Human Effects Analysis of the Multi-Species Framework Alternatives |
Section 5. Alternatives Analysis
The discussion below summarizes the effects of the alternatives, first by human effects category, then by human effects indicator. The purpose and meaning of human effects indicators were discussed in detail in Section 4.1.
The mix of strategies in each alternative varies by ecological province. This information was used explicitly for the EDT analysis of chinook salmon populations and costs of habitat measures. For hydrosystem actions, and facility modifications, each alternative includes specific actions and modifications provided by the Hydrosystem Workgroup.
The Framework alternatives would have a variety of social effects—some related and some unrelated to economics. The five human effects indicators in this category include indicators for health and human well-being, environmental quality, and other factors that affect the quality of life of citizens of the Northwest. Information about these indicators is closely tied to the results of the Ecological Workgroup analysis, which was not available when this Human Effects Analysis was prepared.
Table 5-1 provides a summary of
social effects of the alternatives.
| Table 5-1 | |
| Social Effects of Alternatives | |
| Significant decreased tribal poverty and mortality depending on status of natural stocks. Most potential for increased poverty associated with increased electricity costs, loss of transportation, and increased costs and reduced activity in natural resource industries. Most passive use value and environmental benefits from preservation and restoration, better quality of life in some rural communities, more stress and adverse construction effects in others. | |
| Largest increase in harvest potential, substantial decreased tribal poverty and mortality. Otherwise similar to Alternative 1. Some potential for increased flooding mortality. | |
| Large increase in harvest potential, substantial decreased tribal poverty and mortality. Otherwise similar to Alternative 1. | |
| Tribal poverty and mortality may decrease or continue, depending on future survival of hatchery fish. Low level of environmental benefits, little passive use values, little effect on mortality. High risk of extinction of some runs compared to 1, 2, 3 or 5. | |
| Large increase in harvest potential, some decreased tribal poverty and mortality. No loss of transportation economy. Otherwise similar to Alternative 1. | |
| Tribal poverty and mortality may decrease or continue, depending on future survival of hatchery fish. Low level of environmental benefits, little passive use value, little effect on mortality. High risk of extinction of some natural runs compared to 1, 2, 3 or 5 | |
| Tribal poverty and mortality may continue, depending on future survival of hatchery fish. Low level of environmental benefits, negative passive use value associated with natural fish, little effect on human mortality. High risk of extinction of some runs compared to 1, 2, 3 or 5 | |
Most impacts on poverty are likely to be related to unemployment, especially in natural resource industries: agriculture, forestry, and fisheries. Tribal poverty related to subsistence opportunities is a concern. Poverty rates may be affected by:
Mortality rates may be affected by several factors including:
Passive use values are discussed in Section 4.2.2 and in more detail in Appendix E. In summary, passive use values are potentially large economic benefits associated with healthier fish and wildlife populations. Positive passive use values associated with fish and wildlife protection are evidenced by public support for the ESA and the allocations of public funds for the protection and recovery of endangered species.
Passive use values for the Framework alternatives have not been quantified because (1) The available studies do not cover the range of population increases estimated for the Framework alternatives, (2) the available information about salmon does not differentiate hatchery and natural fish, (3) limited information is available about the values of some groups of Pacific Northwest residents, and (4) results of the available contingent valuation studies have not been verified by use of actual willingness-to-pay experiments. Several techniques have been suggested for verifying contingent valuation results, including better use of sampling and bias control techniques. However, as described earlier (Section 4.2.2), passive use values are probably the largest benefit potentially associated with Framework alternatives.
5.1.4 Other Environmental Effects
The only environmental benefits that have been estimated are for salmon populations and, from DREW: salmon and steelhead trout population increases from the breaching of the Lower Snake dams. Other environmental benefits will involve improvements in the status of other species of animals and plants. Many other environmental benefits should be included in the analysis (for example, water quality improvements, biological diversity) but cannot be quantified at this time because strategies have not been specified or impacts of the strategies have not been measured. Environmental benefits that are unrelated to fish and wildlife populations (that is, the multiple benefits of healthy ecosystems) are discussed in Section 4.2.
