Preparedness for Response Exercise Program (PREP)

Preparedness for Response Exercise Program (PREP) Guidelines (External Link)

The National Preparedness for Response Exercise Program (PREP) was developed to establish a workable exercise program that meets the intent of section 4202(a) of the Oil Pollution Act of 1990 (OPA 90), amending section 311 (j) of the Federal Water Pollution Control Act (FWPCA), by adding subsection (6) and subsection (7) for spill response preparedness (33 United States Code (U.S.C.) § 1321 (j)).

PREP was developed to provide a mechanism for compliance with the exercise requirements, while being economically feasible for the U.S. Government and oil industry to adopt and sustain. PREP is a unified federal effort and satisfies the exercise requirements of the U.S. Coast Guard (USCG), the Environmental Protection Agency (EPA), the Pipeline and Hazardous Materials Safety Administration (PHMSA), and the Bureau of Safety and Environmental Enforcement (BSEE). Completion of the exercises described in the PREP Guidelines is one option for maintaining compliance with OPA 90-mandated federal oil pollution response exercise requirements.

In addition, according to the 2016 National Preparedness for Response Program (PREP), “Plan holders are encouraged to notify their PHMSA regional office at least one month in advance of conducting their PREP exercises.” Please send your annual PREP exercise schedule to PHMSA.OPA90@dot.gov. When possible, PHMSA will participate and provide feedback on your exercises.



Government-Initiated Unannounced Exercises (GIUE)

Government-Initiated Unannounced Exercises (GIUE) (External Link)

The purpose of Government-Initiated Unannounced Exercises (GIUEs) are to evaluate the effectiveness of an owner/operator's Oil Spill Response Plan (OSRP) without prior warning. GUIE's are conducted by the U.S. Coast Guard (USCG), Environmental Protection Agency (EPA), Bureau of Safety and Environmental Enforcement (BSEE), or state agencies on regulated vessels and facilities. Note: The Department of Transportation (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) reserves the authority to conduct and require an operator to participate in a GIUE, as referenced in PREP Guidelines Section 5.4.
