  - (2) For tanks subject to [§ 63.7886(b)(1)(ii)](/cfr/40/63.7886.md?p=b-1-ii) and not using Tank Level 2 controls, meeting the requirements in paragraphs [(b)(2)(i)](#b-2-i) and [(ii)](#b-2-ii) of this section.
    - (i) Keeping records of the maximum HAP vapor pressure determined according to the procedures in [§ 63.7944](/cfr/40/63.7944.md) for the remediation material placed in each affected tank.
    - (ii) Performing a new determination of the maximum HAP vapor pressure whenever changes to the remediation material managed in the tank could potentially cause the maximum HAP vapor pressure to increase to a level that is equal to or greater than the maximum HAP vapor pressure for the tank design capacity specified in Table 2. You must keep records of each determination.
