1.0 INTRODUCTION

This Community Health and Safety Plan (CHASP) has been prepared by Weaver Consultants Group of California, LLC. (WCG), the successor in interest to Avocet Environmental, Inc.

(Avocet)1, to cover environmental services related to the characterization and stabilization of illegal fill material imported onto part of Assessor’s Parcel Number (APN) 646-040-020 in Otay Mesa, California (the property or site) The property is owned by the California Department of Corrections and Rehabilitation (CDCR) and is one of several parcels developed with the Richard J.

Donovan Correctional Facility (RJ Donovan Facility). The property location and the approximate limits of inert fill material are shown in Figure 1. A larger-scale plan of the inert fill area and vicinity is presented in Figure 2. For the purpose of this CHASP, the area of focus is within the boundary of where the illegal dumping appears to have occurred (Figure 2). This area, referred to as the dump site, is also referred to as the investigation area based on context.

1.1 BACKGROUND INFORMATION

On December 31, 2015, the San Diego County Department of Environmental Health, Solid Waste Local Enforcement Agency (LEA) received a complaint referral from the County of San Diego Watershed Protection Program that a neighboring property (referred to as the Ingalls property) was operating an unauthorized mobile home park and that imported fill had been illegally dumped on the south-adjoining CDCR property. The LEA investigated the complaint on January 6 and 25, 2016 and, based on its findings, issued Notice and Order No. 2016-02 to CDCR for two violations, one for the disposal of solid waste without having a solid waste facility permit, and the second for operating a solid waste facility without a solid waste facility permit. Pursuant to these violations, Avocet assessed the inert fill site in accordance with a November 2016 work plan approved by the LEA. Avocet conducted the assessment in April 2017, which was documented in a report dated July 12, 2017. In brief, the assessment involved 33 trenches, most of which were excavated through the entire thickness of the inert fill until underlying, native soil was encountered. Avocet identified five different types of imported fill materials, fill types Af1 through Af5. The locations of the trenches and the limits of the different fill types are shown in Figure 3, and a cross section through the filled area is presented in Figure 4. Representative samples of the fill materials were analyzed for total petroleum hydrocarbons (TPH), volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), metals, polychlorinated biphenyls, asbestos, and pH;

however, the reported concentrations, where detectable at all, were of minor concern. Based on the assessment, Avocet estimated that the inert fill covers approximately 4.8 acres, with a volume of approximately 44,000 cubic yards.

CDCR’s working assumption prior to Avocet’s July 12, 2017 assessment report had been that it would remove the inert fill and dispose of it in a local landfill. However, a preliminary cost estimate based on the larger than expected fill volume indicated this option would cost in the order of $4 million. On August 30, 2017, the LEA, CDCR, and Avocet met to discuss the results of the

Bid Number C5613351-D Exhibit A-3 http://www.wcgrp.com/ http://www.wcgrp.com/ assessment and options for the disposition of the fill material, one of which was to leave it in place.

At this meeting, the LEA concurred that the fill essentially is inert and uncontaminated and, with the possible exception of the concrete/asphalt debris on the surface of a portion of the fill area, could probably be left in place. As County of San Diego departments other than the LEA would need to be consulted about leaving the fill in place, including possible permitting requirements, the LEA requested that CDCR submit a conceptual plan for managing the inert fill.

On November 27, 2017, Avocet submitted a conceptual plan that proposed leaving most of the inert fill onsite. The goal of the conceptual plan was to remove, to the extent practical, Fill Types Af1 and Af5 and stabilize Fill Types Af2, Af3, and Af4 in such a way as to minimize erosion and the visual impact of leaving them in place. The conceptual plan was approved by the LEA in a letter dated March 21, 2018. In this letter, the LEA also requested that samples of the native soil beneath Trenches T4-A and T5-A be collected and analyzed due to the detections of TPH and polynuclear hydrocarbons (PAHs) in soil samples collected from the trenches.

After approving the conceptual plan in 2018, the LEA indicated that CDCR should request oversight from the California Environmental Protection Agency (CalEPA), Site Designation Committee (SDC). CDCR submitted the request on August 7, 2018, but on October 12, 2018, the SDC responded via email that based on Avocet’s July 12, 2017 assessment report, the inert fill site did not appear to be a “hazardous material release site,” as defined by Health and Safety Code, Division 20, Chapter 6.65, Section 25260. As such, SDC indicated it had no jurisdiction and recommended that CDCR withdraw its request for CalEPA oversight, which CDCR did, and oversight remained with the LEA.

