Methoxychlor
Chemical Information:
Alternate Names - 2,2-bis(p-methoxyphenyl)-l,l,l-trichloroethane
General Uses - Methoxychlor is used to kill insects such as flies, mosquitoes, cockroaches, chiggers,
etc. Methoxychlor also is used on agricultural crops, livestock, grain storage, home gardens, and pets.
EPA has approved the use of methoxychlor as a pesticide and fumigant on more than 85 crops, such as
fruits, vegetables, forage crops, and shade trees. It may also be applied to large areas such as beaches,
estuaries, and marshes for control of flies and mosquito larvae and may be used for spray treatment of
barns, grain bins, mushroom houses, other agricultural premises, and garbage and sewage areas
(Source: EPA 2000/2001 TRI Public Data Release Report).

Since 2001, no more than one facility reported methoxychlor in any given year. No methoxychlor was reported
for either 2003 or 2005. Except for 766 pounds reported for 2004, no more than one pound was reported for the
other years (Exhibit 4.109).

Since 2001, only two facilities, one each in SIC 2819 (Industrial inorganic chemicals, nee) and (SIC 2879
(Pesticides and agricultural chemicals, nee), reported methoxychlor (Exhibit 4.111). The one facility that
reported methoxychlor for 2001- 2002 used it in fly spray for horses, but has not used it since 2002. For 2004,
the facility in SIC 2819 (Industrial inorganic chemicals, nee) reported the largest quantity of methoxychlor
during 2001-2005, but none in any other year; this facility used its onsite industrial furnace to treat wastes
containing methoxychlor that were generated by an offsite facility.

Exhibits 4.112 and 4.113 show how facilities managed methoxychlor in 2001-2005. The facility that reported methoxychlor in 2001-2002 primarily
disposed of methoxychlor. The facility that reported methoxychlor for 2004 treated methoxychlor onsite. These facilities did not report any
recycling of methoxychlor.
