British Columbia's contaminated-site regulation under the Environmental Management Act. It establishes numerical and risk-based standards and requirements for investigation, remediation and regulatory instruments, including Certificates of Compliance.
The Contaminated Sites Regulation (BC Reg. 375/96) operates under British Columbia's Environmental Management Act. Read the current consolidated regulation alongside provincial protocols and guidance to determine which investigation, remediation and certification requirements apply to a particular site.
BC's framework includes numerical and risk-based standards. Numerical standards cover soil, water, vapour and sediment through Schedules 3.1 to 3.4, with applicable standards selected according to the medium, land use and exposure considerations. Site-specific numerical standards and risk-based approaches may also apply. An unrelated schedule or the lowest number in a table is not a substitute for selecting the applicable standards.
A Certificate of Compliance is a regulatory instrument, separate from a laboratory result or an Approved Professional's assessment. Where the Approved Professional process applies, documents are prepared for the director's approval and issuance. Confirm the applicable pathway and submission requirements with provincial guidance rather than treating an assessment stamp as automatic certification.
Step 1, find out whether the CSR applies. Site disclosure statements, site identification triggers and property transactions often start the process. The province's site remediation pages explain when an investigation is required.
Step 2, investigate in stages. A preliminary site investigation reviews history and, where needed, samples suspected areas. A detailed site investigation then maps the extent of contamination in soil, groundwater and vapour. BC's technical guidance and protocols set how sampling and lab analysis are done.
Step 3, select the applicable standards. Match each medium to the right schedule and land or water use, or develop site-specific or risk-based standards where the regulation allows.
Step 4, choose and carry out the remedy. Options include on-site treatment, in-situ treatment, excavation with disposal at an approved facility, or risk management. Volume, soil type, access, haul distance and reuse goals shape the choice.
Step 5, confirm and apply for an instrument. Confirmatory sampling shows the remaining or treated material meets the selected standards, and the results support an application for a Certificate of Compliance or another instrument.
Where Nelson fits: Nelson's mobile thermal fleet treats hydrocarbon-impacted soil on site, in-situ systems treat contamination left in place, and Earthworks handles excavation and certified haulage where material has to move.
Also known as: BC CSR, Contaminated Sites Regulation, BC Reg 375/96.
The Contaminated Sites Regulation (BC Reg. 375/96) is British Columbia's regulation under the Environmental Management Act for investigating, remediating and certifying contaminated sites. It sets numerical and risk-based standards and the process for regulatory instruments such as Certificates of Compliance.
Schedule 3.2 holds the generic numerical water standards. The numerical schedules run from 3.1 to 3.4 across soil, water, vapour and sediment. Applicable values depend on water use and site conditions, so confirm them against the current consolidated regulation.
No. A Certificate of Compliance is a regulatory instrument issued through the provincial process. Laboratory results and an Approved Professional's assessment support an application, but they are not the certificate itself.
Yes, where the remediation plan and permits allow it. Nelson's mobile thermal fleet treats hydrocarbon-impacted soil on site and supports the verification sampling that the applicable CSR standards require.
Petroleum Hydrocarbons: treatment approach
The full spectrum of petroleum-derived organic compounds — crude oil, condensate, diesel, gasoline, jet fuel, and bunker fuel — reported analytically as total petroleum hydrocarbons (TPH) in gasoline-range (C6–C10), diesel-range (C10–C28), and heavy-range (C28–C40) fractions.
A regulatory designation for the most effective and advanced stage of development of activities and operating methods. Regulators use BAT to set minimum performance standards for pollution control and contaminated-site remediation, anchored in technical and economic feasibility rather than vendor preference.
The U.S. federal law passed in 1980 that establishes liability, cleanup standards, and the Superfund program for sites contaminated with hazardous substances. The foundational statute for U.S. environmental remediation and the basis for the 2024 designation of PFOA and PFOS as hazardous substances.
A 2001 international treaty in force since 2004 that requires signatory countries to eliminate or restrict the production, use, and release of designated Persistent Organic Pollutants, including PCBs, dioxins, furans, and a growing list of PFAS compounds.
