MEMORANDUM
TO Trevor Clements
FROM . Doug Finan !7)-
SUBJECT: WLA for E.I. DuPont De Nemours & Company, Inc.
Please find attached a request by Dupont to increase the flow on pipe
#001. Because the facility has production based limits, the total pounds
of BOD should not increase. However, please review the WLA for this facility
to confirm that problems should not arise from this change.

Dear Mr. Finan:
Thank you for your letter of December 10. I apologize for
making an inappropriate assumption that you had detailed data on our
biofacilities at your fingertips. As we discussed by telephone
yesterday, the data you requested are given below:
Aeration Basin Effective Volume - 440,000 gallons
Clarifier Effective Surface Area - 1590 ft.2
Fayetteville Flow.,
Million gal. GLUMRB Standard*

Clarifier
Overflow (gpd/ft.2) 314 692 700
* Great Lakes - Upper Mississippi River Board of State Sanitary
Engineers, Recommended Standards for Sewage Works, 1971. The values
reported above are for plants in the flow range of 0.5 million gpd
to 1.5 million gpd.

There's a world of things we're doing something about

�•q _ ter': .�
r DOUGLAS S. FINAN -2- DECEMBER 18, 1984
The recommended standards are based on peak flow (for
"significant flow periods", i -.e. maximum daily) rather than average
values. Maximum daily flow is a more appropriate design parameter
than average flow.
We still maintain that flow limits are unnecessary for an
effluent limited discharge because exceeding the hydraulic or
oxidative capacity of the plant will result in exceeding the
mass -based discharge limits. However if the Department feels a flow
limitation is required, only a daily maximum value, rather than daily
average value, need be imposed to.conform to recommended standard
practice.
If you need any further information or clarification on this
subject, please contact me.
Sincerely,
Thomas W. Olcott
