- Hinson Voted to Let Major Toxic Air Polluters Escape the Strictest Controls in May 2025.

On July 3, 2025, Hinson voted yes as the House passed the final One Big Beautiful Bill Act 218 to 214, after voting for the House version, which passed 215 to 214, so it would have failed without her vote. The law includes a RESCISSION OF FUNDING FOR DIESEL EMISSIONS REDUCTIONS, a RESCISSION OF FUNDING TO ADDRESS AIR POLLUTION AT SCHOOLS and a RESCISSION OF FUNDING FOR ENVIRONMENTAL AND CLIMATE JUSTICE BLOCK GRANTS, taking back money Congress had set aside in 2022 that had not yet been spent.

What the Pollution Votes Ashley Hinson Cast Mean for Iowa's Water
- Nitrate in drinking water. In Iowa in 2025, nitrate contaminant levels above the EPA limit was the most common health-based standard violated by public water systems, and the 36 violations occurred at 13 systems and impacted a total of 2,479 customers, twice as many violations as in 2024, the Iowa Department of Natural Resources reported.

The PERMIT Act Hinson voted for would exempt stormwater from agricultural lands from Clean Water Act permits.
