  2.1.4 Progress Metrics
•  

  ENV has concluded that there are no surface water intakes downstream of the spills.

  Groundwater wells downstream should not be affected.

• ENV created map of Chlorine setback and evacuation areas, including operational areas, staging areas, derailment and spills and fires.  PM 2.5 monitoring data were included for reference.

  ENV identified the proximity of spills to drinking water sources.  ENV concluded that no surface water intakes were downstream of the spills and that the nearby drinking water wells faced no immediate threat from the fills.

  ENV preparing sampling plans for next operational period
