Environmental Impact Assessment Report

Environmental Impact Assessment is very advanced process of forecasting influence on environment of planned operation, in this case- High Speed 2. It is crucial to do EIA before any construction works commence, it will allow designers to change or improve the project in order to minimise negative consequences of it.
This paper include analyse of main environmental issues, such as: impact on agriculture, forestry and soils; air quality; climate, community, cultural heritage, ecology, land quality, visual effects, noise/vibration, waste material resources and water resources/ flood risk.

Environmental impact assessment is the formal mechanism used to predict positive and negative environmental consequences of a project prior to the decision to move forward with the planned action.

Description of the development
HS2 is a project of high-speed railway between London Luton and Birmingham, and future extensions towards Leeds and Manchester. Construction works will be held in two phases, the first of them starts in 2026 (London- West Midlands), and second phase starts in 2032 (North West England and West Yorkshire). The biggest aim of creating this railway is to radically reduce travel time, for example: journey from London to Birmingham will take approximately 35 minutes less than it takes now.
HS2 project is a result of cooperation of Department for Transport (DfT) and High Speed Two Limited (HS2 Ltd.). This investment is necessary due to increasing need of long distance travels- in the past 15 years it has doubled and it is still growing. This is the reason why British railways must be improved, especially its capacity, connectivity and duration of journeys. (GOV.UK. 2013)
They designed the route between London and Birmingham taking into account minimising the impact on local environment and communities.

Regulatory and policy background
One of the most important stepping stones on the way to HS2 was High Speed Rail Preparation Act (paving Act). It passed both Houses of Parliament last year. It guarantees monies for preparatory work (including environmental assessment) as well as compensations for those negatively affected by the railway. (GOV.UK. 2013)
The High Speed Two hybrid Bill will seek the necessary legal powers to enable the construction and operation of the first phase of HS2 railway between London and the West Midlands. (GOV.UK. 2013) .
To assess impact on environment, the designers of HS2 project had to follow the procedure, shown below- Figure 1.

Figure 1. – Environmental Impact Assessment (Review of HS2 London to West Midlands Appraisal of Sustainability, A report to Government by HS2 Ltd, January 2012)

Methodology of assessing environmental impact of a HS2 project is very precisely described in “HS2 London to West Midlands EIA Scope and Methodology Report”. First step of EIA is to establish the broad scope and methodology of environmental studies that need to be carried out for each environmental topic separately. To do so, they need to undertake surveys, review engineering alternatives- based on these they will identify the local extent of potential impacts and predict what actions should be avoided or reduced. In following this procedure it is fundamental to consider policies, guidelines and legislation and best practice relevant to EIA. After assessing all likely environmental impact, the designers must find a way to minimize negative impact of the project- the hierarchy of mitigation is shown in Figure 2.

Figure 2 – Mitigation hierarchy (HS2 London to West Midlands EIA Scope and Methodology Report- A report to HS2 Ltd by Arup/URS)

As we can see, the most preferable is to avoid or minimize negative influence on environment. If these two are impossible to accomplish, the engineers must try to abate some parts of the design e.g. add noise barriers to the project. Repair is usually required during construction works- its impact is often only temporary. Thing that inventors are trying to prevent is to compensate for any losses or damages caused by the project. To decide which of procedures is the most relevant to particular environmental effect- professional judgment must be made.
Afterwards, draft of Environmental Statement can be prepared and publicly consulted. Then final version of ES can be formed.

Environmental impact:
EIA covers all issues listed below:
Agriculture, Forestry and Soils: such as: farming and other rural enterprises, farm buildings, related land use and woodland planting, ancient woodlands;
The designers assures, that good quality agricultural soil will be stripped prior to construction and stored appropriately for future use.
Owners and operators of affected agricultural holdings will be entitled to receive compensation for any losses that HS2 will cause.
Air Quality: this section applies to dust and emissions/pollutants related to construction and operational traffic.
Inventors guaranteed that the railway will operate efficient, non-polluting (at source) electrically powered trains to minimise air pollution.
Community: general effects on residential property, community facilities and communities as a whole: e.g. effects on public footpaths, bridleways, parks and gardens. Temporary presence of construction workers;
All homes which are located close to the planned route have already lost 40 per cent of their value, some of them will be demolished due to the project, but the HS2 Ltd. assures that all household owners will receive compensation for any losses.
Cultural Heritage: this applies to: ancient burials, old buildings, designated assets, buried archaeology, historic landscapes.
It is inevitable that hundreds of historical houses will be demolished, although there are projects to redeem these houses and the owners will get proper compensation for any losses and damages.
Ecology: applies to: protected species, wildlife, habitat disturbance.
HS2 Ltd. will create new habitats and other features of ecological value to compensate for unavoidable losses and reasonably limit the amount of land required for the construction and operation of the project
Landscape and Visual Assessment: Any new large infrastructure project, especially road and railway routes, will have impacts on landscape. In this respect HS2 Ltd. have already incorporated a large number of changes along the route that have been driven by an approach to minimise the impact, for example: more than half of the 140 kilometre route will be in tunnels or cuttings. Apart from this, earth mounding and planting will be used to integrate the project into the local landscape.
Socio-economics: trade, employment, business and the economy/markets (local and national). E.g. isolation effects on businesses or opportunities for jobs during construction/operation. Labour supply. Changes in demographics also included here;
As we can read on official HS2 website: “HS2 will revolutionise our railways, create thousands of jobs, bring major cities closer together, generate investment in neglected areas and provide passengers with an unprecedented travel experience. Explore how HS2 will transform Britain's capacity, connectivity, trains, passenger experiences and travel sustainability while driving growth and regeneration.”
Sound, noise and vibration: It is impossible to avoid this kind of impact, but to reduce negative influence, the designers of HS2 will provide noise barriers and plant trees along the railway (shown below in the figure 3) Figure 3. (from HS2 Ltd's 'Appraisal of Sustainability”)

