# 93.117 Criteria and procedures: Compliance with PM and PM control measures.
The FHWA/FTA project must comply with any PM<sub>10</sub> and PM<sub>2.5</sub> control measures in the applicable implementation plan. This criterion is satisfied if the project-level conformity determination contains a written commitment from the project sponsor to include in the final plans, specifications, and estimates for the project those control measures (for the purpose of limiting PM<sub>10</sub> and PM<sub>2.5</sub> emissions from the construction activities and/or normal use and operation associated with the project) that are contained in the applicable implementation plan.
