Richard C. Bocking Two great rivers, the Nelson and the Churchill, cut com- pletely through the Precambrian Shield of northern Mani- toba bringing water from the interior of Canada to Hudson Bay. \Vaters flowing to the Nelson begin their journey on the eastern slope of the Rockies, crossing the three Prairie Provhtces via the Saskatchewan River. The Saskatchewan enters Lake \Vinnipeg at Grand Rapids. All rivers that drain into J .. ake \Vinnipeg, including many beginning in northwestern Ontario, contribute to the flo\y of the Nelson. In total, this. vast watershed covers some 414,000 square miles. The headwaters of the Churchill likewise begin far to the west at Beaver Lake ncar Lac Ia Biche, northeast of Edmon- ton. Its waters· flow eastward acros.c; the ·northern plains of Alberta and Saskatchewan to Lac Ile-a-la-Crosse, there meeting the Precambrian Shield. lt~rom the Manitoba~ ·Saskatchewan border, the river flows northeastward through a magnificent rl)ain of lakes, roughly paralleling the Nelson to the sottth. The Churchill watershed covers an area .of about 115,000 .square mil-::-s. . Though these rivets liit several hundred miles apart, the height of .land. separating the Churchill at the Southern . Indian Lake area from waters. flowing southward to the Nelson is low and very short-so short, in fact, that the idea of diverting the Churchill to increase 'the volume flow of the Nelson, for power purposes is an ~'engineer's dream." In the late 1960s and the first two years of the present decade, this . dream has come closer to reality beca\tse of government- approved plans of Manitoba Hydro to build a dam on the Churchill at its outlet from Southern Indian Lake. The dam would create an ertotmous r~rvoir stretching some 11 0 miles southward to the headwaters of a small tributary to th~ Nelson-· .the Rat-Burntwood system (see map). The. lower 250 miles of the Churchill River valley would be almost completely cut off and receive significant flows only Editor'l nott: This paper has been published separately as Canadian Nature; F~eration Special Publication No. 2, january, 1973.

On the 29th day enough lily pads must grow to co,·cr half the pond in only· one day. This'is the kind of "need" that the power developers st1y must be met in the near future. DEVELOPING HYDRO POWER IN MANfl'OBA Tht: slow early growth of power demand in Manitoba, starting over 60 years ago, is analagous to the early days of the pond. As indicated by the projected need (load g;·owth) curve for ~ianitoba, the first hydro-electric plants needed to satisfy the demands were small and widely spaced in years. The initial plants were located on the \ Vinnipcg River starting with the 28 megawatt (Mw) installation at Pinawa. It was not until the late fifties that all ofthc twailable drop in · the \Vinnipcg River had been utilized by the additional six dams listed in Table I. By the mid-sixties, however, the increments of power needed to satisfy the demand were in the Drder of hundreds of Mw, and the installation of new plants took place every few years. The solution to satisfying the geometricaily growing demand was to dam the next large riv:er to the north, the Saskatchewan. The Grand Rapids plant above Lake \.Vinnipeg on the Saskatchewan created a vast reservoir by flooding over 600 square miles of upcleared delta land and lakes. The addition of Grand Rapids (472 Mw of capacity) to the system !latisfied the demand for only six years. However. the hydro-electric potential in the northern half of the provint"f.; was. vast and untapped. The large outflow system from La~e \ \rinnipeg, the Xclson River, was well suited for large scale power develop· . ... : . . -. ).~ ": .. _, . ·-.. '-='" . ... . - . . 'J. ) . I . t# • • ' ' . 5,000 Mw of power would be available by damming the Nelson at eight to ten places (Table II). The feasibility of developing Nelson sites had been proven with an initial plant, the Ke!sey Station, located just upriver from Split Lake~ The Kelsey plant was constructed primarily to supply ·the International Nickel Company mine at Thompsop, Manitoba. Construction of the first Nelson River plant for the southern system began at Kettle Rapids in 1968 and now nears completion. This plant's capacity of over l ,200 Mw will be transmitted southward by a federally assisted DC transmission line to meet the demand for an additional six years. Exploration for the construction of a second plant on the Lower Nelson at Long Spruce Rapids has now commepced. As indicated by the projected load growth curve, plants of over .1 ,000 M w must be. added every five to six years to meet the increasing demand in the 1970s. To improve the efficiency ofthes~future Nelson plants, works to. regulati! the ftow of the Nelson from Lake Winnipeg are now under con- struction. The Churchill River diversion would dramatically increase the size of the Nelson flows (b1r about 30%). Now, in the 1970s, according to ~1~anitoba Hydro, the suppl~· of hydro-electric power has reached the lily pond's 29th day of growth, where entire rivers must be developed in a single project to meet the projected demands. The Churchill is the last great river capable of sustaining such growth for even a few years in Manitoba. · lf the l'emaining potential of the Nelson River is applied HUDSON BAY I I ' J · ·to the power demand a11d projected intO the future at a consetvative 7% growt~rate, it can be seen that the Nelson alone will carry th~ n~w demand to the year 1990.