The alternatives also would have environmental costs. Alternatives that decrease hydroelectric power supply would be likely to cause an increase in thermal generation. This increase would contribute to fossil fuel emissions, including carbon. DREW analysis showed a small effect on fossil fuel emissions for Lower Snake drawdown alone.
Other factors that may affect the quality of life for residents include impacts on local populations, infrastructure, finance and social services, non-economic effects of construction, impacts on community and culture, and wealth effects that may not be picked up by other economic analyses. Alternatives 1, 2, and 3 may impair quality of life for natural resource occupation workers in rural communities, at least in the short run. Alternatives 4, 5, 6, and 7 may impair quality of life for tribal members, fishermen, and river-based recreationists. No quantitative information has been developed.
Community effects stem from disruptions to established local norms of work and behavior. Some habitat strategies might result in disruptions to established resource use patterns and property rights. Some alternatives might reduce these effects by use of more incentives.
Additional tribal effects are human effects indicators of concern to Tribes above and beyond those human effects indicators discussed earlier in this document. Tribal members have unique concerns (identified for the Human Effects Workgroup by participants reflecting tribal perspectives) that transcend their roles in the non-tribal economy. This section covers some of these concerns.
Given the broad cultural and spiritual relationship between Columbia Basin natural resources and tribal peoples, it is likely inappropriate—and also not fully possible—to establish linkages between Framework alternatives and the circumstances of tribal peoples based on some single calculus or measure. Information is adequate, however, to distinguish between Framework alternatives, based on three inter-related bodies of information available to this report:
Estimates of changes in numbers of
chinook salmon in the Framework alternatives from the EDT analysis are provided
in Table 5-2. Estimates for other salmon species are not currently available.

The EDT results suggest that all of the alternatives would provide more natural salmon than alternative 4. This finding rests on numerous assumptions about survival of natural and hatchery fish that have not been reviewed or approved outside of the Ecological Workgroup. Therefore, these results are not yet accepted as the basis for analysis of tribal effects. Rather, results from PATH used for the Feasibility Study are considered.
The Feasibility Study provides fairly extensive data about breaching Ice Harbor, Little Goose, Lower Monumental, and Lower Granite dams on the Lower Snake River, but little information is provided about other Framework strategies.
PATH (1998) studies found that breaching Lower Snake and John Day reservoirs would increase fish populations and increase the chances of meeting NMFS jeopardy standards. NMFS (1999) finds that "based on the PATH analyses conducted to date, actions involving drawdown (Feasibility Study alternatives A3 and B1) projected consistently higher relative probabilities of exceeding survival and recovery population thresholds than actions using the current configuration… ." These studies support the biological benefits of breaching strategies independent of their role in the Framework alternatives.
Assessment of tribal impacts from the alternatives posed also depends critically upon whether it is assumed that populations of key fish and wildlife species, and more broadly, Columbia Basin ecological diversities in general, are stable, or whether they are in continued decline (Section 5.5). Historically, it has been demonstrated that tribal life has been devastated by cumulative destruction of the salmon-producing capabilities of the Columbia-Snake system and by declines of many game and plant species upon which they depend. Much of this destruction has been accompanied by mitigative assurances which, with time, turned out to be hollow promises. As a result of this empirical record, the Tribes have learned to be cautious of promised mitigation. That concern carries to the present assessment—where the Tribes see little in Framework Alternatives 4 through 7 to indicate that these long-term cumulative losses to key species will be reversed. Because of these concerns, summary results in this section first will be presented under the tribal assumption that key stocks are still under threat and will continue to decline unless major remedial actions are quickly undertaken. We will then summarize results using a stock stability presumption, for comparison with other like sections of this report.
The Tribes used PATH results
refereed by independent experts to estimate comparative tribal harvests from
breaching the Lower Snake River dams, and compared these to harvests forecast
under "status quo" and under an alternative termed "the
transportation alternative," which maximized potential retrofitting of fish
passage measures at these dams. Probabilities of removal of natural
spring/summer chinook from the Endangered Species List after 48 years of
recovery are presented in Table 5-3.

Considering these data, several conclusions seem evident with respect to impacts on Tribes.
As with salmon, available information about habitat and dependent fish and wildlife awaits the completion of work by the Framework Ecology Workgroup. That work also may specify impacts on several potential key species of interest to Tribes, notably, bull trout, beaver, and bear, and provide further information about salmon. Preliminary information from the Framework process suggests the ranking of habitat recoveries under framework actions shown in Table 5-4.
Additional information is available
for impacts on the Nez Perce, Yakama, and Umatilla Tribes if the reservoirs for
the four Lower Snake River dams were drawn down to "natural river" by
breaching. This information is summarized in Table 5-5.

| Fishing sites | Access to many fishing sites preempted. Some alternative sites available (principally non-salmon). | Would reestablish tribal fishing sites along 150 miles of river. |
| Hunting and gathering areas | Reservoirs presently flood 33,890 acres. | Up to 33,890 acres restored for tribal hunting, gathering of roots, berries and plants. |
| Tribal land base | Eliminated 33,890 acres from tribal use. | Would add land-based tribal opportunities up to 1/3 the size of present Nez Perce land holdings, or, up to 1/5 the size of present CTUIR land holdings. |
| Cultural activities | Floods more than 600 to 700 locations where cultural activities occurred. | Would enable tribal peoples to reestablish contact and use of more than 600 to 700 usual cultural locations. |
| Religious/spiritual | Floods numerous tribal graves. Involved violation and stealing of bodies of some ancestors. Separates tribal peoples from their land, their rivers, and their sacred and ceremonial places. | Would reunite tribal peoples with their land, the river, and the creatures of the Lower Snake. Would allow Tribes to care for the graves of loved ones. Would recover sacred and ceremonial places. |

The tribes place great importance on cool, free-flowing, pollution-free streams and rivers to support humans, fish, and wildlife. Framework Alternatives 1, 2, and 3 breach Lower Snake dams, and presumably would improve water quality as a result. Alternative 5 explicitly targets adequate summer temperatures for fish, and should lead to improved water temperatures in the system. Conversely, alternatives that continue adverse discharges (toxic or non-toxic) into Columbia Basin waters will rank low with respect to water quality. Our analysis awaits further information.
5.2.5 Distribution of Columbia Basin Income and Wealth
Historically, the Tribes of the Columbia Basin have been deprived of the resource wealth required for their survival, even though protection of these tribal resources was promised by representatives of the United States and often were guaranteed in treaties. Non-Indian residents of the Columbia Basin obtained these tribal resources by force, coercion, negotiation, and in later periods, by conversion of rivers to support great amounts of electric energy production, irrigated agriculture, and commercial transportation, but far less fish and wildlife. So as most residents of the region have prospered, the circumstances of tribal peoples have become increasingly desperate. These circumstances and their result for tribal peoples are summarized in Section 3.2.2.
Tribes are consequently critically interested in the issue of fairness—whether alternatives considered by the Framework solidify these prior takings of wealth from the Tribes, and the imbalances of poverty, unemployment, income, and ill health they created between tribal peoples and regional residents in general. Such concerns about distributional fairness also are mandated under the EPA’s Environmental Justice Guidelines.
Based on discussion in this report, it appears that Framework Alternatives 1 through 3 would move the region toward a fairer balance between the wellbeing of tribal and non-tribal citizens. It is not clear that Alternatives 5 through 7 would achieve this objective. Alternative 4, by recommending "status quo and study" would continue present adverse levels of poverty, unemployment, insufficient income, and premature death for tribal peoples of the region.
5.3 Economic Efficiency Effects
Economic efficiency effects are meant to provide some of the information required for NED accounts, which are most commonly encountered in the context of benefit-cost analysis. The accounting stance for NED analysis is usually the entire nation, or all U.S. citizens. Cost measures also could be used in the context of cost-effectiveness analysis.
This human effects indicator includes economic surplus associated with commercial harvest of salmon. Other fish species that may be impacted have little or no commercial importance. Recreational harvest is included in the discussion of the recreation industry (Section 5.3.3) and subsistence harvest is included in tribal effects under the salmon human effects indicator (Section 5.2.2).
Producer surplus in commercial fisheries involves sales, costs, and net returns. Sales are the price of fish times quantity sold. Costs are payments for labor, services, and equipment. Net returns, or sales minus costs, are a measure of economic benefit. Costs must include the opportunity costs of unpaid factors for benefits calculations. The analysis does not include consumer surplus of fish consumers in the United States. Consumers of salmon are not likely to be affected much because in a world market for salmon (much salmon is commercially cultivated), the price of salmon would not be affected much by Columbia River actions.
The specific strategies for chinook salmon included in the preliminary EDT analysis are:
Short-run harvest reductions, though not currently specified by any alternatives, may be required. The analysis assumes that harvest reductions are accomplished by positive voluntary incentives so that owners of fishing enterprises are not worse off. By assumption, ratepayers would pay the costs of these voluntary incentives.
Table 5-6 summarizes the available information about impacts of the alternatives on fisheries. Sources of information were discussed in Section 4.5.
Important uncertainties in
estimating fisheries impacts involve fish population increases and future
fisheries regulations. Critical assumptions involved in estimating fisheries
impacts involve U.S. v. Oregon and the Pacific Salmon Treaty. The NMFS currently
is considering salmon harvest alternatives in the West Coast Salmon
Environmental Impact Statement ranging from status quo to no harvest. A
reasonable range of common assumptions might include more restrictive harvest
regulations. If more restrictive harvest regulations were adopted as a common
assumption, the effect would be to minimize the adverse effects of the Framework
harvest strategies.
| Table 5-6 | |
| Impacts of Alternatives on Commercial Fisheries | |
| Most ocean harvest eliminated in the short run, share of harvest from ocean substantially reduced in the long run. Harvest increase in the long run. Potential benefit compared to current conditions is about $0.6 million to $2.4 million annually. Change in type of harvest to live catch, terminal stock, and known-stock techniques. Most lower river harvest eliminated in its current form. | |
| Ocean harvest reduced in the short run, share of harvest from ocean reduced in the long run. Most harvest increase in the long run. Potential benefit is about $2.7 million to $10.0 million annually, mostly on mainstem. Change in type of harvest to live catch, terminal stock, and known-stock techniques. Population aggregate escapement goals. As a goal, harvest increased in the long run to levels defined by U.S. v. Oregon. Some cost savings through more efficient harvest; but increased costs for management and tagging. . | |
| Similar to Alternative 2. Potential benefit is about $2.5 million to $9.0 million annually. | |
| Status quo harvest rates. Potential benefit is about $1.0 million to $3.4 million annually. No selective harvest. Weakest aggregate harvest rate. Long-run effects depend on experimental management. | |
| Similar to Alternative 2. Potential benefit is about $2.4 million to $8.7 million annually. | |
| Most ocean harvest eliminated in the short run, share of harvest from ocean reduced in the long run. Potential benefit is about $1.2 million to $4.5 million annually. Some change in type of harvest to live catch, terminal stock, and known-stock techniques. Selective fisheries, weakest aggregate harvest rate, and aquaculture development. Most lower river harvest eliminated in its current form. | |
| Similar to Alternative 6. Potential benefit is $0.8 million to $2.9 million annually. | |
This human effects indicator includes economic measures of hydropower costs and benefits. Hydropower production is affected by several strategy blocks, including dam breaching or construction, dam modifications, and dam operations and flow management. The value of sales also is affected by operations that change the timing of production. In addition, hydropower costs are increased by the share of other costs (mostly habitat, harvest, and hatcheries) assigned to hydropower.
The Human Effects study team has assumed that ratepayers (electricity consumers) pay for the costs of electricity needed to replace lost hydropower, and that ratepayers must pay for harvest reductions, hatcheries, and one third of habitat costs. Demand may be more elastic in the future as market conditions change, and this may reduce the ability to pass on these costs.
