Update or Other Action |
Received document dated June 16, 2008 titled 'Soil Treatment Plan, Kincaid Park Biathlon Range, Anchorage, Alaska.' Document included results of soil samples collected on April 20, 2008 from intact range documenting total lead levels as high as 68,300 mg/kg and TCLP results of up to 456 mg/L. Soil having TCLP results for lead of 5 mg/L or more is a characteristic hazardous waste. The document included the estimated volume of lead-contaminated soil to be excavated as 125 cubic yards (~188 tons), noting that if lead shot remains in the soil after excavation, additional soil may need to be removed. Consultant proposed that bulk lead fragments remain in the soil matrix to be treated, in the belief that a pyromorphite shell would form around bulk lead fragments. The document also noted that soil had already been excavated from the range target area. |

Document, Report, or Work plan Review - other |
DEC letter issued that approves hydroseeding of west slope of the soccer field as an interim stabilization measure to bring the site into compliance with the existing SWPPP (Storm Water Pollution Prevention Plan) and CGP (Construction General Permit) for the construction project. Approval to hydroseed was requested in an email dated May 29, 2009 by KPG's consultant and was previously requested in a work plan dated May 12, 2009. DEC's letter notes that sediment sampling results have been provided to DEC and results did not exceed DEC's most stringent 18 AAC 75.345 method two migration to groundwater cleanup levels for lead or antimony. The letter also makes a record of the agreement between KPG and DEC that DEC will withhold issuing a review letter for the plan submitted on April 16, 2009 until EPA's requirements are better known. |
Eileen Olson |
| 6/2/2009 |
Update or Other Action |
Analytical results for sediment sampling done on May 18, 2009 received. The results show that sediment sampling requested by DEC in a letter dated May 8, 2009 did not exceed the most stringent cleanup levels for lead and antimony. These results were referenced in DEC's letter issued on the same date, with DEC's non-objection to grading and hydroseeding of the sediment. |
Eileen Olson |
| 6/3/2009 |
Update or Other Action |
DEC notified KPG by email that appropriate dust suppression for potentially contaminated soil at the site will be required as long as soil at the site remains susceptible to wind erosion, and until final site control measures are in place, and requested that KPG provide a description of the dust suppression measures that will be taken and maintain a log of dust suppression actions. The notification and requests were made because it appears likely that completion of the soccer field will be delayed beyond this summer pending resolution of regulatory issues, leaving soil exposed at the site surface that is susceptible to fugitive dust production and wind erosion and transport. |
Eileen Olson |
| 6/4/2009 |
Document, Report, or Work plan Review - other |
DEC received and approved responses from KPG for site controls including 1) driven-post fencing and signage that are being put in place, with perimeter fencing to be completed by June 11th. Site access controls were requested in DEC's May 28th letter to KPG; 2) a description of dust suppression measures as requested in DEC's 6/3/2009 email; KPG responded that water will be applied on days when it does not rain and a record will be kept of water application. DEC responded that the dust suppression measures should be sufficient but are performance-based to the extent that monitoring should be done to determine whether the goal of suppressing dust is met; and 3)a health and safety plan for workers and site visitors as requested in DEC's May 28th letter to KPG. |
Eileen Olson |
| 6/9/2009 |
Document, Report, or Work plan Review - other |
DEC email approval of fencing plan received by email dated 6/8/2009 with diagram of proposed fencing.

Update or Other Action |
DEC email with attached photos to KPG as follow-up to 6/11 site visit recommending that access and signage issue be addressed in a manner that prevents or at a minimum discourages access over the weekend (email was sent on a Friday). The email noted that although DEC observed that quite a bit of fencing that was to completed by 6/11 was up, bicyclists and other passersby were freely accessing the site during the DEC site visit. |
Eileen Olson |
| 6/14/2009 |
Site Visit |
Site visit by DEC staff Sunday p.m. Fencing was observed to have been completed since the last site visit of 6/11 and done according to the fencing plan received on 6/8/2009. In approving the plan DEC agreed that some areas of the site perimeter did not require fencing because heavy vegetation and nearly impassible ground surface conditions already adequately prevented access. "Keep Out" and other signs were in place along the fenced areas. |
Eileen Olson |
| 6/16/2009 |
Meeting or Teleconference Held |
DEC staff met at the site with KPG, MOA, construction contractor and environmental consultant representatives to discuss site issues including actions taken to control site access and the next steps with respect to addressing site contamination.

