摘要

The manual explains the final removal credits rule and provide demonstrations, suggestions, and guidance for POTWs in the preparation of an acceptable removal credits application. The manual also presents guidance for the Approval Authority review of a removal credits application to ensure consistency in review and approval of applications, and the continued oversight of removal credits implementation after approval. The manual is divided into two major parts. Part I provides guidance to the POTW on obtaining the necessary removal data and preparing a removal credit application. Part II provides guidance for the Approval Authority for reviewing removal credit applications, including guidance for evaluating alternative methods of demonstrating consistent removal; and criteria and procedures for modification or withdrawal of a POTW's removal credits. There are four appendices to the manual. Appendix A contains a copy of the final removal credit provision and the preamble to the rule. Appendix B gives the typical detection limits for the priority pollutants. Appendix C is an example removal credit application which provides a sample format and examples of the calculations and demonstrations required in a removal credit application. Appendix D is an example NPDES permit modification language.
