Quick Answer
Installing a buried propane tank can contaminate groundwater, cause soil erosion, and contribute to greenhouse gas emissions. The tank's buried location makes it prone to damage from roots, pests, and accidental excavation. Proper installation and maintenance can mitigate these risks.
Environmental Risks
Buried propane tanks pose significant environmental risks, primarily linked to groundwater contamination and soil erosion. Propane leaks can seep into the surrounding soil and groundwater, posing a threat to local ecosystems and human health. According to the U.S. Environmental Protection Agency (EPA), a single gallon of leaked propane can contaminate up to 750,000 gallons of groundwater. Regular inspections and maintenance can minimize this risk.
Soil Erosion and Tank Damage
Soil erosion around buried propane tanks can lead to structural damage and compromise the tank’s integrity. Tree roots, pests, and accidental excavation can cause damage, increasing the risk of propane leaks. To mitigate this risk, it’s essential to install the tank at least 10 feet away from any water source and 5 feet away from any property line, as recommended by the National Fire Protection Association (NFPA). Additionally, using a root-resistant liner or coating can help protect the tank from damage.
Greenhouse Gas Emissions
Propane, a fossil fuel, contributes to greenhouse gas emissions when stored in a buried tank. The EPA estimates that propane storage and transportation account for approximately 1.5% of the United States’ total greenhouse gas emissions. To reduce this impact, consider using renewable energy sources, such as solar or wind power, to supplement or replace propane usage. Properly maintained and efficient propane tanks can also minimize emissions.
