proceedings to evaluate separate costs. The record does not indicate how the failure of the Commission to consider the Utility’s overall financial condition, such as it would in a complete rate case pursuant to KRS 278.190, renders the surcharge rates to be inherently unreasonable. If the protestants believe the overall rates are not fair, just and reasonable, they may seek remedy pursuant to KRS 278.260. However, to add the requirement that the Utility demonstrate that it is not earning in excess of a previously approved rate base would mandate a full review of the Utility’s earnings, or a general rate case pursuant to KRS 278.190. The judicial imposition of such a requirement would frustrate the législative action in authorizing a utility surcharge provision. In addition, if the Commission, on its own motion and after a hearing, finds that the overall rates are not just and reasonable, it can authorize just and reasonable rates to be followed pursuant to KRS 278.270. By comparison, separate rate proceedings for fuel adjustment expenses have been upheld in many jurisdictions. See Norfolk v. Virginia Electric and Power, 197 Va. 505, 90 S.E.2d 140, 11 PUR3d 438 (1955); City of Chicago v. Illinois Commerce Com’n, 13 Ill.2d 607, 150 N.E.2d 776, 24 PUR3d 334 (Ill.1958), as examples.
The protestants contend that the PSC did not adequately balance industrial and commercial interests versus public interest in reaching its result. Unfortunate as that may be, Federal Power Com’n v. Hope Natural Gas, 320 U.S. 591, 64 S.Ct. 281, 88 L.Ed. 333 (1944), states that the Commission has discretion in working out the balance of interest necessarily involved and that it is not the method, but the result, which must be reasonable. The protestants have not demonstrated that the Commission has abused its discretion in this respect. It is generally conceded that for purposes of computing the average $53 per customer cost, that large industrial customers were being treated the same as individuals or small families, therefore making the estimated average higher than the actual increase that most residential customers would experience.
II. Equal Protection and Special Legislation
The protestants claim that KRS 278.183 violates the constitutional prohibitions against special legislation found in Section 59. Schoo v. Rose, Ky., 270 S.W.2d 940 (1954), provides that a statute must equally apply to all in a class and there must be distinctive and natural reasons for any classification. See also Delta Air Lines v. Revenue Cabinet, Ky., 689 S.W.2d 14 (1985). The Environmental Surcharge Statute satisfies these standards. It is uniform upon the class to which it applies. The class in question is that of electric utilities and not utility costs. The statute does not single out any utility for special treatment. Legislation which applies to and operates uniformly upon all members of any class of persons requiring legislation unique to themselves in the matter covered by the legislation is general and not special or local. Manning v. Sims, 308 Ky. 587, 213 S.W.2d 577 (1948).
The environmental surcharge is not facially unconstitutional or as it is applied by the Commission in this case. We will discuss the effect of retroactivity later in this opinion. It is the responsibility of the General Assembly to determine proper public purposes and to adopt legislation to reach such goals.
Initially, the role of this Court is to determine whether the legislature had a reasonable basis for the legislation sufficient to justify creating a separate classification for certain persons. See Tabler v. Wallace, Ky., 704 S.W.2d 179 (1986). See also Nebbia v. New York, 291 U.S. 502, 54 S.Ct. 505, 78 L.Ed. 940 (1933).
There are distinctive and natural reasons supporting the classification. The legislature sought to give an incentive to use Kentucky coal which in turn would help stabilize the large coal economy for Kentucky. Such a classification is based on distinctive and natural reasons.
There is no constitutional violation based on equal protection under the Kentucky Constitution Sections 2 or 59 or the Federal Constitution.
