To Whom It may Concern,
We are performing monthly Stormwater monitoring/reporting for all parameters to follow the
Tier Two permit process for our elevated total suspended solids(COC Number NCG030447).
Please find attached (COC Number NCG030447) our Stormwater Discharge Monitoring Report
for Caterpillar located at 5000 Womack Rd., Sanford, NC. Upon reviewing the report you will
notice we are below the benchmark range for all areas. We will continue to perform monthly
monitoring until we have three consecutive test results below benchmark for Total Suspended
Solids per the requirements for us to perform monthly testing while in"Tier two" according to
the permit.
If you have any questions, please do not hesitate to call me.
Best Regards,
e(w.v..1
