January 10, 2012 1 Volume 61 No. 1 Zoning Bulletin <br />The court explained that there are three generally recognized types of <br />preemption: "a) express or explicit preemption, where the statute in- <br />cludes a preemption clause, the language of which specifically bars local <br />authorities from acting on a particular subject matter; (2) conflict preemp- <br />tion, where the local enactment irreconcilably conflicts with or stands as <br />an obstacle to the execution of the full purposes of the statute; and (3) <br />field preemption, where analysis of the entire statute reveals the General <br />Assembly's implicit intent to occupy the field completely and to permit no <br />local enactments." "Both field and conflict preemption require an analysis <br />of whether preemption is implied in or implicit from the text of the whole <br />statute, which may or may not include an express preemption clause," said <br />the court. <br />To determine whether there was preemption here, the court analyzed <br />the statutory language in the Surface Mining Act's preemption provision. <br />It found the first sentence of the preemption clause applied to local en- <br />actments already in existence at the time the Surface Mining Act took ef- <br />fect. Since the Ordinance was enacted after the effective date of the Surface <br />Mining Act, the first sentence of the preemption clause did not apply here. <br />The court found the second sentence of the preemption clause did in- <br />tend to bar local authorities from enacting regulations of "surface mining" <br />after the effective date of the Act, as that term was defined under "surface <br />mining activities." The court noted that missing from the Surface Mining <br />Act's definition of "surface mining activities" was any mention whatsoever <br />of either the location of surface mining or traditional land use regulation. <br />The court ultimately concluded: "The Surface Mining Act's preemption <br />clause expressly preempts the regulation of surface mining; however, the <br />clause does not preempt local regulation of land use via zoning ordinances, <br />which may affect where surface mining is located or sited." Thus, conclud- <br />ed the court, the Township Ordinance's residential setback provision for <br />mining activities fell clearly within the purview of traditional zoning regu- <br />lations, merely regulating where surface mining can be sited, and therefore <br />was not expressly preempted by the preemption clause of the Surface Min- <br />ing Act. <br />Hoffman Mining had also argued that, if not expressly, the General <br />Assembly had, in the Surface Mining Act's preemption clause, implicitly <br />intended to preempt local enactments, such as the zoning ordinance's set- <br />back provision. The court disagreed. Such implicit preemption would re- <br />quire both conflict preemption and field preemption, and the court found <br />neither here. <br />The court found that there was no conflict preemption between the Or- <br />dinance setback provision and the Surface Mining Act setback provision of <br />300 feet; it was possible to comply with both setback provisions. Moreover, <br />the Ordinance's residential setback provision did not "stand as an obstacle <br />to the execution of the full purposes and objectives of the Surface Mining <br />Act" which were: "to provid[e] for the conservation and improvement <br />of areas of land affected in [ ] surface mining "; and "the protection and <br />maintenance of the water supply." Moreover, the court did not interpret the <br />Surface Mining Act "to have removed all force from general zoning consid- <br />6 © 2012 Thomson Reuters <br />
