SECTION 1 INTRODUCTION

The Motor Wheel Disposal Site Group has contracted with Sharp and Associates, Inc. (SHARP) andHWH Engineers (HWH) to prepare the Draft Final Design for the Motor Wheel Disposal Site(MWDS). This design is for the landfill cap and for the groundwater remediation system that addressesthe glacial aquifer plume and the potential flows from the Saginaw aquifer plume. These systems arebeing designed in order to comply with the Record of Decision (ROD) (September, 1991) and theRemedial Design Consent Order, and accompanying statement of work.

1.1 GENERAL BACKGROUND AND SITE HISTORY

The MWDS is a 24-acre property located at 1401 Lake Lansing Road on the northeast edge of the Cityof Lansing, Michigan. The site lies in the NE 1/4 of the SW 1/4 of Section 3 in Lansing Township(T4N, R2W), Ingham County, Michigan (Figure 1-1, page 2). The MWDS and surrounding propertiesare illustrated in Figure 1-2 (page 3). The property was used by Motor Wheel Corporation as adisposal site for industrial wastes from 1938 until about 1978 (US EPA, 1991). The types of disposedwastes included solid and liquid industrial wastes, such as paints, solvents, liquid acids, caustics, andsludges. Wastes were disposed of on the property in tanks, barrels, seepage ponds, and open filloperations (US EPA, 1991).

Between 1970 and 1982, at least three cleanup actions were initiated, which resulted in the excavationand off-site disposal of waste materials (Hunter/Keck Environmental Services [Hunter/Keck], 1990).In 1970, the Michigan Department of Natural Resources (MDNR) requested that the Motor WheelCorporation remove solid wastes, paint sludges, and oils from seepage pond areas for disposal off-site.Some of the excavated materials were disposed off-site and the former pond areas were backfilled (USEPA, 1991). Three 10,000-gallon tanks, their contents and contaminated soil, and fill surrounding thetanks were removed and disposed off-site in December, 1982. An unknown number of drums werealso disposed of off-site at this time (US EPA, 1991).

In 1978, MSV Associates acquired the property and began open-pit sand and gravel mining. Themining operations exposed some of the buried industrial wastes. The exposed materials weresubsequently excavated, stockpiled on the western part of the site, and covered with clay (US EPA,1991).

The site was placed on the National Priorities List on October 4, 1986 (50 FR 41015). On June 26,1987, Motor Wheel Corporation, W.R. Grace & Co. (Grace), and The Goodyear Tire & RubberCompany (Goodyear) signed an AOC agreeing to conduct a Remedial Investigation (RI) and FeasibilityStudy (FS) at the MWDS (US EPA, 1991). Following USEPA's ROD in September, 1991, Goodyear,Grace, Textron, Inc., and the Lansing Board of Water and Light entered into a consent agreement toconduct the Remedial Design.

Site gravel/sand mining operations were discontinued in 1987. MSV Associates is the current owner ofthe property. The site is presently inactive (US EPA, 1991).

1.2 PREVIOUS STUDIES

In accordance with the AOC, an RI for the site was conducted by Hunter/Keck. The results of the RIwere summarized in a report dated February 8, 1990, and titled, Remedial Investigation Report, MotorWheel Disposal Site, Lansing, Michigan. An FS was conducted by ENSR Consulting and Engineering(ENSR). The results of this study were summarized in a report titled, Final Draft Feasibility StudyReport for Motor Wheel Disposal Site, dated May, 1991. The Declaration for the Record of Decision(ROD) was signed by the US EPA on September 30, 1991. An investigation of the Saginaw aquifer atthe MWDS was conducted by ENSR, and the results summarized in a report titled, Saginaw AquiferInvestigation for the Motor Wheel Disposal Site, Lansing, Michigan, Consultants Report, dated April,1992, Document No. 3144-02-574. Another investigation of the Saginaw aquifer at the MWDS wasconducted by Fishbeck, Thompson, Carr and Huber (FTC&H), and the results summarized in a reporttitled, Saginaw Aquifer Investigation Report for Motor Wheel Disposal Site, Lansing, Michigan,Consultants Report, dated March 1995. Additional investigations were performed and a Predesign wasdeveloped by FTC&H. These activities are summarized in Final Additional Studies/Predesign Report,1996.

1.3 RECORD OF DECISION

The ROD for the first operable unit at the MWDS was signed on September 30, 1991. The firstoperable unit included the waste mass and the groundwater contamination in the perched and glacialaquifers at the MWDS. The groundwater contaminants of concern, as determined by the RI, and therisk and toxicity assessments, included the volatile organic compounds (VOCs):

1,1 -Dichloroethene (1,1 -DCE) Chloromethane1,2-Dichloroethane (1,2-DCA) Ethylbenzene1,2-Dichloroethene (1,2-DCE) Methylene Chloride2-Butanone Naphthalene2-Hexanone Tetrachloroethene (PCE)4-Methyl-2-pentanone Trichloroethene (TCE)Benzene TolueneChloroethane Vinyl Chloride (VC)Choroform Xylenes, Total

The semivolatile organic compound (SVOC) contaminants of concern included bis(2-ethylhexyOphthalate and 2,4,5-trichlorophenol, and the inorganic contaminants of concern includedammonia nitrogen, chloride, fluoride, iron, lead, nitrate, sulfate, and zinc.

The ROD cleanup criteria for the respective constituents are presented in Table 1-1 (page 5). In June1995, Michigan amended the Michigan Environmental Response Act, Act No. 307 of 1982 andincorporated the amended act into the Natural Resources and Environmental Protection Act, Act No.451 of 1994. This new legislation included changes in the cleanup standards that were previously citedas Applicable or Relevant and Appropriate Requirements (ARARs) in the ROD.

Final Design ReportMotor Wheel Disposal SiteSharp and Associates. Inc95rpt.doc/rev. 4/30/97

The major elements of the remedial alternative selected in the ROD include:

• Installation of an engineered landfill cover system over the disposal area.

• Backfilling to cover exposed fill areas and to establish an acceptable slope in the excavatedarea of the site, for extension of the cover system.

• Extraction of contaminated groundwater from the perched zone and the glacial aquifer, andtreatment of the groundwater by air stripping.

• Site deed restrictions to limit development and land use, and to prevent installation ofdrinking water wells or other intrusive activities at the site.

SECTION 2 LANDFILL CAP

2.1 LANDFILL CAP DESCRIPTION

An engineered cap and landfill cover system will be installed to provide a low-permeability, highevapotranspiration, barrier to the subsurface materials. The cap and cover system will encompassapproximately 13 acres, as shown the construction drawings (in Appendix E).

In deriving the conceptual cap design included in this submirtal, the boring logs used originally toestimate the areal extent of the waste boundary were revisited because the waste boundary appeared tocontradict strong topographical clues as to the historic manipulation of subsurface materials. A smallarea at the extreme southern edge of the estimated waste extent was also reevaluated. All examinedboring logs and a site map showing their location are included in Appendix F.

Specifically, boring logs LC-11 through 16 and LC-42 were looked at in the western portions of thelandfill, near the railroad tracks. The logs of LC-13, 16 and 42 showed no indications of any wastematerial, or the types of assumed waste materials identified in other borings, previously interpreted tobe indicative of landfilling, yet the previous extent of waste estimate either included these borings, orwas bordered by one or more of these borings. The assumed waste materials identified in theremaining borings include a 0.2 foot layer of brick fragments included in a silty sand in LC-14, a 2.1foot layer of cinders and gravel mixed with a silty sand from LC-11, and occasional coal fragmentsbetween 5 and 9 feet deep in LC-12. These materials, at these depths, located in and around anabandoned railroad track, are not necessarily indicative of historic landfilling, but may find their originin the types of material used to construct the railroad embankment itself, and/or a possible result ofrailroad operations. This hypothesis is further supported by the fact that the readjusted extent of wastein this area better coincides with the toe of the slope extending from the landfill property, and the legalboundary of the landfill property itself.

Similarly, the boring logs for MW13D, MW24, and LC-65 were evaluated, along the extreme southerntip of the waste area. The logs for the two monitoring wells indicated no waste materials, yet theselocations were shown well within the extent of waste. A fill/slag mixture included in a silty sand wasidentified up to the 4.5 foot depth in LC-65. The extent of waste was reinterpreted to exclude thesethree borings.

The net effect of the reinterpretation of the extent of waste is to decrease its total area by approximately2/3 of an acre.

The final cap configuration has been derived through careful consideration of the following designfactors:

• 3 % minimum cover slope;• 25% maximum cover slope;• minimization of waste excavation;• minimization of import of fill material; and• maximization of runoff to the gravel pit remnants.

Final Design ReportMotor Wheel Disposal SiteSharp and Associates. Inc95rpt.doc/rev. 4/30/97

2.1.1 Cap System Components

The overall strategy of the landfill cap and cover system is to reduce vertical migration of water intosubsurface materials. The cap and cover system will be comprised of multiple components, including:

• Lower unclassified fill layer;• Clay mineral resource barrier layer;• Drainage layer;• Geotextile;• Upper unclassified fill layer;• Topsoil layer;• Vegetation;• Storm water diversion;• Soil erosion control; and• Gas venting.

The following section provides a description of each cap component as well as the basis for its design.This information is communicated in detail in the construction drawings. Technical Specifications, andConstruction Quality Control Plan.

Lower Unclassified Fill Layer Unclassified mineral fill will be used to achieve the grades necessary toachieve proper site drainage and slope stability. The thickness of this layer will range from 0 to 5 feet.

Clay Barrier A minimum of three feet of compacted clayey soils will be placed over the subsurfacematerials. Clayey soils shall consist of material classified as CL or CH under the United SoilsClassification System (USCS) and, when compacted in-place on the landfill to 95% of the MaximumStandard Proctor Density, shall have a permeability of no greater than 1 x 10~7 cm/s as determined bythe ASTM method for falling head permeability. It shall be placed in lifts no greater than 8 inches(before compaction).

Drainage Layer A minimum of 6 inches of an engineered aggregate will be placed on top of the claymineral resource. It will serve as the drainage layer and part of the frost protection layer. Appendix Gcontains a technical memorandum detailing the engineering justification for using a 6 inch thickdrainage layer in lieu of previously-proposed, thicker layers. The drainage layer material shall have apermeability of no less than 1 x 10"' cm/s as determined by ASTM Method D-2434 (constant headpermeability test).

Geotextile A non-woven geotextile will be placed between the drainage layer and the upperunclassified fill layer to prevent fines from migrating into the drainage layer and impeding lateralsubsurface drainage.

Upper Unclassified Fill (Frost Protection) Layer A minimum of 13 inches of unclassified mineral fillwill be placed on the geotextile. This layer, in combination with the drainage layer, geotextile, andtopsoil layer will provide a minimum of 25 inches of frost protection for the surface of the clay mineralresource barrier layer.

Topsoil Layer Six inches of resoiling medium will comprise the topsoil layer, which will be placedover the upper unclassified fill layer. The resoiling medium will be capable of sustaining a permanent,diversified mixture of grasses.Final Design Report gMotor Wheel Disposal SiteSharp and Associates. Inc95rpt.doc/rev. 4/30/97

Vegetation A permanent, diversified, self sustaining vegetative stand comprised of a mixture of grasseswill be established to maximize evapotranspiration, minimize erosion, and minimize desiccationcracking of the topsoil layer. The seeding, fertilizing, and mulching specification for the vegetativelayer is based on the United States Department of Agriculture Soil Conservation Service's Michiganoffice Technical Guide for Critical Area Planning, Publication 342-1. Two different seed mixtures willbe used. One will be for the milder slopes of the landfill area itself. The other mixture, featuring asignificant portion of crown vetch, will be applied to the north slope reconstruction area.

Storm Water Diversion The majority of storm water will be directed to the existing impoundment tothe north of the site, in the remnants of the former quarrying operation. Storm water conveyances havebeen designed to divert runoff generated by a 25-year storm event.

Soil Erosion Control Soil erosion control measures will be implemented in accordance with theMichigan Soil Erosion and Sedimentation Control Act, Public Act 347 of 1972. Permanent andtemporary soil erosion control will include seeding, mulching, silt fences, and straw bale filters, asshown the construction drawings and included in the Technical Specifications. A Soil Erosion AndSedimentation Pollution Control Application will be submitted to the Ingham County DrainCommissioner, in order to procure a permit.

Gas Venting The objective of passive gas venting is to prevent gas build-up beneath the cap materials,minimizing the potential for horizontal migration. Passive vertical gas vents will be installed at amaximum frequency of 1 vent per acre, or a maximum total of 13 vents. The vents will consist of 4-inch slotted PVC or high density polyethylene pipe, as shown the construction drawings. The ventswill placed in 12-inch-diameter borings augured to approximately 10 feet above the bottom of thewaste, maximizing the amount of waste exposed to the screened vent interval, while minimizing thepotential to penetrate through the bottom of the landfill. The annular space between the pipe andboring walls will be backfilled with pea gravel or equivalent granular material. The vents will becapable of being converted to active vents if future events warrant. A 4-foot long bentonite plug willbe placed between the borehole wall and vent pipe to hinder short circuiting of ambient air if a vacuumis applied to the vent. Solid-walled riser pipe will extended through the subgrade and cap to a height of6 feet above the final cover. The top of the riser pipe will be turned downward 180 degrees to preventrainwater from entering the vent. The gas vents will be constructed in such a way so that they could beconverted to soil vapor extraction points sometime in the future.

Frost-Protection The Predesign Report cites the Michigan Department of Labor, Bureau ofConstruction Codes report (1976) as stating that the average annual frost penetration in Ingham Countyis 25 inches beneath the surface. The drainage layer, geotextile, upper unclassified fill, and topsoillayer will amount to at least 25 inches of frost protection for the top of the 36-inch clay barrier layer.

Security Measures Fencing and warning signs will be installed to prevent vandalism and unauthorizedaccess to the site. A 6-foot-tall, chain link fence will be installed around the limits of waste. Threestrands of barbed wire will be placed on top of the fence, and a double, 12-foot-wide swing gate will beplaced at the entrance to the access road. Warning signs will be placed at 200-foot intervals along thefence and at the gate designating the site as a restricted area undergoing remedial action. A telephonenumber will be identified on the signs for additional information. Additionally, a reinforced pipe gatewill be provided between the fence and the main entrance from Lake Lansing Road.

Health and Safety The Health and Safety Plan covering construction activities is included as AppendixC.

2.1.2 North Slope Reconstruction Area

The north slope will be reconstructed to final grade of 3:1 (H:V), using only materials presently outsidethe limits of waste placement in the north slope area and imported fill! In essence the north slopereconstruction is a separate construction element. The existing materials of the north slope area havesufficient grain size and shear strength to achieve a minimum safety factor of 3 for a 3:1 slope, asdemonstrated by the calculations included in Appendix H. The minimum suggested safety factor forthis type of embankment is 1.5 to 2. Imported fill for the north slope will have to meet rigoroustextural and shear strength requirements, as detailed in the Technical Specifications, to maintain thestability of the slope. All embankment on the north slope will be compacted to 95% of the maximumStandard Proctor Density. To minimize potential erosion, two rows of post construction silt fence willbe installed and a seeding mixture specially recommended for critical planting on slopes will be used.

2.1.3 Health and Safety

A site Health and Safety Plan (HASP) has been created following the requirements and guidelines ofCFR 190.120. It prescribes procedures designed to minimize threats to human health and safety duringimplementation of the landfill remedy. The HASP is included as Appendix C.

2.1.4 Project Organization and Schedule

A remedial Action Work Plan, identifying key project personnel responsibilities, as well as a proposedproject schedule, is included as Appendix D.

2.1.5 Cost Estimate

The preliminary cost estimate for the construction of the landfill cap is $ 3,279,973. The estimatedannual operating costs are S 32,200. A breakdown of the construction and operating costs are providedbelow. All earthwork quantities are in-place. Estimated unit prices are based on prices from similarlyscoped projects as well as published construction cost estimating resources. It is assumed that allconstruction takes place in one season.

SECTION 3__________GROUNDWATER REMEDIATION SYSTEM

3.1 GLACIAL AQUIFER GROUNDWATER REMEDIATION SYSTEM DESCRIPTION

3.1.1 Groundwater Remediation Strategy

The groundwater plume in the Glacial Aquifer contains volatile organic compounds (VOCs), fluoride,and ammonia that require remediation. The extraction system will consist of a well in the perchedaquifer (landfill area), two wells along the southern boundary of the site (Zone 1), two wells locatedadjacent to MW-39 (Zone 2), and four or five wells located at the trailing edge of the ammonia plumenear MW-64 (Zone 3). The tentative locations for the extraction wells in Zones 1,2, and 3 are locatedon Figure 3-1 (page 14). The exact locations of these wells will be determined through a boringprogram. Several borings will be installed in the extraction areas in order to determine the optimumlocations for the wells. The detailed boring program was submitted under separate cover to MDEQ onNovember 6, 1996. A copy of the program is provided in Appendix J.

The extraction wells in the perched aquifer and in Zones 1 and 2 will remediate groundwater containingboth VOCs, fluoride, and ammonia. Groundwater containing VOCs, from Zones 1 and 2, will betreated using an air stripper prior to being discharged to the Grand River. The groundwater near Zone3 contains ammonia only. Groundwater from Zone 3 will be discharged directly to the Grand River(contingent upon an approved NPDES permit). A process flow diagram of the remediation system isprovided as Figure 3-2 (page 15) and as Groundwater Sheet FD-1 (in Appendix D). Air strippers havebeen proven as a reliable mechanism for the removal of VOCs from groundwater. An Operations andMaintenance Manual for the groundwater remediation system is provided in Appendix A and theHealth and Safety Plan for the system is provided in Appendix C. Construction of the system will beconsistent with the Construction QAPP, located in Appendix B, and the Remedial Action Plan, locatedin Appendix D.

The groundwater modeling performed for the Site indicates that in order to maintain hydraulic controlof the groundwater plume. Zone 1 and Zone 2 require pumping rates of 90 gallons per minute (gpm)each and Zone 3 requires a pumping rate of 80 gpm. The perched aquifer will be pumped at a rate ofapproximately 10 gpm. Zone 1 is near the site with the objective of capturing the higher contaminatedground water emanating from the site. Zone 2 is a cut off zone with the objective of capturing theplume before the aquitard separating the glacial and Saginaw aquifer thins out. Zone 3 is at the leadingedge of the plume to capture the balance of the glacial plume.

3.1.2 Basis of Design

Extraction Wells Based on the calculations and discussion provided in Appendix K, therecommendations for extraction well locations are provided below. The design of the extraction wellsis provided in the Extraction Well Boring Plan located in Appendix J.

Perched Well is located in the landfill. The Perched Aquifer Extraction Well has been located toaddress three objectives: to locate the well in the lower portion of the landfill to maximize the greatestavailable drawdown; to locate the well in an area where the highest observed concentrations ofcontaminants have historically been encountered; and to locate the well in an area of the landfill wheregreater wetted thicknesses were encountered during previous boring and testing programs.

elevation of the waste bottom has been identified in the central to northeastern portion of the landfillsite. The single deepest/lowest depth of waste was encountered at the FTC&H soil boring LC-7location. However, the boring logs for this borehole do not record the presence of water.

The area of highest contaminant concentrations were encountered in the Temporary Extraction Wells(TEW) #1 and #2, which were installed north and northeast of soil boring LC-7. Total recorded wettedsection thicknesses for TEW-1 and TEW-2 were approximately 12 feet and 21 feet respectively.

From a production perspective, LC-7 represents a less attractive location due to reported higher silt andclay content, while boreholes TEW-1 and TEW-2 were reportedly higher in coarser sediment fractionsand had greater observed fluid volumes present. South of TEW-1 and TEW-2, the perched aquifermonitoring well #61 also encountered coarser sediments. However, the reported gross wetted thicknessin MW-61 was limited and layered through the perched interval.

The selected Perched Aquifer Location is offset to well TEW-2. This site was selected because: it willencounter the lower/deeper section of the landfill; will be established in the area where the highestconcentrations of contaminants have been recorded; and is predicted to have greater accumulations ofpotentially productive materials.

Zone 1 is near the source. The modeling in the Predesign Report indicates that the plume can becaptured at the source by spacing two extraction wells along the proposed southern border of the Graceproperty. The wells on the sketch are approximately 250 feet apart centered east and west betweenMW12D and MW13D. The exact locations for these wells will be determined as outlined by the boringprogram in Appendix J. The wells are estimated to yield 45 gpm each.

Zone 2 is designed to cut off the plume before entry to the lower (Saginaw) aquifer. There are twowells in this zone to cut off the plume. The tentative well locations are between New York Avenue andMassachusetts Avenue along North Street. The exact locations for these wells will be determined asoutlined by the boring program in Appendix J. The wells are estimated to yield 45 gpm each.

Zone 3 is designed to extract the end of the plume and will be directly discharged to me river. The,aquifer in this area is thinner (~20 feet) requiring more wells. The exact locations for these wells willbe determined as outlined by the boring program in Appendix J. The wells are estimated to yield 20-25 ^gpm each. Based on initial production tests, there will be 4 or 5 wells that will be needed to providesufficient capture. For planning purposes, 5 wells are shown.

Air Stripper Flow from the perched aquifer, Zone 1, and Zone 2 will be routed to an air stripper forVOC removal. Based upon review of the discharge standards, no treatment will be required forammonia. Since no treatment is required for ammonia and VOCs are not present (or are belowconcentrations requiring treatment), water from Zone 3 will be discharged directly into the GrandRiver.

A low profile Shallow Tray Aeration System, manufactured by North East Environmental Products,Inc., was chosen for VOC removal at this site primarily because of it's high removal efficiency andresistance to fouling. The low profile air stripper consists of several sequential trays in which air isbubbled through the VOC-containing groundwater causing the VOCs to be stripped. A low profile airstripper is being used at this site because it can meet the anticipated discharge limitations and will beless susceptible to fouling by calcium and iron precipitation. The anticipated discharge limits for VOCsare their respective MCLs. Sampling of the effluent will be conducted as required by the NPDESFinal Design Report i f.Motor Wheel Disposal SiteSharp and Associates, Inc95rpt.doc/rev. 4/30/97

permit to ensure compliance. An air emissions study for the site has been reviewed and approved byMDEQ.

The design flow rate for .the groundwater remediation system is approximately 190 gpm. The airstripper was sized for'550 gpm in the event that the flow rate is increased by incorporation of theSaginaw aquifer extracltoti wells. Oversizing the air stripper will also decrease the requiredmaintenance. In addition, a 3-way valve was added to the effluent line of the air stripper to recycle aportion of the effluent. Recycling of the effluent will increase the overall removal efficiency of the airstripper. The concentrations used for sizing the air stripper are provided in Table 3-1. Theseconcentrations were obtained by calculating a "worst case" flow-weighted average concentration fromselected well data. The remediation system incorporates optional acid injection equipment in the eventthat precipitation causes significant operating problems. If required, the acid can be introducedupstream of the air stripper to reduce the pH of the water stream thereby reducing precipitation. Thisequipment was included in order to design the remediation building and piping; it will not be installedunless it is needed. The testing process to determine whether acid feed is necessary is described inSection 3.5 of the Operations and Maintenance Manual (Appendix A).

Remediation System Building The air stripper, controls systems, and optional acid feed system will behoused in a 62' by 28' building located on the southwest side of the property (Groundwater Sheet 3KP-1 in Appendix L). The building will be constructed of concrete block and be surrounded by a fence forsecurity. Details of the building are located on Groundwater Sheets A-l, A-2, A-3, S-l, PH-PP1, PH-PP2, E-l, and E-2 (Appendix L).

System Piping The routing of the system pipelines is provided in Groundwater Sheet KP-1 (AppendixL). Easements have been obtained from the railroads to install the piping along this route. The systempiping was designed as a forcemain system. The calculations for each section of pipe are provided inAppendix M.

System Controls The operation of the groundwater remediation system will be controlled byprogrammable logic controllers (PLCs). Since several of the extraction wells are located a significantdistance from the remediation system building, several PLCs are required. Control over the entiresystem will be accomplished using one PLC located in the remediation system building. It will controlthe treatment system equipment, the perched aquifer well, and the Zone 1 wells. Extraction wells inFinal Design ReportMotor Wheel Disposal SiteSharp and Associates.

zones 2 and Zone 3 will each contain PLCs that report directly to the PLC in the treatment systembuilding via variable frequency radios. The control logic for the system is provided in Appendix N.

