Quick Summary

Secret documents from 9/11-related records reveal that New York City's Department of Environmental Protection (DEP) was convicted of two federal environmental crimes, including one felony, just weeks before the September 11 attacks in 2001. The DEP admitted to discharging mercury-contaminated water into a tributary and violating the Toxic Substances Control Act by using PCB-contaminated machines at a water supply facility, receiving probation until 2009 as part of their sentence. Later, in 2006, the DEP was found to have violated its probation for failing to maintain emergency electrical systems during the August 2003 blackout, leading to the discharge of approximately 30 million gallons of untreated sewage into the East River.

Story summary

In August 2001, just weeks before the September 11, 2001 attacks, the New York City Department of Environmental Protection (DEP) was convicted of federal environmental crimes under Mayor Rudy Giuliani's administration. The DEP admitted to discharging mercury-contaminated water into an upstate New York reservoir in violation of the Clean Water Act and unauthorized use of PCB-contaminated machines at a water supply facility, violating the Toxic Substances Control Act. These admissions were part of 170,000 secret documents related to 9/11 that Mayor Zohran Mamdani’s administration recently released. Andrew Carboy, representing the advocacy group 911 Health Watch, called this revelation "deeply disturbing," highlighting the DEP's failure to comply with critical environmental laws while entrusted with protecting New York City residents' air and water quality.

🔮 Gov. Kathy Hochul will raise New Yorkers’ taxes to fulfill Mayor Zohran Mamdani’s socialist agenda if she’s re-elected next week, her GOP opponent Bruce Blakeman warned.
🔮 A spokesperson for the Justice Department said, “The Department takes allegations of antisemitism seriously and is committed to enforcing federal civil rights laws that protect students from discrimination.” The city DOE and Mayor Zohran Mamdani’s office didn’t immediately respond to a request for comment.
🔮 “New York needs an attorney general who will put public safety over politics and make sure New York State is one of the most prosperous, best places to live in the country,” Teixeira added.
🔮 The Transport Workers Union of America, whose local members include roughly 40,000 city subway and bus workers toiling under an MTA contract that lapsed in May, began airing the scathing spots Friday, a day before early voting opened
🔮 Critics – including President Trump — immediately called for her to step away, saying she was too political, biased and unethical to fairly investigate the case. Norman Siegel, a longtime civil rights lawyer, said James is doing the right thing, adding that her taking the case would be like a police commissioner commenting on police misconduct cases before a probe is finished.
🔮 The folky tunes of an extremely rare piano will once again sound in Manhattan Friday — nearly a century after Mayor Fiorello LaGuardia banned the instruments from the city streets.
🔮 Your name will still appear in the poll pads and you could still vote on the machines,” said BOE spokesman Vincent Ignizio.
🔮 The nine-member Public Design Commission was supposed to only review how the new casino and its grounds were supposed to look and accommodate the public — but critics at the meeting attacked the project by Mets owner Steve Cohen over objections to gambling and how it would affect the area.
🔮 The country’s teachers unions are opposed to the program, claiming it will somehow siphon taxpayer dollars from public schools — even though backers such as Dem New York Gov. Kathy Hochul have dismissed the notion.
🔮 Some members of the Real Estate Board of New York made max donations to the Friends of Kathy Hochul and the Democratic Party — a move that may aim to give them influence with the governor but may ultimately be fueling policies that are hurting their bottom lines, strategists and Republicans said.

Narrative

“The New York City Department of Environmental Protection is entrusted with performing critical functions for all New Yorkers, including the provision of drinking water and the prevention of water pollution,” Garcia said at the time, noting the agency’s admission in court was “an important milestone in achieving the goal of this federal prosecution: to ensure that DEP complies with all applicable environmental and worker safety laws while carrying out its responsibilities.” Andrew Carboy, a pro bono lawyer for the advocacy group 911 Health Watch — which sued the city to get it to release the long-hidden documents — said the DEP’s prior conviction was “deeply disturbing.”
