Phone No. 704-318-5523
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
Regional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:
(Signature of Permittee or Designee)
1. Outfall Description:
Outfall No. 1
Receiving Stream:
Structure (pipe, ditch, etc.)
Pipe/Culvert
Describe the industrial activities that occur within the outfall drainage area:
Vehicle maintenance and and compositing

SWU-242, Last modified 07/28/2017

2. Color: Describe the color of the discharge using basic colors (red, brown, blue, etc.) and tint
(light, medium, dark) as descriptors: Medium -Brown to Dark -Brown
3. Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil, weak
chlorine odor, etc.): Odors detected, likely due to composting.
4. Clarity: Choose the number which best describes the clarity of the discharge, where 1 is clear
and 5 is very cloudy:
1 2 03 4 5
5. Floating Solids: Choose the number which best describes the amount of floating solids in the
stormwater discharge, where 1 is no solids and 5 is the surface covered with floating solids:
1 Q 3 4 5
6. Suspended Solids: Choose the number which best describes the amount of suspended solids in
the stormwater discharge, where 1 is no solids and 5 is extremely muddy:
1 20 3 4 5
7. Is there any foam in the stormwater discharge? O Yes
8. Is there an oil sheen in the stormwater discharge? OYes
9.
O No. No
O No. No
Is there evidence of erosion or deposition at the outfall? ® Yes O No. Yes
10. Other Obvious Indicators of Stormwater Pollution:
List and describe No other indicators.
Note: Low clarity, high solids, and/or the presence of foam, oil sheen, or erosion/deposition may be
indicative of pollutant exposure. These conditions warrant further investigation.
