16 Del. Admin. Code § 4459 § 2.0

The following words and terms, when used in this regulation, have the following meaning:

"Abatement" means any measure or set of measures designed to permanently eliminate lead-based paint hazards. Abatement includes:

The removal of lead-based paint and lead-contaminated dust, the permanent enclosure or encapsulation of lead-based paint, the replacement of lead painted surfaces or fixtures, and the removal or covering of lead-contaminated soil; and

All preparation, cleanup, disposal, and post-abatement clearance testing activities associated with these measures.

Specifically, abatement includes:

Projects for which there is a written contract or other documentation, which provides that an individual or firm will be conducting activities in or to a residential dwelling or a child-occupied facility that:

Shall result in the permanent elimination of lead-based paint hazards; or

Are designed to permanently eliminate lead-based paint hazards and are described in the first and second paragraphs of this definition.

Projects resulting in the permanent elimination of lead-based paint hazards, conducted by firms or individuals certified by the Secretary pursuant to Section 4.0 of this regulation, unless the projects are covered by the last paragraph in this definition.

Projects resulting in the permanent elimination of lead-based paint hazards, conducted by firms or individuals who, through their company name or promotional literature represent, advertise, or hold themselves out to be in the business of performing lead-based paint activities as identified and defined by this regulation unless the projects are covered by the last paragraph of this definition; or

Projects resulting in the permanent elimination of lead-based paint hazards that are conducted in response to State of Delaware or local abatement orders.

Abatement does not include renovation, remodeling, landscaping, or other activities when the activities are not designed 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. Furthermore, abatement does not include interim controls, operation and maintenance activities, or other measures and activities designed to temporarily, but not permanently, reduce lead-based paint hazards.

Abatement can also mean a method of remediation resulting in long-term or permanent removal of lead hazards (e.g., removing lead paint, replacing contaminated soil, or encapsulating surfaces), as defined by the U.S. Environmental Protection Agency (EPA) under the Toxic Substances Control Act (Public Law: Pub.
