Inspection Date: 11/03/2020 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
A routine compliance inspection of the facility was conducted on November 3, 2020. All outfalls were observed during the
inspection, and there were no apparent deficiencies with the SWPPP or requirements of the permit
At the time of inspection, the monitoring of outfall #2 was being conducted following Tier Two response guidelines due to
readings of aluminum higher than the benchmark. Outfall #2 was revealed to be a small pit which collects sheet flow from
the surrounding gravel lot. The pit has no drain and no mechanism to stir or empty it. It appears that during rainfall events it
collects runoff until it's full then discharges to the downstream ditch from the surface of the pit. Samples are reported to have
been collected from the surface of the pit. Both the location and method of sampling may be contributing to the high levels of
aluminum in the samples and may not be representative of runoff from the site. These factors must be evaluated as the
facility works toward tier relief.
Please contact this office to address resolution of the tiered response and actions to be taken to resolve the issues
associated with Outfall #2.
