SUPPLEMENTARY INFORMATION:
Executive Order 12866
This final rule is exempt from the Office of Management and Budget
(OMB) review for purposes of Executive Order 12866 and, therefore, has
not been reviewed by OMB.
Executive Order 12372
This final 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 entitled
``Department Programs and Activities Excluded from Executive Order
12372,'' (50 FR 47034) exempted the Rural Utilities Service loans and
loan guarantees from coverage under this order.
Executive Order 12988
This final rule has been reviewed under Executive Order 12988,
Civil Justice Reform. The Rural Utilities Service 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 final rule will be preempted. No
retroactive effect will be given to this final rule and in accordance
with section 212(e) of the Department of Agriculture Reorganization Act
of 1994 (7 U.S.C. 6912(e)) administrative appeal procedures, if any,
must be exhausted before an action against the Department or its
agencies may be initiated.
Executive Order 13132
This final rule will not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on distribution of power and responsibilities among the
various levels of government. Under Executive Order 13132, this final
rule does not have sufficient federalism implications to require
preparation of a Federalism Assessment.
Regulatory Flexibility Act Certification
The Rural Utilities Service has been determined that the Regulatory
Flexibility Act is not applicable to this rule since USDA Rural
Utilities Service is not required by 5 U.S.C. 551 et seq. or any other
provision of the law to publish a notice of proposed rulemaking with
request to the subject matter of this rule.
Information Collection and Recordkeeping Requirements
This final rule contains no new reporting or recordkeeping burdens
under OMB control number 0572-0076 that would require approval under
the Paperwork Reduction Act of 1995 (44 U.S.C. chapter 35, as amended).
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
a subscription basis from the Superintendent of Documents, U.S.
Government Printing Office, Washington, DC 20402-9325, telephone number
(202) 512-1800.
Unfunded Mandates
This final rule contains no Federal Mandates (under the regulatory
provision of title II 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 of 1995.
National Environmental Policy Act Certification
The Rural Utilities Service has determined that this final 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.

Background
General Discussion
The Rural Utilities Service maintains bulletins that contain
construction standards and specifications for materials and equipment.
These standards and specifications apply to systems constructed by
electric and telecommunications borrowers in accordance with the loan
contract, and contain standard construction units, materials, and
equipment units used on electric and telecommunications borrowers'
systems. The following bulletins establish standards for the
manufacture and inspection of wood utility poles, crossarms and pole
keys: Bulletin 1728F-700, ``RUS Specification for Wood Poles, Stubs and
Anchor Logs'' (incorporated by reference at Sec. 1728.97); 7 CFR
1728.201 ``Bulletin 1728H-701, Specification for Wood Crossarms (Solid
and laminate), Transmission Timbers, and Pole Keys;'' and 7 CFR
1728.202 ``Bulletin 1728H-
[[Page 28188]]
702, Specification for Quality Control and Inspection of Timber
Products.''
Changes to the Regulations
The Agency is affording the public an opportunity to comment on the
following changes to standards and specifications as applied to systems
constructed by electric and telecommunications borrowers:
1. Changes relevant to Bulletin 1728F-700 (incorporated by
reference at Sec. 1728.97), 7 CFR 1728.201, Bulletin 1728H-701, and 7
CFR 1728.202, Bulletin 1728H-702:
(a) Significantly limit the number of individual AWPA standards
contained in the reference section of the current RUS specifications.
RUS references several other national standards/specifications in
the wood products specifications. For the RUS standards to keep current
with each of these referenced documents, RUS would basically have to
change their wood product specifications to some degree every year. The
AWPA standards referenced in RUS specifications could best be kept
current by simply referencing two broad AWPA standards, AWPA Standard
U1, User Specification for Treated Wood and AWPA Standard T1,
Processing and Treatment Standard, rather than listing each individual
AWPA standard that is currently referenced in the RUS wood product
specifications. All the information contained in the long list of
individual AWPA standards now found in the RUS wood product
specifications is found somewhere in either of these two AWPA
standards.
(b) Add language to the specifications requiring that all third-
party agencies involved in the inspection of RUS products must, on an
annual basis, provide RUS Technical Standards Committee ``A'' with
proof that the agency does have: (1) The required insurance coverage,
and (2) the required, fully equipped laboratory capable of running each
of the referee methods of analysis.
