During the inspection, it was discovered that one of the UV module’s bulbs exceeded the manufacture’s recommended hours, 12,000 run hours, by 471 hours. According to the Standard Provision I.D, “The Discharger shall, at all times, properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the Discharger to achieve compliance with the conditions of this Order.” According to the Discharger, it was due to an oversight and the Discharger will replace the bulbs and update the Standard Operating Procedures (SOPs) to ensure the bulbs not exceeding the recommended hours in the future. |
