Approval and Promulgation of Implementation Plans; Designation of
Areas for Air Quality Planning Purposes; Redesignation of the Baltimore
Carbon Monoxide Area to Attainment and Approval of the Area's
Maintenance Plan and Emission Inventory; State of Maryland
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is approving a maintenance plan and a request to
redesignate the Baltimore carbon monoxide (CO) nonattainment area,
which is located within the Baltimore City Central Business District
(CBD) within the Baltimore Metropolitan Statistical Area. The
maintenance plan and redesignation requests were submitted by the State
of Maryland on September 20, 1995. Under the 1990 amendments of the
Clean Air Act (CAA) designations can be revised if sufficient data is
available to warrant such revisions. In this action, EPA is approving
Maryland's request because it meets the maintenance plan and
[[Page 55322]]
redesignation requirements set forth in the CAA. This action is being
taken under section 110 of the CAA.
DATES: This action will become effective on December 15, 1995, unless,
by November 30, 1995, adverse or critical comments are received. If the
effective date is delayed, timely notice will be published in the
Federal Register.

SUPPLEMENTARY INFORMATION: On September 20, 1995, the State of Maryland
submitted a formal revision to its State Implementation Plan (SIP). The
SIP revision consists of a maintenance plan, and a request to
redesignate the Baltimore CO nonattainment area from nonattainment to
attainment for carbon monoxide.
I. Background
The Baltimore area was designated a CO nonattainment area under the
Clean Air Act Amendments of 1990 (see 40 CFR 81.321). The National
Ambient Air Quality Standard (NAAQS) for CO is 9.5 parts per million
(ppm). Carbon monoxide nonattainment areas can be classified as
moderate or serious, based on their design values. Since the Baltimore
CO nonattainment area had a design value of 9.6 ppm (based on 1988 and
1989 data), the area was classified as moderate. The CAA established an
attainment date of December 31, 1995 for all moderate CO areas. The
Baltimore area has ambient air quality monitoring data showing
attainment of the CO NAAQS from 1989 through 1994. Therefore, in an
effort to comply with the CAA and to ensure continued attainment of the
NAAQS, on September 20, 1995 the State of Maryland submitted a CO
redesignation request and a maintenance plan for the Baltimore area.
Maryland submitted evidence that a public hearing was held on August 9,
1995 in Baltimore on this revision to the State's SIP.
II. Evaluation Criteria
Section 107(d)(3)(E) of the 1990 Clean Air Act Amendments provides
five specific requirements that an area must meet in order to be
redesignated from nonattainment to attainment:
1. The area must have attained the applicable NAAQS;
2. The area must have a fully approved SIP under section 110(k) of
CAA;
3. The air quality improvement must be permanent and enforceable;
4. The area must have a fully approved maintenance plan pursuant to
section 175A of the CAA;
5. The area must meet all applicable requirements under section 110
and Part D of the CAA.
III. Review of State Submittal
On September 20, 1995, EPA determined that the information received
from the State of Maryland constituted a complete redesignation request
under the general completeness criteria of 40 CFR part 51, appendix V,
Secs. 2.1 and 2.2. Maryland's redesignation request for the Baltimore
area meets the five requirements of section 107(d)(3)(E), noted above.
The following is a brief description of how the State has fulfilled
each of these requirements.
1. Attainment of the CO NAAQS
Maryland has quality-assured CO ambient air monitoring data showing
that the Baltimore area has met the CO NAAQS. The Maryland request is
based on an analysis of quality-assured CO air monitoring data which is
relevant to the maintenance plan and to the redesignation request. To
attain the CO NAAQS, an area must have complete quality-assured data
showing no more than one exceedance of the standard per year over at
least two consecutive years. The ambient air CO monitoring data for
calendar year 1989 through calendar year 1995, relied upon by Maryland
in its redesignation request, shows no violations of the CO NAAQS in
the Baltimore area during this time. Because the area has complete
quality assured data showing no more than one exceedance of the
standard per year over at least two consecutive years (1994 and 1995),
the area has met the first statutory criterion of attainment of the CO
NAAQS (40 CFR 50.8 and appendix C). Maryland has committed to continue
monitoring in this area in accordance with 40 CFR part 58.
