SECTION 1
INTRODUCTION AND BACKGROUND
1.1	Greenhouse Gas Reporting Program Background
The Greenhouse Gas (GHG) Reporting Program requires reporting of GHG emissions
and other relevant information from certain source categories in the United States. The GHG
Reporting Program does not require the control of GHGs; rather it requires only monitoring and
reporting of GHGs. 40 CFR part 98 provides the regulatory framework for the GHG Reporting
Program. The GHG Reporting Program, which became effective on December 29, 2009,
includes reporting requirements for facilities and suppliers in 34 subparts. For more detailed
background information on the GHG Reporting Program, see the preamble to the final Part 98
rule establishing that program (74 FR 56260, October 30, 2009) and the preamble to the Part 98
rule expanding that program from 30 to 34 subparts (75 FR 39736, July 12, 2010).
1.2	Monitoring and Reporting Requirements for Injection and Geologic Sequestration
of Carbon Dioxide: Subpart RR and UU
On April 12, 2010, EPA proposed this rule, amending the Greenhouse Gas (GHG)
Reporting Program at 40 CFR part 98. Subpart PP of the GHG Reporting Program requires the
reporting of carbon dioxide (CO2) supplied to the economy. During the public comment period
on the Part 98 rule establishing that requirement, EPA received many comments that CO2
geologically sequestered should be considered in the GHG Reporting Program. (For further
information on relevant comments received in 40 CFR part 98, subpart PP, see "Mandatory
Greenhouse Gas Reporting Rule: EPA's Response to Public Comments, Subpart PP: Suppliers
of Carbon Dioxide" at EPA-HQ-OAR-2008-0508.) In the final rule promulgating 40 CFR part
98, subpart PP, EPA committed to taking action to collect such data in the near future.
This final rule amends 40 CFR part 98 to add reporting requirements covering facilities
that conduct geologic sequestration of CO2 (40 CFR part 98, subpart RR) and all other facilities
that conduct injection of CO2 (40 CFR part 98, subpart UU).1 GS is the long-term containment
of a CO2 stream in subsurface geologic formations. This data will, among other things, inform
Agency decisions under the CAA related to the use of carbon dioxide capture and geologic
sequestration (CCS) for mitigating GHG emissions.
1 EPA has moved all definitions, requirements, and procedures for facilities conducting C02 injection only (which
both EPA and commenters have referred to as "Tier 1 " facilities for simplicity) into a new subpart, 40 CFR part
98, subpart UU, and retained all definitions, requirements, and procedures related to facilities conducting GS
(which both EPA and commenters have referred to as "Tier 2" facilities for simplicity) in 40 CFR part 98,
subpart RR.
1-1

-------
Subpart RR information will enable EPA to monitor the growth and efficacy of GS (and
therefore CCS) as a GHG mitigation technology over time and to evaluate relevant policy
options. Furthermore, where enhanced oil and gas recovery (ER) projects are reporting under 40
CFR part 98, subpart RR, EPA will be able to evaluate ER as a non-emissive end use. Under 40
CFR part 98, subpart UU, EPA will be able to reconcile information obtained from this rule with
data obtained from 40 CFR part 98, subpart PP on CO2 supplied to the economy.
The rule was proposed by EPA on April 12, 2010. One public hearing was held on April
19, 2010, and the 60-day public comment period ended June 11, 2010. This final rule takes into
consideration comments received during the comment period and finalizes the monitoring and
reporting requirements for facilities conducting GS and all other facilities conducting CO2
injection.
This final rule does not address whether data reported under 40 CFR part 98, subparts RR
or UU will be released to the public or will be treated as CBI. EPA published a proposed rule on
confidentiality determination on July 7, 2010 (75 FR 39094) that addressed this issue. In that
action, EPA proposed which specific data elements may be released to the public and which
would be treated as CBI. EPA received several comments on that proposal under that action, and
is in the process of considering these comments.

SECTION 2
REGULATORY BACKGROUND
The intent of the GHG Reporting Program is to collect accurate and timely GHG data
that can be used to inform future policies. Although the GHG Reporting Program is unique, EPA
carefully considered other federal and state programs during development of the rule. The
reporting program will supplement rather than duplicate other U.S. government GHG programs.
We outline EPA's overall rulemaking approach, statutory authority, relationship to and
coordination with the Safe Drinking Water Act Underground Injection Control Class VI rule, and
summarize the relationship to the Interagency Task Force on Carbon Capture and Storage and
other Federal GS initiatives, as well as the relationship to other geologic sequestration
information collection and reporting efforts below.
2.1 EPA's Overall Rulemaking Approach
The GHG Reporting Program provides comprehensive and accurate data which will
inform future climate change policies. Potential future climate policies include research and
development initiatives, economic incentives, new or expanded voluntary programs, adaptation
strategies, emission standards, a carbon tax, or a cap-and-trade program. Because we do not
know at this time the specific policies that will be adopted, the data reported to the GHG
Reporting Program should be of sufficient quality to support a range of approaches.
To these ends, we identified the following goals of the GHG Reporting Program:
Obtain data that is of sufficient quality that it can be used to support a range of
future climate change policies and regulations.
Balance the rule coverage to maximize the amount of emissions reported while
excluding small emitters.
Create reporting requirements that are consistent with existing GHG reporting
programs by using existing GHG emission estimation and reporting
methodologies to reduce reporting burden, where feasible.
This section presents the current regulatory context for Subparts RR and UU and
illustrates the anticipated role of the final rule within the framework of the existing mandatory
and voluntary programs.

-------
2.2	Statutory Authority
EPA is promulgating this rule under its existing CAA authority; specifically, authorities
provided in CAA section 114. As discussed in detail in Sections I.C and II. Q of the preamble to
the Part 98 rule establishing the GHG Reporting Program (74 FR 56260, October 30, 2009),
CAA section 114 provides EPA with broad authority to require information mandated by this
rule, because such data will inform and are relevant to EPA's carrying out a wide variety of CAA
provisions. Under CAA section 114(a)(1), the Administrator may require emissions sources,
persons subject to the CAA, manufacturers of emission control or process equipment, or persons
whom the Administrator believes may have necessary information to monitor and report
emissions and provide such other information as the Administrator requests for the purposes of
carrying out any provision of the CAA (except for a provision of title II with respect to motor
vehicles). EPA may gather information for a variety of purposes, including for the purpose of
assisting in the development of implementation plans or of emissions standards under CAA
section 111, determining compliance with implementation plans or such standards, or more
broadly for "carrying out any provision" of the CAA.
2.3	Safe Drinking Water Act and UIC Regulations
The Agency maintains a high-level of coordination across EPA offices and regions on GS
activities and regulatory development. EPA's Office of Air and Radiation (OAR) and Office of
Water (OW) work closely to promote safe and effective implementation of GS technologies
while ensuring protection of human health and the environment. OAR and OW have closely
coordinated this rulemaking under CAA authority and the rulemaking under Safe Drinking
Water Act (SDWA) authority establishing Federal requirements under the UIC program for
Class VI wells.
EPA's UIC program was established in the 1970s to prevent endangerment of
underground sources of drinking water (USDWs) from injection of various fluids, including CO2
for ER, oil field fluids, water stored for drinking water supplies, and municipal and industrial
waste. The UIC program, which is authorized by Part C of SDWA (42 U.S.C. 300h et seq.), is
designed to prevent the movement of such fluid into USDWs by addressing the potential
pathways through which injected fluids can migrate and potentially endanger USDWs. In 2008,
EPA proposed to amend the UIC program to establish a new class of injection well — Class VI
— to cover the underground injection of CO2 for the purpose of GS, or long-term storage of CO2
(73 FR 43492, July 25, 2008). For a summary of the UIC program and more details on the final
UIC Class VI rule, please see the UIC Geologic Sequestration of Carbon Dioxide website:
http://water.epa.gov/type/groundwater/uic/wells_sequestration.cfm.
2-2

-------
EPA designed the reporting requirements under 40 CFR part 98, subpart RR with careful
consideration of UIC requirements, including Class VI, to minimize overlap between the two
programs. There are two areas of potential overlap. The first overlap is the requirement that
owners or operators report the quantity of CO2 injected. The UIC Class VI rule requires owners
or operators to continuously monitor the amount of CO2 injected and submit semi-annual reports
on the monthly amount injected. The UIC program requires information on the amount injected
to ensure appropriate CO2 injection operations. Subpart RR requires facilities to collect data on
the amount injected over a quarter and submit annual reports on the annual amount of CO2
injected. Data on the amount of CO2 injected is a component of the 40 CFR part 98, subpart RR
mass balance approach used to quantify the amount of CO2 sequestered. EPA determined that
quarterly data collection and annual reporting under 40 CFR part 98, subpart RR was necessary
in order to harmonize data with other subparts of the GHG Reporting Program. Facilities
reporting under 40 CFR part 98, subpart RR may use flow meters used to comply with the flow
monitoring and reporting provisions in their permit.
The second overlap is a monitoring plan for detecting air emissions. While requirements
under the UIC program are focused on demonstrating that USDWs are not endangered as a result
of CO2 injection into the subsurface, requirements under the GHG Reporting Program through
40 CFR part 98, subpart RR will enable EPA to verify the quantity of CO2 that is geologically
sequestered and to assess the efficacy of GS as a mitigation strategy. Subpart RR achieves this
by requiring facilities conducting GS to develop and implement a monitoring, reporting, and
verification (MRV) plan1 to detect and quantify leakage of injected CO2 to the surface in the
event leakage occurs and to report the amount of CO2 geologically sequestered using a mass
balance approach, regardless of the class of UIC permit that a facility holds.
The monitoring required by 40 CFR part 98, subpart RR for quantification purposes is
complementary to and builds on UIC permit requirements. In particular, the UIC Class VI
permit requires a comprehensive site characterization that includes an assessment of the
geologic, hydrogeologic, geochemical, and geomechanical properties of the proposed GS site to
ensure that GS wells are located in suitable formations. The UIC Class VI permit also requires
computational modeling of the Area of Review, and a periodic re-evaluation of this Area of
Review based on robust modeling and monitoring of the CO2 stream, injection pressures,
integrity of the injection well, groundwater quality and geochemistry, and the position of the CO2
1 The subpart RR MRV plan includes delineation of monitoring areas, identification and assessment of potential
surface leakage pathways, a strategy for detecting and quantifying surface leakage of C02 if leakage occurs, an
approach for establishing the expected baselines, and a summary of considerations for calculating site-specific
variables for the mass balance equation, such as calculating C02 in produced fluids.

plume and pressure front throughout injection. These requirements can provide the basis for the
MRV plan submitted to EPA for 40 CFR part 98, subpart RR. Therefore, EPA will accept a UIC
Class VI permit to satisfy certain MRV plan requirements; however, the reporter must include
additional information to outline how monitoring will achieve detection and quantification of
CO2 in the event surface leakage occurs.
The UIC Class VI rule also allows for surface air and soil gas monitoring at the discretion
of the Director as a means of identifying CO2 leaks that may pose a risk to USDWs and
informing emergency notification of a UIC Class VI owner or operator and UIC Director in the
event of a USDW endangerment. If the Director determines that it is appropriate to require
surface air or soil gas monitoring for USDW protection, the Director must approve the use of
monitoring employed under 40 CFR part 98, subpart RR so long as the owner or operator is able
to demonstrate USDW protection pursuant to requirements at § 146.90(h)(3).
EPA has determined that the requirements of these two rules complement one another by
concurrently ensuring USDW protection, as required under SDWA, and requiring reporting of
CO2 surface emissions under 40 CFR part 98, subpart RR. EPA is committed to working
closely within the agency to coordinate implementation of the UIC and GHG Reporting
programs, reduce burden on reporters, provide timely access to verified emissions data, establish
mechanisms to efficiently share data, and harmonize data systems to the extent possible.
In the cost analysis conducted for this rule, EPA has assumed that for saline sequestration
projects these requirements are in the baseline, and consequently estimated incremental costs
associated with surface detection and quantification of CO2. Further detail on the cost analysis is
available in sections 4 and 5 of this document. EPA is committed to working closely within the
agency to coordinate implementation of the UIC and GHG Reporting programs, reduce burden
on reporters, provide timely access to verified emissions data, establish mechanisms to
efficiently share data, and harmonize data systems to the extent possible.
2.4 Relationship to the Interagency Task Force on Carbon Capture and Storage and
Other Federal GS Initiatives
On February 3, 2010, President Obama established an Interagency Task Force on Carbon
Capture and Storage (CCS Task Force). The CCS Task Force, co-chaired by EPA and the
Department of Energy (DOE), developed a plan to overcome the barriers to the widespread, cost-
effective deployment of CCS within ten years, with a goal of bringing five to ten commercial
demonstration projects online by 2016. The CCS Task Force's plan was delivered to President
Obama in August 2010.
2-4

-------
The CCS Task Force explored incentives for commercial CCS adoption and addressed
financial, economic, technological, legal, institutional, social, or other barriers to deployment.
For example, the CCS Task Force examined Federal regulatory activities that address the safety,
efficacy, and environmental soundness of GS. The CCS Task Force also considered how best to
coordinate existing administrative authorities and programs, including those involving
international collaboration, as well as identified areas where additional administrative authority
may be necessary. The CCS Task Force recommended that EPA finalize this rule. For more
information, please see the CCS Task Force website:
http://www.epa.gov/climatechange/policy/ccs_task_force.html.
2.5 Relationship to Other Geologic Sequestration Information Collection and Reporting
Efforts
EPA reviewed and took into account several existing domestic and international reporting
and monitoring programs in designing this rule. For additional information, please see Section
I.F of the notice of proposed rulemaking (75 FR 18581, April 12, 2010).
Also as discussed in the notice of proposed rulemaking, EPA notes that the Internal
Revenue Service (IRS) published IRS Notice 2009-83 (available at: http://www.irs.gov/irb/2009-
44_IRB/arl I.html#d0el860) to provide guidance regarding eligibility for the Internal Revenue
Code section 45Q credit for C02 sequestration, computation of the section 45Q tax credit,
reporting requirements for taxpayers claiming the section 45Q tax credit, and rules regarding
adequate security measures for secure GS. As clarified in the IRS guidance, taxpayers claiming
the section 45Q tax credit must follow the appropriate UIC requirements. The guidance also
clarifies that taxpayers claiming section 45Q tax credit must follow the MRV procedures that are
being finalized under 40 CFR part 98, subpart RR in this final rule.

SECTION 3
SUMMARY OF FINAL RULE: SUBPART RR AND UU
Facilities that conduct geologic sequestration are subject to 40 CFR part 98, subpart RR.
All other facilities that inject CO2 underground are subject to 40 CFR part 98, subpart UU. If
you report under 40 CFR part 98, subpart RR for a well or group of wells, you are not required to
report under 40 CFR part 98, subpart UU for that well or group of wells.
3.1 Subpart RR
3.1.1 Source Category Definition
The 40 CFR part 98, subpart RR source category consists of any well or group of wells
that inject a CO2 stream for long-term containment into a subsurface geologic formation.1 All
wells permitted as Class VI by the UIC program meet the definition of this source category.
Facilities conducting ER are not subject to 40 CFR part 98, subpart RR unless they choose to
opt-in to the requirements of this subpart or hold a UIC Class VI permit.
R&D projects are exempt from reporting requirements under 40 CFR part 98, subpart RR
provided they meet the eligibility requirements. A project is eligible for the exemption if it
investigates or will investigate practices, monitoring techniques, or injection verification, or if it
is engaged in other applied research that focuses on enabling safe and effective long-term
containment of a CO2 stream in subsurface geologic formations, including research and injection
tests conducted as a precursor to a larger more permanent long-term storage operation. Small
and large-scale projects meeting the criteria for an exemption, such as the current Regional
Carbon Sequestration Partnership projects supported by the Office of Fossil Energy at the
Department of Energy (DOE), would be considered R&D for the purposes of this exemption
from reporting for the duration of the R&D activity. Other DOE supported GS R&D projects
may also satisfy the eligibility requirements for the exemption. In addition, short duration CO2
injection projects conducted to identify local amenability to long term storage will be exempted
from 40 CFR part 98, subpart RR for the duration of such injection testing. This includes cases
where an operator is using a short duration CO2 injection test to assess local geologic conditions
and validate the injectivity potential of a particular site prior to developing that site for
commercial scale geologic storage of carbon dioxide. Demonstration projects can apply for the
1 Note that R&D projects that are exempted from subpart RR report under Subpart UU - see discussion below.

-------
exemption, but will be measured against the same criteria established in 40 CFR 98.440(d).
Projects that are not R&D projects, such as commercial GS operations, are not eligible for the
exemption.
To receive an R&D exemption, the project representative must submit to the
Administrator information on the planned duration of CO2 injection for research, the planned
annual C02 injection volumes during this time period, the purposes of the project, the source and
type of funding for the project, and the class and duration of UIC permit, or, for an offshore
facility not subject to SDWA, a description of the legal instrument authorizing GS.
The Administrator will determine if a project meets the definition of research and
development project within 60 days of receipt of the submission of a request for exemption. In
making this determination, the Administrator will take into account any information that the
reporter submits demonstrating that the planned duration of CO2 injection for the project and the
planned annual CO2 injection volumes during the duration of the project are consistent with the
purpose of the research and development project. This rule allows for administrative appeals of
the Administrator's R&D determination, as provided for in 40 CFR part 78.
Facilities that qualify for a GS R&D exemption from 40 CFR part 98, subpart RR are not
exempted from any other source category of the GHG Reporting Program including 40 CFR part
98, subpart UU. For other source categories of the GHG Reporting Program, R&D is defined at
40 CFR 98.6.
3.1.2 Subpart RR Reporting Threshold
All facilities that meet the 40 CFR part 98, subpart RR source category definition must report
(i.e., there is no reporting threshold). However, reporters that receive a subpart RR R&D
exemption are no longer subject to subpart RR, but rather report CO2 received under subpart UU.
The cease reporting provisions of §98.2(i) do not apply to subpart RR. Rather, once a facility is
subject to the requirements of this subpart, including facilities that opt-in to 40 CFR part 98,
subpart RR, the owner or operator must continue for each year thereafter to comply with all
requirements of this subpart, including the requirement to submit annual GHG reports, until the
Administrator has issued a final decision on an owner or operator's request to discontinue
reporting. The request to discontinue reporting must include either a copy of the applicable UIC
program Director's authorization of site closure, or a demonstration that the injected CO2 stream
is not expected to migrate in a manner likely to result in surface leakage. Before the reporter can
3-2

-------
discontinue reporting, but after injection has ceased, EPA expects that in most cases there will be
minimal burden in monitoring and reporting unless a surface leak is detected.
3.1.3	Subpart RR GHGs to Report
Facilities covered by this source category must report the mass of CO2 received; the mass
of CO2 injected; the mass of CO2 produced (i.e., mixed with produced oil, gas, or other fluids);
the mass of CO2 emitted from surface leakage; the mass of CO2 equipment leaks and vented CO2
emissions from sources between the injection flow meter and the injection wellhead or between
the production flow meter and the production wellhead; and the mass of CO2 sequestered in
subsurface geologic formations (this is calculated from the other quantities).
3.1.4	Subpart RR GHG Calculations and Monitoring
Facilities covered by this source category must calculate the annual mass of CO2
received. Starting from the date specified in the EPA-approved MRV plan, facilities must also
use a mass balance approach to calculate the mass of CO2 geologically sequestered. First,
facilities must calculate the annual mass of CO2 injected. From the annual mass of CO2 injected,
facilities must subtract the mass of CO2 emitted from surface leakage, using the site-specific
procedures in their MRV plan, and the mass of CO2 emitted as equipment leaks or vented
emissions from applicable surface equipment, using the procedures specified in 40 CFR part 98,
Subpart W of the GHG Reporting Program. All GS projects with equipment leak or vented
emissions from surface equipment applicable to the GS mass balance equation should use the
procedures specified in subpart W, regardless of whether such projects are associated with the oil
and gas industry. Facilities that are producing, oil, gas, or other fluids must additionally subtract
the mass of CO2 produced. Calculation procedures are provided at 40 CFR 98.443.
3.1.5	Subpart RR Data Reporting
In addition to the information summarized at "Subpart RR GHGs to Report" in this
section of the preamble, facilities must report the source of the CO2 received and the cumulative
amount of CO2 geologically sequestered since the facility first reported under subpart RR. All
facilities must also report concentration, facilities using mass flow meters must report mass flow
information, facilities using volumetric flow meters must report volumetric flow information,
and facilities using containers must measure the mass or volume of the containers. They are
required to report a description of the monitoring program that was implemented, including
3-3

-------
descriptions of monitoring anomalies and surface leakage, if any. Finally, for EPA verification
purposes, they are required to report for each injection well the class of UIC permit and well
identification number used for the UIC permit.
Subpart RR requires reporting of CO2 equipment leaks and vented CO2 emissions to the
extent they are a component of the GS mass balance. Subpart RR does not require reporting of
CO2 equipment leaks and vented CO2 emissions from all surface equipment located within the
facility (e.g., operational emissions not related to the CO2 being injected); however, GS projects
that produce oil or natural gas may be required to report CO2 equipment leaks and vented CO2
emissions in the petroleum and natural gas system subpart, 40 CFR part 98, subpart W as part of
either offshore or onshore petroleum and natural gas production.
3.1.6	Subpart RR Recordkeeping
Facilities must retain quarterly records of CO2 received; injected CO2; produced CO2;
CO2 emitted by surface leakage; CO2 emitted as equipment leaks and vented emissions from
equipment located on the surface between the flow meter used to measure the injection quantity
and the injection wellhead and between the flow meter used to measure the production quantity
and the production wellhead; and any other records as outlined for retention in the facility MRV
plan for 3 years per 40 CFR 98.3(g).
3.1.7	Subpart RR Administrative Appeals
Under this final rule, final decisions of the Administrator under part 98, subpart RR are
appealable to EPA's Environmental Appeals Board under the regulations that are set forth in part
78 (40 CFR part 78). Part 78 is revised to accommodate such appeals. Specifically, the list in 40
CFR 78.1 of the types of final decisions that can be appealed under 40 CFR part 78 is expanded
to cover final decisions of the Administrator under 40 CFR part 98, subpart RR. This list
includes, but is not limited to, the following specific types of decisions under subpart RR, e.g..
the determination of eligibility for an R&D exemption under 40 CFR 98.440(d)(4), the approval
or disapproval of a request for discontinuation of reporting under 40 CFR 98.441(b)(2), and the
approval or disapproval of a MRV plan under 40 CFR 98.448(c).
Further, 40 CFR 78.3 is revised to allow for petitions for administrative appeal of
decisions of the Administrator under 40 CFR part 98, subpart RR. Under the general approach in
the existing part 78, an "interested person" (in addition to the official representative of owners
and operators involved in a matter) may petition for an administrative appeal of a final decision
3-4

-------
of the Administrator. The "interested person" definition, which is located in part 72 of the Acid
Rain Program regulations, is expanded to take into account final decisions of the Administrator
under part 98. In particular, EPA is revising the "interested person" definition by replacing
specific references to the Acid Rain Program and draft permits with broader references to any
decision by the Administrator and the Administrator's process of making that decision. As a
result of this revision and the revisions of 40 CFR part 78, a person who does not own or operate
a facility covered by a final decision under 40 CFR part 98, subpart RR will need to submit his or
her name to be included by the Administrator on an "interested persons list" in order to be able to
appeal — by filing a petition for an administrative appeal — that final decision.
In addition, 40 CFR 78.4 is expanded to state that filings on behalf of owners and
operators of a facility subject to 40 CFR part 98, subpart RR must be signed by the designated
representative of the owners and operators.
3.2 Subpart UU
3.2.1	Subpart UU Source Category Definition
The 40 CFR part 98, subpart UU source category consists of any well or group of wells
that inject a CO2 stream into the subsurface. This includes any wells used to enhance oil and gas
recovery and GS R&D projects that are exempted from 40 CFR part 98, subpart RR monitoring
and reporting requirements. If you report under 40 CFR part 98, subpart RR for a well or group
of wells, you are not required to report under 40 CFR part 98, subpart UU for that well or group
of wells.
3.2.2	Subpart UU Reporting Threshold
All facilities that inject CO2 underground must report under this subpart, regardless of the
amount of emissions from the facility or the amount of CO2 injected. Reporters can cease subpart
UU reporting pursuant to the provisions at 40 CFR 98.2(i) that allow facilities to cease GHG
reporting to EPA; with respect to subpart UU, any reference to CO2 emissions in 40 CFR 98.2(i)
means CO2 received.
3.2.3	Subpart UU GHGs to Report
Facilities covered by this source category must report the annual mass of CO2 received.
3.2.4	Subpart UU GHG Calculations and Monitoring
Facilities covered by this source category must calculate the annual mass of CO2 received
using the calculation procedures for either mass or volumetric flow meters. Where CO2 is
3-5

-------
received in containers, facilities must use the calculation procedures for determining the mass or
volume of contents in containers.
3.2.5	Subpart UU Data Reporting
In addition to reporting the mass of CO2 received, facilities must report the source of the
CO2. All facilities must also report concentration, facilities using mass flow meters must report
mass flow information, facilities using volumetric flow meters must report volumetric flow
information, and facilities using containers must measure the mass or volume of the containers.
3.2.6	Subpart UU Recordkeeping
Facilities must retain quarterly records of any CO2 received for 3 years per 40 CFR
98.3(g).
3.3 Summary of Major Changes Since Proposal
The major changes in this rule since the original proposal are identified in the following
list. The rationale for these and any other significant changes to the rule can be found below or
in "Mandatory Greenhouse Gas Reporting Rule: EPA's Response to Public Comments, Subparts
RR and UU: Injection and Geologic Sequestration of Carbon Dioxide."
EPA has moved all definitions, requirements, and procedures for facilities
conducting CO2 injection only (which both EPA and commenters have referred to
as "Tier 1" facilities for simplicity) into a new subpart, 40 CFR part 98, subpart
UU, and retained all definitions, requirements, and procedures related to facilities
conducting GS (which both EPA and commenters have referred to as "Tier 2"
facilities for simplicity) in 40 CFR part 98, subpart RR.
EPA has removed the requirement that facilities report the amount of C02
injected in 40 CFR part 98, subpart UU (Tier 1) reporting requirements but
retained requirements that facilities subject to this subpart report the amount of
CO2 received and the source of CO2 if known
EPA has established procedures for calculating C02 received in containers.
In 40 CFR part 98, subpart RR, EPA has established eligibility requirements for a
GS R&D project to be exempt from 40 CFR part 98, subpart RR.
In 40 CFR part 98, subpart RR, EPA has retained the requirement that facilities
report the equipment leaks and vented emissions reporting requirement for surface
equipment that could be included in the GS mass balance but removed the
requirement for reporting equipment leaks and vented emissions for all other
surface equipment.
3-6

-------
In 40 CFR part 98, subpart RR, EPA has added an MRV plan requirement for the
delineation of the areas that will be monitored.
In 40 CFR part 98, subpart RR, EPA has clarified the requirements for an
addendum to the annual report and renamed it the monitoring report.
EPA has amended 40 CFR part 78 to include administrative appeals procedures
for EPA decisions made under 40 CFR part 98, subpart RR, such as decisions
relating to eligibility for the R&D exemption under 40 CFR 98.440(d)(4),
decisions relating to a request for discontinuation of reporting under 40 CFR
98.441(b)(2), or MRV plan decisions under 40 CFR 98.448(c).

SECTION 4
ENGINEERING COST ANALYSIS
4.1	Introduction
Using available industry and EPA data to characterize conditions at affected sources,
EPA estimated the costs of complying with final rule. Incremental monitoring, recordkeeping,
and reporting activities were then identified for each type of facility, and the associated costs
were estimated.
4.2	Overview of Cost Analysis
The costs of complying with the rule will vary from one facility to another, depending on
the nature of the CO2 injection activities (GS or non-GS), the MRV plan selected, existing
monitoring, recordkeeping, and reporting activities at the facility, etc. The costs include labor
costs for performing the monitoring, recordkeeping, and reporting activities necessary to comply
with the rule, as well as capital costs related to the implementation of monitoring activities
outlined in the MRV plan for GS sites. All costs referred to in this section are reported in 2008
dollars.
We first provide a general overview of baseline reporting and GS activities. This is
followed by detail on the cost components associated with this information collection; labor
costs (i.e., the cost of labor by facility staff to meet the information collection requirements of
the rule); and capital and operating and maintenance costs (e.g., the cost of purchasing and
installing monitoring equipment or contractor costs associated with providing the required
information).
In section 4.10, we summarize the first year and subsequent year costs by facility and
subpart (Table 4-10) that are used in the economic analysis presented in section 5.
4.3	Baseline Reporting
4.3.1 Introduction
The Environmental Protection Agency developed cost scenarios for reporting of CO2
injection and GS. These rules can affect the number and type of monitoring equipment installed
at the sites and the type and frequency of tests and surveys conducted at the sites. In creating
new EPA regulations, a unit cost analysis and the total cost impact of each of the final
regulations is required by federal law. This provides a basis for a full evaluation of the
incremental costs of the final rule. The purpose of this section is to present the "activity
4-8

-------
baseline," which describes the number and types of injection and GS sites that could be subject
to the rule and the volume of CO2 injections that would be expected.
Through the practice of geological sequestration, CO2 can potentially be sequestered in
underground formations worldwide for thousands of years. Although commercial geologic
sequestration of CO2 has not yet begun in the U.S., several projects such as Sleipner in the North
Sea, In Salah in Algeria, and Weyburn in Alberta have achieved success in recent years. CO2 at
these sites is being sequestered, and technologies to monitor the process have proved effective.
In the U.S., the Department of Energy is supporting approximately 25 sequestration pilot projects
around the country. DOE also has plans to start a number of relatively large scale pilot projects
within coming years.
Geologic sequestration in the U.S. will likely occur in a range of different geologic
settings including: saline reservoirs, oil and gas reservoirs, coal seams, and others. For purposes
of this economic analysis, the costs of specific aspects of geologic sequestration were specified
on the basis of cost per well, per square mile, per sample, or other basis for each project. In
addition, "type cases" were developed for each reservoir type including, in some instances, two
sizes of injection projects for pilot and commercial-size project scales. These include the typical
parameters (e.g. number of monitoring wells and average well depth) for each type of project,
allowing for estimation of total cost per project. In the cost analysis that appears in Chapter 5, a
base case is created assuming relevant monitoring costs are only that which is required under the
UIC rules. Then three cost scenarios for reporting from geologic sequestration sites are
evaluated in terms of technologies and practices and their costs.
4.3.2 Data Sources
In order to evaluate the total costs in the U.S. of the final regulations, it is necessary to
establish an activity baseline forecast of the sequestration activity to which the final regulation
applies. The appropriate forecast for this analysis is the level of GS activity that would be
expected even in the absence of future climate change legislation. While climate change
legislation is currently being debated in Congress, no legislation has been enacted. Even in the
absence of national climate legislation, sequestration activity in the U.S. is planned including:
Research and Development (R&D) projects,
FutureGen Sequestration Site, and
Commercial Sequestration Projects Related to State and Regional Incentive
Programs (in part, funded by DOE)
4-9

-------
4.3.3 Published Data on CO2 Sequestration Projects
4.3.3.1 Planned R&D Projects
The Department of Energy has funded an extensive research effort into geologic
sequestration in the U.S. The project is a collaborative effort with seven regional partnerships.
The research effort is managed by the National Energy Technology Laboratory in Morgantown,
West Virginia. The program has two major components: Core R&D and Demonstration and
Deployment.
According to DOE, the goal is to "develop by 2012 systems that will achieve 90%
capture of CO2 at less than a 10 percent increase in the cost of energy services and retain 99
percent sequestration permanence." 4
The field component of the sequestration research is being carried out by seven regional
partnerships. These partnerships were formed in 2003 and represent consortia of private industry
and government agencies. This effort is tasked with determining the most suitable technologies,
regulations, and infrastructure needs for capture and sequestration.
There are three phases to the work being carried out by the partnerships:
¦	Characterization (2003-2005)
Validation (2005-2009)
¦	Deployment (2009-2017)
The Characterization Phase involved the geologic analysis that resulted in the
development of a National Carbon Sequestration Database and Geographic Information System
(NATCARB). The Validation Phase is currently active and involves such activities as
validation of reservoir simulation methods, data collection for capacity and injectivity, and
demonstration of monitoring technologies. Also being researched are well completion methods,
operations, and abandonment approaches.
The Deployment Stage involves the construction and operation of 8 significant
sequestration projects. These projects are consistent with the Energy Independence and Security
Act of 2007 (EISA), under Title VII, Sec. 702, which requires DOE to conduct at least 7 large
scale sequestration field tests greater than one million tons of CO2 each. These tests are designed
4 Direct Carbon Sequestration: Capturing and Storing Carbon Dioxide, Congressional Research Service, report
RL33801, September, 2007.
4-10

-------
to fully evaluate the potential for commercial scale operations in a range of geological settings.
The tests are planned to have an injection period of up to four years, followed by a lengthy
monitoring period. This phase is designed to evaluate the practical aspects of large scale
injection over a prolonged period of time.
A great deal of progress has been made in the areas of site characterization and
monitoring. The next major phase of the DOE research effort is to provide funding support for a
number of commercial scale sequestration operations with injections of up to one million tons
per year.
Sequestration Related to State and Regional Incentive Programs
A number of states or regions have adopted or plan to adopt regulations to address carbon
dioxide and/or greenhouse gas emissions. Most allow for regulated sources of emissions to meet
compliance requirements through the use of offsets. Although geologic sequestration goals or
criteria may not be specified in each case, the potential exists for sequestration activities to
become an accepted and more prevalent way of meeting greenhouse gas reductions.
The programs or state legislation initiatives are generally in the early stages, and there is
considerable uncertainty in terms of which projects will proceed, and on what schedule. ICF has
researched the CSLF (Carbon Sequestration Leadership Forum) online database and the MIT
online database in our analysis of non-DOE projects. It should be noted, that in these databases,
there are several projects for which startup date and/ or planned injection volumes are not
specified.
Laboratory Research
Over the past several years, DOE and the regional partnerships have carried out an effort
to assess and characterize the CO2 sequestration capacity and potential of the U.S. This effort
has resulted in the publication of a large amount of information on potential by geologic setting
and basin or state. A large amount of GIS data has also been compiled on the geology of
sequestration potential.
In 2008, DOE published the most recent version of the NATCARB (National Carbon)
Atlas. 5 This publication contains maps and data tables documenting their assessment of

Technology Laboratory, Morgantown, WV.

-------
sequestration potential in the U.S. Much of the data behind the NATCARB atlas are either
available in GIS form or will eventually be made available.
4.3.4 Hydrogeologic Settings
Geologic sequestration may take place in a number of settings and lithologies. These
include:
Non-basalt saline reservoirs
Depleted gas fields
Depleted and abandoned oil fields
¦ Enhanced oil recovery (ER)
Enhanced coalbed methane recovery
For the purposes of analyzing this rule, we will focus on the settings that are most likely
affected by the rule, which includes saline reservoirs and oil and gas fields.
4.3.4.1 Non-Basalt Saline Reservoirs
Most significant sedimentary basins in the U.S. contain regionally significant saline
formations that are potential sequestration reservoirs. These are typically sandstone lithologies
with good porosity, containing formation waters of greater than 10,000 mg/L total dissolved
solids. Salinity may be as high as several times that of seawater. Thus, the water is unsuitable
for drinking or agriculture. Saline reservoirs dominate the assessed potential of the U.S. and
worldwide. In addition, because of their wide geographic distribution in the U.S., saline
reservoirs are often in close proximity to CO2 sources, minimizing pipeline transport distance.
Saline reservoirs represent the vast majority of U.S. sequestration potential (approximately 89
percent of total U.S. capacity). 6 It is very likely that saline reservoirs will play a prominent role
in future geologic sequestration.
Sequestration in saline reservoirs has been shown to be effective. The Sleipner field in
the North Sea is the first commercial-scale saline reservoir project. Carbon dioxide is separated
from the gas stream and re-injected into a reservoir at about 800 meters depth. The rate of
6 2007 ICF assessment developed using DOE Atlas volumes and supplementing in several categories.
4-12

-------
injection is 2,700 tons per day or about one million tons per year. 7 It is anticipated that about 20
million tons will eventually be stored. At Sleipner, the plume has been monitored effectively. 8
DOE has extensively studied saline reservoirs for sequestration. Projects include the Frio
Brine pilot in the Texas Gulf Coast and the Mount Simon Sandstone in the Illinois Basin. 9 The
Mount Simon is known to have excellent sequestration potential because of its regional thickness
and reservoir characteristics, and because it has been used extensively for natural gas
sequestration in the Midwest.
4.3.4.2	Depleted Gas Fields and Oil Fields
Depleted gas and oil fields can be excellent candidates for CO2 sequestration. These
represent known structures that have trapped hydrocarbons over geologic time, thus proving the
presence of an effective structure and seal above the reservoir. These fields have also been
extensively studied, there is a large amount of well log and other data available, and the field
infrastructure is already in place. This infrastructure could in some cases be utilized in
sequestration. A potentially problematic aspect of using depleted fields for sequestration is the
presence of a large number of existing wellbores, which can provide leakage pathways.
Typically, oil fields are developed with a closer spacing than gas fields, resulting in a larger
number of existing wells per unit area than in gas fields.
The In Salah Field in Algeria was the world's first project in which CO2 is injected at
commercial scale into a gas reservoir. However, in this case, the gas is injected downdip in an
actively producing gas reservoir. This differs from an abandoned gas reservoir scenario in which
the gas field is no longer producing.
4.3.4.3	Enhanced Recovery of Oil and Gas
Under certain reservoir and fluid conditions, CO2 can be injected into an oil reservoir in a
process called miscible CO2 enhanced oil recovery. The effect of the CO2 is to mobilize the oil

-------
so that it can move more readily to the production wells. As the oil is produced, part of the
injected CO2 is produced with the oil. This CO2 is then separated and re-injected.
In the U.S. most CO2 ER projects are located in the Permian Basin of West Texas, where
projects have been in place for several decades. The source of most of the CO2 is natural CO2
from several fields in Colorado and New Mexico. 10 Some of the injected CO2 is from gas
processing or other sources. The current volume of CO2 injected for CO2 ER is about 2.2 billion
cubic feet per day.
In 2005, CO2 ER operations produced approximately 237,000 barrels of oil per day in the
U.S. About 180,000 barrels per day of that occurred in West Texas, with most of the rest
produced in the Rockies, Mid-Continent, and Gulf Coast. 11
The development of CO2 ER projects has resulted in a great deal of knowledge about the
process and injection well and other technologies have matured and are well understood. In
addition, it is estimated that more than 3,500 miles of high pressure (>1,300 psi) CO2 pipelines
have been built to accommodate these operations. 12
At the Weyburn Field in Saskatchewan, CO2 from the Dakota Gasification Facility in
North Dakota is injected into an oil reservoir for ER and monitoring of CO2 sequestration. Over
the 25 year life of this project, it is expected that about 18 million tons of CO2 will be
sequestered.
4.3.4.4 Enhanced CoalbedMethane Recovery
CO2 can potentially be sequestered in coalbeds through the process of adsorption. CO2
injected as a gas into a coal bed will adsorb onto the molecular structure and be sequestered.
Methane is naturally adsorbed onto coalbeds and coalbed methane now represents a
significant percentage of U.S. natural gas production. Major coalbed methane production areas
include the San Juan Basin of northwestern New Mexico and southwestern Colorado, the Powder
River Basin of eastern Wyoming, and the Warrior Basin in Alabama.

-------
The concept of enhanced coalbed methane recovery is based upon the fact that coalbeds
have a greater affinity for CO2 than methane. Thus, when CO2 is injected into the seam, methane
is liberated and the CO2 is retained. This additional methane represents enhanced gas recovery.
Depending upon depth and other factors, coalbeds may be mineable or unmineable.
Because the process of mining the coal would release any stored CO2, only unmineable coals are
assessed as representing permanent CO2 sequestration. 13
4.3.4.5 Other Hydrogeologic Settings
Basalt flows such as those of the Columbia River Basalts in the Pacific West, are
believed to have the potential for permanent CO2 sequestration. The sequestration process is
geochemical trapping, in which the CO2 reacts with silicates in the basalt to form carbonate
minerals. 14 While research is being carried out on basalt, it is considered unlikely that any
commercial scale sequestration will occur in the foreseeable future due to the unconventional
geology and likely difficulty in monitoring.
The potential to sequester CO2 in organic shale formations is based upon the same
concept as that of coal beds. CO2 will adsorb onto the organic material, displacing methane.
Gas shales have recently emerged as a major current and future source of gas production in the
U.S. These include the Barnett Shale in the Fort Worth Basin, the Fayetteville and Woodford
Shales in the Arkoma Basin, and the Appalachian Devonian Shale. These Devonian and
Mississippian age organic shale formations represent tremendously large volumes of rock. To
date little research has been done on enhanced gas recovery with organic shales. However,
should it prove technically feasible, the U.S. could become one of the major areas worldwide for
this type of sequestration.
4.3.5 Formation Capacity
4.3.5.1 Current DOE Assessment of Sequestration Potential
Through the regional sequestration partnerships, DOE has developed a new national
assessment of sequestration potential. As evaluated by ICF, the DOE Lower-48 total is 8,179
gigatonnes (Gt) of CO2. The range of uncertainty is 3,508 to 12,850 Gt. Most of the

assessment is attributed to saline reservoirs). This assessment is much larger than the prior
assessments also shown on the table.
4.3.6 Geologic Sequestration Rule Activity Baseline
Based upon the above information on what is anticipated for R&D projects, FutureGen,
and state programs, an activity baseline forecast of sequestration activity has been developed.
Because of the uncertainty in which existing ER project might come under subpart RR, three
scenarios have been created and are shown as Tables 4-1. The first scenario assumes that no
existing CO2 ER projects choose to report as facilities conducting GS. The second scenario
assumes that all CO2 ER projects from anthropogenic sources (7 million metric tons per year
coming primarily from natural gas processing plants) choose to report as facilities conducting
GS. The third scenario assumes that all projects from anthropogenic CO2 sources plus one-half
of the remaining CO2 flood projects choose to report as facilities conducting GS. This third
scenario adds up to 23.4 million metric tons per year injected of new (i.e., ignoring recycled
volumes) CO2. These scenarios were chosen to represent a realistic range of ER projects that
might opt-in under subpart RR. The lower bound is what one might expect participation to be
given the lack of comprehensive climate legislation that provides a financial incentive for
sequestration. The upper bound recognizes the fact that not all ER projects are amenable to
sequestration due to reservoir depths and other considerations.
The most comprehensive source of information on US ER projects is the annual survey
conducted by the Oil and Gas Journal. The 105 projects listed in the Oil and Gas Journal 2007
ER survey were grouped by CO2 source type - natural or anthropogenic. CO2 use was allocated
to the projects supplied by each source based on oil production. Anthropogenic sources were
well defined for ER projects in Michigan (Antrim Gas Processing Plant), Wyoming/Colorado
(LaBarge/Shute Creek Gas Processing Plant), central Oklahoma (Enid Fertilizer Plant) and
Kansas (US Energy Partners, Russell Kansas Ethanol Plant) from geographic proximity and
information in published literature. Natural CO2 production from the Jackson Dome in
Mississippi was allocated to the 15 projects in Mississippi and Louisiana based on geographic
proximity and information in published literature. Anthropogenic C02from the Val Verde Gas
Plant in Texas is mixed with CO2 from natural sources and distributed to several fields in the
Permian Basin so there was not a clear delineation of which projects were served by
anthropogenic gas from the Val Verde plant. To estimate the number of facilities served by Val
Verde, the total CO2 use in the Permian Basin from natural sources and Val Verde production
4-16

-------
was summed and the percent of Val Verde production was prorated among the 66 projects in the
Permian Basin. Val Verde CO2 production represents 5.4 % of the total CO2 used in the Permian
Basin, therefore, the equivalent of approximately 4 projects in the Permian Basin are estimated to
use anthropogenic CO2 from Val Verde. For this analysis 2007 CO2 production data for natural
and anthropogenic sources was taken from the (1990-2007) Inventory of U.S. Greenhouse Gas
Emissions and Sinks, and totaled 2.1 bcf/day which differs from the published DOE estimate of
2.6 bcf/day.
Based on the number of projects active in 2007, anthropogenic sources provide
approximately 18% of the mass of CO2 used in ER projects in the US, and represent
approximately 27 % of the CO2 ER projects. These projects result in the additional production of
more than 13 million barrels of oil annually. If only ER projects supplied by anthropogenic
sources opted into the reporting program approximately 29 projects would be included. If all the
ER projects supplied by anthropogenic sources, and half of the projects using natural sources
opted into the reporting program approximately 67 projects would report, representing 1.2
bcf/day (23.4 million metric tons per year) or 59% of all CO2 ER use.

4.3.6.1 Sources of Uncertainty
The activity baseline forecast of sequestration activity represents our best estimate of
what will likely occur in the absence of national climate change legislation. As with any
forecast, there are sources of uncertainty. Categories of uncertainty include:
Number and timing of R&D projects and number of years of injection
Number and timing of FutureGen projects and number of years of injection
Number and timing of State Incentive projects and number of years of injection
Average injection rates
Number of ER proj ects that will be covered
Of the three categories of project, the least uncertainty is associated with the R&D
projects. These projects have been funded and are expected to proceed at close to the
announced schedule.
The DOE FutureGen project site has been chosen (Illinois) but there is still uncertainty
about timing and injection volumes.
Given the number of state and regional initiatives underway it is very likely that projects related
to state incentives will be initiated.
The largest uncertainty over the timeframe of the activity baseline is what may occur at
the national level in terms of climate change legislation. However, any costs associated with
potential future national climate policy cannot be attributed to this subpart currently under
consideration. The activity baseline presented in this document is expressly for the purpose of
evaluating the costs of the subpart RR proposal under existing climate change policies.
4.4 Reporting Costs
4.4.1 Introduction
The purpose of this section is to present the unit cost estimates for the equipment and
services that might be required to comply with the CO2 Injection and GS Reporting rule and the
total incremental annual cost of compliance. A base case is created assuming monitoring costs
are only that which is required under the UIC rules. Then three cost scenarios for reporting from
4-18

-------
geologic sequestration sites are evaluated in terms required technologies and practices and their
costs.
4.4.2 Cost Assumptions and Methodology
No comprehensive source has been identified that provides detailed summaries of the full
range of sequestration project cost components. Estimates of the costs of monitoring equipment,
the number of stations required, and the cost of ongoing monitoring are based upon analysis of
available literature and recent presentations by government and academic research groups and
quotations from vendors. Some specific monitoring costs were obtained at a recent industry
meeting sponsored by the Groundwater Protection Council.15
The costs reported here include capital and operating and maintenance (O&M) including
labor costs. They are based on hypothetical or pro-forma sites for various types of projects such
as saline formation R&D GS projects, saline formation commercial GS projects, and ER GS
projects. The geologic and engineering assumption for these pro-forma projects are the same as
those used by the EPA Office of Water in the final rule, Federal Requirements under the
Underground Injection Control Program for Carbon Dioxide Geologic Sequestration Wells, or
the UIC Class VI final rule for CO2 injection wells16, and are shown below in Table 4-2.

The costs represent price levels in mid 2009, and are presented in 2008 dollars. There
were very steep increases in the costs of equipment, materials and labor used in the construction
of all types of energy infrastructure including power plants, pipelines and oil and gas wells from
2004 through 2008. With the drop of oil and natural gas prices in the Fall of 2008 and the
general economic decline around the world the costs of equipment, materials and labor have
moderated somewhat.
4.4.2.1 Primary Data Sources for Costs
Table 4-3 summarizes the major data sources for costs used by EPA in the analysis
geologic sequestration costs. A wide range of cost data is available from industry survey
publications for costs typically incurred in oil and gas drilling and production operations. This
includes drilling and completion costs by region and depth interval, equipment and operating
4-20

-------
costs, and pipeline costs. Data are available for both the U.S. and Canada. 17 18 19 20The cost of
drilling and equipping wells represents a large component of sequestration costs. The costs of
additional equipment or material specifications for CO2 injection wells are based in part upon
various sources for corrosion resistant materials and specific well components. Cost estimates for
seismic data acquisition are also available from industry publications and presentations.
Labor rates are obtained from the U.S. Bureau of Labor Statistics and from surveys of oil and gas
professional performed by the American Association of Petroleum Geologists (AAPG) and the
Society of Petroleum Engineers (SPE). The number of hours required to carry out the various
characterization or monitoring activities are estimates that have been reviewed by the EPA
workgroup.

The assumed capital costs and the annual operating cost of the various monitoring
technologies whose application might be affected by the rule are shown in Table 4-4 and Table
4-5. The capital costs are annualized using a capital recovery factor of 0.295, 0.142, and 0.075
for projects lasting 4, 10, and 40 years, respectively. The annual O&M costs are added to the
annualized capital costs to determine total annual direct costs. To this is added a 20 percent
overhead and general and administrative cost factor to obtain total annual costs. These are then
divided by the amount assumed to be received each year in the pro-forma project to arrive at
total costs per metric ton of CO2 received. These per-ton costs are then used to estimate total
annual costs for the level of injection expected in the activity baseline.
4.4.3 Monitoring, Reporting, and Verification (MRV) Plan Requirements and
Approval Process
There are two types of sites that will report under this rule, facilities that conduct GS
(subpart RR) and all other facilities conducting CO2 injection (subpart UU). All sites will incur
costs associated with reporting the annual mass of CO2 received, however only facilities
conducting GS will incur the monitoring plan related costs. Under this rule facilities conducting
GS must develop an MRV plan, submit it to EPA for approval, and implement it once approved
by EPA to report the amount of CO2 that has been sequestered. EPA is proposing that each
submitted MRV plan must contain the following components.
1.	Delineation of the maximum monitoring area and the period-specific monitoring areas.
2.	Identification of potential surface leakage pathways for CO2 in the maximum
monitoring area and the likelihood, magnitude, and timing, of surface leakage of CO2 through
these pathways.
3.	A strategy for detecting and quantifying any surface leakage of CO2.
4.	A strategy for establishing the expected environmental baselines.
5.	A summary of the considerations you intend to use to calculate site-specific variables
for the mass balance equation.

4.5 Monitoring Technologies
Deep Monitoring Wells
Deep monitoring wells are typically drilled to monitor the deepest permeable zone above
the caprock. Downhole instrumentation can be used to monitor pressure, temperature, and
conductivity/salinity. Alternatively, U-tube devices can be used to retrieve pressurized samples
for laboratory testing. Other types of monitoring from wells include micro-seismic, cross-well
resistivity, and vertical seismic profiling.
CO2 Flow Meters on Producing Oil and Gas Wells
Meters, probably located after the wellhead separator, that continuously measure the
pressure, temperature and flow rate of the gas from a well. The composition of the gas is
analyzed periodically using a gas chromatograph to determine percent CO2 concentration. The
mass of CO2 passing through the wellhead can then be calculated from the measured quantities.
CO2 Flow and Gas Composition Meters on Producing Oil and Gas Wells
Meters, probably located after the wellhead separator, that continuously measure the
pressure, temperature, flow rate and chemical composition of the gas from a well. The mass of
CO2 passing through the wellhead can then be calculated from the measured quantities. This
differs from the item directly above in that the chemical composition of the gas is being
measured automatically by the meter itself rather through periodically obtaining a sample and
sending it to lab for analysis.
Periodic Sampling and Testing of Injected Fluid
All facilities conducting GS and all other facilities conducting CO2 injection will incur
periodic sampling and testing costs. To estimate the costs, we have applied similar assumptions
that were used in Subpart 00 for sampling and testing of industrial gases. For example, we have
assumed that it takes 12 labor hours to contact an onsite laboratory or offsite vendor and develop
a plan; to collect and send the sample to an onsite or offsite laboratory; and to provide data
invoice if sent offsite. Furthermore, we have assumed that it costs approximately $500 per
sample to collect and conduct the test of chemical composition. In addition to these costs,
facilities conducting GS will additionally incur the costs described in this rule.
4-25

-------
Seismic Surveys
Seismic data acquisition involves the generation and detection of sound waves to
evaluation conditions in the subsurface. Periodic acquisition of seismic data can be used to
detect subsurface CO2 movement within and outside of the reservoir.
Digital Color Infrared Ortho-imagery and Hyper-spectral Imaging
Digital color ortho-imagery and hyper-spectral imaging are airborne remote sensing
technologies that are used to detect changes in vegetation resulting from CO2 leaks.
Hyperspectral sensors look at objects using electromagnetic spectrum. The object is to detect a
specific spectral signature that is known to result from CO2 uptake. The advantage of these
methods is that they can efficiently cover a large surface area.
Airborne or Mobile Remote Sensing Survey
CO2 detectors are commercially available for short closed-path and short open-path
(point) measurements and long open-path (radial line) measurements. Similar detectors have
been integrated into stationary, mobile, and airborne monitoring packages that are commonly
used in combination with high-resolution global positioning system (GPS) to detect and quantify
methane leaks in areas with road access. While these packages have not been widely tested for
CO2, various types of CO2 monitors are commercially available and could be used in these
applications. Such monitoring techniques are likely the leading candidates for monitoring plan
applications because of their low cost and high reliability. The technologies include infrared gas
analyzers (IRGAs, including Fourier transform infrared (FTIR) and non-dispersive infrared
(NDIR) analyzers), tunable diode lasers (TDLs), cavity ring down techniques, and others. The
sample path can range from 10 cm to 1 km, by reflecting a laser beam off retro-reflecting
mirrors. These devices measure the gas concentration, and, when packaged with measurements
of wind speed and wind direction, they measure the total gas flow.
LIDAR (Light Detection and Ranging) involves the transmission of light from an
instrument to a target and the recording of the reflected light to determine some property of the
target. Differential Absorption LIDAR (DIAL) uses two wavelengths of laser to measure CO2.
The wavelengths used are specific to CO2. One wavelength is selected to correspond to a CO2
spectral absorption line, while the other is a non-absorbing wavelength. The difference in
intensity of the two return signals is a measure of concentration.
4-26

-------
Eddy Covariance
Eddy Covariance is a technique whereby high frequency measurements of atmospheric
CO2 concentration at a height above the ground are made by an infra-red gas analyzer along with
measurements of micro-meteorological variables such as wind velocity, direction, humidity, and
temperature. Integration of these data allows derivation of the net CO2 flux over the upwind
footprint, typically square meters to square kilometers in area.
Soil Zone Monitoring with Accumulation Chamber (AC)
Surface CO2 flux is measured using an accumulation chamber. The chamber is made of
stainless steel with an open bottom and is placed at the sampling location. It may be placed
either directly on the ground or on a collar installed in the ground surface. The air is circulated
through the AC and measured with and infra-red gas analyzer.
Vadose Zone Monitoring
The vadose zone is the relatively shallow zone beneath the soil zone that is not saturated
with groundwater. Small diameter probes are installed in the zone and samples are taken. The
CO2 concentration of air samples taken in this zone can be measured by and infrared gas
analyzer.
Monitoring Wells for Sampling of Shallow Water
Shallow monitoring wells may be used to measure the properties of ground water. Such
wells are typically no deeper than several hundred feet.
Estimating Leak Volumes after a Leak is Detected
The monitoring program for facilities conducting GS may detect subsurface leaks and it
will be necessary to estimate the volume of leaks to the surface to comply with the reporting
requirements of this rule. Each site operator will have to devise suitable techniques taking into
account the geology of the sites, the location and nature of the potential leaks and the
performance characteristics of available monitoring and measurement technologies.
It is expected that these estimates may include engineering estimates as well as some
direct measurement and may have a wide margin of uncertainty. It is expected that site
characterization and screening will lead to selection of sites that are suitable for long-term
sequestration and that incidences of leaks to the surface may be infrequent at well-selected and
4-27

-------
well-managed sites. The cost estimates presented here for subsurface leak quantification assume
a two percent chance in one year that any given site will have to implement the leak
quantification strategy described in the site's MRV plan. There are no operating statistics for
CO2 GS from which to draw any citable conclusions on how often leaks to the surface may be
detected, therefore a very conservative estimate was used in order to estimate the potential cost.
If the leak is detected in the subsurface (possibly by anomalous pressure readings in a
monitoring well) the leak volume may be estimated to help calibrate a leak volume to the
surface. Quantification is presumed to be done using engineering calculations supplemented,
when technically feasible, by direct observation/measurement using, for example, a 3-D seismic
survey over the area of the suspected leak. The seismic survey might be able to detect the
location, size and density of the CO2 plume formed by the leak in one or more containment zones
located above the injection zone. The volume of the leak also might be estimated using a
reservoir simulation model of the containment zone calibrated to the pressure readings of the
monitoring wells surrounding the location of the leak. In other words, different volumes of leaks
would be tested in the reservoir simulator to find which leak volume most closely matches the
pressure history observed in the surrounding monitoring wells.
Leaks may also be detected at or near the surface by air, soil gas and water table
monitoring devices. It is possible that some of the monitoring devices, such as eddy covariance,
could themselves be used to estimate leak volumes. Another possible way of estimating the
volume of a leak at the surface is to place a tent over the area of the leak. The tent would be
sealed at the ground by weights or spikes and a calibrated volume of gas such as nitrogen would
be introduced into the tent and allowed to escape through a chimney at the top of the tent. By
measuring the concentration of CO2 in the gases leaving the chimney it is possible to measure the
amount of CO2 leaving the ground in the area of the tent. The tent would have to be moved to
many locations and the process repeated to get a representative sample over the entire area of the
leak. It also would be necessary to correct the readings for natural CO2 fluxes into and out of the
soil.
Many of the leak detection methods for onshore GS sites can be applied to sub-seabed
sites. These include monitoring of the injection well and monitoring of the subsurface CO2
plume: active seismic, passive seismic, sensors in deep monitoring wells, and reservoir
modeling. Though there will be differences in monitoring approaches at sub-seabed GS sites for
leak detection and quantification, the cost estimates are assumed to be comparable.
4-28

-------
Labor Rates
The cost of labor for many of the cost items and for General and Administrative Costs are
based on Society of Petroleum Engineers (SPE) 2008 annual salary survey.21 The average salary
for a petroleum reservoir engineer with 15 years of experience is $143,800. Applying a 1.6
fringe and overhead factor yields an hourly burdened labor cost of $110.62 per hour.
The unit costs values reflect the cost of goods and services that would be purchased by
the entity which owns the facility conducting GS. That entity would have additional General and
Administrative Costs (G&A) on top of those direct costs for goods and services. These G&A
cost are assumed to 20 percent of the direct costs.
4.5.1 Cost Scenarios
There are three cost scenarios (low, medium [or reference], and high) presented in Table
4-6 in terms of which monitoring devices would be used at a facility conducting GS and how
often sampling and measurement would take place. Because each facility conducting GS will
have unique characteristics that may result in the selection of different monitoring techniques,
the application of the monitoring devices are indicated as percents of sites that would be
expected to use each device or technique. Also shown in Table 4-6 are the portions of facilities
that expected to be required to use the device or technique under the UIC Class VI permits and
under UIC Class II permits. The cost impacts of the subpart RR are estimated as the monitoring
and measurement requirements above and beyond the UIC Class II requirements. 22
21	For SPE survey of petroleum engineers see http://www.spe.org/spe-
site/spe/spe/career/salary_survey/08SalarySurveyHighlights.pdf
22	For the purposes of this rule, costs incremental to Class II requirements were estimated for ER projects conducting
GS and costs incremental to the proposed Class VI requirements were estimated for all other GS projects.

