NOTE TO SCOPE OF WORK EDITOR:

This standard scope of work (SOW) defines lead hazard clearance following lead 

hazard control activities (see Glossary) at Department of Army (DA) target housing or 

child-occupied facilities (see Glossary). The Scope-of-Work Editor must have 

completed the training required for risk assessors defined in EPA 40 Code of Federal 

Regulations (CFR) 745 Subpart L “Lead-Based Paint Activities” prior to editing this 

SOW for the lead hazard clearance projects. 

This SOW does not define lead hazard clearance for non-target housing projects. 

Clearance requirements for non-target housing/child occupied facilities are to be found 

in the design specifications for those projects. Risk assessor training is recommended, 

but not required for developing project specific clearance criteria to be used for nontarget housing specifications. 

 This SOW incorporates 40 CFR 745 Subpart L requirements for clearance using the 

sampling protocol found both in 40 CFR 745.227 and developed by the Department of 

Housing and Urban Development (HUD) for target housing. 

The SOW does not include unique clearance procedures for facilities involved in child 

elevated blood lead level (EBL) issues. Elevated blood lead evaluations address lead 

sources to children such as contaminated eating utensils, food and beverage containers, 

personal hygiene practices, offsite daycare, community water supply, public 

playgrounds, etc. EBL evaluations require coordinated professional resources involving 

a number of agencies, including state and local public health departments.

1.2 REGULATORY REQUIREMENTS

1.2.1 Regulatory Authority/Requirements

The Contractor shall conduct all work in accordance with Federal, State and local requirements. 

Where inconsistencies exist between the requirements and this SOW, the Contractor shall specify the 

procedures providing the most accurate data and requiring the most rigorous clearance. 

1.2.1.1 Federal Requirements

a. Clearance Requirements and Procedures 

******************************************************************************
EP 1110-1-29

31 Aug 01

A-9

NOTE: The cited 40 CFR regulations and June 1995 HUD Guidelines specify clearance procedures for 

target housing/child occupied facilities and are the procedures included in this SOW. The procedures 

are to be used for both active target housing and target housing slated for BRAC property transfer. 

Paint, Dust, and Soil-Lead Hazard definitions in 40 CFR Part 745 Subpart D Section 65 are used in 

defining the cleanup clearance action levels for active housing and residential BRAC property transfers 

in this SOW. 

******************************************************************************

The Contractor shall evaluate clearance against action levels specified in Table A-1 by meeting the Data 

Quality Objectives (See Glossary) (DQO) to comply with 40 CFR 745.227(e)(8), (e)(9), and (h) [and 

with 24 CFR 35.1340] using methodologies specified and where not specified, using those found in 

Chapter 15, “Guidelines for the Evaluation and Control of Lead- Based Paint Hazards in Housing”, 

Department of Housing and Urban Development (HUD Guidelines, June 1995, as revised) as 

summarized in this SOW.

b. Safety and Health

The Contractor shall comply with applicable OSHA standards and with the USACE Safety and Health 

Requirements Manual EM 385-1-1 including submitting an Accident Prevention Plan (APP) to the 

Contracting Officer (see Glossary) prior to performing field activities. Field activities shall not begin 

without acceptance of the APP by the Contracting Officer.

1.2.1.2 State and Local Requirements

******************************************************************************

NOTE: Reference state, local, or installation specific requirements that differ from the 

Federal requirements cited in this SOW that are applicable to the clearance to be 

performed.

******************************************************************************

[The Contractor shall comply with the following state and local/installation requirements in completing 

the activities required by this SOW. [insert applicable requirements ]]

1.3 SITE CHARACTERISTICS, OBJECTIVES AND DESCRIPTION OF WORK

1.3.1 Site Location/Project Characteristics

******************************************************************************

NOTE: Identify all units and surfaces within each unit that will be included in the 

clearance inspection. Provide a description of the work tasks and the extent of work 

that was performed by the lead hazard control contractor, including a list of surfaces 

that did not receive treatment; by providing access to the original SOW, specifications, 

and/or contractor completion report.

******************************************************************************
EP 1110-1-29

31 Aug 01

A-10

The units requiring clearance evaluation are located at: 

[Insert the unit or facility address(es) and unique unit or room identifiers]

The Contractor shall review descriptions of all work tasks completed by the lead hazard control 

contractor and descriptions of all associated lead hazard control treatments described below and in 

Contract # [insert lead hazard control project #, page and paragraph as appropriate] (see attached) 

before beginning Task # 2: 

[list work tasks and lead hazard control treatments from the original project that require 

clearance under this SOW]

1.3.2 Clearance Objectives and Description of Work

The Contractor shall determine through the clearance inspection process defined in this SOW whether:

• The lead hazard control treatments described in this SOW were successfully performed 

by visual examination and dust and soil sampling if required.

