At a Glance, PDF page 3:
"EPA Region 5 had the authority and sufficient information to issue a SDWA Section 1431 emergency order to protect Flint residents from lead-contaminated water as early as June 2015."
"EPA Region 5 did not issue an emergency order because the region concluded the state’s actions were a jurisdictional bar preventing the EPA from issuing a SDWA Section 1431 emergency order."
"The EPA Administrator subsequently directed OECA to issue an emergency order on January 21, 2016."

Report printed page 5, section 'EPA Region 5 Had Sufficient Information and the Authority to Issue an Emergency Order in June 2015, but Did Not':
"By June 2015, EPA Region 5 had information that the city of Flint exceeded the lead level at which corrosion control is required, and that Flint was not using a corrosion inhibitor."
"EPA Region 5 also had information that at least four homes had concentrations of lead in household drinking water above the action level of 15 parts per billion."
