This Standard establishes the principles and practices that are applicable to a Phase II ESA. It is intended to provide a consistent framework and minimum requirements for conducting Phase II ESAs that can accommodate broader regulatory and liability requirements, as well as address pertinent site-specific requirements. This framework involves developing a sampling plan, preparing for and undertaking an investigation for sampling and measuring, and interpreting and reporting on the information gathered. This Standard is intended as a follow-up to CSA Standard Z768.
This Standard does not provide detailed, prescriptive methodologies for conducting Phase II ESAs under specific conditions (eg, sampling protocols).
This Standard addresses neither the methodology for Phase I ESAs nor the selection or implementation of any remediation activities, as both of these activities are beyond the scope of a Phase II ESA. Brief discussions of Phase I ESAs and the activities that can follow a Phase II ESA are presented in Appendix A.
This Standard does not attempt to provide direction for the decision-making process that follows a Phase II ESA. These business decisions are based on case-specific details that cannot be generalized for the purposes of this Standard. Decisions of this nature are best addressed on a case-by-case basis, in consultation with the appropriate environmental, legal, and business counsel.
