routine amendments are necessary to keep them operationally current. It, therefore, (1) is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a Regulatory Evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, would not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This proposed rulemaking is promulgated under the authority described in Subtitle VII, Part, A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This proposed regulation is within the scope of that authority as it would establish Class E airspace at Umatilla Municipal Airport, Umatilla,
FL.

This proposal will be subject to an environmental analysis in accordance with FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures’’ prior to any FAA final regulatory action.

**Review of New Sources and Modifications in Indian Country** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The EPA is proposing three changes to the New Source Review (NSR) program for minor sources and minor modifications at major sources in Indian country, which we refer to as the ‘‘Tribal minor NSR program.’’ First, we propose to expand the list of emissions units and activities that are exempt from the Tribal minor NSR program by adding several types of low-emitting units and activities. Second, we propose to more clearly define the term ‘‘commence construction’’ and add the term ‘‘begin construction’’ to better reflect the regulatory requirements associated with construction activities. We believe both of these proposed changes would simplify the program, resulting in less burdensome implementation without detriment to air quality in Indian country. Lastly, we are reconsidering the advance notification period for relocation of a true minor source in response to a petition received on the final Tribal NSR rule from the American Petroleum Institute, the Independent Petroleum Association of America and America’s Natural Gas Alliance.

II. Purpose

The purpose of this rule is to propose and seek comment on three revisions to the Tribal minor NSR rule 1 that will streamline implementation by adding more exempted units/activities, clarifying language related to construction and relocation of true minor sources. Specifically, we are proposing to add seven categories of units/activities that will be listed as exempt from the Tribal minor NSR rule because their emissions are deemed insignificant. Listing these categories explicitly will mean that many applicants and reviewing authorities will not need to calculate potential emissions for activities that can be deemed insignificant. In the preamble to the Tribal minor NSR rule, we committed to considering the addition


### 33269 Federal Register / Vol. 78, No. 107 / Tuesday, June 4, 2013 / Proposed Rules

2 The Tribal Authority Rule is comprised of Subpart A of 40 CFR part 49, which is titled ‘‘Indian Country: Air Quality Planning and Management’’.

3 The PSD program is a preconstruction permitting program that applies to new major stationary sources (major sources) and major modifications in areas attaining the NAAQS, including attainment areas in Indian country.

4 Title V of the Act requires all new and existing major sources in the United States to obtain and comply with an operating permit that brings together all of the source’s applicable requirements under the Act. All states, numerous local areas and one tribe have approved title V permitting programs under the regulations at 40 CFR part 70. The EPA implements the part 71 federal program in Indian country and other areas that are not covered by an approved part 70 program. Currently, one tribe has been delegated authority to assist the EPA with administration of the federal part 71 program. 5 40 CFR 49.152 defines ‘‘synthetic minor source’’ as a source that otherwise has the potential to emit regulated NSR pollutants in amounts that are at or above those for major sources in section 49.167, section 52.21 or section 71.2 of chapter 40, as applicable, but that has taken a restriction so that its PTE is less than such amounts for major sources. Such restrictions must be enforceable as a practical

matter.

6 40 CFR 49.152 defines ‘‘true minor source’’ as a source, not including the exempt emissions units and activities listed in section 49.153(c), that emits or has the potential to emit regulated NSR pollutants in amounts that are less than the major source thresholds in section 49.167 or section 52.21 of Chapter 40, as applicable, but equal to or greater than the minor NSR thresholds in section 49.153, without the need to take an enforceable restriction to reduce its PTE to such levels. of exempt units/activities to the list in that final rule, as requested by commenters. This proposed rule fulfills that commitment.

In the Tribal minor NSR rule, the term ‘‘commence construction’’ is used in two different contexts, i.e., the provisions governing construction prohibition, and also the provisions specifying that construction must occur within 18 months of the permit effective date. In this proposal, we are clarifying this distinction by proposing two different terms for those situations— ‘‘begin construction’’ and ‘‘commence construction.’’ Accordingly, we are also proposing to replace ‘‘commence construction’’ with ‘‘begin construction,’’ in certain sections of the regulatory text for consistency. The third proposed revision is reconsideration of the 30-day advance notice requirement for a true minor source prior to relocation. This is in response to a request on the final rule from the American Petroleum Institute, the Independent Petroleum Association of America and America’s Natural Gas Alliance.

