 | | Among the most significant emissions of organic HAP are the following: Styrene, acrylonitrile, and butadiene from styrene-based resin production, which includes the production of ABS, SAN, MABS, MBS, and polystyrene; acrylonitrile from nitrile resin production; and ethylene glycol, methanol, acetaldehyde, and dioxane from PET production. |
 | | For existing and new nitrile facilities, all acrylonitrile storage vessels with capacities greater than or equal to 3,500 gallons are required to be controlled. |
