h. Business name of tank testing company. <br />i. Mailing address of tank testing company. <br />j. Printed and signed name of person certifying test. <br />3. Report of Test Procedures and Results: Provide for each tank tested. Include the following <br />information: <br />a. Construction, shape, capacity of tank; length of connected piping. <br />b. Tank contents and coefficient of thermal expansion for fluid present in tank during test. <br />c. Type of pump (e.g., turbine, suction, remote) associated with each tank. <br />d. Statement regarding presence or absence of a Stage H vapor recovery system. <br />e. The depth to groundwater (if known to be less than 15 feet). <br />f. The complete system test shall include a high level test (associated piping and tank) and a low level <br />test if required. Low level test is waived if high level test results indicate that system is tight. <br />Liquid level for low level test: approximately one inch above fill line bung. <br />4. Testing Procedure Used: <br />a. Enter individual steps taken as a part of test on a log. Typical entries may include, but are not <br />limited to: Topping off tanks, start up test, temperature calibration, and level readings. <br />b. Include time and date test started, time of each log entry, and completion time of test. Use 24-hour <br />clock format. <br />c. Explain any special procedures used as part of, or conditions to, test. <br />d. Describe any repairs made to piping system during test. <br />S. Format of Test Results: <br />a. Describe final results for each test in terms of: <br />1) Tank: A numerical leak rate expressed in units of gallons per hour. <br />a) Express rates as a loss (-) or gain (+) of product. <br />b) Isolate tank leak rate and include with hydrostatic/pneumatic piping system test data. <br />2) Piping System: A numerical leak rate expressed in units of gallons per hour. <br />a) Include hydrostatic/pneumatic pressure applied to system and time elapsed prior to <br />depressurization. <br />3) Indeterminate Leak Rates: That cannot be isolated to storage tank or piping system (system <br />leaks) will not be recognized as conclusive. <br />6. Inconclusive or Suspended Test: <br />a. Include reason(s) with tank tester's recommendations. <br />b. Notify responsible representative verbally within 24 hours. <br />c. Submit a written report to Contractor and Division of the State Architect field inspector and to <br />Project Engineer. Final decision shall be made by the Project Engineer. <br />3.05 PIPING <br />A. Application: <br />1. Fuel: Double -walled fiberglass, unless specified otherwise. <br />a. Vent Piping: Schedule 40 black steel pipe with screwed fittings six inches above grade. <br />UNDERGROUND FUEL STORAGE TANK <br />070601:HTL:lc:cw 13215 - 22 CH 107517 / 1075 1 S <br />
