1. INTRODUCTION
As part of the City of Carlsbad Capital Improvement Program, the Vista Sewer/ Storm Drain
Project requires micro-tunneling operations through the City of Carlsbad. The micro-tunneling
operation was selected as the construction method of choice due to the relative non-disruptive
nature of the construction operation. The traditional method would be to cut-trench and backfill
thus disrupting service throughout the City. The primary alignment is via Jefferson Street with
several jacking pits located along Jefferson Street.
The City of Carlsbad hired Steve Bubalo Construction as the prime contractor for the pipeline
project. The initial micro-tunneling operation extended from Jefferson Street & Oaks Avenue to
Jefferson Street and Grand Avenue without incident. In early December, the tunneling operator
was moved to a jacking pit located at Jefferson Street & Arbuckle Place (2700 block of Jefferson
Street). The jacking operation was to proceed south along Jefferson Street to the Grand Avenue
terminus.
On December 12, 2001, during the tunneling operation the micro-tunneling staff noticed odor.
The site safety manager was contacted and ambient air monitoring using a PID was completed.
The City of Carlsbad Construction Manager was notified and soil and slurry samples were
immediately gathered and sent a local certified laboratory (HP Labs). Tunneling operations were
terminated pending laboratory results and further direction from outside consultants.
On December 13, 2001, laboratory results were provided indicating relatively low levels of
volatile organic compounds and total hydrocarbons. Although the soil and water results were
below site assessment levels, and the odor may have been from a localized pocket, it was
recommended to complete and implement a Community Health & Safety Plan as a conservative
public protection step by the City. The Community Health & Safety Plan will be in accordance
with the Department of Environmental Health- Site Assessment Manual (SAM) guidelines.
2. TUNNELING OPERATION
On December 17, 2001, the tunneling operation continued with the Community Health & Safety
Plan (Appendix A) in place, Contractor H&S training, and additional jacking pit ventilation
equipment provided. DHK Engineers provided community ambient air monitoring at 11 perimeter
locations using an Organic Vapor Analyzer (OVA) during the entire day. The contractor's Site
Safety Supervisor monitored work safety areas during the day.
The jacking operation installed approximately 50 feet of pipe (sticks 9-10-11). All soil was
trucked to the spoil pile area designated as temporarily storage until a soil characterization is
completed. The community monitoring field report is provided in Appendix B.
3. SOIL EVALUATION
The soil removed from the tunneling operation was trucked to a City of Carlsbad Stockyard
located adjacent to the railroad tracks along the south-end (off of Taramack) of the City of
Carlsbad Project. The soil identified as "unknown odor" was isolated from other stockpiles. The
special stockpile had a visqueen base and visqueen cover at all times. Prior to final disposition of

the soil, spoil pile sampling will be conducted in accordance with the SAM using EPA 8015 full
range analytical methods and Method 8260B. The sample ID is associated with the pipe segment
number.

