Keep your service station in compliance with state laws with in-depth inspections from our specialists. Eco Logic Environmental’s inspections include a variety of environmental testing services to keep your gas station compliant. Contact our inspectors today to set up your initial inspection.
Tank Tightness Test
Eco Logic’s technician will arrive on site to evaluate an underground storage tank. The technician will locate the fill pipe. The technician will then check for product and water measurements as well as the depth of the tank, using an oil measuring stick. Eco Logic will shut down the heat, block the vent pipe, and begin testing. The testing will take approximately 30 minutes. The technician will utilize an Estabrook EZY 3 Locator Plus Acoustic Non-Volumetric Tank Tightness Test (vacuum) which is capable of detecting a leak rate of 0.1 gph with a 100% probability of detection and a 1.6% probability of false alarm. This test meets or exceeds the U.S. EPA protocol, 40 CFR Part 280, Subpart D, for Non volumetric tank tightness testing. The Estabrook EZY 3 Locator Plus is capable of determining whether there is leak in the ullage (dry portion) or the wetted (product filled) sections of the tank. The EZY 3 Locator Plus is designed purposely so not do damage on any old or weak tanks. The technician will then turn the heat back on and run the heat for approximately 5 minutes to ensure proper operation was restored.
Corrosion testing will be performed by using a copper sulfite electrode to take a tank to earth potential reading. That reading will be matched up against Steel Tank Institute (STI) and National Association of Corrosion Engineers (NACE) criteria for buried steel tanks to determine the corrosion rate. Eco Logic will determine if the tank has extreme or stray currents, medium to moderate corrosion, acceptable corrosion, or is cathodically protected. This test is not a stand-alone test and must be done in conjunction with tank tightness testing.
GPR (Ground Penetrating Radar)
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks.
GPR uses high-frequency (usually polarized) radio waves, usually in the range 10 MHz to 2.6 GHz. A GPR transmitter emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities, it may be reflected or refracted or scattered back to the surface. A receiving antenna can then record the variations in the return signal. The principles involved are similar to seismology, except GPR methods implement electromagnetic energy rather than acoustic energy, and energy may be reflected at boundaries where subsurface electrical properties change rather than subsurface mechanical properties as is the case with seismic energy.
The electrical conductivity of the ground, the transmitted center frequency, and the radiated power all may limit the effective depth range of GPR investigation. Increases in electrical conductivity attenuate the introduced electromagnetic wave, and thus the penetration depth decreases. Because of frequency-dependent attenuation mechanisms, higher frequencies do not penetrate as far as lower frequencies. However, higher frequencies may provide improved resolution. Thus operating frequency is always a trade-off between resolution and penetration. Optimal depth of subsurface penetration is achieved in ice where the depth of penetration can achieve several thousand metres (to bedrock in Greenland) at low GPR frequencies. Dry sandy soils or massive dry materials such as granite, limestone, and concrete tend to be resistive rather than conductive, and the depth of penetration could be up to 15-metre (49 ft). In moist and/or clay-laden soils and materials with high electrical conductivity, penetration may be as little as a few centimetres.
Ground-penetrating radar antennas are generally in contact with the ground for the strongest signal strength; however, GPR air-launched antennas can be used above the ground.
