Marmora Clean Energy Hub Project

Although the Marmora Clean Energy Hub Project is not situated within the Crowe Valley Conservation Authroity Watershed, the CVCA must consider the potential impact upon its local watercourses and waterbodies.  At the time of this submission the CVCA has been informed the dewatering of the mine site may result in significant discharge into the Crowe River.  As per Ontario Regulation 159/06 the CVCA has concerns the discharge may alter the dynanmics of the Crowe River from the point of discharge downstream to where the Crowe River empties into the Trent River system.  Not only is there possibly a water quantity issue the CVCA is cognizant the water temperature could be affected and water from a souce outside of the CVCA watershed may have an impact on flora and fauna in the Crowe River. 

The dewatering process may have an impact on CVCA's dam operations and decisions as staff manage the lower reach of the Crowe River.  This concern would be particularily relevent during unforseen high flows in the Crowe River.

The CVCA is also concerned the installation of transmission lines may have an impact on welands in the Crowe watershed.  This would be determined through the Ontario Regulation 159/06 application process once the route of the transmission line has been identified.

Without a groundwater study the CVCA is concerned the dewatering may influence the movement of groundwater in the CVCA watershed.

The CVCA is more than willing to discuss the above noted comments and recommends further study to ensure the best possible outcome for the CVCA watershed.
