The case was flagged by the environment ministry in a notice issued on May 10, which said party officials in Bozhou lacked “political consciousness … the nature of this case is very severe”.
Watering down results
Environmental officials in Shizuishan, in the northwest region of Ningxia, tried to improve their results in December 2017 by ordering sanitation workers to spray the building of the local environmental protection bureau with an anti-smog water cannon.
The intention was to lower the amount of pollutant particles registered by the building’s monitoring equipment.
The scheme may have gone undetected if the weather had been warmer but the next day a telltale layer of ice covered the building and the chief and deputy chief of the environmental station in the city’s Dawokou district were later penalised for influencing the monitoring results.

Similar tactics were deployed in Linfen, in the northern province of Shanxi in March 2017, when former bureau chief Zhang Wenqing and 11 others were found to have altered air quality monitoring data during days of heavy pollution.
The monitoring machine was blocked and sprayed with water to improve the data and Zhang was also found to have paid another person to make sure the sabotage was not captured by surveillance camera.
According to the environment ministry, six national observation stations in Linfen were interfered with more than 100 times between April 2017 and March 2018. In the same period, monitoring data was seriously distorted on 53 occasions.
Zhang was sentenced to two years in prison in May last year for destroying information on a computer.
Bad company
A ministry notice on May 11 flagged collusion by local officials and businesses in Bozhou in southeast China’s Anhui province. Companies were given advance notice of environmental inspections, with instructions to make up contracts and temporarily suspend production in a bid to deceive inspectors.
In Henan province, central China, inspectors found a thermal power company had been using a wireless mouse to interfere with the sealed automatic monitoring system. They were able to remotely delete undesirable data, eliminating evidence of excessive emissions, and only provided selective data to the environment bureau.
Officials in Shandong reprimanded for failing to cut pollution
In another case, from 2017, an environmental inspection group in Hubei province, central China, found a ceramics company had been working with the data monitoring company to alter automatically collected data on sulphur dioxide emissions.
Criminal offence
Cao said that while the cheating by grass-roots officials was serious, the involvement of companies in falsifying data was a major issue that made the work of inspectors even harder.
“Some fraudulent methods are hidden with the help of high technology, so it’s hard for us to obtain evidence. Besides, the environment officials are not totally familiar with these technologies,” he said.
The environment ministry was working on solutions to the problems, he said, adding that falsifying monitoring data was now a criminal offence.
Fake data was particularly serious, he said, because it could directly influence his department’s decisions about where to deploy resources.
