SUBJECT: Revised Wasteload Allocation For Town Of Kenansville
Per your request, I am providing you with the results of the
preliminary stream impact analyses for an expansion of the Kenansville
facility from 0.17 to 0.25 MGD_ Please remember that these limits are
speculative and cannot be considered as a final wasteload allocation.
If Kenansville wishes to modify their permit for an expansion to 0.25
MGD, they should submit a formal NPDES permit application.
The speculated limits are as follows:
BODS
NH3

TSS

SUBJECT: Kenansville 201 Facility Plan
Wasteload Allocation
Project No. C370591-01
The amendment to the Kenansville 201 Facilities Plan may consider
an expansion of the existing wastewater facilities from the current
0.170 mgd to 0.250 mgd. Therefore, it is requested that a wasteload
allocation for discharge into Grove Creek at the present location be
developed for a flow of 0.250 mgd. The current limits are BOD5 28/20
winter/summer, NH3 13/5 winter/summer and TSS 30.
Enclosed please find a map depicting the present discharge point
on Grove Creek. Although it is not topographic, I hope it is adequate
for the development of the requested wasteload allocation.
If you have any questions or need additional information please
contact me at 3-6900.