While these two requirements themselves are not new, providing
proof of such to RUS on an annual basis is new. The reason for making
this change is that in recent years, there apparently have been several
instances where third-party agencies involved in RUS inspection did not
have the required insurance or the required lab facilities. Given that
RUS currently does not have the ability to provide an active overview
of these third-party agencies, this change simply provides RUS with a
method for checking the basic legitimacy of any company involved in the
inspection of RUS treated wood products. It also provides both RUS and
the cooperative borrower with some possible source of fiscal recovery
if problems with product service in line can be traced back to
performance issues involving the third-party agency being utilized.
(c) Addition of language that clearly defines the different
function of plant quality control versus the function of third-party
inspection.
This is a small but important change, in that over the past 30-40
years there has been a deliberate ongoing attempt by many former and
some current inspection agencies to blur the distinction between the
two functions to promote their inspection services. It is extremely
important that the cooperative utilities using these RUS specifications
understand exactly what the different function of plant quality control
and of third-party inspectors are, that these two are separate and
distinct functions, and that each has very specific requirements.
Clarifying the two will make it clear that the responsibility for
product quality does and always has rested with the producer,
eliminating the widespread fallacy that the responsibility for product
quality lies with the third-party inspector.
(2) Changes relevant only to Bulletin 1728F-700, (7 CFR 1728.97,
Incorporation by reference of electric standards and specifications,
(incorporation approved for 7 CFR 1728.98) and 7 CFR 1728.202, Bulletin
1728H-702:
Addition of language listing the referee methods of analysis for
each of the major types of preservatives used to treat RUS poles and
crossarms.
Over the last couple of decades, much of the wet chemistry that was
previously used to run retention analyses on treated wood poles and
crossarms has shifted to more modern and efficient methods, such as X-
ray fluorescence. This addition simply notes the current referee
methods for plant quality control labs and for the laboratories that
must be maintained by any third-party inspection agency involved in the
inspection of RUS treated wood products.
(3) Changes relevant only to Bulletin 1728F-700, ``Specification
for Wood Poles, Stubs and Anchor Logs (incorporated by reference at
Sec. 1728.97):''
(a) Eliminate northern white cedar as an acceptable pole species,
and eliminate any reference to it.
No manufacturer has produced a northern white cedar pole in over
four decades. Given the availability of many other far superior species
of trees for use as poles and crossarms, northern white cedar will not
be used for poles again. Removing it from the specification does not
affect a single producer.
(b) Change the restriction on the defect known as shelling to match
the shelling restrictions recently adopted by ANSI in their O5.1 pole
specification.
RUS currently restricts shelling to no more than one inch deep at
any point on a pole's surface. That used to match the ANSI restriction
for the same defect. Knowing this is a very dangerous defect that can
cause utilities a lot of problems, several years ago ANSI decided to
add an additional restriction to their shelling allowance. The current
ANSI O5.1 language on shelling restrictions reads ``Shelling on the
surface of the pole shall be limited to no more than one inch in depth
nor exceed \1/3\ of the pole's circumference at the point of
shelling.'' Manufacturers are already operating under the current ANSI
shelling restriction, so RUS adopting it in their specification will
have no impact on the industry while providing a better overall product
for cooperatives.
(c) Modify the language in the RUS specification dealing with rate
of growth requirements for poles.
RUS has always had a rate of growth requirement (ring count
requirement) to ensure that the trees used for poles have adequate
strength characteristics. Given that ring count is a critical component
in determining the strength of an individual pole, the proposed
language modification to denote a ``referee'' method for determining
ring count is a very important improvement to the current RUS
specifications. This change will have no impact on the way ring count
is currently determined, just provides clarification about how any
difference of opinion over ring count in an individual pole is to be
determined if there is a difference of opinion on the issue between two
parties.
(d) Modify the language that ``no pole treated with an oil-borne
preservative (penta and copper naphthenate) or with creosote can be
shipped to a RUS borrower more than two years after its original
treatment date'' to also include poles treated with water-borne
preservatives such as CCA or ACZA.
The language modification is to make this two-year restriction
applicable to all RUS poles, regardless of type of treatment. This
change will bring all of the major preservatives under the same
restriction. Given that both oil-borne preservatives and creosote do
migrate over time to the low side of stored poles, it prevented
potential problems with pole service life due to possibly significantly
lower preservative content on the top side of poles held in a
[[Page 28189]]
producer's treated stock for an extended period. This two year ``drop-
dead'' requirement also encouraged manufacturers to rotate their stock
on a reasonably short basis, meaning they could provide their
cooperative customers with the ``new'' fresher poles that utilities
expected when they made pole purchases.
(e) Addition of a specific listing in Table 10 in Appendix A of
Bulletin 1728F-700, the pole specification, that allows for the
treatment Alaska Yellow Cedar with copper naphthenate.
Normally when cedar poles are produced, the vast bulk of the cedar
itself is one species, western red cedar. However, a small amount of
that volume might also be Alaska yellow cedar. The two species are
quite similar in the way they look and treat. Apparently at least one
large producer in the western region has developed a significant supply
of Alaska yellow cedar that they wanted to produce and treat with
copper naphthenate on a full charge basis. The species is a very good
pole species, but there was no allowance for treating full charges
composed of only Alaska yellow cedar in RUS Table 10. This change will
add that allowance to Table 10. Overall, it will have a negligible
impact on the industry because of the relatively scarcity of pure
stands of Alaska yellow cedar.
(4) The following changes in the rule making are relevant only to 7
CFR 1728.201, RUS Bulletin 1728H-701, ``Specification for Wood
Crossarms (Solid and Laminated), Transmission Timbers and Pole Keys.''
(a) Eliminate the allowance for producing thermal non-pressure
treated crossarms.
The last thermal dip treating facility for crossarms was closed
over 35 years ago. All of the crossarms produced today, whether
Douglas-fir or southern pine, are pressure treated. Pressure treatment
provides a much more uniform treatment and a far better product.
(b) Slight modification of the language contained in the one-year
warranty for RUS crossarms to address the fact that no crossarms are
sold directly from a crossarm producer to a cooperative, but rather are
sold only through distributorships.
The current language in the crossarm warranty states ``If any
crossarm is determined to be defective within 1 year after delivery to
the borrower, it shall be replaced as promptly as possible by the
producer.'' The modification simply replaces the word ``producer'' with
the word ``supplier''. The term ``supplier'' is already properly
defined elsewhere in the specification.
(5) The following changes in the rule making are relevant only to 7
CFR 1728.202, Bulletin 1728H-702, ``Specification for Quality Control
and Inspection of Timber Products.''
(a) Remove the Insured Warranty Program (IW) as a purchase plan for
poles.
The IW program was started back in the late 60's as another option
for cooperative borrowers to use for inspection of RUS treated poles
they were purchasing. The IW program ended in the mid 70's. Given that
insurance premiums on a natural product like a wood pole or crossarm
are very expensive (if an agency will even provide the coverage at
all), and that there are other effective purchase plans available to
cooperatives, and that IW hasn't been used in over 40 years, it needs
to be removed from the specifications.
(b) Relocation of appendix A (formerly located in Sec. 1728.202).
Appendix A, Inspector's Qualifications, was formerly located in
Sec. 1728.202. It is relocated to new Sec. 1728.203, Inspector's
qualifications, to comply with the codification requirements in 1 CFR
chapter I.

Sec. 1728.201 Bulletin 1728H-701, Specification for Wood Crossarms
(Solid and Laminated), Transmission Timbers and Pole Keys.
(a) Scope. (1) The specification in this section describes the
minimum acceptable quality of wood transmission and distribution
crossarms (hereinafter called arms) purchased by or for RUS borrowers.
Where there is conflict between the specification in this section and
any other specification referred to in this section, the specification
in this section shall govern.
(2) The requirements of the specification in this section implement
contractual provisions between RUS and borrowers receiving financial
assistance from RUS. The contractual agreement between RUS and a RUS
borrower requires the borrower to construct its system in accordance
with RUS accepted plans and specifications. Each RUS electric and
telecommunications borrower shall purchase only arms produced in
accordance with the specification in this section. Each RUS electric
and telecommunications borrower shall require a written confirmation
from their selected contractor that all material utilized shall be
produced in accordance with the specifications in this section.
(b) General stipulations. (1) Conformance of arms to RUS
specifications is the responsibility of the producer. A member of the
producer's staff shall be designated as quality control supervisor and
charged with the responsibility for the exercise of proper quality
control procedures throughout the production process. The primary
responsibility of third-party inspection agencies is to verify that
producers involved in the manufacture of RUS treated wood products have
functional in-house quality control systems in place that result in the
shipment of materials meeting applicable RUS specification requirements
to borrowers.
(2) Treated wood products intended for RUS borrowers shall not be
inspected when in the opinion of the inspector, unsafe conditions are
present.
(3) Various requirements relating to quality control and inspection
that are contained in Sec. 1728.202 and ANSI O5.2 and ANSI O5.3 (both
incorporated by reference in Sec. 1728.97) shall be followed exactly
and shall not be interpreted or subject to judgment by the producer's
quality control personnel or by the third party inspector.
(4) The requirements of AWPA M3 (incorporated by reference in Sec.
1728.97) pertaining to record keeping, pre-treatment storage,
analytical laboratories, plant gauges and other plant facilities, shall
be followed.
(5) The producer shall maintain its own properly staffed and
equipped analytical laboratory or contract with an independent testing
laboratory at or near the treating plant to provide the required
analytical service. On a case-by-case basis, with written permission
from RUS, a producer with more than one treatment facility may be
allowed to use a central laboratory.
(6) Arms can be purchased under either of two purchase plans; a RUS
approved Quality Assurance Plan or an Independent Inspection Plan. The
method of inspection described in this section shall be used no matter
which plan timber products are purchased under.
(7) All third-party inspectors involved in the inspection of RUS
products shall maintain their impartiality when providing their
inspection service. This requires that these individuals and their
[[Page 28192]]
employers, as well as producers and suppliers involved in providing RUS
borrowers with treated wood products, maintain a professional
separation during the performance of their respective functions to
eliminate any possible conflict of interest.
(8) With the exception of financial agreements for inspection
services, inspection agencies shall neither accept nor provide
gratuities or free services to suppliers.
(9) Inspection agencies shall not offer product warranties on
inspected material.
(10) Arms shall be warranted to conform to this specification. Arms
shall meet or exceed their minimum allowable dimensions for at least
one year from time of delivery to the borrower. If any arm is
determined to be defective or does not conform to this specification
within 1 year from the date of delivery to the borrower, it shall be
replaced as promptly as possible by the supplier. In the event of
failure to do so, the purchaser may make such replacement and the cost
of the arm, at destination, shall be recovered from the supplier.
(c) Definitions. The following definitions apply to this section:

not exceed \1/2\ the equivalent displacement of a round knot permitted
at that location, provided that the depth of the knot on the worst face
shall not exceed the maximum round knot allowed at that location.
(v) Loose knots shall be prohibited in deadend arms. Loose knots
and knot holes shall be permitted only if they allow water to drain
when the arm is installed in its normal position. In the center
section, upper half, loose knots shall not be greater than \1/2\ the
dimensions of round knots. Elsewhere, loose knots shall not be greater
than the round knot dimension.
(vi) All knots except those ``spike'' knots intersecting a corner
shall be measured on the least diameter of the knot.
(vii) A knot shall be considered to occupy a specific zone or
section if the center of the knot (i.e., pith of knot) is within the
zone or on the zone's boundary.
(viii) If a round or oval knot appears on two faces and is in two
zones, each face shall be judged independently. When this does not
occur, average the least dimension showing on both faces. Knots which
occur on only one face of a free of heart center (FOHC) arm shall be
permitted to be 25 percent larger than the stated size.
(ix) Two or more knots opposite each other on any face shall be
limited by a sum not to exceed the size of a maximum single knot
permitted for the location. On all four faces, all knots shall be well
spaced.
(x) No knot over \5/8\ inch in diameter may intersect pin holes in
the center section. One-inch diameter knots may intersect insulator pin
holes elsewhere.

the appropriate inspection program.
(6) All third-party inspectors involved in the inspection of RUS
products shall maintain their impartiality when providing their
inspection service. This requires that these individuals and their
employers, as well as producers and suppliers involved in providing RUS
borrowers with treated wood products, maintain the greatest degree of
professional separation during the performance of their respective
functions to eliminate any possible conflict of interest.
(7) With the exception of financial agreements for inspection
services, inspection agencies shall not accept nor provide gratuities
or free services to suppliers.
(8) Inspection agencies shall not offer product warranties on
inspected material.
(9) Inspection agencies shall have and maintain liability insurance
in the amount of $500,000 and a surety bond or miscellaneous Errors and
Omission insurance for consequential damages for not less than
$250,000. Evidence of compliance to the requirement in this paragraph
(b)(9) shall be forwarded to the RUS annually. The evidence shall be in
the form of a certificate of insurance or a Bond signed by a
representative of the insurance or Surety Bonding company and include a
provision that no change in, or cancellation of, will be made without
the prior written notice to Chairman, Technical Standards Committee
``A'' (Electric).
(10) Inspection agencies shall maintain their own properly equipped
laboratory that, at a minimum, is able to run the referee methods
listed in table 1 to this paragraph (b)(10) for retention analysis for
all preservatives being inspected. This laboratory shall be independent
from any treating plant laboratory. Inspection Agencies may use one
central laboratory. All XRF units maintained by third party inspection
agencies as part of their RUS required laboratories shall be calibrated
at least quarterly by said agency utilizing the referee method for each
preservative treatment being analyzed or via comparison with a set of
graduated treated wood standards. Each agency shall keep an up-to-date
written record of these quarterly calibration results. AWPA A83
(incorporated by reference at Sec. 1728.97) shall be followed for
Pentachlorophenol testing, AWPA A6 (incorporated by reference at Sec.
1728.97) shall be followed for Creosote testing and AWPA A9
(incorporated by reference at Sec. 1728.97) shall be followed for XRF
be followed, as illustrated in the following table:
Table 1 to Paragraph (b)(10)
------------------------------------------------------------------------
Preservative Referee method
------------------------------------------------------------------------
Pentachlorophenol..................... Lime Ignition, Copper Pyridine.
Creosote.............................. Toluene Extraction.
Waterborne............................ X-ray fluorescence (XRF).
Copper Naphthenate.................... X-ray fluorescence (XRF).
------------------------------------------------------------------------
(11) If used for analysis, plant XRF units shall be accurate and
generate reproducible results per AWPA A9. At least once monthly, their
accuracy and precision shall be checked by the third-party inspector.
This verification shall consist of the inspector taking a retention
sample previously analyzed by the plant quality control supervisor on-
site and rerunning it in the inspection agency's own laboratory using
said agency's XRF unit or the referee method for a specific
preservative. If the inspection agency's analytical result is within
+5% of the plant's retention result on that sample, the plant XRF unit
needs no further calibration.
(12) Individual inspectors in the employ of inspection agencies
shall be properly trained and experienced. See Sec. 1728.203, for
details of an inspector's minimum qualifications. Upon request,
inspection agencies must provide RUS with detailed written
documentation verifying that each of their employees inspecting RUS
materials has the minimum experience and training described in Sec.
1728.203. Failure of an individual inspector to follow proper
procedures or failure of an inspection agency to properly train and
supervise their inspectors or follow applicable RUS specifications
constitutes grounds for RUS debarment of said inspector and said
inspection agency from future inspection of RUS financed material.
(c) Quality control and inspection procedures. It is the
responsibility of the plant quality control supervisor to perform the
following procedures to ensure that a particular lot of material
conforms to the requirements of the applicable Agency specification
prior to treatment. After the plant quality control supervisor has
performed these procedures, a particular lot of material shall be
released to the inspector for verification of conformance.
(1) For poles, inspection prior to treatment shall include:
(i) Ample space and assistance shall be provided by the treating
plant for handling and turning poles. Regardless of the purchase plan
poles are being purchased under, all poles in a lot shall
[[Page 28199]]
be inspected by the plant quality control supervisor prior to offering
the lot for verification by a third party.
(ii) When limited by the purchaser in a written purchase order,
moisture content shall be measured with a calibrated electronic
moisture meter. Calibration of the moisture meter shall include not
only the zero settings for the X and Y readings, but also two
resistance standards for 12 and 22 percent moisture content. Material
failing to conform for moisture content may be retested upon request
after recalibration of the moisture meter.