Update or Other Action |
DEC was copied on an email from EPA counsel to KPG that commented on the Kincaid Status Report by KPG dated June 17, 2009. EPA noted that the site is subject to RCRA and stated that the April 16th work plan submitted to ADEC does not appear to provide for sufficient characterization. EPA stated that a sampling plan must identify areas where the bulk soil is contaminated as well as areas where intact bullets and larger lead fragments are present, and that once characterization is completed a corrective action plan must be developed for removing contamination where feasible and evaluating measures for any portions of the unit for which clean closure is not feasible. |
Eileen Olson |
| 6/24/2009 |
Update or Other Action |
ADEC was copied on a letter to EPA from KPG's consultant. The letter revises information provided to the EPA in MOA and KPG's April 10, 2009 submittal that responded to EPA's information request. The letter evaluates lead usage at the range and concludes that projectile fragment mass in the cut/fill area of the site is small relative to the total lead removed. |
Eileen Olson |

Potentially Responsible Party/State Interest Letter |
PRP letters were sent notifying three business entities for the first time that under state law they are “potentially responsible parties” (PRPs), meaning that that they may be financially liable for contamination associated with the Kincaid Park former biathlon range site in Anchorage. The entities are the environmental consulting firm Shannon & Wilson, Inc., Landscape Design North, Inc. (LDN) and Roger Hickel Contracting, Inc. Each of the PRP letters includes an information request that should assist the agencies in determining the fate (i.e. location) of lead-and antimony-contaminated soil and bullet slugs and fragments associated with the range. Responses to the information requests are due on April 2, 2010. CS is particularly interested in verifying that potentially contaminated soil was not used as fill at seven soccer fields that were constructed at Kincaid Park in 2008 concurrent with the soccer stadium preconstruction earthwork at the former range site. |

Meeting or Teleconference Held |
10:15-~11:30: Staff participated in a teleconference with EPA’s Jan Palumbo and Matt Hemry of S&W. During the call Mr. Hemry stated his opinion that all of the fill areas would have to be excavated regardless of the results of the planned investigation, and said he would advise his client that everything must be dug up (as part of the investigation). Later in the day EPA provided an email clarifying that EPA and DEC do not concur with this conclusion, and noting that the purpose of the site investigation is to identify the extent of the contamination at the site, so that the contaminated areas may be selectively addressed; and further noting that the intent of this approach is to minimize costs by defining the specific areas that are contaminated, so that costly excavation and treatment or processing of large volumes of clean fill is unnecessary. |

DEC transmitted by email a draft limited site characterization plan to involved parties on this date as an example of an approvable site characterization work plan. The plan was prepared at the request of KPG and the MOA and addresses only the largest fill area, Fill A1. Staff noted in the email accompanying the draft plan that 1) EPA expects to complete a review of the plan by Monday or Tuesday of next week (June 28 or 29), but has communicated their position that EPA cannot approve any plan that has not gone through the public notice and comment process; 2) Therefore EPA’s involvement in the plan review process will not constitute approval of the plan, and 3) This leaves the parties in the position of completing characterization work that carries a risk of not sufficiently meet EPA’s requirements, but that should expedite completion of the project; or delaying work until a closure plan has been through the 30-day public notice process and determined to be satisfactory by EPA.

EPA transmitted Final DEC workplan with EPA edits to involved parties on this date. The attachment to the email is dated 6/28/2010. The workplan introduction states that the "limited site characterization workplan is intended to be an example of a plan that could be
approved by the DEC, and could potentially be part of a Resource Conservation and Recovery
Act (RCRA) plan submitted to EPA. The plan is not comprehensive and includes only one area
of the Kincaid Park Former Biathlon Range site, as requested of the Alaska Department of
Environmental Conservation (DEC) by the Municipality of Anchorage (MOA) and the Kincaid
Project Group (KPG). Other areas of the site requiring investigation and any standard plan
elements not included in the section below will need to be added by the environmental consultant
for the Kincaid parties, and a comprehensive workplan submitted that addresses the entire site." |

Response to 6/30/2010 DEC plan received this date by DEC and EPA from KPG and the other parties identified by EPA as liable parties. The email accompanying the comments states as follows: "KPG and MOA, along with their respective environmental consultants, Shannon & Wilson Inc. (S&W) and Alta Geosciences Inc. (Alta), have thoroughly reviewed the work plan section provided by DEC, and accept the DEC and EPA premise that characterization of the Fill A1 Area must comprise direct assessment of a substantial volume of soil, using a combination of visual observation, field screening, and analytical samples. Accordingly, we accept this section of the plan, subject to the modifications noted here and in the attached more specific comments from S&W. The two primary proposed modifications are replacing the trenching component with near-complete removal of fill soil for screening and/or sampling, and application of currently-promulgated cleanup levels as the appropriate standards for clean closure." |

Additional communications received and responded to re plan prepared by DEC finalized 6/30/2010: On July 20th Shannon & Wilson, consultant for the Kincaid Project Group (KPG) proposed conducting a second X-Ray Fluorescence (XRF) field screening correlation study to determine a threshold XRF value below which lead contamination would be considered to be below the applicable cleanup levels set by the U.S. Environmental Protection Agency (EPA) and DEC. Determining such a threshold would allow soil that meets the field screening level to be immediately re-used as fill without laboratory analysis or confirmation sampling. On July 22nd DEC, in consultation with EPA, responded that sufficient XRF field screening and laboratory analytic data is available to set the threshold for XRF readings at the detection limit for the XRF Analyzer but no higher than 25.1 parts per million (ppm or mg/kg) lead, which was the highest detection level recorded for during the first correlation study in March 2010. The next step is the submittal of a complete workplan by Shannon & Wilson for agency review and approval. |

Site Visit |
Staff Weimer and Olson met with Dwayne Adams, former LDN principal, Shannon & Wilson representatives and Scott Dunlap of RHC (earthwork contractor)to walk through all areas of the soccer field and stadium project area that were disturbed by cut, fill and grading operations. LDN made the case that a berm at the west side of the south end of the base for the artificial turf field is not a built-up berm but was graded from an elevated area, and therefore will not need to be excavated to depth, but will require at least surface evaluation for lead fragments. Also discussed with RHC representative the applicability of the Construction General Permit to earthwork related to environmental cleanup. Since the CGP is expected to remain in effect through the end of construction, compliance by the involved parties with the requirements of the CGP should be sufficient to ensure that stormwater runoff doesn't transport potentially contaminated soil offsite. If it is not additional actions may be required under the Contaminated Sites regulations. |

Document, Report, or Work plan Review - other |
DEC and the US Environmental Protection Agency (EPA) separately provided review comments to the Kincaid Project Group (KPG) and other involved parties for the plan submitted August 10th titled “Draft Work Plan for Site Characterization & Interim Removal Action”, prepared by Shannon & Wilson. KPG’s plan is intended to be comprehensive in that all disturbed areas of the site, including cut, fill and graded areas will be evaluated. CS staff met with the involved parties on August 16th to ensure that all disturbed areas will be included in the characterization plan. DEC’s requests for corrections and revisions to the plan largely pertain to agreements made with the involved parties during the site visit, so it is anticipated that the turnaround time for submittal of a final plan by Shannon & Wilson will be short, allowing work to begin within the next two weeks. The plan proposes to excavate virtually all fill areas at the site, and the reliance on a Niton X-ray fluorescence (XRF) analyzer for field analysis will allow characterization of contamination and the interim removal of lead and lead-contaminated soil to take place nearly concurrently.

