1.2.1 Facility Locations and descriptions

FORMER DFSP WHITTIER, AK FACILITY DESCRIPTION

The Whittier terminal is located on a delta and moraine deposits along the shoreline of the Passage Canal. The site is approximately 60 miles southeast of Anchorage and is now accessible by highway vehicles as well as by water or train. The major terminal facility is the former tank farm located one mile west of the town of Whittier. The tank farm covers about 85 acres and originally consisted of 13 aboveground tanks, a pump station, and a railcar loading rack. All terminal operations were closed in 1996 and the infrastructure has been removed. Some above-ground pipeline remains as well as the tank pads and berms. The site is fenced in most places; fencing is not required as part of the remedial plan.

The site characterization and remedial actions included steam-sparging and soil excavation efforts. A long-term monitoring program is in place and the active remediation system using bioventing was installed in 2018-2019. The bioventing system is off-Army lands and on Alaska Railroad Corporation (ARRC)-owned lands. The Government has a right of entry permit with the ARRC. The former tank farm property is currently owned by the US Army and has been mandated to transfer directly to the City of Whittier via Public Law. At the time of this document, negotiations to transfer the property are just beginning.Access to the site by the Government will be retained in the property transfer documentation.

3.10 Task 10 – Whittier Summer/High Groundwater Monitoring Events

The Contractor shall perform groundwater monitoring at the former DFSP Whitter site annually when groundwater is considered at a “high” level. Historically, high groundwater monitoring is conducted when groundwater elevations are approximately 10 feet above mean sea level or higher at monitoring well MW-30.

Actual sampling date will be dependent on groundwater levels; this Task is scheduled as a high groundwater event that has historically been conducted in the ~August-October timeframe. Two water level measurement events shall be taken in advance to determine the optimal sampling event timeframe as noted below. Work shall be performed as it has been conducted in the past (latest Work Plan and Final report will be provided) and in accordance with (IAW) ADEC regulations and guidance.

Phase 1: Planning: The Contractor will prepare a Draft Work Plan (WP) for each summer/high groundwater sampling event. The WP will document procedures to be utilized as part of the groundwater sampling activities to be performed in accordance with historical procedures, ADEC regulations and guidance, and the Decision Document.

The Contractor shall provide the draft WP to the COR (assume 10 days for DLA approval). Upon revision of DLA comments and approval, DLA will forward the DLA-approved Draft documents to ADEC for their review and comments, and allow for a thirty-day review period. The Contractor will finalize the report within 30 days after receipt of review comments and approval by the COR and ADEC, and submit one (1) electronic copy and one (1) CD-R media copy of the Final for ADEC to the COR. All copies shall be submitted to DLA; DLA will forward any deliverables to ADEC.

The Contractor shall provide a tentative schedule of deliverables and field actions in the proposal and submit a final schedule within ten (10) business days of task award.

Phase 2: Sampling Event/Analyticals Submission: Following approval of the WP by the COR and ADEC, the Contractor will mobilize to the Site twice to collect groundwater elevation data to verify the optimal timing for the sampling event. It is anticipated that the high groundwater sampling event will be conducted in the ~August-October timeframe.

The following technical approach will generally be utilized by the Contractor to execute the sampling event:

• Mobilize to clear trail, since area is undeveloped and access to monitoring wells may require clearing.

• Once the optimal groundwater level has been recorded in line with past high groundwater monitoring events:

o Up to 32 wells will be gauged for free product and depth to water measurements (DTW) utilizing a groundwater interface probe; and o Up to 32 monitoring wells will be sampled utilizing various techniques as appropriate and historically completed, and set forth in the approved WP, to assist in providing more reproducible data. The use, when possible, of an inflatable packer deployed within a monitoring well to segregate portions of the screened interval and/or limit the rate of vertical flow.

Sample collection methods for the 32 wells are presented below:

• Up to 17 monitoring wells will be sampled utilizing low-flow sampling methodologies;

• Up to 9 monitoring wells will be sampled utilizing low-flow sampling methodologies with an inflatable packer; and

• Up to 6 monitoring wells will be sampled using HydraSleeve samplers.

Quality assurances/quality control (QA/QC) samples will be collected and analyzed by the Contractor in accordance with ADEC Field Sampling Guidance and as set forth in the approved WP. QA/QC samples shall include standard QC samples, such as field rinsates, trip blanks, duplicates and MS/MSD samples collected during each event.

Laboratory analyses shall be performed as specified in the facility groundwater monitoring plan.

The Contractor will treat purge water generated during sampling activities on-site utilizing granular activated carbon

(GAC).

The groundwater samples will be submitted to an appropriately approved lab for the following parameters to be performed as groundwater monitoring events have historically been conducted:

• Diesel Range Organics (DRO) via AK102;

• Residual Range Organics (RRO) via AK103;

• Gasoline Range Organics (GRO) via AK101;

• Lead via Method 6020;

• Volatile Organic Compounds (VOCs) via Method 8260B; and

• Polynuclear Aromatic Hydrocarbons (PAH) via Method 8270-SIM

Following receipt of the analytical data from the Lab, the data will be validated by the Contractor’s chemist. The Contractor will submit Chain-of-Custody documentation with its invoice.

Phase 3: Reporting:

Within 30 days following receipt of analytical data, the Contractor will submit an electronic draft of the Monitoring Report to the COR for review. The report will document the groundwater sampling event IAW ADEC and guidance and historical site Reports. The Contractor shall provide the draft Report to the COR (assume 10 days for DLA approval). Upon revision of DLA comments and approval, DLA will forward the DLA-approved Draft documents to ADEC for their review and comments, and allow for a thirty-day review period. The Contractor will finalize the Report within 30 days after receipt of review comments and approval by the COR and ADEC, and submit one (1) electronic copy and two (2) CD-R media copies of the Final for ADEC to the COR. All copies shall be submitted to DLA; DLA will forward any deliverables to ADEC.

Phase 4: Additional Insurance Requirements: In accordance with the ARRC Right-of-Way Permit, the following additional insurance coverage is required by the Contractor to sample monitoring well locations within 50 feet of the railroad tracks:

a. Commercial General Liability insurance with limits not less than $5,000,000 per occurrence and $10,000,000 aggregate for Bodily Injury and Property Damage, including coverage for Premises and Operations Liability, Products and Completed Operations Liability, Contractual Liability, and Broad Form Property Damage Liability. Coverage shall not contain any exclusions for Explosion, Collapse, Underground, Rail Operations, or Work on Railroad Property.

b. Automobile Liability insurance on all owned, non-owned, hired and rented vehicles with limits of liability of not less than $1,000,000 Combined Single Limit for Bodily Injury and Property Damage per each accident or loss.

c. Worker's Compensation insurance in accordance with the statutory coverages required by the State of Alaska and, where applicable, insurance in compliance with any other statutory obligations, whether State or Federal, pertaining to the compensation of injured employees assigned to the Work, including but not limited to Voluntary Compensation, Federal Longshoremen and Harbor Workers Act, and the Federal Employers Liability Act.

d. If any part of the work to be performed on ARRC Property is located within fifty feet (50’) of a railroad track, then the Permittee shall also obtain Railroad Protective Liability Insurance (Alaska Railroad Corporation as named insured) with limits of liability of not less than $5,000,000 Combined Single Limit for Bodily Injury and Property Damage per each accident or loss.

3.11 Task 11 – Whittier Winter/Low Groundwater Monitoring Events

Groundwater monitoring is conducted at the former DFSP Whitter site annually when groundwater is considered at a “low” level. Historically, low groundwater monitoring is conducted when groundwater elevations are approximately 10 feet below mean sea level or lower at MW-30.

Actual sampling date will be dependent on groundwater levels; this has historically been conducted in the ~January- March timeframe. However, recent indications are that low groundwater may occur sooner, so it is possible that the first groundwater level measurement should be taken in ~mid-November.

Two water level measurement events shall be taken in advance to determine the optimal sampling event timeframe as noted below. Work shall be conducted similar to events conducted in the past (latest Final Report and Work Plan will be provided as GFI).

