Update

After more than a year of submittals,reviews and a public hearing, final per-mits to allow the start of remediation ofthe UConn landfill and former chemicalpits were issued by the Army Corps ofEngineers (ACOE) and the ConnecticutDepartment of Environmental Protection(DEP) in July 2005. The ACOE permitincludes conditions set by DEP and spe-cial provisions to protect wetlands andmigratory species in the area during con-

struction. UConn submitted several indi-vidual permit applications to DEP’sWater Management and Inland WaterResources Division, and ACOE requireda Wetland Mitigation Plan to address tem-porary and permanent impacts in thearea.

Securing the permits marks an impor-tant stage in the remediation project.After more than five years of planning,investigation and review, construction of

Landfill Remediation Project

With permits in place and a Construction Manager chosen, constructionactivities to remediate and close the landfill and former chemical pits willbegin in late 2005 and early 2006. The article below describes the key permitsand conditions UConn will comply with to complete the project. The permitsinclude such re q u i rements as time limits on construction and special pro t e c t i o nfor wetland areas. Copies of the permits are available at the Mansfield PublicLibrary and at UConn Communications.

After a review of proposals from interested Construction Managementfirms, O&G Industries of Torrington, CT, was awarded a ConstructionManager contract for the project based on its experience and fees. O&G isproviding a guaranteed maximum price for the work and it is reviewing bidsfor the pro j e c t ’s specialty contracting trades. These include site work, mechanicaland electrical trade contractors and companies experienced in excavation,landfill compaction, constructing interceptor trenches and working withgeomembranes and gas collection systems, as well as elements of the landfillcover. Wetland restoration and landscaping complete the construction tasks.The article on page 3 describes the initial construction activities.

While the landfill investigation and permitting were underway over thelast six years, residential domestic wells near the project study area were thefocus of the Interim Monitoring Plan (IMP). The IMP also included sampling of groundwater and surface water locations in the study area andaround its perimeter. The IMP was designed to evaluate groundwater qualityobtained from drinking water wells located near the landfill and former chemical pits until the Remedial Action Plan was implemented. The articleon page 5 describes the transition from the IMP to the Long-TermMonitoring Plan (LTMP).

INTRODUCTION

UConn Secures State and Federal Permitsfor Landfill Remediation and Construction

W H AT IS THE UCONNLANDFILL PROJECT?On June 26, 1998 theDepartment of EnvironmentalProtection issued a ConsentOrder to the University ofConnecticut. The order requiresUConn to thoroughly evaluatethe nature and extent of soil,surface water and groundwaterpollution emanating from theUniversity landfill, former chemi-cal pits and an ash disposal siteknown as F Lot. The order alsorequires UConn to propose andimplement remedial actions nec-essary to abate the pollution.The UConn Landfill RemediationProject is the process thatUConn is undertaking to complywith the order.

the site remedy can begin. The landfillproject was undertaken to comply with aConsent Order with DEP that lays out thegoals for the remediation. The processprovided for a Technical ReviewCommittee, which developed the investi-gation protocols and reviewed all of thetechnical information, and a publicinvolvement program, which reached outto interested and affected parties, includ-ing the Town of Mansfield, community

and student groups and abutters to thestudy area. After DEP approved theremediation plan in November 2004, thepermits were the subject of a public hear-ing in January 2005.

Permit Background The Remedial Action Plan (RAP) out-lined the permits required for construc-tion. After the RAP’s approval, UConnand its consultants began submitting thepermit applications needed to begin con-struction to DEP and ACOE. The reme-diation activities in the study area willaffect wetlands near the landfill and for-mer chemicals pits, and these areas willrequire erosion protection and other siteconsiderations.

DEP and ACOE have responsibilitiesfor different aspects of the project. TheCorps required a Section 404 IndividualPermit. DEP had jurisdiction over theother permits, including: an InlandWetlands and Watercourses Permit and401 Water Quality Certificate; a FloodManagement Certification; general per-mits for Discharge of GroundwaterRemediation Wastewater to a SanitarySewer; a General Permit for Discharge ofStormwater and DewateringWastewaters from ConstructionActivities; and a Combined Permit forDisruption of a Solid Waste ClosureArea, Landfill Closure and Post-ClosureUse. The October 2004 Update containsdetailed information about the permitapplications (it is available athttp://landfillproject.uconn.edu/files/updates.html).

Wetland MitigationAfter initial reviews of the application,ACOE asked UConn to prepare a WetlandMitigation Plan because of the impact ofconstruction on wetlands in the area.The wetlands are affected since they con-

(that is, wetlands that UConn’s contrac-tors will disturb, but ultimately restore),no excavation or fill placement will takeplace during this season. Routine erosionand sedimentation controls will continueto be maintained during this time to pro-tect these wetlands from work in abut-ting areas. In addition, in wetlandrestoration and creation areas, limitedspring planting will also take place, suchas seeding and hand planting.

