Contacted by email Wednesday, EPA Region 8 spokesman Rich Mylott would not respond to the governor's remarks. He also did not answer a question about the EPA's plans for peer review of the report.
He reiterated part of a prepared statement the EPA released to reporters who asked about the extension.
"The Agency will take into account new data, further stakeholder input, and public comment as it continues to review the status of the Pavillion investigation and considers options for moving forward," Mylott wrote, adding that he had no more information to provide.
The comment period began on Dec. 14, 2011, and was extended twice last year.
The first extension was last March, after the state and EPA agreed to collaborate on further groundwater testing. The second extension was in October, soon after those new test results — which were similar to the results of EPA's earlier testing — came out.
