Tianjin will implement ten measures to control ozone pollution during the summer, according to the Fresh Air Department.

High summer temperatures and strong sunlight intensify photochemical reactions in the atmosphere, causing nitric oxide and volatile organics to turn into ozone. This reaction causes an increasing concentration of ozone in the city. Ozone is increasingly becoming the major pollutant in Tianjin.

The city will launch special inspections and punish factories which over pollute, according to the environmental protection and management regulations.

In addition, the city will accelerate the management of volatile organics and rapidly improve the evaluation and renovation of the chemical engineering and petrochemical industries. Such measures will greatly reduce the emission of volatile organics into the atmosphere.

Moreover, the city will launch special provisions and inspections focused on coal firing facilities and nitric oxide emissions. The city will also manage the emissions of restaurants and kitchens. Tianjin will provide cleaning services to kitchens which have installed cooking purification facilities and ensure the stable operation of the facilities. Restaurants which have not installed such facilities must complete the installation no later than August 31.

Restuarants which complete the installation before August 31 will receive subsidies from the city. Those which finish after August 31 may receive 80 percent of the subsidies. Those which do not install the facilities will be completely forbidden to generate cooking fumes.

Furthermore, the city will start special regulations and inspections on automobile services. Painting in the open air will be strictly forbidden. Companies which have not installed management facilities for volatile organics will be forbidden to provide any services related to painting.

In addition, open-air barbeque places will be inspected, and open-air barbeques in major regions will be strictly forbidden.

Gas stations and oil storage will be strictly regulated and inspected. Any work relating to organic solvents, such as construction paintings, road lining, and handrail sprays will be completely forbidden from 1:00 to 5:00 in the afternoon everyday.
