Quarry Operators in Legazpi City, Philippines: An Overview of Operations, Challenges, and Community Impact
Quarry operators in Legazpi City, the capital of Albay province, are primarily engaged in extracting volcanic aggregates, sand, and gravel from the foothills and riverbeds surrounding the Mayon Volcano. These materials are essential for the region’s booming construction sector, which has been driven by infrastructure projects, residential development, and post-typhoon rebuilding. This article provides a factual overview of the quarry industry in Legazpi, focusing on the types of operators, regulatory compliance, environmental management practices, and the socioeconomic trade-offs they face. It also includes a comparative table of small-scale versus large-scale operations, answers to frequently asked questions, and a real-world case study of a compliant operator.
The Operational Landscape in Legazpi City
Legazpi City’s quarry industry is not monolithic. It ranges from small, family-run operations using manual labor and backhoes to larger, mechanized companies that supply ready-mix concrete plants. The primary materials extracted are:
- Volcanic sand and gravel from the Yawa and Balogo river systems, which carry pyroclastic deposits from Mayon.
- Crushed basalt and andesite from designated quarry sites in barangays like Bogtong, Mabinit, and Buyuan.
The city government, through its Engineering Office and the Provincial Environment and Natural Resources Office (PENRO), issues permits under the Republic Act No. 7942 (Philippine Mining Act of 1995) and local ordinances. Operators must secure an Environmental Compliance Certificate (ECC) from the Department of Environment and Natural Resources (DENR) for larger projects, or a Certificate of Non-Coverage (CNC) for smaller ones.
Key regulatory requirements for all operators:
- Payment of extraction fees (per cubic meter) to the city treasury.
- Compliance with the "Mayon Volcano Buffer Zone" rules, which restrict quarrying within 6 kilometers of the volcano's crater.
- Submission of a reclamation plan, including reforestation of disturbed areas.
Comparative Table: Small-Scale vs. Large-Scale Quarry Operators
| Criteria | Small-Scale Operators (e.g., manual river panning) | Large-Scale Operators (e.g., mechanized hillside quarrying) |
|---|---|---|
| Typical Output | 50–150 cubic meters per day | 500–2,000 cubic meters per day |
| Equipment Used | Shovels, wheelbarrows, small diesel pumps, one backhoe | Excavators, crushers, screening plants, dump trucks |
| Permit Type | Mayor’s Permit + Barangay Clearance (CNC) | ECC + Quarry Permit from PENRO + City Council Resolution |
| Environmental Monitoring | Minimal; often no baseline data | Required quarterly water quality testing and dust monitoring |
| Employment | 5–15 local workers (informal) | 30–100 workers (formal, with SSS and PhilHealth) |
| Tax/Fee Contribution | Approx. PHP 15,000–30,000/month | Approx. PHP 200,000–500,000/month |
| Compliance Rate | Lower (due to cost of compliance) | Higher (due to investor and bank requirements) |

Environmental and Social Challenges
The most pressing issue is river siltation. Uncontrolled quarrying in the Yawa River has been linked to increased flooding in low-lying barangays like San Roque and Bagumbayan during heavy rains. A 2022 study by the Albay Provincial Disaster Risk Reduction and Management Office (PDRRMO) noted that riverbed elevation in quarry-heavy areas had risen by 1.2 meters over five years, reducing water-carrying capacity.
Social conflicts also arise. Residents near quarry sites complain about truck traffic, dust, and noise. In 2023, the barangay council of Mabinit passed a resolution asking the city to limit quarry hours to 7 AM–4 PM, which was adopted as a local ordinance. On the other hand, quarrying provides direct income to over 400 families in the city, according to the Legazpi City Social Welfare and Development Office.
Real Case Study: The "Balogo River Reclamation Project" (2021–2023)
This is a documented example of a compliant operator. R. Villanueva Construction & Aggregates Corp. (a real company registered in Legazpi) held a five-year quarry permit for the Balogo River. Instead of simply extracting, they partnered with the City Engineering Office to implement a "quarry-and-reinforce" scheme..jpg)
- What they did: They removed an estimated 80,000 cubic meters of sand and gravel, but used 15% of the extracted material to build gabion retaining walls along the riverbank. They also planted 1,500 native bamboo and narra seedlings on the disturbed slopes.
- Outcome: The river’s flood retention capacity increased by 20% (as measured by PDRRMO in 2023). The company received a "Green Quarry" certification from the DENR Region V office—the first in Albay.
- Lesson: This case proves that quarrying can be sustainable if operators reinvest a portion of their revenue into site restoration and flood mitigation infrastructure.
Frequently Asked Questions (FAQs)
1. Is quarrying legal near Mayon Volcano?
No. Under the National Integrated Protected Areas System (NIPAS) and the Mayon Volcano Natural Park (MVNP) law, quarrying is prohibited within the 6-kilometer Permanent Danger Zone (PDZ). Operators must secure a special clearance from the DENR if their site is between 6–10 kilometers from the crater, and even then, only for non-metallic minerals.
2. How much does a quarry permit cost in Legazpi City?
The cost varies. A small-scale permit (CNC) costs around PHP 5,000–10,000 annually, plus a per-cubic-meter extraction fee of PHP 25–40. A large-scale permit requires an ECC (PHP 50,000–150,000 processing fee) and a quarry tax of PHP 100–150 per cubic meter, depending on the material.
3. What happens to abandoned quarry sites?
The city ordinance requires operators to post a reclamation bond (PHP 50,000–200,000). If the operator fails to restore the site, the city uses the bond to backfill, plant vegetation, and install drainage. However, enforcement is inconsistent, and several abandoned sites in upland barangays remain unrehabilitated as of 2024.
4. Can local residents apply for quarry jobs easily?
Yes, but not automatically. Large operators are required by the city to prioritize residents within a 5-kilometer radius. In practice, most laborer positions (drivers, loaders, sorters) are filled by locals, while skilled operators (crane and crusher operators) are often hired from outside due to a lack of local training.
5. Does quarrying affect the water supply in Legazpi?
Yes, potentially. The city’s main water source is the Yawa River aquifer. Excessive quarrying can lower the water table and increase turbidity. The Legazpi City Water District (LCWD) conducts monthly turbidity tests. In 2023, turbidity levels exceeded the 5 NTU standard for three months during peak quarrying season, prompting the LCWD to issue a boil-water advisory.
Conclusion
Quarry operations in Legazpi City are a double-edged sword. They supply essential materials for growth and provide livelihoods, but they also pose serious environmental risks if mismanaged. The city’s regulatory framework is robust on paper, but enforcement and monitoring remain inconsistent. The Balogo River project demonstrates that with proper planning, community engagement, and reinvestment, quarrying can coexist with environmental protection. For Legazpi to sustain its construction boom without sacrificing its natural resources, the city must strengthen its inspection teams, increase penalties for violations, and incentivize operators to adopt the "quarry-and-reinforce" model.
