Plans to Improve Air Quality in Muscoy

San Bernardino

The County of San Bernardino is moving beyond the requirements of state regulators to improve air quality in parts of the county by implementing a new plan targeting emissions from heavy-duty diesel trucks, the main source of air pollution in the community, warehouses, the BNSF railyard and the Omnitrans bus yard in San Bernardino.   The plan is aimed at reducing air pollution in the community of Muscoy and other unincorporated areas in the county near homes, schools and public places within the unincorporated part of the county.  Identified as the Community Emissions Reduction Plan, it is designed to reduce air pollutants like nitrogen oxides and particulate matter through monitoring key sources of pollution like heavy duty trucks, concrete and asphalt batch plants in addition to rail and bus yards and warehouses.  The county will measure the plan’s success against predetermined goals that call for a 10 percent reduction in nitrogen oxides and particulate matter by 2024 that would increase to a 21 reduction in nitrogen oxides and a 15 percent reduction in particulate matter by 2029. According to officials, when these goals are combined with state-mandated reductions, the community may potentially experience more than a 50 percent reduction in nitrogen oxides and 70 percent reduction in diesel particulate matter in the next few years.  Officials acknowledge the ever-expanding warehouse industry coupled with the associated increase in the number of semi-trucks that park and idle in the region is contributing to a degradation in air quality.  The Community Emissions Reduction Plan is the roadmap to partial fulfillment of AB 617, passed by the California legislature in 2017, which required local air districts (including the South Coast Air Quality Management District) to address air quality in communities disproportionately impacted by local sources of air pollution including trucks, trains, ships and industrial facilities. Muscoy is one of three communities selected for the initiative.
