10 Introduction

11 Background

The Norwood PCH Site is located in the town of Norwood Norfalk County Hauachueetta approximately 14 milea southwest of the City of Boaton The 26 acre aite coneieta of several parcels of land including induatrhlcommerchl property auociated parking and adjacent fields The aite ia bordered to the north by 11eadow Brook to the aut by the heavily commercial Us Route 1 and the Dean Street acceaa road to the south by Dean Street and to the west by Pelhna Road

Contallination at the Norwood PCB Site originated from diapoaal practices centered at the building nov owned by Grant Gear Works Inc The building was constructed in 1942 by Bendix Aviation Corporation to produce navigational control systems and conduct electronic research for the us Navy In October 1947 the land waa purchased by the Tobe Deutschman Corporation to bullanuhcture electrical equipaent including capacitors and transforra The building waa later ovned and operated by Cornell-Dubilier Blectronica Inc who llanufactured electrical co11ponenta followed by Arrow Hart Corporation for the aanufacturing of electric boxea and electric rhting Grant Gear Works Inc haa owned and operated a chine ahop for the production of industrial geara since 1980

Throuohout the hiatory of the site the progreu of re-dial work at the Norwood PCB Site h generated significant interest both fra- the local clthena and political officials Aa a reault in order to expedite the proceaa EPA haa attebullpted to uae reaulta fr011 non-RIFS inveatigationa In particular 11n EC Jordan atudy perforMd in lJ83 focused on poaaible PCB contaaination within the Grant Gear building Swipe aa-plea were taken of the building aurfacea including floors roof beau and walla Indoor air aaaplea were alao taken and analyzed for PCBa The air aa-ple detection libullits reported by EC Jordan in their 1983 atudy were deterbullined by the Agency for Toxic Subatancea and Dieeue Registry (ATSDR) and EPA to be above the reconuHnded NIOSH criteria Therefore EPA deterained there waa a need to perforbull additional air sampling at lower detection Uaita and collect additonal wall and machine aurface wipe aaaplea to confir111 EC Jordans 1983 reaulta

12 Objective

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter

10 Introduction

11 Background

The Norwood PCH Site is located in the town of Norwood Norfalk County Hauachueetta approximately 14 milea southwest of the City of Boaton The 26 acre aite coneieta of several parcels of land including induatrhlcommerchl property auociated parking and adjacent fields The aite ia bordered to the north by 11eadow Brook to the aut by the heavily commercial Us Route 1 and the Dean Street acceaa road to the south by Dean Street and to the west by Pelhna Road

Contallination at the Norwood PCB Site originated from diapoaal practices centered at the building nov owned by Grant Gear Works Inc The building was constructed in 1942 by Bendix Aviation Corporation to produce navigational control systems and conduct electronic research for the us Navy In October 1947 the land waa purchased by the Tobe Deutschman Corporation to bullanuhcture electrical equipaent including capacitors and transforra The building waa later ovned and operated by Cornell-Dubilier Blectronica Inc who llanufactured electrical co11ponenta followed by Arrow Hart Corporation for the aanufacturing of electric boxea and electric rhting Grant Gear Works Inc haa owned and operated a chine ahop for the production of industrial geara since 1980

Throuohout the hiatory of the site the progreu of re-dial work at the Norwood PCB Site h generated significant interest both fra- the local clthena and political officials Aa a reault in order to expedite the proceaa EPA haa attebullpted to uae reaulta fr011 non-RIFS inveatigationa In particular 11n EC Jordan atudy perforMd in lJ83 focused on poaaible PCB contaaination within the Grant Gear building Swipe aa-plea were taken of the building aurfacea including floors roof beau and walla Indoor air aaaplea were alao taken and analyzed for PCBa The air aa-ple detection libullits reported by EC Jordan in their 1983 atudy were deterbullined by the Agency for Toxic Subatancea and Dieeue Registry (ATSDR) and EPA to be above the reconuHnded NIOSH criteria Therefore EPA deterained there waa a need to perforbull additional air sampling at lower detection Uaita and collect additonal wall and machine aurface wipe aaaplea to confir111 EC Jordans 1983 reaulta

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter

or PCB vapors to be emitted in t o the air ItAamp sionificantly reduced Therefore migration of PCBs from outside the building into the work apace was probably not the cont ributing source but rather aourcea within the building

During the eight-hour sampling period eight temperature barometric preaaure and relative humidity meaaureroenu were documented Teraperature readings were obtained with a Ertco thermometer atiDOashypheric preaaure with a Taylor aneroid barometer and relative humidity with a Bacharach Instrument sling paychrOIHter

10 Introduction

11 Background

The Norwood PCH Site is located in the town of Norwood Norfalk County Hauachueetta approximately 14 milea southwest of the City of Boaton The 26 acre aite coneieta of several parcels of land including induatrhlcommerchl property auociated parking and adjacent fields The aite ia bordered to the north by 11eadow Brook to the aut by the heavily commercial Us Route 1 and the Dean Street acceaa road to the south by Dean Street and to the west by Pelhna Road

Contallination at the Norwood PCB Site originated from diapoaal practices centered at the building nov owned by Grant Gear Works Inc The building was constructed in 1942 by Bendix Aviation Corporation to produce navigational control systems and conduct electronic research for the us Navy In October 1947 the land waa purchased by the Tobe Deutschman Corporation to bullanuhcture electrical equipaent including capacitors and transforra The building waa later ovned and operated by Cornell-Dubilier Blectronica Inc who llanufactured electrical co11ponenta followed by Arrow Hart Corporation for the aanufacturing of electric boxea and electric rhting Grant Gear Works Inc haa owned and operated a chine ahop for the production of industrial geara since 1980

