If deteriorated painted surfaces or visible amounts of dust, debris or residue are present, these conditions must be eliminated prior to the continuation of the clearance procedures.
V.J.1.a.(ii) All surfaces in the work area are properly sealed and re-painted in accordance with Section V.I. (Coating and Sealing) of this Regulation Number 19, Part A, such that the surfaces are easily cleanable. These surfaces must be dry to the touch before the visual inspection and wipe sampling takes place.
V.J.1.a.(iii) All enclosure and encapsulation systems are properly installed, caulked and are dust tight in accordance with Sections V.G. (Encapsulation and Enclosure Requirements), and V.I. (Coating and Sealing) of this Regulation Number 19, Part A.
V.J.1.a.(iv) All areas adjacent to the work areas that were used as pathways to the work area are visibly free of lead-contaminated dust, debris or residue.
V.J.1.b. Following the visual inspection and any post-abatement cleanup required by Section V.J.1.a. (Visual Inspection) of this Regulation Number 19, Part A, clearance sampling for lead-contaminated dust and soil must be conducted. Clearance sampling may be conducted by employing single-surface sampling or composite sampling techniques.
V.J.1.c. Dust and soil samples for clearance purposes must be taken using documented methodologies that incorporate adequate quality control procedures.
V.J.1.d. Dust and soil samples for clearance purposes must be taken a minimum of 1 hour after completion of final post-abatement cleanup activities.
V.J.1.e. The following post-abatement clearance activities must be conducted as appropriate based upon the extent or manner of abatement activities conducted in or to the pre-1978 residential dwelling, or child-occupied facility:
V.J.1.e.(i) Clearance Sampling of Interior Abatement Projects
V.J.1.e.(i)(A) After conducting an abatement, at least one dust sample must be taken from one interior window sill and from one window trough (if available) and at least one dust sample must be taken from the floor of no less than four rooms, hallways or stairwells within the containment area. In addition, at least one dust sample must be taken from the floor outside the containment area and within 10 feet of containment where potential contamination is likely. If there are less than four rooms, hallways or stairwells within the containment area, then all rooms, hallways or stairwells must be sampled.
V.J.1.e.(ii) Clearance Sampling of Exterior Abatement Projects
V.J.1.e.(ii)(A) After conducting an exterior lead-based paint abatement, the following samples must be collected:
V.J.1.e.(ii)(A)(1) At least two dust samples must be collected from the work area if a paved surface or window are within the work area. At a minimum, one dust sample must be taken from one window (if any) and one dust sample must be collected from the floor of each patio, deck, driveway, or paved surface (if any) within the work area. Window samples must be collected from the window sill or window trough, alternating between rooms.
V.J.1.e.(ii)(A)(2) At least two composite soil samples must be collected from the soil within the work area. At a minimum, one composite soil sample must be collected from the soil along the building perimeter and one composite soil sample must be collected from the child's principle play area (if any in the work area). Each composite soil sample must consist of at least 5 and no more than 10 aliquots of soil from areas selected in accordance with documented methodologies.
V.J.1.e.(ii)(B) If the exterior abatement project involved only the covering or removing of bare soil then the collection of clearance soil samples specified in this Section V.J.1.e.(ii)(A) of this Regulation Number 19, Part A is not required. The visual inspection requirement specified in Section V.J.1.a. (Visual Inspection) of this Regulation Number 19, Part A, still applies to soil-only abatement projects.
V.J.1.f. The rooms, hallways or stairwells or exterior areas selected for sampling must be selected according to documented methodologies.
V.J.1.g. The certified inspector or risk assessor must compare the residual lead level (as determined by the laboratory analysis) from each dust and soil sample with applicable clearance levels for lead in dust and soil on floors, windows, and other surfaces.
V.J.1.g.(i) If the residual lead level in a single surface dust sample equals or exceeds 10 µg/ ft2 on interior floors, 100 µg/ ft2 on interior window sills, 400 µg/ ft2 on window troughs, 500 µg/ ft2 on exterior window sills, or 800 µg/ ft2 on exterior surfaces (e.g. patios, porches, sidewalks), or if the residual lead level in a composite dust sample equals or exceeds the applicable clearance level divided by half the number of subsamples in the composite sample, all the components represented by the failed sample must be re-cleaned and re-tested until clearance levels are met.
V.J.1.g.(ii) If the residual lead levels in a soil sample exceed 400 µg/g in a play area, or 1,200 µg/g in the rest of the yard, the soil must be abated in accordance with Section V.F. (Soil Abatement) of this Regulation Number 19, Part A.
V.J.2. In a pre-1978 multi-family dwelling with similarly constructed and maintained pre-1978 residential dwellings, random sampling for the purposes of clearance may be conducted provided:
V.J.2.a. the certified individuals who abate or clean the pre-1978 residential dwellings do not know which residential dwellings will be selected for the random samples;
V.J.2.b. in accordance with Appendix A, a sufficient number of pre-1978 residential dwellings are selected for dust and soil sampling to provide a 95 percent level of confidence that no more than 5 percent or 50 of the residential dwellings (whichever is smaller) in the randomly sampled population exceed the appropriate clearance levels specified in Section V.J.1.g. of this Regulation Number 19, Part A; and
V.J.2.c. the randomly selected pre-1978 residential dwellings are sampled and evaluated for clearance according to the procedures found in Section V.J.1. of this Regulation Number 19, Part A.
V.J.3. An abatement report must be prepared by a certified supervisor or project designer. The abatement report must be completed within ninety days following the successful clearance of the project and include the following information:
V.J.3.a. start and completion dates of abatement;
V.J.3.b. the name and address of each certified LAF conducting the abatement and the name of each supervisor assigned to the abatement project;
V.J.3.c. the occupant protection plan prepared pursuant to Section V.A.6. (Occupant Protection Plan) of this Regulation Number 19, Part A;
V.J.3.d. the name and address of each certified LEF and the name, address and signature of each certified risk assessor or inspector conducting clearance sampling and the date of clearance testing;
V.J.3.e. the results of clearance testing and all soil analyses (if applicable) and the name of each recognized laboratory that conducted the analyses; and
V.J.3.f. a detailed written description of the abatement, including abatement methods used, locations of rooms and/or components where abatement occurred, reason for selecting particular abatement methods for each component, any suggested monitoring of encapsulants or enclosure, and any suggested post-abatement maintenance and cleaning methods.
V.J.4. Collection and laboratory analysis of samples. Any dust or soil samples collected pursuant to this Section V.J. (Final Clearance) of this Regulation Number 19, Part A must be:
V.J.4.a. collected by persons certified by the Division as an inspector or risk assessor working for a LEF; and
V.J.4.b. analyzed by a recognized laboratory.
V.J.5. Composite dust sampling. Composite dust sampling may only be conducted in the situations specified in this Section V.J. (Final Clearance) of this Regulation Number 19, Part A. If such sampling is conducted, the following conditions must apply:
V.J.5.a. composite dust samples must consist of at least two subsamples, but no more than four subsamples;
V.J.5.b. every component that is being tested must be included in the sampling; and
V.J.5.c. composite dust samples must not consist of subsamples from more than one type of component.
V.K. Waste Handling

