organophosphates, carbamates,

pyrethroids, benzoylureas, and other

diacylhydrazines. Thus, there is no

evidence to date to suggest that

cumulative effects of tebufenozide and

other chemicals should be considered.

E. Safety Determination

1. U.S. population. Using the

conservative exposure assumptions

described above and taking into account

the completeness and reliability of the

toxicity data, the dietary exposure to

tebufenozide from the current and

future tolerances will utilize 20.1% of

the RfD for the U.S. population and

52.0% for non-nursing infants under 1–

year old. Using anticipate residue levels

for these crops utilizes 3.38% of the RfD

for the U.S. population and 12.0% for

non-nursing infants. EPA generally has

no concern for exposures below 100%

of the RfD because the RfD represents

the level at or below which daily

aggregate dietary exposure over a

lifetime will not pose appreciable risks

to human health. Rohm and Haas

concludes that there is a reasonable

certainty that no harm will result from

aggregate exposure to tebufenozide

residues to the U.S. population and nonnursing infants.

2. Infants and children. In assessing

the potential for additional sensitivity of

infants and children to residues of

tebufenozide, data from developmental

toxicity studies in the rat and rabbit and

two 2-generation reproduction studies

in the rat are considered. The

developmental toxicity studies are

designed to evaluate adverse effects on

the developing organism resulting from

pesticide exposure during pre-natal

development to one or both parents.

Reproduction studies provide

information relating to effects from

exposure to the pesticide on the

reproductive capability of mating

animals and data on systemic toxicity.

Developmental toxicity was not

observed in developmental studies

using rats and rabbits. The NOEL for

developmental effects in both rats and

rabbits was 1,000 mg/kg/day, which is

the limit dose for testing in

developmental studies.

In the 2–generation reproductive

toxicity study in the rat, the

reproductive/ developmental toxicity

NOEL of 12.1 mg/kg/day was 14-fold

higher than the parental (systemic)

toxicity NOEL (0.85 mg/kg/day). The

reproductive (pup) LOEL of 171.1 mg/

kg/day was based on a slight increase in

both generations in the number of

pregnant females that either did not

deliver or had difficulty and had to be

sacrificed. In addition, the length of

gestation increased and implantation

sites decreased significantly in F1 dams.

These effects were not replicated at the

same dose in a second 2–generation rat

reproduction study. In this second

study, reproductive effects were not

observed at 2,000 ppm (the NOEL equal

to 149-195 mg/kg/day) and the NOEL for

systemic toxicity was determined to be

25 ppm (1.9-2.3 mg/kg/day).

Because these reproductive effects

occurred in the presence of parental

(systemic) toxicity and were not

replicated at the same doses in a second

study, these data do not indicate an

increased pre-natal or post-natal

sensitivity to children and infants (that

infants and children might be more

sensitive than adults) to tebufenozide

exposure. FFDCA section 408 provides

that EPA shall apply an additional

safety factor for infants and children in

the case of threshold effects to account

for pre- and post-natal toxicity and the

completeness of the data base unless

EPA concludes that a different margin of

safety is appropriate. Based on current

toxicological data discussed above, an

additional uncertainty factor is not

warranted and the RfD at 0.018 mg/kg/

day is appropriate for assessing

aggregate risk to infants and children.

Rohm and Haas concludes that there is

a reasonable certainty that no harm will

occur to infants and children from

aggregate exposure to residues of

tebufenozide.

F. International Tolerances

There are no approved CODEX

maximum residue levels (MRLs)

established for residues of tebufenozide.

SUPPLEMENTARY INFORMATION:

I. EPA’s Process for Developing a

Unified Library of Test Guidelines

EPA’s Office of Prevention, Pesticides

and Toxic Substances (OPPTS) has been

engaged in a multi-year project to

harmonize and/or update test guidelines

among the Office of Pesticide Programs

(OPP), the Office of Pollution

Prevention and Toxics (OPPT), and the

Organization for Economic Cooperation

and Development (OECD). The goals of

the project include the formulation of
4260 Federal Register / Vol. 63, No. 18 /Wednesday, January 28, 1998 / Notices

harmonized OPP and OPPT guidelines

for those in common between the two

programs, the harmonization of OPPT

and/or OPP guidelines with those of the

OECD, the updating of any guidelines

unique to OPP or OPPT programs, and

the addition of several new guidelines.

Testing guidelines that are changed

substantively in the harmonization

process or through other updating/

amending activities, or which are new

(e.g., for a previously unaddressed

testing endpoint) will be made available

for public comment by notice in the

Federal Register. Additionally, EPA

submits substantively revised and new

test guidelines to peer review by expert

scientific panels. Guidelines which are

reformatted but not changed in any

substantive way are not made available

for public comment or submitted to peer

review.

All final guidelines will be made

available through the GPO Electronic

Bulletin Board and the Internet on the

EPA World Wide Web home page as a

unified library of OPPTS Test

Guidelines for use by either EPA

program office. Printed versions of the

unified library of OPPTS test guidelines

will also be available to the public

through the GPO. For purposes of this

Federal Register notice, ‘‘publication’’

of the unified library of guidelines

generally describes the availability of

these final guidelines through the GPO

and Internet. Because harmonization

and updating is an ongoing task that

will periodically result in modified

guidelines, some guidelines being made

available via GPO and Internet will be

revised in the future. These efforts will

ensure that industry is provided with

testing guidelines that are current.

