The adjunct materials on this CD include a table with all five levels of the ECES structure. The descriptions, however, focus on the detailed elements of work established at Levels 3, 4, and 5. The descriptions indicate what items are included, and as appropriate, not included for the element and refer to those elements that are more applicable when performing environmental management work. Each detailed element also includes the phase number, a list of subordinate elements, supplemental notes as required, and units of measure (UOM).
