Portland, Oregon SUBJECT:Soil Management Protocols and Summary of Site Investigations for Persistent Agricultural Chemicals, Proposed Tigard Library Site, 13360-13560 SW Hall Boulevard, Tigard, Oregon Herein, Hahn and Associates, Inc. (HAI) summarizes the results of investigation activities conducted to assess for persistent agricultural chemicals in the near surface soils of the above-referenced site. In addition, HAI presents comments on potential site development issues relating to the presence of elevated arsenic levels in the soils at the site, and provides recommendations and options for management of soils containing elevated arsenic as part of future site re-development activities. Investigations SummarX In July 2002, a Phase I Environmental Site Assessment (ESA)' of the subject property revealed that the central portion of the subject property was formerly used as an orchard from at least 1940 until 1953. In September 2002, Phase-II ESA' activities were conducted to determine if persistent agricultural chemicals may be present in the near- surface soils of the property. This testing did not identify the presence of chlorinated pesticides or herbicides in orchard area soils. However, arsenic was detected in soil at concentrations above risk screening levels [U.S. Environmental Protection Agency (EPA) Region 9 Preliminary Remedial Goals (PRGs) for residential and industrial soils]. Arsenic, although a naturally-occurring element, was identified at concentrations exceeding typical natural background levels in area soils [typically below 7 parts per million(ppm)]. The 7 ppm regional background concentration for arsenic in soil is supported by a study conducted by the Department of Ecology (DOE) for soils in Washington State 3, as well as ' Hahn and Associates, Inc.

Further, in an October 28, 2002 Memorandum from the Oregon Department of Environmental Quality (DEQ) Toxicology Workgroup, 7 ppm was identified as appropriate for use as a default background arsenic concentration for soils in Oregon. —. In January, February, and April 2003, additional testing of near-surface soils for arsenic was conducted in areas of the site that may be disturbed as part of the proposed library development. This testing included detailed vertical profiling to determine depths of elevated arsenic presence within the soil profile, as well as collection of samples at additional locations to determine the lateral extent of elevated arsenic levels in the area of proposed development. Vertical profiling revealed arsenic is typically found at the highest concentrations in the upper one foot of soil at portions of the site, while lesser concentrations are typically present in the second foot of soil, but still exceeding the default background level. In most instances, arsenic levels were found to drop to below levels of detection at depths greater than 2 feet bgs, although slightly elevated levels were identified at one location beneath this depth (10.2 ppm from 2 to 3 feet bgs at sample location SS-44). In total, arsenic was detected at concentrations above typical background levels in 39 of 105 soil samples that were tested at the site, at concentrations up to 107 ppm. Table 1 (attached) is a summary of all soil testing conducted to date for arsenic and other persistent agricultural chemicals at the property. Laboratory analytical reports and chain-of-custody documentation for all testing activities conducted subsequent to the referenced Phase II ESA activities, have also been attached herein. An interpretation of arsenic extent in soil is shown on Figure 1 (attached). Of note, arsenic was not found throughout the former orchard area at elevated levels. In addition, elevated arsenic was found in areas that were not thought to be historical orchards. Instead, the elevated arsenic in near surface soil appears to better correlate with swales and low-lying areas of the site. Within the developable portion of the property, elevated arsenic appears to be limited to a south to north sloping Swale at the central portion of the site and a connected east to west sloping Swale near the southern property boundary. Both swales are joined upslope near the southwestern property boundary, with the overall Swale extending off-site to the southwest. Erosion and overland transport of arsenic within soil, with deposition in low-lying areas, may explain the observed pattern of arsenic at the site. Although the specific source of the elevated arsenic is not known, the greatest concentrations on the property (91.3 to 107 ppm) were found in the vicinity of a former structure (barn?) located on the southernmost parcel near the confluence of the swales, as observed on historical aerial photographs and as depicted on Figure 1. It is possible that pesticide storage, mixing, and/or equipment rinsing may have occurred at the location of the former structure, which may explain the presence of arsenic in the non-orchard Swale. Alternatively, or in addition, because the Swale extends up-slope and off site to the southwest, it is possible that run-off from orchards formerly located to the southwest of the property may have contributed to the identified arsenic impacts. In summary, testing results indicate the vertical extent of elevated arsenic is predominantly limited to the upper two to three feet of soil at the site, and the lateral ' Schaklette, H.T., and Boernegen, J.G. (1984). Element Concentrations in Soils and Other Surficial Materials of the Conterminous United States (U.S. Geological Survey Professional Paper 1270). HAHN AND ASSOCIATES, INC. Technical Memorandum Page 3 of 5 Recommended Soil Management Protocols Project No. 5927 Proposed Tigard Library Site April 25, 2003 Tigard, Oregon i extent of elevated arsenic (i.e., greater than 7 ppm) is present predominantly in swales _ and low-lying areas of the site, as delineated on Figure 1. It is of note that the full lateral extent of elevated arsenic has not been determined in those portions of the site that are within the flood plain and are not proposed for development. Testing of select soil samples by Synthetic Precipitation Leaching Procedure (SPLP) and Toxicity Characteristic .