Throuohout the hiatory of the site the progreu of re-dial work at the Norwood PCB Site h generated significant interest both fra- the local clthena and political officials Aa a reault in order to expedite the proceaa EPA haa attebullpted to uae reaulta fr011 non-RIFS inveatigationa In particular 11n EC Jordan atudy perforMd in lJ83 focused on poaaible PCB contaaination within the Grant Gear building Swipe aa-plea were taken of the building aurfacea including floors roof beau and walla Indoor air aaaplea were alao taken and analyzed for PCBa The air aa-ple detection libullits reported by EC Jordan in their 1983 atudy were deterbullined by the Agency for Toxic Subatancea and Dieeue Registry (ATSDR) and EPA to be above the reconuHnded NIOSH criteria Therefore EPA deterained there waa a need to perforbull additional air sampling at lower detection Uaita and collect additonal wall and machine aurface wipe aaaplea to confir111 EC Jordans 1983 reaulta

12 Objective

The purpo8e of thia study waa to collect sufficient quality PCB air data over an 1-hour work day at four loc11t1ona within the building to evaluate the riaka to worken fra- exposure to PCBa In addition ten wipe aaaplea were obtained frobull wall and bullachine aurfacea in

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter

or PCB vapors to be emitted in t o the air ItAamp sionificantly reduced Therefore migration of PCBs from outside the building into the work apace was probably not the cont ributing source but rather aourcea within the building

10 Introduction

11 Background

The Norwood PCH Site is located in the town of Norwood Norfalk County Hauachueetta approximately 14 milea southwest of the City of Boaton The 26 acre aite coneieta of several parcels of land including induatrhlcommerchl property auociated parking and adjacent fields The aite ia bordered to the north by 11eadow Brook to the aut by the heavily commercial Us Route 1 and the Dean Street acceaa road to the south by Dean Street and to the west by Pelhna Road

Contallination at the Norwood PCB Site originated from diapoaal practices centered at the building nov owned by Grant Gear Works Inc The building was constructed in 1942 by Bendix Aviation Corporation to produce navigational control systems and conduct electronic research for the us Navy In October 1947 the land waa purchased by the Tobe Deutschman Corporation to bullanuhcture electrical equipaent including capacitors and transforra The building waa later ovned and operated by Cornell-Dubilier Blectronica Inc who llanufactured electrical co11ponenta followed by Arrow Hart Corporation for the aanufacturing of electric boxea and electric rhting Grant Gear Works Inc haa owned and operated a chine ahop for the production of industrial geara since 1980

Throuohout the hiatory of the site the progreu of re-dial work at the Norwood PCB Site h generated significant interest both fra- the local clthena and political officials Aa a reault in order to expedite the proceaa EPA haa attebullpted to uae reaulta fr011 non-RIFS inveatigationa In particular 11n EC Jordan atudy perforMd in lJ83 focused on poaaible PCB contaaination within the Grant Gear building Swipe aa-plea were taken of the building aurfacea including floors roof beau and walla Indoor air aaaplea were alao taken and analyzed for PCBa The air aa-ple detection libullits reported by EC Jordan in their 1983 atudy were deterbullined by the Agency for Toxic Subatancea and Dieeue Registry (ATSDR) and EPA to be above the reconuHnded NIOSH criteria Therefore EPA deterained there waa a need to perforbull additional air sampling at lower detection Uaita and collect additonal wall and machine aurface wipe aaaplea to confir111 EC Jordans 1983 reaulta

12 Objective

The purpo8e of thia study waa to collect sufficient quality PCB air data over an 1-hour work day at four loc11t1ona within the building to evaluate the riaka to worken fra- exposure to PCBa In addition ten wipe aaaplea were obtained frobull wall and bullachine aurfacea in

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter

34 Indoor PCB Air Saaplino Results and Conclulio na

The air data collected on Hay 24 1989 inside the Grant Gear building are presented on Table 2 The quality control data presented in Section 33 indicates the data are of acceptable quality to adequately represent the average PCB concentration worken were exposed to over

~~e~~t~o~~es~i~n~=~i~~~m i~~ ~~~Js t~f3~BuSo~~~ing 23 ugbull3 Samples were also analyzed for the following PCB Aroclonl 1016 1221 1232 1242 1248 1260 1262 and 1268 no ne of which were identif ied above their lower limite o f detection(0015 ug 113)

The aa~~p1ea collected at each o f t he five sampling locations inside the Grant Gear building had concentntions of PCB Aroclor-1254 3 to 7 tiMs higher than NIOSHs reoccupancy guidline cri teria 05 ugm3 However the levels were well below OSHA s threshold liait valut-tibulle weighted average(TLV-TUA) concentration 05 mg113(500 ugmJ) The source of PCB Aroclor-1254 contributing to the air levela detected inside the building can not be determined with any certainty whether they are associated with PCB conta11ination inside or outside the building However given the major PCB conta~~ination problea h been identified to exist in soils outside the building and the fact that the ground was saturated fro111 the rain falling during the sa~QPling event the potential for PCB particulate matter
