ACCOUNTING 
General 
In accordance with Section 4.2, a licensee or permit holder shall include the 
designated Base Year and corresponding baseline emission data, as outlined 
in the entity’s GHG Management Plan. 
Calculation and Estimation of emissions 
A 
licensee 
or permit 
holder 
shall adopt 
the following approaches 
or 
a 
combination of any for calculating and estimating emissions: 
Equipment Counts and Population Emissions Factor {EqC} 
For 
a 
specific 
type 
of 
equipment 
emission, 
relevant 
emissions 
factors 
prescribed by the Intergovernmental Panel on Climate Change (IPCC) shall 
be employed for equipment counts, or any other methodology approved by 
the Authority. 
Leak Surveys (LS) 
Leak detection survey shall be conducted using equipment such as, Optical 
Gas Imaging (OGI) cameras, organic vapor or toxic vapor analysers, infrared 
laser beam, acousiic leak detection instruments and any other equipment as 
may be approved by the Authority. 
Emissions Estimation and Quantification Requirements 
a. General Requirement 
ii. 
Operators shall adopt greenhouse gas (GHG) emissions estimation and 
quantification methodologies that are consistent with internationally 
recognized 
standards, 
including 
but 
not 
limited 
to 
the
