HAZARDOUS MATERIALS SURVEYSBuilding 32/42 AHU Replacement

University of the District of Columbia4200 Connecticut Avenue NW

Washington, DC 20008

Purpose and Scope of Service

The purpose of this project was to conduct limited hazardous materials surveys inaccessible portions of Buildings 32 and 42 of the University of the District of Columbia,Van Ness Campus, Washington, DC, identified by Alphatec PC as locations potentiallyimpacted by the planned renovation project. The testing was performed in accordancewith the following scope of work:

Asbestos-Containing Materials

(1) Licensed asbestos inspectors conducted a survey of accessible building materialssuspected to contain asbestos that are anticipated to be impacted by the plannedAHU Replacement project. The survey was conducted in accordance withOccupational Safety and Health Administration (OSHA) requirements andEnvironmental Protection Agency (EPA) AHERA guidelines for the locations andnumber of samples to be collected. The survey included a visual inspection ofbuilding materials, a review of construction documents and any previous reportsas made available by the Client or on-site personnel, and sampling and analysisof suspect materials to identify the presence of asbestos.

(2) AERO temporarily repaired interior areas from which friable samples werecollected by using a filler compound, spraying with an acrylic clear paint, or bycovering with duct tape where appropriate. Interior non-friable sample locationswere not repaired.

(3) AERO did not sample roofing materials as part of this project.(4) AERO collected bulk samples from each homogeneous area in accordance with

OSHA and EPA guidelines. Three samples of thermal system insulation, three toseven samples of surfacing material, and at least one sample of eachmiscellaneous material are required. The inspectors may have, at their discretion,collected more than one sample of each suspect miscellaneous material.

(5) The samples were analyzed for asbestos fiber content at a laboratory accreditedunder the National Voluntary Laboratory Accreditation Program using polarizedlight microscopy (PLM) in accordance with EPA Methods 600/M4-82-020 and/or600/R-93/116.

(6) Based upon the analytical results and review of drawings and blueprints madeavailable by the Client or on-site personnel, the approximate amounts, types,

Page 2 of 8Alphatec PC. UDC Building 32/42 AHU Replacement

Washington, DC

locations, and conditions of accessible ACM were determined. AERO reported onany ACM that is suspected of penetrating into inaccessible areas.

Lead-In-Paint Screening

(7) A licensed District of Columbia/EPA Lead Risk Assessor trained in samplingprotocols and use of the NITON XLp-300AW X-Ray Fluorescence Analyzer (XRF)conducted representative testing of painted surfaces within the building.

(8) Use of the XRF instrument was in general accordance with the PerformanceCharacteristic Sheet (PCS) methodology for the NITON XLp-300 dated September24, 2004. XRF instrument calibration checks were performed according to thePCS. The PCS is provided as supplemental guidance to the US Housing andUrban Development (HUD) “Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing” and is a joint product of HUD and EPA.

(9) Testing locations were identified by substrate type, component, and color.Surfaces tested only included painted building components that will be impactedby the renovation.

PCB Light Ballasts

(1) AERO conducted a visual survey of accessible representative light fixtures forPCB-containing light ballasts in accordance with generally accepted industrypractices and EPA guidelines.

(2) Light ballasts were inspected for “No PCBs” markings. Ballasts that were free ofmarkings or missing labels were assumed to contain PCBs.

Mercury-Containing Switches and Fixtures

(1) AERO conducted a visual survey for accessible mercury-containing switches andfixtures in accordance with generally accepted industry practices and EPAguidelines. The survey included a visual inspection of representative switches.

(2) All fluorescent light tubes were assumed to contain mercury.

Other Hazardous Materials

(1) AERO inspected the Site for chemical storage, non-ballast sources of PCBs, andequipment that may contain Freon®. Evidence of other sources of PCBs includes,but is not necessarily limited to, transformers, capacitors, and hydraulicallyoperated equipment. Evidence of sources of Freon® includes, but is notnecessarily limited to, refrigeration and cooling equipment.

Asbestos-Containing Materials Survey

The following is a list of suspect asbestos-containing materials identified during the walk-through inspection conducted on September 26, 2017:

White Mastic on Metal HVAC Duct Seams Off-White Mastic on Metal HVAC Duct Seams Drywall and Associated Joint Compound White Mastic on Foil-Faced Fiberglass Duct Insulation 2’ x 5’ Ceiling Tiles

o Random Nickso Pock Marks

Grey Mastic on Metal Duct Seams White Mastic on Fiberglass Pipe Insulation Tan Mastic on Metal Ducts 2’ x 2’ Ceiling Tile

o Smooth, Vinyl Clado Recessed

Spray-Applied Fireproofing Cloth Flex Joints on HVAC Units Red Mastic on Metal Duct Seams Lab Hoods, Interior Panels (ASSUMED)

AERO collected thirty-four (34) bulk samples of suspect asbestos-containing materials,resulting in thirty-four (34) analyses. The samples were analyzed by Scientific AnalyticalInstitute, Inc. (SAI) using polarized light microscopy (PLM) according to EPA Method600/R-93/116. SAI participates in the National Voluntary Laboratory AccreditationProgram (NVLAP Lab Code 200664-0) and is accredited by the National Institute ofStandards and Technology (NIST).

Laboratory analysis indicated the following materials contained asbestos:

* The extent to which these materials will be impacted by the scope of the renovationproject was not known at the time of the survey. The quantities presented in this tableare estimates for materials observed in the locations where the samples werecollected.

The bulk sample log and analytical report in Appendix A contain a listing of analyzedsamples, sample locations, and analytical results for the samples collected at this facility.Results are reported in percent asbestos by volume and indicate the type(s) of asbestos.Common non-asbestos components may also be noted in the analytical report. Adiagram depicting the sample locations is included in Appendix B.

Discussion – Drywall Systems and Point Count Analysis

EPA regulations state “if the asbestos content is less than 10 percent as determined bya method other than point counting by polarized light microscopy (PLM), verify theasbestos content by pointing using PLM”. If point counting is not performed as specifiedby the EPA, then the material is assumed to contain greater than 1% asbestos. Inpractical application, the need to conduct point count analyses only arises when asbestosis likely to be present in concentrations of 1% or less.

One of the few areas where EPA and OSHA regulations differ significantly is in thehandling and disposition of drywall systems consisting of drywall and joint compound.

Page 5 of 8Alphatec PC. UDC Building 32/42 AHU Replacement

Washington, DC

The EPA considers drywall systems consisting of both drywall and joint compound to bea single entity, whereas OSHA considers drywall and joint compound to be two separatematerials.

When asbestos is present in drywall systems, typically it will only be present in the jointcompound at concentrations less than 5% and not in the drywall itself. Drywall systemsseldom have asbestos concentrations greater than 1% since the drywall-to-jointcompound weight-to-weight ratio is normally in excess of 10:1.

The EPA does not regulate the removal and disposal of drywall systems if the combinedasbestos concentration of the drywall/wall joint compound system (a composited sampleof both materials) is determined to be one percent asbestos or less when analyzed usingEPA point count analysis procedures. OSHA still regulates the material if the asbestosconcentration in the joint compound via point count is in excess of 1%.

One of the samples of drywall and joint compound collected by AERO in MechanicalRoom 32 contained 2% asbestos in the joint compound layer.

Lead-in-Paint Screening

The following building components identified during the walk-through inspection weresuspected of being coated with paint containing lead:

Metal Fan Supports Metal Fan Motors Metal Cooling Tower Concrete Grey Floors Metal Ductwork (Exterior) Foam Roofing Drywall Walls Metal Fume Hoods Concrete Walls Metal Air Handling Units (AHU) Metal AHU Supports Metal Ductwork (Interior) Concrete Wall Blocks Metal Fume Hoods, Black

XRF testing revealed the following surface had a lead concentrations of 1.0 mg/cm2 orgreater.

Metal Fume Hoods, Black

The following surfaces had lead concentrations less than 1.0 mg/cm2, but greater thanthe limit of detection for the instrument used:

Metal Ductwork (Exterior) Metal Fan Motors Drywall Walls Metal Air Handling Units (AHU) Metal AHU Supports Metal Ductwork (Interior) Concrete Wall Blocks Metal Fume Hoods, Blue

Page 6 of 8Alphatec PC. UDC Building 32/42 AHU Replacement

Washington, DC

XRF testing revealed lead concentrations less than the limit of detection for the instrumentused on the remaining surfaces. The XRF testing results are included in Appendix C. Adiagram depicting the XRF reading locations is included in Appendix D.

Current District of Columbia regulations define a lead-based paint as any paint or othersurface coating containing lead or lead in its compounds in any quantity exceeding onehalf percent (0.5%) of the total weight of the material or more than one milligram persquare centimeter (1.0 mg/cm2), or such more stringent standards as may be specified inFederal law or regulations promulgated by EPA or the United States Department ofHousing and Urban Development (HUD), which shall be adopted by the Mayor by rule.