On February 13, 2020, Avocet submitted grading plans and specifications to the LEA based on the conceptual plan. Following this submittal, the LEA informed CDCR that oversight was being transferred to San Diego County Department of Environmental Health (SDCoDEH). After SDCoDEH received the project from the LEA, it was suggested that CDCR enroll in SDCoDEH’s Voluntary Assistance Program (VAP). Following CDCR’s enrollment in the VAP, CDCR and SDCoDEH had several conference calls to bring SDCoDEH up to date on the project. Following a conference call with County of San Diego, Planning and Development Services Section on November 5, 2021, it was determined that no other permits were needed from the County of San Diego and that CDCR could proceed with implementing the conceptual plan as detailed in the grading plans and specifications.

In a May 10, 2022, report, Avocet presented the results from Borings SB-1 and SB-2, which were completed on April 1, 2022. The borings were completed to facilitate the collection of native soil samples beneath the fill at Trenches T4-A and T5-A. The soil samples were analyzed for TPH and SVOCs, with neither soil sample containing detectable concentrations.

1.2 PLAN PURPOSE AND OBJECTIVES

This CHASP has been prepared at the request of the LEA to ensure that public health is protected during the removal of concrete debris and slope stabilization of the inert fill materials on the property. The scope of work involves the removal, to the extent practical, of crushed concrete (Fill

Types Af1 and Af5) for offsite recycling or disposal while minimizing disturbance of the other fill types and the surrounding and underlying native materials. After removing the crushed concrete, the remaining inert fill soil (Fill Types Af2, Af3, and Af4) will be stabilized and recontoured, as needed, to minimize particulates in stormwater runoff and to match, to the extent practical, the surrounding undisturbed ground surface. Based on the findings of the investigation conducted by Avocet and consistent with SDC’s October 18, 2018 email to CDCR, the area in which inert fill has been illegally deposited is not a “hazardous material site,” based on contaminant concentrations, where detectable, being negligible. As such, site-specific contaminants of potential concern are limited to benzo(a)pyrene and silica dust; however, the inert fill will be closely monitored for indications of foreign objects (i.e., construction debris and/or non-soil inert waste) and contamination during the planned grading and stabilization activities. Fill suspected of being impacted will be segregated and characterized to determine whether it can be reused onsite, i.e., incorporated into the stabilized fill, or must be transported offsite for disposal. Similarly, any buried construction debris and/or non-soil inert waste will be removed, segregated, and disposed of offsite, where possible. Regarding the community (i.e., offsite receptors), the principal hazards associated with the work involve a short-term increase in vehicular traffic and potential exposure to dust containing silica or possibly unknown substances. CDCR’s chosen excavation contractor will be providing all equipment and personnel for the planned concrete debris removal and slope stabilization.

Before conducting work, the boundary of the inert fill area will be delineated with stakes, delineators, caution tape, and similar. The delineated area will be considered the “work area” and will be accessed only via the existing upper and lower access roads. Earthmoving and/or other equipment will not be allowed to operate outside of the delineated work area to preserve the existing desert patina and native plant species. To protect the unnamed water course to the northeast (Figure 3) a silt fence will be erected or other stormwater “best management practices” (BMPs) will be deployed along the downslope side of the work area. The removal of concrete debris will be accomplished using an excavator to draw crushed concrete towards itself from the perimeter of the covered area and load it into trucks. Alternately, a backhoe may be used to collect and load the crushed concrete into trucks. As previously noted, earthmoving and/or other equipment will not be allowed to operate outside of the delineated work area, and trucks will be allowed to enter via the existing upper and lower access roads only. Considering dust generation, preventative measures implemented during field activities will include wetting or misting exposed “soil” surfaces, as necessary, with potable water prior to soil disturbance; wetting or misting disturbed soil, as necessary, during earth moving tasks; and handling disturbed soil in such a way as to minimize the potential generation of dust.

After removing concrete debris, the remaining inert fill soil will be stabilized by compaction and the elimination of unnaturally steep slopes. The regraded surface will be indented by the earthmoving equipment with track marks perpendicular to the slope. This form of recontouring will increase or decrease the thickness of the inert fill in some areas; however, the area covered by inert fill will not be increased. As a final measure, the fill area will be hydroseeded with a native seed mix to further minimize and control runoff. The silt fence and/or other stormwater BMPs

TBB

California Department of Corrections and Rehabilitation (CDCR) Community Health and Safety Plan

Bid Number C5613351-D will remain in place on the downslope side of the fill area to protect the unnamed water course until the vegetation becomes established.

If any impacted soil, buried construction debris, and/or non-soil inert waste is encountered and cannot be utilized onsite, it will be transported offsite for treatment or disposal. Impacted soil will be wetted and loaded into trucks from minimal “drop heights” to reduce the generation of dust.

Prior to leaving the site, impacted soil in trucks will be covered with tarpaulins or similar and trucks and bins will be thoroughly inspected, particularly truck wheels and undercarriages, to ensure there is no loose dirt that may fall off onto public streets. Public streets near the site used by trucks transporting impacted soil offsite will be inspected on a daily basis for debris and/or dust accumulations and swept, as necessary.

This CHASP has been prepared to further assist in providing adequate protection of human and public health during the removal of concrete debris and slope stabilization of inert fill material at the site. The primary purpose of this CHASP is to promote a safe work environment relative to the public by reducing the potential for community exposures to potential hazards and nuisances from the work required for the project. Although this CHASP has been prepared as a “stand-alone” document pertaining to community health and safety, it is noted that a site-specific Health and Safety Plan (HASP) has also been prepared by WCG and pertains to health and safety for onsite workers.

2.0 PURPOSE AND SAFETY ORGANIZATION

2.1 SITE LOCATION/DESCRIPTION

The illegal dump site is part of an approximately 406-acre property located approximately

0.25 mile northwest of the San Diego County juvenile detention facilities and 0.40 mile north of the RJ Donovan Facility. The dump site is on undeveloped land that serves as a “buffer” around the RJ Donovan Facility. The site is accessed via a small service road off of Alta Road, with signage at the entryway identifying the site address as 405 Alta Road. The site is bordered by the now vacant Ingalls properties to the north; Otay Water District Pump Station 870-2 and Roll Reservoir, the San Diego Regional Firearms Training Center, several San Diego County juvenile detention facilities (including the Facility 8 Detention Facility, the George F. Bailey Detention Facility, and the East Mesa Juvenile Detention Facility), and Alta Road to the east; and the RJ Donovan Facility and undeveloped land to the south and west. The nearest private residential areas are located more than 2 miles north and south of the dump site. The nearest non-residential structures are part of the San Diego Regional Firearms Training Center, located approximately

0.2 mile to the east.

2.2 SITE OWNER

The site is currently owned by the CDCR. The designated contact for the site is Mr. Gregor Larabee, whose contact information is as follows:

Mr. Gregor Larabee Chief, Environmental & Regulatory Compliance Section California Department of Corrections and Rehabilitation 9838 Old Placerville Road, Suite B Sacramento, California 95827 Email: gregor.larabee@cdcr.ca.gov Office: (916) 255-2162

2.3 TOPOGRAPHY/GEOLOGY/HYDROGEOLOGY

The ground surface elevation at the site is approximately 530 feet above mean sea level and generally slopes to the northeast, although the elevation change from the site to an unnamed drainage is over 80 feet. The Otay River passes approximately 0.40 mile northwest of the site at its closest approach, with ephemeral streams in O’Neal Canyon and the unnamed drainage to the northeast. The site is in the western portion of the Peninsular Ranges geomorphic province of southern California. Published geologic maps for the area indicate the western portion of the province, in which the site is located, generally consists of Upper Cretaceous-, Tertiary-, and Quaternary-age sedimentary rocks. Bedrock beneath the site consists of the fanglomerate facies of the Oligocene/Miocene age Otay Formation, which is composed of poorly cemented boulder conglomerate and coarse-grained sandstone. The site is located in the Otay Valley Hydrologic Area, a subdivision within the larger Otay Hydrologic Unit. The Otay Hydrologic Unit

Bid Number C5613351-D Exhibit A-3 mailto:gregor.larabee@cdcr.ca.gov mailto:gregor.larabee@cdcr.ca.gov encompasses approximately 154 square miles and is drained by the Otay River and its tributaries.

Existing beneficial uses of groundwater in the Otay Valley hydrologic area include domestic and municipal supply, agricultural supply, and industrial service supply.

2.4 CURRENT AND FUTURE LAND USE

At the time of the drafting of this CHASP, the site is undeveloped land that serves as a “buffer” around the RJ Donovan Facility located south of the site. The site has been utilized for illegal dumping of waste materials, and an illegal easement has been constructed across the site to the neighboring Ingalls properties. The Ingalls properties are “land locked,” in that they are not accessible from a public road and there is no easement for the “upper access road” across CDCR’s property (Figure 1). Moreover, the Ingalls properties are not served by any utilities, including sanitary sewer, although water is provided via an unauthorized pipeline, which also passes through CDCR property.

Use of the site is currently governed by the CDCR and will continue to be used as a “buffer” area around the RJ Donovan Facility upon completion of site assessment and removal activities. The nearest residential development from the site is approximately 2.2 miles to the north, with several San Diego County detention facilities about 0.25 mile to the east and the RJ Donovan Facility about 0.40 mile to the south.

2.5 SITE HISTORY AND BACKGROUND

A review of historical photographs of the subject site show that, with the exception of a few jeep trails, the site and much of the surrounding area was vacant and unimproved until the mid-1960s.

By 1964, a service road and small pond had been constructed just east of the site. By 1966, the Otay Water District’s Roll Reservoir had been constructed to the north of the site, west of the small pond. The RJ Donovan Facility is visible in an aerial photograph taken in 1985, and by 1989, construction of George F. Bailey Detention Facility was underway east of the site. The 1989 aerial photograph also shows a jeep trail passing south of the site to the neighboring Ingalls properties, with the first structures present on that property. By 1994, some minor grading had occurred at the Ingalls properties and the jeep trail appeared wider and also may have been graded. Up until 1994, however, there does not appear to have been any disturbance of the ground surface in the investigation area.

In a Google Earth photograph taken in January 2000, several mobile homes are visible on the Ingalls property to the north, and the ground surface at the dump site had been disturbed. Given the topography in the disturbed area and the absence of any indication it was a borrow area, the disturbance is believed to reflect the first phase of illegal dumping in the investigation area. No further disturbance can be discerned in an aerial photograph taken in October 2001, indicating that the importation of fill appears to have ceased by this time, although there appears to be equipment at the dump site and the lower access road had been installed or improved since January 2000. At the time, the lower access road appears to have served one or possibly two mobile homes. Little to no change can be discerned in the investigation area in aerial photographs taken between November 2003 and April 2015, although fill appears to have been imported to the Ingalls

4.0 TASK HAZARDS AND REQUIRED CONTROL MEASURES

Based on the findings of the investigation conducted by Avocet and consistent with SDC’s October 18, 2018 email to CDCR, the area in which inert fill has been illegally deposited is not a “hazardous material site,” based on contaminant concentrations, where detectable, being negligible. Considering this and the very rural nature of the site location, there are no significant public health hazards and exposure pathways expected to result from forthcoming work. However, for contingency related purposes, potential public hazards and exposures resulting from dust, vapors, noise, and physical hazards are evaluated in this CHASP.

4.1 IDENTIFICATION OF POTENTIAL HAZARDS

Based on the investigation of the subject site, common compounds of potential concern at the dump site include benzo(a)pyrene and silica dust. Exposure to dust containing benzo(a)pyrene and silica dust is considered to be the primary exposure route of potential concern. Such substances can enter the unprotected body by inhalation, skin absorption, and/or eye contact. The Safety Data Sheets (SDS) for each compound of potential concern are included in Appendix A to this plan.

Although not considered a significant potential public hazard due to the remoteness of the property, excess dust and noise exposure are nevertheless considered potential nuisances to the public.

• Fugitive dust can arise during site activities. As such, dust control measures will be employed to reduce dust emissions during fill-disturbing activities. A source of water will be kept onsite during excavation activities at all times.

• Noise hazards can be created by equipment that generates noise in excess of auditory capacity thresholds. Noise in excess of human auditory thresholds can result in physical damage to the ear.

