As mentioned above, the majority of buildings had isolated areas of debris specifically at the perimeter of the roofs, at the base of parapet walls, and in gutters. Debris was also visible at horizontal surfaces on some of the building facades including awnings. For some buildings, building facades facing the street were cleaned while the facades at the rear remained dirty. The figures above include these cases.

What actions did the DEP take at buildings where clean up of debris was necessary?

Notices were issued to building owner/manager identifying the results of the survey and the need to have an assessment of the debris performed. The specific procedures for the clean up activities would rely on the results of the assessment.

Who can perforin the assessment?

A survey and assessment for asbestos-containing material (ACM) must be performed by an individual who is certified by the DEP as an asbestos investigator. A list of certified investigators who agreed to have their telephone numbers posted on the DEP web page can be found at www.nvc.gov/dep. The certification status of asbestos investigators can be obtained by calling (718) 595-3693 between 8:00 a.m. and 4:00 p.m. Monday through Friday.

What are the credentials of a certified asbestos investigator?

Individuals who are certified as asbestos investigators have met the minimum education and experience requirements set forth in the NYC asbestos rules, successfully completed a New York State Department of Health approved training class, and passed a written DEP standardized examination.

What do the results of the debris assessment mean?

An assessment of the debris includes measuring the amount of debris and collection of bulk samples. Bulk samples must be sent to an accredited laboratory for analysis under a polarized light microscope (PLM). Samples found to contain greater than 1% asbestos are asbestos containing material (ACM) and must be handled by NYS DOL licensed contractors with DEP and NYSDOL certified workers.

How should the material be handled if it is not asbestos-containing material?

The NYC Department of Health has issued directives for proper clean up methods. HEPA vacuum and/or wet cleaning methods should be used for all debris clean up. Information is available at www.nvc.gov.

How has the DEP followed up on the notices to building owners/managers? Has the DEP monitored compliance with the notices?

The DEP continues to schedule site visits to identified buildings for follow-up. The DEP has received some information from building owners/managers regarding the assessments and clean
