Section 1.0 THREE STAGES OF CLP’S SERVICE CONNECTION PROCESS The electrical distribution utility systems at Hill AFB and the Utah Test and Training Range were sold to City Light & Power (“utility system owner”) as part of the USAF Utilities Privatization (UP) effort. Therefore, the utility system owner is the sole provider of these utility services to the installation and should be viewed just like any other local utility. This manual contains guidance and tips for transparent and successful interactions with the system owner.

City Light & Power is proud to be part of the Hill AFB engineering team. We strive to help deliver successful construction projects. We established procedures to facilitate that project delivery.

Newly installed system infrastructure and modifications of or connections to existing system infrastructure identified in the specifications and drawings must be coordinated with the utility owner prior to the contract start date. The utility owner must be integrated into the design, inspection of construction, tie-in to existing utilities and conveyance of any exterior utilities. The preferred process for connecting facilities is to request that the utility owner install the required connecting facilities up to a point of demarcation to be identified by the Government, as a connection charge. Any fees associated with connecting contractor-constructed infrastructure to the utility owner’s system must be negotiated with the utility owner. All work on the system or facilities expected to connect to the system shall comply with the utility owner’s specifications and construction standards. In no event shall a contractor cap, connect to, or otherwise touch the utility owner’s infrastructure without the utility owner’s express written permission.

The utility owner can be contacted at:

City Light & Power, Inc.

7814 North Drive (Bldg 2726) Hill AFB, UT 84056 rhh@clpinc.com

(801) 660-2255 (Office)

In order to install a service connection efficiently, CLP recommends organizing the project into three distinct phases:

I. Initiation–Getting started.

II. Design–Preparing a detailed work plan.

III. Construction–CLP facility installation and site restoration.

Each phase of the process includes requirements that will enable the project to advance to the next step. As with any construction project, informing CLP promptly of any changes to the requirement will allow our representatives to keep our customers informed if there are related scope changes.

1.1 INITIATION

1.1.1 INITIATING A SERVICE CONNECTION

The service connection request begins with a completed service application. (See Appendix A) In order for CLP to meet the service date, submit the service application as early as possible in your planning process. Allow up to 21 days for CLP to review and respond to a service application.

Copies of the Service Application form are available at the CLP office.

mailto:rhh@clpinc.com

Proprietary 1-2

Definition: Point of Demarcation (POD) is a point on the utility system where ownership changes from the utility SO to the facility owner. It is the physical point where CLP responsibility to maintain ends and the service of the customer begins – this is usually where the secondary cable is physically terminated.

For pre-planning purposes, CLP is typically responsible for all transmission and distribution lines on base. CLP owns the electrical distribution infrastructure, including poles, switches and transformers. PODs are normally located at the secondary terminals on service transformers.

Note: Special point of demarcation rules apply to unique areas of the base. Please, consult with the CLP point of contact at each location to identify proper points of demarcation.

Submit Site/Building drawings along with the service application. The Site/Building drawings shall include, at a minimum, the following information:

• A site plan showing water, sewer, storm drain, building line and preferred transformer location. Include driveways and street names.

• Quantity and Size(s) of transformer(s) requested.

• Planned load (maximum load) requirement of the new installation.

• Single-line drawing of the primary power (existing and new) within the project site.

• Secondary voltage requirement. Following is the list of typical secondary voltage available in CLP systems:

o 1- Phase, 120/240V o 1- Phase, 240/480V, 3-wire o 3- Phase, 208Y/120V, 4-wire o 3- Phase, 480Y/277V, 4-wire

• Contact Information.

1.1.2 PLANNING THE SERVICE CONNECTION

The formal planning process will begin after receipt of a completed service application.

The information obtained in your service application provides CLP an accurate description of the project, including the anticipated electrical requirements.

Step 1: Scoping

• Perform Utility Locate—to avoid utility conflicts as soon as possible in the process.

• Outline Scope of Work—to ensure we understand the project and have all necessary information.

• Verify Application Information—which should include a complete set of plans (site and architectural), load information, billing information, and any existing CLP facilities which may require relocating.

• Specify Transformer—as marked on the site plan. Preferred locations will be considered.

• Develop preliminary Schedule—to ensure CLP can meet your requested service date as proposed.

Step 2: Evaluating

Proprietary 1-3

CLP will evaluate and determine if the existing electrical infrastructure is adequate to meet the request. CLP will then develop an engineering plan or preliminary routing sketch proposing the work plan to meet your request for service.

• A site visit may be required to discuss equipment details.

