Title: 7 CFR Parts 1728 and 1755.Start Printed Page 56514
OMB Control Number: 0572-0076.
Type of Request: Revision of a currently approved information collection package.
Abstract: The Agency has a tremendous amount of interest in loan security and protection of the Government's interest over the long term life of a loan, which is generally secured by a first mortgage security instrument and amortized over a period of up to 35 years. Therefore, the Agency necessarily has a strong interest in the business, financial, and operating aspects of its borrowers.
The Agency proposes to revise its regulations on Electric and Telecommunications Standards and Specifications for Materials, Equipment and Construction, by codifying specifications for wood poles, stubs and anchor logs, wood crossarms (solid and laminated), transmission timbers and pole keys, and for quality control and inspection of timber products. The Agency is proposing to update these specifications to conform with revisions in the industry and to follow Agency policy on insurance requirements.
Respondents: Businesses and Not-for-profit institutions.
Estimated Number of Respondents: 25.
Estimated Number of Responses per Respondent: 1,600.
Estimated Total Annual Burden on Respondents: 40,000.
This estimated total annual burden is a decrease of 363 due to the changes in the requirement that borrowers submit an annual summary report and reserve stock notices on timber specifications.
Copies of this information collection can be obtained from MaryPat Daskal, Program Development and Regulatory Analysis, at (202) 720-7853.
All responses to this information collection and recordkeeping notice will be summarized and included in the request for OMB approval. All comments will also become a matter of public record. USDA Rural Development is committed to the E-Government Act, which requires Government agencies in general to provide the public the option of submitting information or transacting business electronically to the maximum extent possible.

National Environmental Policy Act Certification
The Administrator of the Agency has determined that this proposed rule will not significantly affect the quality of the human environment as defined by the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.). Therefore, this action does not require an environmental impact statement or assessment.
Catalog of Federal Domestic Assistance
The program described by this proposed rule is listed in the Catalog of Federal Domestic Assistance Programs under No. 10.850, Rural Electrification Loans and Loan Guarantees, No. 10.851, Rural Telephone Loans and Loan Guarantees, and No. 10.852, Rural Telephone Bank Loans. This catalog is available on a subscription basis from the Superintendent of Documents, the United States Government Printing Office, Washington, DC 20402-9325, telephone number (202) 512-1800.
This proposed rule contains no Federal mandates (under the regulatory provision of Title II of the Unfunded Mandates Reform Act) for State, local, and tribal governments or the private sector. This rule is not subject to the requirements of section 202 and 205 of the Unfunded Mandates Reform Act.
The Agency 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 proposed major changes to these three bulletins are as follows:
1. All references cited in these bulletins would be updated to the latest edition.
2. The definition “pole broker” would be 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. Proposing to allow borrowers six months to notify treating plants about poles not meeting the required preservative retention.
4. In accordance with Agency policy on insurance requirements for contractors working for borrowers, the specification would be revised to require manufacturers and inspection agencies to maintain certain limits of liability and errors and omission insurance.
5. All poles would be required to be sterilized during the conditioning or treating cycle. This sterilization should reduce the number of poles with pre-treatment decay.
6. The independent inspection agency's identification on the face of the pole would be branded.
7. The Agency would revise the qualifications for inspectors and quality control personnel and would return to prior qualifications of the specifications.
8. Provisions would be 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.Start List of Subjects

(c) 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. 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.
(2) The requirements in American Wood Protection Association (AWPA) Standard M3, 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. 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. This service shall not be subcontracted to another agency. 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, competent and employed by only a single inspection Agency. 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 Start Printed Page 56525borrower, by careful inspection and verification, that the timber products, preservative, and treatment meet the requirements of Bulletins 1728F-700 and 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 supervise inspectors or follow the appropriate specifications are grounds for debarment of inspection of agency 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 according to AWPA standards, capable of completely analyzing the respective preservatives treatments, and at a minimum 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 O5.2-1996 (R2001), American National Standard for Wood Products—Structural Glued Laminated Timber for Utility Structures. The product shall be marked and certified.
(i) Laminated material shall be inspected in accordance with ANSI O5.2-1996 (R2001).
(ii) Quality control of material shall be performed to determine conformance with § 1728.201 of this part and AITC 200-2004, Inspection Manual.
(d) 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 in a lot actually 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 handling 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. 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 15 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 15 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 has occurred, a slice from both ends shall be cut for closer examination. If 5 percent of the inspected poles in a lot shows 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.
