3 Page 2 This report presents the results of a study, onduted under the terms of the Inuvialuit Final Agreement, to determine the supply of granular materials and the 20-year demand for granular materials in the ommunity of Inuvik. Development senarios and reommendations designed to optimize the utilization of resoufes for the antiipated demand are presented. n II. In summary, the 20-year demand for granular materials in the ommunity is nearly 7.6 million ubi metres. Ninety-eight perent of the demand is for projets of a speulative nature, suh as onstrution of the Inuvik-Tuktoyaktuk highway andprodution of armour stone for large- sale offshore petroleum prodution failities. The remainder of the demand is for loal apital projets (70,200 ubi metns) and maintenane of ommunity failities (107,000 ubi metres). Granular materials suffiient to meet the foreast demand are available in the Inuvik area. Rok, rok produts and general fa are available on a year -round basis by all-weather roads; higher quality aggregates must be obtained at distant soures during the winter months. Certain bedrok soures have ready aess to waterways, haeasing their attrativeness for utilization in offshore projets. Inuvik is a mature ommunity that has been meeting its granular resoure requirements adequately for many years. It is reommended that the ommunity ontinue to obtain and manage its granular resoures the in manner it has established. II 3

6 Page 5 1.O INTRODUCI'ION I 1.1 Baknl.ound II The Inuvialuit Final Agreement provided that Canada grant to the Inuvialuit, fee simple title to a land quantum of 90,650 square kilometres (35,000 square miles) in the Western Arti Region. The Agreement further speified that the land be sub-divided into two ategories, that with mineral rights and that without. For purposes of lassifiation, the two ategories have beome known as 7(l)(a) and 7(l)(b) lands, respetively. The former inludes 12,950 square kilometres (5,000 square miles) of lands; the latter 77,700 square kilometms (30,000 square miles). The 7(l)(a) lands are generally loated adjaent to eah of the six ommunities (Aklavik, Holman, Inuvik, Paulatuk, Sahs Harbour and Tuktoyaktuk, Figure 1) onsidered in the Final Agreement. The 7(l)(b) lands generally surround the l)(a) 7( lands and extend outward fiom the ommunities. The Agreement reognized that most of the proven granular resoures of aeptable quality within reasonable distane of the ommunities were loated on Inuvialuit l)(a) 7( lands. In order to ens= that adequate reserves of granular material were maintained at a regulated ost, the Agreement granted ontrol of the 7( l)(a) granular resoures to the Inuvialuit, subjet to enain provisions. For purposes of the projet desribed in this report, the provisions onern the supply of, and the demand for, granular resoures. Under the terms of the provisions, the Inuvialuit agreed to maintain granular material reserves of appropriate quality suffiient to meet the projeted 20-year demand as determined by the Inuvialuit Land and appropriate levels of government. The demand for granular materials was to be formed on the basis of estimates of requirements in eah ommunity. rr In order to ensure that adequate supplies of sand and gravel of appropriate quality remained available within reasonable distane of the ommunities, the provisions stipulated that the supply of granular materials should be priorized aording to end use as determined by the 20-year demand. The first priority was established as the need of the ommunity, the seond priority is the need of the Inuvialuit and the third priority is the need of others. Indian and Northern Affairs Canada mac], on behalf of the ILA, has undertaken to develop a granular resoures inventory and management plan to fulfill these initial

9 Page EVALUATION OF GRANULARRESOURCES General n k m A standard for the lassifiation of granular borrow material does not exist within the study area. The first granular resoure inventories in the region, arried out in the early 1970s, lassified potential borrow material enountered during exploration aording to the Unified Classifiation System [USC]. However, this general lassifiation proved inadequate beause there was no diret referene to the end use of the material. Several years ago, the Government of the Northwest Territories [GNWT] initiated a lassifiation system whereby potential granular borrow was graded aording to its most suitable appliation. The territorial government's system provided the following five material groups: Conrete Aggregate [CAI, Surfaing Material [SMJ, Base PI, Subbase [SB], Ehbankment [E] and Rip-Rap. In 1983, INAC adopted a lassifiation system similar to that presented in the draft Territorial Pits and Quarries Regulations that onsidered both the USC lassifiation of the material as well as the most suitable end use. This system, modified by INAC, is the basis for all borrow material lassifiation arried out under the urrent ontrat. Materials at prospetive borrow soures have been graded into one of the five following lasses: Class 1 Exellent Quality Material, Class 2 Good Quality Material, Class 3 Fair Quality Material, Class 4 Poor Quality Material and Class 5 Bedrok, Felsenmeer and Talus. These abbreviated desriptions are elaborated upon in the following subsetions of this report.

10 Page 8 Exellent quality material onsisting of lean, well-graded, struturally-sound sands and gravels suitable for use as high quality surfaing materials, or as Class 2 asphalt or onrete aggregate, with minimum a of proessing. Good quality material generally onsisting of well-graded sands and gravels with limited quantities of silt. This material will provide good quality base and surfae ourse aggregates or struture-supporting fa. Prodution of onrete aggregate may be possible with extensive proessing, exept where deleterious materials are present Class 3 Fair quality material onsisting generally of poorly-graded sands and gravels with or without substantial silt ontent. This material will provide fair quality Class 4 general fill for roads, foundation pads laydown or yards. Poor quality material generally onsisting of silty, poorly-graded, fine-grained sand with minor gravel. These deposits may also ontain weak partiles and deleterious materials. These materials are onsidered suitable for marginal general (non-strutural) fill Class 5 Bedrok of fair to good quality, felsenmeer or talus. Potentially exellent soures of onstrution material, ranging from general to onrete fill aggregate or building stone if quarried and proessed. Also inludes erosion ontrol materials suh as rip-rap or armour stone Summary The five material lasses presented above are summarized in Table 1.For referene purposes, the GNWTs lassifiation system has been orrelated in the table with the adopted INAC system.

12 Page 9 I 2.2 Inventory n The alulated volumes of the various types of granular materials available at the examined soures have been divided into various ertainty levels, as detailed below. These definitions are onsistent with those used by WAC Proven A 'proven' volume is one whose ourrene, distribution, thikness and quality is supported by ground truth information suh as geotehnial drilling, test pitting and/or exposed stratigraphi setions. Usually the thikness of material enountered in a borehole is extrapolated to a radius not exeeding 50 metres around the hole Probable A 'probable' volume is one whose existene and extent is inferred on the basis of diret and indjret evidene, inluding topography, landform harateristis, airphoto interpretation, extrapolation of stratigraphy, geophysial data and/or limited sampling FVospetive A 'prospetive' volume is one whose existene is suspeted on the basis of Limited diret evidene, suh as airphoto interpretation and/or general geologial onsiderations. In the ontext of this projet, the unertainty assoiated with prospetive volumes of granular material varies with the terrain onditions speifi to the various ommunities. For instane, substantial amounts of bedrok are loated northwest of the ommunity of Aklavik. Sine the bedrok has not been explored in detail, the volume of rok is onsidered to be prospetive. Any exploration would likely result in the prospetive volume beoming 'probable' or 'proven'. The situation is very different in the viinity of Tuktoyaktuk, where granular materials are sare and landforms are poorly defined. Features that ontain 'prospetive' volumes of material are often found during detailed investigation to ontain little or no useable granular material.

13 Page 3.0 SUPPLY OF GRANULAR RESOURCES The amount of information available on the borrow soures in the viinity of eah ommunity varies greatly. This is due in part to the histori level of ativity in and around eah ommunity, but predominately to the relative supply of aeptable quality borrow within reasonable distane of the ommunity. Communities whose growth has not been signifiantly affeted by northern petroleum exploration (ie. Holman, Paulatuk and Sahs Harbour) have little formal information regarding the loation, size and quality of appropriate borrow soures. As the granular materials demand in general is modest and wholly generated by the ommunity, there is little inentive to undertake borrow material studies provided adequate quantities for urrent needs exist adjaent to the ommunity. The quality of the borrow materials may not meet desirable standards but this usually offset by the onvenient loation. If the borrow performs poorly one in plae, is it a simple matter to obtain more material and improve the deteriorating mas. Communities whose reent growth an be partially attributed to northern petroleum exploration (Inuvik and Tuktoyaktuk) have greater requirements for granular resoures. These requirements usually impat both the quality and quantity of borrow materials. Industrial developments usually require large volumes of higher quality material. The extent of identifiation and investigation of granular material soures has depended upon loal demand. Minimal information is available pertaining to borrow reserves in the viinity of Holman, Paulatuk and Sahs Harbour. Transport Canada has onduted airphoto studies for the area adjaent to eah ommunity, but the results have not been onfirmed by field evaluations. Information pertaining to borrow resoures for Inuvik and Aklavik is available, however, extensive exploration work has not been undertaken beause developed soures have been suffiient to meet the demands. Tuktoyaktuk is a unique situation with respet to supply of granular materials Although Tuktoyaktuk has grown substantially over the past 10 years and petroleum resoure ativities have put unusual demands on granular material resoures, semi-ontinuous granular resoure exploration ativities have generally failed to prove large deposits of quality material within a reasonable distane of the ommunity.

14 Page 11 The supply of granular resoures for the six western Arti ommunities was determined summarizing existing data from site investigations, airphoto interpretation and field reonnaissane of prospetive soures. These estimates were made by ombining the areal extent of the soures (aerial photography and field measurements) with the stratigraphy determined fiom test pits and boreholes within the soure. The auray of the estimates may not aurately reflet the true situation as detail is laking for ertain soures. Some soures have no ground truthing or very few boreholes and test pits and the depth to whih the investigations were ompleted was often insuffiient to reasonably represent the extent of the individual materials within a soure. Testing of samples for moisture ontent or grain size analysis was not neessarily arried out onsistently and so designation of a ertain lass of material to a partiular soure may be based only upon visual soil desription. Soure-by-soure desriptions and estimated material volumes are loated in the Supply appendix. The following setions desribe the supply of granular resoures situated on or near 7( l)(a) and 7( l)(b) lands adjaent to the ommunity of Tuktoyaktuk General Inuvik is loated at the base of the Caribou Hills at the eastern margin of the Makenzie Delta, Granular materials available within the the delta are loated on Rihards Island, loated 80 km NNW of Inuvik. Surfiial sediments in the delta are omposed of Quaternary fluvial, deltai and estuarine sediments omprising lay, silt and sand. Coarser glaial sediment overlies the fluvial deposits loated on the southern portion of the island Inuvik's high quality granular material requirement is frequently met with Class 2 material from the YaYa ILake pit loated on the southern part of Rihards Island fiom and the western flank of the Caribou Hills. The CaribouHillsonsist of poorlyinduratedonglomerates,quartziti sandstones and mudstones, exept in the viinity of Inuvik, where the hills are omposed of shales. A terrae remnant loated on the western flank of the Hills supplies muh of Inuvik's requirement for good quality fill.

15 Page 12 The Roky Hills, loated 15 km SSE of Inuvik, omprise sandstones and dolomites. Several quarries are established in this area where rushed rok is produed as onstrution material where higher quality granular resoures are required. A desription of the granular resoures loated within the ommunity's region is presented in the following setions Class 1 L C Figure 4 shows that a relatively small portion of the available granular resoures in the Inuvik area are Class 1 materials. Only Soure 303 is onsidered to have any Class 1 material and the potential volume is 1,OOO,OOO ubi metres (Table 7). Soure 303 is loated approximately 82 km NNW of Inuvik on the shore of the Makenzie River and environmental onstraints along with diffiult aess may limit the viability of this soure as a primary soure of Class 1 material Class 2 II There is a signifiant volume of Class 2 material within the general Inuvik region (Figure 4). The total probable volume is estimated at 29,146,000 ubi metres and the prospetive volume is 53,846,000 ubi metres. The largest single soure of Class 2 material is Soure 326 with approximately 5,000,000 ubi metres of probable and up to 17,800,000 ubi metres of prospetive volume. Inuvik urrently obtains a substantial portion of the required Class 2 material from Soure I407 )Kenaston Pit), loated 61 km NW of the ommunity.. This soure has a probable volume of 4,600,000 ubi metres and a prospetive volume of 15,000,000 ubi metres. Other soures with substantial volumes within 7(l)(a) lands inlude 302, 303, 323A, 324a and YaYa Lake. Soure 302 has approximately 1,140,000 ubi metres of probable volume: Soure 303 has 530,000 ubi metres, Soure 323A has 2,500,000 ubi metres and Soure 324A has 1,500,000 ubi metres (Table 8). Following extensive exploration, YaYa Lake was predited to ontain a volume of 8,800,000 ubi metres. However, extensive extration has ourred from YaYa Lake, thus the estimates are not urrent. All of the soures ited here are a minimum of 50 km distane from Inuvik and aess must be by tundrdie road in winter or barge in summer. Two of the soures (323 and 324A) are

A very small soure, 215, is available within the 7(l)(b) lands approximately 100 km north of Inuvik, but the probable volume of Class 2 material is only about 23,000 ubi metres thus development of thus soure is probably not eonomi Class 3 The volume of prospetive Class 3 material is the largest of all materials available in the Inuvik region. Figure 4 shows that nearly 155, ubi metres may be realized. There is nearly 32,000,000 probable ubi metres. Fiftteen of the twenty-eight soures onsidered in the Inuvik region have a supply of probable and prospetive Class 3 material (Table 9). The largest single soure of prospetive Class 3 material within the Inuvik 7(l)(a) lands is Soure 324A with nearly 46,000,000 ubi metres. Up to 1,500,000 ubi metres ould be extrated annually from this soure, yielding a soure life of nearly thirty years. Probable volumes are in the order of 10,000,000 ubi metres. Soure 324A, loated 61 km NW of Inuvik is however, within a proposed IBP area. No proven resoures have been determined this at soure. The next largest prospetive soure is Soure 323A, also within a proposed IBP area, with a volume of 43,510,000 ubi metres. Probable volumes of Class 3 material are approximately 9,000,000 ubi metres. Major volume soures in ordeer of desending size after these two are: 326,303,222, and 317.

The prospetive total is approximately 36,000,000 ubi metres (Figure 4). There are no proven soures of Class 4 material in the region. The largest single soure of Class 4 material in the region is Soure 322 with a total prospetive volume of 9,600,000 ubi metres (Table 10). Soure 322 is loated within 7(l)(a) land approximately 55 km NW of Inuvik and within a proposed IBP area.

