Federal Insecticide, Fungicide
and Rodenticide Act (FIFRA)
EPA Pesticide Classification
Explained
Federal Insecticide,
Fungicide and Rodenticide Act (FIFRA)
FIFRA was enacted in 1947 and has been amended
several times since then. The most important amendment to FIFRA
is the 1972 Federal Environmental Pesticide Control Act (FEPCA).
It deals with protection of both public health and the environment.
FIFRA governs the licensing of pesticides. It
gives the U. S. Environmental Protection Agency (EPA) the power
to approve pesticides before they can be sold in the United States.
Each use for a pesticide must receive EPA approval. The pesticide
also must receive an EPA registration number. These rules enable
EPA to make sure the pesticide will not cause "unreasonable
human health or environmental effects."
All schools that use pesticides are subject to
provisions under FIFRA. The most important of which is that the
label is a legal document; any time a pesticide is misapplied it
is a violation of FIFRA.

EPA Pesticide Classification
Explained
Pesticides are classified in several ways, each
having its own value for a given purpose. Some pesticides are classified
by the EPA as restricted-use pesticides (RUP's) which means that
the product has the potential to harm humans or the environment,
if it is not used correctly. Only a certified applicator may mix,
load, apply, or direct the use of restricted-use pesticides. There
are very few situations where RUP's should be used in or around
schools.
Pesticides are also classified based on their
toxicity level. Acute (fast acting, single dose, immediate response)
toxicity values of a pesticide determine the toxicity category of
the pesticide and the signal word(s) required on the pesticide label.
The toxicity category is assigned on the basis of the highest measured
toxicity, oral, dermal, or inhalations; effects on the eyes and
external injury to the skin are also considered. The toxicity category
and, therefore, the signal word(s) are based on the total formulation.
Thus, products containing the same active ingredient but in different
formulations may bear different signal words.
Toxicity in pesticides are given in terms
of LD50 (Lethal Dose Fifty), expressed as milligrams of toxicant
per kilogram of body weight, the dose that kills 50 percent of the
test animals. This rating only tells us how much chemical it takes
to kill half the test animals.

Right-to-Know
Some parents want to know about the dangers of pests and about
the pest control products that are used in their children's schools
to control these pests. This information should be made available
to parents, as long as the information disclosed is factual and
disclosed in a manner that does not create an undue burden on schools.
Parents should be informed about the pest problems children could
face in school buildings and on school grounds, including cockroaches,
rodents, mosquitoes, ticks, fire ants, stinging insects, poison
ivy, bacteria and viruses. They should also be advised that all
pest control products used in schools are thoroughly tested and
registered for that use with the U.S. Environmental Protection Agency
and the appropriate state regulatory agency. Schools should also
provide to interested parents information about pest management
products being used and additional information about the school's
IPM program.
In implementing right-to-know provisions as part of a school IPM
plan, it is important that the limitations of school resources be
taken into account. For example, it is unreasonable to notify all
parents in a school district before all pesticide applications,
including products used in rest rooms, cafeterias and other school
facilities. Notifying parents at the beginning of a school year
about the school district's integrated pest management plan and
allowing parents who wish to be notified about specific pesticide
applications is a much better use of school resources.
The issue of right-to-know and public participation is incorporated
into several federal and state laws. The Emergency-Planning and
Community Right-to-know Act (EPCRA), for example, requires companies
to report to EPA releases of any pollutants into the environment.
It also requires companies to prepare and submit plans to the agency
about how the company would clean up any chemical accident and notify
the surrounding community about the incident.
This information is available to the public; although EPA is re-evaluating
how much and what types of information should be publicly disclosed
in light of the September 11 terrorist attacks. After the attacks,
EPA removed from the Internet company chemical emergency risk management
plan data, out of concern that this information could be used by
terrorist organizations to plan additional attacks against the United
States.
At a recent Environmental Law Institute conference on right-to-know,
Elaine Stanley, director of EPA's Office of Information Analysis
and Access, said the agency is "trying to figure out whether
there are better ways to manage the public dissemination of information,"
such as making available less-detailed information, or making it
available to a smaller, more limited group of people.
