The SI was completed and approved November 24, 2008. It found that contamination exists at the dump, but no releases to the surface water nearby. The EPA Superfund Program has decided to "NFRAP"the site meaning no fiurther action is warranted at this time on the basis that there was no documented release to the Yellowstone River. A complete SI Report, SI Signature page, and SI Decision sheet is enclosed for the City's records. This report may also be of future use if the City plans on changing the usage of the old dump.

(UOS) under the U.S. Environmental Protection Agency (EPA) Region 8 Superfund Technical Assessment and Response Team 3 (START) Contract No. EP-W-05-050. This report has been prepared in accordance with the EPA "Guidance for Performing Site Inspections under CERCLA" (U.S. Environmental Protection Agency(EPA) 1992; EPA 1993). Field sampling activities were conducted on October 9, 2007 and followed the Site Inspection (SI) format, applicable UOS Technical Standard Operating Procedures(TSOPs),and the Generic Quality Assurance Project Plan(QAPP)(URS Operating Services,Inc. (UOS)2005a;UOS 2005b). This focused Sl report is intended to be used in conjunction with the Laurel Old City Dump Field Sampling Plan(FSP)(UOS 2007a). The Laurel Old City Dump is an inactive dump of approximately 2.5 acres on the banks of the Yellowstone River just downstream of the City of Laurel Municipal Water Treatment Center. The Billings Bench Water Association(BBWA)head gate at the west end of the site is the only open access to the site. The Yellowstone River,fenced private property, and the BBWA canal make the other borders of the site. 2.0 OBJECTIVES The objective of the Laurel Old City Dump SI is to gather information and data for the evaluation of this site with regard to the EPA's Hazard Ranking System (HRS) criteria. The site will be evaluated using analytical data provided in this report for an overall characterization of the site. The specific objectives of this SI are to: • Determine the contaminant characteristics of the source area and evaluate the source area by HRS criteria; • Evaluate contaminant migration through the Surface Water Pathway; • Evaluate the impact on groundwater and surface water targets;and • Determine the potential impacts to public health and the environment from source contaminants.

The geographic coordinates of the property are 45'39' 29.16"north latitude and 108' 45' 3.96" west longitude. The site itself lies just adjacent to and north of the Yellowstone River (Figure 2). To the north of the Laurel Old City Dump is a wastewater treatment plant that discharges into the Yellowstone River just downstream of the dump. Approximately 3/ of a mile to the west of the Laurel Old City Dump is the Cenex Refinery. To the south of the site on the opposite side of the river there are several private residences. The residences are approximately 1,000 feet to the south-southeast of the site. The nearest residence to the east is approximately one mile away. Directly east of the site is undeveloped land covered with native vegetation(UOS 2007b). 3.2 SITE HISTORY AND PREVIOUS WORK The land that eventually became the Laurel Old City Dump site was first conveyed to the town of Laurel on May 28, 1910,by Octavius K. Unger, Clara H. Unger, and W. L. G. Unger(TechLaw Inc. 2007). The site was developed into a municipal dump for the town where it operated until approximately 1954 or 1955 (Laurel Public Works Department (LPW) 2007a). There are no documents detailing if dumping was restricted or when dump operations began. In the time since the original purchase by the town of Laurel, ownership has not been transferred, but easements through the site have been granted for the construction and maintenance of various gas and oil pipelines(TechLaw,Inc.2007). The site historically operated as a dump used by the town of Laurel and the Farmer's Union Central Exchange (which later became the still operational Cenex refinery). The refinery claims that they did not send anything other than "household"wastes to the dump. All industrial waste was disposed of off of the refinery property(Cenex Corporation 2007). There is a lack of information about the waste composition in the dump. To date there has not been any investigation undertaken to identify possible contaminants. The sole documented TDD W 0705-02 T:\START3\Laurel—Old—City_pump\SI\SI