Explanation: The Graded Response Action Plan (GRAP) is a comprehensive strategy designed to combat air pollution in Delhi. It includes a series of measures that are implemented based on the severity of pollution levels. The primary goal of GRAP is to reduce pollution from various sources, including industrial emissions, vehicular emissions, and construction activities.
One of the key measures under GRAP is the closure of the Badarpur thermal power plant. This plant was a significant source of pollution in Delhi, and its closure has had a substantial impact on reducing air pollution levels. The plant's operations were a major contributor to the city's air quality issues, and its shutdown aligns with the objectives of GRAP.
Another measure under GRAP is the ban on pet coke as a fuel in Delhi. Pet coke is a highly polluting fuel that is often used in industries and power plants. The ban on pet coke helps in reducing the overall pollution levels in the city by eliminating a significant source of emissions.
GRAP also includes the implementation of stricter fuel standards, such as bringing BS-I fuel to Delhi before the deadline. The use of cleaner fuel standards helps in reducing vehicular emissions, which are a major source of pollution in urban areas. The implementation of BS-I fuel standards is a direct measure under GRAP to improve air quality.
While reducing road dust pollution is an important environmental action, it is not a specific measure outlined under GRAP. Road dust pollution can be managed through various methods such as regular road cleaning, water sprinkling, and the use of dust suppressants. However, these actions are not part of the specific measures listed under GRAP.
In conclusion, the measures under GRAP are designed to address specific sources of pollution in Delhi. The closure of the Badarpur thermal power plant, the ban on pet coke, and the implementation of stricter fuel standards are all direct measures under GRAP. Reducing road dust pollution, while important, is not a specific measure under GRAP and is therefore the correct answer to the question.