• The lead hazard control project treatments meet the clearance action level criteria in 

Table A-1, thereby assuring the Contracting Officer of the absence of lead-based paint 

deterioration and that lead dust or soil lead levels remaining are considered nonhazardous by 40 CFR 745 Subpart L requirements. 

• The lead hazard control project activities and clean-up meet Federal and DA standards 

and guidelines as specified in this SOW. 

1.3.3 Data Quality Objectives

******************************************************************************

NOTE: The clearance action levels that are found in the project SOW, specifications, 

or contractor’s completion report and Table A-1 below should be in agreement. Some 

states/municipalities use lead loading values (mg/cc of surface area) associated with the 

use of XRF readings that differ from and are more stringent than the federal values listed 

here in Table A-1. Check with local authorities for applicable criteria at project site and 

modify Table A-1 accordingly. The action levels provided in Table A-1 are for target 

housing/child occupied facilities, at “active” Army installations and also BRAC property 

transfers. Clearance for BRAC properties may not be required since liability for 

identified lead hazards found during the lead inspection/risk assessment process may be 

transferred to the buyer under the purchase contract. Check with the customer.

******************************************************************************

The Contractor’s work shall meet project-specific DQOs for sampling, analysis, and Quality

Assurance/Quality Control (QA/QC). DQOs shall be met in order to provide project required data

quality. The data thus collected shall be compared to clearance action levels provided in Table A-1 
EP 1110-1-29

below. Clearance will be considered acceptable when the results of all validated samples collected by 

the Contractor fall below the clearance action levels. The Contracting Officer shall be notified 

immediately if clearance sample results provided by the Contractor exceed the clearance action levels in 

Table A-1.

1.3.4 Bid Assumptions

******************************************************************************

NOTE: Include project-specific assumptions for the Contractor to use in developing a 

cost estimate. Provide site-specific information to assist in developing realistic

assumptions. Review Task # 1, Task # 2 and Task # 3 requirements prior to 

developing this paragraph. Use the recommended number of dust wipes based on the 

treatment category that applies to the project to calculate the average number of wipes 

per unit for bidding purposes, i.e., Category #1: 2 dust wipes per room for each room 

up to 4 rooms for each unit plus one sample for each 2000 square feet of common area, 

etc. In addition to the field wipes, field blanks must be included based on the total 

number of field wipes submitted in the batch in accordance with ASTM E 1728. 

Sample analysis cost can range to $25.00. Check with NLLAP qualified laboratories in 

the area. At least one dust spike sample must be submitted to the laboratory for the 

first 50 field dust wipes, and at a rate of one per 50 field wipes thereafter.

locations as a part of developing clearance sample location documentation while performing the 

clearance inspection.

2.1.3 Preliminary Site Visit/Walkover

The Contractor shall conduct a preliminary site visit/walkover. This walkover shall be used to ensure 

that all site-specific conditions and special accessibility requirements are addressed in the Project Work 

Plan.

2.1.4 Project Work Plan

******************************************************************************

NOTE: The clearance risk assessor in all cases must be completely free to determine 

the exact location of each sample, all without providing this knowledge “up front” to the 

remediation contractor.

******************************************************************************

The Contractor shall submit a Project Work Plan to the Contracting Officer for government approval 

prior to initiating Task # 2. The plan shall include:

• Accident Prevention Plan

• Project clearance objectives and requirements including any special access scheduling 

requirements, escort requirements, laboratory turn-around requirements if different than 

as specified in this SOW.

• Clearance Sampling Plan to include a description of the sampling location decision logic, 

the type of samples and how the samples are to be collected and handled and analyzed

2.2 TASK 2 CLEARANCE SAMPLING

2.2.1 Visual Assessment

The Contractor shall visually examine the lead hazard control project areas identified in Paragraph 

1.3.1. The Contractor shall visually determine and document whether the lead hazard control 

treatments (see Glossary) have been performed or completed on all treated interior and exterior 

surfaces, and whether visible dust or debris are present.

A visual examination of completed work shall be completed as outlined and summarized below:
EP 1110-1-29

31 Aug 01

A-15

• The visual examination shall be started no sooner than one hour after completion of 

cleanup activities in the unit/facility that will be evaluated, to allow sufficient time for 

potential lead-contaminated dust to settle,

• The visual examination shall be performed with an understanding of the extent of the 

lead hazard control work and also all surfaces that did not receive treatment. 

