This guidance does not constitute rulemaking by the Agency, and cannot be relied on to create a substantive or procedural right enforceable by any party in litigation with the United States. EPA may take action that is at variance with the policies and procedures in this manual and may change them at any time without public notice.  \nThis interim final guidance is based on policies in the proposed revisions to the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), which were published on December 21, 1988 (53 Federal Register 51394) . The final NCP may adopt policies different than those in this manual and should, when promulgated, be considered the authoritative source. A final version of this manual will be  \npublished after the revised NCP is promulgated.    \nFollowing the date of its publication, this manual is intended to be used as guidance for all human health risk assessments conducted as part of Superfund remedial investigations and feasibility studies. Issuance of this manual does not invalidate human health risk assessments completed before (or in progress at) the publication date and based on previously released Agency guidance.  \nComment [A1]: The latest revisions to the NCP were finalized in 1994. An overview of the final NCP and a link to the full text are available at:  \n[http://www.epa.gov/oem/content/lawsregs/ncp](http://www.epa.gov/oem/content/lawsregs/ncp)[ ](http://www.epa.gov/oem/content/lawsregs/ncp)[over.htm](over.htm)  \nThis document represents an annotated version of the Risk Assessment Guidance for Superfund (RAGS) Part A. Since the original publication of this guidance in 1988, EPA has issued a number of guidance documents, directives and other policy documents that update, supplement, supersede or otherwise affect RAGSPartA, or contain new information about one or more topics that are substantially addressed in RAGSPartA. There may be additional supplemental guidance available on EPA's Superfund risk assessment website  \n(see [http://www.epa.gov/swerrims/riskassessment/risk_superfund.html](http://www.epa.gov/swerrims/riskassessment/risk_superfund.html))  \nThe underlying text of RAGSPartA remains unchanged; any typographical errors or missing text reflects the PDF original. Annotations have been added to this document as electronic `sticky notes. ' To view the information contained in a sticky note, simply place your cursor over it or click it and the text will expand. To close the note, press the escape key or click on the `X' in the upper righthand corner of the note header. In addition, the word `link' appears in parentheses near each sticky note. This text is a hyperlink that users can click to open the relevant document that serves as the source of the information provided in the note.  \nAll sections of RAGSPartA that have at least one annotation are marked in the Table of Contents with a blue arrow and highlighted in yellow.
