El Paso State Implementation Plan (SIP) Revision to Incorporate a Revised Memorandum of Agreement (MOA) with the City of El Paso

On January 25, 2012, the commission adopted a SIP Revision to incorporate a revised MOA between the Texas Commission on Environmental Quality (TCEQ) and the City of El Paso into the El Paso SIP for particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10) (Project No. 2011-010-SIP-NR).

This SIP revision incorporated the changes to 30 Texas Administrative Code (TAC) §111.147 in a concurrent rulemaking ( Rule Project No. 2010-046-111-EN ) and a revised MOA between the City of El Paso and the TCEQ ( Project No. 2011-026-MIS-NR ) into the El Paso PM10 SIP. The 2001 MOA with the City of El Paso was revised to reflect the alternative control measures in the revisions to 30 TAC §111.147 and the respective responsibilities of the City of El Paso and the TCEQ under the SIP.

The EPA approved this SIP revision on December 14, 2015 ( 80 FR 77253 ).
