KeystoneCEV_EPA3reanalysis_TSD_final.pdf:  Technical Support Document describing EPA Region 3's reanalysis of model receptor near the Keystone Generating Station from the original modeling analysis submitted by Pennsylvania that had a modeled design value concentration above the accepted value of the NAAQS (196.4 ug/m[3]). Supporting analysis including EPA's modeling files are included as a separate part of the docket and are available upon request.

IndianaPA_Part75_EmissionAnalysis_TSD_final.pdf:  Technical Support Document describing EPA Region 3's analysis of Indiana, PA nonattainment SIP source Part 75 reported information including SO2 emissions and boiler heat inputs.  Supporting analyses using R (input/output/figures/tables and scripts) are included as a separate part of the docket and are available upon request.

IndianaPA_RRE_TSD_final.pdf:  Technical Support Document describing EPA Region 3's analysis of Indiana, PA nonattainment SIP's hourly varying modeled emission rates for Seward (supplemental modeling analysis) and Keystone (original SIP submittal).  These sources' modeled hourly varying emissions were part of Pennsylvania's Randomly Reassigned Emission rates used to support Seward and Keystone's long-term emission limits included in Pennsylvania's SIP to demonstrate compliance with the 1-hour SO2 NAAQS.  Supporting analyses using R (input/output/figures/tables and scripts) are included as a separate part of the docket and are available upon request.
