SUPPLEMENTARY INFORMATION: On June 8, 1993 and July 19, 1993, the State

of Maryland submitted revisions to its ozone SIP to establish statewide

applicability for Maryland's VOC RACT regulations, lower the

applicability threshold for VOC RACT regulations, and correct

deficiencies in Maryland's Stage I Vapor Recovery (Stage I) regulation.

These revisions were submitted to comply with the RACT ``Catch-up'' and

``Fix-up'' provisions of the Act. Previously, on April 5, 1991, April

2, 1992, and January 18, 1993, Maryland submitted SIP revisions to

comply with the RACT Fix-up requirements. These submittals also contain

revisions to Maryland's Stage I regulation.

This rulemaking action addresses revisions to Maryland's Stage I

regulation (COMAR 26.11.13.04) submitted by Maryland on April 5, 1991,

April 2, 1992, January 18, 1993, June 8, 1993 and July 19, 1993. This

rulemaking action also addresses revisions to Maryland's VOC RACT

regulations, COMAR 26.11.11.02, 26.11.11.04, 26.11.13.01, 26.11.13.02,

26.11.13.07, 26.11.19.01, 26.11.19.02A, F and H, and 26.11.19.10,

submitted on June 8, 1993 and July 19, 1993.

Maryland's June 8, 1993 and July 19, 1993 submittals also contain

revisions to Maryland's generic VOC RACT and minor source regulations,

COMAR 26.11.19.02G and 26.11.06.06 A and B, respectively. Revisions to

COMAR 26.11.19.02G and 26.11.06.06 A and B are the subject of a

separate rulemaking action.

I. Background

RACT Fix-up Requirement

Under the pre-amended Act (i.e the Act prior to the 1990

Amendments), ozone nonattainment areas were required to adopt RACT

rules for sources of VOC emissions. EPA issued three sets of control

technique guideline documents (CTGs), establishing a ``presumptive

norm'' for RACT for various categories of VOC sources. The three sets

of CTGs were (1) Group I--issued before January 1978 (15 CTGs); (2)

Group II--issued in 1978 (9 CTGs); and (3) Group III--issued in the

early 1980's (5 CTGs). Those sources not covered by a CTG were called

non-CTG sources.

EPA determined that an area's SIP-approved attainment date

established which RACT rules the area needed to adopt and implement.

Under pre-amended section 172(a)(1), ozone nonattainment areas were

generally required to attain the ozone standard by December 31, 1982.

Those areas that submitted an attainment demonstration projecting

attainment by that date were required to adopt RACT for sources covered

by the Group I and II CTGs. Those areas that sought an extension of the

attainment date under section 172(a)(2) to as late as December 31, 1987

were required to adopt RACT for all CTG sources and for all major non-

CTG sources (i.e. sources having potential VOC emissions of 100 tons

per year (TPY) or more).

Under the pre-amended Act, EPA designated the Baltimore, Washington

DC, and Philadelphia areas as nonattainment. Under the pre-amended Act,

the Baltimore area included the City of Baltimore and Anne Arundel,

Baltimore, Carroll, Harford, and Howard Counties. Under the pre-amended

Act, the Washington DC area included Montgomery and Prince George's

Counties in Maryland, as well as the District of Columbia and a portion

of Northern Virginia. Under the pre-amended Act, the Philadelphia

nonattainment area did not include any areas in the State of Maryland.

The Baltimore and Washington DC nonattainment areas each

established a pre-enactment (i.e. prior to enactment of the 1990

Amendments) attainment date of December 31, 1987 and, therefore, were

required to adopt RACT for Group I, II, and III CTG categories as well

as non-CTG VOC sources with the potential to emit 100 TPY or more.

However, these areas did not attain the ozone standard by the approved

attainment date. On May 26, 1988, EPA notified the Governor of Maryland

that portions of Maryland's SIP were [[Page 2019]] inadequate to attain

and maintain the ozone standard and requested that deficiencies in the

existing SIP be corrected (EPA's SIP Call). On November 15, 1990,

amendments to the 1977 Clean Air Act were enacted. Pub. L. 101-549, 104

Stat. 2399, codified at 42 U.S.C. 7401-7671q. In amended section

182(a)(2)(A) of the Act, Congress statutorily adopted the requirement

that pre-enactment ozone nonattainment areas which retained their

designation of nonattainment and were classified as marginal or above

fix their deficient RACT rules for ozone by May 15, 1991. This is known

as the RACT fix-up requirement.

Under the amended Act, EPA and the States were required to review

the designation of areas and to redesignate areas as nonattainment for

ozone if the air quality data from 1987, 1988, and 1989 indicated that

the area was violating the ozone standard. On November 6, 1991 and

November 30, 1992, EPA issued those designations. 56 FR 56694 and 57 FR

56762. The Baltimore and Philadelphia nonattainment areas retained

their designations of nonattainment and were classified as severe. The

Washington DC nonattainment area also retained its designation of

nonattainment and was classified as serious. 56 FR 56694 (Nov. 6,

1991).

RACT Catch-up Requirement

Section 182(b)(2) of the amended Act requires States to adopt RACT

rules for all areas designated nonattainment for ozone and classified

as moderate or above. There are three parts to the section 182(b)(2)

RACT requirement: (1) RACT for sources covered by an existing CTG (i.e.

a CTG issued prior to the enactment of the Amendments); (2) RACT for

sources covered by a post-enactment CTG; and (3) all major sources not

covered by a CTG. This RACT requirement makes nonattainment areas that

previously were exempt from RACT requirements ``catch up'' to those

nonattainment areas that became subject to those requirements during an

earlier period, and therefore is known as the RACT Catch-up

requirement. In addition, it requires newly designated ozone

nonattainment areas to adopt RACT rules consistent with those for

previously designated nonattainment areas.

Since the Baltimore and Washington DC nonattainment areas were

previously required to adopt RACT for Group I, II, and III CTG sources,

to meet the RACT Catch-up requirement, Maryland was not required to

submit additional existing CTG RACT rules for those areas. However, the

size threshold for defining a major source for severe and serious areas

has been lowered under the amended Act to cover sources that have the

potential to emit 25 and 50 TPY of VOC or more, respectively.

Therefore, Maryland was required to adopt RACT rules for all sources

that exceed these cut-offs.

The pre-enactment Washington DC and Philadelphia nonattainment

areas retained their nonattainment designations, and EPA extended the

boundaries of these nonattainment areas. The Washington DC

nonattainment area was extended to include Calvert, Charles, and

Frederick Counties in Maryland. The Philadelphia nonattainment area was

expanded to include Cecil County, Maryland. 56 FR 56694 (November 6,

1991). Therefore, under the RACT Catch-up provision of section

182(b)(2), the State was required, for these portions of the

nonattainment areas, to submit RACT rules covering all pre-enactment

CTGs, to identify all sources the State anticipates will be covered by

a post-enactment CTG and to submit non-CTG rules for all remaining

major sources with the potential to emit 50 and 25 TPY VOC or more in

the Washington DC and Philadelphia nonattainment areas, respectively.

As stated above, EPA and the States reviewed the designation of

areas and redesignate areas as nonattainment for ozone using air

quality data from 1987, 1988, and 1989. EPA issued those designations

on November 6, 1991 and November 30, 1992. 56 FR 56694 and 57 FR 56762.

The Kent and Queen Anne's Counties area, which was designated

unclassifiable/attainment prior to enactment, was redesignated to

nonattainment and classified as marginal. The Counties of Allegany,

Caroline, Dorchester, Garrett, St. Mary's, Somerset, Talbot,

Washington, Wicomico, and Worcester retained their unclassifiable/

attainment designations. Under the pre-amended Act, these areas were

not required to meet the RACT requirement for nonattainment areas.

The entire State of Maryland, including Kent, Queen Anne's,

Allegany, Caroline, Dorchester, Garrett, St. Mary's, Somerset, Talbot,

Washington, Wicomico, and Worcester Counties, is located in the ozone

transport region (OTR) that was statutorily created by section 184 of

the Act. As such, Maryland was required to adopt RACT rules for all CTG

and non-CTG sources throughout the State by November 15, 1992.

Therefore, under the RACT Catch-up provision of section 182(b)(2),

Maryland was required to submit RACT rules for Kent, Queen Anne's,

Allegany, Caroline, Dorchester, Garrett, St. Mary's, Somerset, Talbot,

Washington, Wicomico, and Worcester Counties covering all pre-enactment

CTGs, to identify all sources the State anticipates will be covered by

a post-enactment CTG and to submit non-CTG rules for all remaining

major sources having the potential to emit 50 TPY of VOC or more.

In summary, to fully comply with the RACT Catch-up provisions of

the Act, Maryland is required to expand its RACT regulations to

statewide. It must adopt all RACT regulations for all CTG sources and

all major non-CTG VOC sources (VOC sources with the potential to emit

25 TPY in Cecil County and the Baltimore nonattainment area

and 50 TPY in the remainder of the State) throughout the

State. Sources must comply with these provisions as expeditiously as

possible, but no later than May 15, 1993.

State Submittals

On April 5, 1991, September 20, 1991, April 2, 1992, January 18,

1993, June 8, 1993 and July 19, 1993, Maryland submitted SIP revisions

to address the RACT fix-up requirement. Portions of Maryland's June 8,

1993 and July 19, 1993 submittals also address the RACT Catch-up

requirement.

EPA proposed approval of portions of Maryland's April 5, 1991

submittal on September 27, 1993 (58 FR 50307). EPA proposed approval of

portions of Maryland's September 20, 1991, April 2, 1992 and January

18, 1993 submittals on and September 30, 1993 (58 FR 51028). Final

action on this proposal was taken on September 7, 1994 (59 FR 46180).

EPA proposed approval of one regulation contained in these submittals,

Standards for Adhesive Application, on February 16, 1993 (58 FR 8565).

Final action on this regulation was taken on November 30, 1993 (58 FR

63085).

The portions of Maryland's April 5, 1991, April 2, 1992, January

18, 1993 June 8, 1993, and July 19, 1993 submittals pertaining to

Maryland's Stage I (COMAR 26.11.13.04) regulation are addressed in this

rulemaking action. Maryland's September 20, 1991 submittal did not

include any revisions to Stage I. This rulemaking action also addresses

revisions to Maryland's VOC RACT regulations, COMAR 26.11.11.02,

26.11.11.04, 26.11.13.01, 26.11.13.02, 26.11.13.07, 26.11.19.01,

26.11.19.02A, F and H, and 26.11.19.10, submitted on June 8, 1993 and

July 19, 1993.

Maryland's April 5, 1991, June 8, 1993 and July 19, 1993 submittals

also contain revisions to Maryland's generic VOC RACT and minor source

[[Page 2020]] regulations, COMAR 26.11.19.02G and 26.11.06.06A and B,

respectively. Revisions to COMAR 26.11.19.02G and 26.11.06.06A and B

are the subject of a separate rulemaking action.

II. EPA Evaluation and Action

VOCs contribute to the production of ground level ozone and smog.

These rules were adopted as part of an effort to achieve the National

Ambient Air Quality Standard (NAAQS) for ozone. The following is EPA's

evaluation and action for the State of Maryland. Detailed descriptions

of the amendments addressed in this document, and EPA's evaluation of

the amendments, are contained in the technical support document (TSD)

prepared for these revisions. Copies of the TSD are available from the

EPA Regional office listed in the ADDRESSES section of this document.

RACT Catch-up Requirements

Because Maryland is in the OTR, the entire State is subject to the

RACT Catch-up provisions of section 182(b)(2) of the Act. Therefore,

Maryland is required to (1) adopt statewide RACT rules covering all

pre-enactment CTGs, (2) identify all sources the State anticipates will

be covered by a post-enactment CTG and (3) submit non-CTG rules for all

remaining major sources. The Baltimore and Philadelphia nonattainment

areas are classified as severe. Therefore a major source in these areas

is a source having the potential to emit 25 TPY of VOC or more. In the

remainder of the State, a major source is defined as a source having

the potential to emit 50 TPY of VOC or more.

State Submittal

Maryland had previously adopted all applicable Group I, II, and III

CTGs. On February 22, 1993, Maryland submitted a negative declaration

letter to EPA indicating that Maryland has no sources covered by the

CTGs which Maryland has not adopted. Through the following revisions,

Maryland has expanded the applicability of its CTG regulations to

statewide and lowered the major source threshold for non-CTG RACT.

