(1)Immediate Corrective Actions Needed. An analysis of the time frame, potential effectiveness, performance, risks and costs of the corrective actions immediately available or necessary to prevent significant threats to the environment or public health, and a schedule for implementation of those actions.

(2)Analysis of Long-Term Corrective Actions. A detailed evaluation must be completed of potential long-term corrective action(s) necessary to achieve compliance with all ground water and surface water requirements and standards to protect human health and the environment, and to control sources of releases so as to reduce or eliminate, to the maximum extent practicable, releases of Appendix 405.A, Column 3 constituents that may pose a threat to human health or the environment. The evaluation must, at a minimum, address the following:

(a)The performance, reliability, ease of implementation and potential impacts of each potential remedy identified, based on:

(i)the magnitude of existing and residual risks in terms of the likelihood of further releases due to waste remaining following implementation of a remedy;

(ii)the type and degree of long-term operation and maintenance required;

(iii)short-term and long-term health, safety, and environmental risks that each potential corrective action could pose to people and the environment; and

(iv)long-term reliability of the engineering and institutional control.

(b)The time required to begin and complete each potential remedy and when full protection would be achieved.

(c)The projected costs associated with the implementation of each potential remedy.

(d)Any federal, state or local licenses or permits required to be obtained prior to the implementation of each potential remedy.

NOTE: The potential long-term corrective actions for a solid waste facility are site-specific and will vary significantly depending on the design and age of the solid waste facility, the completeness of the facility's historical records, the nature and extent of contaminants found in the ground or surface water, the complexity of the site hydrogeology, and the facility's proximity to sensitive receptors or other natural resources.

(3)Selection of Corrective Actions. The facility owner and/or operator, as part of the corrective action plan, shall submit to the Department a written proposal for corrective action(s) to be taken at the facility. This proposal must detail:

(a)A correction action program, and the basis for the selection of that program, including a basis for measuring and documenting the effectiveness of the proposed program. This report must include:

(i)the extent to which different corrective actions would reduce further releases, and

(ii)the ease or difficulty of implementing proposed remedies. This analysis must include the following factors: constructing the technology, operational reliability and availability of
