Once all the accessible components with leaks are repaired, LDT can begin testing <br /> the underground portion of the system. <br /> 3. Testing: <br /> a. A different chemical Tracer is introduced into the tank and piping. <br /> b. This second chemical tracer is then pumped throughout the systems product, vent, <br /> and vapor return piping as applicable. <br /> c. Each component is tested at the working pressure of the individual component. <br /> d. Once the primary component is pressurized with the chemical tracer gas the <br /> secondary containment surrounding the primary containment can be sampled <br /> e. If the chemical tracer is found in the secondary containment sample a leak is <br /> declared and the leak location will be identified. <br /> 4. Spill Bucket Testing: <br /> a. Spill Buckets are pneumatically tested. A leak rate is calculated and could indicate <br /> a leak within the spill bucket. <br /> b. If a leak is detected the contractor will be directed to the leak and a repair of the <br /> spill bucket will be completed. <br /> Reporting: <br /> 1. Reports consist of a two page written document summarizing the data collected at each <br /> site. <br /> 2. Each component in the system is listed and certified individual. <br /> 3. Owners, contractors, inspectors and regulators are invited to contact LDT for <br /> specifications regarding MDleak® test methods. <br /> References: <br /> 4.
