I. Background Information

Section 112 of the Clean Air Act (CAA) establishes a two-stage regulatory process to address emissions of hazardous air pollutants (HAP) from stationary sources. In the first stage, after the EPA has identified categories of Start Printed Page 42053sources emitting one or more of the HAP listed in section 112(b) of the CAA, section 112(d) calls for the Administrator to promulgate national emission standards for hazardous air pollutants for those sources. The EPA is then required to review these technology-based standards, and to revise them “as necessary (taking into account developments in practices, processes, and control technologies)” no less frequently than every 8 years, under CAA section 112(d)(6). The second stage in standard-setting focuses on reducing any remaining “residual” risk according to CAA section 112(f).

On January 16, 2009, then Administrator Stephen Johnson signed a final rule amending the National Emission Standards for Hazardous Air Pollutants From Petroleum Refineries, and the signed rule was made publicly available on the EPA's website. The signed rule included several different actions. First, it promulgated maximum achievable control technology (MACT) standards under CAA sections 112(d)(2) and (3) for heat exchange systems, which the EPA had not addressed in the original Refinery MACT 1 rule (40 CFR part 63, subpart CC). Second, pursuant to CAA section 112(f)(2), the rule addressed residual risk for all Refinery MACT 1 sources, including heat exchange systems. Third, it addressed the technology review pursuant to CAA section 112(d)(6) for all sources addressed in the original Refinery MACT 1 rule. Finally, the rule updated the table in the Refinery MACT 1 standards (Table 6) that cross-references the General Provisions in 40 CFR part 63, subpart A, and made a few additional clarifications to dates and cross-references in the Refinery MACT 1 standards.

The signed rule was submitted to the Office of the Federal Register for publication. Rahm Emanuel, Assistant to the President and Chief of Staff, issued a memorandum on January 20, 2009, directing Agencies to withdraw from the Office of the Federal Register “all proposed or final regulations that have not been published in the Federal Register so that they can be reviewed and approved by a department or agency head.” Although there was an exception for “regulations subject to statutory or judicial deadlines,” the Agency chose not to apply the exception in this case. One portion of the final rule, the CAA section 112(d)(6) review, was performed pursuant to the terms of a Consent Decree, which, as modified, required that by January 16, 2009, the EPA “shall sign and promptly forward to the Federal Register for publication either final revisions to the standards for petroleum refineries in 40 CFR part 63, subpart CC pursuant to 42 U.S.C. 7412(d)(6) or a final determination that no revisions are necessary.” Then Administrator Stephen Johnson signed the rule on January 16, 2009, and promptly forwarded it to the Office of the Federal Register, thus, fulfilling this obligation.[1]

Upon further review, the EPA determined that the residual risk and technology reviews may not accurately characterize the risk posed by this source category. Shortly after the rule was signed, the EPA responded to a Request for Correction under the EPA's Information Quality Guidelines from the city of Houston.[2] In that response, we recognized that we were currently taking action (and planned to take additional action) to gather better emissions information from the refining industry. Additionally, we noted that, during the comment period on the proposed rule, similar issues were raised concerning the representativeness of the emissions data and whether they provided an accurate basis for characterizing the risks posed.

After consideration of the public comments on the proposal to withdraw portions of the final rule, we are providing final notice of the Agency's decision to partially withdraw the final rule. As stated in the preamble to the proposed withdrawal, the EPA will provide the public with an opportunity to comment on any new proposed rule that may be issued addressing the residual risk and technology review requirements of the CAA for this source category.

II. Summary of Comments and Responses

The EPA received a total of six comment letters concerning the proposed partial withdrawal. Comment letters were received from industry trade associations, local environmental organizations, environmental groups, and members of the public. Summaries of the comments and our complete responses are included in the following section.

Comment: Four commenters supported the EPA's proposed partial withdrawal of the Refinery MACT 1 standards signed on January 16, 2009, and supported further analysis leading to a revised set of proposed standards. Several of these commenters asserted that the withdrawal is necessary because the EPA failed to adequately address their comments on the standards that were proposed on September 4, 2007 (72 FR 50716), and November 10, 2008 (73 FR 66694). Some of the comments submitted on those previous proposals and reiterated by the commenters included: (1) Objections to the EPA's interpretation of the CAA requirement that the standards provide an “ample margin of safety”; (2) assertions that the maximum individual lifetime cancer risk allowed by the CAA is 1 in 1 million; (3) objections to the length of time allowed for compliance with standards for storage vessels with floating roofs; (4) identification of multiple deficiencies in the risk assessment methodology, including use of actual emissions rather than allowable emissions and the estimation of emissions at census block centroids rather than property lines; and (5) assertions that the emissions data used in the risk assessment were underestimated and unrepresentative. The commenters requested that the EPA collect more accurate emissions data and re-analyze the residual risk for Refinery MACT 1 using a methodology without the identified deficiencies.

Response: We appreciate the four commenters' support for the withdrawal of the residual risk and technology review portions of the revisions to the Refinery MACT 1 standards. In this notice, the EPA is not making any decisions regarding the scope of residual risk and technology review standards under the CAA or on the specific data that would form the basis for a particular decision. Substantive comments on those issues should be raised in the context of future proposed rules addressing the CAA residual risk and technology review for one or more specific source categories.

