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 I
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
I interval does not apply if the permittee is able to document that a shorter interval is representative for
1 local storm events during the sampling period,and the permittee obtains approval from the local DEMLR I
I 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. 2 Structure(pipe,ditch,etc.): Pipe/Culvert
Receiving Stream:
Describe the industrial activities that occur within the outfall drainage area:
Vehicle maintenance 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: Light-brown
3. Odor: Describe any distinct odors that the discharge may have(i.e., smells strongly of oil,weak
chlorine odor, etc.): Light odor detected.
4. Clarity: Choose the number which best describes the clarity of the discharge,where 1 is clear
and 5 is very cloudy:
1 2Q 3 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 02 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? ®Yes 0 No. Yes
8. Is there an oil sheen in the stormwater discharge? OYes ®No. No
9. Is there evidence of erosion or deposition at the outfall? ®Yes 0 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.
