P R O J E C T I N F 0 R M A T 10 N 1. Information on this plan is for erosion prevention and sediment control only. These notes are
comprehensive and should be applied according to the site-specific conditions for each individual ' ►
project. The Discharger is responsible for the installation and maintenance of a combination of
erosion and sediment controls by October 1st of each year for all applicable soil-disturbing
activities (clearing, grading, excavating) and on all exposed slopes throughout the entire site.
PROPOSED PROJECT ® The Discharger is also responsible for any discharges from subcontractors.
