ENVIRONMENTAL PROTECTION AGENCY
[FRL-5941-1]
Technical Workshop on Drake Site Incinerator Risk Issues
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of meeting.
-----------------------------------------------------------------------
SUMMARY: EPA is announcing a workshop convened by Eastern Research
Group, Inc., an EPA contractor, for scientific peer review of the EPA
draft risk assessment for the Drake Chemical Superfund Site Incinerator
full-scale operation in Lock Haven, Pennsylvania. The workshop will be
held in Williamsport, Pennsylvania, and will be open to members of the
public as observers. The peer review, to be conducted by scientists
from outside EPA, is being organized to assist in completing the risk
assessment.
DATES: The workshop will begin on Thursday, January 15, 1998 at 12 Noon
and end on Friday, January 16, 1998 at 12:30 p.m. Members of the public
may attend as observers.
ADDRESSES: The meeting will be held at the Genetti Hotel & Conference
Center, 200 West 4th Street, Williamsport, Pennsylvania 17701. Since
seating capacity is limited, please contact Eastern Research Group,
Inc., Tel.: (781) 674-7374, by January 9, 1998 to attend the workshop
as an observer.
FOR FURTHER INFORMATION CONTACT: For technical inquires, contact Mr.
Gregg Crystall, U.S. EPA Region III, 841 Chestnut Street, Philadelphia,
PA 19107. Tel.: (215) 566-3207. Copies of the draft risk assessment
will be available for inspection in the EPA Region III Library,
Philadelphia, PA, and the EPA Headquarters Information Resources
Center, Washington DC. In addition, the draft risk assessment will be
available for inspection in: the Ross Public Library, West Main Street,
Lock Haven, PA, 17745; the Stevenson Library, Lock Haven University,
Lock Haven PA, 17745; and the Lock Haven City Hall, 20 East Church
Street, Lock Haven, PA, 17745. Inquiries concerning additional
opportunities for document review should be directed to Mr. Crystall.
SUPPLEMENTARY INFORMATION: While operational, the Drake Chemical
Company in Lock Haven, Pennsylvania was sited numerous times by State
and Federal agencies for violating environmental and health and safety
regulations. In 1982 as a response to the Company's noncompliance with
environmental regulations, EPA Region III undertook emergency removal
actions. These actions included removal and disposal of surface drums,
surface sludges, and liquids contained in process and storage tanks,
and placement of fences around the property. Additional remediation
actions have been conducted in several phases since then. Phase I
remedial activities included the remediation of a leachate stream
draining into Bald Eagle Creek. Phase II included drainage and removal
of materials from two lined Lagoons, and demolition and removal of the
on-site buildings. Subsequent studies conducted at the site indicated
that the remaining contamination in soils presented a serious threat to
the environment and human health. The 1988 Record of Decision concluded
that the remaining site wastes, approximately 200,000 cubic yards of
contaminated site soils, sediments, and sludges from the on-site
lagoons, should be excavated and treated on-site in a high temperature
incinerator. The excavated soils would be stockpiled temporarily,
remediated in an on-site rotary kiln incinerator, then returned to the
site. After all the contaminated soil had been remediated, the
incinerator would be dismantled and removed from the site.
Prior to full-scale operation, a trial burn process was conducted
to ensure incinerator equipment functioned according to operational and
safety specifications. Prior to conducting this evaluation, EPA Region
III prepared a trial burn process risk assessment (June, 1996). The
trial burn process risk assessment was developed using approximated
data drawn from site soil samples, anticipated soil feed rates,
incinerator design parameters, and emissions data from other
incinerators. Results of the trial burn risk assessment were presented
during a public meeting held in September 1996. The trial burn process
was conducted in January and February 1997.
Most recently, EPA Region III developed a full-scale operation risk
assessment by utilizing actual data collected during the trial burn
process. The resulting Draft Drake Chemical Site Incinerator Full-Scale
Operation Risk Assessment (November 1997) is the subject of the current
peer review.
For the current review, EPA is inviting a panel of 14 independent
scientists from the fields of toxicology, environmental fate and
transport, combustion engineering, atmospheric modeling, exposure
assessment, and ecological assessment. These scientists will focus on
the scientific data, methods, and analyses, along with the assumptions
and uncertainties that are associated with full-scale operation risk
estimates. Following the workshop, EPA will consider the scientist's
individual recommendations in completing the risk assessment. The risk
assessment documents undergoing review relate only to scientific
issues. Although the completed risk assessment will be one of the
factors considered in making future decisions for the Drake Chemical
site, these decisions and other risk management issues will not be a
part of the peer review process.
