UL 142 AST to Property Line

Get contradicting information from NFPA 30 and 30A on minimum distance between UL 142 4,000 Gallon Double Wall Steel Aboveground Storage Tank for diesel fuel and nearest property line.

 

NFPA 30 Table 22.4.1.1(a) indicate this tank with "emergency relief venting to limit pressures to 2.5 psi" to be 2 times the valve of table 22.4.1.1(b) which says would be 15' so total distance would be 30'.

 

NFPA 30A Table 4.3.2.4 indicates this tank "meeting the requirements of NFPA 30" from lot line distance to be 100'.

 

Which is correct or am I reading the tables incorrectly?
