Guidance for the inventory of perfluorooctane sulfonic acid (PFOS) and related chemicals listed under the Stockholm Convention on POPs

Scope

The objective of this document is to provide step-by-step guidance that enables Parties to establish an inventory of products and articles containing PFOS and related chemicals and industrial processes using these chemicals. The guidance includes methods for estimating the amount of such chemicals in products and articles in cases where accurate data is lacking. The inventory should provide Parties with baseline data on the presence of PFOS at the national level. Such data would serve as a basis for Parties to develop strategies/action plans for meeting their obligations under the Convention in relation to PFOS.

Main target audience

The focal point responsible for coordinating the process of updating the NIP, staff responsible for planning the inventory, and technical staff responsible for conducting the inventory of PFOS.

Latest version of the Guidance (Draft revised January 2017)

Decision SC-7/10 requested parties and others to provide comments to the Secretariat based on their experience in using the most up-to-date versions of guidance documents to assist parties in developing, reviewing and updating their national implementation plans, as listed in part A of the annex  to the present decision, on how to improve their usefulness, and requests the Secretariat, subject to the availability of resources, to update the guidance documents listed in part A of the annex, as appropriate. The Secretariat has revised the draft guidance (March 2015 version) based on the comments received. The revised January 2017 version of the draft guidance for the inventory of PFOS is given below.

Review of the Guidance

The process for review of the guidance has been initiated by decision SC-6/12 on the draft guidance for the inventory of perfluorooctane sulfonic acid (PFOS) and related chemicals. The request for information pursuant to decision SC-6/12 can be accessed here. The comments received in response on the draft guidance are available here. The draft revised guidance according to the comments received as of 31 March 2014 is available below in English only.
