Report for March 2015
Enclosed you will find the original and 1 copy of the compliance reports on forms SWU-
247 and SWU-242 as required by Permit No. NCS000134 for Outfall 003.
These reports are required since Avoca, Inc. has entered the Tier 2 step after the
benchmark values were previously exceeded for 2 consecutive sampling periods for
outfall 003 during semi-annual sampling events on May 22, 2012 and December 12,
2012. Avoca has implemented the Tier 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.
The COD and Phosphorus benchmark values were exceeded with the most recent
samples collected on 3/28/2016.
The 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.

mg/L.
