122-402: The refuge is home to various animals, including a herd of 150 elk , occasional black bear , mountain lions, and moose; as well as badgers, bats, coyote , two species of owl , mule deer , northern flicker , white pelican , black-tailed prairie dog , and porcupine . The site also contains an estimated 630 plant species. The Rocky Flats National Wildlife Refuge is one of over 560 refuges in

244-531: A misfolded protein known as a prion , affects the brain tissue in elk, and has been detected throughout their range in North America. First documented in the late 1960s in mule deer, the disease has affected elk on game farms and in the wild in a number of regions. Elk that have contracted the disease begin to show weight loss, changes in behavior, increased watering needs, excessive salivation and urinating and difficulty swallowing, and at an advanced stage,

366-675: A CERCLA report. Because the environmental investigation found levels of contamination in the Peripheral Operable Unit (now Refuge lands) were below levels of regulatory concern, the Refuge did not require remedial action. In May 2007, the POU was deleted from the Superfund National Priorities List. The lands comprising the POU were transferred to the U.S. Fish and Wildlife Service for establishment as

488-410: A Natural Resource Damage Assessment (NRDA). Natural resource trustees determine and quantify injuries caused to natural resources through either releases of hazardous substances or cleanup actions and then seek to restore ecosystem services to the public through conservation, restoration, and/or acquisition of equivalent habitat. Responsible parties are assessed damages for the cost of the assessment and

610-464: A Superfund site. In 1978, residents of the rural black community of Triana, Alabama were found to be contaminated with DDT and PCB , some of whom had the highest levels of DDT ever recorded in human history. The DDT was found in high levels in Indian Creek, which many residents relied on for sustenance fishing. Although this major health threat to residents of Triana was discovered in 1978,

732-539: A chemical or oil spill. From 2000 to 2015, Congress allocated about $ 1.26 billion of general revenue to the Superfund program each year. Consequently, less than half the number of sites were cleaned up from 2001 to 2008, compared to before. The decrease continued during the Obama administration , and since under the direction of EPA Administrator Gina McCarthy Superfund cleanups decreased even more from 20 in 2009 to

854-460: A contribution action under the CERCLA. CERCLA liability has generally been judicially established as joint and several among PRPs to the government for cleanup costs (i.e., each PRP is hypothetically responsible for all costs subject to contribution), but CERCLA liability is allocable among PRPs in contribution based on comparative fault. An "orphan share" is the share of costs at a Superfund site that

976-439: A day or two, and matings usually involve a dozen or more attempts. By the autumn of their second year, females can produce one and, very rarely, two offspring. Reproduction is most common when cows weigh at least 200 kilograms (440 lb). Dominant bulls follow groups of cows during the rut from August into early winter. A bull will defend his harem of 20 cows or more from competing bulls and predators. Bulls also dig holes in

1098-453: A disproportionate amount. The EPA seeks to identify parties responsible for hazardous substances released to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund (a trust fund) and seek to recover those costs from the responsible parties through settlements or other legal means. Approximately 70% of Superfund cleanup activities historically have been paid for by

1220-617: A distinct species, namely the Central Asian red deer ( Cervus hanglu ), which also includes the Kashmir stag . Elk have thick bodies with slender legs and short tails. They have a shoulder height of 0.75–1.5 m (2 ft 6 in – 4 ft 11 in) with a nose-to-tail length of 1.6–2.7 m (5 ft 3 in – 8 ft 10 in). Males are larger and weigh 178–497 kg (392–1,096 lb) while females weigh 171–292 kg (377–644 lb). The largest of

1342-515: A dozen subspecies. But mitochondrial DNA studies conducted in 2004 on hundreds of samples from red deer and elk subspecies and other species of the Cervus deer family, strongly indicate that elk, or wapiti, should be a distinct species, namely Cervus canadensis . DNA evidence validates that elk are more closely related to Thorold's deer and even sika deer than they are to the red deer. Elk and red deer produce fertile offspring in captivity, and

1464-484: A human getting variant Creutzfeldt–Jakob disease . Antlers are also used in artwork, furniture and other novelty items. All Asian subspecies, along with other deer, have been raised for their antlers in central and eastern Asia by Han Chinese , Turkic peoples , Tungusic peoples , Mongolians , and Koreans . Elk farms are relatively common in North America and New Zealand. Native Americans have used elk hides for tepee covering, clothing and footwear. Since 1967,

1586-401: A large animal, buglings can reach a frequency of 4000 Hz. This is achieved by blowing air from the glottis through the nasal cavities. Elk can produce deeper pitched (150 Hz) sounds using the larynx . Cows produce an alarm bark to alert other members of the herd to danger, while calves will produce a high-pitched scream when attacked. Female elk have a short estrus cycle of only

1708-477: A lesser chance of successful listing and cleanup than areas with higher income levels. After the executive order had been put in place, there persisted a discrepancy between the demographics of the communities living near toxic waste sites and their listing as Superfund sites, which would otherwise grant them federally funded cleanup projects. Communities with both increased minority and low-income populations were found to have lowered their chances of site listing after

1830-491: A mean weight of 275 kilograms (606 lb). The elk is the second largest extant species of deer, after the moose . Antlers are made of bone, which can grow at a rate of 2.5 centimeters (0.98 in) per day. While actively growing, a soft layer of highly vascularized skin known as velvet covers and protects them. This is shed in the summer when the antlers have fully developed. Bull elk typically have around six tines on each antler. The Siberian and North American elk carry

1952-488: A mere 8 in 2014. In November 2021, Congress reauthorized an excise tax on chemical manufacturers, under the Infrastructure Investment and Jobs Act . The new chemical excise tax is effective July 1, 2022, and is double the rate of the previous Superfund tax. The 2021 law also authorized $ 3.5 billion in emergency appropriations from the U.S. government general fund for hazardous site cleanups in