• The visual examination shall include a room-by-room, component-by-component 

examination [including exterior and common areas] to determine whether the lead 

hazard control treatments have been completed as required, and to determine if waste 

and visible dust or debris is still present. The results of the visual examination shall be

documented on Form 1 (Figure C-1, Appendix C). [Bare surfaces created by paint 

removal shall be examined prior to repainting to confirm the absence of visible residue. 

Wipe sampling shall not be used to document paint removal from a given surface.] 

[Building component replacement shall be visually examined and documented for each 

individual component replaced.] [The dust tightness of mechanical fastening systems 

(seam and edge seals) shall be visually examined and documented for all enclosures.] 

[The completion of soil treatments such as coverings, or removal/replacement shall be 

visually examined and documented.] [The presence of encapsulants shall be visually 

examined and documented.] [Interim controls shall be visually examined and 

documented to confirm stabilization of all Lead-Based Paint (LBP) surfaces.] The 

Contracting Officer shall be notified immediately of the presence of any deteriorated 

LBP present in the unit being examined.

• The Contractor shall visually examine and document the absence of visible dust in all 

rooms and on all surfaces treated, including any observed tracking from non-work areas 

to the cleaned areas subject to the clearance inspection. The Contractor shall visually 

examine and document the absence of all waste and debris, including paint chips 

transferred from the interior to exterior areas. If the Contractor detects visible dust or 

debris, the Contractor shall immediately notify the Contracting Officer to ensure that the 

Lead Hazard Control Contractor repeats the cleaning process prior to the collection of 

clearance samples.

• The Contractor shall visually examine and document the visual absence of LBP chips 

from the work areas on the soil following exterior lead-hazard control work. The visual 

examination shall determine whether paint chips are present along the drip line or next to 

the foundation, below the treated exterior surface. If paint chip debris is present, the 

Contracting Officer shall be notified to ensure that the Lead Hazard Control Contractor 

removes the paint chips using a HEPA vacuum, prior to proceeding with clearance. All 

horizontal surfaces in the living area closest to exterior lead hazard control treatments 

shall be visually examined to document that they are free of visible dust and debris.

The Contractor shall not collect clearance samples until the visual examination results are acceptable. 

The visual examination results and conclusions shall be documented by filling out Form 1 (Figure C-1, 
EP 1110-1-29

31 Aug 01

A-16

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

by 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. [One source of spiked samples meeting the 

QA/QC requirements is listed on the AIHA web site: http://www.aiha.org] The Contractor shall obtain 

from the commercial source, 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.

NOTE: The analytical data acceptance criteria for lead hazard identification and control 

samples provided in Table B-1 (Appendix B) have been adapted from the LQSR, 

Revision 2.0 (August 1996), Table A-1, Section 10-Quality Assurance and Quality 

Control. Table B-1 must be verified (and updated as needed) as a part of the SOW 

editing process by contacting the EPA NLLAP Program Manager (call the EPA Hot 

Line at 1-800-424-LEAD). Any time laboratory data are reviewed for acceptability, 

the current revision of the LQSR must be consulted to make required changes to Table 

B-1.

******************************************************************************

The Contractor shall review all project data collected during the clearance assessment and verify that 

the data was collected in accordance with the DQOs. 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 Clearance Sampling Plan throughout the performance of 

the assessment.

2.3.3.1 Field 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 μg/wipe of 

background lead shall render the entire container of bulk packed wipes contaminated and disqualify the 

represented wipes for field use. (See AIHA web site for a list of wipe venders meeting ASTM Method 

E 1792 criteria).

2.3.3.2 Laboratory QA and QC (QA/QC) Verification.

******************************************************************************

NOTE: The Contractor must choose the most advantageous technique to provide extra 

samples to the laboratory should additional samples be required by the laboratory to 

replace sampling or QA/QC data lost due to laboratory mistakes. The Government is 

not liable for cost of additional sample collection due to laboratory mistakes, Contractor 

collection problems, or chain-of-custody errors.

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 and soil samples) determined at concentrations equivalent 

to [ ] μg/ft2 for dust wipe samples and [ ] μg/g 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 LQSR parameters listed in Table B-1, Appendix B. Spiked samples submitted to the 

laboratory 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 specified in Table B-1, Appendix B. If the laboratory fails to obtain spiked sample 

results within the specified error limits:

a. Two more spikes of the same matrix shall be sent immediately to the laboratory for 

analysis.

b. 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 a 

destruction or loss of data, or failure to report results on any samples submitted.

Certified Risk Assessor An individual who has been trained by an accredited training program, as 

defined by this section, and certified by EPA pursuant to §745.226 to 

conduct risk assessments. A risk assessor also samples for the presence of 

lead in dust and soil for the purposes of abatement clearance testing. (40 

CFR 745.223)

Chain-of-Custody Procedures implemented to ensure a trail of accountability for samples from 

the time of collection to delivery at the laboratory including the forms used to 

implement the procedures.

