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,

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.
