Federal Register / Vol. 70, No. 76 / Thursday, April 21, 2005 / Rules and Regulations
be released to the free and restricted
markets each marketing year. The
program results in plentiful supplies for
consumers and for market expansion
while retaining the mechanism for
dealing with oversupply situations.
Hazelnuts produced under the order
comprise virtually all of the hazelnuts
produced in the U.S. This production
represents, on average, less than 4
percent of total U.S. production for
other tree nuts, and less than 5 percent
of the world’s hazelnut production.
Last season, 79 percent of the kernels
were marketed in the domestic market
and 21 percent were exported.
Domestically produced kernels
generally command a higher price in the
domestic market than imported kernels.
The industry is continuing its efforts to
develop and expand other markets with
emphasis on the domestic kernel
market. Small business entities, both
producers and handlers, benefit from
the expansion efforts resulting from this
program.
Inshell hazelnuts produced under the
order compete well in export markets
because of quality. Based on Board
statistics, Europe has historically been
the primary export market for U.S.
produced inshell hazelnuts, with a 10year average of 5,255 tons out of total
average exports of 14,048 tons. Recent
years have seen a significant shift in
export destinations. Last season, inshell
shipments to Europe totaled 5,526 tons,
representing 24 percent of exports, with
the largest share going to Germany.
Inshell shipments to Southwest Pacific
countries, and Hong Kong in particular,
have increased dramatically in the past
few years, rising to 70 percent of total
exports of 23,319 tons in 2003. The
industry continues to pursue export
opportunities.
There are some reporting,
recordkeeping, and other compliance
requirements under the order. The
reporting and recordkeeping burdens
are necessary for compliance purposes
and for developing statistical data for
maintenance of the program. The
information collection requirements
have been previously approved by the
Office of Management and Budget under
OMB No. 0581–0178. The forms require
information which is readily available
from handler records and which can be
provided without data processing
equipment or trained statistical staff. As
with all Federal marketing order
programs, reports and forms are
periodically reviewed to reduce
information requirements and
duplication by industry and public
sector agencies. This rule does not
change those requirements. In addition,
USDA has not identified any relevant
VerDate jul<14>2003
16:25 Apr 20, 2005
Jkt 205001
Federal rules that duplicate, overlap or
conflict with this rule.
Further, the Board’s meetings were
widely publicized throughout the
hazelnut industry and all interested
persons were invited to attend the
meetings and participate in Board
deliberations. Like all Board meetings,
those held on August 26, and November
3, 2004, were public meetings and all
entities, both large and small, were able
to express their views on this issue.
An interim final rule concerning this
action was published in the Federal
Register on December 21, 2004. Copies
of this rule were mailed by the Board’s
staff to all Board members. In addition,
the rule was made available through the
Internet by the Office of the Federal
Register and USDA. A 60-day comment
period ending February 22, 2005, was
provided to allow interested parties to
respond to the rule.
Two comments were received during
the comment period in response to the
interim final rule. Both commenters
opposed the action as a restriction of
free trade that artificially inflates prices.
USDA disagrees with the commenters.
As previously stated, the marketing of
domestic inshell hazelnuts is regulated
by USDA upon the recommendation of
the Board to balance the supply of such
hazelnuts with the demand. The Board
believes that equilibrium in the supply
and demand of domestic inshell
hazelnuts benefits consumers and
improves returns to producers. USDA
guidelines stipulate that the domestic
inshell hazelnut market has at least 110
percent of the prior years’ sales are
available to supply consumers’ needs
and facilitate market expansion. In order
to ensure that the supply is not unduly
restricted, the Board recommended
releasing 115 percent of the estimated
trade demand of inshell hazelnuts to the
domestic market. Even with regulation,
hazelnuts generally trade at price levels
below that of walnuts, almonds, and
pistachios, all of which compete in the
marketplace with hazelnuts.
One of the commenters expressed
concern that taxpayer dollars were used
to cover Board costs. Taxpayer dollars
are not used to fund the Board. Funds
generated from assessments on the
handlers of hazelnuts are used to pay
these costs.
Accordingly, no changes will be made
in the finalization of the interim final
rule based on the comments received.
A small business guide on complying
with fruit, vegetable, and specialty crop
marketing agreements and orders may
be viewed at: https://www.ams.usda.gov/

compliance guide should be sent to Jay

After consideration of all relevant
material presented, including the
information and recommendation
submitted by the Board and other
available information, it is hereby found
that finalizing the interim final rule,
without change, as published in the
Federal Register (69 FR 76385,
December 21, 2004) will tend to
effectuate the declared policy of the Act.

Background
Pursuant to the Rural Electrification
Act of 1936, as amended (7 U.S.C. 901
et seq.), the Rural Utilities Services
(RUS) is amended Title 7 CFR Chapter
XVII, Part 1728, Electric Standards and
Specification for Materials and
Construction, by revising RUS Bulletin
50–3 (D–804), ‘‘Specification and
Drawings for 12.5/7.2 kV Line
Construction.’’ This revised bulletin
will be renumbered as RUS Bulletin
1728F–804 and will be re-titled as,
‘‘Specification and Drawings for 12.47/
7.2 kV Line Construction.’’ RUS
maintains a system of bulletins that
PO 00000
Frm 00007
Fmt 4700
Sfmt 4700
20699
contains construction standards and
specifications for materials and
equipment which must be utilized when
system facilities are constructed by RUS
electric and telecommunication
borrowers in accordance with the RUS
loan contract. These standards and
specifications contain standard
construction units, material, and
equipment units used in RUS electric
and telecommunication borrowers’
systems.
RUS Bulletin 50–3 provides standard
construction drawings and specification
of 12.5/7.2 kV overhead electric
distribution lines. RUS is proposing to
change the bulletin number room RUS
Bulletin 50–3 (Standard D 804) to RUS
Bulletin 1728F–804 (D 804). The change
in the bulletin number and reformatting
is necessary to conform to RUS new
publications and directives system. This
rule will incorporate the bulletin by
reference in 7 CFR 1728.97.
Changes to RUS Bulletin 50–3 (D 804)
RUS has made the following changes
and additions to RUS Bulletin 50–3 (D–
804) renumbering it as Bulletin 1728F–
804:
(1) The new bulletin contains a total
of 382 assemblies. (An assembly is a
construction unit which incorporates
the description and quantity of material
needed to construct the assembly and a
dimensioned schematic diagram
showing how the material needs to be
arranged or assembled to meet RUS
specifications.) Bulletin 50–3 currently
contains a total of 257 assemblies. In
both bulletins, more than one similar
assembly is often depicted on one
drawing.
(2) Of the 382 total assemblies in the
new bulletin, 215 are new assemblies
and 95 of these 215 new assemblies are
new ‘‘narrow profile’’ assemblies. The
drawing numbers and titles of the 215
new assemblies and the 24 new guide
drawings of the new bulletin are
tabulated in Exhibit 4 at the end of new
Bulletin 1728F–804.
(3) Of the 382 total assemblies in the
new bulletin, 167 are standard
assemblies of present Bulletin 50–3 that
are being redrawn, renumbered, and reused in new Bulletin 1728f–804. Of
these 167 re-used assemblies, 94 are
previous standard assemblies with no
material changes, 37 are previous
standard assemblies with only a change
in the number or type of washers, and
36 are previous standard assemblies
with other slight material changes.
(4) The new bulletin also contains 32
new guide drawings and 8 renumbered,
redrawn and thus re-used guide
drawings from Bulletin 50–3. Present
Bulletin 50–3 contains a total of 32
E:\FR\FM\21APR1.SGM

Federal Register / Vol. 70, No. 76 / Thursday, April 21, 2005 / Rules and Regulations
guide drawings. (A guide drawing is a
dimensioned schematic diagram that
shows details of how the material of one
or more assemblies needs to be arranged
or assembled to meet RUS specifications
but does not list the material required
for construction.)
(5) A listing the 167 re-used
assemblies and 8 re-used guide
drawings, with both their old numbers
and their new assigned numbers, and
the required assembly material changes,
are tabulated in new Exhibit 3 at the end
of new Bulletin 1728F–804. Exhibit 3
also lists the 90 assemblies and 24 guide
drawings that are being discontinued
from Bulletin 50–3.
(6) Each of the 382 assemblies and 40
guide drawings in new Bulletin 1728F–
804 are being given a new number in
accordance with the assembly
numbering format as updated by RUS in
1998. In the updated numbering format,
each letter and number in the assembly
or drawing number has a functional
meaning.
(7) New Exhibit 5 at the end of the
new bulletin summarizes the new RUS
assembly numbering format and briefly
explains the meanings of each letter or
number in the new assembly and
drawing numbers.
(8) The assembly drawings, the 19
drawing indexes and Exhibit 3 of new
Bulletin 1728F–804 show the new
assigned assembly numbers and the old
numbers (in parentheses) of the 167 reused assemblies and 8 re-used guide
drawings from present Bulletin 50–3.
RUS allows the borrowers to use either
the old or the new assigned assembly
number, but only for the 167 re-used
standard assemblies and 8 re-used guide
drawings. The borrower is being
required to make the slight material
changes to 73 of the re-used assemblies
and to construct the assemblies as
depicted.
(9) The new bulletin is being
reformatted into 19 separate sections or
categories. Each section contains an
index of drawings and also the
construction drawings of assemblies
designed to perform a similar function.
Several sections contain construction
specifications pertaining to the
assemblies in that section.
(10) New tables are being added in the
new bulletin that define maximum line
angles (contained in Exhibit 1),
permitted unbalanced conductor
tensions on crossarm assemblies
(contained in Exhibit 2), and soil
classification data (contained in Section
F).
(11) Exhibit, 1 being added at the end
of the new bulletin, documents the
formula and data used to determine the
maximum line angles in the tables.
VerDate jul<14>2003
16:25 Apr 20, 2005
Jkt 205001
Also, Exhibit 2, being added at the end
of the new bulletin, documents the
formula and data used to determine
permitted unbalanced conductor
tensions on crossarm assemblies.
(12) Each drawing is being given a
new, uniform, shorter, and more
descriptive title. Each drawing also has
a new, uniform title block that contains,
when applicable, the primary voltage
and number of phases of the depicted
assemblies.
(13) ‘‘Design parameters’’ which
define and usually limit maximum line
angles or mechanical loading (tension)
is being added, when applicable, to the
drawings of the new bulletin.
RUS is discontinuing 90 assemblies
and 24 guide drawings presently
contained in Bulletin 50–3 for one or
more of the following reasons:
• They contain material no longer
accepted by RUS for use by RUS
borrowers,
• Either the spacing or the strength of
the assembly no longer meets the
minimum requirements of RUS or the
rules of the National Electrical Safety
Code (NESC),
• They contain technical errors such
as a neutral conductor support that is
not coordinated with the primary
conductor support,
• They are redundant of other
assemblies or for other reasons may no
longer be needed, or
• They require so many modifications
that it is prudent that they be
discontinued and subsequently replaced
with new assemblies.
RUS also is modifying and adding to
the construction specifications in
present Bulletin 50–3 incorporate the
following significant changes in Bulletin
1728F–804:
(1) Compliance and specific
references to the 2002 Edition of the
NESC,
(2) Definitions of and provisions for
the use of large and extra large
conductors,
(3) Permission to lower the neutral
conductor under specific circumstances,
(4) Requirement to use a washer
under the shoulder of 7.2kV crossarm
pins,
(5) Requirement to use a 3-inch
(minimum) square, curved, washer
abutting the pole for primaries, neutrals
and guys that deadend on poles,
(6) Requirement to multiply applied
loads by the appropriate NESC overload
factors,
(7) Minimum insulated spacing (wood
and fiberglass) between primary
conductors and guys,
(8) Choice of arrester location on
transformer assemblies,

(10) Permission to use stirrups
provided certain given criteria are met,
(11) Permission to insulate guy wires
provided certain given criteria are met,
(12) Permission to modify assembly
drawings without further approval from
RUS within certain given parameters,
and
(13) New rights-of-ways clearing
specifications.
RUS Responses to Comments
On February 12, 2004, RUS published
a proposed rule in the Federal Register
at 69 FR 6926 to incorporate by
reference new Bulletin 1728F–804 into
its rules and regulations. A copy of the
proposed bulletin was made available to
the general public on the RUS website
and through the U.S. mail. Members of
the public were allowed 60 days to
furnish RUS with written comments
regarding the proposed bulletin.
Subsequently, employees of the
following rural electric cooperatives and
other business firms furnished RUS
with written comments, suggestions and
questions regarding the proposed
bulletin:
(1) Adams Electric Cooperative, Inc.
(2) Allgeier, Martin and Associates,
Inc.
(3) Cookson Hills & East Central
Electric Cooperative.
(4) Harrison Rural Electric
Membership Cooperative.
(5) Hi-Line Engineering, LLC.
(6) Minnesota Valley Cooperative
Light and Power.
(7) Morgan County Rural Electric
Association.
(8) National Rural Electric
Cooperative Association.
(9) Northern Neck Electric
Cooperative.
