Revised Rule 6 Reporting Forms - IDEM Industrial Storm Water Permit

The Indiana Department of Environmental Management (IDEM) Office of Water Quality has created new state forms for all permitted facilities to complete and submit to meet the annual reporting and stormwater discharge monitoring reporting requirements of Rule 6.

Rule 6 requires each permittee to complete and submit an Annual Report. Annual Reporting is an effective way of ensuring the Storm Water Pollution Prevention Plan (SWP3) is current, potential pollution sources are identified, and Best Management Practices and corrective measures are implemented, properly designed and functioning, and are being maintained. An Annual Report is due no later than 365 days from submitting the Notice of Intent and must contain information obtained during the previous year of regulation. Subsequent annual reports must be submitted no later than 365 days from the previous report in years 2 through 5.

Rule 6 also requires each permittee to conduct annual storm water monitoring. A Storm Water Discharge Monitoring Report is due no later than 365 days from submitting the Notice of Intent. Subsequent annual storm water discharge monitoring reports must be submitted no later than 365 days from the previous report in years 2 through 5. Each year of the permit, permitted facilities are required to collect grab storm water samples from qualified rainfall. The samples must be sent to a lab and analyzed for any pollutant that has the potential to be present in a storm water discharge in addition to the following required 8 sampling parameters:
• pH;
• Oil and Grease;
• Nitrates plus nitrite nitrogen;
• Kjeldahl nitrogen, total (TKN);
• Phosphorous, total;
• Suspended solids, total (TSS);
• Chemical oxygen demand (COD);
• Carbonaceous bio-chemical oxygen demand (CBOD5)
