State Implementation Plan Revision: Removal of Vehicle Inspection and Maintenance Program

State implementation plans (SIP)

December 17, 2018 - January 28, 2019

Ecology is proposing to submit a revision to Washington’s State Implementation Plan (SIP) to EPA. Under state law, the vehicle inspection and maintenance (also called the vehicle I/M or emission check) program ends on December 31, 2019.  This revision would update Washington’s SIP to remove the emission check program as a control measure.

Draft SIP Revision:  Removal of Vehicle Inspection and Maintenance Program

Bajo la ley del estado, el programa de chequeo de emisiones de vehículos terminara el 31 de diciembre de 2019.  Este plan actualiza el Plan de Implementación del estado de Washington para remocionar el programa de chequeo de emisiones. El plan muestra que la remoción del programa no resultara en calidad de aire ​malsano. Para más información sobre el plan, comuníquese con Joanna Ekrem, Programa de Calidad de Aire, al 360-407-6826.

The public hearings have been CANCELLED since no one requested a public hearing by January 15, 2019.
