South Coast Air Quality Management District (South Coast AQMD) is the regulatory agency responsible for improving air quality for areas spanning across Los Angeles, Orange County, Riverside and San Bernardino counties, including the Coachella Valley. More than 17 million people live in this area, which is nearly half the population of the entire state of California.
Within the South Coast AQMD region, any owner or operator conducting earth-moving activities of soil with applicable toxic air contaminants must comply with Rule 1466. The provisions in Rule 1466 include ambient PM10 monitoring, recordkeeping, dust control measures, notifications and signage.
TSI’s DustTrak™ Environmental Monitor is on the South Coast AQMD pre-approved list of PM10 monitoring instruments for Rule 1466. TSI was among the first companies to be accepted to the list of SCAQMD pre-approved monitors and still provides the most PM10 air monitoring options accepted among any manufacturer.
Below is a comparison of two popular TSI configurations on the SCAQMD pre-approved list.
