(a) Not
later than 14 days prior to the applicable compliance date under §
129.304(b) or
(c), the owner or operator of a glass melting
furnace subject to this section, §§
129.301-
129.307,
129.309 and
129.310 shall install, operate and
maintain continuous emissions monitoring systems (CEMS, as defined in §
121.1 (relating to definitions))
for NOx and other monitoring systems to convert data to required reporting
units in compliance with Chapter 139, Subchapter C (relating to requirements
for source monitoring for stationary sources) and calculate actual emissions
using the CEMS data reported to the Department. The owner or operator of a
glass melting furnace may install or operate, or both, an alternate NOx
emissions monitoring system or method, approved in writing by the Department or
appropriate approved local air pollution control agency.
(b) Data invalidated under Chapter 139,
Subchapter C, shall be substituted with the following if approved in writing by
the Department or appropriate approved local air pollution control agency:
(1) The highest valid 1-hour emission value
that occurred under similar source operating conditions during the reporting
quarter.
(2) If no valid data were
collected during the reporting quarter, one of the following shall be reported
to the Department or appropriate approved local air pollution control agency:
(i) The highest valid 1-hour emission value
that occurred under similar source operating conditions during the most recent
quarter for which valid data were collected.
(ii) The highest valid 1-hour emission value
that occurred under similar source operating conditions during an alternative
reporting period.
(3) An
alternative method of data substitution.
(c) Instead of data substitution, the
Department or appropriate approved local air pollution control agency may
approve an alternative procedure to quantify NOx emissions and glass
production.
(d) The owner or
operator of a glass furnace subject to this section shall submit to the
Department or the appropriate approved local air pollution control agencies
quarterly reports of CEMS monitoring data in pounds of NOx emitted per hour, in
a format approved by the Department and in compliance with Chapter 139,
Subchapter C, or a format approved by the appropriate approved local air
pollution control agencies.
(e) The
CEMS or approved monitoring system or method for NOx installed under this
section must meet the minimum data availability requirements in Chapter 139,
Subchapter C.