4.2 GENERAL CONTROL MEASURES

Control measures for the potential hazards are as follows:

• Site Security. To assist in excluding the public from the site, an exclusion zone (using signs, delineators, temporary fencing, caution tape and/or other acceptable methods) around areas subject to investigation or excavation activities will be established. It should be noted that access to the site is through a locked gate along Alta Road. As such, the gate will remain secured during field activities in order to further limit access to the site.

• Dust Control. Dust control methods will be taken to minimize potential public exposure to dust generated as a result of the planned excavation and fill removal activities. Dust suppression measures to be employed include reducing the pace of

Bid Number C5613351-D the excavations, as required, and/or maintaining levels of soil moisture by means of wetting or misting exposed soil surfaces. A source of water is available at the nearby RJ Donovan Facility, and water will be kept onsite using a water truck or trailer.

• Noise. Noise is considered to be a potential public nuisance for the project, but not a significant community health and safety concern. As such, noise monitoring is not proposed for the project. The contractor will, however, make best efforts to minimize noise during the course of the project. Work hours for the project will vary but are not anticipated to occur outside of the days Monday through Friday, between 7:00AM and 5:00PM.

• Open Trenches. If open trenches are needed, they will be backfilled by the end of each workday. During trenching activities, no personnel shall enter into trenches deeper than 4 feet.

• Stockpiled Soil. Excavated soil will be temporarily stockpiled and misted with water, as needed, or covered with plastic sheeting to reduce the potential for dust and runoff. Excavated soil will not be allowed to sit out overnight, with all soil placed back in the excavations by the end of each day.

4.3 STORMWATER MONITORING AND DRAINAGE

To prevent materials disturbed during planned site activities from entering the nearby ephemeral stream, WCG will be prepared to implement and maintain the following stormwater BMPs:

• Stop intrusive field activities during rain events;

• Cover excavated stockpiles with plastic sheeting if unable to backfill trenches before the start of rain; and

• Place straw waddles around excavation area(s) where runoff could occur.

4.4 AIR MONITORING

Air monitoring at the site will focus on dust generation while field procedures will focus on preventing the same. As the illegally dumped fill has been exposed to the elements for a significant amount of time, VOCs are considered unlikely to be present. However, potential VOCs will be monitored with a hand-held photoionization detector (PID) during excavation and handling of disturbed material. The frequency of the readings will be determined by the nature of the site activities conducted on a given day/shift and may be modified at the discretion of the SSO. Air monitoring results will be recorded on monitoring logs, an example of which is included in Appendix B. If the PID detects VOCs, all work is to stop until further assessment is conducted regarding the source(s) and levels of VOCs. As needed, necessary modification to site control

California Department of Corrections and Rehabilitation (CDCR) Community Health and Safety Plan

Bid Number C5613351-D measures will be implemented. Work would only resume after assessment and approval from the PM and the HSD.

WCG does not propose conducting dust monitoring utilizing field instruments during the course of the project. There is a zero dust policy in place for the project, and soil will be continuously moistened to minimize dust generated during the earthwork activities. If visible dust is observed in the immediate work area, the soil disturbance activity will be halted until better or more frequent dust control measures can be implemented. If control measures appear inadequate, work will stop and only resume with the approval of the PM and HSD. Preventative measures to be implemented during field activities will include wetting or misting exposed soil surfaces, as necessary, with potable water prior to soil disturbance; wetting or misting disturbed soil, as necessary, during excavation; and handling disturbed soil in such a way as to minimize the potential generation of dust. For example, during the planned trenching program, the backhoe operator will be instructed to minimize the potential for dust generation by carefully depositing spoil from the trenches, as opposed to dropping it from several feet.

If field evidence of asbestos containing materials, such as insulation, fire retardant, asbestos cement (transite), vinyl floor tiles, etc., is documented in the fill materials, all work is to stop until further assessment is conducted to confirm/refute the presence of asbestos. As needed, necessary modification to site control measures will be implemented. Work would only resume after assessment and approval from the PM and the HSD.

5.0 WORKER HEALTH AND SAFETY

This CHASP is not a worker health and safety plan. Worker health and safety measures are outlined in the site-specific HASP (WCG, September 18, 2024). In general, the HASP describes chemical and physical hazards that may be encountered during site work and the “generic” hazards associated with working with and around heavy equipment, such as excavating equipment. The HASP specifies the procedures and measures to be followed to eliminate or minimize these hazards. WCG’s field personnel are required to follow the HASP. Subcontractors under WCG’s control are required to follow the HASP or their own health and safety procedures as long as they are at least as stringent.

