New rules for Texas injection wastewater well operators offer no relief to people impacted by more than 30 earthquakes that hit Azle, Reno and Springtown almost a year ago. Many buildings in the three small cities, 50 miles west of Dallas, Texas, suffered broken windows, cracked walls, damaged plumbing and foundations.
Seismic activity is not something the region is known for. It was only after deep injection disposal wells used to house fracking's toxic wastewater went into operation that the earthquakes started. There are several injection wells in the area — three of which some suspect to be the cause of the quakes due to their proximity to impacted neighborhoods and the volume of disposal operations.

“Injection raises the underground pressure and can effectively lubricate fault lines, weakening them and causing earthquakes, according to the U.S Geological Survey,” reports McClatchy Washington Bureau.
The Texas Railroad Commission, the agency that regulates the oil and gas industry, was met with public outcry after the first earthquake swarm. The commissioners acted fast (by the agency’s standards), coming up with new rules to address the situation released on Oct. 28.
The new rules require oil and gas companies to check local seismic data from the U.S. Geological Survey before opening a new waste disposal well. They also give the agency the power to change, suspend or revoke an injection operator’s permit if the commission determines the well is contributing to seismic activity.
