Appendix C) which shall be included as an attachment to the Clearance Sampling Plan and submitted as
part of the Lead Hazard Clearance Report following completion of the clearance inspection. If during
the visual examination, the Contractor determines that the required lead hazard control work treatments
have not been completed, or if visible dust or debris remains on the floor and other surfaces, the
Contractor shall notify the Contracting Officer who will ensure that the Lead Hazard Control Contractor
completes the project properly and re-cleans the units as required in the original project scope. The
Contracting Officer reserves the right to audit the accuracy of Contractor's visual examination findings
as recorded on Form 1 for any unit, at any time during the course of the project.
2.2.2
Sampling
******************************************************************************
NOTE: Soil sampling is required when exterior lead hazard control work OTHER than
soil covering has been performed.
******************************************************************************
Clearance sampling shall include the collection and analysis of single-surface dust wipe [and soil]
samples in order to determine whether lead concentrations in [this matrix] [these matrices] exceed
clearance action levels specified in Table A-1. Dust wipe samples used to make this determination shall
be collected from surfaces no sooner than one hour after lead hazard control clean-up has been
performed to the satisfaction of the Contractor based on the visual examination. Sampling soil in order
to evaluate the effectiveness of soil treatments (such as soil replacement) other than soil covering, which
does not require sampling, shall be completed through composite sampling only. Soil covering shall
require only a visual inspection.
2.2.2.1
Dust Wipe Sampling
******************************************************************************
NOTE: The following sampling categories are based on 40 CFR 745.227 requirements
and HUD guidelines for "Target Housing" (defined by the EPA 40 CFR 745.223).
******************************************************************************
Clearance dust wipe samples shall be collected from locations at, adjacent to or close to the completed
lead hazard control treatments, including nearby high-traffic areas (e.g., near doorways) where
applicable. The number and location of the clearance samples shall be based on the type of
containment used and the number of rooms treated, rather than the use patterns of a particular room.
The building components that must be tested include floors, interior windowsills, window troughs, [ ].
The Contractor shall determine the specific sampling location, based on the type of treatment, visual
observation, and professional judgement. The Lead Hazard Control Contractor shall not be informed
as to where the clearance samples will be collected by the Contractor. At a minimum, the following
guidelines for single-surface wipe samples, shall be followed for target housing unit clearance:
