General Permit Number NCG160000
Certificate of Coverage No: NCG160218
GRI No. 4629
Dear Ms. Kay:
On behalf of Boggs Materials, Inc. (Boggs), please find attached results of stormwater outfall
sampling that was conducted on August 25, 2020 for the Stafford Street Asphalt Plant facility in
Monroe, Union County, North Carolina. Water samples were collected from the outfalls SDO-2
through SDO-4 and SDO-6 by Boggs personnel on August 25, 2020 in accordance with the SWPPP
and sampling requirements of the permit. Please note that per Boggs personnel, there was no
discharge from outfall SDO-1, SDO-5, SDO-7 and SDO-8. Therefore, no samples could be collected
from these outfalls. Water samples were analyzed for total suspended solids and non -polar oil and
grease. No detectable concentrations of total suspended solids or oil and grease were report in
any of the samples that were collected during the August 2020 sampling event. 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.

'Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a check mark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge
°requirement. See General Permit text, Table 1, identifying the especially sensitive receiving water classifications where the more protective benchmark
applies.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format, "<XX mR/L", where XX is the numerical value of the
detection limit, reporting limit, quantitation limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text

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
Office.
