INTRODUCTION AND SUMMARY OF RESULTS A. Introduction Champion International Corporation owns and operates a paper mill at Canton, North Carolina that is sited on the Pigeon River. The mill is about 37 miles upstream of the Tennessee and North Carolina border. The United States Environmental Protection Agency (USEPA) has proposed an NPDES permit for the mill that would significantly reduce the amount of color allowed to be discharged from the mill into the Pigeon River. One of many submissions in this permit proceeding was a report by Bach and Barnett entitled, An Economic Impact Analysis on the Recreational Benefits of a Restored Pigeon River (see Reference [1]). This study concluded that levels of reduction consistent with the April 1987 USEPA proposal permit would be economic. In December 1987, USEPA published a second proposal which limited color discharges even more severely than the April proposal. At the request of Champion, National Economic Research Associates, Inc., an economic consulting firm specializing in energy and environmental economics, evaluated the economic impacts of three color reduction strategies and also reviewed and evaluated the Bach and Barnett report. First, we estimated the benefits and costs under three strategies proposed to reduce color discharges from the Champion mill. One of the plans was proposed by Champion; two were proposed by USEPA. The most stringent plan (i.e., the December proposal by USEPA) would certainly lead to plant shutdown. The less stringent USEPA plan would likely cause plant shutdown. All the plans had costs significantly greater than benefits, and both USEPA plans would have substantial unemployment impacts. However, Champion's proposal yielded benefits that were closest to cost and exhibited small net gains in employment. Second, based on our review and evaluation of the Bach and Barnett n/e/r/w -2- analysis, we have concluded that there were several fundamental errors that completely undermine their conclusion that substantial reductions in color discharges could be justified on economic grounds. B. Summary of the Economic and Employment Impacts of Reducing Color Discharges from the Champion Mill Table I summarizes our results. This table assumes that Champion would take all actions technologically feasible to keep the plant open. The plan proposed by Champion would reduce color discharges from the mill by 50 percent on a long- term average basis. The costs associated with this program would be $38.4 million. This is the present value of the costs over a 10-year period expressed in 1988 dollars. These costs would be over three times the benefits of $11.3 million. Thus, an expenditure of one dollar achieves only 30 cents in benefits. The two USEPA proposals would remove more color from the effluent discharge but at substantially higher costs. Also, costs would exceed benefits by a far greater margin than under Champion's proposal. Under the less stringent of the two, which would consistently achieve less than 50 color units in the Pigeon River at the Tennessee border, the cost would be $164.5 million, with corresponding benefits of only $18.0 million. This results in a benefit of 11 cents per dollar of expenditure. The more stringent proposal, contained in the second draft USEPA permit, would limit discharges at the mill to 50 units of color. This proposed effluent limit cannot be achieved with current technology and therefore would require that the mill be shut down. The direct cost of this proposal would then be the cost of building and operating a new facility in a different region net of any operating and maintenance savings attributable to the new investment. We have estimated these costs at approximately $290.0 million. The benefits under this program would be $18.3 million. Thus, for every dollar of expenditure, this plan would yield benefits of about one cent. These cost estimates do not include the Tlih/I'ra -3- substantial economic and social cost impacts on the city of Canton, western North Carolina or eastern Tennessee. There are several reasons for the striking divergence between costs and benefits. On the benefit side, only the relatively small stretches of the Pigeon River which are immediately downstream of the Tennessee border have good recreational potential. The whitewater rafting run of five miles is comparatively short. The river is usable for rafting only when the `hydroelectric electric generation demands at the Walter's Lake plant of Carolina Power and Light (CP&L) result in adequate releases. Also, other factors unrelated to color tend to make the river less attractive: the most scenic part of the river in North Carolina has virtually no water in it at all and is not affected by color discharges from the mill because of the CP&L water diversion tunnel; and low summer river levels, particularly in North Carolina, restrict its suitability for most recreational activity. On the cost side, the plant is already a low color producer in terms of pounds of color effluent per ton of product. The incremental removal of color requires increasingly more expensive and untested methods. The low river flows make the achievement of the lowest level of color impossible without a complete shutdown of the mill. Employment is another measure of the impacts of the discharge reduction plans. The Champion proposal would increase recreational-related employment in Tennessee by 77 jobs. The other two plans would see net recreational employment increases of about 123 jobs. Based upon U.S. Department of Commerce figures, the 50 percent reduction plan would increase the number of jobs in North Carolina by 176 jobs. If the mill were to shut down, as would be required under the USEPA December proposal and would be likely under the earlier proposal, the loss of employment in North Carolina would total over 12,000 jobs, with an added loss in nle✓rlw 4- Tennessee of over 800 paper-related jobs. Thus, under either USEPA proposal, Tennessee would experience a net loss of almost 700 jobs. C. Evaluation of the Bach and Barnett Analysis Bach and Barnett estimate the direct and indirect recreational benefits from reducing color discharges from the Champion mill to meet 50 color units at the state line and the costs of achieving these benefits. Based on their analysis, they conclude that reducing the color discharges to that level is justified on economic grounds. We have reviewed and evaluated their analysis and found it to be seriously flawed. There are several key errors that cause them to incorrectly conclude that the level of color reduction they evaluated would be justified on economic grounds. They have failed to discount benefits and have overstated and miscalculated indirect economic benefits. In addition, they have utilized company- wide rather than plant-specific data to evaluate local impacts. D. Organization of the Report The remainder of the report is divided into five sections. Section II describes the calculation of benefits. Section III discusses the costs of each plan. Section IV compares the costs and benefits. Section V calculates employment impacts. Section VI evaluates the Bach and Barnett analysis. II. BENEFITS This section discusses how the benefits from reducing color discharges into the Pigeon River are calculated. We begin by describing our overall approach. This is followed by a discussion of our estimates of the benefits from greater recreational use and improved property value on the assumption that color discharges are eliminated entirely. We then determine the benefits associated with each of the color discharge reduction programs we evaluated. The section concludes ia/ea'ao -5- with a discussion of other possible sources of benefits--option values and existence values. A. Overall Aonroach There are two issues regarding the relationship between reductions in color discharges into the Pigeon River and improvements in recreational benefits and property values. First, it is not clear to what extent reductions in color discharges from the Champion mill would be perceptible in the river. It is even less clear that incremental improvements, say from 100 to 50 units on average, would be noticeable in the river. Second, even if these changes were noticeable, there is no direct evidence that they would affect either recreational activity or property values. Bach and Barnett allege, however, that color levels in excess of 50 units reduce the attractiveness of the Pigeon River for recreational uses (whitewater rafting in particular) and may also reduce property values for land adjacent to the river. It is important to note that these supposed adverse effects are entirely hypothetical. Despite an extensive review of the literature we can find no empirical studies which relate color to recreational activity. Indeed, we have limited evidence for certain naturally very dark rivers (the Androscoggin River in Maine for example) on which whitewater rafting and fishing are quite popular activities. While there is some limited support in the economic literature for a relation between color and property values, this may simply reflect the statistical association between color and other unrelated aspects of water quality. Despite our reservations about the actual impacts of reducing color effluents, for the purposes of this study we have adopted Bach and Barnett's thesis and have assumed that color reduction will enhance recreational activity and rL4EV /W -6- property values on the Pigeon River and have attempted to quantify the maximum possible impacts of color changes. The time available for this study has made a direct investigation of the Pigeon River infeasible. Consequently, we have relied on data for other rivers to estimate the benefits from reducing color discharges into the Pigeon River. In our effort to transfer other results to the Pigeon River we have always allowed for the maximum benefit potential. The actual benefit levels are quite likely to be lower. Several recreational activities are feasible on the Pigeon River, including whitewater activities (rafting, canoeing and kayaking), floating (primarily rafting although it includes "inncrtubing," canoeing and kayaking), fishing and general sightseeing. To calculate the increase in usage for these activities in the absence of color effluent we used estimates of current usage on Tennessee rivers in the vicinity with no perceived elevated color levels, particularly the Ocoee and Hiawassec Rivers. Adjustments must be made to these estimates since these rivers are different from the Pigeon River in respects other than color. To estimate the value of a visit we have utilized a variety of published sources. For the most part, they are the results of contingent valuation studies. In these studies participants in an activity are asked to estimate the value of that activity to them in excess of the costs incurred. These estimates, known as consumer surplus, serve to define the value of a day. Bach and Barnett also employ consumer surplus valuation. Multiplying the value per day by the increased number of days gives our estimate of benefits from reducing color discharges. Property value benefits presumably derive from scenic advantages of being along a river of reduced color as well as the enhanced levels of wildlife and recreation the river can support. Several studies [2,3,4] have related color and general water quality to property values along coastlines and lakefronts. We have n/e/ram -7- calculated current values of river-front property along the impacted portion of the Pigeon River and have used these studies to estimate the increase in property values attributable to a river with no added non-natural color. B. Rafting and Floating Whitewater rafting is feasible on a 4.5 mile stretch of river about 37 miles below the Champion mill--from River Mile (RM) 26 at the CP&L powerhouse to RM 21.5 in Hartford, Tennessee (see Figure 1). As recently as last summer, a commercial supplier offered whitewater rafting trips on this stretch. The river below this point has too low a gradient to support whitewater rafting, while over the 37 miles between the mill and the power plant, both the gradient of the river and the volume of water are insufficient to support rafting. Rafting on the Pigeon River is further limited for two reasons. First, the climate is conducive to rafting only from April to October. Second, during this period rafting is limited to periods of discharge from the CP&L power plant. When the plant is not operating (or is operating only one of its three turbines) the depths are insufficient to support rafting. CP&L's obligation as a public utility is to generate power so as to minimize electric generation costs without regard to potential rafting activity. However, for the purposes of this study we have assumed that CP&L generates electricity during as many daylight hours as water levels in Walter's Lake permit during the rafting season. The relatively short length of the Pigeon River run makes whitewater rafting less attractive than it would be on longer rivers. First, no more than a half-day trip is possible, while other rivers offer full day trips. Second, since congestion limits the number of potential rafters per mile, shorter rivers will have lower capacities. . -8- To estimate the number of potential whitewater rafting trips for the Pigeon River we used data for the Ocoee River, which is the closest comparable river to the Pigeon River. The whitewater rafting portion of the, Ocoee River, like the Pigeon River, is five miles long, allowing only half-day trips. In addition, it is also dam-constrained. Total usage on the Ocoee River for 1987 was about 120,000 visits [5]. Following Bach and Barnett, we take this figure as a limit to usage on the Pigeon River. We assumed that there is no current recreational usage on the Pigeon River and that over five years usage for whitewater activities would rise to 120,000 visits per year. Thus, we have assumed that all recreational use of the Pigeon River would be attributable to reductions in color discharges. This obviously tends to overstate the benefits from lower discharges, since there is currently recreational usage of the river. The attached brochure (Figure 2) illustrates the recreational benefits of the Pigeon available today. These visit estimates are displayed in column (1) of Table II. To estimate the value for a rafting day we used a study conducted in Colorado in 1978 [6]. This study found that the consumer surplus from a whitewater rafting trip averaged $10.94 per person per day. Once again, this represents the difference between what people would be willing to pay and what they actually had to pay for a rafting trip. The estimate was made by eliciting from rafters the amount of money in addition to what they had paid that day that would cause them to forego that trip on these rivers. Converting this value to 1988 dollars, we find that the benefits are $19.28 per tourist day. Other whitewater activities, for example, kayaking and canoeing, had similar values. The equations from which these estimates were drawn show consumers to be quite sensitive to congestion on the river. Since congestion levels on the Ocoee n/e✓r/W -9- River are much higher than those observed in Colorado, we have lowered our estimate to $13 per trip. In addition to the five-mile stretch of whitewater between the power plant and Hartford, there is a more placid stretch from RM 21.5 to RM 16.5 on which floating is feasible during periods of higher water. On this stretch the river resembles the Hiawassee River. We have estimated floating usage for the Pigeon River based on data for the Hiawassee River. While this activity may be expected to be constrained somewhat by power generation, water levels further downstream are less affected by dam activities because of the lower gradient. Nonetheless, river levels are probably too low to achieve any significant recreational activities in August or September. Given that these months generate 35 percent of noncommercial activity, we have reduced the Hiawassee River floating usage of 80,000 visits [7] by 35 percent to 52,000. Unlike whitewater rafting, which has been growing at about 6 percent per year on the rivers for which we have visitation data over time, floating activity seems to be on the decline. On the Hiawassee River, usage has been declining by about five percent per year since 1978. In estimating floating usage for the Pigeon River, we have conservatively assumed no decline. Again, we assumed growth to capacity would occur over a five-year period. The resultant demands appear in column (2) of Table II. Bach and Barnett assume a value of $12.94 per tourist day for floating activity, based on Water Resources Council criteria. These values seem quite severely overstated. Based on our visits to the river, a score of 36 would seem to be a better indication of the value than their assigned score of 62. In particular: 1) Bach and Barnett assign a score of 10 out of 30 for recreation n/e/rra° -10- experience, which measures crowding. The large crowds projected here should reduce this value to 5. 2) Bach and Barnett assign a score of 12 out of 18 for availability of opportunity. A 12 would indicate no floating opportunities with one hour, which seems to ignore the French Broad and Hiawassee Rivers. We find 4 to be a more objective classification. 3) Bach and Barnett assign a score of 10 out of 14 for carrying capacity. This rating reflects "optimum facilities to conduct activity at site potential." These facilities are simply nonexistent. A 5, representing basic facilities, seems quite generous. 4) We accept Bach and Barnett's accessibility rating of 12 out of 18. 5) Their rating of an 18 out of 20 for outstanding esthetic quality seems highly inflated. The river would still receive municipal waste treatment discharges and both agricultural and urban runoff. We have lowered their rating to 10. The score of 36 translates to a value of $8.30 in 1982 dollars, converted to $9.76 in 1988 dollars. We have used this value in our estimate for floating activity. Table II describes the annual benefits and the present value of these benefits in 1988 dollars. The present value reflects the annual benefits over the next 10 years discounted to reflect the time value of money. We used a 10-year time frame since that is about the expected life of the investments for color discharge reduction. Discount rates reflect the rate at which benefits can be traded between years. We have discounted the benefits at an annual rate of 6.79 percent in excess of inflation. The rate used reflects the after tax cost of money to Champion (13.2 percent) net of a presumed six percent future inflation rate. The nm✓r/aa . -11- Champion rate reflects the marginal cost of capital in the private sector, since funds spent cleaning up the Pigeon River would otherwise. earn these private sector rates. The benefits of cleanup should consequently be discounted at the same rate. Using this method, we derive total benefits over the next 10 years of $8.9 million for rafting and $2.9 million for floating. The annual benefits and the present value of the benefits for whitewater activity and floating are given in columns (5) and (6) of Table II. We are quite confident that these estimates overstate the actual changes in value on the Pigeon River. There are at least six reasons why we expect the value of additional whitewater activity and floating visits to be substantially lower. Fib we have assumed that there is currently no recreational usage on the Pigeon River. In fact, there is a commercial operation on the river today. Kayaking and canoeing have also been observed on the river. However, we have been unable to secure estimates of current usage and have therefore ignored them. Since our goal is to calculate increases in usage, the value of all current usage should be' subtracted from our value estimates. Our failure to do so clearly overstates the number of trips that can be attributed to reductions in color discharge and thereby overstates benefits. Second the benefits per trip used for whitewater activity were estimated on much larger and more striking rivers in Colorado. The set of rivers on which this estimate was based includes, for example, the Yampa River, which "is among the few rivers in the U.S. on which rafters can spend from three to five days without encountering roads, private land, or other evidence of civilization." [6, page 8] The rivers sampled averaged 42 miles in whitewater length, over eight times the length of the Pigeon River run. Trips on these rivers averaged 14 miles per day. The shortest of the rivers was almost three times the length of the nje/Tids 12 Pigeon River. Such unique characteristics would be expected to make this set of rivers much more valuable than the Pigeon River. Third the $13 consumer value assumes a very modest increase in congestion. The value of a whitewater rafting day declines sharply with the number of people encountered on a trip. The Colorado study users encountered an average of only forty people on a trip. With visits of 120,000 per year, Pigeon River whitewater rafters might well encounter hundreds of people per day. In the Colorado study, a doubling of encounters reduces the benefits per day by over 40 percent. Thus, fairly moderate increases in usage could lower the benefit per day estimate substantially. Fourth of the two methods traditionally used to estimate the value of recreational activities, we relied on the contingent valuation method which usually leads to higher values. It is subject to a number of well-known biases in which people tend to overstate the value of services. Alternatively, travel cost models which estimate the demand for a service by the distribution of distances people were willing to go to participate in an activity, typically give lower values than contingent valuation. Fifth the current physical facilities at both the dropoff and takeout areas are grossly inadequate to the task of accommodating the estimated number of rafters or floaters. We assume that these facilities could be developed over time if demand warrants but have not included the costs of developing these facilities. These costs would properly be a subtraction from the benefits associated with these activities. Sixth, increased recreation visits on the Pigeon River may consist largely of visits currently made to other rivers. Thus, in equilibrium, the total increase in whitewater rafting trips might be much less than the 120,000 visits per year Tl�L/Zi`d,'a -13- projected on the Pigeon River even if that many people do raft on the Pigeon River. Each visit "cannibalized" from the Ocoee, Hiawassee, or any other river represents less new value than a new trip; most of its value reflects a shifting of value from one site to another. For these reasons we consider our estimates of both usage and value per trip to be quite generous and would expect to see far less rafting and floating usage of the Pigeon River. C. Fishing and Sightseeing For these activities we have used both the visit estimates and value estimates of Bach and Barnett as a base. They have scaled fishing visits to usage estimates for the Norris Dam tailwaters put-and-take fishery. Their sightseeing visits are scaled to estimates for the Hiawassee River. The number of visits for these activities are given in columns (3) and (4) of Table II. Our only adjustment is to lower fishing values to account for the costs of the presumed put-and-take fishery. Failure to include these costs overstates potential net benefits. One study [61 suggests that these costs can range from $4.50 to $11.00 per visitor day depending on the length of the fishery. We have used the average of this range to reduce Bach and Barnett's estimate of the net benefits for a fishing day of $17.00 to $9.25. Further, while we have used Bach and Barnett's estimates for the number of additional fishermen expected, the source of their estimate is unclear. A proper estimate should take into account the fact that trout are not a viable species in the Pigeon River below the Canton Mill discharge and that put-and-take fisheries are generally less efficient in smaller bodies of water. We have accepted their estimates for lack of