2 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.
4 See General Permit text, Table 1, 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, etc. in mg/L. Conversely, where fecal coliform results exceed the dilution upper limit, report the result as ">XX".

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:

Outfall No. A Structure (pipe, ditch, etc.): dam at retention pond
Receiving Stream:
South Buffalo Creek
Describe the industrial activities that occur within the outfall drainage area: Equipment storage,
Employee parking, soil stockpile

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.): no odor
4. Clarity: Choose the number which best describes the clarity of the discharge, where 1 is clear
and 5 is very cloudy:

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:

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:

7. Is there any foam in the stormwater discharge? Q Yes Q No.
8. Is there an oil sheen in the stormwater discharge? QYes Q No.
9. Is there evidence of erosion or deposition at the outfall? Q Yes iD No.
10. Other Obvious Indicators of Stormwater Pollution:
List and describe Water color may be due to prior salt applications, this was the first measurable
event following snow/ice.
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.
