Should substrate correction not be required by the XRF manufacturer, the contractor shall comply with all instructions for use and calibration. 2.2.1.3Surface Testing Using XRF Measurement The lead inspector/risk assessor shall test at least three locations per testing combination, except for interior and exterior four-wall combinations comprising the typical room or building exterior, where four readings shall be taken, one on each wall. The selection of the test location for a specific testing combination shall be representative of the paint over the areas. All layers of paint shall be included and the XRF probe faceplate shall be able to lie flat against the surface at the test location. If no acceptable location for XRF testing exists for a given testing combination, paint-chip samples shall be collected and submitted to the laboratory per ASTM's Standard Practice for Field Collection of Dried Paint Samples for Lead Determination by Atomic Spectrometry Techniques (E 1729). All testing locations shall be marked on the floor plans/sketches and provided using HUD Guideline Forms 5.0-5.7 (HUD-1539-LBP) or equivalent. 2.2.1.4Classification of XRF Results The lead inspector/risk assessor shall classify the XRF results as positive, negative or inconclusive as defined in the XRF instrument's PC sheet. Test results are positive if they are greater than the upper boundary of the inconclusive range, negative if they are less than the lower boundary of the inconclusive range, or inconclusive if in between. The inconclusive range includes both its upper and lower bounds. All XRF data shall be recorded for each testing combination and submitted as an attachment to the Lead Inspection/Risk Assessment Report. Field-repeated testing shall be accomplished, at no additional cost to the VHA, in accordance with the XRF validation requirements of this SOW. Paint chip samples shall be collected for all inconclusive XRF readings in addition to those surfaces where the XRF cannot be properly operated (e.g., small, rounded, surfaces etc.). The location of all paint chip samples shall be documented on the building drawing and documented in accordance with this SOW. 2.2.2Risk Assessment 2.2.2.1Visual Assessment The lead inspector/risk assessor shall perform concurrently with the lead inspection visual assessment, an assessment of all rooms and surfaces to locate potential LBP hazards and to evaluate the magnitude of each hazard. Following the floor plans or sketches, the lead inspector/risk assessor shall visually inspect the exterior and every room that will be assessed to evaluate paint and other building components with a coating that might contain lead such as ceramic tile glaze and building conditions. Every lead containing building material and lead- based paint or coating component system with the same distinct painting or coating history (see Glossary) testing positive for lead shall be inspected for deterioration. The lead inspector/risk assessor shall review the XRF data recorded and identify through observation: "Any friction surface or impact surface with visibly deteriorated paint or coating, and "All other lead-based paint or coating surfaces with visible deteriorated paint. "Visible paint and coating debris and particulate "Damaged or deteriorated lead containing building materials The lead inspector/risk assessor shall visually assess surfaces in common areas. The lead inspector/risk assessor shall inspect deterioration on friction and impact surfaces by operating and examining the friction and/or impact surfaces of several of the windows and doors that are used most frequently (as determined by accessibility) that contain LBP. The visual assessment shall be documented using HUD Guidelines Forms 5.0-5.7 (HUD-1539-LBP) or equivalent. The forms shall be submitted as attachments to the Lead Inspection/Risk Assessment Report. 2.2.2.2Sample Location Selection The lead inspector/risk assessor shall select single surface dust wipe sample locations during the visual assessment. Paint chip samples, as required, should be selected in concert with the lead inspection phase of the project. Chip samples of other coatings will be obtained where possible and damage is not readily observable. Sample locations for each unit shall be identified on each unit floor plan or sketch, and shall be based on visual observations, separate component systems with distinct histories, pre- assessment unit information (including physical characteristics, use patterns, previous study results), and on the following: "Samples shall not be collected from worn portions of the painted surfaces. "Friction or impact surface hazards shall be evaluated by dust wipe analysis, and accordingly shall not require paint chip or coating sampling. a.Dust Wipe Sample Locations One dust sample shall be collected from interior window sills and floors in all areas representing distinct component systems. Any lead-based paint on a friction surface with visibly deteriorated paint or that is subject to abrasion shall be sampled where the lead dust levels on the nearest horizontal surface beneath the friction surface can potentially exceed the dust-lead hazard action levels in Table A-1. b.Paint and Coating Chip Sample Locations The lead inspector/risk assessor shall immediately review the results of the lead inspection, and determine if any identified lead bearing surfaces contain deteriorated paint or coating and note the extent of the damage. c.Bulk/Building Material Sample Locations The lead inspector/risk assessor shall collect a bulk/building material sample whereever XRF sampling cannot definitively delineate the lead containing material (ie. Paint, glazing, radiation shielding) 2.2.2.3Risk Assessment Sample and Sample Location Documentation All XRF testing locations shall be marked on the floor plans/sketches and forms at the time of actual testing during the inspection phase of the combined inspection/risk assessment. Bulk/building material, paint and coating chip, and surface wipe sample locations shall also be recorded on the floor plans/ sketches. The Contracting Officer and his technical representative reserves the right to audit the Risk Assessment Sample and Sample Location Documentation at any time during the course of the project. The Risk Assessment Sample and Sample Location Documentation shall be included as an attachment to the Risk Assessment Sampling Plan following completion of the fieldwork and submitted as a part of the Lead Inspection/Risk Assessment Report. 2.2.3Single Surface Dust Sampling Dust samples shall be collected for analysis by single surface wipe sampling. Dust wipe samples shall always be collected before paint and coating chip samples to avoid cross- contamination. The lead inspector/risk assessor shall collect wipe samples in accordance with ASTM's Standard Practice for Field Collection of Settled Dust Samples Using Wipe Sampling Methods for Lead Determination by Atomic Spectrometry Techniques (E 1728), using wipe materials meeting the requirements of Standard Specification for Wipe Sampling Materials for Lead in Surface Dust (E 1792). 2.2.4Deteriorated Paint and Coating Chip Sampling The XRF data of this assessment shall be used to evaluate all deteriorated paint surfaces for the presence of lead. Deteriorated painted surfaces that were not suitable for testing by XRF due to shape, or accessibility etc., or where inconclusive XRF readings were generated during the inspection phase, shall be tested destructively by chip sample collection. The chip samples shall be collected and submitted in accordance with the laboratory's SOP for collecting paint chip samples to determine lead loading per cc of surface area, and ASTM's Standard Practice for Field Collection of Dried Paint Samples for Lead Determination by Atomic Spectrometry Techniques (E 1729). 2.2.5Sample Identification Dust, paint and coating, and Bulk/Building Material samples shall be identified using unique sample numbers. Field and laboratory blanks and spiked samples submitted to the laboratory for QA/QC purposes shall be numbered in such a way that the sample identity will not be revealed to personnel conducting the analysis. 2.2.6Sample Chain-of-Custody The Contractor shall follow a standard chain-of-custody protocol to ensure and document a continuous record of sample possession from sample collection to receipt by the laboratory. The Contractor shall complete and maintain chain-of-custody forms for each set of samples shipped to the laboratory, and a copy of the forms shall accompany each shipment of samples. The Contractor shall include copies of all chain-of-custody forms completed during the assessment in the Lead Inspection/Risk Assessment Report. 2.2.7Decontamination Field sampling equipment shall be decontaminated following the appropriate ASTM standard. At a minimum, the field decontamination procedures for non-disposable sampling equipment (e.g., knives, coring devices, scrapers) shall consist of either wiping the equipment off twice using a clean wet wipe each time, or washing in a solution of non-phosphate detergent (e.g., Liquinox �), and rinsing with distilled water. The equipment shall be decontaminated prior to each use, between each sample, and prior to leaving the site. The Contractor shall coordinate with the installation environmental officer to determine requirements for the disposal of decontamination waste and used personal protective equipment. 2.3TASK 3 SAMPLE DATA ANALYSIS, EVALUATION OF FINDINGS 2.3.1XRF Data Interpretation XRF results shall be interpreted by the Contractor in accordance with ASTM Standards, the XRF manufacturer's PCS, and as otherwise required in this SOW. 2.3.2Sample Preparation and Analysis Samples collected by the lead inspector/risk assessor during the assessment(s) shall be sent to a laboratory recognized by the EPA under the (National Lead Laboratory Accreditation Porgram (NLLAP) for analysis. The laboratory must be accredited for each type of analysis required. The Contractor shall submit copies of the laboratories NLLAP certification. 2.3.2.1Laboratory Turnaround Time The Contractor shall require the laboratory to report analytical results to the Contractor within 5 days of the laboratory's receipt of the samples in the laboratory. 