2074-419: A polluter could not be identified, could not or would not pay (bankruptcy or refusal), consisted of about $ 1.6 billion and then increased to $ 8.5 billion. Initially, the framework for implementing the program came from the oil and hazardous substances National Contingency Plan. The EPA published the first Hazard Ranking System in 1981, and the first National Priorities List in 1983. Implementation of

2196-412: A requirement by addressing low income populations and minority populations that have experienced disproportionate adverse health and environmental effects as a result of their programs, policies, and activities. The EPA regional offices had to apply required guidelines for its Superfund managers to take into consideration data analysis, managed public participation, and economic opportunity when considering

2318-528: A site for the NPL is intended primarily to guide the EPA in: Despite the name, the Superfund trust fund has lacked sufficient funds to clean up even a small number of the sites on the NPL. As a result, the EPA typically negotiates consent orders with PRPs to study sites and develop cleanup alternatives, subject to EPA oversight and approval of all such activities. The EPA then issues a Proposed Plans for remedial action for

2440-418: A site on which it takes public comment, after which it makes a cleanup decision in a Record of Decision (ROD). RODs are typically implemented under consent decrees by PRPs or under unilateral orders if consent cannot be reached. If a party fails to comply with such an order, it may be fined up to $ 37,500 for each day that non-compliance continues. A party that spends money to clean up a site may sue other PRPs in

2562-560: A state Superfund law and may perform NRDA either through state laws or through other federal authorities such as the Oil Pollution Act. CERCLA created the Agency for Toxic Substances and Disease Registry (ATSDR). The primary goal of a Superfund cleanup is to reduce the risks to human health through a combination of cleanup, engineered controls like caps and site restrictions such as groundwater use restrictions. A secondary goal

2684-435: A tendency to do most of their feeding in the mornings and evenings, seeking sheltered areas in between feedings to digest. Their diets vary somewhat depending on the season, with native grasses being a year-round supplement, tree bark being consumed in winter, and forbs and tree sprouts during the summer. Elk consume an average of 9.1 kilograms (20 lb) of vegetation daily. Particularly fond of aspen sprouts which rise in

2806-580: A wild population has not yet established. Since 2015, elk have also been reintroduced in a number of other states, including Missouri , and introduced to the islands of Etolin and Afognak in Alaska. Reintroduction of the elk into Ontario began in the early 20th century and is ongoing with limited success. Elk and red deer were introduced to Argentina in the early 20th century. There they are now considered an invasive species , encroaching on Argentinian ecosystems where they compete for food with

2928-570: A winter- or disease-weakened adult. In the Greater Yellowstone Ecosystem , which includes Yellowstone National Park, bears are the most significant predators of calves while healthy bulls have never been recorded to be killed by bears and such encounters can be fatal for bears. The killing of cows in their prime is more likely to affect population growth than the killing of bulls or calves. Elk may avoid predation by switching from grazing to browsing. Grazing puts an elk in

3050-639: Is a good source of iron , phosphorus and zinc . A male elk can produce 10 to 11 kilograms (22 to 24 lb) of antler velvet annually and on ranches in the United States, Canada and New Zealand, it is collected and sold to markets in East Asia , where it is used in medicine. Some cultures consider antler velvet to be an aphrodisiac . However, consuming velvet from elk in North America may be risky since velvet from animals infected with chronic wasting disease may contain prions that could result in

3172-492: Is a parasitic nematode known to affect the spinal cord and brain tissue of elk and other species, leading to death. The definitive host is the white-tailed deer, in which it normally has no ill effects. Snails and slugs, the intermediate hosts, can be inadvertently consumed by elk during grazing. The liver fluke Fascioloides magna and the nematode Dictyocaulus viviparus are also commonly found parasites that can be fatal to elk. Chronic wasting disease , transmitted by

3294-465: Is also not known, but it appears to be highly contagious among elk. Studies are being undertaken by government departments to determine how to halt or eliminate the disease. The elk ranges from central Asia through to Siberia and east Asia and in North America. They can be found in open deciduous woodlands, boreal forests, upland moors, mountainous areas and grasslands. The International Union for Conservation of Nature and Natural Resources (IUCN) list

3416-449: Is attributable to a PRP that is either unidentifiable or insolvent. The EPA tries to treat all PRPs equitably and fairly. Budgetary cuts and constraints can make more equitable treatment of PRPs more difficult. Upon notification of a potentially hazardous waste site, the EPA conducts a Preliminary Assessment/Site Inspection (PA/SI), which involves records reviews, interviews, visual inspections, and limited field sampling. Information from

3538-528: Is common with many deer species, and they lose their spots by the end of summer. After two weeks, calves are able to join the herd, and are fully weaned at two months of age. Elk calves are as large as an adult white-tailed deer by the time they are six months old. Elk will leave their natal (birth) ranges before they are three years old. Males disperse more often than females, as adult cows are more tolerant of female offspring from previous years. Elk live 20 years or more in captivity but average 10 to 13 years in

3660-411: Is often pointed to as the roots of the environmental justice movement. PCBs were illegally dumped into the community and then it eventually became a PCB landfill . Community leaders pressed the state for the site to be cleaned up for an entire decade until it was finally detoxified. However, this decontamination did not return the site to its pre-1982 conditions. There has been a call for reparations to

3782-740: Is presented in a Proposed Plan for public review and comment, followed by a selected alternative in a ROD. The site then enters into a Remedial Design phase and then the Remedial Action phase. Many sites include long-term monitoring. Once the Remedial Action has been completed, reviews are required every five years, whenever hazardous substances are left onsite above levels safe for unrestricted use. As of December 9, 2021 , there were 1,322 sites listed; an additional 447 had been delisted, and 51 new sites have been proposed. Historically about 70 percent of Superfund cleanup activities have been paid for by potentially responsible party (PRPs). When

