Aerocraft Heat Treating Company has finished construction of a new scaffolding on the street outside of its facility and has installed two of its own air quality samplers on the structure along with two samplers owned by the South Coast Air Quality Management District (SCAQMD). Following SCAQMD’s March 16, 2017 hearing, Aerocraft approached the City of Paramount for permission to build the scaffolding in the public right-of-way. This will raise the samplers above the height of Aerocraft’s perimeter wall thereby giving better accuracy with hexavalent chrome emission readings.
Last year, the City imposed a moratorium that prevents any new metal-related business from opening in Paramount and prohibits modifications to any existing business unless they are being done for air quality purposes. Since Aerocraft’s scaffolding was an example of the latter, aimed at mitigating emissions, the City worked closely with the company to expedite the permitting process.
Consequently, hexavalent chromium emissions readings are now being taken by the combined four monitors.
