69-691: John J. Keetch , a fire researcher in the southeast, wrote that "One of the prime objectives of the National Fire Danger Rating System (NFDRS) is to provide as accurate a measure as possible of the relative seriousness of burning conditions and thereby, NFDRS can serve as an aid to fire control programs." In 1954 there were eight different fire danger rating systems in use across the United States. Better communication and better transportation were beginning to make mutual assistance agreements between fire control agencies more practical than in

138-410: A metonym for the federal government. The United States government is based on the principles of federalism and republicanism , in which power is shared between the federal government and state governments . The interpretation and execution of these principles, including what powers the federal government should have and how those powers can be exercised, have been debated ever since the adoption of

207-707: A complex set of relationships between state and federal courts. Federal courts can sometimes hear cases arising under state law pursuant to diversity jurisdiction , state courts can decide certain matters involving federal law, and a handful of federal claims are primarily reserved by federal statute to the state courts. Both court systems have exclusive jurisdiction in some areas and concurrent jurisdiction in others. The U.S. Constitution safeguards judicial independence by providing that federal judges shall hold office "during good behavior"; in practice, this usually means they serve until they die, retire, or resign. A judge who commits an offense while in office may be impeached in

276-490: A composite fuel moisture value as it reflects the contribution that all live and dead fuels have to potential fire intensity. The ERC is a cumulative or "build-up" type of index. As live fuels cure and dead fuels dry, the ERC values get higher, thus providing a good reflection of drought conditions. The scale is open-ended or unlimited and, as with other NFDRS components, is relative. Conditions producing an ERC value of 24 represent

345-607: A few cases. The judicial power extends to cases arising under the Constitution, an Act of Congress ; a U.S. treaty ; cases affecting ambassadors , ministers and consuls of foreign countries in the U.S.; cases and controversies to which the federal government is a party; controversies between states (or their citizens) and foreign nations (or their citizens or subjects); and bankruptcy cases (collectively "federal-question jurisdiction"). The Eleventh Amendment removed from federal jurisdiction cases in which citizens of one state were

414-418: A low resolution. NFDRS recognizes four types of fire: NFDRS is a complex set of equations with user-defined constants and measured variables to calculate the daily index and components that can be used for decision support. A Fire Danger Rating level takes into account current and antecedent weather, fuel types, and live and dead fuel moisture. The bottom line of the National Fire Danger Rating System in

483-405: A management action that addresses the dispatch of suppression resources that constitutes an appropriate level of response. Staffing levels, or adjective class ratings, are ways of linking fire danger information to fire management decisions. The designations for the various class or staffing levels are numerical (I to IV), or adjective (Low to Extreme). The first step in establishing staffing levels

552-470: A single elected term." Under the Presentment Clause of Article I, a bill that passes both chambers of Congress shall be presented to the president, who may sign the bill into law or veto the bill by returning it to the chamber where it originated. If the president neither signs nor vetoes a bill "within ten Days (Sundays excepted) after it shall have been presented to him" it becomes a law without

621-608: A special election can take place. The House and Senate each have particular exclusive powers. For example, the Senate must approve (give " advice and consent " to) many important presidential appointments, including cabinet officers, federal judges (including nominees to the Supreme Court), department secretaries (heads of federal executive branch departments), U.S. military and naval officers, and ambassadors to foreign countries. All legislative bills for raising revenue must originate in

690-506: A trade embargo, declare war upon a foreign government that the President had recognized, or decline to appropriate funds for an embassy in that country." The president may also negotiate and sign treaties, but ratifying treaties requires the consent of two-thirds of the Senate. Article II's Appointments Clause provides that the president "shall nominate, and by and with the Advice and Consent of

759-424: Is a number related to the available energy ( BTU ) per unit area (square foot) within the flaming front at the head of a fire. Daily variations in ERC are due to changes in moisture content of the various fuels present, both live and dead. Since this number represents the potential "heat release" per unit area in the flaming zone, it can provide guidance to several important fire activities. It may also be considered

Under the Reception Clause , the president is empowered to "receive Ambassadors and other public Ministers"; the president has broad authority to conduct foreign relations, is generally considered to have the sole power of diplomatic recognition , and is the United States' chief diplomat, although the Congress also has an important role in legislating on foreign affairs, and can, for example, "institute

1104-582: Is the selection by the state or federal land management agency of an NFDRS component or index that best describes the total fire problems in their protection area. Both state and federal land management agencies in Washington use the Energy Release Component (ERC) to determine staffing levels or adjective class ratings for the general public. From statistical analysis of historical fire weather data, agencies were able to determine various percentiles in

