concerned that the new and revised rules did not set forth 
legally enforceable procedures that would enable the State or local 
agency to determine whether construction of a minor source facility 
would result in interference with attainment or maintenance of the 
NAAQS (40 CFR 51.160(a)) and that such procedures did not include a 
means by which the State or local agency to prevent construction of a 
minor source facility if it would result in interference with 
attainment or maintenance of the NAAQS (40 CFR51.160(b)). In 76 FR 758, 
EPA did not consider other requirements in ARM 17.8 as being applicable 
to the Program. However, after reviewing the State's 110(l) 
demonstration and the requirements in ARM 17.8, it is clear that the 
rules in ARM 17.8 subchapters 1-6 and portions of subchapter 7 apply to 
the State's new rules for oil and gas facilities registration. (See 
110(l) demonstration pages 2-9 and attachments 2 and 3 of the state's 
110(l) analysis.) These subchapters provide, for example, testing 
requirements, source testing protocol, malfunction procedures, 
enforcement procedures, and specific ambient air monitoring 
requirements for criteria pollutants. Therefore, the new and revised 
rules which we are proposing for approval in this notice are in 
compliance with CAA Section 110(a)(2)(A), 40 CFR 51.160(a) and 40 CFR 
51.160(b).
    EPA also had concerns that a source did not need to provide notice 
to the State before construction begins. The new and revised rules 
allow sources to operate and emit criteria pollutants up to 60 days 
before submitting a registration or permit application; therefore there 
is no requirement that the State be notified before construction 
begins. However, the new rules in ARM 17.8.16 contain numerous 
safeguards that facilities must operate under until the MDEQ approves 
the registration or permit application. These safeguards include: 
limiting production; limiting hours of operation and/or fuel 
consumption to ensure that the facility's potential to emit is below 
major source thresholds (17.8.1604); emission control requirements 
(17.8.1605); inspection and repair requirements (17.8.1608); and 
reporting and recordkeeping requirements (17.8.1609). Sources must also 
comply with requirements in ARM 17.8.1 (general requirements), ARM 
17.8.2 (ambient standards), and ARM 17.8.3 (emission standards), in 
addition to all other applicable requirements in ARM 17.8. Therefore, 
EPA concludes that the new and revised rules do not violate 40 CFR 
51.160(a) and 40 CFR 160(b).
    EPA also had concerns that the Program did not include the 
necessary monitoring, reporting and recordkeeping (MRR) requirements 
required for an oil and gas registration program to ensure 
accountability and provide a means to determine compliance. However, 
EPA did not consider the requirements of other subchapters of chapter 8 
when considering MRR requirements. As described in the State's 
submittal (110(l) demonstration, Table 1 (pages 3-15) and Table 2 
(pages 18-21), the MRR requirements in ARM 17.8.1 (General 
Requirements), ARM 17.8.2 (Ambient Air Quality), ARM 17.8.3 (Emission 
Standards) are all applicable to registered sources, in addition to the

[[Page 67599]]

MRR requirements in ARM 17.8.1605 and ARM 17.8.1713. Therefore, EPA 
proposes to find that the MRR requirements for a registered oil and gas 
facility are at least as stringent as what would be required for an oil 
and gas facility that would operate under a Montana Air Quality Permit 
(MAQP). The SIP approved MAQP rules contain no specific MRR 
requirements. Instead, a permitted facility is given MRR requirements 
through the actual permit. In existing MAQP regulations (ARM 17.8.7), 
the MRR requirements are specified in the facility permit pursuant to a 
case-by-case best available control technology analysis rather than 
uniform rule conditions.
    EPA also finds that the regulatory provisions in 40 CFR 51.160(c), 
40 CFR 51.160(d), 40 CFR 51.160(e) and 40 CFR 51.160(f), are met by the 
requirements in ARM 17.8.1703 (Registration Process and Information), 
ARM 17.8.1705 (Operating Requirements: Facility-Wide) and the 
requirements in ARM 17.8.1. The MDEQ issued a Notice of Public Hearing 
and allowed for public comment (see submittal, tabs 19 and 20), which 
meets the requirements in 40 CFR 51.161 (public availability of 
information). The requirements in 40 CFR 51.164 (stack height 
procedures) are met in ARM 17.8.4 (stack heights and dispersion 
techniques).
    EPA also expressed concerns in 76 FR 758 with new rule ARM 
17.8.1703(7), which provides that ``The owner or operator of a 
registration eligible facility for which a valid MAQP has been issued 
may register with the department and request a revocation of the 
MAQP.'' In 76 FR 758, EPA concluded this was a relaxation under CAA 
section 110(l), because it provides an exemption from SIP requirements 
not previously available to sources. This SIP relaxation would create a 
risk of interference with attainment and maintenance of the NAAQS and 
control strategy. EPA lacked sufficient information to determine that 
17.8.1703(7) would not interfere with attainment and maintenance of the 
NAAQS, PSD increment, or any other requirement of the Act.
    Montana issued approximately 30 MAQPs to oil and gas well 
facilities prior to implementing the oil and gas registration program. 
A comparison of MAQP requirements and registration requirements (see 
the state's110(l) analysis, pages 19-21) show comparable requirements.
    EPA also expressed concerns in 76 FR 758 with new rule ARM 
17.8.1712(1), which provides that, ``[l]eak detection methods may 
incorporate the use of sight, sound, or smell.'' After further review, 
we propose to find that this language is approvable because ARM 
17.8.1712(1) is similar to EPA regulatory requirements in 40 CFR part 
63, subpart BBBBBB and will not interfere with any applicable 
requirements of the Act. EPA notes that 40 CFR part 63, subpart BBBBBB 
provides similar leak detection methods using sight, sound, and smell. 
This regulation applies to area sources under the National Emission 
Standards for Hazardous Air Pollutants (NESHAPs) for Source Category: 
Gasoline Distribution Bulk Terminals, Bulk Plants, and Pipeline 
Facilities. EPA determined for this source category it was appropriate 
to allow leak detection methods using sight, sound, and smell.

V. Summary of Proposed Action

    EPA is proposing to approve revisions to ARM 17.8.744 and new rules 
I-VI, codified as ARM 17.8.1601, 17.8.1602, 17.8.1603, 17.8.1604, 
17.8.1605, and 17.8.1606, pertaining to the regulation of oil and gas 
well facilities, and new rules I-IX, codified as ARM 17.8.1701, 
17.8.1702, 17.8.1703, 17.8.1704, 17.8.1705,17.8.1710, 17.8.1711, 
17.8.1712 and 17.8.1713 pertaining to the regulation of oil and gas 
well facilities, as submitted by the State of Montana on September 23, 
2011.
    EPA is proposing to approve the new and revised rules as identified 
in this action and EPA is proposing approval based upon sufficient 
information to determine that the requested revision to add the new oil 
and gas registration program to the Montana SIP will not interfere with 
any applicable requirement concerning attainment and reasonable further 
progress as required by CAA Section 110(l), or any other requirement of 
the Act. The new and revised rules comply with section 110(a)(2)(C), 
which requires states to include a minor NSR program in their SIP to 
regulate modifications and new construction of stationary sources 
within the area as necessary to assure the NAAQS are achieved. EPA also 
finds the new and revised rules comply with 40 CFR 51.160-40 CFR 51.164 
and meet the requirements for appropriate MRR. EPA is also proposing to 
approve ARM 17.8.744 as these revisions are conforming changes to the 
addition of new rules.

VI. 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 CAA. Accordingly, 
this proposed 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,
