Buzzi Unicem plants receive Energy Star certification
16 January 2017US: The Environmental Protection Agency (EPA) has awarded its Energy Star certification to four of Buzzi Unicem’s cement plants. Plants at Chattanooga in Tennessee, Festus in Missouri, Maryneal in Texas and San Antonio in Texas have all received the certification. It is awarded to cement plants that score 75 or above on the Energy Performance Indicator (EPI), used by the EPA to measure energy efficiency. In addition, the plant must have a three-year history of environmental compliance. The Chattanooga, Festus, and Maryneal plants have received the certification eight consecutive years in a row.
Cemex to cut emissions at five plants in US
28 July 2016US: The Environmental Protection Agency (EPA) and the Department of Justice (DOJ) have agreed a settlement with Cemex, under which the company will invest approximately US$10m to cut air pollution at five of its cement plants to resolve alleged violations of the Clean Air Act. Under the consent decree lodged in the District Court for the Eastern District of Tennessee, Cemex will also pay a US$1.69m civil penalty, conduct energy audits at the five plants, and spend US$150,000 on energy efficiency projects to mitigate the effects of past excess emissions of nitrogen oxides (NOx) from its facilities.
“This settlement requires Cemex to use state-of-the-art technology to reduce harmful air pollution, improving public health in vulnerable communities across the South and Southeast,” said Cynthia Giles, Assistant Administrator for EPA’s Office of Enforcement and Compliance Assurance. “EPA is committed to tackling clean air violations at the largest sources, cutting the pollutants that cause respiratory illnesses like asthma.”
The five Cemex cement plants affected by the deal are located in Demopolis in Alabama, Louisville in Kentucky, Knoxville in Tennessee and New Braunfels and Odessa in Texas. The Knox County, Tennessee and Louisville, Kentucky air pollution control authorities participated in this settlement. Cemex is required to install pollution control technology that will reduce emissions of NOx and establish strict limits for sulphur dioxide (SO2) emissions. The cement producer will install and continuously operate a selective non-catalytic reduction system for controlling NOx at the five plants and meet emission limits that are consistent with the current best available control technology for NOx. EPA estimates this will result in NOx emissions reductions of over 4000t/yr. Each facility will also be subject to strict SO2 emission limits.
This settlement is part of EPA’s National Enforcement Initiative to control harmful emissions from large sources of pollution, which includes cement plants, under the Clean Air Act’s Prevention of Significant Deterioration requirements. The total combined SO2 and NOx emission reductions secured from cement plant settlements under this initiative will exceed 75,000t/yr once all the required pollution controls have been installed and implemented.
The settlement is subject to a 30-day public comment period and final court approval.
Environmental Protection Agency calls for two cement plants in Pakistan to stop production
24 June 2016Pakistan: The Environmental Protection Agency (EPA) has issued directives to the Hazara and Kohat administrations to stop production at two cement plants in breach of EPA regulations on dust pollution. Muhammad Bashir Khan, the director general of the EPA, has issued directives to shut down the Dewan Hattar Cement plant in Hattar and the Kohat Cement plant, according to the News International newspaper. Khan said that the Dewan Hattar plant had requested an eight-month period to install dust control measures but had failed to do so. The Kohat plant’s dust control unit is currently out of order.
Argos Newberry cement plant gains Energy Star certification
25 February 2016US: The Argos USA Newberry cement plant in Florida has achieved Energy Star certification from the US Environmental Protection Agency (EPA) for its superior energy performance in 2015. It joins nine manufacturing plants that have gained the certification for the first time. Overall, 28 cement plants gained certification in 2015.
“Energy Star certified manufacturing plants are driving the kinds of efficiencies and innovations that keep our country strong,” said EPA Administrator Gina McCarthy. “They’re proving every day that businesses can save on energy, cut down on bills and reduce harmful greenhouse gas emissions all at the same time.”
Since 2006, the EPA has certified manufacturing plants with the Energy Star for reaching the top 25% of energy performance in their industries nationwide each year. Energy Star certified plants must have their energy performance independently verified. Plants from the automotive, cement manufacturing, corn refining, food processing, glass manufacturing, pharmaceutical manufacturing and petroleum refining industries are among those that qualified in 2015.
Since the inception of EPA’s Energy Star certification, a total of 148 manufacturing plants have achieved this distinction. These plants have saved over 41Mt million of carbon dioxide equivalent emissions.
EPA settles major air pollution case with Cemex in Puerto Rico
05 October 2015Puerto Rico: The US Environmental Protection Agency (EPA) has announced that Cemex de Puerto Rico will spend US$1.7m on pollution controls that will reduce emissions of nitrogen oxides. In addition, the company will pay a US$160,000 penalty for Clean Air Act violations.
"Nitrogen oxides emissions can lead to a number of serious health and environmental problems, including respiratory problems, heart disease and smog," said Judith A Enck, EPA regional administrator. "The EPA settlement protects children with asthma and other vulnerable populations from harmful air pollution by requiring that Cemex install state-of-the-art technology and take immediate steps to reduce pollutants."
