Division of Environmental Protection,

and California Department of Health

Services. The purpose of this

stakeholder forum is to disseminate

information on the key scientific issues,

to identify additional issues, and to hear

stakeholder concerns. The IPSC is

seeking input from State and Tribal

drinking water programs, the regulated

community (public water systems),

public health organizations, academia,

environmental and public interest

groups, engineering firms, and the

public on a number of issues related to

perchlorate contamination in the

environment. The IPSC encourages the

full participation of stakeholders at the

forum.

DATES: The forum will be held on

Tuesday, May 19, 1998 from 8:30 a.m.

to 5:30 p.m. PDT, Wednesday, May 20,

1998 from 8:30 a.m. to 5:00 p.m. PDT,

with an additional public outreach

evening session from 7:00 p.m. to 9:00

p.m. PDT, and Thursday, May 21, 1998

from 8:30 a.m. to 12:00 p.m. PDT.

LOCATION: The Henderson Convention

Center in Henderson, Nevada. To

register, please contact the EPA Safe

Drinking Water Hotline at 1–800–426–

4791 or 703–285–1093 between 9:00

a.m. and 5:30 p.m. EDT. Those

registered by May 13, 1998, will receive

a draft agenda, logistics information,

and discussion papers prior to the

forum. Members of the public who

cannot attend in person may participate

via conference call and should also

register with the EPA Safe Drinking

Water Hotline by May 13, 1998. When

registering, please indicate it is for the

‘‘Perchlorate Forum’’ and provide your

name, organization, title, mailing

address, telephone number, facsimile

number, and e-mail address. Conference

lines will be allocated on the basis of

first-reserved, first served.

FOR FURTHER INFORMATION CONTACT: For

additional information on forum

logistics, please contact the EPA Safe

Drinking Water Hotline at 1–800–426–

4791.

SUPPLEMENTARY INFORMATION:

A. Background

Perchlorate is used as an oxidizer

component in solid propellant (fuel) for

rockets, missiles, and fireworks. It is

very soluble in water, mobile in aqueous

systems and can persist for many

decades under typical ground water and

surface water conditions. Recent (April

1997) advances in the analytical

detection capability for low

concentrations of perchlorate, from 400

to 4 parts per billion (ppb), have led to

the discovery of the chemical at various

manufacturing sites and some drinking

water supply wells of communities in

California, Nevada, and Utah.

Perchlorate has been found in ground

water at six Superfund hazardous waste

sites in California, at six other California

non-Superfund waste sites, two sites in

the Henderson, Nevada area, one site in

Utah, and in the discharge to a creek in

Texas. Water suppliers in both northern

and southern California, and the Las

Vegas Water Authority have found

perchlorate in their water supplies

generally at levels less than 18 ppb but

ranging as high as 280 ppb, with several

in the 100–200 ppb range. Perchlorate

has also been detected at low levels (5

to 9 ppb) in the Colorado River.

Concerns have been raised about

perchlorate because of the lack of

adequate scientific information about

the contaminant, including: where the

contamination occurs, what reliable

methods exist to detect it in various

media, what the potential health effects

are, and what treatment technologies

exist. Historically, potassium

perchlorate was used therapeutically to

treat hyperthyroidism in Graves’ Disease

patients because it inhibits iodine

uptake and thereby reduces thyroid

hormone production. Thyroid hormone

deficiencies can affect normal

metabolism, growth, and development.

Currently, perchlorate does not have a

National Primary Drinking Water

Regulation (NPDWR) or Health

Advisory (HA) established. Under the

Safe Drinking Water Act (SDWA), as

amended in 1996, EPA is required to

develop a list of contaminants, known

as the Contaminant Candidate List

(CCL), that are known or anticipated to

occur in public water systems and may

require regulation under SDWA [section

1412(b)(1)]. As a result of public

comment on a draft of the CCL

published on October 6, 1998 (62 FR

52193), perchlorate was added to the

final CCL that was published on March

2, 1998 (63 FR 10274). At this time,

additional research on health effects,

effective treatment technologies,

analytical methods, and occurrence is

necessary before a determination can be

made of whether to regulate perchlorate

with an NPDWR or to develop guidance.

B. Request for Public Involvement

The IPSC is encouraging development

of a sound research and management

strategy by the involved government

agencies through facilitating

identification of the issues concerning

perchlorate contamination and by

coordinating information exchange to

ensure the incorporation of the best

available science and stakeholder input

on technical and policy issues.

The stakeholder forum will cover a

broad range of topics including: (1) Key

exposure characterization issues

(occurrence and sites of known

contamination, transport and

transformation, analytical methods); (2)

perchlorate health risk assessment

(health effects and toxicology studies,

the peer review process); (3) key

technical assessments (treatment

technologies, waste stream handling);

(4) ecological impacts; (5) regulatory

and policy issues and; (6) future

stakeholder involvement. Background

materials on perchlorate issues will be

sent in advance of the forum to those

who register with the EPA Safe Drinking

Water Hotline by May 13, 1998.

The IPSC has announced this forum

to hear the views of stakeholders on

actions that the agencies represented by

the IPSC are taking or are planning to

take to address perchlorate

contamination. The public is invited to

participate fully during the May 19–21,

1998 forum and during future

opportunities for stakeholder

participation.

SUPPLEMENTARY INFORMATION:

Electronic Availability: Electronic

copies of this document and various

support documents are available from

the EPA home page at the Federal

Register-Environmental Documents

entry for this document under ‘‘Laws

and Regulations’’ (http://www.epa.gov/

fedrgstr/).

The Agency has issued Reregistration

Eligibility Decision (RED) documents for

the pesticidal active ingredients listed

above. Under the Federal Insecticide,

Fungicide, and Rodenticide Act, as

amended in 1988, EPA is conducting an

accelerated reregistration program to

reevaluate existing pesticides to make

sure they meet current scientific and

regulatory standards. The data base to

support the reregistration of each of the

chemicals listed above is substantially

complete.

Please note that these REDs were

finalized and signed after August 3,

1996. On that date, the Food Quality

Protection Act of 1996 (‘‘FQPA’’)

became effective, amending portions of

both the pesticide law (FIFRA) and the

food and drug law (FFDCA). All of these

REDs address the requirements of FQPA

as appropriate.

All registrants of products containing

one or more of the above listed active

ingredients have been sent the

appropriate RED documents and must

respond to labeling requirements and

product specific data requirements (if

applicable) within 8 months of receipt.

Products containing other active

ingredients will not be reregistered until

those other active ingredients are

determined to be eligible for

reregistration.

The reregistration program is being

conducted under Congressionally

mandated time frames, and EPA

recognizes both the need to make timely

reregistration decisions and to involve

the public. Therefore, EPA is issuing

these REDs as final documents with a 60

day comment period. Although the 60

day public comment period does not

affect the registrant’s response due date,

it is intended to provide an opportunity

for public input and a mechanism for

initiating any necessary amendments to

the RED. All comments will be carefully

considered by the Agency. If any

comment significantly affects a RED,

EPA will amend the RED by publishing

the amendment in the Federal Register.

Electronic copies of the REDs and

RED fact sheets can be downloaded

from the Pesticide Special Review and

Reregistration Information System at

(703) 308–7224, and also can be reached

on the Internet via EPA’s website at:
