PROPOSED RULES

Approval and Promulgation of Implementation; Texas; Houston: Reasonable Further Progress Plan,
Contingency Measures, and Transportation Conformity Budgets for the 1997 8-Hour Severe Ozone
Nonattainment Area [FR DOC# 2013-21883] SUMMARY: The EPA is proposing to approve revisions to the
Texas State Implementation Plan to the emissions inventory (EI), the reasonable further progress (RFP) plan
and contingency measures, the vehicle miles traveled (VMT) offset analysis, and transportation conformity
motor vehicle emissions budgets associated with the reasonable further progress portion of these revisions.
The EPA is proposing to approve these revisions because they satisfy the EI, the RFP, the VMT offset, and
transportation conformity requirements for areas classified as severe nonattainment for the 1997 8-hour
ozone national ambient air quality standard and demonstrate further progress in reducing ozone precursors.

Approval and Promulgation of Implementation Plans; Texas; Attainment Demonstration for the Houston-
Galveston-Brazoria 1997 8-Hour Ozone Nonattainment Area [FR DOC# 2013-21886] SUMMARY: EPA is
proposing to approve State Implementation Plan (SIP) submittals from the State of Texas for the Houston-
Galveston-Brazoria 1997 8-hour ozone nonattainment area (HGB area). EPA is proposing approval of the
following SIP Clean Air Act required elements from Texas for the HGB area: The attainment demonstration for
the 1997 ozone National Ambient Air Quality Standards (NAAQS), the reasonably available control measures
(RACM) demonstration for the NAAQS, the contingency measures plan in the event of failure to attain the
NAAQS by the applicable attainment date, and a Motor Vehicle Emissions Budget (MVEB) for 2018, which is
the attainment year for the area. EPA is also proposing to approve revisions to the air pollution control
measures and General Air Quality Definitions in the Texas SIP. The revisions to the air pollution control
measures include revisions to the Mass Emissions Cap and Trade (MECT) program for nitrogen oxides
(NO<INF>X</INF>), revisions to the highly reactive volatile organic compound (HRVOC) emissions cap and
