Problems/Comments

Lake Louise Recreation Camp was used as a recreational fishing and boating facility for the Air Force personnel and their dependents from 1955 to 1965; the two portions totaled approximately 25 acres. The camp consisted of a lodge, dining hall, airmen's dormitory, boat shop and fueling point, a generator building, freshwater intake pump house, shower house, small sleeping cabins, and a picnic area. The property had limited use due to lack of good sports fishing, the 3-4 hour drive from Anchorage, and the build-up of other Air Force recreation sites. When the 1964 earthquake caused extensive damage to the improvements, the Air Force discontinued use of the site in 1965. Improvements at the site were demolished in 1971. Concrete slabs and perimeter foundations remain; building debris was removed or buried. Diesel contaminated soil up to 8,500 mg/kg was detected near the generator building. Eight areas of concern have been identified, some with CERCLA COCs and some without. CERCLA AOCs have PCBs and lead: dining hall leach field, lodge area UST, shower area UST, and power plant area. Non-CERCLA AOCs have DRO and PAHs: drum and debris area, and the tank trailer area. It was determined no further action was required at the gravel pit area and generator shed and boat shop area. A ROD was signed in 2012.

2/27/2015	Document, Report, or Work plan Review - other	The Alaska Department of Environmental Conservation (ADEC) received a report titled Final Lake Louise Recreation Camp Groundwater Monitoring Report 2014 Environmental Long Term Management and Remedial Action-Operations at Multiple 611 Civil Engineering Squadron Locations on January 27, 2015. The report presents the results of the 2014 annual groundwater monitoring sampling event. Groundwater samples were collected from ten wells and analyzed for diesel range organics (DRO), polycyclic aromatic hydrocarbons (PAH), and a one-time baseline sampling event for monitored natural attenuation (MNA) parameters (nitrate/nitrite, total organic carbon, ammonia, iron, manganese, chloride, fluoride, sulfate, and sulfide). Water quality parameters such as dissolved oxygen, temperature, conductivity, and pH were also recorded. Four of the ten wells sampled (MW01, MW02, MW03, and MW07) showed an increase in DRO contaminant concentrations over a three to four year period. A Mann-Kendall statistical analysis performed on the data from all ten wells indicates that the contaminant plume may be in an advancing state in the vicinity of these four wells and may be diminishing at other wells.	Meredith Savage
4/29/2015	Site Characterization Report Approved	The Alaska Department of Environmental Conservation (ADEC) received an electronic copy of the report titled 2014 Cleanup Activities Report, Lake Louise Recreation Camp on April 27, 2015. The report documents the tank and soil removal activities conducted in September and October, 2014 at the former Lake Louise Recreation Camp (LLRC). A tank measuring approximately 17 feet x 6 feet x 3 feet was removed from the Off-Shore Debris Area. No petroleum odor or sheen was observed during removal; the tank was wrapped in a polyethylene liner and transported to a metal recycling facility in Anchorage, AK. A total of 162.16 tons of petroleum contaminated soil was removed from five areas within the Tank Trailers Area (TTA) north of the gravel access road and confirmation soil samples were taken from each area. Four additional locations south of the access road were also sampled. Sample analytical results show that contamination exceeding approved cleanup levels (CULs) remains in three of the five excavated areas: • Excavation #1: diesel range organics (DRO) with Silica Gel cleanup at 16,000 mg/kg and 29,000mg/kg. • Excavation #2: DRO at 26,000 mg/kg and DRO-Silica Gel at 14,000 mg/kg, 1-methylnapthalene at 410,000 mg/kg, 2-methlynapthalene at 680,000 mg/kg, and naphthalene at 310,000 mg/kg. • Excavation #5: DRO-Silica Gel at 73,000 mg/kg and 33,000 mg/kg, 1-methylnapthalene at 300,000 mg/kg, 2-methlynapthalene at 520,000 mg/kg, and naphthalene at 210,000 mg/kg. Analytical results from the four hand boring samples taken south of the gravel access road between 1.5 feet and 3.5 feet below ground surface showed no petroleum hydrocarbon contamination exceeding cleanup levels. However, given the proximity and concentrations of the contamination remaining immediately north of the access road, ADEC is requesting as a condition of approval that additional sampling be conducted in 2015 south of the access road at and deeper than the elevation of the confirmation samples exceeding approved CULs collected at Excavations #2 and #5. ADEC understands that additional soil removal may be conducted at Excavation #1 in 2015, but that further excavation of contaminated soil at Excavations #2 and #5 may not be possible without compromising the integrity of the gravel access road.