Step 3: Connection Cost Estimating

CLP will estimate the job costs, labor and materials required to complete the service connection. CLP will then determine the appropriate charges for the installation and contact the service connection request representative with a final job cost.

Step 4: Publishing Connection Fee

CLP will send an estimate and preliminary routing sketch to the customer project representative. The estimate will reflect the connection fee for the service request.

The preliminary routing sketch will reflect the agreed upon transformer and the proposed route for construction.

Step 5: Signing Agreement

After the submittal review process, return the signed estimate/Purchase Order and approved preliminary routing sketch along with the service connection fee. This step will need to be completed before CLP can move forward.

Please note that anytime CLP is required to deviate from CLP’s standard practices and procedures, the service connection requestor will be responsible for all additional costs. For example: design revisions, multiple designs, job scope changes, etc.

1.2 DESIGN

1.2.1 DESIGN STEPS

Step 1: Validating

After CLP receives the signed contract and payment, a CLP Representative will contact the requestor to confirm that the initial information is still accurate.

• Transformer size—if it has changed, make sure CLP has the correct transformer size (kVA).

• Transformer locations—let CLP know if the proposed transformer location has changed.

• Detailed utility site plans—confirm that CLP has the final project site plans with all the other on-site utility lines located: fuel, water, sewer, telephone, electric, geothermal systems, etc. Please notify CLP immediately if any detail of the plan requirements change.

Proprietary 1-4

Step 2: Performing Initial Design

If required, CLP will prepare a detailed electric installation design, including the specific plans needed for our construction crews to perform the work. CLP may attend customers design review meetings for Design/Build and Design/Review/Build projects.

Step 3: Coordinating Design Documents

If required, CLP will send a copy of the final CLP design drawing to the requestor.

Step 4: Delivering Final Design

Return the signed design drawing (if applicable) and any remaining payment due.

Partial payment may be required before construction work will be scheduled if transformers, switches or other hardware is to be installed.

Step 5

CLP will apply for necessary permits required for the installation of the new service connection as applicable. The time this takes varies, depending on the location and type of permit. Any changes subsequent to the execution of the contract, such as significant changes in connected load, voltage class, transformer location, or inadequate site conditions will delay our work and may result in additional costs for re-engineering, design, and/or construction and will have a negative impact on the planned service date.

1.3 CONSTRUCTION

All personnel working on the installation of CLP electrical service lines are trained and certified. If a CLP-approved contractor does the construction work, a CLP inspector will monitor quality control on the site.

1.3.1 CONSTRUCTION STEPS

Step 1: Scheduling

Once the site is ready, notify CLP to schedule construction of your project or to monitor quality control over the electric installation. Contact the local CLP Base Installation Manager or Representative. Please have the Job Number and job address ready.

Step 2: Prepping Site

CLP will complete a Dig Permit if required.

Step 3: Verifying Site Conditions

Proprietary 1-5

After all existing underground utilities are marked prior to CLP starting construction, CLP may need to dig test holes to verify the depth and location of underground lines to avoid damage during construction.

Step 4: Constructing and Installing

CLP will install the electrical lines. Expect heavy equipment to be working around your facility. Crews from CLP or CLP subcontractor crews will install the service connection.

Construction equipment may be left overnight. Holes and trenches may be open during construction for connections and safety testing. All trenches and holes will be clearly marked with safety cones and/or safety fencing.

1.3.2 SITE RESTORATION

CLP will restore your property and will minimize the disturbance of established lawns and pavement wherever practical. While CLP puts much effort not to disturb any existing paving, shrubbery, trees, plants, or lawn, it is not always possible.

Once construction is complete, CLP will restore the affected areas of your property as promptly as possible.

• If sidewalk or roadway sections have to be removed, temporary paving may be necessary. It may take several weeks before permanent paving is completed.

• During winter months, permanent paving may be postponed until the weather is warmer.

The time required for restoration will depend on weather conditions and the extent of the disturbed area.

For any questions please call the CLP Base Installation Manager or Representative (Page i).

Proprietary 2-1

Section 2.0 RESPONSIBILITIES FOR ELECTRIC SERVICE

CLP utilizes Design and Construction Standards based off of the latest Institute of Electrical and Electronics Engineers (IEEE), National Electrical Safety Code (NESC), and National Electrical Code (NEC) requirements.

These standards and requirements are followed to decrease the likelihood of loss-of-life and/or equipment damage. CLP requires all contractors/subcontractors to adhere to these standards.

