Category C: Minimal level of investigation is required as part of the assessment and approvals process. For some Category C issues, which are construction based, it was considered acceptable for investigation and management planning to be primarily undertaken after the assessment and approvals phase, prior to construction, when greater detail regarding construction activities would be available. In these instances, commitments for the management of the issue during construction would be made during the assessment and approvals process (refer to discussion in Section 8.4). The category assigned to each issue was based on both the: and severity of the potential impact (Consequence). Complexity of the mitigation measures required to manage the potential impact. The description of each category is presented in Table 6 below. Table 6 Investigation Categories Investigation Potential consequence Complexity of mitigation category A High - Potential for extensive, long term Complex and detailed management impacts, significant assets or values measures required affected with enduring changes (including potential for benefits). Widespread community interest. B Medium - Potential for moderate Standard management measures are impacts, significant assets or values available that can be adopted with some may be affected over an extended time tailoring frame with some resultant changes (including benefits). Regional community interest. C Low - Potential for short term and Standard management measures are localised impact. Asset or values may be available. Routinely managed on temporarily affected but recovery equivalent projects expected. Local community interest. In selecting a consequence category, an impact was considered to have if it has a real or not “potential” remote chance of occurring (with the application of mitigation measures). It was assumed that where applicable standard mitigation measures applied on similar past projects would be used. Results Table 7 and Table 8 present the findings of the issues screening exercise for Part A of the project (Eastern Freeway to CityLink) and Part B of the project (CityLink to the Port of Melbourne). Parts A and B of the project were split up for this exercise in order to reflect potential staging.
