The environmental regulator in Texas is currently being re-evaluated as part of a regular process to determine if it's effective. The state agency that did the review came up with the conclusion "no, it isn't."

From what I've read, the regulating agency is widely seen as a rubber stamp operation for the petrochemical industry. Part of the codified process involves issuing a draft pollution permit before public input is even sought. Very backward from almost every other state I've studied.

Also interesting, there have been dozens and dozens of articles about massive methane discharges all around the state from various pipelines. Until recently, it's been impossible to see methane dumps in near-real-time. But now that there are satellites that can see the plumes, they're being detected all the time. Rather than flush the methane out of a pipeline into storage before maintenance, the pipeline companies have been just venting it into the atmosphere.

Amazingly, even though the methane dumps coincide exactly with the pipeline maintenance schedules, and the satellites document the plumes, the pipeline companies maintain their stance of, "Oh, yeah? Prove it."

My observation over the last 20 years is that while Texas is slowly getting greener, as the process progresses and technology improves, we're learning just how dirty it was to start with.
