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 types of data files. 

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 pollutants (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 Category

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 Rule, 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 Linux-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 comma-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 identify records that have been updated in the ptnonipm and nonpt 

files as part of the NODA so that review efforts can be appropriately prioritized. Note that each 

of the provided inventory and ancillary files has descriptive information in their headers that 

should prove useful to reviewers.

The data files included in the NODA are:
