Under Sun Acres Inc. - Environmental Compliance Approval (sewage)

This proposal from Under Sun Acres Inc. is for an amendment to the Environmental Compliance Approval No. 8046-BRPJE9 for expansion of a moving bed biofilm reactor (MBBR) wastewater treatment facility, to service the additional employment population of an expanding vegetable greenhouse, with warehouse, office and other accessory facilities located at 620 Mersea Road 10, in the Municipality of Leamington, Ontario.

The proposal is to expand an existing MBBR wastewater treatment process from 25 cubic metres per day to a rated capacity of 40 cubic metres per day. The existing and proposed works include pre-treatment facilities comprised of fats-oil-grease interceptors, flow equalization and primary sedimentation, together with expansion of an existing moving bed biofilm reactor and additional wastewater treatment process units, including alkalinity supplementation, pH adjustment, phosphorus removal through chemical precipitation, tertiary filtration, ultraviolet disinfection and continued gravity effluent discharge to surface water.

The proposed wastewater treatment facility is designed to achieve tertiary effluent quality required for dry-ditch discharge to the West Branch of Reid Drain at Highway 77, which is a municipal drain tributary to the Ruscom River. The Ministry of the Environment, Conservation and Parks (MECP) will require continued monitoring of the treated wastewater effluent discharge leaving the site.
