Stockton Plateau Hydro Project
The Ngakawau Restoration Project is a proposed hydro scheme planned to divert acid mine drainage from coal mines to an ocean outfall to restore water quality of the Ngākawau River, in the northern section of the West Coast of the South Island of New Zealand. The project is a configuration of the Stockton Plateau Hydro Scheme being developed by Hydro Developments (2013) Limited (the successor to Hydro Developments Ltd following voluntary liquidation). Project information can be found at https://hydrodevelopments.co.nz In December 2008 Hydro Developments Ltd applied for resource consent for a 60MW hydro scheme (the Stockton Plateau Hydro Scheme) using polluted water from the Stockton Mine. Consent was granted in January 2010. The scheme was expected to reduce acid mine drainage from the mine into the Ngākawau River, and was supported by the Green Party of Aotearoa New Zealand and other environmental groups. In February 2010 Solid Energy applied for resource consent for an alter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. Int ...

Ngākawau River
The Ngākawau River is a river of the West Coast Region of New Zealand's South Island. It flows generally northwest, reaching the Tasman Sea at Hector. The New Zealand Ministry for Culture and Heritage gives a translation of "the shags" for ''Ngākawau,'' the official name of the river since 21 June 2019. The Charming Creek Railway line used to run alongside Ngākawau River in the Lower Ngākawau Gorge, transporting coal from mines in the Ngākawau River catchment area. The disused bush tram track now forms a section of the Charming Creek Walkway. 3 km into the gorge, Mangatini Stream joins Ngākawau River over the 25 m tall Mangatini Falls. Parts of the Upper Ngākawau Gorge are the only known habitat of the rare daisy '' Celmisia morganii''. Ngākawau River is polluted with acid mine drainage and coal fines from the Stockton Mine. The proposed Stockton Plateau Hydro Project is expected to reduce the levels of pollutants. The Ngākawau Riverwatch environmental gr ...

Resource Consent
A resource consent is the authorisation given to certain activities or uses of natural and physical resources required under the New Zealand Resource Management Act (the "RMA"). Some activities may either be specifically authorised by the RMA or be permitted activities authorised by rules in plans. Any activities that are not permitted by the RMA, or by a rule in a plan, require a resource consent before they are carried out. Definition and nature The term "resource consent" is defined as; * a permit to carry out an activity that would otherwise contravene a rule in a city or district plan. * a permission required for an activity that might affect the environment, and that isn't allowed 'as of right' in the district or regional plan. A resource consent, once granted to an applicant, is neither real nor personal property. Therefore, resource consents cannot be 'owned'; they are 'held' by 'consent holders'. Types A resource consent means any of the following: * land use consent ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stockton Mine
Stockton Mine, on the Stockton Coal Field, is New Zealand's largest opencast mining operation. The entrance to the mine is at the former settlement of Stockton. Extent The coal field is situated between 5 and 10 kilometres linear distance south west of Stockton. The southernmost part of the coal field is only 5 km away from the historic mining town of Denniston. The elevation of the coal field varies between 500 and 1100m above sea level. The Stockton coal field dips to the Northeast with approximately the same dip as the Denniston Coal Field, 15 km to the south. Both fields contain Bituminous Hard Coking Coal. The extracted coal is transported from the mine to an aerial ropeway near Stockton. The coal is transported to Ngakawau using this ropeway, doing away with the dangerous railway operation that plagued the Millerton and Denniston Inclines. From Ngakawau, most of the coal is transported by rail to Lyttelton, where it is exported via ship to steel makers in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid Mine Drainage
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed (e.g. construction sites, subdivisions, and transportation corridors) may create acid rock drainage. In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage. This liquid often contains highly toxic metals, such as copper or iron. These, combined with reduced pH, have a detrimental impact on the streams aquatic environments. The same type of chemical reactions and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Party Of Aotearoa New Zealand
The Green Party of Aotearoa New Zealand ( mi, Rōpū Kākāriki o Aotearoa, Niu Tireni), commonly known as the Greens, is a green and left-wing political party in New Zealand. Like many green parties around the world, it has four organisational pillars (ecological wisdom, social justice, grassroots democracy, and nonviolence). The party's ideology combines environmentalism with left-wing and social-democratic economic policies, including well-funded and locally controlled public services within the confines of a steady-state economy. Internationally, it is affiliated with the Global Greens. The Green Party traces its origins to the Values Party, founded in 1972 as the world's first national-level environmentalist party. The current Green Party was formed in 1990. From 1991 to 1997 the party participated in the Alliance, a grouping of five left-wing parties. It gained representation in parliament at the 1996 election. Historically, the Green Party had two co-leaders, one mal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solid Energy
Solid Energy was the largest coal mining company in New Zealand and is a state owned enterprise of the New Zealand Government. The company was formed from the former government department State Coal Mines. It was then established as a state owned enterprise called Coal Corporation in 1987 (known as Coalcorp), and renamed Solid Energy New Zealand Limited in 1997. In 2015, it had a turnover of NZ$369.8 million and produced 2.8 million tonnes of coal. The company mined extensively in New Zealand's Waikato and the West Coast regions. Approximately half the coal mined was exported, as it is high value with little moisture, sulphur, or other impurities. Much of this is to China, India and Japan where it is used in the power generation and coke industries and for the manufacture of steel and other metals. Major domestic users included the Huntly Power Station and New Zealand Steel at Glenbrook. Solid Energy went into voluntary administration in August 2015. On 31 October 2016 it was ...

