42 USC § 17191 - Definitions | Title 42 - The Public Health and Welfare | U.S. Code

USCPrelim is a preliminary release and may be subject to further revision before it is released again as a final version.

Current through Pub. L. 113-9. (See Public Laws for the current Congress.)

For purposes of this part:

(1) Engineered

When referring to enhanced geothermal systems, the term “engineered” means subjected to intervention, including intervention to address one or more of the following issues:

(A) Lack of effective permeability or porosity or open fracture connectivity within the reservoir.

(B) Insufficient contained geofluid in the reservoir.

(C) A low average geothermal gradient, which necessitates deeper drilling.

(2) Enhanced geothermal systems

The term “enhanced geothermal systems” means geothermal reservoir systems that are engineered, as opposed to occurring naturally.

(3) Geofluid

The term “geofluid” means any fluid used to extract thermal energy from the Earth which is transported to the surface for direct use or electric power generation, except that such term shall not include oil or natural gas.

(4) Geopressured resources

The term “geopressured resources” mean geothermal deposits found in sedimentary rocks under higher than normal pressure and saturated with gas or methane.

(5) Geothermal

The term “geothermal” refers to heat energy stored in the Earth’s crust that can be accessed for direct use or electric power generation.

(6) Hydrothermal

The term “hydrothermal” refers to naturally occurring subsurface reservoirs of hot water or steam.

(7) Systems approach

The term “systems approach” means an approach to solving problems or designing systems that attempts to optimize the performance of the overall system, rather than a particular component of the system.

Short Title

This part known as the “Advanced Geothermal Energy Research and Development Act of 2007”, see Short Title note set out under section 17001 of this title.

The table below lists the classification updates, since Jan. 3, 2012, for this section. Updates to a broader range of sections may be found at the update page for containing chapter, title, etc.

The most recent Classification Table update that we have noticed was Wednesday, May 29, 2013

An empty table indicates that we see no relevant changes listed in the classification tables. If you suspect that our system may be missing something, please double-check with the Office of the Law Revision Counsel.

How To Use

Multiple entries for a section are listed most recent first, within the section.

The Session Year indicates which session of Congress was responsible for the changes classified. The Congress number forms the first part of the Public Law number; each Congress has two sessions.

Abbreviations used in the Description of Change column:

An empty field implies a standard amendment.
"new" means a new section or new note, or all new text of an existing section or note.
"nt" means note.
"nt [tbl]" means note [table].
"prec" means preceding.
"fr" means a transfer from another section.
"to" means a transfer to another section.
"omitted" means the section is omitted.
"repealed" means the section is repealed.
"nt ed change" and "ed change" - See the Editorial Classification Change Table [pdf].

The Public Law field is linked to the development of the law in the Thomas system at the Library of Congress.

The Statutes at Large field is linked to the text of the law, in the context of its volume of the Statutes at Large, at the Government Printing Office. Please note that it takes a while for these pages to get posted, so for very recent legislation, you need to look at the "enrolled" version at the Thomas site.

The Statutes at Large references have been rendered in the format used as page numbers in the Public Law web pages to which we link, to facilitate copy-paste into browser "find on this (web) page" tools. We are still working on a more direct link facility.

For serious comparison work, we suggest copying all or a portion of the Public Law text into your favorite text editor, for convenient content traversal and window control.

Sections with change type "new" are a special case, still under development. All are now listed, at the title level only.

You will find that occassionally a specific update you notice in a Public Law listed in a classification table will already have made it into the Code. We assume this is an artifact of the LRC edit process. The LII does not edit the LRC content.

General Reference

Refer to the LRC (Law Revision Council) for explanations about the US Code from the folks who put it all together.

You can look for information about what it is and is not, which titles are positive law, the schedule of Supplements, etc. Under download you can find the source data we use here (GPO locator files), as well as, PDF files that look just like the paper books (these may be rather large).

Refer to the Thomas site for changes that have not yet made it into the classification tables.
