AER OneStop + Alberta Environmental Records Viewer

Alberta Energy Regulator / Alberta Environment and Protected Areas

Environmental reports filed with Alberta regulators, including Phase 1 and Phase 2 Environmental Site Assessments, Remedial Action Plans, Reclamation Certificates, Records of Site Condition, and other regulatory environmental documents. Two sources feed this layer: the Alberta Energy Regulator (AER) OneStop public document system for upstream oil and gas sites, and the Environmental Records Viewer (ERV) from Alberta Environment and Protected Areas for contaminated sites under provincial environmental law. Phaseview extracts location data (Legal Land Descriptions) and metadata (consultant, date, report type) for each report, and links back to the original document on the regulator's own system rather than hosting a copy. The submission count and the date of the most recent sync are shown on the layer info badge.

Coverage
Province-wide regulatory submissions
Common Applications
  • Reviewing all historical environmental reports submitted for a property or surrounding area before a real estate transaction or development application.
  • Identifying whether a Phase 1 or Phase 2 ESA has previously been conducted at a site to avoid duplicating field work or to inform scope of new assessments.
  • Tracking remediation progress by viewing the sequence of reports (Phase 1, Phase 2, RAP, Reclamation Certificate) for a specific AER submission.
  • Identifying which environmental consultants have worked in a geographic area for procurement and peer review purposes.

Map MarkersReport SearchDetails Panel

Phaseview displays environmental reports as clustered map markers that expand on zoom, with click-through to full report details including metadata, consultant information, and a link to the original document on the issuing regulator's system. Reports are the core data layer of the platform and are always visible by default.

Field Surveillance Incident Inspection List

Alberta Energy Regulator (AER)

Field surveillance incident records from the Alberta Energy Regulator documenting spills, releases, and other environmental incidents reported by energy industry operators across Alberta. Each record includes incident date, substance released, volume, location coordinates, licensee, and resolution status. Updated monthly from AER spatial data files.

Coverage
All reported incidents province-wide
Common Applications
  • Identifying historical spill incidents near a project site during Phase I ESA area-of-concern identification and desktop review.
  • Assessing cumulative environmental liability by mapping all reported releases within a defined radius of a property.
  • Filtering incidents by substance type (crude oil, produced water, condensate) to evaluate specific contamination risks.
  • Supporting due diligence for property acquisitions by reviewing spill history and resolution status at a legal land description.

Layer InspectorMap LegendSidebar Filters

Rendered as color-coded point markers with three visualization modes (by substance, by age, by volume) and filtering by substance type, incident status, date range, and spill volume. Clicking a marker displays full incident details with a copy-all-spills-in-LLD export function.

Waste Management Facility Approvals

Alberta Environment and Protected Areas (EPA)

Waste management facility locations across Alberta sourced from Alberta Environment and Protected Areas (EPA) approvals data. Includes 222 current provincial landfills with operational status data (Active, Not Operating, Transfer Station), 139 federal/First Nations reserve landfills, and approximately 2,817 historical landfill sites. Facilities are classified by waste type and include approval information.

Coverage
Province-wide facilities
Last Updated

Common Applications
  • Checking proximity to active or closed landfills as part of a comprehensive Phase I ESA to identify potential off-site contamination sources.
  • Evaluating landfill gas migration risk for properties within 500 metres of active or historical waste disposal sites.
  • Identifying historical landfill locations that may not be apparent from current land use but could affect subsurface conditions.
  • Assessing environmental liability for properties near waste management facilities during real estate due diligence.
Used in Phaseview
Reconnaissance ToolComprehensive AnalysisLayer Inspector

Displayed as color-coded markers distinguishing operational status (Active, Not Operating, Transfer Station) with toggles for Current provincial, Federal/First Nations, and Historical facilities. The Reconnaissance Tool reports the nearest active Class II landfill with distance and bearing.

How consultants use these layers

  • 1Reviewing historical environmental reports submitted for a property before a real estate transaction or development application.
  • 2Identifying nearby spill incidents or contaminated sites that could affect a Phase I ESA area of concern.
  • 3Checking proximity to active or closed landfills as part of a comprehensive site assessment.
