SUPPLEMENTARY INFORMATION:
Executive Order 12372
This 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 entitled,
``Department Programs and Activities Excluded from Executive Order
12372,'' (50 FR 47034) exempted RUS loans and loan guarantees from
coverage under this order.
Executive Order 12866
This rule has been determined to be not significant for purposes of
Executive Order 12866 and therefore has not been reviewed by OMB.
Executive Order 12778
This rule has been reviewed under Executive Order 12778, Civil
Justice Reform. RUS has determined that this rule meets the applicable
standards provided in sec. 3. of the Executive Order.
Regulatory Flexibility Act Certification
The Administrator of RUS has determined that a rule relating to the
RUS electric loan program is not a rule as defined in the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.) and, therefore, the Regulatory
Flexibility Act does not apply to this final rule.
Information Collection and Recordkeeping Requirements
This rule contains no reporting or recordkeeping provisions
requiring Office of Management and Budget (OMB) approval under the
Paperwork Reduction Act of 1995 (44 U.S.C. chapter 35.)
National Environmental Policy Act Certification
The Administrator of RUS has determined that this 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 number 10.850,
Rural Electrification Loans and Loan Guarantees. This catalog is
available on a subscription basis from the Superintendent of Documents,
United States Government Printing Office, Washington, DC 20402-9325.
Unfunded Mandates
This 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 rule is
not subject to the requirements of section 202 and 205 of the Unfunded
Mandates Reform Act.
Background
RUS amends 7 CFR chapter XVII, part 1728, Electric Standards and
Specifications for Materials and Construction, by revising RUS Bulletin
50-1, Electric Transmission Specifications and Drawings, 115 kV to 230
kV, and RUS Bulletin 50-2, Electric Transmission Specifications and
Drawings, 34.5 kV to 69 kV, and renumbering them as Bulletins 1728F-811
and 1728F-810, respectively.
[[Page 11590]]
The Rural Utilities Service (RUS) maintains bulletins that contain
construction standards and specifications for materials and equipment.
In accordance with the RUS standard form of loan documents, these
standards and specifications apply to systems constructed by RUS
electric and telecommunications borrowers, and contain standard
construction units, material, and equipment units used on RUS electric
and telephone borrowers' systems. Bulletins 50-1 and 50-2 establish
standard overhead electric transmission construction drawings and
specifications for wood pole structures and assemblies for use by RUS
borrowers on electric systems.
RUS changes the bulletin numbers from Bulletins 50-1 and 50-2 to
Bulletins 1728F-811 and 1728F-810, respectively. The changes in the
bulletin number and reformatting of the specifications were necessary
to conform to RUS' publications and directives system. In addition,
certain changes were made to clarify the drawings and specifications.
Changes were made for some of the drawings that appear in the current
bulletins. These drawing changes are summarized below. If no changes
were made to the drawings, the unchanged drawings remain the same as in
the current bulletin except that the final rule effective date will be
added for publication and verification purposes. The final rule
effective date will also be added to the drawings for which changes
were made.
Copies of the bulletins will be available for purchase from
Superintendent of Documents, P.O. Box 371954, Pittsburgh, PA 15250-
7954, telephone (202) 512-1800.
Corrections were made to Crossarm Drilling Drawings TCD-11, TCD-15,
TCD-20 and TCD-32 of bulletins formerly designated as Bulletin 50-2 and
50-1, renumbered as Bulletins 1728F-810 and 1728F-811. Several
dimensions which are used to drill the crossarms were corrected on
crossarm drilling drawings. Crossarm types 81 and 83 (5\1/8\'' x 7\1/
2\'') are eliminated on drawing TCD-40, since laminated arms are
readily available in standard 9\3/8\'' x 3\5/8\'' sizes.
