Subject: Soil Sampling Results Report
Proposed Ukiah Riverside Park
Ukiah, California
Dear Ms. Irace:

Environmental Science Associates (ESA) conducted a soil investigation at the proposed Ukiah Riverside Park in Ukiah, California, on behalf of the City of Ukiah and in accordance with our proposals dated March 2, 2022, and May 19, 2022. The project site is predominantly undeveloped land that the City is considering developing as a park with wetlands. The purpose of the soil sampling and analysis is to inform the project design.

Site History
According to a 1999 Phase I environmental site assessment, the project site was previously used for sewage treatment ponds from the 1930s to 1958, as identified in Figure 1. A trap shooting range (Ukiah Rod & Gun Club) from at least 1968 to 1978 and a former police shooting range from 1968 to 1978 (Dannatt 1999) were previously located in the southern portion of the project site. A large pit in the central portion of the property was used to mine gravel from approximately 1981 until 1986. Since 1986, the pit area has been filled in with concrete, asphalt, street sweepings, and brush by a variety of agencies within the City and County (Public Works, Utilities, and County Roads). In addition, other areas of the project site have been used by the City for debris.

Unauthorized dumping of household debris has also occurred on the central and southern portions of the project site.

Screening Levels
The analytical testing results are tabulated on Tables 1, 2, 3, and 4 and discussed in the sections below. The results from the March 23, 2022, sampling event are tabulated on Tables 1, 2, and 3, and identify the chemicals of concern. The May 26, 2022, sampling event tested only for the chemicals of concern identified during the March 23, 2022, sampling event. The results of both sampling events for the chemicals of concern are tabulated on Table 4.

The metals results are first compared to background levels from published studies to identify those chemicals that are present at naturally occurring background levels. General background levels are available from the Kearney Foundation: Background Concentrations of Trace and Major Elements in California Soils, dated March 1996.

Only those metals that exceed background levels are evaluated further. All results are compared to the California Code of Regulations (CCR) Title 22 Total Threshold Limit Concentrations (TTLCs) to assess whether onsite soils would be considered a hazardous waste if disposed of at an offsite landfill permitted to accept the waste.

Page 764 of 1237 ends

June 5, 2022

All results are compared to the 2019 Environmental Screening Levels (ESLs) developed by the San Francisco Bay Regional Water Quality Control Board (RWQCB 2019). ESLs are screening levels used by regulatory agencies throughout the state to assess whether further investigation and possibly cleanup is needed at sites where hazardous materials are suspected to have been spilled. ESLs are risk-based levels based on both human health and ecological habitat, which can provide comparative guidance as to whether a given chemical is present in soil at levels that might pose risks to construction workers, the public, or the environment. Tables 1, 2, and 3 use the terrestrial ESLs, which are ecological screening levels that are lower than the construction worker ESLs. Table 4 includes both the terrestrial and construction worker ESLs for the results from both sampling events. Note that the proposed project would result in a wetland environment for which the beneficial reuse screening criteria discussed below would provide more relevant guidance.

All results are compared to the 2000 RWQCB Beneficial Reuse of Dredged Materials: Sediment Screening and Testing Guidelines, dated May 2000. Beneficial reuse screening criteria are ecological acceptance criteria used by the San Francisco RWQCB to assess whether fill would be acceptable for use in restoring wetlands and levees on the margins of San Francisco Bay. The screening criteria include surface and foundation beneficial reuse screening criteria. Surface beneficial reuse screening criteria are more stringent and apply to the top three feet of materials. Foundation beneficial reuse screening criteria are less stringent and apply to material buried under three feet of surface beneficial reuse material. Although the Riverside Park project would not import fill materials, the screening criteria provide a useful comparison to assess whether the onsite materials would be acceptable in a wetlands environment.

March 23, 2022, Sampling Event
Sampling and Laboratory Analysis
Using the information acquired from the 1999 Phase I assessment, historical aerial photographs, and topographic maps, ESA collected and chemically analyzed four shallow (i.e., 6 to 12 inches in depth) soil samples on March 23, 2022, at the locations shown on Figure 1. Samples S-1, S-2, and S-3 are located within the footprint of the former sewage treatment ponds. Sample S-4 is located in the area of the former trap shooting range and former police shooting range.

