Watson Tanner Q. Mikell Christina E. Weisbruch Enclosed is the Tier 2 and Tier 3 response for C & C Scrap Iron & Metal Inc, NCG200342. This site has been in Tier 3 before, and will start to do monthly monitoring for qualifying storm events. The facility has reviewed and implemented Control measures and Best Management Practices to reduce stormwater pollution as much as is practicable. The facility is working on control measures as reported with the previous monitoring event. If you have any questions, please do not hesitate to contact me at 615-730-5059. cw/ 14296 Enclosures cc: Tony Cooke - C&C Scrap Sincerely, INDUSTRIAL ENVIRONMENTAL CONSULTANTS, LLC Christina Weisbruch Environmental Scientist www.iecnashviIle. coin NCG20 SWPPP TIER RESPONSE REVIEW FOR BENCHMARK EXCEEDANCE FACILITY: C & C Scrap Iron &Metal is REPORT DATE: 04/13/2022 N�� kNA- PREPARED BY: Christina Weisbruch Tier 1 Response ono ® Valid sampling results are above a benchmark value, or outside of the benchmark range, A any parameter at any outfall.

Immediately institute monthly monitoring for all parameters at every outfall where a sampling result exceeded the benchmark value for two consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three consecutive sample results are below the benchmark values or within the benchmark range. Monthly Monitoring Required? ® Yes ❑ No ❑ N/A Comments: Monthly monitoring should be implemented for all representative discharges according to the permit requirements, see #3 below. 3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly monitoring report indicating "No Flow" to comply with reporting requirements. When Monthly monitoring is required, it continues for all parameters at each outfall until 3 consecutive results are below benchmarks for all parameters. Track rainfall during the month using the on -site rain gage. These are the criteria for collecting a valid stormwater sample from a measurable storm event: • Dry weather with no rainfall the preceding 72 hours. • The sample must be collected within the first 30 minutes of discharge. • A discharge must occur • Sample at the outfall only Samples should only be collected if a discharge occurs while the facility is manned under these conditions. For example if there is no flow off the property there should be no sample collected. If rainfall occurs overnight, no sample should be collected due to the first 30-minute condition. Reporting is required even i('there is no samtle collected. 4. Maintain a record of the Tier Two response in the Stormwater Pollution Prevention Plan.

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.
