**Revisions to the California State Implementation Plan, Antelope Valley**  **Air Quality Management District and Imperial Valley Air Pollution Control**  **District**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule. **SUMMARY :**  EPA is proposing to approve revisions to the Antelope Valley Air Quality Management District (AVAQMD) and Imperial County Air Pollution Control District (ICAPCD) portions of the California State Implementation Plan (SIP). These revisions concern oxides of nitrogen (NO X) emissions from stationary gas turbines. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

**DATES :**  Any comments on this proposal must arrive by February 17, 2012.

**ADDRESSES :**  Submit comments, identified by docket number EPA–R09– OAR–2011–0987, by one of the following methods: 1. Federal eRulemaking Portal: www.regulations.gov. Follow the on-line instructions.

2. Email: steckel.andrew@epa.gov. 3. Mail or deliver: Andrew Steckel (Air-4), U.S. Environmental Protection Agency Region IX, 75 Hawthorne Street, San Francisco, CA 94105–3901.

Instructions: All comments will be included in the public docket without change and may be made available online at www.regulations.gov

, including any personal information provided, unless the comment includes Confidential Business Information (CBI) or other information whose disclosure is restricted by statute.

www.regulations.gov is an ‘‘anonymous access’’ system, and EPA will not know your identity or contact information unless you provide it in the body of your comment. If you send email directly to EPA, your email address will be automatically captured and included as part of the public comment. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment. Electronic files should avoid the use of special characters, any form of encryption, and be free of any defects or viruses.

Docket: Generally, documents in the docket for this action are available electronically at www.regulations.gov and in hard copy at EPA Region IX, 75 Hawthorne Street, San Francisco, California. While all documents in the docket are listed at www.regulations.gov, some information may be publicly available only at the hard copy location (e.g., copyrighted material, large maps), and some may not be publicly available in either location ( e.g., CBI). To inspect the hard copy materials, please schedule an appointment during normal business hours with the contact listed in the **FOR FURTHER INFORMATION CONTACT**  section.

**FOR FURTHER INFORMATION CONTACT :**  Idalia Perez, EPA Region IX, (415) 972– 3248, perez.idalia@epa.gov.

**SUPPLEMENTARY INFORMATION :**  This proposal addresses the following local rules: AVAQMD Rule 1134, Stationary Gas Turbines and ICAPCD Rule 400.1, Stationary Gas Turbine(s)—Reasonably Available Control Technology (RACT). In the Rules and Regulations section of this Federal Register , we are approving these local rules in a direct final action without prior proposal because we believe these SIP revisions are not controversial. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in subsequent action based on this proposed rule. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment.

We do not plan to open a second comment period, so anyone interested in commenting should do so at this time. If we do not receive adverse comments, no further activity is planned. For further information, please see the direct final action. Dated: December 27, 2011. Jared Blumenfeld, Regional Administrator, Region IX.

**RIN 2060–XXXX**
**Great Lakes Steamship Repower Incentive Program** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Notice of proposed rulemaking.

**SUMMARY :**  EPA is proposing to simplify an existing provision in our marine diesel engine program that is intended to encourage owners of Great Lakes steamships to repower those steamships with cleaner marine diesel engines. The simplified program would automatically permit the use of residual fuel, through December 31, 2025, in a steamship if it has been repowered with a certified Tier 2 or later marine diesel engine, provided the steamship was operated exclusively on the Great Lakes and was in service on October 30, 2009. Steamships are powered by old, inefficient steam boilers. Voluntary replacement of these boilers with modern fuel-efficient marine diesel engines would result in reductions of particulate matter and sulfur oxides, even while the replacement diesel engines are operated on higher sulfur residual fuel, and would provide human health and welfare benefits for the people who live in the Great Lakes region. Conversion to new diesel engines would also result in considerable carbon dioxide reductions and fuel savings. In the ‘‘Rules and Regulations’’ section of this Federal Register , we are making this modification to the Great Lakes steamship incentive program as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.

**DATES :**  Written comments must be received by February 17, 2012.

**ADDRESSES :**  Submit your comments, identified by Docket ID No. EPA–HQ– OAR–2011–0928, by mail to: Environmental Protection Agency, Air Docket, Mail-code 6102T, 1200 Pennsylvania Avenue NW., Washington, DC 20460. Comments may also be submitted electronically or through hand delivery/courier by following the detailed instructions in the **ADDRESSES** section of the direct final rule located in the rules section of this Federal Register

.

Public Hearing: If anyone contacts us requesting to speak at a public hearing on or before February 2, 2012, we will hold a public hearing. Additional information about the hearing would be published in a subsequent Federal Register notice.

**SUPPLEMENTARY INFORMATION :**  I. Why is EPA issuing this proposed rule?

This document proposes to take action on our national marine diesel emission control program. We have published a direct final rule to simplify our Great Lakes steamship repower incentive program in the ‘‘Rules and Regulations’’ section of this Federal Register because we view this as a noncontroversial action and anticipate no adverse comment. We have explained our reasons for this action in the preamble to the direct final rule.

If we receive no adverse comment, we will not take further action on this proposed rule. If we receive adverse comment, we will withdraw the direct final rule and it will not take effect. We would address all public comments in any subsequent final rule based on this proposed rule.

We do not intend to institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information, please see the **ADDRESSES** section of this document. II. Does this action apply to me?

This action will affect companies that own steamships operating exclusively on the Great Lakes that were in service on October 30, 2009. The following table gives some examples of entities that may be affected by this rule; however, since these are only examples, you should carefully examine the regulations. You may direct questions regarding the applicability of this action as noted in **FOR FURTHER INFORMATION CONTACT**
