11. www.straughanenvironmental.com creating a sustainable world States demonstrate: –How the reductions will be achieved; i.e., which sectors; municipal and industrial wastewater treatment plants, septic systems, urban stormwater, and agricultural discharges will provide the nutrient and sediment load reductions necessary to achieve the waste load allocations of the Bay TMDL. –Address existing as well as any future nutrient and sediment sources associated with planned future development.

14. www.straughanenvironmental.com creating a sustainable world For point source, stormwater, and septic components of the plan MDE organized local teams that developed: –What can be implemented to achieve the targeted reductions –How the implementation actions will be achieved (new local ordinances and revenue sources) –Two-year milestones that reflect near-term implementation actions and steps to be taken between July 1, 2011 and June 30, 2013 Phase II WIP Process in Maryland

15. www.straughanenvironmental.com creating a sustainable world For Agriculture MDE formed agricultural work groups, organized for each soil conservation district Where local team strategies were not submitted, or fell short of the Final Target, the State supplemented the plans. Phase II WIP Process

16. www.straughanenvironmental.com creating a sustainable world To achieve the 2017 Interim Reductions –Point Source Sector - Major (>.5MGD) wastewater treatment plant upgrades to ENR –Agriculture Sector – Significant reduction from cropland, some reduction from AFOs, nurseries and pasture land –Stormwater Sector – Significant reduction from MS4 permittees retrofitting developed land with stormwater BMPs, also controlling fertilizer application and requiring forested stream buffers –Septic Sector - 60% in Critical Area upgrade or connection to an advanced waste water treatment plant. Phase II WIP Strategies

The Great Lakes, Gulf of Mexico, San Francisco Bay, and many others. Watershed based approach, addressing all source sectors. Watershed Based Approach

25. www.straughanenvironmental.com creating a sustainable world Take a holistic approach to the issue –Understand all of the changes made to State law and regulations and incorporate the impacts of those programs into your reporting Changes to Septic system regulations Focused Growth –Use GIS tools to think about nutrient reductions from a watershed based perspective Locate opportunities for off site nutrient reductions Prioritize improvements to targeted watersheds How can Local Governments Meet WIP goals without breaking their budgets??

26. www.straughanenvironmental.com creating a sustainable world Make reduction strategies Standard Practice –Incorporate ESD and low impact strategies into all construction programs –Incorporate funding for those strategies into budgets for capital projects Examine the full range of strategies available to determine which mix of approaches maximize reductions more efficiently How can Local Governments Meet WIP goals without breaking their budgets??
