N.C. Dep't of Envtl. Quality v. TRK Dev., LLC, 259 N.C. App. 597

TRK Development owned three contiguous parcels and sought DEQ approval in 2014 for erosion and sedimentation control plans to build a warehouse addition that required excavating soil from a second parcel.
TRK’s civil engineer submitted plans (including soil borings showing buried trash) to DEQ’s Land Quality Section; DEQ issued two Letters/Certificates of Plan Approval expressly limited to erosion and sedimentation control and stating the approval did not supersede any other permit.
After construction began, DEQ’s Solid Waste Section inspected following an anonymous tip and discovered excavated waste being placed on the third parcel; DEQ informed TRK no solid waste permit had been issued and directed removal to a permitted landfill.
DEQ issued a Notice of Violation and later a Compliance Order alleging TRK operated an unpermitted open dump in violation of solid waste regulations and assessed an administrative penalty. Soil tests later showed hazardous contaminants.
An ALJ overturned DEQ’s Compliance Order, holding DEQ estopped from enforcement because it previously approved TRK’s erosion/sedimentation plans; the superior court affirmed. DEQ appealed and the Court of Appeals reversed.

Issue	Petitioner (DEQ) Argument	Respondent (TRK) Argument	Held
Whether equitable estoppel can bar enforcement of the Solid Waste Management Act by a state agency	Estoppel cannot impair exercise of governmental/police powers; DEQ must enforce the Act regardless of prior limited approvals	DEQ’s prior issuance of erosion/sediment approvals led TRK to reasonably rely on DEQ and be estopped from later enforcement	Estoppel cannot be applied to prevent DEQ from exercising its police power to enforce the Solid Waste Management Act; ALJ and trial court erred
Whether elements of equitable estoppel were met	DEQ’s approvals were limited to erosion control, contained disclaimers, and did not falsely represent compliance with solid waste law; TRK had means to know requirements and acted without reasonable care	TRK relied on DEQ approvals (and plan borings showing trash) and lacked notice that a separate solid waste permit was required; reliance was reasonable	The approvals did not constitute a representation that TRK’s disposal complied with solid waste law; TRK’s reliance was unreasonable and estoppel elements were not satisfied
