Technical Workshop Report on WTI Incinerator Risk Issues

AGENCY: Environmental Protection Agency.

ACTION: Notice of availability of workshop report.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing the availability of the ``Report on the U.S. 
EPA Technical Workshop on WTI Incinerator Risk Assessment Issues.'' 
This is a workshop report for the scientific peer review of a draft 
risk assessment, prepared by EPA Region V, for the Waste Technologies 
Industries (WTI) hazardous waste incinerator in East Liverpool, Ohio. 
The report contains the peer review panel's recommendations and 
premeeting comments addressing various aspects of the draft risk 
assessment. The peer review was conducted by scientists from outside 
EPA. The workshop was held in Washington, DC, at the Holiday Inn 
Georgetown on January 11, 1996.

ADDRESSES: Interested parties can obtain a single copy of the workshop 
report by contacting: The Office of Research and Development (ORD) 
Publications Office, Technology Transfer Division, National Risk 
Management Research Laboratory, U.S. Environmental Protection Agency, 
26 W. Martin Luther King Drive, Cincinnati, OH 45268; telephone (513) 
569-7562; facsimile (513) 569-7566. Please provide your name and 
mailing address, and request the document by the title and EPA document 
number (EPA/630/R-96/001). There will be a limited number of paper 
copies available from the above source. Requests will be filled on a 
first-come-first-served basis. After the supply is exhausted, copies of 
the workshop report can be purchased from the National Technical 
Information Service (NTIS) by calling (703) 487-4650 or sending a 
facsimile to (703) 321-8547. The NTIS order number for this document is 
PB96-177763.

FOR FURTHER INFORMATION CONTACT:
William Wood, Risk Assessment Forum (8103), U.S. Environmental 
Protection Agency, 401 M Street, S.W., Washington, DC, 20460, Telephone 
(202) 260-6743.

SUPPLEMENTARY INFORMATION: Previously, several preliminary risk 
assessments were conducted by EPA's Region V, working with the Office 
of Solid Waste and Emergency Response and the Office of Research and 
Development, concerning the WTI incinerator. To prepare for a final, 
detailed risk assessment the EPA decided, in July 1993, that the Agency 
would arrange independent scientific peer reviews of both the project 
plan and the draft risk assessment. The first peer review was held in 
December 1993 (59 FR 60628-60629, 17 Nov. 1993) and concerned the EPA 
Region V draft project plan for the risk assessment. For this first 
workshop, EPA convened a peer review panel of 13 independent scientists 
from the fields of toxicology, environmental fate and transport, 
combustion engineering, atmospheric modeling, and exposure assessment. 
The comments and recommendations provided during this workshop are 
published in ``Report on the Technical Workshop on WTI Incinerator Risk 
Issues'' (EPA/630/R-94/001). This document is available from the ORD 
Publications Office (Phone 513-569-7562). Major recommendations from 
this workshop included: (1) using additional incinerator performance 
test data; (2) refining computer models used to simulate airborne 
dispersions; (3) conducting a screening level ecological risk 
assessment; and (4) performing an evaluation of accident scenarios.
    For the EPA Region V draft risk assessment review, a second 
workshop was held on January 11, 1996 (60 FR 61552-61553, 30 Nov. 
1995). This meeting was originally planned for two days but was 
compressed due to severe weather conditions. For this workshop, EPA 
convened many of the original panelists, and six additional experts in 
the areas of ecological risk assessment and accident analysis. These 
scientists focused on the scientific data, methods, and analyses, along 
with the assumptions and uncertainties that are associated with the 
risk estimates at the site. The comments and recommendations provided 
during this workshop are presented in the report entitled ``Report on 
the U.S. EPA Technical Workshop on WTI Incinerator Risk Assessment 
Issues'' (EPA/630/R-96/001). EPA Region V will consider the workshop 
recommendations presented in this report in completing the risk 
assessment.
