3. Brownfield Regulations - Overview
▪ Extensive consultations were undertaken starting in 2007 on
amendments which affect four main areas:
1. New Phase I and Phase II Environmental Site Assessment (ESA)
and Record of Site Condition (RSC) procedures  more
transparency and integrity.
2. New streamlined (tier 2) risk assessment  timelier and more
cost-effective alternative to meeting generic standards.
3. Updated soil and groundwater standards  to reflect advances in
science, approximately 120 chemicals were updated.
4. Variable standards for quality of soil brought to RSC properties.
▪ Most of the amendments will come into effect on July 1, 2011.
▪ Transition rules allow the use of existing standards (up to Jan 1, 2013)
for projects significantly underway prior to Jan 1, 2011.
