Dear Administrator Regan: We, the undersigned, have a shared interest in the proposed rule to establish a stronger national standard to reduce nitrogen oxides (NOx) emissions from heavy-duty commercial vehicles. We support the push for cleaner air and healthier communities for all, and stand ready to serve as constructive partners as EPA develops a workable final rule that will achieve those results.
To that end, we strongly encourage you to keep two key considerations in mind as you work toward a final rule.
