chemically fixed sewage sludge which is not hazardous waste, manure, vegetable of animal solid and semisolid wastes, and other discarded solid and semi solid waste.

Sound Power: Measures the loudness of a source of noise as a fixed amount of energy at the source. Sound power can be thought of as analogous to the wattage rating of a light bulb; both measure a fixed amount of energy at the source.

Sound Pressure: Sound pressure or sound level is a measurement of loudness at a fixed point not at the source of noise. Sound pressure or sound level is analogous to the level of brightness of light generated by a light bulb at a particular location; both can be measured with a meter at a specific distance from the source, and possible blockages between the source and receptor, as well as the immediate surroundings at the receptor influence the magnitude of each.

Special Status Species: Federal and state classifications for plant and animal species that are either listed as threatened or endangered, are formally recognized candidates for a listing, or are declining to a point where they may be listed.

Specific Plan: A tool authorized by California Government Code §65450 et. seq. for the systematic implementation of the General Plan for a defined portion of a community’s planning area. A specific plan must specify in detail the land uses, public and private facilities needed to support the land uses, phasing of development and use of natural resources, and a program of implementation measures, including financing measures.

Stationary Sources: Non-mobile sources such as power plants, refineries, and manufacturing facilities, which emit air pollutants.

Stormwater: Discharges generated by runoff from land and impervious areas, such as paved streets, parking lots, and building rooftops, during rainfall and snow events that often contain pollutants in quantities that could adversely affect water quality. Most stormwater discharges are considered point sources and require coverage by a National Pollutant Discharge Elimination System (NPDES) permit.

Surface Water: Water present above the substrate or soil surface.

Tide: The alternating rise and fall of the ocean and bay surface that occurs twice a day, caused by the gravitational pull of the sun and moon upon the earth and by the rotation of the earth, moon, and sun.

Topographical change: “Topographical change” refers to differences in topography, such as differences between hillside and flat valley lands, or differences in elevations that would occur as the result of site grading.

Toxic: The property of being poisonous, of causing death or severe temporary or permanent damage to an organism.
