Services for Fuel Facility Owners and Operators

About Leak Detection Services

Since the inception of the company in 1987, CGRS has been providing leak detection services to the petroleum and fuel services industries. This makes CGRS the most experienced company in the Western United States offering standard and enhanced leak detection services.

Leak Detection Services

At CGRS, our technicians have discovered over the years that when it comes to leak detection in the fuel delivery and storage industry, no single method or technology performs optimally in every situation. This is why CGRS has purchased, licensed, invented and patented specific technologies to provide solutions for a host of leak detection and delineation solutions.

Moreover, all leak detection technologies employed by CGRS for compliance purposes meet or exceed the required performance and standards created by the regulatory agencies. For example, all technologies employed by CGRS are listed with the National Work Group on Leak Detection Evaluations (NWGLDE). Optional methods include:

Tracer Tight®
This system is ideal for testing larger, high-volume, through-put tanks, either above ground storage tanks (AST) or underground storage tanks (UST). This method can also be used to meet monthly monitoring requirements. Under a special license agreement with Praxair, CGRS uses Tracer Tight® ELD extensively in California for testing sites that are located within 1,000 feet of a well. This method is capable of testing any size tank or pipeline.

iota®
This system, developed and patented by CGRS, has the ability to identify very small leaks and the location of each leak, with unparalleled precision. This method is used for performing quality control testing on new fueling systems before they go into operation. The iota system is used extensively in California for Pre- and Post-Installation ELD testing.

Volumetric / Tank Ullage Test
When appropriate, CGRS utilizes under-fill volumetric tank testing in conjunction with a non-volumetric ullage test. In combination, the two tests accurately measure the entire system. These methods meet required performance standards and are NWGLDE listed.

Volumetric Line Test
CGRS compliance technicians routinely perform volumetric line testing to evaluate product piping for tightness and investigate suspected releases. This method is typically performed at a pressure greater than or equal to 1.5 times operating pressure and has a sensitivity of 0.001 gph.

Leak Detector Function Testing
Regardless of what monitoring method you use on your piping, CGRS can test the function of the system or apparatus to insure that it is properly installed and programmed. In order to confirm that the device meets the required performance standards, CGRS can simulate various size leaks at different pressures with a calibrated leak standards.

Helium Leak Locates
When a suspected release or positive monitoring result has occurred in an operating fueling system, CGRS technicians can locate the problem without excavation. This allows for focused repair by a qualified petroleum contractor. Due to the onset of increased environmental regulations and owner/operator responsibility, within the next 10 years most systems will be double-wall systems with secondary containment. CGRS can even locate a leak in primary piping runs that are in secondary containment, within a few feet. Again, this allows owners and operators the ability to isolate and repair the leak, without extensive excavation—saving you money.