The Cemex cement kiln system in Ponce has operated for over 20 years and is a major source of nitrogen oxide emissions. The settlement addresses modifications Cemex made to its cement plant without obtaining the proper permit, as required by the Clean Air Act. Businesses that produce large quantities of air pollution are required to obtain permits and install pollution control technology before making changes that would significantly increase emissions.
Following an EPA inspection, Cemex conducted a smokestack test at its Ponce facility and potential violations were discovered. In the settlement, Cemex will install control technology, which will reduce emissions of nitrogen oxides by approximately 1423t/yr.
US: Holcim (US), part of LafargeHolcim, has announced that five of its plants earned the US Environmental Protection Agency's (EPA) prestigious Energy Star.
"We are pleased that the EPA has recognised Holcim's continued commitment to environmentally sound practices by awarding five of our plants with the Energy Star Award," said John Stull, chief executive officer of Holcim (US). "Sustainability is a core component of our values and a priority for our employees at every plant and facility."
This marks the fourth time Holcim's Portland plant in Florence, Colorado and the Midlothian plant in Midlothian, Texas have received the award, while the Devil's Slide plant in Morgan, Utah has been honoured for its eight consecutive year. The Holly Hill plant in Holly Hill, South Carolina and the Ste. Genevieve plant in Bloomsdale, Missouri are both receiving the award for the sixth time.
St. Marys Cement plant in Dixon looking to reopen
27 November 2014US: The mayor of Dixon, Illinois says that he is 'optimistic' that the mothballed St. Marys cement plant in the city will reopen. Mayor Jim Burke told local press that representatives from St. Marys Cement approached him in mid-2014 to discuss the possibility of restarting operations at the plant. The mayor says that the city government is working with the company to see if there are incentives 'to make it all work.'
The plant has been idle since December 2008. When it closed about 90 people lost their jobs. At the same time the Environment Protection Agency fined the company and a co-owner for violations of the Clean Air Act. St. Marys Cement is owned by Brazilian-based cement producer Votorantim.
US: Holcim has broken ground on the two-year US$95m modernisation project of its Hagerstown, Maryland cement plant. The project is expected to reduce the plant's environmental footprint and create hundreds of construction jobs in the process.
In addition to creating between 200 and 300 construction jobs during peak construction, Hagerstown plant manager Fernando Valencia said that the plant modernisation will decrease NOx emissions by an estimated 60% and SO2 emissions by about 48%. The project includes shortening the plant's existing rotating kiln, installing a new preheater tower over the top of the remaining kiln and installing an energy-efficient clinker cooler to replace the existing one, according to Holcim spokeswoman Robin DeCarlo.
The project comes after Holcim was hit with federal Clean Air Act violations from the US Environmental Protection Agency (EPA) in 2013. Holcim and the plant's former owner, St Lawrence Cement, agreed to a settlement with the EPA and planned to invest US$20m or more to upgrade the Hagerstown plant to significantly reduce NOx and SO2 emissions. The settlement, which was reached in July 2013, required Holcim to reduce SO2 emissions by 230t/yr and NOx emissions by 92t/yr by 9 September 2016. That would limit the SO2 emissions to 655t/yr and 0.82kg (1.8lb) of NOx per 0.89t (1 short ton) of clinker produced.
Wyanga Holdings settles out of court for exceeding extraction limits
02 December 2013Australia: Wyanga Holdings, Australian quarry specialists, has settled out of court after it was taken before the Land and Environment Court for exceeding its extraction limits.
Wyanga Holdings, the New South Wales Roads and Maritime Services Department (RMA) and the Environment Protection Agency (EPA) were set to appear before Justice Sheahan at the NSW Land and Environment Court on 27 November 2013. However, Wyanga Holdings withdrew its appeal on the day over its Corindi Quarry licence issues and agreed to pay costs to the EPA and RMS in the appeal.
In August 2013 the EPA suspended Wyanga Holdings' licence for the quarry for seriously breaching the extraction limits on its license. Wyanga had extracted more than 368,000t of aggregate despite the extraction limit of 50,000t/yr.
Wyanga Holdings will now have to lodge a development application with Coffs Harbour City Council for consent to operate the quarry in excess of its original licence. The council rejected an earlier application.
ESSROC and EPA waste unit dispute deferred until February 2014
12 November 2013US: Lawyers for the Environmental Protection Agency (EPA) and ESSROC are in talks to settle a legal dispute pending before the Environmental Appeals Board (EAB). The EAB had scheduled the case for 7 November 2013 but on 6 November 2013 EAB Judge Leslye Fraser stayed the case until 20 February 2014 to allow time for settlement talks. The order requires ESSROC and EPA's Region V to report to the EAB on the status of negotiations by 9 January 2014.
The case began 8 July 2013 when the ESSROC Cement Corporation petitioned the EAB to review Region V's decision requiring an SSRA at ESSROC's hazardous waste combustor facility in Logansport, IN, during the 2012 renewal of the facility's Resource Conservation and Recovery Act (RCRA) permit. In a 25 September 2013 order, the EAB granted oral argument in the case, and asked that during the proceedings the two sides revisit arguments from industry's past challenge to a 2005 EPA rule setting maximum achievable control technology (MACT) standards under the Clean Air Act for the combustion facilities.
