LB PROJECT DESCRIPTION The Shungnak-Kobuk Tie Line replaces the old single-phase 7200 volt power line to the community of Kobuk from the generation facility at Shungnak. The 10.5 miles of 7200/12,470 volt three-phase four-wire power line utilizes #2 ACSR conductor supported by 35 foot class 5 wood poles that are secured to W8X48 H-pile Foundations. The W8X48 H-pile is also used for anchoring the angle and deadend structures. 22-097 (07/27/92) 128002/bw 1 [Ke OPERATION The Shungnak-Kobuk Tie Line operates at 12,470 Volts phase-to-phase. Air-break group-operated switches are located at Kobuk and Shungnak to provide line isolation. Over-current protection devices are located at the Shungnak generation facility in the form of line fuses at the transformer bank and fuse-switch at the generator controls. Surge arresters are installed on the line at Shungnak and Kobuk. 1.D TERRAIN AND ELEVATIONS The communities of Kobuk and Shungnak are located on Kobuk river approximately 160 miles east of Kotzebue in northwestern Alaska. The area is characterized by floodplain and lowland terrace at elevations of 200 to 300 feet above sea level. Vegetation is predominantly tundra with boreal forest. The majority of the line route traverses areas of permafrost. ILE SITING/PERMITS The siting and permitting tasks for the project have been performed by the Alaska Energy Authority. IF WEATHER HISTORY / ENVIRONMENTAL LOADING CONDITIONS Weather data was collected from the following three sources: 1) “Climatic Atlas of the United States”, U.S. Department of Commerce. 2) “Design Manual for High Voltage Transmission Lines” REA Bulletin 62-1. 3) “Kobuk-Shungnak, Single Wire Ground Return Transmission Line, Final Report” Thomas D. Humphrey, P.E. Company, 1984. 22-097 (07/27/92) 128002/bw 2 Climatic information is summarized as follows: KOBUK SHUNGNAK Mean Annual Precipitation 1723" 16.2” Mean Annual Snowfall 56” 79.9" Heating Degree Days 16,079 15,539 Freezing Degree Days 6,607 6,300 Maximum Annual Precipitation 61.7 50.6 Minimum Mean Winter Temp (F) -24 -9.3 Minimum Mean Summer Temp (F) 42 48.4 Minimum Extreme Temp (F) -68 -61 Maximum Mean Winter Temp (F) 1 5.7 Maximum Mean Summer Temp (F) 69 68.6 Maximum Extreme Temp (F) 90 90 ICE SEASON Break-up (Span) 5/7 - 5/29 5/12 - 5/29 Average 5/18 5/21 Freeze-up (Span) 10/9 - 11/12 10/7 - 10/25 Average 10/21 10/16 Maximum sunlight (and Civil Twilignt) in the area is 24 hours/day from mid-May to August 1st and 6 hours/day in December. Based on the weather data presented above, and previous discussions with AEA, POWER recommends using the following environmental loads: NESC Heavy - 0.5” radial ice, 4 psf wind NESC high wind - 80 mph (16.4 psf), extreme ice - 1.0” radial ice, no wind. A temperature of -60°F is used as the minimum conductor temperature. 22-097 (07/27/92) 128002/bw 3 1.G EASEMENTS The power line easement width is twenty (20) feet, with ten (10) feet either side of centerline, except at the Bernhardt Lake crossing. The Bernhardt Lake crossing power line easement is forty (40) feet with twenty (20) feet eitherside of centerline, that begins five hundred (500) feet West of the west shoreline and ends five hundred (500) feet East of the east shoreline. Guying easements at PI locations are forty (40) feet and fifty (50) feet, as noted on the Power Line Location maps found in the Specifications & Drawings for Project Erection and Materials document. I.H ACCESS RESTRICTIONS Significant access restrictions apply as the entire project is located within the interior region of Alaska. Access along the power line route is limited to all-terrain vehicles, snow machine and helicopter. Ll THIRD PARTY JOINT USE No provisions have been made for any joint use plans with any communication or cable TV entities. There has been no allowance made in structure strength or ground clearance for the attachment of communications or cable TV. IJ CONTAMINATION The Shungnak - Kobuk Tie Line Project traverses a sparsely populated wilderness area and airborne contamination is assumed minimal. No provisions have been made for mitigating any potential problems. I.K LIGHTNING PROTECTION Keraunic level represents the number of thunder-days per year for the area. It is typically assumed that the number of lightning flashes to earth is roughly 22-097 (07/27/92) 128002/bw 4 proportional to the keraunic level. The keraunic level in the area traversed by the distribution line is less than 10 and therefore surge protection devises installed at Shungnak and Kobak will be suitable for line protection. LL ELECTRICAL EFFECTS AND INTERFERENCE PROJECTIONS This project traverses a wilderness area and is near facilities housing humans only where it enters the villages. Electrical effects (EMF) and radio and television interference (RI, TVI) are considered negligable. 22-097 (07/27/92) 128002/bw 5 SECTION II DESIGN PROCEDURES ILA SURVEY POWER conducted a centerline survey based upon the points of intersection (PI's) as determined by the old power line route. Profile data including all significant planimetric features were inputed into TLCADD for structure spotting and line analysis. 11.B GEOTECHNICAL INVESTIGATION A geotechnical investigation was not performed. However, on site H-pile anchor pull tests were conducted to determine anchor holding capacities. ILC STRUCTURE SPOTTING Structure spotting was completed with the assistance of TLCADD Transmission Line Design Computer Program by Bates Engineering. All structure spotting was based on profile data provided by POWER. 1.D POLE STRENGTH CALCULATIONS Pole strength calculations for determining maximum wind and weight spans for wood poles were completed with the assistance of EPRI’s POLEDA computer program. ILE CONSTRUCTION DRAWINGS Construction drawings for this project consist of REA 8-1/2" x 11” distribution construction drawings and CADD created (computer aided drafting and design) drawings. The CADD drawings are developed using Microstation 4.0. CADD program by Intergraph. 22-097 (07/27/92) 128002/bw 6 SECTION Ill ASSEMBLIES AND MATERIALS LA CONFIGURATION Typical tangent and light angle construction consists of a delta configuration with one phase at the pole top, two phases on the crossarm and the neutral attached below the crossarm brace. The double deadend angle structures are configured with all three phase conductors deadended on the crossarms in a buckarm configuration with the neutral located below the lowest crossarm brace. 1.B STRUCTURE ASSEMBLIES The distribution Pole-Top Assemblies for the Shungnak-Kobuk Tie Line Project are based on the REA C1A series, 3-phase construction drawings (REA specification 803).

