Subject: Air Quality City Hall Update

In a previous report to the Commission on Sept.13, 2006, the City Engineer assessed the air quality concerns in the City Hall and proposed various recommendations. Most of these recommendations require additional routine maintenance that would result in a more positive impact on the indoor air quality of the building

These maintenance items included the coil cleaning and acid-washing of the HVAC units at the City Hall to remove any debris or mold that might be present. All of the municipal buildings have had the AC vents and duct system vacuumed for loose particles or dirt and debris. This process concluded with a disinfectant and sanitizer sprayed throughout the system to eliminate any previous odors and potential fungal growth that might be present.

In order to address the possible presence of a mold or fungal growth on any window sills in the City Hall, we replaced any defective weather stripping around the windows. Any sill that appeared to have significant water damage was replaced under normal maintenance procedures to prevent any accumulation of fungal material.

As indicated in the City Engineer’s report, in the event that any interior surface fungal growth was visible that resulted in elevated indoor fungal spore contractions, remediation work would be needed pursuant to the New York City Departments Health Guidelines and the II CRC S520 Mold Remediation Standard. We are pleased to state that we did not find any such evidence at the City Hall and therefore, this remediation work is not necessary at this point.

Therefore, as of this date, all air quality enhancement recommendations are in place and the project is complete.

Please feel free to contact me with any questions or concerns.
