7 CFR Part 1755
RUS Specification for Telecommunications Conduit
AGENCY: Rural Utilities Service, USDA.
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Rural Utilities Service (RUS) proposes to amend its
regulations on Telecommunications Standards and Specifications for
Materials, Equipment, and Construction, by adding a new specification,
RUS Specification for Telecommunications Conduit. The specification
will provide the relevant engineering and technical requirements for
conduit.
DATES: Comments concerning this proposed rule must be received by RUS
or be postmarked no later than January 4, 1999.
ADDRESSES: Comments should be mailed to Orren E. Cameron, III,
Director, Telecommunications Standards Division, Rural Utilities
Service, U.S. Department of Agriculture, 1400 Independence Avenue, SW.,
STOP 1598, Washington, DC 20250-1598. RUS requests an original and
three copies of all comments (7 CFR part 1700.4). All comments received
will be made available for public inspection at room 2835, South
Building, U.S. Department of Agriculture, 1400 Independence Avenue, SW,

SUPPLEMENTARY INFORMATION:
Executive Order 12866
This proposed rule is exempt from the Office of Management and
Budget (OMB) review for purposes of Executive Order 12866.
Executive Order 12988
This proposed rule has been reviewed under Executive Order 12988,
Civil Justice Reform. RUS has determined that this rule meets the
applicable standards provided in section 3 of the Executive Order. In
addition, all state and local laws and regulations that are in conflict
with this rule will be preempted, no retroactive effort will be given
to this rule, and, in accordance with Sec. 212(c) of the Department of
Agriculture Reorganization Act of 1994 (7 U.S.C. 6912(c)), appeal
procedures must be exhausted before an action against the Department or
its agencies may be initiated.
Regulatory Flexibility Act Certification
The Administrator of RUS has determined that this proposed rule
will not have a significant 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 short-term direct costs to the RUS borrower. However,
the long-term direct economic costs are reduced through greater
durability and lower maintenance cost over time.
Information Collection and Recordkeeping Requirements
The information collection and recordkeeping requirements contained
in this proposed rule were approved by OMB pursuant to the Paperwork
Reduction Act of 1995 (44 U.S.C. Chapter 35, as amended) under control
number 0572-0059. Comments concerning these requirements should be
directed to F. Lamont Heppe, Jr., Director, Program Development and
Regulatory Analysis, USDA, RUS, Stop 1522, Washington, DC 20250-1522.
National Environmental Policy Act Certification
The Administrator of RUS has determined that this proposed rule
will not significantly affect the quality of the human environment as
defined by the National Environmental Policy Act of 1969 (42 U.S.C.
4321 et seq.). Therefore, this action does not require an environmental
impact statement or assessment.
Catalog of Federal Domestic Assistance
The program described by this proposed rule is listed in the
Catalog of Federal Domestic Assistance programs under No. 10.851, Rural
Telephone Loans and Loan Guarantees, and No. 10.582, Rural Telephone
Bank Loans. This catalog is available on a subscription basis from the
Superintendent of Documents, United States Government Printing 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 final rule related notice titled
``Department Programs and Activities Excluded from Executive Order
12372'' (50 FR 47034) determined that RUS and RTB loans and loan
guarantees, were not covered by Executive Order 12372.
Unfunded Mandates
This proposed rule contains no federal mandates (under the
regulatory provision of Title II of the Unfunded Mandates Reform Act)
for State, local, and tribal governments or the private sector. Thus
this proposed rule is not subject to the Unfunded Mandates Reform Act.
Background
Pursuant to the Rural Electrification Act of 1936, as amended, (7
U.S.C. et seq.) (RE Act), RUS makes and guarantees loans to furnish and
improve telecommunications in rural areas. As a condition of financing,
borrowers are required to follow RUS standards and specifications for
the construction of RUS financed facilities.
The specification contains mechanical and environmental
requirements, desired design features, and test methods for evaluation
of conduit. The test method procedures described in the specification
are required to demonstrate the reliability of conduit for use in
telecommunications systems.
Conduit is fabricated from rigid and flexible plastic, concrete, or
fiberglass. Conduit comes in different sizes and configurations to suit
a variety of applications. The purpose of conduit is to provide
protection of telecommunications cable and provide ease of installation
in restrictive areas.

permeable to water in excess of 38.5 cubic in. (63.1*E+04 cubic mm) per
hour as determined in an outside corner chamber of the multi-duct. The
test specimens for this test shall be in units of conduit at least 36
in. (914 mm) in nominal length which have been dried at a temperature
of approximately 70 deg.F (21 deg.C) for a period of not less than 24
hours. A total of 5 test specimens shall be prepared in this manner. A
rubber duct plug or equivalent shall then be used to seal the chamber
to be tested. Water at a temperature of approximately 70 deg.F
(21 deg.C) shall be poured into the sealed chamber to a height of 34
in. (864 mm) from the sealed end of the chamber. The water level shall
not fall more than 2 in. (51 mm) in 30 minutes for each of the tested
specimens.
(ii) Compressive strength. Compressive strength tests shall be made
on a total of 5 specimens of 12 in. (305 mm) in nominal length cut from
full length units of conduit but not including any formed end.
Specimens shall be air dried at a temperature of approximately 70 deg.F
(21 deg.C) for a period of not less than 24 hours immediately prior to
the test. Samples shall be tested, 6-duct resting on the wide side, as
follows. A suitable container, having interior dimensions of not less
than 14 in. (356 mm) in length and 14 in. (356 mm) in width, shall be
filled to a depth of not less than 2 in. (51 mm) nor more than 4 in.
(102 mm) with dry, tightly packed sand and placed on the lower platen
of the testing machine. The test specimen shall be bedded on the sand
so that its upper surface is parallel with the crosshead of the test
machine. The upper bearing block shall consist of a rigid steel plate
14 in. (356 mm) square and not less than \1/2\ in. (13 mm) thick and
shall be positioned so that it overhangs the flat portion of the upper
surface of the sample on all sides. A sheet of sponge rubber 1 in. (25
mm) thick and 14 in. (356 mm) square, or equivalent, shall be inserted
between the bearing block and the specimen. The load shall then be
applied at a uniform rate such that the minimum compressive value set
forth in Table 4 is reached in not less than 1 minute. No sample shall
fail at a load less than that shown in Table 4. A sample shall be
considered to have failed upon the first evidence that cracking has
occurred. Table 4 is as follows:
