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

**ACTION :**  Proposed rule: corrections, extension of the comment period, and additional public hearings.

**SUMMARY :**  On June 21, 2010, EPA proposed to regulate the disposal of coal combustion residuals generated from the combustion of coal at electric utilities and by independent power producers. This action makes several administrative corrections in the preamble to the proposed rule, which were discovered after the proposal was published in the Federal Register . In addition, EPA is providing notice that additional support documents are available for public inspection in the rulemaking docket.

This action also extends the deadline for submitting written comments on the proposed rule to November 19, 2010. This extension provides an additional 60 days for the public to provide written comments. EPA received numerous requests for an extension of the comment period and this notice is the Agency’s response to those persons who requested an extension of the comment period.

Also, in response to significant public interest in the proposed rule, the Agency recently announced on its Web site that it will conduct two additional public hearings on the proposed rule, one in Pittsburgh, Pennsylvania, and the other in Louisville, Kentucky, and an additional Webinar. Additional information on these announcements is included in this notice.

**SUPPLEMENTARY INFORMATION :**  A. Background on the Proposed Rule

On June 21, 2010, EPA co-proposed two options for regulating the disposal of coal combustion residuals (CCRs), commonly known as coal ash, generated from the combustion of coal at electric utilities and by independent power producers (75 FR 35128). Under the first proposal, EPA would reverse its August 1993 and May 2000 Bevill Regulatory Determinations regarding CCRs and list these residuals as special wastes subject to regulation under subtitle C of the Resource Conservation and Recovery Act (RCRA), when they are destined for disposal in landfills and surface impoundments. Under the second proposal, EPA would leave the Bevill Regulatory Determinations in place and regulate the disposal of such materials under subtitle D of RCRA by issuing national minimum criteria. Under both alternatives, EPA proposed not to change the May 2000 Regulatory Determination for beneficially used CCRs, which are currently exempt from the hazardous waste regulations under Section 3001(b)(3)(A) of RCRA.

To assist the reader in reviewing the proposed rule and the corrections published today, EPA has made available an unofficial version of the entire corrected proposal on its Web site, which can be accessed at http:// www.epa.gov/coalashrule.
B. Corrections to the Proposed Rule

The proposed rule as published in the Federal Register on June 21, 2010, contained a number of inadvertent administrative errors in: (1) The

**ADDRESSES** section; (2) a table summarizing EPA’s estimates of regulatory costs and benefits; (3) the discussion of EPA’s risk assessment; and (4) a footnote. Accordingly, the June 21, 2010 publication of the proposed rule is corrected as follows:

1. On page 35128, second column, sixth paragraph, in the first sentence,

‘‘Mailcode: 5305T, ’’ is corrected to read

‘‘Mailcode: 28221T, ’’

.

2. On page 35134, Table 1 is replaced with the following table.

C. Notice That Additional Support Documents Have been Placed in the Docket

This document also notifies the public that EPA has included additional support documents in the proposed rule docket. Documents that were referenced in the proposed rule, and were previously found only on EPA’s Coal Combustion Products Partnership (C2P2) Web site have been moved to the docket for this rulemaking. Similarly, EPA has included in the docket a notice that describes a file transfer protocol (FTP) site where the public can download the full scale risk modeling input and output files used in the document entitled, ‘‘Draft Human and Ecological Risk Assessment of Coal Combustion Wastes, ’’ April, 2010. EPA also has added the executable files for the models used in the risk assessment in the same FTP site. As part of the proposed rule, EPA had stated that these materials would be available upon request; in the interest of ensuring the greatest degree of public access, EPA has subsequently decided to place them in the rulemaking docket.

EPA therefore recommends that the public consult the docket to access all of EPA’s record support documents. The docket provides the date on which the material was added, so newly added materials will be easily identifiable.
D. Two Additional Public Hearings

On July 15, 2010 (75 FR 41121), EPA announced in the Federal Register its intent to conduct five public hearings across the United States to allow the public an opportunity to present data, views or arguments concerning the proposed rule. These public hearings are scheduled to take place in Arlington, Virginia; Denver, Colorado; Dallas, Texas; Charlotte, North Carolina; and Chicago, Illinois. Given the significant public interest in this rule and to further public participation opportunities, on August 6, 2010, EPA announced on its website that it would hold two additional public hearings, one in Pittsburgh, Pennsylvania, on September 21, 2010, and the other in Louisville, Kentucky, on September 28, 2010. These public hearings will be conducted in the same manner as the public hearings announced in the July 15, 2010, Federal Register notice. Details on the Pittsburgh and Louisville public hearings can be found on EPA’s Web site at: http://www.epa.gov/epawaste/nonhaz/industrial/special/fossil/ccrrule/ccr-hearing.htm. If you have any questions, please contact either Bonnie Robinson or Elaine Eby at the addresses given above under **FOR FURTHER**
**INFORMATION CONTACT**

. E. Additional Webinar EPA previously announced that the Agency will be hosting two Webinars; one on August 5, 2010, and a second on August 12, 2010. On August 6, 2010, EPA announced on its Web site that we would conduct an additional Webinar. As soon as the scope and format of the third Webinar is determined, EPA will post such information on the Web site: http://www.epa.gov/osw/nonhaz/industrial/special/fossil/ccr-rule/ccrwebinar.htm. EPA will post the transcript from the Webinars on its Web site and will put into the rulemaking record the questions that we receive during the Webinars. However, the Webinars are designed to assist the public in understanding the proposal and are not designed to take public comment on the proposal. For example, many of the questions that were submitted appear to have been made in response to statements made as part of the presentation, and may not be entirely clear without that context. Consequently, although EPA will treat the questions submitted during the Webinar as part of the rulemaking record, (and will respond accordingly), EPA encourages those who submitted questions as part of the Webinar, and who wish to submit comments on the proposal, to consider whether they wish to supplement or clarify those questions, and to follow the procedures for submitting comments set out in this notice and in our June 21 proposal.

Dated: August 12, 2010. Mathy Stanislaus, Assistant Administrator, Office of Solid Waste and Emergency Response.