Report Final\Laurel Old City Dump.doc URS Operating Services,Inc Laurel Old City Dump—Focused Sl Report START 3,EPA Region 8 Revision: 0 Contract No.EP-W-05-050 Date: 09/2008 Page 3 of27 complaint reported by the Montana Department of Environmental Quality (Montana DEQ) was recorded on September 9, 1999. The report indicated that broken glass, and dump refuse were washing from the bank of Yellowstone River 15 to 50 yards downstream of the BBWA Canal head gate. The Montana DEQ enforcement division followed up on the complaint and referred the site to the Montana DEQ Rtmediation Division in September 1999. The Montana DEQ did not perform any work at the site and later referred the site to Region 8 EPA(Montana Department of Environmental Quality(Montana DEQ) 1999). A Preliminary Assessment (PA) was performed by UOS in March 2007. -fbe PA prompted a focused SI. 33 SITE CHARACTERISTICS 33.1 Physical Geoswanhv The site is located in the Yellowstone River Valley on the north bank of the Yellowstone River,which flows toward the northeast and north. The BBWA canal forms the northern border of the site. The surface topography in the vicinity of the site generally slopes south-southeast toward the river. The site is located 3,297 feet above mean sea level and is situated to the southeast of the city of Laurel. Surface water runoff trends toward the Yellowstone River to the south. The site is approximately 2.5 acres in size(Figure 1). 33.2 Geology and Hydrogeoloav The geology of the site area consists of approximately 20 to 40 feet of recent Quaternary Yellowstone River alluvial material made up of gravel,coarse gravel, sand, silt, and clay. Because the site is on a cut bank of the Yellowstone River, it is likely that a significant portion of this material is very coarse and well rounded gravel to cobble sized material, especially on the river banks. Most of the recent alluvial material has been derived from the underlying Upper Cretaceous shale units. The thickness of these underlying shale units is unknown but is likely significant (possibly as much as 1,000 feet). No other significant structural geologic features are located within four miles of the site (Montana Bureau of Mines and Geology 2000). TDD No.0705-02 T:\START3\Lauml_Old_City_Dump\SI\SI Report Finahl-aural Old City Dump.doc URS Operating Services,Inc laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision: 0 Contract No.EP-W-05-050 Date: 08l2009 Page 4 of 27 A search of the Montana Ground Water Information Center (MT GWIC) identified 30 wells in Section 15,with the majority of them being monitoring wells associated with the Cenex Refinery located approximately '/a mile west of the site (Montana Groundwater Information Center (MT GWIC) 2007). Only three domestic wells and one irrigation well were identified within section 15. All wells were completed in the alluvial aquifer or slightly into the underlying shales. Total depths of all wells in the section ranged from 13.3 feet below ground surface (bgs) to 30 feet bgs with an average depth of 19.3 feet bgs. Because of the proximity to the Yellowstone River, static water levels in the section were very shallow and ranged from 2.2 feet to 13 feet bgs with an average of about 7.92 feet bgs. Groundwater in the area likely flows toward and/or parallel to the Yellowstone River(MT GWIC 2007). 33.3 Hydrology Surface water.drainage from the site area is believed to flow to the southeast from the site toward the Yellowstone River, which forms the southern border of the site. The BBWA canal forms the northern border of the site, surface water flows away from the river into the BBWA canal and then northeast toward Billings (Figure 3). Because the site is unpaved, a portion of the surface water drainage from the site likely infiltrates to shallow groundwater as well. 33.4 Meteorology The Laurel Old City Dump site is located in a semiarid climate zone. The mean annual precipitation as totaled from the University of Delaware (UD) database is 14.61 inches. The net annual precipitation as calculated from precipitation and evapotranspiration data obtained from the UD database is 2.52 inches (University of Delaware, Center for Climate Research, Department of Geography 1986). The 2-year, 24-hour rainfall event for this area is 1.5 inches(Dunne,Thomas and Luna B.Leopold 1978). TDD No.0705-02 T:\START3\LAureLOid—City_pump\SI\SI