A Case Study of the Pebble Exploration Project
Institute of Social and Economic Research ⢠University of Alaska Anchorage ⢠January 2017
From 2002 until 2013, the Pebble Mineral Exploration Project explored a big deposit of mostly
copper, but also gold and molybdenum, in the Bristol Bay region of Southwest Alaska, about 17
miles northwest of Illiamna (Figure S-2). That exploration stopped in 2013, when a major project
partner withdrew. But before that, developers spent millions of dollars, and in the last years of
exploration annually employed more than a hundred residents of Bristol Bay communities.
This paper describes jobs and income the residents of 18 communitiesâin the Lake and
Peninsula Borough, the Bristol Bay Borough, and the Dillingham census areaâgot from 2009
through 2012, the last full year of exploration. Most residents of these communities are Alaska
Native, and the communities are smallâmost with populations considerably smaller than 500â
except for Dillingham, where nearly 2,500 people live (Table S-1).
How local communities can capture more economic benefits from rural resource projects is an
important question in Alaska, and the Pebble exploration project offers a useful case study. But
we want to emphasize that weâre neither advocating nor opposing a potential mine at the Pebble
site. The proposed mine has been enormously controversial in Alaska and elsewhere, because of
its proximity to the world-class Bristol Bay salmon fisheries. We looked only at local jobs and
income exploration created, to shed light on the potential for resource development projects to
help rural economies. Our analysis is based on data from Pebble Limited Partnershipâs
exploration-site database, augmented with information from contractors. What did we find?
⢠About 43% of those who worked at the Pebble exploration site anytime from 2009 through
2012 were from the Bristol Bay area. That amounted to about 300 local residents who worked at
the site some time during the study period (and may have held more than one job over the years).
Another 37% of workers were from elsewhere in Alaska, and the remaining 20% were mainly
from other states or Canada (Figure S-1).
⢠The number of workers from Bristol Bay
increased over the study period, and so did
employee retention. In 2009, 111 local
residents worked at the Pebble site, increasing
to 157 by 2012. More employees also stayed on
the job from one year to the next, with retention
at just over half from 2009 to 2010, climbing to
two-thirds from 2011 to 2012 (Figure S-3).
⢠Bristol Bay residents worked at 56 kinds of
jobs in the study period, almost all seasonal.
The most common jobs they held were drill
helper, bear guard, and skilled laborer. The average hourly pay was about 15,000 a year from those mostly seasonal jobs. About 65% of workers
were men and 35% women (Figure S-3).
2
⢠Communities closest to the exploration site got several times more jobs and income than those
farther away. We grouped the study communities into three regions, based on their proximity to
Pebble. Communities closest to the site are mostly around Lake Iliamna, and on average per year
about 100 workers came from what we call the Lakes region. About 25 a year were from the
3
Intermediate region and 8 from the Distant. On average, workers from the Lakes region collected
a total of nearly 499,000 for those from the Intermediate
region and $100,000 among those from the Distant region, where communities are more than
100 miles from the Pebble site (Figures S-2 and S-4).
⢠In the Lakes region, where communities are very small (Table S-1) exploration employment
was a large share of total employment: approximately 14% of the total workforce from Lakes
communities worked at the site during the study period. The regions farther from the exploration
site, which have larger populations, saw much smaller employment effects: 3% of the total
workforce from the Intermediate region and barely above 0% from the Distant region.
⢠Even within individual regions, community employment at Pebble varied significantly. Iliamna,
where exploration operations were based, and Newhalen (with road access to Iliamna) had the
most employeesâan annual average of 40 in Newhalen and about 25 in Iliamna, followed by
Nondalton with about 16. Outside the Lakes region, the only community with more than an
average of 10 workers a year was Koliganek. But even within the Lakes region, not all
communities had a significant number of workersâPort Alsworth and Pedro Bay had fewer
workers than some places in the Distant region (Figure S-5).
4
⢠To get a sense of what Pebble income meant to the region, we compared it with income from
two important sources: commercial fishing and Permanent Fund dividends. The exploration
project brought more income into the Lakes region from 2009 through 2012 than did either
commercial salmon fishing or Permanent Fund dividends. But the Intermediate and Distant
regions have more people, rely more on salmon fishing, and had fewer residents working at
Pebbleâso Pebble pay in those regions was a much smaller source of income. As Figure S-6
shows, income from Pebble in the Lakes region from 2009-2012 was several times more than
from salmon fishing and two-thirds more than from Permanent Fund dividends. By contrast, in
the Intermediate region Pebble pay was significantly less that from either commercial fishing or
PFDsâand in the Distant region it was an insignificant amount compared with the other sources.
What can the Pebble case study tell us about the potential for rural development projects to
benefit local economies?
⢠Residents of Bristol Bay communities and other Alaska places were able to capture a big share
of exploration jobs and income. During the study period, 43% of workers were from Bristol Bay
communities and another 37% were from elsewhere in Alaska. A number of things contributed
to this high local-hire rate, including Pebbleâs local hire coordinator; its work with the state
government to get training programs and with non-profits to help qualify local residents for jobs;
and its contracts with local Native village corporations and other businesses.
⢠Jobs and income going to Bristol Bay residents increased significantly between 2009 and 2012.
Partly thatâs because the developer was spending more for exploration, creating more jobs. But
the number of qualified job applicants from the Bristol Bay region also increased over time.
Pebble personnel report that by 2010 or 2011, there were more qualified Bristol Bay residents
looking for jobs than there were jobs available.
⢠Proximity made a difference: even though most project employees from all communities were
housed at project headquarters in Iliamna, residents from the villages closest to the project site
got more jobs. From 2009 through 2012, an average of about 100 residents per year from the
Lakes region worked at the project siteâabout 14% of the total workforce from seven small
villages. Prospective workers from places farther away may have taken into account how
difficult it would be to travel home for time off workExecutive Summary / Background / Methodology / Community Workforce / Community Effects / Appendice
Assessing juvenile sockeye salmon (Oncorhynchus nerka) energy densities and their habitat quality in the Chignik watershed, Alaska
Thesis (M.S.) University of Alaska Fairbanks, 2004The Chignik watershed, on the southern side of the Alaska Peninsula, supports a large salmon fishery vital to the local economy. Recent morphological changes to the watershed generated concern regarding the sockeye salmon (Oncorhynchus nerka) stock that rears in Black Lake, at the head of the system. Studies of the Chignik watershed to date have not incorporated energy density data to explain the life history strategies of Chignik sockeye salmon. Re-estimated condition factor parameters improved our understanding of the length-weight relationships to fish health that isometric models described in Chignik sockeye salmon. Subsequent comparisons of age, length, weight, location, and temperature data to energy density indicated that Black Lake fish, which were all age 0 fish, were significantly affected by temperature and had energy densities greater than did fish from other areas of the watershed. Sockeye salmon captured in Chignik Lake, Chignik River, and Chignik Lagoon were only energetically different from one another based on age. Observed seasonal trends suggested juvenile sockeye salmon emigrate from Black Lake before the onset of winter due to forage and temperature limitations. A constant downstream migration occurred in the watershed during the summer, which suggested smoltification and osmoregulation processes in Chignik Lagoon fish
Alaska Energy Statistics 1960-2008
Prior to 1985, the federal Alaska Power Administration published the Alaska Electric Power Statistics. Then, the Alaska Energy Authority (formerly the Alaska Power Authority) began gathering statistical data and publishing this annual report. In 1988, the Alaska Electric Power Statistics report became a combined effort between the Alaska Systems Coordinating Council and the Alaska Energy Authority. Beginning in 1993, the report became a joint effort between the Alaska Systems Coordinating Council and the Alaska Department of Community and Regional Affairs, Division of Energy. After the 1995 report, no further reports were published until 2003 when a report was prepared by the Institute of Social and Economic Research (ISER), University of Alaska Anchorage (UAA), with funding provided by the Alaska Energy Authority (AEA), the Regulatory Commission of Alaska (RCA), and the Denali Commission.
This twenty-third edition of the Alaska Electric Energy Statistics was prepared by the Institute of Social and Economic Research. Information on utility, industry, and military electricity capacity, generation, and other characteristics was gathered primarily from reports filed with the U.S. Department of Energy (DOE), Energy Information Administration (EIA) and made available on their website. This was supplemented by data collected by the Alaska Energy Authority through the Power Cost Equalization (PCE) program and a limited number of direct contacts with electric power producers in the state. This is a similar methodology used to develop information for the 2003 report.Alaska Energy AuthorityIntroduction / Report Highlights / Electric Power Statistics / Alaska Railbelt / Alaska Renewable Energy / Alaska Energy Balance / Appendice
Effects of marine-derived nutrients on population dynamics of sockeye salmon (Oncorhynchus nerka)
Thesis (M.S.) University of Alaska Fairbanks, 2006The effects of marine-derived nutrients (MDN) on the productivity of sockeye salmon (Oncorhynchus nerka) stocks in Alaska were examined through nitrogen stable isotope analysis of smolts and mathematical models of the sockeye stock-recruit relationship. Smolt 8 [delta]šâľN was used to infer the degree to which smolts depend on MDN for their growth. We attempted to identify the characteristics of sockeye nursery lakes and watersheds that affect the availability of MDN to juvenile sockeye using multiple regression. Stock-recruit models incorporating MDN effects were fit to sockeye escapement-return data to test if fluctuations in sockeye stock productivity could be explained by changes in MDN input into nursery lakes. The magnitude of escapement and water residence time were the most important factors affecting the MDN availability to juvenile salmon. Mixing state of lakes and the distance from the coast were also found to significantly affect the MDN availability. We found that regional environmental fluctuations had a large effect on stock productivities in stock-recruit modeling. However, we did not find strong evidence to support our hypothesis that increases in MDN input to nursery lakes will result in increased productivity of sockeye stocks. Stock-recruitment data may be poorly suited to detection of the influence of MDN
The Pygmy Whitefish, Coregonus Coulteri, in Lake Superior
Bottom trawling by the U. S. Fish and Wildlife Service motor vessel Cisco in Lake Superior in 1952â1953 revealed a large population of a tiny whitefish, Coregonus (Prosopium) coulteri, which has been reported previously only from northwestern North America. The hiatus in range, from Lake Superior to the Columbia River basin, is the greatest known for a North American freshwater fish. Although minor structural differences characterize the disjunct populations of the pygmy whitefish, these are not deemed worthy of nomenclatorial recognition. Comparisons with related species indicate that the pygmy whitefish is distinctive in the small size, large scales, few vertebrae, few pyloric caeca, and in other characters.The pygmy whitefish is widely distributed in Lake Superior, especially in semiâprotected bays, such as Keweenaw Bay which yielded about 68 percent of the 1,623 specimens caught. The bathymetric range was 10 to 49 fathoms, with maximum abundance at the 25â to 39âfathom interval. Average length of fish increased progressively with water depth, chiefly because the number of yearlings declined from 100 percent at 10â14 fathoms to none at 45â49 fathoms.The average total length of pygmy whitefish caught by trawling was 3.4 inches (range 1.2 to 5.7). Extraordinarily slow growth was revealed by the examination of scales. Two fish from Keweenaw Bay, both nearing the end of their eighth growing season, were only 5.4 inches long. Compared to Keweenaw Bay, growth rate was about the same near Laughing Fish Point, faster in the Apostle Islands (and in Bull and McDonald Lakes, Montana), and slower in Siskiwit Bay, Isle Royale. Females grew more rapidly than males after the second year and had a longer life span.All male pygmy whitefish were mature at the age of 2 years and a total length of 3.6 or more inches. Most females were mature at 3 years and 4.2 inches; all older females were mature. Mean egg production was 362 (range, 93 to 597) per fish and 26 per gram of total weight for fish from 3.4 to 5.9 inches long. Spawning in 1953 occurred sometime in November or December.Crustacea (principally ostracods and amphipodsâcopepods in the young) occurred in 106 of 112 pygmy whitefish stomachs and made up 77 percent of the total food volume. When available, fish eggs appear to be important in the diet.Other coldâwater fishesâcottids, ninespine sticklebacks, smelt, and four species of coregoninesâwere the most frequent associates of the pygmy whitefish. Lake trout and troutâperch were also taken with it at the same stations or in the same trawl hauls. Its closest relative in Lake Superior, the round whitefish, was not an ecological associate.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/141996/1/tafs0161.pd
All-Alaska Rate Electric Power Pricing Structure
Economists at the Institute of Social and Economic Research, University of Alaska Anchorage were asked to research the potential options and impacts of establishing an All-Alaska Rate as an alternative to the current Power Cost Equalization (PCE) program funding formula. We were asked to provide a history of the PCE program and information on electricity rates and patterns of consumption across regions of Alaska. This report provides the results of this analysis.