Table 5-7 summarizes the available
information about impacts of the alternatives on hydropower. The analysis
involves electricity producers in two ways—BPA sales are reduced, and other
costs are increased. BPA customer costs are increased by the cost of replacement
power and the other costs are passed to ratepayers. On the other hand, thermal
power producers and construction interests may benefit from the need for new
capacity. These benefits are reflected in the regional assessment.
| Table 5-7 | |
| Impacts of Alternatives on Hydropower | |
| Hydropower value losses from dam breaching, modifications, and operations totaling about $590 million annually and additional transmission costs are about $20 million. Additional increase in ratepayer costs for implementation and preliminary habitat costs. Implementation costs such as breaching may cost $290 million in annualized terms. Facility modification costs about $80 million annually, but no O&M for breached facilities. Preliminary habitat cost share (1/3 of habitat costs) from $120 million to $220 million annually. With this magnitude of additional net costs, potential problems for BPA meeting financial obligations. Cost savings from non-operation of facilities are about $54 million. Long-run cost savings from eliminated hatchery production are $35 million to $50 million annually. | |
| Hydropower value losses from dam breaching, modifications, and operations totaling about $320 million annually and additional transmission costs are about $20 million. Additional increase in ratepayer costs for implementation and preliminary habitat costs. Implementation costs such as breaching may cost $190 million in annualized terms. Facility modification costs about $110 million annually, and O&M at affected facilities $10 million. Preliminary habitat cost share (1/3 of habitat cost) from $50 million to $90 million annually. O&M cost savings from non-operation of facilities are about $44 million. Some likelihood of financial problems for BPA. New hatcheries cost $1.4 million annually. | |
| Hydropower value losses from dam breaching, modifications, and operations totaling about $250 million annually, and additional transmission costs are about $20 million. Increase in ratepayer costs for implementation and preliminary habitat costs. Implementation costs such as breaching may cost $60 million in annualized terms. Facility modification costs about $110 million annually, and O&M at affected facilities about $20 million. Preliminary habitat cost share from $50 million to $90 million annually. O&M cost savings from non-operation of facilities are about $34 million. Some likelihood of financial problems for BPA. New hatcheries cost $2.4 million annually. | |
| Small changes in hydropower value from removal of a few small dams, but comparable cost savings. Facility modification costs are about $30 million annually, O&M is about $54 million annually. Long-run effects unknown. New hatcheries cost $0.4 million annually. | |
| Hydropower value loss of about $60 million annually. Facility modification costs are about $35 million annually, O&M is about $54 million annually. Cost shares for preliminary habitat are $60 million to $100 million annually. May be more costs for selective harvest. New hatcheries cost $4.0 million annually. | |
| Increase in hydropower value of $20 million to $40 million annually. Facility modification costs are about $26 million annually, O&M is about $54 million annually. Cost shares for habitat are $40 million to $60 million annually. May be more costs for selective harvest. New hatcheries cost $5 million annually. | |
| Increased hydropower value of about $250 million annually. Facility modification costs are about $23 million annually, O&M is about $54 million annually. Cost shares for preliminary habitat are $10 million to $20 million annually. Change in hatcheries saves $0.8 annually. May be more costs for selective harvest. | |

This human effects indicator includes producer and consumer surplus from all forms of recreation that may be affected by the alternatives. Important categories of recreation include:
Table 5-8 summarizes the available
information about impacts of the alternatives on recreation.
| Table 5-8 | |
| Impacts of Alternatives on Recreation | |
| Loss of flatwater recreation in Lower Snake, McNary, and John Day reservoirs, increase in river-based recreation. Net effect for Lower Snake breaching believed positive, for John Day believed small, unknown for McNary. Improved salmon and steelhead trout fishing and riverine opportunities. Increase in sport fishing value compared to current conditions for salmon about $2 million annually. Increased steelhead trout populations and value unknown, could be large. Other outdoor recreation increased in amount and quality. Road closures and other loss of access on public lands may have costs and benefits. Some new access to acquired habitat areas assumed. | |
| Loss of flatwater recreation in Lower Snake and John Day reservoirs. Benefits and losses at least as large as Alternative 3. Net benefit of John Day drawdown (net value of change in recreation types) not expected to be large based on John Day drawdown study. Increase in sport fishing value compared to current conditions for salmon about $5 million annually. Increased steelhead trout populations and value unknown, could be large. | |
| Lower Snake reservoirs removed. Loss of existing sport fishing value about $2 million annually. Increase in sport fishing value compared to current conditions for salmon about $4 million annually. Increased steelhead trout populations and value unknown, could be large. Loss of other flatwater recreation values about $30 million annually, increased riverine recreation valued between $85.5 million and $366 million annually. Other outdoor recreation values increased depending on management of acquired and restored habitats. Habitat-related effects similar to Alternative 2. | |
| Recreation patterns on Lower Snake largely unchanged. Potential flow augmentation from Snake River in long term would cost $4 million to $14 million annually, primarily in Idaho, due to reservoir drawdown. Increase in sport fishing value compared to current conditions for salmon about $3 million annually. Increased steelhead trout populations and value unknown. | |
| Not much net effect, some gains and losses from habitat measures. Increase in sport fishing value compared to current conditions for salmon about $4 million annually. Increased steelhead trout populations and value unknown, could be large. | |
| Not much effect. Increase in sport fishing value compared to current conditions for salmon about $1 million annually. Increased steelhead trout populations and value unknown. | |
| Not much effect. Increase in sport fishing value compared to current conditions for salmon about $1 million annually. Increased steelhead trout populations and value unknown. | |
This human effects indicator includes producer and consumer surplus in the navigation industry, its customers, and rail and trucking industries. Impacts occur only in alternatives with breaching. Transportation is shifted to truck and rail. The economic cost is the difference in resource costs between the two transportation modes. Most of the freight is agricultural products and supplies. Agricultural demand is elastic, so most cost would be paid by agricultural transportation users.
Table 5-9 summarizes the available
information about impacts of the alternatives on transportation. Important
uncertainties involve the ability of agriculture to absorb the transportation
cost increases and the market structures in barging, rail, and trucking that
affect the costs of transportation. Improvements in rail and road transportation
might be beneficial for regional residents.
| Table 5-9 | |
| Impacts of Alternatives on Transportation | |
| Navigation lost above John Day dam. Most shipments would probably shift to rail to/from Portland. Navigation net revenue loss and transportation cost increase may be $90 million to $100 million annually. Most cost increase passed to agriculture in the Upper Columbia Basin. Transportation cost increases would cause some marginal dry cropland probably to go out of production. | |
| Same as Alternative 1. | |
| Loss of navigation from Idaho to Tri-cities. Without breaching, cost of navigation is about $225 million. With breaching, cost for rail and trucking increases to about $250 million. Therefore, net cost increase is about $25 million. Most of the cost increase is passed to agriculture in the Upper Columbia. | |
| No effect in the short run; unknown in the long run. | |

| No effect. | |
2. Habitat and hydrology strategies that reduce irrigation withdrawals to leave more water in-stream would require reductions in the amounts of water used for irrigation. Costs would be required for increased irrigation efficiency, or irrigated land use would be changed. Costs could be up to $100 million annually in Alternative 1; near $30 million annually in Alternatives 2, 3, or 5; and minimal in Alternatives 6 and 7. By assumption, these costs would be borne by ratepayers, and taxpayers. By assumption, electricity ratepayers would pay about one-third, taxpayers two-thirds, so he share paid by farmers would be zero or minimal.
5. Some strategies would acquire agricultural land and devote it to conservation uses.

| Impacts of Alternatives on Agriculture and Water Users1 | |
| Cost to
maintain 167,000 acres irrigated from John Day, 125,000 acres from
McNary and 37,000 from Ice Harbor would be up to $60 million annualized.
Agriculture also would pay up to $27 million annually for screening
costs.
Preliminary habitat costs on agricultural lands would be $140 million to $300 million annually. These costs are assumed to be paid by some mix of farmers, ratepayers, and taxpayers.

This human effects indicator includes the direct costs of implementing major changes to land use on forested lands in the Columbia Basin. Forestry-related strategies would change forestry practices and reduce timber harvest. Table 5-10 shows potential impacts from the preliminary habitat assessment. In Alternative 1, added costs for restoration and management on forestlands could be $70 million to $130 million annually in costs and net revenue losses. Annual costs in Alternatives 2, 3, and 6 are similar at about $20 million to $60 million annually. Alternative 5 forestry costs amount to about $40 million to $70 million annually, Alternative 4 would cost $5 million to $10 million annually, and Alternative 7 would have little effect on forestry.
Most of these costs represent changes to forestry practices on private lands that would be compensated. Costs on federal lands would be minimal because a relatively small amount of federal land is being harvested in the region. One exception is that costs to establish normative fire conditions on federal lands could be large. Restoration and management costs on federal lands are assumed to be paid by federal taxpayers, but increased harvest costs on federal lands probably would be paid by users, not taxpayers.