Report Final\Laurel Old City Dump.doc URS Operating Services,Inc Laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision- 0 Contract No.EP-W-05-050 Date: 08/2008 Page 5 o1727 4.0 PATHWAY CHARACTERIZATION 4.1 SOURCE CHARACTERIZATION The Laurel Old City Dump was an uncontained and apparently unlined landfill that operated while under the ownership of the city of Laurel until approximately 1954 or 1955. The city of Laurel has no record of when the dump began operations (LPW 2007a). Based on the limited information about the site and time period when it was active,it is likely that that it was operated as an open dump. The site is approximately 2.5 acres in size (Figure 1)and the depth varies from approximately eight to ten feet(UOS 2007b). 4.2 GROUNDWATER PATHWAY According to Mr. Larry McCann of the Laurel Public Works Department, Montana state law requires any resident located within 300 feet of a public water supply line to make a connection to that public water supply (LPW 2007b). According to Mr. McCann, there are approximately 2,600 connections to the city of Laurel water supply from the surface water intake (located approximately 0.40 mile west of the site on the Yellowstone River) (LPW 2007b). The average number of persons per household in Yellowstone County, Montana, is 2.45. Assuming that each connection serves one household,the total number of residents using the public water supply can be calculated to be approximately 6,400 people. For the purposes of this report, if there are approximately 9,129 residents within the four-mile study area, then it is conservatively assumed that the approximately 2,730 remaining residents within the study area are obtaining their drinking water from private wells located in the shallow aquifer. It is also assumed that of the population being served by private domestic wells, approximately 500 of these residents reside within the two-to three-mile radius ring from the site and approximately 2,230 of these residents reside within the three- to four-mile radius ring from the site (U.S. Department of Commerce, Bureau of the Census 2000). The three closest domestic groundwater wells are located approximately 0.3 to 0.4 mile southeast of the site. Static water levels in these wells range from seven to twelve feet bgs. Groundwater in the area likely flows toward and/or parallel to the Yellowstone River(MT GWIC 2007). TDD No.0705-02 T:\START3\Laurel_Old_City_Dump\SI\SI Report Final\Laurel Old City Dump.doc URS Operating Services,Inc Laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision: 0 Contract No.EP-W-05-050 Date: 08/2008 Page 6 of27 The nearest U.S. Geological Survey (USGS) monitoring site, number 06214500, is located downstream of Laurel in Billings, Montana, on the periphery of the Laurel Old City Dump study area. Volatile organic compounds (VOCs) were detected in the quatemary aquifers, and to a much lower extent the lower tertiary aquifers during North American Water Quality Assessment (NAWQA)investigations between 1999 and 2006. Although detected,levels of VOCs primarily associated with gasoline and the petroleum refining process were well below federal drinking water standards(U.S.Geological Survey(USGS)2001). 43 SURFACE WATER PATHWAY The Laurel Old City dump is located directly adjacent to the Yellowstone River and the BBWA canal. The site is the.immediate highpoint in the area; as such, all overland flow and runoff will drain into either the BBWA canal or the Yellowstone River. The water in the BBWA canal is used for crop irrigation for farmlands between and west of the cities of Laurel and Billings. Annual mean flow of the Yellowstone River in this particular area is 198 cubic meters per second (m3/sec) (6,988 cubic feet per second (ft3/sec)) (Boughton et al 1999). The site lies within the 100-year floodplain of the Yellowstone River (Montana Natural Resource Information System (MNRIS) 2007). The municipal water intake for the city of Laurel is upstream of the site and feeds directly off of surface water from the Yellowstone River. The city of Billings municipal water intake is more than 15 miles downstream of the site. Laurel does not require the use of groundwater wells,rather relying completely on surface water for its municipal supply. The threatened and endangered species of concern within the township and range are listed in Table 1. The U.S. Fish and Wildlife Service (USFWS) and USGS have not mapped a wetlands inventory for Yellowstone County, Montana, along the 15-mile Target Distance Limit (TDL) (Figure 1); however, small wetlands may exist and would need to be confirmed should further action be necessary for this site(U.S.Fish and Wildlife Service(USFWS)2007;USGS 1982). The Yellowstone River and the Clark Fork of the Yellowstone River come together just downstream of the city of Laurel. This section of the river contains many designated fisheries, such as Homestead Isle and Buffalo Mirage,which are on the Yellowstone River just upstream of the city of Laurel and located in relatively close downstream proximity to the site is the Duck TDD No.0705-02 T:\START3MLaureLOid—City_Dump\SASI Report FinaN.Aurel Old City Dump.doc URS Opmting Services,Inc Laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision: 0 Contact No.EP-W-05-050 Date: 08/2008 Page 7 of27 Creek Bridge fishery. There is also a boat launching ramp on the opposite side of the Yellowstone from the site approximately 200 yards upstream (Montana Fish, Wildlife, and Parks 2007). Species listed by the Montana Department of Fish,Wildlife and Parks for the Clark Fork include brown trout, burbot, mountain whitefish and rainbow trout. The waters of the Upper Yellowstone immediately upstream of the Clark Fork, including the section nearest the site, are habitat to brown trout, burbot, channel catfish, mountain whitefish, rainbow trout, sauger, smallmouth bass,and the Yellowstone cutthroat trout(Montana Fish,Wildlife,and Parks 2007). Water quality of the Yellowstone River in the area is affected more by geologic and climatic factors than human influence. Such is evident by the low occurrence of manufactured compounds in streams, sediment, and fish compared to studies done in other similar surface water body investigations performed by the USGS NAWQA Program(USGS 2007). 4.4 SOIL EXPOSURE AND AIR PATHWAY Uncontained and Unregulated dumps are typical during the operational window of the Laurel Old City Dump. During the on-site visit, solid waste was seen protruding from areas of both vegetated ground and bare ground on the surface of the site. There are currently no residences or buildings on the property. The site has unregulated access at the southwest entrance, which is a narrow road across the top of the BBWA head gate devoid of any gate. The site is bordered on the northeast by private lands, but neither gate nor fence surrounds this site. The residential population within a four-mile radius is listed in the table below (U.S. Department of Commerce, Bureau of the Census 2000). Endangered and threatened species are listed in Table 1. Population within Four Miles of the Site Radius(miles) Population 0-0.25 59 0.25 - 0.50 12 0.50- 1.0 30 1.0-2.0 5,319 2.0-3.0 3,176 3.0-4.0 533 Total Population 9,129 TDD No.0705-02 T:\START3\Laurel—Old_City—Dump\SI\SI Report Final\Lauml Old City Dump.doc URS Operating Services,Inc Laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision: 0 Contract No..EP-W-05-050 Date: 08/2008 Page 8 of 27 The Laurel Old City Dump has not been operational for approximately 50 years, and as such some wastes are visible and exposed to air. However the absence of on-site workers, prevailing wind conditions, and the small population located in the immediate area greatly ameliorate the Potential impact of a release to air. 5.0 SITE INSPECTION FIELD ACTIVITIES The START field sampling team consisted of Chris Myers and Bryan Williams.Fieldwork was conducted in Level D PPE on October 9, 2007. All sampling activities and sample collection protocol followed those specified in the approved FSP except where noted in this report. 5.1 SURFACE SOIL SAMPLING Surface Soil samples were collected from the riverbank above where the Laurel Old City Dump comes in contact with the Yellowstone River. Surface Soil samples were collected according to UOS TSOP 4.16, "Surface and Shallow Depth Soil Sampling." Two samples were collected as opportunity soil samples from areas in the bank that were in direct contact with visible waste, protruding from the side of the landfill. Sample LDSO01 was collected from the base of the bank near the river(Appendix B) (Photo 3). Sample LDS002 was collected from what appeared to be a seep coming from the bank of the dump(Photo 4). Other planned surface soil