# AGENCY:

 Environmental Protection Agency (EPA).

# ACTION:

Notice.

# SUMMARY:

 EPA has developed a draft National Action Plan to address the remaining risks to the Level 1 priority Persistent, Bioaccumulative, and Toxic (PBT) pesticide pollutants. This proposed National Action Plan covers the chemical compounds: Aldrin, Dieldrin, Chlordane, DDT, Mirex and Toxaphene. These six pesticides are highly chlorinated, persistent organic pesticides that were once widely used in large quantities in the United States.  Because of evidence supporting the adverse environmental and human health effects of these substance, including their probable carcinogenicity, the pesticide use of all of the Level 1 pesticides were canceled in the U.S. in the 1970's and 80's. Current data substantiate that these Level 1 pesticides are still ubiquitous in the environment, and at concentrations that may be of concern for both humans and wildlife. This plan, developed pursuant to the Agency 's Multimedia Strategy for Priority PBT Pollutants, addresses the remaining risks.  This Notice announces the availability of the proposed Pesticide national Action for public review and comment.

## II. What Action Is the Agency Taking?

On November 16, 1998, EPA released its draft Agency-wide Multimedia Strategy for Priority Persistent, Bioaccumulative, and Toxic (PBT) Polutants (PBT Strategy). The goal of the PBT Strategy is to identify and reduce risks to human health and the environment from current and future exposures to priority PBT pollutants. This document serves as the Draft National Action Plan for the Level 1 pesticides; six of the 12 Level 1 priority PBT pollutants identified for the initial focus of action in the PBT Strategy.

Aldrin, dieldrin, chlordane, DDT, mirex, and toxaphene were once widely used in large quantities in the United States for applications, including: insect control on agricultural crops and cotton, treatment of livestock, control of ants, termite control in houses, and control of insect carriers of human diseases such as malaria. Because of evidence supporting the adverse environmental and human health effects of these substances, including their probable carcinogenicity, the pesticide uses of all of the Level 1 pesticides were canceled in the U.S. in the 1970's and 80's. In general, the remaining sources of Level 1 pesticides in the United States include: unused stocks of these canceled pesticides; contaminated reservoirs such as sediments, soil, and localized contaminated industrial and dealership sites; atmospheric transport and deposition (from both regional and international sources); and DDT present as an impurity (<0.1%) in Dicofol, a pesticide currently used in the U.S. and Canada.

Human exposure occurs mainly through the food chain and for the most exposed populations, is probably due to the consumption of contaminated fish. Potential risk and health consequences due to the Level 1 pesticides are of particular concern for certain human populations who have increased exposure (e.g., subsistence fishers) and/or increased susceptibility (e.g., the developing embryo/fetus, nursing infants, and children).

                    Data gathered in current multimedia monitoring efforts provided substantial evidence that the Level 1 pesticides are still ubiquitous in the environment, and at concentrations that may be of concern for both humans and wildlife. There are also significant quantities of unused, obsolete pesticide stocks stored throughout the U.S. and overseas which have the potential to cause serious                           ( print page 65316)                        environmental contamination and human health risks if accidentally released or not disposed of properly. This plan attempts to address these remaining risks by: (1) Supporting programs to collect and properly dispose of unwanted pesticides; (2) remediating nonpoint and reservoir sources like sediments, contaminated industrial sites, agricultural chemical dealer/storage sites, and past use sites on a priority basis; (3) reducing human exposure through public education, fish consumption advisories, and other outreach activities; (4) working with foreign governments to reduce or phase -out production and use of these substances, thereby reducing the risks from long -range transport; and (5) continued monitoring for environmental levels in fish, wildlife, and humans.                

EPA considers stakeholder involvement essential to reaching the goals of the PBT Strategy. EPA is seeking stakeholder input and invites comment on this draft National Action Plan on the following topics and issues related to the PBT Level 1 pesticides:

1. Quantities of domestic unused stocks of pesticide products.

2. Historical trends or current soil residues (urban and agricultural).

3. Information on sites with significant Level 1 pesticide contamination.

4. Current indoor levels of pesticides used in residents.

5. Alternative disposal and soil/sediment remediation methods, and performance information.

6. Other sensitive or highly exposed human subpopulations.

7. Meaningful and feasible ways to address the problem of canceled pesticides in the environment.

8. Meaningful PBT goals, performance measures, and time frames for such accomplishments.
