Final Rule: Mandatory Reporting of Greenhouse Gases
What Must Be Monitoredfor Each Supplier of Petroleum Products?
For petroleum refineries, monitor these parameters...
~	Annual volume or mass of each petroleum
product and natural gas liquid (NGL)
(metric tons or barrels [bbl]) leaving the
facility, aggregated by each measurement
method used to determine quantity
~	Annual volume or mass of each petroleum
product and each NGL that enters the
refinery to be further refined or otherwise
used on site (metric tons or bbl), aggregated
by each measurement method used to
determine quantity
~	Annual volume or mass of each type of
biomass that enters the refinery and is co-
processed with petroleum feedstock
(metric tons or bbl), aggregated by each
measurement method used to determine
quantity
~	Volume of each batch of crude oil feedstock
used at the refinery (bbl)
~	Sulfur content of each batch of crude oil
feedstock at the point of entry at the
refinery
~	For blended biomass-based fuels, percent
volume of each product that is petroleum-
based
~	Percent of total mass that carbon
represents in the petroleum product or
NGL, and method of carbon share
measurement, if using Calculation
Method 2
~	Percent of total mass of each molecular
component in the petroleum product or
NGL, if using Calculation Method 2 and
gas chromatography
~ API gravity of each batch of crude oil
feedstock at the point of entry at the
refinery
~	Country of origin of each batch of crude
oil feedstock (if known)
~	Number of samples collected, and
sampling method used, if using
Calculation Method 2
~	Annual quantity of bulk NGLs (metric
tons or bbl) received for processing
~ Density of non-solid petroleum product or
NGL, and method of density measurement,
if using Calculation Method 2
(metric tons per bbl)

For importers and exporters of petroleum products and NGLs, measure these
parameters...
~	Annual volume or mass of each petroleum
product and NGL imported or exported
(metric tons or bbl), aggregated by each
measurement method used to determine
quantity
~	Percent of total mass of carbon in the
petroleum product or NGL, and method of
carbon share measurement, if using
Calculation Method 2
~	For blended biomass-based fuels, percent
volume of each product that is petroleum-
based
~ Density of non-solid petroleum product
or NGL, and method of density
measurement, if using Calculation
Method 2 (metric tons per bbl)
~	Percent of total mass of each molecular
component in the petroleum product or
NGL, if using Calculation Method 2 and
gas chromatography
~	Number of samples collected, and
sampling method used, if using
Calculation Method 2
