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.Ìý 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 — seeÌýÌý. —Ìýchoose “Environmental Healthâ€� and then "Induced Seismicity from Oil and Gas Wastewater Injection" or go directly to —Ìý. The related report is also available at this link.

Poster Presentation
On August 24th, 2018, Rob Chase presented a poster on Damage Accumulation for a Two-Story Wood Frame Building in Sequences of Induced Earthquakes at the Forum for Infrastructure presented by SEG at Oklahoma State University. Rob’s work is focused on examining how potential seismic loss can change in a light-frame wood structure from multiple low magnitude shaking events.
