Definitions

Qualified carbon oxide. This is (a) any carbon dioxide
captured from an industrial source by equipment originally
Instructions for Form 8933 (Rev. 12-2024)

placed in service before February 9, 2018, which would
otherwise be released into the atmosphere as industrial
emission of greenhouse gas or lead to such release, and
is measured at the source of capture and verified at the
point of disposal, injection, or utilization; (b) any carbon
dioxide or other carbon oxide that’s captured from an
industrial source by equipment originally placed in service
on or after February 9, 2018, which would otherwise be
released into the atmosphere as industrial emission of
greenhouse gas or lead to such release, and is measured
at the source of capture and verified at the point of
disposal, injection, or utilization; or (c) in the case of a
DAC facility, any carbon dioxide that’s captured directly
from the ambient air, and is measured at the source of
capture and verified at the point of disposal, injection, or
utilization.
Qualified carbon oxide includes the initial deposit of
captured carbon oxide used as a tertiary injectant. It
doesn’t include carbon oxide that’s recaptured, recycled,
and re-injected as part of the EOR and natural gas
recovery process.
Carbon capture equipment. This includes all
components of property that are used to capture or
process carbon oxide until the carbon oxide is transported
for disposal, injection, or utilization. Carbon capture
equipment is equipment used for the purpose of (1)
separating, purifying, drying, and/or capturing carbon
oxide that would otherwise be released into the
atmosphere from an industrial facility; (2) removing carbon
oxide from the atmosphere via DAC; or (3) compressing or
otherwise increasing the pressure of carbon oxide.
All components that make up an independently
functioning process train capable of capturing,
processing, and preparing carbon oxide for transport will
be treated as a single unit of equipment (single process
train). See Rev. Rul. 2021-13, 2021-30 I.R.B. 152,
available at IRS.gov/irb/2021-30_IRB#REV-RUL-2021-13.

begins, is not yet placed in service; or (ii) was placed in
service during the 1-year period prior to the date on which
construction of the equipment begins, the designed
annual carbon oxide production, by mass, as determined
based on an assumed capacity factor of 60%.
Capacity factor. Capacity factor means the ratio
(expressed as a percentage) of the actual electric output
from the applicable electric generating unit to the potential
electric output from such unit.
Industrial facility. An industrial facility is a facility that
produces a carbon oxide stream from a fuel combustion
source or fuel cell, a manufacturing process, or a fugitive
carbon oxide emission source that, absent capture and
disposal, would otherwise be released into the
atmosphere as industrial emission of greenhouse gas or
lead to such release. An industrial facility doesn’t include a
facility that produces carbon dioxide from carbon dioxide
production wells at natural carbon dioxide-bearing
formations or a naturally occurring subsurface spring.
Depending on your election to use the June 2020 Notice
of Proposed Rulemaking (NPRM) or the TD, see section
3.02(b) of Notice 2009-83 or Regulations section
1.45Q-2(d)(1) and (d)(2).
An Industrial Source is an emission of carbon oxide
from an industrial facility.
A Manufacturing Process is a process involving the
manufacture of products, other than carbon oxide, that are
intended to be sold at a profit, or are used for a
commercial purpose. All facts and circumstances for the
process and products are to be taken into account.

3. In the case of any other facility, captures not less
than 12,500 metric tons of qualified carbon oxide during
the tax year.
Qualified EOR or natural gas recovery project. An
EOR or natural gas recovery project means any project
located in the United States involving the application of
one or more tertiary recovery methods defined in section
193(b)(3) that can reasonably be expected to result in
more than an insignificant increase in the amount of crude
oil or natural gas that will ultimately be recovered and for
which the first injection of liquids, gases, or other matter
begins after 1990.
Natural gas. Natural gas means any product (other than
crude oil) of an oil or gas well if a deduction for depletion is
allowable under section 611 for such product.

service before February 9, 2018, and for which no
taxpayer claimed a section 45Q credit for any tax year
ending before February 9, 2018) that captures not less
than 500,000 metric tons of qualified carbon oxide during
the tax year, you can elect to have the facility, and any
equipment placed in service at the facility, treated as
placed in service on February 9, 2018.
You can make a section 45Q(f)(6) election by filing a
statement of election with your income tax return for each
tax year in which the credit arises. In addition to any
information required on Form 8933, your statement of
Instructions for Form 8933 (Rev. 12-2024)

election must show your name, address, taxpayer
identification number, location, and the identification
number(s) assigned to the facility by the EPA's electronic
Greenhouse Gas Reporting Tool (e-GGRT ID number(s))
(if available).
Note. EPA e-GGRT ID number(s) are identification
number(s) assigned to the facility by the EPA's electronic
Greenhouse Gas Reporting Tool.

