NFD02 SLURRY PIT/SLUDGE TRENCH TANK 21

1.1 Environmental History:

NFD Site 2 is located southeast of Facility 6 inside the dike area surrounding Tank #21. In

September and October 1954, a slurry pit and sludge trench were excavated. All bottom sludge, rust and wash water generated by tank cleaning was pumped into them. Approximately six barrels of tetraethyl lead contaminated rust and sludge from an aviation gasoline tank were deposited in these areas. The slurry pit was approximately 10 feet wide by 10 feet long. The sludge trench was approximately 3 feet wide by 20 feet long.

The Site Assessment Work Plan was based on the findings from the November 11, 2014, report titled Summary of Phase II Assessment Findings. The final work plan was submitted on August

21, 2015 and recommended the following:

• Installation of up to 16 soil borings to 1 ft. into groundwater, at approximately 6 ft. bgs, and collect up to 6 soil samples.

• Installation of three 1-inch in diameter monitoring wells up to 12 feet in depth with samples analyzed for VOCs, PAHs, TRPH and select metals (As, Cd, Cr, Pb)

Florida DEP approved the Work Plan in a letter dated October 23, 2015. Fieldwork began on

November 16, 2015 and was completed in June 2016.

A horizontal well (Vertebrae well) with 10 screened intervals was installed on November 14, 2016. On December 5, 2016, one sample was collected from 10 screened intervals and analyzed for BTEX, MTBE and Naphthalene by EPA Method 8260, PAHs by EPA Method 8310, and

TRPH by EPA Method 8440. Based on the December 2016 groundwater results, only xylene (22 micrograms per liter - well VW-8) was above the GCTLs. Quarterly sampling was completed by collecting ten samples from the vertebrae well, one at each screened interval, and from 5 vertical monitoring wells. Groundwater samples were analyzed for BTEX, PAHs and TRPH for each quarterly monitoring event.

In July 2017 the second groundwater monitoring event at NFD Site #2 was conducted. Ten vertebrae well points and five micro-wells (MW-1, MW-2, MW-3, MW-4, and MW-5) were sampled for benzene, toluene, ethylbenzene, and xylenes (BTEX), and methyl tert-butyl ether

(MTBE) using United States Environmental Protection Agency (USEPA) Method 8260B, Polycyclic Aromatic Hydrocarbons (PAHs), using USEPA Method 8270 and Total Recoverable

Petroleum Hydrocarbons (TRPH) using the FLPRO Method. Average depth to water was measured at 2.73 below top of casing (btoc).

The laboratory analytical results of the July 2017 groundwater event only detected benzo(a)pyrene (0.14 (μg/L)), dibenz(a,h)anthracene (0.35 (μg/L)) and indeno(1,2,3-cd)pyrene

(0.17 (μg/L)) above GCTLs in well VW-7. Based on the findings, it was recommended that additional groundwater monitoring to adequately characterize groundwater conditions.

No petroleum contaminants were detected above GCTLs during the fourth Post Active

Remediation Monitoring (PARM) event in October 2017 or the fifth PARM event in February

2018. The report for the fifth PARM event, dated March 2, 2018, concludes that requirements for NFA with conditions have been met. Report recommending conditional closure was submitted to the regulators. A No Further Action (NFA) approval is dependent on the results of site NFD02A.

For FLC Jacksonville NFD02 SLURRY PIT/SLUDGE TRENCH TANK 21, the following actions are required to be completed by contractor upon receipt of a task order (see PWS Section

2.2.1):

NFD02A ST 21

In November 2003 a Limited Asbestos Survey was performed for the AFFF pipeline located between 3rd and 5th Streets at the facility and an Underground Fuel Piping Investigation was conducted in November of 2004. The report summarized field activities in response to discovery of a fuel leak. An Asbestos-Containing Material (ACM) Survey was prepared and submitted to

FDEP in November of 2004 stating that the asphaltic-wrapped piping contained approximately

45 percent chrysotile, resulting in removal of 610 feet of asphaltic-wrapped piping. Also, 900 feet of underground fuel piping was removed. Following pipe removal, soil samples were collected at 100-foot intervals along the piping removal areas. Temporary micro-wells were installed at the soil sample locations with the highest TRPH concentrations, and groundwater samples were collected. Resulting soil and groundwater analysis indicated that soil TRPH concentrations exceeded soil cleanup target levels (SCTL) for leachability. Only benzene exceeded the Groundwater Cleanup Target Levels (GCTL).

