PETROLEUM OPERATIONS IN NIGERIA

ii. 
Unstable flame occasioned by low gas volume or pressure for the flare 
design. 
Data Management 
A licensee or permit-holder shall keep records of 
all equioment generating 
emissions 
from 
each 
vent, 
including 
detailed 
documentation 
of 
venting 
operations from pressure vessels, pipelines, and storage tanks, capturing gas 
composition, volume, duration, and reason for release. 
Reporting 
A 
licensee 
or permit-holder 
shall 
submit 
an 
annual 
report 
demonstrating 
compliance and record of any deviations, accompanied by certification of the 
truth and accuracy of report signed by a competent person, not later than the 
first quarter of the preceding year. 
Flare Efficiency 
Operational Requirements 
Any gas flared shall be combusted 
in an auto-igniter or continuous pilot light 
with 
a 
design 
Destruction 
Removal 
Efficiency 
(DRE) 
of 
at 
least 
98% 
for 
hydrocarbons. 
Calculation of 98% DRE shall not include flare downtime for 
maintenance. 
Monitoring 
A licensee or permit-holder shall conduct the annual test of the auto-igniter to 
ensure: 
a. 
Its operability or the annual observation of continuous pilot light to ensure it 
is independently lit. 
b. The flare at the time of LDAR inspection is observed, to confirm 
if it is 
lit or 
not.
