The 10" and 6" lines were scheduled to be connected together to reroute the water around the landfill. The area scheduled to be excavated was within one hundred feet of the Palomar Airport Landfill Unit II. Methane gas was expected to infiltrate the work area because of recent high surface monitoring readings in the surrounding area. The location of work is shown in Appendix, Section III. MONITORING EQUIPMENT Methane is flammable at 120,000-150,000 ppm or 12%-15% concentration. An OVA and an LEL/02 meter were used to monitor the level and concentration of methane present. The OVA is used to read parts per million (ppm) . The LEL/O2 meter converts ppm into a 100 percentage digital scale with an alarm set to go off at 25% or greater methane concentration, less than 19.5% oxygen or greater than 25% oxygen. The LEL/02 meter is placed in the excavated area and the OVA is placed outside the work area for double monitoring. MONITORING EQUIPMENT CALIBRATION In order for the monitoring to reflect the most accurate readings the OVA was office laboratory calibrated to standard methane calibration gases each day before work started. The LEL/O2 meter is an electronical device that is factory calibrated and does not require recalibration on a daily basis. The OVA calibration sheets are provided in Appendix, Section II. DESCRIPTION OF WORK PERFORMED EXCAVATION The approximate location of the pipe was painted on the pavement prior to the contractors commencement of work. Surface monitoring for methane gas was performed in the designated area and found to have no indications of methane present. A sweep was made of the surrounding area and approximately one hundred feet away surface readings of 20,000 ppm were found. The Wilson Corporation excavated the designated area approximately twelve feet wide by twelve feet long. The soils encountered were mixed fill materials. Excavation was performed with extreme caution to avoid sparks caused by the bucket. As the excavation continued to a depth of 9 ft the ppm level rose, methane concentration increased slightly and the oxygen level dropped to below 19.5% at one point. In addition there was a shoring problem and a lack of work space with step wall excavation. It was determined that the area of excavation was to be increased to twice the width or twelve feet by twenty-four feet long and fifteen feet deep. Monitoring continued with readings decreasing due to an increase in natural ventilation. At a depth of twelve feet a light colored clay was encounter. This clay continued to a depth of fifteen feet or bottom of excavation. I examined the bottom of excavation and found very low readings in the middle but the east wall was reading (lOOppm) or .08% LEL methane concentration with a higher reading of 6,000 ppm at the pipe penetrations and a 1% LEL methane concentration. This indicated a presents of other gases. The higher reading would dissipate rapidly to less than 100 ppm at a distance of four inches. I notified the contractor of the possible trouble spots. In general, all during the excavation process the methane concentration and oxygen level was well within the safety limits. Except for the east wall, most high readings dissipated with a life span of a one second or less. The site was visited periodically by the Airport Authorities, Carlsbad City Inspectors, Carlsbad Fire Department, and the staff from the county Solid Waste Division. After excavation was completed both of the water lines were cut and capping or connections made. The cutting and rerouting operation was continuously monitored while the Fire Department and the Paramedics were in the area. The readings during this operation were well within safety limits due to a ventilation fan operating at the time. The backfill operation indicated a concentration of 100 ppm on the OVA and or less then, 1% LEL of methane, with near normal oxygen. DAILY LOGS The detailed daily reports are provided in Appendix, Section II with monitoring results. The location of the work is found in Appendix, Section III. SUMMARY In summary, methane concentration readings fell far below the minimum safety standards everywhere except for the east wall that faces Unit #2 Landfill. The readings from the east wall indicated surges of gases coming from either gas pockets where gas has been collected or directly from the landfill itself. The readings dissipated rapidly with distance from the wall indicating low gas pressure. However, if the gas pressure would have increased at any time the level of methane concentrations in the excavated area could have changed to an unsafe condition very rapidly.

Subject: Palomar Landfill -- Proposal for Monitoring Construction Dear Mr. Azuela: D Thank you for your recent invitation to submit a proposal on work planned by the Carlsbad Water District at the Palomar Landfill facility. We understand the Carlsbad Water District plans to excavate for the purpose of exposing an existing water main that is located within H the landfill limits. The pipeline is reportedly under 12 to 20 feet of fill. Further, it is anticipated that the excavation will expose people in the immediate construction area to landfill generated methane gas. The purpose of the presence of the M&E staff is to monitor the gas concentration and keep the responsible parties informed of the methane presence. Based on this information, we have enclosed our proposal for carrying out the monitoring task for the County. Also, enclosed for your easy reference is David Stone's resume, with your permission, we would propose to assign him to this project. Mr. Stone is certified in the State's hazardous waste program. I would suggest that the Carlsbad Water District be provided with a copy of the Palomar Landfill Health and Safety Plan, dated May 22, 1992 that was assembled for your office by M&E. They should carefully read this before scheduling any work within the landfill units. Please call me if you need additional information or to discuss this proposal in more detail.