A January 2019 Site Assessment Report evaluated soil analyses from a September 2018 soil/groundwater sampling event and identified benzo(a)pyrene concentrations exceeding the

SCTL criteria in soil borings SB-4. The report also found that the extent of soil contamination above SCTLs had been adequately delineated. The groundwater analytical indicated petroleum-related constituents of concern were below GCTLs in groundwater. based on the soil and groundwater results, NFA with conditions was recommended for the site.

August 2019 – The January 2019 Site Assessment Report was revised and indicated B(a)P concentrations exceeding the residential SCTL criteria in soil boring SB-4. The report recommended additional soil sampling to delineate the soil around SB-4. The groundwater analytical results were unchanged. Based on the soil analytical results, the report recommended collecting additional soil samples at SB-4 and developing a Limited Scope Remedial Action

Plan for a small source removal for NFD Site #2A.

A limited scope remedial action plan recommended source removal of all accessible contaminated soil to approximately 5 feet below land surface to reach residential soil cleanup target levels as set forth in Chapter 62-777 of the Florida Administrative Code (FAC) (Table 1).

Source removal will be completed prior to contract award. It is anticipated that semi-annual groundwater sampling will be required prior to site closure.

For FLC Jacksonville NFD02A ST 21, the following actions are required to be completed by contractor upon receipt of a task order (see PWS Section 2.2.1):

3.1.1 Semi-Annual Groundwater Sampling – [PPW Reference Item 005]

Meetings include one kickoff meeting, one review meeting, and one regulatory review meeting

NFD03 SLURRY PIT TANK 20

NFD Site 3 is located northeast of Facility 5 inside the dike area surrounding Tank #20. In

September and October 1954, a slurry pit was excavated, and all bottom sludge, rust and wash water generated by tank cleaning was pumped into it. Approximately eight barrels of tetraethyl lead contaminated rust and sludge from an aviation gasoline tank were deposited in these areas.

The slurry pit was approximately 10 feet wide by 10 feet long.

The current Site Assessment Work Plan is based on the findings of a Final Work plan implemented in August 21, 2015 which included:

• Install up to 16 soil borings into the water table, at approximately 6 ft. bgs, and collect up to 6 soil samples.

• Install 3 - 1" Monitoring Wells up to 12 feet in depth.

• Collect groundwater samples from each well to be analyzed for VOCs, PAH TRPH and select metals (As, Cd, Cr, Pb)

Fieldwork occurred from November 16, 2015 to March 2016. The LSRAP was completed, reviewed and accepted. Source removal of 3,151 cubic yards of soil was completed in late 2016 and approximately 507 cubic yards of contaminated soil were removed in 2017. Quarterly

PARM sampling of five (5) wells began in early 2017 and was anticipated to continue through

May 2018.

In January 2017, the First Quarter Post Active Remediation Monitoring event (PARM) for NFD

#3 as conducted. Groundwater samples were collected from five monitoring wells (03-MW-01, 03-MW-2R, 03- MW-11R, 03-MW-12, DFM-T-13) for analysis. Analytical results were below

GCTLs in all groundwater samples.

In April 2017, the Second Quarter PARM event was conducted. Groundwater samples were collected from the aforementioned monitoring wells for analysis. Analytical results were below

GCTLs in all the groundwater samples collected except 03-MW-2R, where Benzene was detected at a concentration of of 1 μg/L exceeding the GCTL. However, benzene was not detected above the GCTL in the duplicate sample for 03-MW-2R. Continued groundwater monitoring was recommended for three more quarters for NFD Site #3.

In July 2017, the Third Quarter PARM event on site was conducted. Five groundwater samples were collected for analysis and depth-to-water (DTW) was measured at depths ranging from

0.49 (03-MW-2R) to 1.79 (03-MW-01) feet below land surface (bgs) with an average DTW of

1.18 feet bgs. Benzene was detected in monitoring wells 03-MW-2R (6.1 μg/L) and 03-MW-12

(1.5 μg/L) at concentrations exceeding the GCTL of 1 μg/L. Based on the exceedances, Continued groundwater monitoring was recommended for NFD Site #3.

In September, 2017, FDEP reviewed and accepted the Second and Third Quarter Post Active

Remediation Monitoring Reports for NFD Site #3. FDEP also recommending sampling monitoring wells MW-5 and MW-6 in the next sampling event. The report recommending conditional closure was submitted to the regulators.

August 2019 – The 4th quarter Post-Active Remediation Monitoring Report indicated analyte concentrations were below GCTLs except 03-MW-1, 03-MW-2RR and 03-MW-12. Based on discussions at the January 2019 partnering meeting, it was decided that additional groundwater assessment would be conducted at NFD Site #3 followed by groundwater treatment to remove any residual groundwater contamination at the site. The report also recommended six soil samples be collected around the truck stand, road and northwest, southwest and southeast corners of the excavation to determine if soils remain above industrial SCTLs.

