Designation of Areas for Air Quality Planning Purposes; State of South Dakota; Approval of Redesignation Request
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
SUMMARY: EPA is proposing to approve a September 30, 2005 request from the designee of the Governor of South Dakota to redesignate the ``Rapid City Area'' under section 107 of the Clean Air Act (CAA) from unclassifiable to attainment for PM-10. EPA is proposing to approve the redesignation request because the State has adequately demonstrated that the ``Rapid City Area'' is in attainment of the PM-10 National Ambient Air Quality Standards (NAAQS) and has committed to the continuation of fugitive dust controls that should help ensure that the area continues to attain the PM-10 NAAQS. The requirements that will apply in the ``Rapid City Area'' will not change as a result of this action because, for the purposes of the requirements of the CAA, unclassifiable and attainment areas are treated the same. This action is being taken under section 107 of the Clean Air Act.

Background
The State of South Dakota has two areas designated under section 107 of the Act for PM-10 in 40 CFR 81.342, both of which are designated as unclassifiable: the ``Rapid City Area'' and the ``Rest of State'' (see 60 FR 55800, November 3, 1995, for the initial promulgation of PM- 10 table in 40 CFR 81.342). EPA designated these areas as unclassifiable, rather than attainment, to be consistent with section 107(d)(4)(B) of the Act, which states that any area not initially designated as nonattainment for PM-10 shall be designated unclassifiable. Both ``unclassifiable'' and ``attainment'' areas have the same status relative to the applicable requirements of the Act. However, States do have the option of requesting redesignation of such areas from unclassifiable to attainment for PM-10, if certain criteria are met. Generally, EPA will look for the following elements to redesignate an area from unclassifiable to attainment for PM-10:
-
A request from the Governor (or his/her designee) to redesignate an area from unclassifiable to attainment for PM-10 pursuant to section 107(d)(3)(D) of the Act;
-
Verification of three consecutive years of PM-10 data for the area showing attainment; and
[[Page 73185]]
-
Some assurance that the State will continue to implement any control measures in place that have helped the area attain or maintain the PM-10 NAAQS.

Evaluation of State's Submittal
On September 30, 2005, the designee of the Governor of South Dakota submitted a request pursuant to section 107(d)(3)(D) of the CAA for the ``Rapid City Area'' to be redesignated from unclassifiable to attainment for PM-10. The State's letter indicates that the ambient air monitoring network, local and state regulations to control fugitive dust, and high wind advisory system to alert the public already in place in Rapid City will be maintained.
As stated in section II.B above, in order to be redesignated, an area must have three consecutive years of PM-10 data showing attainment. The State of South Dakota has maintained an appropriate PM10 monitoring network. To demonstrate attainment, the PM-10 monitoring data at each site must show that the expected 3-year annual arithmetic mean did not exceed 50 micrograms per cubic meter and the expected number of 24-hour days with PM-10 concentrations greater than 150 micrograms per cubic meter does not exceed more than one day per year. The expected 3-year annual arithmetic mean and 24-hour concentrations are calculated using Appendix K of 40 CFR, part 50. Appendix K of 40 CFR, part 50 requires that three consecutive years of complete data be used to demonstrate compliance. A complete year of data is based on a valid data capture efficiency of 75 percent of the scheduled sampling days in each of the calendar quarters used in the three year period. Sampling data from the air monitoring sites operating in 2002, 2003, and 2004 are being used to demonstrate that Rapid City should be redesignated from unclassifiable to attainment. The monitoring sites in Rapid City that operated during all three years are the Library (Air Quality System (AQS) 46-103-1001), National Guard (AQS 46-103-0013), and Black Hawk (AQS 46-0093-0001) sites. In addition, data from the most recent maximum concentration sites, the Fire Station, AQS 46-103- 0019, and the Credit Union, AQS 46-103-0020, are being used to support the redesignation even though complete data was not collected in 2003. The Fire Station site operated from 2000 until April 2003 when the building where the monitor was located was torn down, and the Fire Station site was replaced by the Credit Union site. The Credit Union site is located 30 meters east of the Fire Station site and began operating in October 2003. Currently, the Credit Union is the high PM- 10 concentration site for the western Rapid City area. As a result of having to move the high PM-10 concentration site, the State was unable to collect a full year of data in 2003. During 2003, the State was only able to collect PM-10 concentration data from January through April at the Fire Station site and October through December at the Credit Union site. Although this created a gap in the PM-10 concentrations for the high concentration site in Rapid City, EPA is using the data from these sites to support the redesignation because the data that was collected during 2002-2004 shows levels less than the NAAQS.
The only high concentration measurements were tied to high wind alert events. Under relevant EPA regulations and policies, these data are not used in determining attainment. As explained in greater detail below, South Dakota has developed and implemented a Natural Events Action Plan (NEAP) to help address anthropogenic emissions during high wind events. EPA's review of the relevant data indicates that the ``Rapid City Area'' is attaining both the 24-hour and annual PM-10 NAAQS.
As stated in section II.C above, we generally want to know that the State will continue to implement existing control measures that have helped the area attain or maintain the NAAQS. The State of South Dakota has an approved State Implementation Plan (SIP), which includes Article 74:36 of the Administrative Rules of South Dakota, to help ensure that the PM-10 NAAQS will be maintained. First, the State has a minor source construction and operating permit program in ARSD 74:36:04 and a major source permit program in ARSD 74:36:05. These regulations allow the State to issue a permit for a new source to construct or operate only when it has been shown that the new source will not prevent or interfere with attainment or maintenance of the NAAQS. Further, the State has been delegated authority to implement the Federal prevention of significant deterioration (PSD) permitting program in 40 CFR 52.21, which includes, among other things, the requirement that new and modified major stationary sources comply with the PM-10 increments and apply best available control technology (BACT). Thus, the State's permitting requirements should ensure that new growth in stationary source emissions does not impact attainment or maintenance of the PM-10 NAAQS in the ``Rapid City Area''.
In addition to the permitting requirements, the State has specific regulations that control the emissions of particulate matter, including PM-10, in ARSD 74:36:06, 74:36:07, 74:36:15, 74:36:17, and 74:36:18. These include particulate emission limits for fuel-burning units, process industry units, incinerators, and wood waste burners; a 20% opacity limit that generally applies to all sources; open burning requirements; fugitive dust emission controls for street sanding and deicing; and fugitive dust emission controls from construction and continuous operations on State owned property. EPA believes these existing State regulations, which have been approved by EPA as part of the SIP, will help to ensure that the ``Rapid City Area'' maintains the PM-10 NAAQS.
The State has also developed a NEAP for Rapid City to address PM-10 exceedances that are natural events resulting from high winds and periods of prolonged drought. In July of 1998, the State developed and finalized a NEAP in accordance with EPA's 1996 Natural Events Policy (NEP), submitted it to EPA, and received EPA approval on the plan. In accordance with the NEP, the State also submitted a five-year review of their NEAP to EPA, and EPA approved the review on August 4, 2005. The NEAP contains control measures to minimize fugitive dust emissions during high wind events and also contains procedures for public notification when high wind events are occurring so members of the public can take extra precautions to protect themselves. The NEAP will remain in effect after redesignation to attainment. Finally, the State of South Dakota commits to maintain an appropriate PM10 monitoring network. This network will include a maximum concentration site, and data from the network will be submitted to EPA's Air Quality System database on a quarterly basis.
Based on the foregoing, EPA believes it is appropriate to approve the State's request to redesignate the ``Rapid City Area'' from unclassifiable to attainment for PM-10. Based on monitoring data, EPA will be aware if the attainment status of this area changes in the future and triggers the need for additional PM-10 controls as required by the Act.

Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed action is not a ``significant regulatory action'' and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This proposed action merely proposes to approve a redesignation to attainment and imposes no additional requirements beyond those imposed by state law. Redesignation of an area to attainment under section 107 of the Clean Air Act is an action that affects the attainment status of a geographical area and does not impose any new regulatory requirements on sources. Accordingly, the Administrator certifies that this proposed rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule proposes to approve a redesignation to attainment and does not impose any additional enforceable duty beyond that required by state law, it 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).
This proposed rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does 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 (64 FR 43255, August 10, 1999). This action merely proposes to approve a redesignation to attainment and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This proposed rule also is not subject to Executive Order 13045 ``Protection of Children from Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997), because it is not economically significant.
Section 12(d) of the National Technology Transfer Advancement Act (NTTAA) of 1995, Public Law 104-113, section 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards (VCS) in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impracticable. VCS are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by VCS bodies. This action does not involve technical standards. Therefore, EPA did not consider the use of any VCS. This proposed rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
