   2. (B) Submit a report to the department:

      1. (i) containing the measurements required by 40 CFR 60.18(f)(1)* through 40 CFR 60.18(f)(5)*, as required by 40 CFR 60.8*; and
      2. (ii) within six (6) months of the initial start-up date.
   3. (C) Submit a semiannual report to the department of all periods recorded under 40 CFR 60.115b(d)(2)* in which the pilot flame was absent.

(f) The owner or operator of each vessel equipped with a closed vent system and control device meeting the standards of section 4 of this rule is exempt from the requirements of subsections (g) and (h).

(g) Except as provided in subsections (f) and (j), the owner or operator of each vessel with a design capacity greater than or equal to thirty-nine thousand (39,000) gallons storing a VOL with a maximum true vapor pressure greater than or equal to five-tenths (0.5) pound per square inch absolute (psia) but less than seventy-five hundredths (0.75) psia shall maintain a record of the maximum true vapor pressure of the VOL stored in each vessel including the following information:

   1. (A) An initial physical test of the vapor pressure.

   2. (B) A physical test at least once every six (6) months thereafter using one (1) of the following methods:

      1. (i) ASTM Method D2879-10**, Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope.
