Longmont, Colorado, has reportedly prohibited the use of hydraulic fracturing to extract oil, gas and other hydrocarbons from drilling operations within the city limits. Fifty-nine percent of voters approved a citizens’ initiative amending the City of Longmont Home Rule Charter. In additional to banning hydraulic fracturing, the amendment prohibits open storage pits or disposal of solid or liquid wastes created in connection with hydraulic fracturing, including flowback and produced wastewater and brine. According to news reports, Colorado is expected to sue the city alleging that the ban is preempted by state law and citing the state Oil and Gas Commission as the proper regulator of oil and gas extractive activities in the state.
