RE: General Permit No. Nnfla074401Benchmark Sampling Results
Dear Mr. Davidson:
On May 31, 2016 we received the test results for our May 20, 2016 stormwater sampling event.
The values reported have exceeded our Benchmark Values for Cooper and Zinc. In
accordance with the Tier Three response requirements, we have continued to perform the
required monthly analysis and have instituted the suggested housekeeping BMP's suggested by
Ms. Shawna Riddle of your department.
In addition, we are monitoring internal stations in an attempt to isolate the source and instructed
our lab to run total dissolved solids on each sample in order to gain a better understanding of
the source and the potential to ultimately reduce these metals in the stormwater runoff. In the
near future, we will be providing a summary of our efforts to date for your review with the goal of
pursuing a request to be released from Tier Three monitoring. Any thoughts that you or Ms.
Riddle may have on this matter would be greatly appreciated. If you should have any
questions, feel free to contact me at [phone].
Sincerely,
Jody Splawn

1 Monthly sampling(instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the
same outfall.
2 For sampling periods with no discharge at any single outfall,you must still submit this discharge monitoring report with a
checkmark here. i .
3The total 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.
4 See General Permit,Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.

s 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 EPA 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 that 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 total 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 provisions of the solvent management plan included in the Stormwater Pollution Prevention Plan."

Note: Results must be reported in numerical format. Do not report Below Detection Limit, BDL,<PQL, Non-detect, ND,or other similar non-
numerical 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 limit, 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