In response to the comments and
suggestions received, RUS has added
the following new assemblies and
drawings to the bulletin:
Fifty-three assemblies with various
combinations of secondary brackets,
swinging clevis’, extension eyebolts and
insulated extension links to the A3, A5,
B3, B5, C3 and C5 series of assemblies
and also added top views of assemblies
to improve clarity, assemblies D1.5N
and D1.5NP to utilize offset neutral
brackets on double circuit, narrow
profile assemblies, equipment
assemblies R3.3 S2.3, Y3.1, and Y3.4,
guide drawing G1.2 (and consequently
deleted some notes and the schematic
diagram on guide drawing G1.1),
transformed the 9 ‘‘tying guides’’ in
Section L into 20 new assemblies,
transformed guide drawings E5.1G and
E:\FR\FM\21APR1.SGM
21APR1
Federal Register / Vol. 70, No. 76 / Thursday, April 21, 2005 / Rules and Regulations
S1.1NG into assemblies, modified
assemblies B4.2 and C4.2 to permit line
angles from 15 to 90 degrees, and
transformed them into guide drawings.
Also in response to the comments and
suggestions received, RUS also made the
following changes and corrections:
(1) Corrected 85 errors and omissions
pertaining to old assembly numbers on
the drawings, indexes, and exhibits,
(2) Changes the guy attachment
location on 24 drawings to be consistent
with all of the other guyed assemblies,
(3) Changed the crossarm attachment
location on 9 drawings so that all
crossarms are installed 18 inches from
the top of the pole on all assemblies to
utilize standard pole drilling and to
accommodate pole top pins when
needed,
(4) Added connectors (item ‘‘p’’) and
jumper wires (item ‘‘av’’) to the material
lists on 18 drawings,
(5) Deleted notes referring to ‘‘tying
guides’’ from 22 assemblies because
they were deemed not useful nor
needed,
(6) Removed the note ‘‘(When Req’d)’’
referring to down guys from 12
drawings and added the same note to 5
drawings for the purpose of accuracy
and consistency,
(7) Added the ANSI class and size of
spool insulator to the design parameters
of the 10 drawings that refer to the
maximum line angles in Tables VI and
VII,
(8) Added or changed the distance
from the face of the pole to the nearest
vertical jumper wired to 19 inches on 8
drawings to comply with the rules of the
NESC,
(9) Added an additional note in the
design parameters utilizing preassembled crossarms (item ‘‘gj’’) to
multiply the manufacturer’s strength
rating by the appropriate NESC strength
factor to determine the permitted
loading on the assembly.
RUS also made the following changes
to specific assembly drawings in
response to the comments and
suggestions received:
• Changed drawing numbers ‘‘A1’’,
‘‘A2’’ and ‘‘N5’’ to be the same as the
assembly numbers on the drawings to be
consistent with all of the other drawing
numbers and removed ‘‘Miscellaneous’’
from the drawing title,
• Eliminating drawing ‘‘A5’’ and
relocated its assemblies to other
drawings,
• Corrected the line angle table
reference errors in the design
parameters on drawings C1.3N, C2.3N
and C2.3N,
• Added a top view to assemblies
A3.1, B3.1 and C3.1,

• Increased the permitted line angle
on assemblies A4.1, B4.1, and C4.1 to
the range of 90 to 175 degrees,
• Deleted the note regarding down
guys on the drawings of assemblies
A3.2, A3.3 and A4.1 because it was
confusing. RUS added information
regarding the proper installation and
location of guys to the ‘‘Specifications
for Guying Assemblies,’’
• Corrected error in design
parameters of drawing of assembly
C6.21 to refer to Note 2,
• Changed the design parameters in
the drawings of assemblies C6.51 and
A2.021 to reference Table B of Exhibit
2,
• Deleted the un-referenced word
‘‘ungrounded’’ from guide drawing
G3.2G,
• Added a note referencing NESC
Table 232–2 to guide drawing K4.1G,
• Added crossarm mounting
hardware to assembly S1.01 and a note
indicating that these switches may be
installed on double deadend crossarm
assemblies,
• Corrected the drafting errors
pertaining to the conductors on
assembly Q1.1 and darkened the
secondary conductors line on drawings
Q1.1, Q2.1 and Q3.1 to improve clarity,
• Added a note to assembly drawings
Q3.2 and Q3.3 requiring customerowned or maintained equipment be
located a minimum for 5 feet from the
assembly,
• Changed the materials on grounding
assembly H1.1 to show the installation
of steel ground wire connecting to the
anchor rod,
• Added a note to drawing Q3.2
recommending PT’s for voltages over
240 volts,
• Added a note to drawing S2.32
indicating that RUS accepted preassembled switches may be used and to
install them according to the
manufacturer’s specifications,
• Added notes to guide drawings
D3.1G and D4.1G to adjust material for
only one neutral attachment
subassembly and that the minimum
clearance between and guy and any
primary conductor shall be 5 feet,
• Modified assembly C5.22 so that the
distance from the neutral to the center
phase conductor is 4 feet, 0 inches,
• Changed the ground clearance to
live parts on assembly drawing Y1.1 to
meet NESC requirements; the ground
clearance to the bottom of the regulator
platform (which does not have braces)
was found to conform to the NESC and
was not changed.
The following are RUS’ responses to
comments, suggestions and questions
that did not result in any additions or
PO 00000
Frm 00009
Fmt 4700
Sfmt 4700
20701
changes by RUS to the proposed
assemblies or drawings:
(1) RUS did not change any assembly
numbers as suggested in some of the
comments, but did add the following to
help borrowers understand implement
the new assembly numbers:
(a) A new paragraph on the title page
of the bulletin states that borrowers are
required to use the new specification
and drawings, however the borrowers
can choose to use the old assembly
numbers for 167 specified assemblies
that have duel numbers, and
(b) New Exhibit 5 at the end of the
bulletin that summarizes the new RUS
assembly numbering format and the
new numbers’ designated meanings.
This exhibit also tells where additional
information can be found.
(2) RUS found it necessary to
renumber the 167 re-used assemblies so
that all of the overhead distribution
assembly numbers would have a
consistent meaning and a standard
format. RUS believes that by allowing
the dual number system for a majority
of the new assemblies, it will aid the
borrowers in implementing the new
specifications.
(3) RUS recommends that borrowers
keep copies of old Bulletin 50–3 for
reference purposes and also keep all of
their present assemblies in their
engineering and accounting records
until (1) further guidance is issued by
RUS regarding the proper procedure to
retire discontinued assemblies and (2)
updates and publishes Bulletin 1767B–
2, ‘‘Work Order Procedure (Electric).’’
(4) Whereas some borrowers may
prefer not to turn any line angles on
tangent or small angle pole top
assemblies, NESC rules and RUS
requirements are not violated if angles
no greater than those referenced in the
design parameters on the drawings are
turned on these types of assemblies.
