Houston County opens civil suit against Sesco for alleged unlawful piles

08 January 2020

US: The attorney’s office of Harris County in Texas filed a lawsuit against Sesco for alleged public safety and environmental violations following multiple complaints to the Harris County Pollution Control Board about dust. Piles of debris in an outdoor area of Sesco’s Houston cement terminal may have caused high dust levels in and around the facility and high pH levels in water located nearby. Houston Business Journal conjectured that the stockpiles might consist of surplus cement being stored unlawfully. Sesco stands accused of operating two silos and three hoppers without proper environmental clearance. Inspections in 2019 uncovered set cement in storm drains at the facility.

Zuari Cement’s Sitapuram plant breaches particulate matter emissions

19 July 2019

India: Zuari Cement’s integrated cement plant at Sitapuram, Telangana has been issued a show cause notice by the Central Pollution Control Board (CPCB) for exceeding particulate matter emissions. During an inspection it has found to be emitting 40.6mg/Nm3 from the kiln and 78mg/Nm3 from the cement mill, according to the Times of India newspaper. The limit is 30mg/Nm3. CPCB officials also found other violations including an alleged deliberate attempt show reduced levels of sulphur dioxide and nitrogen oxide. The plant has been asked to calibrate its dust monitors properly and submit a compliance report by late July 2019.

Chettinad Cement’s Karikkali plant breaches particulate matter emissions

18 July 2019

India: Chettinad Cement’s Karikkali plant in Tamil Nadu has been issued a show cause notice by the Central Pollution Control Board (CPCB) for exceeding particulate matter emissions by more than three times the limit. An inspection following Online Continuous Emission Monitoring Systems (OCEMS) data found emissions of 91.2mg/Nm3, according to the New Indian Express. The limit is 30mg/Nm3. The CPCB also found discrepancies with the OCEMS data due to poor instrument calibration.

PPC to shut kiln at Port Elizabeth cement plant due to new emissions standards

02 July 2019

South Africa: PPC says it plans to shut the kiln at its Port Elizabeth cement plant ahead of stricter requirements to the country’s emission standards. It is shutting down the kiln to meet new standards for NO2 and dust emissions on 1 April 2020, according to Reuters. Around 30 jobs are expected to be affected by the shutdown.

The cement producer’s revenue rose slightly year-on-year to US$736m in its financial year to 31 March 2019. Its profit nearly quadrupled to US$10.2m. Its cement sales volumes also rose slightly to 5.9Mt. Sales and earnings fell in South Africa due to a poor market but they grew elsewhere in Sub-Saharan Africa, notably in Rwanda and the Democratic Republic of Congo.

Dust matters in India

12 June 2019

There was a glimmer of good news visible through the Delhi smog this week with the launch of a market-based emissions trading scheme (ETS) for particulate matter (PM). A pilot has started at Surat in Gujarat. The scheme will apply to 350 industries in the locality and it will be scrutinised for wider rollout in the country.

China robustly started to tackle its industrial PM emitters a few years ago although the work remains on-going. In its wake India has increasingly made the wrong sort of headlines with horrifically high dust emissions. Delhi, for example, reportedly had PM2.5 emissions of over 440µg/m3 in January 2019. To give this some context, the World Health Organisation’s (WHO) annual upper guideline figure for safe human exposure is 10µg/m3. Research by the Financial Times newspaper suggested that more than 40% of the Indian population is subject to annual PM2.5 emissions of over 50µg/m3.

Air Quality Life Index (AQLI) research reckons that if India were able to meet its national PM2.5 standard of 40µg/m3 then its population would live 1.8 years longer or 4.3 years longer if it met the WHO guideline level. The current situation is an unnecessary tragedy. In strictly structural terms the country’s productivity is being thrown away by damaging the health of its workforce. For comparison amongst other major cement producing countries, AQLI data placed China’s PM2.5 emissions at 39µg/m3, Indonesia at 22µg/m3, Vietnam at 20µg/m3 the US at 9µg/m3. These figures cover all industries in different conditions and climates. If the US can do it, why not the others?

Back on trading schemes, the famous ETS at the moment is the European one for CO2 emissions. Similar schemes are slowly appearing around the world as governments look at what the European Union (EU) did right and wrong. For example, South Africa started up a carbon tax in early June 2019. Yet as the supporting documents by the Gujarat Pollution Control Board (GPCB) point out there have been a variety of ETS systems’ over the years. The US’s Acid Rain Program is generally seen to have achieved significant reductions in SO2 and NOx emissions although the National Emission Standards for Hazardous Air Pollutants (NESHAP) has continued this work. Chile even ran its own PM ETS in the 1990s although the outcomes have been disputed.

One problem with a CO2 ETS, and anthropomorphic or man-made climate change in general, is that it is intangible. Even if sea levels deluge major coastal cities, rising mean temperatures reduce agricultural yields and human populations contract sharply, people will still be arguing over the research and the causes. The beauty of a PM ETS is that if it works you can literally see and feel the results. A famous example here is the UK’s Clean Air Act in the 1950s that banished the fog/smog that London used to be famous for.

The Gujarat PM ETS is a pilot, the results of which will be considered by researchers from a number of US-based universities and the Abdul Latif Jameel Poverty Action Lab. Explicitly, the study plans to use a randomised control trial to compares its results against the command and control style approach used in the rest of the country. On the cement-side various Indian news stories have emerged as state pollution boards have increasingly started fining producers for emission limit breaches. Clearly the government is taking dust emissions seriously. Reduction is long overdue.

Dust dispute for Buzzi in Monselice

26 March 2019

Italy: The Buzzi Unicem cement plant in Monselice, Padua has come under fire from concerned locals following an emission of dust on 25 March 2019. Local press reported that the plant failed to notify residents following an emission of raw meal for at least three hours and not until plant staff had been telephoned by the media.

The plant uses marl and supplementary raw materials, the alleged unclear origins of which have particularly animated local environmentalists. Environment Councilor and mayoral candidate Gianni Mamprin said, “They say it’s just dust, but I don’t trust them. A plant of this type is incompatible with the tourism project that we want to implement in Monselice. Above all, Article 19 of the Environmental Plan of the Colli Park states that (it) is an incompatible plant in a natural park. If I am elected mayor of Monselice, I will actively commit to the closure of this unhealthy plant, because this territory does not need a factory that continually creates anxieties and doubts for citizens.”
