DEQ Issues Deficiency Notice on Tintina Mine Permit Application

Thursday, December 15, 2016/Categories: Department of Environmental Quality/Tags:

HELENA – The Department of Environmental Quality today issued a response to Tintina Montana on the Black Butte Copper Project permit application. The response identifies deficiencies in the company’s September 2016 submittal of revisions and additional information.


“The company’s geochemical testing is still ongoing and the final results need to be incorporated into the application,” said DEQ director Tom Livers. “This testing and the hydrologic modeling are important aspects to determining completeness of the application and compliance with state law.”


Tintina Montana originally submitted its application for a mining permit in December 2015. DEQ responded to the application in March 2016, outlining the need for complete data on geochemical and hydrology information. DEQ’s most recent deficiency letter has numerous comments, largely due to parts of the application that were missing or incomplete in the original submittal.


“The September submittal has provided a more accurate indication of what is being proposed, as well as potential impacts and mitigations for those impacts. It is difficult to predict what the impacts of the mine will be until we receive all the information we need both to complete the permitting process and conduct an environmental analysis,” said Livers.


When the application is complete, DEQ will conduct an extensive environmental review and will prepare an Environmental Impact Statement with several opportunities for public comment.


The deficiency letter is posted to the DEQ’s website at:
