Discussion

The Direction Ge ́ne ́rale de l’Aviation

Civile (DGAC), which is the

airworthiness authority for France,

notified the FAA that an unsafe

condition may exist on certain Airbus

Model A330 and A340 series airplanes.

The DGAC advises that, during fatigue

testing on a test article, cracks were

found at the rib 1/center spar angle and

bottom corner fitting. Certain cracks (in

the bottom corner fitting and the vertical

angle) were attributed to local bending.

Such cracking, if not corrected, could

result in reduced structural capability of

the wing.

Explanation of Relevant Service

Information

Airbus has issued Service Bulletins

A330–57–3017 including Appendix 01,

Revision 02, dated October 11, 1999 (for

Model A330 series airplanes); and

A340–57–4022 including Appendixes

01 and 02, dated October 8, 1999 (for

Model A340 series airplanes). These

service bulletins describe procedures for

modification of the rib 1/wing center

spar attachment. The modification

involves:

• Installing washers on the bottom

corner fitting of the wing center spar to

reduce local bending when a tension

load is applied through the fasteners,

and

• Installing a new vertical angle with

a reduced thickness to reduce the stress

generated in the angle.

Accomplishment of the actions

specified in the service bulletins is

intended to adequately address the

identified unsafe condition. The DGAC

classified these service bulletins as

mandatory and issued French

airworthiness directives 2000–073–

111(B), dated February 23, 2000, and

2000–074–136(B), both dated February

23, 2000, in order to ensure the

continued airworthiness of these

airplanes in France.

FAA’s Conclusions

These airplane models are

manufactured in France and are type

certificated for operation in the United

States under the provisions of section

21.29 of the Federal Aviation

Regulations (14 CFR 21.29) and the

applicable bilateral airworthiness

agreement. Pursuant to this bilateral

airworthiness agreement, the DGAC has

kept the FAA informed of the situation

described above. The FAA has

examined the findings of the DGAC,

reviewed all available information, and

determined that AD action is necessary

for products of this type design that are

certificated for operation in the United

States.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design registered in the United

States, the proposed AD would require

accomplishment of the actions specified

in the service bulletins described

previously.

Cost Impact

The following information describes

the anticipated cost impact on U.S.

operators for the proposed modification.

Model

Number of airplanes on U.S.

Register

Number of

work hours

Average labor

rate per work

hour

Cost of

required

parts

Per-airplane

cost

A330 ..................................................................................... 5 42 $60 $9,950 $12,470

A340 ..................................................................................... 0 42 60 10,099 12,619

The cost impact figures discussed

above are based on assumptions that no

operator has yet accomplished the

modification of this proposed AD, and

that no operator would accomplish

these actions in the future if this AD

were not adopted. However, the FAA

has been advised that the 5 airplanes

currently on the U.S. Register have been

modified in accordance with the

proposed requirements. Therefore, until

additional affected airplanes

(unmodified) are added to the U.S.

Register, this proposed AD would

impose no cost on U.S. operators.

The cost impact figures discussed in

AD rulemaking actions represent only

the time necessary to perform the

specific actions actually required by the

AD. These figures typically do not

include incidental costs, such as the

time required to gain access and close

up, planning time, or time necessitated

by other administrative actions.

Regulatory Impact

The regulations proposed herein

would not have a substantial direct

effect on the States, on the relationship

between the national Government and

the States, or on the distribution of

power and responsibilities among the

various levels of government. Therefore,

it is determined that this proposal

would not have federalism implications

under Executive Order 13132.

For the reasons discussed above, I

certify that this proposed regulation (1)

is not a ‘‘significant regulatory action’’

under Executive Order 12866; (2) is not

a ‘‘significant rule’’ under the DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979); and (3) if

promulgated, will not have a significant

economic impact, positive or negative,

on a substantial number of small entities

under the criteria of the Regulatory

Flexibility Act. A copy of the draft

regulatory evaluation prepared for this

action is contained in the Rules Docket.

A copy of it may be obtained by

contacting the Rules Docket at the

40 CFR Part 261

[SW–FRL–6878–3]

Hazardous Waste Management

System; Proposed Exclusion for

Identification and Listing Hazardous

Waste

AGENCY: Environmental Protection

Agency, (EPA).

ACTION: Proposed rule and request for

comment.

SUMMARY: The EPA (also, ‘‘the Agency’’

or ‘‘we’’ in this preamble) is proposing

to grant a petition submitted by USG

Corporation (USG), Chicago, Illinois, to

exclude (or ‘‘delist’’), on a one-time

basis, certain solid wastes that are

interred at an on-site landfill at its

American Metals Corporation (AMC)

facility in Westlake, Ohio from the lists

of hazardous wastes contained in

Subpart D of 40 Code of Federal

Regulations (CFR) Part 261. This landfill

was used exclusively by Donn

Corporation, the original site owner, for

disposal of its wastewater treatment

plant (WWTP) sludge from 1968 to

1978.

USG submitted the petition under 40

CFR 260.20 and 260.22(a). Section

260.20 allows any person to petition the

Administrator to modify or revoke any

provision of parts 260 through 266, 268

and 273. Section 260.22(a) specifically

provides a generator the opportunity to

petition the Administrator to exclude a

waste on a ‘‘generator specific’’ basis

from the hazardous waste lists.

The Agency has tentatively decided to

grant the petition based on an

evaluation of waste-specific information

provided by USG. This proposed

decision, if finalized, conditionally

excludes the petitioned waste from the

requirements of hazardous waste

regulations under the Resource

Conservation and Recovery Act (RCRA).

We conclude that USG’s petitioned

waste is nonhazardous with respect to

the original listing criteria or factors

which could cause the waste to be

hazardous.

DATES: Comments. We will accept

public comments on this proposed

decision until November 13, 2000. We

will stamp comments postmarked after

the close of the comment period as

‘‘late.’’ These ‘‘late’’ comments may not

be considered in formulating a final

decision.

Request for Public Hearing. Your

request for a hearing must reach EPA by

October 12, 2000. The request must

contain the information prescribed in

§ 260.20(d).

ADDRESSES: Comments. Please send two

copies of your comments to Todd

Ramaly, Waste Management Branch

(DW–8J), Environmental Protection

Agency, 77 W. Jackson Blvd., Chicago,

IL 60604.

Request for Public Hearing. Any

person may request a hearing on this

proposed decision by filing a request

with Robert Springer, Director, Waste,

Pesticides and Toxics Division,

Environmental Protection Agency, 77

W. Jackson Blvd., Chicago, IL 60604.

FOR FURTHER INFORMATION CONTACT: For

technical information concerning this

document, contact Todd Ramaly at the