A Groundwater Assessment Work Plan was completed and submitted. It is anticipated that semi-annual groundwater sampling will be required prior to site closure.

For FLC Jacksonville NFD03 SLURRY PIT TANK 20, the following actions are required to be completed by contractor upon receipt of a task order (see PWS Section 2.2.1):

NFD08 “A” ROAD & 2ND STREET

In May 1993, free product and soil contamination were discovered in an area south of Loading

Rack 53, referred to as Area A, on the FLC Jacksonville facility. In 1997, a remediation system was installed and operated until groundwater contamination was reduced below the natural attenuation default concentrations.

In 2000, a Natural Attenuation Monitoring (NAM) plan was approved, and groundwater monitoring at the site continued through January 2003. Groundwater contamination at the time was below Natural Attenuation Default Concentrations (NADCs); however, contaminant levels exceeded the state established GCTLs at monitoring well locations. There was no evidence of free product at any of the wells sampled.

In May 2006, facility personnel discovered free product at recovery well (RW)-3. It was believed that the free product was likely residual fuel from the previously evaluated release rather than a new spill. Between May 2006 and November 2008, additional assessments and monitoring activities within the vicinity of RW-3 were conducted. The assessments identified an area approximately 25 feet (ft.) by 30 ft. containing residual free product.

In June 2009, and interim source removal was conducted near the intersection of A Road and

Second Street, and 350 tons of contaminated soil was excavated to a depth of approximately one to two feet beneath the groundwater table. Free product was observed during excavation activities and approximately 7,400 gallons of groundwater/free product was removed from the excavation area. A 300-gallon mixture of Catalina Biosolutions “biocritters” was applied to the excavation area prior to adding backfill to the area.

During partnering meetings with FDEP in May 2010, it was agreed that semi-annual monitoring was appropriate since the loading rack area was due for upgrades in the next few years. A proposed scope of work and monitoring plan was provided to FDEP for approval.

In January 2011 and January 2012, groundwater monitoring activities identified two well locations exhibiting TRPH concentrations exceeding GCTLs. Free product was not detected in any of the monitoring wells during both events. Groundwater monitoring was recommended to continue per the approved sampling plan submitted to FDEP in 2010.

In January 2012, groundwater sampling results at monitoring well ARMW-1 and NFD-53-13 exhibited groundwater concentrations greater than GCTLs. Free product was not detected in any of the monitoring wells sampled during the event. The results show a continued downward trend in benzene concentrations in ARMW-1. Based on the water level gauging, the groundwater flow direction was north-northwest and exhibited tidal influence effects. The groundwater flow direction was consistent with previous evaluations. Following a project review meeting in

January 2012 with FDEP/DLA/FLC, it was agreed that a single annual sampling event was appropriate for this site since loading rack area renovations were currently scheduled for 2018.

In January 2013, groundwater samples were collected from six monitoring wells (ARMW-1, ARMW-2, ARMW-3, NFD-53-6, NFD-53-8, and NFD-53-13) and submitted for analyses for

BTEX, MTBE, PAHs, and TRPH. TRPH and benzo(a)anthracene concentrations exceeded

GCTLs in well NFD-53-13. No other exceedances were identified. Free product was not detected in any of the monitoring wells during groundwater monitoring activities. The groundwater flow direction is generally consistent with previous groundwater flows encountered at the facility.

In 2015, a supplemental site assessment at NFD #8 “A” Road at 2nd Street, in support of the

Truck Rack #53 relocation project was completed. Activities included installation of 20 soil borings to 10’ bgs utilizing DPT methods, with one soil sample collected per boring and analyzed for VOCs, SVOCs and TRPH by FL-PRO. Annual groundwater monitoring included collection of samples from wells ARMW-1, ARMW-2, ARMW-3, NFD-53-6, NFD-53-8, and

NFD-53-13. Site assessment results were documented in a report submitted to FDEP in June

2016 and recommended the development of a Limited Scope Remedial Action Plan (LSRAP) to conduct a shallow source removal at the site; the site assessment report was approved by FDEP in August 2016.

In February 2017, a LSRAP was submitted to FDEP for review and was approved in April 2017.

The LSRAP approach includes the removal of soils containing benzene and TRPH above default industrial SCTLs, application of Oxygen Release Compound (ORC) into the bottom of the excavation, and dewatering. The LSRAP also included installation of four 12-feet deep monitoring wells for four post-active remediation monitoring (PARM) events on nine monitoring wells. The LSRAP soil removal field activities were completed and the first PARM event analytical results from October 2017, indicated Naphthalene exceedances of GCTLs in two monitoring wells of and TRPH at 5100 μg/L) GCTLs. The three remaining PARM events were scheduled for December 2017, March 2018, and July 2018.

