Does a facility need to fill out Attachment C-II in 40 CFR 112, Appendix C if the facility is subject to the SPCC regulations and not to the FRP requirements?

If the owner or operator of a facility determines that the facility is not subject to the FRP requirements, the owner or operator shall complete and maintain at the facility the certification form contained in Appendix C-II and attach the documentation to the certified form (see 40 CFR 112.20(e)). This documentation should include how the facility came to the conclusion that it was not subject to the FRP requirements. If the facility uses an alternative formula than prescribed in Appendix C to evaluate its substantial harm criteria, the owner or operator shall attach documentation to the response plan cover sheet contained in Appendix F to demonstrate the reliability and analytical soundness of the alternative formula and notify the EPA Regional Administrator in writing that an alternative formula was used.
