2014 National Air Toxics Assessment August 27, 2018 by Wilma Subra [email protected] Graphics by Michael Orr [email protected] On August 22, 2018, the Environmental Protection Agency (EPA) released the 2014 National Air Toxics Assessment (NATA). The previous 2011 National Air Toxics Assessment, released December 17, 2015, focused on air emissions of Chloroprene. Chloroprene has been released into the air in St. John the Baptist Parish of Louisiana for 49 years from the DuPont/ Denka facility in LaPlace/Reserve. NATA estimated higher than expected levels of Chloroprene in the community of LaPlace/Reserve based on the 2011 NATA report and identified the DuPont /Denka facility as creating the greatest offsite risk of cancer of any manufacturing facility in the United States. The 2014 National Air Toxics Assessment focuses on Ethylene Oxide. Louisiana has 13 facilities that release air emissions of Ethylene Oxide. Three of the five facilities in the Unite State, releasing the largest quantities of Ethylene Oxide into the air, are located in Louisiana. The number two ranking air emissions facility of Ethylene Oxide in the US (Union Carbide in Hahnville) is located in St. Charles Parish, Louisiana, just down river from DuPont /Denka. The Ethylene Oxide air emissions from the Union Carbide facility along with the Ethylene Oxide air emissions from the Evonik Materials facility in Reserve, St. John the Baptist Parish, are responsible for St. John the Baptist and St. Charles parishes having the highest risk of cancer from Ethylene Oxide in all of Louisiana and all of the United States. St. John the Baptist Parish also has the highest risk of cancer in the United States from air emissions of Chloroprene. National Air Toxics Assessment (NATA) According to the EPA, “NATA is the US EPA’s ongoing thorough evaluation of air toxics across the Unites States. EPA developed NATA as a state-of-the-science tool to inform both national and localized efforts to collect air toxics information, characterize emissions and help prioritize pollutants and areas of interest for further study to gain a better understanding of risk. The goal of NATA is to identify those air toxics which are of greatest potential concern in terms !1 of 20!

Ambient and exposure concentrations and estimates of risk and hazard of air toxics in each state are typically generated at the census tract level.” The NATA process consist of four steps: -compile a national emissions inventory of outdoor air toxics sources -estimate ambient concentrations of air toxics across the United States -estimate population exposure across the United States -determine potential public health risks from breathing air toxics NATA estimates the cancer risks from breathing air toxics over many years. The 2014 NATA process evaluated 179 Hazardous Air Pollutants that are released into the air. Ethylene Oxide EPA addressed Ethylene Oxide in the 2014 NATA because it was identified as a potential long term concern in several areas across the United States. “EPA does not expect Ethylene Oxide levels in the air in these areas to be high enough to cause immediate harm to health. The 2014 NATA estimates that Ethylene Oxide significantly contributes to potential elevated cancer risks in some census tracts across the US.” Ethylene Oxide is a Hazardous Air Pollutant (HAP) that is a flammable, colorless gas used to make other chemicals that are used in making a range of products, including antifreeze, textiles, plastics, detergents and adhesives. Ethylene Oxide is manufactured from Ethylene and is used primarily as a chemical intermediate in the manufacturing of Ethylene Glycol. Ethylene Oxide is also used to sterilize spices, equipment and plastic devices, such as medical equipment, that cannot be sterilized by steam. Health Impacts of Ethylene Oxide Ethylene Oxide is carcinogenic to humans if inhaled, based on weight of evidence. It may be a teratogen in humans since it is a teratogen in animals. Limited evidence indicates it causes spontaneous abortions. May damage developing fetus. May damage testes. Long term exposure harms the brain and nervous system. !2 of 20! Breathing air containing elevated Ethylene Oxide levels over many years increases the risk of some types of cancers, including cancers of the white blood cells (non-Hodgkin’s lymphoma, myeloma and lymphocytic leukemia) and breast cancer in females. Strong evidence that female workers have increased rate of breast cancer. Induces tumors of the brain, lungs, connective tissues, uterus and mammary glands. Facilities that Release Ethylene Oxide Synthetic Organic Chemical Manufacturing Industry Polyether Polyols Production Miscellaneous Organic Chemical Manufacturing Commercial Sterilizers Hospital Ethylene Oxide Sterilizers Based on the 2016 EPA Toxic Release Inventory, there are 118 industrial facilities in the United States releasing Ethylene Oxide into the air. In the state of Louisiana, there are 13 industrial facilities and in Texas, 25 industrial facilities releasing Ethylene Oxide into the air. Three of the top five industrial facilities in the US releasing the largest quantities of Ethylene Oxide into the air are located in Louisiana, the other two are located in Texas. Together Louisiana and Texas have the top seven industrial facilities releasing the largest quantities of Ethylene Oxide into the air in the US. Louisiana Industrial Facilities Releasing Ethylene Oxide into the Air The 13 industrial facilities releasing Ethylene Oxide into the air in Louisiana are presented on the attached table. Eleven of the industrial facilities are located along the Mississippi River Industrial Corridor, six in Iberville Parish, three in Ascension Parish and one each in St. John the Baptist and St. Charles parishes. The remaining two industrial facilities are located in Calcasieu Parish in southwest Louisiana near the Texas border. The following table lists the 13 facilities in Louisiana that report Ethylene Oxide air emissions. !3 of 20! 2016 Toxic Release Inventory of Ethylene Oxide Air Emissions in Louisiana Fugitive Stack US Facility Address Parish (lbs) (lbs) Ranking ST CHARLES 355 LA HWY 3142 (GATE 1), OPERATIONS (TAFT/ HAHNVILLE LOUISIANA ST CHARLES 5,132 30,726 2 STAR) UNION 70057 CARBIDE CORP 8404 HWY 75, GEISMAR BASF CORP.
