Southgate Renewables GP Inc., as general partner for and on behalf of Southgate Renewables LP - Environmental Compliance Approval (sewage)

This proposal is for an amendment to the Environmental Compliance Approval, ECA No. 6976 DD4KRQ for the development of an anaerobic digester and associated site infrastructure at 160 Eco Park Way, Southgate, Ontario.

The proposed works will recycle the source-separated organics from municipal green bin programs and other commercial organic residual materials through the anaerobic digestion process, converting these materials into biogas and digestate (organic fertilizer).

The biogas will be upgraded to renewable natural gas (RNG) for injection into the Enbridge gas distribution system, while the digestate will be beneficially reused by local agricultural operations to offset commercial fertilizer use. A comprehensive stormwater management strategy is proposed to meet applicable water quality and water quantity control requirements.

Roof drainage from buildings, drive surfaces, and tank containment areas will be collected via the storm sewer system and conveyed through an oil-grit separator prior to discharge to the stormwater management pond.

The stormwater management pond will be located on the south side of the site and is designed to provide both quantity and quality control. The pond will be maintained a minimum of 15 meters from the adjacent wetland in accordance with applicable setback requirements.
