- BEIJING, China (CNN) -- Chinese officials announced an emergency plan to deal with Beijing's persistent pollution problem, as thousands of world-class athletes head toward the country for the start of the Olympic Games.
The measures would be implemented if forecasters see stagnant weather conditions 48 hours in advance.
The Chinese Environmental Ministry drafted the plan in conjunction with the cities of Beijing and Tianjin and Hebei province.
A draconian plan announced last week closed down a number of factories, shut down all outdoor construction sites and decreed that drivers could be on the roads based on their license plate number -- odd numbers on one day, even numbers the next.
But the plan failed to make a dent, and the air quality got worse, shrouding the capital like a heavy fog, choking people and choking off the sunlight. Watch images of the city before and after the July 20 plan »
The emergency plan would close an additional 105 factories in Beijing and more than 106 others outside the city. The plan would further restrict driving by preventing vehicles from being in operation if the last digit of the license plate number corresponds with the day of the month.
The plan would also institute odd/even driving days for Tianjin city. Odd/even driving days would also be put into effect in Hebei province, but only between the hours of 7 a.m. and 10 p.m.
Wind and rain helped clear some of the gloomy gray haze on Tuesday, and meteorologists predicted that the Games, which begin on August 8 with the Opening Ceremony, would see cooler temperatures and less hazy skies.
A reading on Wednesday found that Beijing's pollution levels dropped by more than half over a 24-hour period to 44 on the index, the lowest reading since the July 20 plan took effect, according to The Associated Press. A reading below 50 is considered "good," AP reported, adding that a cooling wind and some rain helped sweep away pollutants.
The improvement in air quality reflects the effectiveness of those measures, AP cited Du Shaozhong, deputy director of Beijing's Environmental Protection Bureau, as saying.
Authorities, however, wanted to take no chances and announced the emergency plan.
The capital and surrounding areas of northeastern China have the world's worst nitrogen dioxide levels, according to satellite images taken by the European Space Agency in 2005.
The U.S. Environmental Protection Agency says the chemical can cause eye, nose, and throat irritation, and may cause impaired lung function and increased respiratory infections.
