Md. Code Regs. 26.11.17.07 - Plantwide Applicability Limit (PAL) - General
A. Applicability.
(1) The Department may approve the use of a
PAL for any existing major stationary source if the requirements in this
regulation are met.
(2) Any
physical change or change in the method of operation of a major stationary
source that maintains its total source-wide emissions below the PAL level meets
the requirements of this chapter and complies with the PAL permit if:
(a) It is not a major modification for the
PAL pollutant;
(b) It does not have
to be approved through Regulations .01-.03 of this chapter; and
(c) It is not subject to Regulation .02G of
this chapter.
(3) Except
as provided under §A(2) of this regulation, a major stationary source shall
continue to comply with all applicable federal and State requirements, emission
limitations, and work practice requirements that were established before the
effective date of the PAL.
B. Definitions. In Regulations .07-.09 of
this chapter, the following terms have the meanings indicated:
(1) "Actual PAL" means, for a major
stationary source, a PAL based on the baseline actual emissions of all
emissions units at the source that emit or have the potential to emit the PAL
pollutant.
(2) "Allowable
emissions" has the meaning stated in Regulation .01B(2) of this chapter, except
that this definition is modified as follows:
(a) The allowable emissions for any emissions
unit shall be calculated considering any emission limitations that are
enforceable as a practicable matter on an emissions unit's potential to
emit;
(b) An emissions unit's
potential to emit shall be determined using the definition in Regulation
.01B(21) of this chapter, except that the words "or enforceable as a
practicable matter" shall be added after "federally enforceable".
(3) "Continuous emissions
monitoring system (CEMs)" means all of the equipment that may be required to
meet the data acquisition and availability requirements of this regulation, to
sample, condition (if applicable), analyze, and provide a record of emissions
on a continuous basis.
(4)
"Continuous emissions rate monitoring system (CERMs)" means the total equipment
required for determining and recording the pollutant mass emissions rate (in
terms of mass per unit of time).
(5) "Continuous parameter monitoring system
(CPMs)" means all of the equipment necessary to meet the data acquisition and
availability requirements of this regulation to monitor process and control
device operational parameters (for example, control device secondary voltages
and electric currents) and other information (for example, gas flow rate,
oxygen or carbon dioxide concentrations), and to record average operational
parameter values on a continuous basis.
(6) "Major emissions unit" means an emissions
unit that emits or has the potential to emit:
(a) 100 tons per year or more of the PAL
pollutant in an attainment area; or
(b) The PAL pollutant in an amount that is
equal to or greater than the major source threshold for the PAL
pollutant.
(7) "PAL
effective date" means the date of issuance of a PAL permit or a revised PAL
permit, except that the PAL effective date for an increased PAL is the date an
emissions unit which is part of the PAL major modification becomes operational
and begins to emit the PAL pollutant.
(8) "PAL effective period" means the period
beginning with the PAL effective date and ending 5 years later.
(9) "PAL major modification" means any
physical change in or changes in the method of operation of the PAL source that
causes it to emit the PAL pollutant at a level equal to or greater than the
PAL.
(10) "PAL permit" means the
permit issued by the Department that establishes a PAL for a major stationary
source.
(11) "PAL pollutant" means
the pollutant for which the PAL is established.
(12) "Plantwide applicability limit (PAL)"
means an emissions limitation, expressed in tons per year, for a pollutant at a
major stationary source, that is enforceable as a practicable matter and
established source-wide according to Regulation .08B of this chapter.
(13) "Predictive emissions monitoring system
(PEMS)" means all of the equipment necessary to monitor process and control
device operational parameters (for example, control device secondary voltages
and electric currents) and other information (for example, gas flow rate,
oxygen or carbon dioxide concentrations), and calculate and record the mass
emissions rate (for example, pounds per hour) on a continuous basis.
(14) "Significant emissions unit" means an
emissions unit that emits or has the potential to emit a PAL pollutant in an
amount that is equal to or greater than the significant level for the PAL
pollutant, but less than the amount that would qualify the unit as a major
emissions unit.
(15) "Small
emissions unit" means an emissions unit that emits or has the potential to emit
the PAL pollutant in an amount less than the significant level for that PAL
pollutant, as defined in Regulation .01B(26) of this chapter or in the Clean
Air Act, whichever is lower.
