Apparent Cause:
There were two incidents earlier in May when excessive oil and grease were found in T-41.

Corrective Action - The following corrective action was taken or will be taken to reduce, eliminate and prevent recurrence:
As previously explained in the May 28, 1986 report, the oil / water separator M-18 was cleaned by A&B Industrial Co. on 5/24/86. Accumulated oil and grease were removed from the separator components to improve its efficiency.
As previously explained in the May 21, 1986 report the oil / water separator was returned to service and arrangements made to better coordinate bypassing of the system for maintenance or repairs.

A visual check of the mixing basin discharge during both events showed no visible oil in the discharge or lake.
