   (1)  Install all monitoring systems required under this section and § §  123.211—123.215 and the applicable provisions of Chapter 139, Subchapter C (relating to requirements for source monitoring for stationary sources) for monitoring mercury emissions, including all systems required to monitor mercury concentration, stack gas moisture content, stack gas flow rate and CO₂ or O₂ concentration, as applicable, in accordance with 40 CFR 75.81 and 75.82 (relating to monitoring of Hg mass emissions and heat input at common and multiple stacks).

   (2)  Successfully complete the certification tests required under §  123.211 (relating to initial certification and recertification procedures for emissions monitoring) and meet the other requirements of this section and § §  123.211—123.215 that are applicable to the monitoring systems required under paragraph (1).

 (f)  The owner or operator of each EGU shall comply with the monitoring system certification and other requirements of subsection (e) on or before the later of:

   (1)  January 1, 2009.

   (2)  Ninety EGU operating days or 180 calendar days, whichever occurs first, after the date on which the EGU commences commercial operation.

 (g)  The owner or operator of each EGU shall record, report and quality-assure the data from the monitoring systems required under subsection (e)(1) on and after the later of:

   (1)  January 1, 2009.

   (2)  Ninety EGU operating days or 180 calendar days, whichever occurs first, after the date on which the EGU commences commercial operation.

 (h)  The owner or operator of an EGU for which construction of a new stack or flue, installation of add-on mercury emission controls, a flue gas desulfurization system, an SCR system or a compact hybrid particulate collector system is completed after the applicable deadlines of subsections (f) and (g), shall:

   (1)  Comply with the monitoring system certification and other requirements of subsection (e).

   (2)  Record, report and quality assure the data from the monitoring systems required under subsection (e)(1).

   (3)  Comply with this section within 90 EGU operating days or 180 calendar days, whichever occurs first, after the date on which emissions first exit to the atmosphere through the new stack or flue, add-on mercury emission controls, flue gas desulfurization system, SCR system or compact hybrid particulate collector system.

 (i)  The owner or operator of an EGU that does not meet the applicable monitoring date in subsections (f)—(h) for any monitoring system required under subsection (e)(1) shall, for each monitoring system, determine, record and report maximum potential (or, as appropriate, minimum potential) values for:
