RECEIVED ® Yes ❑ No JUL 19 2016 CENTRAL FILES Please verify whether Qualitative Monitoring ,estl$errf�f�r#d during a "representative storm event" or "measureable storm event" (requirements vary, depending on the permit). Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a "representative storm event" or during a "measureable storm event." However, some permits do not have this requirement. Please refer to these definitions, if applicable. A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no precipitation. 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 DWQ Regional Office, By this signature, I certify that this report is accurate and complete to the best of my knowledge: (Signature of Permittee dYDesignee) Page 1 of 2 SWU-242, Last modified 7/31/2013 F 1.

Was this a "Representative Storm Event" or "Measureable Storm Event" as defined by the permit? (See information below.) ® Yes ❑ No Please verify whether Qualitative Monitoring must be performed during a "representative storm event" or "measureable storm event" (requirements vary, depending on the permit). Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a "representative storm event" or during a "measureable storm event." However, some permits do not have this requirement. Please refer to these definitions, if applicable. A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no precipitation. 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 DWQ Regional Office.

Color: Describe the color of the discharge using basic colors (red, brown, blue, etc.) and tint (light, medium, dark) as descriptors: very light brown tint 3. Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil, weak chlorine odor, etc.): No distinct odor 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 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: 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: 1 2 3 4 5 7. Is there any foam in the stormwater discharge? Yes No 8. Is there an oil sheen in the stormwater discharge? Yes No 9. Is there evidence of erosion or deposition at the outfall? Yes No 10. Other Obvious Indicators of Stormwater Pollution: List and describe pH: 8.87 Note: Low clarity, high solids, and/or the presence of foam, oil sheen, or erosion/deposition may be indicative of pollutant exposure.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a "representative storm event" or during a "measureable storm event." However, some permits do not have this requirement. Please refer to these definitions, if applicable. A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no precipitation. 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 DWQ Regional Office.
