treated wood samples for calibration of an XRF used for penta analysis. The Agency wants to note that this is for calibration of XRF units and does not relieve the inspection agencies from the requirement that they maintain laboratories that are properly equipped to run the listed referee methods. As listed in the table above, XRF will be an allowable method for penta. AWPA
A83 in the paragraph will be replaced with AWPA A83 or AWPA A9.
IV. Summary of Changes In addition to the final rule changes published in the Federal Register on June 18, 2019, the following is a summary of other changes to these three bulletins as a result of public comments and Agency clarifications:
1. All references cited in these bulletins are updated to the latest edition in 7 CFR 1728.201, Bulletin 1728H701 and 1728.202 Bulletin 1728H702 or the latest version is used in Bulletin 1724F700
incorporated by reference at 1728.97.
2. AWPA approved 4,5 Dichloro-2-noctyl-4-isothiazolin-3 one DCOI is included in 1728F700 incorporated by reference at 1728.97, 7 CFR 1728.201
Bulletin 1728H701, and 7 CFR
1728.202 Bulletin 1728H702 as a new preservative to address the discontinuation of Pentachlorophenol, another preservative.
3. AWPA A3018, Standard Method for the Determination of 4,5 Dichloro-2n-octyl-4-isothiazolin-3 one DCOI in Wood and Solutions by High Performance Liquid Chromatography, is incorporated by reference in 1728.97
to support the inclusion of DCOI as a RUS approved preservative in Bulletin 1724F700 incorporated by reference at 1728.97 and 7 CFR 1728.202 Bulletin 1728H702.
4. ANSI O5.1 language on ring count is added as an alternate referee method to determine a non-uniform growth rate in Bulletin 1728F700.
5. Table 8 in Bulletin 1728F700 is updated to be consistent with the upcoming AWPA Standards, 2021.
6. An Analytical Method column is added in Table 1 to Paragraph b10 for those preservatives in 7 CFR 1728.202
Bulletin 1728F702.
7. In Bulletin 1728F700, Section 8.d.3.a, to clarify the dimension from b For Group B poles Those poles with a circumference of more than 37.5
inches at 6 feet from butt; will now read b For Group B poles Those poles with a circumference of 37.5 inches or greater at 6 feet from butt.
8. In 7 CFR 1728.202 Bulletin 1728H
702, a supplemental correction is made to include a paragraph on quality marks

on crossarms. This is not a new requirement. The quality marks have been applied as an industry practice.
The paragraphs in Section g, have been renumbered with the addition of a new clarifying paragraph below.
Third-party inspectors shall verify their acceptance of untreated crossarms that have been offered by the producer as conforming by marking each accepted piece in one end with a clear, legible hammer stamp. Following treatment, inspectors shall verify their acceptance of treated crossarms that have been offered by the producer as conforming by marking each accepted piece in the opposing end with a clear, legible hammer stamp. The inspector shall personally mark each piece for acceptance and shall not delegate this responsibility to any other individual.
9. Changes relevant to Bulletin 1728F700 incorporated by reference at 1728.97, 7 CFR 1728.201 Bulletin 1728H701, and 7 CFR 1728.202
Bulletin 1728H702:
Specifications requiring that all thirdparty 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 thirdparty 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.
Incorporation by Reference Bulletin 1728F700, RUS
Specification for Wood Poles, Stubs and Anchor Logs. This specification describes the minimum acceptable quality of wood poles, stubs, telephone pedestal stubs, and anchor logs hereinafter called poles, except where specifically referred to as stubs or

ANSI O5.22020, Structural Glued Laminated Timber for Utility Structures, covers requirements for manufacturing and quality control of structural glued laminated timber of Southern Pine, Coastal Region Douglas Fir, Hem Fir and other species of similar treatability for electric power and communication structures.
ANSI standards are reasonably available to obtain by calling 212642

AWPA A620, Method for the Determination of Oil-Type Preservatives and Water in Wood. This method is suitable for the determination of creosote, petroleum, and their solutions in treated wood when the sample contains at least 5.0 grams of wood and one gram of oil. Preservatives, such as copper naphthenate, or pentachlorophenol or DCOI, may not be quantitatively extracted by this method.
The method can also be used for the determination of water in treated or untreated wood, but when it is so used, the directions on handling the sample in Standard M2 must be followed carefully.
AWPA A920, Standard Method for Analysis of Treated Wood and Treating Solutions By X-Ray Spectroscopy. This method provides for the non-destructive analysis of treated wood and treating solutions by X-ray fluorescence spectroscopy and is applicable to the determination of elements of atomic number 5 or higher that are present in significant quantity in the wood usually above 0.05%. The elements covered in this method are specified for use in preservative and fire-retardant treatment of wood.
AWPA A1519, Referee Methods.
Referee methods are given to assist in the resolution of disputes over the acceptability of the actives in treated wood products.