4.7 MRV Plan Development Costs
Facilities must develop a monitoring, reporting, and verification (MRV) plan, submit the
MRV plan to EPA, receive an approved MRV plan from EPA, implement the EPA-approved
plan, and submit annual report addenda in accordance with procedures in CFR 98.448(a). The
MRV plan must include a delineation of the monitoring areas; an identification of potential
surface leakage pathways and a risk assessment of leakage of the CO2 through these pathways in
the monitoring area; a strategy for detecting and quantifying any surface leakage of CO2; a
strategy for establishing the expected environmental baselines; and a summary of considerations
made to calculate site-specific variables for the mass balance equation.
Facilities must submit the MRV plan on the schedule described in section 98.448(b).
Facilities must re-submit the MRV plan for EPA approval according to section 98.448(g). An
addendum describing the monitoring program that was implemented, including descriptions of
monitoring anomalies and surface leakage, if any, must be submitted with the next annual report
(March 31 of the subsequent calendar year).
The costs of the developing a MRV plan are reported in Tables 4-8 and 4-9.

4.8	Annual Report Costs
As part of the MRV plan, EPA is requiring annual reporting. Respondents are required to create
an annual report each year. For costing purposes, EPA assumed a 25 page report that require 4
labor hours per page (annual cost is $11,062).
4.9	Other Recordkeeping and Reporting Costs
Additional recordkeeping ($1,700 per entity) and reporting ($500) costs per facility were
also added to each project type.
4.10	Subpart UU Facility Costs
Facilities reporting under subpart UU will incur the following costs:
Monitoring costs (no GS): $2,256 per year
Other recordkeeping costs: $1,700 per year
Other reporting costs: $500 per year
4.11	Summary of Reporting Costs by Facility Type and Subpart
Table 4-10 presents the costs by facility type and subpart.. The first column reports the
facility type and associated subpart. The second and third columns report total costs for the first
year and for subsequent years. The last 4 columns show the range of entity costs under different
scenarios. These facility costs are used to compute the cost-to-sales ratios presented in section 5

4.12 Public Sector Burden
EPA estimates the public sector burden to be $344,000 per year; $55,000 per year is for
verification activities, and remaining costs are for program implementation and developing and
maintaining the data collection system. Program implementation activities include, but are not
limited to, evaluating monitoring plans, developing guidance and training materials to assist the
regulated community, responding to inquires from affected facilities on monitoring and
applicability requirements, and developing tools to assist in determining applicability.

SECTION 5
ECONOMIC IMPACT ANALYSIS
EPA prepares an EIA to provide decision makers with a measure of the social costs of
using resources to comply with a program (EPA, 2000). As noted in EPA's (2000) Guidelines
for Preparing Economic Analyses, several tools are available to estimate social costs and range
from simple direct compliance cost methods to the development of a more complex market
analysis that estimates market changes (e.g., price and consumption) and economic welfare
changes (e.g., changes in consumer and producer surplus). Given data limitations and the size
scope of the final rule, EPA has used the direct compliance cost method as a measure of social
costs23.
5.1 Threshold Analysis
EPA is requiring reporting from all facilities that meet the subpart UU (previously
referred to as "Tier 1" facilities) source category definition and from all facilities that meet the
subpart RR (previously referred to as "Tier 2" facilities) source category definition, at no
threshold. EPA notes that a subpart RR threshold specific to ER projects that are not permitted as
UIC Class VI is unnecessary because such projects can choose to opt-in to the subpart RR source
category by implementing an EPA-approved MRV plan, regardless of quantity of CO2 received.
An all-in reporting threshold will allow the Agency to comprehensively track all CO2
supply (as reported in Suppliers of CO2, subpart PP) that is received. This approach is consistent
with the all-in requirements in the GHG Reporting Program for suppliers of petroleum, natural
gas, and coal-to-liquid products (subparts LL, MM, and NN), producers of industrial gases
(subpart OO), and suppliers of CO2 (subpart PP). It was reasonable to require all of the facilities
in these source categories to report because it would result in the most comprehensive accounting
possible, simplify the rule, and permit facilities to quickly determine whether or not they must
report; the same rationale applies for subparts RR and UU in today's rule. Furthermore, it will
create a uniform burden for all covered facilities, ensuring a level playing field in, and
preventing fragmentation of, the ER and GS sectors. Finally, EPA concluded that the same
approach in both subparts UU and RR maximizes clarity and simplicity for facilities that choose
to opt in from one to the other. The results of the threshold analysis are presented below in Table
5-1 and Table 5-2. For further information on the assumptions underlying the threshold analysis,
please refer to the general technical support document (TSD) for proposal.24
23	See pages 124 and 125 (EPA, 2000).

5.2 National Cost Estimates
The total annualized costs incurred under the rule by these entities would be
approximately $1.1 million (in 2008$) in the first year and $1.0 million in subsequent years.
This includes a public sector burden estimate of $344,000 for program implementation and
verification activities. The typical annual cost for a facility conducting CO2 injection (no GS) is
about $4,000 per year (Table 5-3).

Given uncertainties related to project adoption and the costs of the reporting program,
EPA also considered two other private costs scenarios (one higher and one lower than the
reference cost scenario) in order to assess a range of economic impacts on affected entities
(Table 5-4).

5.3.1 National Cost Estimates Under Alternative Facilities Conducting GS (ER opt
in) Outcomes
Currently, the number of ER operations that would choose to report as facilities
conducting GS (ER opt in) is unknown and EPA could not identify any information or analysis
to estimate this quantity. As a result, two additional scenarios of the have been considered to
represent medium and high outcomes. In the medium scenario, all Anthropogenic CO2 projects
(16) choose to report as facilities conducting GS (ER opt in)(Subpart RR). In the high scenario,
all Anthropogenic CO2 projects (16) and fifty percent of other CO2 projects (32) choose to
report as facilities conducting GS (ER opt in)(Subpart RR).
As shown in Tables 5-5, national cost estimate is $35 million under the medium ER opt
in outcome (first year) and $33 million in subsequent years. As shown in Tables 5-6, national
cost estimate is $103 million under the high ER opt in outcome (first year) and $97 million in
subsequent years.

5.3.2 National Cost Estimates Under Alternative Facilities Conducting GS
(Commercial Saline) Outcomes
As discussed in Section 2, on February 3, 2010, President Obama established the CCS
Task Force. The CCS Task Force, co-chaired by DOE and EPA, was charged with proposing a
plan to overcome the barriers to the widespread, cost-effective deployment of CCS within ten
years, with a goal of bringing 5 to 10 commercial demonstration projects online by 2016.
Additionally, the American Clean Energy Security Act (ACES) and the American Power Act
5-6

-------
(APA) are estimated to induce about 30 percent of fossil-fuel-based electricity generation to
come from power plants with CCS by 2040, rising to approximately 59 percent by 2050 (15
percent and 16 percent respectively of total electricity generation) (EPA, 2010). EPA analysis of
APA projects deployment of over 30GW of CCS in 2030, which corresponds to over 54 550MW
power plants. These modeling exercises show that CCS may play an important role in helping
the United States meet carbon reduction targets.
Given the potential for future deployment of CCS technologies, EPA considered two
additional scenarios of the number of large scale saline aquifer GS (commercial saline) project
deployment by 2050: low (5 projects), medium (9 projects), and high (54 projects). The low
scenario is based on the low end of the range of deployment targeted by the CCS Task Force.
The medium scenario is based on large scale saline project deployment projected in the cost
analysis prepared for the UIC Class VI final rule (73 FR 43492). The high scenario is based on
EPA modeling of the projected deployment of CCS under the American Power Act. The national
first year annual cost estimates increase by $1.6 million under the low outcome; $2.9 million
under the medium outcome, and $17.2 million under the high outcome.
5.3.3 National Cost Estimates: 2011 to 2060 Using Underground Injection Control
Program for Carbon Dioxide Geologic Sequestration Wells (UIC Class VI
Rule) Baseline
EPA also conducted a cost analysis projected between 2011 and 2060. To do this, we
used estimates of the anticipated level of U.S GS activity developed for the Underground
Injection Control Program for Carbon Dioxide Geologic Sequestration Wells (UIC Class VI
Rule) economic analysis (EPA-HQ-OW-2008-0390). The UIC Class VI Rule establishes
minimum Federal requirements under the Safe Drinking Water Act (SDWA) for injection of CO2
for the purposes of long-term storage (also known as GS). The final rule creates a new class of
injection well, Class VI, and sets minimum technical criteria for the purposes of protecting
underground sources of drinking water (USDWs). Additional details about the development of
the Geologic Sequestration Rule baseline can be found in section 3.4 of the UIC Class VI Rule's
economic impact analysis (EPA-HQ-OW-2008-0390) Table 5-7 reports the baseline population
numbers. As shown in Table 5-7, present value of the total costs incurred from 2011 to 2060 is
estimate to be $346 million using a 3 percent discount rate) and $112 million using a 7 percent
discount rate. The annualized values are $13.4 million using a 3 percent discount rate and 50
year period and $8.1 million using a 7 percent discount rate and 50 year period. These numbers
are conservative estimates based on the assumption that the projects report for the entire time
period. In some cases, the plume and pressure front may stabilize before 2060 resulting in fewer
years of reporting costs. Waivered saline and waivered ER refers to the UIC Class VI Rule's
5-7

-------
provision that owners and operators may apply for and receive a waiver of the requirement to
inject below the lowermost underground source of drinking water.

economic analysis (EPA-HQ-OW-2008-0390)
5.4 Economic Impact Analysis
EPA assessed how the regulatory program may influence the profitability of companies
by comparing the monitoring program costs to total sales (i.e., a "sales" test). Given limited data
on commercial geological sequestration operations, EPA restricted the analysis to ER operations.
ER activities account for approximately 90 percent of the project population (83 of 93 facilities).
To do this, we divided the average annualized mandatory reporting costs per field by the
estimated revenue for a representative field.
Sales Test Ratio= Average Cost (Table 5-3)/Estimated revenue (Table 5-6)
5.4.1 Revenue Estimate for a Representative Commercial ER Operation
EPA obtained national production statistics from the latest Department of Energy report
about CO2 ER technologies (DOE, 2009). Data suggest a typical operation produces
approximately 776,000 barrels of oil per year. Using the DOE choice of an average long-term
price of oil ($70), EPA estimated total revenue of $54.3 million per year. To enhance the
transparency of the calculation, we provide data, sources, and methods in Table 5-8.

5.5 Assessing Economic Impacts on Small Entities
The first step in this assessment was to determine whether the rule will have a significant
impact on a substantial number of small entities (SISNOSE). To make this determination, EPA
used a screening analysis that allows us to indicate whether EPA can certify the rule as not
having a SISNOSE. The elements of this analysis included
identifying affected sectors and entities,
selecting and describing the measures and economic impact thresholds used in the
analysis, and
determining SISNOSE certification category.
5.5.1 Identify Affected Sectors and Entities
For the purposes of assessing the impacts of the rule on small entities, we defined a small
entity as (1) a small business, as defined by SBA's regulations at 13 CFR Part 121.201; (2) a
small governmental jurisdiction that is a government of a city, county, town, school district, or
special district with a population of less than 50,000; or (3) a small organization that is any not-
for-profit enterprise that is independently owned and operated and is not dominant in its field.
For the Carbon Dioxide Injection and Geologic Sequestration Reporting Rule, small
entity is defined as a small business as defined by the Small Business Administration's
5-11

-------
regulations at 13 CFR 121.201; according to these size standards, ultimate parent companies
owning oil and gas extraction operations (NAICS 211) are categorized as small if the total
number of employees at the firm is fewer than 500.
The Oil & Gas Journal publishes a list of companies owning active U.S. CO2 ER projects
in 2008 (OGJ, 2008). EPA's initial review of publicly available sales and employment databases
suggest up to 9 of the 23 companies listed in the OGJ survey have fewer than 500 employees.
5.5.2	Develop Small Entity Economic Impact Measures
The sales test examined the average total annualized mandatory reporting costs per ER
field to a representative measure of revenue. Details are provided in section 5.3.
5.5.3	Results of Screening Analysis
The Regulatory Flexibility Act generally requires an agency to prepare a regulatory
flexibility analysis of any rule subject to notice and comment rulemaking requirements under the
Administrative Procedure Act or any other statute, unless the agency certifies that the rule will
not have a significant economic impact on a substantial number of small entities.
After considering the economic impact of the rule on small entities, EPA has concluded
that this action will not have a significant economic impact on a substantial number of small
entities. Currently EPA believes small ER operations will most likely be facilities conducting
CO2 injection (no GS), including Class II ER projects. The average ratio of annualized reporting
program costs to revenues of a typical ER operation likely owned by representative small
enterprises is less than 1%.
Although this final rule will not have a significant economic impact on a substantial
number of small entities, EPA nonetheless took several steps to reduce the impact of this rule on
small entities. For example, monitoring and reporting requirements are built off of the UIC
program. In addition, EPA is requiring equipment and methods that may already be in use by a
facility for compliance with its UIC permit. Also, EPA is requiring annual reporting instead of
more frequent reporting.
During rule implementation, EPA will maintain an "open door" policy for stakeholders to
ask questions about the rule or provide suggestions to EPA about the types of compliance
assistance that will be useful to small businesses. EPA intends to develop a range of compliance
assistance tools and materials and conduct extensive outreach for this final rule.

-------
5.6 Characterization of Benefits of Subpart RR and Subpart UU of the Mandatory
Reporting Rule
Sequestering CO2 in geologic formations has climate benefits and has been recognized as
an important climate mitigation technology. The benefits and costs of this rule were considered
against the backdrop of current regulations, none of which require or provide incentives for
geologic sequestration. As this final rule does not require owners or operators to undertake
geologic sequestration, the benefits directly associated with this rule are more appropriately
related to the reporting of GHG emissions and amounts sequestered. Because quantifying the
benefits of a policy that monitors but does not reduce GHG emissions would be very difficult,
the benefits laid out in this chapter are strictly qualitative. EPA evaluated the benefits of a
reporting system with respect to policy making relevance, transparency issues, and market
efficiency. The following discussion describes one possible means of quantifying benefits and
provides an overview of the qualitative benefits evaluated.
5.6.1 Social Cost of Carbon
The social cost of carbon (SCC) estimates allow benefits from reduced emissions in any
future year to be estimated by multiplying the change in emissions in that year by the SCC value
appropriate for that year. SCC estimates represent the dollar value of a one-ton change in CO2
emissions and reflect underlying assumptions about the growth of emissions and changes in
socio-economic trajectories.
In February 2010, an interagency working group published SCC estimates for use in
regulatory impact analyses of government regulations. The interagency group was composed of
technical experts from a number of Federal agencies. In developing these estimates, the working
group considered public comments, explored the technical literature in relevant fields, discussed
key model inputs and assumptions, and developed estimates of the global benefits of avoiding
climate change.
The interagency group selected four CO2 SCC estimates for use in regulatory analyses.
For 2010, these estimates are $5, $21, $35, and $65 (in 2007 dollars). The first three estimates
are based on the average SCC across models and socio-economic and emissions scenarios at the
5, 3, and 2.5 percent discount rates, respectively. The fourth value, which corresponds to the 95th
percentile SCC estimate at a 3 percent discount rate, represents higher-than-expected impacts
from temperature change further out in the tails of the SCC distribution. The central value is the
average SCC across models at the 3 percent discount rate. For purposes of capturing the
uncertainties involved in regulatory impact analysis, the interagency group emphasized the
importance and value of considering the full range. These SCC estimates also grow over time.
5-13

-------
For instance, the central value increases to $24 per ton of CO2 in 2015 and $26 per ton of CO2 in
2020.
There are a few important caveats to consider when evaluating benefits using SCC, which
are discussed in detail in the Social Cost of Carbon TSD as part of the EPA Light-Duty Vehicle
Greenhouse Gas Emission Standards and Corporate Average Fuel Economy Standards Final
Rule.25
1.	The integrated assessment models used do not completely capture catastrophic and non-
catastrophic impacts.
2.	The integrated assessment models are incomplete in their treatment of adaptation and
technological change.
3.	There is uncertainty in the extrapolation of damages to high temperatures, and
assumptions regarding risk aversion.
Due to the fact that this final rule does not require owners or operators to mitigate climate
impacts through geologic sequestration of CO2, the benefits associated with geologic
sequestration may be better ascribed to regulations that require and/or provide incentives for
geologic sequestration. Based on this analysis and the preceding discussion of caveats, EPA did
not employ SCC estimates to calculate the benefits of this rule. Instead, as discussed below, EPA
evaluated the benefits of this rule qualitatively.
5.6.2 Qualitative Benefits Review
A mandatory reporting system will benefit the public by increased transparency of
facility GHG data. Transparent, public data on GHGs allows for accountability of polluters to
the public stakeholders who bear the cost of the pollution. Citizens, community groups, and
labor unions have made use of data from Pollutant Release and Transfer Registers to negotiate
directly with polluters to lower emissions, circumventing greater government regulation.
Publicly available emissions data also will allow individuals to alter their consumption habits
based on the GHG emissions of producers. In the case of geologic sequestration, the data
requirements and transparency of the rule may also serve to broaden public understanding and
acceptance of the technology as a viable mitigation option.

Rule (May 7, 2010) http://epa.g0v/0taq/climate/regulati0ns.htm#l-l
5-14

-------
The greatest benefit of mandatory reporting of GHGs to government will be realized in
developing future GHG policies. Benefits to industry of GHG monitoring include the value of
having independent, verifiable data to present to the public to demonstrate appropriate
environmental stewardship, and a better understanding of their emission levels and sources to
identify opportunities to reduce emissions. Such monitoring allows for inclusion of standardized
GHG data into environmental management systems, providing the necessary information to
achieve and disseminate their environmental achievements.
Standardization will also be a benefit to industry, once facilities invest in the institutional
knowledge and systems to report GHG data, the cost of monitoring should fall and the accuracy
of the accounting should improve. A standardized reporting program will also allow for
facilities to benchmark themselves against similar facilities to understand better their relative
standing within their industry.

SECTION 6
STATUTORY AND EXECUTIVE ORDER REVIEWS
This section describes EPA's compliance with several applicable executive orders and
statutes during the development of the final Injection and Geologic Sequestration of Carbon
Dioxide Reporting Rule.
6.1	Executive Order 12866: Regulatory Planning and Review
Under Executive Order (EO) 12866 (58 FR 51735, October 4, 1993), this action is a
"significant regulatory action" because it may raise novel legal or policy issues arising out of
legal mandates, the President's priorities, or the principles set forth in the EO. Accordingly,
EPA submitted this action to the Office of Management and Budget (OMB) for review under EO
12866 and any changes made in response to OMB recommendations have been documented in
the docket for this action.
EPA prepared an analysis of the potential costs and benefits associated with this action in
the EIA (EPA-HQ-OAR-2009-0926). A copy of the analysis is available in the docket for this
action and the analysis is briefly summarized here. In the EIA, EPA has identified the regulatory
options considered, their costs, the emissions that would likely be reported under each option,
and explained the selection of the option chosen for the rule. The costs of the rule are reported in
Section 4 of the EIA, and the economic impacts and qualitative benefits assessment are reported
in Section 5 of the EIA. Overall, EPA has concluded that the costs of the Injection and Geologic
Sequestration of Carbon Dioxide Reporting Rule are justified by the potential benefits of more
comprehensive information about CO2 injection. In the absence of new climate policy, the total
annualized cost of the rule will be approximately $1.1 million (in 2008$) during the first year of
the program and $1.0 million in subsequent years (including 344,000 of programmatic costs to
the Agency).
6.2	Paperwork Reduction Act
The information collection requirements in this final rule have been submitted for
approval to the Office of Management and Budget (OMB) under the Paperwork Reduction Act,
44 U.S.C. 3501 et seq. The Information Collection Request (ICR) document prepared by EPA
has been assigned EPA ICR number 2372.02.
EPA has identified the following goals of the GHG reporting system:
6-1

-------
Obtain data that is of sufficient quality that it can be used to analyze and inform
the development of a range of future climate change policies and potential
regulations.
Create reporting requirements that are, to the extent possible and appropriate,
consistent with existing GHG reporting programs in order to reduce reporting
burden for all parties involved.
The information from CO2 injection and geologic sequestration facilities will allow EPA
to make well-informed decisions about whether and how to use the CAA to regulate these
facilities and encourage voluntary reductions. Because EPA does not yet know the specific
policies that will be adopted, the data reported through the mandatory reporting system should be
of sufficient quality to inform policy and program development. Also, consistent with the
Appropriations Act, the reporting rule covers a broad range of sectors of the economy including
sites that inject and store CO2.
This information collection is mandatory and will be carried out under CAA section 114.
Information identified and marked as CBI will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2. However, emissions information collected under CAA
section 114 generally cannot be claimed as CBI and will be made public.26
The projected cost and hour burden for non-Federal respondents is $7.0 million and 9,416
hours per year. The estimated average burden per response is 56.6 hours; the frequency of
response is annual for all respondents that must comply with the rule's reporting requirements;
and the estimated average number of likely respondents per year is 93. The cost burden to
respondents resulting from the collection of information includes the total capital and start-up
cost annualized over the equipment's expected useful life (averaging $717,000 per year) a total
operation and maintenance component (averaging $5.3 million per year), and a labor cost
component (averaging $1.0 million per year).
Burden is defined at 5 CFR part 1320.3(b). Although not included in the primary
economic analysis, the costs and burdens to the ER opt ins were estimated using an alternate cost
scenario and in this section EPA is giving its best estimates of likely costs and burdens, including
to voluntary reporters, as required by the Paperwork Reduction Act. These cost numbers differ
26 Although CBI determinations are usually made on a case-by-case basis, on July 7, 2010, EPA published a
proposed rule (75 FR 39094) relating to CBI determinations for the data collected under the GHG Reporting
Program (40 CFR part 98).
6-2

-------
from those shown elsewhere in the EIA for this final rule because ICR costs represent the
average cost over the first three years of the rule, but costs are reported elsewhere in the EIA for
the first year of the rule and for subsequent years of the rule. Also, the ICR focuses on
respondent burden only, while the EIA for this final rule includes EPA Agency costs as well. An
agency may not conduct or sponsor, and a person is not required to respond to, a collection of
information unless it displays a currently valid OMB control number. The OMB control
numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9. When this ICR is
approved by OMB, the Agency will publish a technical amendment to 40 CFR part 9 in the
Federal Register to display the OMB control number for the approved information collection
requirements contained in this final rule.
6.3 Regulatory Flexibility Act (RFA)
The RFA generally requires an agency to prepare a regulatory flexibility analysis of any
rule subject to notice and comment rulemaking requirements under the Administrative Procedure
Act or any other statute unless the agency certifies that the rule will not have a significant
economic impact on a substantial number of small entities. Small entities include small
businesses, small organizations, and small governmental jurisdictions.
For purposes of assessing the impacts of today's rule on small entities, small entity is
defined as: (1) A small business as defined by the Small Business Administration's regulations
at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county,
town, school district or special district with a population of less than 50,000; and (3) a small
organization that is any not-for-profit enterprise which is independently owned and operated and
is not dominant in its field.
This rule will not have a significant economic impact on a substantial number of small
entities. Currently EPA has determined that small ER operations will most likely be facilities
conducting CO2 injection only, including UIC Class II ER projects, which are only required to
report under subpart UU. The average ratio of annualized reporting program costs to revenues of
a typical ER operation likely owned by representative small enterprises is less than 1 percent.
Although this final rule will not have a significant economic impact on a substantial
number of small entities, EPA nonetheless took several steps to reduce the impact of this rule on
small entities. For example, monitoring and reporting requirements are built off of the UIC
program. In addition, EPA is requiring equipment and methods that may already be in use by a
facility for compliance with its UIC permit. Also, EPA is requiring annual reporting instead of
more frequent reporting.
6-3

