CCME Soil Quality Guidelines BC CSR CERCLA / Superfund EPA RSLs Ontario O.Reg 153/04 Dutch Intervention Values UK Part 2A Australia NEPM HILs
Regulation
Canadian Soil Quality Guidelines for the Protection of Environmental and Human Health (CCME SQG). Canada-Wide Standards for Petroleum Hydrocarbons in Soil (CWS PHC).
Governing Body
Canadian Council of Ministers of the Environment (CCME) - a federal-provincial-territorial body. Guidelines are non-binding recommendations that provinces adopt or adapt.
Trigger
CCME guidelines serve as federal benchmarks. They are triggered when provinces lack their own standards, for federal lands (airports, military bases, Indigenous reserves) or when used as reference values in site assessments and risk assessments.
Key Standards
Soil quality guidelines organized by land use: Agricultural, Residential/Parkland, Commercial and Industrial. Covers metals, PAHs, VOCs and PHC fractions (F1-F4).
Compare thresholds across jurisdictions
Penalties
CCME guidelines are not directly enforceable. Enforcement occurs at the provincial level when provinces adopt these values into their regulations. Federal lands are enforced under CEPA or Treasury Board policies.
Reporting
No federal reporting deadlines for CCME guidelines. Provincial adoption determines specific reporting requirements. Federal contaminated sites are tracked in the Federal Contaminated Sites Inventory (FCSI) with annual reporting.
Regulation
Contaminated Sites Regulation (B.C. Reg. 375/96) under the Environmental Management Act (SBC 2003, c.53). Three tiers of standards:
  • Schedule 3 - Generic Numerical Standards (most conservative, land-use based)
  • Schedule 4 - Matrix Standards (substance-specific, considers soil texture and depth)
  • Schedule 5 - Site-Specific Numerical Standards (risk-based, most commonly used in practice)
Schedule 10 addresses vapour standards. Risk-based approaches under Protocol 1 and Protocol 13.
Governing Body
BC Ministry of Environment and Climate Change Strategy. Day-to-day oversight by the Land Remediation Section. Approved Professionals (APs) conduct site investigations and issue Certificates of Compliance.
Trigger
  • Property sale or redevelopment (due diligence / lender requirements)
  • Discovery of contamination during construction or monitoring
  • Zoning or land use change
  • Independent remediation following a spill
  • Site profile submission under Part 4 of the EMA
  • Municipal rezoning or subdivision triggers mandatory site investigation for commercial/industrial lands
Key Standards
Schedule 5 is most commonly used in practice, providing substance-specific values by land use (Residential, Parkland, Commercial, Industrial, Wildland, Agricultural). Includes separate standards for soil intake, protection of drinking water and protection of aquatic life.
Look up BC CSR threshold values
Penalties
Under the EMA: fines up to $1,000,000 per day for individuals and $6,000,000 per day for corporations. Administrative penalties up to $75,000. Responsible persons include current and previous owners/operators.
Reporting
Site profiles must be submitted within 30 days of triggering events. Spill reporting to the Provincial Emergency Program (PEP) is immediate (within 24 hours). No fixed remediation deadline, but contamination must be addressed before Certificates of Compliance are issued.
Regulation
Ontario Regulation 153/04 - Record of Site Condition (as amended by O.Reg 511/09 and subsequent amendments). Two sets of standards:
  • Table 2 - Generic Full Depth Background Site Condition Standards (based on background concentrations)
  • Table 3 - Full Depth Generic Site Condition Standards (stratified by property use and groundwater condition: potable vs. non-potable)
Risk assessments under O.Reg 153/04 Part IX can derive site-specific standards.
Governing Body
Ontario Ministry of the Environment, Conservation and Parks (MECP). Records of Site Condition are filed with the Environmental Site Registry (ESR). Qualified Persons (QPs) conduct Phase 1/2 ESAs and submit RSCs.
Trigger
  • Change of land use to a more sensitive use (e.g. industrial to residential)
  • Filing a Record of Site Condition (RSC) is mandatory for property use changes defined in O.Reg 153/04
  • Brownfield redevelopment incentive programs require RSC filing
  • Voluntary cleanup seeking regulatory closure
Key Standards
Table 3 standards are property-use specific (Residential/Parkland/Institutional vs. Commercial/Industrial) and further divided by potable and non-potable groundwater conditions.
