What evidence decides caustic or alkaline waste?
The spent caustic must come from a petroleum-refining liquid-treating process and be used as feedstock for cresylic or naphthenic acid.
Land placement or speculative accumulation voids the exclusion. Other recycling doesn't remove D002 or a listing on its own.
Can caustic or alkaline waste be excluded another way?
Only specified refinery feedstock use qualifies, and only without land placement or speculative accumulation.
