• EPA withdraws a proposed rule to reduce wastewater pollution from slaughterhouses.
  • EPA will seek to cut federal protections for wetlands.
  • USDA will prepare an environmental impact statement for repealing the Roadless Rule that shields national forests and grasslands from logging and road building.
  • New Mexico and Texas agree to Rio Grande lawsuit settlement.
  • CBO reports on U.S. agriculture’s greenhouse gas emissions.
  • EPA proposes allowing Wyoming to manage its own coal-waste program.
  • Interior Department completes work on soil burn severity assessment for a large fire north of the Grand Canyon.

10 Percent: Share of U.S. greenhouse gas emissions generated by agriculture, according to a Congressional Budget Office report. The main pollutants in this total are nitrous oxide, a byproduct of fertilizer, and methane, which comes from livestock manure and cow burps.

$21 Million: Research and development funding from the Department of Energy for hydropower projects. The largest portion ($7.1 million) is to investigate the feasibility of a massive pumped storage hydropower project proposed for Navajo Nation land. Pumped storage toggles water between a lower and upper reservoir, a system that functions like a battery. New Mexico State University is the co-investigator for Carrizo Four Corners, the 1,500-megawatt pumped storage project that could provide 70 hours of energy storage, far more than the several hours of storage provided by the largest lithium-ion batteries.

Slaughterhouse Waste
The Environmental Protection Agency will not strengthen wastewater discharge rules for meat and poultry producers. The rules were proposed during the Biden administration.

To justify the action, the agency cited its desire to lower food prices and reduce industry operating costs.

The Biden-era rule intended to reduce the volume of pollutants that enter waterways from some 3,879 slaughterhouses nationally. Those pollutants include nitrogen, phosphorus, organic matter, fecal coliform, and grease. They contribute to harmful algal blooms and low-oxygen dead zones in rivers, lakes, and coastal ecosystems.

A Narrow Wetlands Definition
The EPA is preparing to release a rule by the end of the year that would shrink the number of wetlands with federal protection under the Clean Water Act, E&E News reports.

According to a slide presentation seen by E&E, the agency “would regulate wetlands only if they meet a two-part test: They would need to contain surface water throughout the ‘wet season,’ and they would need to be abutting and touching a river, stream or other waterbody that also flows throughout the wet season.”

The changes are in response to a 2023 Supreme Court ruling that provided narrower, but undefined criteria for determining which water bodies have federal protection.

Rio Grande Settlement
By signing a settlement agreement, New Mexico, Texas, and the Justice Department are closer to ending a long-running dispute over water rights from the Rio Grande and the groundwater pumping that affects river flows, Inside Climate News reports.

“The settlement package includes new formulas to calculate how much water each entity is owed; an agreement for New Mexico to reduce groundwater depletion, and changes to the operating manual for the Bureau of Reclamation’s Rio Grande Project.”

Roadless Rule
The U.S. Department of Agriculture is pushing ahead with its attempt to undo a 24-year-old rule that prevents logging and road building in “roadless” areas of national forests and grasslands.

Rescinding the Roadless Rule, which was adopted in the last month of the Clinton administration, will affect more than 44 million acres, mostly in 10 western states.

The department will prepare an environmental impact statement for its intent to repeal the rule. It argues that more local control over land management decisions are needed.

Comments are due September 19. Submit them via www.regulations.gov using docket number FS-2025-0001.

Dragon Bravo Fire Burn Severity
An Interior Department team completed an evaluation of the soil burn severity of the Dragon Bravo Fire, which has burned across more than 149,000 acres north of the Grand Canyon.

The fire severely burned the soils on just over 2 percent of the acres. Another 26 percent was moderately burned. The most severe burns cook the soil, which increases surface runoff after storms. Erosion and downstream floods can be the result.

Emergency Alert System Improvements
The Federal Communication Commission is beginning the process to assess and potentially upgrade the nation’s emergency alert systems that local agencies use to inform residents about natural hazards like floods and fires.

The commission is taking public comments through September 25. Submit them here using docket number 25-224.

Wyoming Coal Waste
The EPA wants to grant more states the authority to regulate waste products from burning coal for electricity. Wyoming is the latest state to seek this power, called primacy.

The agency is proposing to approve Wyoming’s bid to oversee its coal ash permitting program.

A public meeting will be held October 30. Public comments on the proposed approval are due November 3. Details are in the above link.

Three states currently have primacy. North Dakota’s application is being reviewed.