Alaska is unique in many ways, including its consumption and pricing of electricity. There are large regional differences in consumption and prices that result from proximity to different types and quantities of resources. Differences in remoteness and population size also influence costs. Urban areas in the southern Railbelt benefit from larger economies of scale and access to natural gas and hydroelectric resources; the majority of hydroelectric facilities are located in Southcentral and Southeast Alaska. Most communities in rural Alaska depend on volatile and high price fossil fuels for the generation of electricity.
The Alaska statewide weighted average residential rate for electricity (17.6 cents per kilowatt (kWh) in CY2011) is higher than the U.S. average of 11.8 cents per kWh (U.S. EIA, 2012). Alaska now trails behind Hawaii (34.5 cents), New York (18.4 cents) and Connecticut (18.1 cents) based on ranking of average residential price per kWh. Hidden in the Alaska statewide average is considerable variation with some communities paying less than the national average and some paying considerably more.Senate Finance Committee, Alaska State Legislature.Executive Summary / Introduction / Review of Current Residential Consumption and Price of Electricity / Power Cost Equalization History / Electricity Rates and Levels of Consumption / Customer responsiveness to price changes / All-Alaska Rate / References / Appendix A.

Provenance and diagenesis of the Miocene Bear Lake Formation, Bristol Bay basin, Alaska
Thesis (M.S.) University of Alaska Fairbanks, 2010The Miocene Bear Lake Formation (BLF) is a prospective hydrocarbon reservoir exposed on the southwestern Alaska Peninsula, extending into the subsurface to the northwest (reaching 2,360 m maximum thickness). This study comprehensively characterizes composition of BLF sandstones, and develops important implications for varying reservoir quality. Unique integration of standard petrographic methods, electron microprobe analysis (EMPA), and â´â°Ar/ÂłâšAr dating of detrital hornblende strengthens interpretations by providing multiple lines of evidence and a more complete picture of composition, source units and terrane, and diagenetic history than possible with petrography alone. EMPA provides superior classification of volcanic rock fragments and identification of diagenetic minerals. Results indicate a pressure-controlled diagenetic system, and a provenance more complicated than recycling of older strata, as currently interpreted. Simultaneous derivation from the Meshik Volcanics and recycling of Tolstoi, Chignik, and Naknek formations suggests erosion of a structurally-deformed source terrain (e.g. reverse-faulted anticlines). Abundance patterns of pore-filling zeolites, calcite, albite, and kaolinite likely represent variations in Pcoâ caused by variations in burial depth. Optimal reservoir quality is likely present in the subsurface upper BLF along the northwestern coast (and deeper in the basin), where sandstone composition is presumably more quartz-rich, less volcaniclastic, and has experienced higher Pcoâ fluid migration.1.

Aspects of the Life History of the Pond Smelt (Hypomesus olidus) in the Yukon and Northwest Territories
The pond smelt (Hypomesus olidus) has a limited North American distribution, being restricted to the west coast of Alaska and the drainage of the lower Mackenzie River, N.W.T. This study examined an isolated population in a small tundra lake on the Yukon coastal plain. Otolith interpretation revealed that most adult fish sampled in Lake 100 were age 4+ and 5+ years, but a few individuals lived to age 8+ and 9+. Full maturity was not reached until age 5+ and repeat spawning was common. The sex ratio was skewed in favour of females. Growth was found to be slower in the Yukon population than in Alaskan and Japanese lakes. Some stunting was evident in Lake 100 pond smelt, but otherwise their meristic and morphometric characteristics corresponded with those from elsewhere. The pond smelt were primarily planktivorous in Lake 100 and there appeared to be no significant predation on them, but in the Mackenzie delta and elsewhere they are utilized as a forage species.Key words: pond smelt, life history, food habits, Hypomesus olidus, YukonMots clés: éperian à petite bouche, biologie, alimentation, Hypomesus olidus, Yukon, cycle vita
