Therefore, the summationof theindividual release quantities (Total Air, Surface Water Discharges, On-Site Land, and Off-Site) will not equal the adjusted Total Release andTotal On-Site Release amounts. The adjustments in the individual release columns are for informational purposes only.To account for releases from facilities where wood preserving is conducted but where the primary NAICS code is not 321114, additionalsearches were run for CY2007 to identify all reported releases from all reporting wood preservers, using both TRI.NET and the EPA's Envirofactswebsite. To account for the releases from these facilities in years prior to 2007, the ratio between the 2007 releases from all wood preserversand the 2007 releases from those with primary NAICS code 321114 was used to adjust the reported wood preserving releases for each reportingyear in the initial trend analysis.Table 5:Ratio of All Wood Preservers' Releases to Total Releases from All Industries (NOTE 2)Initial trend analysis conducted using EPA program, TRI.NET. This analysis was run for reporters who indicated that their primary NAICS codewas 321114, Wood Preservation. This analysis also returned the total amount of releases from all industries for each reportingyear, as shown inTable 3.Table 4:Ratio of NAICS Code 321114 Releases to Total Releases from All Industries (NOTE 1)Page 2 of 2
