]Inclosed you will find the original and 1 copy ofthe compliance reports on forms SWU-
247 and SWU-242 as required by Permit No. NCS000134 for Outfall 003.
These reports are required since Avoca, LLC. has entered the 'tier 2 step after the

2012. Avoca has implemented the "Pier 2 step as outlined in the permit. Tier 2 requires
monthly monitoring of the outfalls with exceeded benchmarks until 3 consecutive
samples are taken with values below the benchmarks. Avoca began the monthly sampling;
of'outfall 003 in January 2013.
There were NO benchmark values for Outfall 003 exceeded with the most recent
samples collected on 11/30/2019.
fhe following; benchmark values were exceeded with the samples collected on December
12, 2012 that triggered the Tier 2:
- The 'Total Suspended solids benchmark is 100 mg/L. The result from Outfall
003 was 117 mg/L.
- The COD benchmark is 120 mg/L. The result from Outfall 003 was 1014
mg/L.
- The Phosphorus benchmark is 2 mg;/1... '['he result from Outfall 003 was 6.47
mg;/L.
- The Nitrogen Benchmark is 30 mg/l_..

The following is the results of the samples collected from outfall #003 most recently
on 11/30/2019:
- Total Suspended Solids = 16 mg/L
- COI) = 64 mg/L
- Phosphorus = 0.53 mg/L
- Nitrogen = 2.59 mg/L
The results of the sampling were very favorable with no exceedances this month. Avoca
will continue to monitor the storm -water from outfall #O03 monthly. If you have any
Questions, please contact me at [phone] extension 287.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring ,to -be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:
