H2017 Gas and electric underground service installation requirements

CALL PSE’S CUSTOMER CONSTRUCTION SERVICES AT 1-888-321-7779 OR VISIT PSE.COM/CUSTOMERCONSTRUCTION FOR MORE INFORMATION.

Builder/owner/developer responsibilities

PSE requires the following conditions to make the worksite construction ready ahead of scheduled service installation:

Permits

• Fuel line must be in place with an approved permit and plumbed to an approved gas meter location.

A valid permit must be indicated by either:

» A permit visible from outside the structure, or » A green Gas Service Approval sticker affixed to the fuel line.

• Electrical permit must be approved and the Department of Labor & Industries (L&I) sticker must be affixed on the electric meter base.

Meter location

• An acceptable meter location that allows for required access and clearance shall be provided.

» See Gas Meter Clearances and Service Installation Requirements (form 3885) for gas meter locations.

» See Electric Underground Service Installation Requirements (form 6080) for electric meter locations.

Trench work

• The worksite must be prepared to PSE specifications.

» The site must be at final grade or have final grade marked in the area of construction and trench line route.

» For unique site preparation requirements, contact your Project Manager.

» Installation of trench, work pits, sand for bedding and shading, and conduit must meet PSE specifications.

» Sand must be provided by the builder or developer and placed within hand-shoveling distance to the work pit or trench for bedding and shading. (See Sand Requirements for Direct-Buried Installations on page 2.)

» If either gas or electric service will not be provided by PSE, please consult with the other utility for any additional clearance requirements. Use the greater of any conflicting distances.

» Conduit for electric service lines shall be used under all paved surfaces, decks, rockeries, bulkheads, or obstacles to access the service line.

Additional information

• For additional electric service installation information, see Electric Underground Service Installation Requirements

(form 6080).

• For additional gas service installation information and meter set assembly locations and clearances, see Gas Meter Clearances and Service Installation Requirements (form 3885).

• View a video for the proper installation of natural gas piping at this site: pse.com/servicerequirementvideos

Become familiar with what can delay your project and cause it to be red-tagged:

• Construction debris or water in the trench or work pits.

• Trenches excavated to the incorrect depth.

• Failure to maintain minimum separations between utilities and drainage pipes.

• Sand and backfill material are not available, inaccessible, or inadequate.

• Requested meter location is not acceptable or fails to meet minimum clearances.

• Permits are not approved or visible.

• Conduit color and size are incorrect, or conduit is installed improperly.

Sand requirements for direct-buried installations

• The customer shall provide additional clean sand meeting PSE standards in piles that are readily accessible within hand-shoveling distance of each work pit for shading and bedding.

» Sand meeting PSE specification can be found at supplier locations within the PSE service territory and is commonly referred to as “builder’s sand” (ASTM C33). Call PSE’s Customer Construction Services at 1-888-321-7779 for additional sand information.

» Bedding sand will be provided and installed by the customer to a minimum depth of 4 inches prior to the electric and gas direct-buried installations.

» Shading sand is to be installed by the PSE crew after direct-buried electric, gas, or joint service line installation.

Enough sand shall be provided so that the installation can be covered to a minimum depth of 6 inches.

H2017 Gas meter clearances and service installation requirements

CALL PSE’S CUSTOMER CONSTRUCTION SERVICES AT 1-888-321-7779 OR VISIT PSE.COM/CUSTOMERCONSTRUCTION FOR MORE INFORMATION.

• The clearances in this handout also apply to features on buildings adjacent to the building where the gas meter is located.

• Final grade of the service line route must be in place before the service line can be installed.

• If you are unable to meet the meter location requirements in this handout, contact PSE for further assistance.

• Puget Sound Energy reserves the right to designate gas meter locations so that they comply with PSE standards.

• For gas meter installations in Cle Elum and west of Cle Elum within Upper Kittitas County, see the Gas Meter Protection from Snow and Ice in Snow Country handout (form 3736).

Builder/owner/developer requirements

Gas meter locations

Measuring around a building corner

Locate gas meter on the front wall, or within the front 1/3 of the side wall, observing the corner clearance requirements detailed below.

The area 3 feet in front of and 2 feet to either side of the meter set assembly must be free of any landscaping (bushes, fences, etc.) and other structures that restrict access to the meter set assembly.

Outside corners

• The regulator relief vent (see diagram above) should be at least 12" from any outside corner.

» If the regulator relief vent is at least 12" from any outside corner, then there are no minimum clearances to features around the corner.

» If the regulator relief vent is less than 12" from any outside corner, then the minimum clearances specified in this handout must be maintained.

Measure as if using a string

Inside corners

• Clearance distances from the regulator relief vent or meter set assembly to the feature must be maintained in accordance with this handout. Measure as if using a string.

» Conduit bends shall be one long radius, single-piece sweeps (see table below).

» Fittings and elbows shall not be used because the joints prohibit service insertion.

» The sum total of the degrees of bends in the conduit run cannot exceed 180° .

» Conduit shall not cross in the trench.

» Yellow or white Schedule 40 PVC conduit used for gas service lines shall not be marked “water,” or any other utility.

Guard post installation (PSE’s responsibility)

• To protect meter set assembly from vehicle damage, PSE will install guard posts when required.

• To avoid the need for PSE to install guard posts, choose a meter location that is away from driveways or other areas where vehicles travel.

• Guard post requirements are based on the following factors:

» Existing barriers (curbs, guard rails, steep increases in grade, ditches, rockeries, trees, shrubs, chimneys, recessed walls, etc.), which will provide adequate protection;

» Proximity of the facility to the edge of the travel lanes;

» The expected speeds in the travel lanes;

» The width of the travel lane;

» The volume of vehicle traffic;

» Existing nearby building damage or other indicators of vehicle damage that may have already occurred; and, » The type of customer (i.e., single-family residential versus commercial/industrial or multifamily).

• In cases where a meter set assembly will be installed behind a curb, observe the following:

» If the curb will be a rolled curb, and if there is less than 10 feet of space between the curb and the meter, guard posts will be installed; and, » If the curb will have a vertical face, and if there will be less than 5-1/2 feet between the curb and the meter, guard posts will be installed.

• Guard posts will be painted “caution” yellow, especially those located in commercial or industrial locations, street rights-of-way, and alleyways.

1. Guard posts shall be made from steel pipe, 6 feet long, filled with wet concrete and domed on top.

2. In this installation, the guard post can be solid concrete 9 inches in diameter.

3. At least 24 inches of the guard post shall be embedded in the base, with at least 42 inches of the post above final grade.

4. In this installation, at least 26 inches of the guard post shall be embedded in the base, with at least

42 inches of the post above final grade.

5. Additional guard posts are required if the centerline spacing between guard posts exceeds 36 inches.

The additional guard posts are typically evenly spaced between the outer two posts.
