• When using a pump, the intake shall be controlled to prevent entry of fish and other aquatic wildlife (screen any water intakes or outlet pipes to prevent entrainment or impingement of fish as per DFO Freshwater Intake End-of-Pipe Fish Screen Guideline) and the Measures to Avoid Causing Harm to Fish and Fish Habitat as outlined on the DFO website; and
  
  
• When water is discharged to a watercourse, the water discharged shall be done in a manner that does not cause erosion or other damage to adjacent lands.

5.3.3 Requirements for Sediment and Erosion Control

Sediment and erosion controls are to be used for the duration of the work which include:

• Installation of effective erosion and sediment control measures before starting work to prevent downstream impacts;

• Design and implement erosion and sediment controls to contain/isolate the construction zone, manage site drainage/runoff and prevent erosion of exposed soils and migration of sediment to the waterbody, and ensure site is stabilized prior to removal following construction per OPSS 805;

• All exposed soils or disturbed areas that drain into a waterbody shall be managed to prevent sediment migration immediately after exposure or upon completion of the Work in or around the waterbody or on the waterbody bank;

• A temporary dam or series of check dams will be installed directly downstream of the point where the infilling of the drain begins in order to isolate the remaining downstream section;

• Regular inspection and maintenance of erosion and sediment control measures during the course of construction including repairs to erosion and sediment control measures if damage occurs;

• Removal of non-biodegradable erosion and sediment control materials once site is stabilized;

• Erosion and sedimentation control measures shall not be placed in watercourses unless otherwise specified in the Contract, or directed by the Contract Administrator; and

• A 200m stand-by supply of prefabricated light duty silt fence barrier, in addition to silt fence barrier which may be specified elsewhere in the Contract, shall be maintained at the Contract site prior to commencement of grading operations and throughout the duration of the Contract.

5.3.4 Requirements for Spill Response and Reporting

Requirements for spill prevention, response, reporting and notification should follow those outlined in the Environmental Management Plan (EMP) & Consultation Process Report (MH, 2015).
