Re-Evaluation of F2 and F3 Petroleum Hydrocarbon Management Limits

Millenium EMS Solutions Ltd.

Management limits for petroleum hydrocarbon fractions were developed to indicate concentrations where factors other than toxicity, such as aesthetics, free-phase formation or explosive hazards, may be of concern. These management limits have been applied as “upset limits” by Alberta Environment and Parks; the management limits for F2 and F3 have been problematic at many sites. However, the scientific basis of the management limits is limited and therefore it is not clear that there is a sound technical rationale for applying the existing management limits as upset limits.

The intent of the proposed project is to document the basis for the management limits, assess the feasibility of establishing management limits based on current science, and develop a path forward for the development of more defensible management limits.
