**Flaring Versus Venting To Reduce Greenhouse Gas Emissions in the**  **Outer Continental Shelf; Public Workshop** 

**AGENCY :**  Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE), Interior.

**ACTION :**  Public workshop.

**SUMMARY :**  Bureau of Ocean Energy Management, Regulation and Enforcement is announcing a workshop to discuss possible new requirements on flaring versus venting of natural gas in the Outer Continental Shelf (OCS), when such atmospheric release of natural gas is necessary and in compliance with regulations. The main focus of this workshop will be aimed at the potential reduction of Greenhouse Gas (GHG) emissions.

**DATES :**  The workshop will be held on Wednesday, March 30, 2011, from 9 a.m. to 12 p.m.

**ADDRESSES :**  The workshop will be held at 1201 Elmwood Park Blvd., New Orleans, Louisiana.

**SUPPLEMENTARY INFORMATION :**  Subpart K Rulemaking

On March 6, 2007, the U.S. Department of the Interior (Department) published a Notice of Proposed Rulemaking (NPR) in the Federal Register (72 FR 9884). This NPR requested comments on proposed revisions to 30 CFR part 250, subpart K, Oil and Gas Production Requirements. The Department conducted analyses to assess the costs and benefits of requiring flare/vent meters and of requiring flaring instead of venting.

• The first analysis supported the recommendation to require meters, provided that the facilities process more than 2,000 barrels of oil per day (BOPD). This requirement was included in the final rule, published on April 19, 2010, in the Federal Register (75 FR 20271), Oil and Gas Production Requirements, at 30 CFR part 250, subpart K.

• The second analysis indicated that a regulatory change to require flaring instead of venting may be appropriate. However, the cost of implementing this requirement could be significant, and input from potentially affected parties is necessary. We requested comments on this issue in the proposed rule.

• Commenters pointed out that converting existing facilities that are equipped to vent natural gas to be able to flare natural gas may require significant redesign for safety.

• They also pointed out that there are many factors in determining whether to flare natural gas or vent natural gas when designing a facility. These factors include the operating philosophy, nature and type of reservoir, facility design limitations or capabilities, operating practices, safety, and
economics.

• Industry comments also recommended that, in addition to considering requiring flaring instead of venting, BOEMRE should work with them to find ways to reduce overall natural gas emissions.

• Industry representatives also stated that a requirement for flaring instead of venting should be only for new facilities.

Request for a Workshop

Commenters requested that BOEMRE hold a workshop to discuss the issue. BOEMRE plans to work directly with interested parties to study the costs and benefits (especially GHG benefits) of requiring that companies flare the natural gas, whenever possible, when flaring or venting is necessary.

Therefore, we are holding a workshop to discuss the issue of flaring instead of venting. This workshop and additional cost-benefit analysis will consider GHG issues associated with flaring and venting. The workshop will assist BOEMRE to determine how to best implement a General Accounting Office (GAO) recommendation (see GAO Report below).

Proposed Rulemaking

BOEMRE will decide how to move forward with rulemaking on flaring natural gas after we hold the workshop. Our next step would likely be a proposed rule.

GAO Report

In July 2004, the GAO issued a report on world-wide emissions from vented and flared natural gas titled, Natural Gas Flaring and Venting—Opportunities to Improve Data and Reduce Emissions (GAO–04–809). This report is available on the GAO Web site at: http:// www.gao.gov/new.items/d04809.pdf. This report reviewed the flaring and venting data available, the extent of flaring and venting, their contributions to GHG emissions, and opportunities for the Federal Government to reduce flaring and venting.