2. Fully Approved SIP Under Section 110(k) of the CAA
Maryland's CO SIP is fully approved by EPA as meeting all the
requirements of Section 110(a)(2)(I) of the Act, including the
requirements of Part D (relating to nonattainment), which were due
prior to the date of Maryland's redesignation request. Maryland's CO
SIP was fully approved by EPA on September 19, 1984, at 40 CFR
52.1070(c)(71), (49 FR 36645). The 1990 CAA required that nonattainment
areas achieve specific new requirements depending on the severity of
the nonattainment classification. Requirements for the Baltimore area
included the preparation of a 1990 emission inventory with periodic
updates, adoption of an oxygenated fuels program, the development of
contingency measures, and development of conformity procedures. Each of
these requirements added by the 1990 Amendments to the CAA are
discussed in greater detail below.
Consistent with the October 14, 1994 EPA guidance from Mary D.
Nichols entitled ``Part D New Source Review (Part D NSR) Requirements
for Areas Requesting Redesignation to Attainment,'' EPA is not
requiring full approval of a Part D NSR program by Maryland as a
prerequisite for redesignation to attainment. Under this guidance,
nonattainment areas may be redesignated to attainment notwithstanding
the lack of a fully-approved Part D NSR program, so long as the program
is not relied upon for maintenance. Because the Baltimore area is being
redesignated to attainment by this action, Maryland's Prevention of
Significant Deterioration (PSD) requirements will be applicable to new
or modified sources in the Baltimore area. Maryland has been delegated
PSD authority (see Sec. 52.1116 Maryland, 45 FR 52741, August 7, 1980,
as amended 47 FR 7835, February 23, 1982).
A. Emission Inventory
On March 24, 1994, Maryland submitted a 1990 base year emissions
inventory to EPA for review and approval. This inventory was used as
the basis for calculations to demonstrate maintenance. Maryland's
submittal contains the detailed inventory data and summaries by source
category. Maryland's submittal also contains information related to how
it comported with EPA's guidance, and which model and emissions factors
were used (note, the MOBILE 5a model was used), how vehicle miles
travelled (VMT) data was generated, and other technical information
verifying the emission inventory. A summary of the base year and
projected maintenance year inventories are shown in the following table
in this section.
Section 172(c)(3) of the CAA requires that nonattainment plan
provisions
[[Page 55323]]
include a comprehensive, accurate, and current inventory of actual
emissions from all sources of relevant pollutants in the nonattainment
area. Maryland included the requisite inventory in the redesignation
request and maintenance plan SIP revision. The base year for the
inventory was 1990, using a three month CO season of December 1990
through February 1991. Stationary point sources, stationary area
sources, on-road mobile sources, and off-road mobile sources of CO were
included in the inventory. The following table, Table 1, presents a
summary of the attainment year's (1990) and projected year's (2007) CO
peak season daily emissions estimates in tons per winter day (tpd) by
source category:

------------------------------------------------------------------------
Available guidance for preparing emission inventories is provided
in the General Preamble (57 FR 13498, April 16, 1992).
Section 110(k) of the CAA sets out provisions governing the EPA's
review of base year emission inventory submittals in order to determine
approval or disapproval under section 187(a)(1). The EPA is granting
approval of the Maryland 1990 base year CO emissions inventories as
found in the Baltimore CO Redesignation Request, based on the EPA's
technical review of the CO inventory. For further details on the
emission inventory, the reader is referred to the Technical Support
Document, which is available for review at the addresses provided
above.