3.1.3 Applicable or Relevant and Appropriate Requirements

Water discharges to the Grand River will be regulated by Michigan Act 245 of the Public Acts of 1929,as amended, Part 4, Rule 57 Water Quality Standards (Rule 57). Rule 57 establishes surface waterdischarge criteria for the target VOCs among other parameters using Water Quality Based EffluentLimitations (WQBELs), Treatment Technology Based Effluent Limitations (TTBELs), andantidegradation criteria. At the present time, it is anticipated that the discharge standards for each ofthe VOCs will be no more stringent than the drinking water maximum contaminant levels (MCLs).Modeling of the ammonia discharge was performed (FTC&H, Final Additional Studies/PredesignReport, 1996) using the Streeter-Phelps Dissolved Oxygen Model to predict water quality effects. Thismodeling indicates that the anticipated discharge of ammonia to the Grand River would not cause adegradation of water quality and subsequently no treatment will be required.

The emissions limitations of VOCs from the air stripper will be based on the air toxic regulationsdeveloped by the MDEQ Air Pollution Control Commission, as defined under Administrative Rule No.R336.1230. This ruling states that the VOC concentration in the air discharge must not exceed the"maximum allowable emission rate based on the application of best available control technology fortoxics (T-BACT)" and the "initial threshold screening level" (ITSL) or the initial risk screening level(IRSL) or both." The IRSL takes precedence when the compounds are suspected carcinogens.

3.5 SAGINAW GROUNDWATER REMEDIATION SYSTEM

The impact of the MWDS on the Saginaw Aquifer has been investigated by multiple consultants sincethe site was listed on the National Priorities List (NPL) on October 4, 1986. Sharp and Associates,Inc. (SHARP) has continued the investigation of the Saginaw Aquifer since January 1995. The InterimReport of the Investigation of the Saginaw Aquifer (Saginaw Report) was provided to the U.S. EPAand the MDEQ on November 18, 1996.

The conclusions published in the Saginaw Report state that the Saginaw Aquifer in the region south ofMWDS has been affected by the MWDS. The constituents of concern identified within the Saginawinclude ammonia, fluoride and vinyl chloride. These compounds are included in the suite of MWDSrelated contaminants that have been identified within the overlying Glacial Aquifer. The potentiometricdata collected determined that the dominant, natural Saginaw groundwater flow gradient is to thenorthwest. However, the City of Lansing's North Well Field and its seasonal municipal water demandshave been shown to cause localized variations to the Saginaw groundwater flowpaths.

Field investigations and laboratory analyses have shown that MWDS - related ammonia, and vinylchloride contaminant plumes are present in the Saginaw Aquifer. The ammonia plume occupies anarea of approximately 200 acres and the vinyl chloride plume an area of nearly 85 acres. The vinylchloride contaminant plume mass is wholly contained within the area of the ammonia plume. Bothgroundwater plumes lie to the east and southeast of the City's North Well Field.

SHARP considered in the design of the pipelines and treatment system the potential impact for theSaginaw active remediation. The actual extraction well location(s) are unknown at this time as theplumes are not completely delineated. However, based on the current interpretation of the Saginawaquifer ammonia and vinyl chloride plumes, an approximation of the extraction rates for the Saginawaquifer can be made. For a potential active pumping alternative in the Saginaw aquifer, two extractionwells are envisioned. Each well would be designed to produce at a rate of 100 gallons per minute, andwill have a calculated 1,200-1,500 foot radius of capture after the first 6 months of operation, therebycapturing the plume mass and preventing the North Well Field's area of pumpage influence fromdrawing the contaminants into this part of the municipal water supply. The glacial aquifer pumpingsystem will cut off further leakage into the Saginaw and reduce the remediation time.

For design purposes, the pipelines designed to convey water to and from the ground water treatmentplant located on the MWDS property have been oversized to accommodate increased flow from theSaginaw aquifer (an allocation of 200 gpm). Additionally, the treatment equipment (i.e., Shallow TrayAeration System) has been oversized to accommodate treating of up to 300 gpm above the requiredneeds of the glacial system (i.e., STAS design at 500 gpm less 200 gpm for glacial = 300 gpmadditional for Saginaw, if needed).

There are currently a number of activities that need to be conducted prior to finalizing any activepumping centers in the Saginaw aquifer including: well profiling of select BW&L wells for furtherdelineation; installation of additional monitoring wells in the Saginaw in the spring of 1997; andresolution of the ammonia cleanup standards with USEPA and MDEQ.

1.1 BACKGROUND

The MWDS is a 24-acre property located at 1401 Lake Lansing Road on the northeast edge of the Cityof Lansing, Michigan. The site lies in the NE 1/4 of the SW 1/4 of Section 3 in Lansing Township(T4N, R2W), Ingham County, Michigan (refer to Figure 1 in Attachment A). The property was usedby Motor Wheel Corporation as a disposal site for industrial wastes from 1938 until about 1978 (USEPA, 1991). The types of disposed wastes included solid and liquid industrial wastes, such as paints,solvents, liquid acids, caustics, and sludges. Wastes were disposed of on the property in tanks, barrels,seepage ponds, and open fill operations (US EPA, 1991).

Between 1970 and 1982, at least three cleanup actions were initiated, which resulted in the excavationand offsite disposal of waste materials (Hunter/Keck Environmental Services [Hunter/Keck], 1990). In

O&M Manual f^_ JMotor Wheel Disposal SiteSharp and Associates, Inc.OM. doc/5104-16/5/2/97

1970, the MDNR requested that the Motor Wheel Corporation remove solid wastes, paint sludges, andoils from seepage pond areas for disposal offsite. Some of the excavated materials were disposedoffsite and the former pond areas were backfilled (US EPA, 1991). Three 10,000-gallon tanks, theircontents and contaminated soil, and fill surrounding the tanks were removed and disposed offsite inDecember 1982. An unknown number of drums were also disposed of offsite at this time (US EPA,1991).

In 1978, MSV Associates acquired the property and began open-pit sand and gravel mining. Themining operations exposed some of the buried industrial wastes. The exposed materials weresubsequently excavated, stockpiled on the western part of the site, and covered with clay (US EPA,1991).

The site was placed on the National Priorities List on October 4, 1986 (50 FR 41015). On June 26,1987, Motor Wheel Corporation, W.R. Grace & Co. (Grace), and The Goodyear Tire & RubberCompany signed an AOC agreeing to conduct a Remedial Investigation (RI) and Feasibility Study (FS)at the MWDS (US EPA, 1991). The ROD for the Site was signed in September 1991. Goodyear,Grace, Textron, and the Lansing Board of Water and Light entered into a consent agreement to conductthe Remedial Design for the Site in 1992.

Site gravel/sand mining operations were discontinued in 1987. MSV Associates is the current owner ofthe property. The site is presently inactive (US EPA, 1991).

1.2 SOURCE OF CONTAMINATION

Previous studies by others have determined the character and extent of contaminants associated with theMWDS and their distribution in the shallow unconsolidated sand and gravel groundwater aquifers(Glacial Aquifer). The Glacial Remedial Investigation determined that the source of the glacial plumeis the landfill and the plume extends approximately 2 miles South of the site.

The impact of the MWDS on the Saginaw Aquifer has been investigated by multiple consultants sincethe site was listed on the National Priorities List (NPL) on October 4, 1986. Sharp and Associates,Inc. (SHARP) has continued the investigation of the Saginaw Aquifer since January, 1995. TheInterim Report of the Investigation (RI) of the Saginaw Aquifer was provided to the U.S. EPA and theMDEQ on November 18, 1996.

The conclusion published in the RI states that the Saginaw Aquifer has been impacted by the MWDS.The constituents of concern identified within the Saginaw include ammonia, and vinyl chloride. Thesecompounds are included in the suite of MWDS related contaminants that have been identified within theoverlying Glacial Aquifer. The RI has determined that the dominant, natural Saginaw groundwaterflow gradient is to the northwest. However, the City of Lansing's North Well Field and its seasonalmunicipal water demands have been shown to cause localized variations to the Saginaw groundwaterflowpaths.

Field investigations and laboratory analyses have shown that MWDS-related ammonia and vinylchloride contaminant plumes are present in the Saginaw Aquifer. The ammonia plume occupies anarea of approximately 200 acres and the vinyl chloride plume an area of nearly 85 acres. The vinylchloride contaminant plume mass is wholly contained within the area of the ammonia plume. Bothgroundwater plumes lie to the east and southeast of the City's North Well Field.O&M Manual ^_2Motor Wheel Disposal SiltSharp and Associates, Inc.OM. doc/5104-16/5/2/97

Most of the waste material present at the Motor Wheel Disposal Site lies directly on top of a clay-richlayer. The clay-rich layer contains an upper perched zone and a lower perched zone. The lowerperched zone appears to be hydraulically connected to the upper perched zone. The Glacial Aquiferlies approximately 25 feet below the base of the waste mass. There are windows, or natural holes, inthe perching clay layers that allows vertical migration of leachate or contaminants into the lower glacialaquifer. Most of the perched aquifer water is derived from infiltration of precipitation in the immediatearea of the waste mass.

1.3 PERFORMANCE OBJECTIVES

The groundwater remediation system has been designed in order to comply with the Record of Decision(ROD) signed on September 30, 1991. The contaminants of concern at the site are chlorinated volatileorganic compounds (VOCs), fluoride, and ammonia. These contaminants shall be removed to complywith the ROD cleanup criteria. In June, 1995, Michigan amended the Michigan EnvironmentalResponse Act, Act No. 307 of 1982 and incorporated the amended act into the National Resources andEnvironmental Protection Act, Act No. 451 of 1994. This new legislation included changes in thecleanup standards that were previously cited as Applicable or Relevant and Appropriate Requirements(ARARs) in the ROD. The PRP group prepared an evaluation of the cleanup standards to USEPA andMDEQ. The final cleanup standards for ammonia is currently under review. A copy of theremediation system's draft National Pollution Discharge Elimination System (NPDES) permit isprovided in Appendix P of the Final Design Report.

The groundwater extraction and treatment system shall operate for a minimum of 10 years as stated inthe Administrative Order of Consent. After 10 years of operation, the clean-up standards and riskassessment will be re-evaluated to determine the need for continuing operation of the groundwatersystem.

SECTION 2.0 SYSTEM OVERVIEW/PROCESS DESCRIPTION———————————————————————————————————————————The groundwater plume in the Glacial Aquifer contains VOCs and ammonia that require remediation.The extraction system consists of one well in the perched aquifer (landfill area), two wells along thesouthern boundary of the site (Zone 1), two wells located in the vicinity of MW-39 (Zone 2), and fivewells located at the trailing edge of the ammonia plume near MW-64 (Zone 3). Zones 1 ,2 , and 3 arelocated on a map on Figure 2 in Attachment A.

The extraction wells in the perched aquifer and in Zones 1 and 2 remediate groundwater containingboth VOCs and ammonia. Groundwater containing VOCs, from Zones 1 and 2, is treated using an airstripper prior to being discharged to the Grand River. A process schematic of the treatment system islocated in Figure 3. The groundwater near Zone 3 contains ammonia only. Since ammoniaconcentrations in the groundwater are below applicable Michigan discharge limits, the groundwaterfrom Zone 3 is discharged directly to the Grand River. The system has not been installed yet, so welllocations may be modified based on field results. However, the operation of the system is the same.For the purpose of this O&M manual, it is assumed that the number and location of the extraction wellsremains unchanged. A schematic of the system is located in Attachment A.

The contaminants requiring attention in the groundwater plume in the Saginaw Aquifer includeammonia and vinyl chloride. Sharp has presented a design that has the contingency for two Saginawgroundwater extraction wells be installed downgradient to the contaminant plume areas. Thegroundwater will be treated using an air stripper prior to being discharged to the Grand River.Although the Saginaw delineation is not fully completed, SHARP feels that the existing system andpipelines can accommodate the additional flow. See Section 3.5 of the Design Report for a furtherdiscussion of the Saginaw strategy.

A list of the major system components is provided in Table 2-1. Refer to the drawing in Appendix L ofthe Final Design Report for location and specification of each piece of equipment. The vendorspecification sheets and instruction manuals for each piece of equipment are provided in Attachment B.

2.1 EXTRACTION WELLS AND PUMPS

2.1.1 Extraction Well Overview

The purpose of the extraction wells is to control and intercept the groundwater contaminant plume,down-gradient of the MWDS. In addition to the extraction wells, monitoring wells are utilized forperformance monitoring, water level measurements, and for analytical sample collection points.

The number and spacing of the extraction wells was designed to maintain hydraulic capture of thegroundwater plume. The perched aquifer well will pump at a rate of 10 gpm. Zone 1 is located nearthe site with the objective of capturing the higher contaminated groundwater. Two extraction wells willbe placed along the southern boundary of the Grace property. These wells will be placedapproximately 250 feet apart centered east and west between MW12D and MW13D (refer to drawingsin Appendix L of the Final Design Report). These wells will pump at a rate of 45 gpm each.

Zone 2 is the cut off zone designed to cut off the plume before entry to the lower Saginaw aquifer.Two wells will be placed in this zone between New York Avenue and Massachusetts Avenue along

O&M Manual A-4Motor Wteel Disposal SileSharp and Associates, Inc.OM.doc/5104-16/5/2/97

North Street (refer to drawings in Appendix L of the Final Design Report). These wells will pump at arate of 45 gpm each.

Zone 3 is designed to extract the end of the plume and is directly discharged to the river. More wellswere required in this zone since the aquifer in this area is thinner and therefore each well is not capableof yielding as much water as Zones 1 and 2. Five wells will be installed pumping at 16 gpm each.

The actual well locations for the Saginaw groundwater extraction wells are unknown at this time as theplumes are not completely delineated. However, based on the current interpretation of the Saginawaquifer ammonia and vinyl chloride plumes, an approximation of the extraction rates for the Saginawaquifer can be made. For a potential active pumping alternative in the Saginaw aquifer, two extractionwells at 100 gpm each are envisioned thereby capturing the plume mass and preventing the North WellField's area of pumpage influence from drawing the contaminants into this part of the municipal watersupply. The glacial aquifer pumping system will cutoff further leakage into the Saginaw and reduce theremediation time.

The Glacial and Saginaw Aquifer extraction system represents a dynamic system and was developed tocontrol and treat the off-site migration of chemicals by creating a hydraulic barrier.

2.1.2 Extraction Well Pumps

All extraction well pumps chosen were Grundfos 4-inch stainless steel submersible pumps (orequivalents). These pumps have built-in jam-free check valves designed for fail-safe operation.OIM ManualMotor Wheel Disposal SiteSharp and Associates. Inc.OM.doc/5104-16/5/2/97

A-5

Precision Form impellers are fabricated from stainless steel to provide for long pump life, maximumhydraulic efficiency, and top performance. An exclusive Prime Inducer provides maximum pumpprotection from dry-run damage during low water situations. The pump inlet is totally screened toprevent damage from debris. These pumps (equivalents) will be installed during the construction phaseof the project.

2.2 AIR STRIPPER

A three tray 304L stainless steel Shallow Tray low profile air stripper, manufactured by North EastEnvironmental Products, Inc., will be installed to remove VOCs at this site primarily because of itshigh removal efficiency and resistance to fouling. The low profile air stripper consists of severalsequential trays in which air is bubbled through the VOC-containing groundwater. The bubbled airstrips the VOCs from the groundwater.

The design flow rate for the groundwater remediation system is approximately 190 gpm. The airstripper was sized for 550 gpm in the event that the flow rate is increased and to accommodate flowfrom the Saginaw aquifer. Oversizing the air stripper will also decrease the required maintenance.

2.3 ACID INJECTION EQUIPMENT

The remediation system was engineered to provide for the installation of acid injection equipment in theevent that precipitation causes significant operating problems. If required, the acid can be introducedupstream of the air stripper to reduce the pH of the water stream thereby reducing precipitation. Theacid injection equipment has not been installed at this time. If an acid injection system is needed, theacid feed rate will be controlled with a PID feedback loop using the downstream pH at the shallow traysump.

2.4 FLOW METERS AND FLOW TOTALIZER

Steel flow meters will be installed to measure groundwater flow from the extraction wells and throughthe remediation system. The flow meters to be installed will be similar to Sensus Magnetic DriveTurbo Meters. The Turbo Meter registers flow by combining the magnetic actions of a driver magnetembedded in the rear face of the rotor, a three-legged flux carrier and a cylindrical follower magnetattached to the gear train shaft inside the registers magnet well. Water flows through the meter causingthe meter's rotor, with magnet, to turn. As one of the magnet poles passes one of the flux carrier legs,the magnetic force is transmitted through the flux carrier leg to the follower magnet, causing theregister shaft to rotate. The rotor assembly is the only moving part in the water.

The flow meters will be installed with a flow totalizer similar to the Sensus Act-Pak (Automatic ControlTranslator Package) electronic instrumentation package. The Act-Pak instrument accepts pulses forcontact closures from the flow meters to provide flow rate data.

2.5 DISCHARGE PUMPS

The air stripper will utilize two discharge pumps for transferring treated water to the outfall. Thesepumps will be Gorman-Rupp Model 83A3-B self priming pumps (or equivalent).

2.6 PROGRAM LOGIC CONTROLS

The MWDS remediation system consists of extraction wells and an air stripper treatment facility. Theextraction wells are broken down by zones with each zone being controlled by an Alien-BradleyProgram Logic Controller (PLC). The PLC located in the treatment system building is designated asthe system master, and the PLC's located at the "remote" sites are designated as slaves to the mastersite. "Linking" of the remote and master sites is accomplished through use of the communicationschannel 0 on the PLC's and spread spectrum radio modems. Use of the radio modems prevents theneed for "hard-wiring" between sites, or the use of designated leased telephone lines. To allow fortotal system overview and control, supervisory software shall communicate via communication channel1 on the master PLC. This supervisory software provides a graphical interface between operators andthe PLC's. Plant control, system alarms, and historical data trending are all accomplished through theuse of supervisory software. Detailed information of the supervisory software can be found in Section3. Oof Attachment E.

2.7 3-WAY VALVE

A 3-inch 3-way pneumatic actuated valve will be installed to recycle effluent to the Shallow Tray AirStripper (STAS) System by means of directing the discharge back to the STAS or to the main output.This recycle will improve the efficiency of the STAS. This 3-way valve will maintain the water levelbetween the high and low level switches (refer to Attachment E) for cycling the STAS discharge pump.This should allow the pump to remain on and prevent excessive cycling. The valve comes equippedwith positive shutoff in each direction and will be controlled by the treatment systems PLC.

2.8 AIR COMPRESSOR

A 5-HP Quincy Model QRDS-5 air compressor will be used to operate the 3-way valve. The aircompressor features permanently lubricated/oil-less, direct drive design which eliminates belts andpulleys as well as oil changes. The compressor features a high torque motor with built-in thermalprotection and a durable, metal housed 4-part regulator and gauge with auto pressure setting. Thepressure range is set at 95 psi on/125 psi off with a 50/50 duty cycle. The air compressor requires 230volt, 60 Hz, 10 amp service.

2.9 SYSTEM PIPING

Diagrams, showing piping size and locations, have been provided in Appendix L of the Final DesignReport. Attachment G of the Operations and Maintenance Manual will contain the as-built drawingsfor the system.

2.10 REMEDIATION SYSTEM BUILDING

The air stripper and controls systems are housed in a 62' by 28' building located on the southwest sideof the property. The building was constructed of concrete block and surrounded by a fence forsecurity. Details of the building are located in Appendix L of the Final Design Report.

2.11 PURGE WATER TANK

The purge water tank will be used to introduce well purge water, developed during the purging andsampling of the various wells on-site, and air stripper cleaning water into the air stripper for treatment.The tank will have a capacity of 300 gallons. Water will be transferred from the tank to the air stripperby a Little Giant 14EH-CIM or equivalent pump.

SECTION 3.0_______________________SYSTEM START UP

This section details the start up procedures for the major pieces of equipment to be used for thegroundwater remediation system.

3.1 EXTRACTION WELL PUMPS START UP

The Grundfos extraction well pumps (or equivalent) will be started by utilizing the Program LogicController (PLC). The pumps will be turned on and each pump's flow meter monitored to verifygroundwater flow. Additionally, the control system is equipped with a safety check of the extractionsystem (refer to Attachment E). The PLC will send an alarm if the pump produces no flow.

3.2 AIR STRIPPER START UP

The air stripper must be started according to the manufacturer's specifications in Attachment B.

1. Turn off all electrical components associated with the unit and close drain and sample valves (besure the sight tube valve is open).

2. Fill the sump tank with one foot of clean water. The sump tank can be filled via the clean-outports, on the left side of the unit, or through the inlet piping.

3. Turn on the master power disconnect switch on the power disconnect panel.4. Check the blower rotation by momentarily switching on the blower switch and observing whether

the blades turn in the direction of the arrow on the blower casing. If blower rotation is correct,open the air inlet damper to 14 open and turn the blower switch to "ON".

5. Start the clean water flow to the unit.

Let the feed water and blower run for about two minutes then shut them off. When the wheel to theblower stops spinning, restart both the blower, and the water flow. This procedure should fill the inletchambers. If the seal pots will not fill by this method, the operator can fill them manually. First tryspraying a stream of water through the clean-out ports, on the left side of the unit. The stream of watermust be sprayed straight across the system and hit the opposite side. The splashing action should fillthe pots. If the preceding methods do not work, remove the trays, fill the seal pots, re-assemble, andre-start.

After the unit has been operating for about 5-10 minutes, check the air pressure readings permanufacturers' recommendations (refer to manufacturers' specifications in Attachment B). Adjust thedamper to obtain the proper readings. Connect the contaminant feed water line. The system is readyfor operation. It is not necessary to perform initial start up procedures each time the system is shutdown, the system will already be primed from the last run.

3.3 DISCHARGE PUMP START UP

The discharge pumps will be started according to the manufacturer's specifications. Prior to startup,the pump will be primed and its rotation checked to ensure proper operation.

O&M Manual ^_gMotor Wheel Disposal SiteSharp and Associates. Inc.OM.doc/5104-16/5/2/97

3.4 CALIBRATION OF ELECTRONICS

Confirming that the electronic sensors are correctly calibrated is to be done every month for the firstthree months of operation. This frequency is necessary to establish baseline readings for the electronicdrift of each sensor. At the end of the first three month period, the calibration procedure shall be doneperiodically if no drift is encountered. While the sensors are expected to remain stable over longperiods, the maximum calibration interval must be no longer than twelve months. If at any timereadings from sensor becomes erroneous, that sensor must be examined for calibration and confirm thatit is still functioning properly. Calibration of each sensor is done using a two point, linear method byfinding the offset and then the slope of the line created by the two data points.

3.4.1 Water Level Transducers

The pressure transducers, located in each extraction well, are calibrated by obtaining the PLC readingwhen the transducer is out of the water. This reading is the offset. The second reading is obtained bylowering the transducer to a known depth and then reading the output on the PLC. Preferably thereading at depth is taken when the depth is near the maximum normally encountered to minimize sensorerror.

3.4.2 Flow Meters

Refer to manufacturers specification sheets located in Attachment B.

3.5 EVALUATION OF ACID FEED SYSTEM

Minerals (including iron and calcium) tend to precipitate out of groundwater during the aerationprocess. This is commonly referred to as fouling. The shallow tray air stripper is designed to be foul-resistant, however, proper steps must be taken when dealing with high mineral concentrations. The airstripper shall be inspected periodically during the first three months of operation to determine ifprecipitation will be a problem. The maximum inspection interval must be no longer than two weeksduring the 3 month start up period. The inspection shall consist of visually inspecting the trays on theair stripper to ensure fouling is not occurring. The trays can be inspected by removing the clean outport covers and shining a light on the trays to ensure no deposits have developed around the aerationholes. Abnormally high pressure readings on the air stripper is a signal the air stripper is fouled.

The remediation system was engineered to provide for the installation of sulfuric acid injectionequipment in the event that precipitation causes significant operating problems. If precipitation isdeemed a problem, the acid feed system will be installed upon approval from all applicable agencies.Sulfuric acid can be introduced upstream of the air stripper to reduce the pH of the water streamthereby reducing precipitation.

SECTION 4.0 SYSTEM OPERATIONS AND MAINTENANCE'

This section details the system operation procedures along with the system components maintenancerequirements and frequency. A trouble shooting guide has been included in Attachment C in order toassist maintenance personnel in the event of system failure. The trouble shooting section will beprovided after system startup and shakedown.

4.1 MONITORING FREQUENCY

Operational parameters (including flow rates, run times, and water levels) of the system shall bemonitored monthly so that system performance can be evaluated and maintenance and repair activitiescan be scheduled, which will minimize cost and system downtime. During initial operation of thesystem, data collection shall be weekly, to account for the greater likelihood of operationalirregularities associated with start up. The program logic controls shall be used to verify properoperation of the remediation system. This shall involve periodically calling the system remotely to besure all components of the groundwater remediation system are operating normally. The groundwatermonitoring and sampling plan is located in Attachment F of this document.

4.1.1 Flow Meters

The treatment system consists of ten extraction wells, each well equipped with a flow meter. Inaddition, the discharge line and recycle line also contain flow meters. All flow meters will bemonitored remotely. The flow meters shall be periodically read and the readings recorded to ensureproper operation of the extraction wells and groundwater remediation system. The completegroundwater monitoring and sampling plan is located in Attachment F.

An air flow meter is located on the air stripper. The air flow meter shall be read and recorded duringsampling events to ensure proper operation of the air stripper.

The remediation system is equipped with an Alien-Bradley PLC control system. The control system isequipped with a safety check of the extraction pumps. The PLC sends a run signal to the pump whichactivates a timer. If the pump turns on the timer is deactivated. However, if the timer times out at oneminute, this indicates the pump has the signal to run, but is not producing flow. This will then signalan alarm system in the supervisory control system. The air stripper is equipped with a high-high levelswitch. If the high-high level switch is activated the system will shut down and an alarm signal will besent to the supervisory control system (for a complete explanation of the PLC refer to Attachment E).In the event an extraction pump or the air stripper shuts down, maintenance personnel shall be notifiedusing the system's PLC and autodialer and shall respond to evaluate the system.

4.1.2 Air Pressure Gauges

The shallow tray air stripper comes equipped with an air pressure gauge that shall be read and recordedduring sampling events.

The remediation system is equipped with an Alien-Bradley control system. The control system isequipped with a high-high level switch on the air stripper. If the high-high level switch is activated thesystem will shut down and an alarm signal will be sent to the supervisory control system (for a

O&M Manual A J 1Motor Wheel Disposal SiteSharp -nd Associates, Inc.OM.doc/5104-16/5/2/97

complete explanation of the PLC refer to Attachment E). In the event the air stripper shuts down,maintenance personnel shall be notified and shall respond to evaluate the system.

4.1.3 Water Level Transducers

The extraction wells contain water level transducers so that the effectiveness of each extraction well canbe determined remotely using the systems PLC. During the first quarter of operation, the water levelsin the extraction wells shall be recorded weekly to ensure proper capture of contaminant plumes. Afterthe first quarter of operation and after all the adjustments to the system have been made, the waterlevels shall be recorded monthly.

4.2 SAMPLING PROCEDURES

Samples shall be immediately placed in a sample cooler so that a temperature of approximately 4°C canbe maintained until they are delivered to the analytical laboratory. Standard chain-of-custodyprocedures and other shipping protocols shall be used for all samples.

All samples collected at the site and sent off for laboratory analysis will be analyzed in accordance withthe Quality Assurance Project Plan (Hunter/Keck, 1988) approved for the site.

The complete groundwater monitoring and sampling plan is located in Attachment F. The monitoringwells shall be sampled for at least 10 years. At the end of 10 years U.S. EPA, after a reasonableopportunity for review and comment by the State, shall determine the need for additional monitoring.If contaminants fall below and remain below cleanup standards, the PRP Group may petition to adjustthe number of monitoring wells and parameters.

4.3 SYSTEM MAINTENANCE

System maintenance shall be performed according to manufacturers' specifications. Themanufacturers' specification sheets are located in Attachment B. Table 4-1 lists a summary of themaintenance to be performed on the system.

4.3.1 Extraction Well Pumps Maintenance

The extraction well pumps will be serviced according to the manufacturer's specifications.

4.3.2 Well Maintenance

Each extraction and monitoring well shall be inspected for corrosion, damage to the lock, positivedrainage (damage to the concrete apron if applicable) and general integrity each time water qualitysamples or water level data are collected. Well numbers shall be checked for legibility and relabeled asnecessary. The total depths of all monitoring wells are measured to the nearest 0.1 foot periodically.These measurements are compared to installed depths to evaluate changes in the depth of the well (i.e.silt build up, obstruction) with respect to the screened Glacial Aquifer interval. The results of the welldepth measurements are compared to the original completion depths of the wells. Wells which aredamaged beyond repair or which become unusable for some other reason will either be replaced or analternate well designated.0AM Manual A-12Motor Wheel Disposal SiteSharp and Associates, Inc.

4.3.3 Air Stripper Maintenance

The shallow tray air stripper shall be visually inspected during sampling events to ensure normaloperation. The air stripper shall be inspected for leaks and/or abnormal operation with all observationsrecorded in the field book.

Minerals (including iron and calcium) tend to precipitate out of groundwater during the aerationprocess. This is commonly referred to as fouling. The shallow tray air stripper is designed to be foul-resistant, however, proper steps must be taken when dealing with high mineral concentrations. The airstripper shall be inspected periodically during the first three months of operation to determine ifprecipitation will be a problem. The maximum inspection interval must be no longer than two weeks.The inspection shall consist of visually inspecting the trays on the air stripper to ensure fouling is notoccurring. The trays can be inspected by removing the clean out port covers and shining a light on thetrays to ensure no deposits have developed around the aeration holes. Abnormally high pressurereadings on the air stripper is a signal the air stripper is fouled. Refer to the manufacturer's spec sheetslocated in Attachment B for suggestions on how to reduce high mineral concentrations in the influentflow and for the recommended cleaning procedure for a fouled air stripper. The use of any chemicalsfor cleaning the air stripper must be approved in the NPDES permit if the compound is to bedischarged to the Grand River.

4.3.4 Discharge Pump Maintenance

The discharge pumps will be serviced according to the manufacturer's specifications.

4.3.5 Air Compressor Maintenance

Quarterly inspect the air compressor for leaks and abnormal noises. Also, drain the water from the aircompressors tank. The air compressor will be serviced according to the manufacturer's specifications.

4.4 LANDFILL COVER MAINTENANCE

An engineered cap and landfill cover system will be installed at the Motor Wheel Disposal Site toprovide a low-permeability, high evapotranspiration, barrier to the subsurface materials. This cap shallbe inspected quarterly with the following observations recorded in the field book. Those observationsshall include:

• Location and description of any seeps• Loss of vegetation• Erosion• Verify drainage outlets are free of foreign matter

Any problems discovered with the cap shall be handled with consent of the supervising engineer. Theproblem shall be evaluated, optimal solution determined, PRPs notified if deemed a major problem andgiven chance for comment. Once a solution has been agreed upon, the plan of action shall immediatelybe put forth.

SECTION 5.0 SYSTEM PERFORMANCE EVALUATION———————————————————^————^———-——————Once the system is on-line, the performance of the system will be verified. There are two categories ofperformance: treatment of contaminated water by the Shallow Tray Air Stripper and hydraulic capture.The former shall be evaluated by comparing the influent concentrations of groundwater contaminants tothe effluent concentrations of groundwater contaminants of the air stripper to ensure appropriatetreatment of the groundwater. The later will be evaluated by determining the cone of capture and theconcentration trends of the monitoring wells. The evaluation criteria are discussed below.

5.1 VERIFICATION OF HYDRAULIC CAPTURE

Hydraulic capture shall be evaluated on a quarterly basis. Baseline data shall be gathered monthly from thebackground transducer and the system's transducers along with pumping rates from the extraction wells.The Troll data loggers will be programmed to gather data on at least a daily basis. During the initial threemonths of operation, electronic monitoring of the water levels will be done on a weekly basis to evaluatesystem performance, verify capture, and adjust pumping rates. The capture zones will be calculated usingstandard industry methods and graphically displayed on the groundwater table maps for the period. Duringthe initial shakedown period, capture zone equations based upon the Dupuit assumptions will be used.After the extraction well system approaches equilibrium with the aquifer, USEPA approved computer codesmay be used on a continuing basis for this task.

The data which are reduced to evaluate hydraulic capture include manual water level measurements frommonitoring wells (see Attachment F, comprehensive Groundwater Monitoring and Sampling Plan),electronic water level recordings from a transducer in a background monitoring well, from transducers inthe extraction wells, and electronic water level measurements from the compliance monitoring wells locatedlaterally from the extraction wells. The electronic data will be retrieved from the extraction wells viatelemetry and from the compliance wells manually by downloading these data monthly or quarterly inpreparation of the quarterly evaluation of groundwater hydraulic capture. The hydrographs from the dataloggers in the compliance well network and the background well will be evaluated to distinguish naturalfluctuations in the groundwater table from pumping the extraction wells.

Evaluation of extraction well maintenance records will be performed to evaluate system performance and topredict potential problem areas. This routine evaluation will be completed on a quarterly basis initially thenon a less frequent basis as baseline data is gathered with findings and corrective actions taken (as necessary)presented in the monthly reports. Data evaluation will include:

• Compilation of a listing that summarizes maintenance activities for the period.• Construction of graphical plots comparing well characteristics over time.• Analysis of capture zones. The capture zones will be displayed on the water level maps.• A review of equipment performance, primarily of the system's pumps and flow meters.

Graphical plots of specific capacity, observation well differential, and recovery data will be constructed asappropriate in order to track system efficiencies over time. In order to account for interference frompumping, observation well differentials will be calculated using the observation well closest to an extractionwell following the equation below:

O&M Manual A-15Motor Wheel Disposal SiteSharp and Associates, Inc.OH. doc/5104-16/5/2/9 7

D = (DWL-PWL) / Q

D = differential, ft/gpmDWL = water level elevation in nearby observation well, ft. above MSLPWL = water level elevation in pumping well, ft. above MSLQ = pumping rate, gpm

Comparing specific capacity and observation well differentials over time will indicate when interceptor wellredevelopment is warranted. Additionally, graphical plots of specific capacity versus time will be used totrace well efficiencies in conjunction with interceptor well/observation well differential results.

Since the interceptor well network is a dynamic system, individual well pumping rates are subject to changeover time based on changes in the saturated thickness of the aquifer, degradation of well efficiencies, andsystem improvements. Therefore changes in design pumping rates will also be evaluated annually based onground water table maps and capture zone analysis. The results will be reported as part of the monthlyreports.

Any significant repairs or changes to the extraction well system will be discussed in the annual evaluation.This maintenance plan will be revised as necessary to accommodate those repairs or changes.

5.2 VERIFICATION OF CONTAMINATION REMOVAL

The air stripper is rated to remove VOCs to below the required discharge standards. In order to verifythe effectiveness of contaminant removal, the influent concentrations of the extracted groundwater shallbe checked against the effluent concentrations from the treatment system. By converting the influentconcentrations and the effluent concentrations to mass values and taking the difference shall reveal themass of contaminants being emitted from the air stripper stack. This shall enable the operator to ensurethe air stripper emissions are not exceeding applicable air quality standards.

5.3 SYSTEM LOGIC

The Glacial Aquifer Groundwater Remediation System is controlled by a Alien Bradley Program LogicController (PLC). The PLC controls a variety of fail safes to guard against contaminant releases in theevent of system failure. For a complete description of the PLC controls and fail safes refer toAttachment E.

In the event of system shutdown, the PRPs and all applicable agencies shall receive verbal notificationwithin 72 hours and written notification within 7 days. The event shall also be detailed in the monthlyreports.

5.4 ADDITIONAL RESOURCES

In order to minimize downtime due to equipment failure, an inventory of replacement parts shall bemaintained at the MWDS. Available replacement parts include at least one replacement pump andmotor of each type used in the extraction wells, spare transducers, and a stock of miscellaneous partssuch as fuses, low flow alarms and pump controls. This inventory allows equipment repair of minorO&M Manual ^. J gMotor Wheel Disposal SiteSharp and Associates, Inc.OM.doc/5104-16/5/2/97

problems within a reasonable time frame. To assist in operational failure evaluation, a trouble shootingguide is presented in Attachment C.

5.5 PETITIONS

The U.S. EPA may be petitioned after the system has been operating for a minimum of ten years andappropriate adjustments have been made to improve contaminant removal, to waive compliancethe Ground Water Cleanup Standards set forth upon initial startup of the system. The basis for thepetition is set forth in the Consent Decree, United States of America vs. Motor Wheel Corporation , , - (Section 12-b. '

The U.S. EPA may be petitioned after the system has been operating for a minimum of ten years andappropriate adjustments have been made to improve contaminant removal, to terminate groundwaterextraction and treatment. The PRPs must demonstrate the groundwater cleanup standards have beenmet throughout the entire area of contamination or that there is no longer a risk at the site. Thisdemonstration shall cover 4 consecutive semi-annual monitoring periods during which none of diecontaminated groundwater levels in any of the monitoring wells may exceed any groundwater cleanupstandard.

Upon completion of the groundwater restoration and/or petitioned shutdown of the remediation system,groundwater monitoring indicates the concentrations of contaminants have increased above the aquifercleanup standards the groundwater extraction and treatment system shall be reactivated.

5.6 CORRECTIVE ACTIONS

In me event cleanup standards and/or hydraulic capture is not being attained, the appropriate agenciesand parties shall be kept informed of the adjustments made to the system to correct the problem throughtelephone conversations and the monthly reports. All adjustments performed on the remediation systemshall be monitored for performance and results recorded in the monthly reports.

If the potentiometric surface maps and the analysis of hydraulic capture indicates that the zones ofcapture are insufficient to meet the remedial objectives of this program, the efficiency data from thepumping well(s) involved will be examined and a determination made as to the probable cause.Corrective actions may include cleaning, repairing, or replacing downhole equipment; or rehabilitatingthe well. If rehabilitation is warranted the work will be performed within three months of the date thatthe problem was identified.

The treatment system is equipped with a recycle line. In the event the NPDES discharge limits are notbeing met, the recycle line shall be utilized to ensure discharge criteria are met. The control of therecycle line is described in Section 2.3 line description 50-51 in Attachment E.

Leaks within the treatment building will be detected by a water sensor. This water sensor will beconnected to the system controls and shut down the system and also notify operations personnel of thesituation. If any significant leaks are detected within the system, the effected equipment will beshutdown until properly repaired.

O&M Manual A-17Motor Whtel Disposal SiteSharp and Associates, Inc.OM.doc/5104-16/1/2/97

5.7 GROUNDWATER REMEDIATION SYSTEM ANALYTICAL PARAMETERS

Water discharged to the Grand River is regulated by Michigan Act 245 of the Public Acts of 1929, asamended, Part 4, Rule 57 Water Quality Standards (Rule 57). Rule 57 establishes surface waterdischarge criteria for the target VOCs among other parameters using Water Quality Based EffluentLimitations (WQBELs), Treatment Technology Based Effluent Limitations (TTBELs), andantidegradation criteria. Discharge standards for each of the VOCs are no more stringent than thedrinking water maximum contaminant levels (MCLs). Modeling of the ammonia discharge wasperformed (FTC&H, Final Additional Studies/Predesign Report, 1996) using the Streeter-PhelpsDissolved Oxygen Model to predict water quality effects. This modeling indicates that the discharge ofammonia to the Grand River will not cause a degradation of water quality and subsequently notreatment is required except during summer months. During the summer months, the dischargeammonia has been determined by MDEQ to cause a degradation of the water quality. This results fronv-^the low flow and higher temperature of the Grand River. The PRP group is currently reviewingtreatment technologies for the removal of ammonia during the summer months.

The emission limitation of VOCs from the air stripper is based on the air toxic regulations developedby the MDEQ Air Pollution Control Commission, as defined under Administrative Rule No.R336.1230. This ruling states that the VOC concentration in the air discharge must not exceed the"maximum allowable emission rate based on the application of best available control technology for'toxins (T-BACT)" and the "initial threshold screening level" (ITSL) or the initial risk screening level(IRSL) or both." The IRSL takes precedence when the compounds are suspected carcinogens.

Since hazardous substances shall remain on Site, ground water monitoring shall at least meet therequirements of Michigan Hazardous Waste Management Act, 1979 P.A. 64, as amended. Rule299.9612, Ground Water Monitoring and Rule 299.9613, Closure and Post closure.

The treatment system effluent will be sampled on a regular basis in order to ensure that the waterdischarged to the Grand River will meet the prescribed NPDES permit limits. The draft NPDESpermit is located in Appendix P of the Design Report. Based upon this information, the system will besampled for chlorinated solvents, benzene, ethylbenzene, toluene, xylenes, naphthalene, ammonia, totaldissolved solids, pH, and dissolved oxygen.

1.0 INTRODUCTION

The Motor Wheel Disposal Site PRP Group contracted with Sharp & Associates, Inc. (SHARP) toprepare the Comprehensive Groundwater Monitoring Plan for the Motor Wheel Disposal Site (MWDS)in Lansing, Michigan. This Comprehensive Groundwater Monitoring Plan addresses sampling andanalysis requirements for groundwater contained in the Perched Aquifer, Glacial Aquifer, and theSaginaw Aquifer wells in the vicinity of the MWDS.

This plan follows requirements specified in the Administrative Order of Consent (AOC) between theUnited States of America, the State of Michigan, and MWDS PRP Group which was signed on June 26,1987. This plan follows the EPA Guidance on Remedial Actions for Contaminated Ground Water atSuperfund Sites.

1.1 SITE HISTORY

The MWDS site is a 24-acre property located at 1401 Lake Lansing Road in the northeastern portion ofthe City of Lansing, Michigan. The site is situated within the NE 1/4 of the SW 1/4 of Section 3 inLansing Township (T4N, R2W), Ingham County, Michigan (Figure 1, Site Location Map). TheMWDS site and the surrounding properties are further illustrated on Figure 2, the Site Map. This latterfigure shows the spatial relationships of the MWDS, the current property ownership, and the site'srelationships to adjacent properties.

Historically, the MWDS was used by the Motor Wheel Corporation as a disposal site for industrialwastes from 1938 until approximately 1978 (U.S. EPA, 1991). The types of wastes disposed at theMWDS included solid and liquid industrial wastes such as paints, solvents, liquid acids, caustics, andsludges. These waste products were disposed of on the property in the forms of: tanks, barrels,seepage ponds and open fill operations (U.S. EPA, 1991).

A minimum of three cleanup operations/actions were conducted on the site between 1970 and 1982.The result of these actions was the excavation and offsite disposal of excavated waste materials(Hunter/Keck Environmental Services(Hunter/Keck), 1990). In 1970, the Michigan Department ofNatural Resources (MDNR) requested that the Motor Wheel Corporation remove solid wastes, paintsludges, and oils from seepage pond areas. Some of the excavated materials generated during thisoperation were disposed of offsite, and the former seepage pond areas were backfilled (U.S. EPA,1991). During December 1982, three 10,000 gallon tanks, their contents and associated contaminatedsoil and fill materials were removed and disposed offsite. Concurrent with the tank removaloperations, an unknown quantity of drums were also removed from the MWDS and disposed offsite(U.S. EPA, 1991).

MSV Associates acquired the MWDS property in 1978, and began an open pit sand and gravelquarrying operation. During their quarrying, buried wastes were encountered and exposed. Thesewastes were subsequently excavated and stockpiled on the western part of the site, and later partiallycovered with clay (U.S. EPA, 1991).

The MWDS was placed on the National Priorities List (NPL) on October 4, 1986 (50 FR 41015). TheMotor Wheel Corporation, W.R. Grace & Co., and the Goodyear Tire & Rubber Company signed anAdministrative Order of Consent (AOC) agreeing to conduct a Remedial Investigation (RI) and aFeasibility Study (FS) at the MWDS on June 26, 1987 (U.S. EPA, 1991).

As a result of the RI/FS investigations, the MWDS was divided into two operable units. One operableunit consists of the landfill mass and the on-site and off-site groundwater contamination present withinthe perched and Glacial Aquifers. The second operable unit is the Saginaw Sandstone Aquifer.

MSV Associates discontinued the sand and gravel quarrying operations at the site in 1987. MSVremains the property owner, although the site is inactive.

1.2 SITE INVESTIGATION ACTIVITIES

In accordance with the June 26, 1987 AOC Agreement, an RI for the MWDS was conducted byHunter/Keck. The results of the Hunter/Keck RI investigation were reported on February 8, 1990, intheir report titled Remedial Investigation Report, Motor Wheel Disposal Site. Lansing, Michigan. A FSwas conducted by ENSR Consulting and Engineering (ENSR). The FS report was published in May1991 by ENSR in their report titled Final Draft, Feasibility Study Report for Motor Wheel DisposalSite. On September 30, 1991, the Declaration for the Record of Decision (ROD) for the MWDS wassigned by US EPA.

In April 1992, Fishbeck, Thompson, Carr and Huber (FTC&H) issued the Saginaw AquiferInvestigation Report for the Motor Wheel Disposal Site, Lansing Michigan, to summarize theirinvestigations of the deeper and municipally developed Saginaw groundwater aquifer. Additionalinvestigations of the MWDS and both the glacial and Saginaw Aquifers were performed by FTC&H.Their activities and a predesign for remediation of Operable Unit 1 (the MWDS and the GlacialAquifer) were published in Final Additional Studies/Predesign Report, 1996. Subsequent to thepublication of the FTC&H field investigations, Sharp and Associates. Inc. (SHARP) was retained bythe MWDS Potentially Responsible Parties (PRP) Group to further the investigation of the SaginawAquifer. SHARP submitted the Saginaw Formation Aquifer Investigation Work Plan Addendum No. Ifor the Motor Wheel Disposal Site, Lansing, Michigan, was submitted by SHARP on April 13, 1995.Subsequent revisions to this work plan were submitted on August 11, 1995 and November 11, 1995.The work plan and subsequent revisions were approved by the U.S. Environmental Protection Agency(EPA) Region V and the Michigan Department of Environmental Quality (MDEQ). In November 1996,SHARP issued the Interim Report for The Investigation of the Saginaw Aquifer at the Motor WheelDisposal Site. In addition to the Saginaw Aquifer work plan and its revisions, SHARP has continuedwork on the Operable Unit remedial system design as published in: The 30% Design Report for theGlacial Aquifer Groundwater Remediation System and Engineered Landfill Closure, July 1996 and theDraft Final Design submitted on December 23, 1996.

1.3 RECORD OF DECISION (ROD)

The ROD for the first operable unit at the MWDS was signed on September 30, 1991. The firstoperable unit includes the waste mass and the groundwater contamination in the perched and GlacialAquifers at the MWDS. The groundwater contaminants of concern, as determined by theHunter/Keck, 1990 RI, and the risk and toxicity assessments include the following volatile organic

compounds (VOCs):

1,1 Dichloroethene (1,1-DCE) Chloromethane1,2-Dichloroethane (1,2-DCA) Ethylbenzene1,2-Dichloroethene (1,2-DCE) Methyl Chloride2-Butanone Naphthalene2-Hexanone Tetrachloroethene (PCE)4-Methyl-2-pentanone Trichloroethene (TCE)Benzene TolueneChloroethane Vinyl Chloride (VC)Chloroform Xylenes, Total

The semi-volatile organic compound (SVOC) contaminants of concern included bis(2-ethylhexyl)phthalate and 2,4,5-trichlorophenol. Inorganic contaminants of concern included ammonia,chloride, fluoride, iron, lead, nitrate, sulfate, and zinc

The ROD cleanup criteria for these respective constituents are presented in Table 1. In June 1995,Michigan amended the Michigan Environmental Response Act, Act No. 307 of 1982, and incorporatedthe amended Act into the Natural Resources and Environmental Protection Act, Act No. 451 of 1994.This new legislation included changes to the cleanup standards that had been previously cited asApplicable or Relevant and Appropriate Requirements (ARARs) in the ROD.

The September 30, 1991 ROD did not specifically address the Saginaw Aquifer, its investigation, orcontaminants of concern, nor did it specify cleanup standards. The Saginaw investigative effortsconducted thus far have identified three constituents of concern within the Saginaw Aquifer. Theyinclude ammonia, fluoride, and vinyl chloride. As a point of departure for this RI, SHARP used thecleanup standards assigned to the glacial and perched water aquifers as described under "Clean-UpStandards" listed on page 6 of the Final Scope of Work for the Remedial Design, Motor Wheel DisposalSite, Ingham County, Michigan, May 12, 1992, and on Table 10 of the ROD (Table 1 of thisdocument). The clean-up standards noted by these documents for Saginaw Aquifer constituents ofconcern are as follows:

• ammonia 34,000 micrograms per liter (ng/1)• fluoride 2,000 micrograms per liter (ng/1)• vinyl chloride 1 microgram per liter (|o.g/l)

However, subsequent to the Operable Unit 1 ROD and the 1992 Final Scope of Work,, the clean-upstandards for vinyl chloride and ammonia have been revised (Ref. Natural Resources andEnvironmental Protection Act, Act No. 451 of 1994, Part 201, the Safe Drinking Water Act, andMaximum Concentration Levels (MCLs)). Current MCL values and this investigation's recommendedclean-up values for these constituents are as follows:

• ammonia There is no MCL for ammonia.• nitrate (as N) 10,000 micrograms per liter• nitrite (as N) 1,000 micrograms per liter• fluoride 4,000 micrograms per liter. It should be noted that the fluoride

standard is currently under review.• vinyl chloride 2 micrograms per liter

1.4 SURROUNDING LAND USE

Current land use adjacent to, and surrounding the MWDS includes light and heavy industrial properties,commercial businesses, a sanitary landfill, a demolition debris/clean fill landfill, and residential singleand multi-family housing areas.

1.5 GEOLOGY/HYDROGEOLOGY

The MWDS is located within the south-central portion of the Michigan Basin physiographic province.Geologically, the topography of the area is relatively flat to gently rolling and reflects the erosionaland depositional processes associated with multiple periods of Pleistocene glaciation. The surfacesediments of the area are largely reworked recent materials which largely reflect the overprint ofurban, commercial, and industrial activities. The native surface and near surface sediments of thearea consist of mature soils and unconsolidated sediments which have been developed from multipleglacial parent materials. Regionally, these uppermost Recent and Late-Pleistocene sediments havebeen unconformably deposited on Pennsylvanian aged bedrock strata (Westjohn et al., 1994).

1.6 POTENTIAL CONTAMINANT SOURCES AND TRANSPORT

The contamination present within the Perched and Glacial Aquifers at the MWDS is attributable to thehistoric dumping, landfilling and quarrying operations that have occurred at the site. The contaminationpresent in the downgradient plumes of the Glacial Aquifer related to the MWDS is a source ofcontamination to the underlying Saginaw Aquifer in this region. The downward flow of contaminantsfrom the glacial into the Saginaw occurs where the erosion of the upper Pennsylvanian black shale,coupled with the reduction in quality of the basal till unit, create "windows" where the downwardmovement of Glacial Aquifer waters can occur. Specifically in this area of investigation, the"window" present south and west of MW-68 serves as a leakage area where the contaminated,relatively high velocity, south-flowing Glacial Aquifer waters can enter and mix with the relativelyslower velocity, northwesterly flowing waters of the Saginaw.

2.0 OBJECTIVES

The primary objectives of this Comprehensive Groundwater Monitoring Plan for the MWDS include:

• The collection of water level data to monitor the groundwater extraction systems to showhydraulic capture of contaminant concentrations in excess of the cleanup goals;

• The collection of water chemical data to monitor the progress of the groundwater cleanup;

• The preparation of a consolidated plan for monitoring the contaminant plumes present within thePerched, Glacial, and Saginaw Aquifers; and

• The collection of effluent concentrations from die treatment plants to verify compliance withdischarge limits.

The numerical cleanup goals for the Perched and Glacial Aquifers are shown on Table 1 . The currentcleanup goals assigned to the Saginaw aquifer are as follows:

Ammonia 34,000 u,g/LComprehensive Groundwater Monitoring and Sampling PlanMotor Wheel Disposal SitePrepared by Sharp and Associates, Inc.AttachF.DbOrev. 4/30/97

• Fluoride 4,000• Nitrate 10,000• Nitrite 1,000 ug/L• Vinyl Chloride 2 jig/L

However, the cleanup goal for ammonia is presently under review by MDEQ. The PRP group hasrecommended to the Agency that the ammonia constituent be removed as there is no MCL for ammonia,and nitrate and nitrite be substituted.

3.0 RATIONALE FOR SELECTION OF SAMPLING LOCATIONS AND FREQUENCY

This section describes the rationale for the selection of wells to be sampled and the frequency ofsampling. The Perched, Glacial and Saginaw Aquifer wells included in this comprehensive monitoringprogram are intended to monitor the following:

• the effectiveness of extraction on the aquifers in development of a zone of capture for thecontaminated groundwater;

• the reduction of the concentrations of the contaminants of concern created by the pumping andtreatment process; and

• the effectiveness of the pump and treat process to control the migration of the contaminantplumes.

3.1 PERCHED, GLACIAL AND SAGINAW AQUIFER PLUME SAMPLING PLAN

Groundwater samples will be collected from monitoring wells and extraction wells located around theperimeter, downgradient, and within the contaminant plumes. The groundwater samples will be fieldmonitored for pH, temperature, conductivity, and analyzed for VOCs, selected semivolatiles, ammonia,and fluoride. Groundwater levels will be measured in the extraction, monitoring and compliancemonitoring wells.

The number of measurements and samples to be collected has been determined based upon the datarequired to monitor the Perched, Glacial and Saginaw Aquifers, proper plant operation, and theeffectiveness of the pumping and treatment system. Groundwater levels will be manually measuredaccording to the schedule shown in Table 3. These measurements will be used to evaluate groundwaterelevation changes caused by pumping. For the first month, the groundwater levels in the wells equippedwith transducers will be programmed to collect levels at least 4 times per day and downloaded from theTroll transducers on a weekly basis.

Following the initial "shake-down" of the system (3 months), the data collection frequency of wells withtransducers will increase to one per day (downloaded monthly), and then eventually to greatermonitoring intervals. The Troll transducers will be programmed so that unusual changes in water levelsdetected at a regular sampling interval will "trigger" increased frequency of measurements to helpdetermine the cause of the change and it's effects with respect to the extraction system.

The frequency of sampling the Perched and Glacial Aquifer wells will be initially on a quarterly basis,with the Saginaw Aquifer wells on a semi-annual basis until the plume delineation is completed and aremedy selected. A total of forty-four (44) Perched, Glacial and Saginaw Aquifers wells will beComprehensive Groundwater Monitoring and Sampling PlanMotor Wheel Disposal SitePrepared by Sharp and Associates. Inc.AttachF DOCIrn. 41)0/97

sampled as part of the quarterly sampling program (5 wells in the Perched Aquifer, 31 wells in theGlacial Aquifer, and 8 wells in the Saginaw Aquifer).

Table 2 lists the Perched, Glacial and Saginaw Aquifers wells which will be sampled under this MWDSMonitoring Plan. Table 3 lists the wells to be sampled for analytical parameters and water levelmeasurements. Figures 3 and 4 illustrate the well locations for the glacial aquifer for water levelmeasurements and analytical sampling, respectively. Similarly, Figures 5 and 6 illustrate the locationsfor water levels and analytical sampling for the Saginaw Aquifer. These figures will be revised toinclude the new wells after installation.

4.0 RATIONALE FOR ANALYTICAL PARAMETERS

The comprehensive groundwater monitoring plan for the Glacial Aquifer has been pared down to the listof analytes that have been historically detected. These analytes include ammonia, fluoride, and vinylchloride. For the Saginaw Aquifer, only Ammonia and vinyl chloride have been detected. Therefore,fluoride has been dropped as a parameter for that aquifer. Nitrate has been analyzed for in samplesfrom wells in the Glacial Aquifer and the Saginaw Aquifer and has not been detected to date (with theexception of two on-site wells completed in the landfill). For the analysis of wells completed in thePerched Aquifer, nitrate and the chemicals required for the NPEDS permit have been added to the suite(i.e., analyze for ammonia, fluoride, chlorinated solvents, BTEX, naphthalene, and nitrate. CurrentlyMDEQ is evaluating the PRP group's proposal to drop the ammonia as a clean-up criteria and substitutenitrate. Pending the outcome, the sampling suite will be altered.

At die conclusion of remediation for the Perched, Glacial and Saginaw Aquifers, a final comprehensiveround of samples will be collected from the entire well network. For that sampling, methods will beselected to assure appropriate testing for all analytes in the 1991 ROD.

See Tables 2 and 3 for the selected sampling frequencies and corresponding analyses for the Perched,Glacial and Saginaw Aquifers. Interim sampling methods, preservatives, holding times and containerrequirements are presented in Table 4.

5.0 FIELD METHODS AND SAMPLING PROCEDURES

The groundwater monitoring program at the MWDS includes the measurement of groundwater levels inthe designated wells, field measurements, and analysis of groundwater samples by an analyticallaboratory. The water level data is used for determining the flow direction of groundwater at the site.Field measurement data is collected during well purging to ensure a representative analytical sample iscollected. The analytical samples are collected to determine the progress of the remediation efforts at thesite.

The wells selected for water level measurements and sampling and analyses are shown in Tables 2 and3. Table 4 provides the relevant information pertaining to analytes, analytical methods, preservation,holding times, sample volumes, and required quantitation limits.

5.1 WATER LEVEL MEASUREMENTS

Upon arrival at each well, the sampler will observe and record the condition of the surface seal and wellprotector, including the lock. Any evidence of vandalism, insect/rodent intrusion or damage by vehiclesor other activities will be noted and corrected. If the wells are fitted with airtight caps they will beopened and allowed to equilibrate to atmospheric pressure for 24 hours prior to the time water levelmeasurements are taken.

These observations will be recorded on field sampling sheets or in a bound field book. Records shouldinclude the names of the sampler(s), date and time of activities, list of equipment used as well as otherpertinent data.

Prior to sampling each well, a measurement of the groundwater level below the top of the well casingwill be obtained. Water levels will be measured from the top of the measuring tube (measuring point) atthe permanently marked, surveyed point at the north side of the well casing, not from the top of the steelprotective casing.. Three successive measurements will be taken in each monitoring or observation wellwith an electric water level indicator (Solinst or equivalent) and recorded to the nearest 0.01 foot. Thewater level indicator will be decontaminated with distilled/de-ionized water between each well. Thegroundwater levels in the monitoring wells, compliance wells, observation wells and extraction wellswill be measured with an electronic water level indicator and/or the dedicated pressure transducer.Water level measurements will be collected according to the schedule presented in Table 3. Water levelmeasurements will also be recorded in the process of sampling for analytical parameters (Table 4). Thewater levels will be measured to the nearest 0.01 foot and recorded. Prior to inserting the water levelindicator into each well, the probe will be decontaminated by rinsing with distilled/deionized water.

Groundwater elevations will be calculated based on the reference point elevations listed in Table 2, lessthe measured depths to groundwater.

5.2 SAMPLE COLLECTION PROCEDURES

Sample collection and analysis for this project shall be conducted in accordance with applicable US EPAmethods and procedures.

Groundwater samples taken from the groundwater extraction wells, compliance wells, observation wells,and selected monitoring wells will be analyzed for selected VOCs, and ammonia, fluoride, and nitrate.Comprehensive Croundwater Monitoring and Sampling PlanMotor Wheel Disposal SitePrepared by Sharp and Associates. Inc.AnadiF.DOCJrev. 4/30/97

13

Groundwater samples will be collected according to the schedule presented in Tables 3. The sampleswill be collected utilizing either dedicated or decontaminated submersible pumps capable of pumping aminimum of one gallon per minute (gpm), bailers fabricated of stainless steel or disposable PVC, ordedicated extraction pumps. Bailer rope will consist of new or dedicated braided polypropylene rope.Decontamination of sampling equipment is discussed in Section 5.3.

Sampling will generally proceed from the lowest to highest expected contaminant concentrations basedon previous analytical results.

5.2.1 Well Purging and Stabilization Testing

Prior to sample collection, static water level measurements will be taken at each well using theprocedures described in Section 5.1. The static water level will be measured to the nearest 0.01 foot andrecorded on the field sampling sheets and in the field logbook. The height of the water column will becalculated by subtracting the static water level from the total depth of each well (see Table 6). The wellvolume will be calculated by multiplying the water column height by the cross sectional area of the well.

At least three well volumes of water will be removed from each well with a decontaminated stainlesssteel or new disposable PVC bailer, sampling pump or a dedicated extraction pump. The bailer ordownhole pumps will be used to purge and sample the two-inch diameter wells. New or dedicatedpolypropylene rope will be used to raise and lower the bailer during sampling and will be discarded afteruse or dedicated to the well. The volume of water purged (bailed wells) or the time and rate of pumpingwill be recorded on the field sampling sheets and in the field logbook. When the well is purged, thepumping or bailing rate will be set so that the water level in the well will not fall below the top of thescreen.

Stabilization tests will be performed during the purging and prior to the sampling of each well. Thepurpose of the stabilization test is to ensure that a sufficient volume of water has been removed from awell to allow representative sampling of the formation water.

During the purging of each well, the parameters representing specific conductance, pH and, temperaturewill be measured in the field. The parameters will be measured before purging is initiated, after eachpurged well volume, and after sampling is completed. These procedures will be continued until at leastthree successive readings of conductivity, pH and temperature are established within 10 percent. Allreadings will be recorded on the field sampling sheets or in the field notebook. The visual condition ofthe groundwater will also be recorded on the field sampling sheets or in the field book.

5.2.2 Sample Collection

Samples will be collected after the well has been adequately purged as defined by Section 5.2.1. Thesample will be collected utilizing either a stainless steel or new disposable PVC bailer, sampling pumpor submersible extraction pump or dedicated extraction pump. Wells that are to be sampled quarterly ormore frequently will be equipped with dedicated pumps. The bailer used for purging will be used tocollect the samples. Bailers equipped with bottom emptying devices will be used to minimize loss ofvolatiles. Containers will be filled in such a manner as to ensure minimal aeration of the sample.Sample collection for analysis of VOCs will be followed by collection of samples for inorganic analyses.

