README for Transport Rule Emission Inventories Notice of Data Availability ( NODA )

The revisions to emissions inventories NODA placed into the Proposed Transport Rule docket ( 75 FR 45210; Docket ID No. EPA

- HQ

- OAR

- 2009

- 0491) contains several ty pes of data f

iles. These include 2005, 2012, and 2014 emissions inventories along with ancillary data files used during the processing of the inventories

. The file names are intended to be descriptive of the file contents. There are separate files for criteria air po llutants (CAPs) and for selected hazardous air pollutants (HAPs) that were included in the emissions modeling inventories. The provided files are for three main emission inventory sectors: nonpoint ( filenames start with arinv_nonpt), point sources that are not electric generating units ( filenames start with ptinv_ptnonipm), and C ategory 3 (C3) commercial marine emissions ( filenames start with ptinv_eca). For more information on these emission sectors and how they were processed for the Proposed Transport Ru le, see the Emissions Technical Support Document available at http://www.epa.gov/ttn/chief/emch/transport/tr_proposal_emissions_tsd.pdf . Additional information and prior versions of data files are available from http://www.epa.gov/ttn/chief/emch/index.html#transport

. To see the contents of the files properly on Windows ® computers, we recommend using a text editor that supports L inux

- style line endings such as Wordpad. Note that some of the files may be too large for some older programs, but the latest versions of Microsoft ® Excel ® or Access ® should be able to import many of the data files as co mma - delimited files if the Windows computer has ample disk space and memory available

. A spreadsheet provided is with the NODA called TR_EI_NODA_relevant_CoSTpackets_and_inventories.xls that is designed to better describe the inventories and to help ident ify records that have been updated in the ptnonipm and nonpt files as part of the NODA so that review efforts can be appropriatel y prioritized

. Note that each of the provided inventory and ancillary files has descriptive information in their headers that s hould prove useful to reviewers. The data files included in the NODA are : Point source inventories for 2012 and 2014 for sources other than electric generating units: ptinv_ptnonipm_2012cr_hap2005v2_revised_08oct2010_v0_orl.txt ptinv_ptnonipm_2012cr_xpo rtfrac_cap2005v2_20nov2008_revised_08oct2010_v0_orl.txt ptinv_ptnonipm_2014cr_hap2005v2_revised_08oct2010_v0_orl.txt ptinv_ptnonipm_2014cr_xportfrac_cap2005v2_20nov2008_revised_08oct2010_v0_orl.txt New cement plants predicted to come on line by 2014 b the EPA SPPD Industrial Sector Integrated Solutions (ISIS) policy case : ptinv_ptnonipm_capHG_cementISIS_2016cr_16AUG2010_orl.txt Nonpoint emission i nventory files for 2012 and 2014 for CAPs and HAPs: arinv_nonpt_2012cr_cap_2005_WRAP_OilGas_08oct2010_v0_orl.txt arinv_nonpt_2012cr_cap_2008_TCEQ_Oklahoma_OilGas_08oct2010_v0_orl.txt arinv_nonpt_2012cr_hap_nopfc_nobafmpesticidesplus_noboilermacthg_08oct2010_v0_orl.txtarinv_nonpt_2012cr_pf4_cap_nopfc_08oct2010_v0_orl.txt
