CA Gov't Code Section 8670.30


An oil spill response organization may apply to the administrator for a rating of that OSRO’s response capabilities. The administrator shall establish rating levels for classifying OSROs pursuant to subdivision (b).


Upon receiving a completed application for rating, the administrator shall review the application and rate the OSRO based on the OSRO’s satisfactory compliance with criteria established by the administrator, which shall include, but is not limited to, all of the following elements:


The geographic region or regions of the state where the OSRO intends to operate.


Timeframes for having response resources on-scene and deployed.


The type of equipment that the OSRO will use and the location of the stored equipment.


The volume of oil that the OSRO is capable of recovering and containing.


The administrator shall not issue a rating until the applicant OSRO completes an unannounced drill. The administrator may call a drill for every distinct geographic area in which the OSRO requests a rating. The drill shall test the resources and response capabilities of the OSRO, including, but not limited to, on water containment and recovery, environmentally sensitive habitat protection, and storage. If an OSRO fails to successfully complete a drill, the administrator shall not issue the requested rating, but the administrator may rate the OSRO at a rating lesser than the rating sought with the application. If an OSRO is denied a requested rating, the OSRO may reapply for rating.


A rating issued pursuant to this section shall be valid for three years unless modified, suspended, or revoked. The administrator shall review the rating of each rated OSRO at least once every three years. The administrator shall not renew a rating unless the OSRO meets criteria established by the administrator, including, at a minimum, that the rated OSRO periodically tests and drills itself, including testing protection of environmentally sensitive sites, during the three-year period.


The administrator shall require a rated OSRO to demonstrate that the rated OSRO can deploy the response resources required to meet the applicable provisions of an oil spill contingency plan in which the OSRO is listed. These demonstrations may be achieved through inspections, announced and unannounced drills, or by any other means.


(1)Except as provided in paragraph (6), each rated OSRO shall satisfactorily complete at least one unannounced drill every three years after receiving its rating.


The administrator may modify, suspend, or revoke an OSRO’s rating if a rated OSRO fails to satisfactorily complete a drill.


The administrator may require the satisfactory completion of one unannounced drill of each rated OSRO prior to being granted a modified rating, and shall require satisfactory completion of one unannounced drill for each rated OSRO prior to being granted a renewal or prior to reinstatement of a revoked or suspended rating.


A drill for the protection of environmentally sensitive areas shall conform as close as possible to the response that would occur during a spill but sensitive sites shall not be damaged during the drill.


The response resources to be deployed by a rated OSRO within the first six hours of a spill or drill shall be dedicated response resources or be owned and controlled by a rated OSRO that are sufficient to meet the spill response planning requirements of the OSRO’s client owner or operator. This requirement does not preclude a rated OSRO from bringing in additional response resources. The administrator may, by regulation, permit a lesser requirement for dedicated or OSRO owned and controlled response resources for shoreline protection.


The administrator may determine that actual satisfactory spill response performance during the previous three years may be substituted in lieu of a drill.


The administrator shall issue a written report evaluating the performance of the OSRO after every unannounced drill called by the administrator.


The administrator shall determine whether an unannounced drill called upon an OSRO by a federal agency during the previous three years qualifies as an unannounced drill for the purposes of this subdivision.


Each rated OSRO shall provide reasonable notice to the administrator about each future drill, and the administrator, or his or her designee, may attend the drill.


The costs incurred by an OSRO to comply with this section and the regulations adopted pursuant to this section, including drills called by the administrator, shall be the responsibility of the OSRO. All local, state, and federal agency costs incurred in conjunction with participation in a drill shall be borne by each respective agency.


(1)A rating awarded pursuant to this section is personal and applies only to the OSRO that receives that rating and the rating is not transferable, assignable, or assumable. A rating does not constitute a possessory interest in real or personal property.


If there is a change in ownership or control of the OSRO, the rating of that OSRO is null and void and the OSRO shall file a new application for a rating pursuant to this section.


For purposes of this subdivision, a “change in ownership or control” includes, but is not limited to, a change in corporate status, or a transfer of ownership that changes the majority control of voting within the entity.


The administrator may charge a reasonable fee to process an application for, or renewal of, a rating.


The administrator shall adopt regulations to implement this section as appropriate. At a minimum, the regulations shall appropriately address all of the following:


Criteria for successful completion of a drill.


The amount and type of response resources that are required to be available to respond to a particular volume of spilled oil during specific timeframes within a particular region.


Regional requirements.




The process for applying for a rating, and for suspension, revocation, appeal, or other modification of a rating.


Ownership and employment of response resources.


Conditions for canceling a drill due to hazardous or other operational circumstances.


Any letter of approval issued from the administrator before January 1, 2002, that rates an OSRO shall be deemed to meet the requirements of this section for three years from the date of the letter’s issuance or until January 1, 2003, whichever date occurs later.
