The IRA Plan and IRA Plan Amendment were approved by the DEP in a letter dated August 18, 2006 (Appendix A). This IRA Status Report has been prepared in accordance with the applicable requirements of the MCP. In accordance with 310 CMR 40.0424, an IRA Transmittal Form (BWSC-105) has been completed for the Site. A copy of the form is included ih Appendix A. This IRA Status Report covers the pi/riod April 20, 2007 through October 3, 2007 at the Site. I . I Description of the Release and Site Conditions The release at this Site can generally be described as disposal of industrial waste materials,, demolition debris, and common refuse in an unwegulated landfill within and along the former raceway leading to the Cutlery Building. The primary contaminants of concern are the metals arsenic, chromium, nickel, -and lead. Other metals, PCBs, and some petroleum products have also been found .at the Site above acceptable standards. This IRA specifically addresses the. control of metals found within soil and fill materials on the bank of the Mill River west of the Cutlery Building and the former Firehouse within AOC- I and the relocation of these soils to the existing soil stockpile within AOC-2. The area of the IRA is shown in relation to the entire $ite in Figure 2. AOC- I Parking Lots In the Summer of 2005, metals-impacted soil was discovered on the bank of the Mill River behind the Cutlery and Firehouse buildings, west of the parking lots, indicating that AOC-I extends further to the west than previously thought. This meant that simply paving the parking lot surface would not provide a sufficient barrier to isolate this soil..The concentrations of chromium exceed Imminent Hazard (1,000 mg/kg) levels in 9 of the 15 samples collected in this area, and one of these (CB-I at 25,000 mg/kg) exceeds the UCL for chromium (I 0,000mg/kg). Results of this soil sampling are summarized in Table I . The bank of the Mill River in this location is entirely composed of fill material including a large number of boulders and concrete slabs, and is currently held in place, in part, by the roots of many mature trees. AOC-2 Filled Raceway Soil excavated at the Site in 2004 artd 2005 was stockpiled in the central portion of the Site on top of a filled portion of the former water power raceway (AOC-2). This stockpile was relatively long, tall, skinny, and was covered with plastic. In total, the stockpile was approximately 180 feet long, 25-30 feet wide and 8- I 0 feet high with a peaked ridge. A depression in thl~ n~a,~-tie-eentLr~51`ovided access to a City of Northampton sewer manhole. pjgj~jZed 1.2 Previous Related IRA Activities Checked The DEP was notified of the CB-I Imminent Hazard (IH) condition on July 28, 2005 and an Immediate Response Action (IRA) was initiated, NEE proposed the installation of "No Trespassing" signs as an appropriate mitigating measure under the IRA triggered by the IH condition. The bank of the Mill River where these samples were collected is a deeply wooded area behind the Cutlery Building parking lot, an IRA Status Report RTN # I - 13320 Former Cutlery Raceway October 3, 2007 320-360 Riverside Drive NEE Project No. 02-2053 Page 2 of 6 Northampton, Massachusetts NEw area where people do not enter and have no reason to cross. The bank down to the river is quite steep and much of it is simply impassable. The area showed no signs of activity -prior to sampling, so posting signs was considered a precautionary measure. Mr. John Bourcier of the DEP agreed that sign posting was an appropriate measure, and the signs were installed the following day, July 29, 2005. In addition to the signs, NEE also installed several short lengths of orange construction fencing in the more accessible areas of the top portion of the bank as an additional deterrent. At a follow-up site visit on August 12, 2005, Mr. Ben Fish of the DEP agreed that the sign posting and fences were adequate mitigation measures for the steep bank.. The IRA was closed on September 9, 2005. No other IRA activities have occurred for this condition. As noted in the IRA Plan (NEE June 6, 2006), NEE completed these Phase IV response actions under the IRA provisions of the MCP to assist the City of Northampton planners and Conservation Commission by gaining specific Department approval of the actions prior to their commencement. 1.3 Proposed IRA Activities (as Amended) AOC- I In all areas where exceedance of a UCL of any metal are identified, this material will be -moved to the existing soil stockpile within AOC-2, West of the Cutlery Building and Firehouse, the remaining metals- impacted soil along the bank leading clown to the Mill River will be physically stabilized in place and an AUL will be extended from the parking lots, down to the river's edge. A chain-link fence will be erected along the west side of the parking lots in AOC- I to restrict access to the bank. Cutlery Building Associates requested permission from the DEP to install afour-foot high fence along the edge of the parking lot immediately behind the buildings, including behind the old firehouse, with "No Trespassing/ Restricted Area" signs. This would be in place of the five-foot fence outlined in the IRA Plan. They believed a higher fence would be unattractive and very adversely impact their property value, and is unnecessary as a means of restricting access by the public. They believed afour-foot fence behind the buildings would be effective to deter people from climbing over the fence due to the proximity and active use of the buildings. Afive-font high chain link fence will still be installed along Riverside Drive as originally planned as this area is more accessible to the public. The DEP responded favorably to this request, issuing an approval letter dated July 19, 2007 (Appendix A). Excavated UCL soil from AOC- I will be moved 'to the existing soil stockpile within AOC-2. Based upon the distribution of sampling locations and laboratory results (CB- I to CB- 15), NEE estimates that less than 30 yd3 of soil exceeding UGL concentrations for chromium will require excavation. The surface of the bank will be stripped of small brush and vegetation, and then covered in a marker layer of bright orange, plastic, construction-type fencing that is laid down around the existing trees. The marker layer will then be covered with four to six inches of cover material and loam, then covered with erosion control landscape fabric, acid planted with materials designed to physically stabilize the bank against future erosion (IRA Plan: Figures 3, 4, and 5). A coconut bio-log will be installed at the toe of the slope within AOC-I to anchor the fabric layers and reduce possible e~~~the Mil_rer ~f-~e lower portions of the new installations. _ Digifiiz~d __ _ _--- West of the Cutlery Building where the bank is near-vertical, it is unrealisfiti~g~~~me-that-eve~our to six inches of soil will stay on the bank, Some areas of this bank are boulders, and these do not need to be covered with soil and planted. In the remaining areas, soil will be placed between the large rocks and IRA Status Report RTN #I-13320 Former Cutlery Raceway October 3, 2007 320-360 Riverside Drive NEE Project No. 02-2053 Page 3 of 6 Northampton, Massachusetts NEW ENGLAND covered with an erosion-control fabric to help hold it in place prior to being planted with materials designed to physically stabilize the bank against future erosion. At the base of established trees, the soil layer will be reduced to nothing so that the trees' root systems and trunks are not suffocated. AOC-2 The stockpile will in turn be lowered slightly, and spread out slightly to remove the high peaks and some of the steep side slopes. The stockpile will then be covered with a geotextile fabric, loam and seed. The plastic will not be replaced on top of this stockpile. Under the agreement, fabric, loam and seed was considered a better long-term cover material than plastic as it would not degrade in the sun and it would prevent contaminated soil frc~rii being blown by the wind. Percolation. of precipitation was not considered a concern as the concentrations of metals in the soil have been demonstrated not to leach in excess of the EPA land treatment concentrations. With the exception of changing the rover material on the stockpile, these actions are similar to those included in the Revised Phase IV RIP submitted to the Department on September 15, 2005. Additional chain link fence will be added to the road-side of the Site from the southerly chain link fence all the way to the northerly chain Fink fence; the entire length of AOC-2 and AOC-3. The orange plastic fencing will be moved to the river-side of the soil, stockpile, after it has been loamed and seeded. This action will completely encircle the stockpile with fencing. The goal of this IRA Plan remains to remove the most highly contaminated soil from AOC-I and then to stabilize, control and isolate the remaining concentrations of metals-impacted soil. Once this is complete; an Activity & Use Limitation will be placed on AOC-I, and NEE will file. a Class A3 Partial Response Action Outcome (RAO-P) on this portion of the Site (the Cutlery Building and Firehouse lots). The remaining Remediation Waste from AOC- I that is included in the soil stockpile located in AOC-2 will be managed as noted beltsw and included in the Class C RAO for those portions of the Site. These actions are sufficient to allow partial closure of AOC- I under 3 I 0 CMR 40.0030. 2.0 COMPLETED IRAACI"IVITIES 2.1 Soil Excavation No soil excavation activities have occurred in the period from April 20, 2007 through October 3, 2006. 2.2 Sign Posting Additional "No Trespassing" signs were added to both the street and river sides of the Site in September 2006. There are now I>~ "Posted, No Trespassing" signs around the Site: six along the edge of pavement of the Cutlery and Valley Home Improvement parking lots, a total of I I similar signs on the edge of Riverside Drive along AOG-2 and AOC-3, and three "Posted, No Trespassing" signs along the bottom edge of the levee facing the Mill River in AOC-3, with a final sign at the base of the CB- I excavation facing the River in AOC- I . 2.3 Mill River Bank Stabilizati+~n in AOC-I IRA Status Report RTN # I - 13320 October 3, 2007 ; NEE Project No. 02-2053 Page 4 of 6 n _.---- Digit'1zed __.._- -_-- ~ ~ edr ~_.-____--- heck _____--- Former Cutlery Raceway . 320-360 Riverside Drive Northampton, Massachusetts EW ENGLAND ENVIRO C. The remaining metals-impacted soil along the bank leading down to the Mill. River in AOC- I were physically stabilized in place. Orange Mastic fencing has now been installed as a marker layer on the bank surface to identify the former ground surface west of the parking lots in ACO- I . Spring flooding of the Mill River this Spring caused considerable erosion of the toe of the slope in AOC- I and over-topped the silt fence,. flattening it in many places. A flexible filter soc filled with seeded mulch was installed along the toe of the slope in this area of the Site as a replacement for the silt fence. Seeded mulch (EcoBlanketTM) was then sprayed in a layer 2-4 inches thick on the slope on top of the orange plastic fencing in AOC- I . Straw mat was stapled to the top surface of the bank, on top of the EcoBlanketTM, in some of the steeper portions of the slope to further protect the slope from erosion. The. attached photographs show various stages of this installation and the finished installation with sprouted seed. It is anticipated that some areas will require touch up this Fall, and this work is scheduled for October. The bank stabilization plan also called for planting .of dormant willow stakes which . is scheduled for November 2007. 2.4 Mill River Bank Stabilization in AOC-2 and AOC-3 The proposed stone retaining wall at the toe of the slope of the levee in AOC-3 was installed. An eroded, undercut area just above/behind this wall was filled with pea-stone to physically stabilize the bank and return the bank profile to its former slope. The entire levee bank was coated in a 2-4" layer of EcoBlanketTM, as was the top surface of the levee. The steepest sections of the levee bank were then covered with straw mat that was stapled to the ground surface in an effort to further combat erosion on the levee bank. The silt fence along the toe of the levee bank was left in place. Photographs of this area of the Site are also attached. The soil stockpile in AOC-2 has an ample crop of grass and no erosion is apparent on the sides of the stockpile. This. stockpile is solid as evidenced by the lack of evident compaction or erosion when the levee area was accessed for bank stabilization work (see below). The inevitable tire tracks across the top of the stockpile were seeded with the same EcoBlanketTM mulch material once the levee work was complete, and this area recovered anal looked as good as the rest of the stockpile within several weeks. 2.5 Remaining IRA Activities The following activities remain to be completed within AOC- I at the Site: • Several small areas remain to be paved (the extended paring lot west of the Firehouse and Cultery buildings, and the fenced storage area between Nelson Shifflett's new addition and the ,Cutlery parking lot planting bed). • A four-foot high chain-link fence will be erected along the west side of the parking lots in AOC- I to restrict access to the bank; and, • Planting of willow stakes is scheduled for November 2007. • Once these IRA activities are complete and closed, AOC-I will be subject to an Activity and Use Limitation (AUL; 310 Ch'1R 40.1074). The goal for this portion of the Site is to close it under a Class A-3 RAO. Small areas at the edge of the existing parking lots and the land within the Valley Home Improvement storage fence still require paving. The necessary prep work for the paving was completed with the bank stabilization and the paving is scheduled for this fall. Once the paving is complete, the chain link fence will be installed at the edge of the pavement and AOC- I of the Site will be ready for an AUL and Class A-3 RAO-P. We anticipate that the bank stabilization NOI Certificate of Completion can be achieved once the willow stakes are installed, and that the IRA Completion Report can be prepared shortly IRA Status Report RTN #I-13320 ~=--°="-Former Cutlery Raceway. October 3, 2007 SCanped "'~~~ ~20-360 Riverside Drive NEE Project No. 02-2053 Page 5 of~6jgj~j~,eC~ --` Northampton, Massachusetts . _~-~=- NEW ENGLAND thereafter. The AUURAO-P can then be finalized and submitted. We anticipate this will occur early in 2008. Erosion had occurred in the sand under the new concrete wall of the sediment trap within the tailrace. The hole under the wall and the flour of the sediment trap were filled with a layer of pea-stone in early June to combat this erosion. This solution did not hold up and the hole under the wall re-formed. It was again filled with large-diameter stone and pea stone over the Summer and the hole formed again. Additional alterations to this sediment trap are scheduled for this Fall. Related Activities in AOC-2 & AOC-3. The following actions remain to be completed for AOC-2 and AOC-3: • Planting of willow stakes is scheduled for November 2007.. • A five-foot high chain-link fence will be erected along the west side of Riverside Drive in AOC-2 & AOC-3 from existing fence to existing fence. The goal of lowering the soil stockpile, adding fencing along the entire length of Riverside Drive in AOC- 2 & AOC-3, and stabilizing the levee bank from erosion is to get this portion of the Site in a condition where it is as stable, controlled and as protected as is feasibly possible at this time in order to qualify for a Class C RAO. This Temporary Solution will allow additional time and research to determine the best long-term approach to remediation of the groundwater and soils, both in place and in the stockpile, in AOC-2 and AOC-3. 2.6 Schedule Cutlery Building Associates plans to have completed the items noted in Section 2.5 above by the due date of the next IRA Status/Completion Report (April 2008). 2.7 IRA Transmittal Form This IRA Status Report has been prepared in accordance with the applicable requirements of the MCP. In accordance with 310 CMR 40.044, an IRA Transmittal Form (BWSC-105) has been completed for the Site. A copy of the form is included in Appendix A. 2.8 Licensed Site Professional (LSP) Evaluation & Opinion A level of "No Significant Risk" has not been achieved. Therefore, additional response actions are necessary before a Response Action t~utcome (RAO) Statement can be prepared. The proposed IRA activities are not complete.

This IRA Status Report covers the period October 20, 2006 through April 20, 2007 at the Site. The objective. of this IRA was to excavate soil that exceeds UCL concentrations for chromium within AOC- I and to move this soil to the. stockpile within AOC-2.

NEW ENGLAND ENVIRONMENTAL, INC. -L I.O INTRODUCTION New England Environmental Inc., (NEE) submitted an IRA Plan dated June 6, 2006 and an IRA Plan Amendment dated August 2, 2006 to gain explicit DEP approval for response actions described in the Revised Phase IV RIP submitted to the DEP on September 15, 2005 for the Former Cutlery Raceway located on Riverside Drive in Northampton, Massachusetts (the Site, Figure I ):.The IRA Plan and IRA Plan Amendment were approved by the DEP in a letter dated August 18, 2006 (Appendix A). This IRA Status Report has been prepared in accordance with the applicable requirements of the MCP. In accordance with 310 CMR 40.0424, an IRA Transmittal Form (BWSC-105) has been completed for the Site. A copy of the form is included in Appendix A. This IRA Status Report covers the period October 20, 2006 through April 20, 2007 at the Site. I . I Description of the Release and Site Conditions The release at this Site can generally be described as disposal of .industrial waste materials, demolition debris,. and common refuse in an unregulated landfill within and along the former raceway leading to the Cutlery Building. The primary contaminants of concern are the metals arsenic, chromium, nickel, sand lead. Other metals, PCBs, and some petroleum products have also been found at the Site above acceptable standards. This IRA specifically addresses the control of metals found within soil and fill materials on the bank of the Mill River west of the Cutlery Building and the former Firehouse within AOC- I and the relocation of these soils to the existing soil stockpile within AOC-2. The area of the IRA is shown in relation to the entire Site in Figure 2. AOC-I Parking_Lots In the Summer of 2005, metals-impacted soil was discovered on the bank of the Mill River behind the Cutlery and Firehouse buildings, west of the parking lots, indicating that AOC-I extends further to the west than previously thought. This meant that simply paving the parking lot surface would not provide a sufficient barrier to isolate this soil. The concentrations of chromium exceed Imminent Hazard (1,000 mg/kg) levels in 9 of the 15 samples collected in this area, and one of these (CB- I at 25,000 mg/kg) exceeds the UCL for chromium (I O;OOOmg/kg). Results of this soil sampling are summarized in Table I. The bank of the Mill River in this location is entirely composed of fill material including a large number of boulders and concrete slabs, and is currently held in place, in part, by the roots of many mature trees. AOC-2 Filled Raceway Soil excavated at the Site in 2004 and 2005 was stockpiled in the central portion of the Site on top~of a filled portion of the former water power raceway (AOC-2). This stockpile was- relatively long, tall, skinny, and was covered with plastic. In total, the stockpile was approximately 180 feet long, 25-30 feet wide and 8-10 feet high with a peaked ridge. A depression in the stockpile near the center provided access to a City of Northampton sewer manhole. 1.2 Previous Related IRA Activities The DEP was notified of the CB-I Irriminent Hazard (IH) condition on July 28, 2005 and an Immediate Response Action (IRA) was initiated. NEE proposed the installation of "No Trespassing" signs as an appropriate mitigating measure under the IRA triggered by the IH condition. The bank of the Mill River where these samples were collected is a deeply wooded area. behind the Cutlery Building parking lot, an IRA Status Report RTN #I-13320 Former Cutlery Raceway April 5, 2007 320-360 Riverside Drive NEE Project No. 02-2053 Page 2 of 5 Northampton, Massachusetts ! NEW ENGLAND area where people do not enter and have no reason to cross. The bank down to the river is quite steep and much of it is simply impassable. The area showed no signs of activity prior to sampling, so posting signs was considered a precautionary measure. Mr. John Bourcier of the DEP agreed that sign posting was an appropriate measure, and the signs were installed the following day, July 29, 2005. In addition to the signs, NEE also installed several short lengths of orange construction fencing in the more accessible areas of the top portion of the bank as an additional deterrent. At a follow-up site visit on August 12, 2005, Mr. Ben Fish of the DEP agreed that the sign posting and fences were adequate mitigation measures for the steep bank. The IRA was closed on September 9, 2005. No other IRA activities have occurred for this condition. As noted in the IRA Plan (NEE June 6, 2006), NEE completed these Phase IV response actions under the IRA provisions of the MCP to assist the City of Northampton planners and Conservation Commission by gaining specific Department approval of the actions prior to their commencement. 1.3 Proposed IRA Activities (as Amended) AOC- I In all areas where exceedance of a. UCL of any metal are identified, this material will be moved to the existing soil stockpile within AOC-2. West of the Cutlery Building and Firehouse, the remaining metals- impacted soil along the bank leading down to the Mill River will be physically stabilized in place and an AUL will be extended from the parking lots down to the river's edge. A chain-link fence will be erected along the west side of the parking lots in AOC- I to restrict access to the bank. Excavated UCL soil from AOC- I will be moved to the existing soil stockpile within AOC-2. Based upon the distribution of sampling locations and laboratory results (CB- I to CB- 15; Table I ), NEE estimates .that less than 30 yd3 of soil exceeding UCL concentrations for chromium will require excavation. The surface of the bank will be stripped of small brush and vegetation, and then covered in a marker layer of bright orange, plastic, construction-type fencing that is laid down around the existing trees. The marker layer will then be covered with four to six inches of cover material and loam, then covered with erosion control landscape fabric, and planted with materials designed to physically stabilize the bank against future erosion, (IRA Plan: Figures 3, 4, and 5). A coconut bio-log will be installed at the toe of the slope within AOC- I to anchor the fabric layers and reduce possible erosion by the Mill River of the lower portions of the new installations. West of the Cutlery Building where the bank is near-vertical, it is unrealistic to assume that even four to six inches of soil will stay on the bank. Some areas of this bank are boulders, and these do not need to be covered with soil and planted. In the remaining areas, soil will be placed between the large rocks and covered with an erosion-control fabric to help hold it in place prior to being planted with materials designed to physically stabilize the bank against future erosion. At the base of established trees, the soil layer will be reduced to nothing so that the trees' root systems and trunks are not suffocated. AOC-2 The stockpile will in turn be lowered slightly, and spread out slightly to remove the high peaks and some of, the steep side slopes. The stockpile will then be covered with a geotextile fabric, loam and seed. The plastic will not be replaced on top of this stockpile. Under the agreement, fabric, loam and seed was considered a better long-term cover material than plastic as it would not degrade in the sun and it _ ...

Percolation of precipitation was not considered a concern as the concentrations of metals in the soil have been demonstrated not to leach in excess of the EPA land treatment concentrations. With the exception of changing the cover material on the stockpile, these actions are similar to those included in the Revised Phase IV RIP submitted to the Department on September 15, 2005. Additional chain link fence will be added to the road-sid.e of. the Site from the southerly chain link fence all the way to the northerly chain link fence; the entire length of AOC-2 and AOC-3: The orange plastic fencing will be moved to the river-side of the soil stockpile, after it has been loamed and seeded. This action will completely encircle the stockpile with fencing. The goal of this IRA Plan remains to remove the most highly contaminated soil from AOC-I and then to stabilize, control and isolate the remaining concentrations, of metals-impacted soil. , Once this is complete, an Activity & Use Limitation will be placed on AOC- I , and NEE will file a Class A3 Partial Response Action Outcome (RAO-P) on this portion of the Site (the Cutlery Building and' Firehouse lots). The remaining Remediation Waste from AOC-I that is included in the soil stockpile located in AOC-2 will be managed as noted below and included in the Class C RAO for those portions of the Site. These actions are sufficient to allow partial closure of AOC- I under 3 I 0 CMR 40.0030. 2.0 COMPLETED IRA ACTIVITIES 2.1 Soil Excavation No soil excavation activities have occurred in the period from October 20, 2006 through April .20, 2007. 2.2 Sign Posting ~ . Additional "No Trespassing".signs were added to both the street and river sides of the Site. There are now six "Posted, No Trespassing" signs along the edge of pavement of the Cutlery and Valley Home Improvement parking lots, a total of I I similar signs on the edge of Riverside Drive along AOC-2 and AOC-3, and three "Posted, No Trespassing" signs along the bottom edge of the levee facing the Mill River in AOC-3, with a final sign at the base of the CB- I excavation facing the River in AOC- I . In all, 12 new signs were added to the Site in September 2006. 2.3 Remaining IRA Activities The following activities remain to be completed within AOC- I at the Site: • The remaining metals-impacted soil along the bank leading down to the Mill River in AOC- I will be physically stabilized in place; • A chain-link fence will be erected along 'the west side of the parking lots in AOC-I to restrict access to the bank; and, • Once these IRA activities are complete and closed, AOC- I will be subject to an Activity and Use Limitation (AUL; 310 CMR 40.1074).

This area is directly downstream from the downstream end of the stone retaining wall that exists along most of the toe of the. slope along the levee, effectively making the stone retaining wall 40-50 feet longer. This new section of stone wall will be up to two feet high. • A chain-link fence will be erected along the west side of Riverside Drive in AOC-2 & AOC-3 from existing fence. to existing fence.. . The goal of lowering the soil stockpile, adding fencing along the entire length of Riverside Drive in AOC- 2 & AOC-3, and stabilizing the levee bank from erosion is to get this portion of the Site in a condition where it is as stable, controlled and protected as is feasibly possible at this time in order to qualify for a Class C RAO. This Temporary Solution will allow additional time and research to determine the best long-term approach to remediation of the groundwater and soils, both in place and in the stockpile, in AOC-3. 2.4 Schedule Cutlery Building Associates plans.to have completed the items noted in Section 2.3 above by the due date of the next IRA Status/Completion Report (October 200. 2.5 IRA Transmittal Form This IRA Status Report has been prepared in accordance with the applicable requirements of the.MCP.

This work is being completed under an IRA which was approved by the Department in June' 2006 and amended in August 2006. Orange plastic fencing has now been installed as a marker layer on the bank surface to identify the former ground surface west. of the parking lots in ACO- I . Spring flooding of the Mill River this Spring caused considerable erosion of the the of the slope in AOC-I and over-topped the silt fence, flattening it in many places. A flexible filter soc filled with seeded mulch was installed along the toe of the slope in this area of the Site as a replacemdnt for the silt fence. Seeded mulch (EcoBlanket?M, see attached product specification sheets) was then sprayed in a layer 2-4 inches thick on the slope on top of the orange plastic fencing in AOC- I . Straw mat was stapled to the top surface of the bank, on top of the EcoBlanketTM, in some of the steeper portions of the. slope to further protect the slope from erosion. The attached photographs show various stages of this installation and the finished installation with . sprouted seed. It is anticipated that some areas will require touch up before the summer is over, and this work is scheduled for August. The bank stabilization plan also called for planting of dormant willow stakes which is scheduled for Novernber 2007. Small areas at the edge of the existing parking lots and the land within the Valley Home Improvement storage fence still require paving. The necessary prep work for the paving was just completed with the bank stabilization and the paving is scheduled for this summer. Once the paving is complete, the chain link fence will b.e installed at the edge of the pavement and AOC-I of the Site will be ready for an AUL and Class A-3 RAO-P. We anticipate that the bank stabilization NOI Certificate of Completion can be achieved once the willow stakes are installed, and that the IRA Completion Report can be prepared shortly thereafter. The AUL/RAO-f~ can then be finalized and submitted. We anticipate this will occur early in 2008.

This would be in place of the five-foot fence outlined in the IRA Plan. They believe a higher fence will be unattractive and very adversely impact ~cannea 9 RE5EARCH DRIVE • A.lvg-~xsT; IVIA. 01002 •PxoNE: • FAx: (413) 256-1092 -- NEW ENGLAND their property value, and is unnecessary as a means of restricting access by the public.. They believe a four-foot fence behind the buildings will be.effective to deter people from climbing over the fence due to the proximity and active use of the buildings. Afive-foot high chain link fence will still be installed along Riverside Drive as originally planned as this area is more accessible to the public. Primarily this is an issue of aesthetic impact of a five~foot fence, and the ability to rent space within the Cutlery Building. The fence will be very close to the buildings and the five-foot height will have• a much more negative impact on the buildings than afour-foot height without any real additional protection of the public. They want to make this minor change to the IRA plans, along the parking lot only, but need assurance from the Department that such a fence will be accepted when this RTN/RAO-P is audited in the future. VVe would appreciate the Department's written response to this request. '~~. Erosion had occurred in the sand under the new concrete wall of the sediment trap within the tailrace. The hole under the wall and the floor of the sediment trap were filled with a layer of pea-stone in early June to combat this erosion, and this solution appears to be holding up. The soil stockpile in AOC-2 has an ample crop of grass and no erosion is apparent on the sides of the stockpile.. This stockpile is solid as evidenced by the lack of evident compaction or erosion when the levee area was accessed for bank stabilization work (see below). The inevitable tire tracks across the top of the. stockpile were seeded with the same EcoBlanketTM mulch material once the levee work was complete, and we anticipate this will look as good as the rest of the stockpile within several weeks. The proposed stone retaining wall at the toe of the slope of the levee in AOC-3 is installed. An eroded, undercut area just above/behind this wall was filled with pea-stone to physically stabilize the bank and return the bank profile to its forrr~er slope.. The entire levee bank was coated in a 2-4" layer of EcoBlanket?M, as was the top surface of the levee. The steepest sections of the .levee bank were .then covered with-straw mat that was stapled to the ground surface in an effort to further combat erosion on the levee bank.
