MEMORANDUM

Subject: Asbestos Survey / Building A, 4th Floor

Date: February 9, 2023 Reply to Attention of: Daryl Kosturock, Environmental Manager

To: Henry Vo, Electrical Engineer

The GPO Safety Branch evaluated the spaces highlighted in the drawing seen below for the presence of asbestos containing materials (ACM) that may interfere with the construction / demolition tasks of converting this area of the building into Archival Storage for a tenant, the National Archives and Records Administration.

Scope: GPO Engineering has an upcoming project in design to move all GPO activities on the 4th Floor of Building A to another area in the complex, and convert this vacated space into Archival Storage for a tenant, the National Archives and Records Administration. A contractor or GPO Shops will perform major demolition and construction activities to accommodate this project.

Asbestos Survey Results: Asbestos was widely used in building materials prior to 1980.

Since the GPO Central Complex buildings were constructed before this time, ACM can be found in building materials such as pipe insulation, troweled-on plaster, fire doors, wallboards, roof chalking and sealants, and vinyl floor tiles. Though much of the Building’s ACM has been removed, some of these building materials are still present. Provided that the materials remain intact and undisturbed, the materials do not present an exposure risk. There are several areas of known ACM scattered throughout the footprint of this project and are noted below.

Known ACM: *Note: the following pictures will show several pipes wrapped with insulation.

Generally, the Thermal Systems Insulation (TSI) with ACM will have Yellow and Black Caution stickers affixed, while the other unlabeled pipes are wrapped with TSI containing fiberglass.

1) Stairway 4: Vertical chilled water pipes wrapped in TSI containing ACM, with branch pipes feeding the 4th Floor that are also wrapped in TSI with ACM.

2) Column 4C13: Chilled water pipes wrapped in TSI with ACM.

3) A424A, East wall: Chilled water pipes wrapped in TSI with ACM.

4) Column 4F8: Chilled water pipes wrapped in TSI with ACM.

5) Column 4F7: Hot water pipes wrapped in TSI with ACM.

6) Columns 4A4 / 4A5: Rain leader pipes wrapped in insulation with ACM.

7) A424 / A424A / A425: Asbestos-containing, cement-board material (Transite) secured to the metal cage and used as wall boards:

8) Shafts: Several of the shafts in the GPO Central Complex are known to contain ACM, mostly TSI and some cementious material. A visual inspection of the shafts on the 4th Floor revealed no obvious ACM present. However, if any of these shafts must be entered from different floors in support of this project, ACM may be present.

Questionable Building Materials: Materials were found that required laboratory analysis to determine the presence of ACM. As seen in ATTACHMENT A, there was no ACM detected.

1) Entire 4th Floor: 12” X 12” fibrous (acoustic) ceiling tiles. *Note: the area survey revealed all ceiling tiles appeared to be fastened with nails and no mastic was found. There are other known areas within the Central Complex where mastic was used to fasten similar tiles. Laboratory results of that mastic have revealed both non-detect and ACM present.

Recommendations: All work may proceed since all known ACM appears to be in good condition and questionable materials were determined to not contain ACM. Additionally;

1) Proper safe work practices and procedures shall be used while performing tasks in support of this project to minimize contact with ACM.

2) Care shall be used while entering all shafts within the Central Complex.

3) If previously unknown questionable materials are discovered during the demolition phase, samples shall be sent to a NVLAP Accredited laboratory to determine the presence of ACM, prior to disturbing these materials.

4) All known and unknown ACM that may interfere with this project shall be removed by a qualified ACM removal company, licensed through the District of Columbia, per 20 DCMR, Section 800 “Control of Asbestos.”

Subject: NARA 4th Floor Archive Storage Lead Survey Date: November 8, 2022 Reply to Attention of: Joselito Sto Tomas, Industrial Hygienist, Safety Branch To: Henry H. Vo, Electrical Engineer, Facilities Management Office

1. On 10/4-10/24/22, the IH conducted a lead survey of the Bindery area. The Bindery area is located on Bldg. A 4th Floor. The survey was requested by the Electrical Engineer to determine what architectural components in the Bindery area contain lead based or lead containing paint that would be impacted during the planned renovation of Bldg. A, 4th Floor.

The IH used a Niton XLp 301A Lead Paint analyzer to conduct non-destructive, real time testing of painted architectural components. 1.0 mg/cm2 is the Department of Housing and Urban Development (HUD) testing standard for lead based paints. Any result at or above the standard means that the architectural component tested has lead-based paint and will show as positive result. Any result below the standard has lead levels below 1.0 mg/cm2 and will would show as a negative result. Note that a negative result does not mean that the surface has no lead content.

2. The results of the testing are as follows:

3. Observations:

a) The IH was not able to access the ceiling of the 4th floor, Bldg. A. Kindly notify the IH if the ceiling will be impacted so that XRF testing can be done.

b) The pipes have typically 2 surfaces. The lower half has a metal guard while the upper part has a pipe wrap surface. Both surfaces tested negative for lead based paint.

c) It is noted that the top half of the walls and columns have generally tested to be positive for lead based paint.

d) Footer refers to the architectural component found at the base of safety railings, walls and columns

e) It should be stressed that a negative reading by the Niton XRF paint analyzer does not mean that there is no lead present in the paint/coatings used. It means that the lead present in the paint coating does not reach the HUD standard for lead based paint. Lead containing dust will be generated when the architectural components are impacted during the decommissioning activities of the presses.

4. Recommendations:

a. It is recommended that workers use proper work practices and procedures. The level of protection must be commensurate with the method being used. Half and full-face respirators will require a fit test and medical examination.

5. A spreadsheet containing the XRF readings will be attached to this report. If you have any questions, please contact me at extension 2-1477.