Look up Ontario threshold values
Penalties
Under the EPA: fines up to $6,000,000 per day for corporations and $100,000 per day for individuals on first offence. Subsequent offences double. Directors and officers can face personal liability, including imprisonment up to 5 years for major violations.
Reporting
RSC must be filed before land use change is permitted. Spill reporting under O.Reg 675/98 requires immediate notification to the Spills Action Centre (SAC) and written report within 30 days. RSC acknowledgment typically takes 6-8 weeks from MECP.
Regulation
Alberta Tier 1 and Tier 2 Soil and Groundwater Remediation Guidelines under the Environmental Protection and Enhancement Act (RSA 2000, c.E-12):
  • Tier 1 - Generic guidelines for standard land uses. Conservative, lookup-table approach. Most commonly applied for straightforward sites.
  • Tier 2 - Site-specific risk-based guidelines. Allows modification of Tier 1 values based on site conditions (soil type, depth to groundwater, proximity to receptors).
Managed under the Alberta Remediation Framework with exposure-pathway-based cleanup objectives.
Governing Body
Alberta Environment and Protected Areas (AEPA). Alberta Energy Regulator (AER) for upstream oil and gas sites. Remediation certificates are issued upon meeting Tier 1 or Tier 2 objectives.
Trigger
  • Release of a substance into the environment (mandatory reporting under EPEA s.110)
  • Well site or pipeline decommissioning and abandonment
  • Environmental site assessment during property transactions
  • Regulatory orders from AER or AEPA
  • Contamination discovered during development or construction
Key Standards
Tier 1 guidelines are organized by soil type (fine- and coarse-grained) and land use (Natural Area, Agricultural, Residential/Parkland, Commercial, Industrial).
Look up Alberta Tier 1 values
Penalties
Under EPEA: fines up to $500,000 per day for individuals and $1,000,000 per day for corporations on first offence. AER can issue compliance orders, suspend operations and revoke licences for oil and gas sites. Environmental protection orders (EPOs) can require immediate remediation.
Reporting
Spill reporting is immediate (24-hour notification to Alberta Environment). Remediation timelines are site-specific but AER tracks inactive well site remediation through the Liability Management Framework. Annual reporting required for active remediation sites.
Regulation
Protection and Rehabilitation of Contaminated Lands Policy (RPCS) under the Environment Quality Act. Land Rehabilitation and Protection Regulation (RLRP, c.Q-2, r.37). Uses a three-tier criteria system:
  • Criteria A - Background levels (natural concentrations)
  • Criteria B - Maximum limits for residential/institutional/recreational use
  • Criteria C - Maximum limits for commercial/industrial use
Governing Body
Ministere de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP). Municipalities may require environmental characterization studies at rezoning or development approval.
Trigger
  • Cessation of industrial or commercial activity (s.31.51 EQA)
  • Land use change to a more sensitive use
  • Contamination discovery or accidental release
  • Municipal development approvals or rezoning
Key Standards
Criteria B and C values published in Schedule I and II of the RLRP. Site-specific risk assessment available under the MELCCFP guidance when Criteria B/C cannot be met.
Penalties
Under EQA: administrative monetary penalties from $2,500 to $6,000,000 per offence. Criminal penalties up to $6,000,000 per day for corporations. Personal liability for directors and officers.
Reporting
Upon cessation of certain industrial activities, a characterization study must be submitted within 6 months. Contamination above Criteria B (residential) or C (commercial) must be reported to MELCCFP. Rehabilitation plan required within prescribed timeframes.
Regulation
CEPA 1999 (S.C. 1999, c.33): Manages toxic substances listed on Schedule 1. Applies to all federal lands and supports provincial enforcement for listed substances. Establishes the National Pollutant Release Inventory (NPRI).

Fisheries Act s.36(3): Prohibits the deposit of deleterious substances into waters frequented by fish. Extremely broad application - applies to any release that could reach fish habitat, including contaminated groundwater plumes, stormwater runoff from contaminated sites and sediment disturbance during remediation.
Governing Body
CEPA: Environment and Climate Change Canada (ECCC).
Fisheries Act: ECCC (pollution prevention) and Fisheries and Oceans Canada (DFO) for habitat protection.
Trigger
CEPA: release of a Schedule 1 toxic substance exceeding reporting thresholds. Fisheries Act: any deposit of a deleterious substance into water frequented by fish, or work near fish habitat during contaminated site remediation.
Penalties
CEPA: fines up to $6,000,000 per day (corporations); imprisonment up to 5 years for serious offences.
Fisheries Act: fines up to $6,000,000 per offence for corporations on first conviction; up to $12,000,000 for subsequent. Individual fines up to $1,000,000 or imprisonment.
Reporting
NPRI reporting is annual (June 1 deadline) for facilities meeting thresholds. Emergency spill reporting to ECCC is immediate. Fisheries Act offences are enforced reactively - no routine reporting requirement, but due diligence defence requires proactive monitoring documentation.
Regulation
CERCLA (1980, amended by SARA 1986 and the Brownfields Act 2002) establishes the Superfund program for cleanup of uncontrolled hazardous waste sites. Key processes:
  • National Priorities List (NPL) - sites with highest priority for long-term remedial action, ranked by Hazard Ranking System (HRS) score
  • Potentially Responsible Parties (PRPs) - strict, joint and several liability for current owners, past owners, generators and transporters of hazardous substances
  • EPA Regional Screening Levels (RSLs) - risk-based screening concentrations for soil, air and water. Updated semi-annually.
Compare EPA RSL values with other jurisdictions
Governing Body
U.S. Environmental Protection Agency (EPA) at the federal level. EPA delegates authority to regional offices (Regions 1-10). State environmental agencies conduct enforcement for state-led Superfund sites.
Trigger
  • Release or threatened release of hazardous substances
  • Discovery of contamination above EPA RSL screening levels
  • Citizen petitions or state referrals to EPA
  • Property transactions (due diligence under AAI rule / ASTM E1527-21 Phase I ESA standard)
Penalties
Treble damages for PRPs who refuse to cooperate with EPA orders. Civil penalties up to $70,117 per day of violation (adjusted annually for inflation). EPA can recover all cleanup costs from PRPs. Criminal penalties for knowing violations: fines and imprisonment up to 15 years.
Reporting
Release of a reportable quantity of a hazardous substance requires immediate notification to the National Response Center (NRC) within 24 hours. Written follow-up required. NPL sites have Records of Decision (RODs) with site-specific cleanup timelines. Five-year reviews required for sites with residual contamination.
Regulation
RCRA (1976, amended 1984 by HSWA) regulates the generation, transportation, treatment, storage and disposal of hazardous wastes. Subtitle C covers hazardous waste; Subtitle D covers solid (non-hazardous) waste. RCRA Corrective Action program addresses cleanup at operating or formerly operating RCRA-permitted facilities.
Governing Body
U.S. EPA. Many states have RCRA authorization to run their own programs. Hazardous waste is tracked cradle-to-grave via the manifest system.
Trigger
Generation, treatment, storage or disposal of hazardous waste (listed or characteristic). Corrective Action is triggered when a RCRA facility permit application reveals contamination, or when releases are detected from Solid Waste Management Units (SWMUs).
Penalties
Civil penalties up to $70,117 per day per violation. Criminal penalties for knowing violations: fines up to $50,000 per day and imprisonment up to 5 years. Knowing endangerment: fines up to $1,000,000 and imprisonment up to 15 years.
Reporting
Biennial hazardous waste report (EPA Form 8700-13 A/B) by March 1 of even-numbered years. Hazardous waste manifests tracked per shipment. Corrective Action milestones set by EPA consent orders or permits.
Regulation
The Clean Water Act (1972) regulates the discharge of pollutants into waters of the United States through the National Pollutant Discharge Elimination System (NPDES). Relevant to contaminated sites when remediation involves dewatering, treated groundwater discharge or stormwater runoff from disturbed areas.
Governing Body
U.S. EPA. Most states have delegated NPDES authority. States set water quality standards and issue permits.
Trigger
Any point source discharge to surface waters. During contaminated site cleanup, NPDES permits are needed for pump-and-treat effluent discharge, construction dewatering and stormwater from sites disturbing 1+ acre.
