The Environmental Protection Agency (EPA) is proposing approval of two State Implementation Plan (SIP) revisions submitted by the State of Colorado. The revisions involve amendments to Colorado's Regulation Number 11, "Motor Vehicle Emissions Inspection Program." The revisions enhance the use of Regulation Number 11's Clean Screen Program, allow self-inspecting vehicle fleets to use the On-Board Diagnostics (OBD) testing procedure, provide corrections to the Low Emitter Index (LEI) component of the Clean Screen Program, clarify existing provisions, correct administrative errors, delete obsolete language, establish inspection procedures for when emission control equipment tampering is detected, and make several other minor associated revisions. These actions are being taken under section 110 of the Clean Air Act (CAA).
The agency’s own summary, as published.
