Section 1: Specifications and Requirements

A. General

These specifications and requirements for South Carolina Electric & Gas Company and the Developer, which are general in nature, cover the material, construction, workmanship and procedures for the typical installation of underground electrical facilities to new commercial projects. The method of feed shall be at the discretion of South Carolina Electric & Gas Company. The developer/owner should contact the Company as soon possible in the planning stage of the project to address electrical service issues such as voltage, service point, etc.

B. Definition of Terms

1) The term “Company” when used herein means South Carolina Electric & GasCompany.

2) The term “Developer” when used herein means the party entering into theagreement with the Company.

3) “Radial service” shall mean a cable connected to an overhead line (or other sourceof electrical energy) extending down the pole and under the ground to one or moretransformers together with the necessary accessories to assure proper operation.

4) “Loop service” shall mean a cable extending from an overhead line down the pole(or other source of electrical energy) under the ground to a transformer, extended(or looped) to additional transformers one at a time, then extended to and upanother pole to an overhead line. Such service may have a normally open point,as Company may deem appropriate.

5) “Underground secondary service” shall mean secondary service wires furnished,installed, owned and maintained by the customer which run from transformer(overhead or pad-mount) or other point of service (i.e.; hand-hole, Company ownedpole, Customer owned pole, etc) identified by Company to customer’s load center.

6) “Foreign Utility” shall mean any electric, gas, communication, water, sewer,drainage or other utility not owned by SCE&G Co.

C. Company and Developer’s Responsibilities Defined

1) In order to receive electric service, the Developer shall:

a) Furnish (at no cost to the Company) an acceptable drawing or plat (electronicformat is standard) showing details of property lines, buildings, dedicatedeasements, sediment and erosion control measures, water lines, sewage,drainage, any other underground facilities and a grading plan showing initial andfinal contours. Environmentally sensitive areas must be shown on proposedlayouts (wetlands, bodies of water, cemeteries, historical sites, etc.)

b) Coordinate the approval of governmental agencies required for the development(i.e.; buffer zones, wetlands, zoning, land disturbance, etc.)

c) Provide suitable easements for electrical service including restrictions for theelimination of encroachments, which may interfere with the continued operationand maintenance of the underground electric facilities.

d) Specify the length of time anticipated for the completion of the project (includingeach stage or phase of development when known) and provide the date’stemporary and permanent electric service is required. Coordinate major schedulechanges with the Company. Furnish technical details of electrical service needsincluding voltages, size and type of connected loads and similar data.

e) Install and maintain permanent property corners prior to the start of work by theCompany.

f) Initiate stabilization measures as required both before and after installation ofunderground lines and include this activity in sequencing of construction activitiesin the Storm Water Pollution Prevention Plan. Developer will be responsible fortemporary stabilization, if necessary, once final grade is established and prior toCompany trenching activities. Do not initiate final stabilization on easement priorto Company installing underground lines. Any inlet protection will be responsibilityof the developer.

g) Establish final grade and tamp any required filling or grading before the start of anyunderground distribution construction. Costs incurred due to changes in earthgrades after the start of construction will be borne by the Developer.

h) Furnish, install, own and maintain the concrete transformer pad and vehicular

protection bollards, if required. Furnish and install all necessary conduits, pull wire, pull boxes, bends, including necessary trenching and back filling, in accordance with Company drawings and specifications, from the transformer location to the source. This shall include galvanized bends, transformer entrance conduit and the first section of PVC SCH40 conduit up the pole. Installation by the Developer shall comply with Company drawing 06.04-08 and be subject to Company acceptance.

i) Furnish, install, own, and maintain the meter base for services served by atransformer capacity of 150 KVA or less. Transformer capacity will be based onexpected load rather than main disconnect size. Services larger than those listedabove will generally be metered using current transformers. Note – This is ageneral guideline only; Company Metering Department should be consulted toconfirm proper equipment needed for each situation. These guidelines are subjectto change as metering technology changes.

j) Keep the transformer and primary cable unencumbered and accessible formaintenance and provide suitable vehicular barriers where required per Companydrawing 17.02-01D.

k) Notify Palmetto Utility Protection Service (811) for marking of underground facilitiesprior to digging. Hand dig foreign utility trenches in areas crossing electrical cablesalready in place to eliminate contact with electrical cables.

l) Furnish and install secondary conduit and conductors, including connectors forconnection at service point. Required service conductor sizes are 1/0 through 750KCMIL stranded copper or 1/0 through 750 KCMIL stranded aluminum cables ormultiple conductors of these sizes. Connectors for use in pad mount transformersshall be 2-hole compression, lug type, as specified on drawings 14.02-03A, 14.02-03B and 14.02-03C.

m) Take service at the service point identified by the Company. For pad mounttransformers, the number of secondary service connections is limited to themaximum as shown on the tables in drawing 17.02-01C. Secondary servicecables shall comply with the National Electrical Code, current edition, as aminimum when installed. Secondary cables carrying metered energy shall beinstalled in separate conduit or raceways from all other cables or wires.

n) Furnish, install, operate and maintain phase converters for three phase loads(where Developer has elected not to utilize single phase) in areas with only single

phase available. Developer can elect to pay a difference in cost and monthly operating fee for three phase service in lieu of installing phase converter.

o) The developer will be fully responsible for compliance with any tree or bufferordinances affecting SCE&G easements. Any funding or tree replacement will bethe responsibility of the developer. Buffer requirements are in addition to andseparate from SCE&G easements. The developer shall be fully aware of allappropriate ordinances that can affect SCE&G's right of way and should take thisinto account when assigning the easement.

p) The developer shall be fully responsible, as required by local ordinances, toestablish and maintain tree barricades around all trees required to be preserved.Any required barricades shall be in place prior to SCE&G beginning design orinstallation of underground facilities. The standard method of construction will beby an open-trench (trencher or back hoe). Any encroachments in barricaded areaswill require directional bores to protect trees and shall be considered as non-standard service to the developer and at the developer’s expense. The developershall be solely responsible and liable for any tree damages incurred during theinstallation of underground electric facilities that are caused by the developer’sfailure to properly barricade any significant trees, as prescribed by localordinances.

The developer will be responsible for coordination of the approval of governmental agencies required for the development (i.e.; buffer zones, wetlands, storm water permitting, zoning, etc.)

Wetlands

Provide official verification and confirmation of the wetlands and permits that have been issued, as stated in a letter from the U.S. Army Corps of Engineers (USACE). The letter must reference the detailed site plan drawing (same dated version) and include a file number. Stake or mark the wetlands boundaries prior to construction by SCE&G. If unable to provide the above information, SCE&G will provide a Wetlands Determination Authorization Form for developer to sign giving SCE&G permission to have the impacted property surveyed for jurisdictional wetlands, which could include the USACE entering the property. Any costs associated with survey and resulting delineation required will be at developer’s expense.

Storm Water

Obtain coverage under the NPDES General Permit for Storm Water Discharges from Construction Activities for all easements and areas of electric line construction and provide official verification of this coverage. Provide site maps showing the locations of all sediment and erosion control measures planned for electric line construction and include these areas in the Storm Water Pollution Prevention Plan.

Developer will be responsible for installation, maintenance, and inspection of all sediment and erosion control measures around electric lines. Notice of Termination will not be submitted by Developer prior to Company completing all electric line installation.

2) The Company shall:

a) Furnish, install, connect, own and maintain all required overhead facilities, primarycables, and the pad mount transformer. Metering facilities will be installed atlocations approved by the Company. Connecting these metering facilities shall behandled on an individual basis.

b) Prepare an electrical distribution layout for Developer’s approval prior toconstruction. The layout will be the Developer’s plat, drawing or other informationincluded in paragraph C 1 (a) above. If changes requested by the Developer afterapproval result in additional expenses, the Developer shall bear these additionalexpenses, including reimbursement to the Company for all changes.

c) Supply the Developer a copy of the approved print prior to beginning construction.

