SIP Development Plan

Updated March 13, 2014

Purpose: The purpose of this document is to present a basic approach to the Grants Pass PM10 SIP development process, including major milestones and due dates. It presents the basic SIP elements the Clean Air Act requires. It also presents any potential issues that will need to be addressed in the process. More detailed elements of the technical approach will be presented in the Inventory Preparation Plan (IPP).

Title: Grants Pass Limited Maintenance Plans for PM10  

EPA Team: Lucy Edmonds (lead)

ODEQ Team: Aida Biberic (lead), Chris Swab (technical), Wes Risher (technical), Brandy Albertson (technical), Anthony Barnack (technical), David Collier (planning manager)

Background and Purpose

Grants Pass meets the federal standards for PM10 and new State Implementation Plan revision is necessary to explain how this area will continue to meet the standards through 2024. The Clean Air Act (CAA) requires two 10-year maintenance plans for PM10. The first 10-year maintenance plan for PM10 plan was submitted in 2002.

ODEQ will pursue a streamlined Limited Maintenance Plan for Grants Pass because the PM10 concentrations are below the screening thresholds and meet other criteria. LMPs are for areas that show little risk of re-violating the PM10 NAAQS.

Consultation and Coordination

DEQ and EPA will periodically consult on these plans throughout the development process
