Current through Reg. 49, No. 28; July 12, 2024
(a) In the El Paso area as defined in §
											115.10 of
					 this title (relating to Definitions), the following monitoring and
					 recordkeeping requirements apply.
(1) The
					 owner or operator of a heatset offset lithographic printing press shall
					 install, calibrate, maintain, and operate a temperature monitoring device,
					 according to the manufacturer's instructions, at the outlet of the control
					 device. The temperature monitoring device must be equipped with a continuous
					 recorder and must have an accuracy of ±0.5 degrees Fahrenheit, or
					 alternatively ±1.0% of the temperature being monitored.
(2) The owner or operator of any offset
					 lithographic printing press shall install and maintain monitors to continuously
					 measure and record operational parameters of any emission control device
					 installed to meet applicable control requirements on a regular basis. Such
					 records must be sufficient to demonstrate proper functioning of those devices
					 to design specifications, including:
(A) the
					 exhaust gas temperature of direct-flame incinerators or the gas temperature
					 immediately upstream and downstream of any catalyst bed;
(B) the total amount of volatile organic
					 compounds (VOC) recovered by a carbon adsorption or other solvent recovery
					 system during a calendar month; and
(C) the exhaust gas VOC concentration of any
					 carbon adsorption system, as defined in §
													115.10 of
					 this title, to determine if breakthrough has occurred.
(3) The dryer pressure must be maintained
					 lower than the press room air pressure such that air flows into the dryer at
					 all times when the offset lithographic printing press is operating. A 100%
					 emissions capture efficiency for the dryer must be demonstrated using an air
					 flow direction measuring device.
(4) The owner or operator of any offset
					 lithographic printing press shall monitor fountain solution alcohol
					 concentration with a refractometer or a hydrometer that is corrected for
					 temperature at least once per eight-hour shift or once per batch, whichever is
					 longer. The refractometer or hydrometer must have a visual, analog, or digital
					 readout with an accuracy of 0.5% VOC. A standard solution must be used to
					 calibrate the refractometer for the type of alcohol used in the fountain. The
					 VOC content of the fountain solution may be monitored with a conductivity meter
					 if it is determined that a refractometer or hydrometer cannot be used for the
					 type of VOC in the fountain solution. The conductivity meter reading for the
					 fountain solution must be referenced to the conductivity of the incoming
					 water.
(5) The owner or operator of
					 any offset lithographic printing press using refrigeration equipment on the
					 fountain solution in order to comply with §115.442(a)(1)(A), (C), or (D)
					 of this title (relating to Control Requirements) shall monitor the temperature
					 of the fountain solution reservoir at least once per hour. Alternatively, the
					 owner or operator of any offset lithographic printing press using refrigeration
					 equipment on the fountain solution shall install, maintain, and continuously
					 operate a temperature monitor of the fountain solution reservoir. The
					 temperature monitor must be attached to a continuous recording device such as a
					 strip chart, recorder, or computer.
(6) For any offset lithographic printing
					 press with automatic cleaning equipment, flow meters are required to monitor
					 water and cleaning solution flow rates. The flow meters must be calibrated so
					 that the VOC content of the mixed solution complies with the requirements of
					 §
												115.442(a)(1)
					 of this title.
(7) The owner or
					 operator of any offset lithographic printing press shall maintain the results
					 of any testing conducted at an affected facility in accordance with the
					 provisions specified in §
												115.445 of
					 this title (relating to Approved Test Methods).
(8) The owner or operator of any offset
					 lithographic printing press shall maintain all records at the affected facility
					 for at least two years and make such records available upon request to
					 authorized representatives of the executive director, the United States
					 Environmental Protection Agency, or any local air pollution agency with
					 jurisdiction.
