Current through Register 2024 Notice Reg. No. 28, July 12, 2024
In 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.
