| The licensee notified the National Response Center and the State Department  |
| of Environmental Protection (DEP) that approximately 5 gallons of a mixture  |
| of sulfuric acid and sodium hydroxide spilled from a tank truck onto the     |
| ground after a chemical reaction took place.  The spill was contained within |
| a portable dike area onsite and is being cleaned up.                         |
|                                                                              |

| The licensee is retracting this report based on the following:               |
|                                                                              |
| "This is a retraction of the notification made on 04/20/00 at 2029 hours     |
| (Event 36911).  This event was reported as a notification of another         |
| government agency [National Response Center and Pennsylvania Department of   |
| Environmental Protection (PADEP)] pursuant to 10CFR50.72(2)(b)(vi).          |
|                                                                              |
| "On April 20, 2000 at 1930 hours while Limerick Unit 1 was shutdown for      |
| refueling, 5 to 10 gallons of a dilute and partially neutralized acid        |
| (Sulfuric Acid-pH 3) was expelled from a temporary trailer tank onto asphalt |
| and stone surface in an adjacent area outside a temporary dike.  In          |
| addition, approximately 30 gallons of the acid/sludge mixture spilled into   |
| the temporary dike.  The spill never threatened navigable waterways, and     |
| subsequently was cleaned up within a 24 hour period.  The initial            |
| notification was conservatively reported based on information known at the   |
| time of the event.                                                           |

| "A minor spill of this nature is not reportable to the PADEP in accordance   |
| with 40CFR112 and the Preparedness Prevention Plan for Limerick Generating   |
| Station.  This spill from a temporary tank had no impact on navigable        |
| waterways and was less than the Reportable Quantity (69 gallons)."           |

| On Tuesday April 25, 2000, the customer was performing receiving inspection  |
| and noticed that the set pressure information on the Code Plates and the     |
| Name Plates do not conform to the specification requirements or the history  |
| docket testing information. The customer called the Quality Assurance        |
| Department of Dresser Valve Division to discuss the finding.  It appears     |
| that the set pressure information on the plates has been interchanged.       |
|                                                                              |

| We have conducted a full review of our records and confirmed that these are  |
| the only valves involved.  A full review of our procedures regarding plate   |
| preparation, inspection and installation will be completed.  Corrective      |
| actions will be initiated to address the internal issues, if warranted, and  |
| details will be provided in our closure reports at the completion of our     |
| investigation into the cause of this situation.                              |

| At 1342 CDT on 04/26/00, the Auxiliary Building Special Ventilation and      |
| Control Room Post Accident Recirculation Systems actuated due to a steam     |
| exclusion signal.   Auxiliary Building Special Ventilation and Control Room  |
| Post Accident Recirculation are Engineered Safety Features Systems.  The     |
| steam exclusion signal was due to the rupture disk on Boric Acid Recovery    |
| System rupturing.  Steam to the Boric Acid Recovery System was isolated.  At |
| 1425 CDT, steam exclusion was reset and the Auxiliary Building Special       |
| Ventilation and Control Room Post Accident Recirculation Systems were        |
| shutdown.  All equipment operated as designed.  There was no radiological    |
| release.  The licensee is currently investigating why the rupture disc       |
| ruptured.  Nobody was injured.                                               |