better data. -14- It should be noted that fishing is a viable activity on the more scenic portions of the river only when whitewater rafting is unavailable. Excessive stream flow and heavy boating usage are detrimental to fishing quality. We do not regard this as a very serious constraint given the limited time available for whitewater rafting and have therefore made no adjustment. The annual benefits and the present values for fishing and sightseeing are described in columns (7) and (8) of Table II. The present value of fishing benefits is about $1.2 million over ten years, while sightseeing accounts for about $0.7 million. D. Proyerty Values It has been argued that reductions in color can enhance residential values. A 1979 study [2] in Pennsylvania, which focused on overall water quality rather than color, indicated that a completely clean river raises adjacent residential property values about 28 percent. Similar values were obtained for apparent color in a 1985 Michigan study [3] on lakefront property and for a combined index of turbidity and distance in a 1980 study [4] of beachfront property in Massachusetts. We have used the 28 percent figure as an upper bound on residential property improvements on the Pigeon River. We have further assumed that all property along the Pigeon River not currently blocked by roads, public land, or Champion property is transformed to residential use. This is obviously an extreme assumption and causes us to overestimate the impacts of reduced color discharge on property values. Our calculation of increased property values had three steps: 1) an inventory of property along the Pigeon River, 2) a calculation of its value for residential purposes, and 3) a calculation of the maximum increase in value attributable to reduced color. n/e✓r/W . -1s- 1. Much of the land adjacent to the Pigeon River is publicly owned. Route I-40 follows one side of the river while public forest land borders the river in many areas. The land between the dam and the powerhouse which contains no water due to the powerhouse diversion tunnel and is, therefore, unaffected by color was also excluded. Only about 50 percent of the river is adjacent to usable private land. We have also excluded plots belonging to Champion and the Cocke County School District. Since the usage of these properties cannot be expected to change with reductions of color in the Pigeon River, we have excluded this land from our assessment. 2. We had assessed property values for land in Tennessee only and have assumed that similar values prevail in North Carolina. Residential land and property was valued at $52.49 per river-foot of frontage. We have assumed that all land along the river would have this value in residential use. In fact, nonresidential land and property in Tennessee had a value of only $32.01 per river-foot. To calculate increases in the value per river-foot of frontage, we used the 28 percent figure. This increases the value of all potential residential property by $14.64 per river-foot to $67.13. The results of this calculation are given in Table III. Property value increases, which are assumed to be instantaneous, total $2.52 million in North Carolina and $2.05 million in Tennessee. Again, we feel it quite likely that this estimate overstates potential benefits. Fi= we have applied residential-level benefits to agricultural and commercial land. This is based on the assumption that this land may ultimately be converted to residential use. The available studies deal exclusively with residential values. The links between property value and color are far less obvious for land used for agricultural, forestry, or industrial purposes. However, it is unclear that I1�2/Y'id,� -16- private land along the Pigeon River currently used for agricultural or industrial purposes will be converted to residential use. Second the 28 percent increase cited is partly attributable to the fact that more expensive homes are constructed on more desirable land. The net benefit, which would subtract the cost differentials, is not included here. Third color may not be the true measure of property desirability but may instead be a proxy for other measures of environmental quality. A 1973 study [8] found color much less important to property owners than the ability to sustain fish and other wildlife. The Michigan study of lakeside property owners found that turbidity was an important factor in value but notes that turbidity is highly correlated with other pollution variables which decrease both fishing and swimming uses. To the extent that these variables are not correlated here, the effects might well be less. Fourth we have included several plots of land currently inaccessible by road. Several areas of vacant land doubtless have no developed residential infrastructure--for example, sewage, telephone and water access. The costs of providing such facilities should be subtracted from any property value increases. Given these caveats, we find it quite likely that the combined property value effects will be lower than what we have estimated. E. Atmortionina Benefits The recreational and property benefits we calculated in Sections II.B. through II.D. total $18.3 million over 10 years. These estimates are based on the complete elimination of color discharges from the Champion mill. The next step is to determine the proportions of these benefits that will accrue from each of the specific proposed reduction plans. 11�/IYc1i° -17- Under the most stringent reduction plan, discharges of color would be limited to no more than 50 units at the pipe. This strategy entails a reduction of 311,000 pounds of color per day on average. We have adopted the Bach and Barnett assumption that 50 units is the limit of color acceptability. Consequently, we have assumed that the 50 units at the pipe strategy achieves all of the $18.3 million in benefits. For the other two strategies, we have assumed that the benefits achieved are proportional to the reduction in discharges. Further, for the 50 units at the border scenario, we have assumed that the plant remains open. Thus, the strategy •that achieves 50 units at the border would achieve all the potential benefits in Tennessee. This includes all of the recreational benefits as well as the increase of $2.05 million in property values in Tennessee. In addition, since this plan also achieves 88 percent, of the discharge reductions under the 50 units at the pipe strategy (274,000 divided by 311,000), we assume it achieves 88 percent of the property value benefits in North Carolina. As a result, the total benefits from the 50 units at the border strategy are $18.0 million. The 50 percent reduction plan removes 172,000 pounds of discharge per day on average. This achieves 63 percent (172,000 divided by 274,000) of the Tennessee benefits and 55 percent (172,000 divided by 311,000) of the North Carolina benefits. Thus, the total benefits from this program are $11.3 million. This proportionality assumption is somewhat arbitrary. In the absence of specific recreational studies on color, it is unclear whether a 50 percent reduction in effluent will garner more or less than 50 percent of the benefits. Instead, there might be threshold, effects. That is, below a certain color level, all benefits accrue; above a certain level, no benefits accrue. While 50 units in the stream may represent the lower threshold, we have no such upper threshold. Further, even the I1�E',/ZSd� ' -1s- 50 unit lower threshold is controversial. However, we have tested several different upper thresholds in benefits. The assumption of proportionality yields larger incremental benefits than any other set of assumptions tested. F. Nonuse Value It is often asserted that there are values other than those accruing to users of the. river. Bach and Barnett cite a study which estimates those benefits at five times the direct benefits. We reject the notion that there are significant nonuse benefits for the Pigeon River. Fib it is unclear whether nonuse values for the Pigeon River are positive or negative. Second even if these benefits are positive, they are not likely to be large. The economics literature considers two components of nonuse values: option values and existence values. Option value is similar to a nonrefundable admission price that must be paid before one knows whether or not he or she will use the river. It represents for consumers the difference between (1) the willingness to pay to shield themselves from uncertainties about their demands for the river and its availability and (2) the expected value of their benefits from the river. Substantial theoretical research indicates that option value, this difference between willingness to pay and expected value of benefits, is as likely to be negative as positive. Further, in some important cases where it is positive, it is likely to be small. Whether option values are positive or negative depends on the nature of the uncertainties confronting users and nonusers. At least five sources of uncertainty can create option values. These include: (1) supply of the resource, (2) income, (3) taste, (4) price of the resource and (5) prices of substitutes or complements. Examples can be constructed where option value is positive, negative, or zero for reasonable uncertainty assumptions. Further, V. Kerry Smith's analysis n/e/r/W -19- [9] shows the importance of uniqueness and irreplaceability in assigning a positive option value. Given that the Pigeon River has no unique characteristics (especially given the abundance of substitutes) and that the level of color is reversible at any time, his analysis implies that option values are unlikely to be positive. Regarding the magnitude of the option value in the case of uncertainty about taste, Freeman [10] points out that the conditions for a large option value are quite stringent. Option value is unlikely to be large unless "the probability of demand is low, the expected consumer surplus is large, and the individual is highly risk averse." [10, p.11] For the Pigeon River, these specific conditions are unlikely to occur. In particular, rafting on the Pigeon River is quite unlikely to have a large expected consumer surplus relative to income given the abundant potential substitutes in the area, both for whitewater recreation and for entertainment in general. Finally, the empirical evidence on option value is generally unpersuasive. While several studies (including the one cited by Bach and Barnett) have concluded that option values were positive and substantial, these studies have been poorly done and cannot be used to infer large positive values. There are various reasons for this, including the fact that the survey questions addressed the wrong issues and were posed in a confusing manner. As Smith [11] points out: Empirical efforts to measure option price (and option value) have not been clear in specifying (or attempting to determine the individual's perceptions on) the terms of access to the resource and the time horizon for future use. . . .[T]he terms of access and the individual's ability to adjust to demand uncertainty . . . have not been clearly described (or elicited) from the respondents involved in the surveys. . . .[T]his limitation is especially important when the option price is used to measure the value of changes in either features of the resources or in the uncertainty itself. [11, p.8] As a result, these studies have generated estimates of surplus much too large to be easily explained on a theoretical basis. 11/e/t'/W _20_ Further, applying estimates taken from these other studies to the Pigeon River would be even more tenuous. Even if the wild and scenic rivers of Colorado may have significant option values, the transfer of those results to the Pigeon River is unwarranted. Considering all of these issues, we have-not included any option values in our estimates. Our best reason for doing so is stated by Professor Richard Schmalansee [12] of the Massachusetts Institute of Technology, one of the original contributors to the theory of option value: Individuals' option prices may exceed or fall short of the expected value of the contingent surpluses they would derive from a price change, and it is not obvious how one might judge in a real situation which was more likely. This suggests that when tastes are the main source of uncertainty, the expected value of consumer's surpluses ought to be employed as the best available approximation to the sum of their option prices . . . . Benefits will be sometimes underestimated and sometimes overestimated by this procedure, but there would appear to be no practical way to obtain superior estimates. 112, p.823] Existence values represent the utility of knowing of the existence of a resource for a person who knows he will never use it. We believe that this does not represent a significant source of benefits on the Pigeon River and have excluded them from our estimates for two reasons. Fib existence value is linked to uniqueness of the resource. A resource with features available nowhere else (for example, the Grand Canyon) may have substantial psychic value to nonusers. We do not believe that nonusers place a large value on the Pigeon River given the existence of nearby alternatives. Second a full specification of existence values would of course include foregone opportunities for the people of Canton. Those who would place a high utility on lower color levels in the Pigeon River should also place high disutility on the social disruption caused by the shutting of the Canton Mill. In scenarios in I1/evr/ad -21- which the mill must be closed, a positive existence value.would mean that people put less value on the disrupted lives of Canton than for color levels; in the Pigeon River. Thus, in this case existence value is the sum of two effects: one positive and one negative. It is not clear a priori which effect would predominate. Third little is known empirically about existence value. Testing for existence value is fraught with difficulty, since people not actually called upon to pay for improvements may systematically overstate, for any number of reasons, their willingness to pay. The most comprehensive study of existence (and option values) suggests that together they might increase benefit estimates by as much as 50 percent. Even these estimates have come under attack. We find that an increase of this size at the Pigeon River to be highly unlikely. However, we note in passing that even a tripling of all benefits in Table I still results in an unfavorable benefit-cost ratio for all reduction plans. The benefit cost ratios for the more stringent USEPA proposals require assumptions of option and existence values of ten to twenty times the direct effects. III. COSTS Colored effluent is the byproduct of the removal of lignin from wood chips in the pulping process. Currently, the mill is one of the lowest producers of pounds of color per unit of output in the United States. A. 50 Percent Reduction The primary source of color discharge is the caustic extraction stage of the bleach plant. Improvements proposed by Champion to cut this contribution by 90 percent would achieve an overall reduction of 50 percent. This reduction is proposed to be accomplished by the addition of oxidation chemicals. The costs of the 50 percent reduction proposal have been estimated by Champion at $10 million dollars in capital cost and $4 million per year in operating -22- and maintenance costs. We have converted these costs into a ten year stream and discounted them at Champion's after-tax cost of money. This yields a discounted present value of expenses over a 10-year period that is directly comparable with the benefit estimates. The operating and maintenance expenses were discounted using the 6.79 percent rate. The present value of the costs of this plan is therefore $38.4 million. The costs are summarized in Table V. B. 50 Units at the Tennessee Border Other technologies that would treat more than the caustic extraction stream require far greater investments. Champion submitted to the USEPA, at the Agency's request, seven reports detailing methods of reduction sufficient to achieve no more than 50 color units at the border at any time. Of these, the USEPA deemed as potentially suitable the lime, polyamine and alum removal systems. Each technology has a different capital and operating cost, with the alum removal system being by far the lowest cost. Further, the systems have different risks associated with them. Champion's engineers have supplemented the estimates of probable cost of each of these technologies with a probability distribution of costs. The proper cost to use ex ante in comparing the plans is the expected cost of the technologies, i.e. where the costs are weighted by the probabilities that they occur. Under this criterion, the polyamine technology has the lowest cost. The present value of its costs are $164.5 million, as opposed to $192.5 million for the alum reduction plan and $209 million for the lime reduction plan. Since the polyamine system is the least expensive of the three technologies that would achieve 50 color units of the border at any time, we have used it in the analysis. We should note that the polyamine removal process is likely to understate the cost, possibly greatly so. EjEaL no polyamine process on this scale has ever been implemented before. Large scale experiments with new technologies often have n/esrral -23- substantial unexpected cost increases. Second byproducts of the polyamine process would almost certainly violate existing environmental standards. In particular, operation of the sludge dryer would cause air quality deterioration in particulate matter, hydrocarbons, SOZ, and NO, The cost of meeting existing standards have not been included in these estimates. In calculating the results in Table I, we have assumed that the plant 'remains open at this level of expenditure. Champion has submitted to USEPA workpapers based on the USEPA gross margin test. This test compares the ratio of net operating revenues to annual pollution control costs. Where this ratio exceeds the average ratio of investment returns for the industry, "the test results indicate that pollution controls would impose severe economic impacts, [and] a more detailed plant closure analysis would be necessary." [14, page 92] Champion's submissions indicate that the 50 unit at the border strategy fails to pass this test. This raises the possibility of mill shutdown even under this plan. Were this the case, the quite substantial resource and employment costs of the more stringent December USEPA proposal would result. Only the 50 percent reduction plan would have costs within a factor of 50 times benefits. We have analyzed this case from a different perspective and find a persuasive case for shutdown. Our analysis suggests that the internal rate of return on an investment in pollution control (combined with the $200 million necessary to keep the plant commercially viable) is considerably less than the 20 percent hurdle rate necessary to justify an investment for Champion. Even were the investment of average risk for the company, the project would likely not be justified. In fact, the risks involved in both the pollution cleanup and oxygen delignification production process are substantial, requiring internal rates of return in excess of the hurdle rate to warrant the investment. We therefore regard the ri/evr/ i° _24_ 50 unit at the border proposal as likely to lead to shutdown of the Canton mill. Again, were this the case, the true costs and benefits of the 50 units at the border plan would be identical to those from the more stringent limit of 50 units at the pipe. C. 50 Units at the Mill Engineering judgment has determined that these color treatment schemes cannot simply be scaled up to achieve a discharge level of less than 34,000 pounds per day on the average, the amount sufficient to assure less than 50 units at Canton. Also, the mill would not be able to operate on pulp shipped in. Thus, the only method of achieving 50 units at the mill is the shutdown of the plant. In this case, the real resource cost of shutdown is the cost of constructing a new mill with replacement capacity elsewhere in the country. Champion estimates that the creation of a new mill capable of producing 600,000 tons of pulp per year would have capital costs of $1.4 billion. To properly characterize the total resource costs, we should subtract from this estimate the present value of savings in operating and maintenance provided by a new plant. Champion has proposed a $200 million investment in an oxygen delignification process which would allow the plant to continue operations. As a proxy for the operating and maintenance cost savings, we have assumed that the $1.4 billion investment creates a profit stream which yields an internal rate of return of 13.2 percent, i.e., represents an investment of average risk for Champion. This profit stream is then subtracted from the profit stream arising from the $200 million switch to oxygen delignification at the Canton mill. The present value of changed profits must represent the present value of cost savings associated with the new technology. The present value of resource losses thus totals about $290 million. The additional impacts of a shutdown are discussed below. Ili/r/w -25- IV. COSTS AND BENEFITS The economic criterion for undertaking any investment, including environmental enhancement programs, is that the benefits exceed the costs. Even where environmental benefits are themselves large, undertaking a project whose costs exceed its benefits is a waste of society's resources. Further, the difference between incremental costs and benefits should guide the choice between projects. While none of the three programs pass the benefit-cost test, the 50 percent reduction plan comes the closest by a wide margin. Under the 50 percent reduction plant the present value of the costs over a 10-year period are $38.4 million. These are $27.1 million greater than the benefits of $11.3 million. These costs and benefits translate into a benefit-cost ratio of 0.30 (11.3 divided by 38.4). The interpretation of this benefit-cost ratio is that a one dollar of expenditure yields 30 cents in benefits. The comparison of benefits and costs benefits are summarized in Table I. This is substantially less than one, and consequently would not pass the economic criterion for undertaking the investment. The plan to reduce discharges to 50 units at the border is even less justifiable. Its costs are $164.5 million, and they exceed the benefits of $18.0 million by $146.5 million. This results in a benefit-cost ratio of 0.11--nearly half of what could be achieved under the 50 percent reduction plan. The most costly program--50 units at the mill--achieves the poorest benefit-cost ratio. The costs would be much greater than either of the other plans because it would involve shutting down the Champion mill in Canton and constructing a new one. Under this program the costs would be $290 million. These are $271.7 million more than the benefits and would yield a benefit-cost ratio of .06. ri/2/r'rw -26- A very useful way to look at the alternative programs is by comparing the increase in costs and benefits that occurs from imposing increasingly stringent discharge removal plans. This is a comparison of the incremental costs and benefits and describes the additional benefits and costs that accrue from removing additional color. If the additional costs exceed the additional benefits, then the incremental reduction in color is uneconomic. As we have noted above, the least stringent of the programs--the 50 percent reduction plan--increases costs by $38.4 million and benefits by $11.3 million for a benefit-cost ratio of 0.30. The incremental cost of removing additional color under the 50 units at the border plan is $126.1 million--the difference between $164.5 million and $38.4 million. This added expenditure removes an additional 102,000 pounds of color per day (274,000 minus 172,000). However, this additional color reduction only increases benefits by $6.7 million (18.0 minus 11.3). Thus, the incremental benefit-cost ratio is 0.05 (6.7 divided by 126.1). The incremental comparison is even more unfavorable under the 50 units at the pipe plan as proposed by the USEPA. This program would increase costs by $125.5 million--from $164.5 million to $290.0 million. The added expenditures would achieve an additional reduction of color discharge of only 37,000 pounds per day. However, this additional reduction would only increase benefits by $300,000. As a result, the incremental benefit-cost ratio would be virtually zero. These incremental results depend crucially on the assumption of 50 color units as an objective perceptibility standard. If, in fact, there is no perceptible difference between 50 and 100 color units, then the conclusions are even more clear. Since the 50 percent reduction plan essentially achieves 100 color units or less at the border over 95 percent of the time, this plan would achieve all benefits, -Z7- no matter how large. Each of the more stringent plans, therefore, has incremental benefits of zero and cannot be justified on any rational criterion. In estimating the benefits and costs we have discounted the annual impacts at Champion's after-tax cost of money. Some have argued that the proper discount rate to use for the evaluation of projects should be a riskless discount rate. The basis for this argument is that since the benefits are spread over the population at large, the risk premium associated with private investment should not be included. We disagree with this argument. The reason is that funds spent on this project will deny Champion the ability to undertake other projects capable of earning the private rate of return. Hence the rate we have used is appropriate. We would agree, however, were this proposal financed with new money, but that would not be the case. Nonetheless, we have calculated the benefits and costs using a real discount rate of three percent, which is intended to represent a riskless rate. This substitution does not alter the results, and therefore our conclusions remain unchanged. Using a lower discount rate raises both the costs and benefits. For each case, the benefit-cost ratios are slightly less favorable. Table VI compares the results at the alternative discount rates. V. EMPLOYMENT CONSEQUENCES We have also estimated employment impacts from the three color discharge reduction strategies. Employment impacts are treated separately from the benefit-cost impacts because they represent different issues. Jobs created cannot be examined in isolation. For example, the cost side of the benefit-cost calculations reflects the employment impacts of the discharge reduction plans. Higher cost levels always create more jobs, whether or not the costs were incurred efficiently. Djevr/w -28- Thus, the employment consequences of a particular strategy cannot be added to benefits. Instead, they represent an alternative perspective. The 50 percent reduction strategy would likely have modest employment impacts of about 250 jobs. The 50 units at the border strategy, if implemented, would yield about 600 jobs. Given the probability that the plant would shut down, however, both this plan and the 50 units at the pipe strategy would impose very substantial employment losses totalling over 12,000 jobs. Jobs created and lost can be broken down into direct and indirect components: the direct component consists of the jobs required either to provide recreation or to maintain color reductions. Indirect employment gains and losses relate to the employment in other sectors required to support the direct work force. The U.S. Department of Commerce has issued state- and industry-specific estimates of total direct and indirect job impacts for given changes in output in various industries [13]. For recreation in Tennessee, we have used the hotels, lodging places and amusements multiplier. It indicates that for an increase of $1 million of expenditure in this industry group, direct and indirect employment will increase by 60.2 jobs. For discharge reduction activities, we have used the North Carolina values for the paper and allied products classification and the Tennessee value for forestry and fishing products. A $1 million expenditure in North Carolina provides 30.1 jobs, while a $1 million expenditure in Tennessee provides 54.5 jobs. The direct employment gains in Tennessee follow from the staffing requirements of the whitewater rafting facilities. Fishing, kayaking and sightseeing generate no direct employment gains, since they have no direct costs other than the costs of transportation. Using Ocoee River figures which show commercial rafting to account for about 85 percent of whitewater activity and using the Bach and Barnett figures of $20 per trip, we derive maximum expenditures in Tennessee for Tl/e/r/am _29_ whitewater rafting of $2 million (20x.85x120,000). This assumes the 120,000 visits per year associated with complete color removal. The multiplier of 60.2 direct and indirect jobs per $1 million in expenditures implies an increase of 123 jobs. The employment impacts are summarized in Table VII. Under either the 50 units at the border plan or the 50 units at the pipe plan, the concentration of color will be at the minimum levels of acceptability. Consequently, under either of these plans there will be the full employment impact of 123 jobs in Tennessee. The 50 percent reduction plan would have less of an employment impact because the benefits in Tennessee are less. Recall that we assumed that the benefits are proportional to the color reduction. Since with the 50 percent reduction plan the recreational benefits are 63 percent of those under complete color removal, the employment impacts also would be 63 percent of 123 or 77 jobs. The plan to provide 50 units at the pipe suggested by USEPA causes mill shutdown. This shutdown reduces Tennessee commercial output by $15 million as cited by the Canton Mill Operations Manager, Oliver Blackwell. This in turn causes a loss of 816 jobs, for a net loss of 693 jobs. For North Carolina the employment impacts depend on the annual capital and operating costs of a discharge reduction plan. The operating costs plus an annualized capital charge represent additional employment at the mill. Under the 50 units at the border plan, the annual capital and operating costs would be $17.91 million. This translates into 539 increased jobs (direct plus indirect) given the 30.1 multiplier. Under the 50 percent reduction plan the annual costs would be $5.85 million which would result in 176 more jobs. Shutdown of the plant under the USEPA standard would have substantial employment effects in North Carolina. The mill currently employs over 2,100 workers and produces $400 million of paper products per year. Using the 11/G/1/W -30- Department of Commerce multiplier of 30.1 jobs per million dollars of output for paper and allied products in North Carolina, a total loss of over 12,000 jobs can be projected. The direct losses to the community include the $160, million currently paid to local factors. Thus, in North Carolina and Tennessee combined, the USEPA standard would lead to a loss of over 12,000 jobs as well as widespread social costs from the withdrawal of Champion's substantial support both directly and indirectly through its employees and suppliers and through Champion's support of the Western North Carolina-Eastern Tennessee infrastructure through tax payments. VI. EVALUATION OF THE BACH AND BARNETT REPORT We have reviewed and evaluated the Bach and Barnett analysis and found it to be seriously flawed. There are four key conceptual errors that undermine their conclusions that it would be economic to substantially reduce color discharges from the mill. First they have failed to take into account the fact that benefits occurring in different years are not of equal value. Second they have included a category of benefits (indirect benefits) which have no place in a properly designed benefit-cost study and which have been misestimated in any case. Third, their examination of costs was entirely hypothetical and bears no relationship to the benefits achieved. Fourth they have employed the wrong standard in evaluating the possibility of mill shutdown. The appropriate way to evaluate discharge reduction strategies is on the basis of their impacts on the Canton mill. Bach and Barnett evaluate the strategy on a Champion-wide basis. We will address each of these issues in the following sections. A. Discounting The primary distinction in direct benefits between our analysis and that of Bach and Barnett involves discounting. Bach and Barnett simply sum the year- nj ✓I'/w -31- by-year benefits to yield a total. This is obviously incorrect. A dollar of benefits today is worth more than a dollar of benefits tomorrow, just as a dollar of income today is worth more than a dollar of income tomorrow. Discount factors which reflect the relative utility of current and future consumption must be applied to accurately measure the value of future benefits. Indeed, once appropriate discount rates are applied, the Bach and Barnett estimates of recreational benefits are slightly lower than ours. Application of our 6.79 percent discount rate lowers the Bach and Barnett direct benefit estimates from $18.3 million to $13.1 million. Our corresponding estimate of direct recreational benefits is $13.72 million (see Table II). B. Indirect Benefits Bach and Barnett add to the recreational benefits indirect benefits reflecting increased expenditures in the community resulting from the recreational activity. We have strong objections to this technique. Most importantly, this type of benefit has no place in a properly done benefit-cost study. Secondly, even were these benefits to be included, they have overstated both the level of expenditures to which these indirect multipliers should apply and have overstated the multiplier to be used. The proper standard for a benefit-cost study is the real resource costs and the real benefits. In comparing the real resource costs and benefits of the specific proposals mentioned here, we have a criterion which is independent of the indirect benefits. All programs have indirect benefits. Removing those indirect benefits can therefore have no effect 'on the analysis. Since the money spent on this project will be spent in some other way, the indirect benefits are essentially independent of the program undertaken. -32- Indirect economic multipliers represent a flawed concept taken in aggregate. The problem is that money spent on whitewater rafting does not reflect new income but is instead the shifting of income from another purpose. A dollar spent on whitewater rafting is a dollar not spent on other outdoor activities or other recreation. The economic multiplier of the dollar spent on whitewater rafting is offset by the loss of the same multiplier from the foregone activities. In aggregate therefore, these indirect benefits should be ignored. Each dollar of indirect benefit represents an indirect dollar of loss to someone else. If one is interested in the net economic benefits for a smaller region, this can be calculated. However, we must be careful to subtract out expenditures which cancel out within the region. To the extent that persons from outside Cocke County are induced to spend money in Cocke County, those dollars will create indirect benefits in Cocke County. Only expenditures by those outside Cocke County create these spillover effects within Cocke County. However, the number of such visitors is likely to be small. Unpublished data on a nearby river indicate that 41 percent of all river users travelled less than one hour to the river. Using these data, we have defined the region of direct economic interest is that within one hour of the Pigeon river. Thus, multipliers would apply to only 59 percent of all expenditures. Using the average expenditure figure cited by Bach and Barnett of $20 per day, we find that a total of $8.1 million (in present value terms) should have a multiplier attached. This value likely overstates the benefits. For those travelling in excess of three hours, it is highly unlikely that they would take a trip as short as those on the Pigeon River. The abundance of alternative fishing, floating and sightseeing areas and the comparatively low value of these activities make it unlikely that any IL�P-✓Ifd,® -33- long distance visitors would use the Pigeon River for these purposes. Either the Chattooga or French Broad on which longer trips are available should be preferred by visitors travelling long distances, especially given the uncertainty of water supply on the Pigeon River. Bach and Barnett use a multiplier of three to calculate the indirect benefits. This estimate reflects the spillover effects for the whole country, not just the region. The correct value is much smaller. For example, assume an individual spends $500 on a raft. If the raft was not manufactured in Tennessee, the spillover benefits will be created wherever payment for the raft goes. By the theory outlined above, inclusion of these benefits as a spillover is illegitimate, since these spillovers are exactly offset elsewhere. The U.S. Department of Commerce estimates state-by-state multipliers for hotels, lodging and amusements. For Tennessee they have calculated the direct and indirect benefits to the region as 2.1 times the dollars spent. Indirect benefits therefore are 1.1 times direct dollars expended. This is the 2.1 less the 1.0 for the direct effect. Thus, instead of using an estimate of indirect benefits equal to three times the direct benefits, a more realistic appraisal would be indirect benefits equal to at most 65 percent of the direct costs, which is 1.1 times 59 percent of the costs. Total indirect benefits would therefore total about $8.9 million. Further, these indirect benefits have offsetting indirect costs in the mill shutdown case. Given the net output losses of $400 million based on expected 1988 mill sales and using the Department of Commerce multiplier of 2.2, we project indirect losses of $480 million for the most stringent plan, resulting in combined indirect losses of over $470 million for both states. Given the importance of the mill to the local economy as the largest employer, it is possible that these values substantially understate losses associated I1�L✓ZYd,� -34- with termination of pulping facilities. For instance, the mill pays almost $1.7 million in taxes per year to counties and municipalities over and above taxes paid by its employees. The impacts of these local tax losses on social services and education are not calculated here. C. The Costs of Color Reduction Bach and Barnett assume a capital cost of $60 million and an operating and maintenance cost of $6 million. The present value of this expenditure, $102.5 million, is insufficient even to achieve 50 units at the border. Further, we note that even by their own analysis, the costs of cleanup far exceed the benefits. D. Financial Impact on Champion International Corporation In evaluating the impact of these expenditures on Champion rather than on the financial viability of the mill, Bach and Barnett have used the wrong standard. No matter how small the impact on Champion's overall balance sheet, the economics of the Canton mill must stand on its own merits. An incremental investment which fails to achieve a suitable rate of return is not justified. Champion has submitted to USEPA documentation supporting the fact that the 50 units at the border plan fails to pass the plant gross margin test. Under this standard, plant economics do not support even this less stringent plan. Further, our analysis indicates that the returns to this investment are insufficient to warrant continued operation of the plant.

The loss of $15 million of output in the last case is taken from Oliver Blackwell's testimony before USEPA, page 27. 2 Changes in output for North Carolina are calculated as follows: for the first two plans they are derived by adding the operating and maintenance cost of a plant and the capital cost multiplied by the capital recovery factor (.186) . For the 50 units at the mill plan, the loss in output is equivalent to the current output of the mill. 3 Multipliers are derived from RIMS manual, reference [131 .
