Underground injection control.
Injection of any fluids to enhance recovery of oil or gas or for storage of liquid hydrocarbons is prohibited until such time as an application is made to do so. At that time the oil and gas conservation committee will promulgate rules and regulations that will conform with the underground injection control (UIC) program, chapter 173-218 WAC, which implement portions of the Safe Drinking Water Act (Public Law 93-523 as amended by Public Law 96-502).