The OSHA Standard requires an employer to ensure that no employee is exposed to leadat concentrations greater than 50 micrograms of lead per cubic meter of air (µg/M3)averaged over an eight-hour period. The standard further requires the employer to makea determination of its employees' potential exposure to lead. The standard detailspresumed exposure levels for various construction activities. The employer must provideadequate personal and respiratory protection to match the presumed exposure listed inthe standard. Deviation from the presumed exposure is typically achieved by performingpersonal monitoring during various representative construction activities. The level ofpersonal and respiratory protection can then be modified based upon the results of themonitoring.

Environmental Protection Agency (EPA) regulations concerning lead hazardous wasterequire the collection of representative samples of the demolition waste stream. Thesesamples must be analyzed using EPA’s Toxicity Characteristic Leaching Procedure(TCLP). If TCLP analysis reveals a leachate concentration of 5 parts per million of leador higher, the waste stream must be treated as hazardous waste and handledaccordingly.

PCB Light Ballast Survey

AERO inspected representative light fixtures within the building for suspect PCB ballasts.Metal casings covering the ballasts within the fixtures were removed, and the labels ofthe ballasts were inspected for “No-PCB” markings.

Representative light fixtures that were inspected were labelled with “No PCB”identification markings; therefore, these ballasts can be assumed not to contain PCBs.

Washington, DC

Mercury-Containing Switches and Fixtures Survey

AERO visually inspected representative light fixtures for suspect mercury-containingfluorescent light tubes. AERO identified suspect mercury-containing light tubes but didnot quantify them as the light tubes are not expected to be discarded as part of thisproject.

Other Hazardous Materials

Freon®-containing equipment

AERO observed the following suspect Freon®-containing equipment:

Water fountains (assumed locally cooled by refrigeration unit)

Chemicals and Chemical Storage

Storage areas and classrooms in the project areas were observed to contain chemicalsand other potentially hazardous products. These materials included, but are not limitedto, various laboratory chemicals in chemistry labs, commercial cleaning products, andother office supplies.

Conclusions and Recommendations

The following conclusions and recommendations are based upon the work conducted forthese surveys and AERO’s understanding of the project.

A. The EPA classifies non-friable white mastic associated with the foil-facedfiberglass duct insulation, white mastic associated with fiberglass pipe insulation,the various mastics on metal duct seams (tan, red, grey), joint compoundassociated with the drywall walls, and the assumed asbestos-cement panelsassociated with the lab hoods as Category II non-friable materials. Materialsidentified in this report as asbestos-containing should be abated and disposed ofprior to scheduled renovations that would result in their disturbance. A licensedasbestos abatement contractor should perform the removals.

B. Lead-based and lead-containing paints were identified during the survey. Removalof paint with lead as a result of renovation activities does not necessarily constitutea lead paint abatement provided the lead paint(s) have not been included in therenovation plans to reduce or eliminate a lead hazard. However, if lead paint isremoved with the intention of reducing or eliminating a lead hazard, then theremoval must be performed by a licensed lead abatement contractor.

Page 8 of 8Alphatec PC. UDC Building 32/42 AHU Replacement

Washington, DC

C. Painted surfaces containing lead in any concentration must be handled inaccordance with 29 CFR 1926.62, the OSHA Lead Exposure in ConstructionStandard. Therefore, contractors should be notified of all known lead-containingpaints prior to bidding on work at the Site.

D. Representative demolition waste stream samples should be collected andsubmitted for TCLP analysis. Should TCLP results reveal lead concentrations of5 parts per million or higher, the waste stream should be handled and disposed ofas hazardous waste.

E. The inspection of representative fixture ballasts during the survey determined thatthe ballasts were marked with the “No PCB” identification markings. All lightfixtures should be inspected at the time of removal for “No-PCBs” markings on theballast labels prior to their disposal.

If light ballasts are encountered during the renovations that do not have a “noPCBs” marking on the label, the light ballasts should be removed and disposed ofin accordance with EPA requirements in TSCA and RCRA as well as applicablestate and local regulations.

F. Fluorescent light tubes potentially contain mercury vapor and should be removedintact from the Site prior to renovation activities that may disturb them. Thesetubes are not expected to be replaced as part of the anticipated renovation project.Fluorescent light tubes should be handled and disposed/recycled as a universalwaste in accordance with EPA RCRA requirements as well as applicable state andlocal regulations.

G. All refrigerants should be removed (recycled) from all non-portable equipment andall portable equipment slated for disposal prior to renovation of the structure.Freon® or other refrigerants should be properly reclaimed from the equipment bya licensed HVAC contractor and recycled by a licensed recycler according toFederal, state, and local regulations prior to renovation of the structure.

H. Various chemicals were observed in locations throughout the building. Anychemicals and products which still have a use should be removed from the buildingprior to renovation of the structure. If any of these products remain, they willrequire collection, waste characterization, and proper disposal prior to anyrenovation activities.
