Dear Sirs:
In accordance with the instruction in the Authorization
to Construct issued by R. Paul Wilms on 3/28/88 (attached), I
have enclosed the engineering certification attesting that the
construction of the wastewater treatment modification at
Fayetteville Works of E.I. du Pont de Nemours & Co., Inc. in
Bladen County, Permit No. NC003573, was completed in accordance
with approved plans and specifications by the Division.
At the present time, the new aeration tank is operating
under test procedures with the former aeration basin as an
operational standby (i.e. available for aeration service in case
of problems with the new tank system.) Barring problems, this
test status will continue until the end of January, when the
basin will be converted to a sludge digester.
Sincerely,
Thomas W. Olcott
