ASBESTOS SURVEY REPORTLAKESIDE PLANT AND SALUDA 1, 2, 3, & 4 PUMP STATIONS

GREENVILLE, SOUTH CAROLINATerracon Project No. 86157107

1.0 INTRODUCTION

Terracon Consultants Inc. (Terracon) conducted asbestos surveys at the Renewable WaterResources (ReWa) Lakeside Plant and four wastewater pump stations (designated Saluda 1through Saluda 4). These sites are generally located adjacent to the Saluda River in Greenville,South Carolina (see Figure 1). Our survey was conducted on November 13, 2015 in support ofplanned selective demolition efforts and was performed in general accordance with the terms ofour Proposal Number P86150350, dated October 30, 2015. EPA regulation 40 CFR 61, SubpartM, National Emission Standards for Hazardous Air Pollutants (NESHAP), prohibits the release ofasbestos fibers to the atmosphere during renovation/demolition activities. NESHAP requires thatpotentially regulated asbestos-containing materials (ACM) be identified, classified and quantifiedprior to planned disturbances or demolition activities.

The asbestos surveys were conducted by South Carolina Department of Health andEnvironmental Control (SC DHEC) licensed building inspectors. Building components weresurveyed and homogeneous areas of suspect ACM were visually identified and documented, ifpresent. Although reasonable effort was made to survey and locate accessible suspect materials,additional suspect but un-sampled materials could be located in walls, in voids or in otherconcealed areas.

2.0 BUILDING DESCRIPTIONS

Only selected structures located at the Lakeside Plant were surveyed. Those structures consistedof a circular clarifier, an adjacent pump vault, and an aboveground caustic dosing tank andassociated pump and piping. The clarifier is constructed of concrete walls, a concrete floor, andwith associated metal piping, stairs and other components. The adjacent pump vault isconstructed of concrete with a metal lid. The caustic dosing tank is located on a concrete padwith concrete walls. Piping was observed to be uninsulated or insulated with Styrofoam that iscovered with metal jacketing. Gaskets were observed to be rubber. Other structures located atthe Lakeside plant were not surveyed as they are not slated for demolition.

Saluda 1, 2, 3, and 4 pump stations are each approximately 120 square feet and constructed ofconcrete block on a concrete pad. Saluda 1 has applied material to the exterior walls. The interiorwall finishes of all pump stations are painted concrete block. Each pump station has a sub-gradelevel that is approximately 10 feet below ground surface. Saluda 2, 3, and 4 have built-up roofingmaterials over a concrete deck while Saluda 1 has a rounded concrete roof covered with asuspect coating.

3.0 ASBESTOS SURVEY

The asbestos surveys were conducted by Messrs. Eli Webster and Stephen Ellis, both SCDHEClicensed Asbestos Building Inspectors (License Nos. BI-01382 & BI-01211, respectively). Copiesof these gentlemen’s licenses are provided in Appendix D. The surveys were conducted onNovember 13, 2015, in general accordance with the sampling protocols established by EPARegulation 40 CFR 763 (AHERA) and SCDHEC R61-86.1. A summary of survey activities isprovided below.

3.1 Regulatory Overview

An ACM is defined as any material containing asbestos of any type in an amount greater than onepercent (1%). The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiberemissions and asbestos waste disposal practices. It also requires the identification andclassification of existing building materials prior to demolition or renovation activity. UnderNESHAP, asbestos-containing building materials are classified as either friable, Category I non-friable or Category II non-friable ACM. Friable materials are those that, when dry, may becrumbled, pulverized or reduced to powder by hand pressure. Category I non friable ACMincludes packing materials, gaskets, resilient floor coverings and asphalt roofing productscontaining more than 1 percent (%) asbestos. Category II non-friable ACM are non-friablematerials other than Category I materials that contain more than 1% asbestos.

Friable ACM, Category I and Category II non-friable ACM which is in poor condition and hasbecome friable or which will be subjected to drilling, sanding, grinding, cutting or abrading andwhich could be crushed or pulverized during anticipated renovation/demolition activities areconsidered regulated ACM (RACM). RACM must be removed prior to renovation or demolitionactivities.

In the state of South Carolina, asbestos activities are regulated by the SCDHEC under theSCDHEC Regulation 61-86.1 Standards of Performance for Asbestos Projects. The SCDHECrequire that any asbestos-related activity conducted in a public building be performed bypersonnel licensed by the SCDHEC. The owner or operator must provide the SCDHEC withwritten notification of planned abatement and removal activities prior to the commencement ofthose activities. The SCDHEC requires a four (4) day notification for non-friable projects and 10day notification for RACM projects. Asbestos abatement must be performed by SCDHEC-licensed asbestos abatement contractors. A SCDHEC-licensed Project Designer shall prepare awritten abatement design for each abatement renovation project involving the removal of greaterthan 3,000 square, 1,500 linear, or 656 cubic feet of RACM. Third-party air monitoring must beconducted during the abatement of friable (regulated) ACM. The SCDHEC asbestos regulationscan be found at http://www.scdhec.gov/environment/baq/Asbestos/asbestos_regulations.asp.

The Occupational Safety and Health Administration (OSHA) Asbestos Standard for ConstructionIndustry (29 CFR 1926.1101) regulates workplace exposure to asbestos. The OSHA standardrequires that employee exposure to airborne asbestos fibers be maintained below 0.1 asbestosfibers per cubic centimeter of air (0.1 f/cc). The OSHA standard classifies construction andmaintenance activities, which could disturb ACM, and specifies work practices and precautionswhich employers must follow when engaging in each class of regulated work. A full copy of theOSHA asbestos standard for general industry may be found at OSHA’s website (www.osha.gov)and should be referenced for specific information.

3.2 Visual Assessment

Our survey activities began with visual observation of the interior and exterior of the structures toidentify apparent homogeneous areas of suspect ACM. A homogeneous area consists of buildingmaterials, which appear similar throughout in terms of color, texture and date of application.Building materials which were not identified as concrete, glass, wood, masonry, metal or rubberwere considered suspect ACM.

3.3 Physical Assessment

A physical assessment of each homogeneous area of suspect ACM was conducted to assess thefriability and condition of the materials. A friable material is defined by the EPA as a material,which can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friabilitywas assessed by physically touching suspect materials.

3.4 Sample Collection

Based on the results of the visual sampling, bulk samples of suspect ACM were collected ingeneral accordance with sample collection protocols as required by SCDHEC Regulation 61.86.1.Random samples of suspect materials were collected in each homogeneous area. Bulk sampleswere collected using wet methods as applicable to reduce the potential for fiber release. Sampleswere placed in sealable containers and labeled with unique sample numbers using an indeliblemarker.

3.5 Sample Analysis

Bulk samples were submitted using chain-of-custody procedures to Scientific Analytical Institute(SAI) of Greensboro, North Carolina. SAI is accredited under the National Voluntary LaboratoryAccreditation Program NVLAP (#200644-0). The samples were submitted for a “positive stop”analysis which means once a sample is detected with asbestos; the remainder samples in thehomogenous set is not analyzed and are presumed to be of similar asbestos content.

Asbestos analysis was performed by PLM with dispersion staining techniques per EPAEPA/600/R-93/116. The percentage of asbestos, where applicable, was determined bymicroscopical visual estimation. Per the SCDHEC Regulation 61-86.1 Standards of Performancefor Asbestos Projects, negative results for non-friable organically bound (NOB) materials such asflooring, mastics, or roofing shall be verified with at least one TEM analysis. The additionalanalysis was performed by TEM in accordance with EPA/600/R-93/116 Section 2.5.5.1.

3.6 Findings and Recommendations

A total of sixty-two (62) bulk samples were collected from the structures. A map indicating thegeneral locations of the five sites is presented in Figure 1 in Appendix A. General layouts of thestructures with sample locations are included as Figures 2 through 6 (Appendix A). Sampledescriptions, locations, analytical results, classification, and estimated quantities are summarizedin Table 1 in Appendix B. Copies of asbestos laboratory analytical reports are included inAppendix C and photographs are provided in Appendix E.

Asbestos was identified in samples of the following materials:

Lakeside PlantNo asbestos detected

Saluda 1 Pump Station§ Exterior coating with black mastic (2% chrysotile)§ Exterior coating with webbing (2% chrysotile)§ Exterior coating (3% chrysotile)

Saluda 2 Pump Station§ Roof flashing (10% chrysotile)

Saluda 3 Pump StationNo asbestos detected

Saluda 4 Pump StationNo asbestos detected

Saluda 5 Pump StationNo asbestos detected

Asbestos-containing materials should be removed by a South Carolina licensed asbestosabatement contractor prior to beginning demolition. Depending on the method of abatementselected for the asbestos-containing coatings present on the exterior of the Saluda 1 pumpstation, third-party asbestos air monitoring may be required unless a work practice variance isrequested and pre-approved by SCDHEC.

A copy of this report must be submitted to SCDHEC at least ten (10) working days prior todemolition when applying for a demolition permit. Note that a separate demolition permit will berequired for each unattached structure.

It should be noted that suspect materials, other than those identified during these surveys, mayexist within the structures. If additional suspect materials are identified during demolition orabatement activities, those materials should be assumed to be asbestos-containing untillaboratory analysis demonstrates otherwise. Federal, state, and local regulations should bereferred to in order to verify compliance before any actions are initiated on an ACM.
