Connecticut’s Methodology for Developing Locomotive Emissions

for the 2007 MANE-VU Inventory

### H - 1 The 2007 locomotive emissions were grown from 2005 surv ey 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 anal ytical 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 Washi ngton 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 Washi ngton DC 20585, available at the following website:

2005 coal locomotive emissions from entertainment ra il 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 20 07 locomotive emission estimates can be found in