The total effect of the Churchill River diversion will be to add 1,900 Mw to the system, but this allows the'load demand_~ be carried only into the year 1994. \Vith the trcmcndO\lS annual increments of power that will be needed in the 1990s, the total effect ofthe entire diversion project will be to delay the need to develop alter1;1ative sources of power for only four to six years. In spite of a scarcity of undammcd rivers which will occur by 1990, power plannerS and politicians advocate. the diversion.ofthc Churchillimmediately,·that is, before· the Nelson is developed. They bolster their argu-. ments by actively promoting greater consumption of elec- tricity both in the province and for export. Although the 1972-1990 period could be used to assess the true value of the last great river, Manitoba wiH reach its 30th day of development in the lily pond analogy by 1974 if the move to dam the Churchill cannot be stopped. Of course, saving for the future always costs today's con- sumer. 1Yianitoba Hydro's. estimate of the extra cost of pre- serving the Churchill for 18 years is a S% to 1 O% increase in power costs. They argue that saving the option on the Churchill is not the cheapest way to produce power, their "' ~--:.- FIGURE 3 GEOM~TRIC GROWTH OF POWER DEMAND AND SUPPLY IN MANITOBA only interest. Unfortunately, cheapest power is also the cheapest treatment of native communities and ofNianitoba's livable environment,. It is also the cheapest ~lf!ritagc of na- tural resources that can be passed on to future generations . Is a few percent of etlidency worth it? 'THE DIVERSl'ON A description of the Churchill River after its diversion inust be based on smaller projects elsewhere since diversion proj- ects of .the extent proposed do not exist. Essen~ially, in the · diverted form, the 10\ver 250 miles of the river valley will have only a small flow from local drainage occupying the large unfilled channel. The only appreciable flows will occur , in early summer and last only a few weeks whe11 the Southern Indian Lake reservoir is overtopped at the proposed lvlissi Falls Dam. 'Vhether the smaller flows are maintained during the winter in the large channel without remedial. work or extra releases is unknown. In effect, the abandoned channel aspect will be maint_ained by short bursts of peak flows for- ever, and no new natural regime will be allowed to establish. The whole ecology of the Lower Churchill will be drastically changed to some form unique to an artificial regime. In the Southern Indian Lake-Notigi Lake reservoir, 0\·er 300 square miles of shoreline areas will br. flooded as existing lake levels are raised up to ten feet at the uppet end and 60 feet at the lower end of the reservoir.

C~dar Lake i~­ pounded in 1964, or the Kettle Reservorr 1mpounded m I 970, the time requir~d for the re-establishment of lake shores in permafrost areas is unknown, but is definitely more than 30 yea~. · The small tributary channels of the Rat-Burntwood sys- tem that will receive tr..e flows of the Churchill will also undergo an unspecified period of instability. The . flows in the 200 miles of channel connecting the Churchill and Nel- son will be increased by over 500% causing large lake level fluctuations, unstable shorelines, and continuous reaches of channel erosion followed by downstream deposition in the slower-flowing expansions and lakes. The location and fre- quency of sediment and floating debris will depend on the sequence of developmento( ndditional reservoir sites along these diversion routes. These proje('tcd effects of flooding have been confirmed by even the most recent :Manitoba Hydro study where shore- line clearing and debris booming of travelled routc!S in the proposed reservoir is recommended for safety and appear- ance, and where the deliberate creation of cleared boat re~¥r~ areas in other parts. of the .reservoir is recommended. 1( ,u;ast study, released only a few months ago was commis- siooed by the chairman ofl\fanito!:>a Hydro <tnd directed by P. D. McTaggart-Cowan, the executive director of the Science Council of Canada. The terms of reference are typ- ical of the limited studies undertaken to date in that it is assumed that: the project must prqceed i111mcdiately; the study must be short-term; and tlu! recommendations are to deal only with the mitigation of environmental effects.

MOVING· TO UlPLEl.IENT THE PLAN Although studied as far back as 1919, serious consideration of the Churchill diversion by Manitoba Hydro first resulted from a study by the firm of Gibb, Underwood & McLellan in I 964. In 1966, the Conservative government of Manitoba ·allowed Manitoba Hyd'ro to enter into an agreement with th· · "7ederai Government to proceed with the development oUNcJson, including a high level diversion of the Chur- chill. and construction of a 560 mile DC powe1· line to southern Manitoba. Public announcements made with en- thusiasm by Premier Roblin were taken at face value by a public unfamiliar with norther~ gcogt"nphy, its people, or the values of other resources in the region. The Manitoba \Vildlife Federation (12,000 members) pressed forbiologkai and environmental studies to be carried out coincident with Hydro investigations and planning. A preliminary study by the University of ~lanitoba recommended in-depth socio- logical, biological and environmental studies. But, funds for the recommended studies were refused, and the report is being kept secret and has still not been made public. On December 20, 1968, an open letter expressing det·p concern regarding the proposed high levd diversion was TABLE U FUTURE GRO\VTH OF THE ~IANITOBA HYDRO SYS'rnli Without Diversion of the Churchill River Capacity {Mw) Station 800 Kettle Rapids 168 Jenpeg• 420 Bladder Rapids • 320 Kelsey• 700 Gull Rapicls • • 600 Long Spruce: 1300 Limestone Rapids*~ 600 Gillam Island 0 Burntwood River Full utilization by the year 1990.

Harry Enns, .then ~finister of ~lines and Natural Resources, by a group of University of ~Iani­ toba professors. Publication of the letter first made the public aware of the probable annihilation of the South Indi;m Lake settlement, and of widespread extreme environmentnl damage. A Southern Indian Lake Action Committee was formed by private citizens to further inform the public by holding a serie~1 of public meetings. In the meantime, Manitoba Hydro applied for a license to proceed; and public hearings under the Water Powers Act (Man.) were announced. At the stormy sessions which followed in January 1969, Manitoba Hydro representatives stated that Hydro's sole rt~sponsibility was to provide adequate power at the lowest possible rost. Opponents of the plan objected vigorously to this unilateral approach, blaming the government more than Hydro. The main objections centered on the disruption of the South Indian Lake community, lack of any in-depth rcsourC'e studies, and reftasal of the government to make public such reports as they had. The hearings wc~c adjourned without a recommendation, and in February lawyers representing the South Indian Lake and Granville Lake communi tic-.; sought and obtained an injunction to prevent Hydro from proceed- ing unless the hearings were properly concluded. To circumvciit the injunction, the government introduced Bill 15 in the ensuing legislative session. If pa~d, this Bill 9 • . i.\ ; l·• . .,Y . ' ; ... ~ ~! 1 • I ) i. \ I•' ~ ~; I. I I j 'I ,l :j .

Opposition parties (including the present NDP government) fought the Bill dgorously on the basis that lack of .information and govern- ment refusal to release reports and other vital information prevented any intelligent vote in the legislature. The Bill did not pass second reading since tht: House was dissolved in the spring of 1969 and an election called, partly on this issue. In a surprise vote the Conservatives lost, and the New Dem- ocratic Party assumed the reins of government. Premier Schreyer had stated prior to the election that, if elected, he \vould not allow the high level diversion and would seek other alternatives. The NDP government called in David Cass-Beggs, former chairman of the Saskatchewan Power Corporation, to review Hydro's plans. In his report to the l<!gislature, Cass-Beggs ~onfirmed that alten~~tives tee high level di"~:ersion could be found. On September 23, 1970, Premier Schreyer annom'lcea nlternative plans to develop Lake \Vinnipeg immediately for the dual purpose of flood control and regulation of the ~elson River for power purposes. He proposed that the diversiou at Southern Indian Lake should indeed proceed, hut must not raise the level of the lake more than some ten feet. The announcement appeared to give government sanction to the qa~s-Beggs recommendations. (These recommenda- tions are contaii)ed in his foreword to a Manitoba Hydro Task Force Report on Expansion of Gmnating Capaci!J in .\faniloba, dated Septcm~r 23rd). At the same time, federal- provincial agreement to study the eft'etts of hydro-eiectric dc.·velopment on aU rcsourc~ and settlements was being 50 MILES FIGURE 2 PROPOSED CHURCHilL RIVEtt DIVERSION AREA Force Re\)ort's introduction shows that the authors of the report had their minds already made t,tp! A more detailed stud;' of tile effect of tht cotzlrolled regime on resource values is at present being undertaken under joi1zt Federa/-ProvinciDl auspices, but while it lVill provide im- portant information for tks detailed planning and operation of tltt control project, there is no possibility of it leading to any basic revision Dj the concept. 3 The agreement covering the "detailed study', was not signed until a year later, in September 1971, following re- peated re-drafting because of objections raised by the chair:· man of Manitoba Hydro. The lost time was critical, par· ticularly since findings would represent the only det~ilec study of effects on natural resources in the ChurchiU.-Nelsor and Lake Winnipeg project areas. Two million dollars havt been committed and more will be, but "there is no ·possi bility of it leading to any basic revision of the concept"! . Lack of basic datet and the failure to undertake in*depd quantitative resource studies, in spite of pressure to do so is a serious indictment of both governments concerned. Evei -the one detaile~ study, which deals. wi~h the ~ffects '?n re sources only, will not ~·completed m t1me to mftuence th, course of events in any significant way. A current an~lysis offederal participation in the Churchill Nelson study further confirms the peripheral nature of th research by noting:. • • • • the gowrnments asked if tllert was an opportunity jor and sufficient time to a&l1im meaningful results, or is this (slutf.1) essmtial/.1 a wli.J4r.JJtUia to tover decisions HIT.~~3U11 taken.' • ".A Alth6tigh · thcffJhurchiU i$)th~ last rimj~ river, plans to divert local systems to tlte di\·ersion area a~ being enter- tained •.

There. would then be one continuous chain of impoundments stretching northward from Nobgi, 300 miles to the Northwest Territories. · At the time of writing, the present chairman of Manitoba Hydro, David Cass-Beggs, has moved on to head British Columbia Hydro. However, assuranc .· s by Premier Schreyer of Manitoba have been given that problems a5.'iociated with northern hydro development have been solved by the former chairman, and plans to divert the Cht~rchill River will pro- ceed as rapidly as possible. In a final move of arrogance, on December 8, 1972, the Minister responsible for granting a license to Manitoba Hydro for the diversion, the Hon. SydneY. Green, announced that no license would be required, no hearings into the issue would be held, and no compensation to native communities would be necessary as it had been decided in Cabinet to grant permission to 1\:Ianitoba Hydro to proceed by an Order in Council. The legality of this move is now in question. A RIVER OF UISTORY AND BEAUTY The Churchill River, in its course through the .Precambrian Shield, is today in its natural state except for a power dam ·and a minot> in-channel.reservoir at Island Falls, Saskatch- ewan .. From the Saskatchewan border, the river surges east- ward and northward through l\1anitoba for 250 miles to Missi Falls at the outlet of Soutl1ern Indian Lake. Its char- acter is that of a magnificent chain of lakes broken only by short stretches of river where rapids and falls occur. That it was known and weli-used before the onset of Canadian his- tory is apparent from the large numbers of archeological sites discovered since the flooding and diversion were first discussed. Approximately 180 sites of up to 35 acres in extent have been found within the area,. and most of them· will be · inundated. Age of som.c ofthe site! is tentatively dated at 6000-7000 years. In modern times the Churchill has lain remote, known only to scattered native communities along the lake shores and to canoeists who have retraced the early fur trade routes of western Canada. Duke \Vatson, an internationally-known wilderness trav- eller, in a letter to Premier Schreyer inJ une, 1970, described the Manitoba portion of the Churchill in these words: .. l1e C/,urcllill River lzolds a very special $i&nificanct for me in that I./rave traversed it by canoe in its entirt~ across Manitoba. I ltavt camped at many silts along its course; 1 luJ.ve sailed on Southern Indian lAke aud tlte other big lal.:es of lltt Clturcllill sy.sttm; and lltavt visital t!tt com- muni~y of Sout/1 lntlz'an Lalct, in itstl}an insfJiration. 1 should add that wilderntss travel t/zr(;ugltout JVortlt A.mtrira ltas httn a recreational pursuit of mine for mai!JI ;·rars. Out of the nwnerous qips, lloU:tr:tt, tilt lower Churcltill, consisting of t!te sections which would eilher h~ flooded or divrrtrd of most of tht rolumt, ranks as 11!V most outstanding rerreational and esthetic e:«fttrienrt. Tlirrt is simply nothing like it tlstwhert! In another letter to Premier Schreyer dated September, 1971, two canoeists wrote: rve lzazle SJ1ent months zvitll villagers in Alaska, rtmote mountain rt'gions o/ the U.S., and canoeing and hu11ting in Canada.