3904-440: Is seen in other artiodactyl species, like the bighorn sheep , pronghorn and the white-tailed deer , to varying degrees. Elk dwell in open forest and forest-edge habitats, grazing on grasses and sedges and browsing higher-growing plants, leaves, twigs and bark. Male elk have large, blood- and nerve-filled antlers , which they routinely shed each year as weather warms-up. Males also engage in ritualized mating behaviors during

4026-657: Is the Church Rock uranium mill spill on the Navajo Nation. It was the largest radioactive spill in the US but received a long delay in government response and cleanup after being placed as a lower priority site. Two sets of five-year cleanup plans have been put in place by US Congress, but contamination from the Church Rock incident has still not been completely cleaned up. Today, uranium contamination from mining during

4148-482: Is the official state animal for Utah . An image of an elk and a moose appear on the state seal and flag of Michigan. The Benevolent and Protective Order of Elks (B.P.O.E.) chose the elk as its namesake because a number of its attributes seemed appropriate for cultivation by members of the fraternity. Jewel-encrusted, gold-mounted elk teeth are prized possessions of many members of the B.P.O.E. Although breakdown figures for each game species are not available in

4270-554: Is to return the site to productive use as a business, recreation or as a natural ecosystem. Identifying the intended reuse early in the cleanup often results in faster and less expensive cleanups. EPA's Superfund Redevelopment Program provides tools and support for site redevelopment. CERCLA was enacted by Congress in 1980 in response to the threat of hazardous waste sites, typified by the Love Canal disaster in New York , and

4392-667: Is typically characterized by a diverse community of bacteria specialized in breaking down complex plant fibers and cellulose , whereas the supplementally fed gut microbiome may have less fiber-digesting bacteria. Therefore, transitioning from natural foraging to concentrated alfalfa pellets can cause changes in the gut microbiome that might affect the elk's ability to efficiently digest their natural diet or could potentially lead to imbalances that affect overall health. Predators of elk include wolves , coyotes , brown and black bears , cougars , and Siberian tigers . Coyote packs mostly prey on elk calves, though they can sometimes take

4514-661: The Oxford English Dictionary , the etymology of the word "elk" is "of obscure history". In Classical Antiquity , the European Alces alces was known as Ancient Greek : ἄλκη , romanized :  álkē and Latin : alces , words probably borrowed from a Germanic language or another language of northern Europe. By the 8th century, during the Early Middle Ages , the moose was known as Old English : elch, elh, eolh, derived from

4636-618: The Boy Scouts of America have assisted employees at the National Elk Refuge in Wyoming by collecting the antlers which are shed each winter. They are then auctioned, with 80% of the proceeds returned to the refuge. In 2010, 2,520 kilograms (5,560 lb) of antlers were auctioned, which brought in over $ 46,000. Superfund Superfund is a United States federal environmental remediation program established by

4758-625: The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ( CERCLA ). The program is administered by the Environmental Protection Agency (EPA). The program is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as Superfund sites . Of all the sites selected for possible action under this program (and there are tens of thousands across

4880-611: The Fiordland National Park . In 1949 the New Zealand American Fiordland Expedition was undertaken to study the descendants of this release. There is significant hybridization of elk with red deer. These deer have had an adverse impact on forest regeneration of some plant species, as they consume more palatable species, which are replaced with those that are less favored by the elk. The long-term impact will be an alteration of

5002-706: The Hazard Ranking System (HRS) to calculate a site score (ranging from 0 to 100) based on the actual or potential release of hazardous substances from a site. A score of 28.5 places a site on the National Priorities List, eligible for long-term, remedial action (i.e., cleanup) under the Superfund program. As of March 23, 2022 , there were 1,333 sites listed; an additional 448 had been delisted, and 43 new sites have been proposed. Superfund also authorizes natural resource trustees, which may be federal, state, and/or tribal, to perform

5124-694: The Korean Peninsula and Siberia are the Manchurian wapiti ( C. c. xanthopygus ) and the Alashan wapiti ( C. c. alashanicus ). The Manchurian subspecies is darker, and more reddish, in coloration than other populations. The Alashan wapiti of northern Central China is the smallest of all the subspecies, has the lightest coloration, and is one of the least-studied. Recent DNA analyses suggest that there are no more than three or four total subspecies of elk. All American forms, aside from possibly

5246-641: The Late Pleistocene , surviving into the early Holocene in Southern Sweden and the Alps . The now-extinct North American Merriam's elk subspecies ( Cervus canadensis merriami ) once ranged south into Mexico . The wapiti has also successfully adapted to countries outside of its natural range where it has been introduced, including Argentina and New Zealand ; the animal's adaptability in these areas may, in fact, be so successful as to threaten

5368-475: The National Elk Refuge , having migrated south from the southern portions of Yellowstone National Park and west from the Shoshone and Bridger–Teton National Forests . Elk are ruminants and therefore have four-chambered stomachs. Unlike white-tailed deer and moose, which are chiefly browsers, elk are similar to cattle in that they are primarily grazers . But like other deer, they also browse . Elk have

5490-914: The Proto-Germanic : *elho- , *elhon- and possibly connected with the Old Norse : elgr . Later, the species became known in Middle English as elk , elcke , or elke , appearing in the Latinized form alke , with the spelling alce borrowed directly from Latin: alces . Noting that elk "is not the normal phonetic representative" of the Old English elch , the Oxford English Dictionary derives elk from Middle High German : elch , itself from Old High German : elaho . The American Cervus canadensis

5612-751: The Roosevelt ( C. canadensis roosevelti ), Tule ( C. c. nannodes ), Manitoban ( C. c. manitobensis ) and Rocky Mountain elk ( C. c. nelsoni ). The eastern elk ( C. c. canadensis ) and Merriam's elk ( C. c. merriami ) subspecies have been extinct for at least a century. Four subspecies described from the Asian continent include the Altai wapiti ( C. c. sibiricus ) and the Tianshan wapiti ( C. c. songaricus ). Two distinct subspecies found in China, Mongolia ,