22 Page DEMAND FOR GRANULAR RESOURCES 4.1 The purpose of the demand model was to determine the requirements for granular materials within the study area for a period enompassing the next 20 years. The needs of the model required that a substantial amount of speifi information be obtained. This information onsisted of desriptions of proposed types of projets and end users of the granular material, as well as material type and volume requirements. The first step in ompilation of the demand model was the identifiation of individuals and groups likely to have granular material demands or, alternatively, be onerned with the use of granular materials in general. A list of potential respondents was prepared by identifying the various departments in all levels of government involved with ivil- oriented ommunity projets and by forming list a of ontrators residing or prominent in eah ommunity. A questionnaire was then assembled and distributed. The questionnaire was designed to determine the need for various quantities of seleted types of granular materials and to indiate the end use of the material. The questionnaire reipient was also asked to indiate, if possible, the likely or preferred soure of the granular materials for eah projet or material type. In an attempt to quantify the rate of granular material demand, information was requested to bloks, eah five years in length. be submitted in four data Shortly after submission of the questionnaires, two EBA representatives, Messrs. D. Hayley, P. Eng., and J. Carss, P. Eng., visited eah projet ommunity, as well as Yellowknife and Cambridge Bay, to meet with reipients of the questionnaires and other representatives of the loal ommunity to disuss their speifi requirements for granular materials. This not only provided diret ontat with most of the users and regulators of granular materials but also permitted the EBA representatives to beome familiar with loal onditions regarding granular resoures. Reipients of the questionnaire who were not visited were ontated by telephone, where possible, to ensure that all possible input was obtained and to larify any questions or ambiguities that developed regarding the information sought by the questionnaire. The data olleted was then assembled into a omputerized data base to failitate data handling and interpretation.

23 Page 16 A large number of respondents defined material quality in terms other than those in the INAC lassifiation system that was outlined in the questionnaire. Table 1 presents the urrent interpretation of these various lasses of required materials in light of INAC the lassifiation system. The proess of data assimilation indiated that a projet requiring granular materials ould best be desribed as belonging to one of three ategories: planned apital projets, speulative projets and maintenane. While the demand generated by all three projet ategories may be somewhat speulative, the 'speulative' projets ategory speifially refers to large sale projets that may or may not our within next the 20 years. These projets usually involve a politial deision and require a substantial ommitment of both funding and granular materials and typially involve projets suh as airstrips, lengthy highways and onstrution infrastruture of for the prodution of oil and gas. The total demand for granular materials in all of the Western Arti ommunities is graphially presented in Figure 8. The total demand for granular materials the for years 1987 to 2007 has been estimated at 17.4 million ubi metres. Ninety-two perent of the demand (16 million ubi metres) is for projets that have been desribed as speulative, five perent of the demand (0.8 million ubi metres) has been indiated for planned apital projets and three perent of the demand (0.6 million ubi metres) has been designated for maintenane. Most of the demand is reated by the various levels of government, with expansion of private industry requiring only three perent of the nonspeulative apital projet demand. LI Despite the attempt of the questionnaire to determine the 20-year demand in 5-year bloks, most data reeived did not ontain any speifi 5-year information for nonspeulative apital projets beyond The reasons this for ourrene appear to be two-fold: first, the Territorial Government uses an annually up-dated 5-year plan for budgeting apital expenditures; and seond, most of the ommunities will aquire their basi failities (ie. shools, nursing stations, government offies, et.) within the next five years. n n Projets designated as speulative appear to require 38 perent of the designated 16 million ubi metres within the next five years and 62 perent thereafter.

The following subsetions present and disuss the demand data olleted. Granular material requirements for the projets identified within the area of the ommunity are presented and summarized in the Demand appendix. Figures presenting the required volume of eah lass of material for Inuvik are ontained in the following text. 4.2 buvk General Inuvik's 20- year granular material demand onsists of 70,200 ubi metres for loal apital projets, 107,000 ubi metres for maintenane and 7,400,000 ubi metres for speulative projets onsisting of a proposed expansion of Esso's tank farm, the Inuvik portion of the proposed Inuvik-Tuktoyaktuk highway and prodution of rip-rap for offshore prodution failities. All of the apital projets demand is required within the next five years, with most of the material required for publi projets. A demand of only ten ubi metres has been identified for individual use, while private orporate use will require 1683 ubi metres. A summary of material demand by material lass inluding speulative projets is presented in Figure 13; a umulative summary of demand is ontained in Figure 14. Figures 15 and 16 present the same information, exluding speulative projets, respetively. North Star Servie and Constrution Ltd., one of the areas largest ontrators, has identified an immediate 5-year demand of 55,000 ubi metres, based on their familiarity with the ommunity. A substantial portion of this material would be for smau publi apital and maintenane projets; only a small amount would be for individual and private orporate use. Inuvik is the only rate-based ommunity investigated in this study. Beause of this distintion, the ivi govemment has a muh greater responsibility in the planning of loal projets. From the survey it is apparent that the mature state of Inuvik and the present eonomi limate ombine to reate a relatively low overall demand for granular materials. Speulative ventures suh as the Inuvik- Tuktoyalrtuk highway and the Makenzie Valley Pipeline play a very important role in the growth of the ommunity. If onstrution of a pipeline were to be

30 Page 18 initiated planners have projeted that Inuvik's population ould inrease by an order of magnitude to about 25,000. This sudden ommunity growth would reate an extraordinary demand for granular materials that has not been aounted for in this study. Constrution of the Inuvik-Tuktoyaktuk highway would not reate a substantial demand through ommunity growth, but would reate a substantial demabd through the requirements road for fii and surfaing materials. The initiation of either projet ould be the impetus that would stimulate more demand by the ommuntiy for projets not identified in the survey Class 1 Inuvik has generated a demand for 150 ubi metres of Class 1 material for the years between 1987 and 1991, inlusive. There have been no indiated requirements for any Class 1 material beyond Class 2 The Class 2 granular material requirement is 1,960,000 ubi metres. This demand is split disproportionately between eah of the four time periods, with a demand of 5775 ubi metres in the first five years, 1,7 million ubi metres in the seond five years and 100,000 ubi metres in eah of the last five year bloks. Demands over the last 15 years of the study period (1992 through 2006) are reated by the proposed Tuktoyaktuk -1nuvik highway and therefore are onsidered speulative Class 3 Requirements for Class 3 material are 65,280 ubi metres for the years 1987 through 1991, with eah of the the subsequent 5-year bloks requiring 20,750 ubi metres. The bulk of this demand is for material to be used for road maintenane and other general publi projets Class 4 Only 2,000 ubi metres of Class 4 granular material are required durin the first five years of the study period, with no apparent requirement for material of this

31 Page 19 typeinthesubsequentyearsunderstudy. The demandisgenerated by landsaping ativities at Chuk Park Class 5 Slightly more than 5.5 million ubi metres of Class 5 material are required over the next 20 years. For the period 1987 to 1991, the demand is 2,818,153 ubi metres; from 1992 to 1996, 8,000 ubi metres; from 1997 to 2001, 908,000 ubi metres and from 2002 through 2007,1,808,000 ubi metres. Most of the indiated demand is speulative in nature, with the demand for Class 5 material only 42,153 ubi metres, exluding the speulative projets. The proposed Inuvik-Tuktoyaktuk highway would be responsible for generating a demandof 2.8 millionubimetresbetween 1987 and Erosion protetionmaterial for proposed oil and gass prodution failities loated in the Beaufort Sea aounts for a further 2.7 million ubi metres of Class 5 material.

32 Page 20 5.O DEVELOPMENT SCENARIOS 5.1 Inuvik- S e i v e P r o i e m General A substantial portion of Inuviks granular material is urrently obtained from the Boot Lake pit, whih is loated on the southeast edge of the town. The material from this pit is only of fair quality, as it an otain substantail amounts of fiies (silt and lay), but has been used for onstrution of a large part of the town. Also used during town onstrution was shale from a pit loated several kilomews southeast of the ommunity; however, this material us of very poor quality and is no longer onsidered usen. High quality granular material is available from two quarries loated south of Inuvik. Currently in use are tthe Campbell Lake and Transport Canada quarries, whih serve loal and airstrip demands, respetively. Several other prospetive quarry sites are present, but previous demands have not justified further development. The granular resoure development senario propsed for Inuvik, onsidering all speulative projets ia summarized in Table 24 and disussed in the following setions Class 1 Inuvik has expressed only minimal demand for Class 1 granular material. The demand may be satisfied adequately by better setions of the YaYa Lake pit, the prominentsupply of Class 2 materialintheinuvikarea.alternatively, proessed Class 5 material from Soure I403 (Campbell Lake Quarry) may be suitable for meeting the expressed requirement. LI Class 2 The demand for Class 2 material in Inuvik proper is modest, ours only over the first five years of the study period, and an adequately be provided for by the YaYa Lake soure or by Soure Demands for Class 2 material in subsequent years are generated by a speulative projet, the Inuvik -Tuktoyaktuk highway. Between 1992 and 1996,1.7-dion ubi metres of Class 2 granular

