EPA asks for more tests before approving E-15

Posted:

WATERLOO (KWWL) -- The Environmental Protection Agency says it wants more tests to make sure car engines can handle higher concentrations of ethanol before they'll consider increasing the blend requirement from 10 percent to 15 percent.

The EPA said it won't make a decision until next year after all tests are complete.
