Broaden the scope of the Dredging Activity Planning Registry

Context and project description

Since 2009, a planning registry for dredging activities conducted in the St. Lawrence is accessible on the Internet. It contains a list of dredging activities planned over the course of a given period (that the promoters choose to enter), maps of the location with project details, as well as information on the management and regulation of dredging. The goal is to facilitate the exchange of information among promoters and organizations involved or simply interested in these activities, upstream from the dredging projects. The objective is also to allow for mid- to long-term regional planning of dredging activities for the whole of the St. Lawrence. Lastly, this tool will facilitate the research of optimal solutions for difficulties that may arise from dredging.

With their project, those responsible are now broadening the scope of the Registry by adding various elements, such as best practice guides, downloadable reference documents in PDF format and an interactive decision-making diagram. In addition to indicating the steps to take, this diagram gives access using interactive features to various relevant federal and provincial documents, as well as those completed as part of the SLAP, to guide stakeholders in their approach.

Results

The Registry has been updated on an ongoing basis to ensure that the information is relevant and current. The publications on dredging prepared under SLAP have been posted online in the Registry. For example, in 2013 the guide titled  Ecological Risk Assessment of Open-Water Sediment Disposal to Support the Management of Freshwater Dredging Projects was published and then incorporated into the Registry.

In addition to providing access to various documents, the Registry has an interactive map that can be consulted to obtain information on dredging projects carried out along the St. Lawrence River. The proponents of dredging projects provide information on dredging activities on a voluntary basis. In 2014 and 2015, 11 dredging activities were listed in the Registry. In addition, some 30 dredging or sediment disposal sites can be viewed on the map; these sites located between Montreal and the Magdalen Islands consist of dredging projects reported by proponents. The Registry also contains a section on the laws pertaining to dredging projects in the St. Lawrence.