D. Reimbursement

The Developer may be required to pay the Company for the cost of facilities installed in excess of standard as determined by the Company. The Developer may also be required to pay a contribution in aid of construction for projects where the construction cost to expected revenue ratio is above a level set by the Company. This will be in addition to the charge for non-standard service. An estimate of the amount of such reimbursement will be made available to the customer upon request before work begins. All designs must be analyzed by Company engineers. The Developer will be required to reimburse the Company for all costs associated with all changes made at the Developer’s request to the electrical distribution layout after it is approved by the Developer and the Company.

Section 2: Underground Commercial Service

A) The standard method for providing commercial underground service will be from anoverhead transformer bank with an underground service (reference drawings 06.04-06 and 06.04-07. Underground secondary service will be furnished, installed, ownedand maintained by the customer.

B) The Company may elect to use underground primary and a pad mount transformerfor large loads or in all-underground areas. The maximum length of undergroundprimary from dip pole or switchgear to a pad mount transformer is 300 feet.

C) Requests for underground primary, pad mount transformers, loop feeds, or other non-standard service will be considered, but the customer will be expected to pay thedifference in cost in excess of standard service as well as a monthly operating fee forthese facilities.

D) The customer’s request for underground service is subject to Company review andapproval.

E) Some of these conditions may not apply to customers served from a network or totallyunderground system. These situations will be handled on an individual basis.

F) These conditions also may not apply when, in the opinion of the Company, theelectrical demand exceeds 2500 KVA or other conditions dictate the need for a specialdesign or substation. These situations will also be handled on an individual basis.

Section 3: Design Considerations

A) The transformer bank or dip pole shall normally be located on Developer’s property;the necessary feed to it will normally be overhead.

B) Truck access is required for all company facilities. Pad mount transformers will belocated such that a 10 foot wide corridor will exist for access by trucks for maintenanceof the transformer. A working area of 30 feet by 18 feet shall be available for use byheavy equipment when replacing the transformer. This area shall adjoin thetransformer and may include part of the truck access. An additional area 20 feet by10 feet wide parallel to and on one side of the work area shall be clear of obstructionsgreater than 8 feet in height. This additional area is to provide space for operatingtruck-mounted lifting equipment. Reference drawing 17.02-01D.

C) Connection of customer’s equipment ground to Company ground electrode intransformer will not be allowed and customer’s equipment grounding conductor shouldnot be brought out to transformer with service conductors. Equipment ground shallconform to NEC requirements.

D) The pad mount transformer shall be placed in such a location as to meet Company’spermanent clearance requirements of 4 feet from the side and rear and 12 feetclearance from the front. The front clearance may include required space for truckaccess. See Company’s Drawing 17.02-01D.

E) The distance from the transformer or cable location shall be 20 feet to any fuel storagetank (liquid or gas), fuel dispensing point, and/or customer owned generators.

Section 4: Construction Details and Coordination Installation of underground electric service facilities shall be performed in accordance with plans and specifications furnished by the Company. The following stipulations are made to clarify certain details of the trenching and backfilling agreements involving the Company and the Developer. 1) Foreign Utilities and Obstructions

Field determination of the locations and elevations of all foreign utilities and obstructions in areas of conflict with primary and secondary cables and transformer pads shall be performed by the Developer. The location of all crossing facilities shall be clearly marked by the Developer. See drawing 16.01-05.

2) Right-of-Way

Construction will not begin until satisfactory rights-of-way (including easements) are made available to Company. Developer is responsible for all stabilization requirements, sediment and erosion control measures, and clean up of debris from right-of-way clearing operations to include but not limited to limbs, trees and stumps. Company will utilize proper installation techniques, but is not responsible for damage to landscape, bodies of water, trees or flora during installation of facilities. Obstructions to the performance of Company work such as construction materials and equipment shall have been cleared away by the Developer prior to the start of Company construction.

3) Trench Excavation and Backfill

Trench excavation and backfill is the responsibility of the Developer. It is the Developer’s responsibility to ensure compliance with OSHA and other Federal, State and local requirements while doing this work. Backfill shall be dirt, sand, or soil excavated from the trench, or other suitable soils, free from rock, organic materials, construction materials or other debris.
