The owner or operator of an affected source category within
a plant in the Beaumont-Port Arthur, Bexar County, Dallas-Fort Worth,
El Paso, and Houston-Galveston-Brazoria areas shall comply with the
following inspection and monitoring requirements.
(1) All seals and covers used to comply with §115.142(1)
of this title (relating to Control Requirements) shall be inspected
according to the following schedules to ensure compliance with §115.142(1)(G)
and (H) of this title:
(A) initially and semiannually thereafter to ensure
compliance with §115.142(1)(G) of this title; and
(B) upon completion of repair to ensure compliance
with §115.142(1)(G) and (H) of this title.
(2) Floating roofs and internal floating covers used
to comply with §115.142(2) of this title shall be subject to
the following requirements. All secondary seals shall be inspected
according to the following schedules to ensure compliance with §115.142(2)(E)
and (F) of this title.
(A) If the primary seal is vapor-mounted, the secondary
seal gap area shall be physically measured annually to ensure compliance
with §115.142(2)(F) of this title.
(B) If the tank is equipped with a mechanical shoe
or liquid-mounted primary seal, compliance with §115.142(2)(F)
of this title may be determined by visual inspection.
(C) All secondary seals shall be visually inspected
semiannually to ensure compliance with §115.142(2)(E) and (F)
of this title.
(3) Monitors shall be installed and maintained as required
by this section to measure operational parameters of any emission
control device or other device installed to comply with §115.142
of this title. Such monitoring and parameters shall be sufficient
to demonstrate proper functioning of those devices to design specifications,
and include the monitoring and parameters listed in subparagraphs
(A) - (H) of this paragraph, as applicable. In lieu of the monitoring
and parameters listed in subparagraphs (A) - (H) of this paragraph,
other monitoring and parameters may be approved or required by the
executive director:
(A) for an enclosed non-catalytic combustion device
(including, but not limited to, a thermal incinerator, boiler, or
process heater), continuously monitor and record the temperature of
the gas stream either in the combustion chamber or immediately downstream
before any substantial heat exchange;
(B) for a catalytic incinerator, continuously monitor
and record the temperature of the gas stream immediately before and
after the catalyst bed;
(C) for a condenser (chiller), continuously monitor
and record the temperature of the gas stream at the condenser exit;
(D) for a carbon adsorber, continuously monitor and
record the VOC concentration of exhaust gas stream to determine if
breakthrough has occurred. If the carbon adsorber does not regenerate
the carbon bed directly in the control device (e.g., a carbon canister),
the exhaust gas stream shall be monitored daily or at intervals no
greater than 20% of the design replacement interval, whichever is
greater, or as an alternative to conducting monitoring, the carbon
may be replaced with fresh carbon at a regular predetermined time
interval that is less than the carbon replacement interval that is
determined by the maximum design flow rate and the VOC concentration
in the gas stream vented to the carbon adsorber;
(E) for a flare, meet the requirements specified in
40 Code of Federal Regulations §60.18(b) and Chapter 111 of this
title (relating to Control of Air Pollution from Visible Emissions
and Particulate Matter);
(F) for a steam stripper, continuously monitor and
record the steam flow rate, the wastewater feed mass flow rate, the
wastewater feed temperature, and condenser vapor outlet temperature;
(G) for a vapor combustor, continuously monitor and
record the exhaust gas temperature either in the combustion chamber
or immediately downstream before any substantial heat exchange. Alternatively,
the owner or operator of a vapor combustor may consider the unit to
be a flare and meet the requirements of subparagraph (E) of this paragraph;
and
(H) for vapor control systems other than those specified
in subparagraphs (A) - (G) of this paragraph, continuously monitor
and record the appropriate operating parameters.
(4) In the Beaumont-Port Arthur, Bexar County, and
Houston-Galveston-Brazoria areas, units used to comply with §115.142(3)
of this title shall:
(A) initially demonstrate a 90% reduction in VOCs by
using the methods in §115.145 of this title (relating to Approved
Test Methods); and
(B) measure on a weekly basis the total suspended solids
in the aeration basin of the biotreatment unit.
(5) All water seal controls shall be inspected weekly
to ensure that the water seal controls are effective in preventing
ventilation, except that daily inspections are required for those
seals that have failed three or more inspections in any 12-month period.
Upon request by the executive director, EPA, or any local program
with jurisdiction, the owner or operator shall demonstrate (e.g.,
by visual inspection or smoke test) that the water seal controls are
properly designed and restrict ventilation.
(6) All process drains not equipped with water seal
controls shall be inspected monthly to ensure that all gaskets, caps,
and/or plugs are in place and that there are no gaps, cracks, or other
holes in the gaskets, caps, and/or plugs. In addition, all caps and
plugs shall be inspected monthly to ensure that they are tightly-fitting.
