Discussion Topics:
• Presentation on inter-relatedness of stormwater, ELGs, and TMDLs
• Presentation on Chesapeake Bay Executive Order (May 2009) and upcoming Chesapeake Bay
TMDL (Anticipated in mid-2010)
• Implications of TMDL on non-residential construction
• Possible collaboration on outreach/education and innovative approaches to stormwater
management (e.g., self policing)

Background:
• Chesapeake Bay Executive Order Web site: copy of the EO, support documents, reports, a blog
and other information http://executiveorder.chesapeakebay.net/

A TMDL sets strict discharge limits (essentially, pollution budgets) for those pollutants that are
preventing a water body from meeting its water quality standards. TMDLs are developed in two steps
by: 1) calculating the maximum amount of a pollutant that a waterbody can take in and still meet water
quality standards and then 2) distributing that amount among all "point sources" (i.e., storm water
discharges from construction sites) and "nonpoint sources" (i.e., agricultural runoff) that discharge the
pollutant. Using this framework, states will develop cleanup plans for each waterbody not meeting its
water quality standards.
