Air Pollution from Nonroad Diesel Engines (Inventory)
Percentage of mobile source diesel PM from nonroad diesels 47%
Percentage of mobile source NOx from nonroad diesels 25%
Population Affected
Number of people living in counties violating air quality standards for PM2.5 65 million
Number of people living in nonattainment areas for 8-hr ozone 159 million
Industry Characterization
Number of pieces of nonroad diesel equipment covered by this rule sold in the United States per year over 650,000
Number of pieces of nonroad diesel equipment in categories covered by this rule currently in use about 6 million
Number of nonroad diesel engine manufacturers affected by this rule (worldwide) about 50

Days that adults have to restrict activity because of their respiratory systems 5.8 million
Annual Costs and Benefits When the Fleet of Older Nonroad Engines Has Fully Turned Over by 2030

Overall fuel cost increase

-- Equivalent fuel cost savings from reduced equipment maintenance costs (due to low sulfur diesel fuel)
-----------------------------------------------------------------------------

Net fuel cost increase

7 cents/gallon

-- 3 cents/gallon

------------------

4 cents/gallon

Equipment cost increase as fraction of total equipment price (for most mobile equipment categories) 1-3 percent
Annual cost of program $2 billion
Annual monetary value of benefits $80 billion
