Data quality: National Pollutant Release Inventory
Environment and Climate Change Canada’s (ECCC) data quality management framework ensures that NPRI information meets the needs of data users.
- Facilities must report to NPRI by the annual deadline, typically June 1.
- The Canadian Environmental Protection Act, 1999 sets out penalties for companies that fail to report or that knowingly submit false or misleading information.
- ECCC staff help facility representatives understand NPRI reporting requirements and prepare accurate reports.
- ECCC checks the reports for inaccuracies and reporting errors, and may contact or visit facilities to verify or correct information.
- Accurate location coordinates for NPRI reporting supports air quality modelling as well as watershed and other analyses.
- Geographic data, using mapping software such as Google EarthTM, helps visualize facilities.
- ECCC staff use satellite imaging, legal property descriptions and other tools to validate the geographic information of facilities reporting to NPRI. Contact NPRI to correct any of this information.
- NPRI data quality management framework - the elements of NPRI data quality, and a summary of current and planned data quality initiatives.
- Using and interpreting NPRI data - Important considerations for NPRI analysis.
- Query tool - Search detailed information on pollutant releases (to air, water and land), disposals and transfers for recycling reported by facilities to the National Pollutant Release Inventory (NPRI) from 1994 to 2017
