reflect 2008 average costs and are proposed to become effective May 4,2008.The cost materials
and labor has increased significantly over the past year,resulting in an overall increase in line
extension costs.
Enclosed as Attachment 1 is a copy of the workpapers supporting the line extension cost revisions
contained in the proposed tariff sheets.Please direct any questions to me at 509.495.8620.

SCHEDULE 51 -continued
51D
EXAMPLE:
For a single-phase primary overhead extension of 2310
feet:
1.The Basic Cost is calculated from the charges in
section 7.
a.$3,774 +($4.04 perft x 2310 ft.)=$13,106.
b.The average Basic Cost is $13,106/231 0 ft =
$5.67 per ft.
2.Exceptional Cost:
a.If the cost estimate from the extension drawing is
$14,000,the average estimated primary cost is
$14,000/2310 ft =$6.06 per ft.
b.The Exceptional Cost for a long extension is the
difference between the estimated cost and the
tariffed cost for the length greater than 1500 ft:
EC =($6.06 -$5.67)x (2310 ft -1500 ft)=$316.
3.Total Primary Cost
a.The Customer's primary extension cost is
$13,106 +$316 =$13,422.
b.The total extension cost is calculated by
combining all Basic Costs,Exceptional Costs,
Allowance,Cost Reductions and Share of
Previous Extension for the extension.
5)"Customer-Requested Cost"is the cost of unusual labor and/or
materials which is requested by the Customer but which is not
necessary to construct the Line Extension based on the
Company's minimum design,construction,and operating
practices.All Customer-Requested Costs must be paid in full
by the Customer.Customer-Requested Costs may include,
but are not limited to,the following:
a)facilities to provide three-phase service where single­
phase service is adequate
b)construction which is not for electric service
c)facilities longer,deeper,or larger than deemed
appropriate by the Company
d)underground facilities in overhead areas
e)soil compaction on private property

6)"Share of Previous Extension"applies only to Primary Circuits
less than five years old.If part of a previous line extension is
used to serve a new Customer,the new Customer must pay a
share of the previous Primary Circuit cost and Transformer
cost,if shared,to the Company before the start of
construction.The amount paid by the new Customer will be
refunded to existing Customers in relation to their share of the
Primary Circuit and Transformer,if shared.The Company will
refund appropriate shares to the bearers of Extension
Certificates when the Certificates are presented for payment
and the connection of the subsequent Customer has been
verified.The Company will make a reasonable attempt to
inform the bearer of the Certificate when a refund is due.
Bearers of Extension Certificates must apply for refunds
before the original line extension becomes six years old.
Unclaimed refunds will be returned to the contributor.
EXAMPLE:
1.First Customer pays $8,450 for 1,000 feet of
primary underground circuit ($8.45 per foot).
2.Second Customer takes service within five years
using 600 feet of the original extension.
3.Both Customers share the first 600 feet equally:
600 ft x $8.45/ft x }2 =$2,535.
4.The Second Customer's payment of $2,535 will be
refunded to the First Customer to reduce his
investment in the 600 feet to $2,535.The First
Customer's investment in the remaining 400 feet
remains at $3,380.($8,450 -$2,535-$2,535=$3,380)
EXCEPTION:If the refund to an existing Customer is
less than $50 each,the new Customer will not be
required to pay that share and the existing Customer
will not receive a refund.
