INDIANA KEN DAVIS ASSOCIATES SOUTH BEND INDIANA FZEDA PROJECT NUMBER 30-1173 SEPTEMBER 30 1988 KEN S ASSOCIATES TABLE OF CONTENTS EXECUTIVE SUMMARY II PROJECT OBJECTIVES III GENERAL COMMENTS IV DISCUSSION OF RESULTS CONCLUSIONS VI GENERAL RECOMMENDATIONS 10 KEN ASSOCIATES EXECUTIVE SUMMARY site investigation of the Transwestern building was completed by Ken Davis Associates KEDA on September 26 and 28 1988 for the City of South Bends Department of Economic Development The purpose of site investigation which is also known as an environmental audit is to identify contamination and hazardous materials The site investigation conducted by KEDA consisted of visual inspection of the interior and exterior of the building The interior inspection included walk through of the building from the basement through the fourth floor The interior of the buildings walls and ceilings were not inspected The findings are summarized below and are discussed in Section IV of the report The owners responsibility for the cost of the site cleanup is also discussed in Section IV The results of the investigation will be utilized to recommend further data collection and/or possible remediation The preliminary assessment was the extent of the work conducted by KEDA on the Transwestern building Asbestos like material was observed from the basement and all four floors above Approximately 10000 linear feet ws identified The asbestos served as insulation on the metal piping in the building The state of Indiana and tJSEPA will require notification if the asbestos is to be removed prior to KEN ASSOCIATES renovation or if the building is to be demolished Wooden 1brickst were found on the first and th.ird floors of the building and appear to be treated with creosote The creosote has apparently contaminated the soil material below the ubricksu The extent of subsurface material contamination within the building will require further investigation Soil gas analysis for detection of petroleum residuals were conducted on the inside of the building The exterior of the building was tested in the grassy area along the east and west sides Soil gas analysis readings of 25 ppm hexane indicate background levels of hydrocarbons present on the site in the areas tested Hand augering was performed at three selected locations where hexane readings of ppm were recorded at the surface by the soil gas meter The hand augered locations were tested for further traces of hydrocarbons Hexane levels of 10 ppm were recorded at depth of approximately one foot by the soil gas meter at each location The increase in concentration indicates that source of hydrocarbons may exist below the site or that the ground water may be transporting contaminants under the site These levels arc still considered bac1aronc cy the EPA because of the location of the sample points The removal of the wooden bricks contaminated soil if present empty solvent cans 55 gallon drums containing liquid and trash will require disposal at hazardous and nonhazardous landfills ASSOCIATES ii The exterior of the building was also visually inspected Electrical capacitors which may contain PCBs were located on the west side of the exterior of the building Capacitors which contain PCBs must be disposed of by incineration KEDA recommends that the next phase of the investigation for the Tranowestern building consist of laboratory verification of the suspected asbestos material and contents of the electrical capacitors soil and ground water analysis in the areas with 10 ppm readings historical search to determine previous uses of the property and to determine the chemicals which may have been utilized at the site The cost to remove the contaminated material from the building if it is to be renovated or demolished is estimated between $300000.00 and $500000.00 These preliminary cost estimates are based on incineration and disposal costs at facilities located in Ft Wayne Indiana and Chicago Illinois II PROJECT OBJECTIVES The objectives of this project were to Visually identify areas either inside or outside the building which have asbestos material utilized as insulation Recommend general disposal methods and costs for asbestos and _____________KENE ASSOCIATES PCB removal if these materials are present Determine with the aid of soil gas analysis if hydrocarbons are present in the subsurface inside and outside the building Estimate the cost to remove the contaminated so.il inside and outside the building Estimate the cost to remove the creosote treated bricks on the first floor of the building Identify the general responsibilities of the property owners and their liabilities regarding contaminated buildings and soil III GENERAL COMMENTS site investigation of the Transwestern building was completed by Ken Davis Associates Inc KEDA on September 26 and 28 1988 The site investigation consisted of visual identification of potentially hazardous materials on the interior and exterior of the building The interior inspection was limited to visual inspection of the exposed antercr walls ceilings and floors The inventory of potentially hazardous material was confined to estimating the quantity of asbestos like material capacitors and empty and filled containers No asbestos testing was completed during this portion of the _KENE ASSOCIATES investigation The testing for hydrocarbons in the subsurface was limited to the first floor inside the buildinq and outside the basement and areas adjacent east and west side to the building except where the removal of wooden bricks was possible In those areas where removal of bricks was possible exposed material beneath the tTbricksu was tested for the presence of hydrocarbons The three areas which contained the highest surficial hydrocarbon readings during the preliminary scan outside the building were hand augered one foot below the surface and the exposed soil was retested for the presence of hydrocarbons The soil gas analysis was performed utilizing Model 90 gas detector which operates with gas sensitive semiconductor sensor When combustible or reducing gases are absorbed on the sensor surface marked decrease of electrical resistance occurs This decrease is registered by the instrument and calibrated by the gauge as ppm hexane The advantage of this sensing principle for soil gas surveys is that the instrument is sensitive to wide range of hydrocarbon volitles from methane and gasoline to diesel fuel and motor oil IV DISCUSSION OF RESULTS The visual inspection and soil gas survey of the Transwestcrn building resulted in the location of several areas _________________________________________KENE ASSOCIATES which contain potentially hazardous materials Asbestos Fibrous material which was observed on piping during the interior inspection of the building was tentatively identified as asbestos There were approximately 8000 to 12000 linear feet of the suspected asbestos insulating the piping inside the building The state of Indiana has jurisdiction over the removal and disposal of asbestos There are no regulations which require the removal of asbestos from buildings except in schools The regulations are in place to govern the removal of asbestos to decrease liability during the renovation or demolition of building containing asbestos The maximum amount of asbestos material which can go unreported to the state during removal is 260 linear feet 160 cubic feet or material which contains less than asbestos by weight If the building contains greater than the amounts listed above the state must be notified of the intent to remove the asbestos 10 days prior to removal or demolition plan must also be filed with the state describing the removal methods to be used Requirements for personnel safety during removal of the asbestos include cartridge respirators protective clothing and gloves Containerized breathing is required if the fiber-count per cubic foot of air exceeds the state limit Asbestos can be disposed of in municipal land fill The disposal requires the property owner to acquire special permit ____________________________________________KENE ASSOCIATES Potentially Hazardous Material One potentially hazardous material which was identified were the wooden bricks that were found on the first and third floors The estimated number of wooden bricks on the first floor is 450000 The estimated number of wooden bricks on the third floor is 50000 These bricks are approximately 8x 3x 211 and appear to be treated with creosote The material beneath the wooden bricks when tested for hydrocarbons utilizing the soil gas meter registered range of ppm to ppm of hexane The readings are near background and indicate that contamination is probably due to the bricks Several of 55 gallon drums and solvent spray cans were located inside the building The disposal of the containers can be accomplished in municipal landfill if laboratory testing indicates no hazardous materials are present The electrical capacitors if determined to contain PCBs must be disposed of by hazardous waste land fill which has the ability to incinerate Soil Gas Analysis Three hand auger borings were completed during lhe exterior inspection of the building in the areas which contained the most significant level of hydrocarbon readings At death of approximately one foot below the surface the hydrocarbon readings increased from ppm Hexane to 20 ppm Hexane The higher meter readings indicate an inoreace in concentration of hydrocarbons beneath the surface These readings are considered _________________________________________KENE AssociATEs further delineation of the background level because of the sample points However soil borings and laboratory analysis will confirm these readings Owners Responsibility/Liability The site investigation has identified extensive asbestoslike material on the piping on all floors of the building The asbestos removal is the owners responsibility and is estimated to cost approximately $20.00 per linear foot or $200000.00 This reflects the removal transportation and disposal costs An asbestos removal plan must be prepared and submitted to the Indiana Department of Environmental Management IDEM 10 days prior to the removal and special permit must be obtained to bury the asbestos material in landfill The estimated cost to prepare the permit is $5000.00 The removal and transportation of the wooden bricks to hazardous waste land fill is estimated to cost between $50000.00 and $100000.00 The cost to incinerate and bury 1he ashes of the capacitors which may contain P03s will he will be approximately $1.25 per pound or $200.00 each The cost to remove and bury empty 55 gallon drums is approximately $.09 per pound If the drums are filled with liquid that must be disposed of at hazardous waste land fill the cost can range from $02.00 per 55 gallon drum to $175.00 per drum These costs reflect stabilization of the fluid and/or incineration _________________________________________________________KENE ASSOCIATES Contaminated soil which must be taken to hazardous waste land fill for disposal is estimated to cost between $135.00 per ton for burial and $570.00 per cubic yard for material which must be incinerated These costs do not include the transportation cost to the landfill or incinerator Incineration would be performed at Chemical Waste Managements facility outside Chicago Illinois Transportation costs are approimately $600.00 per trip This hauler will remove of 80 55 gallon drums or 30 cubic yard container Landfill disposal for contaminated soil could be performed by Chemical Waste Managements facility in Ft Wayne Indiana The estimated cost for transportation is $450.00 for 80 55 gallon drums or 30 cubic yard container Asbestos and nonhazardous material disposal can be completed by sanitary or municipal land fill The local facility which could be involved is the Prarieview Landfill CONCLUSIONS The fibrous material which may be asbestos was utilized as insulating material on the pipes in the interior of the building Surficial hexane readings ranging from 25 ppm were recorded on the interior of the first floor below the wooden bricks along the grounds adjacent to the east and west walls of the building Hexane readings ranged from 5-10 __________________________________________KENE ASSOCIAThS ppm from depth of approximately foot These are background readings Capacitors were located along the west side of the building which may contain PCBs Sealed containers of asbestos roofing material and 55 gallon drums containing liquid were observed on the site VI RECOMMENDATIONS KEDA recommends that the following steps be taken Laboratory analysis to positively identify the asbestoslike insulating material The liquid contained in the 55 gallon drums should be tested for chemical constituents and relative concentrations The soil and material on the interior and exterior of the building produced 2-10 ppm Hexane readings on the soil gas meter These readings should be compared to the soil gas data acquired by EIS The electrical capacitors on the west side of the building should be tested for 905$ The chemicals used to treat the wooden bricks should be identified by laboratory analysis 10 KEN ASSOCIATES KEN DAVIS
