DRAFT ANSWERS FOLLOW-UP TO FEB 21 HOTLINE COMMITTEE
The following are some examples of questions raised by community
residents regarding environment, health, and quality of life In Lower
Manhattan
I. BUILDING RELATED ISSUES
A. Landlords/Enforcement
• How do I know my landlord had the HVAC (Heating, Ventilation
and Air Conditioning) system properly cleaned?
Contact your building owner and request the information. Building
owners were advised by DEP to change filters in ventilation
systems if they found debris after 9/11.
• Are there written protocols as to how to clean HVAC systems?
There are no standard protocols for cleaning HVAC systems.
However, if systems are dusty and have not been cleaned since
9/11 the City recommends that the building owner/management
company change filters on the system and use a HEPA vacuum to
clean the system.
• What can I do about buildings that have not been cleaned yet
(roofs, window sills, fire escapes, lobbies, hallways)? What
agency enforces building cleaning?
The Call Center will take information from the Individual and DEP
will respond. The requirements for cleaning vary based on the
hazard assessment
• My landlord had the building cleaned back in September but
he has not done anything since, whom can I call to make sure
he continues to clean?
The City has issued a new Fact Sheet on cleaning procedures
reminding people in lower Manhattan to continue frequent cleaning.
This is available on the website ut: If you do not have access to
a computer, the Call Center can take your name and address and
send you information In the mall. In addition, the Call Center can
also take your information and forward your concern to DEP.