The U.S. federal government is composed of three distinct branches: legislative , executive , and judicial , whose powers are vested by the U.S. Constitution in the Congress , the president , and the federal courts , respectively. The powers and duties of these branches are further defined by acts of Congress, including

1587-577: The militia , exercise exclusive legislation in the District of Columbia , regulate interstate commerce , and to make laws necessary to properly execute powers. Over the two centuries since the United States was formed, many disputes have arisen over the limits on the powers of the federal government. These disputes have often been the subject of lawsuits that have ultimately been decided by the United States Supreme Court . Congressional oversight

One of the theoretical pillars of the U.S. Constitution is the idea of " checks and balances " among the powers and responsibilities of the three branches of American government: the executive, the legislative, and

1863-502: The Congress. The United States Congress , under Article I of the Constitution, is the legislative branch of the federal government. It is bicameral , comprising the House of Representatives and the Senate . The U.S. House of Representatives is made up of 435 voting members, each of whom represents a congressional district in a state from where they were elected. Apportionment of seats among

Prakash write of the Clause: "the President may neither breach federal law nor order their subordinates to do so, for defiance cannot be considered faithful execution. The Constitution also incorporates the English bars on dispensing or suspending the law, with some supposing that the Clause itself prohibits both." Many presidential actions are undertaken via executive orders , presidential proclamations , and presidential memoranda . The president

In addition, each house may name special, or select, committees to study specific problems. Today, much of the congressional workload is borne by the subcommittees, of which there are around 150. The Constitution grants numerous powers to Congress. Enumerated in Article I, Section 8, these include

2277-425: The House of Representatives. The approval of both chambers is required to pass all legislation, which then may only become law by being signed by the president (or, if the president vetoes the bill, both houses of Congress then re-pass the bill, but by a two-thirds majority of each chamber, in which case the bill becomes law without the president's signature). The powers of Congress are limited to those enumerated in

2346-464: The House plus its two senators). The District of Columbia has a number of electoral votes "equal to the whole number of Senators and Representatives in Congress to which the District would be entitled if it were a State, but in no event more than the least populous State". A President may also be seated by succession . As originally drafted, there was no limit to the time a President could serve, however

These appointments delegate "by legal authority a portion of

2553-483: The Twenty-second Amendment, ratified in 1951, originally limits any president to serving two four-year terms (8 years); the amendment specifically "caps the service of a president at 10 years" by providing that "if a person succeeds to the office of president without election and serves less than two years, he may run for two full terms; otherwise, a person succeeding to office of president can serve no more than

2622-404: The U.S. Constitution. In contrast, the Senate is made up of two senators from each state, regardless of population. There are currently 100 senators (2 from each of the 50 states), who each serve six-year terms. Approximately one-third of the Senate stands for election every two years. If a vacancy occurs, the state governor appoints a replacement to complete the term or to hold the office until

2760-433: The basic structure for a four-phase rating system had been outlined and the fire phase (spread phase) was ready for field testing. However, since the remaining phases of the rating system – ignition, risk, and fuel energy – were not available, a number of fire control agencies preferred to remain with the systems then in use. Adaptations, interpretations, and additions to the spread phase quickly followed, making it obvious that

2829-402: The case from state court to federal court. The United States Courts of Appeals are appellate courts that hear appeals of cases decided by the district courts, and some direct appeals from administrative agencies, and some interlocutory appeals. The U.S. Supreme Court hears appeals from the decisions of the courts of appeals or state supreme courts, and in addition has original jurisdiction over

2898-404: The chambers to consider urgent matters. The vice president is the second-highest official in rank of the federal government. The vice president's duties and powers are established in the legislative branch of the federal government under Article 1, Section 3, Clauses 4 and 5 as the president of the Senate ; this means that they are the designated presiding officer of the Senate. In that capacity,

2967-565: The country at stations from Maine to California and from Florida to Alaska. The system then became operational nationwide in 1972. When work started in 1968 on the NFDRS a framework was constructed. A philosophy had to be adopted in order to allow the development of the system to proceed. NFDRS provides a uniform consistent system that possesses standards which agencies with wildfire suppression responsibility can apply and interpret. NFDRS characterizes expected burning conditions for areas of 10,000 to 100,000 ac (4000 to 40,000 ha). The system has

3036-440: The creation of executive departments and courts subordinate to the U.S. Supreme Court . In the federal division of power, the federal government shares sovereignty with each of the 50 states in their respective territories. U.S. law recognizes Indigenous tribes as possessing sovereign powers , while being subject to federal jurisdiction. The full name of the republic is the "United States of America". No other name appears in

3105-581: The day-to-day operation of a fire prevention and suppression program is the staffing class . The staffing class is sometimes referred to as the action class, adjective class, precaution class, preparedness class, or the Industrial Fire Precaution Level (IFPL). The assumption behind staffing levels is that the continuum of fire danger can be divided into discrete intervals to which preplanned management actions are keyed. In other words, for each staffing level or adjective class, there should be

3174-512: The development of a complete, comprehensive, National Fire Danger Rating System. A target date of 1972 was established for getting a complete system ready for operational use. In 1970, a preliminary version of the system was tested at field sites in Arizona and New Mexico. In 1971, an improved version of the system was used operationally in the Southwest. Field trials were also conducted elsewhere across

3243-399: The distribution of historical ERC data that serve as breakpoints for various fire management decisions. Land management agencies in Washington use the 90th and 97th percentile of the ERC as a basis for determining staffing levels. In Western Washington, the 90th and 97th percentiles in the ERC frequency distribution are 44 BTUs per square foot and 55 BTUs per square foot. The output section of

3312-418: The executive branch when becoming president upon the death, resignation, or removal of the president, which has happened nine times in U.S. history. Lastly, in the case of a Twenty-fifth Amendment succession event, the vice president would become acting president, assuming all of the powers and duties of president, except being designated as president. Accordingly, by circumstances, the Constitution designates

3381-483: The judiciary. For example, while the legislative branch ( Congress ) has the power to create law, the executive branch under the president can veto any legislation—an act which, in turn, can be overridden by Congress. The president nominates judges to the nation's highest judiciary authority, the Supreme Court (as well as to lower federal courts), but those nominees must be approved by Congress. The Supreme Court, in turn, can invalidate unconstitutional laws passed by

3450-477: The law and creating precedent for future law and decisions. The United States Constitution does not specifically mention the power of judicial review , which is the power to declare a law unconstitutional. There have been instances in the past where such declarations have been ignored by the other two branches. Below the U.S. Supreme Court are the United States Courts of Appeals , and below them in turn are

3519-696: The office of vice president. Article II, Section 2 of the Constitution sets forth the creation of a presidential Cabinet. The role of the Cabinet is to advise the president and carry out the programs and laws of the federal government. The Cabinet is composed of the vice president and the leaders of 15 executive departments. Those executive departments are the Departments of State, Treasury, Defense, Justice, Interior, Agriculture, Commerce, Labor, Health and Human Services, Housing and Urban Development, Transportation, Energy, Education, Veterans Affairs, and Homeland Security. Additionally, there are seven other members of

3588-443: The past. State compacts, and in the case of the federal government , interagency and interregional agreements were bringing fire control teams together from widely separated areas of the county. It became necessary to establish a national system for estimating Fire danger and fire behavior to improve and simplify communications among all people concerned with wildland fire . Work on a national rating system began in 1959. By 1961,

3657-480: The plaintiffs and the government of another state was the defendant. It did not disturb federal jurisdiction in cases in which a state government is a plaintiff and a citizen of another state the defendant. The power of the federal courts extends both to civil actions for damages and other redress, and to criminal cases arising under federal law. The interplay of the Supremacy Clause and Article III has resulted in

3726-497: The power to adjourn Congress whenever the House and Senate cannot agree when to adjourn; no president has ever used this power. The president also has the constitutional power to, "on extraordinary Occasions, convene both Houses, or either of them"; this power has been used "to consider nominations, war, and emergency legislation." This Section invests the President with the discretion to convene Congress on "extraordinary occasions"; this special session power that has been used to call

3795-471: The power to re-organize or even abolish federal courts lower than the Supreme Court. The U.S. Supreme Court decides cases and controversies , which include matters pertaining to the federal government, disputes between states, and interpretation of the United States Constitution, and, in general, can declare legislation or executive action made at any level of the government as unconstitutional , nullifying

3864-437: The power to remove the president, federal judges, and other federal officers from office. The House of Representatives and Senate have separate roles in this process. The House must first vote to impeach the official. Then, a trial is held in the Senate to decide whether the official should be removed from office. As of 2023 , three presidents have been impeached: Andrew Johnson , Bill Clinton , and Donald Trump (twice). None of

