Notice ofIncident and Request for Assurance of Compliance for WNP-2 Discharge Incident
Dear Mr. Boynton:
During its special meeting ofJune 25, 1998, the Council authorized the issuance ofthe enclosed Notice of Incident and Request for Assurance ofCompliance (NOI) in response to an apparent violation ofthe WNP-2 National Pollutant Discharge Elimination System (NPDES) permit. On June 17, 1998, potentially contaminated water was discharged to the Storm Drain Pond, permitted as discharge point Outfall 002. The NPDES permit does not authorize radioactive discharges to Outfall 002. The NOI was issued pursuant to the enforcement authority ofthe Council under the Revised Code ofWashington (RCW) Chapter 80.50 and the Washington Administrative Code (WAC) Chapters 463-38 and 463-54. The Council's rules specify a thirty-day response period to the NOI to allow the Supply System to review the incident in more detail and provide additional information on the cause ofthe incident and, most importantly, to present assurances that appropriate measures are in place to prevent a recurrence. The Council, in cooperation with the state Departments ofHealth and Ecology, willreview the information provided by the Supply System in the assurance ofcompliance and incident report and willdetermine iffurther action is necessary. Ifyou have any questions, please contact Mike Mills, Council staff, at (360) 956-2151. Sincerely, Allen J. Fiksdal EFSEC Manager i/, AJF/MM/jk Q-L4-22 Enclosure 9807280334 980629 PDR 'ADQCK 05000397 8 PDR (360) 956-2000 Telefax (360) 956-2158 TDD (360) 956-2218
I l
BE<FORE< THE< STATE< OI< WASHINGTON ENERGY FACILITYSITE EVALUATIONCOUNCIL In the Matter ofCompliance by the Washington Public Power Supply System Nuclear Project No. 2 (WNP-2) with the Site 'ertification Agreement and National Pollutant Discharge Elimination System Permit NOTICE OF INCIDENT and REQUEST FOR ASSURANCE< OF COMPLIANCE I. Allegations Allen J. Fiksdal alleges as follows: 1. He is the Energy Facility Site Evaluation Council (Council) manager. 2.. The Washington Public.Power Supply System (Supply System) Nuclear Project No. 2 (WNP-2) holds National Pollutant Discharge Elimination System (NPDES) Permit No. WA-002515-1, issued by the Council, and has held this permit at all times material hereto. 3. On Wednesday, June 17, 1998, WNP-2 discharged approximately 16,200 gallons ofwater into Outfall 002. This discharge may have contained radioactive material. Outfall 002 - the Storm Drain Pond - is an approved discharge point for wastewater under the plant's NPDES permit. The permit does not authorize radioactive discharges to Outfall 002, with the specific exception oftritium. 4. This discharge occurred in response to a break in a fire main that released at least 125,000 gallons ofwater into a stairwell and into a portion ofthe basement ofthe Reactor Building. The water in the basement was potentially contaminated apd pumped into a collection area for subsequent processing. The water in the stairwell was sampled and showed no detectable activity over the Radiological Environmental Monitoring Program Lower LimitsofDetection (REMP LLDs). Based on this result, the Supply System began to pump water from the stairwell into Outfall 002. A sample was taken from the discharge hose while the discharge was in progress. This second sample showed the possibility ofCobalt 60 activity; Cobalt 60 is a radionuclide that should not be present in the fire protection system. Based on this result, the Supply System used good judgment and terminated the discharge to Outfall 002 immediately. Over the one hour twenty minute period ofdischarge, a small but unquantified amount ofCobalt 60 may have been discharged to Outfall 002. Q-active-projects-wnp.npdesnoi2.doc
I + r~ II. Notice ofIncident and Rcqucst for Assurance of Compliance I Based on the foregoing allegations and as provided by law, the Council hereby issues this Notice ofIncident and Request for Assurance ofCompliance, to be served on the Supply System.. 1. The authority for enforcement ofcompliance withNPDES permits and for the assessment of penalties is vested in the Council by RCW 80.50.040 and 80.50.150 and elaborated in WAC 463-54-070. 2. The above allegations give the Council probable cause to believe that a violation ofNPDES Permit No. WA-002515-1 may have occurred. First, the low level Cobalt 60 contamination observed in one ofthe stairwell grab samples indicates that Cobalt 60 was discharged to the storm drain; this is the basis ofthe Council's notice. The permit does not authorize radioactive discharges to Outfall 002. Second, Section S1.F contemplates the discharge ofwater from routine operation and testing ofthe fire protection system to Outfall 002. This was not a situation ofroutine operation and testing. 3. Because the Council is unaware ofany substantial danger caused to.humans or the environment and because the Supply System acted promptly with regard to release to the environment, the Council willnot assess a penalty for the alleged violation at this time. The Supply System's actions in conducting repeated samplings and analyses ofstairwell water to verify the water was below REMP LLDs demonstrated their intent not to discharge contaminated water to the storm drain. 4. The violation alleged in this notice could have affected public health, safety, welfare, and the environment. Questions remain regarding the Supply System's handling ofthe event. The Supply System shall, within 30 days ofthe date ofservice, provide the Council with (i) a detailed report ofthe incident, including a set ofdata showing discharge sample results, sediment analysis results, discharge volume, and results ofa recount ofthe second line-sample (the sample that showed Cobalt 60) to REMP LLDlevels. (ii) a table showing REMP LLDs for commonly expected activation and fission products; (iii) assurance that it complied with all terms ofNPDES Permit No. WA-002515-1, including a careful explanation ofwhy the Supply System believes there was no radioactive discharge to Outfall 002, in lightoftest results showing Cobalt 60 activity; and (iv) assurance that appropriate measures have been taken to preclude unauthorized discharges in the future, including assurance that Supply System staff understand the conditions ofthe NPDES permit.