The report concluded that more accurate records were needed on flaring and venting to determine the amount of the resource that is lost and the volume of GHG emissions these practices contribute to the atmosphere each year. The report also stated that the impact of methane (a naturally occurring gas released during venting) on the earth’s atmosphere is about 23 times greater than that of carbon dioxide (a byproduct of flaring). The GAO made two recommendations to the Secretary of the Interior: (1) consider the cost and benefit of requiring that companies flare the natural gas, whenever possible, when flaring or venting is necessary; and (2) consider the cost and benefit of requiring that companies use flaring and venting meters to improve oversight. In addition, there was a recommendation to the Secretary of Energy to consider consulting with the Environmental Protection Agency (EPA), BOEMRE, and Bureau of Land Management, on how to best collect separate statistics on flaring and venting. In 2005, BOEMRE performed a cost-benefit analysis on the possible requirement to flare instead of vent. The agency determined that it was not appropriate to mandate flaring at that time, but noted that this topic would be pursued further. In light of developments since 2005, BOEMRE has determined that a workshop to hear public concerns is appropriate and a new cost-benefit analysis is needed. Note also that the other two GAO recommendations (to consider a requirement to install flare/vent meters and to consider a requirement to report flare volumes separately from vent volumes) were implemented via the April 19, 2010, publication of regulations at 30 CFR Part 250, subpart K (75 FR 20271).

Oil and Gas Industry Contributions to GHG Emissions in the Federal OCS

Most natural gas production involves extracting natural gas from wells drilled into underground gas reservoirs; however, some natural gas is generated as a by-product of oil production. During oil and natural gas production, it may become necessary to burn or release natural gas for a number of operational reasons, including safety. These operations may be associated with unloading or cleaning of a well, production testing, or relieving system pressure during equipment failure. The controlled burning of natural gas is called flaring, while the controlled release of unburned gases directly into the atmosphere is called venting. Most flaring and venting occurs at the end of


### 81951 Federal Register / Vol. 75, No. 249 / Wednesday, December 29, 2010 / Proposed Rules

a flare stack or boom which ensures that natural gas can be safely disposed of in emergency and shutdown situations. It is virtually impossible to produce oil and natural gas without any flaring or venting, and it would be impractical to shut in production every time an upset occurs. It is estimated that operators in the Gulf of Mexico OCS flare and vent less than 0.5 percent of the gas produced, making this area a world leader in the conservation of natural gas

resources.

BOEMRE regulates air emissions as mandated by the OCS Lands Act. Under the 1990 Clean Air Act Amendments, BOEMRE has jurisdiction over Gulf of Mexico OCS emission sources westward of 87 ° 30 ′ W longitude, and the EPA has jurisdiction over those eastward of

87 ° 30′ W longitude. The EPA also has jurisdiction over emissions in the OCS of Alaska, the Atlantic, and the Pacific. BOEMRE regulates OCS emissions to assure compliance with the National Ambient Air Quality Standards and to prevent significant air quality deterioration in onshore areas. BOEMRE regulates activities that have the potential to affect air quality at the onshore areas.

Both flaring and venting on the OCS are highly regulated by BOEMRE. Federal regulations at 30 CFR 250, subpart K specify the limited circumstances under which offshore oil and gas operators may flare or vent natural gas. In the Federal OCS, BOEMRE requires operators to continuously record these volumes and report them each month. These regulations strictly limit the amount of time operators may flare or vent. In some cases, operators request additional time in order to complete equipment repairs. BOEMRE evaluates each of these requests on a case-by-case basis, primarily focusing on environmental, safety, and conservation aspects. BOEMRE also performs onshore air quality impacts analyses to prevent significant onshore air quality deterioration from OCS activities.

BOEMRE continuously strives to improve its oversight of OCS flaring and venting. New regulations, published in April 2010, require operators to install flare/vent meters on large platforms and also to report gas flared separately from gas vented. These regulatory changes will provide more accurate measurements of GHG emissions.

Given the existing restrictions on OCS flaring and venting, there is minimal opportunity to further reduce the overall volume of gas flared and vented. However, the global warming potential of GHG emissions could be reduced if BOEMRE were to require operators to flare instead of vent (when the release of natural gas is necessary). Such a requirement would reduce the global warming potential of GHG emissions by converting most methane to carbon dioxide as it is released. The workshop will address this topic.

