Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

UJiaamp the information ptbered from aile IIUdieo and other technical documeotl EPA identified rentedial reoponae objectivs for the deanup for the Old Sprinpeld Landfill lite The deanup objecdveo are lilted below

- the 1ealtbinJ of aoU contamlnantl to the IJOUndwater Prevent the m9ation of concaminated lfOUIdwlter to the rest oftheWW Prewsnt contact with contaminated 10D or leachate that may

Prevent further miantion of contaminated JrOUndwater offaile Prevent the uncontrolled emiuion of landfill paes containing hazardous lllbotanceo

~middotmiddot- shy

To meelt theoe objectives EPA hu -gtlilhed site-specific tlrJOlt cleanup leYoJs that will be protOctive of public health and the environmenL The deanup Ieveii for lfOUIKiwater were presented in the fint ROD The contaminated IJOundwaler lhall be treated to meet Muimum Contaminant Levels (MCU) at the leachate 1eep1 and at the auaction wells oo-aite MCU are the standards used to determioe the leYel to which a particular contaminant must be reduced to ensure adequate protection of current and future public health The source control operable UDit lhould uaist in the achievement of the campeanup levels for aroundwater by preventinamp the continued contamination of JfOundwater from contamina in the The ooune control remedy should abo be desianed to prevent exposure to landfill au emissions and contaminated soDs that represent an unacceptable cancer risk

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

Actual or threatened releasea of bazardouiiUbatancea from this site if not addressed by the preferred alternative or one of the other active measure considered may present a current or potential threat to public health or the environment

For a complete explanation of riab poled by contamination at the Old Sprinjlield landfill aile pleue refer to the 1988 EA and FS both of which are avwble at the infonnation repository at the Sprinlfield Public Library In addition the 1990 FFS containamp a reviled risk ~~~ea~ment Ibis risk uaeument wu not properly prepared and is not appropriate for evaluating alternatives (see the Detailed Evaluation Memo for a more in-depth analysis of this risk assessment)

Proposed Cleanup Objectives and Levels

When the action described in the first ROD il implemented the risk from potential espoaure to the air emiuiona from the leachate seeps will be prevented Once the leachate collection l)ltem il in place no contaminated IWface water will be in contact with the air The implementation of the action delaibed in the first ROD will ooly partially addreu the IJOundwater rilb and will not reduce the rilb auociated with direct cootact or 1andfiU emiaiona The second operable unit Meb to addreu the rilb wn from direa 00111ac1 with oontaminated aoil inhalation of laDdfill pa and iqatioa of contaminated water

UJiaamp the information ptbered from aile IIUdieo and other technical documeotl EPA identified rentedial reoponae objectivs for the deanup for the Old Sprinpeld Landfill lite The deanup objecdveo are lilted below
