Submissions on Enforcement Matters

What Is a Submission?

A submission is a written document filed by the public with the Secretariat asserting that Canada, Mexico or the United States is failing to effectively enforce its environmental law.

A submission is the first step in the Submissions on Enforcement Matters (SEM) process and can lead to the production of a Factual Record. A Factual Record is a type of investigative report that includes technical, scientific, and legal information as well as interviews with government officials and analysis from independent experts. It documents the environmental, legal, and/or public health aspects of the situation.

For more information, watch this short film about one community’s success using the SEM process.

Submission Success Stories

Cozumel

Summary: Environmental impact assessment process of a port development in Cozumel, Mexico did not address all relevant impacts.

Outcome: This submission lead to the first factual record issued by the Secretariat under the SEM process. The process not only had a direct impact on the construction of  the pier in Cozumel but also influenced the designation of the Cozumel Reef Marine Park as a protected area.

Submission Success Stories

Municipal Wastewater Drop Shafts

Summary: The submitter tried through several avenues to request information regarding enforcement of the Safe Drinking Water Act (SDWA) enforcement. Afterwards, they filed a submission which asserted that that sewer drop shafts constituted “underground injection wells” that fall under the Safe Drinking Water Act’s (SDWA) permitting scheme rather than the Clean Water Act’s (CWA) jurisdiction. Drop shafts generally transport municipal wastewater from shallow sewer lines to deeper tunnels as part of a city’s wastewater collection system prior to treatment.

Outcome: Thanks to the submissions process, the Submitter obtained not only a thorough review by the Secretariat but also a detailed and comprehensive analysis from the EPA on why the CWA, and not the SDWA, regulates this infrastructure system.

Submission Success Stories

Metales y Derivados

Summary: The submitters alleged that the owner abandoned the facility upon its closure and returned to the United States, leaving behind an estimated 6,000 metric tons of lead slag, waste piles of by-products, sulfuric acid, and heavy metals.

Outcome: A number of years after the publication of the Factual Record, the Submitter and local NGOs in Mexico and US, the Ministry of the Environment and Natural Resources (Secretaría de Medio Ambiente y Recursos Naturales, Semarnat), and the US Environmental Protection Agency joined efforts to finally clean up the site. These efforts, which the SEM process helped to bring together, concluded with the remediation of the site in 2009.

Submission Success Stories

BC Hydro

Summary: The Submitters alleged that the Canadian Government failed to ensure the protection of fish and fish habitat in British Columbia’s rivers from ongoing and repeated environmental damage caused by hydro-electric dams.

Outcome: The publication of the factual record resulted in improved public participation procedures in the environmental assessment process. This allowed for more comprehensive planning of water use and fish conservation efforts at BC Hydro facilities. This further increased our understanding of the interaction between hydroelectric operations and fish conservation.

Submission Success Stories

BC Mining

Summary: The submission addressed Canada’s alleged failure to protect fish and fish habitat from the impacts of the mining industry in British Columbia. Among other issues, the Factual Record addressed operations at the Britannia Mine.

Outcome: Through increased public participation and transparency facilitated by the SEM process, a new water treatment plant was developed at the mine. Since then, the cleanup of the Britannia Mine area has proceeded to the point where it is almost 100 per cent free of toxic runoff. Salmon have returned to the lower parts of the creek and resident fish are starting to recolonize the upper part of the creek. Shellfish are once again recolonizing what was once a barren seabed due to the acidic runoff.

Compliance Tracker

This tool has been established to provide the public with a resource to track compliance with the SEM process deadlines established under the North American Agreement on Environmental Cooperation, the Guidelines for Submissions on Enforcement Matters and Articles 24.27 and 24.28 of the Environment Chapter of the free trade agreement between Canada, Mexico and the United States (CUSMA, T-MEC, USMCA).
