Hastings, Chicago, Ill., Alan S. Ward, Allan J. Topol, Washington, D.C., for plaintiffs-appellees. Before SWYGERT, Chief Judge, and FAIRCHILD and CUMMINGS, Circuit Judges. SWYGERT, Chief Judge. — 1 — This appeal presents the question of whether an ordinance of the City of Chicago that bans the use of detergents containing phosphates is unconstitutional on the ground that it results in an impermissible interference with interstate commerce. The district court decided that the ordinance is unconstitutional.1 We disagree. — 2 — The ordinance was adopted by the City Council after its Committee on Environmental Control had held public meetings for three days. The measure provided that the sale of detergents containing any phosphorous after June 30, 1972 constituted a criminal offense.2 Most detergents sold in this country contain phosphates which are compounds containing the element phosphorous. — 3 — The present action was brought seeking declaratory and injunctive relief. Plaintiff-appellee Procter and Gamble Company is a manufacturer of phosphate detergents. Plaintiff-appellee FMC Corporation processes and manufacturers sodium tripolyphosphate and other phosphate products for use in detergents. Three other plaintiffs were dismissed for failure to prove the jurisdictional amount and have not appealed. The second amended complaint alleged only a violation of the Commerce Clause of the Constitution (Article I, Section 8, Clause 3) and the case was tried on that issue. — 4 — A substantial amount of evidence, including exhaustive expert scientific and technical testimony by many witnesses, was presented both in court and by depositions. As the district court observed, this evidence is much too extensive to be set out in any detail. We think we need present only a broad outline of the more relevant evidence. — 5 — The plaintiffs unquestionably showed that the ordinance has had an adverse effect upon their businesses which admittedly are national in scope. Procter and Gamble was unable to sell any detergents in the Chicago area for five months after June 30, 1972 and lost $4,700,000 in sales as a result. FMC lost $500,000 worth of sales of phosphates as a result of the ordinance. Further, whereas before the ordinance Procter's Chicago plant was able to supply over 96 percent of the requirements for the six-state 'Chicago Plant Area,' after the ordinance became effective the plant could supply only 51 percent, which necessitated shipments to this area from other Procter plants in Louisiana, Missouri, and Kansas. The result was the establishment of a different and, from the company's viewpoint, a less efficient interstate system of distribution of its products. — 6 — Evidence was also introduced concerning the warehousing practices of the retail grocery chains serving Chicago and the surrounding area. These chains, which include chains of independents, warehouse their products on an areawide basis as opposed to a city-wide basis. Goods are purchased from the manufacturer and stored in warehouses for eventual distribution to the individual retail stores. In the Chicago area, the same warehouses also service stores in northern Illinois, northern Indiana, southern Wisconsin, and Michigan. At the warehouses, each product is stored in its own particular area called a slot. There was testimony that these warehouses will not 'double slot' a product and thus refused to carry both phosphate and non-phosphate versions of the same product. The explanation is that there is not sufficient space in the warehouses and there would be the possibility of a violation of the ordinance if phosphate formulas were accidently shipped to Chicago stores. Of the seventeen major Chicago area customers of Procter and Gamble, fifteen chose to carry only non-phosphate detergents. The result has been that consumers in areas of Illinois or the other adjacent states where the sale of phosphate detergents is legal can purchase only non-phosphate formulas of the major detergents from stores which are part of these fifteen chains. Thus, the Chicago ordinance affected Procter and Gamble's ability to sell its phosphate detergents in other states. — 7 — The bulk of the evidence dealt with the nature and effect of phosphates and particularly their effect on the water moving in the Illinois Waterway. Phosphates are not a problem in and of themselves. They are not harmful to most humans and are even added to water by some communities for the purpose of softening. The aspect of phosphates that causes concern is their nutritive contribution to the eutrophication of rivers or lakes. Eutrophication is a process of aging, whereby a body of water becomes over-nourished in nutrient elements such that there occurs an extensive growth of green plants or nuisance algae. Nuisance algae can result in an unpleasant odor and a bad taste in drinking water. It is the elimination and prevention of these algae that is desirable. — 8 — Some controversy exists, however, concerning the relationship of phosphorous eutrophication. An abundance of phosphorous does not always result in increased eutrophication. It is a more complex process and its exact nature is somewhat in dispute. Other nutrients including nitrogen and carbon are needed for eutrophication. So far as the nutrient aspect of eutrophication is concerned the important inquiry centers on the idea of the 'limiting nutrient' or 'limiting factor.' The 'limiting nutrient' is that nutrient that is in the shortest supply relative to the need for it for plant growth. It is the factor which limits any further aquatic growth. The district court found that phosphorous can be a 'limiting factor' for nuisance algae only at .02 milligrams per liter or less. There is some evidence, however, that phosphorous is the nutrient that is most easily controlled. — 9 — The ordinance's most direct effect is on the Illinois Waterway because the City's sewage effluent flows into it. This Waterway, which includes the Illinois River, is a water source for some communities, but not for Chicago. The Waterway has a very high percentage of phosphorous. The district court determined that before the passage of the ordinance the amount of phosphorous present in this Waterway was at least twenty-five times as much as is necessary to sustain nuisance algae. Still, there is a question of whether there is any nuisance algae problem in the Illinois River. Although the City introduced photographs showing the presence of such algae, the district court concluded 'that there was no significant amount of nuisance algae in the Illinois River.'3 Explanations offered for this lack of growth included the excessive turbidity of the river which prevents needed sunlight, periodic flushing, and possibly some undefined trace elements which inhibit such growth. Also, the district court found that the elimination of Chicago phosphates alone would not result in reaching the 'limiting factor' level, though a 66 percent reduction did result in at least part of the Waterway after the ordinance had been in effect. — 10 — Finally, there is the evidence concerning Lake Michigan which is the source of Chicago's water supply. The danger of nuisance algae is more pronounced with regard to Lake Michigan because it does not have the flushing quality of a river. Moreover, the phosphorous concentration is at about the 'limiting factor' of .02 milligrams per liter. But unlike some of the other communities along the lake, Chicago's sewage does not normally flow into the lake; only during excessively heavy rainstorms is one of two rivers reversed so that sewage flows into Lake Michigan. The district court determined that such reversals occurred only four times within a ten year period, though there was also testimony that the frequency of such reversals is increasing. As to the amount of phosphates entering the lake during a year in which a backflow resulted, the conclusion of the district court was that detergents contributed only 250 tons or about three percent of the total entering the lake each year. — 11 — Based on this evidence the trial court determined that the phosphate ban was unconstitutional. It decided that the ordinance resulted in increased costs of manufacture and distribution and burdened interstate commerce. Once the plaintiffs had proven this much the court held that the City was then required to justify the ordinance by showing some need to protect the public health, safety, or welfare. Though it found that the 'ordinance was enacted in good faith and for laudatory objectives,'4 the justifications offered for the ordinance were not sufficient to outweigh its interference with interstate commerce. The court held that the City did have the power to protect the water quality for persons living downstream, but the ordinance by itself would not have any beneficial effect on the Illinois Waterway. The actual effect on Lake Michigan was apparently considered too minimal to support the legislation; the theory that the City could enact the ordinance in order to influence other communities to stop discharging phosphates into Lake Michigan was rejected. Though the court conceded that such an ordinance might be sustained in some other jurisdiction where the water supply situation is different, it concluded that Chicago could only enact the ordinance on a standby basis to become effective only when other controls have brought the phosphorous content of the Illinois Waterway down to the 'limiting level.' — 12 — * It is difficult to discern the precise test that should be used to determine when a state or local legislative enactment's effect on an area of interstate commerce that has not been pre-empted by Congressional legislation is violative of the Commerce Clause of the Constitution. It is clear that we must first decide whether there is such an effect and what it is, for if we find no effect our inquiry need not progress. However, if some effect is found then we must proceed to consider whether the legislative body 'has acted within its province, and whether the means of regulation chosen are reasonably adapted to the end sought.'5 The more difficult question is whether our analysis should encompass an additional step if the legislation is found to be a reasonable means of achieving a legitimate end. The predominant test utilized by the Supreme Court appears to require that the burden imposed on interstate commerce be balanced against the local benefit in order to determine the ultimate question of constitutionality. See Bibb v. Navajo Freight Lines, Inc., 359 U.S. 520, 79 S.Ct. 962, 3 L.Ed.2d 1003 (1959), and Southern Pacific Co. v. Arizona, 325 U.S. 761, 65 S.Ct. 1515, 89 L.Ed. 1915 (1945). The Court's most recent formulation is that contained in Pike v. Bruce Church, Inc., 397 U.S. 137, 142, 90 S.Ct. 844, 847, 25 L.Ed.2d 174 (1970): — 13 — Where the statute regulates evenhandedly to effectuate a legitimate local public interest, and its effects on interstate commerce are only incidental, it will be upheld unless the burden imposed on such commerce is clearly excessive in relation to the putative local benefits. — 14 — There is some support, though, for the proposition that once it is determined that the legislation is a reasonable means of achieving a nondiscriminatory, legitimate goal it should be deemed constitutional and any further weighing process need not occur.6 One commentator has suggested that this 'third stage' balancing process is undesirable because it can lead to the usurpation of the legislative role.7 Moreover, it is argued that in fact the Supreme Court has perhaps eliminated this final balancing step by its opinion in Brotherhood of Locomotive Firemen & Enginemen v. Chicago, Rock Island & Pacific Railroad Co., 393 U.S. 129, 89 S.Ct. 323, 21 L.Ed.2d 289 (1968). Brotherhood involved the validity of the Arkansas 'full-crew' laws for railroads. The district court had analyzed conflicting evidence concerning the safety value of such laws and determined that at best they provided for a small increment in safety not worth the cost. This was found not to outweigh the burden on interstate commerce. In reversing, the Supreme Court indicated that the analysis endorsed by the lower court was incorrect: — 15 — We think it plain that in striking down the full-crew laws on this basis, the District Court indulged in a legislative judgment wholly beyond its limited authority to review state legislation under the Commerce Clause.8 — 16 — The matter was one properly left for the legislature because the evidence 'leaves little room for doubt that the question of safety in the circumstances of this case is essentially a matter of public policy, and public policy can, under our constitutional system, be fixed only by the people acting through their elected representatives.'9 — 17 — The Brotherhood case has been relied upon in cases similar to the one at bar. In discussing the Commerce Clause implications of an environmental statute a state court commented: — 18 — The language of Pike v. Bruce Church, Inc., supra, does not mechanically compel a weighing process in every case. The language is instructive in appropriate cases rather than mandatory in all cases. . . . The United States Supreme Court recognized the inappropriateness of a weighing process in cases of non-comparable benefit and injury . . . in Firemen v. Chicago, R.I. & P.R. Co. . . ..10 — 19 — Indeed, one court confronted with a challenge to the same type of legislation before us adopted the Brotherhood opinion as the controlling case.11 — 20 — Our case, we believe, has elements that require a compromise between Brotherhood and Pike. Like Brotherhood there is conflicting evidence concerning the value of this legislation. Here the conflict relates more to the question of whether the ordinance will result in preventing nuisance algae, as opposed to the question of how much benefit there is from the removal or prevention of such algae. The latter is the type of 'public policy' question that is directly addressed in Brotherhood. The district court did not and should not have evaluated the benefits to be derived from the improved water quality associated with the elimination of nuisance algae. It was proper, however, for the court to consider the 'factual' question of whether the ordinance has any relationship to the elimination of nuisance algae. The question that we are faced with is how much weight, if any, should be accorded the legislative body's determination that the means are reasonably related to achieving the end. In the present case we think that it is at this point that the Pike balancing stage occurs. The district court addressed this issue as if it was an ordinary factual dispute over a technical matter that should be decided without the benefit of a presumption. It is our view, however, that if the burden on interstate commerce is slight, and the area of legislation is one that is properly of local concern, the means chosen to accomplish this end should be deemed reasonably effective unless the party attacking the legislation demonstrates the contrary by clear and convincing proof.12 If it is determined that this presumption should be applied, no further balancing need be undertaken. The end has already been deemed legitimate and the burden on interstate commerce slight. If the legislation is a reasonable means to that end it is constitutional. II — 21 — Having in mind the framework of our analysis, we begin by considering what, if any, burden was imposed on interstate commerce by this ordinance. The first major argument raised by the plaintiffs, and apparently accepted by the district court, is that the ordinance burdened interstate commerce by impairing the normal operation of companies having interstate sales and requiring these companies to create new, and less direct, shipping routes. This argument is based on the fact that Procter and Gamble's plant in the Chicago area could not adequately supply its six-state area with detergents because the plant had to manufacture two lines of detergent products and thus reduce its capacity. The result was that products had to be shipped to some of these states from plants which happened to be at different, and often further, locations. The principal cases relied on to support this theory involve interstate carriers whose ability to efficiently transport other's goods through particular states was permanently impaired.13 With our case, we are not confronted with a situation in which legislation has reduced the effectiveness of a means of transportation itself. In this context the ordinance is not a burden on interstate commerce, but is merely a 'burden' on a company which