1 1.0 INTRODUCTION
This report presents the results of our geotechnical engineering investigation performed for the proposed Project in the City of Cudahy (City), California. The Vicinity Map, Figure 1, shows the site location.

The Project involves in design and construction of a new performing arts stage, outdoor gym with exercise stations and shade, walking loop/jogging path, splash pad with shade, shaded picnic shelter, and shaded picnic area, and new lighting and landscaping throughout the park. It will renovate four basketball courts, a baseball field with shade structures, playground, skate park, and tennis court as well. This report includes our geotechnical findings, and recommendations as a basis for the design and construction of the Project. The recommendations provided within this submittal are based on the results of our limited field exploration, laboratory testing, and engineering analyses.

2.0 SCOPE OF SERVICES
Our services evaluated the geotechnical conditions at the site and provided geotechnical design recommendations for the Project. Our scope of services included the following:
 A site reconnaissance by a member of our engineering staff to evaluate the present conditions at the project location;
 Review of selected published geologic maps and reports pertinent to the site and surrounding area;
 Field investigation consisting of drilling two (2) hollow stem auger boring holes for soil exploration to a depth of 20 feet below the existing ground surface (bgs) each and one boring for conducting one (1) percolation test to a depth of 5 feet bgs on the aforementioned locations;
 Laboratory testing on the pertinent samples obtained from the borings and interpretation of the test results to determine the physical and engineering properties of the subsurface soils;  Composite soil testing on the soil cuttings retrieved during field drilling and disposal of the soil cuttings per CA State Regulations;
 Engineering analyses and evaluation of the data obtained from the field investigation and laboratory testing program; and
 Preparation of this report, presenting our findings, conclusions, and recommendations for design and construction of the Project from a geotechnical viewpoint.

2 soil corrosivity have been limited to screening two representative soil samples collected from within the near-surface zone.

3.0 SITE DESCRIPTION AND PROPOSED DEVELOPMENT
The proposed Project is located at Cudahy Park at Santa Ana St in the City of Cudahy, California.

Primary access to the site is Santa Ana St to the west of the park and public parking is available on the north side of the park. The elevation of the site is approximately between 111 feet and 114 feet above mean sea level (MSL). The Project is proposed to renovate four basketball courts, a baseball field with shade structures, a playground, skate park, and tennis court as well. The latitude and longitude at the approximate center of the project site are 33.9587 N and 118.1736 W, respectively.

4.0 GEOLOGIC CONDITIONS

4.1 REVIEW OF REGIONAL DATABASE AND PREVIOUS STUDIES
Review of the CDMG Seismic Hazard Zone Report for the project area (CDMG, 1998, South Gate Quadrangle), indicates that historically high groundwater in the vicinity of the project site may have been within 8 feet of ground surface. The project area is in a liquefaction hazard zone as mapped by the CGS.

Review of previous reports available online at the California Geotracker Database indicates that previous borings advanced about ¼- to ½-mile west of the project site encountered primarily silty sand to sandy soils in the upper 25 feet with primarily sandy soils with interlayered clay lenses from 25 to 75 feet. Borings reviewed on the GeoTracker database from about 1995 to 2010 reported groundwater at a depth of about 50 to 55 feet.

4.2 GEOLOGICAL SETTING
The project site is in Cudahy along the western side of the north-south trending Los Angeles River (LAR) channel about 13 miles north of the Pacific Ocean. The topography in the study area slopes gently southward, generally parallel to the LAR channel.

The present-day Los Angeles Basin is a northwest-trending alluvial plain about 50 miles long and 20 miles wide, on the coast of Southern California, bounded on the north by the Santa Monica Mountains and the Elysian, Repetto, and Puente Hills and on the east and southeast by the Santa Ana Mountains and San Joaquin Hills. The low land surface slopes gently south or seaward, interrupted by the Coyote Hills near the northeast margin, a line of elongated low hills to the south and west that extend from Newport Bay northwest to Beverly Hills, and by the Palos Verdes peninsula along the southwestern extremity.

Structurally, Norris and Webb (1990) indicate the Los Angeles Basin is divided into four major blocks comprising a complex assemblage of uplifted blocks and lowered depressions. The physiographic basin is underlain by a structural depression, parts of which have been the sites of Cudahy Park Renovation Project, Project # PRE-001 Document Control 127 of 1214 Page 157 of 1692 Updated Draft Geotechnical Investigation Report

3 discontinuous deposition since Late Cretaceous time and of continuous subsidence and chiefly marine deposition since middle Miocene time. The most distinctive geologic characteristic of the Los Angeles Basin is its structural relief and complexity in relation to its age and size. Continuous subsidence and deposition in late Miocene and Pliocene time caused variations in lithology and thickness in most of the sedimentary rock units; contemporaneous folding and faulting along with erosion resulted in numerous regional and local unconformities, disconformities, and stratigraphic discontinuities across faults. The Los Angeles Basin is one of California’s most prolific oilproducing districts in proportion to its size.

4.3 LOCAL GEOLOGY
Geologic mapping by CDMG (1999) indicates the near surface deposits in the project area consist of Younger Holocene Age (Qya2) alluvial deposits from the Los Angeles River (Figure 2 – Regional Geologic Map). CDMG describes the alluvial deposits in the project area as loose to medium dense, very coarse- to very fine- grained sand, gravel, and silt that appear to interfinger and grade laterally into each other.

4.4 REGIONAL AND LOCAL FAULTS
The project site is located in seismically active southern California and is expected to experience ground shaking from future earthquakes. Such earthquakes can occur on several active faults within the region. Jennings and Bryant (2010), the USGS, and the CDMG (1999, now California Geologic Survey, CGS) have mapped faults and identified fault activity in the region. Active and major faults mapped in the project vicinity are shown on Table 1 Nearby Faults.

The CGS defines active and potentially active faults in the Alquist-Priolo (AP) Geologic Hazard Zone Act (1994). Active and potentially active faults are defined as those that ruptured during the Holocene (10,000 to 11,000 years ago) and Quaternary (1.5 million years ago) periods, respectively. The CGS has published maps of Earthquake Fault Zones following the AP Geologic Hazard Zone Act, 1994, which regulates developments near active faults. Based on our review of these maps, the site does not lie within an AP Zone. However, the seismic risk is considered relatively high because of the proximity to active faulting. The closest mapped active faults by the California Geologic Survey (that are exposed at the ground surface) relative to the project site are the Newport-Inglewood and Whitter faults, located approximately 6.7 and 7.6 miles south and northeast of the project site, respectively. The other faults listed in Table 1 consist of buried thrust faults that are not exposed at the ground surface.

5.0 GEOTECHNICAL INVESTIGATIONS

5.1 FIELD EXPLORATION
Field exploration for this investigation consisted of drilling two (2) Hollow Stem Auger (HSA) borings to a depth of 21.5 feet bgs each for soil sampling and testing in addition to one HSA boring to a depth of 5 feet bgs for a percolation test as illustrated in Figure 3 Boring Location Map.

Relatively undisturbed, disturbed and bulk soil samples were collected from each soil boring during drilling. Bulk samples were collected from HSA cuttings obtained from within the nearsurface depths. At selected depths throughout the boring depths, disturbed and relatively undisturbed soil samples were collected by a split-spoon sampler and three-inch outside diameter Modified California Sampler lined with brass rings, respectively.

The explorations were visually classified and logged by a Willdan field engineer. Classification of the soils encountered in HSA borings was made in general accordance with the Unified Soil Classification System (USCS), using a visual-manual procedure (ASTM D2488) and/or based on laboratory testing (ASTM D2487). For a more detailed description of the soil conditions and depth and thickness, please refer to the boring logs in Appendix A. All drilled holes were backfilled with cement/slurry per the LA County Permit.

5.2 LABORATORY TESTING
Laboratory testing included determining in-situ moisture and dry density, sieve analysis, Atterberg limits, direct shear, consolidation, corrosion potential and expansion index for soil samples collected from various depths. Laboratory tests were conducted according to the American Society for Testing of Materials (ASTM) Standards or California Test Methods (CTM). Composite soil testing were conducted on soil cuttings retrieved during field drilling. All laboratory test results are summarized and presented in Appendix B, Laboratory Test Results. Note that soil cuttings are Cudahy Park Renovation Project, Project # PRE-001 Document Control 129 of 1214 Page 159 of 1692 Updated Draft Geotechnical Investigation Report

5 classified as CA Hazardous for Lead per the results of composite soil testing.

5.3 SUBSURFACE CONDITIONS
The HSA borings revealed the existing earth materials within the exploration depth consisted primarily of Fill and brown Silty to Clayey SAND and Sandy to Silty CLAY. The moisture content was tested to be between 9.4% and 24.4% with a degree of saturation ranging from 40.2% to

95.8%. The dry density of the soils is between 88.9 pound cubic feet (pcf) and 119.1 pcf.

5.4 GROUNDWATER
Groundwater was not encountered during the time of field exploration. The groundwater level will fluctuate in response to rainfall, seasonal climate variations, on-site irrigation, near-site development, and other factors. CDMG Seismic Hazardous Zone Report for the South Gate 7.5- Minute Quadrangle, Los Angeles County, California (1998) indicates that the historically highest groundwater level in the region of the Project site is at a depth of 8 feet bgs.

6.0 SEISMIC HAZARDS

6.1 SITE CHARACTERIZATION – SITE CLASS
The subsurface soil profile at the site can be classified from a seismic standpoint, based on the conditions encountered in all exploratory borings and anticipated within the upper 100 feet of the area based on geologic mapping, as being shallow alluvium extending over 100 feet. Based on the materials encountered at the subject site and considering the geologic units mapped in the area, our opinion is that the site soil profile corresponds to Site Class D, following Section 1613.2.2 of CBC 2022.

6.2 GROUND SHAKING
Although ground rupture is not considered a significant concern at the subject site per California Earthquake Hazards Zone Application (https://maps.conservation.ca.gov/geologichazards/ & https://maps.conservation.ca.gov/cgs/EQZApp/) , the site will likely be subject to moderate to severe seismic shaking during its lifetime. For this report, an acceleration of 0.899g and 0.79g may be used for the design maximum considered earthquake geometric mean (MCEG) peak ground acceleration adjusted for site class effects (PGAM) as detailed in Appendix C per ASCE 7-16 and 7-22, respectively (https://asce7hazardtool.online/).

6.3 SOIL LIQUEFACTION
Soil liquefaction is a temporary soil particle suspension caused by loss of strength due to pore pressure increase resulting from cyclic stress application induced by earthquakes and the resultant drop in effective stress and soil shear strength. Liquefaction commonly occurs in saturated granular soils, such as sands, where the strength is purely frictional. Soils most susceptible to liquefaction are saturated, loose, uniformly graded, fine-grained sand deposits. However, liquefaction has occurred in soils other than clean sands. Silty sands and sandy silts have also been reported to be susceptible to liquefaction or partial liquefaction. The occurrence of liquefaction is Cudahy Park Renovation Project, Project # PRE-001 Document Control 130 of 1214 Page 160 of 1692 Updated Draft Geotechnical Investigation Report

6 generally limited to soils located within the top 50 feet of the ground surface. Primary factors affecting the potential for soil to undergo liquefaction include:
1) Depth to groundwater;
2) Soil type;
3) Relative density of the soil and initial confining (overburden) pressure; 4) Intensity and duration of ground shaking.

Potential problems associated with soil liquefaction include ground surface settlement, loss of foundation-bearing support strength, and lateral spreading. While liquefaction occurs in confined sand layers, a phenomenon called sand boils may occur at the ground surface. Sand boils occur when groundwater’s sudden compression in a layer of saturated, clean, loose sand builds sufficient pressure to rupture through the upper soil mantle to the ground surface. When this occurs, the liquefied sand’s displacement results in the sudden loss of support of structures supported by shallow foundations.

The Project site has been mapped as being within a zone susceptible to liquefaction designated by the State of California (CGS, 1999), Liquefaction Hazards Zone Map. Based on the CGS’s SP117A, “The intent of the State's Seismic Hazard Map Zoning program is to ensure that a minimum level of public safety and protection is met for projects in zones of required investigation.

The acceptable level of risk by State standards is one that ensures life safety in most residential and commercial structures. Hospitals, schools and other essential services buildings are held to higher levels of operability and are inspected and reviewed using different standards.” Based on the conceptual project plans provided by Willdan Design team, this project does not include residential/commercial structures, and hospitals/schools/other essential services buildings.

However, for a peak ground acceleration of 0.60g corresponding to the 2/3 of the Full Peak Ground Acceleration (PGAM) obtained from ASCE Hazard Tool and a Groundwater Level (GWL) at a depth of 8 feet bgs and a Magnitude of 7.5, liquefaction-induced settlement at the site has been calculated to be on the order of 8 - 11.5 inches based on the soil profile encountered in Borings B1 and B-2. The corresponding differential liquefaction-induced settlement will be typically considered to be on the order of one-half (1/2) of the liquefaction-induced settlement, i.e., 4 to 5.8 inches. The results of liquefaction analyses suggest that liquefaction-prone soil strata exist on the site at depths from approximately 5 to 50 feet bgs in Borings B-1 and B-2. Due to the relatively large liquefaction-induced settlement and differential liquefaction-induced settlement, it is deemed geotechnically necessary to implement ground modification in site subgrade soils to mitigate the potentially significant ground hazards and allow for the construction of the following proposed features but not limited to:
• Electrical switchboard & transformer concrete,
• Storage building,

7 • Two 30-foot high flag poles,
• Community amphitheater,
• Community art mural wall,
• Shade canopies, and
• Field lightning.

Based on the liquefaction-induced settlement calculations, ground modification consisted of vibro stone columns (VSCs) or similar extending to 38 feet depth could reduce the post-ground modification liquefaction-induced settlement to 4.0 inches in Boring B-1, with the corresponding differential liquefaction-induced settlement reduced to 2.0 inches. The layout of VSCs should be in equilateral triangular pattern with a VSC diameter of three (3) feet spaced at an interval of six (6) feet center-to-center.

6.4 SURFACE FAULT RAPTURE
Because the active faults have not been identified near the site, we consider the potential for surface rupture from fault plane displacement propagating to the surface remote.

6.5 LATERAL SPREADING
Lateral spreading happens when surficial soil moves parallel to the ground surface due to the liquefaction of underlying subsurface soil layers. Lateral spreading usually occurs where the ground surface has a slope of less than 6 percent and may damage structures or other improvements due to differential lateral movements (Naeim, 1989). The potential for lateral spreading to occur at the project site during seismic events is low.

7.0 CONCLUSIONS AND RECOMMENDATIONS

7.1 GENERAL
Based on our geotechnical investigation, the proposed development is feasible from a geotechnical viewpoint, provided the recommendations in this report are implemented in the design and construction of the project. The following recommendations are based upon subsurface conditions encountered in our limited field investigation; these near-surface soil conditions could vary across the site. Variations in the soil conditions may not become evident until the commencement of grading operations for the proposed development and revised recommendations from the soils engineer may be necessary based upon the conditions encountered. It is recommended that site inspections are performed by the representative of a registered Geotechnical Engineer or Certified Engineering Geologist during all grading and construction of the development to verify the findings and recommendations documented in this report.

8 To mitigate potentially significant liquefaction-induced settlement at the site, the construction of the proposed features as listed in Section 6.3 including storage building and other improvements should adopt a composite foundation scheme consisted of a ground modification measure with vibro stone columns (VSCs) installed from the bottom of Geosynthetics-Reinforced Load Transfer Platform (GRLTP) layer that is five (5) feet in depth, to thirty-six (36) feet bgs and a GRLTP layer constructed over VSCs within the upper five (5) feet. By adopting these measures, the calculated liquefaction induced settlement associated with subgrade soils at the site could be significantly reduced that will subsequently allow the storage building and other improvements to be supported by conventional shallow footing foundation.

The following sections present a discussion of geotechnical related requirements for specific design recommendations of various aspects of the project.

7.2 EARTHWORK
Earthwork should be performed following the latest version of Standard Specifications for Public Works Construction (Greenbook 2021) and the City of Cudahy’s grading requirements.

Excavations and cuts should be inspected during grading.

7.2.1 Site Preparation
The contractor should take all necessary measures to protect existing utilities within the project limits during site preparations. All abandoned utilities encountered should be drained for all content, if any, and properly capped. Any existing foundations, shallow footings, piles, and grade beams, exposed during excavation/grading activities should be identified, analyzed for possible adverse effects and conflict with the new foundation, and, if necessary, removed and disposed of offsite.

The soils exposed under the existing ground surface may be used for support of the proposed foundation. Note that soil cuttings retrieved during our field investigation are classified as CA Hazardous for Lead as noted in Section 5.2.

If encountered, all undocumented fill and/or disturbed soil shall be removed to competent native materials, and the exposed surface should be scarified to a depth of 12 inches, brought to within 2% of optimum moisture content and compacted to a minimum of 90% of the laboratory standard (ASTM: D 1557) prior to placement of any additional compacted fill soils, foundations, slabs-ongrade and pavement. Grading shall extend a minimum of five horizontal feet outside the edges of foundations or equidistant to the depth of fill placed, whichever is greater.

If unsuitable soils are encountered, over-excavation should be performed to a minimum depth of 2 feet, measured from the bottom of the new foundation. The removal should extend at least 2 feet outside the perimeter of the proposed foundation, where feasible. After removing unsuitable soils and before placing any fill, the bottom of removal shall be observed and confirmed to be competent by the Geotechnical Engineer of Record. If the exposed subgrade soils are not stable and pumping, deeper removals may be required, or it may be improved by placing 1 to 2 feet of 2” crushed rock Cudahy Park Renovation Project, Project # PRE-001 Document Control 133 of 1214 Page 163 of 1692 Updated Draft Geotechnical Investigation Report

9 sandwiched by layers of filter fabric, MiraFi 140 or equivalent.

Following the over-excavation, the areas to receive engineered fill shall be sacrificed to a minimum depth of 8 inches, moisture-conditioned within optimum and 2 percent above optimum moisture content and compacted to at least 90% of the maximum dry density obtained per ASTM D1557.

The excavated zone then shall be backfilled with engineered fill. Unless stated otherwise, all fill materials should be placed in loose lifts of 8 inches or less, moisture-conditioned within optimum and 2 percent above optimum moisture content and compacted to at least 90% relative compaction of the maximum density as determined by the ASTM D1557. Compaction should be verified by observation, probing, and testing by a geotechnical consultant’s representative.

7.2.2 Fill Materials
The on-site soils may be reused for backfilling purposes if the soils conform to the materials and gradation requirements for fill materials stated in this section. Note that soil cuttings retrieved during our field investigation are classified as CA Hazardous for Lead as noted in Section 5.2.

Imported soils are anticipated to be used in the required compacted fills and backfills. Imported materials should contain sufficient fines (binder material) to be relatively impermeable and result in a stable subgrade when compacted. The imported materials should also be non-expansive, with an Expansion Index of less than 30 and free of organic materials, debris, and cobbles larger than 3 inches, with no more than 25 percent of materials being larger than 2 inches in size and no more than 25 percent passing #200 sieve. A bulk sample of potential import material, weighing at least 30 pounds, should be submitted to the Geotechnical Consultant at least 48 hours before fill operations. The Geotechnical Consultant should approve all proposed import materials before being placed at the site.

7.2.3 Temporary Excavation
Temporary unsurcharged excavations must be adequately sloped or shored. Based on the earth materials encountered in our borings, excavation of 4 feet or less in depth may be performed with vertical sidewalls unless granular (cohesionless) soils are encountered. Deeper excavation can be accomplished per the Occupational Safety and Health Administration (OSHA) requirements, and it shall be laid back at a 1H:1V gradient or flatter.

Excavations adjacent to any existing footing should be performed in a slot cut, not completely removing the lateral support, under close observation of the geotechnical engineer’s representative.

The contractor is responsible for maintaining the stability of the cuts and personnel safety in the field during construction. All excavations shall be performed per applicable requirements established by the State, County, or local government. The regulatory requirement may supersede the recommendations presented in this section. The Geotechnical Engineer of Record’s representative should be present during all excavations.

7.4 FOUNDATION DESIGN

7.4.1 General
From geotechnical perspectives, the courts, skate park and playground may be supported by concrete slab-on-grade given that the recommended over-excavation and compaction with imported fill as noted in Section 7.2.1 is adopted, if needed.

The following proposed features are recommended to be supported by a composite foundation scheme consisted of a ground modification measure with vibro stone columns (VSCs) installed from the bottom of Geosynthetics-Reinforced Load Transfer Platform (GRLTP) layer that is five (5) feet in depth, to thirty-six (36) feet bgs and a GRLTP layer constructed over VSCs within the upper five (5) feet.

11 • Shade canopies, and
• Field lightning.

7.4.2 Shallow Foundation on GRLTP
As noted in Sections 6.3 and 7.1, proposed storage building, and other improvements need to be founded by shallow foundations supported by a combination of VSCs and GRLTP due to the liquefaction-induced settlement.

The shallow square footings supported by GRLTP should be at least 24 inches wide and embedded at least 24 inches into the approved compacted soils. The foundations supported on GRLTP may be designed for an allowable pressure of 1,500 psf due to dead plus live loads. The bearing capacity may be increased by one-third for transient loads such as seismic or wind. Foundation design details such as concrete strength, reinforcements, etc. should be established by the Project Structural Engineer.

Footings adjacent to utility trenches or other footings should be deepened as necessary so that their bearing surfaces are below an imaginary plane with an inclination of 1H:1V, extending upward from the bottom edge of the adjacent trench or footing.

Resistance to Lateral Loads: Lateral soil resistance will be provided by a combination of frictional resistance between the bottom of the footings and the underlying soils and by passive soil resistance acting against the side of the footing. For site preparation implemented as per recommended in the pertinent sub-sections of Section 7.2, an ultimate frictional coefficient of 0.35 between concrete and soil may be used. For passive resistance, an equivalent fluid pressure of 250 pcf may be used for a level ground surface condition in front of the footing, subject to a maximum of 2,000 pcf. Note that the design of most shallow foundations conservatively ignores passive resistance per FHWA-SA-02-054 Geotechnical Engineering Circular No 6 Shallow Foundations (2002). When combining both frictional and passive resistance, the passive resistance should be reduced by one-third. The recommended value for passive resistance may be increased by onethird for short-term loading.

Note that the analysis and recommendation for a deep foundation system, such as driven concrete piles would require additional exploratory borings extended to greater depths where nonliquefiable competent soils are encountered, on which the deep foundation would have to extend to and gain bearing support from, as liquefaction-prone soils have been identify to a maximum depth of 50 feet below the existing ground surface. The Project Geotechnical Engineer should be engaged for additional investigation if the Client would like to explore further on the deep foundation.

Settlement: The total static settlements due to structural loads will are assessed once the design structural loads for the proposed features are provided to us by the Design Team.

12 7.5 CONCRETE SLAB-ON-GRADE

7.5.1 General
Concrete slab-on-grade may be constructed on compacted fill prepared per recommendations provided in Section 7.2. The slab-on-grade should be at least 5 inches thick and reinforced with a minimum No. 3 rebar at 18 inches on center. Concrete slab-on-grade may be designed using a maximum bearing pressure of 1,000 psf.

7.5.2 Moisture-Sensitive Floor Covering
An impermeable membrane (vapor barrier) should be installed below the concrete in contact with soil to reduce excess vapor drive through the slab. The membrane should be at least 10-mil thick, and care should be taken to preserve the continuity and integrity of the membrane beneath the floor slab. At least 4 inches of free drainage gravel, with no more than 2 percent passing No. 200 sieve, should be placed below the vapor barrier to serve as a capillary break. The gravel layer shall be compacted to a minimum of 92% relative compaction per ASTM D1557. The gradation for the free drainage material used shall conform to the No. 3 Concrete Aggregates requirements as specified in section 200-1.4 of the latest edition of Greenbook.

Another factor affecting vapor transmission through floor slabs is the water-to-cement ratio in the concrete used for the floor slab. The water-to-cement ratio increases the porosity of the concrete, thereby facilitating the transmission of water vapor through the slab. The Project Structural Engineer should provide recommendations for concrete design for footings and concrete slab-ongrade per the latest version of the applicable codes.

7.6 SOIL CORROSIVITY
Two representative bulk samples obtained from the borings drilled within the subject project site were tested for pH, minimum resistivity, soluble chloride content, and soluble sulfate content per Caltrans CTs 417, and 422 and 643. The measured resistivity, soluble chloride, and pH value indicate that onsite soils can be classified as non-corrosive to structural elements. A further interpretation of the corrosivity test results and providing corrosion design and construction recommendations are referred to corrosion specialists, if necessary.

7.7 EXPANSION POTENTIAL
Two representative bulk samples obtained from the borings drilled within the subject project site were tested for expansion potential per ASTM D4928. The measured Expansion Index (EI) of 3 and 6 suggests that onsite soils are of low expansion potential.

7.8 INFILTRATION TESTING
The average infiltration rate for the soils within the upper 5 feet of the subsurface was measured by falling head percolation test conducted at Boring P-1. Boring location is shown in Figure 1.

The percolation test for the subject Project site was performed in accordance with the County of Cudahy Park Renovation Project, Project # PRE-001 Document Control 137 of 1214 Page 167 of 1692 Updated Draft Geotechnical Investigation Report

During the field investigation, the 8-inch diameter boring was lined with 3-inch diameter perforated PVC pipes surrounded by gravel filter packs. The hole was presoaked to provide an equilibrium condition prior to recording the time and drop in water level. The water level was monitored for about 20 minutes, with measurements taken every twenty (20) minutes. The test data and calculations are attached to this report. The measured infiltration rates were reduced using the reduction factors addressed in LID manual (GS200.2, 2017) to determine the design values.

The infiltration test results are provided in Table 3. Calculation of Infiltration test is shown in Appendix D.

The design infiltration rate calculated was found to be less than the minimum required rate of 0.3 in/hr as addressed in LID manual. Based on the test results, the measured infiltration rate at the test location P-1 does not warrant the sufficient amount of water flow infiltration through the existing soil layers.

Converse Project No. 24-41-114-01
Mr. Peter:

Converse Consultants (Converse) appreciates this opportunity to present our Soil Sampling Workplan for supplemental soil sampling activities to be completed at Cudahy Park. Our Workplan is based upon our Proposal dated March 29, 2024.

PROJECT DESCRIPTION AND BACKGROUND
The Cudahy Park Renovation Project focuses on parkwide renovation improvements such as renovating basketball, baseball, tennis courts, as well as the playground and skate park. Additions to the park include a community stage, splash pad, exercise equipment, picnic area, and shade structures. During the course of a geotechnical investigation completed as part of the renovation project, three (3) geotechnical borings (B-1, B-2, and P-1) were advanced at locations across the project area. Borings B-1 and B-2 were advanced to depths of 20-feet below ground surface (bgs) while boring P-1 was advanced to a depth of 5-feet bgs.

Converse has reviewed the analytical results of the composite soil samples collected from soil cuttings generated during the geotechnical investigation. The data indicates that the reported concentration of total lead in waste profile sample #2 (associated with boring B2, located near the baseball fields) exceed screening levels for residential and commercial uses, and therefore should ideally be removed from this park site where children could be exposed to it. The soluble levels of lead in this sample would result in the soil from that location needing to be classified as non-RCRA California Hazardous Waste for handling and disposal purposes.

The results for the other samples analyzed indicate that soils from those areas are less than screening level concentrations and should therefore be acceptable for reuse onsite.

SCOPE OF WORK
Task 1 – Pre-field Activities
An initial site visit to inspect the site and conduct a required USA (Dig Alert) mark-out will be conducted. Converse will notify Underground Service Alert 72 hours prior to conducting sampling activities.

A boring permit was obtained from the County of Los Angeles Department of Public Health, Environmental Health Protection Division, Drinking Water Program (See Appendix A).

Additionally, Converse has prepared a site-specific Health & Safety Plan (See Appendix B).

Task 2 – Soil Sampling
Proposed field activities include the advancement of up to eight (8) borings. Seven (7) borings are proposed to be advanced to maximum depths of 8-feet bgs. One (1) boring, in the vicinity of geotechnical boring B-2, is proposed to be advanced to a depth of 20- feet bgs. Proposed boring locations are presented on Figure 1.

Soil borings are to be advanced using direct-push drilling methods. Soil samples are proposed to be collected from each boring at depths of 1, 2, 4, 6, and 8-feet bgs, with additional samples collected from the deeper 20-foot boring at depths of 12, 16, and 20- feet bgs.

Dry decontamination of drilling and sampling equipment will be conducted between boring locations (e.g. Simple Green and paper towel wipe down). Shallow boreholes may be backfilled with commercially available sand, or hydrated bentonite. The deep boring will be backfilled with cement slurry grout, placed using a tremie pipe, in accordance with the requirements of the terms of the permit. Soil conditions will be documented utilizing a boring log format.

All excess soils generated from the drilling and sample collection activities will be contained in a 55-gallon drum. A composite sample will be collected from the drum to generate a waste profile sample. The drum will be temporarily stored onsite until the results of the profile sample are received. The drum will be picked up later and transported to an appropriate facility for disposal.

Task 3 – Laboratory Analysis

Soil samples will be submitted to an ELAP-accredited laboratory for analysis. Initially, soil samples collected from depths of 1.0 and 2.0-feet bgs from each of the eight (8) borings (16 total samples) will be analyzed on a standard turnaround time (7-10 business Cudahy Park Renovation Project, Project # PRE-001 Document Control 192 of 1214 Page 222 of 1692 Willdan

days) in accordance with Environmental Protection Agency (EPA) Test Method 6010 for Total Threshold Limit Concentration (TTLC) lead. All remaining samples will be archived pending the results of the initial samples analyses.

The composite sample collected from the drum will be analyzed for constituents necessary to develop a waste profile. It is anticipated that this sample will be analyzed for metals, VOCs, and hydrocarbons in accordance with EPA Methods 6010/7471, 8260B, and 8015M, respectively.

Task 4 – Reporting
A summary report will be prepared following completion of field activities and receipt of analytical results. Included in the report will be a summary of the fieldwork and methodologies, as well as a discussion and summary of the analytical results. Converse will also present our conclusions and recommendations, if any. Copies of summary tables of sample analytical results, and laboratory analytical reports with chain of custody documentation will be provided in the report. The report will be signed by a California Professional Geologist (PG).

SCHEDULE
The soil sampling is estimated to be completed in one (1) day, and it can commence approximately three (3) days after the site is marked for USA utility clearance.

Laboratory analyses will be conducted on a standard 7 to 10 business day turnaround.

The draft summary report will be presented within two (2) weeks following the receipt of final analytical results.

IV. Decontamination/Hazardous Waste Generation
A) Sampling Equipment Decontamination
All soil samples will be collected using new acetate sleeves, therefore cross contamination is not a significant concern. Samples will be collected with disposable nitrile gloves and any reusable equipment will be decontaminated prior to collection of subsequent samples.

B) Personal Protective Equipment (PPE)
- Nitrile gloves when handling samples or sampling equipment - Hardhat
- Safety Vest
- Steel-toed boots
- Safety Glasses
C) Heavy Equipment
- Geoprobe drill rig
- Drill rig trailer and/or support truck
D) Hazardous Waste Generation
1) Based on the results of prior assessment activities at the Site, it is anticipated that soil cuttings from the drilling activities may contain soluble lead concentrations that would exceed hazardous waste thresholds. Therefor, all excess soils will be contained in a 55-gallon drum, and a waste profile sample will be collected to determine if the soils need to be handled and disposed of as a hazardous waste.

1.0 Introduction
The purpose of this Soil Management Plan (SMP) is to provide procedures and protocols to be utilized if contaminated soil is encountered during any construction excavation activities for the proposed Cudahy Park Renovation Project at 5220 Santa Ana Street, in the City of Cudahy, Los Angeles County, California (Site) (Figure 1).

2.0 Site Background
In January 2015, the City of Cudahy and State of California Department of Toxic Substances Control (DTSC) signed a Covenant to Restrict Use of Property (Covenant), Environmental Restriction, County of Los Angeles, Assessor Parcel Number 6224-014- 905. Pursuant to Civil Code Section 1471, the DTSC determined that the Covenant was reasonably necessary to protect present or future human health or safety or the environment as a result of the presence on the land of hazardous materials as defined in Health and Safety Code Section 25260. Pursuant to Civil Code Section 1471, and Health and Safety Code Section 25355.5, the City of Cudahy and DTSC agreed that the use of the Site be restricted as set forth in the Covenant.

As indicated in the Covenant, the Site is located in the area now generally bounded by Park Avenue Elementary School to the north, River Road to the east, and residences to the south and west. The Covenant covers two (2) specific areas of the Site, identified as the “Tree Boundary Area” and “River Road Area”. These areas are indicated on Figure 2 – Covenant Area. The Tree Boundary Area is located in the area now generally bounded by the basketball court and parking lot on the north, River Road on the east, and baseball fields on the south and west. The River Road Area is located at the eastern part of Los Angeles County Assessor’s Parcel No. 6224-014-905.

According to the Covenant, the Site was remediated pursuant to a Removal Action Workplan (RAW) developed under Chapter 6.8 of division 20 of the Health and Safety Code, under the oversight of DTSC. The RAW provided that a deed restriction be required as part of the site remediation, because lead, benzo(a)pyrene, toluene, and xylenes, remain at depths of one-foot or more below the surface of the Tree Boundary Area and River Road Area. Following approval of the RAW, soils were excavated to depths of 8 to 14 feet below ground surface (bgs), graded, and then backfilled with clean soil. As detailed in the Final Removal Action Completion Report that was approved by DTSC on December 8, 2005, a portion of the subsurface soils within 10 feet of the surface of the Tree Boundary Area contain hazardous substances including lead (1,103 parts per Cudahy Park Renovation Project, Project # PRE-001 Document Control 216 of 1214 Page 246 of 1692 Willdan

million [ppm]), benzo(a)pyrene (4.18 ppm), benzene (1.3 ppm), toluene (2.3 ppm), and xylenes (2.9 ppm). The soils underneath the River Road Area within 10 feet of the surface contain lead (2,160 ppm), and benzo(a)pyrene (2.71 ppm). The DTSC further concluded that the remainder of the Site, as remediated, does not present an unacceptable threat to human safety or the environment.

