Emissions from these facilities are assumed to be unchanged from 1998 to 2010. Nearly all of these reductions occur in the on-road source category. This observation is further illustrated in the next section through several charts and tables. This has the effect of significantly altering the source contribution pattern for these pollutants. Figure E-2 summarizes the overall emission distribution changes that occur with the implementation of the 1997 AQMP control strategy.
Stationary sources account for five percent.
Implementation of the 1997 AQMP control strategy changes that apportionment by 2010. The stationary source contribution to the toxicity-weighted emissions increases to seven percent. The emission reductions expected from the 1997 AQMP and the draft Air Toxics Control Plan are summarized in Figure E-3 for the key pollutants of benzene, methylene chloride, perchloroethylene, diesel particulate, hexavalent chromium, and nickel. These pollutants were chosen for illustration because they are included in strategies in the plan. The reductions attributed to the plan include emissions reductions from PAR 1402 and PR 1190.
