The County of San Diego has released its annual Air Toxics "Hot Spots" report, highlighting pollution problems around the county.
"Motor vehicles, area sources, and natural sources are key contributors to the toxic air contaminants in San Diego County’s air, as they annually emit more than 62.5 million pounds into the atmosphere," concludes the study, noting the vast majority of air pollution is attributed to vehicle emissions.
While pollution from monitored "fixed sources" including "approximately 3,000 facilities including 1,750 diesel engine facilities, 368 auto body shops, 683 gasoline stations, and 117 dry cleaners" have dropped by nearly 23 percent since 2009, they still account for nearly 1.5 million pounds of contaminants being released annually.
Six facilities throughout the county have been singled out for implementation of "risk reduction plans" and biannual notification to residents of the dangers they pose. These include Pacific Ship Repair and National Steel & Shipbuilding in Barrio Logan, a neighborhood that has long grappled with environmental issues. These businesses, along with Naval Air Station North Island and the city of San Diego's Pump Station 2, which pushes 180 million gallons of wastewater daily toward a treatment plant in Point Loma, have successfully implemented plans.
The city's Miramar Landfill and GKN Chemtronics, an aerospace firm in El Cajon, still need to develop and implement risk-reduction plans of their own.
