Rule 641-69.2 - Definitions

"Arithmetic mean" means the algebraic sum of data values divided by the number of data values. For example, the sum of the concentration of lead in several soil samples divided by the number of samples is the arithmetic mean.

"Certificate of mailing" means certified mail with return receipt or its equivalent.

"Chewable surface" means an interior or exterior surface painted with lead-based paint that a young child can mouth or chew.

"Child-occupied facility" means a building, or portion of a building, constructed prior to 1978, that is described by all of the following: (1) The building is visited on a regular basis by the same child, who is less than six years of age, on at least two different days within any week. For purposes of this chapter, a week is a Sunday through Saturday period. (2) Each day's visit by the child lasts at least 3 hours, and the combined annual visits total at least 60 hours. A child-occupied facility may include, but is not limited to, a child care center, preschool, or kindergarten classroom. A child-occupied facility also includes common areas that are routinely used by children who are less than six years of age, such as restrooms and cafeterias, and the exterior walls and adjoining space of the building that are immediately adjacent to the child-occupied facility or the common areas routinely used by children under the age of six years. "Child-occupied facility" also includes any building where lead-based paint activities are conducted immediately prior to or during the conversion of the building to a child-occupied facility.

"Common area" means a portion of the building that is generally accessible to all occupants. This includes, but is not limited to, hallways, stairways, laundry and recreational rooms, playgrounds, community centers, garages, and boundary fences.

"Compensation" means payment or reimbursement for services performed. Compensation is not limited to monetary considerations and includes payment of rent for rental units, receipt of a salary from the owner or manager of target housing, and receipt of a salary from the owner or operator of a child-occupied facility.

"Components" means specific design or structural elements or fixtures of a building, residential dwelling, or child-occupied facility that are distinguished from each other by form, function, and location. These include, but are not limited to, interior components such as ceilings, crown moldings, walls, chair rails, doors, door trim, floors, fireplaces, radiators and other heating units, shelves, shelf supports, stair treads, stair risers, stair stringers, newel posts, railing caps, balustrades, windows and trim (including sashes, window heads, jambs, sills or stools and troughs), built-in cabinets, columns, beams, bathroom vanities, countertops, and air conditioners; and exterior components such as painted roofing, chimneys, flashing, gutters and downspouts, ceilings, soffits, fascias, rake boards, cornerboards, bulkheads, doors and door trim, fences, floors, joists, latticework, railings and railing caps, siding, handrails, stair risers and treads, stair stringers, columns, balustrades, windowsills or stools and troughs, casing, sashes and wells, and air conditioners.

"Department" means the department of public health.

"Dripline" means the area within three feet surrounding the perimeter of a building.

"Dust-lead hazard" means surface dust in residential dwellings or child-occupied facilities that contains a mass-per-area concentration of lead equal to or exceeding 10 micrograms per square foot on floors, 100 micrograms per square foot on interior windowsills, and 400 micrograms per square foot on window troughs based on wipe samples. A dust-lead hazard is present in a residential dwelling or child-occupied facility when the weighted arithmetic mean lead loading for all single-surface or composite samples of floors and interior windowsills is equal to or greater than 10 micrograms per square foot on floors, 100 micrograms per square foot on interior windowsills, and 400 micrograms per square foot on window troughs based on wipe samples. A dust-lead hazard is present on floors, interior windowsills, or window troughs in an unsampled residential dwelling in a multifamily dwelling if a dust-lead hazard is present on floors, interior windowsills, or window troughs, respectively, in at least one sampled residential unit on the property. A dust-lead hazard is present on floors, interior windowsills, or window troughs in an unsampled common area in a multifamily dwelling if a dust-lead hazard is present on floors, interior windowsills, or window troughs, respectively, in at least one sampled common area in the same common area group on the property.

"Dwelling unit" means a single, unified combination of rooms designed for use as a dwelling by one family.

"Emergency renovation, remodeling, or repainting" means renovation, remodeling, or repainting activities necessitated by nonroutine failures of equipment or a structure that were not planned but resulted from a sudden, unexpected event that, if not immediately attended to, presents a safety or public health hazard or threatens equipment or property with significant damage.

"Friction surface" means an interior or exterior surface that is subject to abrasion or friction including, but not limited to, certain window, floor, and stair surfaces.

"Hazardous lead-based paint" means lead-based paint that is present on a friction surface where there is evidence of abrasion or where the dust-lead level on the nearest horizontal surface underneath the friction surface (e.g., the windowsill or floor) is equal to or greater than the dust-lead hazard level, lead-based paint that is present on an impact surface that is damaged or otherwise deteriorated from impact, lead-based paint that is present on a chewable surface, or any other deteriorated lead-based paint in any residential building or child-occupied facility or on the exterior of any residential building or child-occupied facility.

"Housing for the elderly" means retirement communities or similar types of housing reserved for households composed of one or more persons 62 years of age or older or an age recognized as elderly by a specific federal housing assistance program.

"Impact surface" means an interior or exterior surface that is subject to damage by repeated sudden force such as certain parts of door frames.

"Lead-based paint" means paint or other surface coatings that contain lead equal to or in excess of 1.0 milligram per square centimeter or more than 0.5 percent by weight.

"Lead-based paint hazard" means hazardous lead-based paint, a dust-lead hazard, or a soil-lead hazard.

"Living area" means any area of a residential dwelling used by at least one child six years of age or less including, but not limited to, living rooms, kitchen areas, dens, playrooms, and children's bedrooms.

"Mid-yard" means an area of a residential yard approximately midway between the dripline of a residential building and the nearest property boundary or between the driplines of a residential building and another building on the same property.
