2. BACKGROUND/RELEASE DESCRIPTION On March 1, 1986, an estimated 2,500 gallons of No. 4 heating oil was released into the basement of the building after a pipe fitting in the heating oil supply system failed. The oil was subsequently discharged into the Boston Inner Harbor by a sump pump in the basement. Clean Harbors Environmental Services, Inc. (CHES) of Kingston, Massachusetts was hired at that time to recover as much oil as possible and to clean the basement, the harbor, and affected shorelines. Figure 2 in Appendix A presents a footprint of the building, the locations of sump pumps and monitoring wells, and an approximate delineation of the site boundary as mapped in July 2007. According to interviews with long‐term employees, the property has experienced groundwater infiltration into the basement during periods of high tides and excessive storm events since at least 1960. During construction of the Central Artery/Third Harbor Tunnel Project immediately west of the Site in the 1990’s, the property owner observed small quantities of oil mixed in with the groundwater that was migrating into the basement. In November 2002, the amount of oil entering the basement appeared to increase, and on November 21, 2002, the then‐owner (Chardon Realty Trust), retained Paragon to perform a site assessment to investigate the possible sources of the oil. Paragon initiated remedial activities and on December 2, 2002, Paragon brought a 20,000‐gallon fractionation tank to the site for oil and water storage generated during dewatering operations. Paragon subsequently installed a 20 gallon per minute (gpm) activated carbon treatment system to treat groundwater from the fractionation tank prior to discharge. Later that month, Paragon installed a recovery sump in the basement of the building for use as an additional oil and water recovery point of collection.

This recovery treatment system operated almost continuously from December 2002 until April 2010, when mechanical problems led to a system shutdown. The system was repaired and began treatment in October 2011.

3. POST‐CLASS C RAO MONITORING OBJECTIVES The global objective of the Post‐Class C Response Action Outcome (RAO) activities is to advance the site toward a Permanent Solution and a Class A RAO. Specific objectives of a system designed to reach a Permanent Solution include:

1. Operate a network of sump pumps to recover groundwater/seawater that infiltrates into the basement area of the building at 160 North Washington Street during periods of high tide. Continuous pumping of sumps during high tide periods is required to control water levels and flooding in the basement;

2. Operate a treatment system for the recovered groundwater/seawater to

remove oil and dissolved constituents prior to effluent discharge to the Boston Inner Harbor;

3. Perform monthly testing of the influent and effluent (following treatment) in

accordance with the permit requirements of the Remediation General Permit applicable to the site;

4. Reduce the level of oil and/or hazardous materials (OHM) in the environment

to levels that achieve or approach background levels.

4. OPERATION, MAINTENANCE & MONITORING ACTIVITIES 4.1 Operations and Maintenance PES Incorporated of Dedham has been retained by the owner to operate and maintain the treatment system. PES’ duties and responsibilities also include regular inspections of the system, an assessment of whether the system is operating properly, identifying any necessary maintenance, and performing said maintenance and upgrades as required. These inspections are currently conducted monthly. PES has also performed inspections of the monitoring wells in the basement of the building to assess the depth of NAPL present in the wells. Not all of the wells are checked on the same schedule, and some of the wells stopped being checked because they have never shown any NAPL. PES did not monitor any of the wells during this reporting period.

4.2 Monitoring and Sampling Activities The start‐up sampling of the influent/effluent was conducted by PES personnel on October 18 & 20, 2011, in accordance with the EPA RGP. One parameter exceeded the RGP effluent limit on day one of system startup according to the results of the sampling;

The effluent pH was 8.4 units, which exceeded the RGP limit of 8.3. PES sent a letter to the EPA notifying the exceedance of pH and Selenium. It should be noted the effluent Selenium on day one of startup sampling was 15.3 ug/L which is below the RGP effluent limit of 71 ug/L. No parameters exceeded the RGP effluent limits on day three of system startup sampling. A summary table of the analytical results and reports is included in Appendix B. The letter to the EPA regarded the exceedances is included as Appendix C. The monthly sampling of the treatment system is schedule to be conducted the week of November 20th and will be included in the next status report. 4.3 System Modifications and Upgrades PES completed repairs and upgrades to bring the system back into operation on October 17, 2011. The following maintenance and repair activities were conducted during this reporting period:

System piping was modified/repaired where necessary;

All four sumps were cleaned out;

All four sump pumps were replaced;

The analog treatment system water meter was replaced;

Installed an isolation valve in line from a groundwater pump where it joins the line from a sump pump;

Installed a new 2” line from the sump pump common receiving line to the carbon filtration system;

Installed of new media in the oil water separator;

Washed out and cleaned the inside of the oil water separator;

Replaced the granular activated carbon (GAC) and sand filters with fresh media.

