Dear pl understand that
Aspect impact is assessement based on to the environment and Risk Assessment is to Occupational safety heatlth
if a aspect is identified and it has both environment and Occupational impact and you have to understand
all risk and impact are caused by same aspects vise versa
in my opinion to have seperate analysis is best

From New_Aspact_-_Impact(1).xls , can u please explain what is Category N/AN/E. Is it Normal.Abnormal/Emergency. Is my guess is correct.