-------
During rule implementation, EPA will maintain an "open door" policy for stakeholders to
ask questions about the rule or provide suggestions to EPA about the types of compliance
assistance that will be useful to small businesses. EPA intends to develop a range of compliance
assistance tools and materials and conduct extensive outreach for this final rule.
6.4	Unfunded Mandates Reform Act (UMRA)
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), P.L. 104-4, establishes
requirements for Federal agencies to assess the effects of their regulatory actions on State, local,
and Tribal governments and the private sector. Under CAA section 202 of the UMRA, EPA
generally must prepare a written statement, including a cost-benefit analysis, for final rules with
"Federal mandates" that may result in expenditures to State, local, and Tribal governments, in
the aggregate, or to the private sector, of $100 million or more in any one year.
This final rule does not contain a Federal mandate that may result in expenditures of $100
million or more for State, local, and Tribal governments, in the aggregate, or the private sector in
any one year. Overall, EPA estimates that the total annualized costs of this final rule are
approximately $1.1 million (in 2008$) during the first year of the program and $1.0 million in
subsequent years (including $344,000 of programmatic costs to the Agency). Thus, this final
rule is not subject to the requirements of CAA sections 202 or 205 of the UMRA.
This final rule is also not subject to the requirements of CAA section 203 of the UMRA
because it contains no regulatory requirements that might significantly or uniquely affect small
governments. Facilities subject to this final rule include facilities that inject CO2 for enhanced
recovery, and those that sequester CO2. None of the facilities currently known to undertake
these activities are owned by small governments.
6.5	Executive Order 13132: Federalism
Executive Order 13132, entitled "Federalism" (64 FR 43255, August 10, 1999), requires
EPA to develop an accountable process to ensure "meaningful and timely input by State and
local officials in the development of regulatory policies that have Federalism implications."
"Policies that have Federalism implications" is defined in the EO to include regulations that have
"substantial direct effects on the States, on the relationship between the national government and
the States, or on the distribution of power and responsibilities among the various levels of
government."
This final rule does not have Federalism implications. It will not have substantial direct
effects on the States, on the relationship between the national government and the States, or on
6-4

-------
the distribution of power and responsibilities among the various levels of government, as
specified inEO 13132.
This regulation applies to public- or private-sector facilities that inject CO2 underground.
Few government facilities would be affected. This regulation applies directly to facilities that
inject CO2 underground. It does not apply to governmental entities unless the government entity
owns a facility that injects and/or sequesters CO2 underground. This regulation also does not
limit the power of States or localities to collect GHG data and/or regulate GHG emissions. Thus,
EO 13132 does not apply to this final rule. However, as it is EPA's policy to promote
communication between the Agency and State and local governments, EPA specifically solicited
comments on the proposed rule from State and local officials.
6.6 Executive Order 13175: Consultation and Coordination with Indian Tribal
Governments
Executive Order 13175, entitled "Consultation and Coordination with Indian Tribal
Governments" (59 FR 22951, November 6, 2000), requires EPA to develop an accountable
process to ensure "meaningful and timely input by Tribal officials in the development of
regulatory policies that have Tribal implications."
This action does not have Tribal implications, as specified in EO 13175 (65 FR 67249,
November 9, 2000). This regulation applies directly to facilities that inject and/or sequester CO2
underground. EPA analyzed the facilities expected to be affected by this rule and did not find
that any facilities expected to be affected by the rule are likely to be owned by tribal
governments. In addition, EPA did not hear from any Tribal governments contradicting this
analysis. Thus, EO 13175 does not apply to this final rule.
Although EO 13175 does not apply to this final rule, EPA sought opportunities to provide
information to Tribal governments and representatives during development of the GHG reporting
rule. In consultation with EPA's American Indian Environment Office, EPA's outreach plan
included tribes. EPA conducted several conference calls with Tribal organizations during the
proposal phase of the GHG reporting rule. For example, EPA staff provided information to
tribes through conference calls with multiple Tribal working groups and organizations at EPA
that interact with tribes and through individual calls with two Tribal board members of TCR. In
addition, EPA prepared a short article on the GHG reporting rule that appeared on the front page
of a Tribal newsletter—Tribal Air News—that was distributed to EPA/Office of Air Quality
Planning & Standards' network of Tribal organizations. EPA gave a presentation on various
climate efforts, including the GHG Reporting Program, at the National Tribal Conference on
6-5

-------
Environmental Management on June 24-26, 2008. In addition, EPA had copies of a short
information sheet distributed at a meeting of the National Tribal Caucus. See the "Summary of
EPA Outreach Activities for Developing the GHG reporting rule," in Docket No. EPA-HQ-
OAR-2008-0508-055 for a complete list of Tribal contacts. EPA participated in a conference
call with Tribal air coordinators in April 2009 and prepared a guidance sheet for Tribal
governments on the proposed GHG reporting rule. It was posted on the GHG Reporting
Program website and published in the Tribal Air Newsletter.
6.7	Executive Order 13045: Protection of Children from Environmental Health Risks
and Safety Risks
This action is not subject to EO 13045 because it does not establish an environmental
standard intended to mitigate health or safety risks, and it is not an economically significant
regulatory action under EO 12866.
6.8	Executive Order 13211: Actions that Significantly Affect Energy Supply,
Distribution, or Use
This final rule is not a "significant energy action" as defined in EO 13211 (66 FR 28355,
May 22, 2001) because it is not likely to have a significant adverse effect on the supply,
distribution, or use of energy. Further, EPA has concluded that this rule is not likely to have any
adverse energy effects. This final rule relates to monitoring, reporting and recordkeeping at
facilities that inject and/or sequester CO2 underground and does not impact energy supply,
distribution or use. Oil and gas operations that use CO2-ER are only required to report under
subpart UU, unless they opt into subpart RR to establish that CO2 is being geologically
sequestered. Therefore, we conclude that this rule is not likely to have any adverse effects on
energy supply, distribution, or use.
6.9	National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement Act of 1995
(NTTAA), Public Law No. 104-113 (15 U.S.C. 272 note) directs EPA to use voluntary
consensus standards in its regulatory activities unless to do so would be inconsistent with
applicable law or otherwise impractical. Voluntary consensus standards are technical standards
(e.g.. materials specifications, test methods, sampling procedures, and business practices) that are
developed or adopted by voluntary consensus standards bodies. NTTAA directs EPA to provide
Congress, through OMB, with explanations when the Agency decides not to use available and
applicable voluntary consensus standards. This rulemaking involves technical standards. EPA
developed no new measuring device standard. Rather we allow the use of an appropriate
6-6

-------
standard method published by a consensus-based standards organization if such a method exists;
or an industry standard practice.
6.10	Executive Order 12898: Federal Actions to Address Environmental Justice in
Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629, February 16, 1994) establishes federal executive
policy on environmental justice. Its main provision directs federal agencies, to the greatest
extent practicable and permitted by law, to make environmental justice part of their mission by
identifying and addressing, as appropriate, disproportionately high and adverse human health or
environmental effects of their programs, policies, and activities on minority populations and low-
income populations in the United States.
EPA has determined that the final rule will not have disproportionately high and adverse
human health or environmental effects on minority or low-income populations because it does
not affect the level of protection provided to human health or the environment. The final rule
does not affect the level of protection provided to human health or the environment because it is
a rule addressing information collection and reporting procedures only.
6.11	Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business
Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take
effect, the agency promulgating the rule must submit a rule report, which includes a copy of the
rule, to each House of the Congress and to the Comptroller General of the United States. EPA
will submit a report containing this rule and other required information to the U.S. Senate, the
U.S. House of Representatives, and the Comptroller General of the U.S. prior to publication of
the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published
in the Federal Register. This action is not a "major rule" as defined by 5 U.S.C. 804(2). This
rule will be effective [INSERT THE DATE 30 DAYS AFTER PUBLICATION OF THIS
FINAL RULE IN THE FEDERAL REGISTER OR DECEMBER 31, 2010, WHICHEVER IS
EARLIER],

SECTION 7
CONCLUSIONS
EPA is promulgating a regulation to require monitoring and reporting from facilities that
conduct carbon dioxide (CO2) injection and geologic sequestration (GS). This rule does not
require control of greenhouse gases (GHGs), rather it requires only monitoring and reporting of
GHGs.
7.1 Summary of Selected Regulatory Alternative
This final rule amends 40 CFR part 98 to add reporting requirements covering facilities
that conduct geologic sequestration of CO2 (40 CFR part 98, subpart RR) and all other facilities
that conduct injection of CO2 (40 CFR part 98, subpart UU).1 GS is the long-term containment
of a CO2 stream in subsurface geologic formations. This data will, among other things, inform
Agency decisions under the CAA related to the use of carbon dioxide capture and geologic
sequestration (CCS) for mitigating GHG emissions.
Subpart RR information will enable EPA to monitor the growth and efficacy of GS (and
therefore CCS) as a GHG mitigation technology over time and to evaluate relevant policy
options. Furthermore, where enhanced oil and gas recovery (ER) projects are reporting under 40
CFR part 98, subpart RR, EPA will be able to evaluate ER as a non-emissive end use. Under 40
CFR part 98, subpart UU, EPA will be able to reconcile information obtained from this rule with
data obtained from 40 CFR part 98, subpart PP on CO2 supplied to the economy.
The rule was proposed by EPA on April 12, 2010. One public hearing was held on April
19, 2010, and the sixty day public comment period ended June 11, 2010. This rule takes into
consideration comments received during the comment period and finalizes the monitoring and
reporting requirements for facilities conducting GS and all other facilities conducting CO2
injection.
This final rule does not address whether data reported under 40 CFR part 98, subparts RR
or UU will be released to the public or will be treated as CBI. EPA published a proposed rule on
confidentiality determination on July 7, 2010 (75 FR 39094) that addressed this issue. In that
action, EPA proposed which specific data elements may be released to the public and which
1 EPA has moved all definitions, requirements, and procedures for facilities conducting C02 injection only (which
both EPA and commenters have referred to as "Tier 1 " facilities for simplicity) into a new subpart, 40 CFR part
98, subpart UU, and retained all definitions, requirements, and procedures related to facilities conducting GS
(which both EPA and commenters have referred to as "Tier 2" facilities for simplicity) in 40 CFR part 98,
subpart RR.

would be treated as CBI. EPA received several comments on that proposal under that action, and
is in the process of considering these comments. A final rule and determination will be issued
before any data are released.

7.2 Estimated Costs and Impacts of the Mandatory GHG Reporting Program
Under the rule, EPA estimates that 93 facilities would be covered by the rule. The total
annualized costs incurred under the rule by these entities would be approximately $1.1 million
(in 2008$) in the first year and $1.0 million in subsequent years. This includes a public sector
burden estimate of $344,000 for program implementation and verification activities. These costs
represent less than 0.0001% of 2008 gross domestic product; overall, EPA does not believe the
rule will have a significant macroeconomic impact on the national economy or on small entities
within those sectors.
7.2.1 Alternative Scenarios Considered
7.2.1.1	Facilities Conducting GS (ER opt in) Outcomes
Currently, the number of ER operations that would choose to report as facilities
conducting GS (ER opt in) is unknown and EPA could not identify any information or analysis
to estimate this quantity. As a result, two additional scenarios of the have been considered to
represent medium and high outcomes. In the medium scenario, all Anthropogenic CO2 projects
(16) choose to report as facilities conducting GS (ER opt in) (Subpart RR). In the high scenario,
all Anthropogenic CO2 projects (16) and fifty percent of other CO2 projects (32) choose to
report as facilities conducting GS (ER opt in) (Subpart RR). As shown in Tables 5-5, national
cost estimate is $35 million under the medium ER opt in outcome (first year) and $33 million in
subsequent years. As shown in Tables 5-6, national cost estimate is $103 million under the high
ER opt in outcome (first year) and $97 million in subsequent years.
7.2.1.2	Facilities Conducting GS (Commercial Saline) Outcomes
Given the potential for future deployment of CCS technologies, EPA considered two
additional scenarios of the number of large scale saline aquifer GS (commercial saline) project
deployment by 2050: low (5 projects), medium (9 projects), and high (54 projects). The low
scenario is based on the low end of the range of deployment targeted by the CCS Task Force.
The medium scenario is based on large scale saline project deployment projected in the cost
analysis prepared for the UIC Class VI final rule (73 FR 43492). The high scenario is based on
EPA modeling of the projected deployment of CCS under the American Power Act. The national
first year annual cost estimates increase by $1.6 million under the low outcome; $2.9 million
under the medium outcome, and $17.2 million under the high outcome.
