The tank owner is required to have an SIR report for each month [Section 2643 (b)(3) CCR']. <br />2. Monthly reports must be submitted to the local agency upon request [Section 2712 (b) CCR]. <br />3. The tank owner is required to have the report by the 20th day of the following month [Section 2646.1 (c) CCR). <br />4. If for any reason, the test is neither "pass" nor "fail", the "inconclusive column must be marked. <br />5. The local agency must be notified of a tank that does not pass the SIR test within 24 hours of receipt of the report and the SIR report must be <br />submitted to the local agency within 10 days of the date of the report [Section 2646.1 (d) CCR). <br />6. Quantitative and Qualitative Methods: <br />a. A leak threshold, minimum detectable leak rate, and calculated leak rate must be provided for each tank. If not, then the tank failed the SIR test. <br />b. If the calculated leak rate for a tank is greater than or equal to the leak threshold, the tank failed the SIR test. <br />c. If the minimum detectable leak rate for a tank is greater than the certified performance standard (i.e., 0.1 or 0.2 gph) and the calculated leak rate <br />is less than the leak threshold, the test is inconclusive for that month. <br />d. Two consecutive failures and/or inconclusives require a tank and/or piping integrity test within 15 days from the date of the <br />second report [Section 2646.1 (h) CCR]. <br />7.
