**SUPPLEMENTARY INFORMATION**:

**I. Background**

On April 15, 2008 (73 FR 20234), EPA published a notice of proposed
rulemaking (NPR) for the State of Maryland. The NPR proposed approval of
the control of VOC emissions from marine vessel and barge loading by
establishing RACT requirements. The formal SIP revision was submitted by
the Maryland Department of the Environment (MDE) on October 24, 2007.

**II. Summary of SIP Revision**

The Maryland Department of the Environment submitted this revision to
the SIP to establish reasonably available control technology
requirements for marine vessel and barging loading. The SIP revision
includes amendments to Regulation .01 and adoption of new Regulation .08
under COMAR 26.11.13 Control of Gasoline and Volatile Organic Compound
Storage and Handling. The amendment to COMAR 26.11.13.01 consists of a
new definition that defines a marine vessel as any tank ship or barge
that transports VOCs in bulk as cargo. The new regulation COMAR
26.11.13.08 requires owners or operators of barge loading facilities in
Baltimore City, Anne Arundel, Baltimore, Calvert, Carroll, Cecil,
Charles, Frederick, Harford, Howard, Montgomery, and Prince George's
Counties to reduce capture of VOC vapors by 90 percent if emissions from
the barge loading equal or exceed 25 tons per year (TPY). In the rest of
the state (Allegheny, Caroline, Dorchester, Garrett, Kent, Queen Anne's,
St. Mary's, Somerset, Talbot, Washington, Wicomico, and Worchester
Counties), controls are required if emissions are equal to or exceed 50
TPY.

The rationale for EPA\'s proposed action are explained in the NPR and
will not be restated here. On April 15, 2008, EPA received a comment on
the April 15, 2008 NPR. A summary of the comment submitted and EPA=s
response is provided in Section III of this document.

**III. Summary of Public Comments and EPA Response**

**Comment:** A single commenter questions why the state is establishing
a RACT standard for marine vessel and barge loading instead of a Best
Available Control Technology (BACT) or Maximum Achievable Control
Technology (MACT) standard. The commenter also claims that established
BACT and MACT standards would achieve greater control than the proposed
RACT standard, though at cost ranging from somewhat less than estimated
by the state.

**Response:** These amendments, submitted by the State of Maryland
establishing RACT requirements for VOC emissions from marine vessel and
barge loading, are being approved by EPA because EPA has determined that
they properly represent RACT for this source category. Since the
1970\'s, EPA has consistently interpreted RACT to mean the lowest
emission limit that a particular source is capable of meeting by the
application of the control technology that is reasonably available
considering technological and economic feasibility. [See]{.underline},
[e.g.]{.underline}, 72 FR 20586 at 20610 (April 25, 2007). Maryland
submitted this SIP revision request pursuant to the RACT requirements of
sections 182 and 184 of the CAA. Other provisions of the CAA may require
BACT or MACT level controls for sources. However, these are generally
considered to be more stringent than RACT, and thus, the controls
necessary to meet BACT or MACT requirements may not be the same as
controls that would meet the RACT requirement.

Maryland is located in the Ozone Transport Region (OTR) that was created
by section 184 of the CAA. Section 184(b)(1)(B) of the CAA requires that
Maryland implement RACT regulations on all VOC sources that have the
potential to emit 50 TPY or more. In addition, section 182(b)(2)
requires that Maryland implement RACT regulations on all major sources
of VOC in moderate or above ozone nonattainment areas within the State.
Major VOC sources are those with the potential to emit at least 100 TPY
in moderate areas, 50 TPY in serious areas, and 25 TPY in severe areas.

BACT, on the other hand, is a case-by-case emissions limitation based on
the maximum degree of reduction of a regulated pollutant emitted from a
major new source or a major modification of an existing source, as
determined by application of EPA's Prevention of Significant
Deterioration regulations, 40 C.F.R. 52.21, which are authorized by
Sections 160 -- 169 of the CAA. BACT, therefore, is determined by a
different standard than RACT and does not apply to unmodified existing
sources that would be covered by the RACT rule.

Similarly, MACT is also a distinct legal requirement and is determined
through a different standard than RACT. MACT standards are designed to
reduce hazardous air pollutants emissions to a maximum achievable
degree, taking into account factors such as cost and energy
requirements, as set forth at 40 CFR 63.41, and as authorized by section
112 of the CAA. Although EPA has promulgated a standard for barge
loading (40 CFR Part 63 Subpart Y), as with BACT, not every source
required to be covered by the Maryland RACT rule would be required to
have a MACT limit, and the definition of MACT takes into account factors
that are not required for RACT.

