Cleanup Standards Scientific Advisory Board, Risk Assessment Subcommittee Meeting on Resorcinol

[34 Pa.B. 3323]

   The Cleanup Standards Scientific Advisory Board (Board) Risk Assessment Subcommittee (Subcommittee) will meet on July 12, 2004, from 9:30 a.m. to 12 p.m. to discuss issues related to the development and review of the reference dose (RfD) values of resorcinol (CAS # 108-46-3) and the development of the medium-specific concentrations (MSCs) for resorcinol. The meeting will be held in the large conference room on the 14th Floor, Rachael Carson State Office Building, 400 Market Street, Harrisburg, PA. A speaker phone will be provided as the Board members will be participating by teleconference. For further information, contact Dave Hess, (717) 783-9480, The agenda and meeting materials for the July 12, 2004, meeting will be available through the Public Participation Center on the Department of Environmental Protection's (Department) website: (DEP Keyword: Participate).

   Persons with a disability who require accommodations to attend the July 12, 2004, meeting should contact the Department at (717) 783-9480 or through the Pennsylvania AT&T Relay Services at (800) 654-5984 (TDD) to discuss how the Department may accommodate their needs.

   Resorcinol is one of the regulated substances listed at 25 Pa. Code Chapter 250, Appendix A, Table 6 (relating to threshold of regulation compounds) as a threshold-of-regulation compound. Compounds are listed in this table because reference dose and cancer slope factor were not available at the time of the last regulation amendment in 2001, so that the derivation of compound-specific MSCs was not possible. For resorcinol, the situation has changed since then. Additional toxicological data for resorcinol are now available.

   The main purpose of this Subcommittee meeting is to review the latest information regarding the derivation of RfD values for resorcinol. Additional discussions will focus on issues specifically related to resorcinol under the Statewide health standard, including how the secondary maximum contaminant levels of foaming agents, color and odor may impact the implementation of MSCs for resorcinol.
