Construction Activity and Pollution Prevention

We have Project intending to be registered under LEED 2009 BD+C for major renovations. This is an existing building which will undergo major renovation work for the interiors, HVAC and a large extent of the external façade (structural systems). Can the Project be considered under LEED NC Major Renovations? And regarding the credit Construction Activity Pollution Prevention the query is as follows: The documentation for strategies/activities to reduce pollution from construction activities, should only focus on the renovation areas? Or should it, also encompass the activities implemented earlier, during the construction of the existing building? Thanks in Advance