Each person handling any lead-contaminated waste must comply with the following requirements:

V.K.1. wrap and seal lead-contaminated waste in at least 6-mil thick polyethylene sheeting prior to removing the waste from the containment or abatement work area;
V.K.2. store the waste in a covered container within a designated secure (locked) area, if not transported immediately off-site;
V.K.3. do not cut or break painted materials or perform any action that is likely to generate leaded dust;
V.K.4. comply with all local, State and Federal waste handling and disposal requirements; and
V.K.5. discharge no visible emissions during any handling of lead-contaminated waste outside the work area.
V.L. Recordkeeping

All reports or plans required in this Section V. (Abatement Requirements) of this Regulation Number 19, Part A, must be retained for no fewer than 3 years by the certified firm or individual who prepared the report. The certified firm or individual also must provide copies of these reports to the building owner who contracted for its services. Additionally, these records, if requested, must be made available to the Division to demonstrate compliance with this Section V.L.

V.M. Alternative Procedures and Variances

The Division may, at its discretion, grant a variance from the requirements in this Section V. (Abatement Requirements) of this Regulation Number 19, Part A, allowing use of an alternative procedure for the clearance of abatement projects or the control of emissions from a lead abatement project provided that the person conducting the abatement submit an alternative procedure in writing to the Division and demonstrates to the satisfaction of the Division that compliance with this Regulation Number 19, Part A is not practical or that the proposed alternative procedures provide equivalent control of lead.

Within forty-five (45) days of the receipt of the request the Division will notify the applicant in writing of its decision to either grant or deny the variance. If the variance is denied, the Division will provide a reason for the denial to the applicant. No person may begin abatement using such a procedure until a variance has been requested and approved in writing. Any violation of any condition of the variance will be considered a violation of this Regulation.