B. Oxygenated Gasoline
Section 211(m) of the CAA requires that each State in which there
is located a CO nonattainment area with a design value of 9.5 ppm or
above based on data for the 2-year period of 1988 and 1989 shall submit
a SIP revision which requires the implementation of an oxygenated
gasoline program in the Consolidated Metropolitan Statistical Area
(CMSA) or Metropolitan Statistical Area (MSA) in which the
nonattainment area is located. The Baltimore area has a design value
above 9.5 ppm based on 1988 and 1989 data and consequently was subject
to the requirement to adopt an oxygenated fuel program. Maryland
submitted an oxygenated gasoline SIP revision for the Baltimore MSA to
EPA on November 13, 1992. EPA approved the SIP revision for Maryland on
June 6, 1994. As noted in the Maryland redesignation request, the State
has relegated the oxygenated fuel program to contingency status under
the redesignation. Through emergency rulemaking procedures, Maryland
modified these regulations to provide for the oxygenated gasoline
control period to be required in future years as a contingency measure
to ensure maintenance of the National Ambient Air Quality Standard
(NAAQS) for CO. The rule change states that upon a monitored violation
of the CO NAAQS (two or more exceedances of the CO NAAQS in a single
calendar year), the oxygenated gasoline control period shall be
reinstated. Under the amended regulations, a notice by July 1 of any
year for an area would reinstate the oxygenated gasoline requirements
beginning on November 1 of that year. This emergency regulation change
is effective from September 13, 1995 through February 28, 1996.
Maryland is currently pursuing permanent adoption of these regulations,
and final adoption of the permanent rule change should become effective
in January 1996.
Maryland's maintenance demonstration, described below, asserts that
oxygenated gasoline in the Baltimore MSA is not necessary for continued
maintenance of the CO NAAQS. Consequently, EPA is approving Maryland's
use of oxygenated gasoline as a contingency measure for the Baltimore
area.
C. Conformity
Under section 176(c) of the CAA, states were required to submit
revisions to their SIPs that include criteria and procedures to ensure
that Federal actions conform to the air quality planning goals in the
applicable SIPs. The requirement to determine conformity applies to
transportation plans, programs and projects developed, funded or
approved under Title 23 U.S.C. or the Federal Transit Act
(``transportation conformity''), as well as all other Federal actions
(``general conformity''). Congress provided for the State revisions to
be submitted one year after the date of promulgation of final EPA
conformity regulations. EPA promulgated final transportation conformity
regulations on November 24, 1993 (58 FR 62188) and final general
conformity regulations on November 30, 1993 (58 FR 63214). These
conformity rules require that the States adopt both transportation and
general conformity provisions in the SIP for areas designated
nonattainment or subject to a maintenance plan approved under CAA
section 175A. Pursuant to Sec. 51.396 of the transportation conformity
rule and Sec. 51.851 of the general conformity rule, the State of
Maryland was required to submit a SIP revision containing
transportation conformity criteria and procedures consistent with those
established in the Federal rule by November 25, 1994. Similarly,
Maryland was required to submit a SIP revision containing general
conformity criteria and procedures consistent with those established in
the Federal rule by December 1, 1994. Maryland submitted transportation
conformity SIP revisions to EPA on May 16, 1995. Furthermore, Maryland
submitted, on May 15, 1995, SIP revisions for general conformity.
Although this redesignation request was submitted to EPA after the
due dates for the SIP revisions for transportation conformity (58 FR
62188) and general conformity (58 FR 63214) rules, EPA believes it is
reasonable to interpret the conformity requirements as not being
applicable requirements for purposes of evaluating the redesignation
request under section 107(d). The rationale for this is based on a
combination of two factors. First, the requirement to submit SIP
revisions to comply with the conformity provisions of the Act continues
to apply to areas after redesignation to attainment. Therefore, the
State remains obligated to adopt the transportation and general
conformity rules even after redesignation and would risk sanctions for
failure to do so. While redesignation of an area to attainment enables
the area to avoid further compliance with most requirements of section
110 and part D, since those requirements are linked to the
nonattainment status of an area, the conformity requirements apply to
both nonattainment and maintenance areas. Second, EPA's federal
conformity rules require the performance of conformity analyses in the
absence of state-adopted rules. Therefore, a delay in adopting State
rules does not relieve an area from the obligation to implement
conformity requirements.
Because areas are subject to the conformity requirements regardless
of whether they are redesignated to attainment and must implement
conformity under Federal rules if State rules are not yet adopted, EPA
believes it is reasonable to view these requirements as not being
applicable requirements for purposes of evaluating a redesignation
request.
Therefore, with this notice, EPA is modifying its national policy
regarding
[[Page 55324]]
the interpretation of the provisions of section 107(d)(3)(E) concerning
the applicable requirements for purposes of reviewing a carbon monoxide
redesignation request. Under this new policy, for the reasons just
discussed, EPA believes that the CO redesignation request for the
Baltimore area may be approved notwithstanding the lack of approved
state transportation and general conformity rules.
3. Improvement in Air Quality Due to Permanent and Enforceable Measures
EPA approved Maryland's CO SIP under the 1977 CAA. Emission
reductions achieved through the implementation of control measures
contained in that SIP are enforceable. Maryland cites the Federal Motor
Vehicle Control Program (FMVCP) as the major source of reductions that
led to attainment of the CO standard. Stationary sources have also been
required to improve combustion efficiency through the Best Available
Control Technology (BACT) requirements. Both of these measures are
considered permanent and enforceable.
As discussed above, the State initially attained the NAAQS in 1989
with monitored attainment through 1994. This indicates that the
improvements are due to the permanent and enforceable measures
contained in the 1982 CO SIP.
Maryland has demonstrated that actual enforceable emission
reductions are responsible for the air quality improvement and that the
CO emissions in the base year are not artificially low due to local
economic downturn. EPA finds that the combination of certain existing
EPA-approved SIP and federal measures contribute to the permanence and
enforceability of reduction in ambient CO levels that have allowed the
area to attain the NAAQS.
4. Fully Approved Maintenance Plan Under Section 175A
Section 175A of the CAA sets forth the elements of a maintenance
plan for areas seeking redesignation from nonattainment to attainment.
The plan must demonstrate continued attainment of the applicable
NAAQS for at least ten years after the Administrator approves a
redesignation to attainment. Eight years after the redesignation, the
State must submit a revised maintenance plan which demonstrates
attainment for the ten years following the initial ten-year period. To
provide for the possibility of future NAAQS violations, the maintenance
plan must contain contingency measures, with a schedule for
implementation adequate to assure prompt correction of any air quality
problems. In this notice, EPA is approving the State of Maryland's
maintenance plan for the Baltimore area because EPA finds that
Maryland's submittal meets the requirements of section 175A.
A. Attainment Emission Inventory
As previously noted, on March 24, 1994, Maryland submitted a 1990
base year emissions inventory to EPA for review and approval. The
inventory includes emissions from area, stationary, and mobile sources
using 1990 as the base year for calculations.
The State submittal contains the detailed inventory data and
summaries by county and source category. The comprehensive base year
emissions inventory was submitted in the National Emission Data System
format. This inventory was prepared in accordance with EPA guidance.
The 1990 inventory can be considered representative of attainment
conditions because the CO NAAQS was not violated during 1990. Maryland
established the 1990 inventory as the attainment inventory, and
forecasted future emissions out to the year 2007 in its redesignation
request. The State projected emissions for the end of the maintenance
period using appropriate growth factors, consistent with EPA guidance.
To project future emissions from mobile sources, MOBILE5a was used to
assess the benefits gained from federally mandated control measures.
Maryland assumed the following control programs, when projecting the
inventory: FMVCP, the 1992 Reid Vapor Pressure Program, Tier 1 controls
on new vehicles, Evaporative Emissions Control Program, Federal
Reformulated Gasoline, Enhance Inspection & Maintenance, Low Emission
Vehicles, Stage II Vapor Recovery, and On-Board Controls. Since these
programs are either a) federal measures that are currently adopted or
will be adopted in the future under the CAA, or b) state regulations
which are currently approved into the SIP, they constitute appropriate
assumptions for future modeling scenarios. Stationary source emissions
and off-road mobile source emissions were projected using the 1990 base
year inventory and multiplying with appropriate projection factors. The
area source future emissions were projected using the 1990 base year
inventory and multiplying the inventory with household, population, and
employment growth factors from the Round 5 Cooperative forecasting
process conducted by the Baltimore Metropolitan Council.
B. Demonstration of Maintenance-Projected Inventories
Total CO emissions were projected from 1990 base year out to 2005
and 2010, and then interpolated for the maintenance plan's projection
year, 2007. These projected inventories were prepared in accordance
with EPA guidance. Maryland will not implement the oxygenated fuel
program in the Baltimore MSA unless a violation of the standard
triggers the program for the following CO season.
The projections show that calculated CO emissions, assuming no
oxygenated fuels program, are not expected to exceed the level of the
base year inventory during this time period. Therefore, it is
anticipated that the Baltimore area will maintain the CO standard
without the program, and the oxygenated fuel program will not need to
be implemented following redesignation, except as a contingency
measure.
C. Verification of Continued Attainment
Continued attainment of the CO NAAQS in the Baltimore area depends,
in part, on the State's efforts toward tracking indicators of continued
attainment during the maintenance period. In addition, comprehensive
reviews will be conducted periodically of the factors used to develop
the attainment inventories and those used to project CO emissions
levels for 2007. If any of the localities find significant differences
between actual and projected growth, updated emission inventories will
be developed to compare with the projections.
D. Contingency Plan
The level of CO emissions in the Baltimore area will largely
determine its ability to stay in compliance with the CO NAAQS in the
future. Despite the State's best efforts to demonstrate continued
compliance with the NAAQS, the ambient air pollutant concentrations may
exceed or violate the NAAQS. Section 175(A)(d) of the CAA requires that
the contingency provisions include a requirement that the State
implement all measures contained in the SIP prior to redesignation.
Therefore, Maryland has provided for oxygenated fuels as a contingency
measure in the event of a future CO air quality problem. The plan
contains an acceptable triggering mechanism (a violation of the CO
standard) to determine when the contingency measure is needed.
Maryland has changed its oxygenated fuel rule, through emergency
rulemaking procedures, to require oxygenated gasoline as a contingency
[[Page 55325]]
measure for the purposes of redesignation. Maryland has also provided a
schedule to EPA for the permanent adoption of the oxygenated fuel
regulation change. EPA finds this an acceptable contingency measure
which fulfills the requirements of section 175(A)(d).
E. Subsequent Maintenance Plan Revisions
In accordance with section 175A(b) of the CAA, the State must
submit a revised maintenance SIP eight years after the area is
redesignated to attainment. Such a revised SIP will provide for
maintenance for an additional ten years.
5. Meeting Applicable Requirements of Section 110 and Part D
In Section III.2. above, EPA sets forth the basis for its
conclusion that Maryland has a fully approved SIP which meets the
applicable requirements of Section 110 and Part D of the CAA.
EPA is approving this SIP revision without prior proposal because
the Agency views this as a noncontroversial amendment and anticipates
no adverse comments. However, in a separate document in this Federal
Register publication, EPA is proposing to approve the SIP revision
should adverse or critical comments be filed. This action will be
effective December 15, 1995, unless, by November 30, 1995, adverse or
critical comments are received.
If EPA receives such comments, this action will be withdrawn before
the effective date by publishing a subsequent document that will
withdraw the final action. All public comments received will then be
addressed in a subsequent final rule based on this action serving as a
proposed rule. EPA will not institute a second comment period on this
action. Any parties interested in commenting on this action should do
so at this time. If no such comments are received, the public is
advised that this action will be effective on December 15, 1995.
Final Action
EPA is approving the Baltimore area CO maintenance plan because it
meets the requirements set forth in section 175A of the CAA. In
addition, the Agency is approving the request and redesignating the
Baltimore CO nonattainment area to attainment, because the State has
demonstrated compliance with the requirements of section 107(d)(3)(E)
for redesignation. EPA is also approving Maryland's 1990 base year CO
emissions inventory for the Baltimore MSA, as found in the State's
redesignation request and maintenance plan. The EPA is publishing this
action without prior proposal because the Agency views this as a
noncontroversial amendment and anticipates no adverse comments.