(vii) Material failing to conform for moisture content may be retested upon request after a recalibration of the instrument. The results of the second test shall govern disposition of the lot.
(viii) Re-examination for any mechanical damage or deterioration and for original acceptance shall be conducted on timber products not treated within 10 days after original inspection.
(2) Crossarms can be purchased only under either of two purchase plans. These plans are the Independent Inspection Plan or Quality Assurance Plans. Under the Independent Inspection Plan, crossarms are to be inspected prior to manufacture, during manufacture, and after treatment. Under a Quality Assurance Plan, crossarms are monitored according to the terms of the quality assurance program acceptable to Rural Development Utilities Programs.
(i) Inspection prior to treatment shall include:
(A) Surface inspection of all ends of all arms. This is usually done on the stacks of arms prior to manufacture. Particular attention shall be paid to defects commonly found in the ends, such as compression wood, red heart and other forms of decay, shakes, splits, through checks, scantiness, honeycomb, and low density, determined by rings per inch and percent of summerwood. 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 Start Printed Page 56526sample 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. 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:
(A) Checking bolt and insulator pin holes for squareness and excessive splintering;
(B) Checking brands for completeness, location, and legibility; and
(C) Checking arms for conformance.
(iii) Under the Independent Inspection Plan, there shall be a final inspection after treatment for preservative retention and penetration and for damage.
(3) Structural glued laminated timber shall be tested and inspected in accordance with AITC 200, Inspection Manual. Grade of lumber shall be inspected by a qualified grader for specified quality, and so marked, in accordance with grading rules of the American Lumber Standards. Adhesives used for all structural arms shall meet requirements of ANSI O5.2-1996 (R2001) paragraph 5.2. Melamine urea adhesives shall not be used. End joint spacing and limitations shall be in accordance with ANSI O5.2-1996 (R2001).
(e) Preservatives. (1) Creosote shall conform to the requirements of AWPA Standard P1 when analyzed by AWPA Standard Al, sections 2, 3, 4, either 5 or 9, and 6, as follows:.

(2) Solutions of waterborne preservatives shall be analyzed for components in accordance with AWPA Standards A2, A9, or A11, and shall meet the requirements of P5 for composition. AWPA A2 shall be used as a referee method.
(3) Pentachlorophenol shall contain not less than 95 percent chlorinated phenols and should conform to AWPA Standard P8 in hydrocarbon solvent AWPA P9 Type A.
(4) Copper Naphthenate in hydrocarbon solvent (AWPA P9 Type A) shall contain not less than 6 percent nor more than 8 percent copper in the form of Copper Naphthenate and shall conform to AWPA Standard P8 when analyzed in accordance with AWPA Standard A5.
(f) Plant facilities and inspection during treatment. (1) Manufacturing and treating plant facilities shall conform to AWPA Standard M3, paragraph 3. Pressure plants shall be equipped with recording instruments to register time, pressure, temperature and vacuum during each cycle of treatment. Pressure plants shall also be equipped with indicating thermometers and pressure and vacuum gauges to check the accuracy of the recorders. Work tanks shall be equipped with a thermometer. Thermal treating vats shall be equipped with a time and temperature recorder and with an indicating thermometer. Temperature recording devices are not mandatory for plants treating exclusively with waterborne preservatives.
(2) Temperature and humidity readings throughout the kiln shall be recorded on a recording chart and verified by observation of direct reading equipment. Gauges and recording equipment shall be calibrated annually.
(3) Under the Independent Inspection Plan, the inspector shall be present during the treatment procedure, except at times when it may be impractical, such as during late night or early morning treatments. At such times of absence, temperature, pressure, and vacuum data shall be taken from the recording charts.
(4) Recording instruments shall be checked with calibrated indicating gauges and thermometers, per AWPA standard M3. Inaccuracies shall be referred to the treating plant for prompt correction. If an inaccuracy which indicates error resulting in non-compliance with this specification indicating possible damage to the material, the inspector shall reject the charge.
(g) Results of treatment. (1) Poles shall be tested for retention and penetration by means of a calibrated increment borer 0.2 inches ± 0.02 inches in diameter in accordance with procedures in AWPA Standard M2. Under the Independent Inspection Plan, all treating charges shall be tested for retention and penetration. Plant quality control and independent inspection shall do their analyses separately. Under the Insured Warranty Plan and Quality Assurance Plans, the frequency of testing retention and penetration may vary according to the Agency approved plan.
