Maryland's House of Delegates just passed a bill that doubles the "flush tax" -- a fee on water use -- sending it to Gov. Martin O'Malleyfor his signature. Passing the bill was a key part of the governor's agenda this year.

The bill increases the fee from $2.50 per household per month to $5. Funds will be used to upgrade wastewater faciliites. It passed the House 89 to 48.

The bill (HB 446) was amended to exclude parts of the state, like Garrett County and parts of the Eastern Shore, that are not part of the Chesapeake Bay watershed. Del. Maggie McIntosh, the House floor leader, said the change would not have a "material" impact on the funds raised by the change.
