Sec. 19. (a) The owner, operator, or permittee must implement a program as specified in 329 IAC 10-15-1(14) and in accordance with 329 IAC 10-15-10 to detect and assess liquids that have leaked through the liner system into the leak detection zone.

(b) If the flow rate into the leak detection zone exceeds the action leakage rate for any sump, the owner, operator, or permittee must:

1. (1) notify the commissioner in writing of the exceedance within seven (7) days of the determination;
2. (2) obtain and analyze samples from the leak detection zone and arrange for analyses of the samples in accordance with the leak detection plan as specified in 329 IAC 10-15-10(3);

3. (3) submit a written assessment to the commissioner within fourteen (14) days of the determination that includes:

   1. (A) the magnitude of the leakage;
   2. (B) the likely source of the liquids;
   3. (C) the possible location, size, and cause of the leak; and
   4. (D) short term response measures that have been taken and that are planned;
4. (4) determine any additional short term or longer term response measures that will be taken; and

5. (5) within sixty (60) days of the notification that the action leakage rate was exceeded, submit to the commissioner:

   2. (B) an assessment of the potential for additional leakage and the potential for release of the liquids into the environment.

(c) Records of liquid quantities and liquid characteristics monitored by the leak detection program must be:

1. (1) maintained through the active life, closure, and post-closure periods; and
2. (2) made available to the commissioner upon request.
