A federal audit has raised questions about the way a St. Louis social service agency spent a $2 million federal stimulus grant to retrofit diesel engines.

Grace Hill Settlement House received the grant in 2009 to install pollution-reducing technologies in vehicles like fire trucks, school buses and tugboats. It was part of the American Recovery and Reinvestment Act.

St. Louis may have missed out this week on a share of Race to the Top stimulus funds to improve public education, but it is a big winner on the health-care front. The federal government announced Thursday that it was extending through 2014 an unusual program that has provided about $25 million a year for funding area community health centers.
