How to Dispose of a Chemical Storage Tank

Customers often ask us how to dispose of a chemical storage tank once it has reached the end of its useful life. Even though we do not offer disposal services, we can offer you guidance for proper chemical tank disposal. Here is the fundamental information you need to know before you haul away your polyethylene chemical storage tank.

Your Tank Is Hazardous Waste

Most states have a “Cradle to Grave” law, which applies to used chemical storage conatiners and hazardous waste. The law states that once you put a chemical into a tank, you, as the tank owner, are responsible for that tank forever—no matter what happens to the tank. Remember, this notion still holds true even after the tank is retired from use.

In most cases, you can’t simply cut up a tank and put it in a landfill. Instead, we recommend that you contact your local, state, or federal OSHA or EPA office to get instructions on how to dispose of your tank. The instructions can be specific to the tank and the chemical being stored, so you will probably need to contact the regulatory office each time you need to dispose of a tank.

When contacting OSHA or the EPA, be prepared to give them the chemical name and tell them how clean the tank is. Unless your tank is completely chemical-free, it will most likely be considered as hazardous waste. The regulatory office will determine whether the tank needs to go to a standard landfill,hazardous waste landfill, or possibly can be recycled.

Hauling the Chemical Tank

Prior to moving the tank, contact the landfill to discuss specific handling requirements. Many landfills won’t accept storage tanks unless they have been cut up, so it is better to know the specific requirements in advance.

In almost all cases, tanks and containers must be emptied of chemicals and sludge before disposal or recycling, and they must be cleaned to a vapor-free condition. We recommend hiring a professional hazardous waste disposal company to disinfect, cut up, and haul off your tank. There are several of these companies throughout the United States that are equipped to provide expert service. These companies will come out to your site to clean the tank, handle any remaining chemical, and may provide a temporary rental tank if needed. Often, your OSHA or EPA office can recommend a local company.

Dispose of Your Tank with Confidence

When it comes time to retire your chemical storage tank, be sure you know what your local and state laws require. Follow these guidelines to ensure that you handle tank disposal ethically and legally
