Qualifications for Clearance examiners. The owner, funding agency, certified abatement contractor, or certified renovation contractor should select the Clearance examiner, preferably before lead-based paint hazard control work begins.

8 Clearance on all projects involving abatement (as defined by EPA) must be done by a certified risk assessor or a certified lead-based paint inspector. Check with EPA regarding qualifications for clear-ance of non-abatement activities. For properties covered by HUD s Lead Safe Housing Rule, and those of some State regulations, clear-ance of non-abatement work may be performed by a certified risk assessor or lead-based paint inspec-tor, or by a certified sampling technician, if the sampling technician is working in single family units or a multi-family dwelling unit and the associated common areas.

9 If the Clearance requires development of a random sampling plan, a certified inspector or risk assessor must develop the plan and supervise the sampling technician in its use. Not all States or localities have certified sampling technicians, and some require that non-abatement Clearance be conducted only by certified risk assessors or inspectors. For clearing projects covered by the EPA s Renovation, Repair, and Painting (RRP) rule, a certified risk assessor, certified lead-based paint inspector, or certified dust sampling technician can perform clear-ance. (See below regarding clearing multi-family housing projects.)

10 To eliminate conflicts of interest, these Guidelines recommend the use of a Clearance examiner who is completely independent of the contractor who performs the work. HUD s Lead Safe Housing Rule requires such independence for Clearance of most work in HUD-assisted target housing. (See Appendix 6 for details.)2. Determine the Clearance area. Obtain information from the client regarding the nature and location of the work and the dust containment (if any); for an abatement, project, validate or obtain a copy of the abatement site plan. Then determine the Clearance area ( , the dwelling units, common areas, rooms, and/or exterior areas that are subject to the Clearance examination).
