EXECUTIVE SUMMARY
Teranis Consulting Ltd. (Teranis) was retained by the Iskut Band Council (IBC) and Indigenous and Northern Affairs Canada (INAC) to conduct a Phase 1 Environmental Site Assessment (ESA) of Kluachon IR 1, Iskut IR 6, and Stikine River IR 7. The objective of the Phase 1 ESA was to establish the environmental condition of Reserve lands and specifically to identify areas of potential or known contamination that may represent a risk or liability to IBC.
The Phase 1 ESA included a review of available historic information, interviews and a site reconnaissance conducted in general accordance with guidance provided by the Canada Mortgage and Housing Corporation (CMHC) Phase 1 Environmental Site Assessment Criteria (CMHC, 1994), Canadian Standards Association (CSA) Standard Z768-01 and Section 58 of the British Columbia Contaminated Sites Regulation (CSR). The site inspection component of the Phase 1 ESA was conducted between June 27, and 30, 2017.
The principle residential community of the Iskut Band is located on Iskut IR 6, which is located on the east side of Hwy 37 approximately 84 km south of Dease Lake, BC. A single residential and/or seasonal use dwelling is located on Stikine River IR 7. No development appears to have been conducted Kluachon Lake IR 1. Existing and/or historic land uses of a commercial or industrial nature appears to have been limited to the Kluachon Centre and Gas Station, which was originally developed as the Co-op Store in the early 1970’s. No commercial or industrial activities were identified on Kluachon IR 1 or Stikine River IR 7.
Historically numerous aboveground and a smaller number of underground fuel storage tanks were located on Iskut IR 6 to supply fuel for electrical generation, heating and/or the gas station. The majority of these tanks have been removed and most buildings are currently heated by propane, electricity and/or fire wood. Fuel storage tanks remaining on Iskut IR 6 include two residential heating oil tanks, a heating oil tank for the Gymnasium/School and gasoline and diesel tanks at the Kluachon Centre.
Land use adjacent to the Iskut reserves typically consists of undeveloped forest and/or large water bodies. A BC Hydro Electrical Generation Station, NorthwesTel telecommunications facility, two (2) rock quarries, airfield and landfill site are located adjacent to Iskut IR 6. None of these adjacent land uses are considering pose a risk to the environmental condition of reserve lands.
Based on the findings of the Phase 1 ESA, Areas of Environmental Concern (AECs), where contamination is known to be present and Areas of Potential Environmental Concern (APEC) were contamination may be present, were identified on Iskut lands as follows:
Areas of Environmental Concern (AECs)
AEC 1 (FCSI 05364002) - Hydrocarbon contaminated soil at the former Co-op Store and Gas station (currently the Kluachon Centre and Store); and
TERANIS CONSULTING LTD. Page i ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
AEC 2 (FCSI 05364001) - Hydrocarbon contaminated soil within the Klappan School and Gymnasium former UST tank nest. Hydrocarbon staining was also observed below the Gymnasium furnace room
Areas of Potential Environmental Concern (APECs)
APEC 1 – Existing and former ASTs, due to spills or leaks during fuel handling and storage. Investigation of Lot 40 (AST-18at the Band Warehouse) should also include an assessment of potential impacts from historic welding and fabrication on the property. Based on site observations, nature of construction and date of installation, further investigation of AST-25, AST-26 and AST-27 is not considered necessary at this time;
APEC 2 – Fuel storage at the former electrical generator sites (i.e. former Co-op Store, Pumphouse and Health Clinic and School circa 1982). Waste oil and anti-freeze was reportedly disposed of at the original health clinic generator building, which was subsequently referenced as the Village Storage Shed (circa 1994);
APEC 3 – Former Public Works Yard on Lot 73, due to fuel storage, drum storage, surface soil staining and possible waste burning (ash residues)
APEC 4 – Auto bodies on the south side of Zetu Creek, historically implemented as an erosion control measure (precise location to be determined);
APEC 5 – Stockpile of contaminated soil previously located on Lots 139 and 140;
APEC 6 – Pesticide and hydrocarbon staining in the crawlspace of a former Nursing Clinic (INAC IEMS report, Federal Site Identifier - 6918) which may include the location of the current “Head Start” or ‘Family Place’ buildings;
APEC 7 – Outhouse pits were reportedly used to burn or bury household waste (circa 1982);
APEC 8 – Water Quality in Zetu Creek from upstream mining and exploration activities;
APEC 9 – Historic mechanics shop and auto repairs on Lot 4 (NRCAN Lot 171);
APEC 10 – Potential historic surficial dump site located on Lots 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 119 and 120;
APEC 11 – Kluachon Store Oil Water Separator soak away pit, due to spills and potential for poor or inadequate maintenance.
APEC 12 – Accumulation of abandoned vehicles on a residential Lot 55 (circa 1994);
APEC 13 – Long term historic use of outhouses and septic systems impacting groundwater and surface water in Zetu Creek and Kluachon Lake;
Additional site investigations will be required to delineate the extent and degree of contamination within the identified AECs and to determine if there are any unacceptable levels of risks to human health and/or ecological receptors. Further investigations will also be required to determine if potential
TERANIS CONSULTING LTD. Page ii ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA) contaminants of concern (PCOC’s) are present within the identified APEC’s at concentrations that exceed applicable assessment criteria.
In addition to further investigation of the previously identified APEC’s and AEC’s, Teranis also recommends the following:
• IBC to contact Pottinger and Gaherty to request a better quality copy of the 2006 FNESS report to more clearly identify the location of AST-8, AST-9;
• Confirm the location of the Nursing Station referenced in INAC IEMS reports (Federal Site Identifier - 6918) and identified as APEC 6;
• Conduct further community interviews with members and elders to determine if and where creosote preserved water pipes may have been used within the community prior to construction of the community water distribution system in the early 1980’s;
• Identify a suitable number of potential candidate sites for further investigation under APEC 7, where former outhouses may have been used to bury and burn household wastes. The focus should be on older residences that were located in Iskut prior to the mid-1980s;
• Inspect homes in Iskut IR 6 with wood burning stoves and determine if asbestos paneling is present as a heat shield as noted in the 1994 Phase II Site Environmental Issues Inventory report, prepared by Norecol, Dames & Moore. Where present, assess the condition of the paneling and remove, repair or replace as necessary; and,
• Analyse a sample of corrugated paper insulation identified on the exterior of a derelict building in the former pre 1960 Iskut village site for asbestos.
It should be noted that the two recommendations regarding asbestos containing materials (ACMs) do not typically represent an environmental lands management issue unless these materials are disposed of inappropriately and therefore may be addressed independently of the FNLMA process. Any materials suspected to contain asbestos will require testing by a suitably qualified contractor to safeguard building occupants and ensure proper disposal prior to building renovation or demolition.
It is recommended that the above information gaps in land use history be addressed prior to completing any further Phase 2 site assessment work. This will ensure that all environmental concerns are identified and encompassed within any future agreements with Canada.
This executive summary has been prepared to provide a general overview of this project, and the reader should not rely on it for any purpose except for which it was prepared. Only the full report should be relied upon for information regarding findings and recommendations.