Section 45Q(f)(3)(B) Election

In the case of qualified carbon oxide captured using
equipment that’s originally placed in service at a facility
before February 9, 2018, if you’re the person that captures
and physically or contractually ensures the disposal,
injection, or utilization of the qualified carbon oxide, the
credit is attributable to you. You may claim the credit, or
you may elect to allow the credit to the person that
disposes of, injects, or utilizes the qualified carbon oxide.
If you make this election, the amount you elect to allow
won’t be allowed to you. You can also elect to allow only
part of the credit to the person that disposes of, injects, or
utilizes the qualified carbon oxide in a tax year, and to
claim the remainder yourself.
In the case of qualified carbon oxide captured using
equipment that’s originally placed in service at a facility on
or after February 9, 2018, if you’re the person that owns
the equipment and physically or contractually ensures the
capture and disposal, utilization, or use as a tertiary
injectant of such carbon oxide, you may check the box to
elect to allow the credit to another person that disposes of,
injects, or utilizes the qualified carbon oxide. If you make
this election, the amount you elect to allow won’t be
allowed to you. You can also elect to allow only part of the
credit to the person that disposes of, injects, or utilizes the
qualified carbon oxide in a tax year, and to claim the
remainder yourself.
A new section 45Q(f)(3)(B) election must be made
annually. You make a section 45Q(f)(3)(B) election by
filing a Schedule E (Form 8933), no later than the time
prescribed by law (including extensions) for filing your
federal income tax return or Form 1065, U.S. Return of
Partnership Income, for the year in which the credit arises.
You must make a separate election for each facility.
The election may not be filed with an amended
federal income tax return, an amended Form
CAUTION 1065, or an Administrative Adjustment Request
(AAR), as applicable, after the prescribed date (including
extensions) for filing the original federal income tax return
or Form 1065 for the year, with the exception of amended
federal income tax returns, amended Forms 1065, or
AARs, as applicable, for any tax year ending after
February 9, 2018, and beginning on or before January 13,
2021. The amended federal income tax return or the

that during the period beginning after October 3, 2008, a
total of 75,000,000 metric tons of qualified carbon oxide
have been taken into account in accordance with section
45Q(a), as in effect on the day before February 9, 2018,
and section 45Q(a)(1) and (2). See section 45Q(g) as
amended by IRA22 and Notice 2022-38.

When Construction Begins

Two methods can be used to establish that construction of
a facility or equipment has begun.
1. Physical Work Test is satisfied when physical work
of a significant nature begins and other requirements
provided in Section 5 of Notice 2020-12, 2020-11 I.R.B.
495, available at IRS.gov/irb/2020-11_IRB#NOT-2020-12,
are met.
2. Five Percent Safe Harbor is satisfied when you
pay or incur (within the meaning of Regulations section
1.461-1(a)(1) and (2)) 5% or more of the total cost of a
facility or equipment and meets other requirements
provided in Notice 2020-12, Section 6.
Although both methods can be used, only one method
is needed to establish that construction of a facility or
equipment has begun. If you began construction on a
facility or equipment by satisfying either the Physical Work
Test or the Five Percent Safe Harbor, or both, before the
effective date of Notice 2020-12 (March 9, 2020), you may
use March 9, 2020, as the date that construction began on
such facility or equipment. Additionally, if you began
construction on a facility or equipment before March 9,
2020, under both the Physical Work Test and the Five
Percent Safe Harbor, you may choose either method (but
not both) for the purpose of applying the beginning of
construction rules. If you began construction on a facility
or equipment on or after March 9, 2020, construction will
be deemed to have begun on the date you first satisfy
either the Physical Work Test or the Five Percent Safe
Harbor. If you fail to satisfy the Five Percent Safe Harbor in
1 year due to cost overruns (as defined in Section 6.03 of
Notice 2020-12), you won’t be prevented from using the
Physical Work Test in a later year to establish beginning of
construction, provided that occurs before January 1, 2033.