3. PLOT PLAN
The tunneling pit and soil separation facility is located in close proximity of residential and
commercial. The jacking pit is within 50 feet of a business (2777 Jefferson Street) and the soil
separation is within 25 feet of the closet resident (750 Arbuckle Place). Figure 1 illustrates the
potential receptors in the immediate area. Local traffic along Jefferson Street is within 10 feet of
the jacking pit.
4. EVALUATION OF POTENITAL PUBLIC EXPOSURE TO HAZARDS
The City of Carlsbad as part of the pre-design effort evaluated the potential exposure to the
receptors including noise, dust and physical hazards. In review of the alignment along Jefferson
Street, no identified UST facilities were within the zone of influence. Due to noise, dust and
physical hazards, micro tunneling was selected as the most environmentally "friendly"
construction technique. Little soil disruption would be required and the noise locations would be
centralized allowing sound attenuation provisions to be implemented.
The jacking pit operations has primarily two areas which the soil / slurry is exposed to the
environment. The jacking pit pushes a 20-foot segment of pipe through the opening bore by the
jacking device. Slurry is used to convey the soil from the tunnel to the soil separation unit. The
slurry is dewatered and the soil is removed and disposed, and the water reused in the boring
operation.
During each pipe segment set-up, the slurry lines are uncoupled and re-attached. During the re-
attachment process some of the slurry water is discharged to the jacking pit sump. If
hydrocarbons were present, the hydrocarbons would potentially off-gas within the jacking pit
area. Worker awareness and adequate personnel protective equipment is required by OSHA. The
worker safety requirements are not part of the PLAN. The jacking pit floor is approximately 10
feet below street elevation and the public could be exposed if vapors were present in sufficient
quantity as to fill the pit.
The slurry separation area removes the soil from the boring slurry. If the slurry comes into contact
with the contaminated soil, the potential exists of conveying the contamination via to the slurry to
the soil separation facility. The slurry separation facility is adjacent to southwest corner of
Jefferson Street and Arbuckle Place. The slurry separation facility is partially shrouded by a
sound blanket to abate the noise.
4. MONITORING EQUIPMENT
The City/Contractor will provide an on-site site safety supervisor. The Site Safety Supervisor
(SSS) will be equipped with a Photo lonization Detector (PID) for monitoring VOC and
hydrocarbon related compounds. The PID will be calibrated daily and the calibration recorded.
Prior to start of work, the SSS will conduct a perimeter survey. Upon start-up and within the first
60-minutes, the SSS will conduct a follow-up survey. A survey will be completed once an hour
throughout the day for project documentation.
DHK ENGINEERS, INC ? Project No. 3182/3528
COMMUNITY HEALTH & SAFETY PLAN Jefferson Street/Arbuckle Hace DECEMBER 2001
The pit perimeter will be monitored during the slurry line re-attachment process. The SSS will
have the authority to stop traffic along Jefferson Street if jacking pit vapors are present.
The records will be maintained and made available for on-site review at the request of Department
of Environmental Health or other regulatory agencies.
5. CONTROL METHODS
a. Site Security: The construction site will be fenced to restrict access around the jacking pit
and slurry separation facility. Local traffic will be restricted to the fullest extent possible.
b. Vapors/Odors: Vapor monitoring will the generation of VOC latent air. Air dispersion
fans will be located within the jacking pit. The slurry separation facility is partially
enclosed by a sound blanket. The soil will removed from the site and stock piled in a
secure location downwind of receptors.
c. Dust: The construction process minimizes the potential dust generation and dispersion.
The soil (moist condition) is trucked to a stockpile area and covered with visqueen. The
equipment is washed down each evening prior to departing the site.
d. Noise: A noise assessment, sound attenuation and site certification is in place in
accordance with the City Contract specifications.
e. Open Excavation: The jacking pit is approximately 15' wide by 30' long by 10' deep
located in the southbound lane of Jefferson Street. The jacking pit was installed in early
December and is properly secured.
f. Stockpiled Soil: The soil removed from the tunneling operation is trucked to a City of
Carlsbad Stockyard located adjacent to the railroad tracks along the south-end (off of
Taramack)of the City of Carlsbad Project. The soil identified as "unknown chemical
odor" will be isolated from other stockpiles. The special stockpile will have a visqueen
base and visqueen cover at all times. Prior to final disposition of the soil, spoil pile
sampling will be conducted in accordance with the SAM using EPA 8015 full range
analytical methods.

7. EMERGENCY PLANNING
The construction site is equipped with several cellular phones with fire department contact
numbers: 911
In the event of a large vapor release or liquid pooling, the tunneling operation will immediately
stop. Traffic along Jefferson Street will be halted and the Contractor shall go door to door within
one block notifying the residences or business owners of the potential threat. The SSS will
contact the fire department.
8. PUBLIC NOTIFICATION
Prior to the construction of the jacking pit, the Contractor notified the surrounding area of the
construction project and provided each residence and business a point of contact. A revised
Public Notification Form will be developed and distributed to the surrounding residents and local
businesses.
The PUBLIC NOTICE will be mounted on the project perimeter along each fence.

Mark and Rick:
Per our discussions, we received the laboratory results from the six soil samples taken on
December 20, 2001.
Piles S-8 and S-12 are to be placed back in jacking pit within 2 feet of surface. Both piles are
greater than 50-ppm diesel but less than 100-ppm (Method EPA-8015M).
Piles S-13 and S-9 are to be placed within an excavation anywhere on the project- > 1 foot below
surface. Both piles are between 25-ppm and 50-ppm.
Piles S-15 and S-17 are unrestricted as both were non-detects!
ALL SAMPLES WERE NON-DETECT FOR ALL CHEMICALS EPA- 8260B! (Excellent!)
I'll summarize the laboratory results, community monitoring and other project related information
in a letter report format for your files.

