igr EPA Project Summary
Proceedings of International
Workshop on Research in
Pesticide Treatment/Disposal/
Waste Minimization
T. David Ferguson
An international workshop on treat-
ment, disposal, and waste minimization
of pesticides and pesticide wastes was
held in Cincinnati, OH, on February 26-
27,1991. The purpose of this workshop
was to work with government, pesticide
user groups, pesticide producers, farm
organizations, and academia to define
and offer practical solutions to pesti-
cide users' treatment and disposal prob-
lems. The technical program included
presentations by government research-
ers and regulators, academia, industry
experts, and individuals Involved in pes-
ticide disposal and treatment.
The workshop was sponsored by the
following organizations:
U.S. Environmental Protection
Agency
Office of Research and Development
Risk Reduction Engineering Labora-
tory
Cincinnati, Ohio 45268
and
Tennessee Valley Authority
National Fertilizer and Environmen-
tal Research Center

This Project Summary was devel-
oped by EPA's Risk Reduction Engi-
neering Laboratory, Cincinnati, OH, to
announce key findings of the research
project that is fully documented In a
separate proceedings of the same title
(see Project Report ordering Informa-
tion at back).
Aside from the technical presentations,
the workshop allowed for some discussion
among the participants. Several issues/
concerns were discussed by the attend-
ees. The two issues which caused the
greatest concern were site remediation and
regulatory framework.
Discussions on site remediation were
directed toward dealer sites. The focuses
on the cleanup were both soils and ground-
water contamination. The largest problems
identified with dealer site cleanup were
costs and issues of how clean is clean
enough. It was noted that many dealers
could go bankrupt if costs were high. Also,
little remediation is being conducted be-
cause dealers feel that regulators cannot
give them cleanup levels that will hold true
in the future.
Regulatory framework is also of great
concern. Discussion ensued regarding how
to solve this problem. Suggestions included
the following:
1) Prove technology first, then worry
about the regulatory framework.
2) Regulatory framework needs to be
looked at while technology is being
developed—it can and does drive
costs.
3) Policy people are not listening to re-
search people.
4) Get the key players involved. Target
state regulators since they are clos-
est to the problem. Get the concerns
and scientific information to the perti-
nent regulatory people.
Another topic of discussion was waste
minimization and education. It was agreed
that many pollution prevention ideas would
significantly decrease the number of future
problems involving pesticides. These waste
minimization techniques were generally
low-cost practical solutions to managing

pesticides and pesticide wastes. It is im-
portant that these ideas become common
practices through education of appropriate
users and dealers of pesticides.
