CA 93313 805/831-1646 ° FAX 8051831-1771 Soil Excavation Work Plan Advanced Environmental Concepts, Inc. 3.0 WORK PLAN 3.1 Site Description The Orin Way property is located on the north side of Orin Road east of Pierce Road. The general area is comprised of oilfield and industrial related service industries. The facility is at an average elevation of 400-feet above mean sea level with minimal topographic relief. 3.2 Regional Geology The subject property is located in the Southern San Joaquin Valley (Valley) which is a part of the Central Valley of California. The Valley forms the southern two-thirds of the Central Valley and is characterized as a broad structural trough. It is bordered on the east by the Sierra Nevada Range and on the west by the Coast Range [Diablo and Temblor Mountains). The Valley extends 250-miles southeastward from the confluence of the San Jaaquin and Sacramento Rivers to the Tehachapi and San Emigdio Mountains. The width ranges from 25-miles wide near the Kern River to approximately 55-miles wide near the Kings River, with an approximate average width of 40-miles. Geology of the southern Valley consists of a Pre-Tertiary basement complex overlain by marine and non-marine sedimentary rocks of Tertiary age. These rocks are composed of consolidated sandstones, siltstones and shales which thicken from northeast to southwest. The Valley was once an inland sea of comparatively shallow depth that continued to subside due to the ever increasing load of sediments transported and deposited from higher elevations. These deposits consist of gravels, sands, silts and clays. The majority of the groundwater pumped from the Valley floor occurs within these relatively unconsolidated continental deposits. 3.3 Local Geology The investigated property is located on alluvial deposits, created from sediments transported and deposited by local streams, and during flood stages of the Kern River. The site is situated in a Iow to moderate energy flood plain environment consisting of weakly consolidated to unconsolidated, poorly bedded sands and silts. 3.4 Hydroge°logy Ground and surface water in the north Bakersfield area is regulated by the Kern County Water Agency Improvement District. According to the Kern County Water Agency "Water Supply Report-1990", depth to groundwater in unconfined and equivalent wells is estimated at 50-feet below grade level (BGL] at the site. No perched water-bearing zones are identified. Groundwater quality is unknown at this time. Project: AEC 94V-t415 5 · ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND 4400 ASHE ROAD. #206 * E~AKERSFIELD. CA93313 8051831-1646 '* FAX 8051831-1771 Soil Excavation Work Plan Advanced Environmental Concepts, Inc. 3.5 Potential Affected Soil Analytical data of soil samples indicates the presence of hydrocarbons in soil to a depth of approximately 20 feet BGL and extends laterally from the clarifier[s), about 15 feet. Approximately 10[] cubic yards of soil in a quasi-cylindrical shape adjacent the southern clarifier, and approximately 15 yards of soil from the dry well located adjacent the western side of the building appear to be affected. 3.6 Excavation Methods An excavator will be used to remove the soil to a depth of approximately 22 feet BGL in the area affected by the clarifiers/dry wells. Actual excavation dimensions will be determined in the field based on soil screening criteria and consultation with the KCEHD inspector. All soil removed from the clarifiers/drywell[s] area will be monitored for hydrocarbons and volatile organic compounds [VOC's] during the excavation operations to ensure proper segregation of the impacted soil from the clean soil. Air monitoring will be conducted at the excavation using a Photoionization Detector [PID}, calibrated to 50 parts per million hexane. Soil will be tested with the PID by placing a representative amount of material into a capped brass sleeve and analyzing the headspace after a five minute period. 3.7 Sampling Methods Upon excavation of the sail, sampling will be conducted in accordance with all County guidelines. The excavator will collect representative samples of native soil at 10-foot intervals from the four sides of the pit near the floor level. Another sample will be collected from the excavation floor as per KCEHD guidelines. The excavator will bring each soil sample to the surface for collection and subsequent laboratory analyses. Approximately two composite soil samples will be collected from the stockpile no more than three days following the excavation to characterize the soil for disposal. The following sample collection procedure will be used: A qualified AEC representative will tap a I 1/2-inch diameter by 6-inch long brass sleeve into an undisturbed portion of the stockpiled soil; The brass sleeve will be sealed with Teflon liners, plastic end caps, and tape after ensuring that no head space is present; The brass sleeve will then be labelled, placed in a sealable plastic bag, and stored in a cooler chilled with Blue Ice; All soil samples will be recorded on a chain-of-custody document to ensure sample integrity and traceability; Project: AEC 94V-1415 6 · ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND · 4400 ASHE ROAD. #206 '* BAKERSFIELD.

