Dear Mr. Curry:

documentation of annual certification, monthly and annual facility inspection reports, annual non-
stormwater discharge inspection report, and annual employee trainings were not available at the time of
inspection.
Other Observations
The facility only samples one outfall from the retention pond in the front of the facility but at least two
other outfalls were identified during the inspection. There was a significant amount of debris from the