Traffic and Transport: covers all modes of transport, to include walking and cycling, road and rail, waterways and air.
Preston (2012) noted that even though the inventors predicted continuing growth in the demand for long distance rail travel, it is not 100% certain - Eurostar demand has been below forecast levels in part because the London to Paris/Brussels rail market has not grown as fast as expected due to increased competition.
Waste and Material Resources: off-site disposal to landfill of solid waste from construction and demolition activities (and related earthworks design). Includes waste generated. Disposal of contaminated soil; and
The designers will manage excavated materials locally to achieve balance of cut and fill volumes so as to reduce the number of heavy lorries on local roads;
Water Resources and Flood Risk Assessment: Surface water features, both natural and artificial and ground water. Flood risk and drainage networks). Disposal of liquid waste.
HS2 Ltd. will avoid or reduce impacts on floodplains and flood storage areas and provide balancing ponds to control surface water run-off.
(High-Speed Rail London- West Midlands- Bill: Summary of issues raised by comments on the environmental statement. London)

As every huge project, HS2 is no exception - it will have some negative impact on the environment, but the designers did everything to minimize it as much as possible. Environmental assessment has been the foundation of route selection, design development, arrangements for construction and operation of the railway, and measures to mitigate the project’s environmental impacts. HS2 Ltd. put very big effort into reducing adverse environmental influence of their project. They provided very detailed description of the development.
A few words about sustainability of HS2. Despite many negative reviews, there are some obvious benefits of this project. One of the indicators that will be greatly improved is travel time, what will make much easier, for example, to work in London and live in Birmingham at the same time, without spending half of a day in a train or car. And as we know, life in London is much more expensive than in West Midlands. Thus, people will save a lot of time and money by using HS2. Also authors of the official HS2 webpage convince us: “HS2 will revolutionise our railways, create thousands of jobs, bring major cities closer together, generate investment in neglected areas and provide passengers with an unprecedented travel experience. Explore how HS2 will transform Britain's capacity, connectivity, trains, passenger experiences and travel sustainability while driving growth and regeneration.” (HS2. 2012).

- Environmental Impact Assessment is one of first steps in designing,
- Based on EIA, the designers will know what need to be changed or improved to reduce impact on environment
- EIA allows to cancel whole project if it has too negative impact on environment
- The HS2 designers aim was to ensure that, during and after construction works of the project, negative environmental impact will either be avoided or mitigated
- The law requires the Environmental Statement to include a description of the measures envisaged in order to avoid, reduce and, if possible, fix the significant adverse effects of the project.
- Environmental assessment has been the foundation of route selection, design development

Environmental Impact of the Gulf War

...Environmental Impact of the Gulf War The Gulf War of 1990-1991 seemed to have been a decisive victory from a militarily and tactical point of view. From an environmental point of view the Gulf War was a disaster that ravaged the local ecosystem that the conflict touched. Both the Iraqi aggressors and the allied forces committed crimes against the environment ranging from use of minerals such as depleted Uranium for weapons manufacturing, and deliberate dumping of oil into the Gulf. The dumped oil spills had a major impact on the ecosystem around the Gulf region and in the Gulf itself. The actions that were taken and not taken from both parties (Iraqi troops, and allied forces) had a negative implication on the resources, and ecosystem of the Gulf. There were three reasons as to why the Gulf war came about. First, Iraq had long claimed that Kuwait was a part of its own country. This claim led to many confrontations and hostility between the two countries. Along with Saddam Hussein’s defeated invasion attempt of Iran, it can be argued that he sought to find a weaker foe in order to conquer which happened to be Kuwait. Second, rich deposits of crude oil had straddled the borders of the ill-defined desert area, and Iraq claimed that Kuwaiti oil riggers were illegally tapping this rich reserve that was claimed to be part of Iraqi fields. The Middle Eastern deserts make it so that border differences between local countries are hard to distinguish, thus leading to conflicts.......

With this type of technology venture, there would be huge ramifications in regards to the impact on the environment of Mexico. First and foremost, if the iPhone 4 were to be sold in Mexico that would mean that the quality of Mexico’s cellular networks would have to be upgraded. Apple would have to invest and perhaps help with the strategy in upgrading Mexico’s data network so that it would be able to handle the increased amount of data traffic over the air. This would mean more cell phone towers and hub stations that help increase the data bandwidth and enable more users to use a Smartphone device, such as the iPhone 4. Many people do not realize that the cost to build a cell phone tower can be rather expensive plus that facts that you need to have zoning rights to put a tower in an area where some people do not want it. Especially in tourist areas where the landscape is beautiful, it can be an eye sore to have a huge tower built right in the middle of it. Luckily there are many designs today where these towers can be created in an inconspicuous manner and are hidden from the public view. Another challenge to this obstacle would be getting permission to build these towers and having to deal with a......

BENEFITS 1. Environmental Awareness Tourism has created environmental awareness in two ways:  First, contact with scenic areas has raised man’s awareness of the earth’s beauty and made it easier for him to see and enjoy it with minimum damage.  Second, environmental awareness has been heightened by mass tourism 2. Conservation Conservation and prevention of the environment not only benefits the local area but they also determine the future of tourism.  First, the local residents benefit from the preservation.  Second, tourism for as long as it draws tourist, will continue to be socio-economic and culture asset. The aim of National Park Services, with the inclusion of conservation, is much broader now than it was in the past. The national park in East Africa, Kenya and Tanzania were founded to protect wildlife. Clare Gunn cited the following factors which led to the conservation movement: 1.

Impact of Environmental Regulations on Small Business

...Lorna Deans Cornerstone Seminar IDS101 Dec 21, 2012 The Impact of Environmental Regulation on Small Businesses Small businesses are critical to the U.S. economy. They create about one-half of all private sector jobs and generate more than half of all revenues. It is critical to take into consideration how regulations and litigation impact small businesses. The biggest impact consideration is the financial impact to a companies’ bottom line (RAND Corporation). The U.S. economy slowly coming out of a recession, small businesses are struggling to overcome imposing environmental regulations from Washington. With record low rates of small business startups, people would argue that these imposing regulations are turning out all positive results. Small businesses unlike their larger business counterparts, cannot afford to hire specialty firms to help them make their way through these regulations. It also takes a lot of time and money to keep up with all the rules imposed on them. Such regulations impose costs on small businesses ranging from capital investments in upgrading current working environments to civil or criminal penalties. An effect of these regulations would be lower hiring projections for the near future. Other effects could be that the U.S. will not see a significant change in the unemployment rates and small businesses will lose out on revenues generated by hiring more employees (Alford). The definition of a small business is one that employs 500......

Goerge Philander’s “The Ozone Hole, A Cautionary Tale” was informational too, however, the piece also discussed global reactions to the rapid climate change. Thomas R. Karl and Kevin E. TrenBerth’s “Modern Global Climate Change”, focused on the intensity of anthropogenic influences of climate change and the dismal projection of the future. In “Stabilization Wedges: Solving the Climate Problem for the Next Fifty Years With Current Technologies”, Stephen Pacala and Robert Socolow went in a different direction and presented a positive outlook on the improvement of the Earth’s current environmental state and introduced the idea of stabilization wedges. Lastly, the IPCC 2014 Summary report is a report that focused on looking at how nations can act to limit climate change.

Environmental Impact

...The environmental impact of paper is significant, which has led to changes in industry and behaviour at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanised harvesting of wood, disposable paper has become a cheap commodity. This has led to a high level of consumption and waste. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry. The production and use of paper has a number of adverse effects on the environment which are known collectively as paper pollution. Pulp mills contribute to air, water and land pollution. Discarded paper is a major component of many landfill sites, accounting for about 35 percent by weight of municipal solid waste (before recycling).[1] Even paper recycling can be a source of pollution due to the sludge produced during de-inking. According to a Canadian citizens organization, "People need paper products and we need sustainable, environmentally safe production." The amount of paper and paper products is enormous, so the environmental impact is also very significant. It has been estimated that by 2020 paper mills will produce almost 500,000,000 tons of paper and paperboard per year, so great efforts are needed to ensure that the environment is protected during the production, use and recycling/disposal of this enormous volume......