Section 4.02 of Article IV of the Covenant provided the following restrictions pertaining to Soil Management:
a) No activities that will disturb the soil (e.g. excavation, grading, removal, trenching, filling, earth movement or mining) shall be allowed on the Tree Boundary Area or under River Road without a Soil Management Plan and Health and Safety Plan approved by the DTSC.
b) Any contaminated soils brought to the surface by grading, excavation, trenching, or backfilling shall be managed in accordance with all applicable provisions of state and federal law.
c) The Owner shall provide the DTSC written notice at least 14 days prior to any building, filling, grading, mining, or excavating in the Tree Boundary Area or under River Road.

Project Description
The Cudahy Park Renovation Project focuses on parkwide renovation improvements such as renovating basketball, baseball, tennis courts, as well as the playground and skate park. Additions to the park include a community stage, splash pad, exercise equipment, picnic area, and shade structures.

As part of the renovation activities, both demolition and construction activities are proposed in the area(s) covered under the Covenant.

Tree Boundary Area
Demolition activities proposed in the Tree Boundary Area will include the removal of two (2) existing concrete pads with park table, trash receptacle, and barbeque grill; removal of an existing park light; and removal of two (2) existing trees (including roots to 36-inches in depth).

Construction activities proposed in the Tree Boundary Area include the installation of a 4-inch thick Portland concrete cement (PCC) walkway/paving with retardant slab and pad, and installation of a pre-fabricated amphitheater/shade structure.

River Road Area
Demolition activities proposed in the River Road Area include the disassembling and removal of the existing baseball bleachers, baseball benches, and backstop.

Construction activities proposed in the River Road Area include the assembly and installation of prefabricated bleachers, benches, and backstop.

Proposed development plans are presented in Appendix A, with shading indicating the approximate extents of the Tree Boundary and River Road Areas.

Based on the proposed renovation activities potentially encountering contaminated soils in the areas covered by the Covenant, and in accordance with Section 4.2c of Article IV of the Covenant, this SMP should be submitted and approved by DTSC prior to commencing renovation activities in these areas.

3.0 Site Conditions
The following information was obtained from the Willdan Engineering Draft Geotechnical Investigation Report, Cudahy Park Renovations, Cudahy, California, dated December 21, 2023.

3.1 Subsurface Profile of Project Site
Site Geology and Hydrogeology
The Site is in Cudahy along the western side of the north-south trending Los Angeles River (LAR) channel about 13 miles north of the Pacific Ocean. The topography in the study area slopes gently southward, generally parallel to the LAR channel.

The low land surface slopes gently south or seaward, interrupted by the Coyote Hills near the northeast margin, a line of elongated low hills to the south and west that extend from Newport Bay northwest to Beverly Hills, and by the Palos Verdes peninsula along the southwestern extremity.

Soils encountered to maximum depths of 21.5 feet bgs during the geotechnical investigation consisted primarily of fill and brown silty to clayey sand and sandy to silty clay.

Review of the CDMG Seismic Hazard Zone Report for the project area (CDMG, 1998, South Gate Quadrangle), indicates that historically high groundwater in the vicinity of the project site may have been within 8 feet of ground surface. The project area is in a liquefaction hazard zone as mapped by the CGS.

Groundwater was not encountered during the geotechnical investigation.

3.2 Subsurface Variations
Based on results of the subsurface exploration by others and our experience, some variations in the continuity and nature of subsurface conditions within the project site should be anticipated. Because of the uncertainties involved in the nature and depositional characteristics of the earth material at the Site, care should be exercised in interpolating or extrapolating subsurface conditions between or beyond the boring locations. If, during construction, subsurface conditions differ significantly from those presented in this SMP, the Owner should be notified immediately so that recommendations can be modified, if necessary.

4.0 General Information
Converse recommends that the Owner and the Contractor and subcontractors consider the following recommendations prior to and during all soil excavation activities.

4.1 Construction Equipment’s Maintenance Area
It is recommended that construction equipment maintenance and storage areas be protected with the installation of an impermeable layer made of geomembrane and one (1) to two (2)-inch diameter crushed rock to collect oil and hydraulic drips. All equipment should be fueled over the protective layer made of fabric and rock.

4.2 Dust Control and Monitoring
It is assumed that truck and vehicle staging will be onsite. Traffic patterns and startup can affect the number of vehicles in staging. Shaker plates should be installed at the construction entrance and/or exit. The purpose of these plates is to slow down the truck traffic and to provide dust control by removing dirt from the treads of the truck tires.

Water trucks or buffaloes should be present at all times at the Site. The water trucks should be used for dust control and other construction activities that require water.

Contractor should apply the necessary water to prevent dust emissions. These operations should be closely monitored by the Project Manager and/or Superintendent.

South Coast Air Quality Management District (SCAQMD) has three (3) rules which address excavation work (Rules 1150, 1166 and 1466), and one (1), which addresses fugitive dust (Rule 403). Rule 1150 applies to the excavation of sanitary landfills and does not apply to this project.

Rule 1166 applies to the excavation of soils containing VOCs and may apply to this project based on the reported concentrations of VOCs in soils including benzene, toluene, and xylenes. Several elements of Rule 403, including air monitoring protocols and mitigation of potential fugitive dust emissions should be incorporated into the project as may be required by the SCAQMD. Protocols outlined in Rule 1466 for Toxic Air Contaminants will apply should the volume of soil to be disturbed at depths greater than 1.0-foot bgs in the Covenant-covered areas exceed 50 cubic yards. Copies of the Rules are presented Appendix B.

Air monitoring should be performed during all Site activities in which impacted or potentially contaminated materials are being disturbed or handled. Details regarding air monitoring and potential sampling procedures are presented in the Health and Safety Plan (HASP) in Appendix C. The contractor will staff the Site with an air monitoring/health and safety professional whose responsibilities will include:
• Monitoring dust levels in the exclusion zone and other locations. The Site air monitoring professional will have the authority to stop-work in the event that onsite activities generate dust levels that exceed the Site or community action levels (see the chart below). The air monitoring professional will monitor onsite meteorological instrumentation and/or coordinate with offsite meteorological professionals to identify conditions that require cessation of work, e.g., winds in excess of 15 mph. In accordance with SACQMD Rule 1466, the action levels for work stoppage will be set at a sustained wind velocity of 15 mph averaged over a 15-minute period, or instantaneous wind speeds exceeding 25 mph.
• Assure that all real-time aerosol monitors and industrial hygiene air sampling equipment and media are properly calibrated and in good working condition.

Real-time, data-logging aerosol monitors (personal data ram) will be used, when required, to measure dust levels. Real-time information will be posted daily and discussed with Site workers. As potential analytical results for industrial hygiene samples (using OSHA/ National Institute of Occupational Safety and Health (NIOSH) approved methods, such as NIOSH 7082 and 7105 for lead dust scan) are received, the air monitoring professional will prepare summary sheets and discuss results with onsite management and workers.
• Coordinate general Site safety activities including all daily hazard communication, safety practices and procedure briefings. • Oversight of personal decontamination practices.
• General Site safety leadership, support and recordkeeping activities.

4.3 Traffic Control and Road Maintenance
Contractor shall provide and maintain all traffic control devices in accordance with local authorities and The California Department of Transportation Manual of Traffic Controls for Construction and Maintenance Work Zones, including but not limited to Cudahy Park Renovation Project, Project # PRE-001 Document Control 221 of 1214 Page 251 of 1692 Willdan

flagmen, signs, lights, barricades and all other equipment needed to insure the safety of vehicular and pedestrian traffic.

Street cleaning equipment (sweepers) should be provided when appropriate, especially during hauling days. The cleaning equipment should prevent migration of loose dirt and water to catch basins and reduce the migration of dust to the neighboring sites.

4.4 Construction Worker Health and Safety Plan
All contractors will be responsible for operating in accordance with the most current requirements of Title 8, California Code of Regulations, section 5192 (8 CCR 5192) and Title 29, Code of Federal Regulations, section 1910.120 (29 CFR 1910.120), Standards for Hazardous Waste Operations and Emergency Response (HAZWOPER). Onsite personnel are responsible for operating in accordance with all applicable regulations of the Occupational Safety and Health Administration (OSHA) outlined in 8 CCR General Industry and Construction Safety Orders and 29 CFR 1910 and 29 CFR 1926, Construction Industry Standards, as well as other applicable federal, state and local laws and regulations. All personnel shall operate in compliance with all California OSHA requirements.

A Health and Safety Plan (HASP) for the SMP has been prepared and is provided in Appendix C. The provisions of the HASP are mandatory for all personnel of the PP and its contractors who are at the Site. The PP’s contractor and its subcontractors doing fieldwork in association with this SMP will either adopt and abide by the HASP or shall develop their own safety plans which, at a minimum, meet the requirements of the HASP. All onsite personnel shall read the HASP and sign the “Plan Acceptance Form” (Attachment A of the HASP) before starting Site activities.

4.5 Construction Site Access and Control
Access to the Site during construction and maintenance activities will be limited to authorized personnel in compliance with HASP requirements. The potential for trespassers or visitors to gain access to construction areas and come into direct contact with potentially contaminated soil will be controlled through the implementation of the following access and perimeter security measures:

• Security fencing will be placed around any portion of the Site that is under construction or where potentially contaminated soil is exposed to prevent pedestrian/vehicular entry except at controlled (gated) points. • Gates will be closed and locked during non-construction hours. Fencing will consist of a chain link or equivalent fence unless particular safety considerations warrant the use of a higher fence.
• Post “No Trespassing” signs every 200 feet.
• Post proposition 65 signs warning that contamination within the fenced areas may be harmful to health.

Implementation of appropriate Site-specific measures as outlined above will reduce the potential for trespassers or visitors to gain access to construction areas and to come into direct contact with potentially contaminated soil or groundwater.

4.6 Dust Emissions
Dust emissions are regulated under SCAQMD Rule 403 Fugitive Dust and Rule 1466 Control of Particulate Emissions from Soils with Toxic Air Contaminants. The purpose of these Rules is to reduce the amount of particulate matter entrained in the ambient air as a result of anthropogenic (man-made) fugitive dust sources by requiring actions to prevent, reduce or mitigate fugitive dust emissions. Work shall be in compliance with Rule 403. As indicated in Section 4.2, work will also need to be performed in accordance with protocols of Rule 1466 should soil disturbance in the Covenant-covered areas exceed 50 cubic yards. A copy of these Rules are presented in Appendix B.

5.0 General Management Procedures for Excavated
Soil
It is possible to contaminated soil remaining onsite in previously identified areas may be encountered during project activities. It is our recommendation that the initial excavation activities be monitored on a continual basis using visual and olfactory observations.

Figure 3 provides a generalized flowchart of the soil excavation monitoring process. The figure presents the steps to be followed during excavations with the purpose to check if the excavated soils may be reused onsite or if they must be removed from the Site.

5.1 Visual and Olfactory
As described in Section 2, above, the potential exists for encountering soil potentially contaminated with VOCs and potentially other hazardous substances.

As a result of this condition, it will be important to segregate and manage contaminated soil separately from clean soil during excavation, transport, and offsite disposal activities.

To facilitate such segregation, the excavation contractor will work with a qualified environmental geologist (PG) or engineer (PE), experienced in the identification and screening of potentially contaminated soil, to assist in drawing the distinction between clean and contaminated soil. Field screening may be conducted using multiple tools consisting of observing visual and olfactory characteristics and monitoring organic vapor emissions using organic vapor monitoring instruments such as a photoionization detector (PID), organic vapor monitor (OVM), or organic vapor analyzer (OVA).

Throughout the course of excavation, the environmental professional will observe the material being excavated and provide guidance on the material classification based on initial visual and olfactory characteristics. Visual evidence of contaminated soil will include soil coloration that is distinctly different than the native soil (discoloration), evidence of an oily or waxy sheen, presence of liquid or free-phase solution that is not groundwater, or other atypical non-native characteristic. Olfactory evidence of contaminated soil will include chemical odors, rotten egg odors, and/or petroleum odors (gasoline, diesel fuel, or crude oil type odors). Soil that shows visual and/or olfactory characteristics of contamination will be screened with a PID or similar organic vapor monitoring instrument. Soil that has been determined to be potentially contaminated on the basis of visual, Cudahy Park Renovation Project, Project # PRE-001 Document Control 224 of 1214 Page 254 of 1692 Willdan
Cudahy Park Renovation Project

5220 Santa Ana Street, Cudahy, California
February 27, 2025
CONVERSE Project No. 24-41-114-02 10
Copyright 2025 CONVERSE CONSULTANTS
olfactory, and organic vapor readings will be segregated and managed in accordance with the protocol described in Section 5.4.

We recommend that visual and olfactory observations be conducted at all times.

The screening will help to minimize the mixing of clean and potentially contaminated soil in the excavation or trucks. Non-contaminated native soils typically have a distinct color and bedding as well as other physical attributes.

Chemically-impacted soils can exhibit a coloration that is distinctly different from surrounding non-contaminated soil materials.

When soils exhibit suspect color or odor, it is recommended that they not be excavated (left in situ) and be sampled in accordance with the procedures described below. Exposed or disturbed soils that exhibit suspect color or odor should be covered with 10-mil plastic sheeting pending analytical results.

In the event that suspect asbestos containing materials (ACM) are observed during excavation procedures, the excavation of that area will be stopped, and the area demarcated. The suspect ACM will be sampled by a Certified Asbestos Consultant and analyzed by a state-certified laboratory for asbestos content on a rush basis.

Soils in contact or associated with the suspect ACM will be segregated pending analysis. The analytical procedure for asbestos analysis will be South Coast Air Quality Management District (SCAQMD) Rule 1403. Any further action will be in accordance with Rule 1403 but not limited to Procedure 5 Work Plans for asbestos transite pipes as applicable. A copy of rule1403 is provided in Appendix C.

5.2 PID Screening
Should visual and olfactory observations indicate the presence of suspected contamination, screening should be conducted with a photoionization device (PID) or similar device. PID screening is a semi-quantitative method for evaluating whether excavated soil is potentially contaminated. A PID can detect volatile organic compounds (VOCs) such as some petroleum hydrocarbons and solvents, which are common industrial pollutants. Should VOCs be encountered during excavation activities, field monitoring with a PID should be conducted along with visual and olfactory observations to identify suspect and contaminated soil.

Soil screening should be conducted at regular intervals (15 minutes) during all excavation activities with a properly calibrated PID and logged. The calibration of the PID shall be checked every day with hexane as the calibration medium (span gas).

CONVERSE Project No. 24-41-114-02 11
Copyright 2025 CONVERSE CONSULTANTS
The South Coast Air Quality Management District (SCAQMD) has established guidelines for the excavation of VOC-impacted soil. These guidelines are published in SCAQMD Rule 1166. Rule 1166 is applicable to any site where excavation activities have the potential to encounter VOC-impacted soils. If VOCs in excess of 50 parts per million (ppm), as measured with the PID calibrated to hexane, are encountered during excavation, the work must proceed under Rule 1166 guidelines, including notifications and permits.

The contractor shall apply for and obtain an approved mitigation plan prior to commencement of excavation or soil handling activities of VOC-impacted soils.

All PID measurements should be performed by placing the PID probe inlet no more than 3 inches from the surface of the excavated soil. If a reading greater than 50 ppm is initially noted at a particular location, the area should be re-screened at several locations to establish a consistent assessment of VOC levels. If PID readings are consistently above 50 ppm, Rule 1166 requirements must be implemented. The general requirements of Rule 1166 that affect excavation activities are summarized below:
− Contractor shall notify the Owner and the local SCAQMD within 24 hours that soils were found with PID readings greater than 50 ppm (SCAQMD’s Office is located in Diamond Bar, Los Angeles County, California and SCAQMD’s Phone Number is 909-396-2000).
− Implement approved mitigation plan.
− The total quantity of VOC-contaminated soil excavated should not exceed 2,000 cubic yards without taking further action. In the event that more than 2,000 cubic yards of VOC-contaminated soil is encountered, then a site-specific SMP for VOC-Contaminated soil must be prepared and submitted to the SCAQMD for approval before further excavation of VOC-contaminated soil may take place.
− During excavation, Contractor should take all precautionary measures to minimize the release of VOCs, odors, and dust, including but not limited to:
• Use of additional plastic sheeting and sandbags,
• Use of suppressants on exposed soil surfaces, and
• Maintaining paved public streets free of soil deposits.

