Dear Sir or Maddam:
Enclosed are the results of January 2020 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. December testing showed similar results with pH
out of range on the low end. In December, we sampled virgin rainwater using
plastic pools to capture the rainwater before it contacted our property. We found
then that the pH of the rainwater coming to us was a 4.8 pH. We sampled virgin
rainwater again in January for this test and again, we found the pH of the virgin
rainwater to be 4.3 pH. We have exceedances for Copper in Outfalls 2 and 3,
and an exceedance for Zinc at Outfall 2. We were granted relief from the Tiered
responses for our Copper and Zinc exceedances in January of 2015.
We have had two consecutive tests from December 2019 and January 2020
where the rainwater falling on our property has measured at a 4.8 and 4.3 pH
respectively. We would like to request relief from the monthly sampling tiered
responses as the rainwater falling on our property is already out of the
benchmark range. Please let us know if we can discontinue the monthly
sampling.
If you have questions or concerns, please feel free to contact me.
Respectfully Submitted,
Aubrey Meadows

2 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
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.
5 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).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

Facilities that incorporate a solvent management plan into the Storrwater 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), l 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 me/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, ar Tier .3 responses. -See-General Permit text.
