Summary ofFigures,Tables, and Information Required inACL Demonstrations 1. Figures 2. Tables 3. Information

B-1OSWER Directive 9481.00-GC

This appendix can be used as a quick reference to determine what types of information are needed for various types of ACL demonstrations. As was discussed in earlierchapters, notall the information discussed in this document is necessary in all applications. The applicant is responsible for deciding what information is necessary for the site, though the appropriate permitting authority may provide some help in making this determination. Most notably, a simplified ACL demonstration may be based strictly on an EPA reviewed dose level (with no mechanisms of attenuation considered). In some cases, as was discussed in the first chapter, this may be the only type ofACL demonstration acceptableto EPA. However, all ACL applications are required to provide certain information. If this information is not provided or is supplied in an unacceptable form, then the ground-water protection standard will be set at background or one of the MCLs listed in the regulations (40 CFR §264.94(a)). This appendix points out what information is usually required in all demonstrations, and what additional information may be required in some cases. This appendix is only a summary; it is not comprehensive. The applicant or reviewer should refer to the main body of the guidance for a more thorough discussion ofthetypes of information needed in an ACL application.
