Real-time sampling maps
Maps are displayed for each day of sampling activity to be representative of the areas in which samples were taken. Samples were taken from the perimeters of the site as well as the work areas. Reference to the real-time sampling tables identify which samples were taken in the work areas as opposed to site perimeters or community.
Real-time sampling Charts
This is a graphical representation of the real-time samples against the National Ambient Air Quality Standard of .15 mg/m3. Any points with a reading over the National Ambient Air Quality Standard of 0.15 mg/m3 are plotted on the chart. Explanations for any samples taken above the National Ambient Air Quality Standard can be obtained by reading the comment section from the applicable sampling table. Sampling tables and charts are sorted according to the day the samples were taken.
Real-time sampling Tables
These are tables created each day to display the actual results with technician comments. All average daily results were below 0.050 mg/m3 for dust. The National Ambient Air Quality Standard is 0.15 mg/m3. Any points with a reading over the National Ambient Air Quality Standard of .15 mg/m3 will be highlighted in the table.
