Contingency Measure Plan Elements
Section 212
Section 212.703 Contingency
Measure Plan Elements
a) All sources subject to this Subpart shall submit a contingency
measure plan. The contingency measure plan shall contain two levels of control
measures:
1) Level I measures are measures that will reduce total actual
annual source-wide fugitive emissions of PM-10 subject to control under
Sections 212.304, 212.305, 212.306, 212.308, 212.316(a) through (e), 212.424 or
212.464 by at least 15%.
2) Level II measures are measures that will reduce total actual
annual source-wide fugitive emissions of PM-10 subject to control under
Sections 212.304, 212.305, 212.306, 212.308, 212.316(a) through (e), 212.424 or
212.464 by at least 25%.
b) A source may comply with this Subpart through an alternative
compliance plan that provides for reductions in emissions equal to the level of
reduction of fugitive emissions as required at subsection (a) above and which
has been approved by the Agency and USEPA as federally enforceable permit
conditions. If a source elects to include controls on process emission units,
fuel combustion emission units, or other fugitive emissions of PM-10 not
subject to Sections 212.304, 212.305, 212.306, 212.308, 212.316(a) through (e),
212.424 or 212.464 at the source in its alternative control plan, the plan must
include a reasonable schedule for implementation of such controls, not to
exceed two (2) years. This implementation schedule is subject to Agency review
and approval.