Penalties
Civil penalties up to $64,618 per day per violation (2024 adjustment). Criminal penalties for negligent violations: $2,500-$25,000 per day and/or imprisonment up to 1 year. Knowing violations: $5,000-$50,000 per day and/or up to 3 years imprisonment.
Reporting
Discharge Monitoring Reports (DMRs) per NPDES permit schedule (typically monthly or quarterly). Stormwater Pollution Prevention Plan (SWPPP) must be maintained on-site during construction. Non-compliance must be reported within 24 hours.
Overview
Most U.S. states operate Voluntary Cleanup Programs (VCPs) or brownfield programs that provide a regulatory framework for cleaning up contaminated sites outside of the federal Superfund process. Key programs:
  • California DTSC - Department of Toxic Substances Control manages the Voluntary Cleanup Program and Brownfields/Environmental Response. Uses Human Health Screening Levels (CHHSLs) and site-specific risk assessment.
  • Texas TRRP - Texas Risk Reduction Program (30 TAC Chapter 350) under TCEQ. Three response action levels: background, residential and commercial/industrial Protective Concentration Levels (PCLs).
  • New York DEC Brownfield Cleanup Program (BCP) - Provides tax credits and liability releases upon completion. Uses NYS DEC Soil Cleanup Objectives (SCOs) at unrestricted, residential, restricted-residential, commercial and industrial levels.
  • Pennsylvania Act 2 - Land Recycling and Environmental Remediation Standards Act. Three cleanup standards: background, statewide health standards (MSCs) and site-specific.
  • Florida DEP - Drycleaning Solvent and Brownfield Cleanup Programs. Soil Cleanup Target Levels (SCTLs) for direct exposure.
Trigger
Voluntary participation in most states. Triggered by property acquisition, redevelopment plans, lender requirements or desire for regulatory closure and liability protection. Some states require participation for certain property transfers.
Penalties
VCPs are voluntary, so penalties apply only for non-compliance with agreed-upon work plans or consent orders. Exiting a VCP without completing cleanup may result in referral to the state's mandatory enforcement program. Penalty ranges vary by state, typically $10,000-$50,000 per day.
Regulation
Directive 2004/35/EC establishes a framework for environmental liability based on the "polluter pays" principle. Covers damage to water, land and protected species/habitats. Applies strict liability to operators of activities listed in Annex III (waste management, dangerous substances, etc.) and fault-based liability for other activities.
Governing Body
European Commission at the EU level. Transposed into national law by each member state. Competent authorities vary by country (environment agencies or ministries).
Trigger
Land damage that creates a significant risk to human health. Imminent threat of damage or actual environmental damage caused by occupational activities. Member states define "significant risk" thresholds in national transposition.
Penalties
Penalties are set at the member state level. The directive requires operators to bear the cost of preventive and remedial actions. Many member states impose additional administrative fines and criminal sanctions for non-compliance.
Reporting
Operators must immediately notify the competent authority of imminent threats or actual damage. Remediation plans must be submitted and approved by the authority. Country-level implementation varies significantly.
Regulation
Directive 2008/98/EC sets the basic framework for waste management across the EU. Relevant to contaminated sites because excavated soil may be classified as waste (including hazardous waste) depending on contaminant levels. The waste hierarchy (prevention, reuse, recycling, recovery, disposal) applies to contaminated soil management. End-of-waste criteria may allow treated soil to exit waste status.
Governing Body
European Commission. Transposed by each member state. National environment agencies regulate waste classification and disposal.
Trigger
Excavation of contaminated soil triggers waste classification requirements. Soil leaving a site must be classified using the List of Waste (LoW) and assessed against hazardous property thresholds. Movement of contaminated soil between sites may require waste transfer documentation.
Penalties
Set at member state level. Illegal disposal of hazardous waste carries criminal penalties in most EU countries under the EU Environmental Crime Directive (2008/99/EC). Fines typically range from tens of thousands to millions of euros.
Reporting
Waste transfer notes or consignment notes required for each movement. Hazardous waste must be tracked through the entire disposal chain. Record-keeping requirements typically 3-5 years depending on the member state.
Regulation
The Dutch Intervention Values (Interventiewaarden) are published by RIVM (National Institute for Public Health and the Environment) and form part of the Soil Quality Decree. The system uses Target Values (background/negligible risk) and Intervention Values (serious contamination threshold requiring investigation). Widely used internationally as reference screening levels, especially in regions without established local standards.
Look up Dutch Intervention Values
Governing Body
RIVM develops the values. Ministry of Infrastructure and Water Management sets policy. Provincial authorities and municipalities handle enforcement. Since 2024, transitioning to the Environment and Planning Act (Omgevingswet).
Trigger
Exceedance of Intervention Values indicates "serious contamination" requiring further investigation. Soil Quality Decree applies when soil is moved between locations. Land transactions typically involve soil quality assessments (NEN 5740 protocol).
Penalties
Administrative enforcement by municipalities (compliance orders, penalty payments). Criminal prosecution under the Economic Offences Act for illegal soil disposal or falsification of soil quality reports. Fines up to several hundred thousand euros.
Reporting
Soil quality reports must be submitted to the competent authority before soil movement. Serious contamination must be reported to the provincial authority. Urgent cases (risk to health or spreading contamination) require immediate action.
Regulation
Environmental Protection Act 1990 Part 2A establishes the contaminated land regime for England and Wales (equivalent provisions in Scotland under Part 2A as applied by the Contaminated Land (Scotland) Regulations 2005). Operates on a "suitable for use" approach:
  • Land is "contaminated" only if it poses significant harm or pollution of controlled waters given its current use
  • Soil Guideline Values (SGVs) and Category 4 Screening Levels (C4SLs) provide assessment benchmarks
  • Below C4SLs = land is not contaminated land under Part 2A
  • Above SGVs = further risk assessment needed, possible remediation
Planning-led remediation under NPPF (National Planning Policy Framework) handles most contaminated site cleanups through the development control process.
Governing Body
England: Environment Agency (EA) and local authorities. Scotland: Scottish Environment Protection Agency (SEPA). Wales: Natural Resources Wales (NRW). Local authorities are the primary regulators under Part 2A; EA handles "special sites" (e.g. MOD sites, nuclear sites).
Trigger
  • Local authority strategic inspection identifies contaminated land
  • Planning applications on potentially contaminated land (majority of cases)
  • Pollution incidents affecting groundwater or surface water
  • Part 2A determination by local authority (relatively rare - fewer than 100 determinations nationally)
Key Standards
C4SLs published for arsenic, benzo(a)pyrene, benzene, cadmium, chromium VI, lead, mercury and PFOS. SGVs for select substances. Generic Assessment Criteria (GACs) from CL:AIRE or other bodies are also widely used.
Look up UK SGV/C4SL values
Penalties
Remediation notices under Part 2A. Failure to comply: up to 20,000 GBP fine in magistrates' court. Environmental Permitting Regulations offences: unlimited fines and up to 5 years imprisonment. The "appropriate person" liability chain follows Class A (polluter) then Class B (current owner/occupier).
Reporting
No fixed reporting deadlines under Part 2A. Local authorities maintain a contaminated land register. Planning-led contamination reports follow the planning application timeline. Pollution incidents must be reported immediately to the Environment Agency.
Key Considerations
The EU does not have a Soil Framework Directive (the 2006 proposal was withdrawn in 2014). Contaminated land management is primarily governed by member state national legislation, with EU directives providing the overarching framework for waste and liability. Key variations:
  • Germany: Federal Soil Protection Act (BBodSchG, 1998) with Precautionary, Trigger and Action Values. Enforced by 16 Lander (state) authorities.
  • France: "Sites et Sols Pollués" methodology. Risk-based approach focused on site use rather than universal threshold values.
  • Italy: Environmental Code (D.Lgs 152/2006 Part IV). Screening Concentrations for residential and commercial land use.
  • Scandinavia: Nordic countries have their own guideline values (e.g. Sweden has generic and site-specific guideline values from the Swedish EPA).
Always verify the specific national regulations for the country where your site is located. EU-level directives set minimum standards, but member states often impose stricter requirements.
