Desert Mountain Energy is targeting a drilling area within 1.5 miles of the city's water supply wells, according to the city.
"The city's future water security depends on a safe supply of drinking water imported from [Red Gap Ranch]," the city said in a press release. "The city intends to vigilantly defend its water rights and any measures that threaten the integrity of the regional water supply and its water quality."
Desert Mountain Energy officials said Monday they were not contacted directly by the city or received official notification of the filing.
Officials said the company's drilling permits were duly and validly issued and Desert Mountain Energy is in full compliance with those permits. The company's news release also states that, to the best of its knowledge and belief, all previous work in the area has not and may not have had an impact on the Flagstaff or local area water supplies, and all existing wells are in compliance with Arizona laws and regulations.
A filing hearing is scheduled for Wednesday, according to a city spokesman.
