Romenesko reported in a memorandum dated 9/23/91 lead samples results were collected from the Red Dog Mine on 6/19/91 and analyzed for total lead. 20 samples ranged from 342 to 48,800 mg/kg lead. Samples were collected around the mill site CSB and the roadway to the airport. The report also noted that Cominco had their consultant ENSR collect soil samples at the port site both on land and the sea bottom, along the roadway from the port site to the airport at prescrbed intervals, and at locations of previous concentrate spill locations; also, that the ENSR sampling was observed by JMM INgineers who was hired by AIDEA. The Cominco results were not available for the DEC report. |

Update or Other Action |
In a letter dated 11/9/01 to Commissioner Brown, the Trustees for Alaska noted that they had attended a meeting hosted by Klein last week in which he gave a presentation on "Problem Identification, Evaluation, and Resoluttion Framework" as part of the Red Dog Mine/road Fugitive Dust Project Technical Team. The framework would guide the work in developing an appropriate resonse to the heavy metals contamiation at the Red Dog Mine site.
The letter provided comments on the proposed problem statement and noted that if the "proposed problem statement" was followed, it would not produce a legally or environmentally adequate response.
Specifically, the Trustees asked what is the meaning of "off site" and expressed their concern that under the proposed problem statement that contamination could be allowed to contaminate NANA's land thoughout the life of the mine so long as the contamination does not migrate off NANA land. The letter also noted that the fugitive dust into the environmental constitutes a release that is reportable and needs to be cleaned up.
Based upon this, the Trustees requested the Commissioner to review ADEC's proposed problem statement and accompanying assessment and cleanup goasls and adjust them to reflect applicable law. |

Update or Other Action |
In response to the Trustees of Alaska's 11/9/01 letter regarding questions concerning potential contamination from the Red Dog Mine, at the mine and in areas off site, Commissioner Brown responded in a letter dated 1/14/02.
Commissioner Brown's letter noted that there is a Fugitive Dust Technical Team tasked to inquire whether the dust and attendant metals pose a risk to people through any pathway of exposure, or to the environment surrounding the active mine operation, inlcuding the port site and road.
Specific on-site contamination concerns are being evaluated by CSP to determine what cleanup actions may be necessary.
Lastly, the letter noted that ADEC will continue to solicit public involvement in the various environmental issues that arise in the regulation of mine operations. |

Update or Other Action |
In a letter dated 2/13/02 the Trustees of Alaska responded to Commissioner Brown's 1/14/02 letter, which was in response to the Trustee's 11/9/01 letter concerning the scope of work to be undertaken by the Red Dog Mine/Road Fugitive Dust Project Technical Team.
The Trustees noted that they reprsented the Alaska Community Action on Toxics, Northern Alaska Environmental Center, and Center for Science and Pulbic Participation. The letter noted that they were concerned with legal issues including that ADEC had as early as 1991 known of the contamination but did nothing and that Teck Cominco apparently did nothing to cleanup the contamination (reference to the ADEC Rominesko 9/23/91 memo on a DEC sampling inspection at Red Dog Mine). The letter requested that ADEC initiate the contaminated sites assessment process. The letter also noted that ADEC not wait until reclamation to address the releases.
The other issue the letter raised was that public participation is requested during the cleanup process and noted that it is required under 18 AAC 75.325(j). The letter suggested that ADEC form a "restoration advisory board."
Lastly the letter requested clarification regarding the processs of the Fugitive Dust Project. |

Update or Other Action |
On 6/25, after discussing with Shock DEC and E&E's comments, DEC issued a letter with comments regarding its review of Exponent's “Draft Phase I Field Sampling and Analysis Plan for the DMTS Fugitive Dust Risk Assessment” dated June 2003.
The draft workplan was provided to CSP by Exponent via e-mail on June 18 and 19, 2003.
The letter noted that CSP understands that the pre-shipping season marine sampling is planned to begin on Monday June 23, 2003 because the shipping season begins in early July. The rest of the field program is planned to begin on July 14, 2003.
One of the chief comments was that CSP suggests that the Phase I Field Sampling and Analysis Plan (FSP) provide further information within the workplan to identify the existing data gaps explicitly and how the proposed sampling scheme will fill the data gaps. Table 4 provided a rationale but without describing the specific data gaps for which the data is being collected. Without this information, it was not possible to judge the merits of the proposed sampling. For example, there is no explanation how the data will be used with the existing data and why the samples are being collected at the locations selected. This section provides only generic explanations about the selection of sampling locations and the rationale for the number of samples to be collected in any area. The information provided is insufficient for the reader to evaluate whether the data from the proposed sampling locations actually will fill the data gaps. If the sampling proposed in this FSP is based on comments and concerns expressed by DEC and other parties on the risk assessment work plan, it should be explained how the proposed sampling satisfies these comments and concerns. Lastly, insufficient explanation has been provided about how reference locations were selected.
The letter noted that upon review of DEC's comments, Exponent would contact Sundet to discuss how Teck Cominco will address the comments and finalize the workplan. |

Teck Cominco agreed to pay $33,000 in civil penalties to settle a complaint by the Environmental Protection Agency alleging ore was discharged into Alaska's northwest coast in 2002.
The EPA's complaint against mine operator Teck Cominco Alaska Inc. followed an investigation launched when a mine worker reported that ore was pushed by winds off a conveyor belt into the Chukchi Sea. Red Dog, the world's largest zinc mine.
The Anchorage Daily News article reporting the settlement on February 10, 2005 noted
"Sometimes our best leads come from people in the community who observe activities that don't look right," Kim Ogle, an EPA water compliance manager in Seattle.
The agreement was announced Wednesday February 9, 2005.
Between mine records and a videotape supplied by the worker, EPA investigators found three instances of ore discharge in August 2003. Teck Cominco's wastewater discharge permit doesn't cover ore falling from the conveyor belt.
Jim Kulas, the mine's environmental supervisor, said Teck Cominco readily acknowledged that "fugitive dust" was swept into the ocean as the finely ground ore was being loaded from the dock to barges in extremely windy conditions. The worker who made the video, in fact, turned the tape over to company officials, who reported the incident to the EPA and Alaska Department of Environmental Conservation, Kulas said.
"We regret the situation and have taken steps necessary to correct the problem," he said.
In 2003, the company spent $2.6 million for a conveyor belt containment system, Kulas said. Another $1.3 million was spent to upgrade containment equipment on two barges, he said.
EPA spokesman Jeff Philip said its settlement with the company was completed Monday February 7, 2005. |

Update or Other Action |
On 9/21/05, DEC and Teck Cominco signed a Memorandum of Understanding relating to fugitive dust generated at the Red Dog Mine. The MOU was designed around dealing exclusively with the Mine generated fugitive dust. While most if this work will be inside the mine's ambient air boundary and not subject to the on-going fugitive dust risk assessment, the MOU does address a small area where data thus far indicates that mine dust has been deposited in the mountain saddle just outside the boundary. Earlier in 2005, Teck Cominco informed DEC that an investigation within the mine's ambient air boundary and just adjacent to it found elevated lead and zinc concentrations in the soil/tundra and stressed vegetation.
The MOU states that Teck Cominco will perform the following studies: snow drift studies, tundra "soil" sampling, particle fate analysis; ambient and fugitive monitoring for total suspended particulates and vegetation; engineering studies to reduce fugitive dust emissions including a control options study, course ore stockpile building study, Mine Concentrate Storage Building (CSB) /Truck Loading Facility Fugitive Dust Reduction Review looking at the feasibility of using a baghouse dust collection system in the Mine CSB; and perform a source apportionment and particle deposition modeling study. |

Throughout that time period, many of the comments were satisfactorily addressed. After the majority of comments had been addressed with satisfactory responses, DEC and TC entered into Comment Resolution to resolve the remaining comments. During Comment Resolution, to facilitate a more timely review, a revised document with redline/strikeout changes showing was made available by TC via web meetings for DEC and its contractor to review and provide further comments. Upon satisfactory completion of review and revisions to the red-line/strikeout document, on 10/30/07 we requested that Teck Cominco finalize the risk assessment document. On 11/19/07, Exponent provided the revised risk assessment report to DEC for our final review. DEC posted the report on our webpage to allow for public review. On 11/20, Exponent provided several corrected figures, which we replaced in the previously submitted document on our webpage.
Upon review of the document provided on 11/19 and 20/07, DEC approved of the final risk assessment report. DEC also requested that TC provide to DEC a risk management plan to address risks to ecological receptors that were identified in the report. The report did not identify any current risk to humans. DEC's approval letter also noted that we understand that TC will be coordinating with various stakeholders on the development of the plan. DEC's letter noted that while we understand that this may require a number of meetings with the various stakeholders, DEC is requesting that a draft of the management plan be provided to us by June 2008.
The draft and final risk assessment reports, as well as public comments on the draft risk assessment report and other reports, can be found on our webpage at http://www.dec.state.ak.us/spar/csp/sites/reddog.htm

Meeting or Teleconference Held |
On 2/25/08, Sundet and other stakeholders attended the Ikayuqtit Team meeting at NANA Corporation. The focus of the meeting was to update stakeholders on the findings of the risk assessment and next steps to address the fugitive dust issue. The presentation was provided by Teck Cominco (TC) and TC noted that it would be holding a workshop in Kotzebue on 3/24-26/08 for stakeholders to discuss the fugitive dust issue and seek input from the stateholders on the development of a risk management plan. The plan would address the area outside of the mine's solid waste boundary that was subject to the RA, the area within the mine's boundary subject to the MOU with the State. The plan would also address fugitive dust concerns that would be subject to the mine's closure permit. Also during the meeting, NPS provided a presentation on an overview of its field work conducted in 2005-2007 in the DMTS. |

Meeting or Teleconference Held |
On 5/7/08, a teleconference occurred between Teck Cominco, DEC and EPA regarding comments that EPA had conveyed onto DEC via email on 12/31/07 and also onto TeckCominco. The two concerns were in followup to two of EPA's original comments regarding the draft risk assessment report. These two comments were on the fractional intake to large home range species such as caribou and the exposure areas (such as the port or road corridor) as stated in the final risk assessment. Discussion in the teleconference focused on how Exponent/Teck Cominco will address those comments in a supplemental assessment. |

| 6/15/2010 |
Public Notice |
On 6/15/10, DEC public noticed Teck's two draft implementation plans that address technical issues regarding findings of the fugitive dust risk assessment at Red Dog Mine: the Monitoring Plan and the Remediation Plan. DEC received the draft plans via email from Exponent on 6/7/10. On 6/15, DEC posted the notice on DEC's webpage and requested that comments be submitted between 6/15 through 5:00 p.m. 8/2/10. The notice informed individuals that the two draft plans can be found on DEC's webpage at: http://www.dec.state.ak.us/spar/csp/sites/reddog.htm. The draft plans are part of Teck's Risk Management Plan (RMP) for effective management of fugitive dust issues at the mine. The draft RMP was public noticed by ADEC in September 2008 and the RMP stated that six subplans would be developed and submitted at a later date. Teck provided a Communication Plan that DEC did not public notice but posted on its webpage. In addition to the Communication Plan, the other five plans are: Dust Emissions Reduction Plan; Remediation Plan; Monitoring Plan; Uncertainty Reduction Plan; and a Worker Dust Protection Plan. The RMP defines and will guide actions to minimize the potential for effects to human health and the environment from fugitive dust from the Red Dog operation, including the mine, road, and port. The draft RMP plan lays out objectives to achieve this overall goal. It also defines the scope for preparation of individual implementation plans. Earlier in December 2007, DEC conditionally approved of Teck's Final DMTS Fugitive Dust Risk Assessment report that Teck develop and implement a management plan to address the risks identified in the risk assessment report. As part of the public notice, DEC will have the notice published in the Anchorage Daily News (6/18, 20 & 22); Fairbanks Daily News Miner (6/19, 20 & 22); and Arctic Sounder (6/18, 6/20 & 22). In addition, DEC sent out letters to 38 identified stakeholders informing them of the draft plans and included the public notice and encouraged that they provide comments regarding the draft plans.

