There's some interesting history here [1].
Anne Gorsuch Burford was appointed by Reagan to head the EPA. She beleived federal regulations had become too onerous and the power of the administrative state had become too large. It was her mission to roll back environmental protections and gut the agency through reorganizations and layoffs.
This did not go well. She ultimately resigned over a scandal where she withheld funds to help clean up a site to hurt a Senate campaign and lied about it. The Reagan administration eventually discovered the lie and I believe she resigned to avoid proseecution.
The EPA under Reagan tried to limit clean air responsibilities by narrowly scoping what a "source" of static pollution is. The Natural Resources Defence Council ("NRDC") sued, in a case called Natural Resources Defence Council v. Gorsuch [2].
Interestingly, the trial court judge was future Supreme Court judge Ruth Bader Ginsburg. The Court ruled against the EPA. That case was appealed to the Supreme Court as Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc [3].
The Supreme Court reversed this decision and said that the EPA had the broad authority to define what a "source" was as policy and this become the basis for what we now called (or used to call) "Chevron deference". It's worth noting that SCOTUS at the time made what was then a pro-corporate and anti-environmental decision.
Former EPA Anne Gorsuch Burford's son is Neil Gorsuch, current Supreme Court justice who voted to overturn Chevron deference and essentially avenge his mother, continuing her anti-government legacy.
