Stormwater Program for Industrial Activity: Steps to Compliance
Step 13: Sample/monitor again, send in results
How do I sample again and make sure I will pass my benchmarks?
You’ve modified your BMPs and need to sample again. Get information on what you can do, based on frequently-asked-questions and answers from Permittees (developed over time within this step).
What to do if you have an exceedance after the end of year 4
1. Fill out a Benchmark Exceedance Report
If you’re a facility that did not pass your benchmark monitoring requirements in year 2 and also in year 4, you are required to submit a Benchmark Exceedance Report (BER). The BER will ask you to provide the following information:
- Describe the inability to meet the benchmark values.
- Describe in detail the technical basis and reasons why the benchmark values cannot be met.
The Benchmark Exceedance Report shall be submitted to the Agency no later than 30 days after the fourth sampling interval of the monitoring year.
The form and more detailed information about filling out and submitting the reports will be updated once it’s available.
2. Fifth year monitoring
If sampling conducted in accordance with fourth year monitoring resulted in a benchmark value exceedance, the Permittee shall conduct fifth year monitoring. The fifth year monitoring may be limited to only the benchmark parameter(s), and benchmark monitoring locations for which a benchmark value was exceeded during the fourth year monitoring.
Once the fifth year samples for each benchmark monitoring location(s) have been collected and analyzed, the Permittee shall compare the average of the fifth year monitoring results with the applicable benchmark value and refer to the following outcomes to determine what further action may be required.
Re-visit Step 10 to review information about how to sample. Also, this page will provide information on what specific sectors may be able to do to improve their benchmark monitoring results.