− All VOC-contaminated soil below 1,000 ppm, as measured by PID, should be stockpiled/containerized. If stockpiled, the soil shall be placed on and covered with plastic sheeting, and stored separately from non-VOC-contaminated soil. − A VOC-contaminated stockpile (if applicable) should not contain more than 400 cubic yards of soil.
− Only the working face of the stockpile (if applicable) is exposed during excavation and all other portions of the stockpile be covered with plastic sheeting.
− All VOC-contaminated soil should be removed from the Site within 30 days of its excavation.

A copy of SCAQMD Rule 1166 is provided in Appendix B.

5.3 Sampling and Analysis Procedures
Any soil proposed to be removed from the Site, whether suspected to be clean or impacted, should initially be sampled in general accordance with the State of California Department of Toxic Substances Control (DTSC) Information Advisory for Clean Imported Fill, Appendix D. Soil samples may be collected from the bucket of the excavator, or directly from the sidewalls of the excavation areas. The samples will be collected directly into laboratory supplied glass jars and PreCore or Encore sample containers. In the event that excavated soils are stockpiled onsite, discrete samples will be collected from varying locations and depths at the stockpile. Soil for the analyses will be collected in laboratory-supplied 4 oz. glass jars. Sub-samples for VOC analysis will be collected from the stockpile in accordance with EPA Method 5035 using Pre-core or Encore sample containers.

In addition, a portion of the soil samples from each location will be collected into sealable plastic bags and screened in the field for the presence of VOCs using a PID.

All sample containers will be labeled and placed in an ice-chilled cooler for transport to a State of California Certified Environmental Laboratory for analysis on a rapid turnaround time (TAT) basis (24-hour TAT or earliest possible) in accordance with the following analytical methods or any deemed necessary by the PG or PE. • 6010/7471 – Title 22 Metals

• 8260B – Volatile Organic Compounds (VOCs)
• 8270 – Polycyclic Aromatic Hydrocarbons (PAHs)
Based on the results of the laboratory test analyses and using Figure 3, the soil material should be characterized and if required, additional laboratory tests should be performed. Figure 3 will lead to one of the following alternatives:
• The soil is cleared for reuse onsite or off-site as clean fill; • The soil should be disposed of off-site at an appropriate facility, or • Additional sampling and analysis should be conducted to properly characterize the soil for waste disposal.

5.4. Stockpile Management
Stockpiling of excavated and/or imported soils may be necessary on a temporary basis to support the logistical phasing of the redevelopment activities. Whenever possible, soil stockpiles will be located in close proximity to the work area or the ultimate disposition area as practicable within the Site. Soil that has been determined to be potentially contaminated, on the basis of field screening, will be stockpiled separately from clean soil.

Stockpiles will be managed in compliance with storm water runoff and dust control requirements. Storm water runoff requirements will be specified in a project-specific Storm Water Pollution Prevention Plan (SWPPP). In general, stockpiles must be covered with a tarp, wetted, sloped, or controlled via appropriate means and methods as specified in the SWPPP and Dust Control Plan (DCP). Best management practices (BMPs) for erosion and sediment control will be implemented, as specified in the SWPPP, during construction activities. BMPs may include diversion of drainage from the stockpiles, installation of silt fencing/straw bale filter barriers on the down gradient toe of the stockpile slope, and dust control.

Stockpiles will be under control of the General Contractor at all times and inspected at least weekly to ensure dust control and runoff control measures are functioning adequately and as specified in the appropriate plans.

5.5 Soil Import Criteria
All soil imported onto the Site will be subject to sampling and soil quality controls established in the DTSC’s October 2001 Clean Imported Fill Material Information Cudahy Park Renovation Project, Project # PRE-001 Document Control 228 of 1214 Page 258 of 1692 Willdan

Advisory or other appropriate regulatory guidance. A copy of the Advisory is included in Appendix D. When the chemical properties of imported fill are known sampling may not be required. Soil quality parameters for acceptable imported soil are based on the most applicable of the U.S. EPA Regional Screening Levels (RSLs) for residential land use or background concentrations for metals in soil.

Import soil with visual or olfactory evidence of petroleum hydrocarbons or other chemical contamination is prohibited. The soil import criteria do not address the vapor intrusion to indoor air pathway, and further screening for vapor intrusion concerns may be required if volatile chemicals are detected in imported soil. Import of soil with any level of VOCs is prohibited.

5.6 Reporting
Daily field notes of the monitoring activities will be provided at the end of each day.

Field notes will include at a minimum, the areas of excavation completed that day, final excavation depths at the end of the day, PID readings for the day and the analytical report from the previous day’s sampling. See Appendix E for the Soil Screening Form.

6.0 Unanticipated Conditions
The potential exists for encountering unknown conditions during the course of development. Unknown conditions are physical or chemical conditions that have not been previously identified and evaluated as documented in the Site investigation activities, summarized in Section 2. Unknown conditions may include unanticipated soil and/or soil vapor contamination, unexpected subsurface structures, buried pipelines, USTs, and/or other visual or olfactory evidence of contamination. This section establishes a protocol for the initial response to the discovery of an unknown condition, notification protocols, and a path forward such that development activities can continue safely. The Site-specific health and safety training that project proponents are required to provide to Site workers will include instruction on how to identify potential unknown conditions.

The primary purpose of the protocols presented in this Section are to: i) provide initial required response and notification of the discovered condition, ii) prescribe the collection and analysis of initial samples; and iii) provide the Owner and appropriate agencies with initial sampling data, documentation of proposed further work, and results of response actions, when complete.

CONVERSE Project No. 24-41-114-02 15
Copyright 2025 CONVERSE CONSULTANTS
The specific sampling to be conducted will be dependent on the nature of the discovered condition, chemicals of concern (COCs) and potential impacts, and regulatory requirements. In the event that unanticipated contaminated soils are suspected to have been encountered during earthwork activities (based on odors, staining, or other potential observations), it is recommended that the earthwork activities in that area be immediately ceased, the area be quarantined, and notification provided to the Owner and/or their authorized representative for further direction. It is recommended that the Contractor and/or Field Inspector document in writing with field sketches and demarcate the locations of the potentially contaminated soil. Exposed potentially contaminated soils should be covered with 10 mil thick plastic sheeting. The Project’s Environmental Consultant should immediately conduct field screening and collect soil samples for laboratory analysis.

If contamination is confirmed by laboratory analysis, appropriate protocols should be followed in general accordance with regulatory guidance. Consequently, further soil excavation should be performed by a contractor with a valid California State Contractors Board Hazardous Substance Removal Certification (HSRC) and under appropriate health and safety measures. It is recommended that excavation of any impacted soil be performed as soon as possible to continue with the construction logistics and timing of the project. The excavations should be monitored by a representative of the Owner and/or a third-party environmental consultant. Figure 3 illustrates a step-by-step flow chart that identifies soil management activities and key decision points when soil is found to be contaminated.

6.1 Notification
Upon discovery of a non-emergency unanticipated subsurface condition as described in this Section, the General Contractor shall notify the Owner, who will in turn notify the appropriate agency as soon as practicable, but in no case more than 24 hours after discovery. If any unanticipated subsurface condition is discovered, work must stop, and the project proponent must consult with Project Environmental Consultant. Project Environmental Consultant shall be a California licensed Professional Geologist or Engineer, who will provide guidance on how to proceed in accordance with applicable laws and regulations.

6.2 Underground Storage Tanks, Sumps, and Clarifiers
Buried physical objects including underground storage tanks (USTs), sumps, clarifiers, barrels, drums, containers, or other yet unknown underground structures of potential concern, and/or visual or olfactory evidence of contamination could be discovered during Site grading and excavation activities.

For UST encounters, or any subsurface feature qualifying as a UST, the contractor must stop work, notify the Los Angeles County Fire Department (LACFD) and obtain a permit for the removal and closure of the UST prior to proceeding. If an UST is broken open, then the contractor should immediately take action to stop or prevent a release by removing fluid, and then notify LACFD. All UST closure activities must be conducted in accordance with LACFD requirements.

6.3 Stained, Visually Distinct or Odorous Soil
As identified above, the possibility exists for encountering potentially contaminated soil, outside the currently known areas of contaminated soil. The General Contractor will take precautions to monitor for the presence of potentially contaminated soil using field screening tools, as described in this SMP. If suspected potentially contaminated soil is encountered, handling, management, and disposal of such soil will follow the protocols identified.

7.0 Storm Water Management
All soil excavation and stockpiling activities must conform to the requirements and stipulations of the Site’s SWPPP.

8.0 Exported Soil Management
Contractors generating surplus soil which is VOC or petroleum-contaminated and cannot be reused onsite and is to be removed for offsite disposal, are responsible for all testing, waste classification, selection of an appropriate disposal site, transportation, and all documentation related to offsite disposal of soil, debris, or other waste, resulting from the project proponent’s activities. Although Site investigation data indicate that soil within the development area would generally not be classified as hazardous waste, soil removed from the Site must be characterized and managed in accordance with Title 22 of the California Code of Regulations, Division 4.5, Chapter 11, if applicable, as well as the requirements of the disposal facility, and any other applicable law. To the extent applicable, labeling requirements for transportation of waste shall additionally be in accordance with Title 29 of the Code of Federal Regulations, Parts 172 and 173.

Soils designated for export from the Site shall have met either of the following criteria:

1. Laboratory analytical results of soil samples for metals, VOCs, and TPH, will initially be compared to DTSC Human Health Risk (HHRA) NOTE NUMBER: 3, DTSC-modified Screening Levels (DTSC-SLs) (HHRA Note #3) for residential land use and/or EPA Regional Screening Levels for residential land use (RSL-r) for compounds not covered by HHRA Note #3. Also, no PID readings greater than 50 ppm, and no odor, discoloration, debris, or suspect ACM have been observed.

Soils meeting all of the above criteria may be re-used onsite if suitable or transported off-site.

2. If laboratory analytical results of soil samples for metals, VOCs, or TPH, are greater than their respective screening values, or if soils are observed to contain odors, discoloration, debris, suspect ACM, and/or have PID readings greater than 50 ppm, then the soils will be considered unacceptable for use as fill material and further evaluation may be required to determine the appropriate waste disposal option.

If unacceptable levels of any of the above listed chemicals are reported, further analysis by soluble threshold limit concentration (STLC) analytical procedures and/or toxicity characteristic leaching procedure (TCLP) may be required for confirmation and characterization. Furthermore, additional laboratory analyses such as for pesticides and herbicides, may be required for disposal profiling purposes.

Based on laboratory analytical results, proper transportation and disposal methods shall be determined. Note: STLC and TCLP analytical procedures may take as much as two (2) to three (3) days to receive results.

The soil shall not be removed from the Site until all appropriate analytical testing is completed. If the excavation contractor elects to stockpile the soil, then each individual stockpile generated will be no greater than 400 cubic yards. The stockpile will then be sampled for confirmation and characterization purposes. All stockpiles that are considered to be unacceptable must be placed on top of plastic sheeting and will be covered by plastic sheeting by the excavation contractor until such time confirmation results are received and proper disposal is determined.

See Sections 5.2 and 5.4 for procedures and requirements for stockpiling soils impacted with VOCs.

9.0 Soil Disposal
All soil to be disposed will be taken only to a certified and permitted California landfill or an equivalent out-of-state landfill, as appropriate and as determined by the waste profile.

Impacted soil that is to be exported from the Site shall be disposed of off-site to a disposal facility approved by the Owner. The contractor’s project manager and/or superintendent shall obtain approval from the Owner prior to disposal.

The Contractor shall work with the owner to ensure efficient and timely removal of impacted stockpiled soil. Soils impacted by chemical contaminants are subject to one of several state or federal management and disposal regulatory structures, depending upon the type and severity of contamination. In general, soils classified by laboratory analyses as Non-RCRA (United States Resource Conservation and Recovery Act) are the least impacted by contamination. Soils classified as California Hazardous are more significantly impacted, and soils designated as RCRA are most heavily impacted by contamination.

Licensed and certified disposal sites should be selected to ensure that a disposal facility is approved to accept the contaminated soil and that the facility meets with the Owner’s approval.

For purposes of document and liability management, only those individuals authorized by the Owner or their designee shall sign Uniform Hazardous Waste Manifests (UHWM) for the off-site disposal of any soil whose transport and disposal requires a UHWM. The Owner shall provide all information to be contained on the manifest, including Environmental Protection Agency Generator Identification Number and the name and location of the treatment, storage and disposal facility which will accept the waste. Clean, non-hazardous and non-regulated soil may be shipped under a standard bill of lading and may be signed by individuals not approved for UHWM management.

10.0 Limitations
This Soil Management Plan has been prepared for the sole benefit and exclusive use of Willdan during the renovations planned for the Tree Boundary and River Road areas of the Cudahy Park Renovation Project in the City of Cudahy, Los Angeles County, California in accordance with the terms and conditions under which it was prepared. Our services have been performed in accordance with applicable state and local ordinances and generally accepted practices in the geosciences. No other warranty, either express or implied, is made.

Reliance on this workplan by third parties is at the third parties sole risk. Site exploration identifies actual subsurface conditions only at those points where samples are taken, when they are taken. Data derived through sampling and analytical testing are extrapolated by geoscientists who then render an opinion about overall general subsurface conditions. The possibility of different local soil conditions cannot be discounted. Converse is not responsible or liable for any claims or damages associated with the accuracy or completeness of information provided by others. In the event that changes in the nature of the Site occur, or additional, relevant information about the Site is brought to our attention, the guidelines and procedures contained in this report may not be valid unless these changes and additional relevant information are reviewed and the conclusions of this report are modified or verified in writing.

This document should be implemented during excavations and rework of soils performed at the subject site. This document is not intended to be suitable for use on extensions or modifications to the project or for use on any other project other than the currently proposed, as it may not contain sufficient or appropriate information for such uses.

Appendix 2 – Procedures to Demonstrate Intra-Instrument Precision An owner or operator shall perform the following procedures to demonstrate the intra-instrument precision of all PM10 monitors as required in paragraph (d)(7).

1. Ensure monitors are identical in make and model, settings, and configuration.

2. Ensure monitor inlets are at the same height and located within 4 meters of each other but no less than 1 meter apart for the duration of the test.

3. Power on the monitors and turn on the heated sampler inlet. Allow the monitors to warmup per manufacturer’s recommendations or when readings have stabilized.

4. For each monitor, conduct a zero calibration in accordance with manufacturer’s instructions, then conduct a manual zero check by removing any sampling inlet and installing a filter, rated by the manufacturer to achieve a 99.97 percent control efficiency for 0.3 micron particles, on the inlet of the monitor for a minimum of 10 minutes. If the monitors are operated using an auto-zero check procedure that directs filtered particle-free air into the measurement chamber, conduct the zero check in accordance with manufacturer’s instructions.

5. Log the PM10 concentration reading every minute, and calculate and record the average of the readings of the manual zero check. The average of the manual zero check readings shall be 0 ± 3 micrograms per cubic meter before proceeding to Step 6. If conducting an autozero check, the monitor shall pass the zero check in accordance with manufacturer’s instructions before proceeding to Step 6. If any monitors fail either the manual zero check or the auto-zero check, the owner or operator shall conduct a zero calibration in accordance with manufacturer’s instructions and/or correct any issue(s) causing the failure, followed by conducting a passing zero check on the PM10 monitor(s) in accordance with Steps 4 and

5. 6. Remove the filter and install the monitor inlet as required. After waiting 10 minutes, operate the monitors simultaneously and log the PM10 concentration reading every minute for a minimum of 60 minutes.

7. Calculate the intra-instrument precision using either of the following equations:
a. Intra-instrument precision in relative standard deviation or correlation of variation (%) when ambient PM10 concentrations are greater than or equal to 15 micrograms per cubic meter:

𝑃𝑃 =
𝑆𝑆𝑡𝑡
𝐶𝐶𝑡𝑡
𝑥𝑥 100%
where,
P = Intra-instrument precision in percent (%);
St = Standard deviation of the averaged PM10 concentration readings from all tested monitors over the time t of testing duration, to be calculated as:

𝑆𝑆𝑡𝑡 = �∑(𝑥𝑥𝑖𝑖 − 𝑥𝑥̅)2
(𝑛𝑛 − 1)
where,
xi = Mean of the PM10 concentration readings for a tested monitor over time t of testing duration,
𝑥𝑥̅= Mean of the averaged PM10 concentration readings from all tested monitors over the time t of testing duration, and 𝑛𝑛 = Number of tested monitors; and
Ct = Mean of the averaged PM10 concentration readings from all tested monitors over the time t of testing duration; or
b. Intra-instrument precision in absolute value (micrograms per cubic meter) when ambient PM10 concentrations are less than 15 micrograms per cubic meter:

𝑃𝑃 = 𝑆𝑆𝑡𝑡
where,
P = Intra-instrument precision in micrograms per cubic meter, and St = Standard deviation of the averaged PM10 concentration readings from all tested monitors over the time t of testing duration.

8. Record the results of the calculations.

1.0 INTRODUCTION
This Health and Safety Plan (HASP) has been prepared by Converse Consultants (Converse).

Converse was retained by Willdan, to prepare a Soil Management Plan (SMP) for the for the proposed Cudahy Park Renovation Project.

2.0 SITE BACKGROUND
In January 2015, the City of Cudahy and State of California Department of Toxic Substances Control (DTSC) signed a Covenant to Restrict Use of Property (Covenant), Environmental Restriction, County of Los Angeles, Assessor Parcel Number 6224-014-905. Pursuant to Civil Code Section 1471, the DTSC determined that the Covenant was reasonably necessary to protect present or future human health or safety or the environment as a result of the presence on the land of hazardous materials as defined in Health and Safety Code Section 25260.

Pursuant to Civil Code Section 1471, and Health and Safety Code Section 25355.5, the City of Cudahy and DTSC agreed that the use of the Site be restricted as set forth in the Covenant.

According to the Covenant, the Site was remediated pursuant to a Removal Action Workplan (RAW) developed under Chapter 6.8 of division 20 of the Health and Safety Code, under the oversight of DTSC. The RAW provided that a deed restriction be required as part of the site remediation, because lead, benzo(a)pyrene, toluene, and xylenes, remain at depths of one-foot or more below the surface of the Tree Boundary Area and River Road Area. Following approval of the RAW, soils were excavated to depths of 8 to 14 feet below ground surface (bgs), graded, and then backfilled with clean soil. As detailed in the Final Removal Action Completion Report that was approved by DTSC on December 8, 2005, a portion of the subsurface soils within 10 feet of the surface of the Tree Boundary Area contain hazardous substances including lead (1,103 parts per million [ppm]), benzo(a)pyrene (4.18 ppm), benzene (1.3 ppm), toluene (2.3 ppm), and xylenes (2.9 ppm). The soils underneath the River Road Area within 10 feet of the surface contain lead (2,160 ppm), and benzo(a)pyrene (2.71 ppm). The DTSC further concluded that the remainder of the Site, as remediated, does not present an unacceptable threat to human safety or the environment.

The Covenant covers two (2) specific areas of the Site, identified as the “Tree Boundary Area” and “River Road Area”.

2.1 SITE LOCATION
Cudahy Park is located at 5220 Sant Ana Street in the City of Cudahy, Los Angeles County, California. Cudahy Park is generally bounded by Park Avenue Elementary School to the north, River Road to the east, and residences to the south and west. The SMP covers both the Tree Boundary and River Road portions of Cudahy Park. The Tree Boundary Area is located in the area now generally bounded by the basketball court and parking lot on the north, River Road on the east, and baseball fields on the south and west. The River Road Area is located at the eastern part of Los Angeles County Assessor’s Parcel No. 6224-014-905.

2.2 CLIMATE
Cudahy has a Mediterranean climate with hot, dry summers and mild, damp winters, and a large amount of sunshine year-round. Summers are characterized by sunny days and very little rainfall during June through September. Fall brings cooler temperatures and occasional showers, as well as seasonal Santa Ana winds originating from the northeast.

Prevailing winds are generally from the northeast and rarely exceed 9 miles per hour (mph).

Greatest wind velocities are generally associated with the Santa Ana Winds season, typically in late October through November, and can reach 80+ mph.

3.0 PROJECT SAFETY PERSONNEL
This HASP has been prepared by Converse. The Consultant (to be hired by the Project Proponent [PP]) is responsible for ensuring compliance of their personnel, subcontractor personnel, and visitors to the Site with the HASP and its provisions. The Corporate Health and Safety Officer (CHSO), Project Health and Safety Officer (PHSO), and Site Health and Safety Officer (SHSO) are responsible for the distribution of this HASP and for the compliance audit.

It is anticipated that the PHSO, SHSO, and Project Field Supervisor (PFS) will be the same person.

The SHSO has the authority to inspect work at any time. If they determine that the provisions of the HASP are inadequate to provide a working environment conducive to worker safety, then theyare to inform the PM of individuals whose on-site presence jeopardizes their health and safety or the health and safety of others.

4.0 SCOPE OF WORK
This HASP covers the field work and field activities associated with the renovation activities proposed in the Tree Boundary and River Road areas of the Site. The field activities are expected to include, but are not limited to renovation activities, oversight and possible soil matrix sampling. Detailed information is provided in the SMP.

5.0 SITE HAZARD ANALYSIS
Park renovation activities in the Tree Boundary and River Road portions of Cudahy Park may result in exposure to biological, chemical, and physical hazards. Preparation of this HASP was based on review of the SMP.

5.1 CHEMICAL HEALTH HAZARDS
The chemicals of concern (COCs) may form toxicological exposure hazards and enter the body via inhalation, ingestion, skin absorption, and/or injection. The permissible exposure limit (PEL) is defined by the California Department of Occupational Safety and Health (CAL/OSHA) in the California Code of Regulations (CCR), Title 26, Section 5155, and other sections, where necessary. PELs refer to the airborne concentrations of substances and represent conditions during which it is believed that nearly all workers may be repeatedly exposed, eight (8) hours per day, for a 40 year working lifetime, without adverse effect. Variations in individual susceptibility may result in a small number of workers experiencing discomfort to some or all the chemicals at concentrations equal to or below the PEL. A smaller percentage of individuals may be affected more seriously from exposures at or below the PEL due to aggravation of a pre-existing condition or by development of an occupational illness. The PEL is based on research conducted by the National Institute for Occupational Safety and Health (NIOSH) and the American Conference of Governmental Industrial Hygienists (ACGIH) and are based on the best available information from industrial experience, animal studies, and other sources.

The time-weighted average (TWA) PEL represents a time-weighted exposure for an eight (8)- hour workday, 40 hours per week. Most PELs are expressed as time-weighted averages.

CAL/OSHA also has promulgated short-term exposure limits (STEL; usually 15 or 30 minutes) for certain substances. A few substances have ceiling concentration (the highest allowable concentration in the workplace) that cannot be exceeded, even instantaneously. Substances Cudahy Park Renovation Project, Project # PRE-001 Document Control 335 of 1214 Page 365 of 1692 Converse Project No. 24-41-114-02 5
that can enter the body in a gaseous form through the skin are denoted by CAL/OSHA with an “s.”

5.1.1 CHEMICALS OF CONCERN
Investigations conducted at the Site identified lead, benzo(a)pyrene, benzene, toluene and xylenes in soil at the Site as the primary COCs.

The applicable exposure limits for the chemicals listed above are presented in the following text and in Tables. The following is a brief description of the potential hazards associated with these compounds.

*Coal tar pitch volatiles (benzene soluble fraction, anthracene, benzo(a)pyrene, phenanthrene, acridine, chrysene, pyrene) exposure limit values used for benzo(a)pyrene Toxicological profiles for the chemicals of concern were obtained from the Agency for Toxic Substances and Disease Registry (ATSDR). No profile for benzo(a)pyrene was available. The profiles are as follows:

Lead
Lead is a heavy, ductile, soft, gray solid. It is non-combustible with a melting point of 621oF and vapor pressure of 0.0 mm of Hg. Lead is incompatible with strong oxidizers, hydrogen peroxide, and acids. Ingestion or inhalation of lead may result in weakness, insomnia, facial pallor, pal eye, anorexia, malnutrition, abdominal pain, colic, anemia, gingival lead line, tremors, paralysis of wrist/ankles, kidney disease, and hypertension. It is also irritating to the eyes.

Benzene
Benzene is a colorless liquid with a petroleum-like odor. It evaporates into the air very quickly and dissolves in water. It is highly flammable. Inhalation or ingestion of benzene may result in a decrease in the number of red and white blood cells. This can lead to anemia and bone marrow cancers, including acute myelogenous leukemia.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 336 of 1214 Page 366 of 1692 Converse Project No. 24-41-114-02 6
Toluene
Toluene is a clear, colorless liquid with a distinctive smell. Toluene may affect the nervous system. Low to moderate levels can cause headaches, dizziness, tiredness, confusion, weakness, drunken-type actions, memory loss, nausea, and loss of appetite. These symptoms usually disappear when exposure stops.

Xylenes
There are three forms of xylene in which the methyl groups vary on the benzene ring: metaxylene, ortho-xylene, and para-xylene (m-, o-, and p-xylene). These different forms are referred to as isomers. Xylene is a colorless, sweet-smelling liquid that catches on fire easily. High levels of exposure for short or long periods can cause headaches, lack of muscle coordination, dizziness, confusion, and changes in one's sense of balance. Exposure of people to high levels of xylene for short periods can also cause irritation of the skin, eyes, nose, and throat; difficulty in breathing; problems with the lungs; delayed reaction time; memory difficulties; stomach discomfort; and possibly changes in the liver and kidneys. It can cause unconsciousness and even death at very high levels.

5.2 BIOLOGICAL HAZARDS
Potential biological hazards may include plants, ticks, snakes, various stinging insects, and biological health hazards (BHH). Some of the most common biological hazards can be prevented or the effects reduced by over-the-counter medications. These medications, as recommended by local pharmacists, will be kept in supply in the first aid kit. The best protections against biological hazards are to wear appropriate clothing and avoid exposure to the hazard. Workers who know they are sensitized to any biological hazard should not perform any task that would increase their risk for anaphylactic shock. Additionally, the SHSO should be informed of any sensitization to biological hazards.

5.3 PHYSICAL HAZARDS
Listed below are the types of physical hazards that may be present during activities at the Site:
• Slip, Trip, or Fall - These types of hazards result from unleveled surfaces, slippery surfaces, and hard-to-see objects located across walking paths (e.g., rope, cords, etc.), and are responsible for over 60% of work-related injuries. • Housekeeping and Sanitation - In order to permit safe and efficient work conditions, all work areas will be kept clean and free from debris. All hand tools will be kept in storage until they are needed for use. Trash containers will be leak proof, clean, and maintained in a sanitary condition. If vermin are encountered, an approved extermination method will be initiated. Potable water will be used for first aid, drinking, and personal hygiene purposes. All floors will be kept free from standing water. Disposable drinking cups will be provided, along with water coolers. Community drinking cups will not be permitted. • Falling Objects - Hard hats, safety glasses, and steel-toed footwear will be required for personnel in all work areas.
• Traffic Safety - During normal business hours, there may be a significant level of traffic coming to and from the Site Pedestrian traffic on the Site may be at risk as traffic enters and exits the Site.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 337 of 1214 Page 367 of 1692 Converse Project No. 24-41-114-02 7
• Noise - High noise levels (in excess of 85 decibels [db] for extended periods) can result in temporary and permanent loss of hearing. Areas where noise levels exceed 85 db will be posted and hearing protection will be provided and worn. Noise dosimetery will be performed as required by Cal/OSHA specifications.

5.4 REQUIRED SAFETY MEASURES FOR PHYSICAL HAZARDS
Listed below are the types of safety measures to be taken to reduce physical hazards that may be present at the Site:

Potential Hazard Required Safety Measure
Head Injury Hard hats will be worn.

Eye Injury Safety glasses will be worn around moving machinery.

Foot Injury Safety shoes with steel reinforced toes will be worn.

Other Injury Guards are required on all moving parts, belts, and pulleys.

Fire Fire or tobacco smoking will be strictly prohibited within the containment area. Fire extinguishers will be readily available.

Inhalation The vapor and dust concentrations that might be encountered may exceed currently recommended exposure limits. Respiratory protection must be used if 80% of the exposure limits are exceeded. Appropriate protective equipment will be used, as directed by the PFS/SHSO.

Noise Ear plugs will be used whenever loud machinery is in use.

Dermal exposure Contact of sufficient duration to cause significant absorption of toxic components is highly unlikely. Repeated daily or prolonged contact with contaminated soil or water, however may be expected to defeat the skin and perhaps over a long period of time lead to irritation and dermatitis. For this reason, direct skin contact with contaminated soil or water will be avoided by wearing protective gloves. However, if skin contact does occur, the exposed areas will be washed with soap and water and rinsed thoroughly.

Equipment Failure If monitoring instruments or any safety equipment fails, work will be suspended until repairs or replacements can be found. In case of working equipment failure, the PFS/SHSO will ensure that no hazardous conditions prevail before authorizing further work.

Slip, Trip, and Falls Appropriate warning signs will be posted, wherever this danger exists.

Underground Utility Location of all underground utility lines will be determined before commencing work. In case of breach of a line, electricity and gas supply will be shut off.

Traffic Hazards When working in an area open to vehicular traffic, the work area will be clearly delineated to restrict vehicular access. When working in public right-of-ways, lane closures must be conducted in compliance with the guidelines set forth in the State of California Manual of Traffic Controls (Watch handbook) and any additional local ordinances or guidelines. Personnel exposed to vehicular traffic will use high-visibility clothing in accordance with the requirements of 8 CCR 1598(c).

Cudahy Park Renovation Project, Project # PRE-001 Document Control 338 of 1214 Page 368 of 1692 Converse Project No. 24-41-114-02 8

5.5 HEAT STRESS
Heat stress and associated complications can be the most prevalent health concerns on-site, especially when Personal Protective Equipment (PPE) is used. Refer to Section 9 for a description of PPE for this Site. Heat stress problems for workers can occur more often than chemical-related hazards and must therefore be regarded with caution.

If precautions are not taken, workers in PPE may experience varying degrees of heat stress. All workers will be encouraged to drink increased amounts of fluids (which will be readily available at the Site at all times, at an appropriate location). All personnel will monitor each other to determine if any signs of heat stress become apparent. A work/rest regimen will be instituted to reduce heat-related exhaustion.

The PFS/SHSO will be trained to recognize the symptoms of heat rash, heat cramps, heat exhaustion, and heat stroke. Using the following procedures will help reduce the potential for workers to experience symptoms of heat stress:
• Provide plenty of liquids to replace loss of body fluids, including salt water solutions or commercial mixes such as Gatorade (registered product). Commercial mixes may be preferred by individuals on low sodium diets
• The following work/rest regimen will be followed for field workers performing light/moderate work at PPE level C or level B outdoors:

Work/Rest Regimen Temperature
°F °C
Continuous work <79 27
75% work/25% rest each hour 79 27
50% work/50% rest each hour 84 30
25% work/75% rest each hour 88 32
In order to evaluate the adequacy of this work/rest schedule, heart rate (pulse) determination will be made involving each worker leaving the work area and again approximately one (1) minute after exit. If the exit pulse exceeds 0.7 times the difference between 220 and the age of the individual, or if the one (1) minute pulse exceeds 110 beats per minute, then the work schedule will be reduced by 10 minutes and, therefore, the rest period will increase by the same 10 minutes each hour.

6.0 GENERAL HEALTH AND SAFETY REQUIREMENTS
Records documenting the Site safety program will be maintained. This will include information about medical clearance for each individual working at the Site, training, safety briefing, distribution of the HASP, incidents, safety completion report, and posting requirements.

Records will be maintained in a health and safety logbook and appropriate health and safety forms.

Records will be kept consistent with all applicable CAL/OSHA regulations. The following records will be maintained at the offices of each subcontractor:

Cudahy Park Renovation Project, Project # PRE-001 Document Control 339 of 1214 Page 369 of 1692 Converse Project No. 24-41-114-02 9
• Hazard communication training
• Hazardous waste site training
• Respiratory protection training
• Respirator assignment
• Medical surveillance
• Safety inspection reports
• Personal monitoring records
• Accident logs
• CAL/OSHA logs (200 form or equivalent).

The PM or PFS will maintain the following records at the Site:
• Persons on-site, their affiliation, and purpose
• Telephone conversations
• Sampling activities
• Chain-of-custody forms
• Work progress
• Site safety inspection reports
• Tailgate safety meeting forms
• Worker illness and/or injury reports
• PEA Workplan (and changes)
• HASP (and changes)
• Daily work activities and conditions
• Accident log.

Subcontractors will maintain employee records in a manner consistent with the applicable regulations.

6.1 MEDICAL CLEARANCE AND MONITORING
All personnel must obtain health and safety clearances before beginning work at the Site.

Employees will be active participants in the Consultant’s Medical Surveillance Program. Project personnel who may be required to wear respirators must provide evidence that they have been cleared by a physician to wear respirators. All field personnel are to be an active participant in the Consultant’s Respiratory Protection Program.

6.2 SAFETY ORIENTATION MEETING
All field personnel must attend a safety orientation meeting before commencing fieldwork. The meeting will be scheduled and conducted by the PM, PFS, or SHSO. The dates of briefing sessions and attendees must be recorded on the Safety Meeting Form (Figure1 at end of HASP). Safety orientation/ training meetings must be convened:
• Before field work begins
• When there are modifications to the HASP that are applicable to field personnel • When additional personnel begin fieldwork.

Respirator fit testing should be conducted at the safety meeting for all individuals who have not been test fitted and who may be required to wear respirators. The meeting will include Cudahy Park Renovation Project, Project # PRE-001 Document Control 340 of 1214 Page 370 of 1692 Converse Project No. 24-41-114-02 10
presentation of the HASP. The NIOSH report regarding confined spaces will be presented at the initial safety meeting if deemed appropriate by the PFS/SHSO.

