'Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The 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.
45ee 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 ma/V 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".

[A1 permits require qualitative monitoring to be performed during a "measurable storm event." j
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:

2. Color: Describe the color of the discharge using basic colors (red, brown, blue, etc.) and tint
(light, medium, dark) as descriptors: clear
3. Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil,
weak chlorine odor, etc.): none
4. Clarity: Choose the number which best describes the clarity of the discharge, where 1 is
clear and 5 is very cloudy: Qualitative Analysis =1
(1 2 3 4 5)
S. 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:
Qualitative Analysis =1
1 2 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:
Qualitative Analysis =1
1 2 3 4 5
7. Is there any foam in the stormwater discharge? Yes X— No
8. Is there an oil sheen in the stormwater discharge? Yes 2L_ No
9. Is there evidence of erosion or deposition at the outfall? Yes CX No
10. Other Obvious Indicators of Stormwater Pollution:
List and describe None
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.