5734-578: The Valley of the Drums in Kentucky . It was recognized that funding would be difficult, since the responsible parties were not easily found, and so the Superfund was established to provide funding through a taxing mechanism on certain industries and to create a comprehensive liability framework to be able to hold a broader range of parties responsible. The initial Superfund trust fund to clean up sites where

5856-497: The mating season , including posturing to attract females, antler-wrestling (sparring), and bugling , a loud series of throaty whistles, bellows, screams, and other vocalizations that establish dominance over other males and aim to attract females. Elk were long believed to belong to a subspecies of the European red deer ( Cervus elaphus ), but evidence from many mitochondrial DNA genetic studies, beginning in 1998, shows that

5978-471: The 2006 National Survey from the U.S. Fish and Wildlife Service, hunting of wild elk is most likely the primary economic impact. While elk are not generally harvested for meat production on a large scale, some restaurants offer the meat as a specialty item and it is also available in some grocery stores. The meat has a taste somewhere between beef and venison and is higher in protein and lower in fat and cholesterol than beef, pork, and chicken. Elk meat

6100-550: The 600 acres that contain the former weapons site and monitoring areas. These remain under the jurisdiction of the DOE and will not be opened to the public. While some greet the new park with enthusiasm, others question assessments of its safety. Federal lawsuits have been filed against the United States Fish and Wildlife Service and others in an attempt to block opening of the park. The U.S. Fish and Wildlife Service opened

6222-591: The Cold War era remains throughout the Navajo Nation, posing health risks to the Navajo community. The data in the Superfund Program are available to the public. While the simple and relatively easy sites have been cleaned up, EPA is now addressing a residual number of difficult and massive sites such as large-area mining and sediment sites, which is tying up a significant amount of funding. Also, while

6344-468: The European variety of the moose , Alces alces , but was transferred to Cervus canadensis by North American colonists. The name "wapiti" is derived from a Shawnee and Cree word meaning "white rump", after the distinctive light fur around the tail region which the animals may fluff-up or raise to signal their agitation or distress to one another, when fleeing perceived threats, or among males courting females and sparring for dominance. A similar trait

6466-613: The National Wildlife Refuge System – a network of lands set aside and managed by the U.S. Fish and Wildlife Service specifically for wildlife. The Refuge is located along the Front Range of Colorado at the intersection of Jefferson, Boulder, and Broomfield counties. The U.S. Fish and Wildlife Service manages the Refuge. Native Americans occupied the land intermittently prior to the 1800s and limited artifacts have been located from this era. Starting in 1868,

6588-528: The PA/SI is used by the EPA to develop a Hazard Ranking System (HRS) score to determine the CERCLA status of the site. Sites that score high enough to be listed typically proceed to a Remedial Investigation/Feasibility Study (RI/FS). The RI includes an extensive sampling program and risk assessment that defines the nature and extent of the site contamination and risks. The FS is used to develop and evaluate various remediation alternatives. The preferred alternative

6710-633: The Rocky Flats National Wildlife Refuge Act of 2001 ( Pub. L.   107–107 (text) (PDF) , 115  Stat.   1379 , enacted December 28, 2001 ), most of the 6,240-acre (25.3 km) Rocky Flats site became a refuge, provided that certification from the United States Environmental Protection Agency (EPA) is obtained and which asserts that the cleanup and closure have been completed. The refuge does not include

6832-558: The Rocky Flats National Wildlife Refuge, pursuant to an Act of Congress. Despite the investigation and cleanup efforts, some question the adequacy of cleanup efforts and agency studies. In 2017, local activists sued the U.S. Fish and Wildlife Service. On September 29, 2017, the U.S. District Court dismissed this lawsuit. The Court explained the activist groups "merely rehashed old arguments," and did not provide new evidence or legal authority as support for

6954-599: The Rocky Flats mission was terminated when President George H. W. Bush canceled the W-88 Trident Warhead program. Nuclear and nonnuclear production stopped in 1993, and in 1994 the last shipment of defense-related materials was sent off-site. The plant was subject to a $ 7 billion Superfund investigation and environmental cleanup effort. The site was added to the U.S. Environmental Protection Agency’s (EPA) National Priorities List (Superfund List) in 1989. It

7076-674: The Scott family established a homestead here and the land was used to raise cattle. Later, the Lindsay family raised cattle and built a house and barn in the 1940s. In 1951, the U.S. Atomic Energy Commission acquired 2,519 acres, which included the Lindsay property, for the Rocky Flats Plant to produce nuclear and nonnuclear weapons including plutonium fission primaries for nuclear weapons. An additional 4,027 acres were acquired in 1974 for plant expansion. This 6,500-acre Rocky Flats Site

7198-481: The Superfund program, the EPA and state agencies use the HRS to calculate a site score (ranging from 0 to 100) based on the actual or potential release of hazardous substances from a site through air , surface water or groundwater . A score of 28.5 places the site on the National Priorities List, making the site eligible for long-term remedial action (i.e., cleanup) under the Superfund program. Federal actions to address

In domesticated cattle, brucellosis causes infertility, abortions, and reduced milk production. It is transmitted to humans as undulant fever , producing influenza -like symptoms that may last for years. Though bison are more likely to transmit the disease to other animals, elk inadvertently transmitted brucellosis to horses in Wyoming and cattle in Idaho . Researchers are attempting to eradicate

Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups). The state of New Jersey , the fifth smallest state in the U.S., is the location of about ten percent of the priority Superfund sites,

