What are roadway drain valves?

200

Volumes of effluent over this limit are prohibited from being released under the ECA (Environmental Compliance Approval).

200

For significant leaks to air which can endanger the environment, equipment, or personnel, these shall be operated to stop flow to the plant.

What are the ESVs (emergency shut off valves)?

200

The E2 plan requires this exercise, annually.

What is a drill or tabletop exercise?

300

A discharge into the natural enviornment that is not likely to enter any waters, does not have the potential to cause adverse effects, and whose quanity, quality and circumstances are captured in a plan.

What is a non-reportable spill?

300

These must be closed or ensured closed immediately if a spill is identified.

300

This testing must be completed 9.9 hours after a liquid spill that may have entered the SWRP (Storm Water Retention Pond).

What is acute lethality testing? (toxicity testing)

300

What is a pollutant?

400

This laboratory located in Point Edward completes acute lethality testing for GEC.

What is Nautilus Environmental?

400

After a spill, if there is imminent risk of overflow from the SWRP (Storm Water Retention Pond) to this place before water testing results have been confirmed, it must be reported.

What is the emergency spillway?

400

An unplanned full release of this container is reportable.
