Time critical reirnoval actions (TCRA) and a NTCRA have been irnpleirnented at the site These actions are described further below The Rl will evaluate any site-related contamination that was not remedied by t h e TCRA or MTCRA and the FS will evaluate the adequacy of these actions as permanent remedies
iJUi Time-Crit ic I Removal Action
A TCRA was conducted at the si i te in 1999 and 2000 to reduce the immediate human health threat to residents on and near the site The TCRA mcludled the following
laquo Removal of approximately fi acres of yndeirgrowth from the main part of the site
ltgt Construction of fenc ing in the maim part of Ihe site and in residential areas adjoining Allenda e Pond to restrict access to potential ly conUirninated areas
ltgt Construct ion o f an inte r ini prolec tive cap (J nterim Cap laquo I ) in a formerly wooded area immediately south of the Centredale Manor parking lot (Figure 2) Thus area is prone to flooding and had Ihe highest concent r a t ions of c l ioKi in and PCBs in surface soil alilne site

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Time critical reirnoval actions (TCRA) and a NTCRA have been irnpleirnented at the site These actions are described further below The Rl will evaluate any site-related contamination that was not remedied by t h e TCRA or MTCRA and the FS will evaluate the adequacy of these actions as permanent remedies
iJUi Time-Crit ic I Removal Action
A TCRA was conducted at the si i te in 1999 and 2000 to reduce the immediate human health threat to residents on and near the site The TCRA mcludled the following
laquo Removal of approximately fi acres of yndeirgrowth from the main part of the site
ltgt Construction of fenc ing in the maim part of Ihe site and in residential areas adjoining Allenda e Pond to restrict access to potential ly conUirninated areas
ltgt Construct ion o f an inte r ini prolec tive cap (J nterim Cap laquo I ) in a formerly wooded area immediately south of the Centredale Manor parking lot (Figure 2) Thus area is prone to flooding and had Ihe highest concent r a t ions of c l ioKi in and PCBs in surface soil alilne site

ltgt Placement of rip rap a long the shore of the iriveir to i so la t e contaminated soils and prevent erosion
These contaminated soil areas and need for Uie caps were evaluated as part of the USEPA Region I Action Memorandum dated May 4 IW) as Eirnended Sep tember Ki 11999 and J u n e 1 2000 Eind were addressed under the TCRA in 2000 The primaiy pinrpose of Ihe interims caps is to min imize human exposure t o conlamirialed soils Evaluation of prolecliiveness from exposure to those contaminated soils Eind integrity of the interim caps r i p i r a p a n d existing pavement Eilllie si lew ill be included in the FS as part of select ion o f the c ornponents o f Ihe peniiament re rnedy A n othe r TC RA is under cons ideirat ion in 2003 to reduce the immediate h u m a n health risk firom exposure to dioxin in tailrace soil- on the eEistside of the source area

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Time critical reirnoval actions (TCRA) and a NTCRA have been irnpleirnented at the site These actions are described further below The Rl will evaluate any site-related contamination that was not remedied by t h e TCRA or MTCRA and the FS will evaluate the adequacy of these actions as permanent remedies
iJUi Time-Crit ic I Removal Action
A TCRA was conducted at the si i te in 1999 and 2000 to reduce the immediate human health threat to residents on and near the site The TCRA mcludled the following
laquo Removal of approximately fi acres of yndeirgrowth from the main part of the site
ltgt Construction of fenc ing in the maim part of Ihe site and in residential areas adjoining Allenda e Pond to restrict access to potential ly conUirninated areas
ltgt Construct ion o f an inte r ini prolec tive cap (J nterim Cap laquo I ) in a formerly wooded area immediately south of the Centredale Manor parking lot (Figure 2) Thus area is prone to flooding and had Ihe highest concent r a t ions of c l ioKi in and PCBs in surface soil alilne site

ltgt Placement of rip rap a long the shore of the iriveir to i so la t e contaminated soils and prevent erosion
These contaminated soil areas and need for Uie caps were evaluated as part of the USEPA Region I Action Memorandum dated May 4 IW) as Eirnended Sep tember Ki 11999 and J u n e 1 2000 Eind were addressed under the TCRA in 2000 The primaiy pinrpose of Ihe interims caps is to min imize human exposure t o conlamirialed soils Evaluation of prolecliiveness from exposure to those contaminated soils Eind integrity of the interim caps r i p i r a p a n d existing pavement Eilllie si lew ill be included in the FS as part of select ion o f the c ornponents o f Ihe peniiament re rnedy A n othe r TC RA is under cons ideirat ion in 2003 to reduce the immediate h u m a n health risk firom exposure to dioxin in tailrace soil- on the eEistside of the source area

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Time critical reirnoval actions (TCRA) and a NTCRA have been irnpleirnented at the site These actions are described further below The Rl will evaluate any site-related contamination that was not remedied by t h e TCRA or MTCRA and the FS will evaluate the adequacy of these actions as permanent remedies
iJUi Time-Crit ic I Removal Action
A TCRA was conducted at the si i te in 1999 and 2000 to reduce the immediate human health threat to residents on and near the site The TCRA mcludled the following
laquo Removal of approximately fi acres of yndeirgrowth from the main part of the site
ltgt Construction of fenc ing in the maim part of Ihe site and in residential areas adjoining Allenda e Pond to restrict access to potential ly conUirninated areas
ltgt Construct ion o f an inte r ini prolec tive cap (J nterim Cap laquo I ) in a formerly wooded area immediately south of the Centredale Manor parking lot (Figure 2) Thus area is prone to flooding and had Ihe highest concent r a t ions of c l ioKi in and PCBs in surface soil alilne site

ltgt Placement of rip rap a long the shore of the iriveir to i so la t e contaminated soils and prevent erosion
These contaminated soil areas and need for Uie caps were evaluated as part of the USEPA Region I Action Memorandum dated May 4 IW) as Eirnended Sep tember Ki 11999 and J u n e 1 2000 Eind were addressed under the TCRA in 2000 The primaiy pinrpose of Ihe interims caps is to min imize human exposure t o conlamirialed soils Evaluation of prolecliiveness from exposure to those contaminated soils Eind integrity of the interim caps r i p i r a p a n d existing pavement Eilllie si lew ill be included in the FS as part of select ion o f the c ornponents o f Ihe peniiament re rnedy A n othe r TC RA is under cons ideirat ion in 2003 to reduce the immediate h u m a n health risk firom exposure to dioxin in tailrace soil- on the eEistside of the source area

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Time critical reirnoval actions (TCRA) and a NTCRA have been irnpleirnented at the site These actions are described further below The Rl will evaluate any site-related contamination that was not remedied by t h e TCRA or MTCRA and the FS will evaluate the adequacy of these actions as permanent remedies
iJUi Time-Crit ic I Removal Action
A TCRA was conducted at the si i te in 1999 and 2000 to reduce the immediate human health threat to residents on and near the site The TCRA mcludled the following
laquo Removal of approximately fi acres of yndeirgrowth from the main part of the site
ltgt Construction of fenc ing in the maim part of Ihe site and in residential areas adjoining Allenda e Pond to restrict access to potential ly conUirninated areas
ltgt Construct ion o f an inte r ini prolec tive cap (J nterim Cap laquo I ) in a formerly wooded area immediately south of the Centredale Manor parking lot (Figure 2) Thus area is prone to flooding and had Ihe highest concent r a t ions of c l ioKi in and PCBs in surface soil alilne site
i1 Construiclion of a second interim cap (Inlerim Cap n2) between t h e WoonasquatiLicltel River and the Cenlredale Manor building (Figuire 2) This area is also pirone to flooding and contained elevated concentrations of dioxin in surface soils ( i e greater than I part per b i l l i o n [ppb]) A flood control berrn was also constructed to prevent erosion of t h e cap
ltgt Placement of rip rap a long the shore of the iriveir to i so la t e contaminated soils and prevent erosion
These contaminated soil areas and need for Uie caps were evaluated as part of the USEPA Region I Action Memorandum dated May 4 IW) as Eirnended Sep tember Ki 11999 and J u n e 1 2000 Eind were addressed under the TCRA in 2000 The primaiy pinrpose of Ihe interims caps is to min imize human exposure t o conlamirialed soils Evaluation of prolecliiveness from exposure to those contaminated soils Eind integrity of the interim caps r i p i r a p a n d existing pavement Eilllie si lew ill be included in the FS as part of select ion o f the c ornponents o f Ihe peniiament re rnedy A n othe r TC RA is under cons ideirat ion in 2003 to reduce the immediate h u m a n health risk firom exposure to dioxin in tailrace soil- on the eEistside of the source area

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Time critical reirnoval actions (TCRA) and a NTCRA have been irnpleirnented at the site These actions are described further below The Rl will evaluate any site-related contamination that was not remedied by t h e TCRA or MTCRA and the FS will evaluate the adequacy of these actions as permanent remedies
iJUi Time-Crit ic I Removal Action
A TCRA was conducted at the si i te in 1999 and 2000 to reduce the immediate human health threat to residents on and near the site The TCRA mcludled the following
laquo Removal of approximately fi acres of yndeirgrowth from the main part of the site
ltgt Construction of fenc ing in the maim part of Ihe site and in residential areas adjoining Allenda e Pond to restrict access to potential ly conUirninated areas
ltgt Construct ion o f an inte r ini prolec tive cap (J nterim Cap laquo I ) in a formerly wooded area immediately south of the Centredale Manor parking lot (Figure 2) Thus area is prone to flooding and had Ihe highest concent r a t ions of c l ioKi in and PCBs in surface soil alilne site
i1 Construiclion of a second interim cap (Inlerim Cap n2) between t h e WoonasquatiLicltel River and the Cenlredale Manor building (Figuire 2) This area is also pirone to flooding and contained elevated concentrations of dioxin in surface soils ( i e greater than I part per b i l l i o n [ppb]) A flood control berrn was also constructed to prevent erosion of t h e cap
ltgt Placement of rip rap a long the shore of the iriveir to i so la t e contaminated soils and prevent erosion
These contaminated soil areas and need for Uie caps were evaluated as part of the USEPA Region I Action Memorandum dated May 4 IW) as Eirnended Sep tember Ki 11999 and J u n e 1 2000 Eind were addressed under the TCRA in 2000 The primaiy pinrpose of Ihe interims caps is to min imize human exposure t o conlamirialed soils Evaluation of prolecliiveness from exposure to those contaminated soils Eind integrity of the interim caps r i p i r a p a n d existing pavement Eilllie si lew ill be included in the FS as part of select ion o f the c ornponents o f Ihe peniiament re rnedy A n othe r TC RA is under cons ideirat ion in 2003 to reduce the immediate h u m a n health risk firom exposure to dioxin in tailrace soil- on the eEistside of the source area

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Time critical reirnoval actions (TCRA) and a NTCRA have been irnpleirnented at the site These actions are described further below The Rl will evaluate any site-related contamination that was not remedied by t h e TCRA or MTCRA and the FS will evaluate the adequacy of these actions as permanent remedies
iJUi Time-Crit ic I Removal Action
A TCRA was conducted at the si i te in 1999 and 2000 to reduce the immediate human health threat to residents on and near the site The TCRA mcludled the following
laquo Removal of approximately fi acres of yndeirgrowth from the main part of the site
ltgt Construction of fenc ing in the maim part of Ihe site and in residential areas adjoining Allenda e Pond to restrict access to potential ly conUirninated areas
ltgt Construct ion o f an inte r ini prolec tive cap (J nterim Cap laquo I ) in a formerly wooded area immediately south of the Centredale Manor parking lot (Figure 2) Thus area is prone to flooding and had Ihe highest concent r a t ions of c l ioKi in and PCBs in surface soil alilne site

ltgt Placement of rip rap a long the shore of the iriveir to i so la t e contaminated soils and prevent erosion
These contaminated soil areas and need for Uie caps were evaluated as part of the USEPA Region I Action Memorandum dated May 4 IW) as Eirnended Sep tember Ki 11999 and J u n e 1 2000 Eind were addressed under the TCRA in 2000 The primaiy pinrpose of Ihe interims caps is to min imize human exposure t o conlamirialed soils Evaluation of prolecliiveness from exposure to those contaminated soils Eind integrity of the interim caps r i p i r a p a n d existing pavement Eilllie si lew ill be included in the FS as part of select ion o f the c ornponents o f Ihe peniiament re rnedy A n othe r TC RA is under cons ideirat ion in 2003 to reduce the immediate h u m a n health risk firom exposure to dioxin in tailrace soil- on the eEistside of the source area

The following is an ini t ia l evaluation of the nature and extent of contaminat ion based on data collected a t t h e site from 1997 through 2001 A del ailed an ally sis that includes all data collected lor Ihe Rl wi l l be provided in ihe R l report
321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l

321 Soiii Soil sampling efforts in the sou nee area have foe used on characterising the distribution of d iox in which was identified as the pri ma ry conl am inant o f concern in the Meal th Consullal ion for the s il e (US Department of Heath and Human Services Agency for Toxic Substances and Disease Registry [ A T S D R ] I9W) A subset of soil samples was also analyzed for other si te-related chemicals Elevated levels of d i o x i n PCBs VOCs SVOCs and selected metals have been identified i n site soi ls Dioxin contamination is widespread w i t h levels up lo 140 ppb in surface soil ConcenlcEitions in subsurface soils are generally lower (IT Group 2000) Total PCBs total VOCs and total SVOCs have been measured at concentrations up lo 1300 parts per mil l ion (pprn) 10000 pprn and 1800 pprn respectively (US EPA 1999)
Dioltin concentration data are typically reported on an i n d i v i d u a l congener basis and converted to a 2378-leirEicliiloirodibenizo-p-dioxin (TCDD) TEQ concentrat ions As noted i n Section 231 a preliminary cleanup level of I ppb dioxin as EI TEQ1 should be used for res iden t ia l properties (US1EPA 1998) This cleanup level was recommended as the basis for the TCRA in the source area (ATSDR 1999) Figures 8 and 9 show Ihe locations where Ihe dioxin TEQ1 exceeds I ppb i n Ihe Allendale and Ly man Mill areas respectively In the source area most of the soils with dioxin TIEQs exceeding 1 ppb are found beneath the inlerim caps (sediment data are sunrirnanzed in Section 32J)
The d i s t r i b u t i o n of d i o x i n in the lailrace is shown in more detai l in Figure 10 and is described in detail in the Interim Data Col lection Work Plan (Battelle 2()()2a) Briefly i he distribution of dioxin greater tham I ppb TEQ in the lailrace is patchy and discontinuous Addit ional data collected as part of the Interim Data Col lec t ion effort ( Section 43 4) wi l l better def ine the horizontal and vert ical dislribulion of dioxin in the lailrace These data w i l l be reported in the R l
Figure 111 shews source area soil sample locations in areas located under existing paved surfaces ( i e not located under the inlerim soil caps or in the tailrace) Sample locations shown in red correspond wi th samples taken under exist ing paved surfaces from 0-2 fi with conlaminaitit concentrations that e i t he r exceed Ihe State of Rhode Is land direct exposure c r i t e r i a for residential soils at contaminated sites (Rhode Island Re mediation Regulations R u l e 802 B) or the preliminary cleEinup level of I ppb TEQ for dioxin (USEPA 1998) Sample locat ions wi th shallow soils exceeding the Rhode Island direct exposure criteria are concentrated in the Centredale Manor north and south parking lots although shallow soils in several local ions at t h e Brook Village parking lot also exceed direct exposure criteria
