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

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;

d. Include an analysis of the effectiveness of potential remedial measures in meeting all requirements of subsection 2 and include the following:

(2) Long-term management needs such as monitoring, operation, and maintenance; and

(3) Need to coordinate with and obtain necessary approvals or permits from other agencies.

c. The need for interim measures to control the sources of the release and to protect human health and environmental resources.

d. The schedules for initiating, conducting, and completing the potential remedial measure.

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.