General ACOE ConditionsIn addition to the Wetland MitigationPlan, the Army Corps permit (NAE-2004-661) lays out other specific conditions.The entire permit must be included in theconstruction bidding specifications andposted on the site. UConn must notifyACOE two weeks before the mitigationwork begins and submit a number ofrequired forms. In addition, UConn mustexecute and record a conservation ease-ment for an area designated as OpenSpace, protecting it in perpetuity. TheACOE permit includes DEP’s permit con-ditions by reference.

DEP Permit Conditions DEP has jurisdiction over a number ofthe construction and remediation activi-ties at the landfill and former chemicalpits. As a result, DEP’s permits include avariety of conditions from startup to con-struction practices to project completionand site monitoring. (See the box belowlisting a number of key conditions.)

The permit conditions are to ensurethat the work meets the goals and stan-dards of the remediation plan, is com-pleted in a timely fashion and does notunduly disrupt neighboring areas orresult in changes that are not approvedby DEP. UConn will submit monthlyconstruction summary reports to theCommissioner. Any changes proposedfor the Wetland Mitigation Plan must be

tain contaminated sediments that will beremoved during the construction project.Construction will have the positive effectof eliminating future discharge of con-taminants, but it will also disturb the sur-rounding wetlands.

The Wetland Mitigation Plan has threecomponents: • Restoration - measures to be taken in

wetland areas that will be disturbed, but not lost

• Wetlands creation – constructing new wetlands to compensate for wetlands that will be lost due to the re m e d i a t i o n

• Wetlands enhancement – improving existing wetlands and habitats that will be disturbed, then restored, by removing waste, fill materials and debris currently in those areas

The landfill closure will result in the lossof 1.83 acres due to filling and post-clo-sure uses. Another 2.97 acres of wetlandwill be temporarily disturbed by theremoval of contaminated sediments andfill. In addition to restoring the wet-lands, UConn will enhance 12.4 acres ofwetlands and preserve another 27 acresof wetland and 33 acres of forestedupland. The plan also includes control-ling invasive species and exotic plantspecies that can clog and endanger thewetlands.

After reviewing the mitigation plan,ACOE asked UConn to comply with aspecial condition to protect amphibians,such as salamanders, wood frogs andtoads, in the wetlands. These amphib-ians lay their eggs in vernal pools thatappear only seasonally. No work willtake place in the vernal pool areas andlimited work will be conducted in sur-rounding wetland areas during themigratory and reproductive times forthese species, which occur betweenMarch and May. In wetlands that willremain once the project is completed

Creating a New Wetland

When the landfill construction is completed, neighbors, facultyand students will discover an added benefit: a new, 60-acreopen space conservation area north of the landfill. Wetlandsthat are currently affected by sediments and leachate will berestored and re-established. A mixture of clean granular soils,derived primarily from the wetland creation areas, and organicsoils – recycled from excavated soils removed from the BurtonFootball complex area – will replace contaminated sediments orwaste. New wetlands will be created, planted with native veg-etation and monitored for invasive species. These areas will beinspected monthly for a period of 10 years to make sure plantsare thriving, soils are wet, permit limits are being met, wildlifeare thriving and invasive species are controlled or removed.

Over time, the new wetland areas will serve as a home to localwildlife, including turkeys, beaver, deer and other small mam-mals. These wetlands offer UConn and the community thechance to observe wildlife, study the function of wetlands andconduct research on invasive species. These wetlands will also serve as alaboratory for Connecticut’s invasive species research program, which islocated in Storrs, and as a home to a diversity of species.

When construction begins early this win-ter, contractors will take the first steps ina year-long project to close the landfilland former chemical pits according to theplan approved by the ConnecticutDepartment of Environmental Protection(DEP). Site preparation and mobilizationwill be the first visible steps. With a roadin place and equipment on site, excava-tion, dewatering and consolidation ofapproximately 28,000 cubic yards ofwaste and sediments will begin. Therewill be some inconvenience – such asshort-term closing of the pathway fromCeleron Square to the Motor Pool – butsafety and permit compliance are impor-tant aspects of the project. O&GIndustries, the Construction Manager(CM), will oversee permit complianceand respond to issues that arise duringconstruction. Quarterly well samplingand reporting will continue during thistime.

Getting Started The first challenge of construction is toreach the landfill site. Initially, the sitepreparation contractor will bring equip-ment in from North Hillside Drive andthrough the UConn Motor Pool area. Atthe southern end of the landfill, the CMand contractors will set up an area forconstruction trailers, equipment storageand laydown. This fenced area will be inthe vicinity of the current transfer station.This process should take about two tothree weeks.

UCONN PREPARES FOR LANDFILL C O N S T R U C T I O NWith equipment on hand, the site

preparation contractor will construct aroad at the southeast end of the landfillconnecting the construction area directlyto North Hillside Drive. Completion ofthis road will take truck traffic awayfrom UConn’s busy equipment storageand repair area. Road construction isexpected to take a month.

Before the contractor begins the nextstep – moving waste and soil – the sitepermit requirements have to be met,including establishing erosion controls,which will include hay bales, silt fences,and filter berms designed to protect wet-lands and surface waters from runoff ofsilt from the work areas.

Waste relocation is the first remedia-tion task. The landfill is roughly an ovalmound oriented northwest to southeast.The sides slope away from the moundand are known – at the edges – as the toeof the landfill. There are wetlands to thenorth and south, which will be affectedby construction to remove contaminatedsediments.

During the landfill investigation,waste was found outside the toe of thelandfill in several places. The RemedialAction Plan (RAP) requires the contrac-tor to excavate this material and place iton top of the landfill before the cover isconstructed. This outlying waste will beconsolidated beneath the landfill cover,which will contain and prevent it fromleaching into groundwater.

Most of this excavated waste will endup on the western flank of the landfill. Ifthe material is very wet, it must be driedout first, a process known as dewatering.This can be done by placing it within anearthen dike on top of the landfill or mix-ing the materials with dry soil beforeplacing it on the landfill. Once thewaste/soil mix is dry, a ride-on, doubledrum vibrating sheep’s foot roller rollsover the materials. Resembling a frontend loader, the roller has steel wheelswith knobby extensions. It rolls over thewaste, compacting and flattening it.

At the end of each work day, wasteexposed by this operation will be coveredwith soil or a cover of some type. Thenext day, it will be uncovered and theprocess will be repeated. The coverkeeps the material in place and preventsit from being disturbed by weather oranimals. It also contains odor that mayemanate from the disturbed earth.

The process of waste consolidationwill take about two to three months.During this time, neighbors may hear thebackup beepers from the constructionequipment in the distance, and, when thetrees are bare, see the earth movers andcompacters at work.

Safety concerns will also require occa-sional closing of the pathway. Based oncurrent understanding of the work plan,the path will be closed as construction isclose to sections of the walkway.

Sediments will be removed from the south wetland, requiring restora-tion of about a third of an acre.

CM must keep an inspection log and takeappropriate action to correct any defi-ciencies. Periodic agency inspections arelikely.

With site controls in place, the con-tractor will remove any visible surfacewaste for compaction on the landfill.The next step will be undertaking sedi-ment removal. This aspect of construc-tion will have the greatest impact on thewetlands. Project engineers and scien-tists believe that the contractor will haveto remove about two feet of sediment.This includes scraping through the vege-tation in the area, a process that will alterthe appearance of the wetland.

The contractor will deposit the sedi-ments for drying and compacting on thelandfill. During this time, sampling inthe wetland will be required to deter-mine how wide and deep the sedimentremoval needs to be. The contractor willremove vegetation and sediments, sam-ple to the sides and below, then continuewith the removal until sampling con-firms that the area is free of landfill orchemical pits contaminants.

The northern wetland is a wet one: inthe spring, there may be one or two feetof water present. The contractor will cre-ate a gravel filter berm or dike so waterthat gets stirred up stays within thebermed area during this process. To thesouth, the wooded wetland can be con-tained with more traditional means.

Like the waste, the wet sediments willbe dried in a diked or bermed area atopthe landfill. They can also be mixed withdrier soil or be turned and tilled to airdry. They will be compacted on the land-fill.

Permit conditions limit the timing ofwork in the wetlands. Work in restora-tion areas cannot take place betweenMarch and May, when it could impactmigration and reproduction of certainspecies. It is actually easier to work withpartly frozen earth, so the contractor islikely to try to complete this work duringthe winter.

While the construction documentscontain limits due to permit requirementsand other regulations, the contractors areallowed flexibility in other areas. Oncethe final contractors have been chosenand their schedules are approved, morespecific information will be shared withthe community in an upcoming Update.

Short-Term EffectsUntil the wetland restoration takes place,the excavated areas will appear raw andbarren. Restoration is a condition of theremediation. It is described in detail inthe October 2004 Update, which is avail-able at http://landfillproject.uconn.edu/files/updates.html. The WetlandMitigation Plan includes wetlands cre-ation, enhancement and restoration. Theconstruction will result in the loss of 1.83acres of wetland due to filling and post-closure use. Another 2.97 acres will bedisturbed by the removal of contami-nants and fill. These acres will beaddressed by the mitigation activities. Inaddition, UConn will enhance or improve12.4 acres of wetlands and preserve 60acres, including 27 acres of wetlands and33 acres of upland.

Remediation of the wetland to the south(see below) involves construction close toor on the path. When this work is com-plete, jersey barriers and other protectionwill be put in place to allow the bicycleand walking path to remain open duringnon-construction hours.

