<br /> 4. PRODUCTION, IMPORT, USE, AND DISPOSAL
<br /> 4.1 PRODUCTION
<br /> I
<br /> No data concerning recent production volumes for 1, 2-dibromo-3-thloro-
<br /> propane were found. 10 has been reported that 1,2-dibromo-3-chloropropane is
<br /> i no longer manufactured in the United States (Hawley 1981 ; Sax and Lewis 1987) .
<br /> R.W. Grae£'f & Co. , Inc. , which is located in Old Greenwich, Connecticut, is
<br /> listed ac a currant supplier of 1, 20 0 vomo-3-chloropropane in the United
<br /> States (OPD 1989) , probably for research purposes. It is not known whether
<br /> this supplier produces 1,20ibromo-3-chloropropane in the United States or
<br /> imports the chemical, TNv companies were listed as 19YI producers of
<br /> 1,2-dibromo-3-chloropropane (EPA 1989b) . The production volume of Columbia
<br /> Organic Chemicals Co. , located Q Columbia, South Carolina, was listed as less
<br /> than 1,000 pounds, There was nu production volume listed for the other
<br /> producer, Velsicol Chemical Corp, , located in El Dorado, Arkansas. As
<br /> 1 ,2-dibromo-3-chloroptropane is no longer used as a fumigant and nematocide in
<br /> the United States, it is likely that its current production volume in the
<br /> United States , if any, is very low.
<br /> 4.2 IMPORT/EXPORT
<br /> No data concerning the recent import or export of 1,2-dibromo-3-chloro-
<br /> propane in the United States were found, R.W. Greeff & Co. , Inc. , located in
<br /> Old Cr.eenwich, Connecticut_, is listed as a current supplier of 1,2-diUromo-
<br /> 3-chloropropane (OPD 1989) and may be an importer of the chemical. It: is
<br /> unlikely that significant amounts of the chemical are imported into the United
<br /> States since its former major uses as a soil fumigant and nPmnocide are no
<br /> longer permitted in the United Scatos (EPA 1977 , 1179, 1985h, 1985c) . No
<br /> signific&nt exports are expected since it has been reported that 1 , 2-di.bromo-
<br /> 3-chloro-propane is no longex made in the United Status (Hawley ..981; Sax and
<br /> Lewis 1987) . Ameribrom Inc , , located in New York, New York, was listed as a
<br /> 1977 importer of 1, 2-dibromo-3-chloropropane; no import volume was listed (EPA
<br /> 1989b) .
<br /> 4.3 USE
<br /> 10-Dibromo-3-chloropropane is used as an intermediate in organic
<br /> synthesis (Verschueren 1983) . Until 1977, 1,2-dibromo-3-chloropropane was
<br /> extensively used as a soil fumlgant, and nematocide on over 40 different crops
<br /> in the United States (Anonymous 1988) . The chemical was used to grow field
<br /> crops, vegetables, fruits and nuts , nursery and greenhouse crops, and turf
<br /> (NTP 1985) . From 1977 to 1979, EPA suspended registration of products
<br /> containing 1,2-dibromo-3-chloropropane except .for use on pineapples in Hawaii
<br /> (Anonymous 1988; EPA 1977 , 1979) . 1n 1.985, CPA issued an intent to cancel all
<br /> registrations for 1 ,2-dibromo-3-chloropropane-containing pesticide products.
<br /> Those used on pineapples were included. Subsequently, the use of existing
<br /> stocks of 1,2-dibroma-3-chloropropane on pineapples was prohibited (EPA 1985b,
<br /> 1985c) .