The test guidelines appearing in the

unified library will be given numerical

designations that are different from the

designations provided at 40 CFR parts

158, 795, 796, 797, 798, and 799. OPPTS

test guidelines will be published in 10

disciplinary series as follows:

Series 810—Product Performance Test

Guidelines

Series 830—Product Properties Test

Guidelines

Series 835—Fate, Transport and

Transformation Test Guidelines

Series 840—Spray Drift Test

Guidelines

Series 850—Ecological Effects Test

Guidelines

Series 860—Residue Chemistry Test

Guidelines

Series 870—Health Effects Test

Guidelines

Series 875—Occupational and

Residential Exposure Test Guidelines

Series 880—Biochemicals Test

Guidelines

Series 885—Microbial Pesticide Test

Guidelines

The Agency issues Federal Register

notices periodically announcing any

new test guidelines added to the OPPTS

unified library. As each set of guidelines

is published, it will be accompanied by

a Master List which cross references the

new OPPTS guideline numbers to the

original OPP and OPPT numbers.

II. Series 835 Changes

Significant changes to the Series 835

test guidelines include addition of a

new guideline, Biodegradability in Sea

Water, in OPPTS 835.3160;

recommendation of the alkali addition

method in the Sealed Vessel Carbon

Dioxide Production Test in OPPTS

835.3120; clarification of guideline

scope with respect to redox conditions

and recommendation of field

temperature incubation in the

Sediment/Water Microcosm

Biodegradation Test in OPPTS

835.3180; discussion of the importance

of maintaining influent dissolved

organic carbon (DOC) levels and

addition of language to permit periodic

wastage of sludge in the Porous Pot Test

in OPPTS 835.3220; and discussion of

evidence supporting the contention that

treated (deactivated) sludge retains the

characteristics of viable sludge in the

Activated Sludge Sorption Isotherm

Test in OPPTS 835.1110. In addition,

test guideline OPPTS 835.3400,

Anaerobic Biodegradability of Organic

Chemicals, is retained despite several

negative comments on the method.

Major revisions to this protocol are

presently being considered in several

fora (ASTM; ISO; OECD) and EPA

intends to revisit this topic when

consensus is reached on certain

technical issues. Explicit test

requirements for pesticide registration

are set out in 40 CFR part 158 which

refers to specific guidelines by guideline

number. Studies initiated 45 days or

more after final publication should be

performed in accordance with the

revised guidelines.

III. Public Record

A detailed description of the response

to comments and the changes to each

guideline are available under docket

COMMISSION

Notice of Public Information Collection

Submitted to OMB for Review and

Approval

January 16, 1998.

SUMMARY: The Federal Communications

Commission, as part of its continuing

effort to reduce paperwork burden

invites the general public and other

Federal agencies to take this

opportunity to comment on the

following information collection, as

required by the Paperwork Reduction

Act of 1995, Public Law 104–13. An

agency may not conduct or sponsor a

collection of information unless it

displays a currently valid control

number. No person shall be subject to

any penalty for failing to comply with

a collection of information subject to the

Paperwork Reduction Act that does not

display a valid control number.

Comments should address: (a) Whether

the proposed collection of information

is necessary for the proper performance

of the functions of the Commission,

including whether the information shall

have practical utility; (b) the accuracy of

the Commission’s burden estimates; (c)

ways to enhance the quality, utility, and

clarity of the information collected; and

(d) ways to minimize the burden of the

collection of information on the

respondents, including the use of

automated collection techniques or

other forms of information technology.

DATES: Written comments should be

submitted on or before February 27,

1998. OMB Notification of Action is due

on or before March 30, 1998. If you

anticipate that you will be submitting

comments, but find it difficult to do so

within the period of time allowed by

this notice, you should advise the

contact listed below as soon as possible.

ADDRESSES: Direct all comments to Judy

Boley, Federal Communications, Room

234, 1919 M St., NW., Washington, DC

20554 or via internet to jboley@fcc.gov.

SUPPLEMENTARY INFORMATION: On

October 17, 1997, the Commission

released a Report and Order and Second

Further Notice of Proposed Rulemaking,

FCC 97–376, which addresses rules and

policies concerning cable inside wiring.

Among other things, this rulemaking

amends the Commission’s regulations

relating to the disposition of cable home

wiring and related issues including the

sharing of molding, the demarcation

point for multiple dwelling unit

buildings (‘‘MDUs’’), loop-through cable

wiring configurations, customer access

to cable home wiring before termination

of service, and signal leakage.

OMB Approval Number: 3060–0692.

Title: Home Wiring Provisions.

Type of Review: Revision of a

currently approved collection.

Respondents: Business and other forprofit entities.

Number of Respondents: 30,500

(20,500 multichannel video program

distributors and 10,000 multiple

dwelling unit building owners).

Estimated Time Per Response: 5

minutes–20 hours.

Total Annual Burden to Respondents:

46,114 hours, calculated as follows:

This collection (3060–0692) accounts

for all information collection

requirements that may come into play

during the disposition of cable home

wiring in single dwelling units, as well

as the disposition of home run wiring

and cable home wiring in MDUs. All

multichannel video programming

distributors (‘‘MVPDs’’), both cable and

non-cable alike, are now subject to these

disposition rules. Pursuant to the

Paperwork Reduction Act, when

modifying only portions of an

information collection, agencies are still

obligated to put forth the entire

collection for public comment.

This information collection now

accounts for the information collection

requirement stated in 47 CFR 76.613,