Health & Safety Plan for Orin Way Property 3404 Orin Road County of Kern · Bakersfield, California Introduction: A Site Safety Plan [SSP] has been designed to address safety provisions needed during the site soil assessment/remediation. It's purpose is to provide established procedures to protect all on-site personnel from direct skin contact, inhalation, or ingestion of potentially hazardous materials that may be encountered at the site. The SSP establishes personnel responsibilities, personal protective equipment standards, decontamination procedures and emergency action plans. Advanced Environmental Concepts, Inc. seeks to enter the property described above for the purpose of conducting a site assessment, consisting of backhoe excavation and sampling, to remove hydrocarbon impacted soil. Soil samples will be collected following the complete excavation of affected soil. All possible efforts will be made to collect undisturbed samples. Each sample to be chemically analyzed will be collected in a brass sleeve, capped with lined plastic lids, sealed with tape and placed on ice in a cooler immediately. All Chain-of-Custody protocol will be followed. Excavation equipment will be brought to the site and operated by: Kern Backhoe Services 3752 Allen Road Bakersfield, California 93342 [805] 589-5220 This SSP describes means for protecting all on-site personnel from deleterious contamination of personal injury while conducting on-site activities. As described below, we will strive to meet all requirements promulgated by the California Department of Health Services. Responsibilities of Key Personnel: All personnel on-site will have assigned responsibilities. Mr. Jonathan L. Buck will serve as project manager and on-site engineer. He will also serve as Site Safety Officer [SSO]. As SSO, Mr. Buck will assure that on-site personnel have received a copy of the SSP. Personnel will be required to document their full understanding of the SSP before admission to the site. Compliance with the SSP will be monitored at all times by the SSO. Appropriate personal protective equipment, listed below, will be available and utilized by all on-site personnel. Prior to beginning work, the SSO will conduct a training session to assure that all are aware of safe work practices. In the training session, personnel will be made aware of hazards at the site and will utilize Material Safety Data Sheets for information on compounds to be encountered. Mr. Buck will also be responsible for keeping field notes, collecting and securing samples, and assuring sample integrity by adherence to Chain-df-Custody protocol. Project: AEC 94V-1415 I Health & Safety Plan Advanced Environmental Concepts, Inc. All on-site employees will take reasonable precautions to avoid unforeseen hazards. After documenting their understanding of the SSP, each on-site employee will be responsible for strict adherence to all points contained herein. Any deviation observed will be reported to the SSO and corrected. On-site employees are held responsible to perform only those tasks for which they believe they are qualified. Provisions of this SSP are mandatory and personnel associated with on-site activities will adhere strictly hereto. Job Hazard Analyses: Hazards likely to be encountered on-site include those commonly encountered when operating any mechanical equipment, such as the danger of falling objects or moving machinery. Simple precautions will reduce or eliminate risks associated with operating such equipment. An excavation contractor will be retained to deliver and operate all excavating equipment. Qualified personnel only. will have any contact with this equipment. All on-site personnel, including the excavation contractor and his employees, are required to wear hard hats when in close proximity to excavating equipment. Latex sampling gloves will be worn by persons collecting or handling samples to prevent exposure to contaminants. Gloves will be changed between samples and used ones discarded, to avoid cross-contamination. A suitable vapor suppression method, such as water application via fire hose, will be implemented in the event average downwind VOC levels measured by the photoionization detector [PID] are at least I0 ppm over the ambient background level. Proper respiratory equipment will be worn by all on site personnel if PID readings continue.to exhibit VOC levels of at least 10 ppm over the background level. Furthermore, no on-site smoking, open flame or sparks will be permitted in order to prevent accidental ignition. Risk Assessment Summary: Exposure to chemicals anticipated on-site include gasoline, diesel, and benzene, toluene, and xylene [BTX]. These chemicals represent a hazard because they are moderately to extremely toxic and most are highly flammable. Threshold Limit Values [TLV's], Shod Term Exposure Limits [STEL's] and Toxicity levels [LD50, oral-rat], all in mg/kg (ppm), are listed below: Compound TL¥ STEL Toxicity Gasoline 200 300 .... Diesel 50 75 .... Benzene 10 25 4894 Toluene 100 150 5000 Xylene I O0 150 4300 Project: AEC 94V-~1415 2 Health & Safety Plan Advanced Environmental Concepts, Inc. Exposure Monitorin~ Plan: Air monitoring will be conducted during excavation prOcedures using a TIP-r~II Photoianization Detector [PID] equipped with a ~0.6eV lamp, manufactured by Photovac, Inc. The PID will be calibrated to 50 ppm hexane. These air monitoring procedures will be carried aut In accordance with the provisions presented in Rule 463.5, San Joaquin Valley Unified Air Pollution Control District [APCD]. Excessive volatile emissions are not anticipated but will be continually monitored. Personal Protective Equipment: When handling samples, the on-site Geologist will wear latex gloves. Hard hats will be worn by all personnel on-site when in proximity of excavation equipment. Work Zones and Security Measures: Access ta the site will be restricted to authorized personnel. A set of cones, placards or wide yellow tape, surrounding the site, will define the perimeter, if needed. The Project Manager will be responsible for site security. Decontamination Measures: Avoidance of contamination whenever possible is the best method for protection. Common sense dictates that on-site personnel avoid sitting, leaning or placing equipment on possible contaminated soil. All personnel will be advised to wash their hands, neck and face with soap and water before taking a break or leaving the site. Excavation and sampling equipment used will be decontaminated by steam-cleaning. Sampling equipment will be decantaminated before each sample collection. General Safe Work Practices: On-site personnel will be briefed each day in "tailgate" meetings as to the day's goals and equipment to be used. Anticipated contaminants and emergency procedures will be reviewed. Appropriate personal protective equipment will be put on and verified correct by SSO, including respirator fit. Excavation and sampling equipment will be steam-cleaned before being brought on-site. The on-site Geologist will oversee operations and log the excavation strata. The Sample Coordinator will assure that proper protocol is used at all times in collecting and handling samples. Training! Requirements: The SSO will conduct a pre-site training session which will include all points of MSDS forms, contaminant properties, warning signs, health hazard data, risk from exposure and emergency first aid. Project: AEC 94V-t415 3 Health & Safety Plan Advanced Environmental Concepts, Inc. All chemicals are to be covered and the SSO will assure that everyone fully understands site hazards. Medical Surveillance Proaram: According to CFR 29, 1910.120, Paragraph [fi, employees who wear respirators thirty [30] days or more during one [I] year or who have been exposed to hazardous substances or health hazards above established permissible exposure limits are required to be monitored medically. All site personnel will be required to have had a complete chemical physical within the past year. Record Keepin~l: Documentation will be kept on personnel exposed to contaminant hazards on the job site according to OSHA regulations. These will include documentation that employees have received training on the SSP, respiratory protection, MSDS forms and all emergency procedures. These will be reviewed during the pre-site training meeting. Exposure records on each job will be kept for thirty (30] years to meet requirements. Included will be names and social security numbers of employees, medical evaluations, on-the-job logs from entry to exit, first aid administered, visits on-site by outside persons and personal air monitoring records. Continaency Plans: In the event of an accident, injury, or other emergency, the Project Director, Senior Project Manager, or other person, will notify the appropriate government agencies or individuals as follows: Kern County Environmental Health Department 2700 M Street, Suite 300 Bakersfield, CA 93301 [805] 86t-3636 Police, Fire or Ambulance Emergency 9-t-t Nearest Emergency Hospital Mercy Hospital 2115 Truxtun Avenue Bakersfield, CA 93301 (805) 327-337 t Project: AEC 94V-14t5 4 'Appendix C' LABORAORY REPORTS / CHAIN-OF-CUSTODY DOCUMENTATION Purgeable Aromatics and Total Petroleum Hydrocarbons JIM'S SUPPLY Date of 3530 PIFRCE ROAD Report: 02/25/94 BAKERSFIELD, CA 93308 Lab #: 94-01690-1 Attn.: KEVIN BLYLAN 324-6514 Sample Description: DRAKE-UPS: CLARIFIER-S WATER FROM SOUTH CLARIFIER COMBINATION AT FORMER UPS FACILITY, 02-15-94 BE~"~EEN 1430 1500 HRS SAMPLED BY JON BUCK TEST METHOD: TPH by D.O.H.S. / L.U.F.T..Manual Method - Modified EPA 8015 Individual constituents by EPA Method 5030/8020.
