1. 1. Within ninety days of finding that a parameter has been detected at a statistically significant level exceeding the ground water standards established under sections 33.1-20-13-02 and 33.1-20-13-03, the owner or operator shall initiate an assessment of remedial measures. An owner or operator of a CCR unit that is subject to the provisions of chapter 33.1-20-08 is exempt from the requirements of this section. The assessment must:

1. a. Be completed within a reasonable time period, unless otherwise specified by permit or the department;

2. b. Include an evaluation of the nature and extent of the release of the constituents including pathways to human and environmental receptors;

3. c. For municipal landfills, include ground water sampling and analysis for all parameters listed in appendix 1 of this chapter. The department may delete any of the appendix 1 parameters if it can be shown that the removed constituents are not reasonably expected to be in or derived from the waste within the leaking facility;

4. d. Include an analysis of the effectiveness of potential remedial measures in meeting all requirements of subsection 2 and include the following: 1. (1) The performance, reliability, ease of implementation, and potential impacts of each potential remedial measure; 2. (2) The time required to begin and complete each potential remedial measure; 3. (3) The costs of implementation of each potential remedial measure; and 4. (4) The permit requirements or other environmental or public health requirements that may substantially affect implementation of each potential remedial measure; and

5. e. When requested by the department, the owner or operator must discuss results of the assessment of remedial measures, prior to selection of a corrective action remedy, in a public meeting with interested and affected persons.

2. 2. Based on the results of the assessment of remedial measures conducted under subsection 1, the owner or operator must select a corrective action remedy within thirty days which, at minimum, meets the following standards:

1. a. Is protective of human health and environmental resources;

2. b. Attains the ground water protection standards under sections 33.1-20-13-02 and 33.1-20-13-03;

1. c. Controls the sources of release so as to reduce or eliminate, to the maximum extent practicable, further releases of constituents that may pose a threat to human health or environmental resources; and
2. d. Complies with this article and other applicable environmental statutes and rules.3. When selecting a corrective action remedy under subsection 2, the owner or operator shall consider these factors:- a. The short-term and long-term effectiveness of the potential remedial measure considering:
3. (1) Magnitude of reducing exposure to constituents;
4. (2) Likelihood of further releases;
5. (3) Practical capability of technologies; and
6. (4) Time until the standards are achieved.
7. b. The ease or difficulty of implementing the potential remedial measure considering:
8. (1) Availability of equipment and specialists;
9. (2) Long-term management needs such as monitoring, operation, and maintenance; and
10. (3) Need to coordinate with and obtain necessary approvals or permits from other agencies.
11. c. The need for interim measures to control the sources of the release and to protect human health and environmental resources.
12. d. The schedules for initiating, conducting, and completing the potential remedial measure.
13. e. Practical capability of the owner or operator.4. The owner or operator shall provide the department with a document fully describing the remedial measures assessment under subsection 1 and the selected corrective action remedy under subsections 2 and 3.5. Upon selection of the corrective action remedy under subsection 2 and with the concurrence of the department, the owner or operator shall establish and implement the remedy.- a. During implementation, the owner or operator shall monitor the effectiveness of the remedy.
14. b. Implementation shall be considered complete when all actions and standards required to complete the remedy have been satisfied and approved by the department.
15. c. Upon completion of a corrective action remedy, the owner or operator shall place in the operating record a certification that the corrective action remedy has been completed. Within fourteen days of completion of the certification, the owner or operator shall notify the department that the certification has been placed in the operating record.
