Study Purpose
Update the SO2 emission milestones for the 309 States
Non-utility source focus Milestone sources >100 tpy SO2 in
2004 at the facility-level

Methods Summary
Starting point – 2018 SSJF-sponsored emission projections
MS Excel files posted on SSJF/ projections site» 2002 emissions» Growth and control factors» Equation to estimate 2018 emissions
Revised base year emissions to 2004 values where needed

Petroleum Refining
Retirement/replacement algorithm for SO2 only affects FCCU and industrial boiler emissions
FCCU emissions not represented for 7 of 11 refineries
Pechan allocated SO2 emissions to FCCUs and revised projections

Fuel Combustion
Previous Approach» SCC-specific growth indicators from
EGAS (AEO energy forecasts). Major limitation is inventory SCC is often generic Industrial, Commercial, or Electric Utility fuel combustion
