According to reports filed by companies to the Texas Commission on Environmental Quality (TCEQ), 2.6 million kg (5.7 million pounds) of hazardous chemicals were released into the air by chemical plants, oil refineries, and industrial facilities from August 23 to September 25, following Hurricane "Harvey" landfall. 90% of total reported air pollution was released by 13 companies while 90% of the most hazardous chemicals were released by 10 companies.
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. Data collection, performed by Greenpeace with the help from Athena Matyear, began on September 5 and, as of October 25, is still missing 20 final reports which remain un-filed.
In total, 2.6 million kg (5.7 million pounds) of chemicals were released in the month after Harvey made landfall. Some 690 000 kg (1.52 million pounds) are considered particularly hazardous.
90% of the most hazardous chemicals, including benzene, 1,3-butadiene, ethylbenzene, hexane, hydrogen sulfide, nitrogen oxides, sulfur dioxide, toluene, and xylenes, were released by 10 companies. Most of those ten were refineries.
42 out of 45 facilities are located in communities with above-average rates of poverty (excludes 11 facilities without available data), and 43 out of 45 facilities with available data in communities that are disproportionately inhabited by people of color (excludes 11 facilities without available data), Greenpeace states.
