N.J. Stat. § 54:4-1.12: Storage tank deemed real property

3. For the purposes of chapter 4 of Title 54 of the Revised Statutes and notwithstanding the provisions of R.S.54:4-1, a storage tank having a capacity of more than 30,000 gallons is deemed to be real property. The fact that products are mixed, blended, heated or subjected to a similar non-production process within a storage tank shall not in itself render that tank personal property.
