PHASE I ENVIRONMENTAL SITE ASSESSMENT SOUTH WATERFRONT GREENWAY SITE – CENTRAL DISTRICT SW GIBBS STREET TO SW LANE STREET PORTLAND, OREGON

1.0 SUMMARY OF FINDINGS

This report presents the results of our Phase I Environmental Site Assessment (ESA) of a 100- to 150-foot wide Greenway along the west bank of the Willamette River between SW Gibbs and SW Lane Streets in the Central District of the North Macadam Urban Renewal Area (Figures 1 and 2). The Greenway site consists of two tax lots, which are owned by River Campus Investors, LLC (RCI) and North Macadam Investors, LLC (NMI) and were once part of larger parcels. A summary of our findings of the Phase I ESA follows. Based on a review of available information, we identified potential environmental concerns as a recognized environmental condition (REC), a historical REC, or a de minimis condition. A recommendation for additional assessment, if warranted, is also presented for each concern. Please refer to the remainder of text for additional discussions of these findings.

1.1 Recognized Environmental Concern

RECs are defined in ASTM E 1527-05 as the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property.

1.1.1 Potential for Localized Areas of Contaminated Soil

From our research, we identified the potential for localized areas of contaminated soil as a REC. The subject property has been filled, mostly in the 1920s prior to development; however, a shipway was located within the central portion of the Greenway, and was filled in the mid 1960s. Several localized areas of soil contamination have been encountered which were subsequently remediated (see Section 1.2.2). As part of this Phase I ESA, a geophysical survey was performed over the subject property. Seventeen magnetic anomalies were identified consisting of likely buried demolition debris and/or buried metal. Based on previous areas of soil contamination, historical filling, and geophysical anomalies, the potential for additional localized areas of contaminated soils exists.

Recommendations. We recommend a focused Phase II investigation of geophysical anomalies indicating buried debris as well as former areas of soil contamination that

Hart Crowser Page 1 15663-00 December 20, 2007

may be excavated in the near future as part of the greenway development. If the Phase II investigation reveals contaminated soils, a soil management plan (SMP) should be prepared and implemented to assist the earthwork contractor and/or environmental consultant in identification and management of contaminated soil.

1.1.2 Contamination from Historical Activities

Industrial activities have occurred on and adjacent to the subject property from the 1930s through the 1990s. The northern portion of the property was a shipbuilding facility during World War II. A shipway was constructed within the central portion of the property for this facility; it was later filled in the mid 1960s. From the late 1940s to the early 2000s, the northern portion of the property was occupied or used by commercial/ industrial facilities, including steel and metal fabricating, road construction, general construction and electrical products manufacturing. The southern portion of the property was primarily used from the 1930s through 1980s for gravel crushing and concrete production plants. Previous environmental assessments were conducted in the 1990s and 2000s on the subject property, which encountered localized areas of soil contamination (Section 1.2.2) and also low levels of contamination. For this Phase I ESA, we attempted to obtain the actual chemical data, but mainly acquired only project summaries. In 2002, the subject property was sloped back; excavated soils were screened and placed again on the property as a 1 to 2 feet layer of topsoil.

Recommendations. Several potential environmental concerns may be associated with historical activities: contamination from the activities themselves (e.g., the shipbuilding facility; fill material placed on the property (i.e., shipway); and excavation of these soils, with subsequent screening and spreading back over the property. We recommend a focused Phase II investigation of soils potentially affected by historical activities including soils that may be excavated or exposed in the near future as part of the greenway development. If the Phase II investigation reveals contaminated soils, a SMP should be prepared as described above. We also recommend that documents that were unavailable for our review (Section 12.2) be obtained and reviewed for information and chemical data pertinent to the subject property.

1.2 Historical RECs

Historical RECs are defined in ASTM E 1527-05 as environmental conditions, which in the past would have been considered a REC, but which may not be currently considered a REC. If a past release of any hazardous substances or petroleum products has occurred in connection with the property and has been remediated, with such remediation accepted by the responsible regulatory agency (i.e., a “No Further Action” [NFA] letter), this condition should be considered a historical REC.

Hart Crowser Page 2 15663-00 December 20, 2007

1.2.1 Former Underground Storage Tank Excavation

In 1995, two underground storage tanks (USTs) were removed from the NMI property. Approximately 840 tons of diesel-contaminated soil was excavated from the UST nest. This excavation extended into the subject property. Confirmation samples from the final excavation limits indicated diesel concentrations less than DEQ Level II Soil Matrix cleanup standards (500 mg/kg). (The maximum diesel detection was 180 mg/kg in a sample at 13.5 feet bgs at the east end of the excavation.) The DEQ issued a “No Further Action” (NFA letter) on September 4, 1996.

Recommendation. None. If deeper excavations (greater than 10 feet deep) are conducted in this area during greenway development, an environmental consultant should evaluate any potential unforeseen diesel-contaminated soil; any contaminated soil encountered should be properly managed in accordance with a SMP.

1.2.2 Remediation of Localized Areas of Soil Contamination

Several localized areas of soil contamination have been previously encountered within the Greenway during prior environmental investigations and during grading of the greenway property as part of the development of South Waterfront. All these areas were remediated by soil excavation and off-site disposal. These areas are as follows (from north to south as shown on Figure 2).

TP-33 Excavation. Approximately 18 tons of lead-contaminated soil were excavated from 6 to 9 feet below the ground surface (bgs) from the northern portion of the Greenway. The residual lead concentration in the excavation bottom sample was 70.6 mg/kg.

Subsurface Vault. A vault with liquid and sludge was discovered in the northern portion of the Greenway in the late 1990s. After removal of its contents and the vault itself, approximately 88 cubic yards (cy) of petroleum contaminated soil were removed. Petroleum constituents were not detected in confirmation soils samples or in groundwater from a well installed downgradient of the vault.

Southeast Corner Excavation. Approximately 950 tons of diesel-contaminated soil was removed from between 4 and 7 feet bgs within the central portion of the Greenway. Diesel was not detected in confirmation samples.

TP-29 Excavation. Polynuclear aromatic hydrocarbons (PAHs) were detected in soil next to a timber pile in test pit TP-29 in the southern portion of the Greenway. Approximately 100 tons of soil was removed between 13 and 20 feet bgs. Two PAHs were detected in a confirmation sample from excavation bottom; however, they were below risk-based concentrations (RBCs) for residential soil.

Hart Crowser Page 3 15663-00 December 20, 2007

Concrete Support Excavation. In 1995, approximately 240 tons of petroleum- contaminated soil was excavated from beneath a concrete support of the former structure in the southern portion of the Greenway. Total petroleum hydrocarbons (TPH) were not detected in confirmation soil samples.

The Oregon Department of Environmental Quality (DEQ) prepared Staff Reports for both the RCI and NMI properties (DEQ, 2004, 2005b), in which the Greenway is a part. In these Staff Reports, the above areas were addressed. The DEQ concluded that these areas did not warrant further action.

Recommendation. None; however, see Section 1.1 regarding the potential for additional areas of unforeseen soil contamination.

1.2.3 Suspected Former Paint Waste Pond

A suspected former paint waste pond was identified along the property boundary of the RCI property and Zidell Marine in a previous Phase I ESA, likely from a 1943 map for the Zidell facility and historical aerial photographs. This suspect pond was located west of the northern boundary of the Greenway. Environmental investigation of this area encountered a thin layer of non-native white silt material from 3 to 4 feet bgs. Analysis of this material, adjacent soil, and groundwater in the area did not detect petroleum or chemical constituents above regulatory cleanup levels or accepted background levels. Based on this data, the DEQ concluded in their Staff Report (DEQ, 2004) that no further action in this area was required.

Recommendation. None; however, if any non-native suspect material is encountered during greenway development, an environmental consultant should evaluate the material to assess whether it requires any special handling or disposal.

1.2.4 Former Shipway

A shipway was present in the southeastern portion of the RCI property from 1942 through the mid 1960s. Figure 2 shows the location of this shipway. Environmental activities were conducted within fill placed in this shipway and to the west. Limited amounts of chemical contamination were detected in the area to the west of the Greenway. These areas were remediated through limited soil removals in 2002 and during excavation for two levels of subgrade parking in 2004. Sample results from this excavation, including three samples obtained from the shipway, did not detect petroleum hydrocarbons or metals above background concentrations. The block represented by this excavation (Block 30) has received an NFA letter from the DEQ.

Recommendation. None.

Hart Crowser Page 4 15663-00 December 20, 2007

1.2.5 Shallow Groundwater

Shallow groundwater on the RCI and NMI properties (which includes the Greenway) has been evaluated from groundwater monitoring wells and push probes. The shallow groundwater table is present beneath these properties at 12 to 25 feet bgs, and generally flows toward the east, ultimately discharging into the Willamette River. Minor concentrations of chemical contaminants have been detected. In their Staff Reports (DEQ, 2004, 2005b), the DEQ indicated that shallow groundwater was not currently used or reasonably likely to be used as a source of drinking water at or near these properties. Based on an evaluation of chemical data on groundwater and comparison to DEQ freshwater aquatic screening level values (SLVs), the DEQ concluded that groundwater has not been adversely affected and no further action is required.

Recommendation. None (see also Section 1.3.1 regarding monitoring wells).

1.3 De Minimis Conditions

De minimis conditions are defined in ASTM E 1527-05 as generally not posing a risk of harm to public health or the environment and generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. The following de minimis conditions were identified.

1.3.1 Monitoring Wells

Three monitoring wells were observed on the subject property. These wells are shown on Figure 2, along with other former monitoring wells that were once present (these wells could not be found during our site visits). One well (MW-1) at the end of the walking path was observed to be in poor condition, with the entire monument and casing protruding above grade. As shallow groundwater is not a concern to the DEQ (Section 1.2.5), these wells are no longer needed.

Recommendation. We recommend that the wells should be decommissioned. As the properties are in the Independent Cleanup Pathway in the DEQ’s Voluntary Cleanup Program, a request to decommission the wells should be submitted to the DEQ and, upon approval, the wells should be decommissioned. If any other wells are encountered during greenway development, they should be properly decommissioned.

1.3.2 Stockpiles

Several small stockpiles were observed on the subject property during our September 29, 2007, site reconnaissance. The stockpiles were observed along the west side of the northern portion of the Greenway. Fill material/dirt and building material fragments, consisting of cinderblocks, PVC piping, wires, wood, cables, and

Hart Crowser Page 5 15663-00 December 20, 2007

metal were observed. On a subsequent site visit on November 7, 2007, two piles remained. Only one had concrete debris.

Recommendation. None. It is unknown if the stockpiles will be used for future site grading or are slated for off-site transport and disposal. If the stockpiled soil is used for site grading or fill, the origin of the pile should be determined or it should be screened for chemical contamination.

1.3.3 Discharges to the Willamette River

Currently, several stormwater outfalls enter into a bioswale constructed in the southern portion of the Greenway. Surface water runoff from streets in the South Waterfront Central District and likely adjoining developments is directed through the bioswale. Water is then discharged to the Willamette River. Historically, businesses occupied the Greenway and may have discharged storm, waste, and/or process water to the Willamette River (the former gravel plant on the NMI property had a National Pollutant Discharge Elimination System (NPDES) permit; abandoned outfalls were observed). Overwater and moorage activities were also conducted. In a 1955 aerial photograph, turbidity is noted in the river originating from the docks at the NMI property. Information on sediment quality adjacent to the subject property was not found during our review, including in DEQ Staff Reports.

Recommendations. None. Upon review of the property information, the DEQ Staff Reports (2004, 2005b) do not present concerns regarding sediment. If possible, indemnification for historical releases to the river should be sought as part of the purchase agreement. All stormwater discharge pipes should be confirmed to have valid DEQ discharge permits. Greenway development should also implement best management practices for erosion during construction (e.g., silt fences) and after construction (e.g., vegetation, riverbank stabilization).

2.0 INTRODUCTION

This report presents the results of our Phase I ESA of the subject property, a 100- to 150-foot wide greenway (hereafter, called the Greenway) along the west bank of the Willamette River between SW Gibbs and SW Lane Streets in the Central District of the North Macadam Urban Renewal Area (Figures 1 and 2). We understand that the Portland Development Commission (PDC) is planning on acquiring the Greenway for development as part of the larger South Waterfront Greenway that will extend 1.2 miles along the west bank of the Willamette River. As part of their due diligence, PDC requested a Phase I ESA be performed.

2.3 Special Terms and Conditions

Work for this project was performed, and this report prepared, in general accordance with ASTM guidance, 40 CFR 312 for AAI, and generally accepted professional practices for the nature and conditions of the work completed in the same or similar localities, at the time the work was performed. It is intended for the exclusive use of the PDC for specific application to the subject property. This report is not meant to represent a legal opinion. No other warranty, express or implied, is made.

3.0 SITE DESCRIPTION

3.1 Location and Vicinity General Characteristics

The subject property, the Greenway, is located on the west bank of the Willamette River between SW Gibbs and SW Lane Streets in Portland, Oregon (Figures 1 and 2). The subject property comprises two tax parcels 1S1E10AC-00309 (north parcel) and 1S1E10DB-00201 (south parcel). The north parcel is situated in the SW 1/4 of the NE 1/4 of Section 10, Township 1 South, Range 1 East and the south parcel is situated in the NW 1/4 of the SE 1/4 of Section 10, Township 1 South, Range 1 East, Willamette Meridian.

The subject property and surrounding area are located in the Central District of the North Macadam Waterfront Urban Renewal Area (this area is also called South Waterfront). The area is in a mixed multi-family, commercial, and light-industrial area and is zoned as Central Commercial (CX), with a design (d) overlay. The Greenway also has a river general (g) overlay, which allows for public use and enjoyment of the waterfront and enhances the river’s natural and scenic qualities. The Willamette River flows northward east of the subject property, and provides anadromous fish passage, salmonid fish spawning, resident fish and aquatic life, aesthetic quality, recreation, transportation, wetland areas, fishing and hunting, and wildlife habitat.

3.2 Current Use and Description of Property

The subject property is a 100- to 150-foot wide Greenway along the west bank of the Willamette River between SW Gibbs and SW Lane Streets (Figures 1 and 2). It is comprised of two tax parcels, which are described and owned as follows.

Tax parcel 1S1E10AC-00309, the northern portion, extends from SW Gibbs Street to SW Pennoyer Street. It is 2.56 acres in size and is owned by River Campus Investors, LLC (RCI). This tax parcel is the easternmost portion of a previous larger property, the RCI property (17 acres), which extended from the river to SW Bond Avenue.

Hart Crowser Page 8 15663-00 December 20, 2007

Tax parcel 1S1E10DB-00201, the southern portion, extends from SW Pennoyer Street to SW Lane Street. It is 1.79 acres in size and is owned by North Macadam Investors, LLC (NMI). This tax parcel is the easternmost portion of a previous larger property, the NMI property (10 acres), which extended from the river to SW Bond Avenue.

From September through November 2002, the Greenway was constructed by laying back the existing bank at a 4 horizontal to 1 vertical (4H:1V) slope from the ordinary high water line of the Willamette River (the east boundary of the subject property is the ordinary high water line; however, because there is no clear demarcation of this boundary, the riverbank is also described as part of the subject property). The Greenway was then hydroseeded. Currently, the Greenway consists of grass-covered strip improved with an asphalt-paved walking path, which transverses the subject property in a north-south direction. The southernmost portion of the subject property is unimproved and contains a bioswale with several stormwater outfalls. The riverbank along the eastern perimeter of the Greenway is covered/armored with concrete debris or aggregate; bushes and trees are also present at the northern end. Appendix A includes representative photographs of the subject property.

Utilities in the area include electricity, storm sewer, sanitary sewer, city water, communication, and natural gas. As described above, a stormwater bioswale is present at the southern end of the Greenway. The City of Portland has an easement for this area (Rowe, 2007). A likely abandoned outfall pipe at the riverbank is present in the central portion of the Greenway. Power lines cross over the north end of the Greenway as part of Pacific Corp easement (Rowe, 2007). No water wells were identified on the subject property (three monitoring wells, however, are present – see Section 6.1).

3.3 Adjoining Property Use and Description

Adjoining properties, as defined in ASTM E 1527-05, are any properties that border the subject property, or would border the property except for a public thoroughfare separating them. Adjoining properties consist of the following uses (see Figure 2).

To the west by five blocks (Blocks 23, 27, 30, 34, and 37; Figure 2; a map of the blocks is included in Appendix B). The two blocks on either side of Pennoyer Street have been developed with condominium towers: consisting of two towers of 21 and 23 stories; and Atwater Place consisting of a 22 story building. Blocks 23 and 27 are currently undeveloped, and Block 37 is being used as construction staging area for Atwater Place.

To the north by Zidell Marine Corporation, currently a barge building facility.

To the south by vacant land, currently used for construction staging.

To the east by the Willamette River.

4.0 USER PROVIDED INFORMATION

The following section summarizes information provided by Robert VanVickle of the PDC (User) with regard to this Phase I ESA.

4.1 Recorded Instruments on Property

Mr. Van Vickle was unaware of any environmental liens, engineering controls, or institutional controls in place or recorded for this property. Title records were not provided for the subject property.

4.2 Specialized Knowledge and Property Information

Mr. Van Vickle indicated that he did not have firsthand knowledge of potential activities on or adjacent to the subject property that may have resulted in chemical contamination to the subject property. He provided a 2004 Phase I ESA covering the South Waterfront District of North Macadam Urban Renewal Area (Parametrix, 2004). This Phase I ESA included the Greenway and was reviewed for compiling information about the Greenway in Section 5.4. Mr. Van Vickle indicated that the purchase price for the subject property was not finalized.

4.3 Other User Provided Documents

Mr. Van Vickle provided an infrastructure plan for the South Waterfront Greenway; two property boundary surveys of South Waterfront which covered the Greenway property; and a owner representative contact for the subject property (Mr. Trevor Rowe of Williams & Dame Development Corporation) for interviewing and for requests for additional documents.

5.0 RECORDS REVIEW

We conducted a review of reasonably ascertainable records to identify past or present activities on or near the subject property that may have caused or contributed to potential or known environmental conditions on or beneath the subject property. Records reviewed included environmental records at regulatory agencies, records about the physical setting of the vicinity, historical documentation, and information provided by PDC, DEQ, and GeoDesign (an environmental consultant that performed work on the subject property). Pertinent copies of supporting documentation and the regulatory agency file search are provided in Appendices B and C, respectively.

Hart Crowser Page 10 15663-00 December 20, 2007

5.1 Environmental Records

This section describes the regulatory agency database lists reviewed by Enviornmental Data Resources (EDR), for sites of concern and information discovered during our review of publicly available information. EDR is a firm that acquires data from government agencies on various media such as magnetic tape, disk, and hard copy. The purpose of the regulatory agency database list review was to screen for potential sources of contamination or activities of environmental concern for the subject property and nearby properties.

5.1.1 EDR Database Search

EDR searched agency-published databases for sites of potential concern in accordance with current ASTM standards. The RCI and NMI properties from the Willamette River to Bond Avenue were used as the target property. Regulatory agency database lists reviewed and the search distances from the target property included the following.

U.S. Environmental Protection Agency (EPA) Lists Search Radius National Priorities List (NPL) 1 mile Delisted NPL Sites 1 mile Proposed NPL Sites 1 mile Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and its Information System (CERCLIS) List 0.5 mile CERCLIS No Further Remedial Action Planned (NFRAP) List 0.5 mile Corrective Action Report (CORRACTS) List 1 mile Resource, Conservation and Recovery Information System (RCRIS) Treatment, Storage, and Disposal (TSD) Facilities 0.5 mile Generators, Transporters, and Handlers 0.25 mile Institutional and Engineering Controls Lists 0.5 mile Emergency Response Notification System (ERNS) List Property

Hart Crowser Page 11 15663-00 December 20, 2007

The report of the database search provided by EDR is presented in Appendix C and includes: a list of databases searched; a summary of properties by list up to 1 mile from the subject property; selected detailed information from federal and state lists; and an overview map illustrating the identifiable and mappable sites found. The above databases include contaminated sites, hazardous waste generators, spills, USTs, and LUSTs. Refer to the EDR report for additional local database lists reviewed and for more detailed descriptions of regulatory listings.

Because our regulatory agency database search was based on the most current agency records available to EDR, our results are only as accurate as the records provided. We also supplemented the EDR search by reviewing the files on the DEQ’s Facility Profiler website (DEQ, 2007) and at the DEQ’s Northwest Region.

5.1.2 Subject Property

According to the EDR database search, the subject property was listed for both the RCI and NMI properties. No environmental (CERCLA) liens or federal- or state-listed institutional/engineering controls were indicated by EDR’s search for these properties.

RCI Property (US Bank Site). The RCI property consists of the 17-acre US Bank site and was listed on the ECSI (#4036), Brownfields, and VCS lists. The property was occupied with commercial and industrial facilities from the 1930s to the early 2000s. A shipway was present in the southeastern portion of the property from 1942 through the 1960s. Numerous environmental activities have been performed on the property, including the Greenway. A summary of the history of and environmental activities on the property is discussed in Section 5.4.1. The DEQ prepared a Staff Report (DEQ, 2004) that indicated that most issues had been addressed and no further action was generally necessary. Three blocks of this property have received NFA letters from the DEQ (Kaufman, 2007): Blocks 25 and 29 between Bond and Moody Avenues to the west, and Block 30 where The Meriwether condominiums has been constructed. The US Bank site is still within the Independent Cleanup Pathway (ICP) of the DEQ VCS, and other blocks may also receive an NFA letter after review of applicable data (Kaufman, 2007).

NMI Property (Pacific-Richland Site). The NMI property consists of the 10-acre Pacific Richland Site (aka Rosebud Holdings, Lone Star) and was listed on the Small Quantity Generator (SQG), FINDS, ECSI (#3993), UST, LUST, Brownfields, and VCS lists. This property was occupied by gravel crushing and concrete production plants from the 1930s through the 1980s.

The facility was listed as an SQG of hazardous waste for waste materials removed during remediation activities completed in 1995; the FINDS listing indicates that the facility was registered as a hazardous waste generator. The facility has undergone

Hart Crowser Page 12 15663-00 December 20, 2007

environmental investigation and cleanup, including the Greenway. The UST listing indicates eight decommissioned USTs which were removed in 1986 (one UST), 1990 (five USTs), and 1995 (two USTs). Two LUST listings (26-90-0018) and (26-95-0138) relate to releases reported during the 1990 and 1995 decommissionings; both received NFA letters in 1997 and 1996, respectively. A summary of the history and environmental investigation of the property is discussed in Section 5.4.2.

The DEQ prepared a Staff Report (DEQ, 2005b) that indicated no further action was necessary. The two blocks making up the northern portion of this property (Blocks 34 and 35) have received NFA letters from the DEQ (Kaufman, 2007). The property is still within the ICP, and other blocks may also receive an NFA letter after review of applicable data (Kaufman, 2007).

5.1.3 Adjoining Properties

According to our review of the EDR report, two sites are listed that are adjoining properties. These sites are discussed below. Upon review, these sites do not appear to pose a material threat to the Greenway.

Zidell Marine (3121 SW Moody). This site is located on the north side of Greenway and the RCI property. This site was present on the RCRIS-SQG, FINDS, NPDES, NFRAP, UST, AST, UIC, HSIS, ECSI (#689), CRL, and DEQ spills lists. Zidell Marine and is predecessors have been a shipbuilding and/or repair facility since the 1940s. Many of the listings are due to operations at the facility and investigations for contamination. The facility has undergone numerous environmental investigations, and in 2005, DEQ issued a Record of Decision (ROD) for Remedial Action at the facility (DEQ, 2005a). Upon review of the ROD, two areas of concern were noted adjacent to the subject property: a suspected former paint waste pond, and transformers south of the paint. These areas were assessed and no significant concerns were identified. The ROD does not identify any areas requiring cleanup within approximately 100 feet of the northern RCI property boundary. Because groundwater flow is eastward into the Willamette River and investigations on the RCI property have not noted any adverse impacts from the facility, the Zidell facility does not pose a material threat to the Greenway.

Prometheus Property (SW Bond). This site is located on the south side of Greenway and the NMI property and was occupied by an asphalt manufacturing plant. This site was present on the LUST, ECSI (#4007), and CRL lists. Two LUST releases are indicated on the property: 26-89-0034 for a heating oil UST release for Lakeside Industries (a previous owner), and 26-90-0195 for the North Landing Apartments (a potential development). Six USTs were decommissioned from the property, and in 1991, approximately 1,000 cubic yards (cy) of diesel-contaminated soil was removed from the UST pit. The LUST listings received NFA determinations in 1989 and 1991, respectively. However, no investigation of soils or groundwater beyond the UST pit

Hart Crowser Page 13 15663-00 December 20, 2007

was performed. Additionally, historical aerial photographs show holding lagoons were present on the property; their contents are unknown. Based on this information, the DEQ added this property to the ECSI database and CRL. Because groundwater flow is to the east into the Willamette River and investigations on the NMI property have not noted any impacts from this property, it does not appear to pose a material threat to the Greenway.

5.1.4 Surrounding Properties

The EDR report also identified the following 148 non-adjoining site listings within the ASTM-specified distances from the subject property.

List Number Any RECs? CERCLIS-NFRAP 2 No RCRA-Large Quantity Generator 1 No RCRA-SQG 12 No US Brownfields 1 No ECSI 34 No CRL 9 No LUST 68 No UST 8 No AST 1 No Manifest 3 No Institutional Controls 1 No VCS 5 No Brownfields 2 No EDR Manufactured Gas Plants 1 No

We reviewed the information reported by EDR regarding these sites to assess whether they posed potential environmental threats to the subject property. Seven sites were located upgradient (west) of the Greenway:

Bond Avenue Right-of-Way (Bond Avenue south of Lane Street) – ECSI and Brownfields lists;

Gibson-Homans Company (3419 SW Moody Avenue) – ECSI, SQG, FINDS, UST, LUST, and NFRAP lists;

Public Storage/Neighborhood Park (3508 SW Moody Avenue) – ECSI, UST, LUST, and VCS lists;

All Deck Block 39 Property (3732 SW Moody Avenue) – ECSI and VCS lists;

Hart Crowser Page 14 15663-00 December 20, 2007

Grunbaum Property/W.A. Winter/Block 33/Konnell Construction (3516 and 3604 SW Macadam Avenue) – ECSI, CRL, UST, LUST, and VCS lists;

Unocal 6114 (3714 SW Macadam Avenue) – UST list; and

La Grand Industrial Supply (3838 SW Macadam Avenue) – SQG, FINDS, AST, UST, LUST, and HSIS lists.

Based on DEQ Staff Reports for the RCI and NMI properties (DEQ, 2004, 2005b) of which the Greenway was a part, groundwater quality beneath these properties is not impacted and no further action is necessary. As such, these sites that are further upgradient do not pose a concern to the subject property.

5.1.5 Orphan Properties

EDR could not resolve all addresses based on information available in regulatory databases. Sixty-four sites were reported by EDR as “orphan” sites. Based on addresses provided, these “orphan” sites are not near the subject property.

5.2 Physical Setting Sources

This section provides a description of the physical setting of the site, which is useful in understanding the potential for contaminant migration in the subsurface. This discussion is based on information provided by investigations performed on or near the subject property; water well logs from the Oregon Water Resources Department (OWRD, 2007); and the USGS 7.5-minute quadrangle of Lake Oswego, Oregon (1984). References are included in Section 12.

Topography. Figure 1 shows the topography of the subject property and vicinity. The ground surface of the subject property is at an elevation of approximately 30 feet above mean sea level (msl), except for the riverbank which steeply drops to the Willamette River. In late 2002, the Greenway was grading by laying back the existing bank at a 4 horizontal to 1 vertical (4H:1V) slope from the ordinary high water line of the Willamette River (GeoDesign, 2002d). The closest water body is the Willamette River, which flows northward adjacent to the east side of the subject property. Portions of the facility are located within the 100-year flood zone; the property was flooded during the 1996 flood.

Geology. The top 1 to 2 feet of soil within the Greenway consists of soil screened from laying back the existing bank. Beneath this “top soil” is up to roughly 20 feet of fill material generally consisting of silty sand, sand, and gravel (GeoDesign, 2002d). Sandy material dredged from the Willamette River was placed on the native soils in the 1920s to raise the elevation of the Greenway and adjoining areas (Parametrix, 2004). The fill is thinnest near Bond Avenue and thickens to the east toward the

Hart Crowser Page 15 15663-00 December 20, 2007

Willamette River. Anthropogenic debris is sometimes present in fill material nearer the river, including metal, glass, concrete debris, brick, timbers, and rock ballast (DEQ, 2004). A large, subsurface concrete slab related to shipbuilding operations was encountered within the southeast portion of the RCI property (DEQ, 2004)

Native alluvial deposits consist of primarily of silty sand and sandy silt (OWRD logs, Hart Crower, 1995a). Two fairly continuous very dense gravel deposits were observed across the area. The first unit was encountered at depths between 36 and 55 feet bgs and is relatively thin (7 to 10 feet). A second, apparently thicker gravel unit, occurs at depths between 52 and 83 feet bgs and extended to the total depth of the explorations. According to geotechnical studies, the second gravel unit is relatively continuous and underlain by the Troutdale Formation or basalt bedrock (DEQ, 2005b).

Hydrogeology. Shallow groundwater generally occurs at depths ranging from 12 to 25 feet (9 to 14 feet msl) across the area. Groundwater flow is towards the east with a small northerly component. The hydraulic gradient is approximately 0.02 foot/foot. Groundwater discharges to the Willamette River (DEQ, 2004).

5.3 Historical Information

In 2004, Parametrix prepared a Phase I ESA for South Waterfront, which included the subject property (Parametrix, 2004). Historical information in this report was, however, summarized from a previous report (Century West, 2000), which was not available for our review. We researched the history of land use activities on and immediately surrounding the subject property using Internet sources, in-house library files, and other written documentation (including Phase I ESAs by others). The following sources were used:

Historical aerial photographs (Army Corps of Engineers – 1936, 1942, 1948, 1955, 1972, 1980, 1990, and 1998; GeoDesign, 2002a – 1936, 1939, 1940, 1942, 1944, 1948, 1956, 1957, 1961, 1963, 1968, 1984, 1988, 1992, and 1996; Simpson, 2004 – 1936, 1948, 1955, 1974, 1980, and 1996; City of Portland GIS, 2001 through 2006;);

Written documentation acquired by Hart Crowser from PDC, GeoDesign, and the DEQ.

Hart Crowser Page 16 15663-00 December 20, 2007

In summary, the Greenway and adjoining properties to the west were filled in the 1920s with material dredged from the Willamette River. Industrial development began in the 1930s a moorage on the RCI (northern) property and a gravel plant on the NMI (southern) property. In 1942, a shipbuilding facility occupied the RCI property, which later was occupied by commercial/industrial facilities including steel and metal fabricating. The NMI property was occupied by gravel crushing and concrete production plants through the 1980s, and for office and storage through 1995; thereafter, it was vacant. In 2003, redevelopment of South Waterfront started.

5.3.1 Aerial Photographs

Historical aerial photographs from 1936 through 2006 were reviewed from in-house files (Army Corps of Engineers), the City of Portland GIS website, GeoDesign (2002a), and Simpson (2004) to document the development of the RCI and NMI properties, on which the Greenway is the easternmost portion. The table below summarizes features and the changes observed on the aerial photographs (descriptions focus on the area between the river and Bond Avenue). These photographs show industrial development occurring primary in the early 1940s within the Greenway and adjoining properties to the west. A shipway was constructed in the southeastern portion of the RCI property in approximately 1942 and was filled between 1963 and 1968. Historical photographs from GeoDesign (2002a) for 1936 through1996 are included in Appendix B.

5.3.2 Sanborn Fire Insurance Map

A Sanborn fire insurance map from 1969 was obtained from EDR for the subject property and surrounding area and was included in previous Phase I ESA (GeoDesign, 2002a). This map is included in Appendix B.

On the RCI property and within the Greenway is a scrap metal yard at the north end and “filled ground”(i.e., the filled shipway) at the south end. Adjacent to the west side of the north end of the Greenway are several buildings for office space, tractor equipment, storage, and welding. To the west, a large building is present in the northwest portion of the property, and two buildings (Electrical Products) surrounded by parking and sign storage in the southwest portion.

On the NMI property is the Pacific Building Materials Company gravel and concrete plant. Within the Greenway are several structures and piers. A notation of “Gas & Oil” is shown in the northeast corner of the RCI property, which relates to the two USTs removed from this area in 1995 (see Section 5.4.2). Descriptions of other features was difficult to discern from the map in the Phase I ESA.

5.3.3 Historical Topographic Maps

Figure 1 uses a 1984 topographic map. The map shows the structures on both the RCI and NMI parcels. Within the Greenway is the electrical tower at the north end and structures associated with the docks and gravel plant.

Hart Crowser Page 21 15663-00 December 20, 2007

5.3.4 Reverse Directories

City directory searches were performed for Phase I ESAs for the RCI and NMI properties using directories from the 1930s through 2000 (GeoDesign, 2002a; Hart Crowser, 1993). Summarizes of the business types occupying these properties is presented in Sections 5.3.1 and 5.3.2 below. Copies of the directory searches from the Phase I ESAs are included in Appendix B.

5.3.5 Public Agency Permits and Records

On-line information from the City of Portland Bureau of Environmental Services (BES) was reviewed for potential USTs and ASTs on or near the subject property (City of Portland GIS, 2007). No USTs or ASTs were found. In GeoDesign’s Phase I ESA for the RCI property (GeoDesign, 2002a), the City of Portland Fire Bureau provided a record for an unspecified 1000-gallon tank located at 3530 SW Bond Avenue (a potential address for the NMI parcel).

The City of Portland Building Records had a April 1966 plan entitled “Plans for New Warehouse and Office Building for Pacific Metals” for the large building observed in the northwest corner of the RCI property in aerial photographs from 1968 through 2003. A February 1958 plan entitled “Plans for Shop and Office Building for Electrical Products Corporation” was located for the building on the southwest corner of the RCI property (visible in aerial photographs from 1961 through 2004).

5.4 Previous Reports

Hart Crowser obtained previous environmental reports from PDC, GeoDesign, Inc., and the DEQ that included the subject property. A summary of information in these reports is presented below, including previous investigations near or on the subject property. Appendix B includes figures and tables of available chemical data for the Greenway. During our search, however, we became aware of other reports that may provide additional information. These are discussed in Section 9.

5.4.1 RCI Property

The subject property north of Pennoyer Street is the eastern portion of the RCI property, or US Bank Site (ECSI #4036). In 2004, DEQ prepared a Staff Report summarizing the history of the US Bank Site, activities performed on the site, and the results and conclusions of these activities (DEQ, 2004). Information from this Staff Report is presented below and is supplemented by other environmental reports, as referenced (see Section 12).

Hart Crowser Page 22 15663-00 December 20, 2007

History. Between 1909 and 1936, the RCI property was vacant with the possible filling activities occurring at various locations. From 1936 through 1944, commercial and industrial facilities were present including a moorage and construction companies (GeoDesign, 2002a). From 1943 to 1945, a shipbuilding facility occupied the property. A shipway was constructed into the southeastern portion of the property beginning in 1942 (GeoDesign, 2003x). It was later filled during the mid 1960s with miscellaneous debris (GeoDesign, 2002a,c).

From the late 1940s to the early 2000s, the property was occupied by commercial/ industrial facilities, including steel and metal fabricating, road construction, general construction and electrical products manufacturing. Pacific Metal occupied the property since approximately 1963, with a large building (Metals USA) constructed on the southeast corner of the intersection of Bond Avenue and Gibbs Street in approximately 1966 (GeoDesign, 2002a). A smaller building was constructed near Bond Avenue and Curry Street in approximately 1958 (GeoDesign, 2002a).

Ownership. All or portions of the property were owned by the Oregon Railway & Navigation Company/Oregon-Washington Railroad & Navigation Company from 1880 to the 1950s. The Page & Page Company purchased the majority of the property from the Union Pacific Railroad Company in 1958 or 1959. From 1961 to 1984, all or portions of the property were owned by Dura Corporation, Electrical Products Corporation, Federal Sign & Signal Corporation and/or Pacific Metal Company. In 1984, U.S. National Bank (US Bank) sold the property to the Pacific Metal Company, and the property was transferred back to US Bank in 1985.

Environmental Assessments. In 1991, Reidel Environmental Services (Reidel) conducted a soil investigation on the eastern portion of the property (GeoDesign, 2002a). During 1999 and 2000, Wohlers Environmental Services, Inc. (Wohlers) conducted several environmental studies on the RCI property including geophysical surveys, soil and groundwater sampling, monitoring well installation, limited site remediation, and groundwater monitoring (GeoDesign, 2002c). In 2002, GeoDesign conducted an extensive environmental study of the property, including sampling the monitoring wells and completing 45 push probes and 44 test pits (GeoDesign, 2003x), and completion of limited removal actions (GeoDesign, 2002d). In 2003, they installed six additional monitoring wells. In 2004, excavation for subgrade parking for The Meriwether condominiums (adjacent to the subject property) was performed (GeoDesign, 2004). Figure 2 shows explorations and wells completed on the subject property. Results of these studies that are pertinent to the subject property are described below.

Greenway Investigation. In 1991, Reidel conducted test pits within the Greenway. Petroleum hydrocarbons were detected in soil in the northeastern portion and southern portions of the site; metals were also present in the central portion (Riedel,

Hart Crowser Page 23 15663-00 December 20, 2007

1991). In 2002, GeoDesign completed test pits within the proposed greenway (i.e., the subject property) as part of supplemental investigation of the RCI property (Hart Crowser could not obtain this report for our review – see Section 9). Fifteen soil samples were collected from the surface and up to 16 feet bgs and analyzed for petroleum hydrocarbons, PCBs, PAHs, and metals. Sample results were generally below residential Region 9 preliminary remediation goals ([PRGs] applicable at that time) or, as in the case of arsenic, typical of background arsenic concentrations. One test pit (TP-33), however, had an elevated lead concentration of 262 mg/kg. This area is discussed separately below. Otherwise, the DEQ concluded in their Staff Report that no further action in the Greenway was necessary.

TP-33 Excavation. As part of Wohler’s investigation of the RCI property in the late 1990s, a test pit was completed at the north end of the Greenway. Analytical results on soil samples from 2 feet bgs indicated the presence of oil-range petroleum hydrocarbons and low levels of PAHs. Follow-up test pits by GeoDesign in this area in 2002 did indicate visual impacts; however, lead was detected at 262 mg/kg at 7 feet bgs in test pit TP-33 (Figure 2). Approximately 18 tons of soil between 6 to 9 feet bgs was removed from this area and as transported for offsite disposal (GeoDesign, 2002d). A confirmation sample from 10 feet bgs had 70.6 mg/kg lead, below DEQ RBCs for residential soil (400 mg/kg). As such, the DEQ indicated no further action was required in this area.

Southeast Corner Excavation. During grading of the greenway area in late 2002, diesel-range petroleum hydrocarbons were encountered in soil between 4 and 7 feet bgs in the southeast corner of the RCI property. The area was approximate 35 feet by 40 feet. Approximately 950 tons of contaminated soil was removed (labeled Southeast Corner Excavation on Figure 2). Four confirmation samples were collected from the base and sides of the excavation. Diesel-range petroleum hydrocarbons were not detected in the four confirmation soil samples (GeoDesign, 2002d). Based on these data, the DEQ concluded in their Staff Report that no further action in the Greenway was necessary.

Subsurface Vault. In the late 1990s, a geophysical survey detected and a test pit confirmed the presence of a buried concrete vault in the northeastern portion of the RCI property (the top of the vault was 2 feet bgs). This vault was located along the west perimeter of the Greenway as shown on Figure 2, and was thought to have been previously used by Zidell Marine (GeoDesign, 2002c). The vault was 10 feet wide, 16 feet long, and 12 feet deep, and was filled with liquid and sludge. The liquid (2,320 gallons) and sludge (25 tons) were removed from the vault, the vault was removed, and petroleum-contaminated soil from the cavity (88 cy) was over- excavated (GeoDesign, 2002c). Petroleum constituents were not detected in any of six confirmation samples from the sidewalls and bottom of the excavation. In 1999, monitoring well MW-3 was installed downgradient of the vault area (Figure 2). No

Hart Crowser Page 24 15663-00 December 20, 2007

contaminants were detected in groundwater from this well. The DEQ concluded in their Staff Report that no further action in this area was required.

Suspected Former Paint Waste Pond. Century West (2000) identified a potential former paint waste pond in their Phase I ESA along the northern property line of the US Bank property, just west of the Greenway. Historical aerial photographs also suggested the presence of a waste pond. A 1943 map for the Zidell facility, also indicated a former sludge basin in this area, in the vicinity of the paint shop (DEQ, 2005a). Environmental assessment of this area on the Zidell property did not detect contaminants above screening criteria in a sludge sample from 6 feet bgs or in groundwater from a downgradient well; as such, no further work is planned for this area (DEQ, 2005a).

Environmental investigation of the suspected former paint waste pond was also conducted on the RCI property. Three push probes and two test pits were completed within the estimated area of the suspected pond. The test pits encountered approximate 6-12 inch thick lens of a non-native white silt material from 3 to 4 feet bgs (GeoDesign, 2002c). Analysis of this material and soil did not detect petroleum or SVOCs. Metals were below risk-based concentrations (occupational direct contact) or typical of background levels. Groundwater samples from probes and a monitoring well downgradient of this area (MW-2 on Figure 2) did not indicate the presence of SVOCs, PCBs, VOCs, or dissolved metals above regulatory cleanup levels or accepted background levels. Based on this data, the DEQ concluded in their Staff Report that no further action in this area was required.

Former Shipway. A shipway was present in the southeastern portion of the RCI property (i.e., Block 30) from 1942 through the mid 1960s. Figure 2 shows this shipway. Environmental activities were conducted within fill placed in this shipway and to the west. Limited amounts of chemical contamination were detected in the area to the west of the subject property. PCBs were detected in two probes (less than 0.15 mg/kg) in samples between 19 and 24 feet bgs. Elevated lead was present in one probe sample at approximately 7 feet bgs, and petroleum was present was detected in samples from several test pits between 5 and 15 feet bgs. These areas were remediated through soil removal in 2002 (GeoDesign, 2002d). In 2004, excavation for two levels of subgrade parking removed most of the soil in this area (Block 30). Sample results from this excavation, including three samples obtained from the shipway, did not detect petroleum hydrocarbons or metals above background concentrations (GeoDesign, 2004). Block 30 has received an NFA letter from the DEQ.

Groundwater Assessments. Groundwater on the RCI property (which includes the Greenway) was evaluated from eleven groundwater monitoring wells and over 45 groundwater grab samples from push probes. The shallow groundwater table is

Hart Crowser Page 25 15663-00 December 20, 2007

present beneath the property at 12 to 25 feet bgs, and generally flows toward the east, ultimately discharging into the Willamette River.

In 1999, Wohlers installed five wells on the RCI property, including 3 wells within the Greenway (MW-2, MW-3, and MW-4). The wells were sampled five times between August 1999 and September 2000 for TPH, volatile organic compounds (VOCs), and metals. Groundwater from MW-4 was also analyzed for PCBs in August 1999. Detections included low levels of TPH and benzene in wells MW-1 and MW-2 in June 2000 (both wells are along the north property boundary of the RCI property; GeoDesign, 2002c); TPH in MW-4 in September 2000; and 8.1 μg/L methyl isobutyl ketone in MW-4 in August 1999. Other or subsequent sampling events did not have detectable levels of these compounds. In 2002, GeoDesign sampled groundwater from these wells for analysis for PCBs, VOCs, PAHs, and metals. Five non- carcinogenic PAHs were present in well MW-4, but at concentrations less than DEQ freshwater aquatic SLVs.

In 2003, GeoDesign installed six wells on the RCI property, three along Bond Avenue and three with Block 30 (MW-10 was near the west perimeter of the Greenway). Groundwater samples from these wells were analyzed for VOCs, PAHs, PCBs, oil and grease, and metals. Detections in wells on Block 30 included acetone at 25 μg/L in MW-10 and five non-carcinogenic PAHs in all of the groundwater samples, of which naphthalene in MW-10 at 0.108 μg/L. Metals were also detected but were consistent with expected background levels and/or below freshwater SLVs (or wells further downgradient were below SLVs).

Based on these data and the remediation of potential sources of contamination to groundwater, the DEQ concluded in their Staff Report that the detections of PAHs and metals are considered stable with no potential to migrate to the Willamette River. The concentrations in groundwater are also considered protective of the Willamette River, and therefore, no further action for groundwater is required.

5.4.2 NMI Property

The subject property south of Pennoyer Street is the eastern portion of the NMI property, or Pacific Richland Site (ECSI #3993). In 2005, DEQ prepared a Staff Report summarizing the history of the US Bank Site, activities performed on the site, and the results and conclusions of these activities (DEQ, 2005b). Information from this Staff Report is presented below and is supplemented by other environmental reports, as referenced (see Section 12).

History. Historically, the NMI property was occupied by gravel crushing and concrete production plants from the 1930s through the 1980s. Ancillary facilities included a paint operation and vehicle maintenance operation. Pacific Building Materials (PBM)

Hart Crowser Page 26 15663-00 December 20, 2007

Company began operating on the property in 1936. In 1958, Readymix Concrete Company also operated on the property. By the late 1960s, both PBM and Readymix Concrete were divisions of Glacier Sand and Gravel. In the mid 1970s, Kaiser Cement and Gypsum and Western Pacific Construction Materials Co. (WPCM) joined the other companies on the property. In 1985, only WPCM was operating on the property. Lone Star Northwest then operated the facility between 1987 through early 1990 (Hart Crowser, 1993). The facility included a concrete batch plant, repair shops and offices, fueling areas, and a wet screen (Parametrix, 2004). The property was then leased for storage and office space until September 1995 (Hart Crower, 2005). In the mid 1990s, Rosebud Holdings (a divestment division of Lone Star) had environmental activities conducted on the property. It was then vacant until construction began recently in 2006. The property was sold, with the current owner being NMI.

Environmental Activities During Operations. In 1993, Hart Crowser conducted a Phase I ESA for the NMI property (Hart Crowser, 1993). Historical records indicated that the facility discharged wastewater to the Willamette River in 1971. In 1972, a waste discharge permit was issued, but it expired in 1973. In 1982, DEQ issued Riedel International, Inc., dba WPCM, a civil penalty for twice discharging untreated wastewater into the river. Also in 1982, visible air contaminants were discharged in violation of their Air Contaminant Discharge Permit. In 1984, a DEQ inspector observed a non-permitted discharge of wash water to the river. On November 21, 1985, WPCM employees reported the spill of 15 gallons of “Zeecon,” an organic substance having a high oxygen demand. The report did not indicate whether the spill was cleaned up.

In October 1986, Riedel International removed a 1,000-gallon diesel UST from the property. No records of soil sampling were found. In 1990, Lone Star Northwest had five USTs removed from the site. All five USTs had soil contamination due to overfilling; one of the USTs also had contamination due to a leak from a pipe fitting. Contaminated soils were excavated and transported off-site for aeration treatment. Confirmation samples from the excavation floors indication TPH results below DEQ’s Level II Soil Matrix cleanup standards (80 mg/kg for gasoline; 500 mg/kg for diesel and oil).

Site Characterization and Remediation Activities. In 1995, Hart Crowser conducted site characterization activities to assess concerns raised in the Phase I ESA (Hart Crowser, 1993, 1995a). Our activities included a geophysical survey, sampling wood from transformer racks, sampling surface and subsurface soils, and installing and sampling groundwater from five monitoring wells (three wells were located within the Greenway, of which MW-1 and MW-2 still exist). Samples were analyzed for petroleum hydrocarbons, VOCs, PCBs, PAHs, and metals. Identified environmental concerns included petroleum-contaminated surface soil, ashy material (material with

Hart Crowser Page 27 15663-00 December 20, 2007

the consistency of ash and concrete chips), residual solids in sumps and an oil/water separator, and diesel-contaminated soil by two USTs and the oil/water separator.

In late 1995, Hart Crowser completed remedial activities to address the identified environmental concerns (Hart Crowser, 1995b,c). Approximately 1,310 tons of contaminated soil and 180 tons of ashy material were removed from the property. Within the Greenway, remedial activities were performed at three locations.

Approximately 150 tons of ashy material was removed at the north end of the NMI greenway parcel. Upon removal, a concrete pad was encountered beneath the material. No confirmation samples were obtained below the pad, as leachable metals testing on the material indicated metals were not mobile.

Two USTs were removed and 840 tons of diesel-contaminated soil were excavated in and adjacent to the northern portion of the NMI greenway parcel. Confirmation samples from the final excavation limits indicated diesel concentrations less than DEQ Level II Soil Matrix cleanup standards (500 mg/kg). (The maximum diesel detection was 180 mg/kg in a sample at 13.5 feet bgs at the east end of the excavation.) A NFA letter was issued by the DEQ on September 4, 1996, for the UST decommissioning (LUST #26-90-0138).

Approximately 240 tons of petroleum-contaminated soil was excavated from beneath a concrete support of the former gravel crushing plant. The excavation was approximately 11.5 feet deep. Analysis of three confirmation samples from the bottom and sidewalls did not detect TPH (detection limit of 20 mg/kg).

Septic Tank and Cesspools. In June 1996, GeoEngineers performed a Phase 1 Environmental Site Assessment Update for the NMI property (Hart Crowser could not obtain this report for our review – see Section 9). They concluded that a septic tank and associated cesspools in the vicinity of the old office building (northwest corner of the property) were the only areas warranting further investigation. Three test pits were excavated to 7 feet bgs. While some samples exhibited some sheen and low photoionization detector readings, analtyical results did not detected petroleum hydrocarbons or VOCs (GeoDesign, 2002b). Based on this data and that the soils would be removed during excavation for Atwater Place, the DEQ concluded in their Staff Report that no further action is needed in this area.

Greenway Investigation. In 2002, GeoDesign completed two push probes and 11 test pits near and within the proposed greenway (i.e., the subject property) as part of supplemental investigation of the NMI property (Figure 2; GeoDesign, 2002b). Field observations did not indicate any petroleum hydrocarbon contamination; however, stained soils were present in TP-29 next to a treated timber pile at approximately 15 feet bgs. Soil samples were analyzed for PCBs, PAHs, and metals. Results detected several PAHs in soil from 13 feet bgs in TP-29, of which

Hart Crowser Page 28 15663-00 December 20, 2007

four PAHs exceeded DEQ RBCs for direct contact. This area is discussed separately below. Otherwise, the DEQ concluded in their Staff Report that no further action in the Greenway was necessary.

TP-29 Excavation. As indicated above, PAHs were detected in soil next to a timber pile encountered in test pit TP-29. Approximately 100 tons of soil was removed from the 13- to 20-foot depth interval in this location and transported offsite for disposal. A confirmation sample from the bottom of the excavation (20 feet) had 0.0501 mg/kg fluoranthene and 0.0434 mg/kg pyrene, below DEQ RBCs for residential soil (GeoDesign, 2002d). Based on these data, the DEQ concluded in their Staff Report that no further action was required.

Groundwater Assessments. Groundwater on the NMI property (which includes the Greenway) was evaluated from five groundwater monitoring wells and six groundwater grab samples from push probes. Groundwater was analyzed for TPH, VOCs, PAHs, and metals. Groundwater at the site has not been adversely affected by site operations and is not expected to adversely affected by the few locations of low level soil contamination remaining at the site. Based on these data, the DEQ concluded in their Staff Report that no further action was necessary.

6.0 SITE RECONNAISSANCE

On September 29, 2007, Mr. Jason Cook of Hart Crowser performed a site reconnaissance of the subject property (the Greenway). In preparation for potential subsurface investigation, a follow-up reconnaissance was conducted on November 7, 2007, by Mr. Rick Ernst of Hart Crowser. Field notes and photographs were taken to document the site reconnaissance findings. Additionally, a walking and drive-by reconnaissance of adjoining and surrounding properties was performed. Appendix A includes representative photographs, with locations and shooting directions shown on Figure 2.

6.1 Subject Property

The subject property comprises two Multnomah County tax parcels, totaling 4.35 acres, and is located in the North Macadam Urban Renewal Area of Portland, Oregon (Figures 1 and 2).

General Conditions. The property consists of grass-covered strip improved with an asphalt-paved walking path, which transverses the property in a north-south direction (Photographs 1 through 3). One or two rows of silt fences were observed along the eastern perimeter of the subject property, oriented in a general north-south direction (Photograph 2). These erosional controls were installed after grading of the Greenway

Hart Crowser Page 29 15663-00 December 20, 2007

to control stormwater runoff from entering the Willamette River. The southernmost portion of the subject property is a bioswale with stormwater outfalls (Photograph 4). The City of Portland has an easement for the bioswale (Rowe, 2004). The bioswale was constructed by creating a ravine, laying gravel and rip rap for surface water flows, and planting riparian-type vegetation on the ravine sides.

Willamette River Bank. The riverbank along the eastern perimeter of the Greenway drops steeply to the Willamette River. The east boundary of the subject property is the ordinary high water line; however, because there is no clear demarcation of this boundary, we are describing the riverbank in this section. The riverbank is covered and/or armored with concrete debris or aggregate (Photographs 5 through 8). Other debris along the riverbank included metal fragments, cables, asphalt blocks, timbers, shopping carts, clothing, and general household-type refuse. Former barge docks were observed in the river along the eastern perimeter of the southern portion of the Greenway (Photograph 7). The footings and sheet piling for a former dock were present in the river off the south end of the subject property.

Outfalls. Four newer stormwater outfalls are present within the bioswale on the southern portion of the subject property (Photograph 9). Surface water runoff from streets in the South Waterfront Central District is directed to one of these outfalls, while the other outfalls likely serve other surface water drainage from adjoining developments. During our site visits, discharge water appeared relatively clear and did not exhibit sheens or odors. An apparently abandoned outfall is located along the riverbank near the central portion, in line with SW Pennoyer Street (Photograph 8). This outfall likely served the RCI property. No water was being discharged from this outfall during our site visits.

Monitoring Wells. During the site visits, three monitoring wells were observed on the subject property. One monitoring well was located along the northern perimeter of the northern parcel, and is well MW-2 installed by Wohlers in 1999. Two monitoring wells are present in the southern portion of the property: one well at south end of the walking path and one well within the bioswale. These wells are MW-1 and MW-2, respectively, which were installed by Hart Crower in 1995. As shown in Photograph 10, the monitoring well at the south end of the walking path was observed to be in poor condition, with the entire monument and casing protruding above grade. The other wells were observed to be in good condition. These wells are also shown on Figure 2, along with other former monitoring wells that were once present (these wells could not be found during our site visits).

Soil Stockpiles. Several small stockpiles were observed on the subject property during the September 29, 2007, site reconnaissance. The stockpiles were observed along the west side of the northern portion of the Greenway (Photograph 1). Fill material/dirt and building material fragments, consisting of cinderblocks, PVC piping,

Hart Crowser Page 30 15663-00 December 20, 2007

wires, wood, cables, and metal were observed. The stockpiles were approximately 5 to 12 feet in diameter and 3 to 6 feet in height. During our November 7, 2007, site reconnaissance, some of the stockpiles had been removed or graded out. The remaining piles consisted of a 1-foot high and 20-foot long gravel and soil pile, and a 4-foot high, 10-foot-diameter sand pile with concrete debris (Photograph 11).

Features Not Observed. During our site visits, we did not observe evidence of USTs, ASTs, drums, pits, ponds, or lagoons on the subject property. With the exception of the stockpiles addressed previously, the upland portion of the subject property was observed to be clear of refuse, trash, or debris at the time of the site reconnaissance. Some metal debris was present at the north end of the Greenway. No indications of hazardous materials dumping were observed along the riverbank.

6.2 Adjoining and Surrounding Properties

During our site reconnaissance, we observed adjoining and surrounding properties for activities or features that might indicate the potential for contamination to the subject property. In summary, we did not observe features on these adjoining parcels that would indicate the possible present of contamination to the subject property.

Zidell Marine is located north of the subject property, and is currently a barge building facility (Photograph 12). In the vicinity of the Greenway were storage of corrugated metal pipes; further away to the west is the paint shop and to the northwest a large building for constructing barges.

Five blocks (Blocks 23, 27, 30, 34, and 37 on Figure 2) are present west of the Greenway. Two condominiums are nearing completion west of the central portion of the Greenway (Photograph 1). The Meriwether is located on the north side of SW Pennoyer Street (Block 30) and has two towers of 21 and 23 stories. Atwater Place on the south side of Pennoyer Street (Block 34) has 22 stories. The two blocks north of The Meriwether are undeveloped and have been graded (Block 27; Photograph 13) and partially excavated (Block 23). A new electrical tower is located near the northwest corner of the subject property for electric lines to cross the Willamette River; lines to the west are underground. Block 37, south of Atwater Place, is being used as construction staging area for Atwater Place. Fences were present along the west side of the Greenway, except for the block with The Meriwether.

The property south of the Greenway is used for staging construction equipment and supplies, and for parking vehicles (Photograph 14). Two outfalls were observed just south of the southern property boundary. No water was being discharged from these outfalls during our site visits.

Hart Crowser Page 31 15663-00 December 20, 2007

Along the east side of the subject property is the Willamette River and riverbank below the ordinary high water line. The riverbank is described in Section 6.2. Barge docks are present along the southern portion of the Greenway. Within the river east of the subject property is Ross Island (Photograph 2), a former gravel mining operation and area slated for open space.

7.0 INTERVIEWS

In preparation of this Phase I ESA, we interviewed individuals knowledgeable about the subject property. Mr. Trevor Rowe of Williams & Dame Development Corporation represents the current owners of the Greenway: RCI and NMI. He informed us of easements on the subject property, the presence of the former shipway and that explorations of this area have been performed, and provided the environment firm (GeoDesign) from which we could obtained reports for and near the subject property (Rowe, 2007). Mr. Van Vickle of PDC was contacted for user- supplied information; his responses are included in Section 4 (Van Vickle, 2007). We also contacted Mr. Chris Kaufman of the Oregon DEQ regarding the regulatory status of the subject property (Kaufman, 2007). He informed us that RCI and NMI properties were within the ICP of the VCS, and of the blocks (25, 29, 30, 34, and 35) of the Central District that had received NFA letters from the DEQ.

8.0 GEOPHYSICAL SURVEY

In October 2007, GeoPotential of Brightwood, Oregon, performed a geophysical survey of the subject property to assess for buried objects and debris. Approximately 4 acres of the subject property were covered; areas overgrown with vegetation, steep slopes, and within fenced construction areas along the west side of the subject property were not surveyed. Appendix D includes a copy of GeoPotential’s report.

GeoPotential performed a magnetic survey (coupled with a GPS system) on traverses of 5 feet across the property. The survey detected numerous magnetic anomalies, which were further explored with an electromagnetic tracer, magnetic gradiometer, and/or ground-penetrating radar. The depth of penetration using these methods was 4 to 5 feet. No USTs were detected by the survey; however, seventeen magnetic anomalies were identified consisting of likely buried demolition debris and/or buried metal. These include the following.

Three anomalies were present within the RCI portion of the Greenway. These anomalies were interpreted to be areas of demolition debris, rebar, and building foundations (one being the former foundation of the electric tower). One

Hart Crowser Page 32 15663-00 December 20, 2007

individual metallic object was identified. This object did not appear to be an UST, although an individual buried drum could not be ruled out.

Three anomalies were present within the NMI portion of the Greenway. These anomalies were interpreted to be areas of demolition debris, rebar, and building foundations. A total of three individual metallic objects were identified, within these anomalies. These objects do not appear to be USTs, although individual buried drums could not be ruled out.

Nine anomalies within the bioswale were indicative of irregular metallic objects, building foundations, demolition debris, and rebar. Three of the anomalies appeared to be concentrated areas of metal debris and/or objects; however, none appeared to be USTs or drums.

Another anomaly within the bioswale appeared to be a small three-dimensional metallic object that may be a buried drum or metallic object.

9.0 DATA GAP ANALYSIS

Reasonably ascertainable information is required to be collected per the ASTM standard and 40 CFR 312. Due to unforeseen circumstances, it is possible that some data gaps may remain at the end of research period. In 2004, Parametrix prepared a Phase I ESA for South Waterfront, which included the subject property (Parametrix, 2004). Historical information in this report was, however, summarized from a previous report (Century West, 2000), which was not available for our review. Through our regulatory file search, we became aware of other reports that were available. Requests for these reports were made to PDC and the current owner representative, Mr. Trevor Rowe; however, they could not be provided. Mr. Rowe suggested that we obtain the reports from their environmental consultant, GeoDesign, Inc., of Portland, Oregon. GeoDesign provided several of the reports. We also obtained several documents from the DEQ and from our in-house files. Several documents, listed in Section 12.2, are still unavailable and may include information and chemical data pertinent to the subject property. Documents that we obtained, however, provide sufficient information to identify potential RECs for the subject property. As such, no significant data gaps were identified.

10.0 CONCLUSIONS

Hart Crowser performed this Phase I ESA in conformance with the scope and limitations of ASTM Practice E 1527-05 for the greenway along the west bank of the Willamette River between SW Gibbs and SW Lane Streets in Portland, Oregon. Based on available information and best professional judgment, the environmental professionals listed below identified RECs, historical RECs, and de minimis conditions

Hart Crowser Page 33 15663-00 December 20, 2007

in connection with the subject property, and have provided recommendations for additional assessment, if warranted. A summary of these findings is presented in Section 1 of this report. Any exceptions to, or deletions from, this ASTM practice are described in Sections 2.2 of this report. In summary, this assessment revealed the following RECs in connection with the property:

The potential for additional localized areas of contaminated soil to exist; and

Possible soil contamination from historical activities, including contamination of soil from previous industrial use of the property, the placement of fill material, and the movement and reuse of these soils as topsoil on the property.

SURROUNDING SITES: SEARCH RESULTS Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

FEDERAL RECORDS CERCLIS-NFRAP: Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site.

An online review and analysis by HART CROWSER, INC. of the CERC-NFRAP list, as provided by EDR, and dated 06/21/2007 has revealed that there are 3 CERC-NFRAP sites within approximately 0.5 miles of the target property.

RCRAInfo: RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act ( RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. RCRAInfo replaces the data recording and reporting abilities of the Resource Conservation and Recovery Information System(RCRIS). The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Conditionally exempt small quantity generators (CESQGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month Large quantity generators generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg of acutely hazardous waste per month. Transporters are individuals or entities that move hazardous waste from the generator offsite to a facility that can recycle, treat, store, or dispose of the waste. TSDFs treat, store, or dispose of the waste.

An online review and analysis by HART CROWSER, INC. of the RCRA-LQG list, as provided by EDR, and dated 06/13/2006 has revealed that there is 1 RCRA-LQG site within approximately 0.25 miles of the target property.

EDR PROPRIETARY RECORDS EDR Manufactured Gas Plants: The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

An online review and analysis by HART CROWSER, INC. of the Manufactured Gas Plants list, as provided by EDR, has revealed that there is 1 Manufactured Gas Plants site within approximately 1 mile of the target property.

Redevelopment of the property for mixed urban residential/commercial uses began in 2004.The larger US Bank site, currently being developed for urban residential and commercial use, had past uses including shipbuilding (1943 to 1945), steel and metal fabricating, and electrical products manufacturing. Blocks 25 and 29 were primarily used for storage of logging equipment and surplus Zidell Marine equipment, and most recently, the site was occupied by a warehouse/office building on the western portion, and associated paved parking and loading docks on the eastern portion.(5/16/05 HBlischke/VCP) Excavation at Blocks 25 and 29 for development was conducted between June and August, 2004, to prepare the site for development. Site investigations identified limited areas of petroleum-hydrocarbon contaminated soil near Blocks 25 and 29. These areas were removed during isolated removal actions as well as during excavation for property development. The excavation was conducted in accordance with the DEQ-approved Soil Management Plan, South Waterfront Central District,Portland, Oregon, dated February 3, 2004 and addenda to the soil management plan. Recent groundwater monitoring events showed contaminant concentrations in groundwater to be below risk-based concentrations and thus do not pose a risk to human health or the environment. Based on this information, DEQ has concluded that Blocks 25 and 29 of the US Bank site does not pose an unacceptable risk to public health or the environment. No further action is required at Blocks 25 and 29 of the US Bank site by current or future owners under Oregon Environmental Cleanup Law, ORS 465.200 et seq., unless new or previously undisclosed information becomes available. Other Blocks within this 17-acre site will be issued no further action (NFA) determinations as the excavations are completed in accordance with the Soil Management Plan and addenda (referred to above).

A small welding shop operated on the site for a short period (unknown) afterward. Eight underground storage tanks (USTs) have been removed from the site, beginning in the early 1990s. In mid to late-1990s the site underwent several environmental investigations and removals of contaminated soils. Summary of reviewed reports indicates over 1,610 tons of contaminated soil has been removed from this property between 1994 to present.Jim Atkins, North Macadam Investors (503) 227-6593 1325 NW Flanders, Portland, OR 97209 New Contact as of 12/28/05: Mr. Trevor Rowe River Campus Investors, LLC North Macadam Investors, LLC c/o Williams and Dame Development 1308 NW Everett Street Portland, Oregon 97209Petroleum hydrocarbons, semi-volatile organic compounds (SVOCs), polynuclear hydrocarbons (PAHs). Contamination has been primarily found in localized areas.Excavation at Block 34 was conducted between November 2005 and March 2006 to prepare the site for development. The excavation activities were conducted in accordance with the DEQ-approved Soil Management Plan, South Waterfront Central District, Portland, Oregon, dated February 3, 2004 and addendums to the soil management plan. Field screening and analytical sampling of excavated soils was used to determine its final disposal destination. A total of approximately 2,825 tons of petroleum impacted material was disposed of at a DEQ-permitted landfill (Waste Management s Hillsboro facility). Five soil samples (Figure 2) were collected at the base of the excavation to evaluate potential to evaluate potential residual contamination. Petroleum hydrocarbons were only detected in one sample (NWTPH Oil-Range hydrocarbons at 128 mg/kg and Diesel-range hydrocarbons at 60.6 mg/kg in S-2-17-06-1 at subgrade). These concentrations are below the DEQ Risk Based Concentration (RBC) for an Urban Residential Receptor and below the RBC for Soil Leaching to Groundwater. Three of the confirmation samples were screened for the RCRA 8 metals. Arsenic was detected at concentrations between 2.83 and 5.19 mg/kg which exceed the EPA Region 9 Residential and Industrial Soil Preliminary Remediation Goals, but are below the Region 9 Soil Screening Level for Migration to Groundwater (29 mg/mg for arsenic). Arsenic concentrations at the site are within the range of background concentrations in Portland area soils (approximately 7 mg/kg as defined in DEQ Toxicology Workgroup memo dated October 28, 2002). Groundwater was evaluated as part of the larger Pacific Richland site and is described in the Pacific Richland DEQ staff report (July 2005). Concentrations of PAHs in shallow groundwater beneath the Pacific Richland site were below DEQ s Level II Screening Level Values (SLVs) and EPA Region 9 PRGs. The levels detected are considered protective of the Willamette River as summarized in the staff report for the Pacific Richland site. Thus, no further action for groundwater is required.

(Project No. 275-1962-009-01-02A) Final Work Plan, Phase II Environmental Site Assessment, Bond Avenue Right-of Way," for Portland Development Commission, by Parametrix, June 21, 2004.(Project No. 275-1962-009) "Phase I Environmental Site Assessment, South Waterfront Plan District, North Macadam Urban Renewal Area," Century West; June 2004.The area of the subject investigation has historically been used as a transportion route to multiple industrial and commercial businesses in this area of southwest Portland. Historic nearby businesses included a lumber mill; a sand and gravel operation that included an asphalt plant (adjacent to east), metal plating (to west); and a 1940’s era shipbuilding operation to the north. This site was evaluated in 2004-2005 by the Portland Development Commission as part of an overall evaluation ofsites throughout the area known as South Waterfront (a.k.a. North Macadam). The work was funded by a Brownfields Assessment Grant awarded to PDC by the U.S. Environmental Protection Agency.The 2004 Phase II investigation revealed petroleum hydrocarbons, metals, polychlorinated biphenyls (PCBs -one sample), and polynuclear aromatic hydrocarbons (PAHs).(6/4/07 CWH/CU&ER) The 2005 Phase II investigation report concluded that the site posed little risk to the public, but recommended that a Contaminated Media Management Plan (CMMP) be developed and utilized during construction.

Requested site specific technical consultation. (6/28/05 HB/ICP) In April/May 2004, approximately 1,800 tons of petroleum-impacted soil were excavated and transported off-site for disposal at a DEQ-approved landfill. Remaining contamination is below risk-based concentrations (DEQ RBCs and EPA Region 9 PRGs) and does not pose an unacceptable risk to public health or the environment.From 1956 to 1995, the property was used for construction materials storage, truck storage, and various warehouse-based businesses. Currently, the property is owned by Trammell Crow Residential and is in the process of being redeveloped for urban residential use.(6/28/05 HB/ICP) Site investigation results showed limited areas of petroleum-impacted soil, but no indication that groundwater has been significantly impacted.

Storage has been the site’s use since the 1970s; it was a machine shop/door manufacturer from 1950s until the 1960s. The property was purchased by the Portland Development Commission for the purpose of constructinga neighborhood park.Low levels of petroleum hydrocarbons, polynuclear aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), and metals in soils. Low levels of diesel-range petroleum hydrocarbons, VOCs, and metals in groundwater.Site impacts likely from past use as machine shop and industrial manufacturing facility. Circa 1950 -1970.Soil and groundwater.Based on what DEQ knows as of Nov. 2005, there are minimal threats to human and ecological receptors.(10/7/05 CK/ICP) Phase 1 and Phase 2 Environmental Site Assessments are complete. Additional investigation will be completed after the site structures are demolished. (2/7/07 MG/CU&ER)DEQ reviewed reports for the site and summarized findings in aFile Memorandum dated December 5, 2006. Based on review of available site information, no further action is required unless additional information becomes available that warrants further investigation.Bunker fuel (mix of diesel and heavy oil hydrocarbons).Dermal contact, ingestion and inhalation of soil.

State tax lots ID 1S1E10DB 0300 and 0400.(10/31/03 CH/SAS) UIC planned for installation adjacent to this property. Site’s historic use indicates that site contamination may exist. (11/1/05 JMW/SAP) Comment period for proposal to add this site to the Confirmed Release List (CRL) ended inOctober 2005, no comments were received.(10/31/03 CWH/SAS) Site was a former asphalt manufacturing plant, the southwest corner of which was used to store trucks. Six underground storage tanks (USTs) have been removed from the property. Historic aerial photographs indicate holding lagoonson the property. The contents of these former lagoons are unknown. (5/18/04, CWH/SAS) Review of existing material shows that in 1989 some petroleum hydrocarbon soils were removed from the site. DEQ LUST program deemed that cleanup warranted an NFA.In 1991, about 1000 cubic yards of diesel contaminated soil was removed from within the "pit" that contained the six USTs. After this cleanup DEQ LUST program deemed that the cleanup warranted an NFA. No investigation of subsurface soils or groundwater beyond the walls of the pit has ever been done to determine if mobile contaminants moved beyond walls of UST pit. Contaminants of concern for the site are petroleum hydrocarbons, metals, polynuclear aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs).a.

Because of the long history of waste disposal activities at this site, and because the site is in an area planned for future redevelopment and high public access, Site Assessment recommends that the XPA be given a high priority. (KPD/SAS) Further action letter sent 5/10/94. (4/95 ELB/VCS) Zidell entered into a Voluntary Letter Agreement on October 7, 1994. A work plan for an expanded Preliminary Assessment was submitted to DEQ in January 1995 and approved in April 1995. Zidell entered into a RI/FS Formal Agreement onApril 13, 1995. (5/7/97 JMA/VCS) Zidell completed the XPA in February 1996. DEQ and Zidell agreed to a Conceptual Site Model and Conceptual Plan for the RI in March 1997. (12/24/97 JMA/VCS) Zidell submitted and DEQ accepted the RI Work Plan in Fall1997. (12/11/01 JMA/VCP) Zidell completed field work to define the nature and extent of contamination in the upland and in-water portions of the facility. Zidell submitted a draft RI report in September 2001, which included the human health baselinerisk assessment. (12/26/02 JMA/VCP) DEQ commented on Zidell s draft RI report, and Zidell is currently finalizing the RI and risk assessments. Zidell submitted a draft Feasibility Study (FS) work plan in May 2002. Zidell is currently revising thedraft FS to resolve DEQ s concerns. [Excerpt from article in The Oregonian, 2/1/05] DEQ is proposing a cleanup plan for the 33-acre Zidell property, which is available for public review. DEQ is seeking public comment on the proposal through March4, 2005. The plan would govern cleanup of the acreage where various Zidell family operations and other companies dismantled ships, salvaged steel, and built vessels for most of the past century. Portland leaders and developers are trying to transform the area into the city’s next urban neighborhood -- a taller, lusher version of the Pearl District, combined with medical research offices and an expansion of Oregon Health & Science University. DEQ s plan calls for capping nearly all of the acreage with three feet of clean soil or buildings to cut off human contact with contaminated dirt. It also calls for removing as much as 8,000 cubic yards of soil from certain hot spots on the tract where asbestos and other contaminants are most concentrated. The Zidell site, at 3121 S.W. Moody Ave., is contaminated with metals, diesel fuel, motor oil and polychlorinated biphenyls, commonly known as PCBs. In addition to the 33 acres beside the Willamette River, DEQ proposes remedial work for about eight acres under the river. According to DEQ, the plan would allow Zidell to develop condos or office buildings on top of contaminated soil in some cases; the buildings themselves would prevent prolonged human contact with the soil, and landscaping would be capped with clean layers of soil. The state’s first priority for cleanup work is the riverbed and 100 feet inland, where the city plans a waterfront greenway for human recreation and wildlife habitat. The work could start as soon as2006.Petroleum hydrocarbons, metals, PCBs and chlorinated solvents.(5/7/97 JMA/VCS) Surface and near-surface soil contaminated with metals, PCBs, PAHs, asbestos, and petroleum hydrocarbons may pose the most significant threat to human health via direct contact, ingestion or possibly inhalation. Exposure to contaminants is restricted by the current site conditions (limited access and asphalt cap over much of the site). Groundwater use in the immediate vicinity of the Zidell property appears limited. The site is adjacent to the Willamette River, which is used for recreation and fishing. Zidell will conduct an ecological risk assessment as part of the RI identifying potential ecological receptors and

Time of release: 1940s to 1980s.Past practice of discharging oil-contaminated water onto surface soils, resulting in oil runoff into Willamette River. Reports of dozens of past oil spills in Willamette River. Past burning practices: burning of wire insulation to recover metal, ignition of oils and greases on metal by welding torches, open burning of debris. Off-site migration of airborne paint and clearing of paint spray guns on riverbank.File Review completed. RI/FS Agreement signed. XPA completed. RI workplan implemented. Draft Beneficial Water Use Determination, Future Land Consideration, and Level I- Scoping Ecological Risk Assessment completed in September 2000.(5/6/97 JMA/VCS) The Zidell property is located in an industrial area that is currently undergoing redevelopment to mixed residential and commercial use. Zidell is also considering redeveloping the property into a similar land use. The Willamette River forms the eastern border of the property. Soil, air, groundwater, surface water (surface runoff), and river sediments may serve as exposure or transport media for chemicals from the property to receptors. A list of possible exposure pathways atthe property includes: direct contact (dermal contact) with contaminated soil, groundwater, surface water, or sediments; ingestion of contaminated soil, groundwater, surface water or sediments; inhalation of volatiles emanating from contaminated soil or groundwater. Many of these possible pathways are restricted by current site conditions (limited access and asphalt cap over much of the site).(1/10/94 KPD/SAS) Zidell Explorations purchased and dismantled World War II-era ships and sold their pieces for scrap. Other site activities included barge construction and the fabrication of tube forgings, fittings, and carbon steel flanges. Shipswere dismantled alongside a dock on the northeast corner of the site. Often the ships would still have various types of oil on-board. Oil was pumped off the ships into portable storage tanks. Literally dozens of oil spills were reported from about 1960 to 1980. Fires also started when welding torches ignited oils and greases on the metal plates. Insulation was burned off wires in incinerators for metal recovery, and debris were burned in open pits on-site and on barges towed to remote stretches of the Columbia River. Transformers may have been salvaged on-site. In addition to the above operations, Zidell enganged in other practices that posed a threat to the environment. No oil-containment booms were in place in the river, only log booms. Oil spills were treated with an "oil sinking" agent. The riverbank was covered with scrap metal, asbestos, fiberglass, lumber, electrical cables and other debris. Ballast water contaminated with oil and sodium dichromate was discharged directly tothe ground. Barges were spray-painted outdoors and there were reports of airborne paint being carried off-site and of personnel cleaning spray guns on the riverbank. Two CSOs are present at the site. (4/95 ELB/VCS) A 1989 investigation detected elevated levels of lead, chromium, PCBs and petroleum hydrocarbons in on-site soils. Chlorinated solvents have been detected in sludges from oil/water separators. Chlorinated herbicides have been detected in groundwater collected from a monitoring wellinstalled downgradient of the former pesticide plant located on the adjoining Schnitzer property. (5/6/97 JMA/VCS) Zidell completed an Expanded Preliminary Assessment (XPA) in February 1996. Further evidence of widespread, relatively immobile, non-volatile soil contamination was encountered during the XPA. Very low levels of a limited number of chemicals of concern were reported in groundwater samples collected during the XPA.(5/7/97 JMA/VCS) CERCLIS File; DEQ ECSI File; EPA 9/87 Preliminary Assessment; Correspondence from owner and/or operator; DEQ Notice of Violation; EPA 7/88 CERCLA Screeing Site Investigation; OMNI 2/89 Site Investigation; EMCON 8/94 Preliminary Assessment; EMCON 2/96 XPA; MFA RI Workplan 10/97; MFA BRA Workplan 9/99; MFA, August 1999, "Scoping Document for

The treated wastewater was discharged to the City of Portland sanitary sewers. Solids were accumulated in an 8,000-gallon tank and pumped out once a year by Crosby & Overton. EPA investigated the site in the early 1980s and determined that no further action under the federal Superfund program was needed, because current waste disposal practices appeared to beadequate.

Prior to its occupancy, Westwood renovated the site building, paved over areas formerly used by the foundry,and installed four fuel USTs on the southeastern side of the property. Several subsurface investigations were conducted between 1985 and 1994, leading to the discovery of petroleum contamination in soil and groundwater around the USTs (which were removed in 1994). Westwood’s contractor prepared a limited risk assessment for the TPH contamination in this area in 1995, and DEQ’s UST Section issued an NFA solely for this portion of the site in August 1996. The UST Section also referred contamination in other portions of the property to Site Assessment. Documented contamination in these other areas consist of diesel-range hydrocarbons in soil near the site’s helicopter pad, and lead in soil at a depth thought to represent the surface of theformer foundry/scrap yard. In addition, borings in the former foundry yard encountered stained soils, "black sand," slag, and brick, which may indicate the presence of heavy metal, hydrocarbon, and PAH contamination in the shallow subsurface. Further, there is historical evidence of a bag house, as well as transformer poles, on the north side of the building, suggesting the presence of heavy metal and PCB contamination in this area.Documents from DEQ’s LUST file #26-93-0128, all from Golder Associates, including: "Phase III Environmental Assessment Property Transfer Report" (1/24/94); "Westwood Corporation Corrective Action Plan" (7/15/94); and "Risk Assessment for Total Petroleum Hydrocarbon Impacted Soil" (12/20/95). In addition, there is a letter report from EMCON, dated 2/9/96, conveying the results of a Beneficial Use Assessment for the neighboring Zidell Waterfront Property (ECSI #689).Petroleum hydrocarbons (mostly in the diesel range), metals, and potentially PCBs and PAHs.Soil and groundwater.Groundwater depth varies between about 8 and 15 feet, depending on the season. Flow gradient is relatively flat, and flow direction is influenced by the level of the Willamette River, located about 500 feet east of the site. Groundwater is likely tobe the primary pathway of concern, especially to the extent that any contaminated groundwater from this site could migrate towards and enter the river. There are a number of wells within a 1-mile radius of the site, but all are used for industrial purposes or cathodic protection, and none is used to supply drinking water. Nearly all of the wells are screened below the water table aquifer.(GMW 2/27/97) Westwood Corporation has conducted no removal or remedial action at the site, but did obtain a limited "no further action" determination from DEQ’s UST Section in August 1996, for the former UST area on the southeastern side of the property.

WESTWOOD CORP. (Continued) S100675848 boring and test pit data collected between 1985 and 1994 suggests the presence of contamination in the shallow subsurface, originating from past foundry and scrap-metal operations. Such contamination would likely consist of hydrocarbons,PAHs, PCBs, and metals, and it may have migrated to groundwater. (Lead and petroleum have already been documented.) The site should be characterized for contamination from these past property uses, which could threaten off-site receptors. Accordingto the Site Assessment Prioritization System, further state action is a medium priority. (4/13/99 ACV/VCP) RP to submit workplan to address data gaps in Spring 1999.

