What Constitutes Petroleum Under the APSA - Above Ground Petroleum Storage Act
Petroleum storage regulations play a crucial role in protecting the environment and public safety. The Above Ground Petroleum Storage Act (APSA) sets clear standards for handling and storing petroleum products. But what exactly counts as petroleum under this law? Understanding the definition is essential for businesses, regulators, and environmental professionals to ensure compliance and avoid penalties.
This post breaks down the APSA’s definition of petroleum, explains its scope, and highlights practical examples. Whether you manage fuel tanks, operate a gas station, or work in environmental compliance, this guide will clarify what substances fall under the APSA and why it matters.
What the APSA Above Ground Petroleum Storage Act Covers
The APSA was created to regulate the safe storage of petroleum products above ground. Its main goal is to prevent leaks, spills, and contamination that can harm soil, water, and air quality. The law applies to storage tanks and containers holding petroleum in various forms.
The act defines petroleum broadly to capture a wide range of substances derived from crude oil. This helps ensure that all potentially hazardous materials are managed responsibly.
Defining Petroleum Under APSA
According to the APSA, petroleum includes:
Crude oil in its natural state
Refined petroleum products such as gasoline, diesel, jet fuel, kerosene, and heating oils
Petroleum-based liquids including lubricants, solvents, and certain chemical feedstocks
Mixtures containing petroleum hydrocarbons
The law does not limit petroleum to just fuels. It covers any liquid derived from crude oil that can pose environmental risks if released.
Key Characteristics of Petroleum in APSA
Hydrocarbon-based: Petroleum products are primarily hydrocarbons, meaning they consist of hydrogen and carbon atoms.
Flammable or combustible: Most petroleum liquids can ignite or burn, which is why storage safety is critical.
Liquid state: The act focuses on liquids stored above ground, though some vapors and gases related to petroleum may also be regulated under other laws.
Examples of Petroleum Covered by APSA
To clarify, here are some common substances considered petroleum under the act:
Gasoline: Used as fuel for vehicles, stored in tanks at gas stations.
Diesel fuel: Used in trucks, generators, and machinery.
Jet fuel: Aviation fuel stored at airports and maintenance facilities.
Heating oil: Used in residential and commercial heating systems.
Lubricating oils: Engine oils and industrial lubricants.
Kerosene: Used for heating, lighting, and cooking in some regions.
Petroleum solvents: Chemicals used in manufacturing and cleaning.
These examples show the variety of petroleum products regulated by APSA. Even small quantities stored above ground must meet safety standards.
What Is Not Considered Petroleum Under APSA
Some substances are excluded from the APSA petroleum definition, including:
Non-petroleum-based fuels like ethanol or biodiesel (unless mixed with petroleum)
Gaseous fuels such as natural gas or propane stored in pressurized tanks
Solid hydrocarbons like coal or tar sands
Water or other non-hydrocarbon liquids
Understanding these exclusions helps businesses determine if their storage falls under APSA or other regulations.
Why the Definition Matters for Compliance
Knowing what counts as petroleum under APSA affects several areas:
Storage requirements: Tanks must meet design, construction, and maintenance standards.
Spill prevention: Operators must implement measures to prevent leaks and contain spills.
Reporting and inspections: Facilities must report storage volumes and allow regulatory inspections.
Cleanup responsibilities: In case of a spill, owners must follow cleanup protocols to protect the environment.
Failing to recognize a substance as petroleum can lead to non-compliance, fines, and environmental damage.
Practical Tips for Businesses Handling Petroleum
Identify all stored liquids: Review your inventory to classify substances correctly.
Check product labels and safety data sheets: These documents often indicate if a product is petroleum-based.
Consult local regulations: APSA definitions may vary slightly by jurisdiction.
Maintain proper storage equipment: Use tanks and containers certified for petroleum storage.
Train staff: Ensure employees understand what petroleum is and how to handle it safely.
Environmental and Safety Implications
Petroleum spills can contaminate soil and groundwater, harm wildlife, and pose fire hazards. The APSA’s broad definition ensures that all relevant substances are managed to reduce these risks.
For example, a leaking diesel tank at a construction site can pollute nearby water sources. Proper classification and storage under APSA help prevent such incidents.
Summary
The APSA Above Ground Petroleum Storage Act defines petroleum broadly to include crude oil, refined fuels, lubricants, and other hydrocarbon liquids. This wide scope ensures that all potentially hazardous petroleum products stored above ground are regulated for safety and environmental protection.
