Subject: Your query regarding Enoch First Nation press conference Good afternoon, The Department of National Defence has been working with the Enoch Cree Nation for many years on unexploded ordnance cleanup on the Yekau Lake Former Practice Bombing Range, a 520 Ha parcel of land approximately 18 kilometres southwest of Edmonton. Because the safety and security of the public is a priority for the Department of National Defence (DND) and the Canadian Armed Forces (CAF), DND will be contacting the Enoch Cree Nation for details on the discovery of this piece of ordnance. As background to this issue, the Yekau Lake Former Practice Bombing Range was used between 1942 and 1944 by the British Commonwealth Air Training Plan to train allied aircrews in navigation and bombing techniques. The most frequent type of practice munition used on British Commonwealth Air Training Plan (BCATP) sites, and the only type confirmed at Yekau Lake, was the 11.5 lb practice bomb (flash or smoke variety). The UXO and Legacy Sites Program has conducted extensive work at this site since 2006, including: an airborne geophysical survey of a 375 Ha area (2007) to look for metallic "hotspots" over a large area that could represent clusters of UXO or munitions scrap; groundbased electromagnetic surveys in 2009 and 2010 to confirm the extent of the bombing range, and; digging of sample of 533 metallic objects identified from the above geophysical surveys to ascertain whether these items were bombs or bomb components. The majority within the inner survey area were partial practice bomb components. The majority in the outer ring were nonmunitions metallic scrap (e.g., pop cans, etc.). The above program of work provided DND with the information required to conduct a risk assessment and develop a risk management plan for the site. The risk assessment consisted of an analysis of explosive hazard and potential for human interaction based on land use as well as the distribution, nature and extent of potential UXO. The risk assessment identified mitigation measures, primarily a limited clearance, that was to be conducted for public safety. During the summer of 2011, a limited clearance of the Yekau site was conducted to help reduce the UXO and to further inform the risk assessment process. Following all this work, a total of approximately 4,000 bomb fragments were removed. No intact training bombs were found, and no high explosives were found either. The site has since been reassessed as having a low UXO Risk. The DND UXO and Legacy Sites Program strives to provide the public with a safe and riskfree environment. However, limitations of existing UXO detection technology means that no UXO legacy site can ever be declared completely hazardfree, even after a clearance activity. The public should exercise caution whenever venturing into these areas. Objects that could be UXO should be reported immediately to local police. Further information regarding UXO safety can be found at www.uxocanada.forces.gc.ca. Regards, Tina Crouse ADM (PA) | SMA (AP) National Defence | Défense nationale

Subject: Your query regarding Enoch First Nation press conference  Good afternoon, The Department of National Defence has been working with the Enoch Cree Nation for many years on unexploded ordnance clean‐up on the Yekau Lake Former Practice Bombing Range, a 520 Ha parcel of land approximately 18 kilometres southwest of Edmonton. Because the safety and security of the public is a priority for the Department of National Defence (DND) and the Canadian Armed Forces (CAF), DND will be contacting the Enoch Cree Nation for details on the discovery of this piece of ordnance. As background to this issue, the Yekau Lake Former Practice Bombing Range was used between 1942 and 1944 by the British Commonwealth Air Training Plan to train allied aircrews in navigation and bombing techniques.   The most frequent type of practice munition used on British Commonwealth Air Training Plan (BCATP) sites, and the only type confirmed at Yekau Lake, was the 11.5 lb practice bomb (flash or smoke variety).  The UXO and Legacy Sites Program has conducted extensive work at this site since 2006, including:
