Information for this page has not been developed. It is anticipated this page will be populated in winter of 2014

Use this Quick Guide if you do not currently use a model, calculator, or similar tool to calculate pollutant loads or load reductions.

Gathering BMP reduction information

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 decide which category the BMP belongs to

Information: Note: A BMP may not be reported in more than one category.
  • Use Category 1 if all of the following apply.
    • Pollutant loadings from the BMP/activity can be estimated using an appropriate method
    • The pollutant is phosphorus, TSS, fecal coliform, or E. coli
    • The BMP/activity was constructed within your jurisdiction (upstream of your MS4's outfall)
    • The BMP/activity was in operation the past year
  • Recommend using Category 2 if the pollutant is chloride, but Category 1 may be used if you have detailed records and can justify your methodology.
  • Use Category 2 if any of the following applies.
    • Pollutant is Biochemical Oxygen Demand (BOD), Nitrogenous Biochemical Oxygen Demand (NBOD), chloride, or thermal loading
    • Pollutant reduction information from the BMP/activity is not readily available using an appropriate method
    • You contribute(d) to the implementation of the BMP/activity but the reduction in pollutant loading occurs outside your jurisdictional area (e.g. you contributed funding to a BMP in another MS4's jurisdiction)
    • The BMP/activity was in operation the past year


STEP 4: For Category 1 BMPs, determine reductions in pollutant loading. For guidance, including calculation methods, see Category 1 - Summary of quantitative reductions.

STEP 5: For Category 1, in the column with the applicable reporting year (Column E for 2014, Column F for 2015, 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 2014. Subsequent years will show the 2014 reduction plus any reductions achieved in the reporting year.
