To Whom It may Concern,
Please find attached(COC Number NCG030447) our Semi-Annual Stormwater Discharge
Monitoring Report for Caterpillar located at 5000 Womack Rd., Sanford,NC. Upon reviewing
the report you will notice that our outfall location is above the benchmark range for total
suspended solids, copper and zinc which requires us to perform a"Tier One"according to the
permit.
We have conducted a stormwater inspection of our facility since the sampling period and have
potentially identified some possible causes of the exceedance of the established benchmark. We
will implement some operational control measures for the parameter's of concern, with the
anticipation of bringing the concentration's within regulatory limit.
If you have any questions,please do not hesitate to call me.
Best Regards,
Kevin Staubus

All permits require qualitative monitoring to be performed during a"measurable storm event."
A"measurable storm event"is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period,and the permittee obtains approval from the local DEMLR
