Part A:Stormwater Benchmarks and Monitoring Results
For sampling periods with no discharge, you must submit this discharge monitoring form noting "No Flow"or"No Discharge"within
30 days of the end of that period to comply with permit reporting requirements.

Note: If you report a sampled value in excess of the benchmark value,or outside the benchmark range for pH,you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower,then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy)instead of 6 S.U. Readings from an on-site or local rain gauge(or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D,Table II of Chapter 40 Code of Federal Regulations(CFR) Part 122.
