PAGE 4 event. The probability of a storm of this magnitude occurring ie less than once in ten years. Although the capacity was reduced on the ditches and culverts, any additional flow which would occur would still report to sediment ponds. These structures were designed per regulation, to handle capacities from storm events up to a 10 year/24 hour. The design event was surpassed. All structures except two culverts were returned to their design capacities prior to departure of the inspection team on August 12. Clean-out of the other two culverts was done before the abatement deadline. Seriousness is extremely low due to the nature of the event that caused the problems, short duraiion, an3 limited actual and potential damage which may have occurred. FAULT: The unavoidable nature of the storm event, combined with the very quick response time to correct the identified areas indicate a very low fault value. Response time was delayed because of the extremely wet conditions and the labor dispute which did not allow a continuation of cleanup. Cleanup of the drainage system was well underway at the time of inspection. It continued throughout the inspection. The cleanup was progressing in a priority fashion with these secondary structures awaiting their turn. The failure to maintain was a direct result of the total disruption of the drainage system caused by the storm. GOOD FAITH: All but two culverts were completely cleaned prior to departure of the inspection team. All ditches were returned to design capacity. Completion of the clean out of the two remaining culverts was done by August 13 for one and August 17 for the second. Both were finished within the abatement deadline date. Repair work was well underway upon your arrival, all ditches and most culverts returned to design capacity, and the two remaining culverts partially restored prior to inspection team departure. Good faith credit should be at the maximum. NOV C-94-020: Failure to Maintain Pond Primarv__Spillwav Structures. SERIOUSNESS: The extent of actual or potential damage caused by this NOV is extremely low. The primary spillway for pond 008 had a leaking riser. This riser has never leaked prior to the major storm event because the water level in the pond has never been up that height. The increased water elevation was caused by the major storm. The amount of water leaking is minimal. The water is absorbed into the ground prior to reaching the CDPS sampling location. In other words, there was no regulated discharge. The gate valve leak at pond 007 was also dripping a
