Consultation on Proposed Changes to NPRI for the 2014 Reporting Year Resulting From the NPRI Substance Review

• Bisphenol A : from 10 tonnes to 100 kg
• Hydrazine : from 10 tonnes to 1 tonne
• Isoprene : from 10 tonnes to 100 kg 
• Nonylphenol and its Ethoxylates : from 10 tonnes to 1 tonne
• Quinoline : from a Part 1A substance (10 tonne mass threshold) to a Part 2 substance (50 kg mass threshold for total polycyclic aromatic hydrocarbons, including quinoline, and 5 kg mass threshold for reporting quinoline itself)

One Proposed Addition :

• Ethanol, 2-(2-methoxyethoxy)- (CAS RN 111-77-3)

And several Proposed Deletions :

• Allyl chloride (CAS RN 107-05-1)
• C.I. Solvent Orange 7 (CAS RN 3118-97-6)
• 3-Chloro-2-methyl-1-propene (CAS RN 563-47-3)
• Ethyl chloroformate (CAS RN 541-41-3)
• 1-Bromo-2-chloroethane (CAS RN 107-04-0)

The consultation document is available from the CWWA website. CWWA encourages most facilities affected by this proposed changes to review the consultation document and provide comments to NPRI before Friday December 20, 2013 at: inrp-npri@ec.gc.ca

While some of these substances — for example bisphenol A — are undoubtedly present in trace amounts in wastewater streams concentrations fall well below even the revised threshold. The consultation document states that reporting is expected to significantly increase, but only from the industrial sectors directly using and manufacturing the chemicals.

Allan Mumby from EPCOR represents CWWA on the NPRI Working Group who met recently in Ottawa and monitors and provides input on proposed changes to the reporting requirements. He will be providing a summary of recent discussions for the next Bulletin.
