Description: Total annual transfer quantities of the chemical in wastes to off-site locations including Publicly Owned Treatment Works (POTW).

An off-site transfer is the transfer of the toxic chemical in waste to a facility that is geographically or physically separate from the facility reporting under TRI. Chemicals reported to TRI as transferred are sent to off-site facilities for the purposes of recycling, energy recovery, treatment, or disposal. The quantities reported represent a movement of the chemical away from the reporting facility to something other than a POTW. Except for off-site transfers to disposal, these quantities do not necessarily represent entry of the chemical into the environment. Transfers to disposal represent an off-site release.

Discharges to POTWs are those toxic chemicals which are sent to a municipal sewage treatment plant. The most common transfers will be conveyances of the toxic chemical in facility wastewater through underground sewage pipes, however, materials may be trucked or other direct shipments to a POTW may be made. (Data in TRI_TRANSFER_QTY were submitted on EPA Form R, Part II, Section 6, 'Transfers of the Toxic Chemical in Wastes to Off-Site Locations'. See specific 'Data Source' for each column.)
