Floor Alert
Truck Exemption Concerns
The South Coast Air Quality Management District urges you to remove a damaging amendment
to the transportation funding bill that would severely impact the South Coast District’s ability to
implement its recently-adopted air quality management plan for ozone and fine particulates.
South Coast AQMD opposes the trucking industry language because it would:
(1) Impede or preclude the South Coast District’s ability to adopt indirect source rules that may
affect trucks, such as at ports, warehouses, railyards and airports, and
(2) Prevent the South Coast District from adopting fleet rules that would clean up state and local
government fleets to zero and near zero emission levels as quickly as feasible.
Both of the programs outlined above are important parts of our air quality management plan
adopted on March 3, 2017 and approved by the California Air Resources Board on March 23,
2017.
The trucking industry exception is unnecessary and unfair. State law already imposes numerous
requirements to ensure that the South Coast District Board actively considers and minimizes the
socioeconomic impact of rules that it adopts, along with considering their cost-effectiveness, as
well as any potential conflict with other regulatory requirements. Health & Safety Code
§§40440.8, 40728.5, 40922, and 40727.2. Moreover, exempting trucks from additional feasible
emission reductions is unfair because it ultimately means other sources must contribute
additional emission reductions. Mobile sources make up 88% of the NOx emissions in the South
Coast Air Basin. NOx emissions must be reduced substantially to meet ozone and particulate
standards. In order for our residents to breathe clean air, all sources must contribute all feasible
reductions.
We strongly urge you to delete this ill-founded trucking exemption, and adopt a transportation
funding bill that is fair to all, and recognizes the need for transportation sources, especially in the
goods movement industry, to contribute to funding programs to mitigate the adverse air pollution
impacts of our growing transportation sources.
Sincerely,

Wayne Nastri, Executive Officer
