"While the Obama administration is touting Virginia's pollution trading program as an 'innovative market-based approach' to cleaning up the Chesapeake Bay, Maryland's trading effort remains stuck in limbo after years of study and debate.

Environmental Protection Agency Administrator Gina McCarthy, U.S. Department of Agriculture Secretary Tom Vilsack and the head of the White House Council on Environmental Quality joined Virginia's Gov. Terry McAuliffe in Fairfax County Tuesday to endorse that state's trading program.

Federal officials called it a model for other states struggling with the high costs of cleaning up polluted waterways."
