St. Clair ethanol plant

We operate the St. Clair ethanol plant, Canada’s largest ethanol facility, which opened in 2006 in the Sarnia-Lambton region of Ontario.

Beginning in 2014, health and safety data for the St. Clair ethanol plant is reported in the Refining & Marketing (R&M) performance data.

Footnote B:
Greenhouse gas (GHG) emissions are calculated using a facility-specific methodology which utilizes various reference methodologies that have been accepted by the relevant jurisdictions each facility is required to report its GHG emissions. Methodology has been followed where a jurisdiction has a prescribed one and if none exists, then the most applicable and accurate methods available are used to quantify each emission source. GHG emissions are consistent with what is reported to the Ontario government. The only exception is the use of the Intergovernmental Panel on Climate Change’s (IPCC’s) third assessment global warming potentials (GWPs). Our 2013-2017 Reports on Sustainability use IPCC’s fourth assessment GWPs.

The St. Clair ethanol plant’s wastewater treatment system, Bio-Methanator, produces methane bi-product that is sent to its dedicated flare, the Bio-Methanator Flare. The calculated emissions from this source are based upon ICM’s (ICM inc. designed the St. Clair ethanol plant) and additional derived emission factors, and assumed hours of operations as designed by ICM. The CO2e emissions from the Bio-Methanator Flare are included in the total GHG emissions and accounts for less than 0.10% of the total GHG emissions. The flare volumes from this source aren’t reported in our Report on Sustainability as the Bio-Methanator Flare emissions contributions are extremely low (0.10%) and are calculated based upon conservative assumptions.

Prior to 2014, waste that was reused, recycled and recovered was not included in the totals for hazardous and non-hazardous waste generated and was reported as an aggregated total. Beginning in 2014, in order to provide a more detailed breakdown of the waste streams created due to our operations, we have included this category of waste in both hazardous and non-hazardous total waste generated. In 2015, we added the categories of: non-hazardous waste incinerated and non-hazardous waste otherwise disposed, as a result of further refining our waste streams.

In general, waste volumes are dependent on activities conducted at site and can vary from year to year.

Hazardous waste is primarily generated from clean-out of trucks arriving at the ethanol plant. Volume is dependent on the condition of these trucks.

Reductions in 2012 were a result of process improvement with a contracted trucking company. In 2013, two spills of ethanol mixed with rainwater to the tank farm containment area contributed to a larger amount of hazardous waste generated. In 2014, hazardous waste volumes were influenced by the cleanup and disposal of a sulfuric acid tank leak into its containment area.
