<strong>2007</strong>-<strong>08</strong> – <strong>2017</strong>-<strong>18</strong> <strong>California</strong> <strong>State</strong> <strong>Rail</strong> <strong>Plan</strong>estimates, including individual inven<strong>to</strong>ries by county for the six air basinsidentified in the 1991 report, inven<strong>to</strong>ries for all other counties in the state with railactivities, and information on seasonal and daily variation in rail activity.The baseline inven<strong>to</strong>ry established and revised in these 1991 and 1992 reports wasbased on actual data by train type and air basin provided by the Class I railroads.Data were provided for specific segments of the rail system, including direction oftravel; number of trains; averages for miles, <strong>to</strong>ns, horsepower, and number oflocomotives; and time (in minutes) for brake and individual notches from onethrough eight. For its 2003 Almanac on Air Quality and Emissions, ARB updatedthe locomotive emission inven<strong>to</strong>ry using revised growth assumptions.Most recently, ARB made certain revisions <strong>to</strong> the inven<strong>to</strong>ry as part of its update <strong>to</strong>the “Off-Road <strong>2007</strong>” emissions model. ARB is currently working with UC Davisand the railroads <strong>to</strong> further refine the locomotive emission inven<strong>to</strong>ry, <strong>to</strong> becompleted in September 20<strong>08</strong>.AIR QUALITY AND EMISSION REGULATIONIn <strong>California</strong>, the EPA, ARB, and local air districts primarily regulate air quality.Air pollution control districts and air quality management districts are responsiblefor controlling air pollution for all sources other than mobile sources (althoughSouth Coast AQMD does have limited authority under state law over certain fleetsof 15 or more vehicles). CARB has responsibility for control of emissions frommobile sources. However, federal law preempts state and local control ofemissions from certain mobile sources, including new locomotives or locomotiveengines.The Federal Clean Air Act protects railroads and the interstate commerce theyrepresent from state interference and only allows states limited police powers <strong>to</strong>address nuisances, traffic disruption, or public safety. <strong>State</strong> air quality controls arerestricted <strong>to</strong> measures that do not affect the locomotive engines themselves.EPA has sole authority <strong>to</strong> adopt and enforce locomotive emission standards forboth new and remanufactured locomotives.In 1997, EPA adopted the first emission regulation for diesel locomotives, whichbecame effective from 2000 [63 FR <strong>18</strong>997-19804, 16 April 1998]. This 1997 ruleestablished Tier 0 through 2 emission standards for NOx, HC, CO, PM, and smokefrom new and remanufactured locomotives and locomotive engines.EPA classifies locomotives built before 1973 as “pre-controlled”. Locomotivesbuilt from 1973 <strong>to</strong> 2001 are in Tier O, Tier 1 describes those built in 2002 <strong>to</strong> 2004,and Tier 2 are 2005 and newer locomotives. Tiers 0 through 2 standards are metwithout the use of exhaust gas after treatment.In March <strong>2007</strong>, EPA proposed Tier 3 standards in a three-part program <strong>to</strong> cutemissions of PM by 90 percent and of NOx by 80 percent from all line-haul,passenger, and switch locomotives manufactured after 1972 except for existing240
