Lucas Fire Evacuations in Lake County and New York's 9/11 Air Files — September 11, 2026

Two stories today sit at opposite ends of the same timeline. In Northern California, a grass fire is still spreading and people are being asked to leave. In New York, the city is releasing documents about air that people breathed twenty-five years ago.

Lucas Fire grows fast on the Lake-Mendocino line

Cal Fire began fighting the Lucas Fire shortly after 9 a.m. on Thursday, September 10, in a remote area near the Lake and Mendocino county border. As the Santa Rosa Press Democrat reports, the fire moved through grass and oak and grew from 10 acres to 400 acres by 4 p.m., jumping the containment lines crews had built early in the fight.

The Lake County Sheriff's Office issued an evacuation order just before 4 p.m. covering Elk Mountain, Bear Peak, Hog Point and Hells Peak, with evacuation warnings for several nearby zones. The Mendocino County Sheriff's Office issued a warning for the Potter Valley area around the same time. Cal Fire said the cause was under investigation but confirmed lightning was recorded in the area that morning.

A day earlier, the Steele Fire ignited in a burn scar south of Lake Berryessa in Napa County. Crews halted its advance the same afternoon, and Cal Fire mapped it at 50 acres with 30% containment on Thursday. Hot, dry, windy conditions have been setting up smaller fires across Northern California in recent days, which is the kind of pattern worth watching your local air readings for even when no single fire is large.

New York City releases 170,000 pages on post-9/11 air quality

New York Mayor Zohran Mamdani accused previous city leaders of lying about air-quality safety after the September 11 attacks, and announced the release of more than 170,000 pages of documents related to the air around the site of the fallen towers. As reported by Arkansas Online, the records had been stored in 68 boxes in a city office and kept from public view for more than two decades.

In the weeks and months after the attacks, city and federal officials reassured New Yorkers that the air around ground zero was safe to breathe. The documents describe several instances in which carcinogens were present in the area for months afterward. A November 2001 audit confirmed elevated levels of benzene near ground zero that month and higher concentrations of ambient asbestos on Staten Island. Asbestos was still being found near a building less than a mile from the World Trade Center ten months after the attacks.

Sacramento's air is the cleanest it has been in 25 years

Sacramento's summers were once known for smog, and officials now say the region's air quality is the best it has been in a quarter century. CBS News reports that pollution levels have dropped 30% over the last 25 years even as the population grew, and that the region now meets the 2008 federal air-quality standards.

The Spare the Air day count tells the story plainly. There were 17 of them in each of 2016 and 2017, and 20 in 2018. Last year there were two, and so far this year there has been one. Sacramento's Air Quality District, which is marking its 30th anniversary, credits a mix of large and small efforts: replacing diesel school buses with zero-emission vehicles, swapping gas lawn tools for electric ones, converting wood-burning fireplaces, and more people driving electric cars. A decade ago the region ranked fifth worst in the nation for pollution and faced federal sanctions.

Congress moves on the Fix Our Forests Act

A bipartisan bill aimed at preventing catastrophic wildfires is close to passing, and it has split the environmental movement. The Los Angeles Times reports that the Fix Our Forests Act would speed up forest management projects on public and tribal lands by reducing regulatory and legal hurdles, and it has broad support among Republicans and the timber industry.

The Sierra Club and the Center for Biological Diversity oppose the bill, arguing that limiting environmental review and litigation would let timber companies log heavily instead of thinning gently. Some Southern California groups worry the bill would allow land managers to approve projects that harm local shrublands, which relate to fire very differently than forests do. The Nature Conservancy and other groups support it, citing the threat that increasingly severe wildfires pose to communities and ecosystems.
