SCHERERVILLE, Ind. (AP) – State officials have cited Enbridge Energy LLC and a northwestern Indiana town for pollution violations stemming from the release of blue dye into local waterways.

The Indiana Department of Environmental Management said Thursday notices for violating federal water discharge standards have been sent to Enbridge and Schererville officials.

The Houston-based energy company had finished using blue dyed water to test a new 575,000-barrel oil storage tank for leaks last month when it sent that water into Schererville's wastewater treatment plant as part of an agreement with the town. 

But that plant wasn't able to remove the dye before the colored water was discharged into six to eight miles of the Little Calumet River's tributaries.

IDEM Commissioner Thomas Easterly tells The (Munster) Times (http://bit.ly/1zFwgKc ) “we're not going to do that again.''