2.3.3Quality Assurance and Quality Control (QA/QC) 2.3.3.1XRF Performance Validation and Verification The lead inspector/risk assessor shall use only XRF spectrum analyzers with current, published Performance Characteristic (PCS) sheets that provide valid measurements at the levels specified in Table A-1. A copy of the PCS for the XRF instruments used on this project shall be submitted in the Lead Inspection Sampling Plan section of the Lead Inspection/Risk Assessment Report. The lead inspector/risk assessor shall perform calibration checks at the beginning and end of the inspection work or every four hours, whichever comes first or as otherwise specified in Chapter 7 of the HUD Guidelines: "Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, June 1995. (Chapter 7 revised 1997)". If the PCS of the XRF spectrum analyzer manufacturer requires additional or more stringent warm up, quality control, or calibration check instructions than those described in the HUD Guidelines, they shall be followed. Calibration shall also be performed before and after turning the instrument on or off throughout the inspection work (e.g., lunch breaks, changing batteries). If the failed calibration results occur at the end of a testing period, the results obtained during that testing period shall be discarded and the unit re-tested. The lead inspector/risk assessor shall record all calibration check results and submit this record in the Contractor Data Certification section of the Lead Inspection/Risk Assessment Report. Validation shall be accomplished with the lead inspector/risk assessor randomly selecting 10 testing combinations for retesting in the surveyed units for every 10 units tested or 5 tests per day, for single facility surveys. The retesting shall be with the same XRF spectrum analyzer. The average of the 5-10 XRF retest results shall not vary from the 5-10 original XRF results by more than the retest tolerance limit that is calculated as specified on the XRF PCS sheet. If the limit is exceeded, the procedure shall be repeated using 5-10 different testing combinations. If the retest tolerance is exceeded again, the original inspection is considered invalid.This process must be documented and submitted in the Contractor Data Certification section of the Lead Inspection/Risk Assessment Report. 2.3.3.2Field Blank Dust Wipe QA Samples Field blanks for single wipe sampling shall be collected in accordance with ASTM's "Standard Practice for Field Collection of Settled Dust Samples Using Wipe Sampling Methods for Lead Determination by Atomic Spectrometry Techniques", (E 1728). Wipe materials shall meet the requirements of "Standard Specification for Wipe Sampling Materials for Lead in Surface Dust", (E 1792) using the same wipe material used to collect the field wipe samples. There shall be no indication to the laboratory, by sample identification numbers or other means, that the field blank samples are QA samples. 2.3.3.3Field Spike Dust Wipe QA Samples The Contractor shall submit double-blind (spiked) QA dust wipe samples to the laboratory at a frequency of 2% of total samples collected, with a minimum of one sample using one of the two following options: a.The Contractor shall obtain commercially prepared spiked wipe samples meeting the same QA/QC requirements required in preparing spiked wipe samples used by the AIHA in its management of the Environmental Lead Proficiency Analytical Testing (ELPAT) laboratory certification program, for submittal to the laboratory. The contractor shall obtain and use wipes of the same brand and type as those used to prepare the spiked samples. The Contractor shall use these wipes to collect field samples and to prepare field blank samples. b. The Contractor shall hire a laboratory to prepare spiked wipe samples using National Institute of Standards and Testing (NIST) traceable materials. Spiked samples shall be prepared using leaded dust, not lead in solution. The lead concentration in the spiked wipe samples shall approximate the amount of lead in the lead action level criteria for hard floors in Table A-1 of this SOW. The Contractor shall provide uncontaminated wipes of the same brand and lot as the wipes that will be used to collect field samples, to the laboratory preparing the spiked samples. The laboratory shall use these wipes to prepare the spiked wipe samples. The laboratory preparing the spiked samples shall be independent of the laboratory that will be used to analyze the field samples and field QA samples. There shall be no indication to the laboratory analyzing the field samples, by sample identification numbers or other means, that the spiked samples are QA samples. 