The samples were collected at about 6 to 12 inches below the ground surface using a shovel and trowel. The soil samples were sealed in their sampling containers, labeled with a unique identification number, placed in an ice chest with ice for preservation, and delivered on the same day to McCampbell Analytical Laboratory, a statecertified analytical laboratory, along with chain-of-custody documentation. The soil samples were analyzed for the following chemicals using the cited methods:
 Total petroleum hydrocarbons (TPH) as gasoline, diesel, and motor oil by EPA Method 8015Bm  Volatile organic compounds (VOCs) by EPA Method 8260B  Semivolatile organic compounds (SVOCs) by EPA Method 8270C  Organochlorine pesticides and polychlorinated biphenyls (PCBs) by EPA Method 8081A/8082  CAM 17 metals (antimony, arsenic, barium, beryllium, cadmium, cobalt, chromium, copper, lead, total mercury, molybdenum, nickel, selenium, silver, thallium, vanadium, and zinc) by EPA Method 6020

Analytical Results and Screening Criteria
The March 23, 2022, sampling event laboratory analytical report is provided in Appendix A. The chemical results are tabulated on Tables 1, 2, and 3, along with the relevant screening criteria. Only those chemicals with at least one detection above laboratory reporting limits are listed; chemicals with no results above laboratory reporting limits are not listed and are concluded to be below all screening criteria.

Discussion
Hazardous Waste Levels
None of the reported concentrations of chemicals in soil exceeded their respective TTLCs for those chemicals that have listed TTLC values. Based on the analytical results, the soil would not be considered hazardous waste and could be accepted at any Class III non-hazardous waste landfill, if offsite disposal is considered.

Volatile and Semivolatile Organic Compounds, and Petroleum Hydrocarbons The results for volatile and semivolatile organic compounds, and petroleum hydrocarbons are tabulated on Table 1. None of the reported concentrations exceeded any screening criteria. These suites of chemicals are more volatile; the low to non-detectable results do not indicate a respiratory risk to construction workers or the public.

The low to non-detectable results for these chemicals also indicate no risk to the environment.

Metals
The results for metals are tabulated on Table 2. Lead and selenium were the only metals detected above background levels and only at the location of Sample S-2. The concentration of selenium in Sample S-2 did not exceed the terrestrial ESL or surface or foundation beneficial reuse screening criteria, indicating that the soil in this location does not pose a risk to construction workers, the public, or the environment relative to selenium.

The concentration of lead at the location of Sample S-2 exceeded both the terrestrial ESL and the surface beneficial reuse criteria. If the soil at this location were excavated and mixed with soil from the rest of the property during grading, the average concentration would be 63.25 milligrams per kilogram (mg/kg), which would still exceed both the terrestrial ESL and the surface beneficial reuse criteria. From the perspective of beneficial reuse and protection of the environment, the soil at the location of Sample S-2 would qualify for use as foundation material, meaning that if this area where covered with or moved to an area that could be covered with three feet of soil that meets surface beneficial reuse screening criteria, the covered soil would not be expected to pose a risk to construction workers, the public, or the environment.

Organochlorine Pesticides and PCBs
The results for organochlorine pesticides and PCBs are tabulated on Table 3. PCBs were not detected above laboratory reporting limits and are assumed to be at concentrations below all screening criteria since there are no detections above the laboratory reporting limit.

Page 766 of 1237 ends

June 5, 2022

Page 4 ends

The pesticides chlordane (both a-chlordane and g-chlordane) and DDT and its degradation products of DDD and DDE are the only organochlorine pesticides detected above laboratory reporting limits and only at the locations of Samples S-1 and S-2.