The fishing, wildlife and pure natural btauty are unsurpassable. Sigurd F. Olson, internationally-known author and out- doorsman and leader of the Voyageurs' group from Ottawa (that has included Prime Minister Trudeau and the late Blair Fraser), has traversed the fur trade routes of Canada. In a letter to G.\V. Malaher, he has written: lltavt travelled the Churcltill Riz•er in 1955 from Ile-.a-la- Crosse near its fttaclwa/P.rs in SaskatclmvaTl some 500 miles to Cumberla11d House and the Pas on tlte Saskatchewan River, t!tcn later in 1001 from I.ake Pukatawagan through Grall~·ille a11d South Indian, thtn down the Rat to its con- fluence witlz tire Burntu:ood mding at tire mining tou:n of Thompson • • • The area that will ,,,. flootftd on tlte Clwrchill is ortt of·· J:te most beautiful regions of Canada.

If tile South Indian jwyer.t is abandoned, future gmtra- tions u:il/ bless the vision of tile decision makers of today. The Churchill wili soon become accessible directly by road from the south, and it will be possible for many more people to enjoy its wilderness beauty and wildlife. The Ruttan Lake mine, now under construction, lies a few miles south of Southern Indian Lake, while the new townsite for the mine is located on the ChurchiH River where it enters Southern indian Lake at Leaf Rapids. A new highway con- necting Leaf Rapids with the southern road system nears completion, providing the first land link from the south with the Churchill River. The large mining developments at Flin Flon, Thompson, Lynn Lake and Ruttan Lake lie nearby to the south and west. · In addition to providing a stable loC'al economy based on fish, fur, and game animals, the Churchill provides a habitat for a significant portion ofthe northern Manitoba waterfowl population. The lower 250 miles· of the channel that is. trimmed of large vegetadon by icc and high flows each winter provides a major nesting and rearing area. At the end. of the river the Churchill estuary on Hudson Bay also plays a role in providing a fresh water habitat for popula- tions of white whales, capelin and seals. 11 1 ~ I I l ! j l ! : i !

The main source of livelihood was trapping, and until some years ago their trapping grounds were open to invasion by any itinerant trapper from the out- side who ('hose to compete with them.

The l~ke was opened to commercial fishing in ! 942, and .so a second source of income was provided. At first there were conflicts of interest. There was danger of introducing a new and additional population of commercial fishermen be- cause the men at South Indian had no experience in com- mercial fishing.

This po,rer '"'ill not be needed until close to the turn of the century. Yet n.:Ianitoba Hydro is anxious to proceed with the · divt"rsion almost immediately. To "justify'' the rapid cxpan .. ·sion of power developments, 1\..iaiJitoba Hydro continues to light its offices in \Vinnipcg for 24 hours eac-h day and has conducted an intense publicity campaign advocating that people use mare electric power. Such advertising for self- gratifying growth should be made illegal. Pltysically, the proposed diversion project would begin a cycle of long term erosion and deposition along 250 miles of local river channels-the Rat-Burntwood system, and would d~troy the n~turallandscape and habitat of 250 miles of large scale river channel-the Lower Churchili River, and 370 square miles of shoreline environment spread out over thousands of miles of mainland and islands-the Southern J[ndtan Lake-Notigi Lake area. Cullurally, the diversion would remove the traditional in- dependent livelihood of the South Indian Lake community and other dvwnstream fisheries and would substitute untried one-way compensation. • -rragically, the diversion would permanently destroy Mani- '!',.,a's last great river before its values for7ecreation, habita- tion, wildlife, or wilderness are gauged, realized, or under- stood. All this for the sake of a power scheme that could be delayed for at least 20 years and perhaps forcver.O REFERENCES The quotat}~n on page 4 i~ from Co1!ada's Watrr: F~r ~altJ, copyright . 1972 by Rtcnard C.