August 2019 – Laboratory analytical results from the September 2018 PARM sampling event reported petroleum-related constituents of concern at concentrations above their respective groundwater cleanup target levels (GCTLs) in in micro-wells: 8-MW-1: benzene (4.3 μg/L); 8-

MW-2: benzene (9.4 μg/L), ethylbenzene (36 μg/L), total xylenes (28 μg/L), TRPH (6,800 μg/L) and naphthalene (23 μg/L). Analytes in micro-wells 8-MW-3, 8-MW-4 and NFD-53-8 were below FDEP GCTLs. Concentrations of benzene decreased, and toluene was no longer present in the groundwater sample collected from monitoring well 8-MW-1. Concentrations of benzene and ethylbenzene increased, and total xylenes remained consistent in the groundwater sample collected from monitoring well 8-MW-2 since the sampling event conducted in May 2018.

The site is undergoing a pilot test using one horizontal test well to ass Soil Vapor Extraction

(SVE-1) and Air Sparging will be assessed using one vertebrae test well (AS-1, AS-2, and AS-

3). Existing monitoring wells 8-MW-1, 8-MW-2, 8-MW-4, will be monitored to assess the influence of both technologies. MP-1 and MP-2 will be installed prior to the test to be used during the SVE pilot test and 8-MW-5, 8-MW-6, and 8-MW-7 will be installed prior to the test and be used during the Air Sparging pilot test. It is anticipated the site will be required to undergo semi-annual groundwater sampling and will possibly require air-sparging in the future.

For FLC Jacksonville NFD08 “A” ROAD & 2ND STREET, the following actions are required to be completed by contractor upon receipt of a task order (see PWS Section 2.2.1):

3.1.1 Semi-Annual Groundwater Sampling – [PPW Reference Item 011]

NFD09 DITCH/PETROLEUM CONTAINING WASTE TANK SITE

ALONG 4TH STREET

SECTION 1.0 BACKGROUND

In July 2008, a petroleum release to the stormwater system near the petroleum-containing waste

(PCW) tank occurred. The cause of the discharge was unknown, but it was believed that petroleum contact water had discharged into the drainage culvert through the stormwater inlet grate near the north side of the PCW tank, which then flowed through underground piping into the ditch. In response to the release, a vacuum truck was utilized to remove petroleum-impacted soil in the drainage ditch. Approximately 6-inches of impacted soils were removed during this action. Impacted material along the ditch was excavated to remove contamination from the site and to mitigate potential impact to stormwater.

PermeOx® and Biosolve® were applied throughout the excavated area and were concentrated in locations where a higher probability for residual petroleum hydrocarbons existed, such as the underground utilities encountered in the southern portion of the excavation and the sidewall beneath the tank pad. PermeOx® Plus and Biosolve® are registered with the FDEP Innovative

Product Program for use on petroleum hydrocarbon bioremediation. Application of these products to an open excavation does not constitute injection as defined in Chapter 62-528, Florida Administrative Code (F.A.C.), so a FDEP Underground Injection Control permit was not required for application of these products. Approximately 150 pounds of PermeOx@ Plus was applied in the solid form on the floor of the excavation and again in the middle of the smear zone

(approximately 4 feet below land surface [ft bgs]) of the excavation.

The Source Removal Report dated January 2012 recommended quarterly post-biotreatment groundwater monitoring for hydrogen-ion concentration (pH), dissolved oxygen (DO), and total dissolved solids (TDS) and installation of a downgradient well be installed near the southern end of the ditch. Total recoverable petroleum hydrocarbons (TRPH) by FDEP Method FL-PRO and

Anionic Surfactants by Standard Method (SM) 5540C were added to the analytical parameter list. Post-biotreatment groundwater monitoring began in October 2012 per FDEP's April 2012 response to the Source Removal Report.

Post Active Remedial Monitoring (PARM) activities related to the source removal began in

October 2012. Two more sampling events were conducted in January of 2013 and January of

2015, referred to as Quarterly Event #2 and Quarterly Event #3 in the PARM reports submitted o

FDEP. Laboratory results from Quarterly Event #2 exceeded the GCTLs for TDS in MW-1

(677μg/L) and MW-2(4,830 μg/L). Parameter concentrations from Quarterly Event #3 did not exceed GCTLs.

