Type of Watercourse Downstream Compliance Point Distance (1) Downstream Compliance Point Distance 2 Downstream Compliance Point Distance 3 Ponded systems such as lakes, pools, wetlands, and similar other waterbodies where velocities are less than 0.5 m/s the lesser of 30 metres, or the maximum surface dimension of the waterbody. Samples shall be taken at 30 m intervals around the circumference of the turbidity barrier 20 m from Compliance Point 1 (dependent on the size of the waterbody). Samples shall be taken at 30 m intervals around the circumference of the turbidity barrier 20 m from Compliance Point 2 (dependent on the size of the waterbody). Samples shall be taken at 30 m intervals around the circumference of the turbidity barrier wetted streams less than 10 metres wide 1 stream-width downstream 2 stream-widths downstream 3 stream-widths downstream wetted streams between 10 metres and 30 metres wide 30 metres downstream 60 metres downstream 90 metres downstream wetted streams greater than 30 metres but less than 60 metres in width 60 metres downstream 120 metres downstream 180 metres downstream wetted streams greater than 60 metres in width 90 metres downstream 180 metres downstream 270 metres downstream Note (1): In the event that a visually conspicuous plume exists, the Contractor shall measure total suspended solids at various locations across the watercourse, in accordance with the following: Samples must be taken from the middle of the plume. Samples must be taken as close to the source of the plume as possible (within safety limits). If the watercourse is less than 5 metres wide then only one measurement is required across the stream width. Measurement must be taken within the plume. If the watercourse is greater than 5 metres wide, measurement must be taken at a minimum of three locations across the watercourse; within the plume, half-way across the channel, and 2/3 of the channel width measured from the bank closest to the point where the discharge originated. Maximum Allowable Increase of Total Suspended Solids Visual Limits In the event a visually conspicuous plume exists, the Contractor shall cease all activities which have the potential to generate sediment in the watercourse. Compliance Criteria Criteria are set by the Canadian Council of Ministers of the Environment guidelines. The Contractors operations shall utilize equipment, labour, and procedures that ensure the
