Transcript Slide 1
Keeping the Course to
Delisting
Niagara River RAP Implementers Workshop
April 10, 2013
The RAP Process
AOC Designation
Stage 1Define the problems
Stage 2Develop and implement the action plan
Stage 3- Complete actions
and monitor for recovery
DELIST
Water Quality Problems:
Beneficial Use Impairments
GLWQA
identifies 14 beneficial use
impairments (BUI) linked to degraded
water quality
BUIs are a common language for GLs
All RAPs select from same list of 14 BUIs
to describe problems
RAP must address each BUI to delist
14 Beneficial Use Impairments
Restrictions on fish and wildlife
consumption
Tainting of fish and wildlife
flavour
Degradation of fish and wildlife
populations
Fish tumours or other
deformities
Bird or animal deformities or
reproduction problems
Degradation of benthos
Restrictions on dredging
activities
Eutrophication or undesirable
algae
Restrictions on drinking water
consumption or taste or odour
problems
Beach closings
Degradation of aesthetics
Added costs to agriculture or
industry
Degradation of phyto/zoo
plankton populations
Loss of fish and wildlife habitat
Restrictions on Fish Consumption
MOE Study on Niagara R – still
consumption advisories (Hg, PCB, DDT)
Review of data for Welland R watershed
expected 2013
NRRAP must demonstrate that there are
no Canadian sources for ongoing
impairment in Niagara River
2008
Degradation of Fish and Wildlife
Populations
BUI
linked to habitat and contaminants
MNR currently assessing fish populations
Wildlife population assessment complete,
report to be written in 2013
Assessment may recommend fish habitat
projects
Degradation of Benthos
Benthic invertebrates
are an indicator of
degraded water
quality
Signals potential for
impact on food chain
Assessment nearing
completion
Eutrophication & Undesirable
Algae
BUI
will be assessed in 2013
Focus on Niagara R
Welland R Eutro Study 20
Will identify RAP vs “regional” actions
Beach Closings
Queen’s Royal Beach
remaining issue
Source is under
investigation
Expect resolution in
near future
Degradation of Phytoplankton and
Zooplankton Populations
Never
assessed
Linked to Eutrophication and Undesirable
Algae BUI
“Not Impaired” in US Area of Concern and
other “connecting channel” AOC
Loss of Fish and Wildlife Habitat
Interim assessment
done in 2012
Most targets reached
Binational GLFC team
forming for Niagara R
habitat work
Fish Population report
will flag habitat needs