Child Occupied Facility A building, or portion of a building, constructed prior to 1978, visited 

regularly by the same child, 6 years of age or under, on at least two different 

days within any week (Sunday through Saturday period), provided that each 

day’s visit lasts at least 3 hours and the combined weekly visit lasts at least 6 

hours, and their combined annual visits last at least 60 hours. Child-occupied 

facilities may include, but are not limited to, day-care centers, preschools and 

kindergarten classrooms.

Common Area A portion of a building that is generally accessible to all occupants. Such an 

area may include, but is not limited to, hallways, stairways, laundry and 

recreational rooms, playgrounds, community centers, garages, and boundary 

fences. (40 CFR 745.223)

Component or Building 

Component

Specific design or structural elements or fixtures of a building, residential 

dwelling, or child-occupied facility that are distinguished from each other by 

form, function, and location. These include, but are not limited to... (40 CFR 

745.223). 

Contracting Officer To be interpreted to mean the Contracting Officer, the Contracting Officer 

Representative, or the Contracting Officer Technical Representative 

Data Quality 

Objectives

The 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. See EM 200-1-2 Appendix 

G DQO Attainment Verification Worksheet for further refinement of the 

DQO definition.

Double-Blind Sample For the purposes of this SOW, this refers to a quality control 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 

quality control sample.

Encapsulant A substance that forms a barrier between lead-based paint and the 

environment using a liquid-applied coating (with or without reinforcement 

materials) or an adhesively bonded covering material. (40 CFR 745.223)

Enclosure The use of rigid, durable construction materials that are mechanically fastened 

to the substrate in order to act as a “dust tight” barrier between lead-based 

paint and the environment. (40 CFR 745.223)

HALO The Army’s Hazardous Asbestos and Lead Optimal Management System, 

which is an electronic management system designed to track lead hazards and 

actions taken in response to identified lead hazards.

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 (5000ug/g or 5000 

ppm) by weight. (40 CFR 745.223) 

Lead-Based Paint 

Hazard

Any condition that causes exposure to lead from lead-contaminated dust, 

lead-contaminated soil, or lead-contaminated paint that is deteriorated or 

present in accessible surfaces, friction surfaces, or impact surfaces that would 

result in adverse human health effects. 

Lead-Contaminated 

Dust

Surface dust that contains an area or mass concentration of lead at or in 

excess of levels defined in Table A-1 of this SOW.

Lead-Contaminated 

Soil

Bare soil that contains lead at or in excess of levels defined in Table A-1 of 

this SOW.

Lead Hazard Control 

Treatment

In residential lead-based paint hazard control work, any method designed to 

control lead-based paint hazards. Treatment includes interim controls, 

abatement, and removal. Examples include paint film stabilization, friction and 

impact surface treatments, dust removal using standardized cleaning 

techniques, soil covers, building component replacement, enclosure, paint 

removal, or soil removal.

μg/ft2 Micrograms per square foot

μg/g Micrograms per gram (parts per million on mass/mass basis)

MS/MSD Matrix spike/matrix spike duplicate

Permanently Covered 

Soil

Soil which has been separated from human contact by the placement of a 

barrier consisting of solid, relatively impermeable materials, such as pavement 

or concrete. Grass, mulch, and other landscaping materials are not 

considered permanent covering. (40 CFR 745.223)
EP 1110-1-29

QA Quality assurance defined by NLLAP as an “integrated system of activities 

involving planning, quality control, 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 Revision 2.0 

(August 1, 1996))

QC Quality 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 

Revision 2.0 (August 1, 1996))

Recognized Laboratory An environmental laboratory recognized by EPA pursuant to TSCA section 

405(b) as being capable of performing an analysis for lead compounds in 

paint, soil, and dust. (40 CFR 745.223)

Rinsate Blank A sample of “used” cleaning fluid rinse solution, also called equipment blank. 

Rinsate blank examples include a final rinse of the device used to collect soil 

or the final rinse to clean a scoop used to collect soil samples. The rinsate 

blank is used in rinsing collection equipment prior to use to monitor possible 

cross contamination. The rinsate blank goes through all steps in the analysis 

including the digestion. (EPA, 757-R-92-006, May 1993)

Target Housing Any housing constructed prior to 1978, except housing for the elderly or 

persons with disabilities (unless any on or more children age 6 years or 

younger resides ore is expected to reside in such housing for the elderly or 

persons with disabilities), or any 0 bedroom dwelling (40 CFR 745.223).