Comment a) and b): Request a listing of all stationary air pollution sources expected during construction_and -operati-?nj aud.indicate the emission rates for TSP, NOx, SOx, CO, and hydrocarbons; indicate type of fuel. Emission estimates were made for the diesel electric generatox, refuse incinerator, concrete batch plant, aggregate screening plant, and oil heater emissions fr:-omthe .Watana and Devil Canyon camps and townsites .. The estimated emissi~n rates for particulates, sulfur oxides (SOx), nitrogen oxides (NCxi, carbon monoxide (CO), and hydrocarbons from each of the·se sources are listed in Table 1. DieselElectric Generator-The diesel generator at the Watana site will provide interim electrical power for the camps at both Watana and .Devil Canyon.

The generator will use an averag.e of 723 gallQns per hour of No •. 2 di~sel fuel. Estimated. emissioq~ from the ' generator are s.hown in Table 1. Refu·se Iti.cinerator -Refuse from the Wat~na and Devil Canyon camps and pe~an;ent townsitea will probably be incinerated. As a. worst case estimate, the colilbined populations at: the Watana and Dev:il Canyon sites will produc~ a~ estimated 14 tons per day .of refuse, based on .a: conser-· ·· vative refuse generation rate of 5 lbs/person per day (TchobanQglous, 1977}. Estimated emissions from the refuse incinerator. are shown in Table 1. It was assumed that the incinerator will be equipped with a. water spray sc.rubber for particle removal. Batch Concrete Plant -One or more batch concrete mixing plants will be used. The estimated peak capaeity of the plants is 1,000 tons per hour, producing concrete with a density of 4,000 pounds p.er cubic yard. As s.hown in Table 1, particulates are the only significant pollutant emitted from the plant, at an estimated emission rate of 44 tons per year. Aggregate Screening Plant -River gravel from the Susitna River will be used as processed gravel fill in the dam and as aggregate for concre1te .. Tlte gravel will be dredged and stockpiled along the river before washing and screening prior to use.. Particulate emissions from the washing and screening process should be ne.gligible because of the hi:gh moisture in the gravel (EPA 1977) .. Camp and. Townsite Emissions -The major emissions from the camps and permanent townsites are expectetl to come from residantial oil heate.r:s. The fuel type \!Sed will be No. 2 distillate, with .a :0.25% sulph~r content. The population. at the w·atana site will use an estimate 6,080,000 gallons per year (gpy), while the population at the Devil '6.0012 3 •• : ~ . .. . . ~ ' . qa4yQn si..~e'' will. yae. a,430',0U9 SPY•· ·· Estimat~d oil heater emiss;ons fr rm t. b.e t_vo ··ite$ .. · .. ·are shown in Table 1 • . ? . l'·.

A simplified scr.eening moelel analysis is sometimes suitable for i.solated sources such _as the diesel generator (EPA 1980). Where applic,able, ·.the maximum expected 24~hour pollutant concentrations can· be· estimated using· suitable "worst case" assumptions: low wind speed (typically 2.5 meters per second) and poor atmospheric dispersion .(F-class stabiity). If the modeled "worst caae11 concentrations are well below the. applicable 24-hour standards, then the PSD applicant may not be required to conduct additional, more sophisticated, air quality modeling • BACT analyses will be: required for TSP, so 2 , NOx~ CO, and · hydrocarbons emitted from the generator •. Each analysis must demonstr.ate that the proposed air pollution control strategies are effective and use readily available equipment and materials. It is doubtful that the flue gas treatment would be required for an internal combustion diesel generator. However, it is possible that BACT for TSP and so 2 would require use of low ash and low sulfur fuel oil., c. It is unlikely that a full year of meteorological and air quality monitori·ng will be required.