III. Background

A. What are the general requirements of the minor NSR program?

Section 110(a)(2)(C) of the Clean Air Act (Act) requires that every state implementation plan (SIP) include a program to regulate the construction and modification of stationary sources, including a permit program as required in parts C and D of title I of the Act, to ensure attainment and maintenance of the National Ambient Air Quality Standards (NAAQS). The permitting program for minor sources is addressed by section 110(a)(2)(C) of the Act, which we commonly refer to as the minor NSR program. A minor source means a source that has a potential to emit (PTE) lower than the major NSR applicability threshold for a particular pollutant as defined in the applicable nonattainment major NSR program or Prevention of Significant Deterioration (PSD) program.

States must develop minor NSR programs to attain and maintain the NAAQS and the federal requirements for state minor NSR programs are outlined in 40 CFR 51.160 through 51.164. These federal requirements for minor NSR programs are considerably less prescriptive than those for major sources and, as a result, there is a larger variation of requirements across the state minor NSR programs.

Furthermore, sections 301(a) and 301(d)(4) of the Act, as implemented through the Tribal Authority Rule, 2 provide the EPA with a broad degree of discretion in developing a program to regulate new and modified minor sources in Indian country.

B. What is the Tribal NSR rule?

The ‘‘Review of New Sources and Modifications in Indian country’’ ( i.e., Tribal NSR rule) final rule was published in the Federal Register on July 1, 2011 (76 FR 38748), pursuant to sections 301(a) and (d) of the Act. This rule established a federal implementation plan (FIP) for Indian country that includes two NSR regulations for the protection of air resources in Indian country. These two new NSR regulations work together with the pre-existing PSD program at 40 CFR

52.21 3 and the title V operating permits program at 40 CFR part 71 4 to provide a comprehensive permitting program for Indian country to ensure that air quality in Indian country will be protected in the manner intended by the Act.

One regulation created by the Tribal NSR rule, which we call the ‘‘Tribal minor NSR rule,’’ applies to new and modified minor stationary sources (minor sources) and to minor modifications at existing major stationary sources (major sources) throughout Indian country where there is no EPA-approved plan in place. The second regulation, which we refer to as the ‘‘tribal nonattainment major NSR rule,’’ applies to new and modified major sources in areas of Indian country that are designated as not attaining the NAAQS (nonattainment areas). Through these two regulations, the Tribal NSR rule ensures that Indian country will be protected in the manner intended by the Act by establishing a preconstruction permitting program for new or modified minor sources, minor modifications at major sources, and new major sources and major modifications in
nonattainment areas.

The Tribal minor NSR rule applies to new and modified minor sources and to minor modifications at major sources. New minor sources with a PTE equal to or greater than the minor NSR thresholds, or modifications at existing minor sources with allowable emissions increases equal to or greater than the minor NSR thresholds, must apply for and obtain a minor NSR permit prior to beginning construction of the new source or modification.

Under the nonattainment major NSR rule, affected sources are required to comply with the provisions of 40 CFR part 51, Appendix S. In recent years, Appendix S has primarily been used as a transitional rule for nonattainment major NSR permitting in nonattainment areas for which state agencies do not have an approved nonattainment major NSR program for a particular pollutant in their SIPs. Sources subject to the nonattainment major NSR rule must meet requirements for Lowest Achievable Emissions Rate (LAER) control technology, emissions offsets and compliance certification.

The effective date of the minor Tribal NSR rule was August 30, 2001. To facilitate the effective implementation of the Tribal minor NSR program, some components of the rule were phased in. Generally, the applicability of the preconstruction permitting rules to new synthetic minor sources 5 began on the rule’s effective date, August 30, 2011; for new or modified true minor

sources, 6 the rules apply beginning the earlier of September 2, 2014, or 6 months after the publication of a final general permit for that source category in the Federal Register (40 CFR 49.151(c)(1)(iii)(B)). In addition, existing true minor sources in Indian country were required to register with their reviewing authority by March 1, 2013.
C. What is the status of the NSR air quality program in Indian Country?

No tribe is currently administering an EPA-approved PSD program. Therefore, the EPA has been implementing a FIP to issue PSD permits for major sources in


### 33270 Federal Register / Vol. 78, No. 107 / Tuesday, June 4, 2013 / Proposed Rules

7 This review included minor NSR permitting regulations from the State of Colorado and the South Coast Air Management District since these states/agencies were specifically cited by

commenters. See Docket ID No. EPA–HQ–OAR– 2003–0076 for the listing of state regulations reviewed. 8 The FARR is a FIP that applies to air pollution sources on Indian reservations in Idaho, Oregon and attainment areas of Indian country (40 CFR 52.21). There are also no tribescurrently administering an EPAapproved nonattainment major NSR program, so EPA is the reviewing authority under a FIP (40 CFR 49.166 through 49.175). Only a few tribes are administering EPA-approved minor NSR programs. Accordingly, EPA administers minor NSR programs in most areas of Indian country under a FIP (40 CFR 49.151 through 49.165).

