reported to both Canada’s NPRI and the US TRI decreased from 1995 to 1996, 1996 for the matched set of compa- for the matched data set. The NPRI reduction was 5␣ percent; that for TRI was 2␣ percent. The greater rable chemicals and industries in both reduction in NPRI occurred despite an increase in the number of facilities reporting and the number of PRTRs. forms submitted, while TRI’s facilities and forms decreased from 1995 to 1996. • In the matched data set, NPRI releases decreased 11␣ percent while TRI releases decreased 4␣ percent. In both countries, however, amounts of listed substances that facilities reported transferring off-site increased—by 10␣ percent in NPRI and 3␣ percent in TRI. • In TRI, a majority of facilities reported reductions in releases and transfers from their 1995 levels, while in NPRI a slight majority actually reported increases. Facilities reporting increases, facilities newly report- ing in 1996, and those reporting the same amounts in both years all contributed a larger portion of the NPRI total than in TRI. • The three provinces and three states with the largest releases were the same for 1995 and 1996: Ontario, Quebec and Alberta in NPRI and Texas, Louisiana and Ohio in TRI. Facilities in Ontario and Texas also reported the largest reductions in releases from 1995 to 1996. • Facilities in these provinces and states also reported the largest total releases and transfers: Ontario, Quebec and Alberta ranked in that order in NPRI in both years (for the matched 1995–1996 data set). Texas led TRI in both years, but Louisiana moved from third in 1995 to second in 1996, ahead of Ohio. • In both NPRI and TRI, releases and transfers of substances designated as known or suspected carcino- gens by the International Agency for Research on Cancer or by the US National Toxicological Program decreased by larger percentages than other chemicals: by 13␣ percent in NPRI and 3␣ percent in TRI. • Total releases and transfers of metals and their compounds increased in both PRTRs: by 9␣ percent in NPRI and 18␣ percent in TRI.
