Vv.
Leak Detection and Repair (LDAR): Operational best practice designed
to identify
aa.
equipment, including its components, from which leaks occur or may occur that need
to be repaired ina given period in order to reduce and control emissions.
. Level: This is the different levels of reporting as established by OGMP, used to quantify
methane emissions. There are currently five
(5) levels based on OGMP 2.0, with the
following requirements:
i.
Level
1- requires reporting of a single emission value for the entire company
USING generic emission factors
i.
Level
2- requires reporting by segment (Upstream, Midstream, Downstream)
and emission type (Venting, Fugitive Losses, Flaring, Energy/Combustion),
iii.
Level 3- requires companies to create a granular emission inventory based on
equipment level information and generic emission factors.
iV.
Level 4 requires operators to build on the equipment inventory by conducting
measurements to update generic emission factors with measurement-based
emission factors and
Vv.
Level 5 requires companies to conduct top-down site-level measurements to
reconcile with the bottom-up source-level emissions inventory created in Level
4. For the current version It consists of five reporting levels, with the highest level
(Level 5) requiring that companies reconcile their source-level (Level 4) emission
inventories with measurements at the site level.
Licensee:/ permit holder: Any
entity,
including
an owner
or contractor,
having
operational control of components or equipment, including leased, contracted, or
rented components and equipment.
Lit Flare: adequate combustion: A flare with adequate combustion, operated with no
visible emissions, except for periods not exceeding a
total of 5 minutes during any
consecutive hours.
Lit! poor Combustion
(sputtering, smoking,
etc.):
Is one
that does
not meet