Next StepsDuring this consolidation process, thecontractor will also pull waste back fromthe edges of the landfill to constructleachate interceptor trenches, or LITs.Leachate is any liquid that passesthrough solid waste and contains sus-pended or soluble materials in solutionthat came from the waste. Currently,leachate from the landfill affects thequality of groundwater and surfacewater to the north and south of the land-fill. It also appears in wetlands to thenorth and in the upstream segment ofone stream.

The contractor will construct trencheson the north and south toes of the land-fill, to intercept and collect leachate andgroundwater that flow from the site. Theflow will be collected in gravel-filledtrenches which will contain a set ofextraction wells. The leachate will bepumped from the wells to UConn’swastewater treatment plant. Wetlandsexcavation will take place next. First,erosion and sediment controls – siltfences and straw bales – are put aroundthe area to prevent or capture runofffrom sediments. The project permitrequires the CM to inspect these meas-ures after every significant rainfall. The

Closing the Pathway

The pathway from Celeron Square along the edge of the landfill to theMotor Pool is a popular route to campus for walkers and bicyclists.Because it parallels and crosses the construction area, the ConstructionManager, O&G Industries, anticipates that the path will have to be closedfor short periods of time beginning in January 2006. Jersey barriers andtemporary construction fencing will be used to keep people away from thework site. Because of the intense construction activity and movement ofmaterials, the path will be closed off during the day from time to time.UConn regrets the inconvenience, but the safety of students, faculty andresidents makes it necessary.

Updates on the schedule for the bike path closure will be posted atwww.landfillproject.uconn.edu.

The path linking Celeron Square and the UConn campus will close temporarily because it is too close tointense construction activity.

is in place. The LTMP will also protect human health and theenvironment by evaluating the samples of groundwater andsurface water against Connecticut’s numerical remediation stan-dard regulations criteria (RSRs) over time.

The IMP sampling program currently includes nine activedomestic wells on Meadowood Road, Separatist Road,Hillyndale Road, Hunting Lodge Road and Northwood Road.The wells in the LTMP program were chosen by DEP in consul-tation with the other parties. The long-term program includessix active wells on Meadowood and Separatist Roads and twoinactive wells on North Eagleville Road and Hunting LodgeRoad (the wells are not in use because the owners are connectedto UConn’s water supply).

Representing UConn, Haley & Aldrich, Inc., will collect quar-terly samples from the private wells serving these residences.Samples will be analyzed for volatile organic compounds(VOCs), metals, inorganic parameters (such as alkalinity, hard-ness and sulfates) and field screening data (temperature, pH) bya State-certified laboratory. UConn will continue to evaluate theresults in conjunction with DEP, DPH, and the EasternHighlands Health District and provide copies to homeowners.

Over the course of the investigation, UConn connected sever-al homeowners around the perimeter of the study area to itswater system. The state drinking water protection criteria wereexceeded for benzene at one home, and trace amounts of sol-vents (trichloroethene and tetrachloroethene) were detected attwo homes. Those homes were promptly connected to UConnwater. Other connections, along the perimeter of the study area,were chosen by DEP to provide an added level of protection tothese residences.

The LTMP also includes quarterly monitoring of groundwa-ter, soil gas, and surface water near the landfill and formerchemical pits. Data collected from these monitoring locationswill be evaluated to track the effectiveness of the removal ofcontaminated sediments and soils, the capping of the landfilland former chemical pits, and the collection of landfill leachate.

Over the last six years, UConn has conducted quarterly sam-pling of groundwater, surface water and domestic wells aroundthe landfill and former chemical pits study area. The InterimMonitoring Program (IMP) was developed to monitor activeresidential water supply wells during the hydrogeologic investi-gation of the landfill study area. With the onset of constructionto close the landfill, UConn will be moving from the IMP to aLong-Term Monitoring Plan (LTMP). A transition period beganin August 2005 and will continue through December 2005.While the IMP continues during the last quarter of the year, thefirst round of sampling for the long-term plan will begin.Overlapping sampling will provide continuity and protecthuman health and the environment. The LTMP will continuefor thirty years.

The IMP has been in place through the five-year landfillinvestigation period. To date, 18 IMP sampling rounds havebeen completed. More than 390 groundwater samples and morethan 80 surface water samples were collected for chemicalanalysis. The results of the sampling are reported to homeown-ers, the Town of Mansfield, Eastern Highlands Health District,the Connecticut Department of Public Health (DPH), and theConnecticut Department of Environmental Protection (DEP).Over the life of the IMP, DEP, DPH, the U.S. EnvironmentalProtection Agency (EPA), consultants for the Town of Mansfield,the Eastern Highlands Health District and UConn’s consultantsreviewed the sampling data. The IMP samples are submitted toa private, state-certified laboratory for analysis.
