2,4,5 - Trichlorophenol (2,4,5-TCP)

Chemical Information:

Alternate Names - Collunosol, Dowicide 2

General Uses - 2,4,5-TCP is used as a fungicide to destroy or prevent fungi from growing. It is also
used as a herbicide and to make other pesticides.

From 2001 to 2005, only one facility reported 2,4,5-TCP (Exhibit 4.9). Since 2003, when this facility reported
the peak quantity of approximately 23,000 pounds, the quantity has decreased each year to 3,800 pounds in
2005. This decrease reflects a smaller volume of wastewater (containing 2,4,5-TCP) received from offsite
sources for treatment by this facility.

Where and in Which industry Was 2,4,5-Trichlorophenol Generated?

Since 2001, the one facility that reported 2,4,5-TCP was located in Salem County, New Jersey - within EPA
Region 2. From 2001-2004, this facility reported its primary SIC code to be SIC 2869 (Industrial organic
chemicals, nec); for 2005, it reported its primary SIC code to be SIC 2865 (Cyclic crudes and intermediates).

How Did This Facility Manage 2,4,5-Trichlorophenol?

Since 2001, one facility treated virtually all the 2,4,5-TCP (Exhibit 4.10). The 2,4,5-TCP is contained in
wastewaters received from offsite sources for treatment by this facility
