By: Curren Environmental Introduction Historically, home heating oil has been stored in Underground Storage Tanks, USTs. In response to both State and Federal environmental requirements and emerging technology the replacement of single wall steel UST's have become a growing trend in order to remove the environmental liabilities associated with Leaking Underground Storage Tanks, (LUSTs). Buried oil tanks raise a variety of environmental, safety, legal and economic concerns for home owners and home buyers. The largest concern relates to the environmental issues that are caused when the oil tank leaks and causes soil or groundwater contamination. Curren Environmental will remove your oil tank the right way and eliminate the worries. The following is a breakdown of the proper steps that should taken in order to remove your residential oil tank. If you have a buried underground oil tank, installed at a residential property, your oil tank is exempt from Federal Regulations. Step 1: Permitting Prior to any excavation for the purpose of removing an underground oil tank, local construction/ Step 2: Underground Utilities State law requires that before any excavation activities can commence, a utility markout will need to be performed. The company performing the oil tank removal should call for an underground markout through “NJ One Call”. Not all underground utilities are covered by this service. Also, utility markouts do not include portions of service lines which are the property owner's responsibility to maintain. It is the responsibility of the property owner to identify all underground utilities which may not be covered by the markout service. It is the law in New Jersey and other states, to call for a utility markout before you dig. Make sure the company you choose to remove the tank obtains a markout confirmation number. It protects all parties involved. Step 3: Oil Tank Cleaning After the overburden soils have been excavated to expose the top of the oil tank, a hole will be cut into the tank so that all pumpable liquids can be removed. The tank should be purged of all petroleum vapors. After the pumping liquids have been removed the tank will be entered and cleaned. Cleaning of the tank will consist of wiping, squeegeeing and removing all liquids and sludges from the tank. Liquids are then either placed into onsite storage containers or a vacuum truck. The liquids are then typically transported off the site for recycling. The tank should only be removed from the ground after it has been properly cleaned. American Petroleum Institutes "Recommended Practice 1604, Removal and Disposal of Used Underground Petroleum Storage Tanks" and American Petroleum Institute Publication 2015, "Cleaning Petroleum Storage Tanks,” establish standard industry protocol which should be followed during all tank closure activities. Please make sure the company removing the tank is aware of and follows these standards. Step 4: Oil Tank Removal The majority of oil tanks are typically located adjacent to an existing structure or dwelling, and thus the excavation of oil tank should be made with due care to avoid undermining the foundation of the structure. The depth of an excavation for removing a given oil tank will be determined by the diameter of the oil tank and depth of cover material. Size of excavation will be based on the dimensions of the oil tank. As a general rule, over excavation of a tank hole will include a 18" to 24" foot print around the perimeter of the oil tank itself. It is recommended that all oil tanks be removed from the ground when taking a tank out of service. (In some instances when removal of the oil tank may damage the integrity of the structure an abandonment in place can be performed.) By removing the tank from the ground a site assessment can be performed to determine if the tank has maintained integrity. Step 5: Oil Tank Site Assessment After the oil tank is removed a site assessment can performed by Curren’s certified NJDEP Subsurface Evaluator. The site assessment to evaluate whether contamination is present in the excavation can be carried out in a variety of ways while the tank is being removed. ▸ Evidence of contamination can be determined from product odors, product stained soils, and/or visual evidence of free product. ▸ Inspection of the Underground Storage Tank, (UST), for evidence of corrosion or perforations. ▸ By a series of observations and measurements during the tank excavation and decommissioning operations such as soil and ground water sampling and analysis. In New Jersey the standard analytical testing method for #-2 heating oil is Diesel Range Organics (DRO). All samples must be submitted to an independent NJDEP licensed laboratory for analysis. DRO results are measured in part per million or ppm. Samples results above 5,100 ppm are actionable and require remedial activities to be completed. DRO results between 1,000 ppm and 5,100 ppm require an additional analysis. In New Jersey, if evidence of a release of contaminants is confirmed by any of the above methods, the New Jersey Environmental Action Hotline must be called and the release reported. Step 6: Backfilling Once the tank is removed from the ground the void space must be backfilled with clean certified fill. The general equation for backfilling is five cubic yards of backfill material for every 1000 gallons of storage capacity. For example a 500-gallon tank would require 2.5 cubic yards of fill material. Suppling and installing the backfill is always performed by the firm removing the tank and should be included in tank removal cost. Step 7: Site Investigation Report Curren Environmental will prepare a Site Investigation Report which will document the tank removal activities. The report will detail the heating oil tank removal and provide certification of the tank removal. The report will include the following information: 1. Copy of the local permit for tank removal 2. Liquid receipt from the tank cleaning. 3. A thorough written description of the tank removal activities. 4. Photo documentation of tank removal (if available). 5. A copy of the tank scrap receipt. 6. Any applicable laboratory test results. 7. A detailed text description of the condition of the tank and if any petroleum contamination was noted in the tank excavation. Curren Environmental, Inc. is a licensed by the New Jersey Department of Environmental Protection (NJDEP) to perform closure activities associated with Underground Storage Tanks, (USTs). The company is composed of a variety of skilled professionals with expertise ranging from engineering to environmental management. # # # About Curren Environmental: End
