Present-Value-of-Costs Analysis
Discharge to existing tributary to South Fork Crooked Creek(Zero 7Q10 flow)
Capital Costs
o Land acquisition costs $NA
o Equipment costs $NA
o Labor costs $Included with installation costs
o Installation costs $23,000
o Design costs $ 3,200
Co = $26,200
Recurring Costs

Ct = $32,730
Present Value of Costs Calculation
Present value standard formula:
n Ct
PV = Co+
t=1 (1+ r)1
Where:
PV= Present value of costs.
Co=Costs incurred in the present year.
Ct= Costs incurred in time 1.
t=Time period after the present year(The present year is t= 0)
n = Ending year of the life of the facility.
r= Discount rate. For these calculations,the applicant shall use an interest rate quoted by the
lending institution. The loan interest rate quote shall be provided with this analysis.
However, if costs are the same in every time period from year one through year n (i.e., Ct= C, a
constant for t= 1,2,..., n), then the formula reduces to:
PV = Co+ C C 0 +00_ 1
r(1 +r)"
Co = $26,200
C = $32,730
r = 4.875 % (Rate provide by Bob Sledge of NCDENR on May 18, 2009))
n = 20 years
PV= $409,331 (assuming equal yearly costs)

Subject: Radiator Specialties Materials Testing
Rick,
Thank you for the opportunity to provide you with this "place holder" budget number for materials testing
services.
Based on our conversations, it is our understanding that the project is the installation of approximately 2000
linear feet of 4 gravity drain line. Our services will include testing of sand backfill around the pipe and soils
above the sand to grade. It is anticipated that the project will span a 1 to 2 week period.
For the proposal,we have assumed 10 trips to the project site at 3-4 hours per trip. I have included two
proctors (one sand and one soil) and engineering oversight in preparing a summary letter of test results. With
these assumptions, we suggest a project budget of$2600.
Once the details of the project have been defined and a contractor schedule has been developed,we will be
able to provide a more formal proposal for the requested testing services.
Thank you for your consideration,
JOHN H. Ross, P.E.