happens to have interstate distribution facilities. The effect of the ordinance is that the particular interstate systems of distribution used by Procter and Gamble and other detergent companies before the passage of the ordinance can no longer be used. This is because of the freely chosen geographical locations of their various plants, not because of the requirements of this ordinance. There is no impairment of the ultimate ability to transport in interstate commerce in the most efficient and economical manner possible. While this factor might necessitate a change in certain production facilities, it does not rise to the level of an unconstitutional burden on interstate commerce.14 — 22 — Plaintiffs also argue that the ordinance is a burden on interstate commerce because there is a 'potential for conflicting legislation.' Other jurisdictions, including some within the Chicago marketing area, have enacted phosphate detergent legislation, and it is urged that such local legislation might conflict with each other so as to inhibit the uniformity necessary for the national manufacture and distribution of detergents. It is claimed that Milwaukee has an ordinance that not only restricts phosphates, but also prohibits highly alkaline detergents which have been used as substitutes for phosphate detergents. But there is no evidence in the record to prove that any phosphate substitutes used by the appellees in Chicago violate Milwaukee's ordinance. The Supreme Court has indicated that in a case involving environmental legislation it is actual conflict, not potential conflict, that is relevant.15 Moreover, once again the plaintiffs have drawn the main support for their argument from the cases involving interstate carriers. The importance of uniformity is not as great in the present type of case in terms of interstate commerce. As Judge Stevens of this circuit has stated: — 23 — (W)e think it certainly is true where you have a carrier who necessarily goes from state to state carrying the goods of third parties there is a higher interest in uniformity throughout the nation, but with respect to a commercial enterprise such as a manufacturer of detergents there is not the same national interest in uniformity throughout the country.16 — 24 — No burden has been shown based on this theory. — 25 — Another argument presented by plaintiffs is that the ordinance burdens interstate commerce because it amounts to an embargo on a safe, useful, and unique product of commerce without any corresponding local benefit. We find no merit to this argument. In essence, it is not a Commerce Clause argument but one based on substantive due process, an issue not before us. The only Commerce Clause cases cited for this proposition involve situations in which a state has attempted to achieve a local purpose by discriminating against out-of-state producers or manufacturers.17 There is no discrimination in this case. The ordinance does not require that detergents be manufactured in Chicago or Illinois and does not benefit manufacturers who are located there. — 26 — There is one theory of plaintiffs, however, in which we find some merit. This ordinance does have an extraterritorial effect because of the four-state warehouse marketing system employed by the major wholesale purchasers of detergents. Since a substantial number of the retail grocery stores within a 150 mile radius of Chicago are supplied from seventeen grocery warehouses in or near Chicago, the refusal of these warehouses to 'double slot' detergents means that many people outside Chicago cannot buy phosphate detergents even though they wish to use them. Potential purchasers in other states are prevented from obtaining a detergent formula that manufacturers may legally sell in those states. Though the ordinance may not directly dictate such a result, one effect is that the free flow in commerce of a particular product is disrupted. Such a disruption must be deemed a burden on interstate commerce. — 27 — Still, there is the question of how substantial is this burden. It is important to realize that this burden is one that was not intended by the City Council, even though that factor is not determinative. The effect is an incidental one due to the nature of the grocery warehouse system over which the City Council has no control. — 28 — Moreover, all the potential purchasers of phosphate detergents in this area outside Chicago are not affected by the ordinance. Other jurisdictions in the Chicago marketing zone also have limitations on phosphate detergents. Purchasers in these areas are restricted by their own local legislation. And in the areas without such legislation phosphate detergents assumedly will be available at those stores which are not part of these chains. Two of the seventeen chains chose to carry phosphate formula detergents, so such products will also be available at those stores. While there might be people who cannot buy phosphate detergents in their own towns, the foregoing factors tend to lessen the burden. Indeed, there is the possibility that manufacturers might be able to 'drop-ship' directly from the plant to stores in some areas. Although this might not be the customary or most economical procedure, Procter and Gamble distributes its products in this manner for about one percent of its total business. — 29 — We are troubled by the contention that these large warehouses absolutely refuse to stock two formulas of the same detergent. Procter and Gamble and the other two large detergent manufacturers are huge companies that could exert at least some 'leverage' on these warehouses. Admittedly, there is testimony that Procter and Gamble has tried to convince them to handle both and has had very limited success. But we wonder whether such leverage would not increase when this lawsuit is not a consideration. One would think that the grocery chains would have an incentive to carry both types of detergents in order to compete with those stores selling what Procter and Gamble claims is the 'superior' detergent formula. — 30 — We are not totally persuaded by the grocery chains' explanation of why only one type of detergent can be stocked. The major reason presented is lack of space. But it would seem that the total number of boxes of detergents sold would be about the same whether two formulations or only one are offered. The aggregate supply of cartons kept in the warehouse would not increase unless it is necessary to maintain the same amount of product in stock even though less of it is being sold. It is not clear from the record why more actual space in the warehouse would be necessary if the same number of cartons is separated into two types rather than one. Possibly, the explanation is due to the limited availability of warehouse slots which, in at least some warehouses, are metal racks. But again the record does not show why the slots that are used for detergents cannot be split into two smaller slots that could accommodate the stock necessary for each type of detergent, assuming the total number of boxes in stock has not changed. — 31 — Nor can we unquestionably accept the contention that carrying both types of detergents would result in a great risk of accidental shipments to and sale of phosphate detergents by stores within Chicago in violation of the ordinance. If this were the only concern we are sure that some procedure could be arranged to minimize this possibility. For instance, the cartons that contain boxes of phosphate could be made a different color so they would be easily distinguishable. Certainly under such a procedure the employees of the individual stores could recognize a mistake and not sell the illegal detergent. — 32 — We recognize that the Chicago ordinance combined with the grocery warehousing practice can result in interfering with the full distribution of phosphate detergents to areas outside of Chicago. But many of these consumers would probably have access to such products either at other stores or at chain stores that might receive drop-shipments. Our analysis has indicated that if there was sufficient demand it might even be possible that all the large warehouses would carry phosphate detergents. Overall, we conclude that the ordinance's effect on full access to certain products by consumers in parts of other states can only be classified as a slight burden on interstate commerce. III — 33 — Having determined that the ordinance does impose some burden on interstate commerce, we are required to consider whether the interest sought to be served by the legislation is a legitimate local concern. As with most cases of this type, the goal of this legislation can be stated in its ultimate terms--protection of health and welfare. For purposes of our analysis, we believe that it would be more useful to express the objective simply as the prevention and elimination of nuisance algae. This is an environmental objective toward which local legislation may properly be aimed. In broad terms, this legislation is part of the overall attack on the problem of water pollution. Though there is federal intervention in this general area, this does not prevent local attempts to deal with one of our most immediate and difficult problems.18 As the Supreme Court has said in regard to a city's power to enact legislation designed to curb pollution: — 34 — In the exercise of that power, the states and their instrumentalities may act, in many areas of interstate commerce and maritime activities, concurrently with the federal government.19 — 35 — Indeed, Congress appears to have specifically encouraged such local legislation.20 The Federal Water Pollution Control Amendments of 1972 provide:Except as expressly provided in this chapter, nothing in this chapter shall (1) preclude or deny the right of any State or political subdivision thereof or interstate agency to adopt or enforce (A) any standard or limitation respecting discharges of pollutants, or (B) any requirements respecting control or abatement of pollution;21 — 36 — Moreover, as noted earlier, there are no discriminatory aspects associated with this purpose that might invalidate it. The objective is legitimately local and non-discriminatory which means that it may properly be the end toward which local legislation is addressed. — 37 — Finally, we see no problem in the fact that the ordinance is aimed, at least in part, toward nuisance algae downstream from Chicago. We agree with the conclusion of the district court that the City can be legitimately concerned with preventing any damage to its neighbors caused by Chicago's actions. IV — 38 — We are now at the stage where we must determine whether the ordinance is a reasonable means of reaching the end desired. We have previously concluded that the burden on interstate commerce that results from this ordinance is slight and the objective of this legislation is legitimate. We hold that the burden is so slight compared to the important and properly local objective that the presumption we discussed earlier should apply. We will accept the City Council's determination that this phosphate ban is a reasonable means