The city will hand over the names of NYPD employees who helped at the cleanup at Ground Zero -- and with consent, their health statuses -- following pressure from the police union.
Since November, the union had been asking for their records to be sent to Mount Sinai Medical Center in order to determine how many workers developed cancer.
The info will help the federal government to determine next month whether cancer should be covered in the 9/11 health act, which covers first responders who developed illnesses from working at Ground Zero.
"Since federal and state laws prevent us from disclosing the names of those who have reported that they have cancer or other conditions without their permission, we are developing a process to ask all of those individuals if they will authorize the release of their names," Deputy Mayor Cas Holloway said in a statement. "We are committed to working with Mt. Sinai to share this information as quickly as possible."
