1. Action Plan to Enhance the Comparability of Pollutant Release and Transfer Registers (PRTRs) in North America First published in 2002 Updated in 2005 Updated Oct. 2014

2. Public Meeting of the NAPRTR Project Toronto, Canada, 2012 Stakeholders from government, industry, NGOs, the public, and the media discussed key issues in PRTR reporting and provided recommendations and specific actions to enhance the comparability of PRTRs in North America.

3. Key Issues Identified 1.Differences in industrial sectors subject to reporting 2.Inconsistent application of NAICS (North American Industry Classification System) codes 3.Difference in the pollutants subject to reporting 4.Inconsistent PRTR terminology and definitions 5.Lack of harmonization among local, state/provincial and federal programs 6.Inconsistent data quality and reliability

4. Recommendations and Proposed Actions 1.Identify gaps in the application of stated criteria for the reporting of sectors and activities a.Review and compare national criteria for the inclusion of industrial sectors or activities to identify possible additions b.Establish a mechanism to share information on PRTR sector coverage and changes c.Conduct sector-based workshops to identify reporting gaps or issues relevant to a specific sector d.Adopt a phased-in approach for consideration of reporting of the identified sectors

5. Recommendations and Proposed Actions 2.Develop Consistency in the Application of NAICS Codes a.Undertake a coordinated review of sector definitions and assignment of NAICS codes to identify inconsistencies b.Develop a consistent cross-walk for different NAICS codes c.Agree upon the timing for adoption of an updated version of NAICS codes d.Work with the three PRTR programs to share best practices to ensure facility reporting of correct NAICS codes

6. Recommendations and Proposed Actions 3.Share information relative to the substances of common interest and meeting the criteria for inclusion a.Review national criteria for the listing of substances b.Compare national PRTR reporting requirements (including thresholds) c.Establish a mechanism to exchange toxicological assessment information d.Adopt a phased-in approach for expanding the list of pollutants that must be reported e.Explore opportunities to expand comparability in cases where the substance listings and thresholds remain different due to national needs and circumstances

7. Recommendations and Proposed Actions 4.Develop consistent PRTR terminology and definitions a.Conduct a coordinated review of national PRTR terminology and definitions b.Establish an equivalent PRTR nomenclature (via a cross-walk of terms) c.Assess particular reporting elements where an expanded scope of information would improving our understanding of the data (e.g., pollution prevention comments)

8. Recommendations and Proposed Actions 5.Work towards local, state or provincial, and federal data integration or harmonization a.Explore strategies to harmonize reporting requirements for sectors that are regulated under multiple jurisdictions b.Explore potential avenues of cooperation with counterparts of local, state or provincial, and federal programs for sharing data

9. Recommendations and Proposed Actions 6. Share information on data quality assurance methodologies and tools a.Conduct a coordinated review of national PRTR data quality control and quality assurance activities b.Develop a prioritized list of data quality issues c.Conduct a series of trilateral, sector-based workshops involving a training component, or other activities, to increase compliance, quality and consistency of PRTR reporting d.Establish partnerships with other agencies for sharing and use of sector-based data to support improvements in reporting

10. Additional Recommendations 7. Establish a North American “Challenge” program for industry champions of environmental performance 8. Ensure more accessible and usable information through spatial representation of PRTR data, added context and combination with other data 9. Establish partnerships among scientific organizations, health and environmental journalists, industry associations, academic institutions, others 10. Develop sustainable development plans, policies, and programs