(iii) Dimensions, length, and circumference shall be measured by a
standard steel tape to determine that they meet specification
requirements and that they agree with the details for class and length
found in the face brand/tag and butt of each pole. If it is obvious by
visual comparison with a measured pole that the brand information
regarding class and length is correct, individual poles need not be
measured. Pole circumference dimensions measured prior to treatment
shall govern acceptance. Reduction in dimension due to treatment and
shipping shall be no more than 2 percent below the minimum for the pole
class.
(iv) Poles in a lot shall be of the same seasoning condition and
all shall be inspected for decay. If the plant quality control
supervisor suspects that decay is present in a pole, a slice from both
ends shall be cut for closer examination. If 3 percent or more of the
poles in the lot inspected by the plant quality control supervisor show
evidence of decay, the entire lot shall be unconditionally withdrawn
without further sorting.
(v) Under the Independent Inspection Plan, all poles shall be
examined by the third-party Inspector for verification of conformance.
Under a RUS approved Quality Assurance Plan, the number of poles
inspected for verification of conformance may vary according to the
terms of the approved plan.
(vi) Whenever it becomes evident during third party inspection of
any lot of poles offered by the producer that non-conforming pieces
exceed 3 percent for any one defect or 5 percent for all defects, the
inspector shall withhold further inspection and reject the balance of
the lot. After the producer has acted to eliminate all defective
pieces, the rejected balance may be inspected as a new lot. Sorting,
however, shall not be permitted when a lot has been rejected for decay.
(vii) Re-examination for mechanical damage or deterioration and for
original acceptance shall be conducted on timber products not treated
within 10 days after the original third-party inspection.
(2) For crossarms, inspection prior to treatment shall include:
(i) Regardless of the purchase plan arms are being purchased under,
all arms in a lot shall be inspected by the plant quality control
supervisor prior to offering the lot for verification by a third party.
After the plant quality control supervisor has performed the procedures
in paragraphs (c)(2)(ii) through (vii) of this section, a particular
lot of arms shall be released to the inspector for verification of
conformance.
(ii) Moisture content of the arms in the lot shall be checked with
a calibrated moisture meter.
(iii) Surface inspection of both ends and the side surfaces of each
arms. Particular attention shall be paid to visible defects such as
compression wood, red heart, honeycomb and other forms of decay,
shakes, splits, through checks, low density, wane, undersize, and pitch
pockets.
(iv) Inspection of bolt and insulator pin holes for proper
location, dimension and excessive splintering.
(v) Inspection of brands for proper location, required content and
legibility.
(vi) Under the Independent Inspection, both ends of all crossarms
and a random representative sample of the lengthwise side faces of all
crossarms shall be inspected. The sample size shall equal 20 percent of
the lot size or 200 arms, whichever is smaller. Under a RUS approved
Quality Assurance Plan, the number of crossarms inspected for
verification of conformance may vary according to the terms of the
approved plan.
(vii) Whenever it becomes evident during third party inspection of
any lot of arms offered by the producer that non-conforming pieces
exceed 2 percent of the sample size, the entire lot shall be rejected.
After the producer has acted to eliminate all defective pieces, the
rejected balance may be inspected as a new lot.
(d) Preservatives. Creosote, waterborne preservatives,
pentachlorophenol and copper naphthenate shall conform to current AWPA
U1 (incorporated by reference in Sec. 1728.97).
(e) Results of treatment--Poles. (1) Following treatment, poles
shall be sampled for preservative retention and penetration utilizing a
calibrated increment borer 0.2 inches +0.02 inches in diameter in
accordance with procedures listed in AWPA M2 (incorporated by reference
in Sec. 1728.97).
(2) Inspectors may take their own retention samples and analyze
them concurrently with those taken by the quality control supervisor,
but each shall work independently. The results of the plant's analysis
shall be presented before verification and acceptance of the charge by
the third-party inspector.
(3) Unless otherwise specified, borings shall be taken from the
section of the pole extending from 1 foot below the face brand/tag to 1
foot above the face brand/tag. For pressure treated Western Red Cedar,
Alaska Yellow Cedar and all butt treated poles, borings shall be taken
from the section of the pole approximately 1 foot below groundline.
(4) For all species, core samples shall be taken from 20 poles in
charges of 20 or more poles. If a charge consists of less than 20
poles, each pole shall be bored and then individual poles shall be
bored a second time to obtain a minimum of 20 core samples. Any
additional borings required to obtain the required 20 core samples
shall be taken in a manner that represents the lot of material with
respect to variations in size, seasoning condition, or other features
that may affect the results of treatment.
