In August 2013, EPA revised the SPCC Guidance for Regional Inspectors which is intended to assist regional inspectors in reviewing a facility’s implementation of the Spill Prevention, Control, and Countermeasure (SPCC) rule at 40 CFR part 112. This guidance document is also available to owners and operators of facilities that may be subject to the requirements of the SPCC rule, and the general public on how EPA intends the SPCC rule to be implemented. The document is designed to provide a consistent national policy on several SPCC-related issues. In accordance with the Oil Pollution Prevention regulation at 40 CFR part 112, the U.S. Environmental Protection Agency (EPA) requires certain facilities to prepare, amend, and implement Spill Prevention, Control, and Countermeasure (SPCC) Plans. The regulation is largely performance-based, which allows flexibility in meeting the rule requirements to prevent discharges of oil to navigable waters or adjoining shorelines. The SPCC rule was promulgated in 1973, with significant amendments published in 2002. EPA finalized additional revisions in 2006, 2008, 2009, and 2011. EPA developed this guidance to assist regional inspectors in implementing the SPCC program and in understanding its applicability, and to help clarify the role of the inspector in reviewing a facility’s implementation of performance-based flexibility provisions, such as environmental equivalence and impracticability. This document provides guidance to EPA inspectors, to owners and operators of facilities that may be subject to the requirements of the Spill Prevention, Control, and Countermeasure (SPCC) rule (40 CFR Part 112) and to the general public on how EPA intends the SPCC rule to be implemented. The guidance is designed to facilitate nationally-consistent implementation of the SPCC rule. The guidance is available at http://www.epa.gov/osweroe1/content/spcc/spcc_guidance.htm
