Diagrams
The labeled diagrams (files starting with diagram-) are drawn for this site. The sample counts come from 40 CFR 763.86, the notification thresholds and the friable categories from the federal asbestos NESHAP (40 CFR 61.141 and 61.145), and the North Dakota form from the NDDEQ asbestos program. They are not to scale and are not a survey of any particular building.
