Stormwater Management

For example, residents receiving stormwater management services are owed a duty.

Standard of care constantly evolvingA negligent act, or omission, is one that breaches the re-

quired standard of care. The standard of care applicable to the design of infrastructure is likely to be the standard of care at the time of the design. That said, it is possible and perhaps more likely, that actions other than the design of infrastruc-ture will be subject to a claim of negligence. ,QRQHFDVHZKHUHWKHGHFLHQFLHVRIWKHVWRUPZDWHUV\V-

Since inspections, maintenance, repairs and other process decisions may be ongoing, they can be judged against a more recent standard of care. This may include considerations of changing information and climate change. Relying on out-

dated standards or processes can be negligent, if new infor-mation suggests that they should be reconsidered. This is the case even if the standards and processes were not negligent before the new information came to light.

This does not mean that decision makers need to change all possible standards and processes and upgrade their entire infrastructure in light of climate change information. After

Toronto received more than 4,700 basement flood complaints during and after the July storm.

With a history that dates back over a century in Ontario, it would be easy to assume that the state of science and knowledge in waterpow-er development reached its apex some time ago. While it is certainly true that the sector is mature in its approach to the consideration and incorporation of social, environmental and economic values, there is always new information to be brought to future projects.

The Ontario Waterpower Associa-tion (OWA) is undergoing collaborative efforts to develop Best Management Practices (BMPs). Building on the cre-ation and implementation of the 2008 Class Environmental Assessment for Waterpower, the OWA has sought to continuously improve the advice pro-vided to proponents, regulators and oth-er interests.

Species at risk The OWAs BMPs initially focused

on species at risk, including lake stur-geon, American eel and channel darter. 6SHFLHVDW ULVN%03VVSHFLFDOO\DG-

dress the relationship between waterpow-er projects and a particular species and offer practical advice using science-based information. A common theme in these documents is the pathways of effects DSSURDFKWRWKHLGHQWLFDWLRQRISRWHQWLDOimpacts and appropriate mitigation strate-gies. In all cases, the BMPs are designed to inform decision making and act to sup-plement professional judgement.

The OWA has subsequently expand-ed its efforts to develop a series of 38 BMPs associated with facility construc-tion. These provide practical and cur-rent best practices that assist proponents and contractors in determining how to construct, rehabilitate or repair a wa-terpower facility in an environmentally responsible manner.

Facility construction The BMPs have also been designed

so that an entire BMP or portions of it

can be easily incorporated into project tender documents. Professionals work-ing on waterpower construction sites, including contractors, inspectors and FRQWUDFW DGPLQLVWUDWRUV ZLOO DOVR QGthis compendium useful as a reference document. Agency personnel involved in waterpower project design, review and permitting can also use them to help in the execution of their mandates.

Once again in partnership with key organizations, the Association has add-ed three new products to the series in 2014, with a focus on wetlands, migra-tory birds and water quality.

Wetlands and migratory birds This project explores the connection

between waterpower facility develop-ment and key considerations with re-spect to wetlands and migratory birds. The BMPs are structured both as stand-alone documents and also incorporated into the series on construction. Impor-tantly, the initiative brought together subject matter experts from Ducks Un-limited Canada (Ontario), the Canadi-an Wildlife Service and the Ministry
