Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The 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 3, 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 mg/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.

To Whom It May Concern:
S&ME, Inc. is providing stormwater reporting services on behalf of the D&S Asphalt Materials facility in Tryon,
North Carolina. Our services were performed in general accordance with S&ME Proposal ENV-015-10 dated
March 12, 2010 and email correspondence from Mr. David Loftis to Mr. Matt Davis with D&S Asphalt Materials facility
dated June 9, 2010.
o Stormwater Sampling Event
On May 23, 2017, Mr. Davis collected a stormwater sample from the stormwater discharge outfall (SDO) located
on the property. The stormwater sample was submitted to Environmental Lab Sciences (ESC) for analysis for Total
Suspended Solids (TSS). On -site vehicle maintenance does not take place at the facility; therefore, the analysis of
the stormwater sample for pH and oil & grease by EPA Method 1664E is not required under the National Pollutant
Discharge Elimination System (NPDES) General Permit No. NCG160000. The table below provides a comparison of
the laboratory results with the benchmark values included in the NPDES General Permit No. NCG160000
associated with the site.
Table 1— May 2017 Sampling Results
TSS 1 101 mo/L 1 100
mg/L = milligrams per liter
A copy of the laboratory report and corresponding chain -of -custody is attached. According to Mr. Davis, the May
23, 2017 rainfall event produced 1 inch of precipitation. As depicted in Table 1, the TSS concentration in the
sample was 101 mg/L, which exceeds the benchmark value of 100 mg/L. The causation of the exceedance is
unknown because no disturbed areas or areas with sporadic vegetation cover were observed.
In response to the TSS exceedance, Mr. Davis collected a second sample from the SDO on August 7, 2017.
According to Mr. Davis, the rainfall event produced approximately 1 inch of precipitation.

S&ME Project No. 1411-07-064
The sample was submitted to ESC for analysis for TSS. TSS was detected in the sample at a concentration of 18.2
mg/L, which is less than the permitted benchmark of 100 mg/L. A copy of the laboratory report and
corresponding chain -of -custody is attached.

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The 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.
4 See General Permit text, Table 3, 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 mg/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.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be

some permits do not have this requirement. Please refer to these definitions, if applicable.
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
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.

S&ME Project No. 1411-07-064
To Whom It May Concern:
S&ME, Inc. is providing stormwater reporting services on behalf of the D&S Asphalt
Materials facility in Tryon, North Carolina. Our services were performed in general
accordance with S&ME Proposal ENV-015-10 dated March 12, 2010 and email
correspondence from Mr. David Loftis to Mr. Matt Davis with D&S Asphalt Materials
facility dated ,tune 9, 2010.
STORMWATER SAMPLING
On March 14, 2015, Mr. Davis collected a stormwater sample from the stormwater
discharge outfall (SDO) located on the property. According to Mr. Davis, the March 14,
2015 rainfall event produced approximately 1.5 inches of precipitation. Mr. Davis
completed the Stormwater Discharge Outfall Qualitative Monitoring Report (see
attached) for the sampling event.
The stormwater sample was submitted to Pace Analytical Services, Inc. (Pace) for
analysis for Total Suspended Solids (TSS), pH, and oil & grease by EPA Method 1664.
Pace inadvertently discarded the sample material that was to be analyzed for pH;
therefore, there is no pH data available for the March 14, 2015 sampling event.
Historical pH data collected at the site ranged from 6.3 to 8.2; suggesting that the
stormwater from the SDO consistently falls within the Benchmark Value of'6.0 —9.0
outlined the NPDES General Permit NO. NCG160000.

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.
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
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.
