| Pipe RUptUre Follow-up Report.Mr. Harper: Pursuant to 25 Pa. Code § 91.33 and § 91.34, this is to provide a written description of an event involving a ruptured discharge pipe. first reported to Ms. Kareen Milcic, Pennsylvania Department of Environmental Protection (PADEP), via telephone at approximately 2:00 PM on June 11, 2007.A corrugated pipe ruptured that channels water discharged from our Unit 2 Emergency Outfall Structure (EOF), NPDES Permit No. PA0025615 Outfall 010, into an Impact Basin to reduce velocity and prevent erosion. That rupture caused the discharging water to create a sinkhole, washing out soil and fill material that slid down the hill towards the Ohio River. Most of the washed-out material appears to have been captured on a flat area between the outfall and the river, and in the Impact Basin itself.. Some material may have made it past the Impact Basin to the river. Note that the materials washed out were sandy and rocky, typical of the fill used during construction of BVPS.BVPS utilizes two containment booms at Outfalls 001 and 010 as a Best Management Practice (BMP) to prevent solids, foam, scum, etc.-from entering the river channel. There was no evidence observed of solids, mud, or other signs of eroded materials reaching the river channel beyond the area of the outfalls. | | * FENOCRoute FE NOCBeaver Valley Power Station 168 P.O. Box 4 |
| In response, BVPS has undertaken the following BMP actions until permanent repairs are made:* Flow from the outfall was reduced from the typical 2,500 -4,000 gallons per minute to 200 -300 gallons per minute.' Note that We cannot reduce flow any lower becauise that is the minimum amount of cooling water heeded fot several nuclear safety systems' E'en if the Unit 2 plant were shutdoWn, that Witter would be needed to ensure decay heat removal from the nuclear reactoi.* Temporary pumps and hos'es wer'e installed in the EOF to rouite the water to the'river (in place of the damaged piping).

Mr. Harper:
Pursuant to 25 Pa. Code § 91.33 and § 91.34, this is to provide a written description of an event involving a ruptured discharge pipe.first reported to Ms. Kareen Milcic, Pennsylvania Department of Environmental Protection (PADEP), via telephone at approximately 2:00 PM on June 11, 2007.
A corrugated pipe ruptured that channels water discharged from our Unit 2 Emergency Outfall Structure (EOF), NPDES Permit No. PA0025615 Outfall 010, into an Impact Basin to reduce velocity and prevent erosion. That rupture caused the discharging water to create a sinkhole, washing out soil and fill material that slid down the hill towards the Ohio River. Most of the washed-out material appears to have been captured on a flat area between the outfall and the river, and in the Impact Basin itself.. Some material may have made it past the Impact Basin to the river. Note that the materials washed out were sandy and rocky, typical of the fill used during construction of BVPS.
BVPS utilizes two containment booms at Outfalls 001 and 010 as a Best Management Practice (BMP) to prevent solids, foam, scum, etc.-from entering the river channel. There was no evidence observed of solids, mud, or other signs of eroded materials reaching the river channel beyond the area of the outfalls. In response, BVPS has undertaken the following BMP actions until permanent repairs are made:
- Flow from the outfall was reduced from the typical 2,500 - 4,000 gallons per minute to 200 - 300 gallons per minute.' Note that We cannot reduce flow any lower becauise that is the minimum amount of cooling water heeded fot several nuclear safety systems' E'en if the Unit 2 plant were shutdoWn, that Witter would be needed to ensure decay heat removal from the nuclear reactoi.
- Temporary pumps and hos'es wer'e installed in the EOF to rouite the water to the'river (in place of the damaged piping). The hoses were positioned in such a way to prevent erosion.
p 'Further BMPs will be implemented as identified.
- Work has commenced to permanently repair or replace the piping.