-. Leaching Procedure (TCLP) indicates concentrations of leachable arsenic were not detected, indicating that arsenic leaching to groundwater is not a migration pathway of concern, and that excavated soils would not meet criteria for defining a characteristic hazardous waste through the Resource Conservation and Recovery Act (RCRA). Regulatory Issues As long as the property remains in agricultural use, no actions are necessary with respect to the arsenic in soil. However, because of the proposed change in land use at the site, Oregon's Hazardous Substance Remedial Action rules (OAR Division 122) will likely require actions to address the elevated arsenic in soil. For a metal such as arsenic in near surface soil, the typical remedial actions are access restrictions, removal, and/or capping. There is no requirement to report the site to the Oregon Department of Environmental Quality (DEQ), and all remedial actions can be conducted as an Independent Cleanup without DEQ oversight, as long as they meet the cleanup rule requirements. However, to obtain official "No Further Action" designation for the site, DEQ involvement would be necessary. Remedial Action Approach and Development Issues A conceptual remedial action approach that seems to best fit the development plans for the property is composed of the following elements: 1) Removal — For those areas with elevated arsenic (greater than 7 ppm on Figure 1), every effort should be made to minimize the volume of soil that needs to be removed as part of site development for surface preparation. We understand that at least the upper 6 inches of soil will need to be removed. This soil should be sent to an appropriate landfill for disposal, or used on-site as fill. If used on-site, the areas of filling will need to be carefully documented, and covered with an impermeable cap (pavement or building foundation) or cap of clean fill. Specific soil management protocol recommendations are provided in the following Section. 2) Capping— For those areas of elevated arsenic located within the developed portion of the site following site grading (greater than 7 ppm on Figure 1), a cap of clean soil, pavement, or a structure should be installed and maintained. Controls should _ be in place to ensure future excavation workers (e.g., utility line construction or repair) who may penetrate the cap are aware of special precautions and soil management procedures that may be necessary. HAHN AND ASSOCIATES, INC. Technical Memorandum Page 4 of 5 Recommended Soil Management Protocols Project No. 5927 Proposed Tigard Library Site April 25, 2003 Tigard, Oregon _ 3) Access Restrictions — For those areas of elevated arsenic located outside the developed portion of the site, some sort of access restriction may be the most appropriate approach. Because the extent of elevated arsenic outside the portion of the site to be developed (within the wetland boundary)has not been delineated at this time, it is recommended that access to surficial soils should be restricted throughout this area. Recommended Protocols for Management of Contaminated Media 1) Those personnel conducting activities on-site for which potential exposure to contaminants exists should be in compliance with all federal and state rules and regulations, including rules promulgated by the Occupational Safety and Health Administration, Code of Federal Regulations (CFR), Title 29, Part 1910.120, and the substance-specific Construction standards (inorganic arsenic) contained in 437 r Division 2, 1910.1018. 2) The Oregon Occupational Safety and Health Agency (OR-OSHA) permissible exposure limit (PEL) for arsenic is 10 micrograms per cubic meter (µg/m3) of air, averaged over an eight-hour period. OR-OSHA also defines a regulatory action level for an eight-hour time-weighted average (TWA). The action level for arsenic is 5 µg/m3. The need for, and design of, air quality monitoring to ensure adherence —' with the arsenic PEL and action level should be determined by the earthwork contractor. However, air monitoring during grading or excavation activities in the area of elevated arsenic concentrations (Figure 1) to document a lack of worker inhalation hazard and the adequacy of engineering controls (dust suppression) is recommended. 3) Dust controls should be implemented during earthwork or other construction activities, as necessary, such that dust generation is minimized and to prevent off- site migration of dust. Dust controls could include use of water trucks to moisten roads and other areas that could generate dust. Further, construction vehicle speed limits and/or placement of gravel in heavily traveled areas could be used. Additionally, during dry weather, the use of compressed air for dust removal or equipment cleaning could be prohibited. Finally, earthwork equipment and trucks should be inspected and rinsed via wheel wash stations, as necessary, prior to leaving the site to prevent spreading of site soil to nearby public streets. 4) If excavated soils from an area documented as containing greater than 7 ppm arsenic (Figure 1) are to be temporarily stockpiled on site, then the stockpile(s) should either remain within the area depicted on Figure 1 as containing elevated arsenic levels (i.e., greater than 7 ppm), or else the stockpiles should be placed on a minimum of 6 mil geomembrane to prevent mixing with the underlying soil. Dust suppression measures, such as covering, should be implemented for the stockpiles to prevent generation of windblown dust. HAHN AND ASSOCIATES, INC. Technical Memorandum Page 5 of 5 Recommended Soil Management Protocols Project No. 5927 Proposed Tigard Library Site April 25, 2003 Tigard, Oregon 5) Soil excavated from areas delineated on Figure 1 as containing arsenic at concentrations greater than 7 ppm will require either on-site restricted subgrade use, or off-site disposal in a lined landfill permitted by the DEQ to accept non- hazardous contaminated soil wastes. Permitting and pre-approval from the disposal facility will be necessary prior to implementing the landfill disposal option. On-site reuse should be restricted to placement below pavement, buildings, or below a minimum of 3 feet of clean fill in those areas that will not be covered with pavement or structures (or other impermeable cover). A preference should be given to reuse as subgrade backfill within the presently delineated area identified as having arsenic concentrations greater than 7 ppm. 6) A distinct geotextile marker should be used to delineate the boundary between soils containing greater than 7 ppm arsenic and the overlying material [either non-impacted soil or and impermeable barrier (e.g., structure or pavement)]. The geotextile marker will act as a physical indicator to future excavation workers as to the location arsenic-impacted soil. 7) The location and extent of all geotextile markers should be documented during construction and permanently recorded. This documentation, in addition to the physical presence of the geotextile marker, can be used as a planning tool and control with regard to future excavation activities that could encounter soils containing arsenic at concentrations greater than 7 ppm.
