Class II UIC Well Regulations Dataset
The Regulatory Actions group of the CCIS recently finished a compilation of statutes and regulations regarding Class II UIC wells relevant to managing induced seismicity from oil and gas wastewater disposal.听 Accompanying this dataset is a report comparing the relevant regulations of EPA and the seven surveyed states (AR, CO, KS, OH, OK, PA, TX).
The publicly accessible, interactive dataset, including citations and text of the relevant law, is posted on the LawAtlas website 鈥� see听听. 鈥斕齝hoose 鈥淓nvironmental Health鈥� and then "Induced Seismicity from Oil and Gas Wastewater Injection" or go directly to 鈥斕�. The related report is also available at this link.