On 12/20/11, DEC provided general comments to Teck regarding their "Draft Report 2008 Moss Sampling Event, Red Dog Mine Moss Study" dated 7/13/2009. The draft report was prepared by Rare Earth Science, LLC. DEC received the report via e-mail from Teck's consultant Scott Shock of Exponent on 4/15/2011. Due to the general nature of these comments, additional details were not submitted. General comments included: outside of the solid waste boundary around the mine, the site has been determined to be a contaminated site subject to 18 AAC 75 regulations and as such a work plan was required to be submitted and approved by DEC prior to work commencing; a matrix of potentially impacted receptors, compounds of concern, target levels, and monitoring and/or remediation actions have not yet been provided, as requested. This matrix was first discussed for inclusion in the DMTS Fugitive Dust Risk Assessment but deferred to the Risk Management Plan (see Summary of Issues Deferred to the the Risk Management Plan, attachment to the 6/19/2009 letter from DEC to Wayne Hall). In relation to the subject moss study, DEC informed Teck that the matrix could be used to put in context the results from the moss study; it was unclear how information from this study will be used in the future; and, units for the multi-increment sampling were very large and do not meet DEC's expectations for MI sampling to be representative of the metal deposition areas. DEC requested a response to its comments by 2/15/2012. |

Document, Report, or Work plan Review - other |
On 1/6/2012, CSP provided comments to Teck regarding their Fugitive Dust Risk Management, Worker Dust Protection Plan prepared by Exponent for Teck Alaska Incorporated (Teck) and submitted to ADEC via e-mail by Rebecca Hager of Teck on 10/19/2011. The Worker Dust Protection Plan is in follow-up to risk management Objective 7, “Protect worker health” from the Draft Risk Management Plan. The Worker Dust Protection Plan’s goal is, “To minimize worker exposure to fugitive dust, provide ongoing monitoring of exposure, and ensure a comprehensive communication system.” This goal is related to worker’s health and is not directly associated with ADEC’s Contaminated Sites Program oversight of the Red Dog Mine site. Given this, specific comments were not developed for this plan. ADEC's letter noted that while ADEC did not have specific comments on this particular plan, as part of the Risk Management Plan for the Red Dog Mine site, all implementation plans need to be provided to CSP in draft form for review and comment. It was our understanding that the Contaminated Sites Program did not receive the draft of the Worker Dust Protection Plan. ADEC's letter noted that in the future, it requested the following:
• Teck ensures all draft and final implementation plans be provided to Rich Sundet of ADEC’s CSP.
• Teck provides Rich Sundet of DEC with documentation that the Worker Dust Protection Plan was provided to appropriate worker health organizations for review and comment.

On 1/31/2012, in response to several issues regarding the risk management plan, Rebecca Hager of Teck along with her consultant Scott Shock of Exponet met with Sundet. Also present were Jason Rutman and Alison Kelly of NANA Regional Corporation, and on teleconference was Stephanie Pingree Buss ADEC's term contractor and Jody of Exponent. Primary discussion focused on the matrix of potentially impacted receptors, compounds of concern, targe levels, and monitoring and/or remediation actions that ADEC previously had requested in its June 19, 2009, November 8, 2010 and December 20, 2011 letters. |

Update or Other Action |
On 6/22/12, ADEC provided comemnts to Teck and the Ikayuqtit Team regarding "Red Dog Mine 2012 Vegetation Monitoring (in accordance with the Solid Waste Permit) Proposed Efforts for 1st Follow-up Survey for a Determination of Trend Regarding Fugitive Dust Effects" (hereinafter referred to as the Proposal) dated April 2012. The document was prepared by Cedar Creek Associates, Inc. (Cedar Creek) for Teck and submitted to the Ikayuqtit Team, which the Contaminated Sites Program (CSP) is part of) by Rebecca Hager of Teck on 4/25/2012. Because the Proposal was submitted in accordance with the Solid Waste Permit, Sundet provided the Proposal to Tim Pilon of ADEC who is managing the permit for ADEC. Comments reflect CSP’s and Mr. Pilon’s comments. Methodology for vegetation sampling is consistent with the 2010 event and as described in the Draft Fugitive Dust Risk Management Monitoring Plan (June 2011). According to the April 2012 document, monitoring is required by the ADEC Solid Waste Permit. The results of the monitoring plan will also be used to evaluate potential risks identified in the DMTS Fugitive Dust Risk Assessment (November 2007). Consistency between the 2010 and subsequent sampling events is important for comparability; therefore, no changes to the sampling methodology are recommended for monitoring the vegetative community as follow-up from the risk assessment. For the sake of clarity, ADEC requests that Waste Management Permit No. 0132-BA0002 be referenced or cited at least once and that “Solid Waste Permit” be replaced with “Waste Management Permit.” Another comment noted that the Fugitive Dust Risk Management Plan (RMP) as it applies to the mine site (i.e. excluding the DMTS and Port) is required as part of the Red Dog Mine Waste Management, Reclamation and Closure Monitoring Plan (May 2009), and compliance with the Red Dog Mine Waste Management, Reclamation and Closure Monitoring Plan is required by the Waste Management Permit; therefore, a statement of this connection would maintain some clarity regarding jurisdiction of the Waste Management Permit versus the entire RMP.

On 4/5/13, ADEC provided comments to Teck regarding its review of the Response to Comments on the Uncertainty Reduction Plan (September 2012) and Fugitive Dust Risk Management, Uncertainty Reduction Plan (Final; October 2012) prepared by Exponent for Teck and submitted to DEC by you via e-mail on 9/27/2012. ADEC noted that the Uncertainty Reduction Plan followed from risk management Objective 5, Conduct research or studies to reduce uncertainties in the assessment of effects to humans and the environment, from the Draft Risk Management Plan (2008). The Uncertainty Reduction Plan’s goal is, “To identify and prioritize prospective research or studies to reduce uncertainties in the assessment of effects of fugitive dust to humans and the environment.”
ADEC provided comments on the Draft Uncertainty Reduction Plan on 5/1/2012. ADEC noted in its 3/29th letter that Teck addressed these comments satisfactorily, except as indicated below. Many of the general and specific comments required changes to Tables 2 and 3 of the subplan. The response to comment document indicates the much of the requested additional information was incorporated into Tables 2 and 3. This is an appropriate place for this information and ADEC find that the tables in the final subplan to be complete.
Specific comments to Teck's response were regarding general comment #2 and reiterated that the matrix of potentially impacted receptors, compounds of concern, target levels, and monitoring and/or remediation actionsneed to be incorporated into the Risk Management Plan (RMP) and the implementation subplans for monitoring and remediation. The other ADEC comment was in regards to general comment #6 in which Teck noted that it would be monitoring for metals concentrations and included in the 2013 Annual Report, whereas ADEC noted that a responsible person is required to submit a sampling and analysis plan for approval by DEC under 18 AAC 75.360 and meets the requirements outlined in 18 AAC 75.355. |

Site Visit |
ADEC's Englund and Wu conducted a site visit at Red Dog Mine, approximately 90 miles north of Kotzebue. The visit consisted of an overview tour of the mining area, gravel haul road, and port facility of the mine where fugitive dust from mining activities has been an ongoing concern. A risk management plan is currently in development to address risks and uncertainties identified in the risk assessment. A key issue has been assessing the risk to the vegetation community and determining how much of that risk is due to the physical impact of fugitive dust and how much is due to the zinc and lead content in the dust. Environmental staff from the mine and Exponent staff from Seattle were on hand to discuss issues on setting action levels, as well as work plans for moss monitoring study (in lieu of soil monitoring) and for addressing community concerns about metal concentrations in caribou bone. |

