EPA sets national coal ash regulations for US
22 December 2014US: The Environmental Protection Agency (EPA) has announced the first national regulations to provide for the safe disposal of coal ash from coal-fired power plants. The ruling establishes safeguards to protect communities from coal ash impoundment failures and establishes safeguards to prevent groundwater contamination and air emissions from coal ash disposal.
"The EPA is taking action to protect our communities from the risk of mismanaged coal ash disposal units and putting in place safeguards to help prevent the next catastrophic coal ash impoundment failure, which can cost millions for local businesses, communities and States," said EPA Administrator Gina McCarthy.
The new federal regulations include:
- The closure of surface impoundments and landfills that fail to meet engineering and structural standards and will no longer receive coal ash;
- Reducing the risk of catastrophic failure by requiring regular inspections of the structural safety of surface impoundments;
- Restrictions on the location of new surface impoundments and landfills so that they cannot be built in sensitive areas such as wetlands and earthquake zones;
- Protecting groundwater by requiring monitoring, immediate clean up of contamination and closure of unlined surface impoundments that are polluting groundwater;
- Protecting communities using fugitive dust controls to reduce windblown coal ash dust;
- Requiring liner barriers for new units and proper closure of surface impoundments and landfills that will no longer receive coal combustion residues.
In response to feedback on the proposal, the ruling clarifies the technical requirements for coal ash landfills and surface impoundments under Subtitle D of the Resource Conservation and Recovery Act (RCRA), the country's primary law for regulating solid waste. Implementation of the technical requirements will be reported through disclosure to States, and communities. Examples of this include power plants providing information to the public and States and new transparency requirements, including recordkeeping and reporting requirements, as well as the requirement for each facility to post specific information to a publicly-accessible website. This final rule also supports the responsible recycling of coal ash by distinguishing safe, beneficial use from disposal.
NTPC’s power plant sets up bagging machines for fly-ash
16 October 2014India: In response to local concerns over the open-filling of fly-ash, an NTPC-owned thermal power plant in Kahalgaon, Bihar will install bagging machines for its fly-ash production. The facility provides fly-ash to cement makers in the northeast and is setting up six packing machines filling a total of 4800bags/hr or 4000t/day. The facility had been warned by the pollution control board, which has asked NTPC to deposit US$16,243 as security against the prescribed environmental measures. The board has said that the plant will be closed if it continues to violate the 'norms' by open-filling the sacks.
Tata Power may export fly ash to West Asia
09 July 2014Qatar: Four Qatari companies have shown interest in buying fly ash from Tata Power, which operates a 4000MW plant in Mundra, Gujarat, India. The plant consumes about 40,000t/day of imported coal and generates around 1600t/day of fly ash. Currently two cement makers in Gujarat and one from Rajasthan collect 100 – 200t/day of fly ash from the Mundra plant.
Shree Cement to set up grinding plant in Odisha
11 June 2014India: Shree Cement plans to set up a 3Mt/yr cement grinding plant at Odapada in Dhenkanal District, Odisha State for about US$76.6m. The location will enable the cement maker to utilise the fly ash produced at the power plants owned by Lanco Badband Power, GMR Kamalanga, Navabharat Ventures and Bhushan Steel based in the region. The plant will be built on an area covering 0.24km2 of land which will be allotted by the district administration on Odisha Industrial Infrastructure Development Corporation's request.
Nippon Paper to sell fly ash
28 May 2014Japan: Nippon Paper Industries has announced that it will jointly launch a new project with Zerotechno, located in Oita city, to produce and sell fly ash to the cement industry. Both companies will establish the Nippon Paper Zerotechno Tohoku limited liability partnership on 1 July 2014, which is to be based at the site of Nippon Paper Ishinomaki Mill in Ishinomaki city, Miyagi prefecture. The purpose of the project is to contribute to restoration of Tohoku district from the earthquake disaster by expanding use of carbon-free fly ash derived from coal ash that coal-fired boilers emit at Ishinomaki Mill.
US: Titan America has announced that it has recently formed ST Equipment & Technology LLC (STET), in order to further expand the development of its separation technology in fly ash and mineral applications worldwide. STET will be based in Needham, Massachussetts, US.
Mike Allen, who recently joined the Titan family of businesses, will serve as STET's President. His experience spans 30 years in international mining and minerals equipment and operations, most recently as Komatsu America Corp's Vice President of International Sales. He reports to current Titan America CEO, Aris Papadopoulos, who will become STET's Executive Chairman on 1 August 2014.
Chile: Chile-based utility company E-CL and Cementos Bío Bío's Antofagasta plant have signed a contract that is related to the reuse of fly ash for cement production.
After a long process of development and testing between the two companies, the ash that is captured by filters from the central generating units Thermal Andina (CTA) and Thermal Power Hornitos (CTH) in Mejillones, is used to replace natural pozzolan in Cementos Bío Bío's cement products.
Cementos Bío Bío expects to consume 70% of the daily production of fly ash from the CTA and CTH generating units. The project will bring a huge environmental benefit, since prior to this agreement, all the ash was deposited in landfills. The ash is a non-hazardous waste with similar properties to natural pozzolan, so its use in place of pozzolan means that the cement maintains its durability and strength.
Carlos Ferruz, manager of generation sites and E-CL, said that, "This initiative gives a new use for the ash, incorporating this non-hazardous waste as a raw material to a useful product such as cement. Loading, transport and unloading is performed without generating pollution." Ferruz added, "Usually the ash resulting from electricity generation is taken to a landfill, but with this innovation the ash acquires a new use and proves to be a real contribution to the environmental sustainability policies of both companies."

Cementa to sell fly ash cement by 2015
16 October 2013Sweden: Cementa is developing a new cement that uses fly ash for sale by 2015. The project is part of the Swedish subsidiary of HeidelbergCement's drive to reduce its carbon emissions by 2030 and to meet the growing environmental requirements of its customers.
"We see this as a natural further step in our vision of zero carbon emissions by 2030," said Fredrik Jansson, Vice President and Marketing Director at Cementa.
Australia Cement broke competition law with fly ash contract
10 September 2013Australia: Australia Cement has been found in breach of Australian competition for a fly ash contract that lessened competition. As reported by The Australian newspaper, Justice Andrew Greenwood of the Federal Court in Brisbane made the verdict in a case against the cement producer by the Australian Competition & Consumer Commission (ACCC).
The ACCC had alleged that Cement Australia had breached the abuse of market power provision though a fly ash contract with Millmerran Power Partners. While finding no breach of section 46 of the Act, Justice Greenwood said Cement Australia had breached section 45 through a contract to buy the fly ash from the power station.
Only interim declarations were publicly released to give the parties the chance to go through the about 500-page judgment in case of any confidentiality issues. Justice Greenwood reserved his decision on costs and no decision was made on any penalties.
