Texas Houston/Galveston Area Ozone Attainment Plan Summary Purpose of Plan: To demonstrate that the Houston area will meet air quality standards by the attainment deadline of Area Covered: Houston/Galveston area, Texas (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller counties) Type of Pollutant: Ozone (caused by reactions between VOCs and NOx). Texas Houston/Galveston Area Ozone Post Rate of Progress Plan Purpose of Plan: To reduce emissions of Volatile Organic Compounds (VOCs) and Nitrogen Oxides (NOx) by 9% between and Area Covered: Houston/Galveston area, Texas (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller counties). Type of Pollutant: Ozone (caused by reactions between . As of Decem , for the first 11 months of reporting, a total of emission events occurring in the Houston-Galveston area had been posted on the TCEQ web site (TCEQ, a,b). The mass of VOCs, in emission events was relatively low when considered on an annual time-scale and over a broad geographic region (i.e., at the county level). pollution-related health risks relevant to the Greater Houston area (consisting of the 10 county, Houston – Sugar Land – Baytown metropolitan statistical area (MSA) as defined by the U.S. Census Bureau as of ) and used scientific judgment to distinguish among different levels of chronic risk likely to be experienced by Houston Size: KB.
The Houston-Galveston area (HGA) is designated as a severe ozone non-attainment region, and the State of Texas is charged with developing a State Implementation Plan (SIP) for reducing emissions. Yet despite historical gains, Houston is currently ranked by the American Lung Association as the 6th most polluted city in the nation for ozone and the 30th most polluted city for annual average particle concentrations. 40 And, notwithstanding the apparent downward trajectory in ambient levels of many HAPs, there is evidence that Houstonians are still exposed to airborne concentrations Cited by: 9. an emission event of more than kg occurs, on average, a few times a week somewhere among the hundreds of facilities and the thousands of non-EGU industrial emission points in the Houston area (Murphy and Allen, ). So, at any single facility or process unit, an emissionFile Size: KB. The first-ever analysis of county-by-county carbon dioxide emissions in the United States found that Harris County, which emits million tons of CO2 per year, narrowly edged Los Angeles for.
The EPA measures ozone in terms of parts per billion, and after changing acceptable standards from 75 ppb to 70 ppb in , a nonattainment area has ozone levels exceeding 70 : Rebecca Hennes. and propene from industrial emission sources in the Houston area by examining the trends of emissions from industrial sources between and HR VOCs were additionally identi ed using. Alerts notifying residents of unhealthy levels of ozone in the Houston-Galveston area are issued after monitoring equipment performs high-tech tests on outdoor air, but people can carry out similar type of readings for the pollutant, a cause of numerous respiratory health problems. AQI conditions and forecasts for the Houston-Galveston-Brazoria area: Call () for the bureau’s morning air pollution forecast recording. The recording is updated each weekday morning by bureau’s personnel, and is based on daily forecasts by the TCEQ.
