The Air Quality Management District (AQMD) says TXI Riverside Cement has made good progress in meeting the terms of a settlement stemming from air quality violations.
The company received a $1 million penalty, after air monitors in Rubidoux located near the plant recorded elevated levels of the toxic chemical hexavalent chromium.
AQMD Spokesman Sam Atwood says additional conditions will insure that TXI will reduce dust emissions near the plant.
“A requirement that the cement plant no longer bring in a so called cement clinker product to the facility, and in addition, remove all the existing clinker from the facility. The plant has completed that ahead of the schedule”, he said.
In October the AQMD Governing Board will consider amendments to existing rules that will require the complete enclosure of clinker material piles at all cement-manufacturing facilities.
