|(a) For purposes of this section, a source's baseline is defined
as the annual emissions that are calculated assuming full compliance with
the adopted requirements of this chapter and using data representative of
actual operations in 1990 or thereafter for all variables necessary to calculate
annual emissions for the identified source.
(1) For an alternate means of control (AMOC) application exclusively
utilizing a source that existed prior to January 1, 1990, the AMOC application
shall use data representative of actual operations in 1990.
(2) For an AMOC application utilizing a source that was created
on or after January 1, 1990, the AMOC application shall use data representative
of actual operations for the two years prior to the application for the AMOC,
or other representative years, as determined by the executive director.
(3) For an AMOC application utilizing a source exempted from
this chapter or with no applicable adopted requirements, or for a source whose
actual annual emissions were less than the annual emissions calculated assuming
full compliance with the adopted requirements, calculations will be based
on actual annual emissions.
(b) The AMOC applicant shall determine annual emissions limits
for each source included in the AMOC plan by utilizing the best available
data and good engineering practice, which may include the use of statistical
techniques to address variations in the data.
(c) For any source not controlled as otherwise specifically
required by this chapter where an applicable adopted requirement exists, the
AMOC applicant shall calculate credits needed by subtracting the source's
baseline from the source's annual emissions limit under the AMOC plan. This
difference shall then be multiplied by the appropriate factor in §115.911(3)
of this title (relating to Criteria for Approval of Alternate Means of Control
Plans), to determine the credits that must be generated by other sources.
(d) For a source controlled beyond the requirements of this
chapter, or for a source exempted from or with no applicable adopted control
requirement in this chapter, the AMOC applicant shall calculate the amount
of emission reduction credits generated by subtracting the source's annual
emissions limit under the AMOC plan from the source's baseline, less any reductions
that are generated for purposes discussed in §115.911(6) of this title.
(e) For all sources included in the AMOC plan, the AMOC applicant
will sum the total of credits needed and the total of credits generated to
establish that the credits generated exceed the credits needed.
(f) The maximum potential to emit shall be the maximum daily
emissions that the source could emit subject to any physical, operational
and regulatory limitations.
