SUB-SLAB DEPRESSURIZATION SYSTEM RETROFITS TO EXISTING BUILDINGS: TWO CASE STUDIES

摘要

Ontario Regulation 153/04 outlines the process wherein a property impacted by soil and/ or ground water contaminants is evaluated for risks to human and ecological health, and may be redeveloped for more sensitive land uses. Under the Regulation, once a property has been sufficiently characterized, a Record of Site Condition (RSC) may be filed, to document the condition of the property. Owners of contaminated lands may choose to remediate the property, to meet the Ontario Ministry of Environment and Climate Change (MOECC) generic soil and ground water Standards, or develop new site-specific Standards via the Risk Assessment (RA) process.
