Commissioner I have been asked by the City of New York’s Corporation
Counsel to require that all DEP employees who were involved in the
clean-up of Lower Manhattan following September 11* do all in then-
power to retain any and all written and electronic records relating to
this effort. The City is currently defending more than two thousand
claims arising from the September 11, 2001 terrorist attacks on the
World Trade Center and there is the potential for additional claims to
be filed in the future. As a result of this litigation, the City must
preserve all documents concerning the attacks and their aftermath,
including data in electronic form.
This means you may not delete, erase or otherwise destroy
any data relating to the attacks or the City’s response from your
computers, PDAs, agency electronic data systems and any personal
electronic equipment that you use in conjunction with your work. It is
impossible to describe every type of electronic data that you must
preserve. However, in general terms, if data may concern any aspect of
the events of September 11, 2001, or their aftermath, it must be
preserved. If you have any doubt about preservation, you must
preserve the data.
It is vital that all employees comply with this directive
immediately. If you have any questions, please contact Mark Hoffer,
DEP’s General Counsel at (718) 595-6528. Thank you for your
cooperation.