6.3 TRAINING
Participation in field activities will not occur until all participants have been trained to the level required by their job function and responsibility. The specific types of training required include orientation for new employees, basic training for first time hazardous waste workers, supervisor training, advanced training, Site-specific training, first aid, and refresher training.

Personnel on this project are required to have completed 40 hours of training. This will include personnel involved with investigations and activities where contaminated soils may likely be encountered. Personnel for each task will be evaluated on-site by the SHSO, as per Hazardous Waste Operations and Emergency Response Standard (HAZWOPER) training.

6.4 DISTRIBUTION OF THE HASP
A copy of this HASP must be available to each employee and subcontractor. The Consultant’s employees and subcontractors must acknowledge reviewing of the HASP and agree to comply with its provisions in writing by signing the Acknowledgement Statement (on Figure 1).

6.5 INCIDENT REPORTING
Injuries, exposure, illnesses, safety infractions, and other incidences must be reported to the SHSO within 24 hours of occurrence.

An incident is any event listed below:
• Illness resulting from chemical exposure or unknown causes • Physical injury, including those that do not require medical attention • Fire, explosions, and flashes resulting from activities performed by the Consultant’s personnel and their subcontractors
• Site damage
• Vehicular accidents occurring on-site or while traveling to and from the Site(s) • Infractions of safety rules and requirements
• Unexpected chemical exposure (indicated by irritation of eyes, nose, throat, or skin).

Accidents on-site where the Consultant is not retaining the subcontractor or individual will be reported, if injury or illness relates to the Consultant’s task. Serious or fatal on-site injuries will be reported as soon as possible to the CHSO.

6.7 POSTING REQUIREMENTS
The following information will be posted or readily available on-site:
• Emergency phone numbers
• Directions to the nearest hospital
• HASP
Cudahy Park Renovation Project, Project # PRE-001 Document Control 341 of 1214 Page 371 of 1692 Converse Project No. 24-41-114-02 11

6.8 AUDITING
The success of the Consultant’s Health and Safety Program will be evaluated through statistical reporting (such as the OSHA 200 logs and insurance experience) and formal audits. Audits will be conducted by the CHSO. Audits may be announced or unannounced, and a formal health and safety audit report will be provided to the PM. Following completion of the field audit, a verbal review of concerns will be completed with the PM and SHSO. Inspections will be made to identify and evaluate hazards when:
• The program is first established
• New substances, processes, procedures, or equipment are introduced to the workplace that represent a new occupational safety and health hazard • Whenever the Consultant is made aware of a new or previously unrecognized hazard.

6.9 INJURY AND ILLNESS PREVENTION PROGRAM
This entire document, including the appendices, serves as an Injury and Illness Prevention Program (IIPP). The persons with authority and responsibility for implementing the program are identified in Section 3.0.

The system for ensuring that employees comply with safe and healthy work practices includes:
• Generation of a HASP
• Auditing by the CHSO
• Daily field health and safety oversight by the SHSO
• Daily tailgate safety review meetings
• Review of employee and subcontractor training.

Employees and subcontractors who are not prepared to abide by the health and safety provisions contained within this document will not be allowed on-site. Individuals observed violating requirements of this document will be given a formal “Notice of Violation.” Should violations continue, or not be corrected, the individual(s) will be removed from the Site(s).

The tailgate safety meetings, training sessions, and postings at the Site are the three (3) major sources of communication between employees. The Consultant’s internal communication system includes:
• A reporting matrix between the SHSO and CHSO
• The communications associated with the auditing program.

The auditing program also complies with Title 8, CCR Section 3203(a)(4), which states that an employer must:
“Include procedures for identifying and evaluating work place hazards including scheduled periodic inspections to identify unsafe conditions and work practices.”
The Consultant’s incident/accident reporting system is the procedure for investigating injury or occupational illness, in addition to its medical surveillance program. This document addresses the applicable sections of the Title 8 CCR, Sections 1509 (Construction) and 3203 (General) regarding the IIPP. Additional information regarding the internal programs of the Consultant, Cudahy Park Renovation Project, Project # PRE-001 Document Control 342 of 1214 Page 372 of 1692 Converse Project No. 24-41-114-02 12
which are not specific, are discussed in the Consultant’s Health and Safety Manual (HSM). The HSM will be posted on-site.

6.10 FIT FOR DUTY
While the Consultant does not seek to interfere with the off-duty and personal conduct of its employees, subcontractors, clients, or visitors, certain types of off-duty conduct may interfere with the legitimate business interests of the Consultant at the Site. It is the responsibility of the Consultant’s employees, subcontractors, clients, or visitors to ensure that they are fit to perform their required duties at the Site. The SHSO has the responsibility to ensure that each individual signing the tailgate meeting is fit for duty. Activities that may affect the fitness of individuals at the Site include:
• Consumption of alcohol
• Use of illegal or controlled substances
• Certain prescription or over-the-counter medicines
• Altered mental state
• Personal injury
• Fatigue.

Any individual found to be unfit for duty will be prevented from entering/working at the Site until it is determined they are fit to return to duty. The SHSO will make an incident report and inform the PM of the incident. Subcontractors who have personnel unfit for duty will be notified and provided with the opportunity to replace the impaired individuals at the Site.

7.0 EXPOSURE MONITORING PLAN
Air monitoring may be used to identify and quantify levels of hazardous substances that could be present at the Site. This may be accomplished by the use of personal monitoring instruments and direct reading instruments for personal and Site monitoring, respectively.

A wind direction indicator may be utilized to ensure the direction that personnel will move when instructed to do so or in any emergency. Air monitoring equipment will be used to measure airborne levels of organic vapors during sampling activities. Monitoring may be done using a photo-ionization detector (PID) or equivalent, for organic vapors. The PID will be calibrated prior to each day’s activities. The calibration will be recorded in a logbook and the instrument will be re-calibrated during the day at the discretion of the PFS/SHSO. Background readings will be obtained at an upwind location.

Work will be started with all personnel using Level D personal protective clothing. For areas where volatile chemicals hazards are suspected, the first person entering the work zone will carry the PID and monitor concentration levels of vapors in the work area before anyone else is allowed into the work zone. The breathing zone will be monitored continuously.

In the event Level B protective equipment is used, one (1) person working in the Exclusion Zone (EZ) will be fitted with a personal sampling pump (dosimeter). This system will remain in the EZ for eight (8) hours continuously, passing from person to person. At the end of the eight (8) hour period, the cartridge and filter will be removed and sent to a State-certified laboratory for analysis. Hence, the average exposure of personnel working in the EZ will be known and can Cudahy Park Renovation Project, Project # PRE-001 Document Control 343 of 1214 Page 373 of 1692 Converse Project No. 24-41-114-02 13
be compared to the TWA. This will act as a confirmation of the conclusions drawn by use of the PID.

Air monitoring equipment such as aerosol monitors (personal data rams) may also be used to measure airborne levels of dust during field activities. Aerosol monitors shall be checked daily to confirmed that they properly calibrated and in good working condition. Real-time information regarding dust levels will be posted daily and discussed with Site workers. Air monitoring samples will be collected over an eight (8) to 10-hour period each day that Site renovation excavation and/or loading activities are conducted. The air-monitoring professional will check the monitoring equipment every 15 minutes during operation.

In addition to the real-time dust monitoring, air samples may also be collected for the potential analysis of COCs. Pumps will be used to draw air through a mixed-cellulose ester (MCE) filter contained within a closed-face polysterene cassette using over an eight (8) to 10-hour period each day. The cassette samples will initially be archived. However, should the RA contractor determine that the Site Action Level for total dust was exceeded during the course of the RA (see Chart below), the cassette samples may be submitted to a laboratory analyzed for lead and arsenic concentrations.

Dust levels, and potentially airborne concentrations of the COCs, shall be monitored at the following general locations:
• Upwind (offsite property if possible).
• Proximate to the exclusion zone adjacent to and downwind of the equipment operator. • One Fenceline location.
• One Downwind location.
• As deemed necessary to determine employee exposure (to be determined by the contractor).

Site safety procedures for total dust and lead, including dust control measures, will be based on the Action Levels specific in the chart below:

Based on the relatively low reported concentrations of benzo(a)pyrene, benzene, toluene, and xylenes in site soils, the total dust action levels in the table below are deemed sufficient to use in place of chemical-specific action levels.

If Site Action Levels are exceeded on the integrated air monitors, then a Certified Industrial Hygienist will be immediately consulted.

Site Action Level for total (unknown) VOCs is 10 ppm as measured by real-time PID. d Community Action Level for total dust/particulate is based on SCAQMD regulations.

Community Action Level for a specific chemical dust is normally based on the available ATSDR MRL Equivalent Air Concentrations.

Community Action Level for lead is 0.0015 µg/m3 based on the National Ambient Air Quality Standard.

Community Action Level for lead dust is determined based on review of available data regarding soil lead concentrations and will be protective of Site workers and surrounding area inhabitants. Site dust levels will be measured using real-time aerosol monitors.

8.0 SITE CONTROL
The purpose of Site control is to minimize potential contamination of workers, protect the public from the Sites hazards, and prevent vandalism. In order to control activities and movement of personnel and equipment at the Site, a Site control program will be set up. The basic components of a Site control program include establishing work zones, a buddy system, Site security, safe work practices, sanitation, Site communication, and visitor clearances into the work area(s). These components are described below.

8.1 SITE WORK ZONES
Access to hazardous and potentially hazardous areas must be controlled to reduce the probability of physical injury to field personnel, visitors, and the public. A hazardous or potentially hazardous area includes any area where field personnel are required to wear PPE.

The establishment of work zones will help ensure that: personnel are properly protected against hazards present where they are working, work activities and contamination are confined to appropriate areas, and personnel are located and evacuated in an emergency. Three (3) work zones will be established around any intrusive activity: the EZ, the contaminant reduction zone (CRZ), and the support zone (SZ). The area work zones will be clearly identified, as appropriate, with barrier tape or other demarcation methods.

A restricted zone will be maintained to a distance of 15 feet from the work activity area.

Protective clothing and equipment, as described below, are to be worn by all personnel working within the restricted zone.

The precise locations of all work areas, the decontamination area, equipment storage areas, rest areas, restroom facilities, and routes of exit will be established in the field. The support zone will be upwind from the work zone, when possible. All persons entering the subject Site will identify themselves to the PM, PFS, or SHSO for proper documentation.

8.1.1 Exclusion Zone
The EZ is defined as the area where contamination is either known or likely to be present, or where activities will create the potential to cause harm to personnel. The EZ initially will be established for each specific task based on the presence of contaminants within the area, and subsequently may be altered by the SHSO based on new data or observations. The outer boundary of the EZ, known as the Hotline, will be clearly delineated with barrier tape and/or traffic barriers. Warning signs will be placed around the perimeter of the EZ warning of a hazardous work zone. Access Control Point(s) (ACPs) will be established at the periphery of the EZ to regulate the flow of personnel and equipment into and out of the EZ, and to verify that relevant procedures for entry and exit are followed. Access will be restricted to personnel with Cudahy Park Renovation Project, Project # PRE-001 Document Control 345 of 1214 Page 375 of 1692 Converse Project No. 24-41-114-02 15
appropriate training and documentation, and wearing appropriate PPE, as defined in this HASP.

Eating, drinking, and smoking are prohibited within the EZ.

8.1.2 Contaminant Reduction Zone
The CRZ is the area where personnel conduct personal and equipment decontamination. Its location will be established based on air monitoring results, and it will be surrounded by barrier tags, traffic cones, and/or warning signs. It is a transition area between contaminated areas and clean areas, and provides an area to prevent or reduce the transfer of contaminants that may be present on personnel or equipment returning from the EZ. No disposable outer protective work clothing will leave the CRZ. Emergency and first aid equipment, equipment resupply (gloves, etc.), and temporary rest facilities (chairs, shade, liquids, etc.) will be available in the CRZ.

Access into and out of the CRZ from the EZ is controlled through ACPs. The boundary between the CRZ and the SZ, the Contamination Control Line, separates the low contamination area from the clean SZ. Entry into the CRZ from the SZ will be controlled through ACPs. Activities to be conducted in the CRZ will require PPE as defined in the decontamination procedures. Exit from the CRZ requires the removal of any suspected or known contaminated PPE and compliance with decontamination procedures. A primary and secondary CRZ will be established. Exit through the secondary CRZ will occur only during emergencies.

8.1.3 Support Zone
The SZ is a clean area where the chance of encountering hazardous materials or conditions is minimal. It contains administrative and other support functions, including the Command Post (CP). CP personnel are responsible for supervision of all field operations and field teams. CP personnel are also responsible for maintaining internal and external communication and alerting the proper authorities in the event of an emergency. Telephone communication will be maintained by the use of cellular phones at the Site. Emergency telephone numbers and hospital route maps will be kept here. Health and safety records and up-to-date copies of the HASP will be kept in the SZ. Break/conference, lunch, storage/supply, security, sanitation, and emergency medical facilities will be established in this area. Personnel may wear normal street clothes within this area. Eating, drinking, and smoking are permitted in this area.

8.2 SPILL CONTROL
Absorbent material for spill containment will be kept on-site, especially during any groundwater sampling. The absorbent material will also be present in the CRZ to contain any spills from the decontamination process.

8.3 BUDDY SYSTEM
The “Buddy System” will be used on-site to:
• Work inside the EZ
• Warn partners of an impending hazard
• Periodically check the integrity of partner’s PPE
• Provide aid in the case of injury, and notify the appropriate personnel of accidents.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 346 of 1214 Page 376 of 1692 Converse Project No. 24-41-114-02 16
Prior to working in the field, “buddies” will establish a time to communicate if either one is out of sight from the other person for an extended period. A way to communicate should also be agreed on prior to entry into the work area.

8.4 SITE SECURITY
Site security is necessary to:
• Prevent the exposure of unauthorized, unprotected people to Site hazards; • Prevent theft; and
• Avoid interference with safe working procedures.
• Personnel and vehicle entry will be restricted in established work zones. The responsibilities of personnel include:
• Limiting access to authorized personnel only. Requiring identification of all personnel requesting access to the work zones (i.e., SZ, CRZ, or EZ); • Ensuring that all visitors to the Site who will not be involved in specific work operations have a valid purpose for entering the Site and approval for access from the SHSO. The SHSO will ensure that visitors entering work zones have the appropriate training, and have read and signed the HASP;
• Requiring all personnel accessing the work zones to sign in and out; • Excluding unauthorized personnel from the Site. Advising unauthorized personnel attempting to gain access to the Site that they are trespassing and will be prosecuted for unauthorized entrance to the Site. Security personnel will make all reasonable efforts to record a description of the trespasser and their vehicle; • In the event of a fire, explosion, release of airborne contaminants, flood, or other emergency that requires the evacuation of personnel, security personnel will limit Site access to only those personnel authorized by the Site emergency response coordinator.

The SHSO will initiate a head count, review the sign-in log, and determine which personnel, if any, are not accounted for; and
• Keeping a daily security log including entry/exits log, vehicle log, results of security checks, and details of any security problems.

8.5 SAFE WORK PRACTICES
To maintain strong safety awareness and enforce safe procedures, the following personnel requirements and prohibitions will be established for the Site:
• The subject work area will be restricted to authorized visitors and personnel. These individuals will be required to attend a tailgate safety meeting upon entering the subject area during which they will be informed of the various work zones and facilities, the health and safety hazards associated with their assigned work activities, control measures, the care and use of personal protective equipment, emergency action plans, and other pertinent information. Tailgate safety meetings will be conducted on a daily basis at the beginning of each shift. Attendance rosters will be recorded and maintained by the PFS;
• All persons entering the Site will be required to identify themselves to the PFS. Persons who have not attended a tailgate safety meeting on that day will be required to do so with the SHSO or other authorized representative. Persons unfamiliar with the Site will Cudahy Park Renovation Project, Project # PRE-001 Document Control 347 of 1214 Page 377 of 1692 Converse Project No. 24-41-114-02 17
be informed of Site hazards and instructed to avoid contact with contaminated surfaces, soils, sample materials, or related equipment, and will be instructed to remain upwind from all active work areas. Eating, drinking, chewing gum or tobacco, smoking or any practice that increases the probability of hand-to-mouth transfer and ingestion of material is prohibited in the EZ and CRZ. Drinking water or equivalent fluids may occur in the CRZ at the discretion of the SHSO. Before wearing Level C PPE, personnel may drink fluids in the CRZ. They will also complete the decontamination procedures necessary to exit the EZ, remove their respiratory protection, remove all protective gloves, and wipe their hands and face with pre-moistened towelettes;
• Any skin contact with contaminated or potentially contaminated surfaces, samples, or equipment will be avoided;
• Site personnel will use the “Buddy System” when performing duties in the EZ and CRZ work zones. Communications between members will be maintained at all times. Visual contact will be maintained between buddy pairs at all times; • As appropriate, equipment will be bonded and grounded, and will be spark resistant; • A fire extinguisher will be available for use in the subject area during all working hours. If the travel distance to the extinguisher from any point in the area where work is in progress is greater than 50 feet (15.3 meters), then additional fire extinguishers will be furnished and strategically located so that the travel distance does not exceed 50 feet (15.3 meters);
• A portable emergency eyewash station will be located strategically in the work area. The eye wash station will be capable of flushing the eyes with copious amounts of water; • Upon leaving the CRZ, all persons will adhere to the decontamination procedures outlined in this HASP;
• Removal of materials from protective clothing or equipment by blowing, shaking, or any other means which may disperse contaminated materials into the air is prohibited; • Legible precautionary labels will be affixed to containers of raw materials, intermediate products, mixtures, waste debris, and contaminated PPE; • Contaminated PPE will not be removed from the Site until it has been cleaned or properly packaged or labeled;
• Hands will be thoroughly washed upon leaving contaminated or suspected contaminated areas before eating, drinking, or other such activity;
• All hazardous wastes, soil samples, and other contaminated materials which are removed from the subject Site will be accompanied by appropriate shipping papers; • A first-aid kit suitable for use at hazardous waste sites will be located in the SZ at each contamination reduction corridor;
• No running or horseplay;
• The required level of PPE must be worn by all on-site personnel; • No facial hair that interferes with a satisfactory fit of the mask-to-face seal is allowed on personnel required to wear respiratory protection;
• Medicine and alcohol can worsen the effects from exposure to toxic chemicals.

