ii. Developmental toxicity studies. In

the prenatal developmental toxicity

studies in rats and rabbits, there was no

evidence of developmental toxicity at

the HDT (35.0 mg/kg/day in rats and

700 mg/kg/day in rabbits). Decreased

body weight gain was observed at the

maternal LOEL in each study; the

maternal NOEL was established at 12.5

mg/kg/day in rats and 100 mg/kg/day in

rabbits.

iii. Reproductive toxicity study. In the

2-generation reproduction study in rats,

offspring toxicity (body weight) and

parental toxicity (body weight, organ

weight, and clinical signs) was observed

at 27.0 mg/kg/day and greater. The

parental systemic NOEL was 7.0 mg/kg/

day and the parental systemic LOEL was

27.0 mg/kg/day. There were no

developmental (pup) or reproductive

effects up to 45.0 mg/kg/day, HDT.

iv. Pre- and post-natal sensitivity—a.

Pre-natal. There was no evidence of

developmental toxicity in the studies at

the HDT in the rat (35.0 mg/kg/day) or

in the rabbit (700 mg/kg/day). Therefore,

there is no evidence of a special dietary

risk (either acute or chronic) for infants

and children which would require an

additional safety factor.

b. Post-natal. Based on the absence of

pup toxicity up to dose levels which

produced toxicity in the parental

animals, there is no evidence of special

post-natal sensitivity to infants and

children in the rat reproduction study.

c. Conclusion. Based on the above,

FMC concludes that reliable data

support use of the standard 100-fold

uncertainty factor, and that an

additional uncertainty factor is not

needed to protect the safety of infants

and children. As stated above, aggregate

exposure assessments utilized

significantly less than 1 % of the RfD for

either the entire U. S. population or any

of the 26 population subgroups

including infants and children.

Therefore, it may be concluded that

there is reasonable certainty that no

harm will result to infants and children

from aggregate exposure to

cypermethrin residues.

3. Subchronic toxicity— Short- and

intermediate-term toxicity. The NOEL of

3.8 mg/kg/day based on the NOEL 7.5

mg/kg/day from the cypermethrin

toxicity/oncogenicity study in rats and a

correction factor of two to account for

the biologically active isomer would

also be used for short- and intermediateterm MOE calculations (as well as acute,

discussed in (E.1.) above). The LOEL of

this study of 50.0 mg/kg/day was based

on neurological signs observed in the

first week of the study.

F. International Tolerances

There are no Codex, Canadian, or

Mexican residue limits for residues of

zeta-cypermethrin in or on Brassica,

head and stem vegetables; Brassica,

leafy vegetables; and leafy vegetables

(except Brassica vegetables) group.

Proposed CERCLA Prospective

Purchaser Agreement and Proposed

CERCLA Section 122(h)(1)

Administrative Cost Recovery

Settlement Agreement for the IngramRichardson Site

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposal of CERCLA

Prospective Purchaser Agreement and

Proposal of CERCLA section 122(h)(1)

Administrative Cost Recovery

Settlement Agreement for the IngramRichardson site.

SUMMARY: In accordance with the

Comprehensive Environmental

Response, Compensation, and Liability

Act of 1980 (CERCLA), 42 U.S.C. 9601

et seq., as amended by the Superfund

Amendments and Reauthorization Act

of 1986 (SARA), Pub. L. 99–499,

notification is hereby given that a

proposed Agreement and Covenant Not

to Sue (Agreement) for the IngramRichardson Site (the Site) located near

Frankfort, in Clinton County, Indiana,

has been executed by Clinton County,

Indiana (the County), Frankfort Market

Place, Inc. (Frankfort Market Place), and

Kelly Strange (Mr. Strange). The

proposed Agreement has been

submitted to the Attorney General for

approval. The proposed Agreement

would resolve certain potential claims

of the United States under sections 106

and 107 of CERCLA, 42 U.S.C. 9606 and

9607, against the County, as the

prospective purchaser of the Site. The

proposed Agreement also would resolve

the potential liability of Frankfort

Market Place and Mr. Strange (who are

alleged to be past and current owners

and operators of the Site) under

CERCLA section 107 for certain past

response costs incurred in connection

with the Site, pursuant to the

administrative cost recovery settlement

authority conferred by CERCLA section

122(h)(1), 42 U.S.C. 9622(h)(1).

The components of the proposed

Agreement relating to the County would

require the County to pay $7,500 to the

United States and to demolish unusable

buildings on the Site before

redeveloping the Site for use as a

residential treatment center for

juveniles. The United States would

remove the CERCLA lien currently

placed on the Site property. The components of the proposed

Agreement relating to Frankfort Market

Place and Mr. Strange provide that: (1)

Frankfort Market Place and Mr. Strange

will pay $7,500 to the United States, to

be applied toward more than $2.789

million in unreimbursed past response

costs incurred in connection with

removal action undertaken at the Site;

(2) Frankfort Market Place and Mr.

Strange will convey their ownership

interest in the Site to the County, at no

cost to the County; and (3) the United

States will grant Frankfort Market Place

and Mr. Strange a covenant not to sue

for past response costs incurred in

connection with the removal action (and

will dismiss without prejudice a

pending, unanswered civil judicial

complaint filed by the United States

against Frankfort Market Place under

CERCLA section 107), and those parties

will obtain contribution protection as

provided by CERCLA sections 113(f)(2)

and 122(h)(4) upon satisfactory

completion of their obligations under

the Agreement. The Site is not on the NPL, and no

further response activities at the Site are

anticipated at this time.

DATES: Comments on the proposed

Agreement must be received by July 23,

1998.

ADDRESSES: A copy of the proposed

Agreement is available for review at

U.S. EPA, Region 5, 77 West Jackson

Boulevard, Chicago, Illinois 60604.

Counsel, U.S. EPA, Region 5, 77 West

Jackson Boulevard, (Mail Code C–14J),

Chicago, Illinois 60604.