2.3.3.4Field Duplicate/Spike Paint Chip QA Samples The Contractor shall submit double-blind QA paint and coating chip samples to the laboratory for analysis. At a minimum, these shall include field duplicate samples, prepared by using standard mortar and pestle homogenizing techniques, collected at a rate of 2% of total samples collected, with a minimum of one sample. The Contractor may also submit standard reference samples (commercially-prepared paint chip samples with a known concentration of lead) at a rate of 2% of the total samples collected, to the laboratory for analysis. The lead concentration in the samples used shall be within 75% to 125% of the lead hazard action levels in Table A-1 if available. There shall be no indication to the laboratory, by sample identification numbers or other means, that the samples are QA samples. The Contractor shall evaluate the results of the analyses of QA samples and include this evaluation in the final report. 2.3.4Project Data Review and Assessment The Contractor shall review all project data collected as part of the current assessment and verify that the data is acceptable. Data review includes (1) Field sample collection and control review, and (2) analytical laboratory data review. Field sample collection and control review includes evaluating the adequacy of the Lead Inspection Sampling Plan and Risk Assessment Sampling Plan throughout the performance of the assessment. 2.3.4.1Field Dust Wipe Quality Assurance Verification Prior to beginning field dust sampling, the Contractor shall provide the laboratory with at least one uncontaminated wipe per each container of bulk packed wipes that will be used for collecting field dust wipes, to verify that the wipe material meets the requirements of Standard Specification for Wipe Sampling Materials for Lead in Surface Dust (E 1792). Wipes containing more than 5.0 g/wipe of background lead shall render the entire container of bulk packed wipes represented by the analyzed wipe, contaminated and disqualify the represented wipes for field use.Pre-analysis data by the vendor is acceptable as meeting this requirement. (See AIHA web site for a listing of wipe vendors meeting ASTM Method E 1792 criteria.) 2.3.4.2Laboratory QA and QC Verification. a.Evaluation of Laboratory Data The Contractor shall obtain and review NLLAP-required QC data generated for each sample run completed under this SOW. The QC data shall include batch QC validation data and the 95% confidence interval data (determined by the laboratory from QC charts or a QC database for each matrix, i.e., single surface dust wipe samples, deteriorated paint chip samples, soil samples) determined at concentrations equivalent to 40 g/ft2 for dust wipe samples, 0.5% by weight (5000 g/g (ppm)) for paint chip samples, and 400 g/g (ppm)) for bulk soil samples. The Contractor shall evaluate the data package to determine that the QA/QC data generated for each sample run falls within current NLLAP Laboratory Quality System Requirements (LQSR) parameters. Spiked samples submitted to the laboratory in accordance with this SOW shall fall within 75% - 125% of the true value. b.Rejection of Laboratory Data The Contractor shall not accept or use data from the laboratory that does not fall within current NLLAP LQSR parameters. If the laboratory fails to obtain spiked results within the specified error limits: "Two more spikes of the same matrix shall be sent immediately to the laboratory for analysis. "If the two additional spike samples fail, the sample batch shall be considered invalid for the matrix represented. If laboratory data are rejected and insufficient quantities of the samples remain to allow re-analysis of the samples while adhering to QA/QC requirements, the Contractor shall collect and submit additional samples, at no cost to the Government, for laboratory analysis using NLLAP QA/QC protocols. The Contractor shall also be responsible for any re-sampling required due to laboratory errors that result in the destruction or loss of data, or a failure to report results on any samples submitted. 2.3.4.3Contractor Certification of Project Data Validity The Contractor shall certify that all field data collected to determine the presence of a lead hazard were valid. 2.3.4.4Comparison with Lead Hazard Action Levels The Contractor shall compare the collected data and Table A-1 criteria to determine whether lead-based paint and/or lead hazards are present. This comparison shall be documented in the Lead Inspection/Risk Assessment Report and meet the HUD guidelines for Lead-Based Paint in Target Housing. For all lead hazard evaluations, the data shall be examined to determine if consistent patterns emerge (e.g., the window troughs contain high levels, while floors and interior sills are low); such patterns will be used in the development of recommendations for focused cost-effective control measures. 2.3.4.5Laboratory Report The Contractor shall require that the laboratory report information necessary for the Contractor to comply with the data evaluation/validation requirements outlined in this SOW. The Laboratory Report shall include the following information addressing all field samples submitted to it by the Contractor excluding sample data collected by the Contractor using XRF instrumentation: "Cover page information including Laboratory name and address, methods, dates, instruments, digestions, and laboratory director.