4.4 WWTP Inspections Cooperstown Environmental LLC conducts wastewater treatment plant (WWTP) operator


Page 7

inspections of the system on a quarterly basis. One inspection was completed during this reporting period on November 16, 2011 following the restart of the system. A copy of the inspection report is included in Appendix D. 4.5 Waste Disposal Wastes generated from the site during the reporting period were removed by Clean Harbors Environmental Services, Inc on October 6, 2011. Waste removed included: media and washwater from the oil‐water separator, spent carbon, sand, and byproducts of sump cleanout. All materials were collected into a pump truck under this manifest. A copy of the manifest is included Appendix E.

5. REGULATORY INTERACTIONS A 5‐year periodic review of the temporary solution was submitted to MassDEP on May 25, 2011. The review discussed the following topics:

Evaluation of the feasibility of a permanent solution

Effectiveness of a temporary solution

Definitive and Enterprising Steps to a permanent solution

Discussion of any changes in exposure

Implementation of an Activity and Use Limitation (AUL)

A copy of the periodic review of the temporary solution is included in Appendix F. No other interactions with regulatory agencies occurred during this time.

6. SYSTEM PERFORMANCE OVERVIEW The system is comprised of four sump pumps located at varying depths below the basement slab. The pumps mitigate the effects of the tidal cycles in the adjoining inner harbor. The groundwater is pumped into a large oil and water separator during high tide; any oil entrained in the influent rises to the top of the tank and is discharged into a holding tank. A transfer pump passes the oil‐water separator discharge through an activated carbon treatment system. The treated water is then discharged back into Boston Harbor. The system is backwashed four times per week on an alternating schedule by two filters. Overall, the system is operating within parameters. PES will continue to monitor the system and make any necessary modifications. A layout of the basement, the treatment system, the groundwater monitoring wells, and the location of the sump pumps is included as Figure 3 in Appendix A.

7. REMEDIAL MONITORING REPORT (RMR) The MCP requires that, for any disposal site where Active Operation and Maintenance of a remedial action is being conducted, a Remedial Monitoring Report shall be submitted in addition to and in conjunction with the submittal of Post‐Class C RAO Status Reports. The RMR must be submitted electronically to the Department on a form established for such purposes. An RMR is being submitted electronically via eDEP concurrently with this submittal. A copy of the Comprehensive Response Action (CRA) Remedial Monitoring Report and the CRA Transmittal Form (BWSC 108 and BWSC 108A/108B) are included prior to submittal on eDEP in Appendix G. The owner has provided Cooperstown Environmental LLC with written authority to make these submittals via eDEP on its behalf as documented in Appendix H.

8. UPCOMING ACTIVITIES PES will continue monthly sampling of the influent and effluent in accordance with the RGP Permit. An analysis will be performed following the system start‐up and an appropriate “shakeout” period, to determine if the site qualifies for Remedy Operating Status (ROS). If so, an ROS submittal will be considered within the next reporting period. Finally, additional recovery wells maybe considered to increase the effectiveness of the system at removing oil beneath the basement.

Periodic Review of Temporary Solut ion160 North Washington Street, Boston, MassachusettsRTN 3-22351

To Whom it May Concern,

The property located at 150 North Washington Street in Boston, MA is covered by the MassachusettsContingency Plan (MCP) and has been assigned Release Transaction Number (RTN) #3-22351. As of 2004, thesite achieved a Class C Response Action Outcome (RAO), which is considered a Temporary Solution. A sitequali f ies for a Class C RAO if i t demonstrates "No Substantial Hazard" but has not yet reached a PermanentSolution. Pursuant to 310 CMR 40.1051(3)b a periodic review of the temporary solution shall be conductedevery f i f th year after the date of the f i l l ing of the Class C RAO. This letter report constitutes the requiredreview for this RTN.

Backoround'^ ̂teose Descriotion

On March I,1986, an estimated 2,500 gallons of No. 4 heating oi l was released into the basement of thebuilding after a pipe f i t t ing in the heating oi l supply system fai led. The oi l was subsequently discharged intothe Boston Inner Harbor by a sump pump in the basement. Clean Harbors Environmental Services, lnc. (CHES)of Kingston, Massachusetts was hired at that t ime to recover as much oi l as possible and to clean thebasement, the harbor, and affected shorel ines.

According to interviews with long-term employees, the property has experienced groundwater inf i l trat ioninto the basement during periods of high t ides and excessive storm events since at least L960. Duringconstruction of the Central Artery/Third Harbor Tunnel Project immediately west of the Site in the 1990's,the property owner observed small quantit ies of oi l mixed in with the groundwater that was migrating intothe basement.

ln November 2002, the amount of oi l entering the basement appeared to increase, and on November 21,2002, the then-owner (Chardon Realty Trust), retained Paragon to perform a site assessment to investigatethe oossible sources of the oi l .

Paragon init iated remedial activit ies and on December 2,2002, Paragon brought a 20,000-gallonfractionation tank to the site for oi l and water storage generated during dewatering operations. Paragonsubsequently instal led a 20 gallon per minute (gpm) activated carbon treatment system to treat groundwater

from the fractionation tank prior to discharge. Later that month, Paragon instal led a recovery sump in thebasement of the building for use as an addit ional oi l and water recovery point of col lection.

This recovery treatment system operated almost continuously from December 2002 unti l Apri l 2010, whenmechanical problems led to a system shutdown. Technical and other issues have prevented a suitable restart

These repairs are nearly complete and the

Permanent Solution Feasibilitv Evaluation

In accordance with Section 310 CMR 40.1051(3)b(1), this section addresses the feasibi l i ty of implementingone or more Permanent Solutions for the disposal site.

ExcavationExcavation is a proven and dependable approach to remove contaminated soil . This approach entai ls thegross removal of impacted soil and subsequent post-excavation sampling and laboratory analysis, fol lowed bythe restoration of the site upon completion of the excavation. Contaminated soilwould be excavated in thevicinity of the closed-in-place tanks beneath the building. Excavated soil may be treated above ground,removed from the site for off-site treatment or recycling, or sent off-site for landfill disposal.

Pros:. Short implementation t ime frame. Dependable and assured removal of substantial ly al l contamination from the site

Cons:. High implementation costs for removal, treatment, transport and disposal. Would require the removal of overlying building and/or basement slab. Would require control of groundwater during excavation

This approach currently is neither feasible nor practical for implementation at the site for numerous reasons.Excavation of soi l underneath the building would require the removal of the f ive-to-six foot thick concreteslab, which would not only be cost prohibit ive, but could also undermine the structural integrity of thebuilding. Furthermore, the soil beneath the slab is below mean sea levelso signif icant controlof thegroundwater and the t ides would be required during this work. Therefore, this option for obtaining apermanent solution is infeasible from both a cost and technical standpoint.

Monitored Natural AttenuationMonitored natural attenuation (MNA) depends on a variety of natural processes including biodegradation,dispersion, sorption, volati l ization, di lut ion, and stabil ization, transformation, or destruction of contaminantsover t ime to result in a reduction of groundwater concentrations to acceptable levels. This process, whichoccurs to some degree at most sites, is monitored to ensure that condit ions are appropriate at the site toresult in the reduction of contaminant levels to objectives within a regulatory-acceptable t imeframe.

Pros:. Low tech approach avoids capital costs. Can operate over a period of years with a relatively low degree of oversight. Can operate in conjunction with exist ing NAPL and groundwater recovery and treatment system. Avoids exposure to subsurface contaminants, thereby reducing risks

Cons:. May not be applicable where NAPL exists due to slow or non-existent degradation rates. Can require extended t ime to reach an acceptable endpoint, result ing in a lack of applicabil i ty

We believe that this approach is not a feasible approach at this site to reach a Permanent Solution within areasonable t ime frame, because of the presence of NAPL.

Five Year Periodic Reviewl-60 North Washington - Boston, MARTN 3-223s1Page 3 of 4

Separate - Phase Product RecovervThis approach is currently in use at the site. l t entai ls the use of four sump pumps located in sumps in thebuilding basement. The sumps recover groundwater/sea water that inf i l trates into the building during hightide. The water is then pumped through a treatment system before being discharged to the harbor.

Pros:. Controlthe migration of the oi l and petroleum-impacted groundwater at the source area and off

the siteCons:

O&M costs for system operat ion and monitor ing are ongoingVery long t ime for complete cleanup due to relat ively low solubi l i ty of contaminants anddif f icul ty of mobi l iz ing viscous oi l out of the soi l matr ix

This approach is currently being used at the site and has achieved l imited success at removing contamination.We do not believe that pump and treat is a feasible approach to developing a Permanent Solution currentlybut could be successful over t ime.

Effe ctive n ess of Tem po ra rv Sol utio n

In accordance with Section 310 CMR 40.1051(3)b(2) an evaluation of the effectiveness of the TemporarySolution is required.

The current temporary solution is a treatment system comprised of sump pumps in the building basementthat operate during periods of high t ide to maintain the t idal ly-inf luenced groundwater below the elevationo f thebasemen t f l oo r . Thesumppumpsarea lso inopera t i on to removeNAPLtha thasbeen iden t i f i edbeneath the basement f loor and which enters the sumps along with the t idal ly-inf luenced groundwater. Thegroundwater is treated via an oi l-water separator, sand f i l ters, and a Granular Activated Carbon (GAC) systemprior to discharge into Boston Harbor. ln general, the system appears to be meeting the l imited goals ofpreventing f looding of the basement during periods of high t ides while also preventing the discharge of oi lywater into the harbor. Overal l the system recovers a relatively small amount of oi l but has been successful inpreventing the oi l from entering the basement. l t should be noted that the treatment system has been shutdown for a substantial t ime due to mechanical and other issues. l t is currently undergoing repairs and isexpected to be back in operation within weeks.

Definitive and Enterprisina Steps to o Permanent Solution

In accordance with Section 310 CMR 40.1051(3)b(3)the review must discuss the definit ive and/ orenterprising steps taken to identify, develop and implement a feasible solution at the site.

A separate-phase product recovery and treatment system was identif ied in the Phase l l l Assessment as themost cost-effective route to achieve a permanent solution. The system has not been completely effective atremoving oi l beneath the basement, and an evaluation of system effectiveness is currently on-going andconsiderations include the instal lat ion of addit ional recovery wells.

In addit ion to the recovery and treatment system, the planned instal lat ion of a sea wall along the interfacebetween 160 North Washington St. bui lding and Boston Harbor is expected to commence in the near future.The sea wall is an integral step in ult imately attaining a Permanent Solution for this site. Under currentcondit ions, a potential migration pathway exists between the residual petroleum that has been identif ied

Five Year Periodic Review1-60 North Washington - Boston, MARTN 3-22351Page 4 of 4

[$o"NVIRONMENTATS

below the bui lding foundat ion and Boston Harbor. Instal lat ion of the sea wal l wi l l ef fect ively serve as abarr ier that prevents the residual petroleum const i tuents from escaping into the Harbor.

Chanaes in Exposures

Sect ion 310 CMR 40.1051(3)b(4) requires a discussion of any changes in act iv i t ies, uses, and/or exposure forhuman or environmental receptors to oi l and/or hazardous mater ials.

The bui lding is current ly unoccupied and only maintenance workers are present at the si te on occasion. Theimpacted soi l and groundwater (NAPL) is located beneath the slab of the bui lding, and therefore humanexposure is l imited even when workers are present. The NAPL does intrude into the basement, however, andso i t does present a possibi l i ty for exposure to humans in that case.

Future plans areto redevelopthe property. As partof that project, a seawal lwi l lbe implemented, hopeful lyreducing or prevent ing t idal inf luence on the groundwater and thus el iminat ing the twice-dai ly inf i l t rat ion ofgroundwater into the basement.

lmplementation of dn Activitv and Use Limitation (AULI

There is not an AUL on the si te. Due to the unl ikel ihood of accessing and removing al l of the contaminat ion,an Act iv i ty and Use Limitat ion wi l l most l ikely need to be included in any permanent solut ion. In addit ion, apermanent solut ion would need to demonstrate that NAPL exists " in any environmental medium" at athickness of less than one-half inch. Measurements over the past several years indicate that such a condit ionmay be in place.