Prescribed drugs will not be taken by personnel on operations where the potential for absorption, inhalation, or ingestion of toxic substances exists, unless specifically approved by a qualified physician. Alcoholic beverage intake will not be allowed during breaks;
• Safety devices on equipment must be left intact and used as designed; and Cudahy Park Renovation Project, Project # PRE-001 Document Control 348 of 1214 Page 378 of 1692 Converse Project No. 24-41-114-02 18
• Equipment and tools will be kept clean and in good repair, and used only for their intended purpose.

8.6 STANDARD OPERATING PROCEDURES
Employees and subcontractors are expected to follow the standard operating procedures listed below while involved in work at the Site:
• Buddy System: A minimum of two (2) workers will be on the Site at all times during all operations. The buddy pair(s) will maintain visual or voice contact at all times. In addition, a minimum of one (1) person will remain in the SZ, at all times; • PPE: All persons entering the EZ will do so while wearing the PPE equipment documented in this HASP. Such individuals will be trained in the proper use, care and maintenance of this equipment, will have submitted to a physical examination by a licensed medical physician, and will have been deemed physically fit to wear such equipment. The user will inspect such equipment before donning. Donned gloves and boots will be taped to protective clothing to provide closure; • Emission control: Wet methods will be used to control emissions of volatile hydrocarbon or other gases and vapors, liquids, or particulate materials; and • Observance of Unanticipated Hazardous Materials: In the event, unanticipated hazardous material(s) are observed or symptoms of distress are experienced by workers, the SHSO will conduct an investigation. He/she may collect samples in order to ascertain the identity of the material(s).
• Symptoms of Distress: The SSO and each subcontractor field supervisor will periodically observe personnel for symptoms of distress. Indications of such adverse effects include:
-Changes in complexion, skin discoloration
-Signs of in-coordination
-Changes in demeanor, disposition
-Excessive salivation, papillary response
-Changes in speech patterns
-Nervousness or excitability
Field personnel are required to contact their field supervisor upon experiencing ill effects such as:
• Headache or dizziness
• Blurred vision
• Irritation to the eyes, mucous membranes, respiratory tract or skin • Heat stress
• Daily Shutdown: All mechanical equipment will be parked and/or stored in a safe location designated by the PM, PFS, or SHSO.
• Stop Work Orders: In the event work is performed contrary to the provisions of the specifications and/or approved work plans, or contrary to the conditions of any applicable permit or certificate, or if upon inspection, it is determined that continuation of authorized work is likely to endanger any person or public and/or private Site, then the work will be stopped by notice in writing served by the PM or any other authorized representative.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 349 of 1214 Page 379 of 1692 Converse Project No. 24-41-114-02 19

8.7 SANITATION
An adequate supply of potable water will be provided. Potable drinking water containers will be capable of being tightly closed and be equipped with a tap. The “common” drinking cup is prohibited. Adequate washing facilities for employees engaged in operations at the Site will be provided. The facilities will be in proximity to the work site and will be equipped to handle both sexes.

8.8 SITE COMMUNICATION
Successful communication between field teams and SZ personnel is essential. An internal communication system among on-site personnel and an external communication system between on-site and off-site personnel will be established.

8.8.1 Internal Communication System
The internal communication system will be used to relay health and safety information, communicate changes in work, maintain Site control, and alert personnel in case of emergencies. Verbal communications will be the primary method of routine communication.

8.8.2 External Communication System
The external communication system between on-site and off-site personnel is necessary to report to management, maintain contact with essential off-site personnel, and coordinate emergency response. Cellular telephones maintained in the SZ will be the primary means of external communication, and will be used to notify off-site emergency response agencies if incidents and to request assistance.

8.9 VISITOR CLEARANCES
Entry to hazardous areas will be limited to individuals who must work in those areas. Unofficial visitors must not be permitted to enter hazardous areas while work in those areas is in progress.

Official visitors should be discouraged from entering work areas, but may be allowed to enter only if they agree to abide by the provisions of this document, follow orders issued by the SSO, and sign a compliance agreement that they were informed of the potential dangers that could be encountered in the areas.

9.0 PERSONNEL PROTECTIVE EQUIPMENT
The purpose of PPE is to isolate or protect personnel from the chemical and physical hazards that may be encountered at the work site. A Site-specific PPE program has been developed.

The various components of this program are levels of protection, respirator care, PPE inspection, and levels of protection per task.

PPE and safety precautions will be appropriate to protect against the known and potential health hazards in the subject area. The protective equipment required has been selected based on the contaminant type, anticipated concentrations in the air, and known routes of entry into the body.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 350 of 1214 Page 380 of 1692 Converse Project No. 24-41-114-02 20

9.1 LEVELS OF PROTECTION
The levels of protection (LOP) required for the investigation of the source of communication will be continually evaluated as fieldwork progresses. It should be noted that there may be increases or decreases in the LOP. The following levels of protection have been defined based on a review of work site histories and tasks to be performed.

9.1.1 Level D
United States Environmental Protection Agency (USEPA) Level D personnel protective equipment for all personnel entering the work area, unless the SHSO decides to upgrade the level of protective equipment to be used. Level D consists of the following:
• Work clothes
• Construction quality boots with steel toe and shank
• Inner polyvinyl chloride surgical or latex gloves
• Hard hats
• Safety glasses and hearing protection.

At a minimum, the following PPE will be discarded and replaced daily:
• Inner polyvinyl chloride surgical or latex gloves
• Outer gloves
New outer gloves should be used for each sample.

9.1.2 Modified Level D
Modified Level D personnel protective equipment may be required by the SHSO if monitoring data or the tasks to be performed suggests that personnel entering the work area need additional protection. Modified Level D consists of the following:
• Uncoated Tyvek
• During intrusive activities, Tyvek sleeves will be worn over the cuff of protective gloves and Tyvek legs will be worn over the upper portion of disposable boot covers. Tape will be used to seal the joints between Tyvek, protective gloves, and boot covers
• Protective disposable gloves (inner latex, outer nitrile or butyl) • Chemical-resistant outer gloves
• Boots (PVC, neoprene or other chemically resistive material) with steel toe and shank
• Splash-resistant goggles will be worn if splashing may occur • Hard hats.

9.1.3 Level C

• Full- or half-face respirators and NIOSH/OSHA approved cartridges sealed in a plastic bag and ready for immediate donning. The cartridges to be used will be HEPA organic vapor cartridges with dust mist pre-filter.

9.1.4 Level B
Level B is used when a high level of respiratory protection is required. This involves atmospheres with Immediately Dangerous to Life or Health (IDLH) concentrations of specific substances that do not represent a skin hazard or atmospheres containing less than 19.5% oxygen. Level B gear consists of the following:
• Pressure-demand, full-face, self-contained breathing apparatus (SCBA) or pressure-demand supplied-air respirator with escape SCBA • Chemically-resistant Tyvek suits (wet soil)
• Uncoated Tyvek suits (dry soil)
• Chemically-resistant inner and outer gloves
• Chemically-resistant steel-toed rubber boots
• Hard hat
• Hearing protection
• Two-way radio communications.

Level B personal protective equipment will not be available on-site. Should the SHSO determine that Level B protection is required; the CHSO will be contacted to make arrangements for a Certified Industrial Hygienist to evaluate the health and safety requirements at the Site and prepare a more detailed HASP.

9.2 RESPIRATOR CARE
Each individual is responsible for inspecting and maintaining his or her own respirator. Before being taken into the field, all respirators will be inspected, cartridges (if used) installed, a positive and negative pressure check conducted, and the entire respirator assembly will be sealed in a plastic bag. After the respirator is used, the following cleaning procedures will be used:
• Cartridges for air-purifying respirators will be removed and disposed of as contaminated PPE
• The respirator face piece interior and exterior will be wiped down with premoistened towelettes, such as baby wipes, and subsequently sealed in a plastic bag for transport to the respirator cleaning station at the personal decontamination facility
• After a respirator has been cleaned and rinsed, it will be patted dry and a clean towel and stored.

9.3 PPE INSPECTION
PPE inspection will be done before use, during use, and after use. The following will be inspected during the course of the work activities at the Site.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 352 of 1214 Page 382 of 1692 Converse Project No. 24-41-114-02 22

9.3.1 Clothing
Before use:
• Determine that the LOP is correct for the specific task at hand by consulting with the SSO.
• Visually inspect for:
- Imperfect seams

Also, make sure that the canisters or cartridges have not been previously used.

After use, make sure that respirators have been adequately cleaned.

9.4 LEVEL OF PPE PROTECTION
The work being performed will be conducted in Level D or modified Level D. Levels of protection will be upgraded in accordance with action levels provided in Table 2: Response Level and Action. PPE ensembles have been selected to ensure a level of protection greater than the minimum required to protect employees from anticipated hazards. The HASP will further assess the workplace hazards and ensure that the proper PPE ensemble is provided and worn during work activities.

9.5 EQUIPMENT REQUIRED TO BE AVAILABLE ON-SITE
Items required on-site include:
• First-aid kit with eye wash
Cudahy Park Renovation Project, Project # PRE-001 Document Control 353 of 1214 Page 383 of 1692 Converse Project No. 24-41-114-02 23
• Fire extinguisher
• Construction tape and barriers to delineate work zone • Decontamination equipment
• NO SMOKING signs
• A vehicle must be kept on-site when personnel are working for the transport of slightly injured personnel to the hospital (severely injured personnel MUST be transported by paramedics).

10.0 DECONTAMINATION METHODS
Decontamination procedures will be implemented to protect personnel from hazardous substances that may contaminate and/or eventually permeate protective clothing, respiratory protective equipment, tools, vehicles, and other equipment used on-site; to protect all Site personnel by minimizing the transfer of harmful materials into clean areas; to prevent mixing of incompatible chemicals; and to protect the community by preventing uncontrolled transportation of contaminants from the Site. Personnel exiting the EZ will pass through the CRZ, where protective gear will be cleaned and/or discarded. There will be one (1) CRZ per EZ. The particular location of the CRZ will be determined during the initiation of Site activities.

10.1 PERSONNEL DECONTAMINATION
Personnel decontamination facilities will be supplied with a potable water supply. All personnel leaving the EZ must exit through the CRZ and perform appropriate decontamination procedures to prevent the transfer of contaminated materials into clean areas. The types of contaminants that they may have contacted and their function in the CRZ should determine the extent of their decontamination.

The decontamination process consists of a series of procedures performed in a specific sequence, depending on the level of PPE worn and Site contaminants present. Before the start of work activities, the number and layout of decontamination stations will be determined. To prevent cross-contamination, each procedure will be performed at a separate station, and stations will be arranged in order of decreasing contamination. In the event that Level C or B equipment is used, the following procedures will be instituted for decontamination all articles leaving the EZ and CRZ to prevent or reduce the physical transfer of contaminants by people and/or equipment from the subject area.

PERSONNEL EXITING EZ:
• If the worker is heavily contaminated, water will be used to remove contamination prior to entering the CRZ. Water will be contained in a bucket or tub • Deposit used equipment in the EZ or on tables in the CRZ for subsequent decontamination
• Scrub outer boot covers or polyvinyl chloride (PVC) overboots and outer gloves with decontamination solution or detergent and water
• If gross contamination is evident, remove contamination, to the extent practicable, from disposable suit and/or tank using disposable wipes or towels, with assistance from CRZ technician
• Remove tape around boots and gloves. Remove outer boot covers or PVC over boots and outer gloves. Discard tape, boot covers, and outer gloves in appropriate container Cudahy Park Renovation Project, Project # PRE-001 Document Control 354 of 1214 Page 384 of 1692 Converse Project No. 24-41-114-02 24
• Remove inner gloves and discard in appropriate container • Thoroughly wash hands and face
• All PPE, including respirator, protective clothing and boots, will be removed and placed in appropriately marked containers, for disposal or for decontamination (boots and respirator minus cartridges) as the individual steps from the CRZ to the SZ • Used boots, respirators, and other reusable personal protective equipment will be dismantled (if possible), decontaminated with mild detergent and warm tap water, and rinsed with clean tap water in the CRZ
• The spent solutions, brushes, and the like will, until shown otherwise, be considered contaminated and so treated
• Workers/visitors will be required to wash thoroughly with soap and water prior to leaving the Site and will be instructed to remove work clothes and shower as soon as possible thereafter.

10.2 EQUIPMENT DECONTAMINATION
Vehicles and equipment will be decontaminated before exiting the EZ. People and/or equipment from the subject area will institute the following procedures for decontaminating all vehicles and equipment leaving the EZ and CRZ to prevent or reduce the physical transfer of contaminants:
• An equipment decontamination pad or area will be designated for cleaning large equipment utilized during work activities
• All sampling devices will be decontaminated by scrubbing or wiping a decontamination solution and water on the device
• Tools that are difficult to decontaminate will be kept in the EZ and handled only by workers using the appropriate PPE
• Respirators will be decontaminated and sanitized before being reused • Following decontamination of equipment using steam cleaning, a final steam/water rinse will be applied
• The spent solutions, brushes, and the like will, until shown otherwise, be considered contaminated and so treated
• Wash materials will be disposed of properly
• All porous equipment, which is believed to be contaminated, will be disposed of as hazardous waste.

10.3 EMERGENCY DECONTAMINATION
During emergency situations, decontamination will be performed to the maximum extent possible without compromising medical attention to the victim. If decontamination may aggravate or cause more serious health effects, or if injuries are life threatening, prompt life saving, first aid and medical treatment should be administered without decontamination or concurrently with it. Outer garments can be removed (depending on the weather) if it does not delay or interfere with medical treatment, or aggravate the problem. Respirators and backpack assemblies must always be removed. If outer garments cannot be safely removed, the victim should be wrapped in plastic, rubber, or blankets to minimize contamination of emergency transport vehicles and medical personnel. Whenever possible, Site personnel should accompany the contaminated victim to the medical facility to advise of matters involving decontamination.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 355 of 1214 Page 385 of 1692 Converse Project No. 24-41-114-02 25

10.4 EQUIPMENT FOR DECONTAMINATION OF PERSONNEL, PPE, AND HEAVY

EQUIPMENT
The following is a list of equipment needed to conduct proper decontamination of personnel, PPE, and equipment:
• Drop cloths of plastic or other suitable materials on which heavily contaminated equipment and other protective clothing may be deposited • Collection containers, such as drums or suitably lined trash cans for storing disposable clothing and heavily contaminated personal protective clothing or equipment that must be discarded
• Lined box with absorbents for wiping or rinsing off gross contamination and liquid contaminants
• Galvanized tubs, stock tanks, or children’s wading pools to hold wash and rinse solution.

The tubs should be large enough for a worker to place a booted foot inside • Appropriate wash solutions to wash off and reduce hazards associated with the contaminants
• Long-handled, soft-bristled brushes to scrub contaminants off PPE and for general exterior cleaning of heavy equipment
• Paper or cloth towels for drying protective clothing and equipment • Metal or plastic drums for contaminated wash and rinse solutions • Plastic sheeting, sealed pads with drains, or other appropriate methods for containing and collecting contaminated wash and rinse solutions
• Soap or wash solutions, washcloths, and towels for personnel.

11.0 EMERGENCY RESPONSE PROCEDURES
This Emergency Response/Contingency Plan (ERP) has been developed to include instruction and procedures for personnel evacuation and procedures for medical emergencies that may occur during the project. All personnel emergency conditions require actions conducted in a manner that minimizes health and safety risks. All on-site personnel must be familiar with the ERP. Additions to the ERP will be incorporated into this HASP by addendum. All aspects of the plan will be addressed as part of the Site-specific health and safety training required for all personnel.