(5) Since the main purpose of the
vertical style of narrow profile pole top
assemblies, (e.g., A1.4N) is not to
‘‘straighten the line,’’ there is no need to
offset the neutral conductor in vertical
line with the primary conductor(s).
(6) Several drawings state that the
depicted assembly is to be used for
NESC Grade B construction. The sixth
paragraph in the ‘‘General Construction
Specification’’ explains some of the
needs for Grade B construction.
Additional details regarding the rules of
the NESC and their applications are
beyond the scope of this bulletin.
(7) Page 1 of Exhibit 1 presents the
formula, numerical constants and
variables used to calculate the permitted
line angles on pole top assemblies. In
part, the calculated angles are a function
of the number of pins installed on the
E:\FR\FM\21APR1.SGM
21APR1
20702
Federal Register / Vol. 70, No. 76 / Thursday, April 21, 2005 / Rules and Regulations
assembly and the RUS designated
(allowed) loading on pin and insulator
subassemblies. RUS agrees that
sometimes it is not readily apparent
why some types of pole top assemblies
can accommodate larger angles than
other types of assemblies. All of the
input data, calculations and resulting
permitted line angles have been
reviewed and found to be correct.
(8) The line angle on the drawing of
assembly A4.1 is purposely drawn at an
angle less than 90 degrees to show the
general range of angles that can be used
on this assembly.
(9) RUS believes that it is more
convenient for most borrowers to have
A4.1 and A4.2 as separate assemblies
instead of merging them into one
assembly.
(10) RUS agrees that guide drawing
A5.7NG does not depict a ‘‘squirrel
friendly’’ assembly. Nor is it raptor
friendly. If squirrels or raptors are
perceived to be a problem in a
borrower’s specific service area, then
RUS recommends using of other
assemblies (such as crossarm
assemblies) that are available in the new
bulletin.
(11) If needed for raptor protection,
borrowers may install offset neutral
brackets and may install the neutral on
either side of the pole of narrow profile
assemblies without further approval
from RUS if the modified assemblies
have a minimum of 4 feet of vertical
clearance between the neutral and the
primary conductor directly above it.
(12) These specifications are
minimum requirements, as a result,
borrowers may modify the anchor
assembly drawings to show the diameter
of the anchor helixes and may modify
the drawings of the pole top assemblies
to show the maximum permitted
transverse loading without approval
from RUS,
(13) Borrowers may make copies, regroup and re-arrange the assembly
drawings of this bulletin for their own
convenience and do not need from RUS,
(14) An extension bracket (item ‘‘fl’’)
is specified by RUS on assembly R1.1
and other similar equipment assemblies
to provide climbing space for line
workers. The extension bracket may be
omitted if the assembly is accessible for
work from bucket trucks designed for
such work.
(15) The RUS assembly drawings do
not show a pre-manufactured platform
for the installation of line regulators
because these types of platforms have
not been accepted for listing in RUS
Informational Publication 202–1 (‘‘List
of Materials’’).
(16) Assembly drawing Q4.1 shows
the use of crossarms because a cluster
VerDate jul<14>2003
16:25 Apr 20, 2005
Jkt 205001
bracket for installing primary metering
equipment has not been accepted for
listing in RUS Informational Publication
202–1.
(17) RUS believes that restricting
conductors to 2,000 pounds is
unnecessarily too restrictive.
(18) RUS no longer permits pin type
insulator to be installed in a horizontal
position, like in old assembly M5–4
because it has been reported that
horizontally installed pin insulators
sometimes fill with water and when the
water froze the insulator cracked.
(19) A new statement was added in
the ‘‘Conductor Installation
Specifications’’ stating that small
conductors can be installed on large
conductor assemblies (number suffix
‘‘L’’) but that their tensions cannot
exceed the permitted loads shown
design parameters on the assembly
drawings.
(20) Assemblies C5.22 and C5.32,
whose crossarm mounting position is
different that the other crossarm
assemblies and have limited
applications, are included in the new
bulletin upon request by some RUS
borrowers.
(21) New single-phase and two-phase
assemblies similar to proposed assembly
C5.71L for the application of large
conductors or NESC Grade B
construction were not added to the
bulletin because RUS perceives that
these additional assemblies would have
very limited use.
(22) The suggestion to add several
new large conductor assemblies was not
used. However, a statement was added
in the ‘‘General Construction
Specifications’’ that makes it clear that
borrowers may modify standard
crossarm assemblies to make them
suitable for large conductor construction
without approval by RUS.
(23) New double deadend assemblies
with conductor spacing the same as
proposed assemblies C5.22 and C5.32
was not used because these assemblies
are not RUS preferred construction and
are reduntant of other available
assemblies.
(24) RUS added new alternative
construction information and details in
the ‘‘Specifications for Guying
Assemblies’’ for situations where a
down guy might need to be installed
very close to the neutral conductor on
double deadend assemblies.
(25) RUS did not add a new double
deadend crossarm assembly with a
manufactured crossarm assembly (item
‘‘gj’’) in which the neutral deadends on
the crossarm because this new assembly
would have very limited use.
(26) RUS did not add a new assembly
with manufactured crossarm assemblies
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
and spacing the same as proposed
assembly D6.91 because this assembly
would be redundant of new assembly
D6.92, is relatively expensive, and thus
would have very limited use.
(27) RUS did not add a new, twophase, feedthrough guide drawing
because it is unnecessary. When
needed, jumper conductors and
connectors can be added to assembly
B6.21 similar to that shown on guide
drawing C6.52G.
(28) RUS did not add any new double
circuit assemblies with one circuit
installed above the other circuit because
RUS has standardized on the style of
double circuit construction as shown on
assembly drawings in the new bulletin.
The suggested alternative double circuit
design can be constructed using
assemblies C1.11 and B1.14 with slight
material modifications.
(29) No changes were made regarding
the guy attachments, bolts, washers, bolt
hole sizes, and the permitted loads of
proposed assemblies E1.1 and E1.1L.
The comments appear to be the result of
misunderstanding. The 6,600 pound
permitted load of assembly E1.1 is based
on the surface area of a 3-inch washer.
The 8,500 pound permitted load of
assembly E1.1L is based on 85 percent
of the RUS designated load (capacity) of
the guy attachment with a 4-inch
washer. RUS has (already) multiplied
the RUS designated strength of the guy
attachments by the 0.85 factor to
determine the permitted loads shown in
the design parameters on the drawings
of these assemblies. Both sized washers
have thirteen-sixteenths inch bolt holes
and can accommodate either a fiveeights inch or three-fourths inch bolt.