2.1 STANDARDS GOVERNING INSTALLATION

Follow industry recognized standards set forth by IEEE, NESC, and NEC for all electrical installations.

The NESC requires specific distances between utility facilities, such as overhead lines, and other structures. The distances vary based on the type of utility facilities and the type of structures being put up. It is the contractor/subcontractor’s responsibility to determine the distance requirements. Failing to do so creates a dangerous situation that can also be costly to the responsible party to remedy later.

CLP has an open-door policy for any questions customers, contractors, or subcontractors may have. The ultimate goal for CLP is to install an electrical system safe for everyone and will continue to operate many decades from now.

2.2 ADDITIONS AND ALTERATIONS

CLP’s electrical system has definitely capacity limitations and can be damaged by overloads. Therefore, it is everyone’s responsibility to notify CLP before increasing the load requirements or making alterations to the service entrance equipment. CLP will provide the proper equipment on the electrical system to serve the increased capacity.

2.3 WORKING AROUND HIGH VOLTAGE OVERHEAD LINES

The approach distance and working around high voltage overhead lines the requirements to the activities of utility or non-utility construction personnel are governed by the Occupational Health and Safety Administration (OSHA), National Electrical Safety Code (NESC), federal, state, or local statutes or regulations. Call the CLP Base Installation Manager or Representative (Page i) if work needs to be performed that meets the above qualification.

If work must be performed on an overhead utility line, with prior notice and approval, CLP will initiate proper safety measures, which may include the following:

• Relocating the lines.

• Installing physical barriers to prevent any contact with the lines.

• De-energizing and grounding the lines.

• Other proactive safety steps as necessary.

Proprietary 2-2

• Compliance with safety requirements governed by the Occupational Health and Safety Administration

(OSHA)

Minimum OSHA requirements are as follows:

For lines rated 50 kV or below, minimum clearance between the lines and any part of the crane or load shall be 10 feet for lines rated over 50kV; Minimum clearance between the lines and any part of the crane or load shall be 10 feet plus 0.4 inch for each 1 kV over 50 kV or twice the length of the line insulator but never less than 10 feet;

In transit with no load and boom lowered, the equipment clearance shall be a minimum of 4 feet for voltages less than 50 kV, 10 feet for voltages over 50 kV up to and including 345 kV and 16 feet for voltages over 345 kV up to and including 750 kV in accordance with the CLP Safety Manual.

It is your responsibility to know and abide by all OSHA and local regulations when working in the vicinity of electrical lines.

2.4 COMMON STANDARDS FOR ELECTRICAL DISTRIBUTION WORK ON HILL AFB

2.4.1 PRIMARY VOLTAGE:

The Primary voltage at Hill AFB is 12,470 volts.

Proprietary 3-1

Section 3.0 SERVICES NOT RELATED TO PERMANENT SERVICE CONNECTIONS CLP will perform requested services that are not part of the Permanent Service Connections section. These services are covered here but are not limited to the below.

3.1 TEMPORARY ELECTRIC SERVICE

A temporary service connection can be provided that is either overhead or underground where facilities are available for a non-permanent period. That period will be defined by Base Representatives, Contractors, and CLP. Costs will be the responsibility of the requestor to install and remove the services. CLP is flexible and understands temporary services are project specific.

Please contact the CLP Base Installation Manager or Representative (Page i) for any further questions.

3.2 RELOCATION OF CLP LINES AND EQUIPMENT

Projects requiring underground or overhead electrical infrastructure to be relocated should follow Section 1 of this manual.

Please contact the CLP Base Installation Manager or Representative (Page i) for any further questions.

Proprietary 4-1

Section 4.0 ELECTRICAL SAFETY AND CODE CLEARANCES

4.1 GENERAL

It is the policy of CLP to operate the electric transmission and distribution system with the highest degree of care for the safety to the public and CLP employees. To ensure the care and safety needed for an electric distribution system, the National Electric Safety Code is used for design, construction, maintenance, and operation of the electric system by CLP as well as any applicable practices by the public and private industry. The applicable National Electric Safety Code in effect at the time will apply to new installations and extensions. Existing installations may be altered, replaced for maintenance, or additions made to comply with either the current edition or original requirements of the applicable National Electrical Safety Code in effect at the time of original installation as allowed in NESC Rule 013B.

• CLP reserves the right to temporarily disconnect service when a hazardous condition is discovered.

4.2 MINIMUM CLEARANCE FROM OVERHEAD LINES

• For the purpose of this section, the term “clearance” means the shortest distance between any two surfaces.

