SUPPLEMENTARY INFORMATION:

Executive Order 12866

This final rule is exempted 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 information collection and recordkeeping requirements contained in this final rule are cleared under OMB control number 0572-0076 pursuant to the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35, as amended).

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.

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. See the final rule related notice titled “Department Programs and Activities Excluded from Executive Order 12372” (50 FR 47034), advising that the Rural Utilities Service loans and loan guarantees are excluded from the scope of Executive Order 12372.

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.

General Discussion

A proposed rule entitled “Standards and Specifications for Timber Products Acceptable for Use by Rural Development Utilities Programs' Start Printed Page 36962Electric and Telecommunications Borrowers” was published in the Federal Register on September 29, 2008 at 73 FR 56513, and the public was invited to submit comments on or before November 28, 2008. Comments were received and are addressed in the Summary of Comment section of this rule.

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. Bulletins 1728F-700, “Specification for Wood Poles, Stubs and Anchor Logs”; 1728H-701, “Specification for Wood Crossarms (Solid and Laminated), Transmission Timbers and Pole Keys”; and 1728H-702, “Specification for Quality Control and Inspection of Timber Products”, establish standards for the manufacture and inspection of wood utility poles, crossarms and poles keys. The summary of the major changes to these three bulletins are as follows:

1. All references cited in these bulletins are updated to the latest edition.

2. The definition “pole broker” was added to the list of definitions to include as many organizations as possible to provide borrowers a source from which they might purchase wood products.

3. Allow borrowers six months to notify treating plants about poles not meeting the required preservative retention.

4. In accordance with RUS policy on insurance requirements for contractors working for borrowers, the specification was revised to require manufacturers and inspection agencies to maintain certain limits of liability and errors and omission insurance.

5. All poles are required to be sterilized during the conditioning or treating cycle. This sterilization should further reduce the number of poles with pre-treatment decay.

6. Required to brand independent inspection agency's identification on the face of the pole.

7. RUS revised the qualifications for inspectors and quality control personnel and will return to the qualifications from the 1987 edition of the specifications.

8. Provisions are added to further clarify that wood products, producers and inspection agencies maintain the greatest degree of separation and eliminate any appearance of conflict of interest.

Summary of Comments

The Agency received comments and recommendations in response to the proposed rule from the following organizations: North American Wood Pole Council (NAWPC), McFarland Cascade, Cox Industrial Group, Wood Quality Control (WQC), Cox Industrial Group, Lee Inspection and Consulting Services, A.W. Williams Inspection Co. (AWW), Texas Electric Cooperatives (TEC), Timber Products Inspection and Dis-Tran Wood Products. No comments from any other sources were received. These comments and recommendations and the Agency's responses are summarized as follows:

Comment: Lee Inspection, NAWPC, TEC, and AWW questioned the need for liability insurance and errors and emission insurance and the amount of coverage.

Agency Response: RUS has required outside contractors doing work for borrowers to have high levels of liability insurance for many years. The insurance requirement was added to stay in line with present agency practices. The proposed insurance was reviewed and the errors and omission insurance requirement was eliminated for pole and crossarm producers. Since inspection agencies are performing a service, their liability and errors and omissions insurance requirement remains.

Comment: NAWPC and Timber Products Inspection questioned the need to treat kiln dried poles within 30 days after drying.

Agency Response: Paragraph 4.2.1 of Bulletin 1728F-700 dated September 1993 requires that “kiln dried poles shall be treated within 1 month from the time they are removed from the kiln.” This has been an RUS requirement for nearly twenty years and RUS believes that this requirement is needed.

Comment: NAWPC and Timber Products Inspection questioned why there is an inconsistency in paragraph 8.1 of Bulletin 1728F-700 concerning sterilization of Douglas fir poles.

Agency Response: The sterilization time for Douglas-fir is revised to be in line with other species.

Comment: McFarland, NAWPC and Timber Products Inspection suggested the inclusion of the modified full cell process to help control overtreatment.

Agency Response: The modified full cell process was added as suggested.

