Approval and Promulgation of Implementation Plans; Texas; Revisions to the Minor New Source Review (NSR) State Implementation Plan (SIP) for Portable Facilities

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Texas State Implementation Plan (SIP) submitted by the Texas Commission on Environmental Quality (TCEQ) on March 19, 2010 and July 2, 2010. These revisions to the Texas SIP revise the minor New Source Review (NSR) program to provide for the relocation and change of location of permitted portable facilities, establish definitions related to portable facilities, and establish public participation for changes of location to portable facilities. The EPA proposes to find that these revisions to the Texas SIP comply with the Federal Clean Air Act (the Act or CAA) and are consistent with our regulations and policy for minor NSR. The EPA is proposing these actions under section 110 of the Act.