• Minimum clearance between any building or other structure and any overhead transmission line, overhead distribution facility, or electric utility pole will be maintained in accordance with the provisions of the National Electrical Safety Code.

• Minimum clearance between signs, chimneys, radio and television antennas, storage tanks and other structures, and any overhead transmission line, overhead distribution facility, or electric utility pole will be maintained in accordance with the provisions of the National Electrical Safety Code.

• Minimum clearance over streets, alleys, parking lots, rights-of-way, easements, etc., of overhead transmission & distribution facilities, will be maintained in accordance with provisions of the National Electrical Safety Code.

• Minimum clearance between over-height vehicles, including house moving, and any overhead transmission line, overhead distribution facility, or electric utility pole of CLP will be maintained in accordance with the provisions of the National Electrical Safety.

4.3 EQUIPMENT OPERATION AROUND ENERGIZED FACILITIES

4.3.1 REQUESTS FOR SYSTEM OUTAGES

CLP on a case-by-case basis may allow individual system elements to be removed from service in order to accommodate construction or maintenance activities. CLP complies with the outage planning policies of the Base

Proprietary 4-2 host installations, which include various forms and scheduling requirements. Under these circumstances, the outage must be planned well in advance, and every effort must be made to minimize the duration of the outage. If at all possible, the construction or maintenance activity shall be conducted in such a manner that the facility can be returned to service immediately in the event of a loss of another system element.

Outages lasting longer than one-week may require the construction of a temporary facility to minimize the required outage time. Outages on system elements that will leave a load serving facility vulnerable under a single additional contingency will require plans to mitigate the next contingency. These plans should restore the load serving capability of the system as soon as possible. All time and material necessary to develop the contingency plan will be paid for by the requesting party. In the event the contingency plan is executed, the requesting party will pay all time and materials associated with service restoration.

Electric transmission systems present a unique challenge in that outage and restoration times will typically require several weeks. On a case-by-case basis, planned outages for the modification of transmission systems may be granted. However, due to the extended nature of these outages, contingency plans for the restoration of load must be in place prior to the planned outage. In some cases, an outage may not be granted, and new facilities may need to be constructed before existing facilities may be abandoned.

4.3.2 OVERHEAD

When working near or operating equipment around overhead electrical lines, Federal OSHA standards require that unqualified persons maintain the electrical distances listed in Column B of Table 4.1 between energized lines/parts and themselves, their tools, their equipment, and all conductive materials. Contacting the line can result in severe injury or death. If work must be accomplished near an overhead electrical line, call the CLP Base Installation Manager (Page i) for assistance as needed to identify line-operating voltage, do not rely on proximity warning devices such as hook insulators or boom guards, because each has its limitations or otherwise avoid contact with these energized facilities. If distribution lines must be de-energized, the customer shall provide a written request to CLP and allow 10 business days for CLP to respond to the request. It is the responsibility of the contractor to apply safety grounds to safely perform work on the de-energized line. CLP does not ground for others to work on the system or assume responsibility for their workers. CLP will de-energize, test and issue a clearance. Requests to de-energize overhead lines should be submitted early in the requester’s planning process and will be reviewed on a case by case basis by CLP and the respective Base Leadership. Transmission outages require a significant level of preplanning and could take weeks to coordinate.

4.3.4 UNDERGROUND

Grading, excavation, ground rod, stake or post installation work will not be started until an underground facilities location has been completed. Digging into or damaging underground power lines can result in severe injury or death to the operator and others, and can cause interruption of service to wide areas. Complete a Base Dig Permit before digging or excavating. Trained personnel from CLP will locate electrical facilities at no cost.

The National Electric Safety Code requires the protection and separation of underground electric supply lines from other structures, including other utilities. Below are typical clearances for parallel utilities, and crossings of utilities.

HIGH VOLTAGE CABLE HANDLING AND STORAGE GUIDE

1. Unloading of cable should be accomplished so that equipment used does not contact either the cable surfaces or the protective wrapping. If unloading is accomplished by crane, either the cradle supporting the reel flanges or a shaft through the arbor hole should be used. If a fork is utilized, the forks must lift the reel at 90 degrees to the flange and must be long enough to make complete lifting contact with both flanges. Under no circumstances should the forks contact the cable surface or protective wrapping. For the same reason, a web-sling arrangement should not be used around the conductor as the weight could damage the cable.

