OSPR recently notified stakeholders that they have submitted a Notice of Proposed Rulemaking to the Office of Administrative Law with the goal of "harmoniz[ing] the existing marine and inland drills and exercises requirements into one convenient section".

We strongly suggest that those who will be affected by these new regulations review our key takeaways below as well as the Initial Statement of Reasons, Notice of Proposed Rulemaking, and draft regulations to see how they may affect your business.

If you have comments you would like to submit during this Written Comment Period, you can email them to The Written Comment Period will end on March 21, 2022 - all comments must be submitted to OSPR before then.

If you have any questions about these proposed regulations or how they may affect your business, please email to review or discuss with our team.


  • The proposed regulations will divide the state up into three geographical areas by county: Northern, Central, and Southern.

  • All facilities (Inland, Marine, and Mobile) will fall into a Tier I, Tier II, or Tier III category based on location, reasonable worst-case spill volume, and spill history.

  • All facilities will be subject to "Office of Spill Prevention and Response Initiated Events" (OSPRIE) - an unannounced drill or exercise initiated by the State of California.

  • Plan holders with assets in more than one geographical region must alternate the location of exercise scenarios to test each region at least once over any consecutive three-year period.

  • Telephonic notification drills must occur quarterly in each region for plans with cross-regional assets.

  • All vessels will be classified in the Tier I category.

  • Vessels are required to conduct one in-state CalTriVEX (California Triennial Vessel Exercise) and two in-state OR out-of-state CoreVEX (Core Vessel Exercise) per any consecutive three-year period.

  • OSPR drill coordinators must be provided an opportunity to participate in the planning and design process for all drills and exercises.

  • The requirements for meeting objectives for drills and exercises have changed across the board and vary based on the tiered system. If you have questions about which tier you fall under or how objectives may change for your business, contact us.