Quarterly Event #4 groundwater sampling was conducted in May 2015 as described in the July

2015 Quarterly Event #4 PARM Report submitted to FDEP in July 2015. TRPH and TDS, were not detected at concentrations above GCTLs in the groundwater samples. NFA was recommended for the site NFD #9.

In October 2016, the 1st Quarter Groundwater Monitoring Report was submitted per FDEP request. FDEP required two quarters of groundwater monitoring be conducted (including

BTEX+M and PAHs) before the site could be considered for closure.

In January 2017, the 2nd Quarter Groundwater Monitoring Report was submitted. The groundwater laboratory analytical results for the August 2016 groundwater monitoring event did not exceed FDEP GCTLs for BTEX+M and PAHs in any of the monitoring wells.

In March 2017, the Florida Department of Environmental Protection accepted the conclusion that the site groundwater meets the no further action conditions in Chapter 62-780. However, based on discussions at the February 2017 Partnering Team meeting, an additional soil investigation was needed at the site before Site 9 can achieve NFA.

In July and September 2017, a Supplemental Site Assessment was conducted to address data gaps identified in the 2012 Source Removal Report. Soil sampling results identified and delineated contamination above residential, leachability, and/or industrial SCTLs around two previous soil boring locations. The Supplemental Site Assessment Report recommended limited source removal to below residential SCTLs, followed by one quarter of PARM.

Soil in Areas A and B exhibiting petroleum exceedances of residential SCTLs and ASCTLs have been excavated and disposed offsite at the Chesser Island, Subtitle D landfill in Folkston, Georgia as proposed in the August 2018 LSRAP. Groundwater laboratory analytical results from the September 2019 sampling event were below GCTLs in the groundwater samples collected.

Prior to closure recommendations, additional soil assessment activities are required be completed at Area C.

NFD11 DEX-1 CENTRAL DFM

SECTION 1.0 BACKGROUND

In November 2006, fuel piping excavation and closure occurred at the site. Soil borings were installed along the pipeline runs and adjacent to piping structures and screened using a flame ionization detector (FID). The sample collected from soil boring HA-7 location within the DEX-

1 area exhibited elevated organic vapor concentrations. A soil sample from this location was submitted to the laboratory for analysis. All target parameters were below Soil Cleanup Target

Levels (SCTLs) with the exception of benzo(a)pyrene (BaP) and TRPH.

In April 2007, soil boring HA-7 was converted to a temporary monitoring well and sampled. All analyzed parameters were below GCTLs with the exception of benzo(a)anthracene and indeno(1,2,3-cd) pyrene. In November 2008, three soil borings (HA-7R, HA-11 and HA-12) were installed to verify the presence of PAH and/or TRPH constituents in soil and groundwater.

Analytical results showed BAP soil exceedances in all three locations. A groundwater sample was collected from temporary monitor well TMW-2 and analyzed for PAHs. PAHs were not detected in the groundwater sample. Based on the data, additional soil assessment was recommended to define and quantify the extent of BaP and BaP equivalents.

In Aug 2009, the FDEP required that additional soil assessment activities and groundwater monitoring be conducted in the source area and a downgradient well for at least 4 quarters with the last two events showing concentrations below the respective GCTLs.

In April 2010, 13 soil borings (SB-1 through SB-13) were installed at locations surrounding the former HA- 7R, HA-11 and HA-12 borings. Vadose zone (approximately 3- ft bgs) samples were collected and field screened for total organic vapor concentration. Select soil samples were submitted for laboratory analysis of PAHs by EPA Method 8270C SIM. Based on the April

2010 assessment activities, the extent of the BaP and BaP equivalents were adequately defined to the south and southwest but not to the north or east. Further soil assessment prior to the installation of groundwater wells was recommended.

Additional soil and groundwater sampling occurred in December 2010 and January 2011,.

Seventeen soil borings (SB-14 through SB-30) and three monitoring wells (DEXMW-1 through

DEXMW-3) were installed. Soil sample analytical results showed BaP exceedances in SB-18 and SB-21 and groundwater analytical results showed no exceedances. The report recommended that groundwater monitoring continue for the site for at least four quarters.

In 2016, source removal occurred at the site to remove soil with concentrations exceeding

SCTLs identified during previous site investigations. After multiple source removal events, four quarterly Post Active Remediation Monitoring (PARM) events were conducted. The first PARM event was conducted in April 2016 and petroleum-related constituents of concern were detected above the GCTLs for TRPH in monitoring wells DEX-MW3 and 11-MW-01. The second

PARM event was conducted in July 2016 and petroleum-related constituents of concern were not detected above the GCTLs. The third PARM event was conducted in October 2016 and petroleum-related constituents of concern were detected above the GCTLs in monitoring well

11-MW-01. Prior to conducting the fourth PARM event, two groundwater extraction events from monitoring well 11-MW-01 were conducted due to elevated TRPH concentrations in two quarterly post active remediation monitoring events. A PVC stinger was attached to the top of monitoring well 11-MW-01 and connected to a 3,000-gallon capacity vacuum truck. The vacuum truck ran continuously for 8 hours during each event to maximize petroleum recovery.

The first extraction event (February 2017) removed 1,750 gallons of water. The second extraction event (March 2017) and removed 1,300 gallons of water. In April 2017, the fourth

PARM event was conducted. Petroleum-related constituents of concern detected were below

GCTLs in monitoring wells DEX-MW1, DEX-MW-2, DEX-MW3, 11-MW-01, and 11-MW-02.

The duplicate groundwater sample collected from monitoring well 11-MW-01 showed contaminant levels above GCTLs for naphthalene (39 μg/L), 1-methylnaphthalene (44 μg/L), and 2-methylnaphthalene (47 μg/L).

Based on the exceedances observed in the fourth event, continuation with PARM was recommended. FDEP concurred in September 2017. No free product or contaminants above

GCTLs were detected during the October 2017 PARM event. The most recent PARM event noted one well with slight detect of benzo(a) anthracene.

November 2018 – The Groundwater Extraction Report (Events 3 and 4) noted that during the

July 2017 groundwater sampling event, free product was observed in micro-well llMW-01 for the first time since the source removal. Two extraction events in September and October 2017 removed a total of 5,800 gallons of water from monitoring well ll-MW-01. The report recommended continued groundwater monitoring for NFD Site #11 - Central DFM Area: DEX-

1 to see if contaminant concentrations have decreased below GCTLs.

November 2019 - Groundwater analytes from the September 2019 sampling event were below

GCTLs in all groundwater samples. Five consecutive quarters of groundwater sampling were conducted which did not exceed GCTLs. The report recommended No Further Action without controls based on the criteria in Chapter 62-780.680, FAC.

The May 2020 groundwater sampling event has been found to continue below GCTLs in all groundwater samples collected. NFA has been requested and is under evaluation by FLDEP.

For FLC Jacksonville NFD11 DEX-1 CENTRAL DFM, the following actions are required to be

3.1.1 Well Abandonment – [PPW Reference Item 015]

Five (5) 2-inch wells schedule 40

Wells are installed in unconsolidated overburden

3.1.2 Site Closeout – [PPW Reference Item 016]

Meetings include one kickoff meeting, one review meeting, and one regulatory review meeting

NFD12 JP-5 WEST OF PS2

In June 1999, 50 gallons of diesel fuel were released west of Pump Station # 2 when fuel was pumped into an open-ended pipe. Approximately 25 cubic yards (CYs) of contaminated soil was removed and product was recovered from temporary wells.

In March 2003, 10 soil borings were installed, and soil was field-screened with an organic vapor analyzer (OVA) equipped with a flame-ionization detector (FID). Soil samples were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX), methyl tertiary butyl ether

(MTBE), naphthalenes, and other polynuclear aromatic hydrocarbons (PAHs). Contaminant concentrations exceeding Soil Cleanup Target Levels (SCTLs) were discovered in several samples and four groundwater monitoring wells were subsequently installed to assess groundwater conditions. Groundwater samples exhibited naphthalene concentrations above the

FDEP groundwater cleanup target levels (GCTLs).

In March 2005, subsurface application of Fenton Reagent commenced and continued with12 applications over a 24-month period. Several of the groundwater monitoring parameters continued to exceed the FDEP GCTLs, an alternative approach to remediation was submitted to and approved by the FDEP. In July 2006, 16 additional soil samples were collected from eight borings to further delineate the extent of soil contamination at the site.

In August, 2008, prior to bioremediation agent application, baseline groundwater samples were collected and analyzed. Subsequently, between March 2009 and April 2009, three subsurface applications of bacteria/nutrients (Catalina BioSolutions “Biocritters”) were completed. In July

2009, quarterly groundwater monitoring activities were resumed following the application activities and adjusted to semi-annual monitoring in April 2011.

In accordance with the FDEP response to the Remedial Action Status Summary, semi-annual groundwater sampling occured from April 2011 through June 2013. The December 2012 groundwater monitoring event yielded no exceedances of GCTLs for the first time. In June

2013, the FDEP issued a letter requiring additional groundwater monitoring before site close-out could be awarded. Additional sampling events occurred in June 2013 and January 2015.

