Use this Quick Guide if you do not currently use a model, calculator, or similar tool to calculate pollutant loads or load reductions.
The following guidance assumes the permittee has already completed BMPs-activities tab and therefore has already made a list of their BMPs.
STEP 1: Define the watershed boundaries of TMDL study areas that intersect your jurisdiction
STEP 2: For each BMP from the BMPs-activities completed worksheet, determine the TMDL watershed(s) from which each BMP is reducing pollutants
STEP 3: For each BMP listed on the BMPs-activities completed worksheet, decide which category the BMP belongs to
STEP 4: For Category 1 BMPs, determine reductions in pollutant loading. For guidance, including calculation methods, see Category 1
STEP 5: For Category 1, in the column with the applicable reporting year (Column E for 2019, Column F for 2020, etc.), enter pollutant loading reductions for each applicable TMDL. In the first year of reporting, this number will reflect the amount of pollutant reduced by all BMPs together up to the end of 2019. Subsequent years will show the 2019 reduction plus any reductions achieved in the reporting year.
STEP 6: In column D, report the units used for your reduction report.
STEP 7: If desired, complete columns L and M. MPCA approved calculation methods can be found by clicking the link in the column heading. MPCA highly recommends tracking your methodology for determining these numbers.
Step 8: For Category 2, in the column with the applicable reporting year, enter the number of Category 2 BMPs. In the first year of reporting, this number will reflect all Category 2 BMPs up to the end of 2019. Subsequent years will include the number of BMPs for 2019 plus any BMPs implemented in the reporting year.