It is difficult to estimate the impact that flaring instead of venting would have on GHG emissions until BOEMRE gathers the more accurate data required by new regulations (which require the installation of flare/vent meters and the separate reporting of flare and vent volumes). Furthermore, it is impractical, if not impossible, to eliminate all venting. Even if 100 percent of the released OCS gas could be flared instead of vented, the impact on total U.S. GHG emissions would be very small.

In 2008, U.S. GHG emissions totaled

7.668 x 10 9 tons of carbon dioxide equivalent (CO 2e). Of that total, only

30.9 x 10 6 tons of CO 2e, or 0.40 percent, were related to OCS oil and gas production (including platform and non-platform sources), and flaring and venting activities represent only a fraction of that amount.

Based on several assumptions, estimates, and existing analyses, BOEMRE roughly approximated the impact that might occur if it were to mandate flaring over venting. These estimates indicate that such a requirement would reduce total U.S. GHG emissions by less than 0.05 percent. However, the accuracy of these estimates will improve over the next few years now that regulations at 30 CFR part 250, subpart K have been implemented. Reported OCS flare and vent volumes could increase or decrease based solely on improved reporting accuracy. In any event, further analysis may shed light on whether flaring rather than venting natural gas is cost effective from a GHG perspective, even if the total amount of GHGs is small.

Workshop Presentations

In order to assist BOEMRE, assess the need for regulations on this topic, and ascertain the framework for any such regulations, interested parties are encouraged to register for the workshop and present their recommendations on the following topics:

• The impact of flaring versus venting on GHG emissions;

• If BOEMRE requires flaring instead of venting, whether this mandate should apply to all (new and existing) facilities, apply only to facilities emitting above a certain threshold, and what acceptable threshold levels should be;

• Technical and/or economical feasibility of retrofitting some or all existing facilities with flare tips; • Flare tip technology and/or combustion efficiency;

• Emissions reduction;

• Existing worldwide best practices
that could reduce GHG emissions from flaring and venting;

• Safety issues associated with requiring flaring instead of venting on OCS facilities;

• Variables and/or methods that
should be used to evaluate the cost versus benefit of flaring instead of venting; and

• Equipment (specific components) that have to emit natural gas locally instead of the gas being routed to a flare tip due to safety, practical, or other reasons, as well as acceptable/or recommended volumes of natural gas
emissions that would be associated with this equipment.

Note that the primary focus of this workshop will be to receive feedback from all interested and potentially affected parties in advance of any rulemaking. BOEMRE anticipates that the agenda of the workshop will be predominantly presentations by those interested parties in order for BOEMRE to receive their input. In order to present at and/or attend this workshop, you must register in advance.

**ACTION :**  Proposed rules; correction.

**SUMMARY :**  NHTSA and EPA published in the Federal Register of November 30, 2010, proposed rules to establish a comprehensive Heavy-Duty National Program that will increase fuel efficiency and reduce greenhouse gas emissions for on-road heavy-duty vehicles, responding to the President’s directive on May 21, 2010, to take coordinated steps to produce a new generation of clean vehicles. That document inadvertently contained some incorrect fuel consumption values in NHTSA-specific tables in the preamble that resulted from using an incorrect conversion factor for determining CO 2 emissions to equivalent fuel consumption for gasoline fuel. That document also contained some rounding errors in NHTSA-specific tables in the preamble. This document corrects the rounding errors by adopting a uniform rounding approach for all fuel consumption equivalents for those NHTSA-specific tables and makes the appropriate corrections to the
conversions.

That document inadvertently contained some incorrect fuel consumption values in NHTSA-specific tables in the preamble that resulted from using an incorrect conversion factor for determining CO 2 emissions to equivalent fuel consumption for gasoline fuel. The correct values that should have been used in the document are a factor of 1,018 grams of CO 2 per gallon of diesel for conversion of diesel fuel, and a factor of 8,887 grams of CO 2 per gallon of gasoline for gasoline.

That document also contained some rounding errors in NHTSA-specific tables in the preamble. This document corrects the rounding errors by adopting a uniform rounding approach for all fuel consumption equivalents and makes the
