China: According to data released by the Beijing Municipal Environmental Protection Bureau on 13 January 2013 one cement production line was suspended at the Beijing Cement Plant due to air pollution in Beijing. The move followed measurements of particulate matter smaller than 2.5μm (PM_2.5) over 900µg/m³ in several districts of the city on 12 January 2013, the highest level recorded since Beijing began publishing the data in early 2012. The World Health Organization considers the safe daily level to be 25µg/m³.

According to data released by the Bureau on 13 January 2013 in addition to the Beijing Cement Plant closure, 54 businesses in Beijing had cut their emissions by 30%, 28 construction sites had stopped foundation work and Beijing Hyundai Motor Co temporarily halted production. The smog also caused the cancellation of at least 25 international and domestic flights to and from Beijing Capital International Airport. Hospitals in Beijing and in the provinces of Hebei and Hubei have reported a rise in the number of patients with respiratory conditions during the period according to local media.

India: Villagers living near an ACC Cement plant in Orissa have accused the company of mismanaging its fly ash. According to the villagers living in Khaliapali, crops have been damaged by runoff fly ash created by a captive power plant at the nearby Bargarh cement plant. The resultant slurry has also spilled into the fields of the neighbouring villages of Banjibahali and Baragad.

Khaliapali villagers have accused ACC Cement of taking over 12 acres of land in the village and forcibly dumping fly ash on it despite protests. They said fly ash has become a nuisance in the village as it covers the houses and village water tank rendering water unfit for human use.

Additional District Magistrate Srinibas Kabi commented that the Regional Office of the Odisha State Pollution Control Board (OSPCB) had noted the villagers' concerns. However, OSPCB Regional Officer S S Mishra said they had not received any complaint from the Bargarh administration.

US: The Environmental Protection Agency (EPA) has approved a new measure meant to help approve US state Montana's levels of haze pollution. The signing follows widespread criticism by industry, conservationists and even other federal agencies.

The proposal aims to reduce emissions of sulfur dioxide and nitrogen oxides that cause haze. It details US$85m in upgrades needed at the state's major contributors of small particles that contribute to park haze, mainly at the Colstrip coal power plant. Holcim's cement plant near Three Forks requires selective non-catalytic reductions totalling US$1.32m to achieve annual NOx emissions reductions of 556t/yr. Ash Grove cement plant near Montana City requires selective non-catalytic reductions and low NOx burners totalling US$1.19 to achieve annual NOx emissions reductions of 1088t/yr.

Many of the commenters, including Holcim and Pennsylvania Power and Light, questioned the computer models used to calculate the effect of various technologies on emissions. Companies also complained that the EPA underestimated the costs required to retrofit their plants with new equipment. In response to a Holcim comment, the EPA decided that Holcim did not have to install lime injection and scrubbers because the reduction in emissions didn't justify the cost. The total price tag for Holcim was originally estimated at US$6.2m.

Under the Clean Air Act, the air in national parks and wilderness areas in the US is supposed to be as clean as possible. To achieve that goal, regional haze programmes in several states set pollution limits on industries. The goal is to restore visibility to natural conditions in national parks and wilderness areas from Idaho to North Dakota by 2064.

US: The US Environmental Protection Agency (EPA) appears poised to soften particulate matter (PM) limits in its pending revised air toxics rule for cement plants, while separately pursuing an extended compliance deadline for the rule. Both moves would represent major concessions to industry groups that sought a weaker rule but have the potential to rile environmentalists who say such changes would be unlawful.

According to an industry source, EPA will propose to soften the rule's PM limits on smokestacks for existing cement plants. New data submitted to EPA by the industry shows that the limit of 0.02kg/t of clinker set by the final rule prior to reconsideration is not realistically attainable. Instead, the EPA will probably revert to a higher number, closer to the 0.043kg/t that it offered in its original proposal.

Environmentalists oppose softening the air toxics rule and recently warned the agency in written comments that, "any changes diminishing or replacing the existing standards would be flatly unlawful." The likely changes to the rule follow a series of 11th-hour meetings that industry officials and others have held with EPA and White House Office of Management & Budget (OMB) staff seeking to shape the proposal.

The Portland Cement Association previously presented a paper to the EPA arguing for an increase in the emissions limit for PM. "The current PM limit of 0.02kg/t of clinker is very stringent," reported the paper. "Very few facilities can comply with the clinker limit without major investments in new and upgraded PM controls."

US: The Environmental Protection Agency (EPA) has sent for the White House Office of Management and Budget (OMB) to review its proposed revisions to its emissions rules for the Portland cement sector, ahead of a tentative 15 June 2012 deadline for issuing the revisions in line with a proposed consent decree with the industry.

The pending proposed revised rules undergoing OMB review will address not only the remand but also the EPA's May 2011 partial reconsideration of the cement rules - including standards for open clinker storage piles and start-up and shutdown monitoring requirements - as those provisions included in the recent proposed consent decree with industry.

