Corrective Action Taken:
|
Stormwater pond pump was shut off and discharge stopped. City is requiring Global Company to pump out stormwater ponds and not discharge any water currently held in ponds to the stormwater outfall. Will be following up to understand what happened that diverted this chemical into the stormwater pond instead of the holding tank as designed. Downstream access areas have been posted and the public beach is closed.

Description Of Incident:
|
Water Resources received report of "foaming" manhole at approximately 1:30 on 6/9/2016. Dispatch to field crew issued at 2 pm. Staff onsite at 2:30, discharge stopped at 2:50 upon notification of Global Company's (oil tank farm) staff who stopped the stormwater pond pumps. Current understanding is that a test of the fire suppression system occurred on 6/8 - foam was supposed to discharge to a containment system but some was released to the on site stormwater pond which is a pumped system to provide additional containment. Pumping of the pond is believed to have possibly started around 10 am on 6/9. It is unknown at this time how much of the "Ansul Fluoroprotein 3%" entered their onsite stormwater system and then was discharged to the stormwater outfall. Foam was apparent in the stream at 2:50, but was not visible by 4 pm when staff returned. Risk to human health/environment has not been determined, though anticipated to be small due to dilution. State department of health was consulted but does not have thresholds for the constituents in the foam (polyethylene glycol, cumene sulfonate, calcium chloride and zinc chloride).
