National Pollutant Release Inventory (NPRI) Reporting & Compliance
Supporting Regulatory Compliance and Environmental Stewardship
Accurate reporting of pollutant releases is essential not only for compliance but for maintaining corporate transparency and community trust. The National Pollutant Release Inventory (NPRI) is Canada’s legislated, publicly accessible inventory of pollutant releases.
We provide comprehensive support to industrial, commercial, and municipal facilities to navigate the complexities of NPRI reporting. From initial threshold assessments to the final submission through Environment and Climate Change Canada’s (ECCC) Single Window Information Manager (SWIM), our team supports the accurate and timely submission of your data.

Why Choose Dillon for Your NPRI Reporting?
The NPRI tracks over 400 substances with varying reporting thresholds based on concentrations and quantities used. Our team of experts bring industry knowledge to simplify this process for you.
Collaborative Relationship
Our collaborative approach means we don’t just complete the report for you – we partner with your facility to integrate in-house knowledge, review data, and engage you at key decision points.
Multidisciplinary Expertise
We integrate our knowledge of industrial and manufacturing processes, waste management, wastewater treatment and air emissions to capture all reportable substances.
Regulatory Confidence
We stay ahead of evolving regulations (such as the new 2025-2027 reporting requirements and the addition of substances like PFAS) to help position your facility for compliance.
Data-Driven Accuracy
We utilize industry-standard emission factors and where available, site-specific data to provide robust calculations and release estimates.
Our NPRI Service Offerings
Applicability & Threshold Assessments
- Not every facility is required to report every year. We conduct thorough reviews of your operations, chemical inventories, fuel usage, and releases to determine if you meet the NPRI reporting criteria (Part 1-5 substances).
Emission & Release Calculations
- Our technical experts calculate releases to air, water, and land, as well as disposals and transfers for recycling. We utilize a range of estimation methods, including:
- Continuous Emission Monitoring Systems (CEMS)
- Mass Balance calculations
- Emission Factors (AP-42 and others)
- Engineering Estimates
Single Window (SWIM) Support
- We manage the technical side of the submission process, using the SWIM reporting system to input and submit the facility and substance release data before the June 1st deadline.
Compliance Audits & Gap Analysis
- If you have previously reported using in-house resources, we can perform a peer review of your past submissions to identify potential gaps, improve data quality, or optimize your reporting process for future years.
Integrated Environmental Compliance
- NPRI reporting often overlaps with other provincial and federal requirements. Dillon provides a holistic approach, aligning your NPRI data with:
- GHG Emissions Reporting
- Provincial Air & Noise Approvals (e.g., ECA in Ontario)
- Annual Operating Permit-required Reporting
Timeline & Cost
- Initial Review & Data Collection: 2–3 weeks
