Palomar Airport Landfill
Methane Monitoring Of City Water Line Excavation
March 15 Through 17 1993
SCOPE OF WORK
The scope of work for M&E called for monitoring of methane gas
during the excavation for the 10" water supply line and the 6"
water service line. 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.
Sincerely,

READING REMARKS
Q
Power is provided with rechargeable nickel
cadmium batteries providing up to 10 hours of
continuous operation without recharging.
The electronics for each instrument are solid
state and are microprocessor controlled pro-
viding "state-of-the-art" design.
The Liquid Crystal Display (LCD! provides:
a) the digital display of percent Lower Flam-
mable Limit in air of the specified combusti-
ble gas or;
b] the digital display of percent oxygen in air,
(whichever is selected). The selected varia-
ble legend (°/o LFL or °/o Og) is also shown.
The display can be momentarily illuminated for
poorly lighted areas.
The following alarm or operation legends will be
displayed as appropriate.
"ALARM" - Flashing legend indicates:
a) high gas or vapor concentration which
exceeds a pre-set level, (factory set at 25%).
(b) low or high oxygen concentration which
exceeds a pre-set level, (factory set at
1 9.5°/o and 25.0%).
"LOBAT" - Flashing legend indicates the bat-
teries are low.
NOTE: Legend will start to flash when 10 per-
cent (approximately 1 hour) of battery life
remains. At the end of the useful battery life
the audible alarm will sound, and all other indi-
cations will be blanked.
"FAIL" - Flashing legend indicates a sensor or
electronic failure or a below 10°/o oxygen con-
centration.
"HOLD" - Legend indicates the "HOLD" switch
has been depressed, and either the highest
indication for °/o LFL or the lowest indication of
°h Og will be retained until the instrument is:
a) turned OFF; or
b) the "HOLD" switch is again depressed; or
c) the selected display (°/o LFL or °/o Og) is
changed to the other display.
As previously stated, an audible alarm is pro-
vided for the following alarm conditions:
"ALARM" -
a) High gas or vapor concentration.
b) Low or high oxygen concentration.
The audible alarm provides a latching fast pulse
rate tone which can only be re-set by turning
the instrument "OFF" and then "ON" in an
atmosphere below the pre-set combustible
gas or vapor alarm level or between the high
and low pre-set oxygen alarm levels.
"LOBAT" - Batteries are low and the instru-
ment is no longer usable. Alarm provides a slow
pulse rate tone.

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.

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.

Dust may evolve from the site or nearby area, gases may be emitted
from the site. 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.
General Descriptions

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.
Phase work, if necessary, to facilitate airport
activities. ;—

*J protection required for remedial activities at the Site.
nLJ 3.4.1 Levels of Protection
nI Described below are specific levels of protection and necessary
components for each four categories according to the degrees of-'"•)protection afforded. 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.

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.

APPENDIX C
PPE INSPECTION PROCEDURES
Level D protection, which is currently proposed for PAL, does not
include the use of air purifying respirators. 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

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.

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. Check
for leaks.
8 hours; 3 hours with strip chart
recorder.
3. Instrument: Portable Infrared (IR) spectrophotometer
Hazard Monitored: Many gases and vapors.
Application: Measures concentration of many gases and
vapors in air. Designed to quantify one or two
component mixtures.
Detection Method:Passes different frequencies of IR through the
sample. The frequencies absorbed are specific
for each compound.
General Care/Maintenance:As. specified by manufacturer.
4. Instrument: Ultraviolet (UV) Photoionization Detector (PID)
Example: HNU.
Hazard Monitored:
Application:
Detection Method:
Many organic and some inorganic gases and
vapors.
Detects total concentration of many organic
and some inorganic gases and vapors. Some
identification of compounds are possible if
more than one probe is measured.
Ionizes molecules using UV radiation; produces
a current that is proportional to the number
of ions.
General Care/Maintenance:Recharge or replace battery. Regu-
larly clean lamp window. Regularly
clean an maintain the instrument and
accessories.
Typical Operating Time: 10 hours. 5 hours with strip chart
recorder.
H&S/PALOMAR.D D-2
5. Instrument: Direct Reading Colorimedicating Tube
Hazard Measured: specific gas and vapors.
Application: Measures concentration of specific gases and
vapors.
Detection Method: The compound reacts with the indicator chemi-
cal in the tube, producing a stain whose
length or color change is proportional to the
compound's concentration.
General Care/Maintenance: Do not use a previously opened tube
even if the indicator chemical is
not stained. Check pump for leaks
before and after use. Refrigerate
before use to maintain a shelf life
of about 2 years. Check expiration
date of tubes. Calibrate pump vol-
ume at least quarterly. Avoid rough
handling which may cause channeling.
6. Instrument: Oxygen Meter
Hazard Monitored: oxygen (02)
Application: Measures the percentage of 02 in the air.
Detection Method: Uses an electrochemical sensor to measure the
partial pressure of 02 in the air, and con-
verts that reading to O2 concentration.
General Care/Maintenance: Replace detector cell according to
manufacturers recommendations. Re-
charge or replace batteries prior to
expiration of the specified inter-
val. If the ambient air is more than
0.5% CO2, replace the detector cell
frequently.
Typical Operating Time: 8-12 hours.
H&S/PALOMAR.D D~3
7. Instrument: Real Time Aerosol Monitor
Hazard Monitored: Particulates
Application: Measures total particulates in air.
Detection Method: Uses an internal light source. The par-
ticulates defract the light beam and the
amount of diffraction is converted into con-
centration (mg/m3).
General Care/Maintenance: Recharge batteries. Replace desic-
cant when necessary.
Typical Operating Time: 8-12 hours.
8. Instrument: Monitox
Hazard Monitored: Gases and Vapors
Application: Measures specific gases and vapors
Detection Method: Electrochemical sensor relatively specific for
the chemical species in question.
General Care/Maintenance: Moisten sponge before use; check the
function switch; change the battery
when needed.
9. Instruments: Gamma Radiation Survey Instrument
Hazard Monitored: Gamma Radiation
Application: Environmental radiation monitor
Detection Method: Scintillation detector
General Care/Maintenance: Must be calibrated annually at a
specialized facility.
Typical Operating Time: Can be used for as long as the bat-
tery lasts, or for the recommended
interval between calibrations,
whichever is less.

SPECIAL SAFETY REQUIREMENTS DURING CONSTRUCTION
1. 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.

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.