7686-557: The US. Elk were reintroduced in Michigan in 1918 after going extinct there in 1875. The Rocky Mountain elk subspecies was reintroduced by hunter-conservation organizations into the Appalachian region of the U.S. where the now extinct eastern elk once lived. They were reintroduced to Pennsylvania beginning in 1913 and throughout the mid-20th Century, and now remain at a stable population of approximately 1,400 individuals. Since

7808-432: The big bull to avoid harassment. Dominant bulls are intolerant of spike bulls and will chase them away from their harems. The gestation period is eight to nine months and the offspring weigh around 16 kilograms (35 lb). When the females are near to giving birth, they tend to isolate themselves from the main herd, and will remain isolated until the calf is large enough to escape predators. Calves are born spotted, as

7930-406: The bull will copiously lick the female and then mount her. Younger, less dominant bulls, known as "spike bulls" because their antlers have not yet forked, will harass unguarded cows. These bulls are impatient and will not perform any courtship rituals and will continue to pursue a female even when she signals him to stop. As such, they are less reproductively successful, and a cow may stay close to

8052-556: The burden of the cost was shifted to taxpayers in the general public. Since 2001, most of the cleanup of hazardous waste sites has been funded through taxpayers generally. Despite its name, the program suffered from under-funding, and by 2014 Superfund NPL cleanups had decreased to only 8 sites, out of over 1,200. In November 2021, the Infrastructure Investment and Jobs Act reauthorized an excise tax on chemical manufacturers, for ten years starting in July 2022. The EPA and state agencies use

8174-480: The cleanup is functioning as designed. These lands are not part of the Refuge. The Rocky Flats National Wildlife Refuge consists of lands that were the former Rocky Flats Plant security buffer zone. The Superfund investigation and cleanup effort found that Refuge lands (then-called the Peripheral Operable Unit) would be suitable for unlimited use and unrestricted exposure - that is, any use. Under

However, it was not until 2004 when the EPA completed the clean-up efforts and eliminated the lead pollutant sources from the site. The Afton community of Warren County, North Carolina is one of the most prominent environmental injustice cases and

8418-644: The community which has not yet been met. Bayview-Hunters Point, San Francisco , a historically African American community, has faced persistent environmental discrimination due to the poor remediation efforts of the San Francisco Naval Shipyard , a federally declared Superfund site. The negligence of multiple agencies to adequately clean this site has led Bayview residents to be subject to high rates of pollution and has been tied to high rates of cancer, asthma, and overall higher health hazards than other regions of San Francisco. One example

8540-808: The compromising situation of being in an open area with its head down, leaving it unable to see what is going on in the surrounding area. Living in groups also lessens the risk of an individual falling to predation. Large bull elk are less vulnerable and can afford to wander alone, while cows stay in larger groups for protection for their calves. Bulls are more vulnerable to predation by wolves in late winter, after they have been weakened by months of chasing females and fighting. Males that have recently lost their antlers are more likely to be preyed upon. At least 53 species of protist and animal parasites have been identified in elk. Most of these parasites seldom lead to significant mortality among wild or captive elk. Parelaphostrongylus tenuis (brainworm or meningeal worm)

8662-484: The disease leads to death. No risks to humans have been documented, nor has the disease been demonstrated to pose a threat to domesticated cattle. In 2002, South Korea banned the importation of elk antler velvet due to concerns about chronic wasting disease. The Gram-negative bacterial disease brucellosis occasionally affects elk in the Greater Yellowstone Ecosystem, the only place in

8784-557: The disease through vaccinations and herd-management measures, which are expected to be successful. Nevertheless, research has been ongoing since 2002, and a successful vaccine has yet to be developed as of 2016 . A recent necropsy study of captive elk in Pennsylvania attributed the cause of death in 33 of 65 cases to either gastrointestinal parasites (21 cases, primarily Eimeria sp. and Ostertagia sp.) or bacterial infections (12 cases, mostly pneumonia ). Elk hoof disease

8906-427: The disproportionate health and environmental disparities that minority and low-income populations face through Executive Order 12898 required federal agencies to make environmental justice central to their programs and policies. Superfund sites have been shown to impact minority communities the most. Despite legislation specifically designed to ensure equity in Superfund listing, marginalized populations still experience

9028-478: The early Holocene of central Alaska, where it was the main hunted animal along with bison , and survived in Yukon until around 1400 BP (550 AD). As of 2014, population figures for all North American elk subspecies were around one million. Prior to the European colonization of North America, there were an estimated 10 million on the continent. There are many past and ongoing examples of reintroduction into areas of

9150-640: The elk) first appear in the fossil record 25 million years ago, during the Oligocene in Eurasia , but do not appear in the North American fossil record until the early Miocene . The extinct Irish elk ( Megaloceros ) was not a member of the genus Cervus but rather the largest member of the wider deer family (Cervidae) known from the fossil record. Until recently, red deer and elk were considered to be one species, Cervus elaphus , with over

9272-521: The end of FY 2003. Since that time Superfund sites for which the PRPs could not pay have been paid for from the general fund. Under the 2021 authorization by Congress, collection of excise taxes from chemical manufacturers will resume in 2022. The Hazard Ranking System is a scoring system used to evaluate potential relative risks to public health and the environment from releases or threatened releases of hazardous wastes at uncontrolled waste sites. Under

9394-401: The executive order, while on the other hand, increases in income led to greater chances of site listing. Of the populations living within 1 mile radius of a Superfund site, 44% of those are minorities despite only being around 37% of the nation's population. As of January 2021, more than 9,000 federally subsidized properties, including ones with hundreds of dwellings, were less than a mile from

9516-456: The federal government did not act until 5 years later after the mayor of Triana filed a class-action lawsuit in 1980. In West Dallas, Texas , a mostly African American and Latino community, a lead smelter poisoned the surrounding neighborhood, elementary school, and day cares for more than five decades. Dallas city officials were informed in 1972 that children in the proximity of the smelter were being exposed to lead contamination. The city sued

