Stormwater Discharge Outfall SW-1 has 'sheet flow' only.
Stormwater Discharge Outfall SW-2 is in Tier I status due to 9/13/2020 Copper sampling result being
above the benchmark value. Therefore, we are required to conduct monthly monitoring at this outfall until
three consecutive sample results are below the benchmark values or within benchmark range.
Stormwater Discharge Outfall SW-2 is also in Tier I status due to 9/13/2020 TSS sampling result being
above the benchmark value. Therefore, we are required to conduct monthly monitoring at this outfall until
three consecutive sample results are below the benchmark values or within benchmark range.
Stormwater Discharge Outfall SW-3 cannot discharge due to metal plates on the inlets.
Section B of the permit identify six Analytical Monitoring Requirements for sampling. There was not a rain
event this month compliant with these six Requirements. Therefore, no samples were collected from
Stormwater Discharge Outfalls SW-1, SW-2, or SW-3. The attached table identify which Requirement(s)
prevented sampling at Stormwater Discharge Outfall SW-2. The monitoring report indicate "No Flow".
