On behalf of Carolina Ready Mix (Ready), please find attached results of stormwater outfall sampling that was
conducted on December 23, 2019 for the Carolina Ready Mix facility in Monroe, Union County, North Carolina. Water
samples were collected from the outfall of the stormwater piping by Ready personnel on December 23, 2019 in
accordance with the SWPPP and sampling requirements of the permit. Water samples were analyzed for pH and total
suspended solids. pH was also measured using a pH meter during the sampling event. The December 2019 sampling
results indicated that all of the sampled parameters were below the permit levels. The Stormwater Discharge Outfall
Monitoring Report is included in Appendix A, the Stormwater Discharge Outfall Qualitative Monitoring Report is
included in Appendix B, and a complete laboratory analytical report is included as Appendix C.
The next sampling event is scheduled to be conducted between January and June 2020 during a representative rainfall
event. Please do not hesitate to contact me at [phone], if you have any questions or comments.
Sincerely,
Rohit Shetty, P.E.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement Please refer to these definitions, if applicable.
1
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
3 precipitation.
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 DWQ Regional Office.