Samples were analyzed for PAHs, TRPH, and Florida Residual Petroleum Organic (FL PRO)

VOCs. Laboratory analysis from the COCs reported all concentrations beneath GCTLs in these monitoring events. The January 2015 results indicated that No Further Action (NFA) criteria had been met.

In January 2016, a Site Rehabilitation Completion Report (SRCR) requesting NFA was submitted to FDEP using previous sampling results as justification. In a March 2016 letter, the

FDEP stated that the SRCR did not meet requirements for a NFA without institutional controls and requested additional data to substantiate that the soils at the site meet the NFA condition.

The letter also requested preparation of a Memorandum of Decision for the site. In October

2016, three additional soil borings were installeded and six soil samples were collected to further delineate the extent of soil contamination.

In January 2017, eight soil samples were collected from four new borings to address data gaps.

Soil sample results identified petroleum-related contaminants exceeding SCTLs in several borings. The extent of soil contamination above industrial SCTLs was determined to be adequately delineated. A Confirmatory Soil Sampling Report t completed in September 2017 recommended preparation of a Limited Scope Remedial Action Plan (LSRAP) for a source removal for petroleum related compounds exceeding industrial SCTLs followed by the implementation of land use controls.

All site soil with petroleum exceedances of the industrial SCTLs have been excavated and disposed offsite at the Waste Management – Chesser, Subtitle D landfill in Folkston, Georgia. Groundwater laboratory analytical results from the September 2019 sampling event were reported above GCTLs in the groundwater sample collected from monitoring well 12-MW-1. Based on the October 2019 Partnering

Meeting discussions, it was agreed that prior to closure, additional groundwater assessment activities are required be completed. It was determined the that a workplan, dig permit, the installation of three, 12-foot monitoring wells, one year of PARM sampling and reporting for six monitoring wells and a Land Use

Controls Implementation Plan (LUCIP) was needed.

For FLC Jacksonville NFD12 JP-5 WEST OF PS2, the following actions are required to be

3.1.1 Semi-Annual Groundwater Sampling – [PPW Reference Item 017] three (3) monitoring well(s). This task includes low flow sampling of currently installed wells on a semi-annual basis using a peristaltic pump, laboratory analysis for TPH and VOCs. The contractor shall include review of existing reports/studies/relevant documents in its proposal. The contractor shall dispose of Investigation Derived Waste (IDW) shall be handled as notated in the

PWS 2.15.1 IDW.

3.1.2 Well Abandonment – [PPW Reference Item 018]

schedule 40

Wells are installed in unconsolidated overburden

3.1.3 Site Closeout – [PPW Reference Item 019]

Meetings include one kickoff meeting, one review meeting, and one regulatory review meeting

NFD13 DIESEL FUEL MARINE PIPELINE LEAK

A release occurred in June 1999 when fuel was pumped into an open-ended pipe. Source removal was completed near the discharge point. Product was recovered from temporary wells and a recovery well (RW-1) was installed during source removal but was not utilized for product recovery. The recovery well was sampled and contained naphthalene above groundwater cleanup standards.

Between March 2005 and May 2007, the DFM Area was treated with Fenton’s Reagent eight times. During treatment, groundwater monitoring was conducted from April 2005 to August

2008. FDEP approved a Remedial Action Plan Modification in March 2009, allowing bioremediation materials (Catalina Biosolutions “Biocritters”) application to the subsurface during April 2009, June 2009, and August 2009.

In March 2010 and June 2010, FDEP reviewed monitoring reports and stated that additional soil removal may be required to reduce groundwater contaminant concentrations below the GCTLs.

This was based on rebound of TRPH in groundwater.

The June 2010 sampling event represented the 3rd event of monitoring following completion of subsurface bioremediation application in August 2009. In December 2010, soil samples were collected from the smear zone adjacent to PZ-3, PZ-5, and PZ-6. Analysis of one soil sample collected adjacent to PZ-5 identified exceedance of the TRPH SCTL for commercial and industrial contact (SCTL-C/I) (10,400 milligrams per kilogram [mg/kg], this exceeded the standard established at 2,700 mg/kg). Additional soil sampling was conducted during the

September 2011 event to further delineate TRPH in the smear zone.

In August 2012, groundwater concentrations exceede the GCTLs in the sample collected from

PZ-3. TRPH was detected at concentrations less than the GCTL in all lateral, upgradient, and downgradient wells. It was determined that the residual TRPH concentrations were isolated to the area of the 2000 source removal based on the analytical results.