(1) Maryland revised the applicability of its VOC stationary source

regulations, COMAR 26.11.11.02 (Asphalt Paving), COMAR 26.11.11.04

(Petroleum Refineries), COMAR 26.11.13 (Control of Gasoline and

Volatile Organic Compound Storage and Handling), and COMAR 26.11.19

(Volatile Organic Compounds from Specific Processes), to statewide.

Under COMAR 26.11.11, sources in the newly regulated areas must comply

by the effective date of the regulation, April 26, 1993. Under COMAR

26.11.13 and the category-specific regulations in COMAR 26.11.19,

sources in Maryland's newly regulated areas must comply as

expeditiously as possible, but no later than May 15, 1993. Sources in

Maryland's pre-enactment nonattainment areas must already be in

compliance with COMAR 26.11.11, 26.11.13, and 26.11.19.

(2) Maryland also added a definition for the term ``major

stationary source of VOC'' (COMAR 26.11.19.01B(4)) to its VOC

regulations. This term means any stationary source with the potential

to emit (a) 25 TPY of VOC or more in the City of Baltimore and Anne

Arundel, Baltimore, Carroll, Cecil, Harford, and Howard Counties and

(b) 50 TPY in the remainder of the State.

(3) Finally, Maryland changed the applicability threshold for COMAR

26.11.19.10: Graphic Arts, from 550 pounds per day (100 TPY) to the

major source threshold defined in COMAR 26.11.19.01B(4).

EPA's Evaluation

The revisions listed above are approvable as SIP revisions because

they comply with the RACT Catch-up requirements of the Act. Through

these revisions, Maryland has met the first major Catch-up requirement,

which was to adopt statewide RACT rules covering all pre-enactment

CTGs.

The remaining requirements, (1) to identify all sources the State

anticipates will be covered by a post-enactment CTG and (2) to submit

non-CTG rules for all remaining major sources, are addressed through

Maryland's generic VOC RACT regulation, COMAR 26.11.19.02G. Revisions

to COMAR 26.11.19.02G are the subject of a separate rulemaking action.

RACT Fix-up Requirements

Maryland was required to correct deficiencies in existing VOC RACT

regulations applicable in pre-enactment nonattainment areas. EPA

identified deficiencies in Maryland's Stage I regulation, COMAR

26.11.13.04, in a June 14, 1988 letter to Maryland which followed EPA's

SIP Call. In order to correct the identified deficiencies, Maryland

must revise its Stage I regulation to conform to EPA guidance,

including the Stage I CTG and model rules.

Specifically, Maryland is required to revise its Stage I bulk

terminal regulation to require vapor control systems to collect all

vapors from its loading racks and destroy at least 90% of these vapors.

Maryland is required to adopt a bulk gasoline plant regulation which

conforms with EPA policy. Additionally, Maryland is required to revise

its Stage I small storage tank regulation to require that all tanks

installed prior to January 1, 1979 with a 2000 gallon capacity or

greater and all tanks constructed after December 31, 1978 with a 250

gallon capacity or greater be equipped with a vapor control system.

State Submittal

Maryland revised its regulation, COMAR 26.11.13.04: Control of

Gasoline and VOC Storage--Loading Operations (A. Bulk Terminals, B.

Bulk Plants, C. Small Storage Tanks, and D. General Requirements), to

respond to the requirements listed above. Additionally, Maryland

expanded the applicability of this regulation to statewide. Maryland

also made a minor revision to its definition of the term ``bulk

gasoline plant'' (COMAR 26.11.13.01B(1)), for clarification.

A. Bulk Terminals

Maryland's Stage I bulk gasoline terminal regulation, which covers

facilities with daily gasoline throughput greater than 20,000, now

requires vapor control systems at loading racks to collect all vapors

and destroy at least 90% of these vapors.

B. Bulk Plants

Maryland's bulk gasoline plant regulates facilities with daily

gasoline throughput between 4,000 gallons and 20,000 gallons. This

regulation conforms with EPA's model rule requiring vapor balance

systems and top submerged or bottom loading systems. This regulation

also prohibits the transfer of gasoline into a storage tank unless

Stage I is properly used and requires that the vapor control system be

leak tight.