Comment: Timber Products Inspection pointed out that the maximum temperature for treatment in Western Red Cedar in the table in paragraph 8.2 of Bulletin 1728F-700 is not in agreement with American Wood Protection Association Standards.

Agency Response: Bulletin 1728F-700 was revised to meet the AWPA standard.

Comment: NMWPC, Timber Products Inspection and TEC mentioned that the wording in paragraph 9.6.2 of Bulletin 1728F-700 be revised from “supplemental groundline type preservative” to “a preservative approved for use in ground line contact by the AWPA.”

Agency Response: Wording was revised to use “a preservative approved for use by AWPA.”

Comment: Lee Inspection, NMWPC, Timber Products Inspection and AWW felt to certify inspectors and quality control personnel on the use of XRF equipment was unreasonable.

Agency Response: RUS agrees that this requirement may be difficult to achieve because there is no organization set up to perform this service. This provision was eliminated.

Comment: McFarland and TEC raised questions about the addition of the inspection agency's designation on the face brand and the use of tags.

Agency Response: This requirement does not add an extra line to the face brand. It replaces the Quality Assurance mark currently required on the second line of the brand. Treaters will be given 6 months from the publication date of this notice to revise their face brands. For treaters using metal tags, if the existing tag cannot be altered to show the independent inspection agency designation a separate tag showing this information shall be added. Metal tag users have three months to start revising their current tags or ordering an additional tags to show the agency information.

Comment: Lee Inspection disagrees with the RUS's proposal to not allow one independent inspection agency to subcontract their contracted inspection to another party.

Agency Response: When an Electric Borrower designates an inspection agency to act as their agent and inspect pole on their behalf the RUS believes they actually want that company to do the work. RUS believes that this requirement is reasonable.

Comment: Lee Inspection disagrees with the RUS's stand on not allowing independent inspection agencies to offer product warranties on inspected material.

Agency Response: RUS wants, as a secured lender, to eliminate any appearance of a conflict of interest between independent inspectors and Start Printed Page 36963treaters. A product warranty put out by an inspection agency for a pole or crossarm produced by another company is unacceptable. RUS is not changing this provision.

Comment: Lee Inspection and AWW are concerned with the wording “Failure of a selected third-party inspection agency to properly perform their required overview responsibilities may subject said agency to subsequent liability claims for unsatisfactory or inadequate product performance.”

Agency Response: This specific language will be from the final rule, however, the potential liability incurred by the inspection agency for any improper performance will be left up to the borrower.

Comment: Lee Inspection and AWW felt the frequency of the precision check by independent inspectors for the x-ray fluorescence instrument at treating plant weekly was too onerous.

Agency Response: In some cases this requirement could be too burdensome. In response, the frequency was changed to monthly for analysis of preservative and treated wood at the inspector's agency laboratory.

Comment: Cox Industrial Group and Dis-Tran wanted to require borrowers to store crossarms under cover to be eligible for the one year warranty.

Agency Response: The conformance period of one year from date of delivery should not be affected if arms are stored indoors, outdoors or installed on poles. As a result, RUS will not change the proposal.

Comment: Timber Products Inspection noted that the radial drilling depths were left off Table 10 in Bulletin 1728F-700.

Agency Response: This information was added back into the bulletin.

Comment: McFarland Cascade questioned the limiting of butt treated poles to arid regions.

Agency Response: Since butt treated poles have shown to have good durability in areas other than arid regions the final rule is revised to limit their use to low to moderate decay zones.

Comment: McFarland Cascade and Timber Products questioned allowing through boring for poles were raised.

Agency Response: In response to this, a section on allowing through boring was added.

Comment: WQC suggested that the Insured Warranty program be removed since it has not been used in many years.

Agency Response: This plan for supplying poles has continued to be included to keep several options open for suppliers. There have been a few instances where suppliers have tried to start using this program again.

Comment: WQC suggested that RUS limit the percentage of defects of a “lot” of poles from 15% to 5%, which is the AWPA limit, before the entire lot is rejected.

Agency Response: In response, RUS will revise their reject percentage to stay in line with AWPA Standards.

Bulletin 1728H-702, Specification for Quality Control and Inspection of Timber Products.

(a) Scope. This specification describes in more detail the responsibilities and procedures pertaining to quality control for crossarms, as specified in section 1728.201 of this part, and poles, covered in Bulletin 1728F-700, “Specification for Wood Poles, Stubs and Anchor Logs,” incorporated by reference in § 1728.97 of this part and in § 1755.97 of 7 CFR part 1755.

(b) General stipulations. (1) Conformance of poles and crossarms to agency specifications for the most part is the responsibility of the producer's management.

A member of the producer's staff shall be designated quality control designee and charged with the responsibility for the exercise of proper quality control procedures.

(2) The requirements of AWPA M3-05 (incorporated by reference at § 1728.97), covering records, adequate laboratory, plant gauges, and other plant facilities including proper storage, shall be followed.

(3) The methods of inspection described in this section shall be used no matter which plan timber products are purchased under, i.e., Insured Warranty Plan, Independent Inspection Plan, or Quality Assurance Plans, as described in § 1728.201 of this part or Bulletin 1728F-700 (incorporated by reference at § 1728.97). The number of poles and crossarms actually inspected by monitors for quality control under a Quality Assurance Plan or the Insured Warranty Plan may vary from the number of poles and crossarms inspected under the Independent Inspection Plan. Under the Independent Inspection Plan, each pole and a sample number of crossarms shall be inspected.

(4) 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 for purchase under the Independent Inspection Plan, the treating company shall obtain the services of an inspection agency.

(5) Individual inspectors in the employ of Independent Inspection Agencies shall be experienced and competent. The inspector shall perform all phases of the inspection personally and in the proper sequence. The primary responsibility of the inspector is to determine, for the borrower, by careful inspection and verification, that the timber products, preservative, and treatment meet the requirements of Bulletins 1728F-700 (incorporated by reference at § 1728.97) and § 1728.201 of this part (Bulletin 1728H-701) and that the methods, storage facilities, and production equipment conform to applicable specifications. For details of the inspector's qualifications see Appendix A of this section.

(6) Independent inspection agencies and inspectors shall maintain their impartiality. To do so, inspection agencies, inspectors, producers and brokers must maintain the greatest degree of separation and eliminate even the appearance of a conflict of interest. Inspection agencies shall not receive gratuities from or enter into financial agreements, other than for inspection services, with suppliers for which they perform inspection. Inspection agencies shall not provide gratuities or free services to suppliers. Inspection agencies shall not offer product warranties on inspected material.

(7) Failure of an individual inspector to follow proper procedures or failure of an inspection agency to properly train and supervise inspectors or follow the appropriate RUS specifications constitutes grounds for RUS debarment of said company from future inspection of RUS financed material

(8) 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. Upon request, evidence of compliance to this requirement shall be forwarded to the agency. 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).

(9) Inspection agencies shall maintain their own laboratory that is properly equipped, and capable of completely analyzing the respective preservatives and retentions, and at a minimum able to run referee methods. This laboratory shall be independent from any treating plant laboratory. Independent Inspection Agencies may use one central laboratory.

(10) Laminated materials manufactured for use on borrower systems shall comply with manufacturing and quality control requirements specified in ANSI O5.2 (incorporated by reference in § 1728.97). The product shall be marked and certified.

(i) Laminated material shall be inspected in accordance with ANSI O5.2, (incorporated by reference in § 1728.97).

(ii) Quality control of material shall be performed to determine conformance with § 1728.201 of this part and AITC 200, (incorporated by reference in § 1728.97).

(c) Quality control and inspection procedures for product acceptance. It is the responsibility of the plant quality control designee 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 designee has performed these procedures, a particular lot of material shall be released to the inspector for verification of conformance.

(1) Poles can be purchased under any of the three purchase plans. These plans are Insured Warranty Plan, Independent Inspection Plan, or a Quality Assurance Plan. Under all of these plans, all poles in a lot shall be inspected by the plant quality control designee.

Under the Insured Warranty Plan and a Quality Assurance Plan, the number of poles inspected by a third party inspector may be less than every pole, depending on the terms of the plans.

(i) Ample space and assistance shall be provided by the treating plant for Start Printed Page 36973handling and turning to ensure that the surfaces of all items can be adequately inspected.

(ii) Under the Independent Inspection Plan, all poles shall be inspected by the Independent Inspector for conformance to the requirements of Bulletin 1728F-700 (incorporated by reference at § 1728.97). If a pole is rejected and the cause of rejection is corrected, the rejected pole may be offered again for inspection as new material.

(iii) Dimensions, length, and circumference shall be measured by a standard steel tape to determine that they are in agreement with the details for class and length in the brand and butt stamp. If it is obvious by visual comparison with a measured pole that the brand information is correct, individual poles need not be measured. Pole circumference dimensions made prior to treatment shall govern acceptance. Reduction in dimension due to treatment and shipping shall be not more than 2 percent below the minimum for the pole class.

(iv) If 5 percent of the poles in a lot offered for inspection are defective, the inspector shall terminate the inspection. Re-examination of an entire lot by plant quality control shall be required when the number of rejected poles equals or exceeds 5 percent of the lot inspected. All defective or nonconforming poles either shall be removed from the lot or have their brands marked out.

(v) Poles in a lot shall be inspected for decay and all poles shall be of the same seasoning condition. If the plant quality control designee suspects that decay is present, a slice from both ends shall be cut for closer examination. If 3 percent of the inspected poles in a lot show evidence of decay, the entire lot shall be unconditionally rejected without further sorting.

(vi) Moisture content, when limited by the purchaser, as stated on the purchaser's purchase order, shall be measured by calibrated electronic moisture meter. Calibration of the 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.

All non-conforming arms shall be rejected. Whenever the number of nonconforming arms is found to exceed 0.5 percent of the lot or one arm, whichever is greater, the entire lot shall be rejected for excess number of defective ends. After the producer has removed or marked out the defective material, the arms may be resubmitted for inspection.

(B) Surface inspection of the lengthwise sides performed on a random representative sample. The sample size shall equal 20 percent of a lot size or 200 arms, whichever is smaller. The inspector shall examine side surfaces as they are slowly rotated. When necessary, the rotation may be stopped for closer inspection. All non-conforming arms shall be rejected. Whenever the number of nonconforming arms is found to exceed 2 percent of the sample size, the entire lot shall be rejected. After the producer has removed or marked out the defective material, the arms may be resubmitted for inspection.

(C) Check of moisture content of the random sample by a calibrated moisture meter.

(D) Check of crossarm dimensions of the random sample measured after surfacing.

(ii) Inspection during manufacture shall consist of:

(6) If used for analysis, x-ray fluorescence instruments (XRF) shall be accurate and reliable, and they shall generate reproducible results. Instruments shall have thorough instructions which should include recommendations on drying techniques, equipment, and density calculations. These drying recommendations shall be followed when using XRF instruments.

(7) To check the precision and accuracy of the in-plant x-ray fluorescence units (XRF) being used by producers, at least once monthly the independent inspector shall take a retention sample previously analyzed in the producer's laboratory and rerun it in the inspection agency's own laboratory. This sample shall be run utilizing either the XRF or recognized referee method for the given preservative. If the analytical results are within ± 5% of retention value that was previously obtained on the sample using the plant's XRF unit, the plant instrument needs no further calibration. All XRF units maintained by independent agencies as part of their required laboratories shall be calibrated at least quarterly either by the referee method for each preservative treatment being analyzed by said agency or by comparison with a set of graduated treated wood standards.

(8) Each independent inspector and plant quality control personnel that use XRF instruments, shall be properly trained in the analysis of treated wood and preservatives under the supervision of a competent instructor. Proof of training shall be kept on file.
