PER CURIAM.
This is an injunctive action to prevent defendants from disposing of solid waste generated in Macomb County at a sanitary landfill located in St. Clair County and owned by defendants William Kettlewell, Bill Kettlewell Excavating Company, Inc., and Eastern Michigan Development Company (hereinafter collectively referred to as Kettlewell). A permanent injunction was issued prohibiting solid waste originating in Macomb County from being put in Kettlewell's St. Clair County landfill until the amendment of the two counties' solid waste management plans. In Docket No. 78934, Kettlewell and intervening defendant, The Disposal Company, appeal as of right from that portion of the order enjoining the deposit of solid waste from Macomb County. In Docket No. 79102, plaintiff, the Charter Township of Fort Gratiot appeals as of right from that portion of the injunction which modifies a previously entered consent judgment. The trial court held that the township's ordinance regulating the landfill is preempted by the Solid Waste Management Act, MCL 299.401 et seq.; MSA 13.29(1) et seq.
Kettlewell has been operating a landfill since the sixties. In 1979 the township instituted an injunctive action to limit disposal into the landfill to only demolition materials. The trial court felt that the township's having previously allowed the disposal of other materials estopped them from trying to prevent any further disposal of the same materials. Both parties appealed and while the appeal was pending the parties settled and entered into a consent judgment. The terms allowed Kettlewell to deposit nonhazardous materials allowed *652 under the act, required Kettlewell to comply with the act and the township ordinances, and left the court with continuing jurisdiction.
In June, 1983, The Disposal Company began negotiating with Kettlewell and the South Macomb Disposal Authority for the sale of the site. The township filed a motion to prevent Kettlewell from violating the consent judgment. What Kettlewell would have allegedly violated would have been a DNR rule promulgated pursuant to the act, 1982 AACS, R 299.4711(e)(iii)(C), which provides:
"(e) [Solid waste management] [p]lan selection shall be based on all of the following:

* * *
"(iii) Site requirements, including the following requirements:

* * *
"(C) A site for a solid waste disposal area that is located in one county, but serves another county, shall be identified in both county solid waste management plans."
Apparently the Kettlewell landfill was only mentioned in one county's plan. The court held that requiring both counties to amend their plans to provide for Macomb County waste in St. Clair County landfills was acceptable. Furthermore, the trial judge held that the act preempted any local ordinances and modified the consent judgment.
We first must determine if the trial court erred in ruling that defendants are prohibited from disposing of Macomb County solid waste at the St. Clair County Kettlewell landfill. After a careful review we find no error. We do not find the requirement that both counties' plans mention the landfill to be in error or unreasonable. MCL 299.430; MSA 13.29(30) provides for the DNR to *653 promulgate rules for the development and form of solid waste management plans. 1982 AACS, R 299.4711(e)(iii)(C) provides that a site located in one county but serving another shall be identified in both counties' plans. The counties' plans may be amended to comply with the rules, which would resolve this issue. Defendants' contention that the plan would have to specifically prohibit this is without merit. County plans state what is permitted in the affirmative rather than including an exhaustive statement of what is prohibited. Independence Twp v Shibowski, 136 Mich App 178; 355 NW2d 903 (1984), lv den 422 Mich 853 (1985).
Defendants also argue that the prohibition against depositing Macomb County solid waste in St. Clair County was unconstitutional. The test to determine if this legislation comports with due process is whether or not the legislation bears a reasonable relationship to a permissible legislative objective. Shavers v Attorney General, 402 Mich 554; 267 NW2d 72 (1978), cert den 442 US 934 (1979), after remand 412 Mich 1105 (1982). The challenged legislation is afforded a presumption of constitutionality. We must determine if there is a rational basis for the legislation and if the legislation bears a reasonable relation to the objective. Our review reveals that the legislative objective was to foster comprehensive planning for the disposal of said waste at the local level and to integrate state licensing with those plans so that the disposal of waste within the planning area would be compatible with the local plan. Additionally, enactment of the statutory planning and licensing scheme reasonably relates to the purpose of correcting past planning and licensing inadequacies. By placing primary planning at the county level, the scheme provides for reasoned planning for disposal sites based in part on the county's projected *654 capacities and waste generation rates. Each county is permitted to address local concerns and to adapt its plans to local conditions while at the same time safeguarding parochial decision-making by requiring the plan to be approved for inclusion in the state plan. The rules and the act provide a method whereby a county can develop a plan which is workable and will not be disrupted by future disposal of waste from sources not accounted for during the planning process.
Defendants also contend that the statutory scheme creates two classifications: counties which allow intercounty disposal of solid waste and counties which do not. However, this argument is without merit. All counties wishing to deposit their waste outside their borders are subject to the requirements that the plans of both the depositing and receiving counties so provide in their plans.
Defendants additionally argue that limiting the disposal of waste at the Kettlewell site so diminished the value of the landfill as to constitute a taking of the land by the government. A diminution in property value, standing alone, does not establish a taking. Village of Euclid, Ohio v Ambler Realty Co, 272 US 365; 47 S Ct 114; 71 L Ed 303 (1926). See also Kropf v City of Sterling Heights, 391 Mich 139; 215 NW2d 179 (1974).
Defendants also allege that the Legislature unconstitutionally delegated its power in conferring upon the DNR the authority to promulgate rules and that, furthermore, the DNR has unconstitutionally delegated legislative power because both have failed to articulate adequate standards. In Dep't of Natural Resources v Seaman, 396 Mich 299, 308-309; 240 NW2d 206 (1976), the Supreme Court set forth the following principles to apply herein. The first is that the act should be read as a whole; secondly, the standards should be as reasonably *655 precise as the subject matter requires or permits; and, lastly, the statute should be construed in such a way as to be valid. Our review reveals that the act sufficiently meets these standards.
When the rules are read as a whole it is clear that the standards are as precisely drawn as possible. We find defendant's contentions to be without merit.
Kettlewell argues that the prohibition constitutes an antitrust violation of 15 USC 1, the Sherman Act, which provides in pertinent part that "every contract, combination * * * or conspiracy, in the restraint of trade or commerce among the several states * * * is declared to be illegal." As defendants' activities do not involve interstate commerce or substantially affect interstate commerce, this argument is without merit. McDonald v Saint Joseph's Hospital of Atlanta, Inc, 524 F Supp 122 (ND Ga, 1981).
Next, we must determine if the township ordinances regulating landfill operations are preempted by the act. This issue has been decided in the affirmative in Southeastern Oakland County Incinerator Authority v Avon Twp, 144 Mich App 39; 372 NW2d 678 (1985).
Lastly, the township argues that the trial court erred in modifying the 1981 consent judgment without the consent of the parties. The consent judgment provided for compliance with township ordinances that have been declared preempted. Southeastern Oakland County Incinerator Authority, supra. The trial court is allowed to relieve a party from a judgment if it is no longer equitable that the judgment should have prospective application. GCR 1963, 528.3, now MCR 2.612(c). We find no error in the modification, especially in light of *656 our decision in Southeastern Oakland County Incinerator Authority, supra.
Accordingly, we affirm the decision of the lower court.
Affirmed.
