What are 'naturally occurring asbestos' (NOA) zones and are they present in Hawaii?

AA. NOA zones only occur on the mainland; not in Hawaii
BB. Naturally occurring asbestos is found in certain rock formations like serpentine (common on the mainland); Hawaii's basaltic volcanic geology makes NOA extremely unlikely, but imported fill material or construction aggregate should still be screened for asbestos in development planning✓ Correct
CC. All volcanic rock contains asbestos; disclosure is required for all Hawaii properties
DD. NOA concerns only apply to quarrying operations, not residential real estate

Explanation

Naturally occurring asbestos is associated with serpentine and ultramafic rock formations common in mainland states like California. Hawaii's geology is primarily basaltic volcanic rock, which does not naturally contain asbestos.
