Stormwater Monitoring
Enclosed is the monthly Stormwater Discharge Monitoring Report for August 2016. Orange
County is currently in Tier II monitoring for the facility due to high TSS. The report indicates no
discharge for this month.
There were rain events that had a qualifying amount of precipitation, but they did not have the
required 72 hours in-between rain events. Additionally,the events occurred during a time period
that the first flush discharge could not be captured in time to be collected or started too late to be
delivered to the testing laboratory within the hold time requirements for the testing laboratory
(maximum 6 hrs for E.Coli.).
Orange County continues to monitor the installed BMP's that help to control the amount of
onsite erosion and subsequent discharge of contaminated water; this includes the monitoring the
growth of our vegetative cover and minimizing the amount of disturbed land. We also took
advantage of the extremely dry weather to perform maintenance on our north sediment basin and
tried to enhance some of the controls to improve sediment removal efficiency.
If you have any questions, please contact me at [e-mail] or 919-968-2788.
Sincerely,
