| #D148 | | Dredged Material | Any material excavated or dredged from the navigable waters of the United States, including material otherwise referred to as 'spoil'. | high |
| #D149 | | Maximum Daily Effluent Limitation (MDEL) | The highest allowable daily discharge of a pollutant, over a calendar day (or 24-hour period). For pollutants with limitations expressed in units of mass, the daily discharge is calculated as the total mass of the pollutant discharged over the day. For pollutants with limitations expressed in other units of measurement, the daily discharge is calculated as the arithmetic mean measurement of the pollutant over the day. | high |
| #D150 | | Not Detected (ND) | Sample results which are less than the laboratory's MDL. | high |
| #D151 | | 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 |
| #D152 | | 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. | high |

| #D158 | | Bypass | 'Bypass' means the intentional diversion of waste streams from any portion of a treatment facility. | high |
| #D159 | | Severe property damage | 'Severe property damage' means substantial physical damage to property, damage to the treatment facilities, which causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. | high |
| #D160 | | Upset | Upset means an exceptional incident in which there is unintentional and temporary noncompliance with technology based effluent limitations (TBELs) because of factors beyond the reasonable control of the Discharger. | high |
