Feasibility andl Cost-Effectiveness off 

Controlling Emissions From Diesel 

Engine in Rail, Mat-ine, Construction, 

Farm, and Other Mobile Off-Highway 

Equipment; Availability of a Draft 

Study 

AGENCV: Environmental Protection 

Agency (EPA). 

ACTIOS.: Notice of availability of a draft 

study; request for review and comment. 

SUMMARY: This notice announces the 

availability of a draft study performed 

for EPA by Radian Corporation, which 

examined the feasibility and cost 

effectiveness of reducing hydrocarbons 

(HC), carbon monoxide (CO), nitrous 

oxide (NOx), and particulate matter 

(PM) emissions from a variety of offhighway mobile diesel engine sources. 

The emission sources examined include 

rail, construction, farm, marine, and 

other mobile off-highway diesel 

equipment [e.g., diesel refrigeration 

units). 

The report concludes that off-highway 

diesel engines contribute a significant 

amount of emissions to nationwide 

emission inventories, and that 

significant reductions in HC, NOx and 

PM could be attained from these sources 

at a relatively low cost by applying 

predominantly existing control 

technologies which have been 

developed for on-highway diesel engines 

to the very similar off-highway engines. 

More specifically, the report finds that 

off-highway diesel vehicles emit 12.6 

percent of nationwide NOx emissions, 

2.4 percent'of particulate matter, one 

percent of HC and 1.25 percent of CO. 

On-highway diesels, while burning 30 

percent more fuel them off-highway 

diesels, contribute about 10 percent of 

the NOx emissions inventory, 4.2 

percent of PM, 1.1 percent of HC and 

one percent of CO emissions inventory. 

Potential emission reductions obtained 

from applying existing technologies to 

the off-highway diesel engines range 

from 38 to 88 percent depending on the 

source and pollutant type. Cost 

effectiveness estimates for HC plus NOx 

range from a few hundred to three 

thousand dollars per ton; estimates for 

PM range from one to nine thousand 

dollars per ton. 

Although comments on all aspects of 

the report are requested and 

encouraged, EPA is specifically 

soliciting comments in four general 

areas. First, comments are requested on 

the emission factors and resulting 

emissions/inventories from current 

diesel engines. Second, comments are 

requested on the applicability of 

technologies to each type of diesel 

engine in meeting the suggested 

intermediate and advanced emission 

standards, and the emission reductions 

assocaited with these technologies. 

Third, comments are requested on the 

costs used for various emission control 

technologies in the cost effectiveness 

analyses. And last, although this issue 

was not addressed in the study EPA is 

requesting specific comments and data 

on the location (urban versus rural) of 

emissions form these off-highway diesel 

sources (the report lists only nationwide 

emission reductions). This information is 

important in assessing the air quality, 

health, and welfare benefits in urban 

and rural areas of potential EPA 

regulatory actions. 

EPA does not have explicit legal 

authority to regulate emissions from offhighway sources. However, there has 

been congressional interest in granting 

EPA authority to regulate emissions 

from these sources. Therefore, EPA will 

be further assessing emissions from offhighway vehicles to determine whether 

there is a need to control such 

emissions, and comments received on 

this report will assist in this assessment. 

DATES: Written comments on the study 

are requested on or before April 17, 

1989. 

ADDRESSES: Written comments should 

be submitted (in duplicate, if possible)
