1. a) Whether the risk assessment procedure used is nationally recognized and accepted including, but not limited to, those procedures incorporated by reference in Section 742.210;
2. b) Whether the site-specific data reflect actual site conditions;
3. c) The adequacy of the investigation of present and post-remediation exposure routes and risks to receptors identified at the site;
4. d) The appropriateness of the sampling and analysis;
5. e) The adequacy and appropriateness of toxicity information;
6. f) The extent of contamination;
7. g) Whether the calculations were accurately performed;
8. h) Similar-acting chemicals shall be specifically addressed. At a minimum, the chemicals subject to this requirement are identified in Appendix A, Tables E and F; and

9. i) Proposals seeking to modify the target risk consistent with Section 742.900(d) shall address the following factors:

   1. 1) the presence of sensitive populations;
   2. 2) the number of receptors potentially impacted;
   3. 3) the duration of risk at the differing target levels; and
   4. 4) the characteristic of the chemicals of concern.

A comprehensive site-specific risk assessment shall demonstrate that contaminants of concern at a site do not pose a significant risk to any human receptor. All site-specific risk assessments shall be submitted to the Agency for review and approval. A submittal under this Section shall address the following factors:
