HVAC system will be evaluated as a whole. In cases where cleaning is requested for an individual residential unit, portions ofthe HVAC system dedicated to that unit will be evaluated. Whv is there a distinction bemg made between those cases where cleaning is requested for an individual residential unit andfor awhole building. When onlyafractionofthebuilding’sHVAC system is cleaned, it would seem likely that the uncleaned (contaminated) section ofthe building’s HVAC system would quickly contarnmate the other previously cleaned section. (Ifthis were not the case, it implies that contaminants once in the HVAC system do not migrate, hence there is no problem with any part ofthe system and we shouldn’t bother to clean it.) No residential or common space shall be cleaned until the HVAC system has been evaluated and cleaned as necessary.
The Monitoring contractor shall inspect HVAC systems or portions thereof cleaned to verify cleanliness.
HVAC assessments, cleaning, and cleanliness inspections shall be conducted in accordance with the National Air Duct Cleaners Association (NADCA) General Specification for the Cleaning of Commercial Heating, Ventilating and Air Conditioning Systems and the NADCA Assessment, Cleaning and Restoration Standard (ACR 2002). Qualified personnel shall perform the HVAC evaluation and cleanliness inspections. At a minimum such personnel shall have an understanding of HVAC system design and experience in utilizing accepted indoor environmental sampling practices, current industry HVAC cleaning procedures, and applicable industry standards.
Deliverables
The Proj ect Monitor shall review all deliverables prior to submission to EPA. The review shall assure that each deliverable is accurate and complete, technically sound, and free of clerical error. The contractor should document findings and report the results ofthe initial evaluation and the evaluation after the clean up.
The Project Monitor shall record if the HVAC systems have been evaluated and cleaned subsequent to September 11,2001. Ifyes, when and by whom. This information shall be provided via F2L or an agreed upon alternative electronic format or website approved by EPA within 24 hours of activity.
6. In the event that mold is observed in a residence during the pre-cleaning inspection, the Monitoring Contractor will contact the NYCDOH and EPA. Is any amount ofrnold sufficient to tiigger this contact? Will clean up procede irregardless offmding mold? (Apd what will NYCDQH and EPA do about it?)