and source samples were not collected during the sampling event based on the professional judgment of the sampling team. It was the consensus and decision of the field team that the surface soil samples collected are representative of the source materials on site. Source samples were omitted from the sampling plan because there was no delineation between source and soil at the banks of the Yellowstone River. Sediment at the bank of river was most likely derived from the dump; evidence of sloughing could be seen in the water coming from refuse originating in the walls of the bank(Photo 2). Analytical results are presented in Section 5.0 of this report. Laboratory Form. Is are presented in Appendix B. TDD No.0705-02 T:\START3\Lawel_Old—City_Dump\SI\SI Report Final\Laurel Old City Dump.doc URS Operating Services,Inc Laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision: 0 Contract No.EP-W-05-050 Date: 08/2008 Page 9 of 27 5.2 SURFACE WATER AND SEDIMENT SAMPLING Five surface water samples were collected and collocated with sediment samples. One duplicate was collected at the time of sampling for lab Quality Assurance/Quality Control (QA/QC). Samples were collected from downstream to upstream to minimize any possible cross contamination. Sampling was conducted according to UOS TSOP 4.18 "Surface Water Sampling," and parameters were collected per TSOP 4.14 "Water Sample Field Measurements," guidelines. Sample LDSW06 was collected the farthest downstream, from an area that could be, but has not been classified as a sensitive environment. Samples LDSW05, LDSWO4, and LDSW03 were collected just off of the bank of the dump. Sample LDSW02 was not collected because it was felt that a representative survey of the landfill had been achieved. Sample LDSWOI was collected upgradient of the site in order to establish background levels. Sample LDSW07 was collected at the same location as sample LDSWOI for laboratory duplicate analysis. Five sediment samples were collected from the study area. One duplicate was collected at the time of sampling for lab QA/QC analyses. Sediment samples were collected according to UOS TSOP 4.17 "Sediment Sampling." Samples were collected from downstream to upstream to minimize any possible crass contamination. Surface water samples at the same locations were collected before sediment samples. Samples were collected in order from locations LDSD06 to LDSDOL Sediment sample LDSD02 was not collected because corresponding surface water sample LDSW02 was deemed unnecessary,as a good representation of the conditions had already been achieved. Sample LDSD07 was collocated with sample LDSDOI for laboratory duplicate analysis. Laboratory form Is are presented in Appendix B. 6.0 LABORATORY DATA ANALYSIS 6.1 SURFACE SOIL SAMPLES Two surface soil(source)samples(LDSO01 AND LDSO02)were collected from the bank of the Laurel Old City Dump,. The samples were analyzed for Target Analyte List (TAL) total metals plus mercury, VOCs,.semivolatile organic compounds (SVOCs), pesticides and polychlorinated TDD No.0705-02 T:\START3\Laurel_Old_City_Dump\SI\SI Report Final\Laurel Old City Dump.doc URS Operating Services,Inc Laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision: 0 Contract No.EP-W-05-050 Date: 08/2008 Page 10 of27 biphenyls (PCBs) by an EPA Contract Laboratory Program (CLP) Routine Analytical Services (RAS)laboratory. Of the two samples analyzed for TAL metals,only chromium in sample LDS002 was detected at levels higher than the Superfund Chemical Data Matrix (SCDM benchmark. All other analytes were below SCDM benchmarks. Metals results are listed in Table 2. SVOC results from the surface soil (source) samples are presented in Table 3. Analytical data shows that only benzo(a)pyrene was detected above the SCDM benchmark for sample LDSO02. Surface soil (source) sample results for pesticides/PCBs are presented in Table 4. Sample LDSO01 contained levels of 4,4'-DDE, 4,4'-DDT, and Dieldrin above SCDM benchmarks. Sample LDS002 contained 4,4'-DDE, 4.4'-DDT, heptachlor epoxide, and Dieldrin at levels above benchmarks. No VOCs were present in either of the source samples. 