Eastern Kern Air Pollution Control District (EKAPCD)
California’s ambient air quality standards classified Eastern Kern County as nonattainment for 1-hour and 8-hour ozone and PM10. Based on EPA standards, Eastern Kern was designated serious nonattainment for the 2008 8-hour ozone standard. In addition, serious nonattainment for PM10 include Kern River Valley and Cummings Valley.
ERCs are available for six different pollutants:
|Pollutant||Significant Emission Rates|
|Nitrogen oxides (NOx)||>25 tons/year|
|Reactive organic gases (ROG)||>25 tons/year|
|Sulfur oxides (SOx)||>27 tons/year|
|Carbon monoxide (CO)||>>100 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 extreme nonattainment area for ozone is 1.5. That means if 100 tpy of VOCs are emitted from a proposed new or modified major facility in the area classified as extreme nonattainment for ozone, the facility must obtain 150 tpy of ERCs to offset the increase in VOC emissions.
