2 APPENDX 1 Section 8 (a), (b) and (c) of B.C. Reg is repealed and the following substituted: (a) by repealing subsection (2) and substituting the following: (2) For the purposes of this Part, a source site is deemed to be a contaminated site if a contaminated soil relocation agreement is required in respect of contaminated soil, as described in section 6.1 (1 ), that is or will be relocated from the source site to a receiving site., and (b) in subsection (3) by striking out "Despite subsection (2), the" and substituting "The". 2 Sections 6.1 and 6.2 of the Contaminated Sites Regulation, B.C. Reg , as enacted by section 13 of B. C. Reg , are repealed and the following substituted: Standards for contaminated soil relocation 6.1 (1) The relocation of soil from a source site to a receiving site requires a contaminated soil relocation agreement if the soil that is or will be relocated is contaminated by having any substance with a concentration that, subject to subsections (2) and (3), exceeds the following numerical standards, prescribed for the purposes of section (3) of the Act, for either soil or vapour: (a) in respect of the land use of the receiving site, the lowest value of the soil standards set out in Part 1, 2 or 3, as applicable, of Schedule 3.1 of this regulation; (b) in respect of the land use, or other use, of the receiving site, the lowest value of the vapour standards set out in Schedule 3.3 of this regulation. (2) As an exception to subsection (1 ), if contaminated soil has any substance with a concentration that exceeds a soil standard protective of groundwater in respect of the: land use of the receiving site set out in Part 1 of Schedule 3.1 of this regulation, the numerical standards for soil protective of groundwater are not to be considered exceeded if either of the following applies: (a) the site-specific soil standard protective of groundwater, derived in accordance with a director's protocol, is not exceeded; (b) the water standard for groundwater set out in Schedule 3.2 of this regulation, based on the concentration resulting from a leachate test conducted in accordance with the director's protocol, is not exceeded. (3) As an exception to subsection (1), numerical standards are not to be considered exceeded for the purposes of that subsection if either of the following applies: (a) in respect of the numerical standards for soil, the background concentration in the soil of the receiving site, as determined in accordance with the director's protocol, is not exceeded; (b) in respect of the numerical standards for soil or vapour, a director's interim standard for soil or vapour, as applicable, is satisfied. page 2 of 137

3 () f the prescribed risk-based standards referred to in subsection () are met after the deposit of the relocated contaminated soil, the quality of the soil at the receiving site is suitable for the use intended. () n respect of a background risk estimate, or a background risk-based concentration, for a receiving site, the risk-based standards prescribed for the purposes of section (3) (a) of the Act are those set out in (a) section 18 of this regulation, or (b) section 18. l of this regulation, if the receiving site is a wide area receiving site. Procedures for contaminated soil relocation 6.2 For the purposes of section (3) of the Act, the following procedures, if required by the director, are prescribed in respect of the relocation of soil under a contaminated soil relocation agreement: (a) testing, in accordance with a director's protocol, the leachate from the soil to be relocated to determine whether the leachate from the soil contains a substance with a concentration that exceeds (i) the water quality standards applicable to the receiving site set out in Schedule 3.2 of this regulation, (ii) the site-specific numerical water standard of the receiving site, or (iii) a risk-based concentration for water at the receiving site; (b) if risk-based standards are applied at the receiving site, the following procedures: (i.) monitoring impacts of the substances in the relocated soil; (ii) inspecting and maintaining works considered necessary to manage contamination at the receiving site and to protect human health or the environment; (iii) site registry notations; (iv) preparation and registration of a covenant under section 219 of the Land Title Act. 3 Schedules 2.1, 3.1, 3.2, 3.3 and 3. of the Contaminated Sites Regulation, as enacted by section 18 of B.C. Reg , are repealed and the attached Schedules 2.1, 3.1, 3.2, 3.3 and 3. substituted. page 3 of 137

Substances must be analyzed using methods specified in the 201 British Columbia Environmental Laboratory Manual, as updated from time, a director's protocol or alternate methods acceptable to a director. Vapour standards of this schedule are specific to human health only. t is the responsibility of the responsible person for the site to ensure that use of the vapour standards of this schedule do 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. Vapour standards applied to soil vapour may be adjusted for depth dependent attenuation as specified in a director's protocol. Vapour standards apply to water at any site, irrespective of the water or site use, which gives rise to contaminated vapours. 6 Vapour standards agricultural, urban park and residential uses apply to soil at agricultural land use, urban park land use and residential land use sites, as well as freshwater or marine sediment at sensitive sediment sites, that give rise to contaminated vapours. Residential use vapour standards apply at both residential low density land use and residential high density land use sites, that give rise to contaminated vapours. Vapour standards for commercial use apply to soil vapour at commercial land use sites that give risk to contaminated vapours. Vapour standards for industrial use apply to soil vapour at industrial land use sites and to freshwater or marine sediment at typical sediment sites, that give rise to contaminated vapours. Vapour standards for parkade use apply to soil vapour adjacent to parkades, irrespective of the site use that gives rise to contaminated vapours. 10 Standard is adjusted based on the 2016 British Columbia Environmental Laboratory Technical Advisory Committee reference analytical detection limit for the substance.
