It is my understanding that this would not qualify since the hydrofluoric acid is classified as toxic and corrosive. Elementary neutralization can only be performed on wastes that exhibit the corrosivity characteristic. 

A good source for treatment methodologies is Margaret-Ann Armour's book called "Hazardous Laboratory Chemical Disposal Guide".
