Dear Sir or Madam:
RECFivFD
JAN a 12020
C13-P41 r«AL HLES
bWN 956T10N
Enclosed are the results of December 2019 Monthly Storm Water Discharge
Outfall Monitoring Report. After two consecutive tests with pH being out of
range, June and October of 2019, we started monthly sampling per the tiered
responses laid out in our Storm Water Permit. Outfall No. 1 did not flow during
this event. We have exceedances for Copper in Outfalls 2 and 3, and
exceedances for Zinc at Outfalls 2, 3 and 4. We were granted relief from the
Tiered responses for our Copper and Zinc exceedances in January of 2015.
We conducted several walk-through's as well as held several brainstorming
events where we explored possible acidic exposure. We sampled virgin
rainwater as well with this test and found the pH of the virgin rainwater to be 4.8.
This would explain the low pH at our outfalls. We will test again in January to
verify this claim. If we are able to validate this information we will then pursue
relief from monthly sampling.
If you have questions or concerns, please feel free to contact me.
Respectfully Submitted,
Aubrey Meadows

rvuwnuuy �empung (inszeaa of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'- For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The iota) precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more'protective benchmark applies.
' Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EP.-.
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities :hat incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the --oral toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provision=- of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

format. When results are below the applicable limits, they must be reported in the format "<XX mg/L" where XX is the numerical value of the detection
mil, reporting limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.