Increased Credit Amount for Facilities
and Equipment

Notice 2022-61 explains how claimants, including
taxpayers, tax-exempt and government entities, and
non-taxable pass-through entities, receive increased
credit amount for any facility or equipment placed in
service after 2022, by satisfying certain requirements. In
the case of any facility or equipment installed in any
facility, the amount of the credit rates as adjusted for
inflation or applicable dollar amounts are multiplied by 5 if
any one of the following requirements are met.
• A facility the construction of which began prior to
January 29, 2023;
• Carbon equipment the construction of which began
prior to January 29, 2023, and installed in a facility; or
• A facility or equipment that satisfies the prevailing wage
and apprenticeship requirements.

Additional information. If you answered “Yes” on Part I,
line 33, and claimed an increased credit amount on Part
III, line 1i, 2i, or 3i, you must attach a statement to Form
8933 that includes the following information.
1. Your name and taxpayer identification number and
the facility or equipment description and IRS-issued
registration number (if applicable) from Part I.
2. If construction began before January 29, 2023, as
shown on Part I, line 5, a statement that you met the
Continuity Requirement under the Physical Work Test or
the Five Percent Safe Harbor to establish the beginning of
construction (alteration or repairs).
3. If construction began on or after January 29, 2023,
include the following.
a. The applicable wage determinations (as defined
later).
b. The wages paid (including any correction payments
as defined in section 45(b)(7)(B)(i)(I)) and hours worked
for each of the laborer or mechanic classifications
engaged in the construction (alteration or repairs) of the
facility or equipment.
c. The number of workers who received correction
payments.
d. The wages paid and hours worked by qualified
apprentices for each of the laborer or mechanic
classifications engaged in the construction (alteration or
repairs) of the facility or equipment.
e. The total labor hours for the construction (alteration
or repairs) of the facility or equipment installed at a facility
by any laborer or mechanic employed by the taxpayer or
any contractor or subcontractor.
4. A declaration, applicable to the statement and any
accompanying documents, signed by you, or signed by a
person currently authorized to bind you in such matters, in
the following form: “Under penalties of perjury, I declare
that I have examined this statement, including
accompanying documents, and to the best of my
knowledge and belief, the facts presented in support of
this statement are true, correct, and complete.”
Applicable wage determinations mean the wage
listed for a particular classification of laborer or mechanic
on the applicable wage determination for the type of
construction and the geographic area or other applicable
Instructions for Form 8933 (Rev. 12-2024)

wage as determined by the Secretary of Labor. See
Notice 2022-61 for more information.

Prevailing Wage Requirements

For any facility and any equipment placed in service at
such facility, you must ensure that any laborers and
mechanics employed by you or any contractor or
subcontractor in (i) the construction of such facility or
equipment, and (ii) for any tax year, for any portion of such
tax year that’s within the period described in section
45Q(a)(3)(A) or (4)(A), the alteration or repair of such
facility or such equipment, must be paid wages at rates
not less than the prevailing rates for construction,
alteration, or repair of a similar character in the locality in
which such facility and equipment are located as most
recently determined by the Secretary of Labor, in
accordance with subchapter IV of chapter 31 of title 40,
United States Code. See Notice 2022-61 for details.
For information on how to correct a failure to satisfy the
prevailing wage requirements, and the penalty related to
the failure, see section 45(b)(7)(B), Notice 2022-61, and
the Instructions for Form 4255, Certain Credit Recapture,
Excessive Payments, and Penalties.

Apprenticeship Requirements

To meet the apprenticeship requirements, you must
ensure that, for the construction of any qualified facility,
not less than the applicable percentage of the total labor
hours of the construction, alteration, or repair work
(including such work performed by any contractor or
subcontractor) for such facility is, subject to section 45(b)
(8)(B), performed by qualified apprentices (apprenticeship
labor hour requirements). The apprenticeship
requirements include three components: a labor-hours
requirement, a ratio requirement, and a participation
requirement.
• You must ensure that 15% of the total labor-hours
performed in the construction, alteration, or repair of the
facility are performed by qualified apprentices from a
registered apprenticeship program.
• You must ensure that the applicable ratio of apprentices
to journeyworkers established by the registered
apprenticeship program are met for apprentices working
on the facility each day.
• Any taxpayer (or contractor or subcontractor) that
employs four or more laborers or mechanics in the
construction, alteration, or repair of the facility must also
hire at least one qualified apprentice.
For information on the penalty related to the failure to
satisfy the apprenticeship requirements, see section 45(b)
(8)(D) and the Instructions for Form 4255.
Beginning of construction. See Sections 2 and 5 of
Notice 2022-61 and When Construction Begins, earlier, to
establish whether construction of a facility or equipment at
a facility began before January 29, 2023.

