Subject: haste Load Allocation.
City of Raleigh
Neuse River Wastewater. Treatment. Plant
Wake County
Dear Mr. Butler:
Mr. -Gordon Ruggles of Hazen and Sawyer Engineers asked that I write you
regarding; the waste load for the expanded."flow at the Meuse River:Plant after
1985. As you will recall, 1985 is the end of the Corps -of Engineers'
present commitment for augmenting low river flows.
Discussions by members of our Technical Services with Mr. Joe Lewis of
the Corps have. determined that the Corps does not plan to make any decision
on future flow augmentation until 1984 or 1985: They must maintain. at least
the 7 day 10 year low flow but flow augmentation above the 7Q10 for the time
after 1985 is not certain at this time. Based upon a 7Q10 low flow the
waste load allocation. for Raleigh would be the same as those limits calculated
for the plant prior to the Falls completion and augmenting of low flows. (See
attached copies). Those limits wouldbe the most stringent for the period
after 1985 assuming the forps made no augmentation above the 7Q10 level. Any
augmentation above the 7Q10 level will result in effluent limits being less,
stringent depending on the amount to which the Corps finally commits.
If you have any questions concerning this matter, please contact
Mr. Randy Williams, Supervisor, Modeling Unit, 733-2930 or me at 733-5181.
Sincerely,
William C. Mills, Supervisor