Sections 301(d) and 110(o) of the Act provide eligible tribes the opportunity to develop their own tribal programs and we encourage eligible tribes to develop their own minor and nonattainment major NSR programs, as well as a PSD major source program, for incorporation into tribal implementation plans (TIPs). Tribes may use the tribal NSR FIP program as a model if they choose to develop their own TIPs and seek our approval.
IV. Proposed Revisions to the Tribal Minor NSR Rule

This section discusses the proposed revisions to the Tribal minor NSR rule and our rationale for proposing those changes. We solicit public comment on the changes being proposed and will consider those comments in developing the final rule.

A. Emissions Units and Activities Exempted From the Tribal Minor NSR Rule

In the Tribal minor NSR rule promulgated on July 1, 2011 (76 FR 38792), we exempted seven emissions units/activities from the Tribal minor NSR permitting program pursuant to 40 CFR 49.153(c) because their potential emissions are insignificant. Listing units/activities with trivial emissions as exempt saves permitting resources because it eliminates the need for applicants or permitting agencies to calculate the potential emissions to verify they do not exceed minor source permitting thresholds. In the preamble to that rule, we referred to comments received regarding our originally proposed list of exempt units/activities (i.e., the August 21, 2006, proposed rule) and we committed to consider additional units/activities for exemption from minor NSR permitting, and to propose and seek comment on such revisions through a separate rulemaking (76 FR 38759). This proposal fulfills that
commitment.

In the Tribal minor NSR rule proposed on August 21, 2006, we listed ten categories of units/activities for exemption from minor NSR permitting. We received eleven comment letters concerning the list of exempted units/ activities. Many commenters said the list should be more extensive, similar to state source exemption lists from minor NSR permitting. The majority of those commenters stated that a longer list of exemptions would ‘‘level the playing field’’ between sources located in Indian country, and those on adjacent lands subject to EPA-approved state NSR programs, by treating them more equitably regarding the types of minor sources that would be exempt from minor NSR permitting. We considered this information in determining whether to modify the exemptions list in the existing Tribal minor NSR rule and also reviewed unit/activity-exemption lists from many states that also contain Indian country. 7

We noted several things from our review of state minor source rules that apply outside Indian country. One observation is that some state regulations do not provide any minimum NSR pollutant emission thresholds below which sources are exempt from state minor NSR permitting requirements. In those cases, any new source or activity not specifically exempted by its state rule is potentially subject to its minor NSR permitting program. By contrast, the existing Tribal minor NSR rule already contains minor NSR thresholds, thereby providing a mechanism for sources to avoid being subject to minor source permitting without being specifically listed for exemption. A second observation is that many state minor NSR permitting regulations contain language specifying that a permitting exemption for a specific source-type does not apply if that source is subject to either the requirements of 40 CFR part 60 NSPS, Part 61 National Emission Standards for Hazardous Air Pollutants (NESHAP), or Part 63 MACT (New Source Performance Standards (NSPS), NESHAP and MACT programs). By including such language in their minor source regulations, the states have attempted to address any sources that may have significant emissions and the potential to negatively impact ambient air quality. This approach ensures that sources that might otherwise be exempt from permitting are subject to minor NSR permitting. Since the Tribal minor NSR rule does not contain similar language, we have chosen fewer categories than some states, but morethan others, in the number of sourcetypes exempted. We have taken this approach to limit exemptions to fewer source types since, without the ‘‘backstop’’ of the permitting obligation tied to sources subject to NSPS, NESHAP or MACT programs, we might inadvertently exempt non-trivial sources, potentially degrading air quality in Indian country.

As a result, we considered a variety of source types and are proposing to add units/activities to the exemptions list that are expected: (1) to have inherent emissions significantly less than the minor NSR thresholds in 40 CFR 49.153, and (2) are expected to be very common and sited at many sources such that an exemption from needing to calculate PTE to determine applicability would reduce the burden on these sources. In essence, we are seeking to strike a balance between ensuring that the permitting of minor emission sources is consistent with the requirements of the Act, and exempting source categories where the permitting process adds administrative burden but offers no significant environmental benefit. We believe the sources we propose to add to the exempted list have emissions below the relevant applicability thresholds due to their operational

nature. See additional discussion below in the section titled, ‘‘Information Obtained from Source Registration under Federal Air Rule for Indian Reservations (FARR).’’

