Soil standards
Vapour standards (parkades)
Soil relocation agreements
Sediment criteria will become standards
Will be updating technical guidance and
protocol documents
New protocols: leachate, carcinogenic
substances, CSST
Updated protocols: 2, 4, 6, 11, 12, 13, 16, 17,
18
Administrative guidance: 3, 5, 10
New lab methods
New contaminants of concern
Will be publishing errata throughout the
year
Schedules of CSR (2016)
Schedule 1 – Site Profile, Summary of Site
Condition
No Change
Schedule 2.1 – Protected Areas
Schedule 3.1
Part 1 – Matrix Numerical Soil Standards
Part 2 – Generic Numerical Soil Standards – Human
Health
Part 3 – Generic Numerical Soil Standards –
Ecological Health
Schedule 3.2 – Generic Numerical Water
Standards
Aquatic, Irrigation, Livestock, Drinking Water
Schedule 3.3 – Generic Numerical
Vapour Standards
Schedule 3.4 – Generic Numerical
Sediment Standards
Changed from Criteria
Residential Landuse
High density (RLHD):
A multiple use dwelling of three or more storeys
An institutional facility in a building of three or
more storeys
Playgrounds or growing vegetables is prohibited
Low density (RLLD):
A single residence
A multiple use dwelling of less than three storeys
An institutional facility in a building of less than
three storeys
Wildland Landuse
“The use of land for a primary purpose other
than an agricultural, commercial, industrial,
urban park or residential land use”
Natural Wildland – a protected area defined
in Schedule 2.1
e.g. Park, ungulate winter range, ecological
reserve, wildlife management area etc.
Currently 17 areas
Reverted Wildland – a wildland not listed in
Schedule 2.1
Natural Wildland more protective than
Reverted Wildland
Reverted Wildland targets an EC25 level of
ecological impact
i.e. Identical to agricultural/urban parkland
values
Natural Wildland targets an EC15 level of
ecological impact
i.e. Approximately 40% more strict than
Reverted Wildland
Industrial, commercial and RLHD are set to
EC50
Water Standards
Now listed in Schedule 3.2
Updated some old numerical standards
with toxicity based standards
Updated toxicity data
All drinking water standards now toxicity
based
Updated water transport model
Tweaked the formulae for calculating
standards
Aquatic Life Standards:
8% less stringent
5% more stringent
87% no change
Drinking Water Standards:
16% less stringent
19% more stringent
66% no change

Soil Standards
Previously in Schedules 4, 5, and 10
Consolidated in Schedule 3.1, Parts 1, 2,
and 3
Part 1 – Matrix standards
41 substances vs. 22 previously
Part 2 – Generic, Human Health
Part 3 – Generic, Ecological
Updated the partitioning model:
Modified soil type  slower groundwater
velocity
Modified some partition co-efficients
Changed leaching tests
Adopted a 2-dimensional steady-state
solution for saturated transport  lower
standards for some inorganic compounds
(Cd, Cu, Pb, Zn)
Updated biodegradation rates  lower
standards for BTEX
Excluded decay for PCE, TCE

Vapour Standards
Developed vapour standards for parkades
Not a defined landuse under CSR
Parking of multiple motor vehicles, excluding
residential properties
Enclosed building/storey of a building
Tweaked the exposure terms
AL/RL/PL – ET = 1.0 (i.e. 24/7/365 exposure)
CL – ET = 0.33
IL – ET = 0.11
Parkade – ET = 0.125
Soil Relocation
Agreements
Procedural and definition changes
Removed Schedule 7
If soil is contaminated, based on the source site, a
SRA will be required
For receiving site: use the lowest applicable
landuse standards
Can use local background concentrations
Can compare leachate tests to water quality
standards
Can use risk-based standards
Interim step, looking at new system
New & Emerging
Contaminants
Some brand new substances, some
changed due to new toxicity data or
fate/transport data
Adopted some from federal guidelines
