Last week, one of the air samplers located outside Anaplex Corporation recorded a high level of hexavalent chromium. The South Coast Air Quality Management District (SCAQMD) reported the data on their website on October 25, 2018.
The City was contacted by SCAQMD about this high reading and told that, in this unique instance, SCAQMD did not implement a curtailment (i.e. shut down) of Anaplex’s operations. SCAQMD noted that the company was in the process of testing their newly-installed emissions control devices. Consequently, onsite source testing of equipment was being conducted. This testing required Anaplex to run its metal processing equipment non-stop in order to get baseline results. Since the equipment does not normally run all day, emissions were higher than normal.
On the same sampling day that the high emissions were recorded just outside of Anaplex, air samplers located both upwind and downwind of Anaplex recorded significantly reduced levels of hexavalent chromium.
The City is following these readings closely and will continue to update the community on further decisions by SCAQMD and Anaplex.
