Attached is a signed copy of the Discharge Monitoring Report form for Period 1 for 2021 where all outfalls were sampled. This was the first heavy rainfall in about three weeks and total suspended solids in samples seem to be higher than normal. SDO-3, SDO-4, SDO-5 and SDO-7 all had exceedances in total suspended solids. After inspection of these outfalls, additional sediment and erosion control practices have been applied or are planned. The ditch up gradient of SDO-3 has been cleared and additional stone has been placed near the corrugated pipe where the sample for this outfall is taken. The stone will add additional filtration and retention time for the stormwater. For SDO-4 and SDO-5, silt fence has been ordered to replace parts of the silt fence that has deteriorated at the sample points. The up gradient ditch to SDO-7, will receive additional stone to improve the integrity of the ditch and increase retention time of the stormwater to help filter sediment. There were three outfalls over the benchmark for fecal coliform this period; SDO-1, SDO-3 and SDO-5. SDO-1 receives flow from an area located in Phase I of the landfill, which stopped receiving waste in the early 2000's. After inspection of this area, no known causes of the increase in fecal coliform could be found. It is assumed the source for fecal coliform in this sample was not due to waste, since the waste has been covered with 12 inches of dirt and has good ground cover. The exceedances in SDO-3 and SDO-5 were higher than normally seen. The clearing and additional sediment and erosion control practices applied to these outfalls as mentioned above, should also help reduce the fecal coliform bacteria found in these outfalls. Should you have any questions or require additional information/action with regard to this submittal, please do not hesitate to contact me at your convenience. Thank you for your attention in this matter. Y� Jaimie PicAu Environme tal Field Specialist GENERAL PERMIT NO. NCG120000 SAMPLES COLLECTED DURING CALENDAR YEAR: 2021_ CERTIFICATE OF COVERAGE NO.