Comment: Two commenters objected to the proposed withdrawal of the residual risk and technology review portions of the Refinery MACT 1 standards that were signed on January 16, 2009. These commenters noted that the EPA spent several years collecting data and considering stakeholder comments, finally reaching the conclusion that the Refinery MACT 1 standards provide an ample margin of safety based on data that the EPA judged to be representative of the source category. The commenters asserted that Start Printed Page 42054the docket for the Refinery MACT 1 rulemaking (Docket ID EPA-HQ-OAR-2003-0146) does not include any specific support for the EPA's decision to reject that previous conclusion. According to the commenters, the only support for withdrawing the rule and redoing the analyses is provided in public comments submitted for the proposed rules, and the EPA considered those comments prior to finalizing the rule signed on January 16, 2009. The commenters requested that the EPA present any additional data received or analyses performed since January 16, 2009, to support withdrawal of the standards, and clearly explain any differences in assumptions or methodologies used in the analyses.

One commenter asserted that residual risk and technology review for Refinery MACT 1 has been a time- and resource-consuming process, and due to the EPA's other obligations under the CAA, it is not in the best interest of the public for the EPA to repeat the entire process without good cause. The commenter detailed a number of analyses in the docket showing that the EPA believed its emissions estimates and risk assessment methodologies were appropriate for the rulemaking. The commenter also noted that, if the EPA always postponed regulatory action because data may become available in the future, no regulatory actions would ever be completed. According to the commenter, refiners continue to make improvements in emissions reductions, and the heat exchange system standards will reduce emissions from cooling towers, so further data collection would only serve to support the conclusion that the current standards provide an ample margin of safety.

Two commenters addressed the EPA's responsibilities under the Data Quality Act (DQA) related to the Request for Correction filed by Mayor White of Houston (RFC 02003). The commenters stated that the EPA fulfilled its DQA obligations through its response to Mayor White on April 7, 2009 (Docket Item No. EPA-HQ-OAR-2003-0146-0210), which describes the steps that the EPA plans to take to improve annual emissions estimates. Since the EPA has addressed the DQA concerns raised by Mayor White, the commenters asserted that it is not necessary for the Agency to take action on the proposed withdrawal of the Refinery MACT 1 standards to further address those concerns.

Response: As the commenters noted, we did reach the conclusions presented in the rule that was signed on January 16, 2009, through analysis of the data we had at the time. The commenters are correct that, as of the time of the proposed withdrawal, we had not yet received any specific, additional data to support changing the conclusions reached in the final rule. However, our proposal was not based on the receipt of such information. Our decision to withdraw the residual risk and technology review portions of the January 16, 2009, rule does not mean that we have made a decision to change our conclusions regarding what requirements are necessary and appropriate for the Refinery MACT 1 standards. Instead, as we noted when we proposed the withdrawal, we believe it is necessary to develop a more robust analysis based on the improved information we are in the process of gathering and developing.

With respect to duplicating the “time- and resource-consuming process” associated with the risk and technology review, we note that the EPA is now initiating the risk and technology review for the Refinery MACT 2 standards (40 CFR part 63, subpart UUU) and plans to conduct the Refinery MACT 1 and 2 reviews at the same time. Thus, our data collection efforts for purposes of the Refinery MACT 2 risk and technology review will also provide a significant portion of the information we will need for purposes of our new residual risk and technology review of the Refinery MACT 1 standards. Moreover, we believe that by more closely aligning our risk and technology review for Refinery MACT 1 and 2 sources, we will be able to develop a significantly improved analysis of the risks associated with petroleum refineries, and, therefore, can better determine the most effective way to address any residual risk posed by emissions from petroleum refineries. We see significant benefits in combining these efforts, both in terms of a more transparent risk evaluation of these co-located sources for the neighboring public and in terms of more consolidated standards for the regulated community. The EPA has already taken action to gather better emissions information from the refining industry, and to follow through on the commitments made in the response letter to Mayor White of Houston (Docket Item No. EPA-HQ-OAR-2003-0146-0210). For these reasons, we have concluded that the benefits of a consolidated risk and technology review outweigh the incremental analytical effort required to perform a new risk assessment for Refinery MACT 1 sources after collecting this more robust data.

One commenter suggested that the additional data may lead to the conclusion that the existing standards provide an ample margin of safety. We agree that is a possible outcome; however, any conclusions regarding the residual risk review for the Refinery MACT 1 standards will need to await our consideration of the more robust data we are now gathering. Those data will provide greater certainty for the final conclusions, and help to ensure the final standards are technically and legally defensible.

Finally, the EPA agrees that it has responded to the DQA request from Mayor White of Houston through the April 7, 2009, letter identified by the two commenters (Docket Item No. EPA-HQ-OAR-2003-0146-0210). In that letter, we outlined several initiatives that were either ongoing or planned for the near future in order to improve the quality of data we have concerning emissions from petroleum refineries, and we are continuing to move forward with all of those initiatives. We plan to use this improved information as we move forward to address emissions from petroleum refineries, including performing the residual risk and technology review for Refinery MACT 1 and 2 sources.

Comment: Two commenters noted that, if the EPA proceeds with the proposed partial withdrawal of Refinery MACT 1 standards, the Agency should make clear that the withdrawal completes the action related to the September 4, 2007, proposal. In other words, the commenters stated that the date for determining compliance with any new standards would be the proposal date of those new standards rather than September 4, 2007.

Response: We agree with the commenters. The appropriate dates for determining compliance with future standards would be the dates those standards are proposed and finalized.

Statutory and Executive Order Reviews
