(a) Homeowners performing lead abatement or interim abatement controls on their single unit owner-occupied housing are exempt from the requirements of this article: Provided, That the provisions of this section do not apply to any residential dwelling occupied by a person or persons other than the owner or the owner's immediate family as well as to any residential dwelling where a child with a documented elevated blood lead level resides.

(b) Abatement does not include renovation, remodeling, landscaping or other activities, when the purpose of such activities are not intended to permanently eliminate lead-based paint hazards, but, instead, are designed to repair, restore or remodel a given structure or dwelling, even though these activities may incidentally result in a reduction or elimination of lead-based paint hazards. Abatement also does not include interim controls, operations and maintenance activities, or other measures and activities designed to temporarily, but not permanently reduce lead-based paint hazards.

(c) The provisions of this article do not apply to lead-hazard reduction activities or to persons performing such activities when such activities are performed wholly within or on an industrial facility and are performed by persons who are subject to the training requirements of OSHA: Provided, That the provisions of this article do apply to any child-occupied building or area such as a child day care center located at an industrial facility.