Regulation
The NEPM (2013 amendment) provides a national framework for assessing contaminated sites. Key components:
  • Health Investigation Levels (HILs) - screening values for soil contaminants by land use:
    • HIL A - Residential with garden / accessible soil (most conservative)
    • HIL B - Residential with minimal opportunity for soil access
    • HIL C - Open space such as parks and recreational areas
    • HIL D - Commercial / Industrial
  • Ecological Investigation Levels (EILs) - for protection of terrestrial ecosystems, derived from species sensitivity distributions
  • Health Screening Levels (HSLs) - for volatile contaminants in soil vapour
Look up NEPM HIL values
Governing Body
Federal: Department of Climate Change, Energy, the Environment and Water. The NEPM is implemented by state and territory EPAs. States may adopt NEPM values directly or set their own (stricter) guidelines.
Trigger
  • Property development or change of land use (state planning requirements)
  • Notification of contamination under state legislation
  • Environmental audit requirements (e.g. Victoria EPA mandatory audit conditions)
  • Due diligence for property transactions
Penalties
Enforcement is at the state level. Example penalties: NSW EPA fines up to AUD 5,000,000 for corporations for wilful or negligent pollution. Victoria EPA can impose civil penalties, clean-up orders and prohibition notices. Criminal prosecution possible for serious environmental offences.
Reporting
Contamination notification requirements vary by state. NSW: notify EPA within 24 hours of becoming aware. Victoria: complete preliminary risk screen assessment. Audit timelines set by state EPAs on a site-specific basis.
Overview
Each Australian state and territory has its own contaminated land legislation and EPA:
  • NSW: Contaminated Land Management Act 1997 (CLM Act). EPA NSW maintains a register of contaminated sites. Environmental auditors (accredited by EPA) provide independent assessment. Remediation orders issued under s.12.
  • Victoria: Environment Protection Act 2017 (replaces 1970 Act). EPA Victoria uses a risk-based approach. Environmental audit system provides regulatory closure. Preliminary Risk Screen Assessment (PRSA) triggers audit requirements.
  • Queensland: Environmental Protection Act 1994 and Environmental Protection (Contaminated Land) Regulation. Contaminated Land Register and Environmental Management Register maintained by DES. Site investigations required for notifiable activities.
  • Western Australia: Contaminated Sites Act 2003. Classification by DER/DWER: "contaminated - remediation required", "contaminated - restricted use", "remediated for restricted use" or "decontaminated". Mandatory reporting of known or suspected contamination.
Overview
WHO does not publish comprehensive soil quality guidelines equivalent to the Dutch Intervention Values or CCME SQGs. However, WHO guidance is important for contaminated site work in several ways:
  • WHO Drinking Water Quality Guidelines - often used as the basis for deriving soil-to-groundwater protection values. Many national soil guidelines back-calculate from WHO drinking water limits.
  • WHO Air Quality Guidelines - relevant for soil vapour intrusion assessments and ambient air quality targets near remediation sites.
  • WHO/IPCS Chemical Safety Publications - provide toxicological reference values (tolerable daily intakes, reference doses) used in site-specific risk assessment worldwide.
WHO guidance is most commonly applied in developing countries or jurisdictions without established national soil quality frameworks.
Key Considerations
  • ISO 18400 Series - International standards for soil quality and site assessment. ISO 18400-100 through 18400-206 cover soil sampling, characterization and investigation of contaminated sites. Provides a harmonized methodology recognized across jurisdictions.
  • Basel Convention - Controls transboundary movement of hazardous wastes (including contaminated soil). Prior informed consent required for cross-border shipment. Relevant when contaminated soil is exported for treatment or disposal.
  • Stockholm Convention on Persistent Organic Pollutants (POPs) - Bans or restricts production of POPs including PCBs, dioxins and certain pesticides. Contaminated sites with POPs may be subject to additional international reporting obligations.
  • Cross-border contamination - Groundwater plumes and river contamination that crosses national boundaries require bilateral or multilateral coordination. No single international enforcement mechanism exists; resolution relies on diplomatic agreements and international environmental law.
  • Developing countries - Many jurisdictions in Africa, Southeast Asia and South America are developing contaminated land frameworks. Dutch Intervention Values and WHO guidelines are commonly used as interim reference values in the absence of national standards.