Job #: 006716 Location: Southeast portion of the City of Carlsbad at the north- west corner of Palomar Airport Road and El Camino Real. Reviewed by: Bill Collier, CIH Date: January 17, 1992 1.1 INTRODUCTION This Site Health and Safety Plan (HASP) document defines general applicability and general responsibilities with respect to compliance with the Health and Safety program for the installation and sampling of offsite gas monitoring wells, soil borings, groundwater monitoring wells, and the monitoring o*f worker safety during surface construction enterprises. The HASP also addresses the health and safety concerns associated with performing these activities at an operational airport. 1.2 SCOPE AND APPLICABILITY OF THE SITE HEALTH AND SAFETY PLAN The purpose of this Site Health and Safety Plan is to define the requirements and designate protocols to be followed at the Site during remedial investigations. Applicability extends to all Government employees, contractors, subcontractors, and visitors. All personnel on site, contractors and subcontractors included, shall be informed of the site emergency response procedures and any potential fire, explosion, health, or safety hazards due to the H&S/PALOMAR.01 1-1 monitoring activities and related airport operations. This HASP summarizes those hazards and defines protective measures planned for the site. An exclusion zone for this facility will be defined as a 20-foot radius around the proposed locations of the monitoring activities. A limited exclusion zone area has been chosen to prevent interrup- tion of the ongoing operations at the airport. This plan must be reviewed and an agreement to comply with the requirements must be signed by all personnel prior to entering the exclusion zone or decontamination zone. During development of this plan, consideration was given to current safety standards as defined by FAA/EPA/OSHA/NIOSH, which include safety concerns for operations at an airport, health effects and standards for known contaminants and procedures designed to account for the potential for exposure to unknown substances. Specifically, the following reference sources have been consulted: • OSHA 29 CFR 1910.120 and EPA 40 CFR 311 • FAA Advisory Circular, Operational Safety on Airports during Construction • U.S. EPA, OERR ERT Standard Operating Safety Guides • OSHA/NIOSH/EPA/USCG Occupational Health and Safety Guidelines NIOSH Pocket Guide to Chemical Hazards • (ACGIH) Threshold Limit Values Visitors All visitors entering the decontamination zone and exclusion zone at the Site will be required to read and verify compliance with the provisions of this HASP. In addition, visitors will be expected to comply with relevant OSHA requirements such as medical monitoring, H&S/PALOMAH.01 1-2 training, and respiratory protection (if applicable). Visitors will also be expected to provide their own protective equipment. in the event that a visitor does not adhere to the provisions of the HASP, he/she will be requested to leave the work area. All nonconformance incidents will be recorded in the site log. u IQ H8.S/PALOMAR.01 SECTION 2 SAFETY AND HEALTH RISK ANALYSIS 2.1 HISTORICAL INFORMATION The Palomar Airport Landfill site was in operation as a sanitary landfill from 1962 to 1975. The airport property has a total area of 241 acres. The waste fill area is approximately 70 acres. Approximately 80% of the waste was residential and 20% agricul- tural. Since its completion in 1975, fill Units 1 and 2 have been paved over and are being used in the airport operations. Portable hangars have been erected over Unit 1. Settlement is apparent over much of Unit 1 and some of Unit 2. As a result of this settling, many of the hangars in Unit 1 are showing distress. Severe settlement has also occurred in the paved east/west access road south of Unit 1 causing cracks in the landfill cover. A preliminary review of the 1988 data collected during the Air Quality Solid Waste Assessment Tests (SWATs) demonstrated that Integrated Surface Monitoring results did not exceed 2 ppb. However, readings as high as 20 ppm were detected over the unpaved area of Unit 1, along the toe of the southern border. Elevated readings above background were measured infrequently in cracks in the pavement. Methane surface monitoring activities were conducted at the Palomar Airport in March and April, 1991. During these activities, methane emissions in excess of 500 ppm were detected from cracks in the asphalt cover of Unit l and Unit 2. Monitoring data has indicated that there is not a significant likelihood of exposure to methane in the breathing zone. The County of San Diego is currently H&S/PALOMAR.02 2-1 D implementing mitigation measures to seal the cracks to reduce and eliminate these emissions. P, Considerations For Remedial Operations LJ It is important for all personnel to review the monitoring considerations on page 2 of this section. 2.2 SITE HAZARD OVERVIEW Site hazards for this facility may defined into two categories; n hazardous associated with the monitoring activities (monitoring ^ hazards) and hazards associated with performing monitoring r-j activities at an operational airport (construction hazards) . The U monitoring hazards are primarily due to chemical exposure while construction hazards are primarily due to physical hazards. jj Now that the project is at a more advanced stage there is a need to closely monitor situations in which there will be an opening of the surface material that might uncover subsurface gas pockets. Normal Site Hazards and Considerations for Monitoring Activities H The following checklist identifies the potential hazards at the Site as a result of the monitoring activities. The purpose of this D list is to provide onsite personnel with a general understanding of the hazards which might be encountered within the exclusion zone. SPECIAL MONITORING CONSIDERATIONS • In areas where asphalt is to be removed during the remediation portion of this plan precautions should be taken to insure that monitoring of the area is conducted R with an organic vapor analyzer. If the meter indicates an exposure level to airborne gases at or above 50 ppm, Q then respiratory protection is to be required of all personnel. If the meter indicates an exposure level pi above 100 ppm, then airline supplied units are to be U used. If the level of airborne exposure is at or above 750 ppm, then the area should be evacuated. ,_, H&S/PALOMAR.02 2-2 Apparent Hazards: Type of Facility:,Status of Facility: Serious Moderate Low X_ None Unknown Imp.