of achieving the elimination and prevention of nuisance algae unless we find that the plaintiffs have presented clear and convincing proof to the contrary.22 — 39 — We discuss first the Illinois Waterway because this is the heart of the factual controversy. An initial consideration is whether there is presently a nuisance algae problem in the Illinois River. The City did introduce some testimony and photographs indicating the existence of excessive algae blooms in the Illinois River. But the plaintiffs presented credible evidence to the effect that presently there is no nuisance algae growth in the Waterway. The district court concluded that there was no 'significant' growth. We can at least assume that there is some nuisance algae and the possibility of more in the future, since there was no convincing proof that such an increase will not occur. The testimony that the excessive turbidity and flushing quality of the river prevent algae blooms is far from conclusive. Indeed there are apparently some nuisance algae at present. The inhibitory factor might be a nutrient other than phosphorous that will greatly increase in concentration. The prospect for the future is unknown. — 40 — The crux of the matter is actually the question of whether the phosphorous level in the Waterway will ever be relevant to the control or removal of nuisance algae. We do not believe that the plaintiffs have met their burden of showing convincingly that limiting the quantity of phosphorous can never be the key to the problem. Admittedly, the evidence seems clear that phosphorous is not the 'limiting factor' in the Waterway at this time. Moreover, even with the elimination of detergent phosphates from the Chicago sewage effluent, the phosphorous level would not reach the limiting point. The Chicago ordinance, by itself, would have no immediate effect on the Waterway. This does not indicate, however, that the ordinance is not a means of dealing with nuisance algae. The plaintiffs introduced evidence to show that the amount of phosphorous in the Illinois River could greatly increase without increasing nuisance algae. Even if this is true, it only proves that phosphorous is presently not the 'limiting nutrient.' It does not prove that phosphorous might not be the 'limiting nutrient' at some point in time. Indeed, Chicago's ordinance appears to be a significant first step toward that goal. We do not agree with the district court that it can only be enacted on a stand-by basis. If this were the law, all programs aimed at eliminating phosphorous from the Waterway would have to be enacted at the same time. We can assume that other communities might follow Chicago's lead and prevent phosphate detergents. Nor do we think that there was clear evidence that if all phosphorous from detergents were eliminated there would still be other uncontrollable sources that would keep the level above the limiting point. There was testimony that indicated that agricultural run-off of phosphorous can be controlled. For Commerce Clause purposes the City Council was justified in believing that eventually its phosphate ban, in conjunction with other actions, would result in eliminating and preventing nuisance algae in the Illinois Waterway. — 41 — The effectiveness of the legislation is also shown, to some extent, by the evidence concerning Lake Michigan.23 There is no question that both eutrophication and phosphorous are serious problems in regard to Lake Michigan. Though Chicago might contribute relatively little phosphorous to the lake, the phosphorous level is at such a precarious point that even this minimal amount takes on added importance. Further, contrary to the district court's view, we find that Chicago has a legitimate interest in banning phosphate detergents as an example for other communities presently releasing their sewage into Lake Michigan. Chicago is attempting to convince these communities to control their phosphate discharge into the lake. Chicago could reasonably decide that it would be aided in this endeavor if it could show these other jurisdictions that Chicago is willing to endure whatever hardships may be associated with the loss of phosphate detergents. Given the other aspects of the legislation that support its presumption of effectiveness, we need not reach the question of whether this hortatory element by itself could support the conclusion that the ordinance provides a means sufficiently effective to be declared constitutional. Based on all the evidence the presumption afforded the City Council's judgment has not been overcome. — 42 — This case has presented a very difficult constitutional problem. On the basis of the above analysis we have resolved the question in favor of the constitutionality of the ordinance. Accordingly, the judgment of the district court is reversed.

Elimination of phosphates by means too great a waste of chemicals to be deemed a constitutionally mandated alternative. See generally Dean Milk Co. v. City of Madison, 340 U.S. 349, 71 S.Ct. 295, 95 L.Ed. 329 (1951) [23] The City has argued in its brief that the ordinance also helps Lake Michigan because it has the result of preventing other areas from receiving phosphate detergents too, and thus these areas are forced to control their discharge of phosphorous into the Lake. We totally reject the contention that the effectiveness of the ordinance can be supported on the basis of this extraterritorial coercion. We do not believe that the City Council considered this possibility and we in no way rest our decision on this argument