Samples from dedicated submersible pumps will be collected from Teflon tubing attached to a "tee"connected to the discharge end of pump. Sample flow rates will follow the USEPA's low flow protocolsComprehensive Crounttwater Monitoring and Sampling PlanMotor Wheel Disposal SitePrepared 4y Sharp and Associates. Inc.MacnF.DOCIm. 4/3CU97

(100 to 500 ml/minute) for filling the VGA vials and will not exceed 1 gpm during the remainder ofsample collection. Sample containers will be filled to overflowing and then capped to ensure zeroheadspace. Table 4 lists the sample containers.

All samples will be appropriately labeled and all sampling activities recorded on field sampling sheets orin the field logbook. Groundwater samples will be stored immediately after collection in coolers at 4°Cfor transport/shipment to the laboratory. All sampling equipment will be decontaminated after eachsample collection is complete and prior to sampling the next well. Decontamination procedures arepresented in more detail in Section 5.3.

Sampling personnel will wear gloves during all stages of sample collection, handling anddecontamination. Clean or new inner gloves will be worn at each new sampling location. Thedecontaminated equipment will be covered with plastic sheeting, as necessary, to prevent contaminationwhen not in use.

The instruments for collection of field measurements (including temperature, pH and conductivity) willbe calibrated in accordance with the manufacturer's instructions for each unit.

5.2.3 Quality Assurance/Quality Control Samples

The quality control (QC) samples include equipment rinseate blanks, trip blanks, duplicate samples, andlaboratory QC samples. The QC samples are collected at the following frequencies:

• Equipment Rinseate Blank - one per day for each day that non-dedicated equipment is used;collected after the decontamination of equipment used at the highest concentration well (ifknown) and analyzed for all parameters of interest.

• Trip Blank - one per day for sampling days that involve volatile organics; container is suppliedby the laboratory and accompanies the shipped samples.

• Duplicate - one per 20 samples collected; collected at high concentration wells (if known) usingdifferent wells for different sampling rounds; submitted blind (without identification of the well)to the laboratory.

The method for collecting duplicate samples is the same for collecting regular samples. Duplicatesamples should be collected from those wells with suspected contamination or from those wells with thehighest known concentrations of VOCs. Water samples for VOC analysis will be collected directly intothe sample container from the bailer or sampling valve, in order to minimize loss of VOCs. Duplicatesamples will be collected immediately after the regular sample is collected and will be assigned a uniquenumber for submittal to the laboratory as a blind sample.

Equipment rinseate blanks will be collected by pouring distilled/deionized water over decontaminatednon-dedicated sampling equipment. This sample will be collected once per sampling day after thedecontamination of the sampling equipment used for sampling the well with the highest levels of knownVOCs.

Blanks and duplicates will be handled in the same way as the regular samples which they accompany.These samples will be submitted to the laboratory as blind samples.

5.3 EQUIPMENT DECONTAMINATION

Decontamination is an important process that is required to prevent the spread of contamination and toprotect the health and safety of on-site personnel. The procedures outlined here are designed to preventthe spread of contamination and possible cross contamination of samples.

All non-dedicated equipment that comes in contact with potentially contaminated materials will bedecontaminated prior to being used. Initially the decontamination will serve to remove any dust or dirtaccumulated during transit to the site or possible residual contamination from previous use. Thereafter,the decontamination will be to remove any residual contamination from the preceding sampling.

All equipment will be disassembled to the extent practicable prior to decontamination. Since organicsare of primary contaminant of concern, decontamination will consist of the following:

• Wash with a non-phosphate based detergent• Rinse with potable water• Double rinse with distilled/deionized water• Final rinse with HPLC grade water

The equipment will then be allowed to air dry and will be wrapped in plastic sheeting until needed.

For wells infrequently sampled by using non-dedicated pumps, the procedures for these type wells willinclude equipment decontamination prior to sampling. The discharge tubing from the sampling pump ison a reel and is an integral part of the sampling pump system, hence will not be discarded betweensampling events. The discharge tubing will be cleaned by pumping non-phosphate, mildly soapy waterthrough the assembly, followed by a complete flush using potable water. The entire external assembly(including the discharge tubing) is washed and decontaminated per the protocol. The equipment rinsesamples are collected from the discharge side of the pump and tubing to document complete cleaning ofthe equipment.

5.4 DISPOSAL OF CONTAMINATED MATERIAL

All purge water from well sampling activities will be contained in an on-site potable water tank anddisposed of by treatment through the treatment plant facilities. Other contaminated material will becontainerized, labeled, and disposed of at an off-site facility in accordance with applicable regulations.

5.5 SAMPLE DOCUMENTATION AND SHIPMENT

Each sample shipment will be subjected to a tracking program. This program is designed to ensure theintegrity of each sample from the time of collection until the samples are delivered to the laboratory foranalysis. The program consists of:

• Sample labels• Field logbook• Chain-of-Custody Forms

Comprehensive Groundwater Monitoring and Sampling PlanHoar What Disposal SitePnpand by Sharp and Associates, Inc.AttacnF.DOC/m 4/30/97

16

5.5.1 Sample Labels

The sample labels will be used to prevent mis-identification of the samples. Each sample label will befilled out in the field by the sampling team, using indelible (water-proof) ink on prepared sample labels.The label will then be firmly affixed to the sample container.

The sample label will include the following information:

• Client Name• Project Number• Sample Identification Number• Initials of person collecting the sample• Date and time of sample collection• Analysis to be performed on the sample• Number of sample containers collected for the location• Preservative used (if any)

The sample container's cap will also be labeled with the sample identification number.

5.5.2 Field Logbook

Each sample will be noted on the field sampling sheets or in the field logbook at the time of collection.The field logbook will be a bound book with numbered pages. Each day's entry will be signed anddated by the individual making the entry. The sampling form or field logbook will contain the followinginformation:

• Identification of the sample location• Purge rate and method• Collection method and rate as applicable• Sampling sequence• Sample identification (must match sample tag)• Notation of QA/QC sample type and corresponding sample identification• Type of container• Preservatives used• Physical description of sample• Field observations of sampling event• Name of sample collector(s)• Climatic conditions during sampling

5.5.3 Chain-of-Custody Record

In order to establish the documentation necessary to trace sample possession from me time of collection,a chain-of-custody record will be prepared. The chain-of-custody record will accompany the samplesfrom the time of collection until they are delivered to the laboratory for analysis. The chain-of-custodyrecord will identify the following:

• Sample number• Date and time of collection• Sample type

Comprehensive Groundwater Monitoring and Sampling PlanMotor Wheel Disposal SitePrepared try Sharp and Associates, Inc.AtuchF.DOGrrr. 4/30/97

17

• Number of containers• Parameters requested for analysis• Signature of person(s) involved in chain of possession• Date and time of possession transfer• Method of sample transport.

5.5.4 Sample Custody Seals

The samples can be either delivered by the sampling team to the laboratory, picked up at the site by alaboratory courier, or sent to the laboratory via an express/overnight delivery service. The purpose of thecustody seals is to ensure that the samples are not tampered with in transit from the sampling team to thelaboratory.

Sample custody seals will be placed on each sample to ensure that the samples have not been tamperedwith during their shipment to the laboratory. If the samples are shipped to the laboratory via anexpress/overnight delivery service, the shipping container enclosing the samples will be sealed with twocustody seals, secured with clear plastic tape, before being released from the sampler's custody. Thelaboratory sample custodian will inspect all custody seals and notify the sampler if any of them are brokenon either the cooler or sampling containers. Resampling may be necessary if the custody seals are broken.The custody seal will be signed and dated, by the person responsible for packaging, prior to being placed

on the shipping container.

SECTION 1 INTRODUCTION

The Motor Wheel Disposal Site Group has contracted with Sharp and Associates, Inc. (SHARP), HWHEngineers (HWH), and Fishbeck, Thompson, Carr, & Huber (FTC&H) to prepare the RemedialAction Plan for the Motor Wheel Disposal Site (MWDS). This Remedial Action Plan covers theOrganization and the Project Schedule for the installation of the landfill cap and the Glacial Aquifergroundwater remediation system. This document is being prepared in order to comply with the Recordof Decision (ROD) (September, 1991).

1.1 GENERAL BACKGROUND AND SITE HISTORY

The MWDS is a 24-acre property located at 1401 Lake Lansing Road on the northeast edge of the Cityof Lansing, Michigan. The site lies in the NE 1/4 of the SW 1/4 of Section 3 in Lansing Township(T4N, R2W), Ingham County, Michigan. The property was used by Motor Wheel Corporation as adisposal site for industrial wastes from 1938 until about 1978 (US EPA, 1991). The types of disposedwastes included solid and liquid industrial wastes, such as paints, solvents, liquid acids, caustics, andsludges. Wastes were disposed of on the property in tanks, barrels, seepage ponds, and open filloperations (US EPA, 1991).

Between 1970 and 1982, at least three cleanup actions, which resulted in the excavation and off sitedisposal of waste materials, were initiated (Hunter/Keck Environmental Services [Hunter/Keck], 1990).In 1970, the MDNR requested that the Motor Wheel Corporation remove solid wastes, paint sludges,and oils from seepage pond areas for disposal offsite. Some of the excavated materials were disposedoff site and the former pond areas were backfilled (US EPA, 1991). Three 10,000-gallon tanks, theircontents and contaminated soil, and fill surrounding the tanks were removed and disposed offsite inDecember 1982. An unknown number of drums were also disposed of offsite at this time (US EPA,1991).

In 1978, MSV Associates acquired the property and began open-pit sand and gravel mining. Themining operations exposed some of the buried industrial wastes. The exposed materials weresubsequently excavated, stockpiled on the western pan of the site, and covered with clay (US EPA,1991).

The site was placed on the National Priorities List on October 4, 1986 (50 FR 41015). On June 26,1987, Motor Wheel Corporation, W.R. Grace & Co. (Grace), and The Goodyear Tire & RubberCompany signed an AOC agreeing to conduct a Remedial Investigation (RI) and Feasibility Study (FS)at the MWDS (US EPA, 1991). Following USEPA's ROD in September 1991; Goodyear, Grace,Textron, Inc., and the Lansing Board of Water and Light entered into a consent agreement to conductthe Remedial Design.

Site gravel/sand mining operations were discontinued in 1987. MSV Associates is the current owner ofthe property. However, the site is presently inactive (US EPA, 1991).

RAP.DOC D-lSharp and Associates. Inc.

1.2 PREVIOUS STUDIES

In accordance with the AOC, an RI for the site was conducted by Hunter/Keck. The results of the RIwere summarized in a report dated February 8, 1990, and titled, Remedial Investigation Report, MotorWheel Disposal Site, Lansing, Michigan. An FS was conducted by ENSR Consulting and Engineering(ENSR). The results of this study were summarized in a report titled, Final Draft, Feasibility StudyReport for Motor Wheel Disposal Site, dated May 1991. The Declaration for the Record of Decision(ROD) was signed by the US EPA on September 30, 1991. An investigation of the Saginaw aquifer atthe MWDS was conducted by Fishbeck, Thompson, Carr an Huber (FTC&H), and the resultssummarized in a report titled, Saginaw Aquifer Investigation Report for the Motor Wheel Disposal Site,Lansing, Michigan, dated April 1992. Additional investigations were performed and a predesign wasdeveloped by FTC&H. These activities are summarized in Final Additional Studies/Predesign Report,1996

1.3 RECORD OF DECISION

The ROD for the first operable unit at the MWDS was signed on September 30, 1991. The firstoperable unit included the waste mass and the groundwater contamination in the perched and glacialaquifers at the MWDS. The groundwater contaminants requiring remediation, as determined by theRI, and the risk and toxicity assessments, are chlorinated volatile organic compounds (VOCs) andammonia.

SECTION 2________________REMEDIATION SCHEDULE

The planned remedial action schedule is presented on the following pages. The schedule has beendeveloped using Timeline Software. Timeline will be used by SHARP'S project manager to providereal-time monitoring and scheduling updates as the project progresses.

Initiation of site preparation and mobilization activities for construction of the landfill cap andgroundwater remediation system will occur in early April, 1997. Completion of the landfill cap isanticipated in October, 1997 with completion of the groundwater remediation system occurring inSeptember, 1997.

The Motor Wheel PRP group will provide monthly written progress reports to MDEQ and willschedule meetings as required to resolve outstanding issues. The monthly reports will include monthlyupdates and contractors logs as well as a summary of work completed.
