Reference: Semi -Annual Stormwater Monitoring Reports for Cook Brothers Lumber Company,
Franklin, Macon County, North Carolina — October 2019
Dear Division of Water Resources:
On October 8, 2019, Richard Beale with Beale Environmental Consulting conducted the semi-annual stormwater
monitoring inspection at the Cook Brothers Lumber Company facility in Franklin, Macon County, North
Carolina in accordance with the new requirements specified in the North Carolina Department of Environment
and Natural Resources (NCDENR) NPDES General Stormwater Permit Renewal, COC #NCG210171, dated
August 1, 2018 and die facility Stormwater Pollution Prevention Plan (SWP3). The SWP3 was updated in
October 2018 and is valid until October 2023. The permit was renewed by the NCDENR on August 1, 2018.
Visual Observations
1. No obvious environmental contaminants (color, odor, floating solids, excess total suspended solids, oil
sheens, etc.) were observed at any of the three outfalls on the property.
2. There was no visual evidence of petroleum leaks or spills on the site.
3. All containers of petroleum -based fuels and/or lubricants were properly stored under roof.
4. Rainfall amounts were measured by the onsite rain gauge.
5. Damaged silt fencing along the property boundary to the north of the log yard has been repaired and/or
replaced. In addition, new silt fencing has been installed along the drainage ditch to Outfall #3 west of
the log yard. Photographs are attached.
The NCDENR Qualitative Monitoring Reports for this sampling event are enclosed.
Field Sampling and Analysis
Sampling activities were conducted during a measurable rainfall event where a total of 0.91 inches of
precipitation occurred during the stormwater event, as measured by the onsite rain gauge.
Grab samples were collected at two of the three outfalls on the property (Outfalls # 1 and #3). There was no flow
in Outfall #2. Conditions have been extremely dry and although this was a measurable event there was minimal
flow in Outfall #3 and no flow in Outfall #2.
Samples were placed in clean containers provided by Environmental Testing Solutions, Inc. (ETS), a NC
certified laboratory (NC Certification #600).
The samples collected for Total Suspended Solids (TSS) were placed in one -liter polyethylene bottles and the
samples designated for Chemical Oxygen Demand (COD) analysis were placed in 120-milliliter polyethylene
bottles that contained 1:1 sulfuric acid as a preservative. Pursuant to the August 1, 2018 NCDENR testing
requirements, an analysis for pH was not conducted.

The samples were transported, under Chain -of -Custody, to ETS, located at 351 Depot Street in Asheville, NC
28802, phone number [phone]. Samples were analyzed for TSS using Standard Method 2540D and
COD using HACH Method 8000 (Standard Method 5220D).
Laboratory Results
The analytical results for this sampling event are presented in Table l:

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark 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 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 m¢/L", where XX is the numerical value of the
detection limit, reporting 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.

County: Macon Phone No. [phone]
Inspector: Richard Beale
Date of Inspection: 10/8/2019
Time of Inspection: 11:15
Total Event Precipitation (inches): 0.91
Was this a "Representative Storm Event" or "Measureable Storm Event" as defined by the permit?
(See information below.)
Yes X No
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.