We note that for determining applicability, a source’s emissions are based on PTE and are determined on a source-wide basis and not an individual unit basis. For this reason, when considering potential units/activities for addition to the exemptions list, which are excluded from a source’s PTE calculation, we were mindful of the possibility that multiple individual units/activities, while perhaps individually below the Tribal minor NSR permitting thresholds, could collectively exceed those thresholds ( e.g., two non-emergency, stationary engines at the same facility). For that reason we limited the number exempt units/activities to minimize inadvertently exempting units/activities that would exceed minor source permitting thresholds based on combined potential emissions with other exempted units/activities at the

source.

Several of the units/activities we are proposing to add to the exemptions list are currently exempted under the FARR’s air pollution source registration program under 40 CFR 49.138. 8 We

10. believe that adding these same units/ activities to the Tribal minor NSR rule’s exemption list would provide consistency in implementing rules affecting similar sources in Indian country. We also believe it is appropriate to include exemptions contained in the FARR because that list was developed with the intent of exempting both (1) the units/activities with de minimis levels of emissions, and (2) those for which a registration requirement would create an unreasonable burden. We are proposing to include most units/activities from the FARR that we believe have de minimis
emissions.

Additional Units/Activities for Exemption

Based on our review of state lists, and anticipation of lower source emissions, we are proposing to add the following units/activities to the exempt units/ activities list:

• Emergency generators, designed solely for the purpose of providing electrical power during power outages: in nonattainment areas, the total maximum manufacturer’s site-rated horsepower of all units shall be below 500; in attainment areas, the total maximum manufacturer’s site-rated horsepower of all units shall be below 1,000. The horsepower thresholds were established to ensure that minor NSR nitrogen oxide (NO X) thresholds are not exceeded using the maximum annual run-time of 500 hours per year, based on EPA’s PTE guidance.

• Stationary internal combustion engines with a manufacturer’s site-rated horsepower of less than 50.

• Furnaces or boilers used for space heating exclusively using gaseous fuel with a total maximum heat input (i.e., from all units combined) of 10 million British thermal units per hour (MMBtu/ hr) (5 MMBtu/hr in nonattainment areas) or less. Based on our review of state regulations, and a determination that the NO X emissions threshold of 5 tons/year would not be exceeded, we are proposing a maximum fuel usage rate of 10 MMBtu/hr (5 MMBtu/hr in nonattainment areas) for these units.

We are proposing to add the following units/activities to the list of sources that are exempt from minor NSR permitting:

• Single family residences and residential buildings with four or fewer dwelling units. This would typically include units such as furnaces and hot water heaters.

• Air conditioning units used for human comfort that do not exhaust air pollutants to the atmosphere from any manufacturing or other industrial

processes.

• Forestry and silvicultural activities. The FARR defines these as activities associated with regeneration, growing, and harvesting of trees and timber including, but not limited to, preparing sites for new stands of trees to be either planted or allowed to regenerate through natural means, road construction and road maintenance, fertilization, logging operations, and forest management techniques employed to enhance the growth of stands of trees or timber. They do not include milling operations.

Exemptions for air conditioning units and heating units for comfort were originally proposed in the August 21, 2006, Tribal minor NSR proposed rule. We did not finalize those exemptions, however, because we were uncertain at that time how the upcoming greenhouse gas (GHG) regulations, then under development, would affect GHG permitting thresholds and thus how the outcome of that process might impact those activities. We have now completed the GHG Tailoring Rule Step 3 rulemaking and not lowered GHG permitting applicability thresholds. Therefore, we believe these units will not trigger GHG permitting requirements and we are proposing to add the exemption for air conditioning units (the non-manufacturing/industrial process type) and certain units used for space heating to the list of exempted units and activities in the Tribal minor NSR rule. If the EPA lowers GHG permitting thresholds in the future, we will reevaluate whether these exemptions continue to be appropriate.

Revision to the Existing Exempted Units/Activities List

Lastly, in addition to the proposed additions to the exempted units/ activities listed above, we are proposing to revise the existing exemption criteria for food preparation activities currently specified in 40 CFR 49.153(c)(3) such that the current exemption, limited to noncommercial cooking of food, will be expanded to include certain types of commercial operations. We are proposing the same definition that is used in the FARR, i.e., an exemption for the cooking of food other than wholesale businesses that both cook and sell cooked food. This proposed revision will broaden the current exemption to fast food vendors and stand alone restaurants and is being added because we believe these sources have de
minimis emissions. Information Obtained From Source Registration Under FARR

The FARR, under 40 CFR 49.138, requires sources on the covered Indian reservations, unless otherwise exempt, to register their facility with EPA Region 10 ( i.e., the reviewing authority) each year. As part of that registration process, the source must submit an estimate of its actual emissions (for criteria and other specified pollutants). There are 39 Indian reservations located in Idaho, Oregon and Washington covered under the FARR. While these 39 reservations represent only a portion of Indian country nationwide, we believe the source-registration information collected by EPA Region 10 is useful tohelp inform us regarding the sourcetypes potentially subject to minor source permitting (note: the FARR requires both minor and major sources of NSR pollutants to register).

For 2011, the most recent registration year completed under the FARR, a total of 153 sources located within applicable Indian reservations have registered. Nearly all of the registered sources perform activities that are potentially covered under one or more EPA air rules (i.e., a MACT or NSPS rule) when relevant emissions, or other thresholds, are met (i.e., they are industrial sources). This information suggests that the list of exemptions in the FARR is effective at screening out and reducing unnecessary administrative burden on the types of small emission sources we intend to exempt from permitting through the proposed revisions to the list in the Tribal minor NSR rule and indicates that a relatively short list of exempt units/activities can fulfill our objective. Similarly, under the Tribal minor NSR rule, units/activities that are not exempt from minor NSR permitting based on the exemptions list can still qualify for an exemption if their estimated potential emissions are below the thresholds contained in 40 CFR

49.153.
B. Defining Construction-Related Activities for Permitting Purposes

Under the Tribal minor NSR permitting program, the point at which construction begins is critical in two instances: 1) For new or modified sources that have not obtained a minor NSR permit, construction is prohibited until a permit is issued; and 2) For new or modified sources that have received a minor NSR permit, construction must begin within 18 months of permit issuance for the permit to remain valid.

In the existing Tribal minor NSR rule, the term ‘‘commence construction’’ is used for both situations described


### 33272 Federal Register / Vol. 78, No. 107 / Tuesday, June 4, 2013 / Proposed Rules

9 July 1, 2011 Federal Register , 76 FR 38783. 10 The definition of ‘‘construction’’ under 40 CFR 52.21(b) for major sources carries with it a lengthy history of implementing that term under the major source program. The types of sources regulated under the major source program are predominantly much more complex in nature than those regulated under the Tribal minor NSR rule. Therefore, it would be inconsistent with our intent to simplify implementation for minor sources or minor modifications, to refer to the term used in the major

source program. above, i.e., where construction is prohibited and also where construction must occur within 18 months. In this proposal, we are intend to clarify two different terms that are relevant for these two different situations as follows:

1. Construction Prohibited Prior to Permit Issuance—Definition of ‘‘Begin
Construction.’’

The term ‘‘commence construction’’ is used in certain sections of the existing Tribal minor NSR rule to indicate that construction is prohibited prior to obtaining a permit. To make this provision of the rule consistent with a similar provision of the major NSR rule, we are proposing to replace the term ‘‘commence construction’’ with ‘‘begin construction’’ in those cases where the rule specifies that a permit is required before constructing or modifying a

source.

One section of the rule where we are proposing to change ‘‘commence construction’’ to ‘‘begin construction’’ is 40 CFR 49.151(c)(1)(iii)(B). In addition to this proposed change, we believe the regulatory text in this section could be clearer in stating our intent to delay the implementation date of the minor NSR permitting program for true minor sources, due to resource constraints, until September 2, 2014 9 . Therefore, we are proposing to revise this section. We believe that by moving the date at which applicability is triggered to the beginning of this section it is clearer that true minor sources are not required to obtain a permit unless they begin construction on or after the date that is the earlier of: six months after a final general permit for that specific source category is published in the Federal Register , or September 2, 2014.

We are also proposing to provide a specific definition for ‘‘begin construction.’’ The proposed definition for ‘‘begin construction’’ is based on the definition of ‘‘begin actual construction’’ in 40 CFR 52.21 with some modifications. One proposed modification is a provision clarifying that certain preparatory activities are not considered to be construction activities, and therefore can be performed prior to receiving a permit. The following proposed list of activities is generally consistent with what wehave historically allowed in our sitespecific determinations, related to construction activities, under the major NSR program: engineering and design planning, geotechnical investigation (surface and subsurface explorations), clearing, surveying, ordering of equipment and materials, storing of equipment or setting up temporary trailers to house construction management or staff and contractor personnel. We believe this listing of activities will reduce the uncertainty of whether an activity constitutes ‘‘begin construction’’ under the Tribal minor NSR program.

2. Construction Necessary after Permit Issuance—Definition of ‘‘Commence
Construction.’’

The existing Tribal minor NSR rule does not define the term ‘‘commence construction.’’ Currently, because that term is not defined in the Tribal minor NSR rule, the definition(s) under 40 CFR 52.21 (i.e., the PSD program) applies. However, while 40 CFR 52.21(b) defines ‘‘construction 10 ’’ and ‘‘commence’’ it does not expressly define the term ‘‘commence construction.’’ Therefore, we are proposing a distinct definition under the Tribal minor NSR rule for ‘‘commence construction’’ that will assist in implementing the minor NSR provisions.

The definition being proposed for ‘‘commence construction’’ for purposes of Tribal minor NSR primarily uses terminology from the definition of ‘‘commence’’ under 40 CFR 52.21 that applies to major source NSR. However, similar to the proposed definition of ‘‘begin construction,’’ this proposed definition also includes the following language to clarify the preparatory activities that are not considered to be within the scope of commencing construction: engineering and design planning, geotechnical investigation (surface and subsurface explorations), clearing, surveying, ordering of equipment and materials, storing of equipment or setting up temporary trailers to house construction management or staff and contractor personnel. The list of activities considered to be preparatory, and therefore not considered to be commencing construction, is included to clarify that these activities do not count when determining whether the source has commenced construction by a specified date. In contrast, the activities that are substantial, and therefore do count toward determining that a source has commenced construction, are activities such as: installation of building supports and foundations, paving, laying of underground pipe work, construction of permanent storage structures, and activities of a similar nature.
C. Advance Notification Time Period for Relocation of True Minor Sources

The Tribal minor NSR rule includes a registration program for true minor sources. This program was developed to improve our understanding of the types, and number, of minor sources located in Indian country. This program requires, under 40 CFR 49.160(c), the owner/ operator of true minor sources to register their source with their reviewing authority. The information submitted as part of that registration includes the source’s location. If an owner/operator plans to move the source to another location, that owner/ operator is required under 40 CFR 49.160(d)(1) to submit a notice of relocation no later than 30 days prior to relocating. Among other reasons, this requirement allows us to maintain the accuracy of our minor source inventory in Indian country.

We received a letter on November 4, 2011, from the American Petroleum Institute, the Independent Petroleum Association of America and America’s Natural Gas Alliance (collectively, the Petitioners) requesting that we reconsider the 30-day advance notice provision for registered sources prior to relocation. The EPA responded to that request in a letter dated December 19, 2012, from then EPA Administrator Lisa Jackson to the Petitioners, where we agreed to reconsider the 30-day notice requirement. We stated in that December 19, 2012, letter that we would publish a Federal Register notice to address the specific issues for which we granted reconsideration and we are addressing the 30-day notice issue in this proposed rule.

The Petitioners claim that the 30-day period is too long a timeframe for those sources where facility operations may necessitate a need to relocate unexpectedly. The Petitioners also stated their understanding that the requirement to provide the notice of relocation is for informational purposes and does not require any approval from the reviewing authority. Both of these issues are discussed below.

In response to the 30 day notification issue, we looked at both State and Federal rules pertaining to source relocation. Our review of state rules showed a range between 10 and 30 days advance notice specified for sources prior to relocation. In our major source PSD provisions at 52.21(i)(1)(viii)( d), addressing portable sources that relocate, we require that notice be


### 33273 Federal Register / Vol. 78, No. 107 / Tuesday, June 4, 2013 / Proposed Rules

11 The discussion below applies to true minor sources only. Synthetic minor sources are less likely to relocate, but if they do, we expect their permit conditions will address relocation. provided to the Administrator no later than 10 days prior to the relocation. Based on this information we are seeking comment on what advance notification period between 10 and 30 days is appropriate under the provisions of 40 CFR 49.160(d)(1).

While we agree with the Petitioners statement that there is no requirement for advance approval or a permit for relocation of a registered source prior to September 2, 2014, we are further clarifying and requesting comment on the permit requirements discussed below for sources relocating on or after September 2, 2014.

