END OF SECTION 024119

July 28, 2017 City of Richmond Special Capital Projects 900 East Broad Street Room 602 Richmond, Virginia 23219 ATTN: Mr. Gregory “Lacy” Salomone Capital Projects Manager Special Capital Projects Group RE: Asbestos & Lead-Based Paint Inspection Report City Hall Roof - Cooling Tower Replacement Project 900 East Broad Street Richmond, Virginia 23219 FEI Project Number: FEI17AL389 Dear Mr. Salomone: France Environmental, Inc. (FEI) has completed the asbestos and lead-based paint (LBP) sampling of suspect building materials in the building referenced above. FEI’s scope of work consisted of a limited survey of the roof cooling tower enclosure and cooling tower platform. Mr. Micheal D. Allshouse (Virginia Asbestos Inspector License Number 3303003902 and Virginia Lead Inspector/Risk Assessor License Number 3356001040) conducted the fieldwork on July 18, 2017. Asbestos Sampling: FEI collected Fourteen (14) bulk samples of suspect asbestos-containing building materials (ACBM’s). A list of the samples collected and the results of these samples can be found in the attached Bulk Sample Summary Sheet. FEI hand delivered the samples to AmeriSci Richmond. Located in Midlothian, Virginia where they were analyzed for the presence of asbestos. A material is considered by the EPA and the Commonwealth of Virginia to be asbestos-containing if at least one (1) sample collected from a multi-sample group contains asbestos in an amount greater than one percent (>1%). The following building materials sampled were determined to be asbestos–containing:

White Pipe Insulation Mastic, South Filter Room If a building material results in a trace of asbestos (≤1%), this material is not considered an asbestos-containing building material (ACBM) according to EPA’s definition. However, additional worker protection, air monitoring, worker general awareness training and disposal methods may be required during any renovation or demolition activities that involve the disturbance of these materials in accordance with the Occupational Safety and Health Administration (OSHA)

COR City Hall Roof Cooling Tower Replacement Richmond, VA (Asbestos/Lead Sampling) Page 2 FEI Project Number: FEI-17AL389 7/28/2017

Guidelines. The removal/demolition of a material containing one percent or less of asbestos is considered “Unclassified Asbestos Work” provided the Permissible Exposure Levels (PEL’s) are not exceeded. This means that only certain Work Practice Standard's, Engineering Control Obligations, and Prohibitions pertain including, but may not be limited to, the ones defined in the OSHA Guidelines under 29 CFR 1926.1101 and clarified in the August 13, 1999 OSHA letter regarding the Requirements for demolition operations involving material containing (≤1%) asbestos. Asbestos NESHAP requires that each owner or operator of a demolition or renovation activity involving Regulated Asbestos Containing Material (RACM) remove all such material from a facility being demolished or renovated before any activity begins that would break up, dislodge, or similarly disturb the material or preclude access to the material for subsequent removal. Building materials containing one percent or less (≤1%) of asbestos may be removed prior to demolition or included with the building demolition provided regulations are followed as described in the paragraph above. ACM need not be removed before demolition if it: (i) Is a Category I non-friable ACM that is not friable. (ii) Is on a facility component that is encased in concrete or other similarly hard material and is

adequately wet whenever exposed during demolition. (iii) Was not accessible for testing and therefore was not discovered until after demolition

began and, as a result of the demolition, cannot be safely removed. If not removed for safety reasons, the exposed RACM and any asbestos-contaminated debris must be treated as asbestos-containing waste material and kept adequately wet at all times until disposed of.

(iv) Is a Category II non-friable ACM and the probability is low that the material will become crumbled, pulverized, or reduced to powder during demolition.

A complete summary of the materials sampled and the location of these materials can be found in the Sampled Material Data Summary Charts. Copies of the laboratory report, sample location “field sketch” drawings, and the inspector’s license have also been attached to this report. Lead-Based Paint Sampling: The lead-based paint (LBP) survey was performed by an EPA accredited and Virginia licensed lead-based paint inspector. An X-Ray Fluorescence (XRF) machine is a portable, non-destructive testing device, which was used to measure the lead content in paint. XRF field-testing was performed with the LPA-1, manufactured by Radiation Monitoring Devices (RMD). XRF test data, including calibration checks against known standards, were recorded on inspection worksheet(s) to generate a permanent record of the data. During the lead inspection, FEI may not conduct lead testing in every room and/or sample every painted/varnished/stained building component. However, all like building materials, i.e., same color/substrate, etc., are grouped together and considered positive or negative in conjunction with the building materials that were sampled. FEI conducts sampling of building materials that are representative of the possible lead containing materials in a building. Seven (7) shots were taken with the XRF machine to determine the lead content of the building components. A list of lead painted building components that tested above the level set by the

COR City Hall Roof Cooling Tower Replacement Richmond, VA (Asbestos/Lead Sampling) Page 3 FEI Project Number: FEI-17AL389 7/28/2017

Commonwealth of Virginia for XRF testing for paint to be considered lead paint (≥1.0 mg/cm2) is as follows:
