Metal Protection. Ferrous metals are not stable in most
environments; they must be protected by isolating them from their
environments. Refer to Table 23 for applicable protective coatings for
corrosion control. Internal coatings of tanks and exterior coating of buried
tanks are not subject to this table. Interior coatings of tanks should suit
