California State Lands Commission Background
Established in 1938 by passage of the State Lands Act Authority: Div. 6 or the California Public Res. Code Commission given jurisdiction over all Oil and Gas Development on Sovereign Lands
Shares responsibility of oversight of oil drilling and production with the California Division of Oil, Gas, and Geothermal Resources
Statutory authority over all Marine Terminal oil transfer operations in 1990 (Lempert‐Keene‐Seastrand)

Sovereign Lands – Coastal tide and submerged lands, and lands underlying rivers, streams, lakes, bays.Approximately 4 million acres and 1100 miles of coastline
School Lands – Onshore State owned lands for mineral and geothermal development.Approximately 1.4 million acres.

Effectiveness of Offshore Pollution Prevention Programs Oil Operations
168 million barrels of oil produced from offshore state lease platforms
Incidences are less than 12 per year Incidence average volume is less than one ounce Average volume in past 10 years is less than ½ barrel/yr Pipelines inspected and tested annually, and all meet acceptable criteria for continued service
Will introduce new requirements for BOPE certification on all drilling wells on state leases

Offshore Producing Environment in State Waters
Shallow water depth, 55’ to 211’ water depth range Shallow well depth, approximately 3,500 to 5,000 feet vertical subsea
Low pressure producing environment (generally production operations in old, pressure reduced fields)
Few offshore facilities Low volume of production – Approx 100 BOPD well production
Artificial lift requirement – very few wells capable of natural flow

Conclusions Oil production facilities is State waters are carefully monitored and maintained at a high level of integrity
Oil spill prevention and surveillance programs are effective in assuring a high level of system efficiency and safety
State programs achieve a high level of oil producing operator cooperation and an environment of increased safety awareness
State programs result in an elevated level of confidence in facility integrity and capability to operate within design limits

Conclusions Marine Terminal pollution prevention programs and regulations have resulted in greater terminal structural integrity, better trained personnel, and a declining incidence of spills
State oil producing leases are less susceptible to uncontrolled releases as experienced in the Gulf because of the considerable differences in operating environment
Track record relative to spills incidences and volumes from oil production facilities and marine terminals has been consistently low, and declining