Because this event may occur post snowfall, snow machines or four-wheel drive vehicles will be required to access wells at the site. It is assumed that two snow machines will be required per day during the monitoring event. The Contractor should assume no delays will occur due to inclement weather. [

Phase 1 Planning: The Contractor will prepare a Draft Work Plan (WP) for each winter/low groundwater sampling event. The WP will document procedures to be utilized as part of the groundwater sampling activities to be performed in accordance with historical procedures, ADEC regulations and guidance, and the Decision Document.

The Contractor shall provide the draft WP to the COR (assume 10 days for DLA approval). Upon revision of DLA comments and approval, DLA will forward the DLA-approved Draft documents to ADEC for their review and comments, and allow for a thirty-day review period. The Contractor will finalize the report within 30 days after receipt of review comments and approval by the COR and ADEC, and submit one (1) electronic copy and two (2) CD-R media copies of the Final for ADEC to the COR. All copies shall be submitted to DLA; DLA will forward any deliverables to ADEC.

The Contractor shall provide a tentative schedule of deliverables and field actions in the task order proposal and submit a final schedule within ten days of task order award.

Phase 2: Sampling Event/Analyticals Submission: Following approval of the WP by ADEC, the Contractor will mobilize to the Site twice to collect groundwater elevation data to verify the optimal timing for the sampling event.

It is anticipated that the low groundwater sampling event will be conducted in the ~January-March timeframe.

Once the optimal groundwater level has been recorded in line with past low groundwater monitoring events, the following approach will be utilized by the Contractor to execute the sampling event:

• The Contractor shall mobilize to clear trail, since area is undeveloped, and access to monitoring wells may require snow clearing;

• The Contractor will utilize GPS surveying to locate up to 10 monitoring wells that cannot be located by conventional techniques due to excessive snow cover.;

• The Contractor will gauge up to 32 wells for free product and depth to water measurements (DTW) utilizing a groundwater interface probe; and

• Up to 32 monitoring wells will be sampled by the Contractor, utilizing various techniques as appropriate and set forth in the approved Work Plan and historically completed to assist in providing more reproducible data. When possible, use an inflatable packer deployed in a monitoring well to segregate portions of the screened interval and/or limit the rate of vertical flow.

Methods to be utilized to facilitate sample collection is presented below:

• Up to 17 monitoring wells will be sampled utilizing low-flow sampling methodologies;

• Up to 9 monitoring wells will be sampled utilizing low-flow sampling methodologies with an inflatable packer; and

• Up to 6 monitoring wells will be sampled using HydraSleeve samplers.

Quality assurances/quality control (QA/QC) samples will be collected and analyzed in accordance with the ADEC Field Sampling Guidance and as set forth in the approved WP. Standard samples, to include QC samples that shall be collected during each event for laboratory analyses as specified in the approved groundwater monitoring WP.

The Contractor will handle purge water generated during sampling activities on-site utilizing a granular activated carbon (GAC). The Contractor will be responsible for final disposal of any IDW generated during the monitoring event.

The groundwater samples will be submitted by the Contractor to an appropriately approved lab for the following parameters IAW historical groundwater monitoring events:

• Diesel Range Organics (DRO) via AK102;

• Residual Range Organics (RRO) via AK103;

• Gasoline Range Organics (GRO) via AK101;

• Lead via Method 6020;

• Volatile Organic Compounds (VOCs) via Method 8260B; and

• Polynuclear Aromatic Hydrocarbons (PAH) via Method 8270-SIM.

Following receipt of the analytical data from the Lab, the data will be validated by the Contractor’s chemist. Chain-of-Custody documentation will be submitted with the Contractor’s invoice.

Phase 3: Reporting:

Within 30 days following receipt of analytical data, the Contractor will submit an electronic draft of the Monitoring Report to the COR for review. The report will document the groundwater sampling event IAW ADEC regulations and guidance and historical site Reports. The Contractor shall provide the draft Report to the COR (assume 10 days for DLA approval). Upon revision of DLA comments and approval, DLA will forward the DLA-approved Draft documents to ADEC for their review and comments, and allow for a thirty-day review period. The Contractor will finalize the Report within 30 days after receipt of review comments and approval by the COR and ADEC, and submit one (1) electronic copy and two (2) CD-R media copies of the Final for ADEC to the COR. All copies shall be submitted to DLA; DLA will forward any deliverables to ADEC.

3.12 Task 12 – Operations & Maintenance (O&M)/Electricity Whittier Remedial System

There is no active remediation on the former Army/future City of Whittier property. A Bioventing system has been installed to address contamination that has migrated downhill onto the State-owned Alaska Railroad Property.

System installation was completed in 2018 and it ran for six-weeks in 2019 from mid-February through the end of March. The system was installed for optimum operation during periods of low groundwater (which historically have occurred from ~January-March).

The system, which began running mid-February 2019, has yet to be operated during optimal low groundwater period. To ensure proper operation of the system, the groundwater levels will be measured in ~mid-November to determine the low groundwater period prior to winter. Precipitation may factor into the groundwater levels, so significant local rainfall/snowfall events should also be tracked by the Contractor. Based on historical groundwater level measurements, it is likely that this system will only run for approximately three months, during the winter, per year.

A final Remedial Action Work Plan and an Operations and Maintenance (O&M) Manual are the primary documents for use in determining system O&M requirements (GFI). In addition, tech memos documenting activities during system operations will be provided as GFI.

The Contractor shall be responsible for system operation effective NLT 1 Sep 2020. Final reports from the 2020 operation will be turned over to the Contractor immediately upon contract award.

The Contractor shall be responsible for understanding the existing conditions at the site. It is critical that the existing remediation systems be kept fully operational, that mandated monitoring programs be maintained, and that the Contractor is familiar with site conditions and operations in order to effectively represent the Government in meetings with Regulators, the public, or other Government agencies. The Contractor shall perform operation and maintenance of the existing remedial system at the site in accordance with the site’s Remedial System Operation and Maintenance Manual.

Electricity (See Phase 6 below) to run the system is the Contractor’s responsibility. The Contractor must establish an electric account with the utility provider within ten (10) business days of award of this task. The Incumbent Contractor will have already closed and completed their billing responsibilities. The incoming Contractor shall assume responsibilities for electrical payment when low groundwater levels indicate that system operation will be feasible. The Contractor shall coordinate with electrical provider to restart electricity and coordinate billing.

The Contractor will take two groundwater level measurements (in ~ November and December) to ensure low groundwater is captured to assure the system can be turned on and operated for as long as seasonally possible.

Phase 1: Planning: The Contractor should review available documentation and propose a schedule as part of the proposal for the task order that will ensure weekly system O&M during system operation. The Contractor may propose any changes to the current O&M that will maintain efficiency and continuity.

Phase 2: Groundwater Elevation Monitoring/Seasonal System Startup: Following approval of the WP by the COR/ADEC, the Contractor will mobilize to the Site twice, the first time in approximately mid-November, to collect groundwater elevation data from MW30 to verify the optimal timing for the seasonal system start up. It is anticipated that the low groundwater will occur sometime between mid-Nov and last until March timeframe. If water level indicates that groundwater elevations are approximately 10 feet below mean sea level, or lower, at MW- 30, the Contractor shall notify the COR, ensure electricity is hooked back up, and begin seasonal operation IAW system O&M Manual. Appropriate system-startup measurements and readings shall also be taken at time of startup IAW the O&M Manual.

Phase 3: Weekly O&M: During each O&M visit, the Contractor will inspect and maintain the remedial equipment to ensure it is operating properly and as planned. Measurements and readings will also be collected by the Contractor to aid in continuous system operation and optimization. The O&M checklist to be completed during each site visit is included as Appendix E in the O&M Report.

O&M checklists and chain-of-custody forms will be included by the Contractor as backup documentation included with the monthly invoices.

The Contractor shall maintain written and/or electronic records of all data collected as part of the remedial system O&M, site monitoring efforts, and data that should be included in Phase 4 as appropriate (to be included in DLA submittals).

