Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

This rule provides owners or operators of a rail yard a mechanism for quantifying, certifying, and banking 

emission reductions from installation and use of a control device which reduces emissions from locomotive 

engines in rail yards. This amendment added provisions that improved enforceability for issued credits.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

(CO) PM TAC (name):

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emissions. Attach reference(s) for emission factor(s) 

and other information. Attach calculation sheet showing how the emission information provided below was determined.

Net Effect on Emissions: Increase Decrease N/A

Emission Reduction Commitment in SIP for this Source Category: None

Inventory Year Used to Calculate Changes in Emissions: N/A Area Affected: 

Future Year Control Profile Estimate (Provide information on as many years as possible):

If ERCs are generated from this rule, emissions would decrease by at least 5% of the ERC value due to this amount going 

into the Priority Reserve Bank. Additionally, NOx emissions would be decreased by an additional 10% of the NOx ERC 

value due to a provision of the rule to take 10% for public health benefit.
