An owner or contractor who removes lead paint from a steel bridge shall use the paint removal and containment methods required in parts 7025.0260 to 7025.0300, except that paint removal conducted only for the purpose of coatings analysis is exempt. Pollution control must be used on a bridge or other structure that traverses a state boundary, as if the bridge or structure were entirely in Minnesota, unless the owner or contractor complies with requirements of the neighboring state or province that are more restrictive in preventing lead contamination than those in parts 7025.0260 to 7025.0300.
The owner or contractor who uses dry abrasive blasting for surface preparation after removing all lead paint with any other method shall use the containment methods required in part 7025.0270, subparts 2 and 3, except that the use of curtains is not required if:
a low-dust nonsilica abrasive is used;
the total area of surface preparation is less than 1,000 square feet;
the bridge or bridge portion is class I or class II, or it is class III or class IV due to proximity of industrial or agricultural property only; and
particulate matter does not cross the owner's property line.
