Tin stabilizers in the vinyl industry: environmental performance agreement 2008 overview
This environmental performance agreement (the agreement) was in effect from March 10, 2008 to March 9, 2013.

The objective of the Environmental Performance Agreement Respecting the Use of Tin Stabilizers in the Vinyl Industry is to prevent the release of mono- and di-organotin tin stabilizers to the environment, in quantities or concentrations above an acceptable level, through the full implementation of the Guideline for the Environmental Management of Tin Stabilizers in Canada (the guideline) by all vinyl compounding facilities using tin stabilizers in Canada. This guideline was prepared by the Vinyl Council of Canada (VCC), the Tin Stabilizers Association (TSA), and tin stabilizer industrial users. The objective of the Guideline is to prevent the release of tin stabilizers to the environment by ensuring that these substances and their packaging materials are handled, stored, used and disposed of in a responsible manner.
The agreement was negotiated between Environment and Climate Change Canada (ECCC), the VCC and the TSA.
All facilities participating in the agreement completed their annual compliance report on handling practices of organotin stabilizers using the appendix G form for each reporting year. The reports from participating facilities were reviewed and consolidated by the VCC to produce an annual conformance report provided to ECCC for each reporting year.
The VCC completed and submitted to ECCC an update of annex B of the Guideline, Report on Tin Stabilizer Sold in Canada for the year 2011.
Overall, the guideline was implemented before the site verification by the majority of the facilities based on their best knowledge and understanding of the guideline. All areas for improvement that were identified during the site verifications were addressed by all of the facilities. Six action plans have been developed, and all have been fully implemented.
Over the lifetime of the agreement (from March 2008 to March 2013), each of the 33 participating facilities were subject to a site verification conducted by representatives from ECCC and the VCC. The site verifications confirmed that the 33 facilities using tin stabilizers have in place the procedures and practices recommended in the guideline, and therefore have fully implemented the guideline.
Performance measurement of the agreement shows success in meeting the objective of preventing the release of tin stabilizers. It also confirmed the risk assessment assumption that if preventive measures are in place, tin stabilizers are non-toxic.
Yearly progress reports on the site verifications from 2009 to 2013 are available upon request.
In 2004, the VCC and TSA introduced a voluntary tin stabilizer handling guideline to prevent the release of tin stabilizers to the environment by ensuring that these substances and their packaging materials are handled, stored, used and disposed of in a responsible manner. On November 18, 2005, ECCC proposed developing an agreement with the VCC and TSA to ensure full industry adherence with the guideline.
On April 23, 2007, ECCC published a Draft Follow-up to the 1993 Ecological Risk Assessment of Organotin Substances on Canada's Domestic Substances List. The draft assessment report concluded that the actions implemented by the vinyl industry have reduced the potential for releases of mono- and di-organotins to levels that are not of concern to the environment. These actions are codified in the guideline prepared and implemented by the VCC and TSA. On August 8, 2009, the final Follow-up to the 1993 Ecological Risk Assessment of Organotin Substances on Canada's Domestic Substances List concluded that mono- and di-organotins do not meet the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999 and are therefore concluded to be not toxic.
ECCC worked with industry between 2006 and 2008 to establish an agreement. The purpose of the agreement was to prevent the release of tin stabilizers to the environment in quantities or concentrations above an acceptable level.
The draft agreement was posted on ECCC's agreement website for a 60-day public consultation period, which ended on June 22, 2007. The only comments received pertained to general questions of clarification. As a result, no revisions were made to the draft agreement.
