NYC 9/11 Public Portal Document

Notes from 11/26/02 meeting of EPA/NYCDEP regarding HVACs

Existing/Already Inspected:

1. EPA reyiews HVAC eyaluations for completeness 2. EPA/NYCDEP reyiew building information where ayailable (NYC drafting letter to send to building owners to get reports) 3. Ray and Krish consult to make determination on appropriate course of action 4. If cleaning is needed, Krish contacts quad cleaning contract to determine if cleaning can be done by unit cost pricing by existing cleaning contractor 5. If cleaning contract cannot do cleaning, NYC determines another way to get cleaning done

Exhaust Systems Issues:

1. If it is determined cleaning is necessary, EPA/NYC will operate under the principle we will do the best we can where we haye limited access - we will coordinate with building management to see if we can get in to do the cleaning, and will clean within those apartments and will clean fans on top but may not be able to clean entire risers due to problems gaining access 2. EPA will reyiew monitoring data from apartments in the building that are part of the cleaning and/or testing program 3. In cases where there may be conflicting information between the building owner’s report and the monitoring contractor’s HVAC eyaluation, Ray and Krish will consult and determine the appropriate course of action.

Approach for the Present

(Present - Interim between eyaluations already conducted and the completion of the actiyities outlined in Step 1 and Step 2 below.)

1. In quads B, C and D the subcontractors haye been approyed 2. Contractors need to submit all outstanding reports to EPA 3. Once EPA has receiyed satisfactory reports, eyaluations can be restarted at a rate of 5 per quad, once 5 are completed the contractors should stop conducting eyaluations and complete the reports for submittal to EPA. 4. EPA will proyide to NYCDEP an update on the whole building request status including information on eyaluations completed, reports receiyed, and recommendations made by the contractor 5. NYCDEP will follow-up with building owners to get reports on work they did particularly in Quad D. 6. EPA and NYCDEP will monitor Cole’s subcontract for effectiyeness and producing reports of inspections.
