Cancel permits of quarries posing a risk to petroleum pipeline: environmentalists

Concerns have been raised regarding the proximity of numerous stone quarries to a critical underground petroleum pipeline managed by the Bharat petroleum Corporation Limited (BPCL) in the districts of Karur, Tiruppur, and coimbatore. Environmental advocates are calling on the State government to revoke quarry permits that fall within 500 meters of this pipeline, citing significant safety risks. This pipeline, which transports petroleum products from the Cochin Refinery to key industrial hubs, requires stringent safety protocols to prevent accidents. The issue has gained attention following a Right to Information (RTI) request revealing lapses in adherence to these safety measures. Understanding the regulatory framework and the current compliance status is crucial for ensuring public safety and environmental protection.

Regulatory Framework Governing Pipeline Safety Near Quarries

The underground pipeline operated by BPCL was installed under the legal provisions of the Petroleum and Minerals Pipelines Act,1962,which mandates a strict safety buffer zone of 500 meters around such pipelines. Within this zone, any blasting activities conducted by nearby quarries must follow rigorous guidelines to prevent damage to the pipeline infrastructure. A mandatory pre-work survey by an accredited third-party surveyor is required before blasting,ensuring that the blasting plan incorporates necessary modifications to safeguard the pipeline. One critical parameter monitored is the peak particle velocity (PPV), which must not exceed two inches per second to avoid structural harm. Immediate notification to the pipeline operator is compulsory if PPV levels approach or surpass this threshold.

Standard Operating Procedures and Site-Specific Safety Measures

Beyond the initial survey, quarry operators must develop a detailed procedure qualification record for blasting within the 500-meter safety zone. This document, validated by both third-party surveyors and BPCL officials, outlines the exact number of detonators permissible per blast to maintain PPV limits. Additionally, a comprehensive Standard Operating Procedure (SOP) must be established, tailored to the unique characteristics of each site. Factors such as local topography, soil composition, rock strata, and environmental conditions play a significant role in determining the necessary safety adjustments. These measures are designed to mitigate risks associated with blasting near sensitive pipeline infrastructure.

Current Compliance Challenges in Karur, Tiruppur, and Coimbatore

According to R.S. Mugilan, coordinator of the Tamil Nadu Habitat Protection Movement, many quarries in Karur-including those in Kuppam, Karudayampalayam, Pavithram, and Punnam-are dangerously close to the pipeline. Out of approximately 335 quarries in the district, around 75 are within the 500-meter safety radius. Similar non-compliance issues have been reported in Tiruppur and Coimbatore districts, where quarry operators have neglected to implement the required safety protocols. This widespread disregard for regulations raises serious concerns about potential hazards, including pipeline damage and environmental disasters.

Role of Regulatory Bodies and urgent Government Action

The Tamil Nadu Pollution Control Board and other regulatory agencies have been criticized for inadequate monitoring and enforcement of safety standards around these quarries. Environmentalists emphasize the urgent need for the State government to conduct thorough inspections and ensure strict compliance with BPCL guidelines. Failure to act decisively could result in catastrophic consequences, including pipeline ruptures and subsequent environmental damage. Activists are demanding the immediate cancellation of permits for quarries that fail to meet safety requirements, underscoring the importance of proactive governance in protecting both public safety and natural resources.

Important Facts: Key Points to Remember

• The Bharat Petroleum corporation Limited (BPCL) pipeline runs underground through Karur, Tiruppur, and coimbatore districts, transporting petroleum from Cochin Refinery.
• The pipeline is protected under the petroleum and Minerals Pipelines Act,1962,which mandates a 500-meter safety buffer around it.
• Blasting within 500 meters requires a pre-work survey by an accredited third-party surveyor and a detailed blasting plan.
• Peak particle velocity (PPV) during blasting must not exceed two inches per second to prevent pipeline damage.
• A procedure qualification record and Standard Operating Procedure (SOP) must be developed and approved by BPCL officials and surveyors.
• Site-specific factors such as topography, soil type, and rock strata influence safety measures.
• Approximately 75 out of 335 quarries in Karur are located within the 500-meter safety zone.
• Similar non-compliance issues have been reported in Tiruppur and Coimbatore.
• The Tamil Nadu Pollution Control Board has been criticized for insufficient enforcement of safety regulations.
• environmentalists urge the State government to revoke permits of quarries that do not adhere to safety protocols to prevent potential disasters.

Frequently Asked Questions

Q: Why is the 500-meter safety zone around the BPCL pipeline critically important? The 500-meter buffer is crucial to prevent damage to the pipeline from blasting vibrations and other quarry activities, ensuring the safe transport of petroleum products.

Q: What is peak particle velocity (PPV) and why is it monitored? PPV measures the intensity of ground vibrations caused by blasting.Keeping PPV below two inches per second helps protect the pipeline from structural damage.

Q: Who is responsible for ensuring blasting safety near the pipeline? Quarry operators must conduct surveys and follow SOPs, while BPCL officials and accredited third-party surveyors oversee compliance.Regulatory bodies like the Tamil nadu Pollution Control Board also play a monitoring role.

Q: What actions are recommended if a quarry violates safety protocols? Environmentalists recommend immediate cancellation of permits for non-compliant quarries to mitigate risks of pipeline damage and environmental hazards.

Q: how can site-specific conditions affect blasting safety measures? Factors such as terrain, soil type, and rock formations influence how blasting is conducted, requiring tailored safety procedures to minimize risks near the pipeline.