The contractor must possess all valid licenses and certifications as required by state regulations and the CO. The term "contractor" in this SOW also implies the firm that is or hires the lead inspectors/risk assessors. When this term is used in this SOW, it implies both. Data Quality Objective Deteriorated paintThe qualitative and quantitative statements, guidelines, and requirements presented in paragraphs 2.2 and 2.3 of this SOW that clarify study objectives, define the appropriate type of data, and specify the tolerance levels of potential errors that will be used as the basis for establishing the quality of the data needed to support decisions. Paint that is cracking, flaking, chipping, peeling, or otherwise separating from the substrate of a building component. (40 CFR 745.223) Distinct painting historyThe 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. (40 CFR 745.223) Double-blind sampleFor the purposes of this SOW, this refers to a QC sample (replicate, duplicate, spiked sample, etc.) that is sent to the laboratory with no indication of the possible lead content and without identifying the sample as a QC sample. Lead-based paint (LBP)Paint or other surface coatings that contain lead equal to or in excess of 1.0 milligrams per square centimeter or more than 0.5 percent by weight (5000 g/g or parts per million). (40 CFR 745.223). Throughout this document, "lead-based paint", "paint", and "coating" are used to cumulatively refer to substances applied to the surfaces of building materials for decorative or functional requirements or purposes. Lead-based paint hazard Any condition that causes exposure to lead from dust- lead hazards, soil-lead hazards, or lead-based paint that is deteriorated or present in chewable surfaces, friction surfaces, or impact surfaces, and that would result in adverse human health effects. (40 CFR Part 745) Lead-based paint inspectionA surface-by-surface investigation to determine the presence of lead-based paint and coating and the provision of a report explaining the results of the investigation.

QAQuality assurance; defined by NLLAP as an "integrated system of activities involving planning, QC, quality assessment, reporting, and quality improvement to ensure that a product or service meets defined standards of quality within a state level of confidence." (NLLAP LQSR ) QCQuality control; defined by NLLAP as the "overall system of technical activities whose purpose is to measure and control the quality of a product or service so that it meets the needs of users. The aim is to provide quality that is satisfactory, adequate, dependable, and economical. (NLLAP LQSR) Random SamplingA technique for selecting a sample of n elements from a population of elements in such a way that each combination of n elements has the same probability of being selected. In statistical sampling, the process of selecting sample units in such a way that all units under consideration have the same probability of being selected. (ASTM E1605) Rinsate BlankA sample of "used" cleaning fluid rinse solution, also called equipment blank. The rinsate blank is used in rinsing collection equipment to monitor possible cross contamination.(EPA, 757-R-92-006, May 1993) Risk assessmentAn on-site investigation and report to determine the existence, nature, severity, and location of lead-based paint hazards.

(40 CFR 745.223) Room equivalentA room equivalent is an identifiable part of a residence, such as a room, a house exterior, a foyer, staircase, hallway, or an exterior area (exterior areas contain items such as play areas, painted swing sets, painted sandboxes, etc.). For multifamily units or apartment buildings, common areas and exterior sites are treated as separate types of units, not as room equivalents (HUD Guidelines, Chapter 7, current Revision). SubstrateThe substrate is the material underneath the paint or coating. Substrates should be classified into one of six types: brick, concrete, drywall, metal, plaster, or wood. These substrates cover almost all-building materials that are painted and are linked to those used in the XRF performance characteristic sheets.( HUD Guidelines, Chapter 7, current Revision) Suspect Building MaterialBuilding materials which brands or manufacturers are known contain lead or which have coatings or glazings that have been known to contain lead or lead paints. Testing CombinationA unique combination of room equivalent, building component type, and substrate. (HUD guidelines, Chapter 7, current revision) X-Ray Fluorescence Analyzer (XRF) XRF Performance Characteristic Sheet (PC)An instrument that determines lead concentration in milligrams per square centimeter (mg/cm2) using the principle of x-ray fluorescence (XRF). (HUD Guidelines) The "P.C. Sheet" is unique for each XRF Instrument. It specifies the inconclusive range, calibration check tolerance, and other instrument - specific information.
