State Implementation Plan (SIP) Checklist Guide

Determine What Type of State Implementation Plan (SIP) is Required

  • See development of specific elements for each of the major SIP types

Timeline for the SIP Development Process

  • See Ozone NAAQS Timelines
  • Note what CAA deadlines apply to each step of SIP development and submission process.

Public Input and Other CAA SIP Development Requirements

  • Streamlining the SIP Process includes guidelines on planning and issuing public notices for each step of development, allowing for public comment.

Monitor, Model, and Inventory Emissions

  • Startup, Shutdown, and Malfunction (SSM) emissions
  • National Emissions Inventory
  • Support Center for Regulatory Atmospheric Modeling (SCRAM)

Strategies for Controlling Ozone-causing Emissions

  • RACT Information
  • Control Technique Guidelines (CTGs) and Alternate Control Techniques (ACTs)
  • Menu of Control Measures
  • RACT/BACT/LAER Clearinghouse: database of permitted emissions control processes
  • Control Strategy Tool (CoST): part of EPA's Emissions Modeling Framework (EMF). CoST models the emission reductions and engineering costs associated with control strategies for point, area, and mobile sources of air pollutant emissions

 Submit SIP to EPA for Approval

  • Streamlining the SIP Process: check SIP for efficiency and effectiveness.
  • Submit SIPs Online
  • Once the SIP meets completeness criteria, and is submitted to EPA, the state issues a state notification and allows for comment. Then after a final notice, implementation begins (adoption of SIP elements). Note: this begins before the SIP has been finally approved.

  • Regional Contacts: regional EPA representatives who can help
  • Air Quality Implementation Plans: learn how SIPs get approved by EPA.
  • The Ozone Advance Program offers additional assistance to states very near nonattainment.
  • Rules that also help states reduce emissions and meet the ozone standard
