Cottonwood Creek stays impaired with no cleanup plan on file

Cottonwood Creek, threading through this stretch of Shale Deserts and Sedimentary Basins country, has been sitting on the EPA's impaired waters list without the cleanup plan regulators are supposed to write for it. That plan, a Total Maximum Daily Load, is meant to function as a pollutant budget: a ceiling on what can be discharged, and by whom, before the stream is considered back in compliance. Cottonwood Creek has none. The record doesn't specify which pollutant triggered the listing in the first place, which limits how much can be said about the underlying mechanism, but the practical effect is clear enough: there's no binding target steering recovery, just an open listing with nothing attached to it.

The contrast with nearby Short Draw is instructive. It's also listed as impaired, but it already has a completed TMDL on file, meaning whatever problem it's addressing is at least moving toward a fix. Cottonwood Creek has no such marker of progress.

Of the 19 facilities holding active discharge permits within ten miles, ten have racked up violations in the past four quarters, and one enforcement action has been taken, carrying $14,400 in penalties. None of those facilities has been tied specifically to Cottonwood Creek's impairment, and none currently rises to the EPA's most serious noncompliance tier. That's a mild sign, not a clean one; it means the known violators aren't the obvious culprits, not that the creek's problem has been ruled out or explained.

This is a landscape already defined by extremes in water: monsoon pulses that can flood a dry wash in minutes, followed by irrigation draws that pull streams down to a trickle. An impairment listing without a cleanup plan is easy to lose track of in that kind of setting, precisely because it doesn't announce itself. There's no fish kill, no visible plume, just a bureaucratic gap that persists quietly while the water keeps moving through it.
