Peter said EPA already has a contractor lined up to start the work and there are funds available to support it. Submitting our reports and plans for peer review would help gain credibility. A recommendation was made that our critics can select panelists. Peer review always adds more time to the process. Peter Grevatt will provide examples of how the process worked in other situations. This process would be useful if it can be made to work. Need to decide what would be peer-reviewed, whole approach or single issues

4. Man for Pilot Clean-up The plan is to sample-clean-sample using HEPA vacuuming, regular vacuuming, and wet washing. Will start with the broader COC list Will continue to work through NYC for list of buildings and accessibility. Recommendation made that pilot effort try to evaluate dust exposure to an individual while cleaning. There were 10 buildings identified as untouched in the Greenwich Street/Cedar Street/Liberty Street and Church Street area. NYC’s legal department will coordinate with EPA’s Office of Regional Counsel regarding this information. The exteriors need to be cleaned before the Pilot clean-up can be done inside the buildings. Questions will be asked about what the exposure risk was to those who already performed self-cleaning. OSHA’s personal monitoring data collected during earlier cleaning activities shows very low levels. OSHA will share this data with the workgroup. ATSDR will be providing a report to the workgroup in May.

5. Status of NYCDEP Efforts for Building Clean-up 258 buildings have been sampled. Bulk and air samples have been taken. Report shared with group. There is existing data available for NYC-owned or leased buildings. Bids are due next week for the air monitoring contracts associated with the exterior building clean-ups. NYC will provide a map of the clean-up area. All buildings in the area are being cleaned regardless of contamination levels. Some building owners did their own exterior cleaning. NYC will visually inspect these buildings prior to cleaning or removing them from the list. • The workgroup needs to come up with a communication plan to respond to the public when asked about public exposure during clean-up activities.

.Note: All data supplied to the workgroup at this time is for internal use only.
