Notice of public meeting.


The U.S. Department of Energy (DOE) is considering establishing energy conservation standards for commercial and industrial compressors. To date, DOE has considered energy conservation standards only for compressors intended to compress air, rather than natural gas. As a result, DOE's current efforts have focused on air compressors. However, DOE is also aware that compressors used to compress natural gas may also use a substantial amount of energy. To improve its understanding of both the technology and market of natural gas compressors, DOE will hold Start Printed Page 70798a public meeting to discuss and receive further comments and supporting data about the characteristics and energy use of this equipment as described in the request for information (RFI) published by DOE on August 5, 2014 (79 FR 45377).

DOE may also opt to publish supplementary information prior to the meeting for stakeholder review. If so, DOE would announce the arrival of that information by publishing a notice of data availability in the Federal Register.


Meeting: DOE will hold a public meeting on December 17, 2014, from 9:00 a.m. to 1:30 p.m. in Washington, DC. In addition, DOE plans to broadcast the public meeting via webinar. You may attend the public meeting either in person or via webinar.

Comments: DOE will accept written comments, data, and other related information about the RFI before and after the public meeting, but not later than January 12, 2015. Interested parties are encouraged to submit comments electronically.

Any person requesting to present an oral statement for the record must notify DOE prior to 4:00 p.m., December 3, 2014, and provide to DOE an electronic copy of the statement with the presenter's name and, if appropriate, the organization the presenter represents, prior to 4:00 p.m., December 10, 2014.


A copy of the RFI is available at:​#!documentDetail;​D=​EERE-2013-BT-STD-0040-0023.

The public meeting will be held at the U.S. Department of Energy, Forrestal Building, Room 4A-104, 1000 Independence Avenue SW., Washington, DC 20585-0121.

Title III of the Energy Policy and Conservation Act, 42 U.S.C. 6291, et seq., (EPCA) sets forth a variety of provisions designed to improve the energy efficiency of products and commercial equipment. (All references to EPCA refer to the statute as amended through the American Energy Manufacturing Technical Corrections Act (AEMTCA 2012), Pub. L. 112-210 (December 18, 2012)). Part C of Title III (42 U.S.C. Start Printed Page 707996311-6317), which was subsequently re-designated as Part A-1 for editorial reasons, established an energy conservation program for certain industrial equipment, including compressors, the subject of today's notice. (42 U.S.C. 6311(2)(B)(i)) Unlike some other types of equipment included in EPCA, the term “compressors” is undefined.

Section 341 of EPCA, 42 U.S.C. 6312, provides a general statement of purpose to improve the efficiency of a variety of industrial equipment to conserve the energy resources of the Nation and permits the Secretary of Energy to classify certain equipment as covered equipment if a determination is made by rulemaking that doing so is necessary to carry out the purposes of Part A-1 of EPCA. Consistent with this process, DOE is currently considering whether to regulate the efficiency of a specific group of compressors—commercial and industrial compressors. 77 FR 76972 (December 31, 2012). DOE received comments from interested parties, which are available in docket number EERE-2013-BT-STD-0040. The comments were considered in developing a Framework Document to explain the relevant issues, analyses, and processes it anticipates using when considering new energy conservation standards for commercial and industrial compressors. DOE issued that document and conducted a public meeting to discuss its contents earlier this year. 79 FR 6839 (February 5, 2014). For more information, see​buildings/​appliance_​standards/​rulemaking.aspx/​ruleid/​58.

Because the term “compressors” is undefined by EPCA, DOE considered a variety of definitions for this term to help ensure a reasonable level of clarity with respect to the type of equipment that might be regulated. In its ongoing proceeding, DOE offered for comment the following definition for “commercial and industrial compressors” to clarify the coverage of any potential test procedure or energy conservation standard:

Compressor: “A compressor is an electric-powered device that takes in air or gas at atmospheric pressure and delivers the air or gas at a higher pressure. Compressors typically have a specific ratio, the ratio of delivery pressure to supply pressure, greater than 1.20.”

After further evaluating this definition and considering the comments it received, DOE revisited this definition and offered a revised version. That version, which is based on International Organization for Standardization (ISO) Technical Report (TR) 12942, provides a different definition of the term “compressor” from DOE's initial approach. (ISO TR 12942 provides a means to classify modern compressor types along with definitions and related terms that can be utilized in technical and contractual specifications such as a manufacturer's literature and industrial statistics.) DOE offered the following revised definition for public comment:

Compressor: a machine or apparatus converting different types of energy into the potential energy of gas pressure for displacement and compression of gaseous media to any higher pressure values above atmospheric pressure with pressure-increase ratios exceeding 1.1.[1]

DOE is continuing to consider revisions to this definition, however, due at least in part to submitted comments in which some parties commented that the specified ratio should be different to avoid overlapping with what the compressor industry generally treats as “blowers,” equipment for which DOE may also establish standards. See 78 FR 7306 (February 1, 2013) (announcing DOE's issuance of a framework document related to the potential setting of energy conservation standards for industrial fans and blowers). Also see​buildings/​appliance_​standards/​rulemaking.aspx/​ruleid/​25.

While DOE's focus has centered primarily on those compressors that are intended to compress air, compressors are used in a wide variety of applications and may be used to compress different types of gases. DOE is aware that compressors intended to compress other gases such as natural gas (i.e., gas compressors) may, both collectively and individually, use a substantial amount of energy, as such compressors are often very large. An important application of gas compressors is the pipeline transport of natural gas. The drivers for such compressors can be natural gas turbines (particularly since gas is an easily accessible fuel out in the field), steam turbines, internal combustion engines, or electric motors. Recent data provided by the Energy Information Administration (EIA) indicate that the annual amount of natural gas used to transport natural gas through the pipeline system was about 0.7 quadrillion Btu. In addition to the pipeline transport of natural gas, compressors are used in the production and processing of natural gas, which is accounted for in the 1.4 quadrillion Btus of natural gas reported by EIA as “lease and plant fuel.” [2] As such, DOE is now considering the possibility of setting energy efficiency standards for natural gas compressors, in addition to efficiency standards for commercial and industrial air compressors.

To inform its decision making regarding natural gas compressors DOE will hold a public meeting to discuss and receive further comments and supporting data about the characteristics and energy use of this equipment as described in the RFI. (79 FR 45377)
