turbines were undersized relative to the reactor power. Inverhuron Provincial Park, 1950–present OPG owns the nearby 288 ha Inverhuron Provincial Park on Lake Huron, bordering Inverhuron, 14 km north-east of Kincardine, which is not part of the Bruce site proper, and leases it to the Ontario Ministry of Natural Resources. As a condition of the operating licence for Bruce Nuclear, OPG retained a 914 m radius exclusion zone in the northwest corner of the park. After operating over 25 years the park campground was phased out in 1976, because of safety concerns related to the heavy water production. When heavy water was no longer produced, the park campground was allowed to re-open in 2000 on the same spot. Eagles The heated water released back into Lake Huron by the plant prevents the surrounding shoreline from freezing over during winter and attracts an inordinate concentration of lake fish, which in turn attracts droves of bald eagles wintering in the area. Numbers peak around late February to early March and it is not uncommon for visitors to observe several dozen eagles in and around the general vicinity of the plant at any given time during these months. Security and safety In 1977, three Greenpeace activists canoed into the site to demonstrate the lack of security. On 23 September 2001, a man whose boat capsized on Lake Huron near the Bruce complex squeezed through a gate, entered an office building and phoned for help—all undetected. Before the 2001 September 11 attacks, mandate of the security team was to delay attackers for 17 minutes, until local police could respond. Reliance was on passive measures such as fencing and locks. The "transformed" post-9/11 security team is described as being larger than the police force of the city of Kingston, i.e. equivalent to the force of a city of 100,000. Force members are permitted to carry firearms, and have powers of arrest. The force possesses armoured vehicles, water craft, and the plant is now triple-fenced. In May 2008, the Bruce Nuclear Response Team (NRT) won the U.S. National SWAT Championship (USNSC), defeating 29 other teams from 4 countries, the first time a Canadian team won an international SWAT event. They won again in 2009, 2010, and 2011. After 9/11, tours of the plant area were discontinued, although there is a visitor centre outside of the site. According to the Bruce County emergency plan, "The Municipality of