This work plan addendum proposes to continue the excavation and characterization efforts which began following the 2012 Record of Decision. Activities in 2015 will be conducted to remove, transport, thermally treat, and dispose of an estimated 50 cubic yards of petroleum, oil, and lubricants (POL)-contaminated soil, and to collect up to five analytical samples. DEC has commented that this work will only meet the requirements of an interim removal action, per 18 AAC 75.330, even though this work may be intended as the final removal action. Additional characterization, confirmation sampling, and potentially, additional removal actions will be required to produce the information needed for DEC to make a site determination. To scope this anticipated effort DEC requests that the remaining soil and groundwater contamination and monitored natural attenuation progress be evaluated following the 2015 fieldwork. The DEC approval letter for the 2014 Cleanup Activities Report, Lake Louise Recreation Camp, included as a condition of approval that additional sampling be conducted in 2015, in areas south of the access road at and depths below the elevation of the confirmation samples exceeding approved CULs collected at Excavations #2 and #5. This work plan does not propose work that will satisfy these conditions. With this in mind, please note that DEC will not approve further work at this site following the 2015 IRA which does not satisfy previously stated conditions for approval.	Monte Garroutte
2/26/2016	CERCLA ROD Periodic Review	DEC Approved the 2015 Five-Year Review Report for Lake Louise Recreation Camp (Site OT001) Lake Louise, Alaska. The ROD for this site was signed in 2012, therefore this is the first Five Year Review (FYR). All of the CERCLA contaminants have been removed from the site. Petroleum contamination remains in the groundwater and soil at the site, and the ROD specifies that FYRs include a review of both the remaining CERCLA and petroleum compounds. DEC concurs with the recommendations in the FYR that a groundwater data gaps investigation, soil characterization effort, and soil contamination removal be completed at the site, and recommends that a follow-on evaluation of the former drum locations indicated in the Lake Debris and Soil Removal Report be completed as part of the soil or groundwater characterization effort.	Monte Garroutte
7/6/2016	Document, Report, or Work plan Review - other	DEC Approved the 2015 Cleanup Activities Report, Lake Louise Recreation Camp, Alaska. This report details the performance of Remedial Action-Construction activities at the Lake Louise Recreation Camp (LLRC) in 2015. Contaminated soil excavation and removal were performed at the one Environmental Restoration Program site OT001 associated with the LLRC in September 2015. The 2015 activities were a continuance of previous remedial operations at the site beginning in 2012. A total of 75 tons (50 cy) of petroleum-contaminated soil were removed from three excavations. Laboratory analysis of the confirmation soil samples indicated that the excavation effort removed the extent of the impacted soil at Excavation 2. However, soil with petroleum concentrations exceeding the PALs for diesel-range organics (DRO) and naphthalene were detected in the analytical samples along the excavation extents at Excavation 1 and Excavation 5.	Monte Garroutte
10/13/2016	Document, Report, or Work plan Review - other	DEC Approved the Supplemental Work Plan, 2016 Remedial Action Operations, Land Use/Institutional Control, Lake Louise Recreation Camp, Site OT001. Activities include installing two Land Use Control (LUC) warning signs at OT001 Tank Trailer Area warning the public that contamination is present, collecting groundwater samples from 10 monitoring wells, and collecting 10 soil samples. If groundwater is present during soil sampling, one monitoring well will be installed. This sampling effort includes sampling across the road from Excavation 5.	Monte Garroutte
6/15/2017	Document, Report, or Work plan Review - other	Approved Final 2016 Summary Report of Remedial Action Operations, Land Use/Institutional Control documenting the long-term management activities conducted in 2016 at Lake Louise Recreation Camp including sampling nine groundwater monitoring wells, analyzing ten soil samples, installing an additional groundwater monitoring well, and installing notification signage for land use control. Approval letter also recommends, as discussed with USAF, continued soil removal at Excavation #1 and #5 and adequate scoping for soil removal to occur until sampling indicates the soil removal goal has been met, as several removal actions conducted previously at this site were scoped too small to complete the remediation effort.	Gretchen Caudill
3/1/2018	Update or Other Action	The Air Force notified DEC that pentachlorophenol was detected in the groundwater above Table C cleanup levels, ranging from 0.051j to 22 ug/L, in the petroleum contaminated areas of the site. DEC discussed these detections with the Air Force and determined that it would be appropriate to continue tracking this contamination under the OT001 site. Next actions are to sample soil for pentachlorophenol and sample the entire well network to delineate the contaminant extent.	Monte Garroutte

Update or Other Action

The Alaska Department of Environmental Conservation (ADEC) Contaminated Sites- Federal Facilities Environmental Restoration Program received an application for a Groundwater Use Determination requesting that the shallow groundwater beneath the Lake Louise Recreational Camp be deemed unsuitable as a drinking water source under Title 18 AAC75.350 on May 21, 2010. We have completed our review of the application and we approve of the “350” determination that eliminates the migration to groundwater pathway from being considered a complete exposure pathway at the site as long as the impacted soil/water are on Air Force property and surface waters are not impacted or threatened. The remedy will need to include soil cleanup to the ingestion/inhalation standards and demonstrating that any groundwater plume is steady state or shrinking and contaminant concentrations are decreasing, along with appropriate ICs.

The Alaska Department of Environmental Conservation (ADEC) received a report titled Final Lake Louise Recreation Camp Groundwater Monitoring Report 2014 Environmental Long Term Management and Remedial Action-Operations at Multiple 611 Civil Engineering Squadron Locations on January 27, 2015. The report presents the results of the 2014 annual groundwater monitoring sampling event. Groundwater samples were collected from ten wells and analyzed for diesel range organics (DRO), polycyclic aromatic hydrocarbons (PAH), and a one-time baseline sampling event for monitored natural attenuation (MNA) parameters (nitrate/nitrite, total organic carbon, ammonia, iron, manganese, chloride, fluoride, sulfate, and sulfide). Water quality parameters such as dissolved oxygen, temperature, conductivity, and pH were also recorded. Four of the ten wells sampled (MW01, MW02, MW03, and MW07) showed an increase in DRO contaminant concentrations over a three to four year period. A Mann-Kendall statistical analysis performed on the data from all ten wells indicates that the contaminant plume may be in an advancing state in the vicinity of these four wells and may be diminishing at other wells.

Site Characterization Report Approved

The Alaska Department of Environmental Conservation (ADEC) received an electronic copy of the report titled 2014 Cleanup Activities Report, Lake Louise Recreation Camp on April 27, 2015. The report documents the tank and soil removal activities conducted in September and October, 2014 at the former Lake Louise Recreation Camp (LLRC). A tank measuring approximately 17 feet x 6 feet x 3 feet was removed from the Off-Shore Debris Area. No petroleum odor or sheen was observed during removal; the tank was wrapped in a polyethylene liner and transported to a metal recycling facility in Anchorage, AK. A total of 162.16 tons of petroleum contaminated soil was removed from five areas within the Tank Trailers Area (TTA) north of the gravel access road and confirmation soil samples were taken from each area. Four additional locations south of the access road were also sampled. Sample analytical results show that contamination exceeding approved cleanup levels (CULs) remains in three of the five excavated areas: • Excavation #1: diesel range organics (DRO) with Silica Gel cleanup at 16,000 mg/kg and 29,000mg/kg. • Excavation #2: DRO at 26,000 mg/kg and DRO-Silica Gel at 14,000 mg/kg, 1-methylnapthalene at 410,000 mg/kg, 2-methlynapthalene at 680,000 mg/kg, and naphthalene at 310,000 mg/kg. • Excavation #5: DRO-Silica Gel at 73,000 mg/kg and 33,000 mg/kg, 1-methylnapthalene at 300,000 mg/kg, 2-methlynapthalene at 520,000 mg/kg, and naphthalene at 210,000 mg/kg. Analytical results from the four hand boring samples taken south of the gravel access road between 1.5 feet and 3.5 feet below ground surface showed no petroleum hydrocarbon contamination exceeding cleanup levels. However, given the proximity and concentrations of the contamination remaining immediately north of the access road, ADEC is requesting as a condition of approval that additional sampling be conducted in 2015 south of the access road at and deeper than the elevation of the confirmation samples exceeding approved CULs collected at Excavations #2 and #5. ADEC understands that additional soil removal may be conducted at Excavation #1 in 2015, but that further excavation of contaminated soil at Excavations #2 and #5 may not be possible without compromising the integrity of the gravel access road.

Interim Removal Action Approved

The Alaska Department of Environmental Conservation (DEC) completed review of the Work Plan Addendum, 2015 Lake Louise Recreational Camp, Remedial Action and Construction Activities, on September 15, 2015. This work plan addendum proposes to continue the excavation and characterization efforts which began following the 2012 Record of Decision. Activities in 2015 will be conducted to remove, transport, thermally treat, and dispose of an estimated 50 cubic yards of petroleum, oil, and lubricants (POL)-contaminated soil, and to collect up to five analytical samples. DEC has commented that this work will only meet the requirements of an interim removal action, per 18 AAC 75.330, even though this work may be intended as the final removal action. Additional characterization, confirmation sampling, and potentially, additional removal actions will be required to produce the information needed for DEC to make a site determination. To scope this anticipated effort DEC requests that the remaining soil and groundwater contamination and monitored natural attenuation progress be evaluated following the 2015 fieldwork. The DEC approval letter for the 2014 Cleanup Activities Report, Lake Louise Recreation Camp, included as a condition of approval that additional sampling be conducted in 2015, in areas south of the access road at and depths below the elevation of the confirmation samples exceeding approved CULs collected at Excavations #2 and #5. This work plan does not propose work that will satisfy these conditions. With this in mind, please note that DEC will not approve further work at this site following the 2015 IRA which does not satisfy previously stated conditions for approval.

CERCLA ROD Periodic Review

DEC Approved the 2015 Five-Year Review Report for Lake Louise Recreation Camp (Site OT001) Lake Louise, Alaska. The ROD for this site was signed in 2012, therefore this is the first Five Year Review (FYR). All of the CERCLA contaminants have been removed from the site. Petroleum contamination remains in the groundwater and soil at the site, and the ROD specifies that FYRs include a review of both the remaining CERCLA and petroleum compounds. DEC concurs with the recommendations in the FYR that a groundwater data gaps investigation, soil characterization effort, and soil contamination removal be completed at the site, and recommends that a follow-on evaluation of the former drum locations indicated in the Lake Debris and Soil Removal Report be completed as part of the soil or groundwater characterization effort.

DEC Approved the 2015 Cleanup Activities Report, Lake Louise Recreation Camp, Alaska. This report details the performance of Remedial Action-Construction activities at the Lake Louise Recreation Camp (LLRC) in 2015. Contaminated soil excavation and removal were performed at the one Environmental Restoration Program site OT001 associated with the LLRC in September 2015. The 2015 activities were a continuance of previous remedial operations at the site beginning in 2012. A total of 75 tons (50 cy) of petroleum-contaminated soil were removed from three excavations. Laboratory analysis of the confirmation soil samples indicated that the excavation effort removed the extent of the impacted soil at Excavation 2. However, soil with petroleum concentrations exceeding the PALs for diesel-range organics (DRO) and naphthalene were detected in the analytical samples along the excavation extents at Excavation 1 and Excavation 5.

Update or Other Action

The Air Force notified DEC that pentachlorophenol was detected in the groundwater above Table C cleanup levels, ranging from 0.051j to 22 ug/L, in the petroleum contaminated areas of the site. DEC discussed these detections with the Air Force and determined that it would be appropriate to continue tracking this contamination under the OT001 site. Next actions are to sample soil for pentachlorophenol and sample the entire well network to delineate the contaminant extent.

DEC approved the Final 2018 Long Term Monitoring Program Report, Lake Louise Recreation Camp Site OT001, Lake Louise, AK, Dated August 2019. Monitoring and inspection activities included collecting groundwater samples from eleven wells at Site OT001, and inspection of well integrity and checking for unauthorized access at the Power Plant Area and Tank Trailer Area. Groundwater samples indicated that diesel range organics continue to exceed Record of Decision cleanup levels in six of the eleven wells, and 1-methylnapthalene and naphthalene exceedances were present in one well. Mann-Kendall analysis indicated that diesel range organics may be increasing in one well, but the other wells exhibited no trend. The site inspection revealed that repairs are necessary for several of the wells, but no evidence of unauthorized access was observed.

DEC approved the Final Work Plan, 2019 Removal Action, Site OT001, Lake Louise Recreation Camp Site OT001, Lake Louise, AK, Dated September 2019. Removal and treatment of up to 250 cubic yards of contaminated soil from the OT001 Tank Trailer Area will be undertaken. Photoionization detector and PetroFlag test kit field screening will be used to guide the excavation. The excavation will target areas where previous sampling has indicated that diesel range organics and polycyclic aromatic hydrocarbons exceed the Record of Decision cleanup levels. Additionally, confirmation sampling will include pentachlorophenol as an analyte in order to determine if previous detections of this contaminant were caused by laboratory issues. The resulting contaminated soil will be transported to Alaska Soil Recycling in Anchorage, Alaska for treatment and disposal.
