Editor's note
As filed in O. Reg. 350/06, the first thickness-column heading of Table 9.23.14.5.A. reads 'Plywood and OSB, O-2 Grade' with a space between 'OSB,' and 'O-2'; the current e-Laws consolidation editorially removes the space, rendering it as the run-together 'Plywood and OSB,O-2 Grade', with no amending regulation making the change. This map preserves the as-filed spacing.