Some of the contamination was related to USTs, which was investigated under DEQ’s LUST Section (log # 26-96-337). The remainder of the contamination is located at the interface between artificial fill deposited during the 1960s and the original ground surface. This non-UST-related contamination consists of heavier, oil-range hydrocarbons that the property owner’s consultant believes to have originated from biogenic sources such as wood waste from the site’s former use as a lumber mill. The consultant has also indicated that some hydrocarbon detections could have resulted from the remains of a pier that burned atthe site prior to the importation of fill. Groundwater at the site contains low levels of PAHs.Reports and correspondence contained in DEQ LUST file #26-96-0337; letter report from GeoEngineers, dated 11/8/96, which includes a 1/93 Phase I report that GeoEngineers had prepared on the property.Oil-range hydrocarbons, PAHs.Subsurface soils (beneath fill), groundwater.The site is located along the west bank of the Willamette River, and its relatively level grade is artificial. Groundwater occurs at depths of about 8 to 15 feet, and flows into the Willamette. Groundwater-to-surface water is likely to be the primary pathway of concern.(2/27/97 GMW/SAS) DEQ’s UST Section issued an NFA for tank-related issues 10/3/96, following the excavation and treatment of approximately 150 tons of petroleum-contaminated soil. The UST NFA letter included a referral to Site Assessment, due to thepresence of contamination that did not appear to have resulted from USTs. Site Assessment has concluded that a PA should be completed to document the site’s industrial history and operations, and to evaluate potential exposure pathways. Due to the site’s location and the low levels of contamination documented as of 11/96, further state action at the site is a low priority.

Shorter-term issue relates to remedial action implementation.South Waterfront between Marquam and Ross Island bridges. Zidell property borders to south and east.Releases were associated with operations at the site. Releases occurred over a long period of time and were associated with company operations - see Contamination below.Pathway of concern is groundwater and discharge to surface water (Willamette River). Direct contact with soil contamination was primary concern that drove much of the remedial work. The site is currently fenced and both units are currently inactivealthough some construction has occurred on Unit A related to the City of Portland’s CSO project including

OHSU - MOODY AVE. UNITS A, B, C (Continued) S105680841 piping installation.(3/15/05 DAB/SRS) Unit A: Unit A Record of Decision was signed by the DEQ Director in April 1995. The remedy includes removal of surface and near-surface soils that exceed remedial action levels, and long-term management of H2S gas (Phase I), and site capping (Phase II). Phase 1 was completed in December 1995. Unit B: Unit B was issued a no further action based on a review of conditions at this parcel. Unit C: Unit C Record of Decision was signed by the DEQ Director in October 1993. The remedy includes removal of on-site, near-surface soils exceeding remedial action levels (Phase I) and site capping (Phase II). Phase I of the remedial action has been completed. Phase II for both Units A and C were initiated with submittal of the DraftPhase II work plan in July 1997. Development of the site has not occurred due to uncertainty with plans for the site. In June 2004 the property was transfered to OHSU from Schnitzer Corporation. OHSU was given an extension on an annual basis forcompletion of Phase II of the remedy due to the change in ownership. OHSU must submit an annual report describing development activities. OHSU will be discussing initial actions to cap the site in early 2007. A parking lot has been placed on UnitB which was given a no further action in the early 1990s so the actions on that Unit are not covered under the Records of Decision for the site.Pesticides: DDT, DDE, DDD, chlordane, aldrin, endrin; and PAHs.Phase I of remedial action for Units A and C is complete. Phase II for both units includes site development. OHSU will complete Phase II as new property owner. The site remains fenced.

PDC requested VCS oversight of the roadconstruction to the extent necessary to determine whether the road would exacerbate existing contamination or would adversely impact future remedial alternatives at the site.Heavy metals, volatile and semi-volatile organics, PCBs, and petroleum-related constituents.The SW Moody Avenue Extension is on the west bank of the Willamette River and north of the . The road runs adjacent to and south of the South Waterfront Redevelopment Area (ECSI site #602) that DEQ has been investigating since 1988.Little is known about the immediate vicinity of the road south of the South Waterfront site. Preliminary assessments have not been conducted on properties adjacent to and east and west of the road extension.The entire area was originally marshy and has been filled with industrial fill since the early 1900s.(2nd Qtr/93 MMD/VCS) Under a Letter Agreement, PDC and its consultant worked with VCS to develop a strategy for sampling soils within the right-of-way and along the length of the road extension as storm and sanitary sewer lines were placed. Becauseof construction schedules and contract demands, PDC determined that there was insufficient time to evaluate potential impacts to groundwater. The road design was modified to mitigate impacts of potentially contaminated soil and groundwater. Cement plugs were placed at selected intervals in the roadbed to prevent potentially contaminated groundwater from migrating along the preferential path the utility trenches were now providing. By the installation of these plugs, VCS determined that the road would not exacerbate existing contamination. Soil sampling and analysis detected the presence of elevated concentrations of petroleum product and lead in isolated pockets along the right-of-way. VCS informed PDC that this soil must be removed to health-based concentrations in order to establish that the road would not adversely impact future remedial alternatives. PDC determined that additional removal, sampling, testing, and data analysis would require more time and resources then they hadfor this project. PDC elected to terminate VCS oversight and retained RZA AGRA to continue investigation on a smaller scale, documenting soil conditions as the roadway construction continued.petroleum, PAHs, metals OR ECSI ECWQ: Owner Site Num: 132717 FACA ID: 8870 Site Name: SW Moody Ave. - Right-Of-Way Owner Name: SW Moody ST - Right-Of-Way Owner City,St,Zip: Portland 97201 Owner County Code: 26.00 Lat/Long: 45.5058 / -122.6736 Owner Code: SUS OR ECSI SITE CONTROL: Site Control #: Not reported Control Number: Not reported

Concentrations heavy oil was not detected. Soil samples FL-#5-SW-13 and FL-#13-S-10 were also analyzed for VOCs, PAHs, and total lead. Concentrations of VOCs were detected in both samples at levels ranging from 0.753 mg/kg to 511 mg/kg. Concentrations of PAHs were also detected in both samples at levels ranging from 0.0193 to 34.6 mg/kg. Total lead was not detected in either sample. About 50 cubic yards ofPCS was left in place following the completion of the pump island excavation. The PCS is located between about 9 feet and 12 feet bgs. Confirmation samples collected from the final extent of the pump island excavation, including those collected inthe area of the remaining PCS, were all less than RBCs for applicable pathways. If this remaining PCS is encountered during the construction of the lined storm water treatment facility, the material will be characterized and transported off-site fordisposal. Based on the leachable lead concentration (24.3 mg/L) from a pre-excavation soil sample, about 64 tons of soil characterized as a hazardous waste was excavated from the vicinity of the former waste oil UST and transported to ChemWaste sfacility in Arlington, Oregon. The excavation extended to an approximate depth of 7 feet bgs. Five confirmation soil samples were collected from the final extent of the excavation and analyzed for gasoline, diesel, and heavy oil. Gasoline, diesel, and heavy oil were not detected. Select confirmation samples were also analyzed for PCBs, VOCs, total metals: lead, cadmium, and chromium. No PCBs or VOCs were detected in the three samples analyzed. Total lead (11.7 mg/kg to 112 mg/kg), total cadmium (3.22 mg/kg, 3.56 mg/kg), and total chromium (19.8 mg/kg to 28.9 mg/kg) were detected in the three samples analyzed. The waste oil UST excavation was successful in removing PCS. The detected concentrations of total metals: lead, cadmium, and chromium were less than respective industrial PRGs. A hydraulic hoist was decommissioned by excavation and removal. Three confirmation soil samples were collected from the final extent of the excavation and analyzed for gasoline, diesel, andheavy oil. Diesel and heavy oil were detected in one of the confirmation samples at 94.7 mg/kg and 446 mg/kg, respectively. Gasoline was not detected in the three soil samples. Two of the confirmation samples were also analyzed for PCBs, VOCs, andtotal metals: lead, cadmium, and chromium. Total lead (11.3 mg/kg, 208 mg/kg) and total chromium (20.3 mg/kg, 28.2 mg/kg) were detected. No PCBs, VOCs, or total cadmium was detected. One

GULL SERVICE STATION (FORMER) (Continued) S106044934 confirmation soil sample was also analyzed for PAHs, and it contained PAH levels ranging from 0.0953 mg/kg to 2.12 mg/kg. Benzo(a)pyrene (1.46 mg/kg) and dibenzo(a,h)anthracene (0.402 mg/kg) exceeded their respective occupational RBCs for the soil ingestion, dermal contact, and inhalation pathways, but didnot exceed their respective construction and excavation worker soil ingestion, dermal contact, and inhalation pathways. All other detected compounds associated with the hoist excavation were less than applicable RBCs or PRGs. The elevated concentrations of PAHs are located about 4 feet bgs, limiting the potential for contact by occupational workers. A no further action determination is proposed for the former Gull Service Station #50 site, and will be finalized after consideration of publiccomments. The final decision will be applicable to both the LUST and ECSI files. (12/12/05 KJR/ICP) No public comments were received. DEQ issued the No Further Action determination 12/5/05.(12/9/03 KJR/VCP) The site was a gasoline service station for an unknown period of time until the early 1980s when all facilities were removed. As part of the MLK Jr Blvd Viaduct project, ODOT performed Phase I/Phase II site assessments at the property. During the Phase II site assessment, waste oil and gasoline contamination was identified in soil. A geophysical survey suggested the presence of a small UST, suspected to contain heating oil, and another small UST suspected to contain hydraulic oil for the hoist. Material within catch basins was sampled and found to contain contaminated sediment. Groundwater was not encountered to the total explored depth of 38 feet below grade. (9/27/05 KJR/VCP) A site investigation that included a geophysical survey, drilling and sampling was performed in November and December 2002. The geophysical survey indicated a possible UST on the east side of the building foundation (a UST was not located during later excavation activites) and apotential hydraulic oil tank near the hoist. A site map showing the former site layout and soil boring locations is included as Figure 2. A total of 18 borings were installed utilizing direct push technology (DPT) drilling equipment. Soil samples collected from 17 of the 18 soil borings were analyzed for hydrocarbon identification. Of the 24 soil samples analyzed for hydrocarbon identification, gasoline and diesel were identified in two soil samples (GPG16-S3, GPG14-S2) and gasoline, diesel, and heavy oil were identified in one soil sample (GPG3-S4). These three soil samples and six additional soil samples were analyzed for gasoline-ranged hydrocarbons and for diesel and heavy oil-ranged hydrocarbons. Concentrations of gasolinewere detected in four of the nine samples analyzed at levels ranging from 11.6 milligrams per kilograms (mg/kg) to 834 mg/kg. Concentrations of diesel and heavy oil were detected in one soil sample at levels of 2,930 mg/kg and 14,800 mg/kg, respectively. Six soil samples were also analyzed for VOCs. Concentrations of one or more VOC compounds were detected in soil samples GPG3-S4 and GPG14-S2 at levels ranging from 0.146 mg/kg to 6.03 mg/kg. Two soil samples (GP14-S2, GPG15-S4) were alsoanalyzed for total lead. Total lead was detected at 9.74 mg/kg and 6.51 mg/kg. The soil sample collected from the vicinity of the former waste oil UST (sample GPG3-S4) was analyzed for leachable cadmium, chromium, and lead. A concentration ofleachable lead was detected at 12.8 mg/L. Leachable cadmium and chromium were not detected. The sample was also analyzed for PCBs. PCBs were not detected. Sediments within two catch basins were analyzed for hydrocarbon identification, dieseland heavy oil, PCBs, VOCs, and SVOCs. The sample from the southern catch basin was also analyzed for gasoline. The following compounds were detected in the southern catch basin sample: gasoline (1,720 mg/kg), diesel (22,000 mg/kg), heavy oil (58,200 mg/kg), PCBs (11.05 mg/kg), VOCs (ranging from 1.44 mg/kg to 72.1 mg/kg), and SVOCs (50.6 mg/kg, 471 mg/kg). The following compounds were detected in the northern catch basin sample: diesel (1,770 mg/kg), heavy oil (4,850 mg/kg), and PCBs (0.263mg/kg). In February 2004, additional site investigation was performed to further define areas of concern identified

Following the completion of the investigation, the consultant provided DEQ with a site map showing the boring locations and a table summarizing soil analytical results. A report was not completed to document the results of the site investigation since a settlement agreement was reached between the property owner (at the time) and ODOT shortly following the completion of field work. ODOT assumed responsibility for cleanup as part of the settlement and the former property owner terminated their VCP agreement with DEQ. A review of the data tables indicated results are consistent with site conditions documented during ODOT s 2002 investigation.(12/9/03 KJR/VCP) The RP joined the ICP. Proposed work includes additional assessment and evaluation to applicable risk standards in the pump island gasoline contamination area, soil excavation in the waste oil area, decommissioning of the heatingoil and hydraulic oil USTs (if present), and cleaning of the catch basins. (9/20/04 KJR/VCP) ICP agreement terminated with RP. New agreement will be entered into with new property owner - ODOT. (9/27/05 KJR/VCP) In April 2005, ODOT excavated and transported off-site for disposal about 460 tons of PCS. During the removal action, the two catch basins and a hydraulic hoist were also excavated and removed. The removal action was performed in three distant areas; the former pump island area, the former waste oil UST area, and the hydraulic hoist removal. Groundwater was not encountered in any of the excavations. The site is scheduled to be developed into a lined storm water treatment facility in 2006. The site may also be incorporated into the City of Portland s combined sewer overflow project. Based on the current and anticipated future use, the residential pathway is not a complete pathway. Since groundwater was not encountered on-site or on nearby sites at depths lessthan 50 feet bgs, the leaching to groundwater pathway is not complete. The following pathways were retained for evaluation. Soil - Occupational Volatilization to Outdoor Air Soil Occupational - Ingestion, Inhalation, and Dermal Contact Soil - Construction & Excavation Worker Ingestion, Inhalation, and Dermal Contact The pump island area was excavated to a total depth of 20 feet bgs. Following the completion of the pump island excavation, 13 confirmation soil samples were collected and analyzed for gasoline, diesel, and heavy oil. Concentrations of gasoline were only detected in two confirmation samples (FL-#5-SW-13 , FL-#13-S-10 ) at levels of 4,440 mg/kg and 609 mg/kg, respectively.

In the first half of the 20th century, the Portland Lumber Company stored lumber piles on the site. From the late 1950s through the 1970s, scrap steel from the neighboring Schnitzer property (ECSI #875) was stockpiled on-site. Finally, between 1994 and 1995, petroleum-contaminated soils were stockpiled on-site during construction of Moody Avenue. In September 1997, PDC (the Portland Development Commission), which had acquired the site, conducted a Phase I Environmental Site Assessment at the site. Additional site characterization and a Preliminary Endangerment Assessment were completed in May 1998. The additional site characterization included soil borings, testpits, and GeoProbe holes. The studies identified petroleum hydrocarbons, polynuclear aromatic hydrocarbons (PAHs), and heavy metals in the soil. Approximately 30 cubic yards of contaminated soil were removed from the site. PDC PDC also applied to DEQ’s Voluntary Cleanup Program (VCP) in June 1998 for review and oversight of its investigation. (This site was originally designated as Lot #5 of the South Waterfront Redevelopment Area. See ECSI #602 for more information.)Phase I Environmental Site Assessment (9/97). Site Characterization, Preliminary Endangerment Assessment and Hot Spot Removal (5/98). Remedial Investigation (1/00). Soil Management Plan (1/00).Diesel and heavy-oil-range petroleum hydrocarbons; carcinogenic and noncarcinogenic PAHs; metals, primarily lead.SW River Parkway & Moody Ave.Past operations of the Portland Lumber Company and Schnitzer may have resulted in petroleum releases. Undocumented fill material may contain contaminants.The site is bordered by the Marquam Bridge to the south and the Willamette River to the east. The RiverPlace development to the north and west is a mix of commercial and high-density residential properties. Groundwater has not been significantly impacted, and the hotel serves as a cap for the remaining contaminated soil.(10/1/2001 TER/VCP) The PDC began work on a remedial investigation at the site in September 1998. As part of this investigation, three monitoring wells were installed at the site. In November 1999, InnVentures, doing business as Portland RiverplaceLLP, signed a Prospective Purchaser Agreement (PPA) with DEQ. InnVentures agreed to purchase the site, complete the investigation and cleanup, distribute approximately $1 million to the City of Portland for park development, and construct a 250+ room Residence Inn by Marriott at the site. In return, DEQ would limit InnVentures’ future liability for pre-existing contamination at the site. The PDC completed a draft Remedial Investigation report for the site in January 2000. DEQ determined that no additional cleanup was necessary, because groundwater was not significantly impacted, and the proposed hotel would serve as a cap for the remaining soil contamination. After ensuring that soil removed from the site during construction was properlymanaged and disposed of (the hotel was completed in June 2001), DEQ issued a No Further Action (NFA) letter for the site in September 2001.

Petroleum hydrocarbons are present from past practices.Deed Notice 6/13/94 for asbestos(7/6/05 TER/VCP) Portland Development Commission is proposing to remove the buried asbestos debris prior to site development as part of an EPA Brownfields grant. PDC completed a feasibility study to assess options for management of the asbestos debris.(10/19/05 TER/VCP) The project file for ECSI #602, the original South Waterfront Redevelopment Area, contains background information, actions, and narratives but has been divided into six sites in ECSI based on changes in tax lot boundaries, differences in development, ownership, and long-term management requirements. Those sites are: #602 South Waterfront Redevelopment Area, Parcel 1 - the former Lincoln Steam Plant, orginally titled Area D, Parcel 3A. It is now The Strand condominium towers, Tax Lot 101. #4420 South Waterfront at RiverPlace, Parcel 2 Areas B&C - Stanford’s restaurant, RiverPlace Square apartments, retail space and associated parking structure, Tax Lots 500, 600, and 1200. #4421 South Waterfront at RiverPlace,Parcel 2 Area A - SW River

Also see ECSI #2232 InnVentures, (Lot 5) and ECSI #2492, South Waterfront Lot 3, for adjacent site information. In 1988, the Portland Development Commission (PDC) entered into a Voluntary Agreement with DEQ to conduct a Remedial Investigation and Feasibility Study (RI/FS) at the "South Waterfront Redevelopment Area" site. For purposes of the investigation, the property was divided into Parcels 2 and 3. Parcel 3A was the site of the former Lincoln Steam Plant. In October 1989, after completion of the first phase of the investigation, DEQ approved a PDC proposal that would allow roads and structures constructed on Parcel 2 to function as a protective cap. Parcel 2 Areas B&C were developed and purchased by Trammel Crow Residential in 1994. DEQ issued a No Further Action for Parcel 3B in 1994, a portion of which was developed as the "PGT building." The RI/FS for Parcel 3A was completed in 1998. South Waterfront Park resulted from improvements for extension of a greenway along the waterfront. Parcel 3A (now Parcel 1) will be developed as condominium towers. PDC will address asbestos on the undeveloped portion of Parcel 3B (Lot 8) for future redevelopment.SoilAir (if overburden is removed and cement coating containing asbestos were disturbed).Inhalation of asbestos.

DEQ has no information to indicate that the ultimate fate of rainwater that accumulates in the depression on the southern 1/3 of the site has ever been defined. At least five stormwater sumps are located around the perimeters of the two southern tank pads (see Figure 5a), but DEQ cannot ascertain from existing City of Portland whether the sumps are connected to the municipal stormsewer system (see Figure 11). Ponded water in or neartwo of the sumps contained elevated concentrations of total cyanide (up to 120 ppm) and TCLP leachable lead (up to 12 ppm) when sampled in March 1991 and April 1992. A stream that historically crossed the southern 1/3 of the site (in 1909) was evidently directed to a sewer on the site s western property line (see Figures 14 and 16). Readily-available records from the city of Portland do not indicate whether this sewer was ever fully abandoned, or if it may discharge to the existing municipalstormsewer. A monitoring well that the City of Portland constructed in the street near the site s southwest corner in March 2001 encountered groundwater at 21 feet bgs (see well MW-10 in Figure 17); the depression on the southern 1/3 of the site,where the two southern tank holder pads are located, is as much as 20 feet below the surrounding grade (see Figure 10). Contamination associated with the former gas holder tank pads could easily extend into shallow groundwater. The site is located within an Environmental Justice area (see Figure 20), a year 2000 US Census Block (Block 3 of Census Tract 11.02) where more than 31-percent of the population lives below the national poverty level. Environmental Justice areas are considered Site Assessment Vulnerable Areas for the purposes of Site Discovery. The Willamette River is located about 0.25 mile west of the site (see Figures 1 and 2). Stormwater sewers at the southern and western boundaries of the site discharge directly to the river, near River Mile (RM) 14.0. Contaminants reaching this part of the river could contribute background sediment contamination to Portland Harbor (ECSI #2068), a federal Superfund site located 4 miles downstream. Below Willamette Falls (RM 26.6; at Oregon City), the Willamette River is considered part of the Lower Columbia Estuary, another Site Discovery Vulnerable Area. In 2002, the lower 24.8 miles of the Willamette River (downstream from the mouth of the Clackamas River) wasincluded on DEQ s 303(d) list of Water Quality Impaired surface water bodies because of elevated stream temperatures, elevated fecal coliform bacteria counts, fish skeletal deformities, elevated concentrations of iron, manganese, PAHs, and DDT in the water column, elevated concentrations of pentachlorophenol in river sediments, and elevated concentrations of mercury, PCBs, aldrin, DDE, DDT, and dieldrin in the tissue of fish caught from the river. Surface water bodies that have been includedon DEQ s 303(d) list because of toxics contamination are also

PORTLAND GAS & COKE GAS HOLDER TANKS (FORMER) (Continued) S106980974 considered Site Discovery Vulnerable Areas (see Figure 20). In November 2001, the Oregon Health Division (OHD) issued a consolidated Health Advisory (HA) regarding consumption of fish caught from the Willamette River, because of elevated concentrations of mercury, PCBs, dioxins, and chlorinated pesticide residues detected in the tissue of fish caught from the river. Surface water bodies for which OHD has issued Health Advisories for potential consumption of contaminated fish or shellfish comprise another category of Site Discovery Vulnerable Areas (see Figure 20). Darigold, Inc., a wholesale manufacturer of dairy products for human consumption, owns a 16-inch diameter, 450-foot deep industrial well and associated Certified Water Right Claim, located about 550-feet west of the contaminated area. The well casing is perforated beginning at 105-feet below ground surface, and appears to withdraw groundwater from theunderlying Troutdale and Sandy River Mudstone formations. There is concern that potential groundwater contamination at the subject site could reach the Darigold well, and possibly contaminate food products for human consumption, or represent a potential risk for Darigold workers.The site is likely to be used long term as industrial land. It is located in an area of mixed industrial, commercial, and residential properties (see Figure 19). All properties immediately surrounding the site are either commercial or industrial use, as are more distant properties to the west, northwest, and southeast. However, residential areas are located south of SE Powell Boulevard, east of SE 12th Avenue, and north of SE Division Street. The nearest residential properties are locatedabout 215 feet north, 290 feet east, and 490 feet south of the site (see Figure 18).Site contamination is believed to have been predominantly associated with releases of condensate from stored manufactured gas, or through other historic gas handling practices. Minor subsurface contamination may be associated with incomplete cleanup of releases from leaking underground petroleum storage tanks and associated transfer piping, or from tank overfills. Some subsurface contamination may be associated with materials that were used historically to bring the northern 2/3 of the siteup to its current elevation. It is not known if more recent surface spills of vehicle maintenance chemicals or other stored chemicals may have occurred, and reached the subsurface through the site s drywells.Surface soils, subsurface soils, ponded surface water, and probably shallow groundwater.DEQ Site Assessment reviewed existing information about the site in January 1994, and assigned it a low priority for further investigation and cleanup. Site Assessment re-examined the site s priority for further investigation and cleanup in 2006 based on new information about the local depth to shallow groundwater, information about site drywells and chemical storage at the site, and recent city plans to construct a new stormwater collection and storage system along the river s eastern bank. Based on the 2006 Site Assessment review, a high priority has now been assigned to further investigation and cleanup of remaining site contamination.PAHS, lead, cyanide, and possibly other metals, volatile organic compounds (VOCs), and phthalates.Well records at Oregon Water Resources Department (OWRD) and the U.S. Geological Survey (USGS) indicate that groundwater within the nine survey sections (9 square mile area) surrounding the site is predominantly used for industrial purposes, althougSandra Hart, Director of Risk, Environment and Land 220 NW 2nd Avenue, Portland, OR 97209-3942 (503) 226-4211 Conrad J.

PORTLAND GAS & COKE GAS HOLDER TANKS (FORMER) (Continued) S106980974 hazardous waste due to elevated concentrations of leachable lead and cyanide. Approximately 19,000 gallons of cyanide-contaminated water within the three gas inlet vaults at the site s eastern gas holder tank pad (Pad #7) was discharged to the city sanitary sewer in August 25 to September 3, 1993. 49 tons of petroleum-contaminated soil excavated during cleanup of the site s various leaking petroleum underground storage tanks (LUSTs) was sent to Oregon Hydrocarbons in 1994 for treatment. 32 tons of contaminated soil was sent to Marion County Soil Recycling in 1995 for treatment.The northern 2/3 of the site is covered either by buildings or blacktop-paved parking areas (see Figure 3). Ordinarily, these surface features would minimize rainwater infiltration or escape of potential subsurface organic vapors. However, the site also has 13 active (and one inactive) drywells beneath the parking areas, fed by an equal number of on-site stormwater catchbasins (see Figure 10). The drywells are 4 feet in diameter, and nominally measure 24 feet deep. Stormwater discharged into the drywells could mobilize subsurface soil contaminants. At least some of the drywells are likely to intercept the shallow groundwater table: A City of Portland monitoring well constructed in the right-of-way near the intersection of SE Taggart and Clinton Streets encountered groundwater at 21 feet bgs (see Figure 17); the depression on the southern 1/3 of the site is up to 20 feet deep (see Figure 10). The drywells and associated catchbasins could also allow venting of potential subsurface volatile contaminants. The site is securely fenced, so access to unauthorized pedestrians and potential trespassers should be negligible.NNG removed contaminated waste piles, some of the contaminated debris, and some of the contaminated soils associated with the site s two southernmost concrete gas holder tank pads through an independent cleanup action in 1991-92. However, soils with lower levels of contamination, contaminated soils that were inaccessible, much of the contaminated debris and water within capped and abandoned gas transmission piping, contaminated water and debris within stormwater sumps surrounding the pads, and contaminated water within that pad s gas inlet vaults were left in place. Minor contamination also remains in subsurface soils surrounding the site s former LUST locations, and along fuel piping that was abandoned in place. The full characterand vertical and horizontal extent of subsurface soil contamination, and potential groundwater contamination, have not been determined. There is also no record to indicate that subsurface soils and groundwater have ever been examined at the locatioh a few domestic and irrigation wells are also present. Within the nine square mile area (approximately equivalent to a 1.7 mile radius), there are 44 industrial wells (83 ), 4, irrigation wells (8 ), and 5 domestic wells (9 ). The nearest domestic wells are three domestic wells (53- to 74 feet deep) located approximately 1.65 mile southeast of the site, in a presumed upgradient location. The nearest industrial well is a 490-foot deep well at the Darigold, Inc. facility, approximately 550 feet west of the site (see Figure 18). The well was constructed in 1946, and penetrates fill (0-12 feet bgs), fluviolacustrine deposits (12-43 feet bgs), Troutdale formation (43-258 feet bgs), and Sandy River Mudstone (below 258 feet, bgs).The well has an associated Water Right claim, certified in 1960, which states that the well was in continuous use since it was first constructed. Although the well log for this well provides no well construction details, the associated Water Rightregistration form indicates it has a 16-inch diameter casing from the ground surface to 450 feet bgs; the casing is perforated from 105- to 425 feet bgs (in the Troutdale and Sandy River Mudstone formations). The Darigold facility (Darigold / LandO’Lakes / Purina / Concentrates, Inc.) is a wholesale distributor of dairy products for human consumption, and a manufacturer of livestock feeds, pet foods, and organic garden-soil amendments. OWRD also has a well log for the deepening of an industrial well at the Irwin-Hodson Company, adjacent to the subject site s southern boundary. In 2005, Cascade Environmental Services reported that this well s casing had been backfilled

The Willamette River, which lies about 0.25 miles (1,385 feet) west of the site, is used for recreational fishing, boating, and swimming, as well as providing critical rearing and migration habitat for Threatened and Endangered salmonid species. The river also likely provides an important food source for bald eagles.A 1909 Sanborn Fire Insurance Map depicts the subject site as vacant, low-lying land with a creek flowing southeast to northwest, across the southern third of the site (see Figures 14 and 16). A notation on the 1909 map indicates that the creek entered a sewer at the site s western boundary, along SE 9th Avenue (see Figure 14). Other pages from the 1909 Sanborn suggest that the creek may have historically followed a northwest trending gulch that paralleled the southwestern edge of a Union Pacific Railroad mainline right-of-way. Prior to July 1958, Northwest Natural Gas Company was known as Portland Gas & Coke Company. The site s manufactured gas holder tanks were constructed in 1921-1925. A 1924 Sanborn Fire Insurance map depictstwo, 2 million cubic foot, gas holder tanks and several gas compressor houses located on a property owned by Portland Gas and Coke Company (see Figure 13). The site appears to have been used primarily for gas storage and transmission. A 1950 Sanborn Fire Insurance map (see Figure 12) shows the same tanks and compressor buildings, plus an additional 3+ million cubic foot gas holder tank added near the southwest corner of the site. There are no indications that gas was manufactured at the site. Recent air photos show a large paved parking area and various buildings on the northern 2/3 of the site (see Figure 3), with two tank footprints located in a depression on the southern 1/3 of the site. Vehicles are parked on circular paved surfaces in the bottom of the depression (see Figures 3 and 18).Northwest Natural Gas Company 220 NW 2nd Avenue Portland, OR 97209-3942 503-226-4211The site is located in southeast Portland, four blocks east of the eastern terminus of the Ross Island Bridge, and two blocks north of SE Powell Boulevard (US Hwy 26) (see Figures 1 and 2). State Highway 99E (SE Grand Avenue) is four blocks west ofthe site. The Willamette River lies 0.25 mile west of the site. The site is bounded on the south by SE Taggart Street, on the southeast by SE Clinton Street, on the west by SE 9th Avenue, on the east by SE 11th Avenue, and on the northeast by a Union Pacific Railroad mainline right-of-way (see Figure 2). An alternative site address is 905 SE Division Street.Surface soil contamination, and potential subsurface soil and shallow groundwater contamination, could represent a potential ihhalation or direct contact threat, or potential vapor intrusion threat to on-site workers, or potential vapor intrusion threat to off-site workers at the nearby Irwin-Hodson facility, or at other nearby commercial and industrial facilities. Potential subsurface contamination could also represent a threat to on-site, and nearby off-site, utility trench workers, construction workers, or to stormsewer utility workers. Potential groundwater contamination at the subject site could reach the nearby Darigold, Inc. production well, and possibly contaminate food products used for human consumption, or represent a potential risk for Darigold workers. Residential neighborhoods are located as near as 215 feet to the north, 290 feet to the east, and 490 feet to the south of the site. A Buddhist temple is located about 290 feet east of the site. Abernethy Elementary School and Portland Environmental Middle School are located about 765 feet northeast of the site. The Oregon Museum of Science and Industry (OMSI) is located about 2,150 feet (0.4 mile) northwest of the site. As the site is securely fenced,it appears very unlikely that pedestrians, nearby residents, or potential trespassers would risk direct contact with the site s soil contaminants. At Portland, the Lower Willamette River is heavily used for recreational fishing, boating, and swimming. Any contaminants reaching the Willamette River could represent a potential threat to the river s recreational users. Downstream from the Willamette Falls, the Willamette River is important rearing and

PORTLAND GAS & COKE GAS HOLDER TANKS (FORMER) (Continued) S106980974 migration habitat for coho salmon, spring and fall Chinook salmon, and winter steelhead trout (see Figures 21a through 21c). Oregon Division of State Lands (DSL) has mapped the Lower Willamette River as Essential Salmonid Habitat (see Figure 21a). The river also provides important migratory habitat for summer steelhead, as well as habitat for searun cutthroat trout and the Pacific lamprey. Coho salmon is a state-listed Endangered Species. Chinook salmon and steelhead trout of the Lower Columbia River Estuary and Upper Willamette are federally-listed Threatened Species. Searun cutthroat trout and the Pacific lamprey are federal Species of Concern. Any contaminants reaching the Willamette River could represent a threat to the river s Threatened and Endangered fish species. A pair of bald eagles also nests on the western edge of Ross Island, 1-mile upstream from the outfall of the stormsewer that passes along the subject site s southern boundary. The bald eagle is a federally-listed Threatened Species. The stormsewer outfall lies within the bald eagles foraging range. Potentially-contaminated river sediment at the stormwater outfall could represent a threat to the bald eagles food supply.A 1909 Sanborn Fire Insurance map indicates that the former creek was directed to a stormsewer on the western edge of the site at that time (see Figure 14). An existing municipal stormsewer on the western edge of the site, constructed in 1963, is located 11- to 15-feet below SE 9th Avenue (see Figure 11). This western stormsewer may not be deep enough to capture stormwater from the depression on the southern end of the site: at its westernmost extent, the depression is about 15 feet below the level of SE 9th Avenue (see Figure 10). However, the western stormsewer could overlie an older sewer that once drained the creek. A municipal stormsewer, constructed in 1906, also lies along the site’s southern boundary, at least 34 feet beneath SE Taggard Street (see Figure 11). Potentially-contaminated groundwater and/or stormwater runoff from the southern third of the site could discharge to the stormsewer beneath SE Taggard Street, then discharge to the Willamette River, 0.25 mile west of the site. Subsurface contamination could represent a potential health threat to underground utility workers, or to utility trench workers. Contaminants could also discharge to the stormsewer, and contaminate Willamette River sediments. The former creek drainage might also provide a preferential migration pathway for contaminants to reach the river. A well boring log for the nearby Darigold, Inc. well, 550 feet west of the site (see Figure 18), indicates that local fill was placedover fluviolacustrine deposits comprised of loose and bouldery gravel. The subject site s southern depression and drywells could act as local groundwater recharge area to further enhance off-site migration of contaminated groundwater. The former creek drainage appears to parallel the southern edge of the Union Pacific Railroad mainline, and may pass beneath the Oregon Museum of Science and Industry (OMSI) building, near the eastern end of Interstate Highway 5 s Marquam Bridge (see Figure 1). Well logs from Oregon Water Resources Department (OWRD) indicate that the Irwin-Hodson Company, located immediately south of the site (see Figure 18), has a 153-foot deep industrial well that withdraws groundwater from a gravel formation (probably the Troutdale formation). The well log indicates that this well was deepened from its original depth of 113 feet bgs in 1967. Prior to 1967, the well appears to have withdrawn groundwater from a loose gravel formation (possibly fluviolacustrinedeposits). A geologist with Cascade Environmental Services, Inc. stated in January 2005 that the Irwin-Hodson well had been abandoned by filling the casing with a concrete-like material, however Oregon Water Resources Department (OWRD) still has no record of the well abandonment. Potentially-contaminated groundwater or phase-separated petroleum could also preferentially migrate to the river through the fluviolacustrine deposits, or possibly also along the nearby stormsewer s bedding.The site is the current location of the Northwest Natural Gas Company s (NNG s) Central Service Center, an active, securely-fenced, vehicle and utility service and maintenance yard

PORTLAND GAS & COKE GAS HOLDER TANKS (FORMER) (Continued) S106980974 owned by NNG (see Figures 1 through 4). The northern 2/3 of the 5-acre site is covered by several buildings (up to seven) and blacktop-paved parking areas (see Figure 3). A vehicle fuel dispensing area is located near the center of the site’s western property line. Three aboveground petroleum storage tanks (liquefied natural gas, waste oil, and a two-compartment tank containing diesel fuel and unleaded gasoline) are located near the center of the site (see Figure 9). Two large, aboveground, 155- to 175 foot diameter, circular concrete manufactured gas storage tank holder pads, and associated below-grade gas inlet vaults and gas transmission piping, are located in a 15- to 20-foot deep depression on the southern 1/3 of the site (see Figures 6 through 10). The larger, western pad (Pad #8) is the former location of a 3,000,000 cubic foot (22,500,000 gallons) aboveground storage tank; the smaller, eastern pad (Pad #7) is the former location of a 2,000,000 cubic foot (15,000,000 gallons) aboveground storage tank. The two circular concrete pads arenow used for vehicle parking. A third abandoned manufactured gas holder tank pad may be located further north, buried beneath fill and covered by a paved parking lot (see Figures 9 and 15). Storage capacity of the third tank was 2,000,000 cubic feet. At least five stormwater sumps surround the two exposed tank pads (see Figures 5a and 5b). DEQ and City of Portland records do not indicate if the sumps discharge to the municipal stormwater sewer system. The site’s former gas storagetanks appear to have been constructed in a low-lying area that was once traversed by an unnamed creek (prior to 1909); most of the creek’s former drainage appears to have been subsequently filled in, locally. By 1909, the creek s flow had been diverted to a sewer inlet at the site s western boundary (see Figure 14). At least four leaking petroleum underground storage tanks (gasoline, diesel fuel, and waste oil) have been removed from the site; at least four active aboveground petroleum storage tanks (ASTs) are currently located at the site (gasoline, diesel fuel, waste oil, liquified petroleum gas)(see Figure 9). Stormwater from the facility s blacktopped parking areas drains to any of 13 on-site catchbasins and associated drywells (see Figure 10).A Site Survey and Environmental Investigation, Former Northwest Natural Gas Company Manufactured Gas Holder Site, prepared for Northwest Natural Gas Company, by Hahn and Associates, Inc., July 22, 1991.

PORTLAND GAS & COKE GAS HOLDER TANKS (FORMER) (Continued) S106980974 Tank (HOT) File, Irwin Hodson Company, LUST #26-97-0130. City of Portland Corporate GIS system, http://www.portlandmaps.com . Oregon Water Resources Department well log and Water Right files, http://www.wrd.state.or.us . SanbornFire Insurance Maps, Oregon State Library.urface gas transmission piping that was attached to the tanks had been capped and decommissioned in place within the site boundaries when the tanks were decommissioned sometime in the late 1970 s or early 1980 s. Soil testing and soil and waste removals around the two southern tank pads were largely based on visual indications of staining. Soils remaining beneath and surrounding the site s two exposed southern concrete pads, as well as standing water and wastes within sumps, vaults, and piping associated with the pads, are either contaminated, or likely to be contaminated, with elevated concentrations of polynuclear aromatic hydrocarbons (PAHs), cyanide, and total and leachable lead. DEQ has no information to indicate that subsurface soils and groundwater at the site s two southern tank pads, or at the third (northern) tank pad, have ever been evaluated for hazardous substances. Minor concentrations of petroleum (diesel fuel and heavy oil or bunker fuel) also remainin subsurface soils and piping where gasoline, diesel fuel, and waste oil underground storage tanks (USTs) (see Figure 9) were decommissioned in 1993-95 (LUST #26-92-0217, #26-92-0344, and #26-95-0218). It remains unclear whether the subsurface soil contamination encountered in these areas was all associated with underground tank and piping leaks, or whether some may have been associated with material originally used to fill the site, or from historic manufactured gas storage activities. TCLP (toxic characteristic leachate procedure) leachable lead was detected at 5.5 ppm in soils excavated during a waste oil UST decommissioning in August 1995 (sample WO-6; 8/18/95). Excavated soils with greater than 5.0 ppm TCLP leachable lead qualify as a Toxicity Characteristic Hazardous Waste. Soils that were excavated at the waste oil UST site were sent to the Marion County Soil burner for remediation, although no further testing was conducted to determine the potential extent of leachablelead contamination remaining in subsurface soils at the former waste oil UST location. Relatively deep diesel fuel contamination was encountered during a 2004 heating oil tank decommissioning (LUST #26-97-0130) at the neighboring Irwin-Hodson Company facility, located on the subject site s southern boundary (see Figure 18). It is not known if the subsurface contamination is attributable solely to a heating oil tank release, or if some might be associated with the former manufactured gas holder tanks which are located about 45 feet north of the former heating oil tank; there is no record to indicate that potential off-site sources of contamination were adequately examined during the heating oil tank investigation. The heating oil tank was located just north of the Irwin-Hodson facility, in the SE Taggart Street right-of-way. Subsurface soils at the west end of the tank contained 12,000 parts per million (ppm) diesel fuel (with 13.8 ppm naphthalene) at 16.4 feet below ground surface (bgs), and 5,940 ppm diesel fuel at 20.8 feet bgs. No diesel fuel was detected in soils at the east end of the tank at 20.8 feet bgs, or at the same depths 6 feet west of the tank, or at 12 feet north of the tank, near the location of an east-west oriented municipal stormsewer line (see Figure 11). The municipal stormsewer line in this area is located about 34 feet below ground surface (bgs) (see Figure 11). The full extent of the subsurface contamination plume was not clearly defined; no deeper soil samples were collected. It is possible that historic subsurface soils excavations could have been conducted along the municipal stormsewer line, which would have removed or otherwise displaced potentially- contaminated soil sincethe sewer was constructed in 1906. Contaminated soils near the Irwin-Hodson heating oil tank were left in place because they contained only relatively low concentrations of VOCs and PAHs, and were concluded not to represent a significant threat togroundwater or to site workers. However, subsurface testing at the tank site was quite limited. There is no record to

PORTLAND GAS & COKE GAS HOLDER TANKS (FORMER) (Continued) S106980974 indicate that potential off-site sources of contamination were considered during the heating oil tank investigation. The highest detected concentration of diesel fuel (12,000 ppm) approaches the generic risk-based limit of 19,000 ppm for construction workers, while the highest detected concentration of naphthalene (13.8 ppm) approaches the generic risk-based limit of 18 ppm for utility trench workers. Any future sewer line work in this area could potentially result in unacceptable health risks to trench workers. The lower concentration of diesel fuel (5,940 ppm) is likely to have been detected very near the groundwatertable, which appears to be about 21 feet bgs (see Figure 17). Site Assessment is requesting that the DEQ Heating Oil Tank program re-examine the decision for no further action at the Irwin-Hodson tank removal.Petroleum and/or coal tar constituents (including PAHs, other semi-volatile organic compounds (SVOCs), and volatile organic compounds (VOCs)), lead, and cyanide. The majority of the contamination is present in soils, ponded water, and possibly groundwater, at two and possibly also a third - former manufactured gas aboveground storage (holder) tank pads, and associated below-grade sumps, vaults, and gas distribution piping. Minor residual subsurface petroleum contamination is also presentin areas where former underground petroleum storage tanks (USTs) and piping were decommissioned. Soil at the site s waste oil tank decommissioning location contained an elevated concentration of leachable lead. Soils beneath a 130 foot long gasoline/diesel fuel transfer pipe that was abandoned in place were contaminated with heavier oil or bunker fuel, which is inconsistent with the transfer line s use. It is unclear if all of the residual contamination (diesel fuel odors, as well as detectable gasoline, diesel fuel, and heavy oil or bunker fuel) was directly associated with UST and piping releases, or whether some could be associated with site fill, or historic manufactured gas storage activities. Debris encountered during the August 1995 removal of two of the sites USTs (LUST #26-95-0218), as well as soil boring lithologies from an investigation of subsurface transfer piping between the tanks and a former fuel dispensing island (borings B-1 through B-8; July 1995; available from OWRD) suggest that material imported to fill the site contained silt, gravel, wood, and construction debris. A very large variety of chemical products nearly 1,500 different products - are stored inside various site buildings, although quantities of the vast majority of chemicals may be relatively small. The chemical products include paints, cleaning compounds, solvents, lubricants, petroleum products, coolants, other vehicle maintenance products, polymerizers, compressed gasses, welding supplies, bulk chemicals, adhesives, water treatment chemicals, shot blast, inks, sealants, herbicides, insecticides, refrigerants, other chemicals, and lead-acid storage batteries.(1/5/94 GMW/SAS) Options letter sent; no further remedial action anticipated by RP. Further evaluation recommended. (9/8/06 SMF/SAS) Site priority for further investigation and cleanup was revised to high.Manufactured gas was at one time stored in three on-site aboveground gas holder tanks (see Figure 4) which rested on circular concrete pads; at least two of the site s concrete tank pads still exist (see Figure 3). A third pad may be located beneath an on-site paved parking lot (see Figures 9 and 15). The three gas storage tanks had capacities of 2-million-, 2-million-, and 3-million cubic feet (see Figure 12), and were present from at least the 1920 s through the 1980 s, although the actualtime span for gas storage use is not known at this time. Soils in the vicinity of manufactured gas holding tanks are often heavily contaminated with polynuclear aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), toxic metals, and cyanide that commonly condense from the stored gas. Prior investigations at the site s two southern tank locations (from March 1991 through May 1992) encountered elevated concentrations of leachable lead, leachable cyanide, benzo(a)pyrene, benzo(b)fluoranthene, and indeno(1,2,3-c,d)pyrene in black- and bluish-colored

PORTLAND GAS & COKE GAS HOLDER TANKS (FORMER) (Continued) S106980974 waste piles and soils, and in standing water (see Figures 5 through 8). Phase-separated petroleum containing greater than 90 percent C10-C28 hydrocarbons (a mixture of gasoline, diesel fuel, and heavy oil or bunker fuel) was also encountered on standing water at the site, although investigational reports do not specify where the sample was collected. A background soil sample collected at the southwest corner of the site contained an elevated concentration of lead. Water at stormwater sumps adjacent to the tank pads was contaminated with elevated concentrations of total cyanide and leachable lead. Northwest Natural Gas (NNG) excavated the wastes piles and much of the contaminated surface soils, and removed accessible wastes from some of the abandoned piping associated with the site s two southern tank pads in 1991-92. Cleanup confirmation samples collected in 1991-92 indicate that surface soils have largely been cleaned up, although contaminated soils remain in inaccessible areas, and contaminated water and wastes remain in subsurface piping, tank inlet vaults, and in stormwater sumps associated with the pads (see Figures 5a and 5b). A single follow-upsoil sample collected at 3 feet below ground surface (bgs) along the southeastern perimeter of the site s eastern tank pad (Pad #7) on September 14, 1993 contained no detectable petroleum hydrocarbons when analyzed by Oregon DEQ Method TPH-418.1. Each of the two southern tank pads has three gas inlet vaults that were constructed as integral parts of the concrete tank pads (see Figure 5b). In 1992, each of the six vaults was estimated to contained between 6,450- and 7,250-gallons of cyanide- contaminated water (41,100-gallons, total). Testing of the vaults indicated that the water was contaminated with cyanide. Wastes in open piping within the vaults contained even higher concentrations of cyanide and petroleum hydrocarbons. No estimate was provided for the volume of water remaining within the underground piping, although, at their inlets, the pipes appear to have been up to 5-feet in diameter. The City of Portland permitted NNG to discharge approximately 19,000 gallons of contaminated water from the eastern pad s gas inlet vaults (Pad #7) to the municipal sanitary sewer in August 1993. However, because of the higher concentrations of cyanide at the western pad (Pad #8), the city would not allow water from Pad #8 to be discharged without pre-treatment. There is no record to indicate that the contaminated water in the western pad s gas inlet vaults (Pad #8), or any of the stormwater sumps, was ever removed or treated. The volume of contaminated water at the western pad vaults was subsequently revised downward (to 6,500 gallons) in September 1993. It is unclear from the consultant s report whether the revised 6,500 gallon volume estimate represented an estimated volume of water in each gas inlet vault at Pad #8, or an estimate of total water in all three Pad #8 vaults. If the revised estimate represented the total volume of water in all three Pad #8 vaults, this implies that the vaults may have leaked: Total water volume in the Pad #7 vaultsdid not change during the same time period. At that time, vaults and associated inlet pipes at the western pad were backfilled with absorbent soil and crushed rock, in preparation for paving over the tank pads. There is no record to indicate that the contaminated water in the western pad s gas inlet vaults (Pad #8), or any of the stormwater sumps, was ever removed or treated. DEQ has no information to indicate whether, or not, water within the vaults and associated subsurface piping, or in the stormwater sumps surrounding the concrete holder pads, is in direct hydraulic connection with the site s shallow groundwater. It is not known if the stormwater sumps are connected to the municipal stormwater sewer system.

Envirocomp Services conducted a Phase II investigation in October 2002. Based on DEQ s comments on the ICP Report, which contained results from the previous Phase I and Limited Phase II investigations, ECS conducted additional site characterization sampling in May 2003 to better define the extent of contamination. At DEQ s request, ECS requested further lead analysis on soil samples that had been retained by the analytical laboratory.(9/15/03 MTP) Earth Tech Inc. (Earth Tech) conducted a Phase I Environmental Investigation and documented the results in a draft report dated August 17, 2001. During the investigation Earth Tech advanced 3 soil borings. Chemical analysis detected total residual range organics (RRO; similar to total petroleum hydrocarbon (TPH) as heavy oil) at a concentration of 2,900 milligrams per kilogram (mg/kg) from a sample collected from 1 to 2 feet below ground surface (bgs) in boring B-2, advanced nearan oil storage area. Residual diesel-range organics (DRO; similar to TPH as diesel) was detected at a concentration of 220 mg/kg in this sample. The sample from 5 feet bgs at this location contained RRO at 1,000 mg/kg, but did not contain detectable DRO. DRO and RRO were not detected in the other two borings. Earth Tech concluded that the TPH contamination represented approximately 10 to 15 cubic yards of soil, and was the only environmental concern at the site. Northwest Envirosearch conducted a Phase I investigation in 2002. They observed excess petroleum oils in the outside storm water catch basin, which is connected to the City of Portland sanitary sewer. Northwest Envirosearch recommended the catch basin be cleaned, but it is not clear if this occurred. DEQ did not observe petroleum in the catch basin during a site visit on April 22, 2003. Northwest Envirosearch concluded that the petroleum in the catch basin was the only environmental concern at the site. As indicated in a later report, Northwest Envirosearch was unaware that a previous Phase I investigation had been conducted, and that elevated TPH concentrations had been detected in soil. Phase II Investigation (ECS, 2003) ECS conducted A Phase II investigation in October 2002 to evaluate the extent of contamination detected in the earlier investigation. A total of six borings were advanced to total depths ranging from 8 to 12 feet bgs (ECS B-1 through ECS B-6). In borings ECS B-3 and ECS B-4, ahorizon of soil from approximately 3- to 4.5 feet bgs brick fragments and charred wood was observed that appeared to be residue from a fire. The borings did not encounter groundwater at the maximum depth of 12 feet bgs. ECS submitted one sample from each boring for hydrocarbon identification analyses (HCID). Based on the HCID results, the sample collected from 4 feet bgs from ECS-B3 was further analyzed for extended range diesel (TPH-Dx). The analysis indicated TPH as heavy oil at a concentration of 180 mg/kg, and TPH as diesel (TPH-D) at a concentration of 60 mg/kg. TPH was not detected in sample ECS B-1, collected with about 1 foot of Earth Tech s boring B-2, where an elevated petroleum hydrocarbon concentration had been detected. Both samples from ECS-B-1 (2 and 4 feet) were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX), in addition to polynuclear aromatic hydrocarbons (PAHs). BTEX were not detected, but a number of PAHs were detected. With the exception of benzo(a)pyrene (0.0713 mg/kg) in ECS B-4, all PAH concentrations were below DEQ s risk-based concentration (RBC) for direct contact with soil under a residential-use scenario. All concentrations were below the RBC for direct contactunder an occupational-use scenario. Based on DEQ s comments to the ICP Report, which contained results from the previous Phase I and Limited Phase II investigations, ECS conducted additional site characterization sampling in May 2003 to better define the extent of contamination. A total of seven borings were advanced to a total depth of 8 feet bgs (ECS B-7 through ECS B-13). Groundwater was not encountered in any of the borings. Borings ECS B-9 and ECS B-13 exhibited evidence of a fire (i.e., charred debris and black staining) at

GRANT STREET PROPERTY (Continued) S105807711 a depth of 3.5 feet, similar to previous observations ECS B-3 and ECS B-4. One sample from each boring was submitted for HCID analyses. Petroleum hydrocarbons were detected in the stained interval (3 feet bgs) in ECS B-9, and follow up TPH-Dx analysis indicated the sample contained 245 mg/kg TPH as heavy oil. TPH was not detected in a sample collected from 4 feet bgs from ECS B-9, immediately below the stained interval. The 3-foot sample was further analyzed for BTEX, in addition to PAHs. BTEX were not detected; a number of PAHs were detected. All PAH concentrations were below their respective RBCs for direct contact with soil under an occupational-use scenario. To evaluate the presence of waste oil constituents, the sample from ECS B-9 also was analyzed for cadmium, chromium and lead, and polychlorinated biphenyls (PCBs). These additional analyses are consistent with DEQ guidance for evaluation of waste oil contamination. PCBswere not found above method detection limit of 67 micrograms per kilogram (ug/kg). Reported cadmium (1.5 mg/kg) and chromium (28.6 mg/kg) concentrations appear to be within the range of naturally occurring concentrations, and are well below their respective U. S. Environmental Protection Agency Region 9 Preliminary Remediation Goals (PRGs) for industrial use soil. The lead concentration of 3,390 mg/kg in ECS B-9 is over three times its RBC of 1,000 mg/kg for industrial use soil. A Toxicity Characteristic Leaching Procedure (TCLP) analysis also was conducted, with a lead result of 0.41 milligrams per liter (mg/L). Cadmium and chromium were not detected in the TCLP leachate. At DEQ s request, ECS requested further lead analysis on soilsamples that had been retained by the analytical laboratory. Additional lead analysis was conducted on four samples. Three of the samples collected from borings in the vicinity of ECS B-9 (i.e., ECS B-10, ECS B-11, ECS B-12) were within the rangeof expected naturally occurring lead concentrations ( 17 mg/kg), and appear to define the extent of lead impacted soil in this area. The lead concentration reported for ECS B-7 was 66.8 mg/kg, and although elevated with expect to the expected background level of 17 mg/kg, is well below the RBC for direct contact with industrial soil (1,000 mg/kg).Phase I Investigation (Northwest Envirosearch, 2002); Supplemental Phase II Investigation (ECS, 2003).

Adjacent site in the Voluntary Cleanup Program (South Waterfront, Lot 5). NFA for Lot 5 is currently under a 30-day public notice and comment process. Lot 3 will be used for construction staging by developers of Residence Inn by Marriott on Lot 5. Requested ICP to determine if additional soil/groundwater sampling and analysis is needed for NFA status. (6/12/01 TER/VCP) Based on the need for a complete remedial investigation, the project was transferred from ICP to VCP. PDC is conducting additional soil and groundwater sampling to complete the site characterization. (11/5/02 TER/VCP) A Remedial Investigation Report with Risk Assessment was submitted to DEQ inOctober 2002. Petroleum hydrocarbon contamination presents an unacceptable risk only if site work or redevelopment is conducted below 10 feet. DEQ is preparing a Staff Report, recommending an easement as an institutional control to ensure future development and site use address the identified exposure risks. (4/5/04 TER/VCP) DEQ signed the Record of Decision 1/28/04. An easement has been drafted for review by the Portland Development Commission.Potential human exposure to contaminants through inhalation, ingestion or direct contact with contaminated soil.Past operations of the Portland Lumber Company and adjacent Schnitzer may have resulted in petroleum releases. Undocumented fill material may contain contamination.Diesel and heavy oil-range petroleum hydrocarbons; carcinogenic and non-carcinogenic PAHs; metals, primarily lead.The site is currently vacant. Future development could result in construction worker exposure to contaminants in soil. The Willamette River is approximately .25 mile east of the site, but contaminants in groundwater do not appear to be migrating off-site.Soil and groundwater.South Waterfront Lot # 3 is adjacent to the RiverPlace development located at SW. Harbor Drive and River Parkway, in downtown Portland. In the early 1900s the Portland Lumber Company occupied part of Lot #3. The area has since been built up over time with undocumented fill including soil, wood waste, and other refuse. The site is currently vacant, but is slated for development. The Portland Development Commission (PDC) joined the Voluntary cleanup Program in December 1999, and conductedsoil and groundwater site investigation activities. A remedial investigation and

SOUTH WATERFRONT REDEVELOPMENT AREA 3 (Continued) 1006851219 risk assessment was completed by the PDC in October 2002 to evaluate concentrations of contaminants in soil and groundwater at the property. The main contaminants ofconcern are petroleum hydrocarbons, polynuclear aromatic hydrocarbons, and lead, and the highest concentrations detected are in a black-stained layer of soil 14 to 25 feet beneath the site. The risk assessment indicates that contaminants are belowconcentrations that pose a significant risk to human health unless contaminated soil below 10 feet is excavated during future site development. Shallow groundwater beneath the site is not used and contaminants in groundwater have not migrated significantly off-site. To address soil and groundwater concerns DEQ completed a Record of Decision January 2004 recommending an easement on the property that requires engineering and worker health and safety protections during site development, andoffsite disposal at a permitted facility of any contaminated soil excavated below 10 feet. Groundwater use will be restricted through the easement. STATUS DEQ and Portland Development Commission are preparing the Easement and Equitable Servitude for the site remedy.

PCB oils were generally used in electrical equipment from the mid-1930s to the 1970s. Soils, various structures on-site, and Willamette River sedimentsare known to be contaminated with PCBs. This contamination was likely to have occurred from releases of oil from transformers.PCBs, heavy metals, BTEX, PAHsSite of new OMSI facility, plus 10 acres to south.Releases from electrical equipment containing PCB oils, likely between mid-1930s to 1970s.Remediation of river sediments completed.Inman - Poulsen Lumber Co., OWP, PRI, closed 1954ROD for No Further Action issued 9/26/94. Phase II: Sediment cap inspection and monitoring to be conducted every 5 years for next 25 years.There is soil & river sediment contaminated with PCBs.(1/17/1996 JAK/SRS) River sediment remediation, including dredging and capping, was conducted from July 1990 to January 1991. Maximum residual concentration of PCBs in sediment is approximately 21 ppm, with an average concentration of 8 ppm. The multi-layer cap was constructed with sand, gravel, and riprap to a thickness of greater than 6 feet. DEQ issued a Certificate of Completion for the sediment cleanup in April 1991. Monitoring of the sediment cap ongoing through 2020. Upland investigation (Phase III) for hazardous substance releases anywhere on the 28-acre site completed.

City had to replace corroded sewer pipe 3/80. A 40-foot length of 8-inch concrete pipe had been completely eaten out along its bottom. This plant is the largest source of plating wastes in the city (3/79). City initiated enforcement action to reduce facility’s discharge. Site was in apparent compliance with RCRA conditions in 1984. See Strategy Recommendation in site files for more information. Beginning in 1987, TCE was found in monitoring wells downgradient of site; these wells were installed as part of PGE Station L investigation (ECSI #151). It is possible that the TCE originated from East Side Plating.DEQ CERCLIS file;

EAST SIDE PLATING - PLANT 4 (Continued) S103842042 Inspection reports; EPA CERCLA Preliminary Assessment; Site Investigation; Lab results; City of Portland Sewer Discharge Info; Air Permit info; Preliminary Assessment by Hahn & Associates, 6/29/95.Cadmium, chromium, cyanide, hydrochloric acid, zinc, nickel, copperSoil (around damaged sewer pipes), as well as possibly groundwater beneath facility. Groundwater may occur at a depth in excess of 50 feet beneath site.In response to DEQ review, RP conducted own PA with Hahn & Associates. Hahn completed the PA in June 1995, and it concluded that releases from corroded sewer piping prior to 1981 could have caused subsurface contamination. Hahn installed four soil borings beneath the replaced sewer pipe 11/95, which showed little or no metals or VOC contamination at this location. Based on this data, Site Assessment has downgraded the further-action priority to LOW. There is still no information on the fate ofheavy metals that were released through the break in the city sewer line, nor does the Hahn PA address other possible release areas for metals or VOCs from the site to soil/groundwater.There is a good chance that the ESP facility has released metals and solvents to soil/groundwater. If this is the case, subsurface contamination could affect downgradient industrial supply wells, water in the on-site well, and surface water in the Willamette River.

REXEL/TAYLOR ELECTRICAL SUPPLY (Continued) S108010613 responsible for entering the Voluntary Cleanup Program (VCP) as requested by DEQ. Rexel Inc., the tenantat the time of the fire, offered to enter the VCP to address our concerns but indicated that they do not have the authority to access the property. This has been rebutted by Mr. Taylor. Since the current circumstances do not indicate the VCP process is viable, we are referring the site to the DEQ Site Assessment Program for further evaluation. A timeline for this evaluation is uncertain. DEQ requested Rexel Inc. to provide complete information on the materials and equipment that were stored in the warehouse at the time of fire. DEQ has requested that Mr. Taylor provide information on the disposition of fire debris and any other material disposed off-site, and any subsequent environmental investigation or cleanup conducted at the site.A warehouse fire erupted at this site on the morning of 5/17/06.Fire suppression water entered the City storm drain system and resulted in a sheen on the Willamette River but no free product warranting recovery efforts was present. Likely elevated metals and possible PAHs in fire debris. PGE submitted a reportthat indicated PCB-containing transformers were consumed in the fire. however, no environmental media have been sampled.Industrial area in SE Portland.Releases to storm drain that eventually drains to Willamette River (1000 feet from site). The building covers virtually the entire property, so exposure to contaminated soil may not be a complete pathway. fire debris likely contains hazardous substances and should be appropriately disposed off-site.PGE removed their burnt transformers. Rexel hired Elder Demolition and reportedly salvageable metal has been removed from the fire debris. The status of fire debris removal is unknown.Transformer Oil Release Report, OERS No. 06-1238, PGE, June 8, 2006.The Rexel/Taylor Warehouse is located in SE Portland at the corner of Clay and 3rd Street. The fire started around 10:30 PM on May 17th and involved materials stored in the warehouse (mainly wiring), but reportedly some transformers. Three transformers owned by PGE were incinerated, with an estimated release of less than 10 gallons of oil. The balance of 110 gallons is presumed to have been consumed in the fire.Threat to human health may exist from fire debris. Once the fire debris is removed the risk from residual contamination will likely be low, as the soil at the site is almost completely covered with concrete. The storm drain lines and associated contaminants could present an ongoing source of residual contamination to the Willamette River, but due to the expected limited volume is not expected to present a signifcant threat to humans or wildlife.Warehouse that caught fire with considerable coated wiring and other material consumed. Environmental concerns include impacts to storm drain system, potential residual contamination in site soil. PCB containing transformers were consumed in the fire. Oil from forklifts may have been released.

OR-DEQ (Oregon - Department Of Environmental Quality) is a regulatory agency whose job is to protect the quality of Oregon’s Environment. DEQ uses a combination of technical assistance, inspections and permitting to help public and private facilities and citizens understand and comply with state and federal environmental regulations.

AFS (Aerometric Information Retrieval System (AIRS) Facility Subsystem) replaces the former Compliance Data System (CDS), the National Emission Data System (NEDS), and the Storage and Retrieval of Aerometric Data (SAROAD). AIRS is the national repository for information concerning airborne pollution in the United States. AFS is used to track emissions and compliance data from industrial plants. AFS data are utilized by states to prepare State Implementation Plans to comply with regulatory programs and by EPA as an input for the estimation of total national emissions. AFS is undergoing a major redesign to support facility operating permits required under Title V of the Clean Air Act.

NCDB (National Compliance Data Base) supports implementation of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Toxic Substances Control Act (TSCA). The system tracks inspections in regions and states with cooperative agreements, enforcement actions, and settlements.

The NEI (National Emissions Inventory) database contains information on stationary and mobile sources that emit criteria air pollutants and their precursors, as well as hazardous air pollutants (HAPs).

RCRAInfo is a national information system that supports the Resource Conservation and Recovery Act (RCRA) program through the tracking of events and activities related to facilities that generate, transport, and treat, store, or dispose of hazardous waste. RCRAInfo allows RCRA program staff to track the notification, permit, compliance, and corrective action activities required under RCRA.

OREGON HEALTH SCIENCES UNIVERS (Continued) 1000431703 ICIS (Integrated Compliance Information System) is the Integrated Compliance Information System and provides a database that, when complete, will contain integrated Enforcement and Compliance information across most of EPA’s programs. The vision for ICIS is to replace EPA’s independent databases that contain Enforcement data with a single repository for that information. Currently, ICIS contains all Federal Administrative and Judicial enforcement actions. This information is maintained in ICIS by EPA in the Regional offices and its Headquarters. A future release of ICIS will replace the Permit Compliance System (PCS) which supports the NPDES and will integrate that information with Federal actions already in the system. ICIS also has the capability to track other activities occurring in the Region that support Compliance and Enforcement programs. These include; Incident Tracking, Compliance Assistance, and Compliance Monitoring.

Also, 0.5 ppm PCE at approximately 13 feet bgs in same boring.[12/15/2004, RH] The contaminants from the UST systems are present and cleanup via soil removal has occurred. Confirmation soil sampling and expanded subsurface investigation has been completed. Cleanup appears complete at the gasoline UST area, although one of the confirmation samples which previously detected gasoline did not detected benzene with a 5.0 ppm detection limit. Further soil sampling did not detect gasoline in a pit sample. In the vicinity of the former bunker C oil tank, highconcentrations of deisel and oil remain in the pit area (this is where the PCE was detected). The expanded soil investigation did not detect diesel or oil to 15 feet bgs, which may not be cemented gravel and sand was reported and there was geoproberefusal. No further investigation has been completed.DEQ reviewed a report from David Brown & Associates that may be missing from the site files.

Krishell Laboratories also repackaged concentrates. Former manager left the firm in 1951 and indicated there was no direct manufacturing of any pesticides nor was there any wastes generated by the facility. 30- and 55-gallon drums were re-used to package their products. The firm supposedly closed around 1963.EPA visited the facility in 1980. Found a newer building at location, which was occupied by a wholesale food-products firm. EPA Assessment Priority: None. Reason: There is no record of hazardous substances existing on-site, and therefore, it is recommended that this site be closed. EPA forwarded information to DEQ.

It is unknown how many transformers contained oil with PCBs, or how (or if) that oil was disposed of. A manifest from 11/84 shows transformers with up to 26 ppm PCBs beingshipped to the site. A 9/87 PA that DEQ performed for EPA recommended a medium-priority SI to sample for PCBs and related combustion compounds (dioxins and furans). Soon after the PA was completed, however, the site passed a TSCA inspection, and EPAdecided that no further action under the federal Superfund program was necessary. An 8/96 DEQ site visit revealed that Winkler has not operated at the site for about 7 years, and used several neighboring buildings in addition to the 1737 Rhine address. All of these buildings were occupied by businesses, and there was no evidence of contamination on the 1737 property, nor around the other buildings.DEQ CERCLIS file; EPA CERCLA Preliminary Assessment (9/87); lab results for oil in transformers shipped to site in 1984; 8/96 site visit.Potential contaminants include PCBs, solvents, phenols, 1,2-dichlorobenzene, bis(2-ethylhexyl)phthalate, dioxins & furans.Winkler also operated out of an adjacent bldg. at 1705 SE Rhine, and a bldg. across 17th Ave. (3401-3435 SE 17th). Winkler Scrap Metal now operates at 5611 NE Columbia Blvd.There is no documentation that any releases of PCBs or other hazardous materials occurred at the site.(GMW 8/20/96) DEQ added this site to ECSI and conducted a PA due to historically poor waste-management practices among electrical equipment metal salvage operators. There is no evidence that PCB releases occurred, and EPA’s 8/87 TSCA inspection didnot result in any citations. In addition, DEQ found no evidence of contamination during an 8/96 site visit. However, based on DEQ’s experience with other metal salvagers, it is possible that PCBs and related compounds were released, and remain in the environment. DEQ needs further information on historical operating practices, and perhaps samples from selected areas, to reach a final conclusion about the site. Further state action to research past operating practices is a low priority. OR ECSI ECWQ: Owner Site Num: 132285 FACA ID: 5841 Site Name: Winkler Scrap Metal Inc.

The U.S. EPA requested that DEQ evaluate these three sites (ECSI #3066, 3067, and 3090), and determinewhether past industrial operations might have left behind lead contamination that poses threats to human health or the environment. (2/8/02 CB/SAS) Any potential site contamination that may have been imparted by the Multnomah Metals Co. has longsince been removed, redistributed, and/or covered as a result of the area s redevelopment. At this time, there are no overt indications of contaminants related to the manufacture of lead-containing metals being present at, or migrating from, this location.(2/8/02 CB/SAS) Given the information provided for this assessment, DEQ is recommending no further action regarding the investigation of possible lead contamination at this location. DEQ may reinitiate this investigation of this site should information become available in the future suggesting that contaminants of concern are indeed present.This site is situated on what is now the south end of Waterfront Park, on the west bank of the Willamette River, and at the foot of SW Clay St., near downtown Portland. The northbound lanes of SW Naito Parkway presently occupy what was the western face of the Multnomah Metals Co. building. The entire property is now owned and maintained by the City of Portland. The property in question was originally two parcels, each having its own address: 312 and 314 Front Ave. In the mid-1930s, the city s address format was changed, and the address numbers of 1434 and 1438 were assigned to this property. While two buildings were present, one at each address, they appear to have been internally connected and jointly operated according to Sanborn Fire Insurance Company maps from as early as 1909.The earliest mention of the Multnomah Metals Co. at this location is from the 1912 Polk City Directory, which lists the company as a Manufacturer of Babbitt Metal and Solders 156 Flower, Office 312 Front. The continued occupancy of the 312 FrontStreet address by the Multnomah Metals Co., is indicated from 1915 until 1960. These listings include a variety of subject headings occurring over the years such as: rags importers, rag dlrs, junk, waste dlrs, and mfrs agts. None of these headings necessarily suggests that metal-working activity occurred at that location, but rather that materials salvage of various sorts took place there. The only notable exceptions to these headings are a Portland Fire Bureau inspection log listing the site as an industrial laundry from 1949 1952, and a 1968 site demolition report where the Portland Bureau of Buildings describes the site as a whse. & store & factory. These listings, in addition to the lack of any metal smelting apparatus or chimneys depicted on the Sanborn maps, suggest that this location was not used for metals manufacturing. To the contrary, it appears that the Front Ave. location may have served as both an office and a type of junk and/or scrap metal depot or

CITY OF PORTLAND SW FRONT AVE PROPERTY (Continued) 1006852612 storage facility, while the company s 156 Flower address was the actual location of the smelting facility. This presumption is corroborated when examining the 156 Flower St. location on Sanborn maps for the early to mid 1900s. The discovery ofthis second location has led DEQ to evaluate the Flower St. portion of Multnomah Metals Co. -- ECSI #3274. After the building was razed in 1968, the property appears to have remained vacant, and was relatively isolated by Water Ave. to the west,and by the Harbor Drive Freeway to the east. In a period lasting from roughly 1977 to the early 1990s, Water Ave. and the Harbor Drive Freeway were removed, and the property in question was gradually transformed, along with the surrounding lands, into what is now the McCall Waterfront Park Amphitheater.

EPA apparently got the original address (1700 SW 4th) through a targeted search. When the "correct" address turned out to be 1500 SW 1st, EPA shifted the focusof the PA to the new address. However, both locations were merely office buildings in downtown Portland. No hazardous substances had ever been used, stored, or disposed of at either site. EPA quickly determined that no further action was necessary under the federal Superfund.1) CERCLA Preliminary Assessment. 2) Correspondence FROM owner/operator.none(8/31/93 KPD/SAS) There is no indication that reportable quantities of hazardous substances have ever been used, stored, or disposed of on-site.

EPA requested that DEQ assess three different properties in the City of Portland due to concerns regarding their historic use of heavy metals (mainly lead). The Multnomah Metals Company operated one of these three sites at 1434 SW Front Ave. in Portland (ECSI #3090). In the process of evaluating historic documents and records for the Front Ave. site, repeated references were made to a Multnomah Metals Company "Works" facility at 156 SW Flower St. in Portland. Inquiries into the Flower St. property revealed the presence of "melting pots" at that location. Records indicate that this site served as an operations facility for the MultnomahMetals Company for roughly 65 years, from 1910 to sometime in 1975. According to Sanborn Fire Insurance Company maps, the facility was used for the smelting of metals as early as 1924, to as recently as 1965. In the 1970s, the property transitionedtowards residential use, yet seems to have maintained at least some type of small business classification since that time. The parcel in question was re-zoned for residential dwelling construction in 1974, and the original industrial structures on these premises were demolished the following year, in 1975 . In 1976, a new single-family residential dwelling was erected on this site, and residential use has persisted to the present. (2/24/03 CJB/SAS) DEQ sampling of surface soils was performed on 2/10/03, at four locations along the eastern and northeastern property boundaries. Concentrations of lead were between 617 and 5,120 mg/kg. The U.S. EPA Region 9 Preliminary Remediation Goal (PRG) for lead in residential soils is 400 mg/kg.Lead.According to the Polk City Directory, the mailing address for the Flower St. parcel was changed to 0236 sometime between 1930 and 1935 as part of postal service expansion in the area.Based on the presumption that metals contamination is the primary concern for hazardous materials exposure at this location, the pathways of greatest concern are direct contact, inhalation, and surface water. There do not appear to be significant direct-contact exposure pathways for current occupants, unless subsurface excavation occurs at the site. Disturbing the soils and/or building foundation may create an opportunity for both direct contact and inhalation exposures. The historic presenceof an apparent metal-working operation at this site may have contributed to subsurface contamination in the area. Potential subsurface contaminants could create an exposure risk to trench/utility workers. Any threat that may be posed to vegetation and/or wildlife by these conditions does not appear to be significant, and there were no obvious signs of stress to local biota observed. There are no open surface water bodies in the immediate vicinity ( 350m) of the site; however there is a possibility that either sanitary or storm sewers have carried site-related contaminants to the Willamette River. The City of Portland’s complete reconstruction of local sewers in this neighborhood is currently ongoing. This construction may raise the issueof trench-worker exposure; however none of this work is occurring at or immediately adjacent to the site. Without evidence that a potentially hazardous release occurred at this site, DEQ believes the surface water pathway is of minimal concern.DEQ surface soils data lead analysis (2/19/03).Lead found in soils analysis dated 2/19/03. Concentrations: 617, 2360, 4400, and 5120 mg/kg.(5/31/02 CJB/SAS) The investigation of potential site concerns necessitates the sampling of various media associated with this property. Sampling for metals would allow specific identification and quantification of contaminants of potential concern.Furthermore, a sampling plan designed to address areas least likely to have been disturbed over time,

MULTNOMAH METAL CO., WORKS (FORMER) (Continued) S106082727 as well as those most prone to cause maximum exposure to residents, would provide the information needed to better assess the risks that may be posed at this location. A sampling plan should be targeted to the following locations at a minimum: 1) surface and subsurface soils representative of the property, especially beneath the foundation crawl-space if the home design is applicable; and 2) dust wipe samples of the home’s interior, especially in the basement if the home’s design is applicable. DEQ also recommends that a sampling plan be developed, and upon DEQ approval of the plan, that sampling proceed with DEQ oversight.The environmental persistence and toxicity of metals contaminants raises concern for the possibility of exposure to potentially hazardous materials that may have been left behind following the removal of the Multnomah Metals Company factory structures on or about 1975. The presence of a residential dwelling at this location creates an opportunity for recurrent exposure to these contaminants by its occupants. Modifications to the home or yard could worsen this exposure potential.(4/24/03 CJB/SAS) Letter received from property owner (Boni Halton) on 4/18/03. States she has sought counsel regarding her options to address the site through ICP, VCP, on her own, or wait for SRS, yet no conclusion has been reached. Letter has been added to ECSI file. Telephone call to Ms. Halton at (503) 635-5294 (Halton Development). Left message indicating receipt of above letter. Requested notification of her decision as to how she would proceed, and informed her that the site will bereferred to SRS.The exact manner of release is unknown. Lead contamination is suspected of having been released durring historic metal working operations. Additional lead may have been deposited in local soils from deteriorating leaded paint and accumulated auto exhaust. Lead may also have been present in apparent fill material brought to the site following the demolition of the Multnomah Metal Co. facility. Levels of lead identified suggest that the source was substantially concentrated, and/or present for along period of time (perhaps several decades).

In 1986, OECO moved to a site in Milwaukie, which has a separate ECSI file (#1119). OECO uses solvents to clean and degrease electrical parts. A copy of a 1991 e-mail found in OECO’s Milwaukie site file suggested that solvent releases from a UST had occurred at this Portland site. Site Assessment obtained the 1990 UST removal report from OECO 5/96; it documented low levels of VOCs in soil beneath the decommissioned 1,000-gallon waste solvent tank (which had not been used since 1983). The tank and associated piping were in poor condition, suggesting leakage while the tank was in operation. After the hole was backfilled in 1990, a soil boring was installed to 3 feet below the fill end of the UST, reportedly encountering no VOC contamination. In 10/91, DEQ’s RCRA program wrote a letter to OECO’s attorney indicating that DEQ considered the tank to have been a hazardous waste generator accumulation unit, rather than a RCRA-regulated storage unit subject to permit. This letter also indicated DEQ’s opinion that the tank had been closed adequately, according to RCRA regulations.EPA Preliminary Assessment forms; 1990 UST removal report completed by SRH Group; correspondence, notes, and memos created by OECO and DEQ (contained in ECSI file #1667).Chlorinated and petroleum-based solvents; possibly metals. OECO generated approximately 7,000 gal. of waste solvent in calendar 1985, its last year at this location.OECO’s occupancy also included 732 SE Hawthorne Blvd., 1530 SE 7th Ave., and possibly other nearby/adjacent buildings.Possible release of waste solvents from an underground storage tank. Time of release: unknown.The site is located in Portland’s Central Eastside Industrial District, where there are not likely to be any drinking water wells in use. Groundwater is expected to occur at a depth of between 15 and 25 feet at the site.(7/5/96 GMW) Some documentation is missing from the site’s DEQ files, and OECO could provide only a portion of relevant site documents following a 4/96 request for information. It appears that no further soil removal or other site investigation occurred

OECO CORP. - PORTLAND (Continued) S103842609 after 11/90. Although a soil boring beneath the part of the UST that was contaminated came up non-detect for solvents, further investigation is needed to confirm that no soil contamination remains at the site. Groundwater in the vicinity of theformer tank should also be sampled. Site Assessment believes these actions are necessary, because: 1) the age and condition of the UST at removal suggest that significant quantities of solvent were released; and 2) the water table is expected to berelatively shallow in this area, so that any releases, especially of chlorinated solvent, would likely have migrated to groundwater. Further state action at the site is a low-to-medium priority. OR ECSI ECWQ: Owner Site Num: 132999 FACA ID: 2886 Site Name: OECO Corp. - Portland Owner Name: OECO Corp.

Code Description ______

D001 IGNITABLE HAZARDOUS WASTES ARE THOSE WASTES WHICH HAVE A FLASHPOINT OF LESS THAN 140 DEGREES FAHRENHEIT AS DETERMINED BY A PENSKY-MARTENS CLOSED CUP FLASH POINT TESTER. ANOTHER METHOD OF DETERMINING THE FLASH POINT OF A WASTE IS TO REVIEW THE MATERIAL SAFETY DATA SHEET, WHICH CAN BE OBTAINED FROM THE MANUFACTURER OR DISTRIBUTOR OF THE MATERIAL. LACQUER THINNER IS AN EXAMPLE OF A COMMONLY USED SOLVENT WHICH WOULD BE CONSIDERED AS IGNITABLE HAZARDOUS WASTE.

D002 A WASTE WHICH HAS A PH OF LESS THAN 2 OR GREATER THAN 12.5 IS CONSIDERED TO BE A CORROSIVE HAZARDOUS WASTE. SODIUM HYDROXIDE, A CAUSTIC SOLUTION WITH A HIGH PH, IS OFTEN USED BY INDUSTRIES TO CLEAN OR DEGREASE PARTS. HYDROCHLORIC ACID, A SOLUTION WITH A LOW PH, IS USED BY MANY INDUSTRIES TO CLEAN METAL PARTS PRIOR TO PAINTING. WHEN THESE CAUSTIC OR ACID SOLUTIONS BECOME CONTAMINATED AND MUST BE DISPOSED, THE WASTE WOULD BE A CORROSIVE HAZARDOUS WASTE.

CERCLIS-NFRAP: CERCLIS No Further Remedial Action Planned Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site.

RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. RCRAInfo replaces the data recording and reporting abilities of the Resource Conservation and Recovery Information System (RCRIS). The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Conditionally exempt small quantity generators (CESQGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month. Large quantity generators (LQGs) generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg of acutely hazardous waste per month. Transporters are individuals or entities that move hazardous waste from the generator off-site to a facility that can recycle, treat, store, or dispose of the waste.

US BROWNFIELDS: A Listing of Brownfields Sites Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA’s Targeted Brownfields Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified brownfields-related cleanup activities.

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.