C. Small Storage Tanks

Maryland revised the capacity limits in Maryland's small storage

tank Stage I regulation. The new capacity cutoffs are 250 gallons for

``new'' tanks constructed after May 8, 1991 and 2,000 gallons for

``old'' tanks constructed before May 8, 1991.

D. General Requirements

This section prohibits the loading of VOC or gasoline into a tank

truck, railroad car, or other contrivance unless the loading

connections on the vapor lines are equipped with leak tight fittings

which automatically close upon disconnection, and the equipment is

maintained and operated to prevent avoidable liquid leaks during

loading and unloading. [[Page 2021]]

EPA's Evaluation

These revisions are approvable because they correct deficiencies in

Maryland's existing Stage I regulation and expand the applicability to

statewide to conform with the RACT Fix-up and Catch-up requirements of

the Act. These regulations now conform to EPA guidance.

In COMAR 26.11.13.04C, Small Storage Tanks, Maryland's use of an

alternative date (May 8, 1991 instead of January 1, 1979) to

distinguish between new and old storage tanks is acceptable because it

conforms with the spirit of EPA's guidance. The January 1, 1979 date

was used in the Stage I model rule found in EPA's April 1978 document,

``Regulatory Guidance for the Control of Volatile Organic Compound

Emissions from 15 Categories of Stationary Sources,'' to grandfather

existing tanks in newly regulated areas. Maryland used the May 8, 1991

because that was the effective date of the first amendments to this

regulation made to comply with the RACT Fix-up requirements.

EPA is approving these SIP revisions without prior proposal because

the Agency views them as noncontroversial amendments and anticipates no

adverse comments. However, in a separate document in this Federal

Register publication, EPA is proposing to approve the SIP revisions

should adverse or critical comments be filed. This action will be

effective on March 7, 1995 unless, within 30 days of publication,

adverse or critical comments are received.

If EPA receives such comments, this action will be withdrawn before

the effective date by publishing a subsequent notice 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 March 7, 1995.

As required by 40 CFR 51.102, the State of Maryland has certified

that public hearings with regard to these revisions were held in

Maryland on September 30, 1986 in Baltimore; on October 11, 1990 in

Annapolis; on November 25, 1991 in Baltimore; on November 17, 18, and

20, 1992 in Frederick, Centreville, and Columbia, respectively; and on

June 8, 1993 in Baltimore.

Final Action

Because these revisions comply with the RACT Fix-up and Catch-up

requirements of section 182 of the Act, EPA is approving the amendments

to Maryland's VOC RACT regulations, including Stage I. Specifically,

EPA is approving amendments to COMAR 26.11.11.02, 26.11.11.04,

26.11.13.01, 26.11.13.02, 26.11.13.04, 26.11.13.07, 26.11.19.01,

26.11.19.02A, F and H, and 26.11.19.10. These revisions were submitted

to EPA by the State of Maryland as SIP revisions on April 5, 1991,

April 2, 1992, January 18, 1993, June 8, 1993, and July 19, 1993.

Nothing in this action should be construed as permitting or

allowing or establishing a precedent for any future request for

revision to any SIP. Each request for revision to the SIP 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.

SIP approvals under section 110, and subchapter I, Part D of the

Act 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, I certify that it does

not have a significant impact on any small entities affected. Moreover,

due to the nature of the federal-state relationship under the Act,

preparation of a flexibility analysis would constitute federal inquiry

into the economic reasonableness of State action. The Act forbids EPA

to base its actions concerning SIPs on such grounds. Union Electric Co.

v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).

This action has been classified as a Table 2 action for signature

by the Regional Administrator under the procedures published in the

Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by

an October 4, 1993 memorandum from Michael H. Shapiro, Acting Assistant

Administrator for Air and Radiation. The 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 March 7, 1995. 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 action may not be challenged later in proceedings

to enforce its requirements. (See section 307(b)(2).)

The Regional Administrator's decision to approve or disapprove the

SIP revision, pertaining to Maryland's VOC RACT Catch-ups and Stage I

Vapor Recovery, will be based on whether it meets the requirements of

section 110(a)(2)(A)-(K), and Part D of the Clean Air Act, as amended,

and EPA regulations in 40 CFR Part 51.