Additionally, the minimum requirements of the 1990 edition of the National Electrical Safety Code (NESC) for grade “C” construction were followed where they were more restrictive than REA. V.B CONTROLLING CODES The Shungnak - Kobuk Tie line is designed in accordance with the following codes and standards and general industry practices. If a conflict occurs between the codes for a given application the more stringent code will prevail. - Rural Electrification Association (REA) - National Electrical Safety Code (NESC) - American National Standards Institute (ANSI) - National Electrical Manufacturers Association (NEMA) - American Society for Testing and Materials (ASTM) - American Institute of Steel Construction (AISC) - American Society of Civil Engineers (ASCE) - Institute of Electrical & Electronic Engineers (IEEE) - American Concrete Institute (ACI) - National Environmental Policy Act (NEPA) - Steel Structure Painting Council (SSPC) 22-097 (07/27/92) 128002/bw 10 IV.C LOADING CONDITIONS The following environmental loading conditions were used for design of this project: LOADING CONDITION | ‘ors) | (in) | oy NESC Heavy (Zone) | 4 | 0.5 0 Extreme Wind | 16.4 | 0 60 * Extreme Ice 0 | 1 32 NESC Clearance Wind 6 | 0 60 * Extreme Ice loading conditions are not included in conductor sag and tension data. Ice weight will be assumed to be 57 Ibs/ft.3. Based on the weather data discussed in Section |.F. Weather, History/Environmental Loading Conditions, POWER does not recommend additional design conditions. IV.D OVERLOAD CAPACITY FACTORS The following overload capacity factors (OCF) for Grade C construction are applicable to the loading conditions defined previously: DESIGN OF WOOD POLE NESC HEAVY HIGH WIND HEAVY ICE LOADING CONDITION (16.4 psf) (1") Vertical Load Transverse Wind (Pole) Transverse Wind (Conductor) 1.33 | 1233 | qe 22-097 (07/27/92) 128002/bw 11 DESIGN OF WOOD CROSSARMS LOADING CONDITION NESC & REA Vertical Load Transverse Wind (Conductor) 2.0 Longitudinal Loads (Deadend) | 1.33 DESIGN OF GUYS AND ANCHORS (ANGLE AND DEADEND STRUCTURES) LOADING CONDITION Vertical Loads REA RATED BREAKING STRENGTH OF GUY NESC REA Deadend Loads Transverse Wind 2.0 90% 100% Loads Conductor 1.1 1.15 N.S.

N.S. = Not Specified For each loading situation the design loads are multiplied by the applicable Overload Capacity Factor (OCF) to determine the controlling design load. The high wind and extreme ice load cases have a material strength reduction factor equal to 1.0. 22-097 (07/27/92) 128002/bw 12 IV.E CONDUCTOR DESIGN The distribution phase and neutral conductors consist of No.2 ACSR “Sparate”. The “Sparate” conductor consists of seven (7) strands of 1350 aluminum alloy over one (1) strand of zinc coated high strength steel.