In the Register notice on the consent decree, the EPA says that it "would also agree to propose to extend the existing source compliance date of 10 September 2013, or in any case to discuss the possibility of extending that date, and to take final action by 20 December 2012 regarding the date of compliance," if such provisions are 'supported by the administrative record.'

While stalling the compliance deadline would be a 'win' for the cement industry, it would likely draw protests from environmentalists supportive of the current air toxics rule. The deadline for comments on the proposed consent decree is 7 June 2012.

US: The Environmental Protection Agency (EPA) has agreed to delay maximum achievable control technology (MACT) air compliance for cement plants by two years. As part of on-going negotiations with the Portland Cement Association (PCA) if the EPA doesn't issues a proposal to this effect by 15 June 2012 then the PCA and other cement producers will be able to resume legal action against the pollution rulings.

Under the terms of a 16 April 2012 proposed consent decree, the EPA will have to issue by 15 June 2012 a proposal addressing a ruling on 9 December 2011 from the US Court of Appeals for the District of Columbia Circuit. The EPA's revisions will also have to cover separate pending industry administrative petitions. The EPA has been negotiating with the PCA over the terms of the proposed consent decree, following a ruling finding that the EPA failed to reconsider how a related incinerator emissions rule could potentially alter the cement rule's emission limits.

The EPA has also agreed under the proposed consent decree to finalise a revised MACT by 20 December 2012, but the settlement does not require that the agency finalise a two-year delay. Rather, the decree states that EPA must only include its 'final decision on whether to extend the compliance deadlines for existing sources' in the revised MACT.

The EPA and PCA also acknowledge that EPA must subject the agreement to public comment and review. The settlement further notes that, "if the federal government elects to withdraw or withhold consent to this Agreement" after considering public comments on it, "PCA shall have the right to withdraw from this Agreement and file a request to lift the abeyance requested by the Parties."

As environmentalists and states were not party to the settlement, this public comment would provide them with the first opportunity to challenge the possibility of a two-year delay for the rule's compliance deadline and changes to meet the other provisions in the settlement.

Dubai: Cement factories in Dubai face permanent closure if they fail to meet new green measures announced by the Ministry of Environment and Water.

In an advisory statement issued by Dr Rashid Ahmad Bin Fahd, Minister of Environment and Water, cement companies were warned that a temporary three-month closure may be issued to the 11 existing factories in the country if facilities were found in non-compliance. If problems identified in the first warning are not rectified within 90 days, the ministry could shut down an errant cement factory for good.

"In case of not removing violations within the period of administrative closure (three months), the ministry has the right to close the violating factory forever and withdraw its licence," state news agency WAM said.

New green measures aimed at improving air quality and workplace safety will apply not only to established production facilities but also to new cement plants, the ministry said. The ministry has called for cement companies to create new health, safety and environmental systems for all operations and to maintain ongoing records to monitor and follow up new measures.

One of the main thrusts of the resolution is to markedly reduce 'volatile dust emissions' created through concrete production. To achieve this, "cement factories are obliged to measure the amount of dust inhaled in ambient air," and send monthly reports for monitoring the quality of air and particles, in addition to the flue gas, to the Ministry and the competent authority. To keep dust from migrating into adjacent properties, cement factories have also been ordered to, "form a green belt around the plant" by covering external borders of the site with up to 50% of newly planted trees.

US: A proposed clean-up of Montana's air pollution by the Environmental Protection Agency (EPA) could cost nearby cement plants up to US$10m. Plans to improve visibility in public land, including Yellowstone and Theodore Roosevelt National Parks, would require upgrades within five years at the Ash Grove cement plant near Montana City and Holcim cement plant near Three Forks.

The EPA's action has been prompted partly by a legal challenge from environmentalists who sued the agency to set deadlines to follow through on haze rules adopted in 1999. Two of the groups involved, WildEarth Guardians and the Montana Environmental Information Center, said that the agency's proposal does not go far enough. Representatives of the groups criticised the EPA's rejection of even stricter pollution limits that would have required tens of millions of dollars in additional spending by the plants.

"People might gasp a little bit and say that's a lot of money but you have to look at how much these companies are profiting off these facilities. It dwarfs these costs," said Anne Hedges with the Montana Environmental Information Center.

The first phase of the EPA's program is aimed at plants built between 1962 and 1977 that churn out at least 250t/yr of pollutants. The goal is to eliminate haze in parks and wilderness areas by 2064. The cost of reducing haze across the US has been estimated at US$1.5bn/yr. Spin-off benefits from reduced health care spending on pollution-related illnesses were estimated at US$8.4bn/yr or more.

The proposal could become final after a 60-day public comment period. Public hearings in Montana hosted by the EPA are scheduled for 15 May 2012 in Helena and 16 May 2012 in Billings.