Generally, the dust and the gases will not be either the type that are considered toxic, nor ones that would be expected to be at a concentration that would represent a serious health hazard or a fire/explosion hazard. Hazards generally associated with these monitoring activities include: • Contact with or inhalation of contaminants, potentially in high concentrations in sampling media. • Contact with or inhalation of contaminants, potentially in high concentrations during facility maintenance • Back strain and muscle fatigue due to lifting and installing wells or probes. • Contact with or inhalation of decontamination solutions. Table 2-1 provides a summary of hazards due to potential contami- nants exposure during monitoring activities based on experience H&S/PALOMAR.02 2-3 from other landfill sites. The possible contaminant monitoring methods may be implemented in the event that the safety officer determines there is a significant threat to worker safety from site exposure. The safety officer is responsible for monitoring activities to insure that the level of exposure to airborne contaminants due to exceed the Permissible Exposure Limits or the guidelines set forth on page 9 of this section.

Keep the affected person warm and at rest. Get medical attention as soon as possible. If this chemical has been swallowed, get medical attention immediately. (NIOSH, 1987. Hazard Prevention Precautions • To minimize exposure to chemical contaminants, an ongoing review of suspected contaminants will be conducted and as conditions change personal protection needs will be adjusted. • Level D protection is proposed at this site based on current possible exposure information. Refer to Section 3 for a discussion on Level D requirements. H&S/PALOMAR.02 2-6 • Proper lifting (pre-lift weight assessment, use of legs, multiple personnel) techniques will prevent back strain. Use slow easy motions when installing wells or probes to decrease muscle strain. • Industrial hygiene or air monitoring may be implemented if deemed necessary by the Safety Officer. • Material Safety Data Sheets for all decon solutions will be included with each Site Health and Safety Plan. • First aid equipment will be available based on MSDS requirements. considerations for Airport Work Site In addition, there are potential construction hazards associated with performing monitoring activities at an operational airport. However, note that exclusion zones(zones of actual work in contaminated areas) should not interfere with the aircraft opera- tional areas and monitoring stations will not be located on a runway, landing strip, associated taxiway, or impact navigable air space. Based on information identified by the FAA, (Advisory circular, operational safety on airports during construction, 5/31/84, AC No. 150/5370-2C (Please see Appendix I) indicating potential hazardous conditions or improper construction activities, Metcalf & Eddy, Inc. and their subcontractors will take appropriate precautions to prevent the following hazards or conditions: • Excavation adjacent to runways, taxiways, and aprons. • Mounds or stockpiles of earth, construction material, temporary structures, and other obstacles in proximity to airport operations areas and approach zones. • Heavy equipment, stationary or mobile, operating or idle near airport operations areas or in safety areas. • Proximity of equipment or material which may degrade radiated signals or impair monitoring of navigational aids. H&S/PALOMAR.02 2-7 • Tall but relatively low visibility units such as cranes, drills, and the like in critical areas such as safety areas and approach zones. • Improper or malfunctioning lights or unlighted airport hazards. • Holes, obstacles, loose pavement, trash, and other debris on or near airport operations areas. • Open trenches along side pavement. • Attractions for birds such as trash, grass seeding, or ponded water on or near airports. • Inadequate or improper methods of marking temporarily closed airport operations areas including improper and unsecured barricades. • Obliterated markings on active operational areas. In addition to the above, Metcalf & Eddy, Inc. and their subcontractors will take the following precautionary measures: • Identify pull back areas and clearance heights. • Notify airport personal through the proper chain of command when construction activities are to occur. • Install and maintain temporary lighting and marking for closed or diverted aircraft routes or aircraft operations areas, if necessary to construction activities. • Minimize disruption of standard operating procedures for aeronautical activities. • Insure that first aid equipment is be available. • Insure that appropriate marking/lighting of construction equipment is performed. • Storage of construction equipment and materials when not in use. • Wear_ear plugs when jets are nearby. • Keep routes from fire fighting and rescue stations to active airport operations areas and safety areas clear. • Notify appropriate authorities prior to changing safety- oriented aspects of the site plan. H&S/PALOMAR.02 2-8 Inform airport authorities when there is a need to suspend or restrict aircraft activity as a result of monitoring operations or about activity, within the knowledge of Metcalf & Eddy, Inc., over which we have no control, that might effect aircraft activity.

During remedial activities at this site, field personnel will be equipped with Level D protection due to the '"I low potential for hazard. Level D is a level of protection ^ identified in 29 CFR 1910.120. The classification scheme of >—i personal protective equipment specified by that standards is as J follows: n H4S/PALOMAR.03 3~3 Level A: Should be worn when the highest level of respira- tory, skin, and eye protection is needed. Level B: Should be worn when the highest level of respira- tory protection is needed, but a lesser level of skin protection. Level B is the primary level of choice when encountering unknown environments. Level C: Should be worn when the criteria for using air- purifying respirators are met, and a lesser level of skin protection is needed. Level D: Should be worn in any area where respiratory or skin hazards are essentially non-existent. It provides minimal protection against chemical hazards.

The master copy (with signature sheet) of this Safety Plan will be held by the designated on-site Safety Officer. • There will be no smoking, eating, chewing gum, drinking or application of cosmetics in the Exclusion or Decontam- ination zone. • All contractor or subcontractor personnel shall bring to the attention of the site Health & Safety Officer any unsafe condition or practice associated with site activities. • Hands, face and all other potentially contaminated areas shall be thoroughly cleaned prior to smoking, eating or leaving the site. • Inspectors must avoid unnecessary contamination (i.e., walking through known or suspected "hot" zones or contam- inated puddles, kneeling or sitting on the ground, leaning against potentially contaminated barrels or equipment). • Respiratory devices may not be worn with beards, long sideburns, or under other conditions that prevent a proper seal. • All project personnel who are likely to wear air purifying or air supplied respirators must first meet the training and medical requirements of 29 CFR 1910.120 and 29 CFR 1910.134. • All accidents and/or injuries shall be immediately report- ed to the site Health & Safety Officer. If necessary, a first report of injury will be initiated by the site safety officer and provided to the Regional Safety Officer for processing. See Appendix A. • No contact lenses may be worn within the site Exclusion or Decontamination zones. H&S/PALOHAR.04 4 -2 Daily safety meetings will be held at the start of each site operation to discuss current site conditions, airport operations and aircraft traffic, field tasks being per- formed, plan modifications and work concerns. No matches or lighters may be brought into the Exclusion or Decontamination zones. All drilling and excavation equipment with the potential to impact navigable air space must have markings or lighting which is easily identified from the air. All onsite personnel will be informed of any pullback distances or required clearances. All drilling and excavation activities requiring the use of heavy construction equipment must be performed while in compliance with the applicable safety regulations in OSHA 29 CFR 1926. Excavation activities must be performed while in compli- ance with OSHA 29 CFR 1926 subpart P. Aerial obstructions such as power lines and tree branches will be verified prior to erection of drill rig masts or movement of large equipment. A 20-foot horizontal clear- ance must be maintained between all aerial obstructions. Locations of subsurface utilities and buried wastes shall be verified prior to any drilling or excavation activi- ties. No project personnel may be allowed onsite without the prior knowledge and consent of the designated site Health and Safety Officer and project manager. Guidelines specified in Appendix H, Special Safety Re- cmirements During Construction must be followed during monitoring activities. H&S/PALOMAR.04 4-3 ADDITIONAL REQUIREMENTS There is a requirement for continuous monitoring of the potential for airborne releases of methane gases or other chemical substances. When a section of the site's surface is disturbed in a manner that could result in the release of trap gas pockets. This monitoring must be done with an organic vapor analyzer. At the follwowing level of air- borne contamination these actions are required: 50 ppm air purifying respira- tors 100 ppm Airline supplied respi- rators 750 ppm evacuate the area D H&S/PALOMAR.04 4-4 4.4 WORK ZONE DEFINITION The three general work zones established at the Site are the Exclusion Zone, Decontamination Zone, and Support Zone. The Exclusion Zone is defined as the area where contam- ination is either known or likely to be present, or because of activity, will provide a potential to cause harm to personnel. Entry into the Exclusion Zone requires the use of personal protective equipment. The Decontamination Zone is the area where personnel conduct personal and equipment decontamination. It is essentially a buffer zone between contaminated areas and clean areas. Activities to be conducted in this zone include the removal of personal protection as explained in the decontamination plan (Section 4.5.1). The Support Zone is situated in clean areas where the chance to encounter hazardous materials or conditions is minimal. Personal protective equipment is therefore not required. 4.5 DECONTAMINATION PLAN 4.5.1 Personal Decontamination Procedures Decontamination procedures apply only to situations where level B and C protection has been implemented. The following decontamina- tion procedure shall be followed whenever exiting the exclusion zone. H&S/PALOHAR.04 4—5 Station 1 Segregated Equipment Drop Levels A, B, C • Deposit equipment used on site (tools, sampling devices and con- tainers , monitoring instruments, radios, clipboards, etc.) on plastic drop cloths or in different containers with plastic liners. Segregation at the drop reduces the probability of cross contamination. During hot weather operations, a cooldown station may be set up within this area. Remove tape around boots and gloves and deposit in plastic liner. Remove boot covers and deposit in plastic liner. Remove gloves and deposit in plastic liner. Wash hands, face and any other potentially contaminated areas with a potable water/mild soap solution followed by a potable water rinse. Shower and launder personal cloth- ing as soon as possible upon com- pleting daily activities. 4.5.2 Equipment Decontamination Procedures All equipment which comes into direct contact with potentially contaminated soil, surface water or groundwater shall be decontaminated prior to leaving the decontamination zone. Equipment decontamination procedures will consist of the following: Station 2 Tape Removal Levels A, B, C Station 3 Boot. Cover Removal Levels A, B, C Station 4 Glove Removal Levels A, B, C Station 5 Personnel Wash All Levels H&S/PALOMAR.04 4-6 LJ 1.

If the injury or illness is minor, full decontamination should be completed and first aid administered prior to transport. If the patient's condition is serious, at least partial decontamination should be completed (i.e., complete disrobing of the victim and redressing in clean coveralls or wrapping in a blanket.) First aid should be H&S/PALOMAR.05 5-3 administered while awaiting an ambulance or paramedics. All injuries and illnesses must immediately be reported to the Project Manager, Regional Health and Safety Coordinator and the Airport Manager. Any person being transported to a clinic or hospital for treatment should take with them a complete copy of this Site Health and Safety Plan. Any vehicle used to transport contaminated personnel will be treated and cleaned as necessary. 5.6.1 Fire or Explosion In the event of a fire or explosion, evacuate and contact the local fire department immediately. Upon their arrival, the Site Health and Safety Officer (HSO) or designated alternate will advise the fire commander of the location, nature, and iden- tification of the hazardous materials onsite. If it is safe to do so, site personnel may: • Use fire fighting equipment available onsite to control or extinguish the fire; and, • Remove or isolate flammable or other hazardous materials which may contribute to the fire. • If the Organic Vapor Analyzer indicates a reading of airborne contamination above 750 ppm, evacuate the area. 5.6.2 Spill or Leaks In the event-of a spill or a leak, site personnel will: • Inform the site supervisor immediately; • Locate the source of the spillage and stop the flow if it can be done safely; and, H&S/PALOMAR.05 5-4 • Begin containment and recovery of the spilled materials. • Contact the site owner as soon as possible. The site owner is responsible for notifying the appropriate authorities. 5.6.3 Emergency Equipment/Facilities The following emergency equipment will be kept in the field vehicle: • First Aid Kit • Fire Extinguisher • Site Telephone or Radio • Map of Evacuation Routes • Sorbent Materials/Foams H&S/PALOMAR.05 5-5 APPENDICES APPENDIX A FIRST AID/ACCIDENT REPORT FORM TIME OF ACCIDENT: DATE OF ACCIDENT: LOCATION OF ACCIDENT: DESCRIPTION OF ACCIDENT THAT OCCURRED: WAS PROPER SAFETY EQUIPMENT BEING UTILIZED?: YES NO LIST SAFETY EQUIPMENT BEING UTILIZED: FIRST AID ACTION TAKEN: SIGNATURE OF INJURED PARTY: DATE: FORM SUBMITTED TO (COUNTY): H&S/PALOMAH.A APPENDIX B DAILY RECORD OP HAZARDOUS WASTE FIELD ACTIVITY Site Name Period of Activities(Date) WA# Tasks Site Health & Safety Officer/Alternate Highest Airborne Conc./Monit.

In the event that respirators are deemed necessary for monitoring activities, the following are instructions on the proper care and maintenance procedures to be implemented. CLEANING AND DISINFECTING AIR PURIFYING RESPIRATORS (APR) APRs in routine use should be cleaned and disinfected at least daily. Where respirators are used only occasionally, or when they are in storage, the cleaning interval is weekly or monthly, as R appropriate. Lj Daily Cleaning Procedure The steps to be followed for cleaning and disinfecting daily are as follows: • Respirator Disassembly. Respirators are taken to a clean location where the filters, cartridges or canisters are removed, damaged to prevent accidental reuse, and dis- R carded. For thorough cleaning, the inhalation and ex- Li halation valves, speaking diaphragm, and any hoses are removed . • Cleaning. In most instances, the cleaning and disinfecting solution provided by the manufacturer is used, and is dissolved in warm water in an appropriate tub. Using gloves, the respirator is placed in the tub and swirled for a few moments. A soft brush may be used to facilitate cleaning. • Rinsing. The cleaned and disinfected respirators are rinsed thoroughly in water to remove all traces of deter- n gent and disinfectant. This is very important for preven- U j ting dermatitis. • Drying. The respirators may be allowed to dry in room air on a clean surface. They may also be hung upside down like drying clothes, but care must be taken not to damage or distort the facepieces. H8.S/PALOMAR.C C-l • Reassembly and Inspection. The clean, dry respirator facepieces should be resembled and inspected in an area separate from the disassembly area to avoid contamination. Special emphasis should be given to inspecting the respir- ators for detergent or soap residue left by inadequate rinsing. This appears most often under the seat of the exhalation valve, and can cause valve leakage or sticking. After Routine Use in Exclusion Zone The steps to be followed for cleaning and disinfecting in the field are as follows: • The mask may be washed/rinsed with soap and water. • At a minimum, the mask should be wiped with disinfectant wipes (benzoalkaloid or isopropyl alcohol), and allowed to air dry in a clean area. APR INSPECTION AND CHECKOUT 1. Visually inspect the entire unit for any obvious dam- ages, defects, or deteriorated rubber. 2. Make sure that the facepiece harness is not damaged. The serrated portion of the harness can fragment which will prevent proper face seal adjustment. 3. Inspect lens for damage and proper seal in facepiece. 4. Exhalation Valve - pull off plastic cover and check valve for debris or for tears in the neoprene valve (which could cause leakage). 