Current through Register Vol. 63, No. 3, March 1, 2024
Natural gas suppliers and in-state producers required to
register and report under OAR 340-215-0030(4) must:
(1) Report the information required including
the volume (Mscf), energy (MMBtu), type of natural gas, biomethane or hydrogen
and associated emissions for all gas imported, sold, produced or distributed
for use in the state for the previous year, and:
(a) If the regulated entity has developed
reporter-specific emission factors or high heating values, then report the
following:
(A) Information used to develop the
reporter-specific emission factor(s) and/or higher heating value(s);
(B) The developed emission factor(s);
and
(C) The developed higher
heating value(s);
(b) For
the purposes of this section large natural gas end users are end users
receiving greater than or equal to 460,000 Mscf of natural gas during the
year;
(c) Report biomethane
contractually delivered to Oregon as specified under OAR 340-215-0044(5);
and
(d) Natural gas suppliers
contractually delivering hydrogen to end users in Oregon must also report
information as specified under OAR 340-215-0044(5);
(2) For local distribution companies,
calculate and report greenhouse gas emissions using quantification
methodologies and report data and information described in 40 C.F.R part 98
subpart NN for suppliers of natural gas and natural gas liquids, as applicable,
unless otherwise specified in this rule including the following:
(a) In addition to submitting all information
needed to meet the requirements of
40 C.F.R.
98.406(b)(1) through (b)(7),
report the annual MMBtu of natural gas associated with the volumes
reported;
(b) Report the amount of
natural gas delivered to each large natural gas end user separately in the
state including customer information required in
40 C.F.R.
98.406(b)(12), and source
identification number if available; and
(c) Report identifying information for each
natural gas marketer contracting use of the distribution system during the year
including company name and address;
(3) For interstate pipeline owners and
operators, report the total amount of natural gas delivered to end users in the
state for use in the state, excluding gas delivered to an Oregon local
distribution company, and:
(a) Report the
annual amount of natural gas delivered to each large natural gas end user
separately in the state including customer information required in
40 C.F.R.
98.406(b)(12), and source
identification number(s) if available. In instances where multiple end users
are downstream of a delivery point that registers at least 460,000 Mscf
annually report the total gas delivered and identifying information for each
user downstream of the delivery point; and
(b) Report identifying information for each
natural gas marketer contracting use of the distribution system during the year
including company name, and address;
(4) Importers of natural gas, by any means
other than a pipeline distribution system or interstate pipeline, and in-state
producers of natural gas or biomethane must separately report:
(a) The total amount of natural gas,
compressed natural gas, liquefied natural gas and biomethane imported or
produced and delivered or sold for use in the state, excluding volumes
delivered to an Oregon local distribution company or injected into an
interstate pipeline; and
(b) The
total amount of natural gas, compressed natural gas, liquefied natural, or
biomethane delivered to each large natural gas end user in the state including
customer information required in
40 C.F.R.
98.406(b)(12), and source
identification number if available; and
(5) For all natural gas suppliers, calculate
and report the CO2, biogenic CO2 from any reported biomass-derived fuel, CH4,
N2O, and CO2e emissions in metric tons that would result from the complete
combustion or oxidation of the annual quantity of natural gas imported, sold,
or distributed for use in this state. Calculate and report greenhouse gas
emissions for the previous year utilizing emission quantification methodology
prescribed in 40 C.F.R. part 98 and as follows:
(a) Calculate greenhouse gas emissions
separately for natural gas, compressed natural gas liquefied natural gas and
biomethane;
(b) Calculate and
report CO2 emissions as follows:
(A) Local
distribution companies must utilize quantification methodologies and report all
data elements as required by 40 C.F.R. 98 subpart NN -
Suppliers of Natural Gas and Natural Gas liquids for the total volume of gas
supplied in the state; and
(B) All
other natural gas suppliers including interstate pipeline owners or operators,
importers of natural gas, in-state producers must calculate and report using
calculation methodology 1 as specified in
40 C.F.R.
98.403(a)(1);
(c) Calculate and report CH4 and N2O
emissions from natural gas imported, sold, or distributed for use in this state
using equation C-8 and table C-2 as required in
40 C.F.R.
98.33(c)(1) for all fuels
subject to reporting;
(d) CO2
emissions from biomass-derived fuel are based on the fuel the natural gas
supplier contractually delivered. Emissions from biomethane are calculated
using the methods for natural gas required by this section, including the use
of the emission factor for natural gas in
40 C.F.R.
98.408, table NN-1. Natural gas suppliers who
report emissions from biomethane must report information required by OAR
340-215-0044(5) and retain supporting documentation as required under OAR
340-215-0042; and
(e) Not report
data or emissions for exported products.
