Iverson Weed Management Plan <br />Lafarge proposes a multi-layered control plan to manage the site. Below you will find a chart with the <br />various common weed types found in this area and the planned treatment method. Lafarge reserves <br />the right to select herbicides that will most effectively treat the specified weeds as needed. Lafarge will <br />do monitoring of the site at a minimum of quarterly to ensure that weed control methods are effectively <br />being applied and followed per this plan. Any unique situations that occur in the field will be addressed <br />at that time in following this plan as closely as possible for the situation. All applications of mowing and <br />herbicide will be done with a 4-wheeler or hand sprayer depending on the location and access to the <br />treatment area. These applications will be applied per the schedule below, to address any regrowth or <br />new growth on the site. This schedule will continue until the weeds below are no longer a problem at <br />the site. Lafarge will be responsible for weed management upon commencement of operations. Any <br />weed invasion prior to operations is the property owner's responsibility. <br />Weed Type Cutting Controls Other.
