Zahid,
Enclosed you will find our two week notification letter for a Tier II Zinc benchmark exceedance at ISWO04 (ROS). The
original letter for this benchmark exceedance is being sent to you directly via USPS certified mail.
The benchmark for Zinc is 126 ug/L and the analytical result was 165 ug/L. This Zinc concentration is down from the Tier
I Zinc exceedance of 205 ug/L discussed below. There was no Copper benchmark exceedance for this monitoring period.
Samples were collected December 14, 2022 and results were received December 29, 2022.
We will document these exceedances and our response/actions within our SWPPP per Part D, Condition D-6. We will
also document within our SWPPP the other obligations addressed in Table 3. Monitoring frequency is also being
increased from quarterly to monthly.
If any questions or discussions are needed, please do not hesitate to contact Greg Beaver, McGuire Environmental Field
