Filtration means a process for removing particulate matter from water by passage through porous media.
Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.
Cannabis means all parts of the plant Cannabis sativa Linnaeus, Cannabis indica, or Cannabis ruderalis, whether growing or not; the seeds thereof; the resin, whether crude or purified, extracted from any part of the plant; and every compound, manufacture, salt, derivative, mixture, or preparation of the plant, its seeds, or resin. “Cannabis” also means the separated resin, whether crude or purified, obtained from cannabis. “Cannabis” does not include the mature stalks of the plant, fiber produced from the stalks, oil or cake made from the seeds of the plant, any other compound, manufacture, salt, derivative, mixture, or preparation of the mature stalks (except the resin extracted therefrom), fiber, oil, or cake, or the sterilized seed of the plant which is incapable of germination. For the purpose of this division, “cannabis” does not mean “industrial hemp” as defined by Section 11018.5 of the Health and Safety Code. Cannabis and the term “marijuana” may be used interchangeably.
Tetrahydrocannabinol means the natural or synthetic equivalents of the substances contained in the plant, or in the resinous extractives of, Cannabis sativa, or any synthetic substances, compounds, salts, or derivatives of the plant or chemicals and their isomers with similar chemical structure and pharmacological activity.
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Brachytherapy means a method of radiation therapy in which sealed sources are utilized to deliver a radiation dose at a distance of up to a few centimeters, by surface, intracavitary, or interstitial application.
Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.
Nematode means invertebrate animals of the phylum nemathelminthes, and class nematoda, i.e., unsegmented round worms with elongated, fusiform, or saclike bodies covered with cuticle, and inhabiting soil, water, plants, or plant parts, may also be called nemas or eelworms.
coronavirus means severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2);
Sorbent means a material that is used to soak up free liquids by either adsorption or absorption, or both. “Sorb” means to either adsorb or absorb, or both.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Polymer means a substance consisting of molecules characterised by the sequence of one or more types of monomer units. Such molecules must be distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units. A polymer comprises the following:
cannabis resin means the separated resin, whether crude or purified, obtained from any plant of the genus Cannabis;
Polyolefin adhesive means an aerosol adhesive designed to bond polyolefins to substrates.
Brachytherapy source means a radioactive source or a manufacturer-assembled source train or a combination of these sources that is designed to deliver a therapeutic dose within a distance of a few centimeters.
Epinephrine auto-injector means a device for immediate self-administration or administration by another trained person of a measured dose of epinephrine to a person at risk of anaphylaxis.
nanomaterial means a natural, incidental or manufactured material containing particles in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the particles in the number size distribution, one or more external dimensions is in the size range 1-100 nm;
Cannabidiol means a finished preparation containing, of its total cannabinoid content, at least 98 percent cannabidiol and not more than 0.90 percent tetrahydrocannabinol by volume that has been extracted from marijuana or synthesized in a laboratory.
Filter means material placed in the useful beam to preferentially absorb selected radiations.
Sensor means any measurement device that is not part of the vehicle itself but installed to determine parameters other than the concentration of gaseous and particle pollutants and the exhaust mass flow.
Catalyst means a substance whose presence enhances the reaction between chemical compounds.
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);
Biomethane means biogas that meets pipeline quality natural gas standards.
Biofuel means liquid or gaseous fuel for transport produced from biomass;
Cannabis concentrate means cannabis that has undergone a process to concentrate one or more active cannabinoids, thereby increasing the product’s potency. Resin from granular trichomes from a cannabis plant is a concentrate for purposes of this division. A cannabis concentrate is not considered food, as defined by Section 109935 of the Health and Safety Code, or a drug, as defined by Section 109925 of the Health and Safety Code.
Cannabis waste means waste that is not hazardous waste, as defined in Public Resources Code section 40141, that contains cannabis and that has been made unusable and unrecognizable in the manner prescribed in sections 5054 and 5055 of this division.