Source Obligation/Permit Requirements for Relocation

We believe that the types of true minor sources that typically relocate are ‘‘portable sources’’ such as: hot-mix asphalt plants, rock crushing operationsand concrete batch plants. These sourcetypes are designed to move the entire source from location to location, and, as a result, they are normally issued permits containing conditions that specify the owner/operator obligations prior to relocating. These portable sources can be permitted with either a site-specific permit or, if appropriate, through coverage under a general permit. In either case, multiple locations can be, and often are, pre-authorized in the permit. We also note that any general permits we may develop for such portable sources may contain provisions that would address source relocation. If the existing permit for a portable source does not contain authorization to relocate to a particular location, then the source must apply to the appropriate reviewing authority for a permit revision or new permits, as appropriate, to provide coverage for that additional location(s) and receive that permit before relocating.

For the relatively infrequent situation where a non-portable source is relocated, the owner must apply to the appropriate reviewing authority for a permit that covers the new location.

It’s important to note that the above discussion pertains to relocation of the entire minor source. If an owner/ operator chooses to relocate one or more pieces of equipment or emission units associated with a source from one source to another, the owner/operator would need to work with its reviewing authority (at the new location) to determine if such a relocation constitutes a modification under the Tribal minor NSR rule and requires a permit. Timing of Relocation

A relocating source can be subject to permit requirements depending on the date of relocation. 11 The three main scenarios are as follows:

• A registered true minor source constructed before September 2, 2014, that relocates before September 2, 2014, is not required to obtain any approval or permit prior to the relocation. Such a source is, however, required to provide advance notification of any planned relocation to the reviewing authority in accordance with 40 CR 49.160(d)(1).

• A true minor source constructed before September 2, 2014, that relocates on or after September 2, 2014, must obtain a permit from the appropriate reviewing authority prior to relocation if the source is subject to the Tribal minor NSR rule.

• A true minor source constructed on or after September 2, 2014, must obtain a permit for the original location and also for any subsequent relocation not specifically pre-authorized in the original permit.

To clarify the notification of relocation requirements further, we are proposing revisions to 40 CFR 49.160(d)(1) . We propose to replace the last two sentences of the existing regulatory text, addressing NSR permitting obligations, with more specific language concerning relocation situations. The proposed changes specify that a source moving from the jurisdiction of one reviewing authority to another on or after September 2, 2014, is required to notify the reviewing authority at the existing location and submit a permit application to the reviewing authority at the new location. In the case where the existing and new locations both fall within the jurisdiction of the same reviewing authority, the permit application for the new location will fulfill the relocation notification requirement.

As discussed above, we believe certain sources will hold permits that will contain specific conditions addressing requirements for relocation. In those cases, the provisions of the existing permit shall indicate the necessary notification of relocation requirements instead of those contained in 40 CFR 49.160(d)(1). V. Statutory and Executive Order
Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review

This action is not a ‘‘significant regulatory action’’ under the terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011) because it does not result in an impact greater than $100 million in any one year or raise novel legal or policy issues arising out of legal mandates, the President’s priorities, or the principles set forth in this Executive order.
B. Paperwork Reduction Act

This action does not impose any new information collection burden. The proposed rule would not create any new requirements under the Tribal minor NSR program, but rather would simplify minor source registrations and permit applications for some sources, potentially reducing burden. The Office of Management and Budget (OMB) has previously approved the information collection requirements contained in the existing regulations for the Tribal minor NSR program (40 CFR 49.151 through 49.161) under the provisions of the Paperwork Reduction Act, 44 U.S.C.

3501 et seq., and has assigned OMB control number 2060–0003. The OMB control numbers for the EPA’s regulations in 40 CFR are listed in 40
CFR Part 9.
C. Regulatory Flexibility Act

The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedures Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations and small governmental jurisdictions.

For purposes of assessing the impacts of this proposed action on small entities, small entity is defined as: (1) A small business as defined in the U.S. Small Business Administration size standards at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; or (3) asmall organization that is any not-forprofit enterprise that is independently


### 33274 Federal Register / Vol. 78, No. 107 / Tuesday, June 4, 2013 / Proposed Rules

owned and operated and is not dominant in its field.

After considering the economic impacts of this proposed action on small entities, I certify that this proposed action will not have a significant economic impact on a substantial number of small entities. In determining whether a rule has a significant economic impact on a substantial number of small entities, the impact of concern is any significant adverse economic impact on small entities, since the primary purpose of the regulatory flexibility analysis is to identify and address regulatory alternatives ‘‘which minimize any significant economic impact of the rule on small entities.’’ 5 U.S.C. 603 and 604. Thus, an agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, or otherwise has a positive economic effect, on all of the small entities subject to the rule.