Drawing TG-15 and TG-45 were revised to show the minimum thickness
and width of the guying plate. Drawing TG-16 and TG-46 were revised to
a better ground the connection between the guy wire and the pole ground
wire. On drawing TG-17, a guying plate is added to TG-17D where the
insulators attach to the pole and anchor shackles have been added to
TG-17E. The anchor shackles are necessary to permit the attachment of
light duty guy assemblies to the double eye pole eye plate. The
capacity of the swing angle bracket shown on drawing TG-18 is being
clarified to show both allowable and ultimate capacities. Washers are
being added on the clevis side of the clevis bolts. These washers will
provide a bearing surface when tightening the nut to the clevis bolt.
The dimensions of the connecting links to the pole bands were removed
from drawing TG-26, Guy Attachments (Pole Bands) and TG-46, Pole Tie
Assemblies (Pole Bands). The size of the link depends on the strength
of the metal used by different manufacturers.
Drawings TG-28 and TG-29, Bracket and Guy Attachment, were revised
to show minimum sizes for the bracket and to clarify the notes by
adding an allowable vertical load and defining the ultimate load to be
compatible with the TH-10 series structures and TG-29. Antisplit bolts
were added to drawings TG-35D and TG-35E, Heavy Duty Guying Ties.
Several notes have been added to TG-36, Heavy Duty Pole Bands, so that
problems associated with improper use of this unit are avoided. Since
there are no suppliers for heavy duty pole eye plates, drawing TG-37 is
eliminated. The pole tie assemblies shown in drawing TG-47 are modified
to be similar to TG-45.
Units TM-1B and TM-2B of drawings TM-1 and TM-2, Insulator Assembly
Units, were modified in both bulletins to require the use of a Y-clevis
ball instead of the anchor shackle and oval eye ball. The use of a Y-
clevis ball will provide savings to the RUS borrower. It is a standard
hardware item that has been used frequently on steel and concrete pole
construction.
The Pole Stablility, Bearing, and Uplift Foundations drawings (TM-
101, 102, 103) were revised to eliminate the compacted backfill below
the pole for TM-101 unit, to eliminate unit TM-102B, and to add a note
to the engineer on TM-103. All three drawings show the backfill at
ground level in a more realistic manner. The reason for the proposed
elimination of unit TM-102B is the difficulty in compacting the soil
below the top pair of pole bearing plates. The crossarm splice (TM-
114A) was eliminated since laminated arms are readily available. Note 4
to Drawing TM-111 was revised for clarification. Drawing TM-115, Steel
Upswept Arm Assembly, was revised to show Table 1, Required Dimensions
and Swing Angle Clearances. A dimension for the 50,000 pound anchor
shackle has been corrected on Drawing TM-120, Hardware.
RUS eliminated the higher capacity log anchors (TA-3L, 3LC, 5L, and
5LC) from the log anchor drawings of both bulletins. The size of the
washer required in these construction units limits the safety factor
below those designated for other assemblies. The other log anchor units
remain in both bulletins (TA-2L and TA-4L). On these drawings, as well
as drawing TA-2P, average soil is redefined as class 5 soil to be
consistent with other RUS publications.
The modification to existing drawings TA-1S through TA-24S, Anchors
(Power Screw), in both bulletins was suggested by RUS borrowers and
their consulting engineers. This revision simplifies defining unit
costs for screw anchors. Screw anchor units will be composed of the
basic helix section with a 5-foot extension . A bid unit will cover the
number of extensions. The new drawing is designated TA-2H to 4H.
Corrections to the list of materials for the TSS-9 structure in
Bulletin 1728f-810 shows a 12'-0'' arm for the lower crossarm instead
of 9'-0'' arm. The pole ground wire was relocated on the TS-1B, TS-1BX,
TS-1C, TSZ-115B, TSZ-138B, TS-115B, and TS-138B in order to improve the
BIL (Basic Impulse Insulation Level) of the structure.
Drawings TPF-40 and TPF-50 were revised to reflect the option of
using adjustable spacers with gained poles. A corresponding change is
included in the list of options in the construction specifications.
On November 8, 1996, RUS published a proposed rule (61 Fed. Reg.
57788) to revise its specifications and drawings for 34.5 kV to 230 kV
transmission lines. Comments on this proposed rule were due January 7,
1997. No comments were received.
