POTW Transfers Treatment
Quantities of TRI chemicals that are transferred to publicly-owned treatment works (POTWs) that are destroyed through the POTW’s treatment processes during the calendar year (January 1 - December 31). TRI Chemicals transferred to POTWs can be totally, partially or not destroyed at all by sewage treatment processes. Metals and Metal Compounds are not destroyed by POTW treatment processes. Other TRI chemicals are destroyed to varying degrees by treatment processes. This data element shows the quantity of a TRI chemical that has been destroyed by the POTW treatment processes. POTW refers to a municipal sewage treatment plant. The most common transfers of TRI chemicals to POTWs are conveyances of the toxic chemical in facility wastewater through underground sewage pipes. However, TRI chemicals can also be trucked to a POTW or transferred via other direct shipments. This data comes from Section 6.1 on the TRI Form R.