Emission Standards -The diesel electric generator (rat.ed at 16 MW peak capacity) would be subject to the proposed federal NSPS standard for NOx emissions from internal combustion engines (Federal Register, 1979.). Emissions from the diesel generator, concrete batch plant, and the aggregate screen will be limited according·tn_ the emisson standards established by the ADEC in 18 AAC 50.050. Emissions from the refuse incineratorwill be limited according to 18 AAC 50.040. Operation of residential wood stoves will be limited by the practices described by 18 AAC 50.085. Comment d): Indicate results of any air guality calculations or estimated impacts relative to these sources. The EPA-approved screening procedure was used to estimate the worst case air quality impacts .near the diesel generator, refuse incinerator, concrete batch plant, and the Watana and Devil Canyon townsites (EPA 1980bl. To estimate the maximum 24-hour average polJ;;tant 60012 6 r . ;:"~ .~.. . . ~ . ..·• c:oncentratioQs downwind of the Watana sources, the wind ti'as a.ssu!lled to t --• -bl~ up the valley along· the Tsuse~a Creek at a constant· <2 ~s mps wind - s~ed with a F-class atmospheric stability. The EPA screening apprrJach recommends the use af the 2 .. 5-mps wind speed and F--class stability as the. "worse case" conditions. As shown in Table 2, the measured wind .. speeds at the. Wat:ana site are generally greater than 2.5 mpa, so the use of that wind speed as the "worst casen condition should provide conservatively high pollutant concentrations. The EPA approved COMPLEX model was used to estimate pollutant concentrations along the complex . terrain. Under tl.le assumed conditions, the maximum pollutant ·... concentrations occurred at a point roughly 3 km north of the wa·tana Townsite. Similarly, the maximum air quality impacts near the Devil Canyon townsite were modeled by assuming that the wind blew up the valley along Portage Creek, at 2.5 mps with F-class stability. The estimated worst case 24-hour average ambient pollutant increments caused by the point source emissions are shown in Table 3. The estimated maximum increments for TSP and so 2 are well below the allowable PSD Class II increments and ambient air quality standard concentrations for those pollutants. Based on the low calculated 24- hour concentrations for all the pollutants., the 3-hour_, 8-hour, and annual average concentrations of NOx, CO and hydrocarbons will probably also be well below the app~icable Alaska ambient standa-r;ds for those averaging times. The low calculated pollutant concentrations also indicate that ambient air quality monitoring will not be required as input to the PSD review for the diesel generators. Ambient monitoring is not required if the maximum impacts of the PSD source are below significance levels for the appropriate pollutants (EPA 1980b). The calculated impacts from the diesel generator are near or below the significnnt monitoring concentrations, as shown below: 60012 7 '! • ... . ' • ,' , r. .. ::, I i ' TSP Carbon Monoxide · .

Stephan Lake .and Fog Lake #4 (Sees. 13 and 14, T. 31 N., R. 5 E., Sec. 18, T. 31 N., R. 6 E., ·seward Meridian) have been determined to be major waterways. In addition.,. the Susitna River has been determined to be a major waterway. Stephan Lake has an extensive history of significant use for ac.cess purposes. As the site:·of several private lodges and as the major fioatplane staging area for several townships, it serves as the point of origin and terminus for access to large areas of land which will remain in public ownership. \\"bile all of the Fog Lakes have been used for access purposes, Fog Lake #4 . appears to have seen the most use for accessing those lands c1utside the selection area which will remain public. The demand for access to public lands south and ·east of Fog Lake #4 will continue to place a premium on this lake as a fo.cus for this access. The Susitna River provides a major avenue of access to and through the public lands in the region surrounding the subject selected lands. The obstacle to, traversing the entire length of the river presented by Devil's Canyon, does . not negate the use historically found on the river upstream from the canyon~ Current information reflects a cgnsistent, long term u.se of the river above Devil's. Canyon for both recreational river floatL~g and for general access · purposes. These uses generally originate upstream on public lands at point!; such as the Denali, Highway crossing and the Tyone and Macclaren Rivers. Travel downriver ends just above Devil's Canyon requiring access off of the river. ALLOWABLE USES: : . All easements are .subject to applicable Federal, State, or Municipal corporation regulation.

Rusponse: A total of 11 sites have been considered as potential hydroelectric projects in the Susitna Basin and vicinity areas. (Some of these sites would be eliminated by development of other sites). A review of past studies indicates some of the data you requested are not available, since preliminary schemes, including specific.dam locations, types, and heights were not developed for all the sites. Copies of u.s.G,S. maps of the requested potential sites are enclosed. Alignments have been sketched on the individual damsite plans. These locations, although approximate~ are felt to be within the site area projected for the potetitial hydroelectric projects. A table entitled "Su!IID8rY D!lta on Proposed Rydtoelectric Projects" is also provided which contains available data on dam height and type, reservoir surface area, and inundated and disturbed area for these l!ites. Additional related information concerning reservoir elevations and storage , where available, is also included. B/6/2 • • • SllottAAY DATA ON PROPOSED HYDROELECTRIC PROJECTS . , '·, . ..l· ,.,_ .
