DUST CONTROL

 

CONSTRUCTION DUST

Demolition activities, construction traffic, site preparation and foundation work, and material stockpiles all have potential to generate dust during the demolition, remediation, and construction phases of the project. Demolition and remediation at the site started in mid-April 2009.

In the months prior to demolition, lead, asbestos and other regulated materials were removed to minimize site contamination during the demolition process.  During the several months of demolition, components of the building are being recycled or disposed.  Following building removal, the soils for the site will be exposed for remediation, which will primarily involve shallow excavations associated with soil treatment processes, minimizing the likelihood of dust being blown to offsite locations from the exposed soils.

 

NO ASBESTOS DUST

Asbestos, considered a hazardous material, naturally occurs in serpentine rock, which can be found in certain pockets of San Francisco. Because this project site does not contain serpentine rock, asbestos-containing dust will NOT be generated. In addition, utmost care in dust control will be taken, as described below.

 

DUST CONTROL

The Dust Control Plan for demolition activities has been prepared by MACTEC Engineering and Consulting, Inc. (MACTEC) in accordance with the requirements of the permit process established in Bay Area Air Quality Management District (BAAQMD) regulations and in coordination with the San Francisco Department of Public Health (SFDPH).

While the dusts from the site do not contain naturally-occurring asbestos, utmost care in dust control are being taken through dust control Best Management Practices (BMPs). BMPS are required to be implemented throughout the project, include wetting and seeding unpaved or inactive areas, minimizing activity during periods of high wind, sweeping paved areas, covering trucks, etc. These dust control measures are intended to achieve a goal of no visible dust emissions associated with soil disturbance or excavation, to the extent required by BAAQMD. To ensure effectiveness of the control activities, dust monitors are set up in downwind areas.  Real time dust monitoring will be conducted to ensure dust concentrations do not exceed nuisance levels, determined by BAAQMD, at the site boundaries.
