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 covered by §112.112
of this title (relating to Control Requirements); and
(6) for each block one-hour period of operation of
a carbon black production unit:
(A) records of the identification of each furnace on-line
each minute of each block one-hour period;

dioxide (SO2) as determined by §112.112
of this title during the block one-hour period, including any calculations
conducted under §112.112(b) of this title;
(C) records of all information identified in §112.113
of this title (relating to Monitoring Requirements) and the required
mass balance calculations of emissions of SO2 for

during the block one-hour period;
(7) 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
(8) copies of test reports for tests conducted in accordance
