The facility is going to be discharging non -contact cooling water into a drainage ditch which
travels a very long distance until it reaches the tributary of Bachelor's creek. It should not
cause any impact to the area. The permittee may want to provide a shielded outfall to
prevent excessive erosion and turbidity issues. Prior to the use of any chemicals or biocides,
the permittee must submit a completed Biocide 101 form and the manufacturers' information
for review.
It is recommended a permit be issued to the INGENCO Wholesale Power, LLC in
accordance with the Neuse river basinwide plan.

ALTERNATIVES ANALYSIS
General
The discharge to be permitted is the non -contact cooling tower blow down water. The
two cooling towers are the facility will discharge at a rate of approximately two gallons
per minute for a combined daily volume of about 5760 gallons per day. No cooling
tower treatment chemicals (anti-scalants, biocides, etc) will be used. The site for the
project is located on the Central Regional Solid Waste Management Authority landfill
site and will use existing drainage features to convey the wastewater to Bachelors Creek.
The existing soils on the site include Ra — Rains fine sandy loam and GoA — Goldsboro
loamy fine sand. Both of these soils have severe wetness conditions and a high water
table.
1. Connection to Municipal or Regional Sewer Collection System
The project site is located on the property of the Craven County Landfill in western
Craven County. There are no existing or planned sewer collection systems within a 5
mile radius of the project site. The unavailability of an existing or planned system
discounts this alternative.
2. Subsurface Disposal
Infiltration systems were evaluated as an alternative but due to soil characteristics
including severe wetness and a seasonal high water table between 1.5 and 5' below
the surface, this was not considered a reasonable alternative. There is a small area on
the landfill site currently used for on -site septic systems. This area is not large
enough for this volume of disposal and would not allow any future expansion on the
landfill site. The only alternative would be to find an offsite area and construct an
infiltration system.
3. Spray Irrigation
The adjacent landowners have been contacted about spray irrigation to be used on
crops and due to the type of crop (mostly pine trees), the amount of discharge, soil
type and the depth of the seasonal high water table, spray irrigation does not appear to
be a viable option for the immediate adjacent areas. The closest area for possible
spray irrigation disposal appears to be a farm approximately 1.5 miles away.
However using exiting roadways and easements the distance is approximately 3.5
miles.
4. Wastewater Reuse
Wastewater flow off -site will be minimized by installation of a 4,000 gallon tank
located and maintained on site. Accumulated wastewater will be used by Landfill
personnel for dust control when practicable and consistent with needs of the landfill.
Excess wastewater will be discharged off -site.