9638-419: The forest-adapted European red deer . Elk are among the most gregarious deer species. During the summer group size can reach 400 individuals. For most of the year, adult males and females are segregated into different herds. Female herds are larger while bulls form small groups and may even travel alone. Young bulls may associate with older bulls or female groups. Male and female herds come together during

9760-510: The geography of toxic waste site remediation. Some environmentalists and industry lobbyists saw the Clinton administration's environmental justice policy as an improvement, but the order did not receive bipartisan support. The newly elected Republican Congress made numerous unsuccessful efforts to significantly weaken the program. The Clinton administration then adopted some industry favored reforms as policy and blocked most major changes. Until

9882-435: The greater availability of food to eat. Elk do not appear to benefit from thermal cover. The Greater Yellowstone Ecosystem elk herds comprise as many as 40,000 individuals. During the spring and fall, they take part in the longest elk migration in the continental U.S., traveling as much as 168 mi (270 km) between summer and winter ranges. The Teton herd consists of between 9,000 and 13,000 elk and they spend winters on

10004-479: The ground called wallows, in which they urinate and roll their bodies . A male elk's urethra points upward so that urine is sprayed almost at a right angle to the penis. The urine soaks into their hair and gives them a distinct smell which attracts cows. A bull interacts with cows in his harem in two ways: herding and courtship. When a female wanders too far away from the harem's range, the male will rush ahead of her, block her path and aggressively rush her back to

10126-532: The harem. Herding behavior is accompanied by a stretched out and lowered neck and the antlers laid back. A bull may get violent and hit the cow with his antlers. During courtship, the bull is more peaceful and approaches her with his head and antlers raised. The male signals his intention to test the female for sexual receptivity by flicking his tongue. If not ready, a cow will lower her head and weave from side to side while opening and closing her mouth. The bull will stop in response in order not to scare her. Otherwise,

10248-467: The head, neck, and legs during the summer. Forest-adapted Manchurian and Alashan wapitis have red or reddish-brown coats with less contrast between the body coat and the rest of the body during the summer months. Calves are born spotted, as is common with many deer species, and lose them by the end of summer. Adult Manchurian wapiti may retain a few orange spots on the back of their summer coats until they are older. This characteristic has also been observed in

10370-567: The heavy winter coat has been shed. Elk are known to rub against trees and other objects to help remove hair from their bodies. All elk have small and clearly defined rump patches with short tails. They have different coloration based on the seasons and types of habitats, with gray or lighter coloration prevalent in the winter and a more reddish, darker coat in the summer. Subspecies living in arid climates tend to have lighter colored coats than do those living in forests. Most have lighter yellow-brown to orange-brown coats in contrast to dark brown hair on

10492-639: The immediate future. CERCLA authorizes two kinds of response actions: A potentially responsible party (PRP) is a possible polluter who may eventually be held liable under CERCLA for the contamination or misuse of a particular property or resource . Four classes of PRPs may be liable for contamination at a Superfund site: The liability scheme of CERCLA changed commercial and industrial real estate, making sellers liable for contamination from past activities, meaning they can't pass liability onto unknowing buyers without any responsibility. Buyers also have to be aware of future liabilities. The CERCLA also required

10614-531: The indigenous Chilean huemul and other herbivores. This negative impact on native animal species has led the IUCN to identify the elk as one of the world's 100 worst invaders. The introduction of deer to New Zealand began in the middle of the 19th century, and current populations are primarily European red deer, with only 15 percent being elk. In 1905 18 American wapiti were released in George Sound in

10736-547: The insufficient genetic material that rejects monophyly of C. canadensis , some researchers consider it premature to include the Manchurian wapiti as a true subspecies of wapiti, and that it likely needs to be elevated to its own species, C. xanthopygus . The Chinese forms (the Sichuan deer , Kansu red deer , and Tibetan red deer ) also belong to the wapiti, and were not distinguishable from each other by mitochondrial DNA studies. These Chinese subspecies are sometimes treated as

10858-556: The largest antlers while the Altai wapiti has the smallest. Roosevelt bull antlers can weigh 18 kg (40 lb). The formation and retention of antlers are testosterone -driven. In late winter and early spring, the testosterone level drops, which causes the antlers to shed. During the fall, elk grow a thicker coat of hair, which helps to insulate them during the winter. Both male and female North American elk grow thin neck manes; females of other subspecies may not. By early summer,

10980-666: The late 1990s, they were reintroduced and recolonized in the states of Wisconsin , Kentucky , North Carolina , Tennessee , Georgia , Virginia and West Virginia . In the state of Kentucky, the elk population in 2022 had increased to over 15,000 animals. In 2016, a male elk, likely from the Smoky Mountains population, was sighted in South Carolina for the first time in nearly 300 years. Once locally extinct, dispersing elk are now regularly spotted in Iowa , although

11102-490: The lawsuit. The Court awarded costs to U.S. Fish and Wildlife Service. In 2018, several Colorado school districts voted to ban students from attending school-sanctioned trips to the former Rocky Flats plant, citing concerns about the area’s previous designation as a Superfund site. In mid-November, after the elections, Democratic majority leaders of both the State House and Senate (both representing nearby Boulder) joined

11224-444: The lead smelters in 1974, then reduced its lead regulations in 1976. It wasn't until 1981 that the EPA commissioned a study on the lead contamination in this neighborhood and found the same results that had been found a decade earlier. In 1983, the surrounding day cares had to close due to the lead exposure while the lead smelter remained operating. It was later revealed that EPA Deputy Administrator John Hernandez had deliberately stalled

11346-412: The mating season, which may begin in late August. Males try to intimidate rivals by vocalizing and displaying with their antlers. If neither bull backs down, they engage in antler wrestling, sometimes sustaining serious injuries. Bulls have a loud, high-pitched, whistle-like vocalization known as bugling , which advertise the male's fitness over great distances. Unusual for a vocalization produced by

