Website Purpose

Cheniere Energy and Gulf Coast Growth Ventures (GCGV) sponsored the establishment and maintenance of three air-monitoring stations in the Gregory-Portland area. The leadership of the Gregory-Portland Independent School District (Gregory-Portland ISD) recognized the need for a single website to host, report and provide analyses of the data from all three stations. This website serves that purpose and provides... Continue Reading a single location to report the data that is publicly accessible, easy to use and easily understood.

The University of Texas at Austin (UT Austin) was hired to design and maintain this website and to provide periodic independent analyses of the air monitoring data. UT Austin is also responsible for ensuring that only measurement data obtained using Environmental Protection Agency (EPA) federal reference or equivalent methods and instrumentation approved for air quality monitoring are reported on the website. This includes employing quality assurance protocols that ensure the data meet or exceed EPA's requirements for air quality monitoring.

Website Focus Group

To ensure the website's usefulness and ease of use by the Gregory-Portland community, UT Austin convened a focus group composed of Gregory-Portland area residents, nominated by Cheniere and GCGV, to provide input into the design of the website and its content.

The focus group reviewed and selected preferred formats to display and explain data and then specified preferences for the website's content and organization to best facilitate an understanding of the air monitoring data, analyses and other relevant information.

The UT Austin project team greatly appreciates the work of the focus group. The table in this section lists the members of the focus group.
