Proposed National Action Plan for Hexachlorobenzene; Notice of 
Availability and Solication of Public Comment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Availability.

-----------------------------------------------------------------------

SUMMARY: EPA has developed a draft National Action Plan to promote 
further voluntary reductions of releases and exposure to 
Hexachlorobenzene (HCB). This Notice announces the availability of the 
draft HCB National Action Plan for public review and comment. 
Hexachlorobenzene is currently formed as an inadvertent by-product at 
trace levels in the production of chlorinated solvents, pesticides, and 
in other chlorinated processes. This chemical is a persistent, 
bioaccumulative and toxic halogenated compound that persists in the 
environment and bioaccumulates in animal tissue. It is considered a 
probable human carcinogen and is toxic by all routes of exposure. The 
general population appears to be exposed to very low concentrations of 
HCB, primarily through ingestion of meat, dairy products, poultry and 
fish. The strategic approach of the Agency,

[[Page 77027]]

therefore, will involve voluntary initiatives to reduce releases and 
minimize media transfers, collect information to verify sources and 
sinks, and increase involvement with and assistance to international 
groups and other countries to reduce atmospheric deposition in the 
United States. This plan was developed pursuant to the Agency's 
Multimedia Strategy for Priority PBT Pollutants.

DATES: Comments, identified by docket control number OPPTS-00300, must 
be received on or before January 8, 2001.

ADDRESSES: Comments may be submitted by mail, electronically, or in 
person. Please follow the detailed instructions for each method as 
provided in Unit I. of the SUPPLEMENTARY INFORMATION. To ensure proper 
receipt by EPA, it is imperative that you identify docket control 
number OPPTS-00300 in the subject line on the first page of your 
response.

Action Plan may also be of interest to persons involved in the use of 
hexachloroethane in secondary aluminum operations which could release 
HCB. Since other entities may also be interested, the Agency has not 
attempted to describe all the specific entities that may be affected by 
this action. If you have any questions regarding the applicability of 
this action to a particular entity, consult the technical person listed

 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) 
Pollutants (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 Hexachlorobenzene (HCB), one of the 
12 Level 1 priority PBT pollutants identified for the initial focus of 
action in the PBT Strategy.
    Hexachlorobenzene (CAS number 118-74-1) is a white, crystalline 
solid. It has been synthesized and used from the 1940s to the late 
1970s as a fungicide on grain seeds such as wheat. HCB was also used in 
the past as a solvent and as an intermediate and/or additive in various 
manufacturing processes, including the production of PVC, pyrotechnics 
and ammunition, dyes, and pentachlorophenol. Although HCB is no longer 
used directly as a pesticide, it is currently formed as an inadvertent 
by-product at trace levels in the production of chemical solvents, 
chlorine-containing compounds, and several currently used pesticides.
    HCB is a highly persistent environmental toxin that degrades slowly 
in air and remains in the atmosphere through long range transport. It 
bioaccumulates in the fatty tissues and its presence in fish, plants, 
and wild game species can be a source of ingestion exposure for humans. 
HCB is considered a probable human carcinogen and is toxic by all 
routes of exposure. Short-term high exposures can lead to kidney and 
liver damage, central nervous system excitation and seizures, 
circulatory collapse, and respiratory depression. Based on studies 
conducted on animals, long-term low exposures may damage a developing 
fetus, cause cancer, lead to kidney and liver damage, and cause fatigue 
and skin irritation.
    The general population appears to be exposed to very low 
concentrations of HCB. Ingestion of HCB-contaminated fish and other 
wildlife is potentially the most significant source of exposure. 
Additional, although significantly less, exposure may occur through 
inhalation or dermal contact. However, certain subpopulations may be 
exposed to higher levels of HCB than the general population. These 
include: workers occupationally exposed to HCB; individuals living near 
facilities where HCB is produced as a by-product; individuals living 
near current or former hazardous waste sites where HCB is present; 
recreational and subsistence fishermen who consume higher amounts of 
locally caught fish and bivalves (mussels, oysters, clams) from 
contaminated waters, and native populations (including Native American 
populations such as the Inuits of Alaska) who consume caribou and other 
game species. Finally, nursing infants in these areas may also be 
particularly susceptible to effects due to the singular nature of their 
diet.
    The goal of the Action Plan is to identify and further reduce risks 
to human health and the environment from existing and future exposure 
to HCB. However, there are information gaps related to the magnitude of 
known and suspected sources of HCB, the extent of pollution resulting 
from long-range transport, and the content of HCB in sinks such as 
sediments and sewage sludge that may contribute to environmental 
cycling within Unites States boundaries. Therefore, the strategic 
approach of the Agency will involve voluntary initiatives to reduce 
releases and minimize media transfers, collect information to verify 
sources and sinks, and increase involvement with and assistance to 
international groups and other countries to reduce atmospheric 
deposition in the United States.
    EPA considers stakeholder involvement essential to reaching the 
goals of the PBT Strategy. Therefore, the Agency is seeking stakeholder 
input and invites comment on this draft National Action Plan on the 
following three areas related to HCB.
    1. The identification and implementation of voluntary initiatives 
and outreach opportunities to reduce releases of and exposure to HCB, 
while minimizing controlled and uncontrolled (e.g., volatilization from 
water to air, deposition onto soil or plants) multi-media transfers.
    2. Continued information collection and integration of data across 
media regarding sources, sinks, releases, environmental trends, and 
human food and tissue levels for HCB. Data collection will occur 
through Binational Toxics Strategy (BNS) efforts, Maximum Achievable 
Control Technology (MACT) standard development, various EPA permitting 
and reporting processes, and industry involvement.
    3. Collaborate (or partner) with international organizations and 
foreign governments to assess the significance of long-range transport 
from other countries and to foster the proliferation of pollution 
prevention or control technology measures that will reduce inputs of 
HCB to the environment.
