Metro Vancouver staff include qualified professionals who conduct dispersion model reviews to ensure consistency between projects and maintain a level playing field. Metro Vancouver also requests that other agencies provide comment on dispersion model results in specific areas such as human health.
Internal dispersion modelling review process
Metro Vancouver has a rigorous, two-stage internal review process of the dispersion modelling methodology and results.
Review and approve a detailed dispersion modelling plan of the proposed methodology and inputs using the template available on the apply for a permit page. This stage typically involves several iterations of Metro Vancouver staff providing comments on a draft plan and the applicant’s consultant responding. The methodology is expected to be mostly consistent with the BC Air Quality Dispersion Modelling Guideline.
