The following is a quick guide to complete the BMPs-Activities completed tab.

Gathering BMP information

STEP 1: Inventory BMPs that

  • are treating water discharged to waterbodies with an approved TMDL as indicated in your form
  • reduce WLA in a TMDL project area
  • you described in your Compliance Schedule on your TMDL Attachment Spreadsheet at the time of application
  • have been operational since the baseline year of that TMDL but not prior to the baseline year
  • meet criteria for category 1 or category 2 BMP types


STEP 2: Identify the location of your MS4 in relation to watershed boundaries and the TMDL study area
STEP 3: Plot the location of inventoried BMPs for which you have geographic locations
STEP 4: Determine from which TMDL the BMPs reduce pollutants

Enter BMP information into the spreadsheet
