EXHIBIT "A"
AMENDED SCOPE OF SERVICES
1 Subtask 3b. Methane Gas Assessment To evaluate the presence of methane gas and other
gases typically associated with decomposition of septic waste, the installation of three soil
vapor probes per septage pond at the depth of 5 feet bgs in each of the aforementioned
exploratory borings, for a total of 15 soil vapor probes All soil vapor proves installed will
be screened in the field for methane using a 4 -gas meter
Soil vapor probes will be installed usmg a Geoprobe direct push rig Soil vapor probes will
be installed in accordance with the California Environmental Protection
Agency/Depaitaient of Toxic Substance Control (DTSC) Active Soil Gas Investigations
Advisory, July 2015 The use of this protocol ensures that the sampling procedures and
analytical methods meet the stringent DTSC guidehnes During the sampling procedures,
vacuum mtegnty of the sampling system is tested pnor to and after the soil gas sample is
collected Leak -down testing is conducted to determine vacuum integrity During
sampling, for safety purposes, the Consultant shall continuously monitor the site using a
photoiomzation detector (PID) and a four -gas meter
Additionally, per the Regional Water Quality Control Board's request, carcinogenic
volatile organic compounds (VOCs) will be added to the list of analytes for samples
collected from the soil vapor probes as part of the soil gas assessment for the septage ponds
A mobile laboratory will be used to collect the soil gas samples and analyze onsite Field
work will be extended from the ongmal estimate of one day to two days
2 Subtask 3c Fire Suppression Discharge To evaluate new waste discharge that may have
occurred as a result of fire suppression, the Consultant shall collect soil samples from each
of the soil vapor probe bonngs using the Geoprobe rig Soil samples will be collected from
0 5 feet and 5 feet bgs from the 15 boring locations completed for the Methane Gas
Assessment Soil samples will be collected using either a Geoprobe or a hand auger and
stored m glass jars provided by the analytical laboratory Each end of the sample will be
covered with a Teflon sheet and a tight -fitting plastic cap Soil samples will be placed on
ice pending delivery to a state -certified laboratory under chain -of -custody protocol
Initially, the fifteen 0 5 -foot soil matrix samples will be analyzed for PFAAs, and the
deeper samples will be held pending the results If it is determined that analysis of the
deeper samples is warranted, the Consultant shall test a maximum of one per septage pond
If further testing is warranted the Consultant shall discuss the additional cost with the City
In addition, per the Regional Water Quality Control Board's request, a laboratory will be
used that will analyze the samples for Perfluorinated Alkyl Acids (PFAAs) following the
Department of Defense (DOD) protocols as part of the assessment of the effect of fire
suppression foam on the septage ponds The drilling company will use additional levels of
decontamination protocols