The concentration of a-chlordane and g-chlordane at the location of Sample S-2 exceeded the terrestrial ESL and both the surface and foundation beneficial reuse screening criteria. This indicates that soil in the area of Sample S-2 would pose a risk to the environment. Note that the concentrations of chlordane do not exceed construction worker ESLs. The sample at S-1 did not have chlordane above laboratory reporting limits.

To assess the average chlordane concentration that would result from grading and mixing soil throughout the project site, the average concentrations of all four samples are included in Table 3, using one-half of the laboratory reporting limit for those results reported at below reporting limits. If mixed through grading of the property, the average concentrations of a-chlordane and g-chlordane would be 0.0057 mg/kg and 0.0048 mg/kg, respectively. The average concentrations would be below the chlordane terrestrial ESL of 0.00853 mg/kg, but would still exceed both the surface and foundation beneficial reuse screening criteria of 0.0023 mg/kg and 0.0048 mg/kg, respectively. This indicates that mixing soil from the area of Sample S-2 with soil throughout the project site would still result in soil unsuitable for beneficial reuse in a wetland environment.

The concentrations of DDT at the locations of Samples S-1 and S-2 exceeded the terrestrial ESL and both the surface and foundation beneficial reuse screening criteria. In addition, the average total DDT concentration (i.e., sum of DDD, DDE, and DDT) of 0.0449 mg/kg would still exceed the ESL of 0.0011 mg/kg and the surface beneficial reuse screening criteria of 0.007 mg/kg, but not the foundation beneficial reuse screening criteria of

0.0461 mg/kg. This indicates that soil in the area of Samples S-1 and S-2 would be unsuitable for beneficial reuse in a wetlands environment unless removed or covered with three feet of clean fill.

Summary
The areas around Samples S-3 and S-4 do not have chemical concentrations that exceed guidance levels, indicating that soil in the southern portion of the property would have no restrictions on its use. The areas around Samples S-1 and S-2 in the northern portion of the property have chemical concentrations that would restrict the reuse of soil. The concentrations of chlordane and DDT in soil at the area around Sample S-2, and to a lesser extent DDT in Sample S-1, indicate soil in these local areas may be unsuitable for use as a public park and as a wetland habitat in their present condition. Options for addressing this condition could include the following:
 Move or dispose of the soil: If soil in the area around Samples S-1 and S-2 is to be graded and moved, the soil could be excavated and disposed of at any Class III non-hazardous waste landfill. Alternately, the excavated soil could be placed in other onsite areas, provided the soil is covered with three feet of clean soil to isolate the contaminated soil from the public and the environment. It is unknown whether chlordane and/or DDT are present in the surrounding or deeper soil at concentrations that exceed screening criteria. To further characterize the extent and depth in the area around Samples S-1 and S-2, additional samples could be collected and analyzed for organochlorine pesticides and lead.

Page 767 of 1237 ends

Page 5 ends

 Cover the soil: Alternately, the project design could be modified to cover the area around Samples S-1 and S-2 with three feet of clean fill to isolate the contaminated soil from the public and the environment.

After discussion of the results with the City and Patrick Ferrar of the Melton Design Group, the project team decided to conduct a second sampling event in the area around the location of Sample S-2 to assess whether the location of Sample S-2 is an isolated hot spot or an indication of a more extensive area of material that will not be suitable for beneficial reuse.

May 26, 2022, Sampling Event
Sampling and Laboratory Analysis
Using the information acquired from the March 23, 2022, sampling event, ESA collected and chemically analyzed nine additional soil samples on May 26, 2022. Four sample locations were sampled at distances of 50 feet radially out from Sample S-2 at the locations shown on Figure 1, with one shallow (one foot) and one deeper sample collected at each location. The deeper sample depths were based on the proposed depth of excavation of the restoration project, as summarized below.