33 Page 21 resoure will be required for the portion of the highway extending from Tnuvik to the viinity of the Eskimo Lakes. There are limited reserves of all materials exept Class 5 material in the Inuvik region and it is reommended that this rather substantial volume of material be aquired in the viinity of Eskimo Lakes, speifially fiom Soures 312 and 314. This represents a long haul distane but no signifiant soures of Class 2 material our between the Lakes and Inuvik. Granular material requirements of the highway following onstrution are more modest, but will probably need to be obtained from 312 and 314 as well Class 3 Class 3 requirements are moderate, given the size of Inuvik. Speulative projets do not impose any additional demands to those expressed for loal projets. Unfortunately Inuvik does not have any adjaent soures of Class 3 material. The losest pit is 1407, loated 61 km down-river from the town, with an alternative being the YaYa Lake development. Either of these soures should be able to adequately supply Inuvik's needs. The hoie pit should be a funtion of the quantity to be hauled at a given time and the size of the operation extrating borrow Class 4 Inuvik has indiated a requirement for only 2,000 ubi metres of Class 4 granular material. It is reommended that this volume and any other low quality fill required, be obtained from t Soure 1400, the Boot Lake pit. This soure has been onsidered depleted for several years but the town still manages to obtain material from it. Given the small demand for material of this type, I400 should ontinue in its role as the prominent soure of Class 4 material in the area. Efforts should be made to 'lean-up' and reontour the pit during reovery of borrow in the future sine the pit will eventually be abandoned Class5 Substantial demand for Class 5 material exists both in the short and long term. Volumes required for loal projets are modest ompared to the volumes demanded by the speulative projets. These projets, onsisting of onstrution of the proposed Inuvik -Tuktoyaktuk highway and prodution of material for

34 Page 22 erosion protetion projets assoiated with proposed offshore petroleum prodution failities, require 2.8 and 2.7 million ubi metres of Class 5 material, respetively. The most prominent soure of Class 5 borrow in the viinity of Inuvik is the R28/29, bedrok exposure, loated 20 km south of Inuvik and it is reommended that this soure be developed as the major supply of borrow for large projets. Alternatively, large sale development ould also our at the DPW pit loated 25 kilometres southeast of Inuvik and Soure The seletion of the most appropriate alternative should be made on the basis of eonomis, available volume and material quality. Loal requirements, onsisting of town-related small apital projets and maintenane projets and airstrip maintenane, should ontinue be to supplied from Soure I403 (Campbell Lake Quarry) and Soure I402 (the Transport Canada Quarry), respetively. 5.2 Inuvik- Speulative Pro General A substantial portion of Inuviks granular material is urrently obtained from the Boot Lake pit, whih is loated on the southeast edge of the town. The material from this pit is only of fair quality, as it an otain substantail amounts of fiies (silt and lay), but has been used for onstrution of a large part of the town.

39 Page BORROW SOURCE DEVELOPMENT RECOMMENDATIONS e 6.1 Gened I The following setions present guidelines management plan. and reommendations for developing a These reommendations have taken into onsideration information presented in the Environmental Guidelines: Pits and Quarries Handbook (Indian and Northern Affairs Canada, 1983), and the draft Territorial Lands and Publi Lands Pits and Quarries Regulations. The ILA urrently do not have regulations governing pits and quarries, but generally follow the guidelines suggested in the above douments. 6.2 ob-ietiveg 6.3 Site-speifi management plans must onsider the requirements and onstraints of regional borrow demand and availability. Eah plan should ensure that eonomial reovery of quality granular materials is ahieved at eah pit while minimizing the adverse environmental impat. The environmental impat on the region an be minimized by restriting granular reovery operations to a selet number of pits, realizing that maximum extration from a pit will likely ause a slight rise in material ost. This ost inrease must be weighed against the environmental osts assoiated with high grading the better drained surfae materials. This loal pratie frequently results in numerous smaller pits being worked simultaneously or sequentially. Pit management plans should be developed primarily to maximize the utilization of limited resoures and to minimize environmental disturban=. Aess to soures of granular material should be by the most eonomial, least environmentally damaging manner. Areas with granular resoures loated nearby (Inuvik, Holman, Paulatuk and Sahs Harbour) an aess ertain resoures with all weather roads. Areas with distant resoures (Aklavik and Tuktoyaktuk) an usually only obtain borrow in the winter by tundra/ie roads or in the summer by barge, if the soures are loated adjaent to a waterway. Summer operations would require onstrution of temporary aess roads from the soures and doking failities for barges. The onstrution of these failities would

40 Page probably rquire large quantities of granular materials, and would signifiantly redue the reoverable volumes. 6.4 Pit Develm Site Preparation Work Site preparation should be onduted in advane of exavation to prevent ontamination of granular materials. This preparation also should preferably be arried out in winter to minimize disturbane to the surrounding terrain. Snow should be leared from both the area to be exavated and yard areas and plaed so as to minimize subsequent pit infilling by drifting snow. Topsoil onsisting of peat and organi soils, while typially sare, should be stripped where possible and stokpiled or windrowed ht the edges of the pit area. Windrows should be plaed parallel to slope diretion to prevent ponding of surfae water during spring, or ontamination of granular materials. Inorgani overburden materials should be stripped and plaed separate stokpiles or windrows, with similar onsideration of drainage onsiderations. he stripped materials are to be reserved for relamation purposes. Disturbed areas must be kept to a pratial minimum ExtrationMethods Winter reovery operations will normally onsist of the ripping of friable frozen granular material and pushing it into temporary windrows or stokpiles for loading. This type of extration an be onduted with onventional equipment inluding bulldozers with rippers, loaders, and truks. Poorly-bonded or friable granular material will usually be loated near the surfae of deposits that exhibit positive relief. If an insuffiient volume of material annot be obtained through ripping, blasting will be neessary. Summer operations will typially onsist of stripping and windrowing or stokpiling thawed layers of granular material with bulldozers, ommening when thaw has progressed about 0.5 m into the deposit. The yle of operation is largely dependent on the rate of thawing. and the drainage onsiderations. Thismethodallowspotentiallygreater annual reovery by progressively inreasing the amount of thawed material, and it may enhane drainage of the material in stokpiles or windrows.