2. Under no circumstances should reels be dropped from the delivering vehicle to the ground.

3. Reels should be stored on a hard surface so that the flanges do not sink into the earth, allowing the weight of the reel and cable to rest on the cable surface. In storing, never turn the reel on the flange side for this will result in cable damage. The reels should be stored upright in a rolling position.

4. Cable should be stored in an area where chemical or petroleum products will not be spilled or sprayed on the cable.

5. When a reel of cable is rolled from one point to another, care must be taken to see that there are no objects on the surface area which could contact or damage the cable surface or protective wrapping.

6. If a length of cable has been cut from a reel, the cable end should be immediately resealed to prevent the entrance of moisture. Use cable seal caps (mastic and vinyl tape (see SC5.3.5).

Installed cable that is not immediately terminated should be sealed, especially if left overnight.

7. Cable should be stored in an area away from open flame or other sources of high heat.

8. Reels should be stored in an area where construction equipment, falling or flying objects, or other materials will not contact the cable.

9. If an inclined ramp is used for unloading, the ramp must be wide enough to contact both flanges completely, and stopping of the reels at the bottom shall be accomplished by using the reel flanges, and not the surface of the cable.

INSTALLATION TEMPERATURE GUIDE FOR PRIMARY CABLES

1. The low temperature weakness of primary cables is the semi-conducting strand and insulation shield compounds, which have a much higher brittleness temperature than the TRXLPE insulation. If a crack initiating in the shield does not propagate through the insulation as might be expected, then immediate failure may not occur and the cable could operate for some time before failure. However, to avoid any possible damage to primary cables while installing or operating cables with elbows at extremely low temperatures, the following guidelines should be used:

A. Minimum temperature of cable during installation for primary TRXLP with thermosetting semicon shield is -25°C

(-13°F).

B. For splicing or terminating primary cables, warm cable ends up to at least 32°F.

C. Primary cables may be operated, such as moving elbows onto a parking stand down to the same low temperature given in "A" above.

D. If any cable damage is suspected during installation, then an additional 12-15 feet of cable should be pulled and delivered to the Standards Laboratory for analysis. The sample must be cut from the leading section of cable to determine if any damage occurred during the pull.

MINIMUM BENDING RADIUS

1. The minimum bending radius of primary cable shall be twelve times the overall diameter of the cable.

2. The minimum radius specified is measured to the surface of the cable on the inside of the bend.

3. These bending radii are to be considered minimum recommended dimensions and are for static bends such as manhole training bends, etc., and do not apply where pulling tensions and sidewall pressures are involved.

4. To visualize a bending radius, determine the diameter of the cable and multiply by twelve. Use this dimension as the minimum bending radius. Scribe a circle on the floor or in the dirt and form the cable around it. See cable bending radius in the tables on SC5.4.2.

ENERGIZING NEW CABLE

1. Since DC Hipot testing of cable and accessories can lead to insulation damage, this method is NOT reccommended for testing cables. A TDR (Time Domain Reflectometry) test set should be used to verify continuity and the integrity of the circuit. It is recommended, if possible, to energize new cable for one day at rated line voltage, prior to loading.

TEMPORARY CABLE END CAPS FOR WATER SEALING PRIMARY CABLES

Aluminum strands can be seriously affected by water. Oxidation takes place, pitting and eroding the aluminum and in some cases, completely oxidizing the strands leaving only a residue. Moisture in cable has been found to be one of the principal causes of "treeing" in the insulation, leading directly to cable failure. Moisture can also migrate to the termination device causing intermittant feeder tripping prior to failure.

Once a small amount of moisture has entered the cable, the damage has begun. Therefore, it is imperative that cable ends never be left exposed to the elements when cable terminations or splices are not immediately going to be made. Every effort must be made to seal exposed cable ends at once to prevent moisture entry.

The cold shrink end caps shown below are for temporarily sealing the ends of aluminum cable during installation and storage to prevent the entry of moisture. In all cases, the cable end must be clean and dry before the cap is installed. Cables shall not be left exposed overnight during installation work.

All cable manufacturers are required by industry standards to seal the ends of all primary underground cable leaving their factory. Cable shipments must be inspected upon arrival for cable damage or loss of the seal caps.

Replacement caps shall be installed where missing, to prevent further entry of moisture. Notify CLP Engineering to followup with the supplier.

When installing primary cable end caps that are not prefilled with mastic, wrap the cable area to be sealed with several wraps of mastic tape. Finish by installing the cable end cap per manufacturer's instructions.

3. For specify 35kV cables shall consult with CLP engineer for further assist on 35kV, 133% insulation, 420 mils if required for the application.