The samples were collected using a shovel and trowel. The soil samples were sealed in their sampling containers, labeled with a unique identification number, placed in an ice chest with ice for preservation, and delivered on the same day to McCampbell Analytical Laboratory, a state-certified analytical laboratory, along with chain-ofcustody documentation. The soil samples were analyzed for the chemicals of concern that were identified during the first sampling event using the cited methods as listed below:
 Organochlorine pesticides by EPA Method 8081A
 Lead by EPA Method 6020
Analytical Results and Screening Criteria
The May 26, 2022, sampling event laboratory analytical report is provided in Appendix B. The chemical results are tabulated on Table 4 and include the March 23, 2022, results for organochlorine pesticides and lead. Only those chemicals with at least one detection above laboratory reporting limits are listed; chemicals with no results above laboratory reporting limits are not listed and are concluded to be below all screening criteria.

Lead
The concentrations of lead in Samples S-2-1 and S-2-SE-1 exceeded background levels. However, all other sample results are within background levels. Consequently, when the concentrations of lead in all 13 samples are averaged, the average concentration is 81.46 mg/kg, which would decrease to within background levels.

However, although the overall concentrations of lead are typical of background levels, the concentration of 480 mg/kg at Sample S-2-SE-1 does exceed the ESL of 160 mg/kg for construction workers. As discussed below, the concentrations of organochlorine pesticides in some soil locations exceeds some regulatory action levels and such soil is recommended for offsite disposal. To address construction worker safety, it is recommended that the soil at Sample S-2-SE-1 (one foot depth) and radially outward for 25 feet also be removed and disposed of offsite. It is further recommended that dust suppression measures be implemented when excavating in the area of Sample S-2 and the four step-out sample locations.

The concentration of lead at the location of Sample S-2-1 and S-2-SE-1 exceeded both the ESL and the surface beneficial reuse criteria. If the soil at this location were excavated and blended with soil from the rest of the property during grading, the average concentration would be 81.46 mg/kg, which would still exceed both the terrestrial ESL and the surface beneficial reuse criteria. As discussed below, the results of the organochlorine pesticide analyses also indicate some soil should be removed and disposed of.

Organochlorine Pesticides
The results for all organochlorine pesticides analyses are tabulated on Table 4. The pesticides chlordane (both achlordane and g-chlordane) and DDT and its degradation products of DDD and DDE are the only organochlorine pesticides detected above laboratory reporting limits. The only detected concentrations that exceed any screening criteria are at the locations of Samples S-1, S-2, and S-2-NE.

The concentration of a-chlordane and g-chlordane at the location of Sample S-2-1, the shallow sample collected during the March 23, 2022, sampling event, is the only location and depth that exceeded the terrestrial ESL and both the surface and foundation beneficial reuse screening criteria. This indicates that the shallow soil at Sample S-2-1 is not suitable for beneficial reuse in the proposed wetland environment. Note that a-chlordane and g-chlordane were not detected above reporting limits in any other sample, indicating that the shallow soil at S-2-1 is an isolated hot spot relative to chlordane. As discussed below, the Sample S-2 location also has exceedances of DDT screening criteria.

Page 769 of 1237 ends

June 5, 2022

Page 7 ends

DDT, the DDT degradation isomers of DDD and DDE, and total DDT (DDD plus DDE plus DDT) were detected at concentrations that exceed the terrestrial ESL and both the surface and foundation beneficial reuse screening criteria in Sample S-2-1. This location has the highest concentration of organochlorine pesticides of any of the samples. The deeper sample at S-2-2 did not detect any organochlorine pesticides, a pattern typical of all other sample locations.

The step-out sample location at S-2-NE also has DDD, DDE, and DDT at one foot and DDE at 2 feet in depth.

However, only the concentration of DDT at the one foot depth exceeds the terrestrial ESL; no other screening levels were exceeded, including the surface and foundation beneficial reuse criteria.

During the construction of the park, the grading and rearranging of topography of the project site would have the effect of blending the soil and generally averaging chemical concentrations. The average Total DDT concentration of for all 13 samples would be 0.0144 mg/kg, which would still exceed the terrestrial ESL and both the surface and foundation beneficial reuse screening criteria. This indicates that blending the soil at Sample S-2-1 with other onsite soil will not result in the average onsite DDT concentration decreasing to within acceptable beneficial reuse levels. If the shallow soil at Sample S-2 were excavated and disposed of at an offsite disposal location, the average DDT concentration would decrease to 0.00238, which would within both surface and foundation beneficial reuse screening criteria. Although the average concentration would exceed the terrestrial ESL, the surface and foundation beneficial reuse criteria are more appropriate for use in a wetland environment. Note that the removal of this soil would also remove soil with elevated concentrations of chlordane and lead. This indicates that the removal and offsite disposal of the top one foot of soil at the location and for about 25 feet around Sample S-2 would enable to beneficial reuse of all other onsite soil.

Summary and Recommendations
The areas around Samples S-1, S-3, and S-4 do not have chemical concentrations that would restrict the beneficial reuse of soil. The area around Sample S-2 has chemical concentrations that would restrict the reuse of soil. The concentrations of chlordane, DDT and its isomers, and lead in soil at the area around the location of Sample S-2, and to a lesser extent Sample S-2-SE-1 (due to lead), indicate soil in this limited area is are unsuitable for beneficial use as a public park and as a wetland habitat. To eliminate unsuitable soil, it is recommended that all soil at a 25 foot radius around the locations of S-2, S-2-NE, and S-2-SE be excavated and disposed of as Class III non-hazardous waste. Alternately, the City may have other construction projects where the excavated soil could be placed under an area to be covered with pavement or concrete to prfevent exposure to people and rthe environment.

* STLC and TCLP extractions require 2 days to complete; therefore, all TATs begin after the extraction is completed (i.e., One-day TAT yields results in 3 days from sample submission).

NOTES:
- MAI assumes that all material present in the provided sampling container is considered part of the sample - MAI does not exclude any material from the sample prior to sample preparation unless requested in writing by the client.

U** = An unpreserved container was received for a method that suggests a preservation in order to extend hold time for analysis.

WHERE GRADE CHANGES MUST OCCUR WITHIN THE DRIPLINE, A SUITABLE MITIGATION PLAN SHALL BE DEVELOPED BY EITHER A CERTIFIED ARBORIST. THE PLAN SHALL PROTECT THE TREE FROM EXCESS FILL AND/OR THE REMOVAL OF EXCESS SOIL FROM THE ROOT ZONE. 3. PRIOR TO THE BEGINNING OF CONSTRUCTION, EXISTING TREES SHALL BE PRUNED TO REMOVE LIMBS WHICH MAY BE DEAD OR MAY BECOME DAMAGED DURING CONSTRUCTION. PRUNING SHALL BE PERFORMED CONSISTENT WITH ANSI A300 PRUNING STANDARDS, PRUNE TO THIN 1 IN. 4. A TEMPORARY CONSTRUCTION FENCE SHALL BE INSTALLED AROUND ALL TREE TRUNKS WITHIN CONSTRUCTION ZONE. WRAP TRUNK 4 TIMES AND SECURE FENCING TO TRUNK FOR DURATION OF PROJECT. CONFIRM WITH LANDSCAPE ARCHITECT ON BOUNDARY. THE FENCE SHALL BE SUBSTANTIAL ENOUGH TO RESTRICT ACTIVITY TO OUTSIDE THE AREA AND SHALL BE INSTALLED PRIOR TO ANY GRADING OR OTHER CONSTRUCTION ACTIVITY. DURING CONSTRUCTION, MAINTENANCE SHALL BE PERFORMED SO THAT THE FENCE REMAINS IN GOOD REPAIR. REMOVAL OF THE FENCE SHALL ONLY OCCUR TO ALLOW REQUIRED CONSTRUCTION WITHIN THE AREA OR TO COMPLETE SITE LANDSCAPING. THE LANDSCAPE ARCHITECT SHALL BE CONTACTED, PRIOR TO COMMENCEMENT OF CONSTRUCTION, TO INSPECT FENCING AND TO APPROVE ANY CONSTRUCTION WITHIN THE DRIPLINE. 5. TREES TO BE RETAINED SHALL BE PROTECTED BY CONSTRUCTION FENCING AT THE DRIPLINE. CONSTRUCTION FENCE SHALL BE 4 FT.
