ST. LOUIS (AP) - Republican Senator Roy Blunt, of Missouri, is threatening to block President Barack Obama’s choice for Environmental Protection Agency administrator until plans are resolved for a long-stalled levee project in southeast Missouri.

Blunt and Democratic Missouri Senator Claire McCaskill expressed disappointment on Monday that the EPA and two other agencies missed a self-imposed March 15th deadline to establish a plan to move forward with the St. Johns Bayou and New Madrid Floodway project.

Construction to close a 1,500-foot gap in the levee was halted in 2007 due to technical problems with the project’s Environmental Impact Statement.

Obama announced his choice of Gina McCarthy as EPA chief earlier this month. Blunt says he’ll use a parliamentary procedure known as a hold to block the nomination until the levee issue is resolved.