Meeting or Teleconference Held |
Chris Eckert of Teck along with his consultant Scott Shock of Exponent met with ADEC staff Weimer, Wu, and Englund. Also present were Alison Kelly of NANA Regional Corporation, and on teleconference was Stephanie Pingree Buss ADEC's term contractor and Rebecca Hager of Teck. Primary discussion focused on the site history and the results of the 2013 sampling work. The mine started in 1989 and is currently scheduled to operate until 2032+. Metals contamination has been identified on land owned by NANA, the State of Alaska, and the federal government (Cape Krusenstern National Monument).
The berry and surface water sampling report is to be submitted by the end of 2013. Teck is putting together a Risk Management Plan (RMP) that will address all of the requests in ADEC letters since June 19, 2009. We discussed that all work conducted at the request of or for the ADEC CS Program, need work plans pre-approved by ADEC CS, collection/interpretation/preparing of all field data by a qualified impartial third party, and in standalone reports that meet the requirements in 18 AAC 75. We discussed that NANA staff would not meet the 3rd party requirements.
Teck stated that the concentrations in the ore concentrate have been consistent year to year so they are going to look into why the metals concentrations have increased in some of the dust fall monitoring stations. They will include pH testing with future vegetative and tundra sampling. Some of the sampling Teck is currently doing (such as roadway metals concentrations and dust fall stations) is being conducted every two months. Teck was proposing not to establish alternative cleanup levels for the contaminated areas. Teck was also proposing dropping moss sampling every 6 years, but to conduct tundra sampling every 3 years instead.

Document, Report, or Work plan Review - other |
On September 4, 2016 marine sediment samples were collected at 8 locations and analyzed for cadmium, lead and zinc to evaluate temporal changes in sediment metal concentrations due to activities at the DMTS (DeLong Mountain Regional Transportation System) port and barge-loading facilities. Up to 0.26 mg/kg cadmium, 17.4 mg/kg lead, and 89 mg/kg zinc in the samples collected. These results are below the Effects Range-Low (ER-L) guideline values (cadmium 1.2 mg/kg, lead 46.7 mg/kg, and zinc 150 mg/kg) developed by Long et al. (1995) for marine sediment. |

Red Dog 2017 Fugitive Dust Risk Management Plan Annual Report. The report documented communication actions, road surface sampling, application of dust control products to the tailings beaches/road/port, dust control equipment upgrades at the mine and port, dust fall jar monitoring at the mine/road/port, work site blood lead monitoring, current dust reduction efforts, reseeding of a previous zinc concentrate spill along the road at MS-13 that occurred on October 3, 2015, and vegetative community monitoring in 2017. A caribou tissue study, a bone/marrow cooking study, marine sediment sampling, and moss tissue monitoring are planned to be conducted in 2018. |

Meeting or Teleconference Held |
A virtual meeting was held with environmental staff with Red Dog Mine, and our technical staff to discuss current focus of soil and sediment sample efforts, revisions to the existing work plan (last reviewed and approved in 2014), land ownership questions along the Delong Mtn Transporation System apart from the Port and the Mine/Mill Complex. Site visits are planned for late in the upcoming summer for PPR staff to perform a spill drill, visit historic spill sites, and overlap with the third-party consultant who will be conducting soil sampling to satisfy required survey data every three years (sediment sampling will occur next year on an every-two-year basis). |

Site Visit |
DEC staff visited the mine and conducted site and sampling effort inspections during a three-day visit (August 29 through August 31). Environmental staff with the mine hosted our visit. Staff with the consulting company overseeing the monitoring and sampling efforts were present, as well as consulting biologists with two different consultants that would be conducting the soil sampling effort while we were on site. Two different methods were demonstrated, samples were collected from representative quadrant plot and transect sample sites. One site along the sampled transect location was sampled between tussock tundra demonstrating the depth of soil in a typical tussock sample site. Sample data will be compared between the two different methods (first was a soil coring device with disposable sample sleeve, and the second was a disposable sample knife). Remediated sites where there have been truck rollover releases of lead or zinc concentrate were visited along the road corridor. Remediation strategies have evolved over the years changing from excavation and reseeding to vacuuming the concentrate and letting the site recover independently. |

Document, Report, or Work plan Review - other |
The 2022 Annual Report for the Fugitive Dust Risk Management Plan provided on January 8, 2024 was reviewed and comments sent. The annual report is a summary of activities that are required from each of the six risk management implementation plans, including the Communication Plan, Dust Emissions Reduction Plan, Remediation and Reclamation Plan, Worker Dust Protection Plan, Uncertainty Reduction Plan, and Monitoring Plan. Activities that were reported for the Monitoring Plan are completed to provide operational and environmental monitoring data to ensure continued reduction of fugitive metals and dust emissions and to verify the safety of subsistence foods and water as well as the environment in the vicinity of the mine, road and port. |
