The value chain for any given chemical/process facility is a relatively complex set of activities involving the company and its fixed manufacturing sites, as well as various shippers and their transportation and storage facilities. Value chain activities for a typical chemical/process facility generally consist of multiple pathways for both inbound and outbound materials. These may comprise hundreds or even thousands of individual shipments over a year's time. Performing security vulnerability analyses (SVA) for all of these individual shipments or even pathways in the same manner would be cumbersome and probably waste SVA resources. This paper proposes a method for mapping the various incoming and outgoing material pathways for potential target materials for a fixed facility and then using those results to choose which pathways require unique SVAs, which pathways can be adequately analyzed using generic SVAs, and which pathways do not require a SVA.
The American Chemistry Council (ACC) defines the value chain of chemical/process facilities as consisting of the following activities (Reference 1.):
The transportation and distribution part of the value chain includes:
Receipt of feed materials by multiple modes of transportation, including ship, barge, rail, truck, air, and pipeline.
Distribution of products and waste materials by multiple modes of transportation, including ship/barge, rail, truck, air, and pipeline. The distribution of materials from fixed sites can include:
Transportation of products directly to a customer
Possible interim storage of products
Transfer of products between carriers
Transportation of samples to potential customers
