Mayor Zohran Mamdani 's administration released on Wednesday another 40,000 documents related to the Sept. 11, 2001, terrorist attacks, adding to a growing public archive of records that survivors and first responders spent years fighting to access.

The latest release brings the total to more than 60,000 documents spanning over 200,000 pages, according to 9/11 Health Watch , the advocacy group whose legal battle with the city helped secure their release.

The documents are available through the city's September 11th records portal , launched in September as part of a settlement of two Freedom of Information Law lawsuits seeking records about air quality, health risks, and government decisions following the attacks 25 years ago.

"Our commitment to honoring the victims of the horrific terror attacks of Sept. 11 and delivering accountability and transparency to survivors cannot begin or end on the anniversary," Mamdani said in a statement Wednesday.

The new batch follows the administration's initial release of more than 170,000 pages , which included internal city records raising questions about what officials knew about hazardous conditions in Lower Manhattan as residents, workers and first responders returned to the area.

Among those records was a February 2002 memo warning that the city might not be adequately informing the public about health risks, along with a May 2002 note indicating that an official involved in cleanup discussions sought to avoid using the word “risk” in letters concerning the effort.

9/11 Health Watch said its review of the initial records found evidence that government officials recognized the extent of the air-quality hazards but failed to adequately change course.

"What we have seen after a review of the first tranche of 170,000 released documents is a disturbing record that, even when the problems and hazards were realized, the City, the State and the Federal government did not change course and deal with them head-on," said Benjamin Chevat, the group's executive director, in a statement Wednesday.

The group said its attorneys have begun examining the newly released documents and will report any additional findings. The latest disclosure is the second installment under the city's settlement with 9/11 Health Watch, which calls for additional records to be made public over the coming months. A separate, City Council-mandated Department of Investigation inquiry is also examining what city officials knew about post-9/11 air quality, when they knew it, and why certain decisions were made About the Author Conversations Profile All comments are subject to our Community Guidelines .
