Footnotes

1.All values in μg/m3 unless otherwise stated. Substances must be analyzed using methods specified in a director's protocol or alternate methods acceptable to a director.
2.Vapour standards of this schedule are specific to human health only. It is the responsibility of the responsible person for the site to ensure that use of the vapour standards of this schedule does not constitute a significant risk or hazard to ecological health.
3.Soil, sediment or water giving rise to vapours must be remediated to the applicable vapour use standard for the substance.
4.Vapour standards applied to soil may be adjusted for depth dependent attenuation.
5.Vapour standards for agricultural, urban park and residential use apply to: soil at agricultural, urban park and residential land use sites; freshwater or marine sediment at sensitive sediment sites; and to water at any site, irrespective of the water or site use, which gives rise to contaminated vapours.
6.Vapour standards for commercial use apply to soil at commercial land use sites which gives rise to contaminated vapours.
7.Vapour standards for industrial use apply to soil at industrial land use sites and to freshwater or marine sediment at typical sediment sites, which gives rise to contaminated vapours.
8.One or more standards for the substance have been adjusted based on analytical detection limit for the substance.
9.Standard applies to sum of cis and trans isomers for the substance.
10.Standard applies to sum of meta and para isomers for the substance.
11.VPHv includes the sum of those compounds that elute on a 100% polydimethylsiloxane gas chromatographic column between the retention times for n-hexane (nC6) and n-tridecane (nC13) minus the sum of: benzene, ethylbenzene, n-decane, n-hexane, toluene and xylenes.
12.Standard applies to sum of meta, ortho and para isomers for the substance.
