On April 8, 2016, a transformer failed in the 765 KV Switchyard at the Cook Nuc1ear Plant The transformer holding capacity is 30,119 gallons. As of April 15, approximately 17,000 gallons of oil had been recovered and or accounted for. Cleanup efforts are ongoing. At this time, free product has been collected and stored in temporary frac tanks on the site awaiting proper disposal. As of April 15, approximately 135 cubi.c yards of oil saturated soil has been removed from the spill vicinjty. Cleanup at the site continues.. No oil was discharged to the surface water. This spill does not pose a threat to the environment or public health or safety.

The transformer and the system in the vicinity was de-energized which allowed the recovery efforts to begin. Crews worked 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day for the first three days containing the spill until all free. product was recovered. Ongoing excavation of contaminated soils continues. The remaining oil in the failed transformer will be pumped out and properly disposed of once it is safe to proceed. We will provide notification to your office when cleanup efforts have been completed.

The cause of the oil release from the containment system was caused by a failure of a seal between the composite wall of the containment and the concrete firewall foundation.. This is the only composite type containment on the site; other containments are concrete and steel construction. The system transformers will not be energl.zed until we complete an analysis of this containment structure.