(30) The suggestion that an additional
flat washer or a three-fourth inch bolt be
used with washers with thirteensixteenths inch holes was not used
because RUS has never received reports
that five-eighths inch bolts have slipped
through the holes in standard washers.
(31) The reasons why old pole
protection assemblies M2–1 and M2–2
were discontinued by RUS was added to
the ‘‘Specification for Guying
Assemblies,’’
(32) RUS specifies the installation of
anti-split bolts on all non-tangent,
primary pole-top assemblies that have
double pole-top pins or double posttype insulator brackets. Borrowers may
install anti-split bolts on other pole top
assemblies at their own discretion;
however, the RUS permitted transverse
loading on these assemblies must not be
increased. Some borrowers have
reported to RUS that the installation on
anti-split bolts on all pole top
assemblies to be advantageous,
especially on cedar poles.
E:\FR\FM\21APR1.SGM

Federal Register / Vol. 70, No. 76 / Thursday, April 21, 2005 / Rules and Regulations
(33) Where appropriate, borrowers
may replace a cutout (item ‘‘af’’) and an
arrester (item ‘‘ae’’) with a combination
cutout/arrester (item ‘‘ax’’) without
additional review and approval by RUS.
The material for the assembly needs to
be changed accordingly.
(34) Additional information was
added to the ‘‘Specifications for Pole
Top Assemblies’’ stating that for NESC
Grade B construction, the permitted line
angles referenced on the pole top
assemblies may need to be reduced
based on the design engineer’s
calculations.
(35) Whereas the drawings for pole
top assemblies do not show the
permitted transverse load on the
assemblies, the subtitles of the tables in
Exhibit 1 referenced in the design
parameters on the drawings specify the
permitted transverse loads.
(36) The alleged errors regarding the
‘‘wild leg’’ and the high side grounding
on guide drawing G3.1G were checked
and determined to be correct as drawn.

Unfunded Mandates Reform Act
Title II of the Unfunded Mandate
Reform Act of 1995 (UMRA), Public
Law (Pub. L.) 104–4, establishes
requirements for Federal agencies to
assess the effects of their regulatory
actions on State, local, and tribal
governments and the private sector.
Under section 202 of the UMRA,
Federal agencies generally must prepare
a written statement, including costbenefit analysis, for proposed and final
rules with ‘‘Federal mandates’’ that may
result in expenditures to State, local, or
tribal governments, in the aggregate, or
to the private sector, or $100 million or
more in any 1 year. When such
statement is needed for a rule, section
205 of the UMRA generally requires a
Federal agency to identify and consider
a reasonable number of regulatory
alternatives and adopt the least costly,
more cost-effective, or least burdensome
alternative that achieves the objectives
of the rule.
This rule contains no Federal
mandates (under the regulatory
provisions of Title II of the UMA) for
State, local, and tribal governments or
the private sector. Therefore, this rule is
not subject to the requirements of
sections 202 and 205 of the UMRA.

loan guarantees are excluded from the scope of Executive Order 12372.
Executive Order 12988
This final rule has been reviewed under Executive Order 12988,
Civil Justice Reform. RUS has determined that this final 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 effect will be given
to this rule, and, in accordance with section 212(e) of the Department
of Agriculture Reorganization Act of 1994 (7 U.S.C. 6912 (e)),
administrative appeals procedures, if any are required, must be
exhausted before an action against the Department or its agencies may
be initiated.
Executive Order 13132, Federalism
The policies contained in this rule do not have any substantial
direct effect on 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. Nor does this
rule impose substantial direct compliance costs on State and local
governments. Therefore, consultation with states is not required.
Regulatory Flexibility Act Certification
It has been determined that the Regulatory Flexibility Act is not
applicable to this rule since the Rural Utilities Service is not
required by 5 U.S.C. 551 et seq. or any other provision of law to
publish a notice of final rule making with respect to the subject
matter of this rule.
Information Collection and Recordkeeping Requirements
This rule contains no additional information collection or

Unfunded Mandates
This final rule contains no Federal mandates (under the regulatory
provision of the Unfunded Mandates Reform Act of 1995 (2 U.S.C. Chapter
25)) for State, local, and tribal governments or the private sector.
Thus, this final rule is not subject to the requirements of sections
202 and 205 of the Unfunded Mandates Reform Act.
National Environmental Policy Act Certification
The Administrator of RUS has determined that this final rule will
not significantly affect the quality of the human environment as
defined by the National Environment 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 final rule is listed in the Catalog
of Federal Domestic Assistance Programs under No. 10.850, Rural
Electrification Loans and Loan Guarantees. This catalog is available on

(202) 512-1800.
Background
Pursuant to the Rural Electrification Act of 1936, as amended (7
U.S.C. 901 et seq.), the Rural Utilities Services (RUS) is amended
Title 7 CFR Chapter XVII, Part 1728, Electric Standards and
Specification for Materials and Construction, by revising RUS Bulletin
50-3 (D-804), ``Specification and Drawings for 12.5/7.2 kV Line
Construction.'' This revised bulletin will be renumbered as RUS
Bulletin 1728F-804 and will be re-titled as, ``Specification and
Drawings for 12.47/7.2 kV Line Construction.'' RUS maintains a system
of bulletins that contains construction standards and specifications
for materials and equipment which must be utilized when system
facilities are constructed by RUS electric and telecommunication
borrowers in accordance with the RUS loan contract. These standards and
specifications contain standard construction units, material, and
equipment units used in RUS electric and telecommunication borrowers'
systems.
RUS Bulletin 50-3 provides standard construction drawings and
specification of 12.5/7.2 kV overhead electric distribution lines. RUS
is proposing to change the bulletin number room RUS Bulletin 50-3
(Standard D 804) to RUS Bulletin 1728F-804 (D 804). The change in the
bulletin number and reformatting is necessary to conform to RUS new
publications and directives system. This rule will incorporate the
bulletin by reference in 7 CFR 1728.97.
Changes to RUS Bulletin 50-3 (D 804)
RUS has made the following changes and additions to RUS Bulletin
50-3 (D-804) renumbering it as Bulletin 1728F-804:
(1) The new bulletin contains a total of 382 assemblies. (An
assembly is a construction unit which incorporates the description and
quantity of material needed to construct the assembly and a dimensioned
schematic diagram showing how the material needs to be arranged or
assembled to meet RUS specifications.) Bulletin 50-3 currently contains
a total of 257 assemblies. In both bulletins, more than one similar
assembly is often depicted on one drawing.
(2) Of the 382 total assemblies in the new bulletin, 215 are new
assemblies and 95 of these 215 new assemblies are new ``narrow
profile'' assemblies. The drawing numbers and titles of the 215 new
assemblies and the 24 new guide drawings of the new bulletin are
tabulated in Exhibit 4 at the end of new Bulletin 1728F-804.
(3) Of the 382 total assemblies in the new bulletin, 167 are
standard assemblies of present Bulletin 50-3 that are being redrawn,
renumbered, and re-used in new Bulletin 1728f-804. Of these 167 re-used
assemblies, 94 are previous standard assemblies with no material
changes, 37 are previous standard assemblies with only a change in the
number or type of washers, and 36 are previous standard assemblies with
other slight material changes.
(4) The new bulletin also contains 32 new guide drawings and 8
renumbered, redrawn and thus re-used guide drawings from Bulletin 50-3.
Present Bulletin 50-3 contains a total of 32
[[Page 20700]]
guide drawings. (A guide drawing is a dimensioned schematic diagram
that shows details of how the material of one or more assemblies needs
to be arranged or assembled to meet RUS specifications but does not
list the material required for construction.)
(5) A listing the 167 re-used assemblies and 8 re-used guide
drawings, with both their old numbers and their new assigned numbers,
and the required assembly material changes, are tabulated in new
Exhibit 3 at the end of new Bulletin 1728F-804. Exhibit 3 also lists
the 90 assemblies and 24 guide drawings that are being discontinued
from Bulletin 50-3.
(6) Each of the 382 assemblies and 40 guide drawings in new
Bulletin 1728F-804 are being given a new number in accordance with the
assembly numbering format as updated by RUS in 1998. In the updated
numbering format, each letter and number in the assembly or drawing
number has a functional meaning.
(7) New Exhibit 5 at the end of the new bulletin summarizes the new
RUS assembly numbering format and briefly explains the meanings of each
letter or number in the new assembly and drawing numbers.
(8) The assembly drawings, the 19 drawing indexes and Exhibit 3 of
new Bulletin 1728F-804 show the new assigned assembly numbers and the
old numbers (in parentheses) of the 167 re-used assemblies and 8 re-
used guide drawings from present Bulletin 50-3. RUS allows the
borrowers to use either the old or the new assigned assembly number,
but only for the 167 re-used standard assemblies and 8 re-used guide
drawings. The borrower is being required to make the slight material
changes to 73 of the re-used assemblies and to construct the assemblies
as depicted.
(9) The new bulletin is being reformatted into 19 separate sections
or categories. Each section contains an index of drawings and also the
construction drawings of assemblies designed to perform a similar
function. Several sections contain construction specifications
pertaining to the assemblies in that section.
(10) New tables are being added in the new bulletin that define
maximum line angles (contained in Exhibit 1), permitted unbalanced
conductor tensions on crossarm assemblies (contained in Exhibit 2), and
soil classification data (contained in Section F).
(11) Exhibit, 1 being added at the end of the new bulletin,
documents the formula and data used to determine the maximum line
angles in the tables. Also, Exhibit 2, being added at the end of the
new bulletin, documents the formula and data used to determine
permitted unbalanced conductor tensions on crossarm assemblies.
(12) Each drawing is being given a new, uniform, shorter, and more
descriptive title. Each drawing also has a new, uniform title block
that contains, when applicable, the primary voltage and number of
phases of the depicted assemblies.
(13) ``Design parameters'' which define and usually limit maximum
line angles or mechanical loading (tension) is being added, when
applicable, to the drawings of the new bulletin.
RUS is discontinuing 90 assemblies and 24 guide drawings presently
contained in Bulletin 50-3 for one or more of the following reasons:
They contain material no longer accepted by RUS for use by
RUS borrowers,
Either the spacing or the strength of the assembly no
longer meets the minimum requirements of RUS or the rules of the
National Electrical Safety Code (NESC),
They contain technical errors such as a neutral conductor
support that is not coordinated with the primary conductor support,
They are redundant of other assemblies or for other
reasons may no longer be needed, or
They require so many modifications that it is prudent that
they be discontinued and subsequently replaced with new assemblies.
RUS also is modifying and adding to the construction specifications
in present Bulletin 50-3 incorporate the following significant changes
in Bulletin 1728F-804:
(1) Compliance and specific references to the 2002 Edition of the
NESC,
(2) Definitions of and provisions for the use of large and extra
large conductors,
(3) Permission to lower the neutral conductor under specific
circumstances,
(4) Requirement to use a washer under the shoulder of 7.2kV
crossarm pins,
(5) Requirement to use a 3-inch (minimum) square, curved, washer
abutting the pole for primaries, neutrals and guys that deadend on
poles,
(6) Requirement to multiply applied loads by the appropriate NESC
overload factors,
(7) Minimum insulated spacing (wood and fiberglass) between primary
conductors and guys,
(8) Choice of arrester location on transformer assemblies,
(9) Requirement that all secondary and service wires be covered
conductors,
(10) Permission to use stirrups provided certain given criteria are
met,
(11) Permission to insulate guy wires provided certain given
criteria are met,
(12) Permission to modify assembly drawings without further
approval from RUS within certain given parameters, and
(13) New rights-of-ways clearing specifications.
RUS Responses to Comments
On February 12, 2004, RUS published a proposed rule in the Federal
Register at 69 FR 6926 to incorporate by reference new Bulletin 1728F-
804 into its rules and regulations. A copy of the proposed bulletin was
made available to the general public on the RUS website and through the
U.S. mail. Members of the public were allowed 60 days to furnish RUS
with written comments regarding the proposed bulletin. Subsequently,
employees of the following rural electric cooperatives and other
business firms furnished RUS with written comments, suggestions and
questions regarding the proposed bulletin:
(1) Adams Electric Cooperative, Inc.
(2) Allgeier, Martin and Associates, Inc.
(3) Cookson Hills & East Central Electric Cooperative.
(4) Harrison Rural Electric Membership Cooperative.
(5) Hi-Line Engineering, LLC.
(6) Minnesota Valley Cooperative Light and Power.
(7) Morgan County Rural Electric Association.
(8) National Rural Electric Cooperative Association.
(9) Northern Neck Electric Cooperative.
In response to the comments and suggestions received, RUS has added
the following new assemblies and drawings to the bulletin:
Fifty-three assemblies with various combinations of secondary
brackets, swinging clevis', extension eyebolts and insulated extension
links to the A3, A5, B3, B5, C3 and C5 series of assemblies and also
added top views of assemblies to improve clarity, assemblies D1.5N and
D1.5NP to utilize offset neutral brackets on double circuit, narrow
profile assemblies, equipment assemblies R3.3 S2.3, Y3.1, and Y3.4,
guide drawing G1.2 (and consequently deleted some notes and the
schematic diagram on guide drawing G1.1), transformed the 9 ``tying
guides'' in Section L into 20 new assemblies, transformed guide
drawings E5.1G and
[[Page 20701]]
S1.1NG into assemblies, modified assemblies B4.2 and C4.2 to permit
line angles from 15 to 90 degrees, and transformed them into guide
drawings.