Recapture

A recapture event occurs when qualified carbon oxide for
which a credit has been claimed ceases to be captured,
disposed of, or used as a tertiary injectant during the
recapture period. Recapture events are determined
separately for each project involving capture, disposal, or
use of qualified carbon oxide as a tertiary injectant.

The type and rule above prints on all proofs including departmental reproduction proofs. MUST be removed before printing.

Qualified carbon oxide ceases to be captured,
disposed of, or used as a tertiary injectant if the leaked
amount of qualified carbon oxide in the tax year exceeds
the amount of qualified carbon oxide disposed of in
secure geological storage or used as a tertiary injectant in
that same tax year.
If a recapture event occurs during a project’s recapture
period and you have claimed a credit for that project, you
must report the following information on a Schedule D
(Form 8933), Recapture Certification, filed with your
federal income tax return or Form 1065 for the tax year for
which the recapture event occurred.
• The recapture amount (as defined in Regulations
section 1.45Q-5(e));
• The quantity of leaked qualified carbon oxide (in metric
tons) (as defined in Regulations section 1.45Q-5(c));
• The statutory credit rate at which the credits were
originally calculated; and
• A statement that describes how you became aware of
the recapture event, how the leaked amount was
determined, and the identity and involvement of any
regulatory agencies.

Credit Reduced for Tax-Exempt Bond
Financing

For facilities or equipment placed in service after 2022,
the credit is reduced by an amount that is the product of
the credit amount otherwise determined for the tax year
and the lesser of 15% or a fraction determined for the tax
year. The numerator of the fraction is the sum, for the tax
year and all prior tax years, of the proceeds from an issue
of any obligations the interest on which is exempt from tax
under section 103 and that is used to provide financing for
the facility as of the close of the tax year. The denominator
of the fraction is the aggregate amount of additions to the
capital account for the facility for the tax year and all prior
tax years as of the close of the tax year.

Coordination With Section 142 Bond
Financing

For facilities or equipment placed in service before 2023
and obligations issued after 2021, the credit for any
project for any tax year is reduced by the amount that's the
product of the credit for such tax year and the lesser of
50% or a fraction, the numerator of which is the sum, for
the tax year and all prior tax years, of the proceeds from
an issue described in section 142(a)(17) used to provide
financing for the project the interest on which is exempt
from tax under section 103, and the denominator of which
is the aggregate amount of additions to the capital
account for the project for the tax year and all prior tax
years. The amounts under the preceding sentence for any
tax year are determined as of the close of the tax year.
Note. For purposes of the above, there are no prior tax
years before January 1, 2022.

Reporting Requirements
General Requirements

If you’re claiming the credit, you must provide the name
and location of the facilities at which the qualified carbon
oxide was captured.

8

If you’re claiming the credit on an amended federal
income tax return, an amended Form 1065, or an
CAUTION AAR, as applicable, you must state “AMENDED
RETURN FOR SECTION 45Q CREDIT” at the top of your
amended federal income tax return, amended Form 1065,
or AAR, as applicable. Your amended federal income tax
return or the amended Form 1065 must be filed, in no
event, later than the applicable period of limitations on
assessment for the tax year for which your amended
federal income tax return or Form 1065 is being filed.

Contractually Ensuring Disposal, Injection, or
Utilization of Qualified Carbon Oxide

If you enter into a contract with another party to ensure
disposal, injection, or utilization of qualified carbon oxide,
you must report the existence of each contract, and the
parties involved annually on Form 8933 by each party to
the contract, regardless of the party claiming the credit. In
addition to any information stated as required on Form
8933 and the applicable Schedules A through F (Form
8933), the report must include the following information.
• Your name and identifying number;
• The name and taxpayer identification number of each
party with whom you have entered into a contract to
ensure the disposal, injection, or utilization of qualified
carbon oxide;
• The date on which each contract was executed;
• The number of metric tons of qualified carbon oxide
each contracting party disposes of, injects, or utilizes on
behalf of you each tax year for reporting to the IRS; and
• For contracts for the disposal of qualified carbon oxide
in secure geological storage or the use of qualified carbon
oxide as a tertiary injectant in EOR or natural gas
recovery, identifying information (the name of the operator,
field, unit, and reservoir), location by county and state,
and EPA e-GGRT ID number(s) (if available) for
submission of the facility’s 40 CFR Part 98 (subpart RR)
annual reports.

