Spreadsheet Tool for Estimating Pollutant Loads (STEPL) webinar

The DNR and EPA offered a hands-on technical training on the Spreadsheet Tool for Estimating Pollutant Loads (STEPL) [exit DNR] on August 5, 2014. A recording of the training session and the presentation materials are available.

This training was specifically offered for DNR and county LCD staff, particularly those counties who are recurring Targeted Runoff Management (TRM) and Notice of Discharge (NOD) grantees. Beginning with the CY 2015 TRM and NOD grant awards, grantees will be required to provide modelled pollutant load reduction estimates (phosphorus, nitrogen and sediment, as applicable) to the DNR as part of their project evaluation strategy in the reimbursement request/final report. Grantees will have the flexibility to select and use an appropriate model to calculate those load reductions. One of the models that EPA offers, and DNR is subsequently offering to grantees, is STEPL.
