19 CSR 30-70.600 - Definitions Pertaining to the Work Practice Standards for Conducting Lead-Bearing Substance Activities

PURPOSE: This rule provides definitions and acronyms to be used in the interpretation and enforcement of 19 CSR 30-70.600 through 19 CSR 30-70.640.

(1) Adequate quality control-a plan or design which ensures the authenticity, integrity, and accuracy of samples, including dust, soil, and paint chip or paint film samples. Adequate quality control also includes provisions for representative sampling.
(2) Authorized personnel-licensed lead workers, licensed lead risk assessors, licensed lead supervisors, licensed lead contractors, licensed project designers, representatives of the department and any persons authorized by the department to enter regulated areas.
(3) Bare soil area-any continuous three (3) square foot area or more of soil that has no or little plant growth or other covering, and that may be accessible to a child or may provide a source of airborne lead-bearing dust, including the sand in sandboxes.
(4) Clearance level-values that indicate the maximum concentration of lead allowed in surface dust, soil or water following an abatement activity.
(5) Common area-a portion of a building that is generally accessible to all occupants including, but not limited to, hallways, garages, laundry rooms, community centers, boundary fences, stairways, playgrounds and recreational rooms.
(6) Component or building component-a specific design, structural element or fixture of a building, dwelling or child-occupied facility that can be distinguished from each other by form, function and location.
(7) Containment-the structural system for protecting residents, the general public and the environment by controlling exposure to lead dust and debris created during a lead abatement project.
(8) Critical barrier containment-two (2) or more layers of six (6)-mil poly, or thicker, sealed over the entrance into a work area to prevent lead dust and debris from migrating outside of a regulated area.
(9) Disposal-the depositing or placing of lead-bearing components or a lead-bearing substance as waste.
(10) Distinct painting history-the application history, as indicated by its visual appearance or a record of application, over time, of paint or other surface coatings to a component or room.
(11) Documented methodologies-methods or protocols used to sample for the presence of lead in paint, dust, soil and water while incorporating adequate quality control.
(12) Elevated blood lead level (EBL)-an excessive absorption of lead that is a confirmed concentration of lead in whole blood of greater than or equal to ten micrograms per deciliter (>=10 [MICRO]g/dl) in persons under age eighteen (<18).
(13) Emergency situation-any lead abatement project that results from a sudden, unexpected event which poses an immediate threat to human health or the environment.
(14) EPA-United States Environmental Protection Agency.
(15) Hazardous waste-any waste designated as hazardous by 10 CSR 25-4.261 and/or 40 CFR 261.
(16) High efficiency particulate air (HEPA) filter-a filter capable of removing particles of 0.3 microns or larger from air at 99.97 percent or greater efficiency.
(17) HUD-United States Department of Housing and Urban Development.
(18) HUD guidelines-the most recent version of the "Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing," published by HUD.
(19) Industrial lead abatement-a lead abatement project performed on a structure not defined as a dwelling or child-occupied facility which includes, but is not limited to, bridges, water towers, holding tanks and other superstructures. Industrial lead abatement does not include abatement of a de minimis surface area of less than fifty (50) square feet of a lead-bearing substance per lead abatement project.
(20) Intact paint surface-any painted surface that is not chipped, chalked, peeled, flaked or otherwise separated from its substrate or that is not attached to a damaged substrate.
(21) Lead hazard screen-a risk assessment activity that involves limited paint and dust sampling as described in 19 CSR 30-70.620(7).
(22) Living area-any area of a residential dwelling used by one (1) or more children age six (6) and under, including, but not limited to, living rooms, kitchen areas, dens, play rooms and children's bedrooms.
(23) Multi-family dwelling-a structure that contains more than one (1) separate residential dwelling unit, which is used or occupied, or intended to be used or occupied, in whole or in part, as the home or residence of one (1) or more persons.
(24) NLLAP-National Lead Laboratory Accreditation Program.
(25) OLLA-Missouri Department of Health Office of Lead Licensing and Accreditation, or subsequent designations of such office.
(26) Permanent-an activity that is designed to eliminate exposure to lead hazards for at least twenty (20) years, under typical conditions, from the date of application.
(27) Poly-polyethylene sheeting.
(28) RCRA-Resource Conservation and Recovery Act.
(29) Regulated area-an area where a lead-bearing substance activity is being conducted.
(30) Room equivalent-an identifiable part of a residence, such as a room, a house exterior, a foyer, staircase, hallway or an exterior area (i.e., play areas, painted swing sets, painted sandboxes, etc.).
(31) Structural integrity-a professional judgment as to the condition of a substrate, component or structure itself.
(32) Substrate-a surface to which a surface coating has been or may be applied. Examples of substrates are wood, metal, plaster, gypsum, concrete and brick.
(33) Surface coating integrity-a professional judgment as to whether a surface coating is cracked, chipped, peeling, blistering, flaking or otherwise deteriorated in any way.
(34) Surface coatings-include, but are not limited to, paints, stains, lacquers, varnishes and shellacs.
(35) Target housing-a dwelling built prior to 1978.
(36) Testing combination-a unique combination of a room equivalent, building component type and substrate.
(37) TSCA-Toxic Substances Control Act.
