GUIDELINES FOR MANAGEMENT OF GREEN HOUSE GASES (GHG) 
AND FUGITIVE EMISSIONS FROM MIDSTREAM AND DOWNSTREAM 
PETROLEUM OPERATIONS IN NIGERIA 
i. 
for 
a 
corporation: 
president, 
secretary, 
treasurer, 
or 
vice-president 
of 
the 
corporation in charge of a principal business function, or any other person who 
performs similar policy or decision-making functions for the corporation, or a duly 
authorized representative of the corporation 
if the representative 
is responsible 
for the overall operation of the source. 
ii. 
for a partnershio 
or sole proprietorship: 
a general partner or the proprietor, 
respectively. 
Compressor: A compressor is 
a mechanical device that increases the pressure of a gas 
by reducing 
its volume. 
It accomplishes this by transferring energy to gas, typically 
through mechanical work. 
Compressor station: 
A compressor station is a facility which helps the movement of gas 
such natural gas, methane, ethylene, hydrogen, ammonia and carbon dioxide, from 
one location to another in a pipeline system. 
Critical Component: Component that would require the shutdown of a 
critical process 
unit if the Component was shut down or disabled. 
Critical Process Unit: Process unit that shall remain in service because the shutdown of 
the unit could affect the safety and/or reliability of the natural gas supply system. 
. Emission Factor: means a coefficient that quantifies the emissions or removals of a gas 
per unit activity. Emission factors are often based on a sample of measurement data, 
averaged to develop a representative rate of emission for a given activity level under 
a given set of operating conditions. 
. 
Emission Intensity: An emission intensity (also carbon intensity or Cl.) 
is the emission rate 
of 
a given pollutant relative 
to the intensity 
of a specific activity, 
or an 
industrial 
production process; for example, grams of carbon dioxide released per megajoule of 
energy produced, or the ratio of greenhouse gas emissions produced to gross domestic 
product (GDP). Emission intensities are used to derive estimates of air pollutant or 
greenhouse gas emissions based on the amount of fuel combusted, the number of 
animals 
in animal husbandry, 
on industrial production 
levels, distances traveled 
or 
similar activity data. 
. 
Facility: Any building, structure, 
or installation to which these guidelines apply, and 
which has the potential to emit methane.