Press Release issued by EPA this date regarding the site and Consent Agreement and Final Order (CAFO):"Firing range cleanup agreement means Kincaid Park soccer field construction can move forward Contact Info: Kevin Schanilec, RCRA Compliance Officer, (206) 553-1061, schanilec.kevin@epa.gov Tony Brown, EPA Public Affairs, (206) 553-1203, brown.anthony@epa.gov (Seattle --- Oct. 7, 2010) The Municipality of Anchorage, Kincaid Project Group, Land Design North and Roger Hickel Contracting, Inc., have agreed to complete the clean up of lead-contaminated soil at Kincaid Park in Anchorage, Alaska under a settlement announced today by the Environmental Protection Agency. According to Edward Kowalski, EPA’s Director of Compliance and Enforcement in Seattle, today’s cleanup agreement will allow the construction of a new and safer soccer field at the site of a former firing range in the park. “This settlement is great news for Anchorage-area youth, for the environment, and for the community as a whole,” Kowalski said. “It means the cleanup will get done and ultimately children and their families will have a safe place to play without risk of exposure to lead-contaminated soil.” Today’s consent agreement requires the parties to submit a cleanup plan to EPA within 90 days. Once the plan is approved, it will be implemented as soon as practicable. Under the settlement, the parties also agreed to pay a penalty of just over $63,000 for violations of federal hazardous waste management rules also known as Resource Conservation and Recovery Act. Kincaid Park is a 1,500-acre City Park owned by the Municipality of Anchorage. A biathlon shooting range operated at the park from approximately 1988 to 2007. The shooting range was contaminated with lead from bullets, with lead soil levels ranging as high as 68,000 parts per million. In May 2008, during construction of a soccer field at the former shooting range, The Kincaid Project Group and two contractors moved lead-contaminated soil at the site, thereby generating approximately 30 tons of lead-contaminated hazardous waste soil and debris. The contaminated material was stored and disposed of on-site without treatment and without proper testing. Lead contamination from other areas of the shooting range was also disturbed and spread over approximately 4-acres without prior testing to determine whether the lead levels would be classified as hazardous waste. Some of the waste has since been properly disposed of, but additional cleanup is required in order for the site to be safely used by the community. Lead is highly toxic to people, especially children, when ingested or inhaled. Short term exposure can cause brain and kidney damage. Long term exposure can damage the blood and central nervous system." |

Document, Report, or Work plan Review - other |
Agency letter by DEC and EPA issued that modifies the March 2011 Closure Plan to expand the Area of Contamination (AOC) to include areas outside
the Area of Contamination (AOC) established for the site based on observations of lead beyond the perimeter of the AOC established in the Closure Plan. In some cases lead was found
using a metal detector, but in most cases lead was identified during visual surveys.
In addition to modifying the AOC the letter requires that a plan be submitted by July 1, 2011 for investigation and cleanup of the newly added area.

A.M. Site visit by staff Robert Weimer met with ALTA field staff who described work done since Friday morning. Continued excavating Fill Areas A2/A3. The grass had been cut along the trail to the former stockpile area and much of the pea gravel had been removed. Discussed with ALTA field staff that there is an area of soil in A3 near the south target line that still needs to be removed, there were areas where the pea gravel was not removed to the fill surface, some areas of cut grass had over an inch of cut material covering (the cut material was not collected), and the grass cutting was not conducted along the trail to the north. ALTA field staff said that work would be completed and that the removed gravel areas with be screened with the metal detector. |

A.M. Site visit by staff Robert Weimer met with ALTA field staff who described work done since Thursday morning and planned work for the next few days. They plan to begin removing surface soils of Fill Area A1 today where they found lead fragments in the past will be placed in the visibly contaminated pile needing treatment after excavation. ALTA field staff said that all of the under 400 ppm lead lab samples passed TCLP so those soils were being used as backfill in the Fill A2 area. They had conducted a metal detector and visual sweep of the areas besides and along the trail to the west and southwest of the site. The areas along the paved trail did not have lead, but the dirt trail areas did. Over 200 metal detector hits were identified along the dirt trail, over 40 besides the trail, and over 40 leading to and at the former stockpile area. ALTA will investigate how deep the disturbed soil is in all of those areas that could have lead fragments. They were preparing additional stockpile areas for the visually contaminated soils. |

They plan to continue removing surface soils of Fill Area A1 where they found lead fragments in the past will be placed in the visibly contaminated pile needing treatment after excavation. They were still getting metal detector hits on the new surface, and have dug additional 3 inch lifts. They had about 30 locations with lead after the first lift, then about 15 of them after the next lift. They were beginning to assess the next lift below those 15 locations. At one of the locations they recovered about a dozen lead slugs. The lead recovered was intact slugs or partially flattened slugs. They were preparing additional stockpile areas for the additional visually impacted soils. |

They have begun excavation the deeper soils of the Fill Area A1, starting at the southwest corner. So far all of the XRF readings were non detect. They have encountered a lot of buried logs on top of the former ground surface including areas under the field. The excavator confirmed that when they constructed the field they dozed over the existing trees and brush prior to backfilling, but they tried to push the trees outside of the field area, so most of them would be buried under the slopes. |

A.M. Site visit by staff Robert Weimer met with ALTA field staff who described work done since Friday morning and planned work for the next few days. They continue to excavate the deeper soils of the Fill Area A1, starting at the southwest corner. So far all of the XRF readings were non detect or below 50 ppm. They have encountered a lot of buried logs on top of the former ground surface including areas under the field. The excavator confirmed that when they constructed the field they dozed over the existing trees and brush prior to backfilling, but they tried to push the trees outside of the field area, so most of them would be buried under the slopes. They removed approximately 40 cubic yards (~60 tons) of visually/metal detector hit contaminated soil from and besides the south trail, and the former stockpile area. Excavation continued until no visual or metal detector hit soils remained. The areas were then checked with the XRF on a 5X5 or closer grid, and all readings were below 50 ppm. Those areas were then backfilled with clean soil after excavation was completed. ATLA estimated that there is a total of 575 cubic yards (~826 tons) of contaminated soil currently stockpiled to be treated, the rest of the excavated soil has had XRF readings <50 ppm or analytical samples demonstrating that it meets default cleanup levels. |

A.M. Site visit by staff; Robert Weimer met with ALTA field staff who described work done since Friday morning and planned work for the next few days. They continue to excavate the deeper soils of the Fill Area A1, starting at the southwest corner and working north. They have had a few more detectable XRF readings in the excavated soil with the highest being 30 ppm. They continue backfilling portions of the Fill Area A1 that they have already checked out as being <50 ppm lead on the XRF. Organic soils that are being backfilled are being placed beneath the slope and not under the field. Did a visual walkthrough of some of the Cut A area outside of the current green flagged areas. Recovered 23 flattened lead fragments visible on the surface between rows 110 and 170 and columns F and N, including one flattened lead fragment from area F-130 of the lead fragment map, which previously had no lead fragments detected or recovered during the metal detector sweep. ALTA hopes to complete excavation of Fill Area A1 by the end of this week or early next week. ALTA expects to submit a treatment plan for treating stockpiled lead-contaminated soil soon; treatment may take place concurrently with excavation of remaining lead-contaminated soil.

They continue to excavate the deeper soils of the Fill Area A1, starting at the southwest corner and working north. They have had a few more detectable XRF readings in the excavated soil with the highest being around 12 ppm. They continue backfilling portions of the Fill Area A1 that they have already checked out as being <50 ppm lead on the XRF. They are getting into an area that has a lot of organic soils under the excavated slope. These organic soils so far have all been <50 ppm lead on the XRF and are being reused as backfill beneath the slope and not under the field. Discussed with ALTA field staff that care should be taken so that the remaining contamination in the Cut A Area is not graded into soils being backfilled in the Fill Area A1. |

ALTA field staff said that they would be submitting a treatment plan soon and hope to have the treatment chemicals in about 2 weeks. They plan to begin excavating the Cut A soils by early next week to clear up an area to construct the soil treatment cells, they would then move the contaminated soils into the cells, and then complete the assessment and cleanup of the Cut A area under the stockpiles. Discussed with ALTA field staff that there are still some gravel berms that need to be removed and assessed under for lead, so additional lead contaminated areas may be found that need cleanup. They will also provide a corrected figure showing the letters and numbers along the grid lines as they are in the field. They hope to complete all of the assessment work by the end of July, and complete the treatment of the lead contaminated soil by mid August. |

Document, Report, or Work plan Review - other |
Agency (DEC and EPA) review letter issued following review of ALTA memorandum dated July 13, 2011 "Cut A Surface Remediation Plans" submitted on July 14, 2011. The memorandum proposed to reduce the area of excavation based on the apparent lack of observed or detected lead in certain areas. The Agency review letter notified the parties that the Agencies did not approve the modifications proposed in the memo, and that the conditions found in the Agencies' June 30, 2011 review letter remain in effect because the surface survey methods used resulted in incomplete detection and removal of lead fragments at and near the ground surface; therefore the assessment and excavation requested in the Agency letter dated June 30th is necessary. |

These organic soils so far have all been <50 ppm lead on the XRF and are being reused as backfill beneath the slope and not under the field. ALTA field staff said that their XRF had broken down and the manufacturer had sent them an older model while theirs was being repaired. The older model XRF takes about twice as long for readings so during those few days they were only able to excavate and check about half as much soil as normal, which has resulted in the completion date for the project being pushed back a couple of days. They plan to begin excavating the Cut A soils after they finish with the Fill A1 soils next week. They hope to complete all of the assessment work by early August, and complete the treatment of the lead contaminated soil by mid/late August. |

A.M. Site visit by staff Robert Weimer. Because of the recent rains and muddy soil conditions they were not going to be conducting field work this day They hope to resume work on Saturday and may work on Sunday. Since Wednesday morning they had excavated additional soils of the Fill Area A1. They hope to finish excavating and backfilling the Fill Area A1 by Wednesday next week, then start removing the Cut A soils. They hope to complete all of the assessment work by mid August, and complete the treatment of the lead contaminated soil by late August. During the site walkthrough a flattened projectile was observed on the ground surface, photographed, and recovered by DEC staff from grid square 170-Y, which is an area where lead fragments were not detected during the metal detector sweep. During the site visit DEC observed that grid squares 320-O, 320-N, and 330-N appear to have been excavated and backfilled as part of the Fill Area A1 site work. |

They plan to remove the liners from stockpile areas 2 and 3 so they can assess and remove contaminated soil from those areas. The surveyor estimated that 520 cubic yards of soil are currently stockpiled to be treated, which is less than the original 577 cubic yard estimate. With the contaminated soil remaining in the Cut A area, ALTA estimates that they will have between 900 and 1000 cubic yards of the contaminated soil that will need to be treated. We discussed that during soil treatment that care needs to be taken so the liner underneath is not damaged. |

A.M. Site visit by staff Robert Weimer. Staff met with ALTA field staff who described work done since Monday morning and planned work for the next few days. They continue to excavate additional soils of the Fill Area A1. They hope to finish excavating and backfilling the Fill Area A1 today or early Thursday, then start removing the Cut A soils. They hope to complete all of the assessment work by mid August, and complete the treatment of the lead contaminated soil by late August. They plan to remove the liners from stockpile areas 2 and 3 so they can assess and remove contaminated soil from those areas.

Reviewed August 10th attachment to email by ALTA Geosciences of Cut A figure and proposed field procedures for the Cut A soil assessment and removal. Talked with ALTA staff about corrections needed to the Cut A figure (add Y170 and surrounding area, and correct the size and location of the stockpile areas) and the proposed field procedures. ALTA staff said they would make the corrections and submit revisions.

A.M. Site visit by staff Robert Weimer. Staff met with ALTA field staff who described work done since Wednesday morning and planned work for the next few days. They have finished assessing Fill Area A1, except for the section along the base that they plan to assess after completing the Cut A area cleanup. They hope to finish backfilling the other areas of Fill Area A1 with clean soils this week. They were starting to remove the liners at of the former stockpiles 2 and 3, and the grid squares were being marked in preparation to beginning the Cut A area cleanup. ALTA staff mentioned that the start of the soil treatment may be delayed because they are still in discussions with the vendor for the treatment chemicals as to the amount and type of chemicals to be used to treat the lead contaminated soils, and thus the chemicals have not been ordered yet. Once the chemicals are ordered it will take about a week for them to arrive at the site. |

A.M. Site visit by staff Robert Weimer. Staff met with ALTA field staff who described work done since Friday morning and planned work for the next few days. They have begun to excavate the soils at the base of the Fill Area A1, all readings so far were below 50 ppm. They have also started excavating Cut A soils along row A-B north of stockpile 5, ALTA field staff said that all XRF reading were below 50 ppm and no visible or metal detector lead was found. The thickness of the Cut A soils in that row was about 2 to 3 inches. The liners have been removed from stockpile areas 2 and 3, a visual walk through by ADEC staff of those area found and recovered 23 projectile fragments. This included two grid squares (K-L 40-50, and L-M 100-110) that had not had visible projectile fragments found during the previous metal detector survey. ALTA field staff said that FESI requested additional contaminated soil be shipped to them so they could do more treatability design testing, which will result in delays in getting the treatment of the soils completed. FESI is still evaluating whether the FESI dry product (which is available in Anchorage) or the FESI wet product (which has to be shipped from Seattle) would work better in treating the lead contaminated stockpile soils. ATLA now hopes to complete all of the assessment work before the end of August, and complete the treatment of the lead contaminated soil by mid/late September.

