c. Asbestos Training. When the Asbestos

Hazardous Emergency Response Act (AHERA)

was reauthorized as the Asbestos Hazard

Reauthorization Act (ASHARA) it mandated

specific training requirements for activities carried

out in private and public buildings as well as

schools. Specific training requirements for

inspectors, management planners, project

designers, contractors’ supervisors and workers

are found in the EPA Model Accreditation Program

EPA agreement states may have more stringent

requirements. Ensure appropriate requirements

are included where necessary for the type of

asbestos related activity to be performed. *

d. Building Occupancy. According to Army policy,

asbestos should be abated during periods when

area occupancy is minimal or prohibited: however,

project phasing or other critical factors may cause

buildings to be occupied during abatement. If

abatement must be scheduled while the building is

occupied, the designer must investigate the

following items before developing the contract

specifications.

(1) The ability to install critical barriers that

prevent access into and the exchange of air flow

from the abatement-regulated work area to the

occupied areas.

(2) The ability to install ventilation systems

that will continuously maintain a negative pressure

within the contained abatement work area and

provide an air change rate of at least four or more

air changes per hour within the abatement area,

thereby augmenting pressure differential between

the abatement area and the occupied area. Air

exchange rates must be calculated for the

regulated work area in order to

ABATEMENT DETAIL SHEETS 

1. PURPOSE. This pamphlet provides asbestos abatement Guideline Detail Sheets (Setup and Response Action) 

that will be used in conjunction with Corps of Engineers Guide Specification for Military Construction CEGS 

02080, Asbestos Abatement. 

2. APPLICABILITY. This pamphlet applies to all HQUSACE/OCE elements and all U.S. Army Corps of Engineers 

commands (major subordinate commands, district commands, laboratories, and field operating activities) 

having civil works and/or military program responsibility. 

3. CONTENTS. This pamphlet is divided into three primary parts. Part 1, ASBESTOS ABATEMENT DETAIL 

SHEET INSTRUCTIONS, (pages l-30) provides guidance to specifiers and designers on how to select, modify, 

and use the detail sheets in the preparation of asbestos abatement solicitations. Part 2, SETUP DETAILS, 

(pages 31-60) contains a series of detail drawing sheets with instructions that identify the proper containment 

and controls to be employed in support of individual abatement work tasks. One or more setup detail sheets 

are required for each defined abatement work task and are directly dependent upon the required response 

action detail sheet selected for that work task. Part 3, RESPONSE ACTION DETAILS, (pages 61-l 36) contains 

a series of detail drawing sheets with instructions that identify the abatement method to be employed 

(removal, encapsulation, encasement, enclosure, or repair) and the item to be abated (for example, removal of 

acoustical wall plastic on masonry). Only one response action detail sheet will be selected for each abatement 

work task. Each response action detail sheet refers to the appropriate setup detail sheets that are to be used to 

protect, contain, and control during the performance of the work task. 

4. USE OF DETAIL SHEETS. Asbestos abatement in CEGS 02080 entails the removal, encapsulation, 

encasement, enclosure, and repair of friable and nonfriable asbestos-containing materials. The series of detail 

drawing sheets must be used in conjunction with the CEGS 02080 in order to identify specific methods of 

abatement, containment, and control required during the performance of abatement work tasks. These detail 

sheets take into account all identifiable abatement work tasks that might be requested by Corps of Engineers’ 

customers. Specifiers and designers must select the appropriate detail sheets and modify, as necessary, to fit 

the unique conditions of each defined abatement task, and then append the selected sheets to asbestos 

abatement solicitations for use by the Contractor.

5. BACKGROUND: GUIDELINE 

DEVELOPMENT. 

Historically, asbestos abatement, design has 

primarily used written specifications for detailing 

both the scope of work and abatement 

technologies. As a result, contract documents 

were lengthy and difficult to follow. Therefore, 

techniques were modified in order to: 

a. Reduce specification content by graphically 

depicting abatement techniques. 

-l- 
EP 1110-l-11 

Change 1 

b. Present detail sheets of abatement 

techniques common to many response actions. 

c. Provide as much information as possible on 

the detail sheets so that project specific variations 

can be developed by editing the sheets. 

d. Provide a manageable process for guide 

specifications by covering several different 

abatement methods for both friable and nonfriable 

asbestos-containing material (ACM). 

The detail sheets provided in this EP are the 

product of the combined practical experience of 

numerous professional design and management 

sources and must be used in conjunction with 

CEGS 02080. 

6. RELATIVE HAZARD AND RISK 

ASSESSMENT. 

The purpose of asbestos abatement is to protect 

building inhabitants, nearby receptors, and the 

environment from exposure to and contamination 

from asbestos fibers. Therefore, before 

establishing minimum control methods based on 

relative hazards, the designer must evaluate the 

potential for the release of asbestos fibers into the 

indoor and outdoor environment during abatement 

a. Friability. 

(1) The most common hazard of assessment 

factor is the friability of ACM. The Environmental 

Protection Agency (EPA) through the National 

Emissions Standards for Hazardous Air Pollutants 

(NESHAP) for asbestos (40 CFR Part 

* 61, Subparts A and M) and EPA AgreementStates implementing NESHAP require strictly 

controlled response actions for all friable ACM. 40 

* CFR Part 61, Subparts A and M. CEGS 02080; 

and ENVR-EP Memorandum, Policy Guidance on 

Interpretation of Revised EPA Asbestos Rule 

Affecting Demolition and Renovation of Buildings, 

provide detailed guidance relative to friability 

designation. Controlled removal of friable ACM is 

normally carried out using wet techniques. EPA 

Publication No. 340/l-90-019, AsbestoslNESHAP 

Adequately Wet Guidance, provides specific 

guidance regarding adequately wet requirements 

of the revised NESHAP standard. 

(2) In addition, NESHAP requires 

preconstruction surveys and assessments for 

planned demolition and/or renovation actions. 

Those surveys and assessments are particularly 

relevant to demolition and/or renovation actions. 

Those surveys and assessments are particularly 

relevant to demolition and/or renovation abatement 

projects involving nonfriable ACM. NESHAP 

defines two categories of nonfriable ACM. 

Category 1 nonfriable ACM includes resilient floor 

covering (including ACM floor tile), asphalt roofing 

materials, packing and gaskets. Category 2 

nonfriable ACM includes all other nonfriable ACM, 

such as asbestos cement roofing tiles, siding, 

transite board, etc. If specific survey and 

assessment decision criteria in the NESHAP at 40 

CFR Part 61, Subpart M, are met, categories 1 and 

2 nonfriable ACM may be left in place during 

demolition projects. 

(3) When planning customer 

abatement procedures that involve demolition 

andlor renovation of nonfriable ACM, the designer 

must consult with the following before including 

nonfriable ACM in or excluding nonfriable ACM 

from abatement documents: 

(a) NESHAP asbestos standards. 

(b) State and local requirements (both 

regulatory and local jurisdiction landfill). 

(c) Army guidance on this subject (ENVR-EP 

Memorandum, Policy Guidance on Interpretation of 

New EPA Asbestos Rule Affecting Demolition and 

Renovation of Buildings). 

(d,l Installation guidance on this subject. 

(e) Customer requirements. 

(f) OSHA Asbestos Standard 29 CFR Part 

1926.1101. * 

b. OSHA Construcfion. OSHA in 29 CFR Part 

1926.1101 has established specific exposure and 

target risk activities to include Categories I, II, III 

and IV tasks. Requirements in this OSHA 

regulation, to include state requirements which 

may be more stringent, will have a significant 

impact on the manner in which a project is planned * 

.2- 
EP 1110-l-11

Change 1

* and designed. Planners and designers shall

ensure the appropriate requirements are

considered in abatement specifications for

individual projects.

c. Asbestos Training. When the Asbestos

Hazardous Emergency Response Act (AHERA)

was reauthorized as the Asbestos Hazard

Reauthorization Act (ASHARA) it mandated

specific training requirements for activities carried

out in private and public buildings as well as

schools. Specific training requirements for

inspectors, management planners, project

designers, contractors’ supervisors and workers

are found in the EPA Model Accreditation Program

(MAP) in 40 CFR Part 763, Subpart E, Appendix C.

EPA agreement states may have more stringent

requirements. Ensure appropriate requirements

are included where necessary for the type of

asbestos related activity to be performed. *

d. Building Occupancy. According to Army policy,

asbestos should be abated during periods when

area occupancy is minimal or prohibited: however,

project phasing or other critical factors may cause

buildings to be occupied during abatement. If

abatement must be scheduled while the building is

occupied, the designer must investigate the

following items before developing the contract

specifications.

(1) The ability to install critical barriers that

prevent access into and the exchange of air flow

from the abatement-regulated work area to the

occupied areas.

(2) The ability to install ventilation systems

that will continuously maintain a negative pressure

within the contained abatement work area and

provide an air change rate of at least four or more

air changes per hour within the abatement area,

thereby augmenting pressure differential between

the abatement area and the occupied area. Air

exchange rates must be calculated for the

regulated work area in order to

-2a-
EPlllO-1-11 

15JUL92 

ensure that air flows into the containment at all 

times. 

(3) The reexamination of fire evacuation 

routes for compliance with local fire codes. 

(41 The ability to safely access building 

service areas such as electrical panels, rest room 

facilities, and heating, ventilating, and 

air-conditioning systems. 

(51 The ability to readjust building 

air-handling systems for isolation of airflow 

into/from the abatement area. 

(61 The need for altered occupant travel 

paths and/or temporary facilities. 

(71 The ability to provide security during and 

after daily abatement activities. 

(81 The development, with the customer, of 

an occupant awareness program, including a 

description of the actual project work. 

7. RESPONSE ACTION OPTIONS. 

a. General. Asbestos abatement is achieved 

through the appropriate selection of the following 

five accepted techniques: 

(71 Removal. 

121 Encapsulation (bridging, penetrating, and 

combination). 

(3) Encasement. 

(41 Enclosure. 

(5) Repair. 

The designer will consult with the customer and 

evaluate existing conditions of the ACM in order 

to identify all abatement work tasks and 

determine which abatement technique will be 

specified for each identified abatement task to be 

completed. 

b. Removal. 

(7) Of all available abatement techniques, 

removal offers-the most satisfactory long-term 

solution. However, cost and the potential for ’ 

spreading contamination during removal are major 

considerations. For information about the adverse 

effects of removal abatement projects, the 

designer should review EPA Publication NO. 

20-T-2003, Managing Asbestos In Place, which 

describes in-place management versus WnOVal. 

(2) Many response action details for the 

removal of ACM are presented herein. 

c. Encapsulation. The many types of 

encapsulants fall into two prime categories: 

bridging encapsulants and penetrating 

encapsulants. For friable ACM, either type has a 

narrow range of application possibilities as an 

abatement strategy, particularly interior ACM. 

Consequently, encapsulation should be limited to 

those situations where friable ACM is extremely 

difficult to reach or is relatively thin in depth. If 

encapsulation is used, the designer must ascertain 

that the friable ACM has sufficient strength to 

support itself with the added weight of the 

encapsulant. Furthermore, many encapsulants will 

reduce the effective fire rating; therefore, if the 

friable ACM is fire rated, critical selection of the 

encapsulant should include the effect on the fire 

rating. For nonfriable ACM, a broader spectrum of 

application exists; its use on durable and exterior 

building products is common. 

(71 Bridging Encapsulants. Bridging 

encapsulants are characterized by their ability to 

span interstitial spaces and provide a superficial 

seal. Also, because of their high solids content, 

these encapsulants commonly provide 

high-temperature resistance as well. Bridging 

encapsulants are recommended for application on 

plaster, stucco, and wall paneling only. Bridging 

encapsulants are normally applied by airless-spray; 

although palm-grade encapsulant is trowel 

applied. Palm-grade bridging encapsulants, 

however, are recommended for application only 

on tank and boiler breeching or boiler and pipe 

gaskets. 

(2) Penetrating Encapsulants. 

(al Penetrating encapsulants have a low 

solids content and reduce the natural surface 

tension of the asbestos fibers, thereby aiding 

absorption. They penetrate beyond the surface of 

the ACM and bind the asbestos fibers into a 

relatively hard mass. Silicon-based penetrating 

encapsulants develop extremely low surface 

-3- 
EP 1110-l-11 

15 JUL92 

tension because of their chemical similarity to 

asbestos, but their use should be limited to 

encapsulating acoustical materials in place and 

asbestos-contaminated soils found in crawl 

spaces or pipe trenches. 

(61 Lock down encapsulants are 

penetrating encapsulants designed to lock residual 

asbestos to the surface from which the ACM was 

removed and the polyethylene sheeting in the 

containment area. These encapsulants, however, 

dry into a clear, glossy surface that may interfere 

with the bonding of new, asbestos-free 

replacement materials. 

IcJ Removal encapsulants are a type of 

silicone-based penetrating encapsulant that do not 

have curing agents in their formulation, but 

instead keep the ACM wet-a characteristic 

particularly helpful in reducing ACM fiber release. 

13) Combination encapsulants. Combination 

encapsulation involves the sequential application 

of both a penetrating and then a bridging 

encapsulant. Repair of asbestos cement roofing 

panels or wall and ceiling plaster are the only 

recommended uses. 

(41 High-temperature encapsulant. If 

encapsulants are to be used for a 

high-temperature application, such as a boiler 

gasket, a high-temperature encapsulant 

(2,000 OF, 1,100 OC,) should be specified. If a 

low-temperature encapsulant is used for a 

high-temperature application, it could result in 

toxic organic emissions and asbestos release. The 

manufacturer’s data sheet can be used to confirm 

the temperature rating of the encapsulant. 

d. Encasement. Encasement is an abatement 

technique involving a two-step process. First, the 

ACM is encapsulated by spraying a penetrating 

foam onto the ACM. Next, after the foam has 

cured, a plastic coating, which cures into a hard 

protective coating, is sprayed onto the foam. If 

encasement is chosen, the fire rating must be 

assessed and the ability of ACM to carry the 

additional weight of the foam and protective 

coating must be determined. If the ACM is unable 

to support the added weight, anchors can be 

installed or an analysis of the capability of the 

protective coating to bridge between support 

points can be made. Encasement techniques are 

recommended only for in situ abatement of 

spray-on fireproofing and thermal insulation and 

for hot water storage tanks exposed to weather. 

e. Enclosure. The enclosure of ACM involves 

constructing a permanent, airtight, impermeable 

barrier surrounding the ACM. Normally, studs are 

first installed around the ACM without disturbing 

it. Next, polyethylene is fastened to the studs, 

and all perimeter edges and points are sealed with 

duct tape. Finally, asbestos-free plaster board is 

attached to the studs. Enclosure should only be 

used when small amounts of ACM are involved or 

when access to the ACM is so restricted that a 

major component of the building would otherwise 

have to be demolished in order to complete the 

abatement. 

f. Repair. This technique is used to re-establish 

the integrity of ACM that has deteriorated to a 

point where the potential for ACM release exists. 

Repair as an abatement action is principally 

directed toward small areas of nonfriable ACM. 

Friable ACM, however, can be repaired where 

removal is not an acceptable alternative. 

Furthermore, this technique can be used as a 

stop-gap measure for small, significantly damaged 

areas that are expected to be a part of a more 

permanent abatement action in the future. 

8. ABATEMENT DECISION ALTERNATIVES. 

Before asbestos abatement begins, the work area 

must be prepared in a manner that will protect 

human health and the environment. Since the 

disturbance of ACM generates airborne asbestos 

fibers that may remain suspended in the air for a 

long time and migrate to other areas of the 

building, work area preparations must be designed 

to contain fibers during the entire abatement 

process. Fufihermore, the preparations protect 

interior finishes, equipment, fixtures, etc., from 

water damage or asbestos contamination, and 

also help reduce final cleaning procedures. 

a. Containment Alternatives. The designer must 

decide the extent of the protection needed for a 

specific response action. The items to be 

considered are (1) the relative risk of the 

-4- 
EP 1110-l-11 

Change 1 

alternatives, (2) the degree of protection 

necessary, and (3) the amount of protection the 

alternative provides. The five basic setup 

alternatives are listed in (1) through (5) below. The 

first four alternatives are primarily for interior 

abatement work; however, situations may occur 

where they could be applied to an exterior 

response action as well. 

(1) Full-scale contaminant areas (sheets 2,3, 

and 4). 

(2) Small-scale, short-duration abatement 

areas (sheet 10). 

(3) Mini contaminant areas (sheets 5, 6, and 

7). 

(4) Modified contaminant areas (sheet 21). 

(5) Exterior abatement areas. (These are not 

defined by a containment area sheet, but are 

identified on individual Response Action Detail 

(Sheets). 

b. Alternative Requirements. 

(1) Each containment alternative has many 

varitations, since each abatement project presents 

its own unique requirements. 

(2) One such requirement is abatement area 

sizing. Sizing is based upon site-specific data and 

requirements. For example, a large abatement 

area can be subdivided into small containment 

areas. As each containment area is completed, 

critical barriers can be installed over the access 

way of the completed containment area, thereby 

isolating it from the unabated areas. When 

abatement is complete, the air can be cleared for 

the enitre abatement area, thereby minimizing 

cost. (For air clearance, however, the areas must 

be contiguous). 

(3) Sizing may also be affected by economic 

analysis. For example, the construction of a 

bulkhead would probably shrink the size of the 

abatement area, thereby reducing the size of the 

high-efficiency particulate air (HEPA) filtered fan 

unit, the amount of plastic installed and disposed, 

and the decontamination time. Sizing may also be 

affected by phasing considerations. 

(4) In essence, area sizing and other 

requirements of an abatement area can vary 

widely: choosing the appropriate variation depends 

upon the good judgement of all parties involved. 

9. WORK AREA CONTAINMENT. Airborne 

asbestos fibers are contained within the work area 

during abatement by the installation of 

polyethylene sheeting or strippable coatings on 

walls, floor, and/or ceiling. 

a. Full-Scale Containment 

(1) Basic. Full-scale containment is used for 

large projects involving significant fiber release 

caused by the quantity and/or friability of the ACM 

and if the environmental hazard and personal risk 

is high. (See sheets 2, 3, and 4). Full-scale 

containment involves the following items: 

(a) The protection of all non-ACM surfaces in 

the work area. 

(b) The blocking of all openings, penetrations, 

passage ways, and critical barriers into and out of 

the work area with polyethylene or rigid 

impermeable material. 

(c) Material load-out units, 

(d,J Personnel decontamination units. 

(e) HEPA-filtered air exhaust. 

(0 High-level of personal protection. 

(2) Variations. Under certain conditions, full 

scale containment may deviate from the items 

listed in paragraph (1) above. Take, for example, 

an abatement project response action requiring the 

removal of vinyl asbestos tile covering 6,000 

square feet in a gymnasium. A comprehensive 

survey and assessment shows the floor tile is in 

poor condition and friable according to EPA 

NESHAP asbestos rule. The vinyl asbestos tile is 

very brittle (crumbling) and worn. Because of 

previous repairs, the floor looks like a patchwork 

quilt. The vinyl asbestos tile adhesive also 

contains asbestos. For this situation, both walls 

-5 
EP 1110-l-11 

Change 1 

20 SPp 97 

and ceiling are to be protected, and all of the 

normal protection features are to be applied. 

Because the ceiling in the gymnasium is 30 feet 

high, the Contractor has quoted an alternative 

proposal in order to comply with all of the design 

provisions (including critical barriers), except the 

polyethylene will be installed on the walls up to a 

height of only 6 feet. The Contractor will use 

flooding for tile removal and an organic material for 

adhesive removal. This deviation is an acceptable 

and practical response action if upon completion, 

the Contractor cleans all wall and ceiling surfaces 

above the polyethylene, including lights, 

backboards, stage, seating, scoreboards, etc. 

Final air clearance will provide evidence of the 

Contractor’s success. 

* b. Small-Scale, Shorf Duration Abatement 

(Rescinded) 

c. Mini-Containment. 

(1) A mini-containment area provides an 

airtight enclosure around either a low-or highhazard work area that is of limited size (see detail 

sheets 5.6, and 7). Mini-containment limits the 

spread of asbestos fibers to a small area rather 

than an entire room, and offers a quick and 

relatively inexpensive enclosure. 

(21 The mini-containment area is constructed 

with a small compartment serving as an air lock 

that prevents the release of contaminated air to the 

“clean side.” The abatement worker wears two 

sets of protective clothing. Before leaving the work 

area, the worker must vacuum the outer protective 

suit, remove it, and place it in a disposable bag. 

Then the worker steps into the air lock, where a 

clean bucket of water has been placed, and wet 

wipes the respirator and face and hands with a 

damp rag. Next the worker removes the respirator 

and places it in a clean plastic bag. Finally, 

wearing the inner suit, the worker proceeds to a 

shower located somewhere else. These personnel 

decontamination procedures generally, require the 

following items, as a minimum: 

-6- 
EP 1110-l-11 

15 JUL92 

(al HEPA vacuum. 

(bJ Critical barriers. 

(cl Full facepiece, negative pressure, 

air-purifying respirator. 

(dl Protective clothing. 

(e) Access to a shower or a three-stage 

decontamination unit. 

/3) The mini-containment area can be applied 

to almost all interior response actions that are 

limited in scope. For example, a roof leak caused 

4 square feet of wall plaster in a hallway to 

become crumbly and in need of repair. The plaster 

contains 5-percent chrysotile. The adjacent wall 

surfaces are painted and in good condition. In 

analyzing the needs of the response action, it was 

determined that only a mini-containment area was 

required. The damaged, friable plaster would be 

removed with a chisel, a brush, wet techniques, 

and a HEPA vacuum. It was estimated that 

removal of the damaged plaster and installation of 

new plaster would not exceed 4 hours (after 

installation of the mini-containment enclosure). 

After completing the response action work, the 

worker followed the predetermined personnel 

decontamination procedures at the enclosure. 

d. Modified Containment Areas. 

(1) Modified containment procedures are 

used only for low-hazard applications (see sheet 

2 1). These procedures generally require the 

following items as a minimum: 

Ial HEPA vacuum 

(b) Local exhaust HEPA filtered ventilation 

unit. 

(cl Critical barriers. 

(d) Negative pressure, air-purifying 

respirator. 

(e) Protective clothing. 

(f) Access to a shower. 

(2) Modified containment application is 

limited to response actions where nonfriable 

materials can be removed intact, for example, an 

asbestos cement tabletop or partition. Other 

projects that would qualify are easily contained 

operations, such as glove bags. Furthermore, 

modified containment procedures can be applied 

to the encapsulation of small, low-hazard items 

such as flange and boiler gaskets, which are 

virtually nonfriable because of the relatively small 

surface area exposure and compressive 

containment. 

(31 The removal of category 2 nonfriable 

asbestos-containing fiberboard or drywall panels 

also exemplifies the use of modified containment 

procedures. Critical barriers, along with a 

HEPA-filtered ventilation system that recirculates 

the air within the work area, are installed. 

Polyethylene sheeting is not placed on walls, since 

the wall material is to be removed, but the 

sheeting is placed on the floor beneath the work 

area. A respirator and protective clothing are 

required. Furthermore, an air lock is attached to 

the modified containment area (except for glove 

bag operations] where workers enter, exit, and 

conduct decontamination procedures as for the 

mini-containment area. Finally, all exposed 

workers should also take a shower immediately 

upon completion of abatement-related work 

activities. 

e. Exterior Abatement Areas. 

(1) Response actions to building exteriors 

commonly involve the noncontainment removal of 

category 1 and 2 nonfriable ACM, such as roofing 

and siding. If done carefully, the probability of any 

fiber release can be minimized, provided the 

material does not become friable, that is, 

crumbled, pulverized, or reduced to powder, 

during the removal. Simple breakage during 

removal does not mean that the abatement must 

be conducted under containment. If fiber release 

can be controlled by keeping the ACM nonfriable, 

then the need for a containment area and most of 

the associated work restrictions is unnecessary. 

(21 When work occurs in an unconfined 

outdoor air space, access to the work area must 

be controlled. A boundary zone extending 30 to 

40 feet beyond the work area must be delineated 

(see sheet 11). Furthermore, all workers should 

wear, as a minimum, a negative pressure, 

air-purifying respirator and breathable protective 

clothing. Workers should also shower immediately 

-7- 
EP 1110-l-11 

15 JUL 92 

after completion of work. The Contractor’s 

asbestos hazard abatement plan will specify 

personal protection and decontamination facility 

requirements for exterior asbestos abatement 

actions. 

f. Glove Bag Operations. The glove bag 

provides an airtight enclosure around the work 

area, enabling an abatement worker to remove or 

repair ACM within a contained area (see sheet 

101. A glove bag provides safe removal of ACM 

without the expense of a full-scale room 

containment. When a glove bag is used, the 

immediate area must be isolated in order to 

restrict access, and critical barriers must be 

installed (see sheet 21). A HEPA-filtered vacuum 

unit supporting the glove bag operation is 

required. Also, the glove bag may be kept under 

negative pressure in order to prevent the spread 

of asbestos if the glove bag leaks. Finally, placing 

a (nonducted) HEPA-filtered exhaust system in the 

area of the glove bag operation can help control 

an accidental fiber release from spreading beyond 

the established work area. 

10. RESPIRATORY PROTECTION. 

a. Personal Air Monitoring. OSHA requires that 

the type of respirator used by the worker be 

determined by personal air monitoring that 

quantifies fiber content in the environment where 

the individual works. The fiber content is 

determined by collecting air samples in the 

worker’s breathing zone. The samples are taken 

by a low-volume, battery-powered pump attached 

at the waist on the worker’s belt and connected 

via polyethylene tubing to a filter cassette 

connected to the worker’s clothing at the 

breathing zone. Constant air monitoring 

establishes a time-weighted average and ensures 

that worker exposure is kept below acceptable 

levels for a given respirator. The responsibility for 

personal air monitoring is the abatement 

Contractor’s. 

b. Respirator Types and Protection Factors. 

(7) Detail Sheet 12 describes the respirator 

types required under various airborne asbestos 

fiber concentrations. Protection factors take into 

consideration that any respirator functioning under 

negative air pressure depends solely upon the seal 

between the mask and the face. Since that seal is 

mechanical and likely to leak, the protection factor 

is appropriately lower for standard half-mask and 

full facepiece respirators than for powered 

air-purifying or pressure-demand supplied air 

respirators operating under positive pressure so 

that leakage is always outside the breathing zone. 

(2) Under no circumstances are single-use 

disposable dust masks to be used. The minimum 

level of respiratory protection is the 

half-facepiece, negative pressure, air-purifying, 

dual cartridge (HEPA-filtered) respirator, regardless 

of the type of ACM. Table 1 indicates OSHA 

protection factors for various types of respirators. 

Maximum-use concentrations are based on a 

proposed OSHA standard of 0.1 fiber per,cubic 

centimeter (i.e., 0.1 x 10 = 1 fiber/cc). 

11. GUIDELINE APPLICATION: PREPARATION OF 

CONTRACT DOCUMENTS. 

a. Guideline Detail Sheet and CEGS 02080 

Development and Use. The detail sheets 

presented in this EP and the CEGS 02080 were. 

developed as companion guidsiines that must be 

used together. Furthermorz, they must be adapted 

to fit the needs of specific projects. 

(7) Pictorial representations. The detail 

sheets provide sketches of desired 

construction/abatement actions-particularly 

useful as a guide for Contractors and workers. 

Also, since information presented graphically does 

not have to be included as a part of the contract 

specification, pictorial representations may very 

well be “worth a thousand words.” However, the 

sketches do not provide everything needed for 

contract documents for two reasons: First, 

graphic details must be generic enough for 

selective modifications or adaptation to project 

specific situations. Second, the number of detail 

sheets must be small enough so that designs can 

be selected reasonably quickly. 

12) Details versus CEGS 02080. There are 

many abatement requirements for which pictorial 

representations are inappropriate, from a practical

point of view. The determination of what 

information would be presented either in the 

details or in CEGS 02080 was based upon the 

identification and selection of those abatement 

procedures that were worker related (instructive 

graphics) and those that were administrative in 

nature (written specifications). In combination, the 

guideline detail sheets and CEGS 02080 

effectively respond to all applicable U.S. laws and 

regulations that can be enforced while the 

Contractor is under contract. 

(3) Roject-specific adaptation. Both the 

details and CEGS 02080 are generic and must be 

site adapted to meet project-specific 

requirements. Practical implementation of these 

guidelines will lead to the creation of 

project-specific details and specifications. 

6. Guideline-Detail Sheet Organizatiok The 

guideline detail sheets have been created using 

descriptive abatement instructions. Both the 

instructions and graphics contain enough data SO 

that the detail can be modified for specific 

projects by using manual deletion and editing 

techniques. The detail sheets are organized into 

two groups. The first group of 28 sheets, as 

shown in table 2, presents the techniques and 

information necessary to set up or prepare an 

abatement area for any response action. The 

remaining sheets, as shown in table 3, present 

specific response actions. The response action 

detail sheets are organized into three categories: 

interior architectural, exterior architectural, and 

mechanical/electrical applications. In addition, 

response action details have been segregated by 

abatement technique (removal, encapsulation, 

encasement, enclosure, repair) in table 4. 

c. CEGS 02080 Development and Use. 

(7) The information in CEGS 02080 is 

primarily technical in context but administrative in 

nature because CEGS 02080 was developed to 

support the detail sheets by providing other 

pertinent asbestos abatement information. Some 

worker-related abatement techniques, such as 

decontamination procedures, were made a

specific section, since they were common to all 

response actions and are an integral part of the 

worker-training curriculum (a fact that emphasizes 

that neither CEGS 02080 nor the detail sheets 

can be used as an independent entity). 

(21 Like the guideline detail sheets, CEGS 

02080 must be adapted to the requirements of a 

specific project, using deletion and editing 

techniques. Those techniques enhance the quality 

of the final product, since it is less likely that 

something may have been forgotten.

12. ADMINISTRATIVE CONSIDERATIONS. 

Because improper abatement may result in a 

hazard to building occupants, careful planning and 

diligent implementation of a project is essential. 

For asbestos projects, the standard contractual 

relationship between the Contracting Officer’s 

Representative (CORI and the Contractor remains 

the traditional construction overview practice. In 

addition, it is critical to foster cooperative onsite 

administration and coordination. 

a. Contracting Officer’s Representative (CO/?). 

(1) The asbestos abatement contract 

requires the COR to take a more active role than 

the traditional construction or demolition contract 

allows. According to CEGS 02080, the COR is 

responsible for monitoring contract compliance, 

accepting the Contractor’s final clearance (before 

clearance air sampling) via a thorough visual 

inspection, and normal inspection of workmanship 

and materials. 

121 Failure to properly control the asbestos 

abatement procedure can result in contamination 

outside the work area. Because of the critical 

value of onsite monitoring, the COR must be 

directly involved in the oversight of preabatement, 

abatement, and final clearance monitoring in order 

to ensure that the Contractor’s performance 

meets quality standards. Should a hazardous 

situation arise (such as fiber counts exceeding 

established criteria or loss of containment area 

integrity), the COR will stop all work, investigate 

the causes, and establish if a contamination event 

has occurred. If contamination exists, work must 

be terminated until a sampling program is 

instituted to identify the source of contamination 

and the need for decontamination. The extent of 

contamination can be determined by establishing 

a thorough visual inspection and air-sampling 

strategy (phase contrast microscopy (PCM) or 

transmission electron microscopy (TEM)). Work 

will not recommence unless air samples prove 

negative or until the affected areas have been 

decontaminated and identified deficiencies 

corrected. 

(3/ The COR’s responsibilities described 

above may be performed by a Contractor 

(independent of the abatement Contractor) who is 

hired by the Contracting Officer (CO). 

6. Contractor Requalification. The most 

effective means of ensuring high standards in 

asbestos abatement is through prequalification of 

potential bidders. All potential bidders must have 

successfully completed abatement projects similar 

in size and complexity to the project being bid on. 

A preliminary assessment of the quality and type 

of abatement projects the potential bidders have 

completed will be helpful in assessing their depth 

of experience, quality of execution, and other 

factors. All prequalifications should be reviewed 

during the bidding stage by the CO and made a 

part of the bid analysis. 

c. Preabatement Notification to EPA/State. 

Preabatement notification is a submittal 

requirement for the abatement. Per the revised 

NESHAP, each owner or operator of an ACM 

demolition and/or renovation site (covered by 

NESHAP) must, at least 10 working days before 

abatement begins, provide written notice of the 

intention to demolish or renovate. The revised 

NESHAP also requires a demolition/renovation 

notification in a format similar to figure 1. Check 

with the EPA region, the State, and the customer 

in order to determine who will submit the 

notification, the Contractor or the Government. 

d. Oversight. 

(1) Contract enforcement. Enforcement of 

the contract requirements by the COR 

encompasses both technical and administrative 

functions, including the following: 

la/ Processing the Contractor’s submittals 

as listed in the Contractor’s submittal register. 

161 Visual inspecting and monitoring of 

the Contractor’s work. Also, air sampling if 

specified in the contract. 

/cl Reviewing all Contractor’s progress 

reports and abatement daily log. 

fdl Preparing the final abatement report. 

121 Contract Submittals. The Contractor’s 

submittal register lists those items to be 

submitted to the CO (see CEGS 02080). There are 

four submittal categories: (1) those to be

submitted with the proposal, (21 those requiring 

submittal before commencement of abatement 

work, (3) those submittals that continue 

throughout the progression of the abatement 

work, and (4) final submittals. Although various 

submittals may require no action and are only for 

the record (such as the medical examiner’s 

report), the CO or COR should acknowledge 

receipt and acceptability of the documents 

submitted. 

(3/ Contract compliance. To determine 

compliance with the contract specifications 

regarding products and equipment may be a 

difficult task. The difficulty lies in the evaluation 

of’an unfamiliar product for which there is no 

similar product. To aid in evaluating such 

products, manufacturer’s data sheets and 

catalogues for the products and equipment are 

required submittal items per CEGS 02080. 

(4) Final report. A final abatement report 

provides a means for documenting the project 

history for future reference. Included in that report 

are: 

(al Project Documents. Specifications and 

copy of as-built drawings. 

(bl Contractor’s Submittals. 

(c) Daily Inspection Records. 

/d/ Final Air Clearance Reports. 

(5) Air-sampling compliance. Monitoring of 

the abatement site includes National Institute of 

Occupational Safety and Health (NIOSH) method 

7400 PCM air sampling of the ambient areas 

adjacent to but outside of the abatement area. 

The analysis of those samples will provide the 

assurance that all fiber releases have been 

contained within the abatement area and have not 

contaminated the adjacent building spaces. 

Confirmation of the PCM results by NIOSH 

method 7402 TEM is an option that the 

Contractor may employ (at the Contractor’s own 

expense) in order to verify asbestos fiber 

concentrations. 

e. Air-sampling program. A comprehensive 

air-sampling program combines (1 I preabatement 

air testing, (2) daily air monitoring, and (3) final air 

clearance in order to model or define 

environmental air quality at any given stage of the 

abatement process. For the three types of air 

samples, each has a different protocol and 

satisfies a unique purpose. 

(1) Preabatement. Just before abatement 

begins, preabatement air tests are taken by the 

Contractor or COR, as specified in the contract. 

Those tests involve gathering air samples for 

analysis by NIOSH method 7400 PCM. If the PCM 

analysis identifies a fiber count in excess of 0.01 

fibers/cc, then a sample from the same filter 

analyzed by NIOSH method 7402 TEM to confirm 

PCM results is conducted. 

(2) Abatement and Final Clearance. CEGS 

02080 requires the Contractor to implement an 

air-monitoring program meeting Federal and State 

requirements. Such an air-monitoring program is 

designed to define airborne fiber exposure levels 

of employees and guarantee good work practices, 

contaminant control, and an abated work area 

that meets final clearance airborne concentration 

limits. (See table 5 for final air clearance 

requirements). In addition, CEGS 02080 allows 

the CO the option of confirming good work 

practices by the Contractor and ensuring that 

contamination has not spread beyond the 

containment area. If the option is selected, during 

abatement activities, daily air samples would be 

taken for the COR by the Government (in-house or 

the contract industrial hygienist) in order to 

establish or confirm fiber counts inside and 

outside the containment area and at the discharge 

of each HEPA-filtered exhausting unit. The 

number of samples gathered each day depends 

upon how many containment areas are active, 

their size, and the activity occurring within. 

f. Packaging, Transportation, and Disposal. 

Fugitive asbestos fiber emissions (fibers 

accidentally released from their containment) can 

occur at any stage during abatement; the 

packaging and handling of ACM in preparation for 

or in the actual transportation and disposal of 

ACM is no exception. If the methods and 

strategies discussed in paragraphs (1) through (4) 

below are properly applied, environmental 

protection can be assured.

’ Required by CEGS 02080. 

’ Customer option upgrade. The mandatory method in EPA’s 40 CFR Part 763 requires a minimum of 5 samples per 

sbatement area and an equal number outside abatement area. Additional samples may be desirable when existing 

obstructions prevent proper characterization of the abatement area. 

(I) Packaging. The ACM must be properly 

prepared and packaged. 

/a/ Normally, before removal, the ACM 

should be thoroughly saturated with a penetrating 

encapsulant or with amended water before 

proceeding with packaging. Resaturation may be 

necessary if ACM is not packaged immediately 

after removal. 

(bl Packaging techniques include double 

bagging, double wrapping, and packing in 

polyethylene-lined cardboard boxes, polyethylene, 

or fiberboard drums. The technique selected 

depends primarily on the ACM itself. Double 

bagging should be used for soft, rounded 

materials that are less likely to puncture the 

polyethylene. Double wrapping should be used for 

large, intact ACM that would not fit into a 

polyethylene bag, for example, carpeting, 

suspended ceiling systems, partitions, and 

tabletops. Polyethylene-lined cardboard boxes 

should be used for sharp or pointed materials such 

as scrap metal, broken asbestos cement products, 

etc. Polyethylene-lined drums may be used for any 

ACM; however, their use is not recommended 

inside a containment area because of the 

decontamination and handling problems related to 

their size and weight. In addition, local regulators 

and disposal facilities may prohibit use of such 

containers. 

(21 Labels and licenses. Before any container 

is released for shipment and disposal, it must be 

properly labeled, and the Contractor must have all 

necessary licenses and permits in hand. 

(31 Transport. 

la) Waste must be transported in a 

polyethylene-lined truck or Dumpster that is 

- 20 - 
EPlllO-l-11 

15 JUL92 

completely enclosed. The vehicle should be 

placarded to indicate the type of load. The vehicle 

should be loaded by abatement workers wearing 

respirators and protective clothing. Care must be 

taken not to rupture or tear the containers. 

(b) The NESHAP requires a waste and 

shipment record similar to figure 2 in order to 

document that the waste has reached its intended 

destination. The form must be completed and 

signed by the Contractor, the transponer, and the 

disposal site operator. The data on the form 

should fully describe the ACM containers in the 

shipment, and the cargo should be confirmed by 

each signatory as the shipment is handed off. 

(4) Disposal. The most common disposal 

practice is to bury the packaged waste in sanitary 

landfills approved for asbestos waste by State or 

local authority. Trench landfills are often used to 

minimize wind dispersion. If possible the trench 

should be sloped down from grade at one end so 

that the the truck can back into the trench. All 

waste will be unloaded and positioned in 

accordance with State and local landfill authority 

requirements. Positioning may be achieved by 

carefully sliding a load off a Dumpster or dump 

bed that extends to the ground or unloading by 

hand or mechanical forklift. Workers conducting 

this task should be wearing respirators and 

protective clothing. When the entire load is 

positioned, the waste is to be covered with a 

minimum of 6 inches of uncontaminated soil 

within 24 hours. The revised NESHAP standard 

governs specific requirements for landfill disposal; 

however, State and local criteria may be more 

stringent. 

13. CONTAINMENT AREA CONSIDERATIONS. 

Environmental and access control techniques 

protect the health of workers in a hazardous 

environment and the general public from incidental 

exposure. Discussed in paragraphs a through f 

below are the techniques used to control access 

to the environment within the containment area. 

These techniques are also intended to prevent 

uncontrolled fiber releases to the outside 

environment from within the containment area. 

a. Access Control. 

(1) Barriers. A work area can be delineated 

by a variety of barriers, from yellow warning tape 

to a chain link fence, depending upon the location, 

public access, relative security, etc. Perimeter 

warning tape must always be used in combinatron 

with any other selected barriers method (see 

sheet 11). 

(2) Signs. In addition, warning signs (see 

sheet 11) must be installed at each entry point 

and at regular intervals along the established 

barrier. 

(3) Security guards. Typically, a security 

guard needs to be considered only for full-scale 

abatement projects. If the abatement area can be 

made secure during nonworking hours, then only 

a daytime guard may be needed. If the nature of 

the abatement action requires constant monitoring 

to guarantee continuous operation of the negative 

exhaust system and/or the site cannot be secured, 

then a 24-hour security guard may be required. 

6. Work Area Isolation. The degree of area 

isolation required is the prime factor of each 

abatement alternative (see paragraph 9 above). A 

work area is isolated by preventing the free 

interchange of air between clean and 

contaminated environments. In effect, an airtight 

chamber is created by overlapping polyethylene 

sheets and sealing all edges and seams to 

adjacent surfaces, using duct tape. Spray 

adhesives can be substituted for duct tape; 

however, they are more difficult to remove and 

may lift existing wall, floor, and ceiling finishes 

during removal. Spray adhesives are normally 

limited to joining and sealing polyethylene laps. 

(I) Critical barriers. As a minimum, 

polyethylene critical barriers are installed over all 

windows, doors, and other openings or 

penetrations in the walls, floor, and ceiling. The 

prime purpose of any additional polyethylene is to 

protect nonabatement surfaces from 

contamination. Depending on required building 

usage factors during abatement activities, more 

rigid critical barriers may be necessary. 

(21 Airflow barrier (air IockJ. Access into a 

work area is always through an airflow barrier

polyethylene fastened at the top and on alternate 

sides. The middle layer is fastened on the 

opposite side to that of the two outer layers. 

When the HEPA-filtered fan unit is in operation, it 

creates a negative pressure inside the 

containment area, and the three access panels are 

drawn together by the airflow, creating an air lock 

by which airflow into the work area can be 

controlled. The following suggestions will help 

prevent deterioration of the access panels from 

frequent use and create a tighter air lock: 

(al Retnforce the free-moving edges with 

duct tape. 

(b) Attach a rod weight to the bottom of 

the outer panel. 

(cl Construct flaps from reinforced 

polyethylene. 

131 Glove bags. Glove bags also isolate a 

work area; however, their use is restricted (see 

paragraphs Sb(3) and Sf above). 

c. Air-Exhausting System. 

(7) The air-exhausting system must be 

installed in all full-scale containment areas before 

abatement work can begin because this is the 

system used to contain asbestos fibers within the 

work area. This system creates a negative 

pressure within the containment area as compared 

to the outside ambient area and a pressure 

gradient through air locks. Sequential air locks are 

found between the various compartments of the 

decontamination and load-out units. Negative 

pressure must be maintained. Then if a small tear 

or breach should occur in a critical barrier or 

access way, clean ambient air would flow into the 

-24 - 
EP 1110-l-11 

15 JUL 92 

contaminated area; however, if no pressure 

differential existed, contaminated air could leak 

into the surrounding environment. 

(2) The discharge of the air-exhausting 

system must be HEPA-filtered. HEPA filters retain 

at least 99.97 percent of 0.3 micron 

monodispersed aerosol before releasing air to the 

outside environment. The preferred point of air 

discharge is to the outside of the building. If that 

is impractical, filtered exhaust air may be 

discharged within the building, but as far away 

from the containment area as possible in order to 

guarantee airflow into the containment area. 

Flexible ductwork is commonly used to channel 

the airstream to its discharge point. 

(3) As with any ventilation system, the 

entire system must be properly sized in order to 

provide the airflow needed to guarantee the 

desired pressure differential. Conventional practice 

is to specify a minimum ventilation rate of four air 

changes per hour. The number of exhaust units 

needed is determined by dividing the total airflow 

requirement by the rated capacity of the exhaust 

unit. The pressure difference between the outside 

and inside of the containment can be as low as 

0.02 inches of water pressure. Although that 

pressure differential, if maintained, will guarantee 

airflow into the enclosure, caution must be 

exercised if the building itself is pressurized or if 

atmospheric or wind conditions alter or reverse 

the negative pressure gradient. Therefore, it is 

recommended that a minimum pressure 

differential be maintained in order to ensure that 

the negative pressure gradient is such that airflow 

into the enclosure would be guaranteed if the 

containment were breached. 

d. Decontamination and Load-Out Units. Two 

types of decontamination units are usually 

required: (1) the personnel decontamination unit 

(see sheet 22) and (2) the material load-out unit 

(see sheet 20). A load-out unit does not need to 

be constructed if the volume of removed ACM is 

small or if there-is no space to construct-one. In 

such cases, the bagged ACM may be removed 

through the personnel decontamination unit. 

However, if the wrapped or containerized ACM is 

too large to carry through the personnel 

decontamination unit, then a load-out unit must 

be provided. When properly constructed and used, 

the decontamination and load-out units will ensure 

that both airborne asbestos and loose asbestos 

debris remain within the work area and do not 

contaminate adjacent areas. 

(I) Personnel decontamination unit. Thus unit 

is composed of at least three rooms: (1) the clean 

room, (2) the shower room, and (3) the equipment 

room. Upon entry, workers remove street clothes, 

put on protective clothing and respirators, and 

pass through the shower room and equipment 

room into the abatement work area. When exiting 

the work area, the workers shed their protective 

clothing in the work area, remove any additional 

clothing, shoes, etc., in the equipment room, and 

enter the shower room while wearing only their 

respirators. Street clothing is put on in the clean 

room. Prefabricated decontamination units are 

commonly used by experienced abatement 

Contractors. 

(2) Material load-out unit. This unit is used 

for the removal of bagged or containerized ACM, 

and is composed of at least two rooms: I1 1 the 

wash room and (2) the holding room. Material 

flow is through the wash room where the exterior 

of the bags, etc., are wet ‘wiped before 

temporarily storing in the holding room. When 

load-out activities are initiated, the bags, etc., are 

removed from the holding room onto an enclosed 

.truck or other approved conveyance device. 

Workers are not to use the load-out unit for entry 

into or exit from the work area. 

e. Personal Protection Program. The purpose of 

a personal protection program is to continuously 

evaluate asbestos fiber content in the abatement 

area so that the proper respirator is used and all 

other precautionary measures are taken to protect 

the workers. An effective personal protection 

program would include the following: 

(I) Respirator-fit testing. 

(21 Medical surveillance. 

(3) Respiratory selection criteria. 

(41 Protective clothing, that is, disposable 

coveralls, boot covers, gloves, and hoods. 

-25 - 
EP 1110-l-11 

15 JUL 92 

(5) Prescribed asbestos decontamination 

procedures for workers exiting the abatement area. 

16) Worker training. 

17) Appropriate practices to be used in the 

removal, handling, and disposal of asbestos. 

The sections in CEGS 02080 dealing with 

respiratory protection and worker protection have 

been prepared using appropriate procedures. The 

objective of those procedures is to provide a safe 

level of protection to all parties involved, including 

workers, supervisors, inspectors, and visitors. 

f. Cleaning and Decontamination Procedures. In 

order to protect the health of individuals who will 

reoccupy a building (including workers whoLwill 

demolish the building), the cleaning and 

decontamination of an asbestos abatement work 

area is an essential part of all abatement projects, 

regardless of the type of containment used. The 

procedures for cleaning and decontamination 

involve a series of steps that should result in the 

complete removal of both visible and invisible 

asbestos fibers. All permanent surfaces (ceilings, 

walls, and floors) and all furnishings flights, 

shelves, and miscellaneous equipment) are wet 

cleaned and/or HEPA vacuumed as many times as 

necessary to guarantee successful 

decontamination. A normal decontamination 

sequence requires three cleaning cycles, with a 

thorough visual inspection at the completion of 

the final cleaning cycle. If there is any discernible 

dust or debris found, the COR should,require 

additional cleanings. After passing a final visual 

Inspection, air samples are collected and analyzed 

for the presence of airborne asbestos fibers. 

I 7) Wet Removal Techniques. 

(a) The EPA requires all ACM to be 

wetted before removal, unless conditions warrant 

an exception (see paragraph (21 below). Fiber 

release is minimized by the interstitial attraction 

that is developed from the wetting. Wetting 

techniques apply to both friable and nonfriable 

ACM, even though minimal penetration into the 

nonfriable ACM can be expected. 

(6) Surfactants added to the water aid 

penetratjon and dispersal of the water used for 

wetting. The surfactants reduce the surface 

tension of the ACM and prevent beading, thus 

promoting the interstitial attraction. There are two 

types of surfactants: (1) amended water and (2) 

removal encapsulant. Amended water is made 

from mixing a I- to 3-percent solution of a 

inexpensive generic surfactant (such as 

50-percent polyoxyethylene ester and 50-percent 

polyoxyethylene ether) in water. A removal 

encapsulant that contains an aqueous alkali 

silicate is more expensive than amended water, 

but because it has a similar chemical composition 

to asbestos, the asbestos, in particular amosite 

asbestos (the surface tension of amosite is higher 

than other forms of asbestos), is wetted more 

readily. 

fcj When removing nonfriable ACM that 

breaks up under removal, such as plaster, stucco, 

or decorative paint, the ACM will be sprayed 

constantly. Low pressure, low velocity airless 

sprayers are used because they effectively 

atomize the wetting agent and reduce the 

possibility of fiber release from the impact zone. 

12) Dry Removal Techniques. Dry removal is 

cqnsidered extremely hazardous, since fiber 

release cannot be controlled; therefore, full 

containment must be employed. Because of the 

amount of fiber release caused by dry removal, 

supplied air respirators are recommended. 

Furthermore, because of the hazards associated 

with dry removal, the EPA requires that written 

approval be obtained before abatement begins. 

Dry removal would be used only in those 

situations where wet techniques would result in a 

greater hazard. Normally, dry techniques are used 

around electrical panels or thermally hot 

equipment that cannot be deactivated. When 

used, a local exhaust, HEPA-filtered ventilation 

and collection system will be placed as close as 

possible to the abatement activity. 

14. RESPONSE ACTION SELECTION. 

a. Options. The selection of the most 

appropriate response action depends upon the 

purpose of and the circumstances leading to the 

abatement, as determined during the site survey. 

- 26 - 
EP 1110-l-11 

Change 1 

30Sep97 

* 

The following options are available to the designer 

when selecting the most appropriate abatement 

technique for specific situation: 

(1) Removal 

(2) Encapsulation. 

(3) Encasement. 

(4) Enclosure. 

(5) Repair. 

Table 3 above lists the response action options for 

various ACM. Although all five options are 

available to the designer for the abatement of 

friable ACM, the last four are rarely used for 

demolition work. 

b. Demolition and Renovation Factors. 

(1) Demolition and renovation response actions 

are governed by the revised EPA NESHAP 

regulation and can entail either the repair or 

removal of both friable and nonfriable ACM. For 

example, if a building is being demolished and 

exterior nonfriable ACM is being removed before 

demolition, final clearance is not required. If the 

interior ACM is removed before demolition, final air 

sampling can be satisfied by PCM or as required 

by more stringent State or customer requirements. 

TEM sampling is not usually required. PCM air 

samples are required, however, since demolition 

workers would probably enter the building after 

abatement. For interior building renovations, final 

air clearance is also a requirement, since the 

space would be reoccupied for normal use. 

Normally if the ACM under the renovation is 

exterior, final air clearance would not be required, 

unless the penetration of airborne dust 

contaminated interior spaces. 

(2) According to the revised NESHAP, 

category 1 and 2 nonfriable ACM may be left in 

place during demolition if specific conditions are 

met. See Army Environmental Office ENVR-EP 

Memorandum, Policy Guidance on Interpretation of 

Revised EPA Asbestos Rule Affecting Demolition 

and Renovation of Buildings. 

(3) For demolition work, nonasbestos 

materials may have to be removed before ACM 

removal in order to reach the ACM or 

accommodate project phasing. Nonasbestos 

demolition work performed before asbestos 

abatement should be under the supervision of an 

individual trained in asbestos abatement and with 

an awareness of ACM. That individual must be 

informed of the locations of the ACM and should 

be on the lookout for other hidden ACM that may 

become exposed as demolition proceeds. 

c. Removal Factors. Complete systems, such 

as piping or mechanical equipment, may be 

removed with the ACM still attached. In such 

cases, glove bag procedures are used to remove 

the ACM where the pipe or equipment is to be cut 

or dismantled, leaving component sections as 

large as possible. Sections with the ACM still 

attached are wrapped and sealed according to 

established procedures. This method is feasible 

when systems are unsalvageable and the 

respective State does not require segregation of 

asbestos-contaminated waste before disposal. 

Removing systems with asbestos insulation intact 

will usually result in material and labor cost 

savings. However, the cost of transport and 

disposal of large components must be evaluated 

and weighed against the lower abatement cost. 

d. Decontamination Factors. 

(1) Cleaning the contaminated materials 

before disposal may be less expensive than 

preparing them for disposal as contaminated 

waste, although State regulations, labor rates, and 

cost of replacement materials for ACM will 

determine the relative economics of 

decontamination. 

(2) It is possible to wash or HEPA vacuum 

asbestos-contaminated building materials and then 

dispose of the materials as nonasbestos waste. 

Some of the most common examples are 

carpeting, curtains, ductwork, and ceiling tile. 

However, it is recommended that laboratory tests 

be made to verify the success of decontamination. 

e. Other Selection Factors. The selection of the 

most appropriate response action detail sheet 

should be made carefully, with full coordination 

with the customer. Furthermore, careful field 

observations of the situations leading to the 

response actions affect the selection of the most 

appropriate abatement detail. Also, a nonfriable 

-27- 
EP 1110-l-11 

15JUL92 

ACM that normally requires only a modified 

containment area should be inspected. Close 

inspection may reveal that the ACM is in poor 

condition and friable or would be damaged during 

removal to the point where it would be considered 

crumbled, pulverized, or reduced to powder. Then 

full-scale containment would be indicated. An 

example would be the removal of asbestos 

cement heat shields. 

