Santa Barbara

Santa Barbara County Air Pollution Control District (SBAPCD)

California’s ambient air quality standards classified Santa Barbara County as nonattainment-transitional for ozone and nonattainment for PM10. Based on EPA standards, the county was designated unclassifiable/attainment for the 2008 federal 8-hour ozone and PM2.5 standards.

ERCs are available for five different pollutants:


Pollutant Significant Emission Rates
PM10 >15 tons/year
Carbon Monoxide >25 tons/year
All Nonattainment pollutants (except CO and PM10) >10 tons/year
All Attainment pollutants (except CO and PM10) >20 tons/year

To satisfy offset requirements, new or modified major facilities in nonattainment areas must obtain ERCs to satisfy the offset ratio requirements for proposed emission increases.  The offset ratio for nonattainment-transition area for ozone is 1.1. That means if 100 tpy of ROCs are emitted from a proposed new or modified major facility in an area classified as nonattainment-transitional for ozone, the facility must obtain 110 tpy of ERCs to offset the increase in ROC emissions.

In addition, emission reductions located in Ventura County and San Luis Obispo County may be considered for use at stationary sources in the District as stipulated in the California Health and Safety Code Section 40709.6. A minimum offset ratio of 1.5 to 1 shall apply to these reductions and a higher offset ratio may be established on a case-by-case determination by the SBCAPCD.
