According to the 1997 Directoiy of Chemical Producers (SRI 1997), only one eompany, Lomac, Ine. of Muskegon, Michigan, manufactures (that is, produees) 3,3 -dichlorobenzidine. By contrast, in 1986, there were approximately 10 suppliers of the chemical listed in the United States (NTP 1994). Current production volmnes of 3,3 -dichlorobenzidine for individual companies are considered confidential business information and cannot be reported. The United States International Trade Commission (USITC 1984a) reported a 1983 production volume of 3,3 -dichlorobenzidine-based dyes of over 18 million pounds in the United States. However, 3,3 -dichlorobenzidine is no longer used to manufacture dyes in the United States (CPMA 1998). Consimiption of 3,3 -dichlorobenzidine in the United States amoimted to 9.9 million pounds in 1987 (Hopmeier 1988). 

Cresols are used widely by industry. Information from the EPA s Toxic Release Inventory (TRI) on facilities that either manufactured or processed cresols in 1987 is outlined in Table 4-1. The TRI data should be used with caution since the 1987 data represent first-time reporting by these facilities. Only certain types of facilities were required to report. This is not an exhaustive list. According to the United States International Trade Commission (USITC 1987, 1988, 1989) and the 1989 Directory of Chemical Producers (SRI 1989), cresols are currently produced by five manufacturers in New York, New Jersey, Pennsylvania, Illinois, and Texas. USITC (1987, 1988, 1989) and Stanford Research Institute (SRI 1989) data for individual isomers and the mixture o-, p-, and m-isomers are included in Tables 4-2a through 4-2d. Data from the TRI do not agree with those from the USITC and SRI. For example, the Sloss Industries Coke Plant, which appears to meet SRI and USITC production criteria, was not listed with USITC (1987, 1988, 1989) or SRI (1989)-... 

According to the most recent edition of the United States International Trade Commission publication on U.S. production and sales of synthetic organic chemicals (USITC 1987), Union Carbide (Institute, WV), is the only domestic manufacturer of isophorone. A comparison of the list of isophorone manufacturers in USITC (1987) and USITC (1986) shows that Exxon Corporation (Bayway, NJ) also manufactured this chemical, but discontinued production in 1985. Because of the limited number of domestic manufacturers of isophorone and their desire to maintain confidentiality, up-to-date information regarding the production volume of isophorone in the U.S. is not available. In 1973, 35 million pounds of isophorone were produced in the United States (Papa and Sherman 1981) and in 1980, approximately 20-30 million pounds were produced (CMA 1981). The decrease may be because of replacement of isophorone with less costly solvents (CMA 1981).

Production in the United States in 1993 was reported to be 649 825 tonnes (United States International Trade Commission, 1994). Estimated production capacities of caprolactam in 1990 were reported as (thousand tonnes) United States, 640 western Europe, 860 eastern Europe, 895 Japan, 500 Latin America, 150 Asia, 290 (Fisher Crescen-tini, 1992). 

Production in the United States in 1991 was reported to be approximately 143 thousand tonnes (United States International Trade Commission, 1993). Information... 

World production of />ora-xylene in 1983 was 3900 thousand tonnes, of which the United States accounted for 48%, Europe 23% and Japan 16% the world production of o/ZAo-xylene in 1983 was 1300 thousand tormes, of which western Europe produced 30% and the United States 18% (WHO, 1997). In 1993, United States production of ortho-xylene was reported to be about 377 thousand tormes and of/rora-xylene was about 2600 thousand tonnes (United States International Trade Commission, 1994). United States production of mixed xylene and /rczra-xylene in 1994 was approximately 4100 and 2800 thousand tonnes, respectively (WHO, 1997).