The Contractor is required to notify the COR if control of the plume appears to be trending toward leaving the site, growing, or moving in a direction currently not known or anticipated.

Phase 4: Monthly Tech Memo: At the conclusion of each month of operation, the Contractor will prepare a Technical Activity Summary, 1 page or less, documenting activities conducted during that period. Summary document should include site observations, the checklists as attachments, vapor effluent sample results and lab data as attachments, and any recommendations for routine changes of operations. This will be an electronic document and submitted to the DLA COR by the 20th day after the month the summary documents. If analysis has not been received by that time, the Contractor shall advise the COR of the delay and when results can reasonably be expected.

Phase 5: Annual Report: At the conclusion of the seasonal system operation and O&M at this site, the Contractor shall compile an annual report for the Whittier Remedial System using the monthly tech memo data from Phase 4.

Report shall include the data presented in graph form, depict any trends, and propose significant changes or enhancements for system operation. The annual report will include measured groundwater elevations, system run time, observed in-situ respiration rates, and the estimated volume of biodegraded fuel. The Contractor shall provide a draft and final Annual Report and allow for a thirty-day review period by ADEC of the Draft after DLA approval of the Draft (assume 10 business days for DLA approval). A one hour long telephonic/local meeting including the Contractor, ADEC, and DLA is anticipated as part of the Report approval process. DLA will forward approved Draft documents to ADEC for their review and comments. The Contractor will finalize the report within 30 days after receipt of review comments and approval by the COR and submit one (1) electronic copy and one (1) CD-R media copy for ADEC and to the COR. All copies shall be submitted to DLA; DLA will forward all deliverables to ADEC.

Phase 6: Electrical Payments: Once it is determined that groundwater levels are rising, the Contractor will recommend seasonal shut down of the system. The Contractor will contact the electrical provider for shut down, and request final billing. Copies of the CEA invoice must be uploaded into WAWF for payment. Historical data is available for review.

3.13 Task 13 – Alaska Railroad Annual Fee for Site Access at Whittier, AK

For access to and use of their lands to expedite cleanup from the Former DFSP Whittier fuel releases, the Government must access and utilize lands owned by the State-owned Alaska Railroad Corporation (ARRC).

The Government has entered into an Entry Permit and 2017 Supplement to that Entry Permit with the ARRC which requires that the Government must pay an annual fee for this access and use. In addition, the Contractor must ensure they hold additional insurance to meet their requirements (addressed specifically as a requirement under the above task for Whittier Summer/High Groundwater Monitoring).

The Contractor will receive an annual access fee, make payment directly to the ARRC and advise the Government when payment is made. Invoicing for the task order can be submitted once payment is made to AKRC and will include a copy of the payment method (copy of check, receipt, or other electronic transfer).

3.14 Task 14 – Decision Document Addendum: Former DFSP Whittier

Due to changes in 18 AAC 75 in 2017, which included changes to required cleanup levels and added new potential chemicals of concern with new cleanup levels, historical reviews of past data were conducted in 2018 to determine if the new regulations would change the cleanup strategy and remedial action at this site. This research was conducted under the previous contract and resulted in a letter report.

The research determined that no changes were required; however, documentation of the review and memorializing the findings will need to be completed. The Government requires an Addendum to the Decision Document to formally record the research and determination. ADEC is still determining the format for this documentation.

The Contractor shall write this document in a Technical Memorandum format with an approximate length of 12 pages or less, plus 4 pages of figures. The Decision Document and Historical Research Document are available electronically and must be compiled into a format that will be approved and signed by DLA and State.

The Contractor shall provide a draft and final document and allow for a thirty-day review period by ADEC of the Draft after DLA approval of the Draft (assume 10 business days for DLA approval). A one hour long telephonic/local meeting including the Contractor, State and DLA is anticipated as part of the Report approval process. DLA will forward approved Draft documents to State for their review and comments. The Contractor will finalize the report within 30 days after receipt of review comments and approval by the COR and submit one pdf copy for signature to the COR. Once the COR has secured DLA and State signatures and provided to the Contractor, within 10 days the Contractor will finalize the document incorporating the signature pages, and provide

(1) electronic copy and two (2) CD-R media copy for State to the COR. The Contractor shall also provide the document in an editable format (word, etc.) to the COR, as well as the original signature pages, to the COR. All copies shall be submitted to DLA; DLA will forward all deliverables to State.

