Dear Mr. Seagle:
December 7, 1987
R. Paul Wilms
Director
Per your request, October 22, 1987, the Technical Support Unit of the
Division of Environmental Management has completed preliminary stream impact
analyses for the proposed discharge(s) using a routine Level "B" model. The
results of these analyses are attached for your review. As stated, these
results are preliminary and should not be considered as a final wasteload
allocation. Final wasteload allocations will only be developed after an
official NPDES permit application has been submitted along with the required
application fee.
Should you have questions or comments regarding this matter, please
feel free to give me a call at 919-733-5083.
