To ensure transit service is not adversely impacted, the ICT regulation includes exemptions to address circumstances that are beyond a transit agency’s control. Transit agencies may request an exemption from the zero-emission bus requirements. The Executive Officer will grant an exemption upon request if the specified criteria are met. To simplify the exemption application process, transit agencies are strongly encouraged to use the following templates for applicable exemptions. For best results, download these Templates and open them in Adobe Acrobat Reader.

• Template 1: When delay in bus delivery is caused by setback of construction of infrastructure needed for the zero-emission bus. (coming soon)
   
• Template 2: When available zero-emission buses cannot meet a transit agency’s daily mileage needs. (coming soon)
   
• Template 3: When available zero-emission buses do not have adequate gradeability performance to meet the transit agency’s daily needs for any bus in its fleet. (coming soon)
   
• Template 4: When a required zero-emission bus type for the applicable weight class based on gross vehicle weight rating (GVWR) is unavailable for purchase.
   
  •  Template 4.1: Zero-Emission Bus Unavailability Based on the Comprehensive Review Results for the Calendar Years 2026 Through 2028, for purchases of Class 4 cutaway, over-the-road motor coaches, and double-decker buses.
  •  Template 4.2: Zero-Emission Bus Unavailability for purchases of standard and articulated buses.
