CONCLUSIONS

In order to promote a safe and healthy work environment, the Air Force requires that asbestos-containing materials be identified and controlled.

Building 1831 (Baseline)

One non-friable miscellaneous material was observed in Building 1831. The material that tested positive for asbestos consisted of:

• Gray caulking (around window and vent frames)

At the time of the inspection, the gray caulking (around window and vent frames) appeared to be in good condition and had a potential for damage resulting in a Hazard Ranking of 1 for this material. In this condition, the material does not constitute a hazard. However, any disturbance of the material such as replacement, cutting or abrading may release fibers into the air. In order to facilitate the proper management and maintenance of the material, MWH recommends that it be included in an O&M Plan.

Building 1837

One non-friable miscellaneous material was observed in Building 1831. The material that tested positive for asbestos consisted of:

• White HVAC gasket

At the time of the inspection, the white HVAC gasket appeared to be in good condition and had a potential for damage resulting in a Hazard Ranking of 1 for this material. In this condition, the material does not constitute a hazard. However, any disturbance of the material such as replacement, cutting or abrading may release fibers into the air. In order to facilitate the proper management and maintenance of the material, MWH recommends that it be included in an O&M Plan.

Please refer to the baseline unit for asbestos containing materials

Chapter 15 Asbestos

15-1. Scope This chapter contains criteria to control and abate threats to human health and the environment from asbestos, and describes proper management of asbestos during removal and disposal.

Asbestos management and training activities will be conducted in accordance with standards set forth in the Asbestos Hazard Emergency Response Act (AHERA), Title 40, Code of Federal Regulations (CFR), Part 763, Subpart E, ―Asbestos-Containing Materials in Schools.‖ Policy requirements for a Comprehensive Occupational Health and Safety program policy are not covered in this chapter. To protect personnel from asbestos exposure, refer to DoDI 6055.1, "DoD Occupational Safety and Health Program," and DoDI 6055.5, "Industrial Hygiene and Occupational Health," and concomitant service instructions.

15-2. Definitions

a. Adequately Wet. Sufficiently mix or penetrate with liquid to prevent the release of particulates. If visible emissions coming from ACM are observed, then that material has not been adequately wetted. However, the absence of visible emissions is not sufficient evidence of being adequately wet.

b. Asbestos. Generic term used to describe six distinctive varieties of fibrous mineral silicates, including chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite. Also includes any of these materials that have been chemically treated and/or altered.

c. Asbestos-containing material (ACM). Any material containing more than one percent asbestos by weight.

d. Asbestos-containing waste material (ACWM). As applied to demolition and renovation operations, ACWM includes, regardless of its phase (i.e., liquid, solid) (a) all friable asbestos waste, (b) Category I non-friable ACM that has become friable (e.g., dust collected in dust collectors and debris produced from cutting, grinding, or shaping of asbestos products), or is in poor condition, (c) Category II non-friable ACM that becomes crumbled, pulverized, or reduced to powder by forces that acted on the material during the course of demolition or renovation operations, and (d) materials contaminated with asbestos, including disposal equipment, floor vinyl sheets, respirators, and protective clothing, etc. Wastes generated during building demolition are classified as designated wastes if ≥1% of asbestos is present, regardless of its phase (liquid, solid, or else).

e. Category I non-friable ACM. Asbestos-containing packings, mastic, gaskets, resilient floor covering and asphalt roofing products in accordance with the Asbestos National Emission Standard for Hazardous Air Pollutants (NESHAP). Category I non-friable ACM is not subject to regulation unless it (a) has been subjected to sanding, grinding, cutting, or abrading, (b) becomes friable, or (c) is in poor condition.

f. Category II non-friable ACM. Any non-friable asbestos-containing material not designated as Category I, in accordance with the Asbestos NESHAP, that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. Some examples of Category II non-friable ACM are cementitious asbestos board (transite), acoustical ceiling tiles, flex connectors, expansion joints, caulking material, and textured paint.

g. Composite sample. Multiple layers of a single core sample are composited for analysis. A composite sample does NOT combine multiple individual samples to obtain a single result.

h. Friable Asbestos. Any material containing more than one percent asbestos that, when dry, can be crumbled, pulverized or reduced to powder by hand pressure.

i. Joint compound. The material used to fill nail holes, cracks, and small spaces between sections of wallboard.

j. Multi-layered interior wall system. A system that contains multiple layers of material, any or all of which may be ACM.

k. Non-friable asbestos. A material containing more than one percent asbestos as determined using Polarized Light Microscopy (PLM) that when dry cannot be crumbled, pulverized, or reduced to powder by hand pressure.

l. Regulated asbestos-containing material (RACM). Includes (a) friable asbestos material,

(b) Category I non-friable ACM that has become friable or has been/will be subjected to sanding, grinding, cutting or abrading, and (c) Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder in the course of demolition or renovation operations.

15-3. Criteria

a. Installations will appoint, in writing, an asbestos program manager to serve as the single point of contact for all asbestos-related activities.

b. Installations will prepare and implement an asbestos management plan. Service components may elect to standardize and publish procedures that may be used as a common component for the asbestos management plans of multiple installations. At a minimum, the plan will include the following:

(1) An ACM inventory, conducted by sample and analysis or visual determination.

