Every day in Cebu, the equivalent of 500 dump trucks of limestone leaves the province’s quarry sites. Over a year, that amounts to roughly 3.6 million tons of limestone—enough trucks lined up bumper to bumper to stretch from Cebu to Manila and back.

Yet a recent tax dispute between the Province of Cebu and Apo Land and Quarry Corporation ended with a compromise settlement of Php211.56 million, far lower than the original Php1.218 billion assessment. The tax dispute arose from differing interpretations of the province’s authority to impose quarry extraction taxes.

At first glance, the reduction appears dramatic. But the outcome reflects an important legal reality: the taxing powers of local governments are limited by national law and Supreme Court jurisprudence.

Understanding the Apo quarry case therefore, requires looking beyond the headline numbers. It reveals how law, economics, and natural resource governance intersect in a rapidly developing province like Cebu.

According to reports, the Province of Cebu initially assessed Apo Land and Quarry Corporation approximately Php1.218 billion in quarry-related taxes, fees, penalties, and interest covering operations from around 2006 to 2022. After legal review, the assessment was recalculated and reduced to a proposed Php211.56 million compromise settlement, leaving a difference of roughly Php1.006 billion. When this proposed settlement is spread across the coverage period, the provincial recovery corresponds to roughly Php13.2 million per year. The compromise, however, is not yet final and is currently under review by the Cebu Provincial Board, which must decide whether the negotiated settlement should be approved.

The Cebu Quarry Ledger

One way to understand the Apo quarry case is to view it through a simple economic ledger that compares physical extraction, economic value, and fiscal recovery.

Category	Indicator	Approximate Value
Physical extraction	Limestone production	~3.6 million tons per year
Logistics equivalent	Dump truck loads	~180,000 trucks per year
Daily extraction	Truck equivalent	~500 trucks per day
Production value	Quarry output	~₱225 million per year
Provincial recovery	Settlement equivalent	~₱13.2 million per year
Fiscal capture ratio	Provincial share	~6%

The reduction of the assessment was largely driven by the legal limits of provincial taxation powers. Provincial governments derive their authority to levy quarry taxes from the Local Government Code of 1991, which allows provinces to impose taxes on sand, gravel, and other quarry resources extracted from public lands or public waters. Apo Land and Quarry Corporation operates limestone quarries under Mineral Production Sharing Agreements (MPSAs) issued by the national government pursuant to the Philippine Mining Act of 1995. The Supreme Court clarified the limits of provincial quarry taxation in Province of Bulacan v. Court of Appeals (G.R. No. 126232, 1998), ruling that provinces cannot impose quarry extraction taxes on minerals extracted from private lands covered by mining agreements. Because part of the original Cebu assessment involved such extraction taxes, those components could not be legally sustained. Once they were removed, the remaining obligations consisted mainly of monitoring fees, environmental charges, penalties, and interest.

To appreciate the scale of quarry operations in Cebu, it helps to examine limestone production data. According to records of the Mines and Geosciences Bureau, Cebu produces roughly 3.6 million metric tons of limestone annually. Production reached about 3.91 million tons in 2022, 3.47 million tons in 2023, and 3.62 million tons in 2024, for a total of roughly 11 million tons of limestone extracted over three years.

Apo’s reported production value has been approximately:

Php225 million per year.

Compared with the provincial recovery under the proposed settlement:

Indicator	Amount
Annual production value	~Php225 million
Average provincial recovery	~Php13.2 million
Estimated fiscal capture	~6%

It should be noted that other taxes—such as corporate income tax and excise tax on minerals—are collected by the national government, not by the province.

The Apo case highlights a structural feature of Philippine resource governance.

Numbers of this scale can be difficult to visualize. If a typical quarry dump truck carries 20 tons of limestone, Cebu’s annual limestone production would require approximately 180,000 truckloads per year. Spread across the year, this corresponds to roughly 500 dump trucks of limestone leaving quarry sites every single day. If these trucks were lined up bumper to bumper, the line would stretch approximately 1,440 kilometers, roughly the distance from Cebu to Manila and back.

The production value associated with these operations is also significant. Apo’s reported quarry production value has been approximately Php225 million annually. When compared with the proposed provincial recovery under the compromise settlement—about Php13.2 million per year—the province’s fiscal capture represents roughly six percent of the reported production value. It should be noted, however, that other taxes such as corporate income taxes and mineral excise taxes are collected by the national government, not by the province.

The Apo case illustrates a structural feature of Philippine resource governance. Mineral resources are owned by the State and administered by the national government through mining agreements and permits. While extraction activities occur within provinces and municipalities and may have local environmental and land-use implications, the authority to regulate mining operations and collect major fiscal revenues largely rests with the national government. As a result, extraction occurs locally, environmental impacts are experienced locally, but taxation authority may be limited locally.

The compromise settlement in the Apo case therefore highlights a broader issue in how the economic value of natural resources is measured and governed. Taxes capture only part of the economic activity associated with extraction, and they often do not reflect the environmental systems that support development. This is precisely the gap addressed by the Philippine Ecosystem and Natural Capital Accounting System Act, which institutionalizes ecosystem and natural capital accounting in the Philippines. Natural capital accounting provides a framework for recognizing ecosystems—such as watersheds, forests, and karst landscapes—as economic assets that contribute to long-term development.

For provinces like Cebu, where quarrying occurs in upland landscapes and watershed areas, natural capital accounting can provide a more comprehensive understanding of the economic context in which resource extraction takes place. While taxation remains an important fiscal tool, ecosystem accounting helps policymakers recognize the value of environmental systems that sustain communities and economic activity.

As the Provincial Board reviews the proposed compromise settlement, the decision involves more than simply approving a negotiated amount. The board must weigh the legal sustainability of the original assessment, the fiscal risks of continued litigation, the potential precedent that a settlement may create for other cases, and the broader need to strengthen governance of natural resources within the province.

The Apo quarry tax case is therefore not merely about the reduction of a tax assessment from Php1.218 billion to Php211 million. It reflects the complex interaction between national control of mineral resources and local responsibility for land use and environmental management. As Cebu continues to grow as an economic center in the Visayas, the challenge will be to ensure that resource extraction contributes to development while maintaining responsible stewardship of the landscapes that sustain communities and ecosystems.

The lesson of the Apo case is that while taxes measure the revenue generated from extraction, natural capital accounting helps us understand the value of the landscapes from which those resources are taken.

The dynamics of quarry extraction also raise a broader political-economic question. While limestone extraction generates private economic returns for firms and supports industrial production, the environmental risks associated with landscape modification—such as altered drainage patterns, erosion, and increased flood vulnerability—are often experienced downstream. In many resource economies, economic gains from extraction are concentrated at the site of production, whereas environmental risks, such as flooding, may be borne by downstream communities.
