  2. Stormwater Systems in the District • Municipal Separate Storm Sewer System is roughly 41 square miles • Combined Sewer System is roughly 21 square miles • “Outflow” pipes empty CSS or MS4 stormwater into the Rock Creek, Potomac, and Anacostia watersheds MS4 MS4 CSS MS4

  3. CSS vs. MS4 1 pipe 2 pipes 1/3 of the District 2/3 of the District Maintained by WASA, regulated by US EPA Maintained by WASA, regulated by DDOE

  4. Why is Stormwater a Problem? • Stormwater causes physical damage to streams by eroding banks and stream channels. • Sediment carried by stormwater negatively impacts water quality and aquatic habitat for fish and vegetation • 70% of Anacostia sediment loads are from streambank erosion • Stormwater carries pollutants into our rivers and streams including: • Nutrients that increase growth of algae • Bacteria, chemicals, and trash that are harmful to people and wildlife Ft.

  5. Brief MS4 Permit History • EPA permit required to discharge stormwater runoff via the MS4 system. • U.S. EPA issued the District an updated MS4 permit in 2004, but this permit was challenged legally. • After a two year mediation process, a Best Management Practices Enhancement Package was negotiated in November, 2007. • The BMP Package expands the scope of the 2004 permit requirements.

  6. Best Management Practices Enhancement Package • The package is innovative and represents a shift towards increased responsibility and accountability for the District’s Stormwater Administration. • Several measureable and quantifiable milestones with specific deadlines; for example, • 13,500 additional trees by 2014; at least 4,150 per year • Construct 17 Low Impact Development projects by August, 2009 • Retrofit 50 catch basins to control trash by February, 2009 • The enhancements in the package will serve as the baseline for future permits beginning in early 2009.

  7. Costs of Meeting MS4 Permit and BMP Enhancement Package Requirements

  8. MS4 Permit Compliance Expenses Fiscal Years 2001-2009^ (In 000’s of Dollars) * FY 08 incomplete expenses ** FY 09 projected expenses ^ FY 01 – FY 06 date from February, 2008 RESOLVE report

  9. Estimated FY 2009 Revenue Under Previous Stormwater Fee Structure • $4.13 million total revenue

  10. Adjusting Stormwater Fees • To meet additional permit/BMP enhancement package compliance costs for FY 2009 and subsequent years • Reduce stormwater runoff through implementation of best management practices (BMP) • Provide relevant District Government agencies with funds to fulfill their additional permit responsibilities

  11. District Government-wide Responsibilities Projected Allocation of FY 2009 MS4 Funds* *Final allocation subject to change

  12. Budgeted FY 2009 Costs of Meeting Additional BMP Enhancement Package *Final allocation subject to change

  13. Fee Increase Process • 11/2007 - EPA-DDOE MS4 Permit Letter Agreement signed • 3/2008 - Stakeholder / Citizen Task Force focused on Stormwater Management Proposed fee authority to Council • 6/2008 - Budget Support Act passed by Council • 7/2008 - Coordinated rate requirements with DC WASA • 8/15/08 - DDOE proposed fee increase regulation in DC Register • 9/15/08 - Public hearing and close of comment period • Majority of comments received were in support of proposal • Support from 17 environmental and community organizations • Comments also supported stormwater fees based on impervious surface methods • 9/26/08 - Final rule issued in DC Register • 11/1/08 - New fees become effective

  16. Monthly Customer WASA Bill *Assumes average monthly consumption of 8.33 Ccf, or 6,231 gallons

  19. Next Steps:Changes to Stormwater Fee Structure • DC WASA and DDOE are examining options to modify the current structure of the stormwater fees to a fee based on “impervious cover.” • Impervious cover includes hardened surfaces such as roofs, driveways and parking lots that cause stormwater to run off. • The result would be a shift in costs from properties with more green space to properties with more hardened or paved surfaces. • More information will be made available in early 2009 and notices will be published and public comments sought before any future fee change.
