Occurs during, or as a result of, the treatment or disposal of wastes. | high | |
| #D051 | Pollution Prevention | Pollution Prevention means any action that causes a net reduction in the use or generation of a hazardous substance or other pollutant that is discharged into water and includes, but is not limited to, input change, operational improvement, production process change, and product reformulation (as defined in Water Code section 13263.3). | high | |

| #D054 | Storm Water | Storm water runoff, snowmelt runoff, and storm water surface runoff and drainage. | high | |
| #D055 | Single Operational Upset (SOU) | A SOU is broadly defined as a single unusual event that temporarily disrupts the usually satisfactory operation of a system in such a way that it results in violation of multiple pollutant parameters. | high | |
| #D056 | Conventional Pollutants | Pollutants typical of municipal sewage, and for which municipal secondary treatment plants are typically designed; defined at 40 CFR section 401.16 as BOD, TSS, fecal coliform bacteria, oil and grease, and pH. | high | |
| #D057 | TCDD equivalents | TCDD equivalents represent the sum of concentrations of chlorinated dibenzodioxins (2,3,7,8- CDDs) and chlorinated dibenzofurans (2,3,7,8-CDFs) multiplied by their respective toxicity factors | high | |
| #D058 | Trash | Trash means all improperly discarded solid material from any production, manufacturing, or processing operation including, but not limited to, products, product packaging, or containers constructed of plastic, steel, aluminum, glass, paper, or other synthetic or natural materials. | high | |
| #D059 | Whole Effluent Toxicity (WET) | The aggregate toxic effect of an effluent measured directly by a chronic or acute toxicity test | high | |
| #D060 | Test of Significant Toxicity (TST) | Test of Significant Toxicity (TST) is a statistical approach used to analyze toxicity test data. The TST incorporates a restated null hypothesis, Welch's t-test, and biological effect thresholds for chronic and acute toxicity. | high | |
| #D061 | Toxicity Identification Evaluation (TIE) | A set of procedures to identify the specific chemical(s) responsible for toxicity. These procedures are performed in three phases (characterization, identification, and confirmation) using aquatic organism toxicity tests. | high | |
| #D062 | Toxicity Reduction Evaluation (TRE) | TRE is a study conducted in a step-wise process designed to identify the causative agents of effluent or ambient toxicity, isolate the sources of toxicity, evaluate the effectiveness of toxicity control options, and then confirm the reduction in toxicity. The first steps of the TRE consist of the collection of data relevant to the toxicity, including additional toxicity testing, and an evaluation of facility operations and maintenance practices, and best management practices. A TIE may be required as part of the TRE, if appropriate. | high | |
| #D063 | Water Quality Standards | Provisions of State or federal law which consist of a designated use or uses for waters of the United States and water quality criteria for such waters based upon such uses. Under State law, the Water Boards establish beneficial uses and water quality objectives in their water quality control plans or basin plans. Together with an antidegradation policy, these beneficial uses and water quality objectives serve as water quality standards under the Clean Water Act. In Clean Water Act parlance, state beneficial uses are called 'designated uses' and state water quality objectives are called 'criteria.' Throughout this General Order, the relevant term is used depending on the statutory scheme | high | |
| #D064 | Water Quality Control Plan | There are two types of water quality control plans - Basin Plans and Statewide Plans. Regional Boards adopt Basin Plans for each region based upon surface water hydrologic basin boundaries. The Regional Basin Plans designates or describes (1) existing and potential beneficial uses of ground and surface water; (2) water quality objectives to protect the beneficial uses; (3) implementation programs to achieve these objectives; and (4) surveillance and monitoring activities to evaluate the effectiveness of the water quality control plan. The Statewide Plans address water quality concerns for surface waters that overlap Regional Board boundaries, are statewide in scope, or are otherwise considered significant and contain the same four elements. Statewide Water Quality Control Plans include the Ocean Plan, the Enclosed Bays and Estuaries Plan, the Inland Surface Waters Plan, and the Thermal Plan. A water quality control plan consists of a designation or establishment for the waters within a specified area of (1) beneficial uses to be protected, (2) water quality objectives, and (3) a program of implementation needed for achieving water quality objectives [Water Code section 13050(j)]. | high | |
| #D065 | Qualifying Storm Events (QSEs) | A qualifying storm event occurs when sufficient precipitation generates runoff from the Facility that is discharged into the receiving water and is preceded by at least 48 hours with no discharge from any drainage area. | high | |