11.1 RESPONSIBILITIES

11.1.1 Corporate Health and Safety Officer
The CHSO, or designee, will oversee the development and approval of the ERP and perform audits to ensure that the ERP is in effect and that all pre-emergency requirements are met. The CHSO will act as a liaison to applicable regulatory agencies and notify OSHA of reportable accidents or fatalities.

All information is to be communicated to the Emergency Coordinator. All media and public inquires are to be directed to the Emergency Coordinator.

11.2 POTENTIAL EMERGENCIES
The activities, layout, and hazards of the Site have been evaluated to determine anticipated potential emergencies. Five (5) categories of emergencies have been identified. The list will be revised in the event on-site conditions or operations warrant. The ERP will be updated in case of a revision or addition to the list. Anticipated emergencies include:

Cudahy Park Renovation Project, Project # PRE-001 Document Control 357 of 1214 Page 387 of 1692 Converse Project No. 24-41-114-02 27
• Injury or illness
• Fire
• Explosion
• Spill/environmental release
• Natural disaster/hazard.

At this Site, personnel accidents requiring first aid, potential fires, and potential exposure to soil with COCs are emergencies that may arise.

11.3 PUBLIC RESPONSE AGENCIES
Contact between Site personnel and local emergency services will assist in developing a good working relationship and provide an opportunity for the development of effective, overlapping emergency plans. The Emergency Coordinator will contact the local hospital before beginning work on the Site. The nature and duration of work, types of COCs and the potential emergency conditions will be discussed.

11.4 EMERGENCY CONDITIONS
Whenever there is an emergency at the Site, the following steps will be taken:
• An immediate report of the emergency will be made to the PM and PFS • The emergency will be assessed by the PFS and identify:
• The name, location, and telephone numbers of the appropriate agencies • The nature of the emergency
• Hazardous conditions (fire, explosion, etc.)
• The amount of material involved or released
• The extent to which evacuation should occur
• The PFS will notify all personnel on-site and activate the appropriate response • All work will be stopped and evacuation initiated if appropriate • The PFS will notify the following as necessary:

Should the emergency draw the attention of the public, all inquiries are to be directed to the PFS.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 358 of 1214 Page 388 of 1692 Converse Project No. 24-41-114-02 28

11.5 EMERGENCY EQUIPMENT
In addition to equipment that is to be used only in the event of an emergency, other equipment that may be used in the event of an emergency also may be used as part of regular operations, this may include PPE, telephones, etc. The following emergency equipment will be maintained at the first-aid station:
• Fire extinguisher
• Cell phone
• First-aid kit
• Eye wash solution.

11.6 ON-SITE PERSONNEL INJURY/ILLNESS
First aid will be administered on-site as necessary. Personnel requiring medical attention will be transported or emergency medical services will be contacted to respond. The medical data sheet will accompany the injured person. The route to the hospital is shown on Figure 2. This map will be posted at the first-aid station and is to be taken with the driver of the injured individual. The hospital will be notified of the impending arrival and provided with pertinent information while the injured individual is being transported.

Basic first aid procedures must be followed in the event a person working on-site is injured.

Depending on the severity of the injury, emergency medical response may be sought. If the person can be moved, they will be taken to the edge of the work area where emergency first aid can be administered. If necessary, transportation to the local emergency medical facility will be provided.

If the injury to on-site personnel involves chemical exposure, the following first-aid steps must be taken immediately:
• Eye Exposure – If foreign material (liquid or solid) gets into the eyes, wash eyes immediately for at least 15 minutes using water and lifting the lower and upper lids occasionally. Obtain medical attention immediately.
• Skin Exposure – Wash skin immediately with water. Obtain medical attention immediately.
• Inhalation – If a person has inhaled a large amount of organic vapor, dust, etc., move them to fresh air at once. Obtain medical attention immediately. If breathing has stopped, appropriately trained personnel and/or medical personnel should perform cardiopulmonary resuscitation (CPR). Keep the person warm and comfortable. • Ingestion – If liquid or solid is swallowed, obtain medical attention immediately. The Poison Control Center also must be consulted.

The SSO must inform the PM of any injury/accident and a written report of the accident, its causes and consequences must be submitted to the client within 48 hours of the incident.

11.6.1 Temperature Related Problems
First aid for all forms of heat stress includes cooling the body. This may involve removing PPE and moving the person to a cooler environment to rest.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 359 of 1214 Page 389 of 1692 Converse Project No. 24-41-114-02 29

11.6.2 Emergency Decontamination
In case of a medical emergency, gross decontamination procedures will be implemented and the person transported to the nearest medical facility. If a life threatening injury occurs and the injured person cannot be decontaminated without causing additional injuries, every effort will be made to ensure exposure of others to potential COCs is minimized. The medical facility will be notified of the potential COCs present and the exposure prevention measures that can be employed during treatment.

Decontamination measures for emergencies will be based on the toxicity of the COCs on-site and the immediacy of the emergency.

11.6.3 Fire
The Consultant will not respond to any fire that is larger than is able to be handled by the on-site portable fire extinguishers. Any fire too large to be extinguished by the portable extinguishers will be reported immediately to the local fire department by dialing 911.

There are three (3) basic ways to extinguish a fire:
• Take away its air
• Take away its fuel
• Cool the fire.

To put out a fire:
• Put it out with a fire extinguisher, water or other liquid (e.g., coffee) • Move all flammable materials away from the fire
• Smother the fire with a coat or other heavy, if possible wet, object.

To use a fire extinguisher:

1. Pick the extinguisher up by the handle.

2. Pull the ring at the top to release the safety pin

3. Keep the extinguisher upright, aim at the base of the fire, and squeeze the handle.

No individual should attempt to put out a fire unless they are sure they are able to do it.

SUMMON HELP IMMEDIATELY IF YOU THINK YOU ARE UNABLE TO PUT IT OUT! The fire extinguishers at the Site are multi-purpose dry chemical (ABC). These types of extinguishers are effective on ordinary combustibles, flammable liquids, and electrical equipment. The effective range is approximately five (5) to 15 feet. The contents will be discharged in eight (8) to 25 seconds.

The first five (5) minutes are the most critical in putting out a fire. It is crucial that the fire department be notified as soon as possible when a fire is discovered. Do not hesitate to report small fires. The fire can spread and become a threat to everyone’s safety.

Most fire related deaths occur from poisonous gases, smoke, and panic. Few deaths are the result of being burned. Panic is the most common cause of death in a fire situation. In the event of a fire, know what to do and DO NOT PANIC.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 360 of 1214 Page 390 of 1692 Converse Project No. 24-41-114-02 30
If a fire occurs while working within a building, evacuate by the building by doing the following:

1. Listen to the instructions of the PFS

2. Walk to the nearest exit unless instructed otherwise

3. To prevent a bottleneck, move to the assembly area

4. Await further instructions.

11.6.4 Explosion
An explosion can be the most difficult emergency to deal with. Reasons include trauma, death, fire, unstable structures, secondary explosions, toxic clouds, and destruction of emergency equipment. The following, measures, and backup systems may be required:
• Initiate evacuation procedures
• Notify appropriate response agencies (fire, police, etc.) • Assess situation – are secondary emergencies occurring or about to occur? • Turn off or remove sources of explosives
• Attend to the injured
• Check for exposed live utilities
• Initiate spill response measures (if necessary).

11.7 SPILLS/ENVIRONMENTAL RELEASE
The first responder on the scene is responsible for spill containment until additional help arrives. Upon arriving at the scene, the individual will determine:
• The location of the spill
• If liquid, direction of flow
• If possible the identity of the leaking material
• Potential hazards to responders.

If the leaking material is not completely characterized, the maximum PPE should be worn and only experienced individuals should enter the area.

Spilled liquids may be contained by the construction of dikes, diversion of spills to specific areas, inlet blockage, or solidification. Special attention should be given to quickly preventing spills from leaving the confines of the Site and entering the public right-of-way or sewer/storm drain system.

Equipment or supplies for controlling spills may include the following:
• Sandbags
• Absorbent socks, pillows, etc.
• Dry granular absorbent
• Salvage pumps
• Drums
• Plastic sheets, tarps, salvage covers, etc.
• Absorbent booms
• Barrier booms.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 361 of 1214 Page 391 of 1692 Converse Project No. 24-41-114-02 31
In addition to containing the spilled materials, the source of the spill must also be controlled.

For leaking containers (e.g., drums, small tanks, etc.) the material should be transferred to vessels capable of storing the liquids. Used materials such as absorbent pads/booms/sheets or granular absorbents are to be collected in the appropriate storage containers until they can be disposed of properly.

Once containment of the spill has occurred, and/or sufficient help has arrived, the PM must be notified. The PM then will notify the appropriate parties (e.g., DTSC, USEPA, local fire department, etc.) to report the release.

11.8 NATURAL HAZARDS
In the event of a natural disaster, work will be halted and the Site secured as possible.

Restoration after the event will include a recheck of all operating systems, containment and cleanup of spills and resumption of operations.

11.9 BOMB THREATS/CIVIL COMMOTION
Bomb threats, vandalism, arson, riots, and assaults are almost impossible to anticipate.

However, using common sense and implementing security measures can prevent or reduce their impact and proper response can help control further loss.

Information Advisory
Clean Imported Fill
Cudahy Park Renovation Project, Project # PRE-001 Document Control 366 of 1214 Page 396 of 1692 Executive Summary
This fact sheet has been prepared to ensure that inappropriate fill material is not introduced onto sensitive land use properties under the oversight of the DTSC or applicable regulatory authorities. Sensitive land use properties include those that contain facilities such as hospitals, homes, day care centers, and schools. This document only focuses on human health concerns and ecological issues are not addressed.

It identifies those types of land use activities that may be appropriate when determining whether a site may be used as a fill material source area. It also provides guidelines for the appropriate types of analyses that should be performed relative to the former land use, and for the number of samples that should be collected and analyzed based on the estimated volume of fill material that will need to be used.

The information provided in this fact sheet is not regulatory in nature, rather is to be used as a guide, and in most situations the final decision as to the acceptability of fill material for a sensitive land use property is made on a case-by-case basis by the appropriate regulatory agency.

Introduction
The use of imported fill material has recently come under scrutiny because of the instances where contaminated soil has been brought onto an otherwise clean site. However, there are currently no established standards in the statutes or regulations that address environmental requirements for imported fill material.

Therefore, the California Environmental Protection Agency, Department of Toxic Substances Control (DTSC) has prepared this fact sheet to identify procedures that can be used to minimize the possibility of introducing contaminated soil onto a site that requires imported fill material. Such sites include those that are undergoing site remediation, corrective action, and closure activities overseen by DTSC or the appropriate regulatory agency. These procedures may also apply to construction projects that will result in sensitive land uses. The intent of this fact sheet is to protect people who live on or otherwise use a sensitive land use property. By using this fact sheet as a guide, the reader will minimize the chance of introducing fill material that may result in potential risk to human health or the environment at some future time.

Cudahy Park Renovation Project, Project # PRE-001 Document Control 367 of 1214 Page 397 of 1692 2 Overview
Both natural and manmade fill materials are used
for a variety of purposes. Fill material properties are commonly controlled to meet the necessary site specific engineering specifications. Because most sites requiring fill material are located in or near urban
areas, the fill materials are often obtained from construction projects that generate an excess of soil, and from demolition debris (asphalt, broken concrete,
etc.). However, materials from those types of sites
may or may not be appropriate, depending on the
proposed use of the fill, and the quality of the assessment and/or mitigation measures, if necessary.

Therefore, unless material from construction
projects can be demonstrated to be free of contamiPotential Contaminants Based on the Fill Source Area Fill Source:

nation and/or appropriate for the proposed use, the
use of that material as fill should be avoided.

Selecting Fill Material
In general, the fill source area should be located in
nonindustrial areas, and not from sites undergoing
an environmental cleanup. Nonindustrial sites include those that were previously undeveloped, or used solely for residential or agricultural purposes.

If the source is from an agricultural area, care should be taken to insure that the fill does not include
former agricultural waste process byproducts such
as manure or other decomposed organic material.

Undesirable sources of fill material include industrial and/or commercial sites where hazardous ma- *The recommended analyses should be performed in accordance with USEPA SW-846 methods (1996).

terials were used, handled or stored as part of the
business operations, or unpaved parking areas where
petroleum hydrocarbons could have been spilled or
leaked into the soil. Undesirable commercial sites
include former gasoline service stations, retail strip
malls that contained dry cleaners or photographic
processing facilities, paint stores, auto repair and/or painting facilities. Undesirable industrial facilities
include metal processing shops, manufacturing facilities, aerospace facilities, oil refineries, waste treatment plants, etc. Alternatives to using fill from construction sites include the use of fill material obtained from a commercial supplier of fill material or from soil pits in rural or suburban areas. However, care should be taken to ensure that those materials are also uncontaminated.

Documentation and Analysis
In order to minimize the potential of introducing
contaminated fill material onto a site, it is necessary to verify through documentation that the fill source
is appropriate and/or to have the fill material analyzed for potential contaminants based on the location and history of the source area. Fill documentation should include detailed information on the previous use of the land from where the fill is taken, whether an environmental site assessment was performed and its findings, and the results of any testing performed. It is recommended that any such documentation should be signed by an appropriately licensed (CA-registered) individual. If such documentation is not available or is inadequate,
samples of the fill material should be chemically analyzed. Analysis of the fill material should be based on the source of the fill and knowledge of the prior
land use.

Detectable amounts of compounds of concern
within the fill material should be evaluated for risk
in accordance with the DTSC Preliminary Endangerment Assessment (PEA) Guidance Manual. If Cudahy Park Renovation Project, Project # PRE-001 Document Control 369 of 1214 Page 399 of 1692 4 metal analyses are performed, only those metals
(CAM 17 / Title 22) to which risk levels have been
assigned need to be evaluated. At present, the
DTSC is working to establish California Screening Levels (CSL) to determine whether some compounds of concern pose a risk. Until such time as these CSL values are established, DTSC recommends that the DTSC PEA Guidance Manual or an equivalent process be referenced. This guidance may include the Regional Water Quality Control Board’s (RWQCB) guidelines for reuse
of non-hazardous petroleum hydrocarbon contaminated soil as applied to Total Petroleum Hydrocarbons (TPH) only. The RWQCB guidelines should not be used for volatile organic compounds
(VOCs) or semi-volatile organic compounds
(SVOCS). In addition, a standard laboratory data
package, including a summary of the QA/QC
(Quality Assurance/Quality Control) sample results should also accompany all analytical reports.

When possible, representative samples should be collected at the borrow area while the potential fill material is still in place, and analyzed prior to removal from the borrow area. In addition to performing
the appropriate analyses of the fill material, an appropriate number of samples should also be determined based on the approximate volume or area of soil to be used as fill material. The table above can
be used as a guide to determine the number of
samples needed to adequately characterize the fill
material when sampled at the borrow site.

Alternative Sampling
A Phase I or PEA may be conducted prior to sampling to determine whether the borrow area may have been impacted by previous activities on the
property. After the property has been evaluated, any
sampling that may be required can be determined
during a meeting with DTSC or appropriate regulatory agency. However, if it is not possible to analyze the fill material at the borrow area or determine that it is appropriate for use via a Phase I or PEA, it is recommended that one (1) sample per
truckload be collected and analyzed for all compounds of concern to ensure that the imported soil is uncontaminated and acceptable. (See chart on
Potential Contaminants Based on the Fill Source
Area for appropriate analyses). This sampling frequency may be modified upon consultation with the DTSC or appropriate regulatory agency if all of
the fill material is derived from a common borrow
area. However, fill material that is not characterized
at the borrow area will need to be stockpiled either
on or off-site until the analyses have been completed.

In addition, should contaminants exceeding acceptance criteria be identified in the stockpiled fill material, that material will be deemed unacceptable
and new fill material will need to be obtained,
sampled and analyzed. Therefore, the DTSC recommends that all sampling and analyses should be completed prior to delivery to the site to ensure the
soil is free of contamination, and to eliminate unnecessary transportation charges for unacceptable fill material.

Composite sampling for fill material characterization may or may not be appropriate, depending on quality and homogeneity of source/borrow area, and
compounds of concern. Compositing samples for
volatile and semivolatile constituents is not acceptable. Composite sampling for heavy metals, pesticides, herbicides or PAH’s from unanalyzed stockpiled soil is also unacceptable, unless it is stockpiled at the borrow area and originates from the same
source area. In addition, if samples are composited,
they should be from the same soil layer, and not
from different soil layers.

When very large volumes of fill material are anticipated, or when larger areas are being considered as borrow areas, the DTSC recommends that a Phase
I or PEA be conducted on the area to ensure that
the borrow area has not been impacted by previous
activities on the property. After the property has
been evaluated, any sampling that may be required
can be determined during a meeting with the
DTSC.
