e.
Volume of Wastewater to be permitted: It is recommended
that no limit be placed on flow.
What is the current permitted flow limit? There is no
current limit on flow.
Actual treatment capacity of the current facility :
The holding pond has a capacity above the pond operating
level of 89,253 cubic feet, which is equal to the
theoretical site runoff volume resulting from a ten year
storm event of 45 minutes duration.
Date and construction activities allowed by previous
Authorizations to Construct issued in the previous two
years: none
Please provide a description of existing or substantially
constructed wastewater treatment facilities:
The facility consists of a holding pond which collects
runoff from five timber storage areas. Water is recycled
back to irrigate the timber. When the pond level gets
low, water is pumped in from an on -site well. When the
pond is at operating level, discharge occurs only
following the equivalent of a 10 year storm event of 45
minutes or longer duration. Discharge is by gravity flow
over a weir which is screened with a 1 inch bar screen.
The total site area is 18.2 acres, and approximately 8.6
acres are disturbed.
f. Please provide a description of proposed wastewater
treatment facilities: There are no current plans to
upgrade the existing facility.
g. Possible toxic impacts to surface waters: none known
h. Pretreatment Program: Not a POTW .
Residuals handling and utilization/disposal scheme:
Holding pond residuals consist of bark and other organic
debris carried in runoff from the storage areas and are
disposed of on site.
Treatment plant classification Class I facility
SIC Code 2411
Wastewater Code Primary 19 Secondary N/A
Main Treatment Unit Code : 500X0

PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant
Funds or are any public monies involved? No
2. Special monitoring or limitations requests: none
3. Important SOC, JOC or Compliance Schedule dates:
Date: N/A
Submission of Plans and Specifications: N/A
Begin Construction: N/A
Complete Construction: N/A
4. Alternative Analysis Evaluation:
International Paper Company has not evaluated disposal
alternatives. The Region has considered the quality and
frequency of discharge at this facility and believes that
reissuance of the NPDES permit is the most practicable and
environmentally -sound alternative at this time.
PART IV - EVALUATION AND RECOMMENDATIONS
The facility appears to be well -operated and maintained.
There has been only one discharge reported in the last twelve
months and no apparent compliance problems.
It is recommended that a draft permit be prepared and placed
at public notice. If no significant adverse public comment is
received, it is recommended NPDES Permit No. NC0074691 be
reissued to International Paper Company in accordance with the
basin -wide permitting strategy.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
IP/Chadboum has a log wetting operation that discharges to a large holding pond. Water is
recycled for the log wetting. Discharge occurs in response to storm events- but the discharged
water is considered process water. Discharge has occurred only 7 times in the past 3 years. IP has
recorded "less than" values for settleable solids. Turbidity values are well under 50 NTU. 40CFR
429 Subpart I specifies pH and no debris -this will be recommended for the renewal.
TSB still recommends weekly sampling as specified in previous permit, since the discharge event
may occur at any time and not just once per quarter.

G. The holding pond is designed to hold the make-up water for
the sprinkler system, to receive and.stormwater, to provide
silt control for the drainage system, and provide overflow
control for intense stormwater events.
Stormwater is to be stored in the pond above the operational
level.of the sprinkler system to the elevation of the over-
flow weir.' The pond has a storage capacity of 89,250 CF
which is approximately a 107year—storm_event of 45-minute
duration. Any additional stormwater is routed over the 20-
foot weir. The drainage design calculations detail both the
weir design and overflow rates. The pond overflow will dis-
charge to a man-made canal which flows to a prong of Dunn
Swamp.
Solids will be contained from going over the weir by a
1-inch screen across the weir face. The pond will provide
silt storage at the bottom, although this will require peri-
odic maintenance. The pond slopes and site perimeter areas
will be grassed per the requirements shown on Plan Sheet No.