SECTIONS: SITE INVESTIGATION TECHNIQUES
A. Sampling Protocol for Stockpiled Soil
1. Stockpiled soil that is designated tor disposal to a permitted hazardous waste or specified
waste facility, or to a treatment/recycling facility, must be sampled and analyzed in
accordance with the receiving facility's requirements. These facilities may havu different
requirements than those presented below. Copies of all laboratory data and hazardous waste
manifests, or other transportation documents generated for the soil treatment or disposal,
must be submitted to DEH to demonstrate the proper handling and disposal of contaminated
soil.
2. DEH will not accept composite soil samples for characterizing contaminated soil stockpiles.
Only discrete samples will be accepted, because of the losses of volatile contaminants during
sample handling and the dilution of non-volatile contaminants.
3. All stockpiled soil associated with an unauthorized release, spill, or other release that is not
intended to be transported affsite to a permitted facility, or has not been previously
characterized through in situ sampling, must be sampled in accordance with the protocol
outlined below. Tills protocol provides a uniform approach for demonstrating the
contaminant level within a soil mass. Prior approval must be obtained from DEH and the
RWQCB for off-site transport or reuse on-site of any soil associated with an unauthorized
release, spill, or other release, including soil taken from areas of the site outside of the spill or
release.
4. Procedures in EPA Publication SW-846 provide a method for determining the mean
concentration of a given contaminant within a soil mass and the appropriate number of
samples necessary to calculate this mean to within a specified confidence level. Initial
sampling should generate a minimum number of samples/analyses as described below.
Additional sample analyses may be required to meet the confidence levels given in SW846;
therefore, archiving of samples may be appropriate. Archived samples must be appropriately
preserved and analyzed within the maximum holding time specified In SW-846. The
minimum number of discrete samples initially required is given below:
• Stockpiles less than 10 cubic yards: a minimum of two (2) samples must be collected, one
from each half of the stockpile. Select sample points randomly within each half.
• Stockpiles from 10-20 cubic yards: a minimum of three (3) samples must be collected,
one from each third of the stockpile. Select sample points randomly within each third.
• Stockpiles from 20-100 cubic yards: a minimum of four (4) samples must be collected,
one from each quarter of the stockpile. Select sample points randomly within each
quarter.
• Stockpiles from 100-500 cubic yards: a minimum of one (1) sample for each 25 cubic
yards or portion must be collected (e.g., ft 130-cubic yard stockpile would require 6
samples). Section the stockpile into 25 cubic vard portions and obtain a minimum ofone
(1) sample from each 25 cubic yard portion. Select sample points randomly within each
25 cubic yard portion of the stockpile.

« Stockpiles over 500 cubic yards: contact DEH for guidance on the minimum samples
necessary.
5. Random sample points must be selected from locations on a three-dimensional grid. The
presence of materials such as boulders, debris, etc., may make strict application of this
requirement impractical. In such cases, it is appropriate to obtain the sample as close as
possible to the randomly selected point without altering the spirit of the random selection
process. For hydrocarbon contaminants, sample collection in cither metal tubes or glass jars
is acceptable, provided every effort is made to minimize the loss of volatile constituents.
Metal tubes are preferred, since thoy will minimize aeration of the samples. Containers
should be completely filled, capped, and placed on ice immediately.
6. Stockpiled soil is assumed to have a non-homogeneous distribution of contaminants. If a
stockpile previously characterized by this protocol is split for any reason (such as to excise a
portion expected to be highly contaminated from a non- or lesser-contaminated portion), the
remaining mass must be re-sampled as a new stockpile per the previously described protocol
to establish its mean contaminant concentration. Note that it is not necessary to consider each
individual stockpile separately. At the discretion of the consultant, stockpiles expected to
contain similar contaminant conditions can be considered part of the same soil mass for die
purpose of SW-846 sampling.
7. Information on stockpiled soil evaluation must be submitted to DEH and must include the
following:
An estimate of the volume of contaminated soil involved
A description of the contaminant (e.g., gasoline, diesel, aviation fuel)
A description of the sampling methodology and the sample location/selection process
A plot plan detailing ihe stockpile and sample locations
A copy of all sample results, chain of custody documents, and QA/QC supporting dam
A one-page summary of the laboratory results for the stockpile sampling
Statistical calculations for ail stockpiles greater than 20 cubic yards. Note: A Stockpile
Statistics Worksheet (Table 5-8) and Tabulated Values of Students 't5 (Table 5-9) are
provided as an aid in completing those calculations.
• A statement by the RP or by a registered professional (e.g., RG. RCE, Registered
Environmental Health Specialist, or equivalent) certifying the level of contamination as
determined using the SW-846 statistical process.
8. Data generated by field instrument methodologies such as photo-ionization and flame
ionization Selectors are not acceptable for quantifying contaminant concentrations.

B. Sampling Protocol for Containerized Soil
The RP or consultant often chooses to manage soil by placing it in containers (e.g., storage bins,
55-gallon drums) for security or aesthetic reasons. The characterization of soil placed in storage
bins will typically follow the same sampling protocol as described above for stockpiled soil.
However, the characterization of soil placed hi drums may require the review of boring logs and
site sampling/analytical data, as well as the collection of soil samples from selected drums.
Please contact me DEH caseworker For specific direction concerning the characterization of soil
stored in drums.y