3.15 Task 15 –Former DFSP Whittier Well Maintenance and Assessment

Based on recommendations from previous reports and discussions with ADEC, well maintenance and assessment work is required at the Former DFSP Whittier site. Known work to be conducted includes decommissioning of three wells, replacement of three wells, well monument repair at five wells, well inspection of 30 wells, and groundwater contaminants of concern trend analysis. Additional work includes well obstruction clearing at five wells, installation of snow poles at 30 wells, and well surveying at 30 wells.

Other work required within this task includes well inspection, surveying, and completing a Mann-Kendall trend analysis conducted using both existing and historical monitoring data.

All field work shall be conducted by the Contractor with one mobilization. See Phase 2 for specifics on field work requirements. Work will be done prior to snow fall and will not require site or snow clearing for the work to be accomplished.

Phase 1: Planning for Well Maintenance and Assessment: The Contractor will prepare a Draft and Final Well Maintenance and Assessment Work Plan (WP), including a proposed schedule for the work to be completed. The WP will document procedures to be utilized as part of the groundwater sampling activities to be performed in accordance with historical procedures, ADEC and guidance, and the Decision Document. The Contractor shall provide the draft WP to the COR (assume 10 days for DLA approval). Upon revision of DLA comments and approval, DLA will forward the DLA-approved Draft documents to ADEC for their review and comments, and allow for a thirty-day review period. The Contractor will finalize the report within 30 days after receipt of review comments and approval by the COR and ADEC, and submit one (1) electronic copy and two (2) CD-R media copy of the Final for ADEC to the COR. All copies shall be submitted to DLA; DLA will forward any deliverables to

ADEC.

The Contractor shall provide a tentative schedule of deliverables and field actions in the proposal and submit a final schedule within ten (10) business days of task award.

Phase 2: Field Work for Well Maintenance and Assessment:

• The Contractor shall clear obstructions from five groundwater monitoring wells. These wells include MW54R, MW88R, MW95 and MW54. The fifth well is included to address an additional well that may be discovered during ongoing monitoring events. Obstructions should be cleared using the best available technology and process to minimize any potential damage to the well.

• The Contractor shall install 30, 10-foot orange polyvinyl chloride (PVC) snow poles at 30 groundwater monitoring wells (one per well, affixed to the monument).

• The Contractor shall conduct well surveying, including top of casing (TOC) elevations, at 30 groundwater monitoring wells. Wells will be surveyed by an Alaska Licensed Professional Land Surveyor. Horizontal distances will have an accuracy of 0.10-feet. Vertical elevations of top of well casing will be surveyed to the nearest National Geodetic Datum with an accuracy of 0.01-feet.

• The Contractor shall decommission of 3-2” monitoring wells, at estimated depths of 35’ each. Wells include MW85, MW87, and the three wells that will be replaced to include MW87R. Assume an average depth of 65’ and 2” wells for the two unnamed wells. Decommissioning should include removal of any above ground surface protective structures. This includes standpipes and protective bollards. All well decommissioning should be in accordance with the guidance contained in the Alaska Department of Environmental Conservation’s Monitoring Well Guidance (2013). The Contractor will place native soil from approximately 1 foot below ground surface to surface level grade. Upon completion of decommissioning activities, the location of the former well will be graded flat to match with the native surrounding ground surface.

The Contractor shall replace/install 3-2” monitoring wells, at an estimated depth of 65’ each. One specific well to be replaced in MW87R. The other two yet unidentified wells should be assumed to be 2” wells at an approximate depth of 65’ each. Well installations should be in accordance with the guidance contained in ADEC’s Monitoring Well Guidance (2013).

