1. Linking BMPs to Pollutant Sources

2. After impairments are understood, pollutant causes and sources known, pollutant loads estimated, critical areas identified…. it’s time to select the treatment measures – BMPs – that will achieve your goals.

3. Linking BMPs to Sources Match BMP to pollutant(s) Match BMP to source(s) Consider pollutant transport/delivery Evaluate load reduction capability Cost Acceptability/practicality

4. Match BMP to pollutant(s)

5. USDA-NRCS Conservation Practice Physical Effects (CPPE) http://efotg.nrcs.usda.gov/references/public/IN/IndianaCPPE-12-2006-Corrected.xls adapted from:

6. Match BMP to source(s)

7. Consider pollutant transport/delivery BMP interventions in NPS pathways: Availability/pollutant prevention (e.g., NMP) Detachment (e.g., conservation tillage) Transport (e.g., WASCOB) Delivery (e.g., filter strip, riparian buffer)

8. Evaluate load reduction capability Stormwater/Urban (BMP Effectiveness database; Menu of BMPs) Agriculture (Ag Management Measure document) Forestry (Forestry Management Measures document) Mining (Development document for proposed Effluent Guideline for Mining) www.epa.gov/nps

14. Cost Look at experience in other watershed programs in the region NRCS cost tables, other programs

15. Cost http://efotg.nrcs.usda.gov/references/public/IN/Average_Annual_Cost_2007.xls

16. Acceptability/practicality Look at what’s worked and what hasn’t Consider costs/benefits Property ownership/site access Look for added benefits Use a combination of techniques

17. Rank alternatives
