| Title | Offsite Notifications Made Due to Spill of Approximately 1400 Pounds of Sulfuric Acid |
| Event Description | On 12/17/2004 at approximately 10:53 MST, Palo Verde Nuclear Generating Station (PVNGS) notified the Department of Transportation/US. Coast Guard National Response Center of a sulfuric acid spill to the ground at the Water Reclamation Facility. The source of cooling water for PVNGS is treated sewage effluent. The effluent is conveyed to the site through approximately 35 miles of pipeline, and treated in the onsite water reclamation facility to meet plant water quality requirements. The acid spill has no impact to the radiological health and safety of the workers or the public.
The spill is estimated at 1400 pounds. The reportable quantity is 1000 pounds. The sulfuric acid is classified as a CERCLA Hazardous Substance and EPCRA Extremely Hazardous Substance. The release has been isolated and the apparent cause is a leak in an underground section of pipe. There were no injuries and no known or anticipated acute or chronic health risks. The National Response Center report number is 744571. The Arizona Department of Environmental Quality was also informed at 10:51 MST. There was no impact to the three generating units from the spill at the Water Reclamation Facility which is located at a separate part of the Owner Controller Area. All 3 PVNGS Units are operating at approximately 100% in Mode 1. The NRC Resident has been notified of the event and this notification. |
