Trifluralin

Chemical Information:

Alternate Names - 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl)-benzamine, benzeneamine

General Uses - Trifluralin is an herbicide used primarily on cotton and soybean crops. Production of
trifluralin has declined since restrictions on product formulation were implemented in 1982 due to
carcinogenicity and mutagenicity concerns. It is used on soybean crops, cotton, wheat, alfalfa,
sunflowers, as well as certain other crops.

For 2005, 11 facilities reported approximately 47,000 pounds of trifluralin, representing a significant decrease
of approximately 46,000 pounds, or 50 percent, compared to the total quantity of trifluralin reported by 16
facilities for 2001. In 2004 the quantity increased by approximately 24,000 pounds due to the production of a
specific fungicide at a facility in Iowa (Exhibit 4.183).

Since 2001, facilities in EPA Region 7 consistently reported most of the trifluralin, including approximately 63
percent of the total quantity reported for 2005 (Exhibit 4.186). However, facilities in Region 7 reported a
decrease of approximately 52,000 pounds or 63 percent, compared to the quantity reported for 2001. Facilities

in four other states that had reported trifluralin for 2001-2004 did not report this PC for 2005. Facilities in
Iowa, Texas, and Missouri reported approximately 84 percent of the total quantity of trifluralin for 2005.

Exhibit 4.187 shows the quantity of trifluralin for 2001-2005, by state and county. One facility, located in Polk
County, Iowa reported 42 percent of the total national quantity of trifluralin for 2005. Two other facilities in
Iowa, one each in Hamilton County and Muscatine County, had reported significant quantities for 2001, but
none for 2005. A facility in Davidson County, Tennessee reported trifluralin for the first time for 2005,
reporting approximately 3,700 pounds.

For 2005, facilities in five industry sectors reported trifluralin. Exhibit 4.188 shows the quantity of trifluralin
for each industry sector (SIC code) in which facilities reported this PC for 2001-2005. Facilities in SIC 2879
(Pesticides and agricultural chemicals, nec) reported the largest quantities of trifluralin from 2001 to 2005,
representing approximately 85 percent of the total quantity for 2005. These facilities primarily blend/formulate
pesticides and herbicides for agricultural and turf uses.

Exhibit 4.189 shows the national trends for how facilities managed trifluralin in 2001-2005.

Disposal: Compared to 2001, facilities reported a decrease of approximately 6,400 pounds or 49 percent for
2005. Since 2003, facilities disposed of approximately an average of 5,000 pounds or 9 percent of trifluralin
each year.

Energy Recovery: No energy recovery was reported.

Treatment: Since 2001, facilities treated approximately 88 percent of trifluralin.

Recycling: One facility, located in Ohio, reported virtually 100 percent of the quantity of trifluralin recycled
since 2001.

31 For additional information on recycled quantities see footnote 8.