5. Inhalation Valves (two) - screw off cartridges/canisters and visually inspect neoprene valves for tears. Make sure that the inhalation valves and cartridge receptacle gaskets are in place. 6. Make sure a protective cover lens is attached to the lens. 7. Make sure the speaking diaphragm retainer ring is hand tight. 8. Make sure that you have the correct cartridge. 9. Don and perform negative pressure test. H&S/PALOMAR.C C~2 STORAGE OP AIR PURIFYING RESPIRATORS OSHA requires that respirators be stored to protect against: Dust Sunlight Heat Extreme cold Excessive moisture Damaging chemicals Mechanical damage n Storage of respirators should be in a clean, secure area which U minimizes the chance for contamination or unsanitary conditions. r-, CLEANING AND DISINFECTING SELF CONTAINED BREATHING APPARATUS L-" Cleaning procedures for Self Contained Breathing Apparatus (SCBA) facepieces are identical to those for Ultratwin APRs. The backpiece H is cleaned with cleaning solution and a brush. Following cleaning, U the facepiece is combined with the regulator and an operational check is performed. n y SCBA INSPECTION & CHECKOUT p* Monthly Inspection LJ 1. Check cylinder label for current hydrostatic test date. 2. Inspect cylinder for large dents or gouges. 0 3. Inspect cylinder gauge for damage. 4. Complete routine inspection. 5. Fill out the appropriate records with results and n recommendations. Routine Inspection I Perform immediately prior to donning or after cleaning. 1. Before proceeding, check that the: U • High-pressure hose connector is tight on cylinder fitting. jj • Bypass valve is closed. ,-, • Mainline valve is closed. U • Regulator outlet is not covered or obstructed. H&S/PALOMAR.C C~3 2.

H&S/PALOMAR.C C~4 • Check regulator for leaks by blowing air into regulator for 5-10 seconds. Draw air from outlet for 5-10 seconds. If a positive pressure or vacuum cannot be maintained there is a leak. DO NOT USE SCBA. 5. Facepiece and corrugated breathing hose: n • Inspect hand harness and facepiece for damage, M serrations, and deteriorated rubber. LJ • Inspect lens for damage and proper seal in face- piece. Inspect exhalation valve for damage and dirt build-up. • Stretch breathing hose and carefully inspect for ( holes and deterioration. i * • Inspect connector for damage and presence of washer. • Perform negative pressure test with facepiece donned. 6. Storage: • Refill cylinder to 2216 psi. • Close cylinder valve. • Tightly connect high pressure hose to cylinder. • Bleed pressure from high pressure hose by opening mainline valve. • Close bypass valve. • Close mainline valve. • Fully extend all straps. • Store facepiece in a clean plastic bag for protection. j I HiS/PALOMAR.C C-5 u PERSONAL PROTECTIVE CLOTHING Inspection Proper inspection of PPE features several sequences of inspection depending upon specific articles of PPE and its frequency of use. The different levels of inspection are as follows:n • Inspection and operational testing of equipment received from the factory or distributor. • Inspection of equipment as it is issued to workers. • Inspection after use or training and prior to main- tenance. • Periodic inspection of stored equipment. • Periodic inspection when a question arises concerning the appropriateness of the selected equipment, or when problems with similar equipment arise. The primary inspection of PPE in use for activities at the Site will occur prior to immediate use and will be conducted by the user. This ensures that the specific device or article has been checked-out by the user, and that the user is familiar with its use. H&S/PALOHAR.C C-6 TABLE C.I PPE INSPECTION CHECKLISTS The PPE Inspection Checklist may change as a function^of the level of PPE for the site conditions. Reassessment of the Protection Program is described in Section 3.4.2 CLOTHING Before use: • Determine that the clothing material is correct for the specified task at hand. • Visually inspect for: Imperfect seams Non-uniform coatings Tears Malfunctioning closures • Hold up to light and check for pinholes. • Flex product: Observe for cracks - Observe for other signs of shelf deterioration • If the product has been used previously, inspect inside and out for signs of chemical attack: Discoloration Swelling - Stiffness During the work task, periodically inspect for: • Evidence of chemical attack such as discoloration, swelling, stiffening, and softening. Keep in mind, however, that chemical permeation can occur without any visible effects. • Closure failure. • Tears. • Punctures. • Seam Discontinuities. HiS/PALOMAR.C C~7 TABLE C.I (CONTINUED) GLOVES Before use: • Visually inspect for: Imperfect seams r~i - Tears, abrasions Non-uniform coating - Pressurize glove with air; listen for pin-hole leaks. NOTE ANY MODIFICATIONS TO THE LEVEL OF PROTECTION. H&S/PALOMAR.C C~8 APPENDIX D DIRECT-READING INSTRUMENTS The following is a list of some direct reading instruments typically used for general survey. It is anticipated that an FID will be used at Palomar, however other instrumentation is described in the event it is deemed necessary or useful to evaluated site conditions. 