5 percent 0, for a minimum of 90 days (Michigan allows this minimum to be 60 
days for Jonathan apples). The Washington law allows 25 days to reach the 5 
percent O05 level if other fruits or vegetables are stored in the CA storage. 
Washington also specifies condition and maturity standards for CA apples. In 
addition, operators of CA storages are required to keep a daily record of the 
gas analyses of each CA room.
