The Detailed Summary tab provides totals of BREATHE datasets within a selected political or civic boundary to help inform decision-making and research. To use, select a date range for any time-dependent TCEQ layer to be included in the Detailed Summary (Emission Events, Permit Applications, Enforcement Actions, Complaints). Then, add the desired Boundary Type from the pull-down menu. Once the boundaries are displayed, select the specific boundary for which a Detailed Summary is desired such as a district boundary or neighborhood. A brief pop-up summary will be displayed, and the data for that boundary is added to this Detailed Summary tab. From there, the data can be downloaded for offline use as a .csv file or copied to the clipboard to be pasted into other applications.

Bringing Research, Education, and Advocacy Together for Houston’s Environment

The BREATHE tool was developed for use by Houston-area researchers, activists, policy-makers, and communities as a clearinghouse of publicly available environmental data and community resources aggregated into one easy-to-use source. Although much of the data presented in the BREATHE tool is publicly available, the relevance of the various datasets can be difficult to conceptualize without the availability of a clear spatial reference. By providing the data as map layers, the BREATHE tool creates detailed environmental profiles that are relevant to the user’s area of interest, customizable, and easy to understand.

In addition to online mapping capabilities, detailed reports of environmental and demographic data can be aggregated according to user-specified locations within the BREATHE tool. For most users, this can be accomplished by setting the parameters for the layers you would like to observe, adding a boundary layer, and then selecting a desired location. The data will be compiled and available for export as a csv file under the Detailed Summary tab. More advanced users interested in accessing the data sources presented in the BREATHE tool can utilize the Air Alliance BREATHE API tab to incorporate BREATHE data sources into their own projects and inquiries.

The BREATHE tool was created by Air Alliance Houston and January Advisors.

About the data

Data in this category is from the Texas Commission on Environmental Quality (TCEQ)
  • Emission Events - Any upset event or unscheduled maintenance, startup, or shutdown activity, that results in unauthorized emissions of air contaminants from one or more emissions points at a regulated entity such as refineries, chemical plants, or other industrial facility. Following the link will provide more detailed information about the event. Source: TCEQ Air Emission Event Report Database
  • TCEQ Complaints - Environmental complaints submitted to TCEQ. More details about the complaint process and data sources for this layer can be found here: Environmental Complaints.
  • Air Monitor Locations - Stationary monitors for various pollutants and meteorological conditions. BREATHE currently lists the highest reading for each pollutant from the previous 24 hours, but specific hourly average readings are available for most monitored pollutants from the site for each individual monitor.

  • Air Quality Permit Applications - derived from TCEQ’s New Source Review Permit (NSR) database.
Environmental Hazards
  • Concrete Batch Plants - Concrete batch plants are facilities that mix cement, sand, and aggregates into concrete for local construction. They are sources of particulate matter and other sources of pollution. This layer was created by Air Alliance Houston in 2017 from TCEQ concrete batch plant permit information. Updates pending.
  • Metal Recycling Plants - Metal recycling facilities in the City of Houston. Layer source via the Houston Health Department.
