Interpollutant Ratio Issues & Documentation

Goal of Interpollutant Evaluation: Establish the atmospheric exchange relationship for substitution of alternative pollutant or precursor reductions for required reductions of directly emitted particulateSJVAPCD Interpollutant Ratio ResultsSOx for PM ratio: 1.000 ton of SOx per ton of PM NOx for PM ratio: 2.629 tons of NOx per ton of PMThese ratios do not include adjustments for other regulatory requirements specified in provisions of District Rule 2201.

TOPIC Reference

1 Reason for using PM2.5 for establishing the substitution relationship between direct 

emitted carbon PM and secondary nitrate and sulfate PM: Consistency of relationship between secondary particulates and industrial direct carbon combustion emissions.

2008 PM2.5 Plan, Sections 3.3.2 through 3.4.2

2 Reason for using 4th Quarter analysis: Highest PM2.5 for all sites. DV Qtrs3 Reason for using analysis of southern SJV sites to apply to regional interpollutant 

ratio: Northern . site chemistry ratios are within the range of southern SJV ratios Peak ratiowill be protective for all SJV counties.

Q4 Model Pivot,Model-site chem,

Model-Daily Q4

4 Reason for using combined results of receptor and regional model: 

Receptor model provides breakdown of different carbon sources to isolate connection between industrial emissions and secondary PM.

2008 PM2.5 Plan, Appendix F

Regional model provides atmospheric information concerning the northern SJV not available from receptor analysis.

from other source types. Area of influence evaluation for contributing sources. 2008 PM2.5 Plan,

6 Most significant contributions of regional model: Scientific equilibrium methods for 

atmospheric chemistry projections for 2014. Receptor technique is limited to linear methods. 2008 PM2.5 Plan,

evaluation by J. W. Sweet February 2009Reflected in IPR County 2000-2009 worksheets

Fresno: Evaluation shows extremely strong urban signature (L1) for secondary sourcesKern: Evaluation shows a strong urban signature mixed with emissions from the surrounding industrial areas (average L1 and L2) for both carbon and secondary sourcesKings and Tulare: Prior evaluation has show a shared metropolitan contribution area (L2)

9 Reasons for using 2009 Interpollutant Ratio Projection:

2009 Interpollutant ratio is consistent with current emissions inventories 2008 PM2.5 PlanRegional modeling does not show a significant change in chemical relationships through 2014.

10 Reason for using SOx Interpollutant Ratio at 1.000: A minimum offset ratio is established 

as 1.000 to 1.000 consistent with prior District policy and procedure for interpollutant offsets. District Rule 2201