Secure Geological Storage

Certifications must be made annually.

Reporting Based on 40 CFR Part 98 (Subpart RR)
For an EOR or natural gas recovery project in which you
reported volumes to the EPA pursuant to 40 CFR Part 98
subpart RR, you may self-certify the volume of carbon
oxide claimed for purposes of the credit.

Reporting Based on CSA/ANSI ISO 27916:19
For an EOR or natural gas recovery project in which you
determined volumes pursuant to CSA/ANSI ISO
27916:19, you may prepare documentation as outlined in
CSA/ANSI ISO 27916:19 internally, but such
documentation must be provided to a qualified
independent engineer or geologist, who then must certify
that the documentation provided, including the mass
balance calculations as well as information regarding
monitoring and containment assurance, is accurate and
complete. For any leaked amount of qualified carbon
oxide that’s determined pursuant to CSA/ANSI ISO
27916:19, the certification must also include a statement

that the quantity was determined in accordance with
sound engineering principles.
If you capture qualified carbon oxide to get the credit,
you must file Form 8933 with your timely filed federal
income tax return or Form 1065, including extensions, or
for the purpose of this rule, your amendments to federal
income tax returns, Forms 1065, or on AARs, as
applicable. Similarly, if you dispose of, inject, or utilize
qualified carbon oxide, you must also file Form 8933 with
your timely filed federal income tax return or Form 1065,
including extensions, or for the purpose of this rule, your
amendments to federal income tax returns, Forms 1065,
or on AARs, as applicable. If the volume of carbon oxide
certified and reported is a negative amount, see
Regulations section 1.45Q-5 for rules regarding recapture.
No credit is allowed for any tax year for which you
(including credit claimants) have failed to timely
CAUTION submit complete documentation, including the
required certifications. The credit will be allowed only for a
tax year for which complete documentation and
certification has been timely submitted. Certifications for
each tax year must be submitted by the due date of your
federal income tax return or Form 1065 on which the credit
is claimed, including extensions. If your credit is claimed
on your amended federal income tax return, amended
Form 1065, or AAR, as applicable, certifications may also
be submitted with your amended federal income tax
return, amended Form 1065, or AAR. If a credit was
claimed on your timely filed federal income tax return or
Form 1065 for a tax year ending after February 9, 2018,
and beginning on or before January 13, 2021, for which
certifications weren’t submitted, such certifications may be
submitted with your amended federal income tax return,
amended Form 1065, or AAR, as applicable, for the tax
year in which the credit was claimed.

tax year in which injection activity ceases and all injection
wells are plugged and abandoned.

Utilization

The amount of qualified carbon oxide utilized by you is
equal to the metric tons of qualified carbon oxide that you
demonstrate, based upon the LCA, that were captured
and permanently isolated from the atmosphere (isolated),
or displaced from being emitted into the atmosphere
(displaced).
Lifecycle greenhouse gas emissions and lifecycle
analysis. The term “lifecycle greenhouse gas emissions”
means the aggregate quantity of greenhouse gas
emissions (including direct emissions and significant
indirect emissions such as significant emissions from land
use changes) related to the full product lifecycle, including
all stages of product and feedstock production and
distribution, from feedstock generation or extraction
through the distribution and delivery and use of the
finished product to the ultimate consumer, where the
mass values for all greenhouse gases are adjusted to
account for their relative global warming potential
according to Table A-1 of 40 CFR Part 98 subpart A. The
amount of lifecycle greenhouse gas emissions measured
by a LCA is expressed in carbon dioxide equivalents
(CO2-e).
Measurement. The measurement and written LCA report
must be performed by or verified by an independent third
party. The LCA report must be prepared in conformance
with, and contain documentation that conforms to, the
International Organization for Standardization (ISO)
14040:2006, Environmental Management—Life Cycle
Assessment—Principles and Framework, and ISO
14044:2006, Environmental Management—Life Cycle
Assessment—Requirements and Guidelines, as well as a
statement documenting the qualifications of the
independent third party, including proof of appropriate
U.S. or foreign professional license, and an affidavit from
the third party stating that it's independent from you.

