General Permit No. NCG060000
Certificate of Coverage NCG060379
Sanford,NC
Dear Tina Pedley:
This Office is in receipt of your request for a variance from the 72-hour storm interval outlined
in Section E-3 of NCG060000. The referenced section is quoted below for reference:
E-3. Methodology for Collecting Samples (a) Outfall monitoring efforts shall begin with the first
measurable storm event in the monitoring period that meets all the following conditions: i. Occurs
at least 72 hours after the previous measurable storm event unless E-3(b) applies, ii. Occurs
during the facility's normal operating hours, iii. Does not coincide with adverse weather
conditions, and iv. Is characteristic of the volume and nature of the permitted discharge. (b) The
72-hour storm interval may not apply if: i. The permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and ii. The permittee
obtains approval from the Division's Regional Office. iii. After authorization by the Division's
Regional Office, a written approval letter must be kept on site in the permittee's SWPPP. (c) Grab
samples shall be collected within the first 30 minutes of discharge from an outfall and continue
until all outfalls that are discharging have been sampled. (d) Outfalls that are not sampled during
the first measurable storm event in the monitoring period shall be sampled during the next
measurable storm event in the monitoring period until a sample has been collected. (e) If, during
the entire monitoring period, there is no discharge from an outfall during any measurable storm
event then the permittee shall: i. Report "No Discharge" in the DMR, ii. Note "No Discharge" in
the SWPPP, and iii. Submit the DMR within 30 days after the end of the monitoring period. 0
Lack of a discharge from an outfall for the monitoring period shall not constitute failure to monitor
as long as the above permit conditions are met. (g) If the sampled storm event coincides with a
known non-stormwater discharge that is deemed permitted under 15A NCAC 02 .0106, then this
shall be noted on the DMR.

Your request to reduce the time after a measurable storm event from 72 hours to 36 hours has
been considered. We must advise you that every attempt should be made to grab samples during
the first qualifying event at the beginning of the applicable monitoring period. We cannot agree
to a 36-hour storm interval, but we will accept samples when it has been at least 48 hours since
the previous measurable storm event.
If you have any questions, please contact me at tam.era.eplinr Weq.nc.gov or (336) 776-9654.
Sincerely,
Tamera Epliri;'PE