Insulators are sized, based on the maximum design tensions of the No.2 ACSR “Sparate” conductor. Distribution tangent structures utilize crossarm mounted porcelain pin type insulators. Jumper insulators are crossarm mounted pin type. Separate insulation lengths are specified for the distribution and neutral insulators. All insulator specifications meet REA standards. Typical flashover ratings for the distribution insulators are: - 160kV for Low Frequency Dry Flashover - 100kV for Low Frequency Wet Flashover - 250kV for Pos/Neg Impulse Flashover - 260kV for Neg Impulse Flashover IV.G FOUNDATION DESIGN The industry standard of 10% of the pole length plus three and one-half is used for the wood pole embedment in non-permafrost areas of the line. In permafrost areas the foundation type consists of sixteen (16) foot steel H-pile driven ten (10) feet into the ground. The wood pole is bolted onto the six (6) feet of steel H-pile that remains above ground line. IV.H GUYING AND ANCHORING Guyed structure design is based upon the use of 7/16 inch E.H.S. steel (7 strand). The anchors used are of the plate and H-pile type having strengths greater than that of the guy strand. Preformed guy grips are used on the pole end, as well as the anchor end of the guy. 22-097 (07/27/92) 128002/bw 14 IV.I GROUNDING Structure grounding for this project consists of a ground wire attached to the neutral and connected to a ground rod or the steel H-pile foundation. The neutral conductor is grounded to the pole ground at approximately every forth tangent structure and at every angle structure. IV.J CONDUCTOR CLEARANCES All clearance calculations are based on the nominal operating voltage of 12.5kV with a 5% over voltage. The entire project falls below 3,300 feet in elevation, therefore no clearances are increased for elevation. A.

Design Reports are included in the Supporting Calculations Section of this document. V.L POLE STRENGTHS Allowable wind and weight spans for tangent structures have been determined using EPRI’s POLEDAR computer program. A Non-linear analysis was used for determining the allowable wind and weight spans. The following is a partial summary of the input data. Species: Douglas Fir Modulus of Rupture (MOR): 8,000 psi Modulus of Elasticity (MOE): 1,920,000 psi Unit Wt: 40 pcf The Supporting Calculations at the end of this document contain the results of the POLEDAR computer analysis. The maximum weight span for the tangent structures is limited to the maximum vertical load on the unbraced crossarms and not the crossbrace. IV.M CONDUCTOR GALLOPING Conductor galloping phenomenon of distribution conductors is usually associated with lines located in unprotected areas and regions subjected to severe icing conditions. The line route for this project is located in a unprotected area that is 22-097 (07/27/92) 128002/ow 17 susceptible to simultaneous icing and wind conditions. The supporting calculations section of this document contains the galloping analysis. Results of this analysis shows that there is less than a 25% overlap between phase conductors and a 35% overlap between the neutral and phase conductors. Generally, no provisions are made for conductor galloping on distribution lines because of reliability and economics. However, the possibility of conductor galloping occuring in this area exists, so provisions have been made by lowering the neutral conductor attachment, thus providing additional conductor separation. 22-097 (07/27/92) 128002/bw 18 PART Il SUPPORTING CALCULATIONS POWER Engineers ALUMINUM COMPANY OF AMERICA SAG AND TENSION DATA SHUNGNAK - KOBUK TIE LINE 7.2/12.5KV DISTRIBUTION LINE Conductor SPARATE #2 AWG 7/ 1 Stranding ACSR AREA= .0654 Sq.In.

Paul er Energy Authority eae ae AS:jd ANCHOR TEST RESULTS COMMENTS Reference: Memorandum Dated: December 13, 1991 From: Copper Valley Construction Company Procedure: 45 degree pull from D-8 tractor Tension measurement: Dynamometer Deflection measurement: Steel pin located behind anchor Comments: 1) The anchor testing procedures deviate from POWER's proposed anchor testing procedures submitted 11/16/91. The 11/16/91 anchor testing procedures were derived from ASTM standards. 2) Anchors are tested in the guy load direction and not individually tested in the horizontal and vertical planes. Vertical load test results would help determine the anchors uplift holding capacity. Horizontal load test results would help determine the anchors lateral load bearing capabilities. With testing the 45 degree guy load direction, it is difficult to determine in what direction the anchor could fail. Total deflection measured during these test do not delineate the direction of the deflection. 3) The anchor load test performed by the contractor and memorandum submitted to AEA shows that the anchor is capable of carrying the designed guy loads with minimum deflection during winter conditions. Extrapolating this data _ for calculating actual anchor uplift and lateral anchor holding capacities year round is not reliable. Over a period of time it is uncertain how much maintenance may be involved if jacking or lateral movement occurs. Shungnak-Kobuk Protective Device Settings SHUNGNAK - KOBUK PROTECTIVE DEVICE SETTINGS 1. The Shungnak generator breakers are set at 250A trip which does not leave room for proper coordination of any Kobuk line protective devices. GE type TJK 600A/250A trip Set High, High, High Full load current for the three 75kVA single-phase transformers is: 3 (75kVA) = 270A r= V3 (0.48kV) — The present Kobuk line breaker is a Square D Kal 250A/200A trip Set Low, Low, Low This breaker has the possibility of tripping simultaneously with the generator breaker. Addition of any other fuses or reclosers is not recommended unless. A. The Shungnak generator breakers are increased to 400A trip. B. The Kobuk line breaker is increased to a 400a frame with a new breaker set at approximately 300A. C. Two Shungnak machines are running. 2. In general; When two Shungnak machines are on line, the Kobuk line breaker will provide good coordination.
