1 Change # 5 Clergue Forest Management Inc. Operations Change Documentation for the ALGOMA FOREST Sault Ste. Marie / Wawa Districts, Northeast Region for the one-year period from April 1, 2012 to March 31, 2013 FMP Amendment Number N/A AWS Revision Number N/A Forest Management Activity: Harvest Renewal & Maintenance Access X Other Date of Proposal: June 14, 2012 Date Proposal to take effect: June 1, 2012 Nature of Values Change: The enclosed documentation is to provide the details of the changes for crossing in MOU 613 Turkey Lakes & crossing in MOU 734 Saddle. Crossing was proposed for installation in the Annual Work Schedule. Joint site inspection was completed on June 12, 2012 by Mike Thompson from Boniferro Mill Works and Gary Raines from the Ontario Ministry of Natural Resources. Since this crossing will be a bridge it does not have a timing restriction as no in water work is required. There is an existing crossing used to cross the creek. In order to maintain traditional access this bridge will be installed over the existing structure and removed at the completion of forest management activities. Crossing was a winter snow crossing removed prior to the spring freshet in the AWS, but is now needed to complete harvesting to the west of the creek. This is a short-term installation to be removed at the completion of forest management activities.