6.2 SEDIMENT SAMPLES Sediment samples were analyzed for TAL total metals plus mercury, VOCs, SVOCs, pesticides, and PCBs by an EPA CLP RAS laboratory. Metals results for the sediment samples include, but are not limited to the following: lead and cadmium were detected in the sediment samples above three times the measured background levels. Results are presented in Table 5. Mercury was also measured above the non-detect background level in samples LDSD03 and LDSD04; however, mercury results for both samples were far below benchmarks. Arsenic was detected in every sample; however none exceeded three times the measured background level. SVOC results for the sediment samples were all below three times the background levels for the entire sample delivery group.Analytical results for this analysis are presented in Table 6. VOCs were not detected in any of the samples above three times the background level with an exception of carbon disulfide in sample LDSD05. The compound was detected above the TDD No.0705-02 T:\START3\Lawel_Old_Cit3_Dump\SI\SI Report FinalUaurel Old City Dump.doc URS Operating Services,Inc Laurel Old City Dump—Focused SI Report START 3,EPA Region 8 Revision: 0 Contract No.EP-W-05-050 bate: 082008 Page 11 of27 instrument detection limit but below the CRQL. Results for this delivery group are presented in Table 7. Pesticides/PCBs were detected at levels greater than three times background, or above the corresponding non-detect background levels,in sediment samples taken from the site. 4,4'-DDD, 4,4-DDT, delta-BHC, Aldrin, Dieldrin endosulfan II, Endrin, gamma chlordane, heptachlor and heptachlor epoxide were detected in several of the samples,however none are above the Contract Required Quantitation Limit(CRQL). Results are presented in Table 8. 63 SURFACE WATER SAMPLES Surface water samples were analyzed for TAL total metals plus mercury, VOCs, SVOCs, pesticides,and PCBs by an EPA CLP RAS laboratory. Metals contamination was not above three times the background level for any analyte on the TAL total metals list. Results are presented in Table 9. Arsenic contamination was above benchmarks; however, none of the results were greater than three times the measured background. There were no results higher than the instrument detection limit for SVOCs or VOCs in any of the surface water samples collected. There were detections for heptachlor in samples LDSW01 and LDSW03 above the instrument detection limit but below the CRQL. The results were "P" flagged by the lab in the final data however. The "P" flag is a function of the two columns that are used for the analysis of this pesticide.If there is a positive detection on the first column at the retention time for the analyte of concern, the sample is run on a second column for confirmation. A "P" flag is indicative of a detected compound whose retention time between the two columns varies less than 25% but is still not a direct match. The data reviewer felt that the P-flags could be removed and replaced with U (non-detect) due to the discrepancy between columns. Levels of the tentatively detected compounds fell far below SCDM benchmarks. All partial data review was performed by a UOS staff chemist and will be saved pending the necessity of a full data review.

It is an unregulated dump that was most likely operated from 1910 to 1955. A complaint was filed with the Montana DEQ in September 1999 pertaining to an observation of sloughing of dump materials into the Yellowstone River. The Montana DEQ eventually passed the site to the Region 8 EPA Site Assessment Program. A START field team collected surface water, sediment, and surface soil (source) samples on October 9 2007, from the Laurel Old City Dump. Analytical results from this sampling event indicated that the surface water at the site does not contain any contaminants of TAL metals, SVOCs, VOCs or pesticides/PCBs. Arsenic levels were elevated at the site, but none of the results were greater than three times the background sample. Surface soil (source) samples contained elevated levels of pesticides/PCBs, chromium, and benzo(a)pyrene; however, analytical data support that there was no documented release to the Surface Water Pathway. Surface water samples at the Laurel Old City Dump contained no elevated levels of pesticides/PCBs, metals from the TAL list, SVOCs,or VOCs above background samples taken from upstream of the site. Although data indicate that sediments in the area of the site contained pesticides/PCBs, because none of them are detected above the CRQL for any of the samples, they will have no impact on the HRS score of the site.