• The Contractor shall repair 5 well monuments and placing monuments for the 3 new wells, to include MW69 and MW93 and one unidentified well, in addition to the 3 new wells required above. The wells will have their surface monuments either repaired or fully replaced. The well monuments include a steel, 5-inch diameter stovepipe equipped, and secured with locking cap. Existing damaged well monuments will be removed using an excavator or drill rig.

Soil and Investigation Derived Waste (IDW) Handling for all Site Activities: IDW water will be transferred by the Contractor to 55-gallon drums and transported to the central staging area designated by the COR. If lacking a petroleum sheen, development water will be filtered by the Contractor through the GAC system and discharged to the ground surface, at least 100 feet from any surface water body or drinking water well. If a petroleum hydrocarbon sheen is present, the Contractor will use sorbent material to remove the sheen prior to GAC treatment.

The Contractor will place soil cuttings generated during borehole installation in 55-gallon drums and transported to a central staging area designated by the COR pending off-site transportation and disposal by the Contractor.

The Contractor will place disposable PPE and sorbent pads in a garbage bag and dispose them in a public solid waste receptacle in Whittier, Alaska.

Following completion of well installation activities, the Contractor will sample the soils for applicable waste profiling and characterization parameters. Upon receipt of the analytical results, within two business days, a completed waste transport request form will be submitted to the State for review and approval prior to transport to an approved facility for treatment and/or disposal based on analytical results. Documentation for the transportation and disposal of any petroleum-impacted soil generated during system installation will be submitted as an appendix to the Well Maintenance and Assessment Report.

Phase 3: Well Inspections: The Whittier monitoring program historically has a requirement to inspect 30 wells.

The Contractor will inspect the wells to determine each well’s status, data relevance, and to determine whether to continue or cease monitoring each well. The Contractor shall gather the inspection data and incorporate the findings and any recommendations into the Well Maintenance and Assessment Report.

Phase 4: Mann-Kendall Statistical Trend Analysis: Monitoring at the Whittier site has been on-going for over a decade. An updated, standard “Mann-Kendall Trend Analysis” is necessitated using data from 2012-2019 to determine if there are any new trends and recommendations. The Mann-Kendall Trend Analysis process is a standard statistical analysis using Excel and existing data to identify trends in the existing data. The Contractor shall gather the analysis data and incorporate the analysis into the Task Report.

Phase 5: Reporting: Within 30 days following receipt of analytical data and completion of field work, the Contractor will submit an electronic draft of the Monitoring Report to the COR for review. The report will document the groundwater sampling event IAW ADEC regulations and guidance and historical site Reports. The Contractor shall provide the draft Report to the COR (assume 10 days for DLA approval). Upon revision of DLA comments and approval, DLA will forward the DLA-approved Draft documents to ADEC for their review and comments, and allow for a thirty-day review period. The Contractor will finalize the Report within 30 days after receipt of review comments and approval by the COR and ADEC, and submit one (1) electronic copy and two (2) CD-R media copies of the Final for ADEC to the COR. All copies shall be submitted to DLA; DLA will forward any deliverables to

ADEC.

3.16 Task 16 –Five Year Review (5YR), Former DFSP Whittier

ADEC regulations (18 AAC 75) generally parallel the CERCLA process for cleanup of contaminated sites. As such, ADEC requires “periodic” reviews of site remedies to ensure they are functioning as intended and remain protective of human health and the environment. For more complex sites or those with more public interest, this periodic review is a formal process and done quinquennially. In addition, the 5YR identifies issues found during the review, if any, and identifies recommendations to address them. This review takes into account any regulatory changes since the Decision Document, current and future land use changes, and any applicable technological advances. The 5YR due date is 5 years from the signature of the site Decision Document. For Whittier, the Decision Document was signed on 21 April 2016, making the First Five-Year Review due by 21 April 2021. The Contractor will provide a proposed schedule for the documents required under this task order within 10 days of task award. This schedule will be discussed with the State and approved by the COR prior to project initiation.

The Contractor will conduct a 5YR generally in accordance with EPA’s document, Comprehensive Five-Year Review Guidance, June 2001, EPA540-R-01-007. This should be considered a low complexity site due to fewer requirements since EPA is not engaged on this site.
