It details permissible levels and averaging periods for various pollutants, including Nitrogen Dioxide (NO2), Particulate Matter (PM10 and PM2.5), Sulphur Dioxide (SO2), and Carbon Monoxide (CO). For each pollutant, the document specifies the Annual Mean, Hourly Mean, Daily Mean, 15-minute mean, 1-hour, 24-hour, and Running 8-hour average values, along with their corresponding Maximum Permitted Exceedances per year. This framework serves as a critical reference for technical assessments and policy implementation concerning air quality
