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 § 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-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 § 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 § 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 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 § 1728.202).
Appendix A, Inspector's Qualifications, was formerly located in § 1728.202. It is relocated to new § 1728.203, Inspector's qualifications, to comply with the codification requirements in 1 CFR chapter I.

(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 § 1728.202 and ANSI O5.2 and ANSI O5.3 (both incorporated by reference in § 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 § 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 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.

5. Revise § 1728.202 to read as follows:
(a) Scope. (1) The specification in this section describes the responsibilities and procedures pertaining to the quality control by producers and pertaining to inspection of timber products produced in accordance with the following RUS specifications in § 1728.201, and poles, covered in Bulletin 1728F-700 (incorporated by reference in § 1728.97) and in § 1755.97 of this chapter.
(2) Where there is conflict between the specification in this section and any other specification referred in this section, the specification in this section shall govern.
(3) The specification in this section also describes and designates responsibilities of RUS borrowers in regard to their purchases under the specifications referenced in paragraph (a)(1) of this section.
(b) General stipulations. (1) Conformance of poles and crossarms 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) The requirements of AWPA M3 (incorporated by reference at § 1728.97), pertaining to recordkeeping, pretreatment storage, analytical laboratories, plant gauges, and other plant facilities, shall be followed.
(3) Treated wood products intended for RUS borrowers shall not be inspected when in the opinion of the inspector, unsafe conditions are present.
(4) Poles and crossarms 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.
(5) Under the Independent Inspection Plan, the borrower should designate in the purchase order which inspection agency it has selected. Unless the borrower contracts for inspection as a separate transaction, the treating company shall obtain the services of the borrower's designated inspection agency. For reserve treated stock held in inventory by the producer, the producer shall obtain the services of 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 § 1728.97) shall be followed for Pentachlorophenol testing, AWPA A6 (incorporated by reference at § 1728.97) shall be followed for Creosote testing and AWPA A9 (incorporated by reference at § 1728.97) shall be followed for XRF be followed, as illustrated in the following table:
| 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 § 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 § 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 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 § 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 § 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:
| Number of poles | Class/length | Vol. in ft3 | % of total vol. | Number of borings 1 |
|---|---|---|---|---|
| 20 | 5/40 | 550 | 22 | 4 |
| 30 | 4/40 | 840 | 34 | 7 |
| 20 | 4/45 | 510 | 20 | 4 |
| 20 | 3/45 | 600 | 24 | 5 |
| Total | 2,500 | |||
| 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 § 1728.97). | ||||
(6) Preservative retention analyses shall be performed per the standard AWPA U1, (incorporated by reference at § 1728.97).
(7) Penetration compliance of both poles and crossarms shall be determined in accordance with the standard AWPA A15 (incorporated by reference at § 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 § 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.
(G) Penetration result on each individual core boring taken from poles in the charge.
(ii) [Reserved]
(h) Laminated materials. (1) All lumber used to fabricate laminated materials shall be inspected and its grade verified by a qualified lumber grader, then marked appropriately.
(2) Laminated materials shall comply with manufacturing requirements specified in ANSI O5.2 (incorporated by reference at § 1728.97). Melamine urea adhesives shall not be used. Plant quality control procedures and any third-party inspection shall be conducted in accordance with AITC 200 (incorporated by reference at § 1728.97), and § 1728.201 (Bulletin 1728H-701).
(3) Following treatment, laminated material shall be checked for proper preservative retention and penetration, and for any evidence of delamination. All conforming laminated materials shall be clearly marked with either an American Institute of Timber Construction (AITC) or American Plywood Association (APA) quality stamp.
(i) Safety provisions. Poles intended for agency borrowers shall not be inspected when, in the opinion of the inspector, unsafe conditions are present.
6. Add § 1728.203 to read as follows:
