Description: The purpose of this ordinance is “to safeguard the Casper aquifer wells and springs which provide 60% of the City’s municipal water.” To accomplish this purpose, Laramie creates an aquifer protection overlay zone (APO zone) within which a total of 36 activities are prohibited, including the use of dry cleaning solvents. The ordinance provides for additional restrictions around “vulnerable features” in the aquifer that could increase potential harm from contamination.