(i) Unless otherwise specified, borings shall be taken approximately 1 foot above the face brand to 1 foot below the face brand. For pressure treated Western Red Cedar and all butt treated poles, borings shall be taken approximately 1 foot below groundline.
(ii) Penetration compliance shall be determined in accordance with AWPA Standard A3. Chrome Azurol S and Penta-Check shall be used to determine penetration of copper containing preservatives and penta, respectively.
(iii) Retention sampling. (A) When there are 20 or more poles in the treating charge, the retention sample for creosote shall consist of 20 assay zones from southern pine and Douglas-fir poles. All poles in charges with fewer than 20 poles shall be bored once. Charges with less than 15 poles shall be bored once and bored again on a random basis to obtain a minimum of 15 assay zones.
(B) Retention samples shall be taken from 20 poles in charges of 20 or more poles.
(C) Retention samples for Alaska yellow, western red, and northern white cedars shall consist of a minimum of 30 assay zones for creosote and waterborne preservatives. For penta charges of fewer than 30 poles, the sample shall contain the assay zone from each pole in the lot.
(D) Retention samples shall consist of borings, representative of pole volumes for each class and length in the charge. Further selection and marking of poles of mixed seasoning, volume, and location on the tram shall be made as illustrated in the following table:
|Number of poles||Class/length||Vol. in cu. ft.||% of total volume||Number of borings|
|Start Printed Page 56527|
|* If a portion of these poles were green and some partially seasoned, then the number of borings should reflect the approximate percentage of each.|
(iv) When material in a lot consists of fewer pieces than the designated minimum number of samples for assay, additional borings shall be taken so as to make up at least the minimum sample, and in such manner that the sample is representative of the lot of material with respect to any variations in size, seasoning condition, or other features that might affect the results of treatment.
(v) Analyses for preservative retention shall be performed as follows:
(A) Creosote retention shall be analyzed by AWPA Standard A6;
(B) Penta retention shall be analyzed by AWPA Standard A5 or A9. Copper pyridine method is required when timber may have been in contact with salt water and for all species native to the Pacific coast region, unless the raw material invoice specifically states that the material either has not been in contact with salt water or has been shown by analysis to have contained no additional chlorides before treating;
(C) Copper Naphthenate retention shall be analyzed by tests in accordance with AWPA Standards A5 or A9;
(D) Waterborne preservatives retention shall be analyzed by tests in accordance with AWPA Standards A2, A7, A9, or A11; and

(vi) Penetration sampling of poles. (A) Group A poles consist of poles with a circumference of 37.5 inches or less at 6 feet from butt.
(1) Bore 20 Group A poles or 20 percent of the poles, whichever is greater. Accept if 100 percent of the sample conform; otherwise, bore all poles.
(2) Re-treat the charge if more than 15 percent of the borings are found to be nonconforming.
(3) Re-treat all nonconforming poles if 15 percent or fewer fail the requirement.
(B) Group B poles consist of poles with circumference greater than 37.5 inches at 6 feet from the butt.
(1) For Group B poles 50 feet and shorter, bore each pole and re-treat only those found to be nonconforming, unless more than 15 percent fail; in that case, re-treat the entire lot.
(2) For Group B poles longer than 50 feet, bore each pole twice at 90 degrees apart around the pole and accept only those poles conforming to the penetration requirement in both borings. All nonconforming poles may be re-treated only twice.
(vii) All holes (nominal 0.2 of an inch diam. bit) shall be promptly filled with treated, tight-fitting wood plugs.
(2) Under the Independent Inspection Plan, all treating charges of crossarms shall be tested for retention and penetration. Plant quality control inspectors and independent inspectors shall do their analyses independently. Under the Quality Assurance Plans, the frequency of testing retention and penetration may vary according to the plan.
(i) The penetration and retention sample shall consist of 20 (48 for creosote) outer 6/10 of an inch for Douglas-fir and 1 inch for Southern Yellow Pine zones from borings taken from any face except the top face at a location as close to the end as possible being at least 3 inches from the end of the arm and no closer than 3 inches from the edge of any holes. For laminated material, borings shall be taken from laminates on a random basis.
(ii) Preservative penetration shall be tested by taking not less than 20 borings from 20 crossarms in each charge, determined in accordance with AWPA Standard A3. Chrome Azurol S and Penta-Check shall be used to determine penetration of copper containing preservatives and penta, respectively.
