Gas Stations In Texas: Above Ground Tanks

Gas stations in Texas utilize above ground storage tanks (ASTs) to store fuel. These tanks, which are located above the ground, are subject to specific regulations designed to prevent leaks, protect the environment, and ensure public safety. This article explores ASTs in Texas gas stations, covering regulations, best practices, and more.

Key Takeaways

• Above Ground Storage Tanks (ASTs) are common at Texas gas stations for fuel storage.
• Texas Commission on Environmental Quality (TCEQ) sets stringent regulations for ASTs.
• Regular inspections, maintenance, and leak detection are crucial for compliance.
• Environmental and safety concerns drive these regulations.
• Proper tank selection, installation, and operation are essential for compliance.

Introduction

Across the vast landscape of Texas, gas stations are a familiar sight, providing essential services to drivers. Beneath the surface, or sometimes above it, lies a critical component of these businesses: the fuel storage system. While many gas stations in Texas utilize underground storage tanks (USTs), a growing number are opting for above ground storage tanks (ASTs). This shift is driven by a variety of factors, including regulatory changes, cost considerations, and environmental concerns. Understanding the role, regulations, and best practices surrounding ASTs is essential for both gas station owners and anyone interested in the fuel industry in Texas.

What & Why

What are Above Ground Storage Tanks (ASTs)?

Above Ground Storage Tanks (ASTs) are storage containers that are situated above the ground. These tanks are primarily used to store petroleum products, such as gasoline, diesel, and kerosene, at gas stations. Unlike underground storage tanks (USTs), ASTs are readily visible and accessible for inspection and maintenance. They come in various sizes and configurations, often cylindrical, and are constructed from materials like steel or fiberglass-reinforced plastic.

Why are ASTs Used in Texas Gas Stations?

Several factors contribute to the use of ASTs in Texas gas stations:

• Regulatory Compliance: The Texas Commission on Environmental Quality (TCEQ) has specific regulations for both USTs and ASTs. ASTs may sometimes offer easier compliance pathways.
• Cost: The initial installation costs for ASTs can sometimes be lower than USTs, though this can vary.
• Environmental Concerns: ASTs offer easier leak detection and remediation compared to USTs, potentially reducing the risk of soil and groundwater contamination.
• Accessibility: ASTs are easier to inspect, maintain, and monitor for leaks and corrosion.
• Space Limitations: In areas with high water tables or limited space, ASTs may be a more practical solution.

Benefits of Using ASTs

• Easier Inspection: Visual inspections are straightforward, making it easier to detect potential problems early.
• Faster Leak Detection: Leaks are often easier to identify and contain.
• Reduced Risk of Groundwater Contamination: The containment of spills is typically easier.
• Cost-Effectiveness: May have lower installation costs than USTs.

Risks Associated with ASTs

• Vulnerability to Damage: ASTs are more exposed to weather, vandalism, and accidents.
• Corrosion: ASTs can be subject to corrosion from environmental factors.
• Spills and Leaks: While leak detection is easier, spills can still occur and require immediate cleanup.
• Fire Hazard: ASTs contain flammable liquids, posing a fire risk.

Regulations Governing ASTs in Texas

The Texas Commission on Environmental Quality (TCEQ) is the primary regulatory body overseeing ASTs in Texas. The regulations are in place to prevent releases of petroleum products into the environment and to protect public health and safety. Key areas covered by the regulations include:

• Tank Construction and Design: Tanks must meet specific design and construction standards to ensure structural integrity.
• Secondary Containment: ASTs require secondary containment, such as a concrete or steel containment area, to catch any leaks or spills.
• Leak Detection: Regular leak detection methods are mandated to identify potential leaks promptly.
• Spill Prevention: Measures must be in place to prevent spills during filling and dispensing operations.
• Corrosion Protection: ASTs must be protected against corrosion through coatings, cathodic protection, or other approved methods.
• Recordkeeping: Accurate records of inspections, maintenance, and repairs must be maintained.
• Operator Training: Trained personnel are required to operate and maintain ASTs properly.

How-To / Steps / Framework Application

Steps for AST Installation and Operation

1. Site Selection: Choose a site that meets regulatory requirements, considering factors like distance to property lines, potential for flooding, and accessibility for delivery and maintenance.
2. Tank Selection: Select an AST that meets all regulatory requirements and is appropriate for the type and volume of fuel to be stored.
3. Permitting: Obtain all necessary permits from the TCEQ and local authorities before starting any work.
4. Installation: Install the tank according to manufacturer specifications and regulatory requirements. Ensure proper foundation, secondary containment, and spill prevention measures are in place.
5. Testing: Conduct tests, such as hydrostatic or vacuum tests, to ensure the tank is leak-free after installation.
6. Inspection and Maintenance: Establish a regular inspection and maintenance schedule, including visual inspections, leak detection tests, and corrosion protection checks.
7. Training: Train all personnel on proper AST operation, spill response procedures, and regulatory compliance.
8. Recordkeeping: Maintain detailed records of all inspections, maintenance, repairs, and training.

Framework for Compliance

Compliance with Texas AST regulations involves several key aspects:

• Tank Selection and Installation: Use tanks and equipment that are approved and meet all required standards.
• Containment Systems: Ensure that a proper containment system is in place and maintained.
• Leak Detection: Implement a leak detection program that meets the regulatory requirements.
• Spill Prevention: Take steps to prevent spills during fuel transfer and dispensing.
• Record Keeping: Keep detailed records of all activities, inspections, and maintenance.
• Employee Training: Provide proper training to all personnel who work with the tanks.

Examples & Use Cases

Case Study: Retrofitting a Gas Station with ASTs

A gas station owner in Austin, Texas, decided to replace their aging USTs with ASTs. This was done to reduce the risk of leaks and simplify environmental compliance. The project involved the following steps: — Stimulus Check 2025: What You Need To Know

1. Obtaining permits from the TCEQ and the City of Austin.
2. Selecting and purchasing double-walled ASTs with secondary containment.
3. Hiring a certified contractor to remove the USTs and install the new ASTs.
4. Implementing a leak detection system.
5. Training employees on proper AST operation and spill response.

Benchmarks for AST Performance

• Leak Detection: Implement systems with a proven track record of detecting leaks before environmental damage occurs.
• Corrosion Protection: Use corrosion protection systems like cathodic protection that are proven to extend tank life.
