Total Event Precipitation(inches): 1.91 in
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 Structure(pipe,ditch,etc.): Pipe/Culvert
Receiving Stream:
Describe the industrial activities that occur within the outfall drainage area:
Vehicle maintenance and compositing

2. Color: Describe the color of the discharge using basic colors(red,brown,blue,etc.)and tint
(light,medium, dark)as descriptors: 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 3 ® 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 2 Q 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 2 3Q 4 5
7. Is there any foam in the stormwater discharge? O Yes O 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? O 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.