In November 2014, soil assessment activities were conducted to better determine the extent of contamination at the site. Three soil borings were completed and soil samples were analyzed for

TRPH. Concentrations of C11-C22 aromatics at the 1 foot and 2 foot depth intervals were reported in boring NFD13-MADEP-3. Contaminant levels exceeded residential, commercial/industrial, and leachability SCTLs. Based on this assessment, additional soil samples at step out locations from soil boring NFD13MADEP-3 at 1 feet intervals to the groundwater table were recommended. Analysis would include TRPH speciation to further delineate the extent of the elevated C11-C22 aromatics fraction above SCTLs.

In November 2014, semi-annual groundwater monitoring identified TRPH concentrations below the GCTL (5 mg/L) in the three wells sampled (MW-2, MW-5, and MW-6). The conclusion was that residual TRPH concentrations were isolated to the area of the 2000 source removal.

Continuation of semi-annual groundwater monitoring was recommended, including reducing the number of monitoring wells and piezometers to PZ-5, PZ-6, and PZ-7 and reducing parameters to TRPH for the next semi-annual groundwater monitoring event.

In 2015, two rounds of semi-annual groundwater monitoring in NFD 13 at PZ- 3, PZ-5, PZ-6, and PZ-7 were ordered with analysis of TRPH only. Site Assessment was scheduled in 2015 to collect soil samples at step-out locations from soil boring NFD13MADEP-3 and analyzed for the

TRPH speciation to further delineate the extent of the elevated C11-C22 aromatics fraction above the SCTLs and to monitor natural attenuation.

In an October 2015 letter, FDEP requested installation of an additional well and 12 soil borings with analysis of groundwater for TRPH and PAHs in soil to characterize the lateral and vertical extent of contaminants found near the location of the 1999 removal action.

In January 2016, groundwater samples were collected from six monitoring wells (PZ-5, PZ-7, MW-3, MW-5, MW-6R, and MW-7). During this event, TRPH was detected in monitoring well

MW-07 at concentrations above GCTLs.

In April, May and June 2016, 13 additional soil borings were advanced around existing soil boring locations to delineate the direct exposure industrial SCTL exceedances of TRPH. Soil sample analysis indicated that TRPH and Benzo (a) pyrene equivalent impacts exceeding industrial SCTLs had been adequately delineated.

In July 2016, a Limited Scope Remedial Action Plan (LSRAP) to conduct source removal was completed. The purpose was to excavate all accessible contaminated soil to approximately 6 feet below land surface (bgs) to reduce contaminant levels below the SCTLs for benzo(a)pyrene equivalents (industrial SCTL of 0.7 mg/kg) and total recoverable petroleum hydrocarbons

(industrial SCTL of 2,700 mg/kg). This would bring the site into compliance with Chapter 62-

770 of the Florida Administrative Code (FAC). The LSRAP was approved by FDEP in

February 2017.

In September 2016, a project was awarded to conduct source removal activities, including excavation of contaminated soil, confirmation sampling, and Oxygen Release Compound (ORC) injections. In January 2017, a second project was awarded to remove asbestos piping and replace asphalt paving. The source removal and two Post Active Remediation Monitoring

(PARM) groundwater sampling events of three micro-wells (13-MW-7R, 13-MW-8, and 13-

MW-9) were been completed (January and April 2017). Analytical results of the first and second

PARM groundwater sampling events showed TRPH concentrations above the GCTLs in micro-wells 13-MW-8 and 13- MW-09. The report documenting the April PARM event conducted in recommended conducting two monthly 2-day groundwater extraction events and continuing groundwater monitoring for the site. The results of the source removal activities (excavation of

697.8 tons of petroleum-impacted soil) and collection of soil confirmation samples were documented in a Source Removal report dated June 2017. The report recommended No Further

Action with conditions for soil and one year of quarterly (4) PARM events at micro-wells MW-

7R, MW-8, and MW-9; analyzed for PAHs and TRPH.

In September 2017, based on the exceedances observed in the second and third quarter PARM events, conducting groundwater extraction events followed by the continuation of PARM was recommended, which FDEP concurred with in two approval letters dated 20 September for the

2nd quarter PARM and 27 September 2017 for the 3rd quarter PARM.

Groundwater sampling results from February 2018 event showed a second consecutive PARM event with no contaminants above GCTLs. The report for the February 2018 PARM event recommended NFA for the site with conditions due to residual contaminated soil exceeding residential SCTLs. In January 2018, FDEP approved the use of an Alternate Soil Cleanup Target

Level (ASCTL) for benzo(a)pyrene and benzo(a)pyrene equivalents for the FLC Jacksonville sites.

The site has met criteria for closure but was not approved until site 16 has met criteria for closure as well.