11468-560: The meaning of the word "elk" to English-speakers became rather vague, acquiring a meaning similar to "large deer". The name wapiti is from the Shawnee and Cree word waapiti (in Cree syllabics : ᐙᐱᑎ or ᐚᐱᑎ ), meaning "white rump". There is a subspecies of wapiti in Mongolia called the Altai wapiti ( Cervus canadensis sibiricus ), also known as the Altai maral. According to

11590-515: The mid-1990s, most of the funding came from an excise tax on the petroleum and chemical industries, reflecting the polluter pays principle. Even though by 1995 the Superfund balance had decreased to about $ 4 billion, Congress chose not to reauthorize collection of the tax, and by 2003 the fund was empty. Since 2001, most of the funding for cleanups of hazardous waste sites has come from taxpayers. State governments pay 10 percent of cleanup costs in general, and at least 50 percent of cleanup costs if

11712-517: The party either cannot be found or is unable to pay for the cleanup, the Superfund law originally paid for site cleanups through an excise tax on petroleum and chemical manufacturers. The last full fiscal year (FY) in which the Department of the Treasury collected the excise tax was 1995. At the end of FY 1996, the invested trust fund balance was $ 6.0 billion. This fund was exhausted by

11834-436: The potentially responsible parties (PRPs), reflecting the polluter pays principle . However, 30% of the time the responsible party either cannot be found or is unable to pay for the cleanup. In these circumstances, taxpayers had been paying for the cleanup operations. Through the 1980s, most of the funding came from an excise tax on petroleum and chemical manufacturers. However, in 1995, Congress chose not to renew this tax and

11956-525: The production of ground antler and velvet supplements is also a thriving naturopathic industry in several countries, including the United States, China and Canada . The elk is hunted as a game species, and their meat is leaner, and higher in protein , than beef or chicken . By the 17th century, Alces alces (moose, called "elk" in Europe) had long been extirpated from the British Isles , and

12078-689: The program in 1986 through an act amending CERCLA. The Superfund Amendments and Reauthorization Act of 1986 (SARA) added minimum cleanup requirements in Section 121 and required that most cleanup agreements with polluters be entered in federal court as a consent decree subject to public comment (section 122). This was to address sweetheart deals between industry and the Reagan-era EPA that Congress had discovered. In 1994 President Bill Clinton issued Executive Order 12898, which called for federal agencies to make achieving environmental justice

12200-483: The program in early years, during the Ronald Reagan administration , was ineffective, with only 16 of the 799 Superfund sites cleaned up and only $ 40 million of $ 700 million in recoverable funds from responsible parties collected. The mismanagement of the program under Anne Gorsuch Burford , Reagan's first chosen Administrator of the agency, led to a congressional investigation and the reauthorization of

12322-466: The refuge in exchange for a 300-foot transportation corridor along the refuge's eastern boundary. In September 2015, the wildlife refuge opened for two guided hikes. It officially opened to the public Sep. 15, 2018. During a $ 7 billion Superfund cleanup, millions of environmental data points (soil, air, surface water, ground water, sediment) were collected from thousands of sampling locations. The results of this environmental investigation are presented in

12444-429: The refuge’s trails on September 15, 2018. The Comprehensive Conservation Plan (CCP) emphasizes wildlife and habitat conservation , and a moderate level of wildlife-dependent public use. On April 17, 2015, the U.S. Court of Appeals terminated objections against a 2011 land exchange affecting the refuge. This exchange added over 600 acres of land to refuge and acquired over 1,200 acres of subsurface mineral rights beneath

12566-407: The renewed call to close the refuge to the public. Elk Various Cervus elaphus subspecies The elk ( pl. : elk or elks ; Cervus canadensis ), or wapiti , is the second largest species within the deer family, Cervidae , and one of the largest terrestrial mammals in its native range of North America and Central and East Asia . The word "elk" originally referred to

12688-687: The restoration of ecosystem services. For the federal government, EPA, US Fish and Wildlife Service, or the National Oceanic and Atmospheric Administration may act as natural resource trustees. The US Department of Interior keeps a list of the natural resource trustees appointed by state's governors. Federally recognized Tribes may act as trustees for natural resources, including natural resources related to Tribal subsistence, cultural uses, spiritual values, and uses that are preserved by treaties. Tribal natural resource trustees are appointed by tribal governments. Some states have their own versions of

12810-555: The revision of the National Oil and Hazardous Substances Pollution Contingency Plan 9605(a)(NCP). The NCP guides how to respond to releases and threatened releases of hazardous substances , pollutants, or contaminants. The NCP established the National Priorities List, which appears as Appendix B to the NCP, and serves as EPA's information and management tool. The NPL is updated periodically by federal rulemaking. The identification of

12932-532: The same species (adapted to local environments through minor changes in appearance and behavior). Populations vary in antler shape and size, body size, coloration and mating behavior. DNA investigations of the Eurasian subspecies revealed that phenotypic variation in antlers, mane and rump patch development are based on "climatic-related lifestyle factors". Of the six subspecies of elk known to have inhabited North America in historical times, four remain, including

13054-627: The sensitive endemic ecosystems and species it encounters. As a member of the Artiodactyla order (and distant relative of the Bovidae ), elk are susceptible to several infectious diseases which can be transmitted to and/or from domesticated livestock . Efforts to eliminate infectious diseases from elk populations, primarily by vaccination , have had mixed success. Some cultures revere the elk as having spiritual significance. Antlers and velvet are used in traditional medicines in parts of Asia;

13176-497: The species "red deer", but noted in parentheses that they were "for their unusual largeness improperly termed Elks by ignorant people". Both Thomas Jefferson 's 1785 Notes on the State of Virginia and David Bailie Warden 's 1816 Statistical, Political, and Historical Account of the United States used "red deer" to refer to Cervus canadensis . Members of the genus Cervus (and hence early relatives or possible ancestors of

13298-583: The species as least-concern species . The habitat of Siberian elk in Asia is similar to that of the Rocky Mountain subspecies in North America. During the Late Pleistocene their range was much more extensive, being distributed across Eurasia, with remains being found as far west as France. These populations are most closely related to modern Asian populations of the elk. Their range collapsed at

13420-424: The spring, elk have had some impact on aspen groves which have been declining in some regions where elk exist. Range and wildlife managers conduct surveys of elk pellet groups to monitor populations and resource use. Research in the Greater Yellowstone Ecosystem has found that supplemental feeding of concentrated alfalfa pellets leads to significant alterations in the elks' microbiome . The elk gut microbiome

13542-508: The start of the Holocene, possibly because they were specialized to cold periglacial tundra-steppe habitat. When this environment was replaced largely by closed forest the red deer might have outcompeted the elk. Relictual populations survived into the early Holocene (until around 3000 years ago) in southern Sweden and the Alps, where the environment remained favorable. Elk were also present in

13664-424: The state operated the facility responsible for contamination. By 2013 federal funding for the program had decreased from $ 2 billion in 1999 to less than $ 1.1 billion (in constant dollars). In 2001, the EPA used funds from the Superfund program to institute the cleanup of anthrax on Capitol Hill after the 2001 anthrax attacks . It was the first time the agency dealt with a biological release rather than

13786-837: The subspecies is the Roosevelt elk ( C. c. roosevelti ), found west of the Cascade Range in the U.S. states of California , Oregon and Washington , and in the Canadian province of British Columbia . Roosevelt elk have been introduced into Alaska , where the largest males are estimated to weigh up to 600 kg (1,300 lb). More typically, male Roosevelt elk weigh around 318 to 499 kg (701 to 1,100 lb), while females weigh 261 to 283 kg (575 to 624 lb). Male tule elk weigh 204–318 kg (450–701 lb) while females weigh 170–191 kg (375–421 lb). The whole weights of adult male Manitoban elk range from 288 to 478 kilograms (635 to 1,054 lb). Females have

13908-399: The two are distinct species . The elk's wider rump-patch and paler-hued antlers are key morphological differences that distinguish C. canadensis from C. elaphus . Although it is currently only native to North America, Central , East and North Asia , elk once had a much wider distribution in the past; prehistoric populations were present across Eurasia and into Western Europe during

14030-568: The two species have freely inter-bred in New Zealand 's Fiordland National Park . The cross-bred animals have resulted in the disappearance of virtually all pure elk blood from the area. Key morphological differences that distinguish C. canadensis from C. elaphus are the former's wider rump patch and paler-hued antlers. There are numerous subspecies of elk described, with six from North America and four from Asia, although some taxonomists consider them different ecotypes or races of

14152-663: The types of plants and trees found, and in other animal and plant species dependent upon them. As in Chile and Argentina, the IUCN has declared that red deer and elk populations in New Zealand are an invasive species. Elk have played an important role in the cultural history of a number of peoples. Neolithic petroglyphs from Asia depict antler-less female elk, which have been interpreted as symbolizing life and sustenance. They were also frequently overlaid with boats and associated with rivers, suggesting they also represented paths to

14274-609: The underworld. Petroglyphs of elk were carved into cliffs by the Ancestral Puebloans of the southwestern U.S. hundreds of years ago. The elk was of particular importance to the Lakota and played a spiritual role in their society. The male elk was admired for its ability to attract mates, and Lakota men will play a courting flute imitating a bugling elk to attract women. Men used elks' antlers as love charms and wore clothes decorated with elk images. The Rocky Mountain elk

14396-415: The wild. In some subspecies that suffer less predation, they may live an average of 15 years in the wild. As is true for many species of deer, especially those in mountainous regions, elk migrate into areas of higher altitude in the spring, following the retreating snows, and the opposite direction in the fall. Hunting pressure impacts migration and movement. During the winter, they favor wooded areas for

14518-594: Was first noticed in the state of Washington in the late 1990s in the Cowlitz River basin, with sporadic reports of deformed hooves. Since then, the disease has spread rapidly with increased sightings throughout southwest Washington and into Oregon. The disease is characterised by deformed, broken, or missing hooves and leads to severe lameness in elk. The primary cause is not known, but it is associated with treponeme bacteria, which are known to cause digital dermatitis in commercial livestock. The mode of transmission

14640-426: Was one of 13 nuclear weapons production facilities in the United States during the Cold War and was managed by the U.S. Department of Energy (DOE). The plant operated from 1952 to 1994 with manufacturing activities taking place in the center portion of the site with a large buffer zone around the area. Nuclear production work stopped briefly to address environmental and safety concerns, and was resumed in 1990. In 1992,

14762-532: Was recognized as a relative of the red deer ( Cervus elaphus ) of Europe, and so Cervus canadensis were referred to as "red deer". Richard Hakluyt refers to North America as a "lande ... full of many beastes, as redd dere" in his 1584 Discourse Concerning Western Planting . Similarly, John Smith 's 1616 A Description of New England referred to red deer. Sir William Talbot 's 1672 English translation of John Lederer 's Latin Discoveries likewise called

14884-655: Was renamed the Rocky Flats Environmental Technology Site as of 1994. Through the Rocky Flats National Wildlife Refuge Act of 2001, the site was established as a national wildlife refuge while cleanup of the site was underway. With oversight from the EPA and Colorado Department of Public Health and the Environment (CDPHE), the DOE completed the $ 7 billion cleanup in 2005. The DOE still maintains 1,300 acres as part of their legacy management for long-term care and maintenance, and to ensure