Environment Court Of New Zealand
The Environment Court of New Zealand ( mi, Te Kōti Taiao o Aotearoa) is a specialist court for plans, resource consents and environmental issues. It mainly deals with issues arising under the Resource Management Act, meaning that it covers a wide range of potential future effects of planning applications, which can include such areas as traffic congestion, noise/pollution emissions and social and commercial consequences, rather than just the 'ecological' aspects that could be implied by the 'environmental' term. History The history of independent appeal courts addressing environmental matters began with the establishment of Appeal Boards under the Town and Country Planning Act 1953. The first planning appeals were heard in February 1955. The Appeal Boards were replaced by the Planning Tribunal following the passing of the Town and Country Planning Act 1977. The Environment Court replaced the Planning Tribunal as a result of the Resource Management Amendment Act 1996. Jurisdic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voluntary Administration
As a legal concept, administration is a procedure under the insolvency laws of a number of common law jurisdictions, similar to bankruptcy in the United States. It functions as a rescue mechanism for insolvent entities and allows them to carry on running their business. The process – in the United Kingdom colloquially called being "under administration" – is an alternative to liquidation or may be a precursor to it. Administration is commenced by an administration order. A company in administrative receivership is operated by an administrator (as interim chief executive with custodial responsibility for the company's assets and obligations) on behalf of its creditors. The administrator may recapitalize the business, sell the business to new owners, or demerge it into elements that can be sold and close the remainder. Most countries distinguish between voluntary (board-decided) and involuntary (court-decided) receivership. In voluntary administrative receivership, the a ...

List Of Power Stations In New Zealand
This is a list of power stations in New Zealand. The list is not exhaustive – only power stations over 0.5 MW and significant power stations below 0.5 MW are listed. Power plants in New Zealand have different generating roles – for baseload, intermediate or peaking. Baseload generators are those that run continuously (except for maintenance), and include all geothermal and run-of-the-river hydroelectric plants, which must 'use it or lose it'. Intermediate generators are load-following power plants. Peaking power plants generate only for minutes or hours at a time, during the sharpest peaks in electricity demand.

Buller District
Buller District is one of 53 districts of New Zealand, and is within the West Coast Region. It covers Westport, Karamea, Reefton and Inangahua Junction. Buller District's overall land area is . The district is administered by the Buller District Council with the seat in Westport, in which 45% of the district's population live. History It is understood by the carbon dating of Umu (ovens) that the Maori people settled in this region some 700 years ago. The district takes its name from the Buller River, itself named for Charles Buller, a Member of Parliament in the United Kingdom of Great Britain and Ireland (UK) and director of the New Zealand Company, a UK-based company established in the early 19th century with a royal charter supporting colonisation efforts of New Zealand. During the period 1853 to 1876, the current area of Buller District was administered as part of Nelson Province. With the Abolition of Provinces Act 1876, much of the current area of Buller District w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Stations In New Zealand
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
