Placer mining of alluvial deposits is also governed under the Mining Law of 1872 and is associated with damage to asthma symptoms toddler buy on line ventolin aquatic life asthma symptoms and joint pain buy 100mcg ventolin overnight delivery. Related concerns also pertain to asthma symptoms and joint pain purchase ventolin with mastercard surface coal mining, which is regulated by a different under-protective law (Surface Mining Control and Reclamation Act of 1977). Impacts to fisheries from hardrock metal mining result from both abandoned and active mines. Under the Mining Law of 1872, mining companies are not required to provide adequate insurance for clean up and reclamation of federal lands. Such ongoing water contamination threatens drinking water supplies, valuable fisheries, wildlife, agriculture, recreation, tourism, human health, and industries that rely on clean water. Most high-grade, accessible mineral deposits in the United States are already exploited; therefore, new hardrock mining ventures generally focus on low-grade ore deposits. The Mining Law of 1872 and relatively high prices allow for low-grade ore to be marginally profitable because mining corporations are not required to purchase sufficient reclamation insurance. If there is a disaster or massive reclamation expense, they can simply abandon the site and declare bankruptcy. The quantity of waste material generated can be massive, with mine waste areas covering hundreds of hectares and containing tens to hundreds of millions of tons of spoil. For example, the proposed Pebble Mine in the headwaters of Bristol Bay, Alaska, has an estimated mineral resource of less than 1% copper, gold, and molybdenum; 99% of the estimated 7. The processes used to access and extract minerals in modern mining operations create extensive ecosystem disturbance that can lead to long-term adverse effects to ground water, aquifers, surface water, aquatic resources, terrestrial vegetation, wildlife, soils, air, and cultural resources. In remote areas, road construction and increased human activity lead to a variety of ecological effects, either directly related to the roads or the increased number of people accessing the area. To reach and extract desired minerals, most hardrock mining operations displace massive amounts of soil and rock, either at the surface or underground. Waste rock, spent ore, or tailings are generally disposed of in large heaps, ponds, or tailing impoundments, which can occupy hundreds of hectares. If these facilities are poorly designed, improperly constructed, or prematurely abandoned, their failure can lead to long-term contamination of surface and ground water. Toxic dust from dried-up tailings ponds, open pits, roads, and trucks hauling crushed ore can be carried by wind far from the mine site and contaminate surface and ground water as well as air and terrestrial vegetation. Desired metals are extracted or leached using chemicals that can be toxic if released into the environment. Exposure of sulfide minerals, frequently associated with metallic ores, can create acidic conditions and leach metals into local waters. Even without acidic conditions, metals can be discharged from mine sites and enter surface water, ground water, and soils. This can cause significant damage to aquatic life, vegetation, and terrestrial wildlife, and poses a hazard for human health. Toxic loading of stream waters can alter the assemblage structure of invertebrates (Clements et al. Those toxic metals also contaminate water and sediment and bioaccumulate in fish tissues (Harper 2009), leading to reduced fitness or death (National Academy of Sciences 1999). Impoundment of water and stream diversions can lead to loss of habitat for fish spawning and rearing. The perception that modern mining techniques are vastly improved over historic methods was recently challenged by a comprehensive study of modern U. For example, the study compared predicted water quality impacts to observed impacts found at a sample of 25 U. Army Corps of Engineers approved a permit application by Coeur Alaska to deposit up to 4. The permit was approved even though Coeur Alaska agreed in its application that these two fish species would be extirpated from the lake by the waste. The Supreme Court decision sets a legal precedent that may allow other mining operations to avoid adherence with Clean Water Act water quality criteria by petitioning the Corps of Engineers to redefine pollutant-containing waste material as fill. Examples of mining impacts on aquatic resources Without responsible laws and policy, and adequate reclamation and remediation, existing and future hardrock mines pose a risk to fish-bearing waters, in addition to the legacy effects of abandoned mines. Numerous examples of valuable fisheries and aquatic ecosystems harmed by hardrock mining exist across the western United States. High metals prices and demand for raw materials have created a modern minerals rush, with existing mines expanding, new claims being staked on public lands, and old mines reopening. Select case studies are presented to exemplify frequent compatibility issues existing between fisheries resource conservation and hardrock mining.

Piloting asthma 3d animation ventolin 100mcg line, and the associated monitoring and evaluation work asthma treatment success rates ventolin 100 mcg low cost, will therefore be fundamental in due course and once components of the Learning Passport are complete asthmatic bronchitis treatment cough purchase 100mcg ventolin overnight delivery. Fourth, and to give additional weight to the output concerning digital (that is, conceptstage work around a digital platform to support the Learning Passport), the Cambridge team has undertaken a broader investigation into digital and EiE to ensure this work is on a firm footing. A wide variety of different sources are examined in the review, reflecting the range of organisations and stakeholders involved in EiE, the relative youth and interdisciplinarity of the academic field of EiE, and the paucity of in-depth reporting on the practice, methodology and efficacy of specific EiE interventions. As a general rule, detailed accounts and systematic analyses of curricula and their effects, failures, and successes in EiE contexts are sparse, and conclusions often have to be drawn from fragmented or anecdotal evidence. This is certainly partly explained by the fact that crises can be quick to develop, and frequently lack the data collection infrastructure necessary for rigorous monitoring and evaluation. However, it is still necessary to note the scarcity of comparable data, and the recognition by contributors to 19 the field of the need to develop an evidence base in relation to the theoretical work already going on (Barakat et al. Activity in this arena continues to grow, and with more substantial records of what does and does not work beginning to inform new projects. How these sources and the literature surrounding EiE have been searched and included in this report is outlined in the methodology appendix (Appendix 1). The emphasis in this section is on identifying the challenges that the Learning Passport aims to tackle, and providing a fuller understanding of the particular dynamics and features of EiE. This includes research that both describes the characteristics of displaced learners in general, and the different challenges they face depending on context. This section also outlines educational interventions and solutions in contexts of displacement, and identifies where the implementation of the Learning Passport can learn from both more and less effective projects, instruments, and policies. This is supported by a literature review informing the discussion of these approaches. These are the key aspects of the Learning Passport itself as a coherent education model. Within each literature review, we first identify as great a consensus as possible within the general (non-EiE) academic literature regarding the optimal development and design of each of these Learning Passport components. Principles derived here are then refined and developed according to existing EiE evidence. It is important to emphasise that the Learning Passport is not conceived of as necessarily digitally reliant from an on-the-ground deployment perspective; but when and where digital support might make a difference to quality it is vital we define how. The final core section of the Report (Section 9) summarises the findings from the above literature reviews, and draws from them the key recommendations for taking the Learning Passport forward. The first is the distillation of particularly important findings and evidence from the literature reviews, which point towards an essential need which the Learning Passport must meet in order to be successful. The 20 second recommends the approach we think is most likely to achieve success, extracted from multiple sources where the evidence does not plainly direct us towards a position. Importantly, both kinds of recommendation are limited in scope to defining and guiding the next steps of the Learning Passport project in particular. While the section as a whole considers the characteristics of EiE provision and key areas of challenge, it first anchors the discussion in an examination of the diverse needs, aims and aspirations of the learners themselves. Prior to that, however, we highlight several more general contextual issues, which are pertinent to the planning and implementation of EiE in whatever context. The first and most obvious point, which nevertheless cannot be overemphasised, is the need to recognise the multiple levels of heterogeneity involved in EiE. Further, these processes of development can overlook local and community understandings and responses to crisis (Weinstein et al. Introduction Displacement contexts present a distinctive set of challenges to learners that manifest in complex ways and in different combinations. This sub-section contextualises EiE learner backgrounds and needs, recognising first and foremost that displaced children are not a discrete category, but experience diverse realities (Boyden & Zharkevich, 2018). It begins by anchoring the discussion in an examination of the aims of learners themselves, recognising that individual objectives and aspirations are hugely shaped by the opportunity structures available (or perceived to be available) to young people. Next it explores how the socio-economic characteristics of learners are shaped by their interactions across different socio-political spaces and points in time.

Water needed for the construction of ice roads and other infrastructure may be withdrawn from rivers and lakes reducing overwintering and spawning habitats or directly affecting fish populations asthmatic bronchitis treatment in homeopathy order 100mcg ventolin fast delivery. Golden Eagles are rare breeders on the Beaufort Sea coastal plain and initiate nesting very early in the spring asthma or allergies buy cheap ventolin online. Gyrfalcons are rare breeders on the coastal plain, and like Golden Eagles, initiate nesting very early in the spring leading to possible conflicts with the exploration activities. Water needed for the construction of ice roads and other infrastructure could be withdrawn from aquatic habitat impacting migrating waterfowl and shorebird populations. The 1002 area of the Refuge is within the territory of the Porcupine Caribou Herd which travels north and south and is a primary subsistence resource for many of the Native people who live in and around the Refuge. Both muskoxen and moose are now rare in this area and on the coastal plain in general; their populations have declined in recent years. Muskoxen may be particularly sensitive to late winter disturbance given nutritional challenges and calving beginning in mid-April. Bears, wolves, and wolverines all occur on the coastal plain, although they are more abundant in the foothills and mountains. Brown bears emerge from their dens from late March through May overlapping with expected seismic exploration activities. A majority of female polar bears of the Southern Beaufort Sea population den in the 1002 area of the Refuge in high densities. Pre-survey logistics for exploration activities will probably increase potential for bear-human conflicts. Now that there is limited sea ice during much of the year, exploration equipment could be transported to the area via barges through a known bowhead whale migration corridor. Pre-survey and staging for exploratory activities may affect subsistence resources in early winter or early spring. Now that there is limited sea ice during much of the year, exploration equipment could be transported to the area via barges through known bearded and ringed seal habitat. The construction of ice or gravel roads and pads, associated infrastructure, and seismic survey may cause direct effects to previously undocumented cultural resources. Exploration activities have the potential to create employment opportunities within communities neighboring the Refuge and may also affect subsistence resource availability. Exploration activities have the potential to affect resource availability by creating disturbances that change caribou and polar bear movements. Pre-survey and staging for exploratory activities may affect subsistence resources in early winter or early spring and these activities remain poorly defined. Noise from vehicles, generators, aircraft, and human presence has the potential to change the natural soundscape during seismic exploration activities. The resulting exploration activities may result in a substantial level of activity in limited areas.

If an applicant submits an exploration plan in any given year with the intention of submitting another exploration plan the following year, the applicant shall describe in its initial plan how its future exploratory activities will be integrated with those proposed under its initial plan. Proposed Surface Geological and Seismic Exploration Current 3-D seismic methods generate images of subsurface structure by sending energy waves into the ground or water and then recording the reflected energy waves upon return. One of the most common methods for creating these energy waves in the Arctic is through vibroseis operations which use truck-mounted vibrators that systematically put variable frequency energy into the earth. The reflected energy image is recorded and then progresses in a manner that results in transect coverage over the entire identified area. Exploration activities generally occur in the winter with crews beginning to mobilize and build ice roads and pads in December (Table 2.
