New York's 9/11 Air Records and a California Hydrant Bill — September 8, 2026

Today's news is less about smoke on the ground and more about the paperwork around it: what a city knew about its air, who is liable when hydrants run dry, and what people are allowed to bet on.

New York City opens its 9/11 air-quality files

New York City released about 170,000 pages of previously undisclosed records on Tuesday covering air quality and health risks after the September 11, 2001 attacks. As CNN reports, the records include contamination data gathered by local environmental agencies in the days after the attacks, along with air-quality reports and internal communications showing officials were concerned about the air and about the city's potential legal liability.

City Corporation Counsel Steven Banks said in a briefing that there are clear indications the city knew there was a problem with air quality, and that records demonstrating it had gone unreleased for years, according to the New York Daily News. NBC10 Boston reports that one undated internal letter to a deputy mayor listed potential grounds for lawsuits against the city, including health advisories that brought people back to the area too soon.

The release comes days before the 25th anniversary of the attacks and settles two Freedom of Information Law lawsuits. As amNewYork reports, the settlement sets up a yearlong process for further disclosures, with monthly meetings between the parties over the next 12 months.

A California bill on water agencies and wildfire lawsuits

California legislators have passed Senate Bill 1153, which would clarify that public water agencies have no duty to design, build or maintain a water system for wildfire defense or suppression, and that a loss of water supply or pressure during a wildfire is not a substantial cause of fire damages. The bill is awaiting Governor Gavin Newsom's signature.

As the Los Angeles Times reports, the legislation arrives while the city of Los Angeles and the Los Angeles Department of Water and Power face lawsuits from residents who say the city failed to ensure adequate water to fight the Palisades fire.

A push to ban betting on wildfires

Lawmakers have asked federal regulators to ban prediction-market betting on wildfires, citing fears that the practice could encourage arson and divide communities. The Mercury News reports that during the January 2025 Los Angeles fires — which destroyed more than 16,000 structures and killed 31 people — the prediction market Polymarket took in more than $1.2 million in bets on questions like how many acres would burn and which neighborhoods would be consumed.

A study on the roadless rule and fire

The Trump administration has pushed to rescind protections on millions of acres of Forest Service land. The Missoulian reports that a new analysis may undercut the argument that the roadless rule has increased fires on those lands.