Also in response to the comments and suggestions received, RUS also
made the following changes and corrections:
(1) Corrected 85 errors and omissions pertaining to old assembly
numbers on the drawings, indexes, and exhibits,
(2) Changes the guy attachment location on 24 drawings to be
consistent with all of the other guyed assemblies,
(3) Changed the crossarm attachment location on 9 drawings so that
all crossarms are installed 18 inches from the top of the pole on all
assemblies to utilize standard pole drilling and to accommodate pole
top pins when needed,
(4) Added connectors (item ``p'') and jumper wires (item ``av'') to
the material lists on 18 drawings,
(5) Deleted notes referring to ``tying guides'' from 22 assemblies
because they were deemed not useful nor needed,
(6) Removed the note ``(When Req'd)'' referring to down guys from
12 drawings and added the same note to 5 drawings for the purpose of
accuracy and consistency,
(7) Added the ANSI class and size of spool insulator to the design
parameters of the 10 drawings that refer to the maximum line angles in
Tables VI and VII,
(8) Added or changed the distance from the face of the pole to the
nearest vertical jumper wired to 19 inches on 8 drawings to comply with
the rules of the NESC,
(9) Added an additional note in the design parameters utilizing
pre-assembled crossarms (item ``gj'') to multiply the manufacturer's
strength rating by the appropriate NESC strength factor to determine
the permitted loading on the assembly.
RUS also made the following changes to specific assembly drawings
in response to the comments and suggestions received:
Changed drawing numbers ``A1'', ``A2'' and ``N5'' to be
the same as the assembly numbers on the drawings to be consistent with
all of the other drawing numbers and removed ``Miscellaneous'' from the
drawing title,
Eliminating drawing ``A5'' and relocated its assemblies to
other drawings,
Corrected the line angle table reference errors in the
design parameters on drawings C1.3N, C2.3N and C2.3N,
Added a top view to assemblies A3.1, B3.1 and C3.1,
Increased the permitted line angle on assemblies A4.1,
B4.1, and C4.1 to the range of 90 to 175 degrees,
Deleted the note regarding down guys on the drawings of
assemblies A3.2, A3.3 and A4.1 because it was confusing. RUS added
information regarding the proper installation and location of guys to
the ``Specifications for Guying Assemblies,''
Corrected error in design parameters of drawing of
assembly C6.21 to refer to Note 2,
Changed the design parameters in the drawings of
assemblies C6.51 and A2.021 to reference Table B of Exhibit 2,
Deleted the un-referenced word ``ungrounded'' from guide
drawing G3.2G,
Added a note referencing NESC Table 232-2 to guide drawing
K4.1G,
Added crossarm mounting hardware to assembly S1.01 and a
note indicating that these switches may be installed on double deadend
crossarm assemblies,
Corrected the drafting errors pertaining to the conductors
on assembly Q1.1 and darkened the secondary conductors line on drawings
Q1.1, Q2.1 and Q3.1 to improve clarity,
Added a note to assembly drawings Q3.2 and Q3.3 requiring
customer-owned or maintained equipment be located a minimum for 5 feet
from the assembly,
Changed the materials on grounding assembly H1.1 to show
the installation of steel ground wire connecting to the anchor rod,
Added a note to drawing Q3.2 recommending PT's for
voltages over 240 volts,
Added a note to drawing S2.32 indicating that RUS accepted
pre-assembled switches may be used and to install them according to the
manufacturer's specifications,
Added notes to guide drawings D3.1G and D4.1G to adjust
material for only one neutral attachment subassembly and that the
minimum clearance between and guy and any primary conductor shall be 5
feet,
Modified assembly C5.22 so that the distance from the
neutral to the center phase conductor is 4 feet, 0 inches,
Changed the ground clearance to live parts on assembly
drawing Y1.1 to meet NESC requirements; the ground clearance to the
bottom of the regulator platform (which does not have braces) was found
to conform to the NESC and was not changed.
The following are RUS' responses to comments, suggestions and
questions that did not result in any additions or changes by RUS to the
proposed assemblies or drawings:
(1) RUS did not change any assembly numbers as suggested in some of
the comments, but did add the following to help borrowers understand
implement the new assembly numbers:
(a) A new paragraph on the title page of the bulletin states that
borrowers are required to use the new specification and drawings,
however the borrowers can choose to use the old assembly numbers for
167 specified assemblies that have duel numbers, and
(b) New Exhibit 5 at the end of the bulletin that summarizes the
new RUS assembly numbering format and the new numbers' designated
meanings. This exhibit also tells where additional information can be
found.
(2) RUS found it necessary to renumber the 167 re-used assemblies
so that all of the overhead distribution assembly numbers would have a
consistent meaning and a standard format. RUS believes that by allowing
the dual number system for a majority of the new assemblies, it will
aid the borrowers in implementing the new specifications.
(3) RUS recommends that borrowers keep copies of old Bulletin 50-3
for reference purposes and also keep all of their present assemblies in
their engineering and accounting records until (1) further guidance is
issued by RUS regarding the proper procedure to retire discontinued
assemblies and (2) updates and publishes Bulletin 1767B-2, ``Work Order
Procedure (Electric).''
(4) Whereas some borrowers may prefer not to turn any line angles
on tangent or small angle pole top assemblies, NESC rules and RUS
requirements are not violated if angles no greater than those
referenced in the design parameters on the drawings are turned on these
types of assemblies.
(5) Since the main purpose of the vertical style of narrow profile
pole top assemblies, (e.g., A1.4N) is not to ``straighten the line,''
there is no need to offset the neutral conductor in vertical line with
the primary conductor(s).
(6) Several drawings state that the depicted assembly is to be used
for NESC Grade B construction. The sixth paragraph in the ``General
Construction Specification'' explains some of the needs for Grade B
construction. Additional details regarding the rules of the NESC and
their applications are beyond the scope of this bulletin.
(7) Page 1 of Exhibit 1 presents the formula, numerical constants
and variables used to calculate the permitted line angles on pole top
assemblies. In part, the calculated angles are a function of the number
of pins installed on the
[[Page 20702]]
assembly and the RUS designated (allowed) loading on pin and insulator
subassemblies. RUS agrees that sometimes it is not readily apparent why
some types of pole top assemblies can accommodate larger angles than
other types of assemblies. All of the input data, calculations and
resulting permitted line angles have been reviewed and found to be
correct.