3933-420: The powers to levy and collect taxes ; to coin money and regulate its value; provide for punishment for counterfeiting; establish post offices and roads, issue patents, create federal courts inferior to the Supreme Court , combat piracies and felonies , declare war , raise and support armies , provide and maintain a navy , make rules for the regulation of land and naval forces, provide for, arm and discipline

4002-494: The president and approved with the "advice and consent" of the U.S. Senate. Once confirmed, these "Cabinet secretaries" serve at the pleasure of the president. In addition to the executive departments, a number of staff organizations are grouped into the Executive Office of the President (EOP), which was created in 1939 by President Franklin D. Roosevelt. The EOP is overseen by the White House Chief of Staff. The EOP includes

4071-476: The president and confirmed by the United States Senate. The Judiciary Act of 1789 subdivided the nation jurisdictionally into judicial districts and created federal courts for each district. The three tiered structure of this act established the basic structure of the national judiciary: the Supreme Court, 13 courts of appeals, 94 district courts, and two courts of special jurisdiction. Congress retains

4140-466: The president has major agenda-setting powers to influence lawmaking and policymaking, and typically has a major role as the leader of their political party . The president and vice president are normally elected as running mates by the Electoral College ; each state has a number of electoral votes equal to the size of its Congressional delegation ( i.e. , its number of Representatives in

4209-525: The president's signature, "unless the Congress by their Adjournment prevent its Return in which Case it shall not be a Law" (called a pocket veto ). A presidential veto may be overridden by a two-thirds vote in both houses of Congress; this occurs relatively infrequently. The president may be impeached by a majority in the House and removed from office by a two-thirds majority in the Senate for " treason , bribery , or other high crimes and misdemeanors ". The president may not dissolve Congress , but has

4278-475: The same way as the president or other officials of the federal government. U.S. judges are appointed by the president, subject to confirmation by the Senate. Another Constitutional provision prohibits Congress from reducing the pay of any present Article III judge. However, Congress is able to set a lower salary for all future judges who take office after such a pay reduction is passed by Congress. Energy Release Component The energy release component (ERC)

4347-590: The sovereign powers of the federal government." The Constitution grants the president the "Power to grant Reprieves and Pardons for Offences against the United States , except in Cases of Impeachment"; this clemency power includes the power to issue absolute or conditional pardons, and to issue commute sentences , to remit fines, and to issue general amnesties . The presidential clemency power extends only to federal crimes, and not to state crimes. The president has informal powers beyond their formal powers. For example,

4416-460: The spread phase was not uniformly applicable across the country. More research followed and in 1965 a research project headquartered in Seattle was established to provide a fresh look at the needs and requirements for a national, fire danger, rating system. After canvassing many fire control agencies across the country, the Seattle research group recommended new directions for research that would lead to

4485-512: The term "U.S. Government" is sometimes used. The terms "Federal" and "National" in government agency or program names generally indicate affiliation with the federal government; for instance, the Federal Bureau of Investigation , National Oceanic and Atmospheric Administration , and National Park Service . Because the seat of government is in Washington, D.C. , "Washington" is sometimes used as

4554-434: The three were removed from office following trial in the Senate. Article I, Section 2, paragraph 2 of the U.S. Constitution gives each chamber the power to "determine the rules of its proceedings". From this provision were created congressional committees , which do the work of drafting legislation and conducting congressional investigations into national matters. The 118th Congress (2023–2025) has 20 standing committees in

4623-522: The trial courts wherein cases that are considered under the Judicial Code (Title 28, United States Code) consistent with the jurisdictional precepts of federal question jurisdiction , diversity jurisdiction, and pendent jurisdiction can be filed and decided. The district courts can also hear cases under removal jurisdiction , wherein a case brought in a state court meets the requirements for diversity jurisdiction, and one party litigant chooses to "remove"

4692-508: The vice president as routinely in the legislative branch, or succeeding to the executive branch as president, or possibly being in both as acting president pursuant to the Twenty-fifth Amendment . Because of circumstances, the overlapping nature of the duties and powers attributed to the office, the title of the office and other matters, such has generated a spirited scholarly dispute regarding attaching an exclusive branch designation to

4761-510: The vice president has the authority ( ex officio , for they are not an elected member of the Senate) to cast a tie-breaking vote . Pursuant to the Twelfth Amendment , the vice president presides over the joint session of Congress when it convenes to count the vote of the Electoral College . As first in the U.S. presidential line of succession , the vice president's duties and powers move to