However, in a separate document in this Federal Register publication,
the EPA is proposing to approve the SIP revision should adverse or
critical comments be filed. This action will be effective December 15,
1995, unless, by November 30, 1995, adverse or critical comments are
received. If the EPA receives such comments, this action will be
withdrawn before the effective date by publishing a subsequent document
that will withdraw the final action. All public comments received will
then be addressed in a subsequent final rule based on this action
serving as a proposed rule. The EPA will not institute a second comment
period on this action. Any parties interested in commenting on this
action should do so at this time. If no such comments are received, the
public is advised that this action will be effective December 15, 1995.
Nothing in this action should be construed as permitting, allowing,
or establishing a precedent for any future request for revision to any
state implementation plan. Each request for revision to the state
implementation plan shall be considered separately in light of specific
technical, economic, and environmental factors and in relation to
relevant statutory and regulatory requirements.
Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA
must prepare a regulatory flexibility analysis assessing the impact of
any proposed or final rule on small entities. 5 U.S.C. 603 and 604.
Alternatively, EPA may certify that the rule will not have a
significant impact on a substantial number of small entities. Small
entities include small businesses, small not-for-profit enterprises,
and government entities with jurisdiction over populations of less than
50,000.
Under Section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule that includes a Federal mandate that may result in estimated
costs to State, local, or tribal governments in the aggregate; or to
the private sector, of $100 million or more. Under section 205, EPA
must select the most cost-effective and least burdensome alternative
that achieves the objectives of the rule and is consistent with
statutory requirements. Section 203 requires EPA to establish a plan
for informing and advising any small governments that may be
significantly or uniquely impacted by the rule.
EPA has determined that the approval action promulgated does not
include a Federal mandate that may result in estimated costs of $100
million or more to either State, local, or tribal governments in the
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under State or local law, and imposes no new
Federal requirements. Accordingly, no additional costs to State, local,
or tribal governments, or to the private sector, result from this
action.
Redesignation of an area to attainment under section 107(d)(3)(E)
of the CAA does not impose any new requirements on small entities.
Redesignation is an action that affects the status of a geographical
area and does not impose any regulatory requirements on sources. The
Administrator certifies that the approval of the redesignation request
will not affect a substantial number of small entities.
The CO SIP is designed to satisfy the requirements of part D of the
CAA and to provide for attainment and maintenance of the CO NAAQS. This
final redesignation should not be interpreted as authorizing the State
to delete, alter, or rescind any of the CO emission limitations and
restrictions contained in the approved CO SIP. Changes to CO SIP
regulations rendering them less stringent than those contained in the
EPA approved plan cannot be made unless a revised plan for attainment
and maintenance is submitted to and approved by EPA. Unauthorized
relaxations, deletions, and changes could result in both a finding of
non-implementation (section 179(a) of the CAA) and in a SIP deficiency
call made pursuant to sections 110(a)(2)(H) and 110(k)(2) of the CAA.
SIP approvals under section 110 and subchapter I, part D of the CAA
do not create any new requirements, but simply approve requirements
that the State is already imposing. Therefore, because the federal SIP
approval does not impose any new requirements, it does not have any
economic impact on any small entities. Redesignation of an area to
attainment under section 107(d)(3)(E) of the CAA does not impose any
new requirements on small entities.
This action has been classified as a Table 3 action for signature
by the Regional Administrator under the procedures published in the
Federal Register on January 19, 1989 (54 FR
[[Page 55326]]
2214-2225), as revised by a July 10, 1995 memorandum from Mary Nichols,
Assistant Administrator for Air and Radiation. The Office of Management
and Budget (OMB) has exempted this regulatory action from E.O. 12866
review.
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by January 2, 1996. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this rule for the purposes of judicial
review nor does it extend the time within which a petition for judicial
review may be filed, and shall not postpone the effectiveness of such
rule or action. This rulemaking redesignating the Baltimore CO
nonattainment area to attainment, approving the maintenance plan
submitted by the Maryland Department of the Environment on September
20, 1995, and approving the CO emissions inventory submitted on March
24, 1994 may not be challenged later in proceedings to enforce its
requirements. (See section 307(b)(2).)
