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 culyerts.was done before the abatement deadline. •Seriousness is extremely-low due to the nature of the event that caused the problems, short diiration;!and limited•acttial 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'diapute 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 cauaed,by the storm.. GOOD''FAITS: 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 r2maining culverts was done by August 13 for one and August.l7 for the second. Both were finished within the abatement deadline date. Repair work wag well underway. upon your 'arrival, all ditches and most culverts returned to design capacity, and the two remaining culverts partially•reatored prior to` inspection team. departure: .Good faith .credit should be at the maximum. ~ . NOV C-94-020: Failure to Maintain Pond Primary. .Spillway Structures. SERIOUSNESS: The extent of actual or potential damage caused by this NOV is extremely Iow. 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.atorm. '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
