Connecticut’s Methodology for Developing Locomotive Emissions 

for the 2007 MANE-VU Inventory 
H - 1 

The 2007 locomotive emissions were grown from 2005 survey data using the activity data and locomotive 

emission calculation methods from CT DEEP’s draft 2005 periodic emissions inventory (2005 PEI), as 

documented in the 2005 PEI excerpt found in Section 3.6 of Appendix F. 

Growth of the 2005 locomotive fuel use to 2007 was based on the adjusted sales of Distillate Fuel Oil and 

Residual Fuel Oil Adjusted Sales Data presented in Table 23 (see below) of the Department of Energy 

(DOE) / Energy Information Administration (EIA) reports prepared by the Energy Information 

Administration, the independent statistical and analytical agency within the Department of Energy. 

The 2005 data was obtained from DOE/EIA-0535(05) Distribution Category UC-950, Fuel Oil and 

Kerosene Sales 2005, dated November 2006, issued by the Energy Information Administration Office of 

Oil and Gas U.S. Department of Energy Washington DC 20585, available at the following website:

The 2007 data was obtained from DOE/EIA-0535(07) Distribution Category UC-950, Fuel Oil and 

Kerosene Sales 2007, dated December 2008, issued by the Energy Information Administration Office of 

Oil and Gas U.S. Department of Energy Washington DC 20585, available at the following website:

2005 coal locomotive emissions from entertainment rail are a small contributor and were reported for 

2007 as the same values as reported for 2005. 

 

Emission factors used for the 2007 particulate matter emission factors are presented in the table that 

follows. All other supporting information for the 2007 locomotive emission estimates can be found in
