Summary of Efforts New!

The SCAQMD has undertaken unprecedented, extensive efforts to identify and reduce sources of hexavalent chromium in the City of Paramount. This Summary of Efforts in Paramount (PDF), summarizes the significant progress made and provides highlights of monitoring, enforcement, rule development, public outreach, and coordination efforts.


Background

In 2013, the South Coast Air Quality Management District (SCAQMD) received a series of metallic odor complaints from local community members in Paramount. In response to these complaints, the SCAQMD staff began conducting an investigation into local sources of emissions, including initiating a local air sampling study. The purpose of these activities was to determine the source of emissions and potential air pollution control strategies. Ambient monitoring of toxic metal emissions began in 2013 at two sites on Vermont Avenue and California Avenue. Based on the monitoring results, there were two metals of concern: nickel and hexavalent chromium.  In 2014 and 2015, SCAQMD worked with Carlton Forge Works to reduce metal particulate emissions from its grinding operation. Carlton Forge Works implemented a number of voluntary measures that substantially reduced nickel levels. Since these measures did not reduce hexavalent chromium levels, the SCAQMD needed additional data to understand the source of these emissions. In October 2016, as part of its ongoing investigation to identify and address sources of hexavalent chromium that may be impacting the nearby communities, SCAQMD staff deployed several monitors in the mostly industrial areas of the City of Paramount. Initial results showed elevated levels of hexavalent chromium upwind of Carlton Forge Works. Results of monitoring efforts, SCAQMD Town Hall Meetings, air monitoring and public health reports, and other related information are posted on this website.