(8) The line angle on the drawing of assembly A4.1 is purposely
drawn at an angle less than 90 degrees to show the general range of
angles that can be used on this assembly.
(9) RUS believes that it is more convenient for most borrowers to
have A4.1 and A4.2 as separate assemblies instead of merging them into
one assembly.
(10) RUS agrees that guide drawing A5.7NG does not depict a
``squirrel friendly'' assembly. Nor is it raptor friendly. If squirrels
or raptors are perceived to be a problem in a borrower's specific
service area, then RUS recommends using of other assemblies (such as
crossarm assemblies) that are available in the new bulletin.
(11) If needed for raptor protection, borrowers may install offset
neutral brackets and may install the neutral on either side of the pole
of narrow profile assemblies without further approval from RUS if the
modified assemblies have a minimum of 4 feet of vertical clearance
between the neutral and the primary conductor directly above it.
(12) These specifications are minimum requirements, as a result,
borrowers may modify the anchor assembly drawings to show the diameter
of the anchor helixes and may modify the drawings of the pole top
assemblies to show the maximum permitted transverse loading without
approval from RUS,
(13) Borrowers may make copies, re-group and re-arrange the
assembly drawings of this bulletin for their own convenience and do not
need from RUS,
(14) An extension bracket (item ``fl'') is specified by RUS on
assembly R1.1 and other similar equipment assemblies to provide
climbing space for line workers. The extension bracket may be omitted
if the assembly is accessible for work from bucket trucks designed for
such work.
(15) The RUS assembly drawings do not show a pre-manufactured
platform for the installation of line regulators because these types of
platforms have not been accepted for listing in RUS Informational
Publication 202-1 (``List of Materials'').
(16) Assembly drawing Q4.1 shows the use of crossarms because a
cluster bracket for installing primary metering equipment has not been
accepted for listing in RUS Informational Publication 202-1.
(17) RUS believes that restricting conductors to 2,000 pounds is
unnecessarily too restrictive.
(18) RUS no longer permits pin type insulator to be installed in a
horizontal position, like in old assembly M5-4 because it has been
reported that horizontally installed pin insulators sometimes fill with
water and when the water froze the insulator cracked.
(19) A new statement was added in the ``Conductor Installation
Specifications'' stating that small conductors can be installed on
large conductor assemblies (number suffix ``L'') but that their
tensions cannot exceed the permitted loads shown design parameters on
the assembly drawings.
(20) Assemblies C5.22 and C5.32, whose crossarm mounting position
is different that the other crossarm assemblies and have limited
applications, are included in the new bulletin upon request by some RUS
borrowers.
(21) New single-phase and two-phase assemblies similar to proposed
assembly C5.71L for the application of large conductors or NESC Grade B
construction were not added to the bulletin because RUS perceives that
these additional assemblies would have very limited use.
(22) The suggestion to add several new large conductor assemblies
was not used. However, a statement was added in the ``General
Construction Specifications'' that makes it clear that borrowers may
modify standard crossarm assemblies to make them suitable for large
conductor construction without approval by RUS.
(23) New double deadend assemblies with conductor spacing the same
as proposed assemblies C5.22 and C5.32 was not used because these
assemblies are not RUS preferred construction and are reduntant of
other available assemblies.
(24) RUS added new alternative construction information and details
in the ``Specifications for Guying Assemblies'' for situations where a
down guy might need to be installed very close to the neutral conductor
on double deadend assemblies.
(25) RUS did not add a new double deadend crossarm assembly with a
manufactured crossarm assembly (item ``gj'') in which the neutral
deadends on the crossarm because this new assembly would have very
limited use.
(26) RUS did not add a new assembly with manufactured crossarm
assemblies and spacing the same as proposed assembly D6.91 because this
assembly would be redundant of new assembly D6.92, is relatively
expensive, and thus would have very limited use.
(27) RUS did not add a new, two-phase, feedthrough guide drawing
because it is unnecessary. When needed, jumper conductors and
connectors can be added to assembly B6.21 similar to that shown on
guide drawing C6.52G.
(28) RUS did not add any new double circuit assemblies with one
circuit installed above the other circuit because RUS has standardized
on the style of double circuit construction as shown on assembly
drawings in the new bulletin. The suggested alternative double circuit
design can be constructed using assemblies C1.11 and B1.14 with slight
material modifications.
(29) No changes were made regarding the guy attachments, bolts,
washers, bolt hole sizes, and the permitted loads of proposed
assemblies E1.1 and E1.1L. The comments appear to be the result of
misunderstanding. The 6,600 pound permitted load of assembly E1.1 is
based on the surface area of a 3-inch washer. The 8,500 pound permitted
load of assembly E1.1L is based on 85 percent of the RUS designated
load (capacity) of the guy attachment with a 4-inch washer. RUS has
(already) multiplied the RUS designated strength of the guy attachments
by the 0.85 factor to determine the permitted loads shown in the design
parameters on the drawings of these assemblies. Both sized washers have
thirteen-sixteenths inch bolt holes and can accommodate either a five-
eights inch or three-fourths inch bolt.
(30) The suggestion that an additional flat washer or a three-
fourth inch bolt be used with washers with thirteen-sixteenths inch
holes was not used because RUS has never received reports that five-
eighths inch bolts have slipped through the holes in standard washers.
(31) The reasons why old pole protection assemblies M2-1 and M2-2
were discontinued by RUS was added to the ``Specification for Guying
Assemblies,''
(32) RUS specifies the installation of anti-split bolts on all non-
tangent, primary pole-top assemblies that have double pole-top pins or
double post-type insulator brackets. Borrowers may install anti-split
bolts on other pole top assemblies at their own discretion; however,
the RUS permitted transverse loading on these assemblies must not be
increased. Some borrowers have reported to RUS that the installation on
anti-split bolts on all pole top assemblies to be advantageous,
especially on cedar poles.
[[Page 20703]]
(33) Where appropriate, borrowers may replace a cutout (item
``af'') and an arrester (item ``ae'') with a combination cutout/
arrester (item ``ax'') without additional review and approval by RUS.
The material for the assembly needs to be changed accordingly.
(34) Additional information was added to the ``Specifications for
Pole Top Assemblies'' stating that for NESC Grade B construction, the
permitted line angles referenced on the pole top assemblies may need to
be reduced based on the design engineer's calculations.
(35) Whereas the drawings for pole top assemblies do not show the
permitted transverse load on the assemblies, the subtitles of the
tables in Exhibit 1 referenced in the design parameters on the drawings
specify the permitted transverse loads.
(36) The alleged errors regarding the ``wild leg'' and the high
side grounding on guide drawing G3.1G were checked and determined to be
correct as drawn.
