To determine the required reductions in SO2 and PM10 to be compliant with NAAQS and NSPS and ultimately comply with the Clean Air Act, we need to consider the relevant standards and regulations.
1. NSPS (New Source Performance Standards):
The NSPS sets the emission standards for new, modified, and reconstructed stationary sources, including power plants. In this case, the power plant is planned to have a raw pollution rate of 4 times the NSPS for SO2 and 10 times the NSPS for PM10.
We need to find the NSPS for SO2 and PM10 to determine the maximum allowable emissions according to the NSPS standards. The NSPS for different pollutants can be obtained from the relevant regulatory authorities or environmental agencies.
2. NAAQS (National Ambient Air Quality Standards):
The NAAQS sets the maximum allowable concentrations for various air pollutants in the ambient air. In this case, we need to focus on the NAAQS standards for PM10.
Given that the region where the power plant is to be built is already in non-attainment for PM10, with a 24-hour mean concentration of 200 μg/m3, we need to determine the NAAQS for PM10 to understand the maximum allowable concentration of PM10 in the air.
We can obtain the NAAQS for PM10 from the relevant regulatory authorities or environmental agencies.
3. Compliance with the Clean Air Act:
The Clean Air Act is a federal law in the United States that sets the framework for reducing air pollution and maintaining air quality. Compliance with the Clean Air Act involves meeting the standards set by the NSPS and NAAQS.
To determine the required reductions in SO2 and PM10, we need to compare the planned emissions from the new power plant with the maximum allowable emissions according to the NSPS standards for SO2 and PM10.
Then, we need to compare the current PM10 levels (200 μg/m3) with the NAAQS for PM10 to determine the required reductions in PM10 to comply with the NAAQS.
It is important to note that specific values for NSPS and NAAQS standards are not provided in the question. The actual calculations for required reductions would require the specific values for NSPS and NAAQS standards for SO2 and PM10.
