South Coast AQMD Issues Violations to Paramount Metal Facilities

The South Coast Air Quality Management District (South Coast AQMD) has recently taken action against two metal casting facilities in Paramount, California, by issuing Notices of Violations (NOVs) due to non-compliance with air quality regulations concerning hexavalent chromium emissions. This decision follows an investigation that revealed elevated levels of hexavalent chromium in air samples collected near these facilities.

Background of the Investigation

In September, air monitoring near the junction of Minnesota Avenue and other sites in Paramount indicated concentrations of hexavalent chromium that exceeded acceptable limits as prescribed by air quality regulations. Consequently, South Coast AQMD initiated a thorough investigation into local metal processing operations, focusing specifically on the facilities run by Pro Cast Industries and Fenico LLC. The latter operates at 15555 Minnesota Ave. and 7805 Madison St., respectively.

During the inspection, officials identified multiple violations pertaining to air quality standards. Notably, Pro Cast was cited for utilizing chromium-laden materials exceeding set emissions limits, and failing to properly manage and store chromium alloy scrap. Both facilities lacked essential permits required for operating metal processing equipment, were not conducting mandatory testing to verify compliance with hexavalent chromium emission standards, and failed to maintain cleanliness within designated areas surrounding their operations.

Potential Consequences of Violations

The NOVs issued can lead to substantial civil penalties for the businesses involved. To mitigate the situation, the facilities could opt for voluntary measures aimed at reducing emissions and ensuring compliance with air guidelines. If an amicable resolution is not achieved, South Coast AQMD has the authority to take further legal action against the facilities in question.

Ongoing Monitoring and Evaluation

In addition to the investigations, South Coast AQMD carried out mobile monitoring surveys that detected air toxic metals in the vicinity of the two facilities. While initial testing did not reveal elevated concentrations of hazardous metals like chromium, nickel, and others typically associated with metal processing activities, the agency continues to conduct on-site evaluations to locate potential sources of hexavalent chromium emissions.

Hexavalent chromium is recognized as a harmful air contaminant and a known carcinogen, and long-standing exposure can significantly increase the risk of developing lung cancer over time. Thus, the urgency for compliance with environmental regulations is paramount.

Historical Context

The South Coast AQMD has been actively monitoring air quality in and around Paramount since 2013 in response to widespread community concerns regarding air pollutants. Notably, the region's efforts intensified following investigations that were prompted by findings of high levels of not just hexavalent chromium, but also other toxic metals like nickel. Since 2016, continuous monitoring alongside strict enforcement measures has led to the identification of significant sources of hexavalent chromium in the vicinity, compelling operational changes at several local facilities, and resulting in marked reductions in contamination levels.

In 2019, the City of Paramount began to oversee routine air quality monitoring, maintaining vigilance over hexavalent chromium levels and reporting any concerning data back to South Coast AQMD. Their commitment has been showcased through the development of an accessible data dashboard for community members to track air quality metrics.

In conclusion, as investigations continue, it is crucial for regulatory bodies like South Coast AQMD to ensure compliance with air quality standards, to protect public health and the environment in and around Paramount.