(5) Retention and penetration samples shall consist of borings
representative of pole volumes for each class and length in the charge,
as illustrated in the following table:
Table 2 to Paragraph (e)(5)
----------------------------------------------------------------------------------------------------------------
% of total Number of
Number of poles Class/length Vol. in ft\3\ vol. borings \1\

\1\ Retention and penetration requirements for each different species and preservative are listed in Table 10 of
Appendix A, RUS Bulletin 1728F-700, Specification for Wood Poles, Stubs and Anchor Logs (incorporated by
reference at Sec. 1728.97).
(6) Preservative retention analyses shall be performed per the
standard AWPA U1, (incorporated by reference at Sec. 1728.97).
(7) Penetration compliance of both poles and crossarms shall be
determined in accordance with the standard AWPA A15 (incorporated by
reference at Sec. 1728.97). Chrome Azurol S and Penta-Check shall be
used to determine the penetration of copper containing preservatives
and penta, respectively.
(8) All bored holes created by penetration and retention sampling
shall be promptly filled with tight fitting treated plugs.
(9) Penetration sampling of poles shall be carried out as follows:
(i) Group A poles (Those poles with a circumference of 37.5 inches
or less at 6 feet from butt.):
(A) Bore 20 poles or 20 percent of the poles in the charge,
whichever is greater. Accept all poles in the charge for penetration if
every boring in the sample conforms. If any sample fails penetration,
bore all poles in the charge.
(B) If more than 15% of the poles in the charge are found to be
nonconforming, the entire charge shall be retreated. If 15% or less are
found to be nonconforming, remove and retreat only those that are
nonconforming.
(ii) Group B poles (Those poles with a circumference greater than
37.5 inches at 6 feet from the butt.):
(A) For Group B poles 45 feet and under, bore each pole in the
charge. If more than 15% of these poles are found to be nonconforming,
the entire charge shall be retreated. If 15% or less are found to be
nonconforming, remove and retreat only those that are nonconforming.
(B) For Group B poles 50 feet and over, bore each pole twice at 90
degrees apart and accept only those poles conforming to penetration in
both borings.
(iii) Nonconforming poles may be treated only twice. The letter
``R'' shall be added to the original charge number in the butts of all
poles that are retreated. Poles failing to meet treatment requirements
after two retreatments shall be permanently rejected and all brand and
butt information removed.
(f) Results of treatment--Crossarms. Retention and penetration
samples shall be taken from not less than 20 crossarms in each charge.
The sampling method and retention and penetration requirements for both
Douglas-fir and Southern Yellow Pine crossarms are listed in Sec.
1728.201.
(g) Product acceptance. (1) Third party inspectors shall verify
their acceptance of untreated poles that have been offered by the
producer as conforming by marking each accepted piece in the tip with a
clear, legible hammer stamp. Following treatment, inspectors shall
verify their acceptance of treated poles that have been offered by the
producer as conforming by marking each accepted piece in the butt with
a clear, legible hammer stamp. Inspection marks are not to be placed in
the butt surfaces of any poles prior to treatment and proper retention
analysis and penetration testing being completed. The inspector shall
personally mark each piece for acceptance and shall not delegate this
responsibility to any other individual.
(2) Each inspector or inspection agency shall retain for a period
of at least one year a copy or transcript of each pre-treatment
inspection report and a copy of analytical worksheets covering
retention and penetration test results for each treated charge of
material inspected. On request, a copy or transcript of these reports
shall be furnished to the Chairman, Technical Standards Committee
``A'', Rural Utilities Service, Washington, DC 20250-1569.
(i) On each inspection report the third-party inspector and the
plant quality control supervisor shall certify in writing that the
material listed on the report has been properly inspected both before
and after treatment and that the preservative used met the requirements
of this section. Inspection reports shall also include the following
information:
(A) Conditioning details of the material prior to treatment.
(B) Total number of pieces offered by the producer.
(C) Number of pieces rejected by the inspector, cause for
rejection.
(D) Copy of preservative analysis (usually supplied by the
preservative supplier).
(E) Treating sheet containing details of treatment for each charge.
(F) Separate worksheets for retention analyses done by the plant
quality control supervisor and by the inspector.
