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 me/L", where XX is the numerical value of the detection limit, reporting limit, etc. in mg/L.

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 permitter 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: (S'6mattire of Perniince or Designee) 1. Outfall Description: Oullall No. 2 Structure (pipe, ditch, etc.): Culvert running under facility from upstream Receiving Stream: Youngs Fork (Capering Creek) Describe the industrial activities that occur within the outtall drainage area: Numerous activities upstream before stream inlet running under Northwest Hardwoods property which includes City of Marion, NC activities. Northwest Hardwoods activities include only light lumber production only all on concrete and blacktop. Page I of 2 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: Dark tint 3. Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil, weak chlorine odor, etc.): No odor present 4. Clarity: Choose the number which best describes the clarity of the discharge, where I is clear and 5 is very cloudy: 1 2 3 4 0 5. Floating Solids: Choose the number which best describes the amount of floating solids in the stormwatcr discharge, where I is no solids and 5 is the surface covered with floating solids: 2 3 0 5 6. Suspended Solids: Choose the number which best describes the amount of suspended solids in the stormwatcr discharge, where I is no solids and 5 is extremely muddy: 2 3 4 O 7. Is there any foam in the stormwatcr discharge? Q Yes O No. 8. Is there an oil sheen in the stormwatcr discharge'?

Other Obvious Indicators of Stormwater Pollution: List and describe Possible upsteam activities produce a higher TSS than we would like to see at the inlet prior to entering our culvert under the property. 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.
