40 CFR Part 81
[R08-OAR-2005-SD-0002; FRL-8005-1]
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.

II. 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. 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;
B. Verification of three consecutive years of PM-10 data for the
area showing attainment; and
[[Page 73185]]
C. 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.
III. 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.
IV. Proposed Action
EPA is proposing to approve the State of South Dakota's request for
redesignation under section 107 of the CAA from unclassifiable to
attainment for PM-10. EPA is soliciting public comments on this
proposed action or on other relevant matters. Any comments will be
considered before we take final action. Interested parties may
participate in the Federal rulemaking
[[Page 73186]]
procedure by submitting written comments in accordance with the
instructions outlined earlier in this notice.
V. 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.).