They have completed the assessment of the soils at the base of the Fill Area A1, all readings were below 50 ppm. They have also started excavating Cut A soils and hope to have all of it done except for the soil under stockpile 5 by Saturday, ALTA field staff said that they had two XRF reading that were above 50 ppm below where they removed visible lead in the Cut A area. There were also a few areas where they need to remove additional soil in the Cut A area to get to the natural ground surface. They were just finishing removing the last of the clean soil from stockpile 1. ALTA field staff said that FESI is still testing the soil they sent them to determine the best product and application rate for treating the lead contaminated stockpile soils. ATLA hopes to complete all of the assessment work before the end of August, and complete the treatment of the lead contaminated soil by mid/late September. |

Afternoon site visit by staff Robert Weimer. Staff met with ALTA field staff who were evaluating different mixing methods for conducting a pilot test of using 1 percent calcium phosphate (fertilizer) and 6 percent lime (pH buffer) to treat the excavated contaminated soil currently stockpiled at the site. ATLA selected 10 cubic yards of some of the most highly contaminated soil to do the pilot test on. They attempted to use two different types concrete mixing trucks to mix the soils, but the soils had too much silt in them to run through or load into the trucks efficiently. They plan to attempt mixing on a liner using a loader bucket tomorrow morning to see if that will work better |

ATLA selected 10 cubic yards of some of the most highly contaminated soil to do the pilot test on. They successfully mixed the soil on a liner using a loader bucket. ATLA will collect confirmation samples from the 10 cubic yards of pilot test soil and have them analyzed in the laboratory for total lead and TCLP lead. ALTA hopes to submit the lab results to DEC and EPA by September 7, 2011 and submit a treatment plan for review and approval soon after that. They are prepared to begin treatment as soon as they have an approved plan. Once they begin treatment they estimate it should take less than 2 weeks to process and treat all of the stockpiled contaminated soils. |

Update or Other Action |
ADEC and EPA (the Agencies) received the "Pilot Test Results" from environmental consultant ALTA that reports the results of analysis of lead-contaminated soil treated with a mixture of phosphates and calcium carbonate compounds, with analysis done for total lead and for leachable lead by the EPA Method 1311 Toxic Characteristic Leaching Procedure or TCLP. The soil treatment is intended to stabilize lead in the soil so that the soil will not fail the TCLP for lead. Soil from the Kincaid site that does not fail the TCLP for lead is not a hazardous waste and can be disposed of at the Anchorage Regional Landfill. |

Document, Report, or Work plan Review - other |
EPA and ADEC approval letter for ALTA Geosciences, Inc. revised "Soil Treatment Plan...September 2011" received September 19, 2011. The revised plan replaces a previous version having the same title that was transmitted to EPA and ADEC on September 12, 2011. The revised plan was prepared and submitted in response to EPA and ADEC comments received by ALTA on Sept. 19, 2011. Approval of the plan constitutes approval to treat and test lead-contaminated soil for the sole purpose of disposal of the treated soil at a RCRA Subtitle C or D landfill. The approval notes that soils that pass the TCLP for lead may be disposed of at the Anchorage Regional Landfill (a Subtitle D landfill). Soils that do not pass the TCLP must be disposed of at a Subtitle C landfill. |

Document, Report, or Work plan Review - other |
EPA and ADEC issued a joint letter of non-objection to soccer field project work taking place following completion of soil excavation, treatment and transport. The letter responded to an inquiry by a Municipality of Anchorage representative regarding whether project work associated with the soccer field and stadium project at the Kincaid Park Former Biathlon Range site
can proceed as soon as all excavation, treatment and removal of lead contaminated soil at the site is complete. Project work includes placing gravel over the surface of the project area, trenching to create draining systems, and other earthwork and construction related to completion of the soccer field complex. EPA and ADEC had no objection to project work beginning
immediately upon removal of all contaminated soil from the site, with the conditions that 1) the Parties keep the Agencies apprised in a timely manner ofwork in progress within the Area of Concern (AOC), and 2) any soils excavated within the AOC must remain within the AOC and the post-excavation location of such soils tracked until the Closure Report and Closure Certification for the site have been received and accepted by the Agencies. Excavation and placement of any soil excavated within the AOC must be documented and the Agencies notified of such excavation and placement of excavated soil within one week of excavation. |
