SUPPLEMENTARY INFORMATION:
Executive Order 12866
This proposed rule has been determined to be not significant and
therefore has not been reviewed by the Office of Management and Budget.
Executive Order 12778
This proposed rule has been reviewed under Executive Order 12778,
Civil Justice Reform. If adopted, this proposed rule will not:
(1) Preempt any State or local laws, regulations, or policies;
(2) Have any retroactive effect; and
(3) Require administrative proceedings before parties may file suit
challenging the provisions of this rule.
Regulatory Flexibility Act Certification
The Administrator of RUS has determined that this proposed rule
will not have a significant economic impact on a substantial number of
small entities, as defined by the Regulatory Flexibility Act (5 U.S.C.
601 et seq.). This proposed rule involves standards and specifications,
which may increase the direct short-term costs to RUS borrowers.
However, the long-term direct economic costs are reduced through
greater durability and lower maintenance cost over time.
Information Collection and Recordkeeping Requirements
The reporting and recordkeeping requirements contained in the
proposed rule were approved by the Office of Management and Budget
(OMB) pursuant to the Paperwork Reduction Act of 1995 (44 U.S.C.
Chapter 35, as amended) under control number of 0572-0059.

Office, Washington, DC 20402.
Executive Order 12372
This proposed rule is excluded from the scope of Executive Order
12372, Intergovernmental Consultation, which may require consultation
with State and local officials. A Notice of Final rule titled
Department Programs and Activities Excluded from Executive Order 12372
(50 FR 47034) exempts RUS and RTB loans and loan guarantees, and RTB
bank loans, to governmental and nongovernmental entities from coverage
under this Order.
Background
RUS issues publications titled ``Bulletin'' which serve to guide
borrowers regarding already codified policy, procedures, and
requirements needed to manage loans, loan guarantee programs, and the
security instruments which provide for and secure RUS financing. RUS
issues standards and specifications for the construction of telephone
facilities financed with RUS loan funds. RUS Bulletin 345-36, ``RUS
Specification for Parallel Conductor Drop Wire,'' PE-7, dated January
25, 1983 presently contains the engineering and technical requirements
for aerial service wires that are considered necessary for satisfactory
performance in outside plant environments. Because of the technological
advancements made in aerial service wire designs over the past eleven
years, RUS proposes to incorporate and update the information contained
in RUS Bulletin 345-36 into 7 CFR 1755.700 through 7 CFR 1755.704, RUS
Specification for Aerial Service Wires, and to rescind RUS Bulletin
345-36 upon the effective date of 7 CFR 1755.700 through 7 CFR
1755.704.
The specification allows aerial service wire designs consisting of
one pair through six pairs. The specification also allows aerial
service wire designs
[[Page 67341]]
containing copper coated steel and nonmetallic reinforcing members.
The specification contains mechanical, electrical, and
environmental requirements, and test methods for evaluation of these
aerial service wire designs.
This action establishes RUS requirements for a wider range of
aerial service wires without affecting current designs or manufacturing
techniques. This wider selection of aerial service wires will afford
RUS telephone borrowers the opportunity to increase subscriber services
in an economical and efficient manner through enhanced wire designs
brought about by technological advancements made during the past eleven
years.