Specific Instructions
To claim the credit for disposal of carbon oxide in secure
geological storage or for use of carbon oxide as a tertiary
injectant in an EOR or natural gas recovery project, prior
to disposal in secure geological sequestration, the amount
of carbon oxide must be measured at the source of
capture and verified either at the point of disposal in
secure geological storage or at the point of injection as a
tertiary injectant in an EOR or natural gas recovery
project. The amount of qualified carbon oxide is presumed
to be the lesser of the amount measured at capture and
the amount verified at disposal or injection unless it can
be established to the satisfaction of the IRS that the
greater amount is the correct amount.
To claim the credit for utilization of carbon oxide, the
amount of qualified carbon oxide utilized by you is equal to
the metric tons of qualified carbon oxide that you
demonstrate, based upon the LCA, were (1) captured and
permanently isolated from the atmosphere, or (2)
displaced from being emitted into the atmosphere. The
amount of qualified carbon oxide utilized by you for
purposes of the credit can't exceed the amount of
qualified carbon oxide measured at the source of capture.

Instructions for Schedules A
Through F (Form 8933)

Per the TD and the NPRM that preceded it, if you’re a
large section 45Q project filer, you’ll likely have to use
multiple legal contracts with multiple parties for the
capture, utilization, or disposal of carbon oxides and,
generally to claim the credit, the existence of each
contract and the parties involved must be reported on
Form 8933 annually. For this reporting, filers should also
use the applicable Schedules A, B, C, D, E, and F shown
below.
Disposal or Enhanced Oil Recovery Owner Certification. Use Schedule A (Form 8933) if you’re the owner (or
one of the owners) of the geological disposal site or the
EOR project at which captured qualified carbon oxide was

injected during the year. The operator of the disposal site
prepares Schedule B (Form 8933). The operator of the
EOR project prepares Schedule C (Form 8933). Report
the amounts from either Schedule B (Form 8933), line 10,
or Schedule C (Form 8933), line 20, on the applicable
lines of Schedule A (Form 8933).
Disposal Operator Certification. Use Schedule B
(Form 8933) if you’re the operator (or designated operator)
of a geological disposal site at which captured qualified
carbon oxide was injected during the year. Don’t use this
schedule if carbon oxide was injected for enhanced oil or
natural gas recovery. Provide a copy of your Schedule B
(Form 8933) to each owner of the disposal site project.
Enhanced Oil Recovery Operator Certification. Use
Schedule C (Form 8933) if you’re the operator (or
designated operator) of an enhanced oil or gas recovery
project (EOR project) at which captured qualified carbon
oxide was injected during the year. Provide a copy of your
Schedule C (Form 8933) to each owner of the EOR
project.
Recapture Certification. Use Schedule D (Form 8933) if
you’re the operator or owner of the geological disposal site
or EOR project to report a recapture event. After you
figured the recapture amount using Schedule D (Form
8933), enter the amount on Form 8933, Part III, line 7; and
in Form 4255, Part I, line 2a, column (h). Complete Form
4255, Certain Credit Recapture, Excessive Payments, and
Penalties, to determine the amount from Form 4255 that
will be reported on your tax return. See the Instructions for
Form 4255 for details.
Election Certification. Use Schedule E (Form 8933) if
(1) you’re the owner of the capture facility that supplied
qualified carbon oxide to another person that was properly
disposed of in geological storage, used in an EOR project,
or utilized in a manner consistent with section 45Q(f), and
(2) you elect under section 45Q(f)(3)(B) to allow the credit
to that person. You must make a separate election for
each facility.
Utilization Certification. Use Schedule F (Form 8933) if
you’re the owner of the utilization facility who utilized
qualified carbon oxide during the year. Don’t combine
information from separate utilization facilities on the same
schedule. Provide a copy of your Schedule F (Form 8933)
to each supplier that supplied qualified captured carbon
oxide to inform the suppliers of the amount of their
qualified carbon oxide that was utilized.
