# ACTION:

Final rule.

# SUMMARY:

This document announces that the Environmental Protection Agency (EPA) is taking final action approving revisions to the Rhode Island State Implementation Plan (SIP) submitted by Rhode Island Department of Environmental Management (RI DEM) Office of Air Resources, on January 18, 2011. The EPA finds that RI DEM has satisfied all the elements of our October 24, 2013, final conditional approval, and as such, the conditional approval is converting to a full approval with this action. The commitment consisted of a submission by Rhode Island of a technical demonstration, that Rhode Island's PSD and nonattainment new source review permitting programs are at least as stringent in all respects as EPA's NSR Reform provisions for stationary sources of regulated NSR pollutants other than Greenhouse Gases (GHGs). This action is being taken under section 110 of the Act.

# DATES:

This rule is effective April 21, 2015.

V. Final Action

## I. Background

On October 24, 2013, EPA conditionally approved, pending submission by Rhode Island of a technical demonstration that Rhode Island's January 18, 2011 SIP revisions as they relate to major new and modified stationary sources of regulated NSR pollutants other than GHGs, are as least as stringent as EPA's NSR reform. See 78 FR 63383. On February 27, 2015, the State Rhode Island submitted a technical demonstration, pursuant to 40 CFR 51.166(a)(7), that Rhode Island's PSD and nonattainment new source review permitting programs are at least as stringent in all respects as EPA's NSR Reform provisions for stationary sources of regulated NSR pollutants other than GHGs.

## II. What is a conditional approval?

                    Under section 110(k)(4) of the Clean Air Act, the EPA may conditionally approve a plan based on a commitment from the State to adopt specific enforceable measures by a date certain no later than one year from the date of final conditional approval. If the EPA subsequently determines that the State has met its commitment, EPA publishes a document in the                     **Federal Register**                     notifying the public that EPA is converting the conditional approval to a full approval. However, if the State fails to timely meet its commitment, then the conditional approval automatically converts to a disapproval by operation of law without further action required by EPA. If that were to occur, EPA would then notify the state by letter. At that time, the conditionally approved SIP revisions would not be part of the state's approved SIP. EPA subsequently would publish a notice in the                     **Federal Register**                     notifying the public that the conditional approval automatically converted to a disapproval.                

## III. What are the terms of the conditional approval?

The EPA conditionally approved Rhode Island's January 18, 2011 SIP revision as it relates to major new and modified stationary sources of regulated NSR pollutants other than GHGs on October 24, 2013. See 78 FR 63383. Our conditional approval was based on a commitment letter submitted by RI DEM on September 18, 2013. Specifically, RI DEM committed to submit a revised technical demonstration (described above) no later than one year from the date on which EPA finalized the conditional approval.

## IV. Were the terms of the conditional approval met?

RI DEM failed to submit the technical demonstration in a timely manner, therefore our conditional approval, by operation of law, became a disapproval on December 23, 2014. However, on February 27, 2015, RI DEM submitted the technical demonstration pursuant to 40 CFR 51.166(a)(7), showing that Rhode Island's PSD and nonattainment new source review permitting programs are at least as stringent in all respects as EPA's NSR Reform provisions for stationary sources of regulated NSR pollutants other than GHGs. Rhode Island's technical demonstration is included in the docket and administrative record for this action.

EPA therefore has determined that RI DEM met the conditions of the conditional approval.

## V. Final Action

EPA is converting the conditional approval to a full approval with this action. Rhode Island's February 27, 2015 submission cured, as a legal matter, the disapproval that automatically occurred on December 23, 2014. Thus, the provisions of Rhode Island's SIP that EPA conditionally approved on October 24, 2013 are now fully approved into the State's SIP.