6.0 SITE TRAFFIC CONTROL

As already mentioned, the ingress and egress point for the site is from the access road entryway off Alta Road (Figure 2). During investigation activities, the gate will remain secured to minimize unscheduled visitors to the site. During eventual fill removal activities, prior to the transport of fill offsite, each truckload will be inspected to ensure that the loads are adequately covered and properly manifested. The contractor will also be responsible for ensuring that trucks are cleaned of misplaced soil that may be present on the vehicles. As trucks leave the site, they will be assisted by a flag person, as needed, to ensure safe merging into oncoming traffic.

7.0 EMERGENCY PLANNING

If a community emergency arises, the SSO will immediately coordinate the appropriate emergency response with other onsite personnel, LEA, and the County of San Diego Fire Authority. In the event of an emergency, work at the site will be stopped. The exclusion zone will be maintained, with only authorized site workers and emergency service personnel being allowed into the zone.

In the event of a fire, any potentially flammable materials will be moved from the path of the fire to an area judged to be safe and 911 will be called.

Potential site emergencies include, but are not limited to fire, earthquake, heat stroke, and other physical or chemical injuries that require immediate medical attention. The SSO will respond to onsite emergencies, direct site evacuation, summon emergency assistance, as necessary, and contact the PM and HSD. The SSO will turn over the responsibility for coordination of an emergency to appropriate emergency personnel upon their arrival.

7.1 PRE-EMERGENCY PLANNING

Emergency contacts, telephone numbers, and the hospital route will be readily available at the site.

A place of refuge and/or emergency meeting place will be designated by the SSO at the daily safety meeting. Following an evacuation pursuant to a site emergency, field personnel will meet at the designated meeting place for a head count. Plans for a safe and effective response to potential emergencies will be developed by the SSO before daily field activities begin. Pre-emergency planning includes reviewing the emergency response plan with site personnel and inspection of emergency response equipment and supplies.

7.2 PERSONNEL ROLES, LINES OF AUTHORITY, AND COMMUNICATION

In the event of an emergency, the SSO must be notified. The SSO is responsible for responding to the immediate emergency. The initial response may include, but is not limited to, notifying onsite personnel, evacuating the area, and notifying the appropriate emergency response authorities, as needed. The SSO shall inform the HSD and PM that an emergency has occurred.

However, all field personnel present at the site have the authority and responsibility to report a site emergency.

7.3 EMERGENCY RECOGNITION AND PREVENTION

The likelihood of emergencies occurring will be minimized through proper supervision, employee training, and site management. The impact of the emergency will be minimized to the extent possible.

7.4 EMERGENCY SITE SECURITY AND CONTROL

The locations of site resources and emergency equipment will be discussed at the site safety orientation meeting prior to commencement of site work. In the event of an emergency, the SSO

Bid Number C5613351-D or designated alternate will control access and traffic to the work zones. The SSO is responsible for maintaining emergency site security.

7.5 FIRE

All field personnel are authorized to use a fire extinguisher if a fire is small and does not endanger their health or life or the health and life of others, is caused only by project operations, and is within their ability to control. Smoking is not permitted in designated work areas. Open flames and spark-producing equipment are prohibited in areas where flammable liquids or gases are used or may be generated. Open flames and spark-producing equipment are prohibited in areas where flammable liquids or gases are used or may be generated. Open flames are prohibited within 75 feet of points where flammable liquids or gases may accumulate. Although not anticipated for the project, if flammable combustible liquids in quantities greater than 1 gallon are stored at the project site during the construction activities, only Factory Mutual/Underwriters Laboratories-approved containers will be used for handling and storing such materials. An electrical bond must be maintained between containers when flammable liquids are being transferred, and equipment must be grounded. Any rags or other waste material soaked with combustible or flammable liquid must be disposed of in a closed container. Heavy equipment and vehicles will each be equipped with a fire extinguisher.

In the event of a fire or explosion, the area will immediately be evacuated and the fire department summoned as soon as possible. Air or vehicle horns will be used to alert all site personnel of the fire and evacuation. Site personnel will gather at a designated location upwind of the predominant wind direction. The location will be established during the daily safety meeting in the morning and a head count will be taken.
