Five-Year Assessment of the Texas Ambient Monitoring Network

The public is invited to comment on the 2015 Five-Year Assessment of the Texas Ambient Air Monitoring Network.

Under 40 Code of Federal Regulations §58.10(d), states are required to submit to the United States Environmental Protection Agency (EPA) an assessment of the air monitoring network. This assessment is in addition to the annual monitoring network plan that details Texas’ compliance with ambient monitoring requirements. The five-year assessment is intended to determine whether the existing network of regulatory ambient air quality monitors still meets their required objective given shifting populations, emissions sources, and pollutant trends. As part of the assessment, the TCEQ also evaluated whether individual monitors within this network should be added, moved, or decommissioned to best understand and evaluate air quality given existing resources.

In responses to comments on the 2014 annual monitoring network plan, the TCEQ committed to providing the assessment of the El Paso area monitoring network in advance of the full, statewide monitoring network assessment. Although not required by rule, the El Paso area assessment will be available for public comments from April 2 through May 2, 2015 as a single document and again as part of the full statewide review by late May 2015.

Instructions for Comments

Comments will be taken until 5 p.m. May 2, 2015.