1. Instrument: Combustible gas indicator (CGI) Hazard Monitored: Combustible gases and vapors. Application: Measures the concentration of a combustible gas or vapor. Detection Method: A filament, usually made of platinum, is heated by burning the combustible gas of vapor. The increase in heat is measured. Gases and vapors are ionized in a flame. A current is produced in proportion to the number of carbon atoms present. General Care/Maintenance: Recharge or replace battery. Cali- brate immediately before use. Typical Operating Time: Can be used for as long as the battery lasts, or for the recommended interval between calibrations, whichever is less. 2. Instrument: Flame lonization Detector (FID) with Gas chroma- tography Option. Example: Foxboro OVA. Hazard Monitored: Many organic gases and vapors. Application: In survey mode, detects the concentration of many organic gases and vapors. In gas chroma- tography (GC) mode identifies and measures specific compounds. In survey mode, all the organic compounds are ionized and detected at the same time. In GC mode, volatile species are separated. H&S/PALOMAR. D D~l General Care/Maintenance: Typical Operating Time: Recharge or replace battery. Monitor fuel and/or combustion air supply gauges. Perform routine maintenance as described in the manual.

RUNWAY ENDS. Construction equipment normally should not penetrate the 20:1 approach surface. During inclement weather, a 50:1 approach surface is required. 2. RUNWAY EDGES. Construction activities normally should not be permitted within 200 feet of the runway centerline. However, construction may be permitted within 200 feet of the runway centerline on a case-by-case basis with approval of the airport operator, the FAA and the users. 3. TAXIWAYS AND APRONS. Normally, construction activity set-back lines should be located at a distance of 25 feet plus one-half the wingspan of the largest predominant aircraft from the centerline of an active taxiway or apron. However, construction activity may be permitted up to the taxiway and aprons in use provided that the activity is first coordinated with the airport operator, the FAA and the users; NOTAM's are issued; marking and lighting provisions are implemented; and it is determined the height of equipment and materials is safely below any part of the aircraft using the airport operations areas which might overhang those areas. An occasional passage of an aircraft with wingspan greater than 165 feet should be dealt with on a case-by-case basis. 4. EXCAVATION AND TRENCHES. a. Runways. Excavations and open trenches may be permitted up to 200 feet from the centerline of an active runway, provided they are adequately signed, lighted and marked. In addition, excavation and open trenches may be permitted within 200 feet of the runway centerline on a case-by-case basis, i.e., cable trenches, pavement tie- ins, etc., with the approval of the airport operator, the FAA and the users. b. Taxiwavs and Aprons. Excavation and open trenches may be permitted up to the edge of structural taxiway and apron pavements provided the drop-off is adequately signed, lighted and marked. 5. STOCKPILED MATERIAL. Extensive stockpiled materials should not be permitted within the construction activity areas i I | H&SVPALOMAR.H H-l U Excerpt From: AC 150/5370-2C 5/31/84 defined in the preceding four sections. 6. MAXIMUM EQUIPMENT HEIGHT. Notice of proposed construction shall be submitted to the appropriate Airports district office for review prior to the placement of construction equipment on airports. The guiding criteria involving FAR Part 139 certificated airports and grant agreement airports is that all construction plans and specifications required direct coordination with the appropriate Airports district, field, or regional office. In addition, airports should file FAA Form 7460-1 when equipment is expected to penetrate any of the surfaces defined above in paragraphs 1, 2, and 3. Airport operators are reminded that FAR Part 157 requires prior notice to construct, realign, alter, or activate any runway/landing area or associated taxiway for any project which is non- Federally funded. 7. PROXIMITY OF CONSTRUCTION ACTIVITY TO NAVIGATIONAL AIDS. Construction activity in the vicinity of navigational aids requires special consideration. The effect of the activity and its permissible distance and direction from the aid must be evaluated in such instance. A coordinated evaluation by the airport operator and the FAA is necessary. Technical involvement by FAA regional Airports, Air Traffic, Flight Standards, and Airway Facilities Specialists is needed as well as construction engineering and management input. Particular attention needs to be given to stockpiling materials as well as to the movement and parking of equipment which may interfere with line-of-sight from the tower or interfere with electronic emissions. (See AC 150/5300-2D, Airport Design Standards—Site Requirements for Terminal Navigational Facilities, current edition, for critical areas of NAVAIDS.) 8. CONSTRUCTION VEHICLE TRAFFIC. With respect to vehicular traffic, aircraft safety during construction is likely to be endangered by four principle causes: increased traffic volume, nonstandard traffic patterns, vehicles without radio communication and marking, and operators untrained in the airports' procedures. Because each construction situation differs, airport management must develop and coordinate a construction vehicle traffic plan with airport users, air traffic control and the appropriate construction engineers and contractors. This plan, when signed by all participants becomes- a part of the contract. The airport operator is responsible for coordinating and enforcing the plan. H&S\PALOMAR.H H-2 Excerpt From: AC 150/5370-2C 5/31/84 9. LIMITATION ON CONSTRUCTION. 10. a. Open-flame welding or torch-cutting operations should be prohibited unless adequate fire and safety precautions are provided and have been approved by the airport operator. All vehicles are to be parked^and serviced behind the construction restriction line and/or in an area designated by the airport operator. b. Open trenches, excavations, and stockpiled material at the construction site should be prominently marked with orange flags and lighted with flashing yellow light units (acceptable to the airport operator and the FAA) during hours of restricted visibility and/or darkness. Under no circumstances are flare pots to be near aircraft turning areas. c.Stockpiled material should be constrained in a manner to prevent movement result of aircraft blast or wind. Material should not be stored near aircraft turning areas or movement areas. MARKING AND LIGHTING OF CLOSED OR HAZARDOUS AREAS ON AIRPORTS. The construction specifications should include a provision requiring the contractor to have a man on call 24 hours per da? for emergency maintenance of airport hazard lighting and V^^v"-v"-i r-«^/^oebarricades. Permanently Closed Ru™*y* *"d Taxiwavs. For runways and taxiways which have been permanently closed, the lighting circuits should be disconnected. With runways, the threshold markings, runway designation marking, and touchdown zone markings should be obliterated and crosses should be placed at each end at 1,000-foot (300 m) intervals. With taxiways, a cross is placed at eacn entrance of the closed taxiway. Temporarily Closed Runway5 and Taxiwavs. Temporarily closed runways are treated in the same manner as in paragraph lOa except runway markings are not obliterated. Rather, crosses are usually of the temporary type (constructed of material such as fabric or plywood), and they are required only at runway ends. The crosses should be located on top of the runway numerals. For temporary marking, the dimensions of the crosses may be reduced to permit use of standard sheets of 4 x 8 foot (1.22 by 2.44 m) plywood. Temporarily closed taxiways are usually treated as an unusable area as explained in paragraph lOd. H&SVPALOMAR.H Excerpt. From: AC 150/5370-2C 5/31/84 c. Closed Airports. When all runways are closed temporarily, the runways are marked as in paragraph lOb, and the airport beacon is turned off. When all runways are closed permanently, the runways are marked as in paragraph lOa, the airport beacon is disconnected, and a cross is placed in the segmented circle or at central location if no segmented circle exists. d. Hazardous Areas. Hazardous areas, in which no part of an aircraft may enter, are indicated by use of barricades with alternate orange and white markings. The barricades are supplemented with orange flags at least 20 x 20 inches (50 by 50 cm) square and made and installed so that they are always in the extended position and properly oriented. For nighttime use, the barricades are supplemented with flashing yellow lights. The intensity of the lights and spacing for barricades, flags, and lights must be such to delineate adequately the hazardous area. e. Notices to Airmen (NOTAM's). The airport operator should provide information on closed or hazardous conditions to the local air traffic control facility (control tower, approach control, center, flight service station) so that a NOTAM can be issued. f. Stabilized Areas. Holding bays, aprons, and taxiways are sometimes provided with shoulder stabilization to prevent blast and water erosion. This stabilization may have the appearance of a full strength pavement but is not intended for aircraft use. Usually the taxiway edge marking will define this area, but conditions may exist such as stabilized islands or taxiway curves where confusion may exist as to which side of the edge stripe is the full strength pavement. where such a condition exists, the stabilized area should be marked with 3-foot (1 m) stripes perpendicular to the edge stripes. On straight sections, the marks should be placed at a maximum of 100-foot (30 m) spacing. On curves, the marks should be placed a maximum of 50 feet (15 m) apart between the curve tangents. The stripes should be extended to 5 feet (1.5 m) from the edge of stabilized area or to 25 feet (7.5m) in length, whichever is less. g. Runway Shoulder Marking. Usually the runway side stripes will indicate the edges of the full strength pavement. However, conditions may exist, such as exceptionally wide runways, where there is a need to indicate the area not intended for use by aircraft. In such cases, chevrons should be used. H&S\PALOMAR.H H~4 Excerpt From: AC 150/5370-2C 5/31/84 11. TEMPORARY RUNWAY THRESHOLD DISPLACEMENTS. Identification of temporary runway threshold displacements should be located outboard of the runway surface. These could include outboard lights, Runway End Identification Lights (REILS), and markings. The extent of the marking and lighting should be directly related to the duration of the displacement as well as the type and level of aircraft activity. H&S \PALOHAR.H H~5