Environmental Impact of a Foam Cup

...oil extraction, refining, chemical transformation, distribution, retail, and disposal. Both the production and disposal of foam cups also have serious environmental impacts and its widespread use has generated significant recycling issues. Raw Material Extraction The lifecycle of a foam cup begins with the extraction of crude oil by oil rigs both on-shore and from beneath the sea floor in the Gulf of Mexico. These rigs require large amounts of manpower and energy and freshwater to operate, and pose a real threat for potential spills which can damage and harm marine ecology. Refining of Material Crude oil is unusable as it comes out of the ground. It must be purified and separated into its useful components, which is where the oil refinery comes in. The US Gulf Coast has the largest concentration of refineries in the world. It is from the refinery that we get transportation fuels such as gasoline, diesel, and jet fuel. It is also where we get raw materials for the chemical industry. For the production of plastics we get naphtha, which are 5 to 9 carbon chains that can be used as the raw material in a plant to make ethylene and benzene. Benzene and ethylene are subsequently reacted in another plant to make styrene. Refineries are large, energy-intensive plants which have a significant environmental impact. They generate greenhouse gases due to their high energy use, many refineries, particularly older ones, have had issues with hydrocarbon contamination...

The Environmental Impacts of Pesticides

...The environmental impact of pesticides consists of the effects of pesticides on non-target species. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Runoff can carry pesticides into aquatic environments while wind can carry them to other fields, grazing areas, human settlements and undeveloped areas, potentially affecting other species. Other problems emerge from poor production, transport and storage practices. Over time, repeated application increases pest resistance, while its effects on other species can facilitate the pest's resurgence. Each pesticide or pesticide class comes with a specific set of environmental concerns. Such undesirable effects have led many pesticides to be banned, while regulations have limited and/or reduced the use of others. Over time, pesticides have generally become less persistent and more species-specific, reducing their environmental footprint. In addition the amounts of pesticides applied per hectare have declined, in some cases by 99%. However, the global spread of pesticide use, including the use of older/obsolete pesticides that have been banned in some jurisdictions, has increased overall. Agriculture and the environment The arrival of humans in an area, to live or to conduct agriculture, necessarily has environmental impacts. These range from simple crowding out of wild plants in favor of more desirable......

Environmental and Economic Impact Essay

...Environmental and Economic Impact Assessment By Lori Wiley May 16, 2016 Eco/370 In Chapter 11 a narrow strip of land that is considered rainforest country is discussed. This land is known as the Tongass National Forest. Due to it being so scarce and the cutting of trees for timber, it poses a great threat compared to the tropical rainforests. This forest was once untouched and preserved. Over recent years and decades land has been converted into private land and owned by the state of Alaska. President Clinton put the Roadless Area Conservation Rule in force to protect nearly one-third of the 192 million acres in the national forest system, nationwide (B.C Field, 2013). The Bush administration promised to uphold the rule when elected. However, the Bush administration lied and withdrew it. This left 9.3 million acres without protection. This puts much of the heart of Alaska's rainforest, once again, back on the chopping block (B.C Field, 2013). The big ancient tree forest is a big target to the logging companies. These big trees provide much needed shelter to wildlife living within the forest. The timber industry is tearing out the heart of the Tongass Rainforest. The problem with logging is it is somewhat economic. Logging on private and public lands has been heavily subsidized, and industry's plan has been to log the best of the forest first, then the best of what is left. About half of forest covered with big trees and two-thirds of the biggest-tree stands have......

Environmental Impacts of Dams

...Environmental Impacts of Dams By Tania M. Brown Instructor: Timothy Butcher Environmental Site Assessment 10/27/2008 Throughout the past few years, the negative impacts of dams have become so well known that most countries have stopped building them altogether and are now forced to invest their money into fixing the problems created by existing dams. The environmental impacts of dams have come under renewed examination in recent years. Dam advocates have historically understood that dams largely improve the status of water-related energy and environmental issues by, for example, producing hydroelectric power and increasing the water supply for irrigation. The construction of large dams completely change the relationship of water and land, destroying the existing ecosystem balance which, in many cases, has taken thousands of years to create. Currently there are around 40,000 large dams which obstruct the world's rivers, completely changing their circulation systems: this is not going to occur without dire environmental impacts. . Dam advocates have historically understood that dams largely improve the status of water-related energy and environmental issues by, for example, producing hydroelectric power and increasing the water supply for irrigation. The damming of a river creates a reservoir upstream from the dam. The reservoir waters spill out into the surrounding environments, flooding the natural habitats that existed before the dam’s......
