Description:

Turbine Sump Outfall No: OOF (Internal)

Oil Separator & Volume Reduction System Parameter Code No: 00556 (Oil & Grease}

1. Date and Duration of Incident:

On May 14, 1998 at approximately 8:15 a.m. samples were taken from the Turbine Sump Tank (T-41} effluent during routine monitoring. Following such time, the results indicated a level of 37.5 and 37.0 ppm Oil and Grease (O&G) prior to discharging at Outfall OOF to the mixing basin. A second sample was collected and analyzed at approximately 4:15 p.m.

when the ongoing investigation of the system showed no visible signs of abnormal conditions. Visual observations showed no signs of unusual sheen or film through out the system. The results of the second analysis indicated 23.0 ppm O&G. A third sample was taken at approximately 9:40 p.m. at T-41 effluent and then also at Outfall 001. Samples were then sent to the Company laboratory for analysis. The results of the-third set of samples showed T-41 effluent to be 9.0 ppm O&G.

Results of Outfall 001 discharge O&G was nondetect, below MDL of 0.2 ppm.

2. Identification of Specific Effluent Limitation or Monitoring Requirement Affected:

Exceeded daily maximum limit of 20 ppm O&G at internal Outfall OOF.

3. Description* of Incident:

Results of samples of T-41 effluent indicated a higher value than the permitted limit of O&G at Outfall OOF. Upon knowledge of results, Plant personnel began investigating the systems upstream of the T-41 tank. Those systems included the Turbine Sump oil separator (M-18) and the Turbine Building sump. No unusual conditions or events were discovered through out either systems. Precautionary measures were* initiated.

Oil absorbants were installed within the T-41 tank and Turbine Sump. A contractor was called onsite to clean M-18 as soon as possible. M-18 and T-41 were cleaned on 5/15.

4. Apparent Cause:

Upon further investigation, it was discovered that a contractor was working on the Plant Turbine on 5/14 where a degreaser was used. The contractor inadvertently dumped some

used degr~r down the Plant floor drains~ading to the Turbine Building Sump resulting in a increase of oil and grease in the Turbine Sump effluent. The contractor provided the Plant with a Material Safety Data Sheet on the degreaser (OE/CL-100 produced by Hillard Industries) where appropriate disposal practices were determined.

5. If not immediately corrected, the anticipated time the condition is expected to continue: '

Once the contractor ceased occasional degreasing on 5/14, the effluent eventually returned to normal.

6. Corrective Action - The following corrective action was taken or will be taken to reduce, eliminate and prevent reoccurrence:

Contractors working onsite were again advised not to discharge any products, by-products or substances down Plant floor drains without Plant authorization. Floor drains are currently being labeled and marked for reminders. The degreasing agent will be collected in 55 gallon drums and disposed of offsite according to liquid waste handling and disposal regulations. M-18 and T-41 were emptied and cleaned accordingly. Oil absorbants were placed at M-18 and T-41 for precautionary measures.

7. Additional Comments:

The T-41 effluent returned to normal within 11 hours1.273148e-4 days <br />0.00306 hours <br />1.818783e-5 weeks <br />4.1855e-6 months <br /> upon knowledge of the incident.

The flow of T-41 effluent was .006 MGD at Outfall OOF on 5/14.

It combined with approximately 10.18 MGD flow of the mixing basin eventually discharging to Outfall 001. Outfall 001 O&G concentrations were nondetect.

Outfall observations at internal Outfall OOF, the mixing basin, and external Outfall 001 to Lake Michigan were occasionally performed on 5/14 and 5/15. No unusual sheen or film was observed during the incident.

Attached are analytical results from* the third final set of O&G samples taken at T-41 effluent and Outfall 001.
