The hearing has passed
The Watch stands.

The decision was due July 21. Instead: a public hearing — first set for October, then moved up to September 14 at the applicant’s request — and a ruling due by November 23. A $165B question for one desert county, on a schedule that keeps moving. The clock above always shows the next date that matters. Until the ruling, and after, this is the public watch on how it’s being made.
