LVE CONSTRUCTION INSPECTION PROBABLE VIOLATIONS LETTER- Page 2 of 8 6. 49 CFR 4192.301 Scope. This subpart prescribes minimum requirements for constructing transmission lines and mains. 7. 49 CFR 4192.303 Compliance with specifications or standards. Each transmission line or main must be constructed in accordance with comprehensive written specifications or standards that are consistent with this part. Lower Valley Energy, Welding-Fusion-Mechanical Fitting Manual (June 7, 2017) Section H-HEAT FUSION PROCEDURES 1.1 General The appropriate manufacturer's qualification procedures and fusion procedures are incorporated into this manual by reference. 1.2 Personnel Qualification Company and contractor personnel shall be qualified in the heat fusion process before being allowed to make connections on Company PE piping systems. They must satisfactorily complete an appropriate polyethylene training course which familiarizes them with proper fusion techniques, heat fusion tools and the proper care of these tools. Each individual must submit a sample of each heat fusion procedure the individual is to be qualified for. These fusions will be subjected to visual and destructive testing. 1.4 Equipment When fusing PE pipe, thermostatically controlled electric heating tools shall be used. To verify the accuracy of the heating tools, they shall be checked periodically and when out of tolerance, they shall be calibrated or repaired. All tools shall be properly maintained to guarantee satisfactory operation when making heat fusion joints. The tools shall be kept free of accumulations of dirt and molten plastic residue. 2.2 Equipment C. Flat heating iron calibrated to between 400 Deg F and 450 Deg F with a recommended temperature of 425 Deg F. 2.3 Procedure B. Both surfaces of the heating tool should be free of any accumulation of carbon and plastic residue. L. Verify heating tool temperature. P. Immediately after removing the heating tool, bring the pipe ends together rapidly. DO NOT SLAM. 2.8 Butt Fusion Checklist The following list gives items that should be given special attention when making butt fusion joints: C. Heating tool is clean, and the temperature is 500 Deg F±10 Deg F; LVE CONSTRUCTION INSPECTION PROBABLE VIOLATIONS LETTER- Page 3 of 8 F. Melted ends brought together rapidly. Do not slam. J. To verify the accuracy of the heating tools, check on a regular basis and when out of tolerance, calibrate and/or repair. WL Poly Ethylene Pipe Plastics Joining & Field Procedures For Pipe WL 101 WL 101-0606-Rev Jun 2006 Supersedes all previous editions-2006 WL Plastics Corp.) Pipe Unloading and Handling Observe WL Plastics Unloading Guidelines (WL 111) with WL Plastics pipe products: Use only appropriate lifting and handling equipment that is in safe operating condition,that is properly rated for the load, and that is designed for the intended use. • Do not lift or move WL Plastics products with equipment such as wire rope or chain that can damage the pipe. Equipment that contacts the pipe should be fabric slings or should be rounded or padded to prevent damage to the pipe. • Uncontrolled movement of products or equipment can be hazardous. Never push, roll, dump or drop pipe lengths, bundles or coils off the truck, off handling equipment or into a trench. Always use appropriate equipment to lift, move and lower the pipe. Butt Fusion Procedure -Before starting the procedure, be sure portable generators are fueled up and heating tool surfaces are at the prescribed temperature. Melt the Component Ends Check the heating tool to be sure the heating tool surface are clean and at the prescribed temperature of 400-450 Deg F (204-232 Deg C) Install the hot, clean heating tool between component ends, and move the component ends together and against the heating tool surfaces. Join, Apply and Hold Fusion Joining Force, Cooling When heating time ends as indicated by the correct melt bead size and all around both component ends, use a quick, smooth, continuous action to separate component ends, remove the heating tool,inspect melt surfaces,join acceptable melt surfaces together, and apply fusion joining force. When the heating tool is removed, quickly inspect both melted component end surfaces. A Concave (cupped) melt surface is unacceptable. It indicates pressure applied during heating that can produce a weak, unreliable joint. Do not continue. Allow the melted component ends to cool, and remake the joint from the beginning using correct procedure. Bead Removal Butt fusion produces a bead of material on the inside of the pipe as well on the outside. LVE CONSTRUCTION INSPECTION PROBABLE VIOLATIONS LETTER- Page 4 of 8 Lower Valley Energy, Operator Qualification, Standard Practice No.: 00-20-1, Revision 1, Effective Date April 22, 2020 QUALIFICATION PROGRAM-ELEMENTS PROGRAM ELEMENTS C. Ensuring through evaluation that individuals performing covered tasks are qualified: (a.) The Cooperative requires that any individual working on a covered task be qualified or work under the direction of a qualified individual. In any case, an individual performing a covered task must have demonstrated that they have adequate skills, knowledge, and ability to safely and effectively complete the tasks. D. Contractors and other entities shall be notified via email, mail or telephone of the requirements to provide qualified individuals for the covered tasks to which they will be employed. The cooperative shall verify the quality of workmanship of contractors by providing qualified employees from the cooperative to conduct random field inspections. L. Record Keeping. (a) The Cooperative shall maintain the following records to demonstrate compliance with this subpart: (i) Qualification records shall include: (1) Identification of qualified individuals; (2) Identification of the covered tasks the individual is qualified to perform; Finding(s)• (1) On June 26, 2025, both company and contractor personnel had been actively involved in butt fusion operations and pipeline installation. No documented procedures specific to the construction of transmission lines were made available. Pursuant to 49 CFR Part 192.303, each transmission line or main must be constructed in accordance with comprehensive, written specifications or standards that conform to the provisions outlined in this part. (2) During pipeline staging activities, multiple lengths of fused polyethylene pipe were positioned on a hillside located above the Spider Plow equipment. These pipe segments were subsequently released to descend the slope under gravity. The pipe traversed the terrain, where it encountered obstructions including rocks and debris. One segment made direct contact with the Spider Plow blade during its descent. This impact may have compromised the structural integrity of the affected pipe section, thereby raising concerns regarding its continued suitability for installation. (3) Per 49 CFR §192.273(c) and §192.285(b), individuals assigned to inspect or evaluate joints in plastic piping systems must possess documented qualifications—obtained through formal training or demonstrable experience—specific to the joining procedure being performed. The individual who conducted destructive testing on butt fusion joints prior to August 28, 2025, did not possess the requisite qualifications for that procedure. The certification held LVE CONSTRUCTION INSPECTION PROBABLE VIOLATIONS LETTER- Page 5 of 8 by the individual was limited exclusively to socket fusion and did not extend to butt fusions. (4) While verifying personnel qualifications for conducting butt fusions on 12-inch polyethylene pipe prior to August 28, 2025, certain individuals who had performed butt fusions were not qualified in accordance with the Record of Pipe Joining Qualification Test —Plastic Pipe (192.285) form. Individuals performing plastic pipe joining must be qualified through documented procedures that include both visual and destructive testing, as applicable. The absence of proper qualification may compromise the integrity of the installed pipeline segments. (5) During the verification process of personnel qualifications for performing butt fusion procedures, a material discrepancy was identified within the Record of Pipe Joining Qualification Test — Plastic Pipe (192.285) documentation. The records indicate that destructive testing was conducted in June 2025; however, it was confirmed that the testing equipment was not available or operational until August 2025. 49 CFR §192.285 mandates that qualification testing be performed using appropriate and functional equipment to validate the competency of individuals engaged in plastic pipe joining operations. The premature certification of destructive testing activities without access to the necessary equipment undermines the credibility and regulatory validity of the qualification records in question. (6) Lower Valley Energy, Welding-Fusion-Mechanical Fitting Manual (dated June 7, 2017) referenced manual asserts that it incorporates by reference all applicable manufacturer qualification and fusion procedures necessary to ensure compliance with regulatory requirements governing the installation and joining of polyethylene piping systems. However, upon review, it was determined that the procedure titled WL Polyethylene Pipe Plastics: Joining & Field Procedures for Pipe (WL 101, Document No. WL101-0606-Rev, June 2006)—as published by WL Plastics Corporation and expressly superseding all prior editions—has not been included among the procedures referenced or adopted within the manual. This omission constitutes a failure to fully integrate the manufacturer's most current and authoritative joining procedures as it pertains to fusions involving WL Plastics pipe. Per 49 CFR Part 192, operator procedures must reflect the latest manufacturer specifications governing material handling,joining techniques, and field installation practices. (7) During fusion operations, pyrometers were used to verify the surface temperatures of heating tools. These instruments lacked valid and current calibration documentation. (8) Both contact surfaces of the heating tool must be maintained in a condition free from carbon buildup, plastic residue, or other contaminants that may adversely affect joint integrity. On August 26, 2025, IPUC staff found that both heating plates in use during fusion operations had substantial accumulation of plastic residue. The presence of such contamination constitutes a deviation from prescribed procedural standards, manufacturer guidelines and introduces risk to the reliability of the fusions. LVE CONSTRUCTION INSPECTION PROBABLE VIOLATIONS LETTER- Page 6 of 8 Photographs of the heating tool conditions were submitted to Mr. Coles on the same date for review. (9) A review of the Lower Valley Energy Welding-Fusion-Mechanical Fitting Manual dated June 7, 2017, specifically Section H — Heat Fusion Procedures, revealed that the manual did not include mandatory inspection of melt surfaces for defects such as concave profiles, bubbling, or pock-marking prior to the joining process. The omission of this inspection step constitutes a procedural deficiency and is inconsistent with widely recognized industry standards and best practices governing plastic pipe joining. Such inspections are essential to ensure the integrity of fusion joints and to mitigate the risk of joint failure due to surface irregularities or contamination. Joining procedures must incorporate quality control measures that adequately address pre- join surface conditions.
