Welcome to Breathe Easy Waco!

Your Regional Partner in Air Quality

OUR MISSION

Using knowledge and action to improve air quality, reduce ozone formation, enhance health, and reduce the need for regulation in the Heart of Texas.

 

The Heart of Texas Council of Governments (HOTCOG) is an organization of local governments working together voluntarily to solve mutual problems and plan for the future of the six county area. Currently, HOTCOG has over 80 member governments made up of: counties, cities, school districts, community colleges, and special districts. HOTCOG was originally established in 1966 and serves a geographic area covering Bosque, Falls, Freestone, Hill, Limestone and McLennan counties.

 

Regional councils, by law, are political subdivisions of the state; with authority to plan and initiate needed cooperative projects but does not have powers to regulate or tax, which are exclusively assigned to cities and counties. As any other political subdivision, regional councils must abide by laws governing open meetings, open records and the conduct of public officials. HOTCOG is also required to obtain an annual audit to assure accountability of public funds.

 

Extended Outlook

Sunday 09/10/2017 Outlook

 Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the south and southwest sides of the Corpus Christi and Houston areas and on the west and southwest side of the Dallas-Fort Worth area; and "Moderate" in parts of the El Paso, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

 

Light patchy residual smoke from fires in the Pacific Northwest will continue across middle portions of the state generally along and east of a line from Muleshoe to Del Rio and along and west of a line from Paris to Freeport. The smoke by itself is not expected to be intense enough to raise the daily PM2.5 AQI beyond the "Good" range in most affected spots in this region, including parts of the Amarillo, Austin, Brownsville-McAllen, Corpus Christi, Laredo, Lubbock, Midland-Odessa, San Antonio, Tyler-Longview, Victoria, and Waco-Killeen areas. However, increased urban fine particulate levels (perhaps with limited contributions from the smoke in the outlined affected region) combined with sufficient local add-on could be enough for the daily PM2.5 AQI to reach the "Moderate" range in parts of the Dallas-Fort Worth and Houston areas.

 

Elsewhere in far Southeast Texas, moderate winds and/or lower incoming background levels should help to keep air quality in the "Good" range.

 

Monday 09/11/2017 Outlook

 Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" or possibly higher on the south and southwest sides of the Corpus Christi and Dallas-Fort Worth areas and "Moderate" in parts of the Brownsville-McAllen, El Paso, San Antonio, and Waco-Killeen areas, with highest concentrations in the afternoon and early evening.

 

Light patchy residual smoke from fires in the Pacific Northwest will continue across western portions of the state generally along and west of a line from Gainesville to Laredo. The smoke by itself is not expected to be intense enough to raise the daily PM2.5 AQI beyond the "Good" range in most affected spots in this region, including parts of the Amarillo, Austin, El Paso, Laredo, Lubbock, Midland-Odessa, San Antonio, and Waco-Killeen areas. However, increased urban fine particulate levels (perhaps with limited contributions from the smoke in the outlined affected region) combined with sufficient local add-on could be enough for the daily PM2.5 AQI to reach the "Moderate" range in parts of the Dallas-Fort Worth and Houston areas.

 

Elsewhere in the state, moderate winds and/or lower incoming background levels should help to keep air quality in the "Good" range.

 

Tuesday 09/12/2017 Extended Outlook

 Winds may be light enough and incoming background levels high enough for ozone to reach "Unhealthy for Sensitive Groups" in parts of the Houston and San Antonio areas; "Moderate" or possibly higher in parts of the Brownsville-McAllen, Corpus Christi, El Paso, Victoria, and Waco-Killeen areas; and "Moderate" in parts of the Austin, Beaumont-Port Arthur, Dallas-Fort Worth, Laredo, and Tyler-Longview areas, with highest concentrations in the afternoon and early evening.

 

Light patchy residual smoke from fires in the Pacific Northwest will continue to linger across parts of Texas generally along and north of a line from Denver City to Orange. However, the smoke itself is not expected to be intense enough to raise the daily PM2.5 AQI beyond the "Good" range in most affected spots in this region, which includes parts of the Amarillo, Beaumont-Port Arthur, Dallas-Fort Worth, Lubbock, Tyler-Longview, and Waco-Killeen areas. However, increased urban fine particulate levels (perhaps with limited contributions from the smoke) combined with sufficient local add-on could be enough for the daily PM2.5 AQI to reach the "Moderate" range in parts of the Houston and Laredo areas as well.

 

Elsewhere in the Permian Basin, moderate winds and lower incoming background levels should help to keep air quality in the "Good" range.

What is Ozone?

 

Ozone is a pollutant formed when two classes of chemicals, Nitrogen Oxides (NOx) and Volatile Organic Compounds (VOC), are exposed to sunlight.   This reaction creates several compounds of which the most hazardous to human health is ozone.  Ozone is the primary component of smog and is regulated by the US Environmental Protection Agency.

 

 

What are the Sources of NOx and VOC’s?

 

NOx is produced almost entirely as a by-product of high-temperature combustion.

 

Common sources of NOx include:

 

    • automobiles, trucks, and marine vessels

    • gasoline powered lawn equipment

    • construction equipment

    • power generation

    • industrial processes

    • natural gas furnaces

 

VOCs include many organic chemicals that vaporize easily, such as those found in gasoline and solvents. They are emitted from many sources, including:

 

    • gasoline stations

    • motor vehicles, airplanes, trains, boats

    • petroleum storage tanks

    • oil refineries

    • biogenic, or natural emissions from trees and plants
