Updated Task 2 Work Order
Targeted Reduction of Residual LNAPL- Nutrient Enhanced Biological Simulation Pilot
Study
Dear Bill Preston:
Haley&Aldrich, Inc. (Haley&Aldrich) is pleased to submit this proposal for engineering and
environmental services in connection with the above-referenced site(the Site).The updated Task 2
Work Order is comprised of tasks requested by the City of Yakima (City)and the Washington State
Department of Ecology(Ecology).
Scope of Services
A pilot study is proposed for targeted reduction of residual light nonaqueous-phase liquid (LNAPL)at the
Site(Ecology Facility Site No. 469, Cleanup Site No.4919, located at 2312 West Nob Hill Boulevard, in
Yakima, Washington; refer to Figure 1) involving nutrient-enhanced biological stimulation (NEBS)
remedial technology.This technology,developed by the U.S. Department of Energy in concert with the
Savannah River Technology Center in 1995, uses PHOSter nutrient injection technology, as well as air
and gas-phase nutrients,to promote cell division of indigenous microbes to sufficient numbers to
quickly oxidize carbon-based contaminants such as petroleum hydrocarbons and chlorinated solvents.
The gas-phase nutrient injections are injected as pulsed air sparges with controlled dosages of
air/oxygen, nitrous oxide,triethyl phosphate,and methane/propane/butane.The indigenous microbes
use the injected air and nutrients to aerobically degrade petroleum contamination, reducing the mass of
petroleum hydrocarbons and associated volatile organic compounds(VOCs; benzene,toluene,
ethylbenzene, and xylenes [BTEX])and producing biomass, carbon dioxide, and water.

An overview of the scope of services for Task 2 is as follows:
• Prepare a Targeted Reduction of Residual LNAPL—NEBS Pilot Study scope of services, budget
estimate,coordination plan, and project logistics.
• Conduct data analysis and discussions of the preliminary findings from the QuantArray-Petro
and QuantArray-Chlor microbial analyses.
• Attend Task 2 Kick-Off Meeting at the City office.
• Prepare an Underground Injection Control (UIC) registration application, injection data packet,
and obtain a UIC permit.
• Drill/install three NEBS injection wells(refer to Figures 2 and 3).
• Conduct the NEBS pilot study,which will be an active remediation treatment for the targeted
area, at the Site for four months. Smith Monitoring&Maintenance Engineering, Inc. (SMME)
will lead the operations, maintenance,and monitoring(OM&M) of the NEBS remedial system.
• Conduct monthly OM&M activities on the NEBS system to tailor the remediation nutrient
analysis and its use in nutrient dosage control and evaluate key geochemical and groundwater
quality parameters.
• Conduct a post-NEBS pilot study groundwater monitoring event within approximately one
month after the completion of the NEBS pilot study to collect groundwater samples from the
Site's network of 17 compliance monitoring wells for the Site's constituents of concern (COCs).
Analyze specific groundwater samples (from YMW-1,S-1, S-2,and KMW-6; refer to Figure 2)
within the treatment zone using QuantArray-Petro and QuantArray-Chlor microbial analyses to
compare the data findings of before-and after-NEBS remedial action impacts on the types of
bacteria that can express enzymes used in oxidation or reduction of the targeted petroleum
contaminant and an understanding of the existence of microbial community within the
subsurface. Laboratory analytical results and findings from the baseline groundwater monitoring
event and follow-up groundwater monitoring event will provide the necessary data for analyzing
the impacts and benefits of the NEBS pilot study.
• Prepare the Targeted Reduction of Residual LNAPL NEBS Pilot Study Report.
• Manage investigation-derived waste (IDW-soil cuttings and purged groundwater) by containing
in 55-gallon drums,storing on Site, and disposing of in one pickup and disposal event.
Assumptions:
• The Kick-Off Meeting,to be held in person,will take place at the City Office.A Site walk for the
Haley&Aldrich and SMME team will be conducted following the Kick-Off Meeting to evaluate
the Site logistics for the NEBS remedial system,electrical requirements,and system set up,
operation, and OM&M.
• Site access will be provided for drilling and installation of three NEBS injection wells (IW1
through IW3; refer to Figure 2).

• The UIC permit will be issued by Ecology within approximately four to six weeks after submittal
of the UIC Work Plan and/or be provided no later than January 2024 in order to provide
adequate notice for the timing required to construct the tailored NEBS remedial system for the
Site and for the remaining site logistics, including electrical permitting, site access, kick-off
meeting, shipping of the NEBS remedial system, NEBS pilot study operations start up, and
scheduling of the monthly OM&M tasks.
• Monthly progress reports will be provided for the four months of the active NEBS remediation
operations and two months after the active remediation pilot study period. Note: progress
reports will be provided on a quarterly basis for the subsequent six quarterly periods during the
quarterly groundwater monitoring and sampling events phase of work.The scope of services
and budget estimate for the quarterly groundwater monitoring events task will be provided in a
separate task work order.
• Usage and operation of the recently installed electrical power pole will be available during the
sub-slab depressurization pilot test.An electrical power service rated for either 240-or 208-
volt/single-phase/60-amp service connection will be obtained.An estimate of power use is a
maximum of 1,500 kilowatts per hour per month.
• The monthly OM&M activities will involve groundwater monitoring/sampling at three selected
designated monitoring wells (YMW-1,S-1,and S-2)to evaluate key geochemical parameters
(nitrate,orthophosphate,ferrous iron, and alkalinity)and groundwater quality parameters.The
findings from this set of data will be evaluated for the tailoring of nutrient dosages applied
during the NEBS pilot study.
• Project status conference calls will be held on an as-needed basis.
