(a) The owner or operator of any sulfuric acid plant subject to the provisions of §112.41(b) of this title (relating to Emissions Limits) shall conduct a complete visual inspection of all applicable emission control devices at least once per calendar year to ensure physical integrity and proper operation of the control system.
(b) The owner or operator of any sulfuric acid plant subject to the provisions of §112.41(b) of this title (relating to Emissions Limits) shall maintain the following records for two years and make available to authorized representatives of the Texas Air Control Board and/or local air pollution control agencies, upon request:
  (1) the average monthly sulfuric acid mist emissions calculated using the most recent stack test and expressed as pounds of sulfuric acid mist per ton of 100% sulfuric acid produced;
  (2) the results of annual inspections as required by subsection (a) of this section;
  (3) readings from a device for the continuous measurement of the pressure differential between the inlet and outlet gas streams of any fiber mist eliminator:
    (A) immediately following each annual inspection of the control device required by subsection (a) of this section and all other process start-ups in order to establish a reference pressure differential indicative of a properly functioning control device; and
    (B) at least once per calendar month in order to indicate the relative operating condition of the control device;
  (4) the emissions testing/or corrective actions performed in response to excessive variations in the observed pressure differential, to malfunctions detected during inspections of the control device, or to Texas Air Control Board requests.
