The owner or operator shall maintain records in written or
electronic format sufficient to demonstrate compliance with each applicable
requirement for a minimum of five years, including but not limited
to:
(1) records in units of pounds per hour (lb/hr) of
production of carbon black for each grade of carbon black from each
carbon black production unit;
(2) twice daily records of sulfur content by weight
of the carbon black oil feedstock;
(3) daily records of sulfur content by weight of the
carbon black produced for each grade of carbon black produced by each
carbon black production unit;
(4) records of continuous carbon black oil feedstock
flow rates for each carbon black production unit;
(5) records of continuous tail gas volumetric flow
rates to each tail gas combustion device from each production unit
covered by §112.242 of this title (relating to Control Requirements);
(6) for each block one-hour period of operation of
a carbon black production unit, the required mass balance calculations
of emissions of sulfur dioxide (SO2)
from each EPN for those sources in operation without a continuous
emissions monitoring system (CEMS) for SO2;
(7) the continuous emissions monitoring data of emissions
of SO2 for each EPN in operation with
a CEMS for SO2;
(8) documentation of any period that emission limits
or standards were exceeded, and copies of exceedance reports submitted
to the appropriate Texas Commission on Environmental Quality regional
office; and
(9) copies of test reports for tests conducted in accordance
