AGENCY:

Environmental Protection Agency.

ACTION:

Proposed rule; notice of a public meeting.

SUMMARY:

The Environmental Protection Agency (EPA) is holding a public meeting to discuss recent research related to the proposed Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR).

DATES:

The public meeting will be held from 9 a.m. to 4 p.m., Eastern time, on Tuesday, January 18, 2005.

ADDRESSES:

The meeting will be held on the first floor of the East Building of EPA Headquarters in Room 1153. The address is EPA East, 1201 Constitution Ave., NW., Washington, DC.

FOR FURTHER INFORMATION CONTACT:

For general information about this meeting, contact Sarah Bahrman by phone at (202) 564-2335, by e-mail at bahrman.sarah@epa.gov, or by mail at: U.S. Environmental Protection Agency, Mail Code 4607M, 1200 Pennsylvania Ave., NW., Washington, DC 20460. For technical inquiries regarding the Stage 2 Disinfectants and Disinfection Byproducts Rule, contact Tom Grubbs at (202) 564-5262, or by e-mail: grubbs.thomas@epa.gov.

SUPPLEMENTARY INFORMATION:

The purpose of the public meeting is to discuss recent research related to the Stage 2 DBPR. EPA proposed the Stage 2 DBPR on August 18, 2003 (68 FR 49547) and is currently working on the final rule. The proposed Stage 2 DBPR was developed based on recommendations from a Federal Advisory Committee, which consisted of a broad range of stakeholders. EPA will build on this collaborative process by way of this public meeting.

Research areas and examples of recent studies that the Agency plans to discuss at the meeting are listed at the end of this notice. This is not a comprehensive list of all recent disinfection byproduct research. A longer list of recent research can be found on the Agency's Web site at http://www.epa.gov/safewater/stage2/index.html. All copyrighted studies are available only in hard copy form and are accessible at the Water Docket in the EPA Docket Center, EPA/DC, EPA West, Room B102, 1301 Constitution Ave., NW., Washington, DC. The Public Reading Room is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal holidays. The telephone number for the Public Reading Room is (202) 566-1744, and the telephone number for the Water Docket is (202) 566-2426.

Attendees will have an opportunity to make oral remarks at specific points during the meeting. EPA also welcomes written remarks received by February 17, 2005, which can be sent to Sarah Bahrman by e-mail or by mail at the address listed in the previous section.

The main entrance to the building on Constitution Avenue is a short distance from the Federal Triangle Metro Station, which is located on 12th Street between Constitution and Pennsylvania Avenues and is served by the Blue and Orange Lines. Please note that attendees will be required to pass through security checks at the front desk and obtain a visitor's badge. All attendees will need to present a photo I.D. The building is accessible to persons using wheelchairs or scooters. Any person needing special accommodations at this meeting, including wheelchair access, should contact Sarah Bahrman (contact information provided in the previous section) at least five business days before the meeting so that the Agency can make appropriate arrangements.
