Section 884.5 - Definitions and AbbreviationsIn addition to the definitions found in Government Code § 8670.3, and Chapter 1, of this subdivision, the following definitions shall govern the construction of this subchapter.
(a) "Aquatic toxicity" means that the survivorship of the test organisms in the treatment exposure is less than 90% of those in the control group. Testing to determine if an agent causes aquatic toxicity shall be done in accordance with the testing protocols in the Guidance Document.(b) "Bioremediation agent" or "bioremediant" means an OSCA which contains oil-degrading bacteria that serve a seeding function, or nutrients that serve to enhance the growth of naturally occurring bacteria. These agents are deliberately introduced into an oil discharge to increase the rate of biodegradation in an effort to mitigate the effects of the discharge.(c) "Collecting agent" means a type of OSCA, the function of which is to absorb, congeal, gel or emulsify oil. The end product of these actions is an agent-oil mass that remains afloat for later collection or burning. Collecting agents include; emulsion treating agents, herding agents, elasticity modifiers, and sorbents.(d) "Dispersing agent" or "dispersant" means a type of OSCA, the function of which is to reduce the interfacial surface tension between oil and water. Dispersing agents are surfactant-based chemical compounds, and are composed of both water and oil compatible constituents which allow oil particles to more easily enter the water column.(e) "EC50" mans Effects Concentration 50, and is the concentration at which 50% of the test organisms display an effect or response to the product being tested during the course of a specified and predetermined time period (e.g. 96 hours).(f) "Guidance Document" means the Guidance Document for the Exemption, License and Renewal of Oil Spill Cleanup Agents, dated 1/1/98, which is incorporated by reference herein. This document contains the required exemption, license and renewal forms and the instructions for their completion and use.(g) "LC50" means the median Lethal Concentration 50, and is the concentration at which 50% of the test organisms die during the course of a specified and predetermined time period (e.g. 96 hours).(h) "Mechanical control device" means any physical device or structure utilized to confine and/or remove oil from the surface of the water or the shoreline.(i) "Non-toxic" or "not toxic" means that the survivorship of the test organisms in the treatment exposure is 90% or greater than those in the control group. Testing to determine if an agent is non-toxic shall be done in accordance with the Exemption Petition section of the Guidance Document which requires a Standard LC50 bioassay on specified test species.(j) "Oil Spill Cleanup Agent" (OSCA) means a chemical, or any other substance used for removing, dispersing or otherwise cleaning up oil or any residual products of petroleum in, or on, any of the waters of the state.(k) "OSCA" means Oil Spill Cleanup Agent.(l) "Sinking agent" means a type of OSCA, the primary function of which is to combine with oil to cause sinking of the agent-oil mass. Sinking agents may not be used in the waters of California.(m) "Surface washing agent" means a type of OSCA, the function of which is to facilitate the removal of oil from shoreline substrates or other oiled surfaces. The primary effect of this type of OSCA is to act as a wetting agent to soften or lower the viscosity of the oil, thereby increasing the effectiveness of water in displacing the oil from the shoreline surfaces. A surface washing agent cannot act as a dispersant.Cal. Code Regs. Tit. 14, § 884.5
