Norris Construction Management Inc. - Environmental Compliance Approval (waste)

Norris Construction Management Inc. (NCM Inc.) is applying to amend the Environmental Compliance Approval No. 6469-ADXJVG issued for a waste disposal site for the processing of hydrovac slurry waste and dry soils including non-hazardous contaminated soils as a Class 1 Soil Management – Processing site. The amendment requested is to remove Condition 3.9 of the approval that required a groundwater and surface water assessment if a unlined storage pond is used to store process waters from the hydrovac slurry soils separation, and to allow for the installation and operation of a closed loop process water treatment plant that will have no discharge to the ground or surface waters.

The daily maximum waste volumes for hydrovac slurry would be in three phases:

• phase 1 allowing 300 cubic metres,
• phase 2 allowing 600 cubic metres, and
• phase 3 allowing for 900 cubic metres per day maximum

Maximum storage volumes for hydrovac slurry soils will be 1,230 cubic metres for phase 1, 2,460 cubic metres for phase 2, and 3,690 cubic metres for phase 3. Water removed from hydrovac slurry will be reused within the treatment process.

The daily maximum volume of dry non-hazardous soils would be 800 tonnes and a maximum storage volume of unprocessed soils of 2,500 tonnes. Dry soils would be blended with hydrovac slurry to separate soils to produce reusable stone, aggregates, sands and a fine soils filter cake. Soil materials (sands, fine soils) would be tested to determine soil quality for reuse or disposal depending on tested soil quality. Testing and end use destinations (reuse for construction, beneficial reuse sites, landfill) would follow the requirements of O. Reg. 406/19 and Excess Soil Standards.

This application requests to extend the hours of operation from Monday – Saturday, 7 am to 7 pm . Currently the hours allow for operation from 8 am to 5 pm. This application also requests that the facility be allowed to receive waste delivered by hydrovac trucks on an emergency basis after hours.

The waste management facility is located on a 1.75 hectares site at 200 Maple Creek Court, Ottawa, Ontario. Waste received would be generated by residential, municipal, industrial, commercial and institutional sources within a service area of Eastern Ontario.