(2) A notification and education program to inform workers, tenants, and building occupants where potentially friable ACM is located, and how and why to avoid disturbing the ACM;

all persons affected should be properly informed.

(3) Regular ACM surveillance to note, assess, and document any changes in the ACM's condition.

(4) Work control/permit systems to control activities that might disturb ACM.

(5) Operations and maintenance (O&M) work practices to avoid or minimize fiber release during activities affecting ACM.

(6) Record-keeping to document O&M activities related to asbestos identification management and abatement.

(7) Training for the asbestos program manager, as well as custodial and maintenance staff.

(8) Procedures to assess and prioritize identified hazards for abatement.

(9) Procedures to prevent the use of ACM in new construction.

(10) Medical surveillance and respiratory protection programs required to support all USFK personnel involved in asbestos-related activities, IAW 29 CFR 1926.1101(h). Contractors are responsible for the health and safety of their personnel IAW applicable regulatory standards.

c. Prior to the demolition or renovation of a facility, the installation will make a determination whether or not the activity will remove or disturb ACM, and will record this determination on the project authorization document (e.g., work order).

d. Prior to the demolition or renovation of a facility that involves removing or disturbing friable ACM, a written assessment of the action will be prepared and furnished to the installation commander. A copy of the assessment will also be kept on permanent file.

e. Installations will remove friable ACM when the ACM poses a threat to release airborne asbestos fibers and cannot be reliably repaired or isolated.

f. Prior to disturbing or demolishing any part of a facility, all regulated ACM will be removed.

g. If in-house abatement is performed, installations will, as a minimum:

(1) Prior to removal, train all workers involved in the removal.

(2) Establish monitoring programs during asbestos removal operations to document exposure levels.

(3) Ensure that all workers involved in the removal use properly fitted respiratory protection and personal protection equipment.

(4) Use engineering controls and work practices to contain and control asbestos fiber releases for all asbestos removal that has the potential to release airborne asbestos fibers greater than the permissible exposure limit (PEL) of 0.1 fibers/cc.

h. Waste asbestos shall be collected and transported in double-layered, high-density, waterproof bags or air-tight containers after sufficient water has been sprayed to prevent scattering, and the cargo should be covered during transportation. In storage, waste asbestos shall be humidified and double wrapped with sacks, sealed in a sturdy container, or solidified with cement or synthetic polymer compounds, or by similar methods, so as not to be scattered during storage. Containers shall be labeled in both English and Korean as follows:

(1) Dust, debris, or materials that may easily be crushed by palm pressure shall be solidified or melted at high temperature.

(2) Solidified wastes considered to produce no airborne dust shall be packed in polyethylene or high density waterproof bags and disposed at a designated waste landfill.

(3) Vinyl sheets used for asbestos removal, protection masks, respirators, protection gear, etc. shall be packed in double-layered high density water-proof bags to be disposed at a designated wastes landfill, melted at high temperature, or solidified.

j. For demolition projects, all ACM will be removed prior to demolition. During the demolition process, if the ACM material is combined with the rest of the demolition debris, all of the mixed material will be managed and disposed of as ACM.

k. For renovation projects, all ACM will be removed from project debris and managed and disposed of as ACM. During the renovation process, if the removed ACM material is combined with the other debris, all of the nixed material will be managed and disposed of as ACM.

l. DoD schools will comply with applicable requirements 15 U.S.C. 2643(l) and implementing regulations in 40 CFR Part 763, Subpart E, ―Asbestos-Containing Materials in Schools.‖

m. Sampling of multi-layered interior wall systems:

(1) For multi-layered interior wall systems, including joint compound and skim coats, discrete layers from one sample location are combined to produce a composite analytical result. If the composite result is less than or equal to one percent, then the sampled material is not classified as ACM, and no further analysis is required. If the composite result is greater than one percent, then the sampled material is considered to be ACM.

(2) For multi-layered interior wall systems not including joint compound, the material is classified as ACM if asbestos content is greater than one percent. If no asbestos is detected in the composite sample, then the material is classified as non-ACM. However, if the analysis detects asbestos up to one percent, then each layer of the sample must be analyzed individually. If any one layer contains greater than one percent asbestos, then that layer is classified as ACM. If it is infeasible or impossible to separate the layers, then the entire sample is considered to be ACM.

As an alternative to the standard PLM method, and if available, composite samples may be gravimetrically analyzed to derive the percentage of asbestos by weight.

n. Exterior Textured Paint. ACM exterior textured paint is considered Category II non-friable ACM. For renovation projects, routine abatement and disposal procedures shall be followed when the impact of renovation activities may result in the release of significant levels of airborne asbestos fibers.

o. Training. All USFK personnel engaged in asbestos-related activities, including, but not limited to, the program manager, management planner, abatement project monitor, inspector, worker, project designer, supervisor, and operations and maintenance personnel, shall maintain US EPA AHERA accreditation commensurate with their asbestos-related duties and responsibilities. Completion of the appropriate class(es) and refresher training is required for USFK personnel maintaining accreditation. Contractors are responsible for the health, safety, and training of their personnel IAW applicable regulatory standards.

* 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

ABATEMENT DETAIL SHEETS

EP 1110-1-11

15 July 1992

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 HOUSACE/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 1-30) 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 61-1 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.