41 a Page 27 Experiene has shown that winter exavation of frozen stokpiles windrowed the previous summer, may be just as diffiult as winter exavation diretly from the borrow soure unless the stok pile proess results in a signifiant redution in natural moisture ontent. Moisture redution from 10 perent in situ to 5 perent in a stokpile has been ahieved by use of onveyors during favourable summer onditions (Hayley and MaLeod, 1977). Frozen gravel stokpiles with a moisture ontent less than 5 perent are usually suffiiently friable for diret loading without ripping. Drilling and blasting of frozen ground in the winter has proven ost effetive for larger operations. The tehniques developed and used extensively at Prudhoe Bay, Alaska, is to remove gravel in lifts 5.5 m thik, by drilling shot holes 6 m deep on a 3 m pattern. Load fators are typially 0.9 kg of ANFO explosive per ubi metre of gravel to reate manageable size hunks. Typial speifiations for Alaska winter onstrution restrit the size of frozen gravel hunks to 200 mm Treatment of Massive Ie Logistial onstraints aused by massive ie during summer development of YaYa Lake pit are desribed by Hayley and MaLeod (1977). Where pratial, the extent of massive ie in a prospetive deposit should be defined prior to pit development. The development plans should inlude methodology for oping with ie bodies as they are enountered. Where pratial, large bodies of massive ie should be avoided. Thin, or less extensive massive ie within the granular material higher elevations should be exavated and wasted, or exposed to permit thawing during the summer months. Drainage must be onsidered with either method of disposal. Relatively thin layers of massive ie at depth may be permitted to thaw provided all overlying reoverable granular materials are removed during one extration season. Formation of thaw ponds as ie melts during the summer is inevitable this situation. Appropriate measures must be taken to ontrol drainage and to protet, and ensure aess to, adjaent reoverable granular materials. It may be desirable to identify and preserve thiker ie bodies at depth. If this material thaws it is likely to prevent reovery of adjaent materials, or result in

42 Page 28 major disturbane of the surrounding areas. A minimum over of 1.S m of granular material should be left as insulation over massive ie to prevent exessive thawing. Criteria for establishing the minimum thikness of massive ie beds whih should be preserved is influened by topographi relief, thikness and extent of granular materials, and the effet of thaw ponds on surrounding terrain. Operators involved with large extration operations may simply wish to exavate and waste the ie Drainage Considerations Adequate drainage of pit areas must be maintained to ensure availability of reoverable granular material and to attain required annual extration rates. Higher moisture ontents inhibit thawing, inrease exavation osts and redue material quality. Small amounts of meltwater runoff from ie bonded and thinly ie-lensed granular materials ould be allowed to seep into the surrounding terrain. Larger amounts of runoff, from thawing of large massive ie bodies, should be direted to retention ponds or sumps exavated in the pit floor. Where gravity drainage is possible, natural ponds or drainage dithes may be effetive at removing water from the site. However, exavated dithes are generally ineffetive in aras of high ie ontent. It is essential that pit drainage failities be maintained and updated frequently to ensure that moisture drains away from the working fae, and that ponded runoff does not aumulate on reoverable granular material. Where thaw ponds are allowed to form by exposing buried massive ie, or where olletion ponds are reated, are should be taken to preserve and maintain aess to adjaent reoverable granular materials. A development plan to adequately aount for pit drainage is partiularly important where summer extration operations are employed Waste Material All lenses of fine-grained material (silts and lays) found within the granular deposit, should be stripped and wasted. Waste material should be stokpiled near the stokpiled overburden for use in pit relamation. Fine-grained waste material at depth wil undoubtedly have high exess ie ontents, hene it may be

43 Page Resto- advisable to onstrut a dyke of drier overburden around waste piles to prevent flow of thawed waste onto surrounding terrain or into pit areas. Restoration measures are required whether the pit is being abandoned temporarily or permanently. All worked areas should be leaned of all debris, and graded to remove all topographi irregularities. Where abandonment is temporary, positive drainage away from existing faes and aess routes must be provided by grading or by dithing to ensure the future reovery of remaining materials. Berms should be onstruted at the top of pit faes, if neessary, to prevent suxfae runoff from entering the pit area. Prior to permanent abandonment, the edges of worked areas or pit walls should be reontoured to blend into the surrounding terrain. All obstrutions to natural drainage should be removed and any slopes graded to prevent runoff from hannelling and downutting. Sine thaw ponds and lakes and massive ground ie are ommon in the Tuktoyaktuk area, flooding of pits is an aeptable, and frequently inevitable, method of restoration. Areas whih are not likely to beome flooded should be smoothly graded and overed with stokpiled overburden and organis.

44 Page 30 Revegetation may be feasible in ertain areas by redistributing stokpiled organi topsoil and peat over the graded slopes of areas unlikely to be flooded, and by seeding or allowing reinvasion of natural vegetation, depending on the nature of the site and the quality of the topsoil. Fine-grained overburden soils are generally adequate for surfae relamation, however, the amount of naturally-ourring topsoil is very limited at some sites. The fertility of these soils may require enrihment for revegetation. 6.6 S' rte Suelh - Dev General The site spefii development plans presented in the following report subsetions pertain to seleted soures that are prominent in the development senario proposed for the ommunity of Inuvik The level of detail presented for eah soure reflets the amount of infonnation available for a partiular deposit Soure I400 Aess This soure is loated at the edge of the ommunity and is aessible by an all- weather road on a year -round basis Site Prwatioa The site is substantially developed and is onsidered and is onsidered to be nearly depleted.

48 Page YaYaLake Aess The soure is loated the south end of Rihards Island and is aessible only during the winter from the Inuvik-Tuktoayaktuk ie road. The site has experiened substantial development over the past ten years, but annual demands urrently plaed on the deposit are small in omparison to the volumes removed for past heavy onstrution. A substantial amount of readily aessible granular material has been reovered and several large stokpiles remain in the pit area. Unless large sale development again ours in the pit, additional site preparation will likely be unneessary. Small sale granular material reovery ativities will likely be able to obtain the required material from already stripped artas. In the event that extensive site preparation is required, ativitiesshouldbeonduted in aordanewiththereommendations presented in Setion of this report. Extration of granular material from the soure is urrently aomplished on an as-needed basis by exavating material that has thawed and drained during the summer. If large volumes of granular material are required, ripping of frozen ground and temporary stokpiling will likely be neessary. In addition it is likely that some oversized material will be present in the granular material exavated. Implementation of a sreening operation to remove unwanted sizes should be onsidered.

Depending on the extent and distribution of the ie, it may either be exavated and wasted or overed with an insulating blanket of granular material and left in plae. More detailed information on dealing with ground ie ontained in Setion of this report should be onsidered. The pit is partially exhausted, and future restoration should be undertaken onurrent with further borrow reovery. Restoration should be onduted in aordane with the reommendations presented in Setion 6.5 of this report and should primarily onsist of roughening the surfae and ontouring the abandoned areas of the pit to ensure adequate drainage ours and that large volumes of water are no trapped within the pit area. Alternatively, flooding of the abandoned pit areas is viable sine a substantial number of lakes and thaw ponds are already present in the area. Revegetation an be onsidered as pit abandonment proeeds.

50 Page RECOMMENDATIONS 7.1 Ged 7.2 Soure 1403 The reommendations ontained in the following subsetion pertain to additional work required to onfinn the quantity and quality of granular resoures ontained in a soure that is prominent in the development senario proposed for the ommunity of Inuvik and is presented with regard to all information olleted and reviewed during the study. In summary, the reommendation onerns the effort neessary to onfirm the produt available from bedrok soures and the volume and quality of material available from granular soures. Soure I403 (Campbell Lake Quarry) onstitutes a substantial soure of dolomite bedrok. At present, material; from the soure is primarily used for prodution of road surfaing material and at urrent and projeted useage levels, the soure will be funtional for many years. However, if speulative projets suh as prodution of erosion protetion materials for offshore pertroleum prodution failities our, the soure woud be evaluated in more detail to determine volumes of large bloks. its potential to supply large It is reommended that this be aomplished though a geotehnial/geologial drilling program to determine the volume and size of rok bloks that ould be produed from this soure. 7.3 Soure I407 Soure I407 is relatively unexplored although it supplies a substantial portion Inuvik's Class 2 material. At present onsumption rates the soure should last for many years, but it is reommended that a limited geotehnial drilling program be undertaken at the site in an effort to determine and prove the volume and quantity of granular material that will likely be available from the deposit over the next 20 years. of

If this ours it is reommended that both of these soures of highway onstrution material; be investigated in detail in order onfirm to the quality and quantity of granular material that may be obtained. 7.5 soures In the event that it beomes desirable to obtain large rok bloks from Soure R28/29, the soure should be evaluated with a geotehnial/geologial drilling program designed to detemrine the volume and size of rok bloks that ould be produed from the deposit L (I m
