METHODOLOGY:

Data collection began on September 5, 2017, with help from Athena Matyear. There were only 39 final reports filed at that time. This limits our data, as final reports replace the initial reports on the TCEQ website after being filed (out of 143 final reports). Thus, 39 initial reports filed by 26 distinct facilities are missing from our collection.

For comparison sake, we included the ability to swap between data from initial and final estimates of pollution reported to TCEQ. Users can see which companies initially underestimated their air pollution, and which companies over-estimated the extent of pollution.

We included every incident reported to TCEQ Regions 10 (Beaumont), 12 (Houston) and 14 (Corpus Christi) from August 23, 2017, when many refineries began to shut down, to September 25, 2017, a month after Harvey made landfall. We also included data from other TCEQ regions when reports clearly indicated that the pollution was a consequence of hurricane Harvey.

As of October 24, 2017, not all final reports have been published. 20 final reports remain un-filed. Many of these reports are “opacity events,” an industry term for smoke pollution at facilities, which are not measured in pounds and will not affect current totals.

We merged a few groups of chemicals for the sake of simplifying some of the data that is displayed. We consolidated various types of butanes, butenes, pentanes, pentenes, and xylenes, which were (infrequently) reported by companies with specific isomers or variations. We merged “xylene, mixed isomers” and “xylene-n” into “xylenes,” as an example. We also combined nitrogen oxide (NO) and nitrogen dioxide (NO2) to display as “Nitrogen Oxides (NOx),” as both chemicals have similar effects in terms of acid rain, smog formation, and human health. All other chemicals are listed exactly as companies reported them. If in doubt, follow our sources to the TCEQ website and look at the exact entry by the company.

“Most Hazardous Chemicals”

With credit to a September 1, 2017 report by Shaye Wolf at the Center for Biological Diversity, our “most hazardous chemicals” list is very similar:

“Parent Company”

In many cases, the TCEQ reports filed by petrochemical and industrial facilities are credited to the company that owns or operates the facility, but not the ultimate parent company. To the best of our ability, we have identified the ultimate parent company of each of the subsidiaries that filed reports.

“Source Report No.”

Each TCEQ has a six-digit number attributed to it. Adding this feature as a row or column of the database allows you to click on individual cells and open up the primary source data, and a link to the TCEQ page.

“Equipment Source of Contaminant”

Many of the facilities that were hit by Harvey are very large, and emitted air pollution from several distinct areas within the facility. The TCEQ reports specify which equpiment that chemicals were leaked, spilled, or flared from.

ENVIRONMENTAL JUSTICE DATA:

Population demographics around specific industrial facilities was published in 2016 by the Political Economy Research Institute (PERI) at the University of Massachusetts, Amherst. See PERI’s methodology for “environmental justice ratios” which notes that “in 2014 in the U.S., the share of people living in poverty was 14.5% and the share of the population that identified as Hispanic or nonwhite was 36.3 percent.”

This data is displayed as “Population Living in Poverty (%)” and “Population People of Color (%).” It is only applicable to specific facilities–for example, the data will not display as averages if you attempt to apply “Population People of Color” to the county of Brazoria, or to all facilities owned by ExxonMobil.

Some data was not available, but for seven facilities without available data, we were able to locate other facilities in the PERI database that are physically close (within a mile) of the facility without data. Here are the exact substitutions we used:

And, for the Magellan Midstream facility in Galena Park, data was provided by the Union of Concerned Scientists and T.e.j.a.s. 2016 report, “Double Jeopardy in Houston.”

SOURCE DATA:

Our source spreadsheet is available for download, below.

Primary sources directly from TCEQ is easy to access, via a pop-up menu, by clicking the any of the cells in the database while the “Source Report No.” realm is included.

Greenpeace compiled air pollution reports submitted to the Texas Commission on Environmental Quality (TCEQ) that occurred during the Hurricane Harvey disaster. TCEQ reports submitted by petrochemical refineries, chemical plants, oil & gas compressor stations, terminals, and other industrial sites provide estimates of the type and amounts of chemicals released, in pounds. Data includes pollution from the shutdown and start-up process for many refineries and chemical plants, as well as releases due to physical damage from Harvey.

This data is voluntarily reported by the facilities and companies. There were no official air monitoring efforts by state or federal officials during and after hurricane Harvey, and thus, no way to verify data submitted to TCEQ.

Greenpeace’s database does not include filings to the Texas Railroad Commission, the U.S. Environmental Protection Agency (EPA), the U.S. Coast Guard, or any other government agencies.

Data does not include estimates of chemicals released from Superfund sites, Brownfields, sewage and water treatment facilities, or other potential point-sources of air and water pollution reported after the storm.