In sum, RACT, MACT, and BACT are potentially overlapping emissions
limitation requirements, authorized by different provisions of the CAA,
directed to remedy distinct problems (RACT, in this case, to help attain
the federal ozone standard by controlling emissions of VOC, an ozone
precursor; BACT to prevent significant deterioration in areas attaining
a federal standard through permitting of new and modified sources; and
MACT to control emissions of listed hazardous air pollutants), covering
different (but potentially overlapping) subsets of sources, and based on
different control standards.

The commenter\'s failure to document and support either cost data
provided in the comment, or the methodology the commenter used to
determine BACT/MACT, prevents EPA from ascertaining whether or not the
commenter has properly determined BACT/MACT for these operations, the
relative costs compared to the RACT adopted by the State, where the cost
data supplied in the comment comes from, or if it is valid. Mere
assertions, without analysis, that EPA\'s proposal is wrong are an
insufficient basis for EPA to disapprove this SIP. See *International
Fabricare Inst. v. EPA,* 972 F.2d 384 (D.C.Cir. 1992).

EPA has evaluated Maryland's SIP submittal and determined that the
Maryland regulation meets the requirements for RACT. Because this SIP
revision meets the criteria for RACT, as well as the other approvability
criteria, EPA must approve this SIP revision. [SeeNumber range
CHAPTER]{.underline} section 110(k)(3) of the CAA, 42 U.S.C. 7410(k)(3);
[see]{.underline} [also]{.underline}, [Union Elec. Co. v.
EPA,]{.underline} 427 U.S. 246, 265, 96 S.Ct. 2518, 49 L.Ed.2d 474
(1976).

**III. Final Action**

EPA is approving the control of volatile organic compound emissions by
establishing reasonably available control technology requirements for
marine vessel and barge loading as a revision to the Maryland SIP which
was submitted on October 24, 2007. This regulation will result in the
reduction of VOC emissions from the affected sources.

**IV. Statutory and Executive Order Reviews**

**A. General Requirements**

Under the Clean Air Act, the Administrator is required to approve a SIP
submission that complies with the provisions of the Act and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve state choices,
provided that they meet the criteria of the Clean Air Act. Accordingly,
this action merely approves state law as meeting Federal requirements
and does not impose additional requirements beyond those imposed by
state law. For that reason, this action:

-   is not a \"significant regulatory action" subject to review by the
    Office of Management and Budget under Executive Order 12866 (58 FR
    51735, October 4, 1993);

-   does not impose an information collection burden under the
    provisions of the Paperwork Reduction Act (44 U.S.C. 3501 [et
    seq]{.underline}*.*);

-   is certified as not having a significant economic impact on a
    substantial number of small entities under the Regulatory
    Flexibility Act (5 U.S.C. 601 [et seq]{.underline}.);

-   does not contain any unfunded mandate or significantly or uniquely
    affect small governments, as described in the Unfunded Mandates
    Reform Act of 1995 (Public Law 104-4);

-   does not have Federalism implications as specified in Executive
    Order 13132 (64 FR 43255, August 10, 1999);

-   is not an economically significant regulatory action based on health
    or safety risks subject to Executive Order 13045 (62 FR 19885, April
    23, 1997);

-   is not a significant regulatory action subject to Executive Order
    13211 (66 FR 28355, May 22, 2001);

-   is not subject to requirements of Section 12(d) of the National
    Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note)
    because application of those requirements would be inconsistent with
    the Clean Air Act; and

-   does not provide EPA with the discretionary authority to address, as
    appropriate, disproportionate human health or environmental effects,
    using practicable and legally permissible methods, under Executive
    Order 12898 (59 FR 7629, February 16, 1994).

In addition, this rule does not have tribal implications as specified by
Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP
is not approved to apply in Indian country located in the state, and EPA
notes that it will not impose substantial direct costs on tribal
governments or preempt tribal law.

**B. Submission to Congress and the Comptroller General**

The Congressional Review Act, 5 U.S.C. 801 [et seq]{.underline}., as
added by the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of the Congress and to the Comptroller
General of the United States. EPA will submit a report containing this
action and other required information to the U.S. Senate, the U.S. House
of Representatives, and the Comptroller General of the United States
prior to publication of the rule in the [Federal]{.underline}
[Register]{.underline}. A major rule cannot take effect until 60 days
after it is published in the [Federal]{.underline}
[Register]{.underline}. This action is not a "major rule" as defined by
5 U.S.C. 804(2).

**C. Petitions for Judicial 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 \[[Insert date 60 days from date
of publication of this document in the Federal Register]{.underline}\].
Filing a petition for reconsideration by the Administrator of this final
rule does not affect the finality of this action 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 pertaining to Maryland's amendments
to the control of volatile organic compound emissions by establishing
RACT requirements for marine vessel and barge loading may not be
challenged later in proceedings to enforce its requirements. (See
section 307(b)(2).)
