Hydrogen sulfide is a poisonous, flammable gas made up of two hydrogen atoms and one sulfur atom. |
EPA added hydrogen sulfide to the TRI list of toxic chemicals in 1993, but placed an administrative stay on it in order to evaluate issues brought up after issuing the final rule. Facilities did not have to file annual TRI reports for hydrogen sulfide because of the stay. Now facilities must submit reports about the use, environmental release, and chemical management activities of hydrogen sulfide. This means communities will have additional information about this toxic chemical.
Hydrogen sulfide (CAS 7783-06-4) occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs (that “rotten egg” smell). It can also result from the breakdown of organic matter, including human and animal wastes. Hydrogen sulfide can also result from some industrial activities. This includes food processing, coke ovens, kraft paper mills, tanneries, and petroleum refineries. People may be exposed to higher levels of hydrogen sulfide from living near wastewater treatment plants, gas or oil drilling, farms with manure storage, livestock confinement facilities, a landfill, or other such operations.
EPA added sixteen new chemicals to the Toxics Release Inventory (TRI) list of reportable chemicals. Reports for these new chemicals are due July 1, 2012.
The newly added chemicals are:
| Individual Listings | Polycyclic Aromatic Compounds (PACs) Category | ||
|---|---|---|---|
| Chemical Name | CAS Number | Chemical Name | CAS Number |
| 1-Amino-2,4-dibromoanthraquinone | 81-49-2 | 1,6-Dinitropyrene | 42397-64-8 |
| 2,2-bis(Bromomethyl)-1,3-propanediol | 3296-90-0 | 1,8-Dinitropyrene | 42397-65-9 |
| Furan | 110-00-9 | 6-Nitrochrysene | 7496-02-8 |
| Glycidol | 556-52-5 | 4-Nitropyrene | 57835-92-4 |
| Isoprene | 78-79-5 | ||
| Methyleugenol | 93-15-2 | ||
| o-Nitroanisole | 91-23-6 | ||
| Nitromethane | 75-52-5 | ||
| Phenolphthalein | 77-09-8 | ||
| Tetrafluoroethylene | 116-14-3 | ||
| Tetranitromethane | 509-14-8 | ||
| Vinyl Fluoride | 75-02-5 | ||
The reporting thresholds for the individually listed chemicals are 25,000 pounds if manufactured or processed, or 10,000 pounds if otherwise used.
The PACs category is a category of persistent, bioaccumulative, toxic (PBT) chemicals and has a lower reporting threshold of 100 pounds.
Some of the facility types expected to be impacted by this rule change include wood product and paper manufacturing, petroleum and coal products manufacturing, petroleum bulk stations and terminals, hazardous waste collection, and hazardous waste treatment and disposal facilities.
To determine whether these actions affect your facility, carefully examine the applicability criteria in part 372 subpart B of Title 40 of the Code of Federal Regulations.