1.0 INTRODUCTION
1.1 Project Background
The Iskut Band Council (IBC) and Indigenous and Northern Affairs Canada (INAC) retained Teranis Consulting Ltd. (Teranis) to conduct a Phase 1 Environmental Site Assessment (ESA) of IBC reserve lands that fall under the First Nations Land Management Act (FNLMA). These included Kluachon Lake IR 1, Iskut IR 6 and Stikine River IR 7. The locations of the reserves are shown on Figure 1.
Under the FNLMA agreement process, Canada has undertaken to identify the environmental condition of IBC reserve lands prior to the potential ratification of a land code. The first step to identify if contamination may be present on IBC lands is to conduct a Phase 1 Environmental Site Assessment (Phase 1 ESA). The following report documents investigation methodologies and presents the results of the Phase 1 ESA. The site inspection component of the project was conducted between June 27 and 30, 2017.
1.2 Project Objective
The objective of the Phase 1 ESA was to identify past and present land use that may have resulted in contamination of IBC lands and which may require further investigation, remediation and/or risk management in accordance with existing or future contaminated sites regulatory regimes that may be applicable to Iskut lands.
1.3 Scope of Work
The scope of work presented below was based on a proposal (File reference TR17017.01) dated May 12, 2017, prepared by Teranis in response to a request for proposal/statement of work received from INAC on behalf of the IBC on May 10, 2017.
Investigation methodologies used during the environmental assessment were generally based on guidance provided by the Canada Mortgage and Housing Corporation (CMHC) Phase 1 Environmental Site Assessment Criteria (CMHC, 1994), Canadian Standards Association (CSA) Standard Z768-01 and Terms of Reference provided by INAC.
Although procedures adopted for the Phase 1 ESA were similar to those used to conduct a Stage 1 Preliminary Site Assessment (PSI) under Section 58 of the British Columbia Contaminated Sites Regulation (CSR), there was no intent to satisfy Provincial Ministry of Environment (MoE) requirements.
Tasks completed to meet the project objectives, included the following:
. Historic Research and Records Review: This included readily available historic records from IBC, INAC, BC Ministry of Environment (MoE), Environment Canada, Health Canada, Natural
TERANIS CONSULTING LTD. Page 1 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
Resources Canada (NRCAN), Federal Contaminated Sites Inventory (FCSI), National Pollutant Release Inventory (NPRI), Ministry of Energy and Mines, Local Municipality or Regional District, BC Ministry of Highways and Transportation, and aerial photographs.
. Interviews: Interviews were held with band members and elders to obtain relevant information regarding historic land use on and adjacent to IBC lands.
. Site Reconnaissance: A visual inspection of IBC lands and adjacent properties was conducted to establish current site conditions on and adjacent to the reserves. The reconnaissance was used to identify items such as surface staining (oil staining, surface depressions, fill areas), stressed vegetation, evidence of aboveground storage tanks (ASTs) and underground storage tanks (USTs), effluent discharges (air and water), waste management practices, and location of chemical storage areas (i.e., including fuels, oils, preserved wood, herbicides, pesticides, etc.).
. Identification of Concerns: Areas of Potential Environmental Concern (APEC) where contamination was suspected and/or Areas of Environmental Concern (AEC) where contamination was known to exist were identified based on the records review and site inspection.
. Report Preparation: A final report was prepared to compile historic information, document methodologies utilized during the investigation, summarize the results of the investigation and provide recommendations for additional work, as required.
As per the Terms of Reference provided by INAC, the environmental assessment was limited to land within reserve boundaries as shown on the attached figures at the end of this report. Inspections completed by Teranis staff were limited to portions of reserve land that were readily accessible and were either previously or currently developed. Inspections were also focused on areas where historic records and/or where IBC members identified the potential presence of environmental concerns.
Assessment of adjacent land use was based on observations made from reserve land and/or interpretation of historic records reviewed as part of this Phase 1 ESA.
Mr. Daryl Dennis and Mr. David Abou, (representing IBC) accompanied Teranis staff during the site reconnaissance of Kluachon Lake IR 1 and Iskut IR 6 to facilitate access to all areas of the reserves and provided anecdotal information regarding historic land use. Mr. Marty Nole provided a boat to access Stikine River IR 7 and also accompanied Teranis staff during the inspection.
No soil, sediment, surface water or groundwater sampling was carried out during the investigation and no destructive sampling of building envelope(s) was performed to investigate the potential presence of hazardous building materials, such as asbestos or PCBs.

2.0 SITE DESCRIPTION
2.1 General Description
Iskut Band Council (IBC) lands include Kluachon Lake IR 1, Iskut IR 6, and Stikine River IR 7, which are all located in a relatively remote region within northern British Columbia. Kluachon Lake IR 1 and Iskut IR 6 are situated approximately 6 hours’ drive north of Smithers BC, while Stikine River IR 7 is located on the south side of the Stikine River across from Telegraph Creek. Select photographs taken during the site inspection and from historic reports reviewed during the Phase 1 ESA are presented in Appendix A.
Iskut IR 6 is located on the east side of Hwy 37, approximately 80 km south of Dease Lake on the east side of Kluachon Lake. This reserve represents the main village site of the Iskut community (established in 1962), which also includes the Chief Louis Arena, Kluachon Store and Gas Station and adjacent (off-reserve) rock quarry, air strip, BC Hydro Electrical Generating Station and landfill site. The reserve is also bisected by Zetu Creek.
Kluachon Lake 1 is located approximately 300-400 m west of Iskut IR 6 adjacent to the south east corner of Kluachon Lake. Apart from a single residential dwelling no other significant features or land uses were identified on this reserve.
Stikine River IR 7 is located on the south side of the Stikine River approximately 300 m south west of Telegraph Creek. Historically, a single residential building and one or two smaller structures have been located on the reserve. Access to this reserve is limited to travel by boat from Telegraph Creek.
General reserve locations are shown in Figure 1 and site details, including adjacent land use are presented in Figure 2 through Figure 4.
General information for each Reserve is summarized in the following table:

TERANIS CONSULTING LTD. Page 4 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
Item Description
Climate The average daily mean temperature is -0.5°C and the total annual average precipitation is 445.3 mm, 280mm of which falls as rain and 213cm of which falls as snow. Climate information is based on climate data acquired from Environment Canada for the Dease Lake weather station Climate ID 1192340 (see Appendix B for details). Topography Topography on and adjacent to each reserve are shown on Figure 5 and, Figure 6.
Kluachon Lake IR 1 This reserve is relatively flat.
Iskut IR 6 This reserve is relatively flat with a slight slope to the southwest along the eastern boundary of the reserve and steep upland areas located to the north and east. Stikine River IR 7 In general this reserve slopes from the southeast towards the Stikine River in the northwest. The slope transitions from gradual in the southern portion of the reserve to steep along the northern edge of the reserve. Surficial Geology Based on iMapBC1.
Kluachon Lake IR 1 and Hazelton Group – Mesozoic undivided volcanic rocks. Iskut IR 6 Surficial overburden consists of glaciofluvial deposits of sand and gravel. Stikine River IR 7 Stuhini Group – Mesozoic undivided arc volcanic and sedimentary rocks.
Hydrology and Surface Water Bodies Kluachon Lake IR 1 The reserve is bounded by Kluachon Lake to the west and a portion of the Iskut River bisects the southwest corner of the reserve. Iskut IR 6 Zetu Creek bisects the reserve and an additional small unnamed creek runs through the southeastern portion of the reserve. Stikine River IR 7 This reserve is bounded by the Stikine River along its northern edge and a small unnamed creek bisects the reserve running from the southeast corner north towards the Stikine. Hydrogeology and Local groundwater flow is inferred to generally follow local topographic gradients, Groundwater Flow toward local streams, rivers and other nearby water bodies. Direction Groundwater flow may also be influenced by shallow underlying bedrock, confining layers and/or underground utilities, if and where present. Generally groundwater flow direction is inferred as follows: Kluachon Lake IR 1 South to southwest toward the adjacent lake and following the direction of flow in the Iskut River. Iskut IR 6 Southwest towards Kluachon Lake and the Iskut River and locally toward Zetu Creek Stikine River IR 7 North towards the Stikine River.

Item Description
Kluachon Lake IR 1 No floodplain mapping was identified for this location.
Iskut IR 6 No floodplain mapping was identified for this location.
Stikine River IR 7 No floodplain mapping was identified for this location.
Contaminant migration from one property to another is most likely to occur via groundwater transport. Windborne deposition, physical relocation of contaminated soil and/or vapour migration also represent additional mechanisms (generally to a lesser degree) by which contaminated media may migrate from one site to another. Consequently, a property is generally at greatest risk from upgradient sources rather than those properties located cross gradient (perpendicular) or downgradient to the site (subject to influence by underground utilities, underlying bedrock slope etc.).
In order to identify if adjacent land use or historic events have the potential to influence conditions on the subject property, only those properties that are located within 300 m of the reserve boundaries are considered further (as per, BC Technical Guidance Document #10, Appendix 12). Site specific conditions, such as the presence of surface water bodies (typically representing a barrier to groundwater migration), are also taken into consideration. Other factors taken into account include:
• The size and nature of the source (i.e. residential, commercial or industrial scale);
• The potential presence of dense non-aqueous phase liquids. These contaminants are not constrained vertically by the presence of a water table and can migrate against the apparent or inferred groundwater table following underlying geological stratigraphy;
• Depth to groundwater and sub-surface soil permeability; and,
• Utilities, which may act as subsurface interceptor trenches (i.e. barriers) or facilitate contaminant migration rate and re-direction.
Generally, and subject to a review of various site specific conditions (such as those noted above), non- industrial sources of contamination located more than 200 m upgradient, 100 m cross-gradient or 50 m downgradient of the applicable reserve boundaries are not considered to pose a substantial risk.
The relative coarse nature of the sands and gravels that are likely to be encountered on and surrounding the reserves, suggest that the potential for migration of contaminants in the dissolved phase (if and where present) would be relatively high.
Based on anticipated groundwater flow direction and site specific conditions, adjacent land use that has the greatest potential to impact the environmental conditions of reserve lands is as follows:
Kluachon Lake IR 1 – Land use to the north, and east.
Iskut IR 6 – Land use to the north and east.

Stikine River IR 7 – Land use to the south.
The above factors have been considered when assessing the likelihood of off-site land use affecting reserve lands, if and where applicable.

3.0 REGULATORY CONTEXT
There are no specific regulatory requirements for conducting a Phase 1 ESA on Federal land, only guidance, as outlined in Section 1.3 of this report. Within the Provincial domain site investigations must be conducted in accordance with the requirements of the Contaminated Sites Regulation, particularly if a statutory instrument, such as a Determination or Certificate of Compliance (CoC), is required.
Environmental acts, regulations and guidelines that are applicable on reserve land, include, but are not limited to, the following:
• Canadian Environmental Protection Act (CEPA);
• Fishers Act;
• Species at Risk Act (SARA);
• Transportation of Dangerous Goods Act (TDGA);
• Indian Reserve Waste Disposal Regulations;
• Canadian Council of Ministers of the Environment (CCME) Canadian Environmental Quality Guidelines (CEQG);
• CCME Canada Wide Standards for Petroleum Hydrocarbons (PHC) in Soil (PHC CWS);
• Health Canada (HC) Canadian Drinking Water Guidelines; and,
• FCSAP Federal Interim Groundwater Quality guidelines.
It should be noted that the Federal Interim Groundwater Quality Guidelines are intended to be used as assessment and remediation criteria for Federal contaminated sites funded by the Federal Contaminated Sites Action Plan (FCSAP). The Federal Groundwater Quality Guidelines represent interim guidelines only and should not be used once CCME Canadian Groundwater Quality Guidelines become available.
Provincial legislation associated with the management of contaminated land that may be applicable in the absence of Federal guidance or may be required to assess disposal options for contaminated material during future remediation or risk management; include the following:
• Environmental Management Act (EMA);
• Contaminated Sites Regulation (CSR);
• Hazardous Waste Regulation (HWR);
• British Columbia Approved Water Quality Guidelines (BCAWQG); and,
• British Columbia Working Water Quality Guidelines (BCWWQG).
TERANIS CONSULTING LTD. Page 8 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
Both Federal guidelines and Provincial standards provide assessment criteria based on the nature of land use, i.e. agricultural, parkland, residential, commercial or industrial, and water use, i.e. freshwater and/or marine/estuarine. Consequently applicable community land use plans should be referenced to identify which guidelines or standards should be adopted to assess future investigation findings (if required). In the absence of suitable land use plans, IBC may wish to adopt a conservative approach and use residential land use criteria as a precautionary measure to protect existing and future changes in land use.
In addition to the nature of land use, the selection of applicable Federal and/or Provincial soil and groundwater standards or guidelines is also influenced by a number of site-specific factors, such as, use and distance of groundwater and surface water on or downgradient of the area under investigation. The following standards or guidelines may be applicable on IBC lands; dependent on specific site conditions encountered at the investigation site and/or based on future land use requirements:
Soil Assessment
• Soil ingestion (CWS, CEQG and CSR);
• Soil where groundwater may be used as drinking water (CWS, CEQG and CSR);
• Ecological protection and toxicity to soil invertebrates and plants (CWS CEQG and CSR);
• Soil where groundwater may be used as drinking water (CWS CEQG and CSR);
• Soil where groundwater may impact freshwater aquatic life (CWS, CEQG and CSR);
• Soil where groundwater may be used for irrigation and/or livestock watering (CWS and CSR);
• Soil disposal with BC (HWR).
Groundwater Assessment
• Groundwater that discharges to a surface water body used by aquatic life (CSR and FCSAP GWQG);
• Groundwater used for irrigation or livestock watering (CSR and FCSAP GWQG);
• Groundwater used as drinking water (CSR and HC);
• No Water Use standards (CSR).
Surface Water Assessment
• Surface water for freshwater aquatic life (including CEQG, BCAWQG and BCWWQG).

Soil vapour Assessment
Health Canada and FCSAP have produced a document entitled “Federal Contaminated Site Risk Assessment in Canada, Part VII: Guidance for Soil Vapour Intrusion Assessment at Contaminated Sites", which provides risk assessment guidance specific to vapour intrusion exposure pathway.
The BC CSR also specifies methodologies for conducting site investigations and soil vapour assessment in the presence of ‘detectable’ concentrations of volatile organic compounds (CSR - Schedule 11).

Based on the historic air photograph review, potential environmental concerns identified on IBC lands are summarized as follows:
Reserve(s) Summary of Potential Concerns
Kluachon Lake IR 1 Potential for other wastes to be deposited with woody debris.
Iskut IR 6 Potential for residential heating oil tanks.
Gas Station/Store. Possible fill material deposited on the north side of Zetu Creek. Potential for other waste to be deposited with woody debris.
Stikine River IR 7 None identified
The cooling system (salt water, glycols or ammonia) was not considered to represent a risk to the reserve based on the age of the arena.
It should be recognized that the ability to assess conditions on or surrounding IBC land is dependent on, and limited to, the resolution of the air photographs.
4.4 Historic Title Search
The reserves currently fall under Federal jurisdiction, consequently it was not considered necessary to conduct an historic land title search.
4.5 BC Ministry of Environment (MoE) Records
4.5.1 Groundwater Well Records
One (1) groundwater well was identified between Kluachon Lake IR 1 and Iskut IR 6. The well is owned by BC Hydro and is classified as a water supply well. No other relevant information was present in the detailed well record. The detailed well record is presented in Appendix B and the location of the well is displayed on Figure 7.
It should be noted that Provincial well inventories are typically incomplete and additional wells may be present. Based on other source of information reviewed during the Phase 1 ESA, additional former and existing wells are located east of the reserve boundary (i.e. off-reserve) on the north side and adjacent to Zetu Creek. The existing wells supply water to a large storage tank located on a bluff overlooking the east side of the reserve.
No groundwater wells were identified on or adjacent to Stikine River IR 7.

4.5.2 Site Registry
Two (2) large area searches (10 km x 10 km) were conducted using the Ministry of Environment (MoE) Online Site Registry database to identify Provincial Environmental Records on or adjacent to IBC reserve lands. The center of each search area was located as follows:
• Kluachon Lake IR 1 and Iskut IR 6 - 57° 50’ 6.82” N and 129° 59’ 29.8” W
• Stikine River IR 7 – 57° 53’ 37.6” N and 131° 10’ 41.9” W
The Site Registry search identified one (1) registered site located in the vicinity of Iskut IR 6 and three (3) registered sites were identified in the search area centered on Stikine River IR 7. A detailed search of the site registry indicates that the registered site located adjacent to Iskut IR 6 is the Eddontenajon Diesel Generating Station owned and operated by BC Hydro. All three (3) registered sites in the area centered on Stikine River IR 7 were associated with Telegraph Creek located across the Stikine River from the reserve.
Properties listed under the Site Registry are not generally considered to pose a risk to reserve land if they are located upgradient by more than 200 m, cross gradient by more than 100 m, downgradient by more than 50m (based on known or inferred groundwater flow direction) and/or are separated by lakes, rivers or streams.
Based on their locations, inferred groundwater flow direction and/or intervening water courses, none of the sites identified by the Site Registry search are considered to pose a risk to the environmental condition of reserve lands.
The locations of the registered sites area displayed on Figure 7 and Figure 8. Copies of the BC Online search are also presented in Appendix B.
4.5.3 Ecological Catalogue (EcoCat)
A search of the BC MoE Ecological Reports Catalogue (EcoCat) website identified the following EcoCat records located within 1.5 km of IBC reserve lands:

4.6 First Nations Health Authority (FNHA) Records
A request was made to Mr. Neil Nabata (FNHA, Northern Region) regarding records for the Iskut reserves and communities. At the time of issuing this report, a response had not been received from the FNHA. However, should pertinent information be provided by Health Canada, an addendum will be issued to disclose this information to IBC.
A copy of the email request with FNHA is included in Appendix B.
4.7 Environment Canada Records
Based on previous correspondence with Ms. Cindy Grenkie (Administrative Services Assistant with Environment Canada), Environmental Enforcement no longer provides historic documentation or reports for First Nation reserves.
4.8 National Pollutant Release Inventory (NPRI)
Review of the National Pollutant Release Inventory (NPRI) identified two (2) NPRI facilities within 5 km of IBC lands.
NPRI Facility Name Approx. Distance Summary of On-Site Releases ID from Site 7805 British Columbia Approx. 120m Carbon monoxide in air (0.246 tonnes – 2015) Hydro and Power (Iskut IR 6) Nitrogen oxides in air (1.1 tonnes – 2015) Authority – Particulate Matter (PM10) in air (0.016 tonnes – 2015) Eddontenajon Diesel Particulate Matter (PM2.5) in air (0.015 tonnes - Generating Station 2015) 7806 British Columbia Approx. 1.03 km Carbon Monoxide in air (7.8 tonnes - 2015) Hydro and Power (Stikine River IR 7) Nitrogen oxides in air (34 tonnes - 2015) Authority - Telegraph Particulate Matter (PM10) in air (0.507 tonnes - 2015) Creek Diesel Particulate Matter (PM2.5) in air (0.489 tonnes - Generating Station 2015)

Summary of Potential Environmental Concerns from INAC Reports
Areas of potential environmental concern identified from historic reports provided by INAC are summarised for each reserve as follows:
Reserve Summary of Potential Concerns
Iskut IR 6 1. Former electrical generators (with suspect fuel storage tanks) were identified at the former Pumphouse, clinic and School and Co-op Store; 2. Former Heating oil AST at the Klappan Day School;
3. Historic outhouse pits were used to burn and burry garbage (1982) 4. Former heating oil ASTs were located at the two (2) former Teacherages (1985); 5. A former heating oil AST was noted at the former Old School and Kindergarten in 1985 (possibly one of the former Teacherages); 6. A former gasoline tank was identified at unknown location in an area with satellite dishes and used to store cement mixers in 1989. Possibly Band Equipment Storage area or Public works Yard.

Reserve Summary of Potential Concerns
7. Hydrocarbon contaminated soil is located at a depth of 2.2 in the former UST tank nest at the Klappan Independent School. Contaminated soil was also identified within the crawlspace below the boiler room. 8. Hydrocarbon contaminated soil is located at a depth of 4.6m-bgs at the east end of former UST-2 tank nest west of the former Co-op Service station.
9. Numerous fuel storage tanks and hydrocarbon stained soils were identified within the Public works Yard. 10.Abandoned residential heating oil tanks in the Public works Yard, indicate that heating oil tanks were previously located within the adjacent community prior to 2006; 11.Waste oil and antifreeze was reported to have been “dumped” at the former Village Storage shed in 1994. It is suspected, but not confirmed that the former storage shed represents the former generator shed located immediately east of the original Health Clinic. 12.Automobile bodies were reportedly used to minimize erosion within Zetu Creek;
13.Hydrocarbon contaminated soil was stockpiled at the south end of the rhubarb subdivision on Lots 139 and 140 in 2001. Subsequent soil testing in 2005 indicated that soil quality met applicable criteria. No details regarding the number and locations of samples collected were provided.
4.10 IMES and FCSI Reports

Note: Estimated 25 cubic meters of material
05364005 Iskut IR 6 Active Initial testing completed. Detailed testing underway. PHCs and PAHs in soil. Note: Estimated 6,000 cubic meters of material.
It should be noted that the Federal FCSI site is based on regional information and is often not up to date with current information managed by the BC Region under the IEMS system. The IEMS is continually updated and more accurately reflects current site conditions and the status of site investigation and/or remediation work.
Based on IEMS data and information provided by INAC, there are a number of errors and a duplication of information on the FCSI database. It should also be noted that the estimated 6,000 m3 of impacted soils is an arbitrary value used as a placeholder and does not accurately reflect site conditions.
Except for the site already identified under the Integrated Environmental Management System (IEMS) no additional contaminated sites were identified under FCSI and no records were identified for any of the other reserves involved in this investigation.
Summary of Potential Environmental Concerns from IEMS Reports
Areas of potential environmental concern identified from the IEMS review are summarised for each reserve as follows:
Reserve Summary of Potential Concerns
Iskut IR 6 Contaminated soils remain at the Kluachon Centre Store/Fuel Station, which have not been delineated.
Soil staining was noted at the Maintenance Yard. Pesticide use and possible fuel storage or leaks at the Nursing Station. Klappan School/Community Hall, additional site assessment and/or remediation required. Derelict vehicles were located within the community.
Copies of the IEMS and FCSI search results are presented in Appendix B.
4.11 Iskut First Nation Records
No reports were available for review at the time of issuing this report.
TERANIS CONSULTING LTD. Page 27 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
4.12 BC Ministry of Transportation and Infrastructure (MoT)
The Chief Environmental Officer of BC Ministry of Transportation and Infrastructure (BC MoT), indicated that the BC MoT does not maintain records of environmental incidents, such as fuel or chemical spills, that may have occurred on roads or highways located on or adjacent to reserve lands.
4.13 Province of British Columbia – Spills & Environmental Emergencies
A review of the Province of British Columbia – Spills & Environmental Emergencies Spill Incidents and Past Spill Incidents3 reports were reviewed. No current or past spill incidents were reported for areas in the vicinity of the reserves under investigation.
4.14 Natural Resources Canada (NRCAN)
Maps and Reserve boundaries were identified using maps presented on the NRCAN web site. The accuracy of the maps has not been confirmed.
Members of the Iskut Band and Tahltan Bands expressed surprise and concern that the location of Stikine River IR 7, as identified by NRCAN, does not coincide with the location of the former Iskut village site located on the south side of the Stikine river, immediately south of Telegraph Creek.
4.15 Fire Insurance Maps
Buildinghistory.ca was contacted to determine if any fire insurance maps were present for buildings on and adjacent to the reserves under investigation. No fire insurance maps were identified.
4.16 Ministry of Mines and Energy Records
A search of the Ministry of Energy and Mines MINFILE database4 and Historic Mines Atlas5 identified no existing or historic mines within 500 m of the reserves. The closest Historic mine sites to Iskut IR 6 were the Mabon and Kitty mines located approximately 2.6 km southeast and 4.5 km north east, respectively. The closest mine site to Stikine River IR 7, was a placer mine located at Buck Bar approximately 4.5 km west of the reserve.
The locations of the historic mine sites are shown on Figure 9.
4.17 Sanitary and Storm Water Discharges
Information provided by Dan Todd P.Eng. of Urbans systems, is summarized as follows:
There are no community sanitary sewer systems on any of the reserves. Houses and buildings within Iskut IR 6 have individual septic tanks and leaching fields.

TERANIS CONSULTING LTD. Page 28 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
Storm water is conveyed via roadside ditches and culverts. Soils with Iskut IR 6 are highly permeable and therefore storm water infiltrates into the ground very quickly, without discharging to any surface water bodies located downstream of the system.
No storm water infrastructure was identified on any of the reserves.
4.18 Site Services and Utilities
Information provided by Dan Todd P.Eng. of Urbans systems, is summarized as follows:
Drinking water is provided by two drilled wells. The water is treated using ultraviolet light and chlorine, however, the chlorine treatment system is not currently in operation. Community members report that apparent water quality is good. The treated water is pumped to a storage reservoir located on a bluff east of the reserve before gravity distribution to the community. The distribution system provides domestic water and fire protection to the community.
Hydro is supplied by overhead lines and all associated infrastructure, including transformers, are owned and operated by BC Hydro. Based on the age of the BC Hydro infrastructure (early to mid- 1970’s, it is considered unlikely that electrical equipment will contain polychlorinated biphenyls (PCBs).
4.19 Waste Disposal
Historic records indicate that residential wastes were picked up on a weekly basis in the early 1970’s. However, it was also reported that there was no formal waste pick up in the 1990’s and that community members had to take their own wastes to the Regional District of Kitimat-Stikine (RDKS) landfill site located north of Iskut IR 6.
Currently household wastes are picked up on a weekly basis and transported off-reserve to the landfill site. Septic tanks are pumped out every 2-5 years based on demand and waste solids are also disposed of to the RDKS landfill septic pit.
4.20 Nature and History of Adjacent Land Use
The nature and history of adjacent land use was compiled from a review of historic records, such as air photographs, and information provided during interviews. Land use located adjacent to each of the reserves, is summarised in the following table:

Historic bulk fuel storage and pesticide use at the BC Hydro Generating Station represents a potential source of contamination on adjacent properties. However, based on distance and inferred groundwater flow direction, this site is unlikely to have adversely impacted either Kluachon Lake IR 1 or Iskut IR 6. Similarly, based on distance, historic fuel storage at the air field and waste disposal at the Regional District landfill site is unlikely to pose a risk to Iskut lands.
Adjacent land use is shown on the figures attached at the end of this report.

5.0 SUMMARY OF INTERVIEWS & COMMUNITY MEETING
A PowerPoint presentation was made to the community on Jun 28, 2017, to outline the purpose of the Phase 1 ESA and to facilitate gathering of information regarding current and historic development and land use on Iskut Lands. The Community presentation contained numerous photographic examples of potential environmental issues commonly encountered on First Nation lands to encourage participation and stimulate information sharing during the presentation. Participants were also encouraged to identify any other environmental issues of concern.
Relevant information that may represent a potential environmental concern on or immediately adjacent to reserve lands that was obtained during the community presentation and subsequent informal interviews and discussions during the site inspections, is summarised as follows:
• A heating oil tank was locate adjacent to the original band office located within the old village site on the south side of the creek, in the vicinity of Lots 53 and 56 (APEC 1).
• A fuel tank may have been located at the Band Warehouse site on Lot 39 (NRCAN Lot 200), east and adjacent to the current band office. Information provided at a subsequent community meeting noted that this information was incorrect and the tank was most likely located on Lot 40 (APEC 1);
• A fuel storage tank associated with an electrical generating station was previously located on the road side of the original pump house, adjacent to Zetu Creek (APEC 2);
• Contaminated soil from the former Co-op was deposited at the south end of the Rhubarb subdivision on the west side. The soil may have been moved to another location (APEC 5);
• Members confirmed that waste materials were often burned on residential lots during periods without formal and regular garbage pick within the community (APEC 7);
• Ongoing mineral exploration to the east of Iskut IR 6 was identified as a concern, particularly with respect to impacts to water quality within Zetu Creek (APEC 8);
• Lot 4 (NRCAN Lot 173) has been used as a mechanic/automotive repair shop (APEC 9);
• Waste materials have been unearthed in shallow soils in the vicinity of Lots 111, 112, 113, 119A, 119B and 120. This area of the reserve was suspected of being a possible dump site (APEC 10).
• Leaching of contaminants into Zetu Creek and Kluachon Lake from all the historic outhouses and septic systems (APEC 13);
A second community meeting was held in Iskut on July 24, 2017, to present and validate the draft Phase 1 ESA findings. These meeting also provided an opportunity to add additional information to the final Phase 1 ESA report that may not have been identified during the previous meeting or subsequent site inspection. Pertinent information gathered during the final community meetings is summarized as follows:
• Heating oil tanks were previously located on Lots 15 and 16 (APEC 1);
TERANIS CONSULTING LTD. Page 31 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
• A heating oil tank were previously located adjacent to a former Band Administration building located immediately north of Lot 56 (APEC 1);
• A heating oil tank was previously located adjacent to the former store located west of the former Band Administration building and north of Lot 55 (APEC 1);
• No heating oil tank was previously located on Lot 39 (NRCAN Lot 200) as noted during the initial community meeting. The Band Warehouse on this lot is a relatively new building. A former tank may have been used at the older Warehouse located on Lot 40 (NRCAN Lot 201), which is now supplied with propane. This building has also been used as a welding and metal fabrication shop (APEC 1);
• A former gasoline tank, depicted in a photograph in the 1989 Village Maintenance Plan, prepared by Chatwin Engineering, was located in the former Public Works Yard, adjacent to one of the two buildings located on the south side of the Yard (APEC 1);
• Morris Louie was identified as a potential source of information regarding how fuel was stored at the former pump house generator site (i.e. AST or UST). Mr. Louis subsequently reported that fuel for the generator was stored in an above ground tank on the road side of the building (APEC 2).
• The former Co-op diesel/electric generator and fuel tank was reported to be located approximately 20-30 m north of the centerline the new Kluachon Centre building and approximately 20-30 m east of the south east corner of the fenced Kluachon AST compound (APEC 2);
• The use of auto bodies to reduce bank erosion rates on Zetu Creek was confirmed, primarily on the south side of the channel. Donny McPhee was noted as most likely to know the locations in which the vehicles were buried. However, Mr. McPhee did not recall the precise locations the vehicles were buried and thought that they may be buried near the new bridge (APEC 4);
• Contaminated soil from the Co-op and Klappan School underground tank decommissioning program was placed on Lot 139 and 140. The soil was reportedly tested, verified to be clean and subsequently removed. However, visible soil mounds remain on the two lots, and Chief and Council suspect the soil was not removed (APEC 5);
• The former health or nursing clinic referenced under Federal Site Identifier – 6918 may represent the original health clinic, which was replaced by a new building and is currently occupied by “Head Start”, located north of Lot 160. The former clinic may also represent a former clinic now called the “Family Place” located north of Lot 159 and south of the new Health Clinic (APEC 6);
• Waste materials previously reported to have been deposited on the east side of the Kluachon subdivision in the area of Lots 111, 112, 113, 119 and 120 may also include the eastern portions of Lots 102 to 106 and the northern portions of Lots 107, 108, 109 and 110 (APEC 10); and,
• A residential lot, where derelict vehicles were noted to have accumulated in a 2006 FNESS report, was identified as Lot 55 (APEC 12);

General Information
Additional general information provided by community members that is was not associated with a specific environmental concern on reserve lands, included the following:
• IBC have no previous environmental reports to be included in the Phase 1 ESA report;
• While there have been a few derelict vehicles on Iskut IR 6, no one could recollect accumulations of more than 5 vehicles on any one property;
• Although a number of wood cabins were previously located on Kluachon Lake IR 1, no permanent structures or residences have been constructed on the reserve. The open area on Kluachon Lake IR1 at the west end of the gravel road was reported used to store and cut up logs for firewood;
• A small dump was reported at the south end of the air field (the south end of the airfield slopes steeply down toward Zetu Creek and is covered with dense vegetation and the presence of the dump site could not be confirmed during the site inspection. If present the dump site would be located off-reserve;
• No rail lines, pipelines or hydro corridors cross or have crossed any of the reserves;
• No hydro or telephone poles have been stored on Iskut IR 6;
• The septic system on Lot 60 was hand built by the owner and does not appear to be working properly. Strong sewage odours are present within and adjacent to the building;
• The BC Hydro Generating station was established in the mid-1970’s;
• A number of abandoned buildings are located on the reserve, which are perceived as a potential health risk due to the presence of rats;
• A small lake located off reserve several kilometers north of Iskut IR 6 (across from the Mountain shadow resort) is called Drum Lake due to the presence of large numbers of 205 L drums in the lake. The location of Drum Lake could not be identified during the site inspection;
• Community members were puzzled why Stikine River IR 7 does not appear to encompass the historic Iskut village site on the south side of the Stikine River. The reserve identified by NRCAN appears to be located approximately 900 m west of the former village site; and,
• Heating in the former Iskut Village site located east of the Stikine River reserve was by wood only.
• A fuel tank may be located on Donny McPhee’s property, i.e. Lot 103 (subsequent information provided by IBC indicates that previous fuel storage on this property was limited to two (2) small tidy tanks which are now empty);
• A portion of the original water distribution system was reportedly constructed with banded wood-stave pipe that may have been preserved with creosote. Attendees expressed concern that elevated incidences of “blood cancer” in the community may be associated with the old piping;
• No spills have occurred from road traffic accidents on or adjacent to Iskut lands;

6.0 SITE RECONNAISSANCE
Mr. Ian Collings (Teranis) conducted the site reconnaissance of Kluachon Lake IR 1 and Iskut IR 6 on June 28th, 2017 and was accompanied by Mr. Daryl Dennis and Mr. David Abou, representing IBC. Mr. Marty Nole accompanied Mr. Collings during the inspection of Stikine River IR 7 and the former Iskut village site located approximately 1 km east of the reserve.
6.1 Summary of Site Observations and Conditions
The following table represents a summary of site observations and/or site conditions that may represent potential environmental concerns on IBC lands or may be relevant during future investigations.
Summary of Site Observations/Conditions
Septic Systems All residential dwellings and community buildings are serviced by septic tanks and fields.
Drinking Water Drinking water is supplied from two (2) wells located off-reserve, east of the reserve boundary, adjacent and north of Zetu Creek. No drinking water systems were identified on the other reserves.
Indications of previous No indications of previous environmental investigations, such as groundwater Environmental monitoring wells were identified on reserve lands. Four (4) groundwater Investigations and/or monitoring wells were observed on the east and north sides of the fenced BC Remediation. Hydro Generator Station. The presence of groundwater monitoring wells at this location is consistent with the findings of the historic record review, which indicate the generator site is listed on the BC site registry.
BC Hydro has been contacted for further information regarding the nature of environmental impacts at the Generator Station, however no information has been received at the current time [to be updated as required]
USTs and ASTs No underground storage tanks (USTs) were identified during the site inspection.
The following aboveground storage tanks (ASTs) were identified on Iskut IR 6 during the site inspection.
• A single doubled walled and vacuum monitored, Envirosafe AST (approximately 9,100L heating oil) located at the north end of the Gymnasium (installed 2001);
• Two (2) double walled and vacuum monitored ASTs (50,000 L gasoline and 9,000 L diesel) located on the north side of the Kluachon Centre Store, both installed in 1999;
• A single 2,000 L heating oil tank located on the south side of the residence on Lot 5 (NRCAN Lot 172).
• A single 1,100 L heating oil tank located on the south side of the residence
TERANIS CONSULTING LTD. Page 34 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
Summary of Site Observations/Conditions
on Lot 6 (NRCAN Lot 173;
All the ASTs appeared to be in satisfactory condition with no surface soil staining at any of the AST locations.
Evidence of a former AST or UST was observed in the form of a copper fuel line that was identified on the south side of a brown colour wooded building, located east of the original clinic. The wooden shed was the reported location of the former clinic generator shed and was likely supplied with diesel from an AST or less likely a UST.
What appeared to be a plastic “vent pipe” was observed on the north side of the former Pumphouse located on the south east portion of Lot 188. Fuel was reportedly stored at this site for an electrical generator; however, the material used for the “vent pipe” is not typical of a UST (information subsequently provided by a community member indicated that fuel for the former electrical generator at this location was stored in an above ground tank).
Oil/Water Separators An oil/water separator (OWS) was identified immediately west of the fenced compound containing the above ground fuel storage tanks for the Kluachon Centre Store. The OWS services both the refueling pad and the pump island pad. Based on INAC records, the OWS appears to be connected to a sub-surface soak away pit located 5 m west of the northwest corner of the fenced tank compound.
Sumps, Pits and No sumps, pits or lagoons, except septic tanks and former outhouse pits, were Lagoons identified or reported on any of the reserves.
Surface Staining, Spills Surface soil staining was noted at the following locations: and/or Stressed • Former Band Works Yard Vegetation • Below the furnace room in the Gymnasium
• A small area of staining was observed below a residential heating oil tank located on the south side of the BC Hydro Generating Station (located off- reserve).
No visual evidence of hydrocarbon staining was identified on either Kluachon Lake IR 1 or Stikine River IR 7.
Hazardous Materials, No accumulation or bulk storage of hazardous materials or liquids, other than bulk Waste Management or fuel storage in the above noted ASTs, were identified on any of the reserves. Waste Burning No dump sites were observed on Iskut IR 6, although community members report that waste materials have been uncovered during digging of surficial soils in the vicinity of Lots 111 to 120, on the east side of the community.
Household wastes are picked up from the communities in Iskut on a weekly basis and are transported off-reserve to the adjacent RDKS landfill site located approximately 1 km north of the reserve.
A small dump site containing waste metal and two (2) heavily corroded 205 L steel

Summary of Site Observations/Conditions
drums were noted at the bottom of a slope, north of former residences and farm buildings located toward the west end of the former pre 1960’s Iskut Village site, situated approximately 900 m east of Stikine River IR 7. Based on distance and inferred groundwater flow direction this waste disposal site is unlikely to pose a risk to the Stikine River IR7 reserve.
Lot 120 on Iskut IR6 and a central area within Kluachon Lake IR 1 are used to store and cut firewood by community members. Small quantities of surficial wood wastes were observed at this site.
General housekeeping within Iskut IR 6 was found to be good, with little or no significant accumulations of waste materials or derelict vehicles. As noted during the community meeting a number of derelict or abandoned log homes are located in the oldest part of the community.
Ash deposits in the area of the former Band Works Yard suggest that waste burning has occurred in this area of the community on Iskut IR 6.
Waste Water No waste water treatment systems apart from septic tanks and fields were Treatment identified during the site inspection.
Fill Material No evidence of imported fill material was observed on any of the reserves.
Methane Potential anthropogenic sources of methane, such as buried waste (i.e. landfill sites) or buried wood waste were not identified on any of the reserves.
Asbestos Containing The majority of buildings on IBC lands were constructed after the early to mid- Materials (ACM) 1970’s and/or have been renovated since this period. Consequently these buildings are unlikely to contain friable forms of asbestos. Asbestos containing materials such as vinyl and tile flooring materials and cement board may be present in some of the older buildings, however, most have probably been removed during renovation or refurbishment and therefore the likelihood of finding large quantities of ACM is considered to be low.
Corrugated paper insulation observed on the exterior wall of a derelict building located at the site of the former Iskut village, approximately 900 m east of Stikine River IR 7 may contain chrysotile asbestos.
Note; although inspections were not conducted within residences, historic documentation indicates that asbestos paneling may be associated with wood burning stoves within residential dwellings in Iskut IR 6.
Asbestos surveys should be completed prior to renovation, demolition or disposal of any building, particularly those constructed prior to the early 1980’s, so that ACM’s may be identified and removed in accordance with applicable regulations prior to being disturbed. If vermiculite insulation is identified in any of the building attics, this material should be tested for asbestos content prior to any disturbance.
Asbestos containing materials (ACM’s) within buildings are unlikely to adversely

Summary of Site Observations/Conditions
impact the environmental condition of IBC land unless demolition materials have been buried on reserve. No evidence of this practice was reported or identified during the Phase 1 ESA.
Polychlorinated No PCB containing equipment was identified or reported on any of the Reserves. Biphenyls (PCBs) Electrical transformers located within the communities are owned and operated by BC Hydro. Based on the age of the hydro infrastructure, i.e. post 1970’s, it is unlikely that transformers contain PCB dielectric fluids.
Fluorescent lamp ballast within older building that pre-date the 1980’s may contain PCBs. These electrical fittings are unlikely to adversely impact the environmental condition of IBC lands. Where present, PCB lamp ballasts should be segregated for appropriate disposal in accordance with applicable federal guidance.
Chlorofluorocarbons No obvious large scale sources of CFCs were identified. Small scale use of CFCs (CFCs) will include air conditioners, refrigerators, coolers and vehicle air conditioning systems.
Urea Formaldehyde No evidence of UFFI was observed within the buildings and no injection holes were Foam Insulation (UFFI) observed in exterior building envelopes.
Lead and Mercury While the quantity of lead in paint was limited by regulation to less than 0.5% by weight in 1976 and to less than 0.06% in the early 90’s, lead may still be present in some paints, particularly older exterior paints. Small quantities of lead may also be encountered as solder on electrical equipment and domestic water pipes.
Although no obvious sources of mercury were identified or reported on the Reserves, small quantities may be present in electrical equipment and thermostats.
Small quantities of lead and mercury may be associated with building demolition materials in dump sites, where present.
Radioactive Materials No obvious sources of radioactive materials were observed or reported on any of the reserves. Smoke detectors within buildings may contain small quantities of radioisotopes.
Pesticides, Herbicides, No large-scale or widespread use of pesticides (including herbicides and wood Fungicides, Wood preservatives) were identified on any of the reserves. Preservatives Pesticides may have been used for weed suppression within the BC hydro Generating Station located off-reserve across Hwy 37. If present these chemicals are unlikely to have impacted either Kluachon Lake IR 1 or Iskut IR 6.
Noxious & Invasive No noxious or invasive weeds were identified or reported during the site Weeds inspection.
Mining and Acid No mining related activities or mining related sources of acid generating rocks Generating Rocks were identified on or immediately adjacent (i.e. within 500 m) any of the reserves.

Fuel storage tanks and environmental monitoring wells were identified at the BC Hydro Facility. It is also likely that pesticides are used to supress vegetation growth within the fenced compound. Large air vents on the contained used at the NorthwesTel facility suggest that the building may contain a backup electrical generator with a diesel tank. However, based on distance and inferred groundwater flow direction, none of the adjacent land uses are considered to pose a potential concern with regards to the environmental condition of reserve lands.

7.0 SUMMARY OF FINDINGS & POTENTIAL ENVIRONMENTAL CONCERNS
Iskut lands encompassed by the Phase 1 ESA include Kluachon Lake IR 1, Iskut IR 6 and Stikine River IR 7. The main residential community is located on Iskut IR 6, which is located on the east side of Hwy 37, approximately 80 km south of Dease Lake. This reserve represents the main village site of the Iskut community (established in 1962) and includes the Chief Louis Arena, Kluachon Store and Gas Station and adjacent (off-reserve) rock quarry, air strip, BC Hydro Electrical Generating Station and landfill site.
Kluachon Lake 1 is located approximately 300-400 m west of Iskut IR 6 adjacent to the south east corner of Kluachon Lake. Stikine River IR 7 is located on the south side of the Stikine River approximately 300 m south west of Telegraph Creek. Apart from single derelict residential dwelling on Stikine River IR 7, no land use or development has occurred on either reserve. Access to Stikine River IR 7 is by boat only, from Telegraph Creek.
Existing and/or historic land uses of a commercial or industrial nature on Iskut lands appears to have been limited to the Kluachon Centre Store and Gas Station located on the west side of Iskut IR 6, adjacent to Hwy 37. This site was originally developed as the Co-op Store and gas station in the early 1970’s.
Information obtained from historic records, site observations and community meetings indicate that former and existing ASTs located on Iskut IR 6, include the following:

AST-25 Kluachon Centre Store 50,000 In-use Double walled, vacuum monitored gasoline tank located in a fenced compound with spill containment system installed in 1999. AST-26 Kluachon Centre Store 9,000 In-use Double walled, vacuum monitored diesel tank located in a fenced compound with spill containment system installed in 1999. AST-27 North end of the 9,100L In-use Double walled, vacuum Gymnasium monitored, heating oil tank installed in 2001.
Based on information contained within a 2006 FNESS report, it appears that at least two (2) residential heating oil tanks were located within the Iskut community at unknown locations. To facilitate identification of previous AST locations, select photographs from historic reports (where available) have been included in Appendix A.
No ASTs or USTs were identified on Kluachon Lake IR 1 or Stikine River IR 7. Previous USTs associated with the former Co-op Store and Service Station and the gymnasium and school have been removed and replaced with AST’s. No evidence of heating oil AST or UST was identified at the Church.
Land use adjacent to the Iskut reserves typically consists of undeveloped forest and/or large water bodies. A BC Hydro Electrical Generation Station, NorthwesTel telecommunications facility, two (2) rock quarries, airfield and landfill site are located adjacent to Iskut IR 6. However, considering inferred ground water flow direction and/or distance from the reserve boundary, they are considered unlikely to have adversely impacted the environmental condition of reserve lands.
During the final community meeting, the potential presence of wood stave water pipes was identified as a concern, specifically due to the potential risk that the water pipes may have been preserved with creosote. Mr. Dan Todd (Community Infrastructure Engineer with Urban Systems) indicated that wood stave pipes were more typically used in the early 1900’s and he was not aware of any stave pipes being used in the 1960’s when the community was first established. Based on available records the community water system was constructed between 1980 and 1992 and the water mains were all constructed from PVC. It is possible that some wood stave pipe may have been used before the community system was built, however this type of piping would not have been connected to the community system when it was built.
Based on the findings of the Phase 1 ESA, Areas of Environmental Concern (AECs), where contamination is known to be present and Areas of Potential Environmental Concern (APEC) were contamination may be present, were identified on Iskut lands as follows:
TERANIS CONSULTING LTD. Page 41 ISKUT BAND COUNCIL PHASE 1 ENVIRONMENTAL SITE ASSESSMENT (ESA)
September 2017
Areas of Environmental Concern (AEC)
The Phase I ESA identified two (2) Areas of Environmental Concern (AECs). These areas have been previously identified and acknowledged by INAC and are at various stages of investigation within the 10 Step Process described in the Federal Contaminated Sites Action Plan (FCSAP).
AEC 1 (FCSI 05364002) – A relatively small volume of hydrocarbon contaminated soil (~13m3) remains in the area of the former tank nest at a depth of ~4 m at the former Co-op Store and Gas Station (currently the Kluachon Centre and Store). Additional excavation and confirmatory sampling was recommended. The former Co-cop site is depicted as follows:
1994 photograph of the former Co-op Gas Station, Sketch from a 2007 PGL report, showing the former with pump island and tank nest in the foreground. Co-op tank nest and remaining hydrocarbon impacts.
AEC 2 (FCSI 05364001) - Hydrocarbon contaminated soil remains within the former UST tank nest located adjacent to the Klappan School Gymnasium. Hydrocarbon staining was also observed below the Gymnasium furnace room. A screening level human health risk assessment was recommended. The former Klappan School tank site is depicted as follows:
2017 photograph of the former Klappan School fuel Sketch from a 2007 PGL report, showing the former tank site, on the east side of the gymnasium. Klappan School tank nest and remaining hydrocarbon impacts.
Step #3 (initial Testing), Step 4 (NCSCS Classification) of the FCSAP 10 Step Process have been completed for each of the AECs and recommendations for further investigation and/or remediation have been included in the applicable environmental reports.

September 2017
Areas of Potential Environmental Concern (APECs)
APEC 1 – Existing and former ASTs, due to spills or leaks during fuel handling and storage. Investigation of Lot 40 (AST-18 at the Band Warehouse) should also include an assessment of potential impacts from historic welding and fabrication on the property. Based on site observations, nature of construction and date of installation, further investigation of AST-25 AST- 26 and AST-27 (see previous table) is not considered necessary at this time (see Photographs 4, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 21, 24, 25, 27, 28, 29 and 36);
APEC 2 – Fuel storage at former electrical generator sites at the former Co-op Store, Pumphouse and Health Clinic and School circa 1982 (see Photographs 6, 23, 30 and 32). Waste oil and anti- freeze was also reportedly disposed of at the original health clinic generator building, which was subsequently referenced as the Village Storage Shed (circa 1994);
APEC 3 – Former Public Works Yard on Lot 73, due to fuel storage in numerous above ground storage tanks, drum storage, surface soil staining and waste burning (Photographs 7, 8, 10, 11, 13, 14, 34 and 35),
APEC 4 – Auto bodies on the south side of Zetu Creek, historically implemented as an erosion control measure (precise location to be determined);
APEC 5 –Stockpile of contaminated soil located on Lots 139 and 140 (Photograph 34);
APEC 6 – Pesticide and hydrocarbon staining in the crawlspace of a former Nursing Clinic (INAC IEMS report, Federal Site Identifier - 6918) which may include the location of the current “Head Start” or ‘Family Place’ buildings (Photograph 33);
APEC 7 – Outhouse pits were reportedly used to burn or bury household waste (circa 1982);
APEC 8 – Water Quality in Zetu Creek from upstream mining and exploration activities;
APEC 9 – Historic mechanics shop and auto repairs on Lot 4 (NRCAN Lot 171);
APEC 10 – Potential historic surficial dump site located on Lots 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 119 and 120;
APEC 11 – Kluachon Centre Oil Water Separator soak away pit, due to spills and potential for poor or inadequate maintenance (Photograph 36).
APEC 12 – Accumulation of abandoned vehicles on a residential Lot 55, as referenced in the 2006 report prepared for FNESS by Pottinger Gaherty Environmental Consultants (Photograph 33);
APEC 13 – Long term historic use of outhouses and septic systems impacting groundwater and surface water in Zetu Creek and Kluachon Lake;
AEC and APEC locations are shown on Figure 10, Figure 11 and Figure 12.
A summary table including APEC and AEC details and, associated PCOC and recommendations for further investigation is presented in Appendix D.

8.0 RECOMMENDATIONS
As noted previously, a number of AEC’s and APEC’s were identified on Iskut lands. Additional site investigations will be required within the identified AECs to delineate the extent and degree of contamination and to determine if there are any unacceptable levels of risks to human health and/or ecological receptors. Further investigations will also be required to determine if potential contaminants of concern (PCOC’s) are present within the identified APEC’s at concentrations that exceed applicable assessment criteria.
In addition to further investigation of the previously identified AEC’s and APEC’s, Teranis also recommends the following:
• IBC to request that Pottinger and Gaherty provide a better quality copy of the 2006 FNESS report to more clearly identify the location of AST-8, AST-9;
• Confirm the location of the Nursing Station referenced in INAC IEMS reports (Federal Site Identifier - 6918) and identified as APEC 6;
• Conduct further community interviews with members and elders to determine if and where creosote preserved water pipes may have been used within the community prior to construction of the community water distribution system in the early 1980’s;
• Identify a suitable number of potential candidate sites for further investigation under APEC 7, where former outhouses may have been used to bury and burn household wastes. The focus should be on older residences that were located in Iskut prior to the mid-1980s;
• Inspect homes in Iskut IR 6 with wood burning stoves and determine if asbestos paneling is present as a heat shield as noted in the 1994 Phase II Site Environmental Issues Inventory report, prepared by Norecol, Dames & Moore. Where present, assess the condition of the paneling and remove, repair or replace as necessary; and,
• Analyse a sample of corrugated paper insulation identified on the exterior of a derelict building in the former pre 1960 Iskut village site for asbestos.
It should be noted that the two recommendations regarding asbestos containing materials (ACMs) do not typically represent an environmental lands management issue unless these materials are disposed of inappropriately on Iskut lands and should be address independently of the FNLMA process. Any materials suspected to contain asbestos will require testing by a suitably qualified contractor to safeguard building occupants and ensure proper disposal prior to building renovation or demolition.
It is recommended that the above information gaps in land use history be addressed prior to completing any further Phase 2 site assessment work. This will ensure that all environmental concerns are identified and encompassed within any future agreements with Canada.

Dear Neil,
Teranis Consulting has been retained by the Iskut First Nation and Indigenous and Northern Affairs Canada (INAC) to carry out a Phase 1 Environmental Site Assessment (ESA) of the following Iskut lands:
• Kluachon Lake IR 1 • Iskut IR 6 • Stikine River IR 7
The purpose of the Phase 1 ESA is to assess current and historic land use on or adjacent to reserve lands and to identify locations that are known or suspected to be contaminated. The Phase 1 ESA involves a review of available historic records, interviews with community members, and a site inspection.
As part of this process, I would be grateful if you could review your files to determine if you have any information for the Iskut lands noted above that would be relevant to our assessment. We are interested in any of the following types of information:
• Drinking water quality; • Water waste disposal; • Solid waste disposal (including dump site and landfills); • Environmental contaminants; • Records of spills or releases; • Fuel or hazardous material storage or disposal; • Records of environmental inspections or reports; and, • Ambient or indoor air quality concerns.
Please feel free to add any other information you believe would be appropriate to include in our report.
We greatly appreciate any assistance you can provide. Should you have any questions with the above request or require any additional information please do not hesitate to contact myself or Ian Collings at the undersigned.

Station / Element Metadata
Statistics listed below are provided as a guide to determine the validity of Normals and Extremes calculations. For example, a station with 30 years of record between 1981 and 2010 with no missing years would be a more reliable normal than a station with 15 years of record and 2 missing years. Less than 100% possible observations indicates that out of the total number of observations used, some records were missing.

Nursing Stations, like this site, were supposedly dealt with under Health Canada. We don't have any record of what has happened, other than the following Action Tracking note from IEMS: Site Reconnaissance and Limited Soil Sampling (Golder, 2008): no indications of surface petroleum hydrocarbon contamination were observed at the Iskut Nursing Station and no fuel storage tanks were present. Although pesticides (bromocide) had been used in the crawlspaces. Recommended that care be taken with the application of rodent control measures. A water leak was observed in the crawlspace of the old nursing station building. If not yet addressed, 903329007 6918 Iskut (08363) - IR6 Nursing Station it is recommended that the leak be repaired immediately and moisture extracted from NA NA the crawlspace. Immediate action is also warranted to address the presence of mould associated with the water leak. It is also recommended that the Band management apply appropriate measures to prevent inadvertent access to the crawl space and stored materials. Health Canada funding work at site. No funds required from INAC. FNESS consultant recommends: site reconnaissance; collection of surficial soil samples (pesticide contamination); collection of soil and/or vapour samples (hydrocarbons); preliminary assessment of human health; and development of recomendations should contamination be identified.

* Represents likelihood of contamination in environmental media, rather than risk to human or ecological receptors.
** In situations where hydrocarbon impacts appear to be limited to surficial soil over a relatively small area, such as less than 5 m2, it may be more cost effective to excavate and set aside the obviously impacted material and then collect a stockpile soil sample and confirmatory samples. Soils will need to set aside at a pre-agreed location and placed on top of and below polyethylene sheeting. A mechanism to provide timely approval or pre-approval and funding for this optional activity will be required.
** Based on field observations and findings, additional test pits/boreholes/monitoring wells may be required to assess soil, groundwater and/or soil vapour quality.

* Represents likelihood of contamination in environmental media, rather than risk to human or ecological receptors.
** In situations where hydrocarbon impacts appear to be limited to surficial soil over a relatively small area, such as less than 5 m2, it may be more cost effective to excavate and set aside the obviously impacted material and then collect a stockpile soil sample and confirmatory samples. Soils will need to set aside at a pre-agreed location and placed on top of and below polyethylene sheeting. A mechanism to provide timely approval or pre-approval and funding for this optional activity will be required.
** Based on field observations and findings, additional test pits/boreholes/monitoring wells may be required to assess soil, groundwater and/or soil vapour quality.