15. ABATEMENT DESIGN. Paragraph 14 above 

presented guidelines for evaluating the available 

alternatives and options. This paragraph further 

refines that process. 

a. Gathering and Reviewing Data. The design 

of an abatement project starts with gathering and 

reviewing all related data and information so that 

construction documents can be prepared. 

(I) General input. Data would include 

available videotapes, photographs, floor and site 

plans, and all other information that would aid in 

establishing the response actions and 

conceptualizing the abatement design. 

(2J Military input. Data gathering would also 

include contacting the local military authorities to 

provide information about any changed conditions 

since the site survey was made. 

(3) Customer input. Significant input into the 

design process can be provided by the local 

customer, particularly regarding detailed 

information on the ACM to be abated and 

scheduling requirements. The designer will take 

the necessary steps to coordinate with the 

customer in order to obtain any necessary 

information that could help prevent changes to 

the contract during abatement. 

b. Guideline Application. Once the data is 

gathered and reviewed, the designer is ready to 

select the response action and corresponding 

setup details, edit the detail sheets and CEGS 

02080, and review various factors. 

(7) Selecting setup detail. Upon selection of 

the response action detail for the individual work 

task, use tables 2 through 5 above for identifying 

the appropriate setup details for each response 

action. If more than one setup detail applies, the 

designer must analyze the project-related data to 

determine which alternative detail is the most 

applicable. For example, if the response actions of 

a room are for the removal of plaster on an 

exterior wall (sheet 47) and removal of vinyl 

asbestos floor tile (sheet 751, of the three 

alternative setup details that could apply, the 

most appropriate one would be sheet 4. 

(2) Editing details and CEGS 02080 for a 

specific project. 

(al Both the graphics and the instructions 

of the details sheets may need to be edited to 

make them project specific. For instance, 

assuming the room has no furniture in it and the 

window wall is the exterior wall, the designer 

would delete the irregular lines on that wall, 

which designate polyethylene sheeting, along with 

any other features that do not exist, such as the 

register and exterior door. Instructions 1 and 2 for 

sheet 4 would be edited as noted below. 

(Boldfaced indicates deletions.1 

1. Establish work area so that unauthorized entry is 

prevented; see sheet 1 1. Eliminate air flow into 

containment area by isoiating all supply and return air 

ducts from mechanical system. Lock doors and 

windows not required for access. 

2. Install 6-mil polyethylene barriers over all windows, 

doors, wall openings, electrical outlets, etc. Secure 

with duct tape on all sides. HEPA vacuum furniture, 

fixtures, and equipment and r-w from or protect in 

containment area, as specified by the contract. 

Since no work is expected to be done on the 

ceiling, instruction 3 would be edited as follows: 

3. Prepare area as follows: turn off electrical power 

and r-ve light fixtures. Protect ceiling as required. 

HEPA vacuum floor and walls. 

As a final edit to sheet 4, the designer should 

transform the dashed lines representing duct tape 

to solid lines. Solid lines make the duct tape on 

the critical barriers visible rather than hidden. 

lb/ Any paragraph in CEGS 02080 

containing brackets, regardless of the text within 

the brackets, will require editing. Also, the 

designer should review and edit every instruction 

on each detail sheet and every paragraph of each 

CEGS 02080 section, deleting all unrelated, 

superfluous data and modifying where necessary 

-28 - 
EPlllO-l-11 

15JUL92 

to make both project specific. Final versions of the 

detail sheets supporting the abatement design 

drawings should be attached to the contract 

specification at table 1, Summary of Work Tasks. 

(3) Review of Factors. 

(al Air rate factors. For sheets 5 and 6, 

the volume of the containment area must be 

calculated to verify the rate of exhaust air 

obtainable from a HEPA vacuum, which is 

normally 100 cfm or less. Should the size of the 

containment area exceed the capabilities of the 

HEPA vacuum, a small capacity HEPA-filtered fan 

unit would be required and the detail modified 

accordingly. The most effective way of installing 

the HEPA-filtered fan unit in a small area would be 

to cut a window in the polyethylene, slide the fan 

unit intake up to the window, and seal the 

polyethylene sheeting to the casing of the fan unit 

with duct tape. Most of the fan unit would remain 

outside the containment area and would not 

become contaminated. 

161 Mini-Containment limitation factors. 

Mini-containment areas (sheets 5, 6, and 7) 

should be limited to small-scale, short-duration 

work or to the removal of low-hazard items. 

However, that limitation does not apply if the air 

lock (sheet 1) is replaced with a 

decontamination/load-out unit. For example, when 

the abatement action involves only a portion of a 

large room or area, the use of a bulkhead 

becomes an economic consideration for several 

reasons: I1 ) only a small portion of the area is 

exposed to contamination, (2) less polyethylene is 

used, (3) less waste is generated, and (4) a 

smaller HEPA-filtered air-exhausting fan unit can 

be used. 

(cl Structural critical barrier factors. The 

structural critical barrier (sheet 28) is a 

construction barrier that isolates the abatement 

area from nonwork areas and prevents air 

exchange between the two areas. This barrier also 

helps keep unauthorized persons out of the 

abatement area. Furthermore, this barrier can also 

serve as a volume-reducing bulkhead if used in 

conjunction with a decontamination unit 

elsewhere. 

c. Abatement Drawing Creation. 

(1) To create an abatement design, a series 

of two planimetric background drawings should be 

used. The first drawing would outline the 

abatement areas and would specify what 

response action detail sheets would apply for each 

abatement area. The second drawing would 

outline the abatement areas but would also 

superimpose the applicable setup detail sheets for 

each abatement area. For both drawings, 

construction-related notations that are an integral 

part of the abatement design must be added, for 

example, construction notes such as the following: 

1. A construction barrier shall encircle the work area. 

It shall consist of yellow warning tape attached to 

posts at 9 feet on center and strung 3 feet above 

gade. Warning signage shall be attached to the tape 

at a 46 feet spacing (see detail sheet 14). 

(2) The drawings should also include the 

following items: 

(a) Location of the decontamination and 

load-out units. 

(b) Pick-up points for electrical power and 

potable water. 

(cl Route to be taken for disposal of the 

ACM, and the location of the disposal truck. 

(d) Area for locating the HEPA-filtered fan 

unit and routing of the discharge air duct. 

(3) For small, uncomplicated projects, the 

abatement area and response action plans may be 

combined in order to reduce the total number of 

sheets. 

(41 A helpful technique for describing actual 

site conditions is the use of photographic 

sticky-back images that can be attached to a 

drawing in order to create a descriptive detail. 

With the addition of specific instructions, the 

photographic details can identify the ACM that 

will be removed, highlight the prospective site of 

the load-out unit, show how to discharge the 

HEPA-filtered exhaust air through a window, etc. 

151 If at any time during the abatement 

design process the designer identifies a building 

material that was not surveyed but is affected by 

the project, the designer should develop a bulk 

-29 - 
EPlllO-l-11 

15JUL92 

sampling program and have the bulk samples 

gathered and forwarded to the designated project 

laboratory for analysis. However, if the quantity 

of material is limited and since all materials are 

assumed to be asbestos containing until proven 

otherwise, the designer could forego sampling, 

treat it as an ACM and include it with the other 

response actions. 

16. REPLACEMENT DESIGN. This EP is directed 

toward abatement activities and does not include 

technical designs and specifications for the 

replacement or restoration of abated materials. It 

is expected that the development of designs and 

specifications for replacement will follow 

established procedures. To ensure that abated 

ACM is replaced with asbestos-free substitutes, 

the Contractor must submit the manufacturer’s 

guarantee or the manufacturer’s material safety 

data sheet as evidence that the replacement 

materials are asbestos-free. If the same 

Contractor is providing and installing replacement 

materials, documentation that replacement 

products are asbestos free should be one of the 

items in the Contractor’s submittal register. 

17. COST ESTIMATING. Asbestos abatement and 

removal cost and pricing data may be obtained 

from the Corps of Engineers Computer-Aided Cost 

Engineering Support System, Division I. The data 

are to be site adapted as applicable.
