3. Impact of Changes to Reporting Requirements in 2014
There were no changes to NPRI reporting requirements for the 2015 reporting year. However, several changes were made for the 2014 reporting year. This section provides a brief comparative analysis of how these changes have affected facility-reported information for the 2014 and 2015 reporting years.
Additions: Two substances, thallium (and its compounds) and 2-(2-methoxyethoxy)ethanol, were added to Part 1 of the NPRI substance list for the 2014 reporting year.
2-(2-methoxyethoxy)ethanol: For the 2014 reporting year, nine facilities reported 0.0458 tonnes of releases of 2-(2-methoxyethoxy)ethanol. For 2015, ten facilities reported 0.0319 tonnes, a 30% decrease from the previous year. Most of the releases of this substance were reported by one paint and coating manufacturing facility, who reported changes in production levels for their decrease in reported releases between 2014 and 2015.
Thallium (and its compounds): For the 2014 reporting year, 20 facilities reported releases of 2,874 kg of thallium (and its compounds). In 2015, eight additional facilities reported thallium (and its compounds), with 28 facilities reporting 3,390 kg of releases (an 18% increase). Most of this increase in releases is due to a lead and zinc smelting facility that reported that it increased production in 2015. Almost all of the releases of thallium (and its compounds) reported to the NPRI comes from metal smelters, with other small sources including waste water treatment facilities and metal mines.
Alternate reporting threshold: 9 substances had their mass threshold for reporting reduced as of the 2014 reporting year. The changes from 2013 to 2014 and 2015 in total releases and in the total number of facilities reporting each substance are indicated in Table 3-1 below.
Seven of these substances (acrylonitrile, bisphenol A, isoprene, nonylsphenol and its ethoxylates, quinoline, toluene-2,4-diisocyanate, and toluenediisocyanate) were reported on by more facilities in the years following these changes. Five of these substances (acrylonitrile, bisphenol A, nonylsphenol and its ethoxylates, quinoline, and toluene-2,4-diisocyanate) showed corresponding increases in reported releases as well. Also of note is that fact that the number of facilities reporting bisphenol A and toluene-2,4-diisocyanate increased in both 2014 and in 2015.
The remaining two substances (hydrazine and toluene-2,6-diisocyanate) did not see an increase in the number of facilities reporting: one less facility reported releases of toluene-2,6-diisocynate in 2014 and 2015, compared with 2013, as a result of changes made to their operational practices, and the number of facilities reporting hydrazine (and its salts) did not change.
Even though the number of facilities reporting on isoprene increased (9 facilities in 2013 to 15 facilities in 2014 and 2015), releases of this substance stayed consistent between 2013 and 2014, and decreased significantly between 2014 and 2015. This is due to one facility that indicated it had instituted pollution prevention activities in both 2014 and 2015.
