WORK ITEM 3: Perform ACM Condition Assessment

1. SCOPE

1.1 Intent. This work item describes the requirements for the Contractor to perform an ACM condition assessment, as designated in the Task Order.

NOTE

Purpose of assessment is to identify and quantify damage to existing vermiculite

ACM

coatings and determine the potential for disturbance and potential exposure risks for crew personnel during operations and space access.

Location of assessment designed in the

Task Order may be as follows:

overhead, bulkhead, and bilge surfaces;

electrical cable and pipe runs.

1.2 Government-furnished Property. None.

3. REQUIREMENTS

3.1 General.

3.1.1 CIR. None.

3.1.2 Tech Rep. Not applicable.

3.1.3 Protective measures - general. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces in the vicinity of the work area against contamination during the performance of work. Upon completion of work, the Contractor shall remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness.

3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences).

3.1.5 Location identification. As part of testing and identification process for ACM, ensure that deck numbers, compartment names and frame numbers are used to document locations where each sample has been taken. Be aware that the frames are the ribs of the ship and serve as vertical boundaries for compartments. Compartment numbers consist of four parts, separated by hyphens, in the following sequence (example: 2-20-3-L):

1) Deck number

2) Frame number

3) Position relative to ship centerline

4) Use of Compartment

3.1.6 Report submissions. Expedite shipment and analysis of all sample results for receipt within 5 business days. Provide detailed written report of findings to include at a minimum:

· Company performing assessment

· Coast Guard Cutter being assessed

· Location of samples taken (3.1.5)

· Results of laboratory testing of bulk samples.

· Type of laboratory testing completed.

· Square footage of any failures.

· Potential health risks to crew.

· Recommendation for further actions to be taken.

Report may be submitted as part of or addition to other reports as necessary.

3.2 Condition assessment. The Contractor shall accomplish the following tasks:

3.2.1 Identification of homogenous areas. Identify and document homogenous areas (see 4.1.1 (Homogenous areas) – for use as the basis for condition assessments and bulk sample collection. Ensure that the homogenous areas (i.e. vermiculite coating) are identified during initial evaluations and their locations are indicated for each designated vessel being assessed.

NOTE

Identification of homogenous areas may at times be difficult because the

ACM

can be covered by many layers of paint.

3.2.2 Assessment framework. Conduct assessments frame to frame and assessed from centerline to port bulkhead and then centerline to starboard bulkhead, to include all areas, as follows:

3.2.2.1 Coating failures:

3.2.2.1.1 Identify all areas where damage and deterioration may be illustrated by:

· Delamination: separation of ACM from the substrate, separation of the ACM into layers and coated surfaces that give slightly, when hand pressure is applied.

· Flaking, blistering, cracking, crumbling, scrapes, gouges, or other physical damage.

· ACM coating debris observed on horizontal surfaces.

· Water damage, significant or repeated water stains.

3.2.2.1.2 Ensure that all coating failures, damages and deteriorations are identified and classified into two categories:

· Current failure: all coatings that currently have damage and/or deterioration as described previously. This category shall capture all coatings with the potential to release asbestos fibers

· Previous failure: all areas where coatings have previously failed, often indicated by intermittent smooth surfaces in otherwise ACM coated areas, but have been subsequently coated with fresh paint in an attempt to stabilize. These areas do no currently have damage or the potential to release asbestos fibers.

3.2.2.2 Potential for disturbance: Ensure that all areas with potential for disturbance are also evaluated when conducting condition assessments.

NOTE

Evaluation for potential for disturbance includes the potential for future damage, disturbance or erosion of material, accessibility of the material, frequency that the area is used, and activates likely to cause damage.

Therefore, all damage and/or deteriorated

ACM

coatings and ACM coated substrates subject to constant vibration, extreme temperature variations, air erosion, physical contact, or located in work areas are considered high potential for disturbance.

3.2.3 Friability test. Physically test vermiculite coating for friability in one-third of each homogenous area. Target heavily damaged areas, which will provide the best access to the vermiculite coating located on the substrate without interference from the layers of paint.

3.2.4 Damage estimation: Estimate the total surface area of current failures, to include both the damaged area and surrounding coatings to six inches beyond a projected intact coating edge. The estimates shall be recorded in square feet and used to calculate a percentage of deteriorated coating using the previously calculated total surface area for each identified homogenous area as indicated by the equation below. Final estimates shall include a margin of error of +/- 10% and shall be presented as a range.

3.2.5 Location identification. During the assessment, deck numbers, compartment names and frame numbers shall be used to document locations of damaged ACM. Be aware that the frames are the ribs of the ship and serve as vertical boundaries for compartments. Compartment numbers consist of four parts, separated by hyphens, in the following sequence (example: 2-20-3-L):

1) Deck number

2) Frame number

3) Position relative to ship centerline

4) Use of compartment

4. TESTING

Take samples of identified failing homogenous areas to submit for laboratory testing to identify the presence of asbestos, not to exceed 10 samples.

Any material containing more than one percent (1%) asbestos as determined using the methods specified in AHERA 40 CFR Part 763, Section 1, Subpart F, Appendix A. The percentage of asbestos in a material can only be determined by laboratory analysis. A homogenous area will be categorically classified as asbestos-containing material when bulk samples reveal more than one percent (1%) asbestos by laboratory analysis.

5. NOTES

5.1 Term definitions.

Homogenous area. A homogeneous area is defined as an area of ACM surfacingmaterial, thermal system insulation material, or miscellaneous material that is uniformin color and texture. Teams will define the homogenous areas (i.e. vermiculite coating) during their initial evaluations and indicate the locations of each on the tender and barge diagrams in A homogeneous area is defined as an area of ACM surfacing material, thermal system insulation material, or miscellaneous material that is uniform in color and texture.

Friability. Friable ACM is defined as any material containing more than one percent(1%)asbestos, which when dry, can be crumbled, pulverized or reduced to powder by hand pressure. The vermiculite asbestos-containing coatings found onboard tenders and barges have been covered by multiple layers of paint over the years. Bulk samples o fthese coatings were previously tested for friability and were deemed friable. However,friability is dependent on several factors and can vary somewhat even within a single homogenous area. Therefore, assessment teams will physically test vermiculite coating for friability in one-third of their sampling locations per homogenous area. Assessors should target heavily damaged areas, which will provide the best access to the vermiculite coating located on the substrate without interference from the layers of paint.

ACM evaluation criteria. Any material containing more than one percent (1%) asbestos as determined using the methods specified in AHERA 40 CFR Part 763, Section 1, Subpart F, Appendix A. The percentage of asbestos in a material can only be determined by laboratory analysis. A homogenous area will be categorically classified as asbestos-containing material when bulk samples reveal more than one percent (1%) asbestos by laboratory analysis.
