Environmental Protection Agency May 23, 2006 – Federal Register Recent Federal Regulation Documents

EPA is announcing that Versar, Inc., an EPA contractor for external scientific peer review, plans to convene an independent panel of experts and organize and conduct an external peer review meeting to review the draft document titled, ``Harmonization in Interspecies Extrapolation: Use of BW3/4 as Default Method in Derivation of the Oral RfD'' (EPA/630/R-06/001). The peer review meeting is planned to take place by teleconference. On Februrary 15, 2006, EPA announced a 60-day public comment period for the draft document (71 FR 7958). The draft document was prepared by the Agency's Risk Assessment Forum. The public comment period and the external peer review are separate processes that provide opportunities for all interested parties to comment on the document. In addition to considering public comments submitted in accordance with the February 15, 2006, announcement of a public comment period, EPA intends to forward those comments to Versar, Inc. for the external peer review panel prior to the teleconference. EPA is releasing this draft document solely for the purpose of pre- dissemination peer review under applicable information quality guidelines. This document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy or determination. The public will be given an opportunity to observe and provide oral comments at this teleconference by registering with Versar, Inc. (see FOR FURTHER INFORMATION CONTACT, below). The draft document and the charge questions for EPA's external peer review are available primarily via the Internet on the Risk Assessment Forum's home page under the External Review Drafts menu at https://cfpub.epa.gov/ncea/raf/index.cfm. In preparing a final report, EPA will consider Versar Inc.'s report of the comments and recommendations from the external peer review meeting and any public comments that EPA receives in accordance with the February 15, 2006, notice (71 FR 7958).

EPA today, pursuant to section 209(e) of the Clean Air Act (Act), 42 U.S.C. 7543(b), is authorizing California to enforce its regulations setting emission standards and other requirements for large off-road spark-ignition engines.

In compliance with the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), this document announces that EPA is planning to submit a request to renew an existing approved Information Collection Request (ICR) to the Office of Management and Budget (OMB). This ICR is scheduled to expire on November 30, 2006. Before submitting the ICR to OMB for review and approval, EPA is soliciting comments on specific aspects of the proposed information collection as described below.

The EPA is proposing to approve revisions to the Indiana particulate matter (PM10) State Implementation Plan (SIP). On December 15, 2005, Indiana requested revisions for sources at the ASF Keystone, Inc. (Keystone) coil spring manufacturing facility in Lake County, Indiana. The requested revisions will increase the PM10 emission limit for one unit and reduce the limits for two units. The changes result in a net decrease in the allowable emissions. The emission limits for a fourth unit that has shut down are also being removed. Indiana also requested removing the process weight rate limits and using pounds of PM10 per hour (lb/hr) as the short-term emission limit. The maximum permissible PM10 emissions will not increase after removing the process weight rate limits because of the net decrease in short-term emission limits.
