**SUPPLEMENTARY INFORMATION:** On October 24, 2007, the Maryland
Department of Environment (MDE) submitted a revision to its SIP to
establish RACT requirements for marine vessel and barge loading. The SIP
revision (Maryland SIP #07-12) consists of 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.

**I. Background**

This SIP revision was submitted pursuant to the reasonable available
control technology requirements of sections 182 and 184 of the Clean Air
Act. RACT is 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.
Maryland is located in the Ozone Transport Region (OTR) that was
statutorily created by section 184 of the CAA. Section 184(b)(1)(B) of
the CAA requires States to implement RACT regulations on all VOC sources
that have the potential to emit 50 tons per year (TPY) or more. In
addition, section 182(b)(2) requires States to implement RACT
regulations on all "major" sources of VOC in moderate or above ozone
nonattainment areas. 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.\
Maryland is in the OTR and the State is required to implement RACT
regulations for all sources with the potential to emit 50 TPY or more,
throughout the State. In Maryland\'s severe ozone nonattainment areas,
RACT is required for all VOC sources with the potential to emit 25 TPY
or more.

The amendment to Regulation .01 and adoption of new Regulation .08 under
COMAR 26.11.13 control emissions of volatile organic compounds
throughout the state. MDE submitted this SIP revision request pursuant
to the reasonable available control technology requirements of sections
182 and 184 of the Clean Air Act. Although the EPA has developed a
maximum achievable control technology standard for barge loading (40 CFR
Part 63 Subpart Y), the liquid throughput threshold requiring controls
is very high. For this reason, MDE has adopted RACT requirements for
marine vessel and barge loading.

A marine vessel is defined as any tank ship or barge that transports
VOCs in bulk as cargo. Marine tank vessel loading operations are
facilities that load and unload liquid commodities in bulk. Due to the
increased demand for ethanol which is blended with gasoline, there is a
renewed interest in transferring liquid products from stationary storage
tanks into marine vessels or barges for further distribution. During
marine tank vessel and barge loading operations, emissions result as the
liquid that is being loaded into the vessel displaces vapors from the
vessel\'s tank. VOC vapors are released from the vent of the barge in
quantities that may be significant and contribute to ground level ozone.
Maryland has decided to revise their RACT requirements to include marine
vessel and barge loading.

**II. Summary of SIP Revision**

The Maryland Department of the Environment is requesting a revision to
the state's SIP to establish reasonable available control technology
requirements for marine vessel and barging loading. The amendment to
COMAR 26.11.13.01 consist 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 or 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
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.

**III. Proposed Action**

EPA is proposing to approve the Maryland SIP revision for the
establishment of RACT requirements to control VOC emissions from marine
vessel and barging loading, which the state submitted on October 24,
2007. EPA is soliciting public comments on the issues discussed in this
document. These comments will be considered before taking final action.

**IV. Statutory and Executive Order Reviews**

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 proposes to approve state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this proposed 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 proposed rule to approve Maryland's amendments to the
control of volatile organic compound emissions by establishing
reasonable available control technology requirements for marine vessel
and barge loading 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.