The proposed rule would not create any new requirements under the Tribal minor NSR program, and therefore would not impose any additional burden on any sources (including small entities). The proposed rule would simplify minor source registrations and reduce the number of permit applications for some sources required under the existing rule, potentially reducing burden for all entities, including small entities. We have therefore concluded that this proposed rule will be neutral or relieve the regulatory burden for all affected small entities. We continue to be interested in the potential impacts of the proposed rule on small entities and welcome comments on issues related to such impacts.
D. Unfunded Mandates Reform Act

This rule does not contain a federal mandate that may result in expenditures of $100 million or more for state, local and tribal governments, in the aggregate, or the private sector in any 1 year. The proposed rule would not create any new requirements under the Tribal minor NSR program, but rather would simplify minor source registrations and reduce the number of permit applications for some sources, potentially reducing burden. Thus, this rule is not subject to the requirements of sections 202 or 205 of UMRA.

This rule is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. As noted previously, the effect of the proposed rule would be neutral or relieve regulatory burden.

E. Executive Order 13132: Federalism

This proposed rule does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. This proposed rule would revise the Tribal minor NSR program, which applies only in Indian country, and would not, therefore, affect the relationship between the national government and the states or the distribution of power and responsibilities among the various levels of government.

In the spirit of Executive Order 13132 and consistent with EPA policy to promote communications between the EPA and state and local governments, the EPA specifically solicits comment on this proposed rule from state and local officials.

F. Executive Order 13175: Consultation and Coordination With Indian Tribal
Governments

The EPA has concluded that this proposed rule will have tribal implications. However, it will neither impose substantial direct compliance costs on tribal governments, nor preempt tribal law. The proposed rule will have tribal implications since it would revise the Tribal minor NSRprogram, which applies to both triballyowned and privately-owned sources in Indian country. As with the existing rule, the revised rule would be implemented by the EPA, or a delegate tribal agency assisting the EPA with administration of the rules, until replaced by an EPA-approved tribal implementation plan. The effect of the proposed rule would be to simplify compliance with, and administration of, the Tribal minor NSR program, so any impact on tribes would be in the form of reduced burden and cost.

The EPA conducted substantial outreach and consultation with tribal officials and other tribal representatives during the development of the Tribal minor NSR program, and incorporated tribal views throughout the course of developing the program. These outreach efforts were summarized in section III.D of the preamble to the final rule (76 FR 38753). Regarding this proposal, we have presented highlights of the proposed changes to tribal environmental staff during a conference call with the National Tribal Air Association on February 28, 2013, and asked for comments. Regarding the list of exempted units/activities, we received a comment letter from one tribe during the comment period following proposal of the initial Tribal minor NSR rule and we considered those comments again in developing this proposed rule. We plan to offer consultation to the tribal governments during the proposed rule comment period.

The EPA specifically solicits additional comment on this proposed action from tribal officials.

G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks

The EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) as applying only to those regulatory actions that concern health or safety risks, such that the analysis required under section 5–501 of the Executive Order has the potential to influence the regulation. This action is not subject to Executive Order 13045 because it does not establish an environmental standard intended to mitigate health or safety risks.

H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution or Use

This action is not subject to Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not a significant regulatory action under Executive Order

12866.
I. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104– 113, 12(d) (15 U.S.C. 272 note) directs the EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards ( e.g., materials specifications, test methods, sampling procedures and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs the EPA to provide Congress, through the OMB, explanations when the agency decides not to use available and applicable voluntary consensus standards.

This proposed rulemaking does not involve technical standards. Therefore, the EPA did not consider the use of any voluntary consensus standards.


### 33275 Federal Register / Vol. 78, No. 107 / Tuesday, June 4, 2013 / Proposed Rules

J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations

Executive Order 12898 (59 FR 7629, February 16, 1994) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies and activities on minority populations and low-income populations in the United States.

The EPA has determined that this proposed rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it does not affect the level of protection provided to human health or the environment. The proposed rule would simplify minor source registrations and permit applications for some sources under the Tribal minor NSR program, but would not relax control requirements or result in greater emissions under the program. In fact, to the extent that the proposed rule might result in improved compliance with the program, it could result in emissions reductions in Indian country, which areoften home to both minority and lowincome populations.

K. Determination Under Section 307(d)

Pursuant to section 307(d)(1)(V) of the CAA, the Administrator determines that this action is subject to the provisions of section 307(d). Section 307(d)(1)(V) provides that the provisions of section 307(d) apply to ‘‘such other actions as the Administrator may determine.’’
VI. Statutory Authority

The statutory authority for this action is provided by sections 101, 110, 112, 114, 116 and 301 of the CAA as amended (42 U.S.C. 7401, 7410, 7412, 7414, 7416 and 7601).