This category of effects considers all of the industry-level effects combined, plus the effect of trade linkages, on important indicators of regional economic activity. These indicators are the value of output, personal income, and employment. These human effects indicators are discussed in Section 3.2.4, as are some issues about the meaning and application of these measures.
The DREW regional analysis suggests that a substantial amount of temporary employment and income would be created by breaching the Lower Snake River dams. Total temporary construction employment would be about 5,500 jobs in power plant construction; and about 15,000 jobs in construction of new transmission lines, rail, highways, facilities, pump stations, and wells. In the long run, and permanently, about 3,000 jobs would be lost due to loss of irrigated agriculture and cessation of dam operations, but 2,300 jobs would be gained from power plant operations and increased recreation use (USACE, 1999h).
The Feasibility Study did not include economic impacts of the loss of the navigation industry or the job gains from increased sales to the rail and trucking industries. Estimates of navigation-related losses were developed by the Tri-Port Economic Impact Study (1997). Roughly 800 jobs would be lost in the navigation sector, 800 more jobs would be lost in related sectors, and about 3,000 jobs would be lost in industrial parks and related areas. No data are available about the offsetting increases in rail or trucking.
The Feasibility Study estimated sales, income and job losses that might be caused by increased electricity ratepayer costs following breaching of the Lower Snake dams. Over the entire four-state region, lost sales amount to about $400 million annually, more than 2,300 jobs would be lost, and more than $230 million of personal income would be lost. The regional analysis for the human effects analysis uses input-output (I-O) to estimate changes in the value of output, personal income, and employment. The use of I-O requires that several issues regarding the method be discussed.
I-O analysis estimates changes in output, income, and employment following a change in sales from the regional economy. These sales, called final demands in I-O terminology, cause additional rounds of sales in the regional economy, giving rise to the familiar economic multiplier effect.
I-O assumes constant returns to scale. As the scale (amount) of production increases, costs increase proportionately. If all individual operations are the same, and assuming perfect competition, I-O may imply that no economic surplus is associated with increased sales (output). This inference about producer surplus effects may not be true, however, if the regional technology differs from the total market technology such that the local economy has comparative advantage that generates economic rents, even if the local industry exhibits constant returns to scale.
I-O does not count amounts of regional resources used in production, yet it implies that resources are available to meet increases in demand according to the fixed-input technology. In fact, regional resources may not be available to meet increases in demand, and the necessary resources may need to be imported. This is one reason why changes in output, income, and employment are measures of regional activity, not necessarily benefits or costs to the region.
Changes in regional economic activity may have profound effects involving substitution among factors of production and/or price changes. I-O does not consider either of these economic phenomena.
Transfers of funds among industries, households, or other members of the regional economy generally have offsetting effects in that the increased rounds of expenditure at the receiving end are offset by decreased rounds of expenditure at the giving end. This principle is important to the Human Effects Analysis because most costs would be paid by regional residents.
Effects that are offsetting for the region as a whole may have important local implications. One goal of this analysis is to identify particular groups of people who may be most affected by the alternatives. Ideally, the human effects indicators could be applied to any group of people that may be affected. Due to data limitations, measures are possible only for specific geopolitical areas, such as counties, states, or groups of counties.
Economic multipliers measure direct effects and effects that occur through backwards trade linkages—the purchases of goods by consumers and production inputs by producers. Practical considerations also limit the extent to which forward linkages, price effects, wealth, and public services effects can be quantified.
Tables 5-11 through 5-14 provide an example of human effects estimates of major regional impacts by alternative. This example uses the economic coefficients and multipliers developed by the DREW regional analysis with direct economic effects estimated for the human effects analysis to estimate regional effects of the Framework alternatives. No positive fish and wildlife benefits are included in the example. Rather, the example counts payments and expenditures required to implement hydrosystem, facilities, and habitat strategies. The example is illustrative and preliminary.
Table 5-12 shows the direct economic effects included in the regional analysis. The direct effects are based on an earlier version of the Human Effects Analysis but are still similar to the values shown elsewhere in this final report. Some important assumptions are:
