For the purpose of this chapter, the following abbreviations and definitions shall apply unless the context clearly indicates or requires a different meaning.
(a) Abbreviations.
(1) “BOD.” Biochemical oxygen demand, a measure of the strength of the sewage that includes its ability to biologically consume the dissolved oxygen.
(2) “COD.” Chemical oxygen demand, a measure of the strength of the sewage that includes its ability to chemically consume dissolved oxygen.
(3) “HW.” Hauled wastewater, typically dirty liquids delivered over-the-road, by truck.
(4) “HWDP.” Hauled wastewater discharge permit, required for all but RVs and carpet cleaners.
(5) “MIPP.” Municipal Industrial Pretreatment Program, instituted to control the levels of various substances discharged from industries into the sanitary sewer system.
(6) “pH.” Potential of hydrogen, a measure of the hydrogen ions in a liquid, the measure of acidity or alkalinity in the fluid.
(7) “POTW.” Publicly-Owned Treatment Works, means a water reclamation facility or wastewater treatment plant owned by a governmental agency such as a Village or County.
(8) “RVs.” Recreational vehicles, campers with self-contained toilets and holding tanks for dirty water.
(9) “SRF.” Septage Receiving Facility, built in 2007 in order to improve security of the VOMG wastewater treatment facilities and also to allow receipt of residential septage, carpet cleaning wastewater, porta-potty servicing waste, and certain other commercial wastewater deliveries.
(10) “TTO.” Total toxic organics, a category list of organic compounds typically analyzed by a laboratory to determine whether the subject mixture qualifies as “hazardous” as defined by USEPA. See also “Priority pollutants”.
(11) “VOMG.” Village of Mt. Gilead.
(12) “WWTP.” Wastewater Treatment Plant, a POTW owned and operated by the Village.
(b) Words and Phrases.
(1) “Biosolids.” Semi-solid liquid residue generated during the treatment of sewage in treatment works. Also known as “sludge”.
(2) “Catch basins.” Tanks used to contain storm water runoff from roadsides, parking lots, and loading dock areas. “Catch basins” are often designed with screens or baffles to catch and retain debris from these areas, and these will need to be cleaned under new storm water regulations. “Catch basins” are not to be confused with grease interceptors (traps).
(3) “Chemical toilets.” Portable toilets that often produce high-strength wastewater and may contain special odor-controlling chemicals.
(4) “Commercial septage.” For the purpose of this chapter, wastewater removed from a tank that receives commercial wastewater and does not include grease removed from a grease trap at a restaurant.
(5) “Composite sample.” A sample composed of two or more discrete grab samples. The aggregate sample will reflect the average quality covering the compositing or sample period.
(6) “Domestic septage.” For the purposes of this chapter, “domestic septage” is residential septage. “Domestic septage” does not include liquid or solid material removed from a tank that receives either commercial wastewater or industrial wastewater, and does not include grease removed from a grease trap at a restaurant.
(7) “Facility operator.” Person in day-to-day control over the operations at a plant.
(8) “Grab sample.” A sample taken (grabbed) from a flowing waste stream.
(9) “Grease and oil.” See “Oil and grease”.
(10) “Grease trap.” A tank designed to capture floating material (grease, oil, soap scum) from a wastewater stream. Restaurants, for example, must include a grease trap in their plumbing to prevent grease or oil from entering the sanitary sewer system, where such materials can clog the pipe and cause flooding.
(11) “Grease trap waste.” Floatable material such as grease, oil, or soap scum removed from a grease trap at a restaurant, school, hospital, auto-service facility, etc.
(12) “Ground water.” Water coming from below the land surface, perhaps seeping into a basement or auto-mechanic's pit.
(13) “Hauled wastewater.” Wastewater delivered “over-the-road” by truck, trailer, van, or RVs.
(14) “Holding tank.” Vessel for collecting wastewaters and emptied more frequently than once every six months.
(15) “Holding tank waste.” Materials removed from tanks serviced more often than once every six months.
(16) “Industrial septage.” For the purposes of this chapter, material removed from a tank that receives industrial processing wastewater and does not include grease removed from a grease trap at a restaurant.
(17) “Industrial wastewater.” Wastewater from an industrial source which would normally be issued Industrial Waste Discharge permits under the MIPP program.
(18) “Interference.” A discharge which inhibits or disrupts the POTW treatment processes or operations and therefore causes violations of regulatory provisions or permits.
(19) “Leachate.” Seepage from storage piles or landfills.
(20) “Oil and grease.” Floatables removed from a grease trap such as: (a) Hydrocarbon based waste from auto service facilities; (b) Oil and grease from food processing; (c) Soap scum.
(21) “Pass through.” A contaminant that passes through the POTW without being adequately reduced by the POTW processes and which is a cause of a POTW violation.
(22) “Porta-potty.” See the definition, herein, for “chemical toilet”.
(23) “Priority pollutants.” A category list of 138 different chemicals, compounds, and elements defined by USEPA as “Hazardous.” See also “TTO”.
(24) “Publicly-Owned Treatment Works (POTW).” A water reclamation facility or wastewater treatment plant owned by a governmental agency such as a state or municipality. This includes the sewers and pipes that convey wastewater to a POTW.
(25) “Residential septage.” Wastewater and solids pumped from residential home septage tanks.
(26) “Sanitary sewer system.” The collection pipes designed to deliver sanitary wastewater (toilet, tub, sink, shower, etc.) from the community to the POTW; not to be confused with “Storm sewer system”.
(27) “Septage.” For the purposes of this chapter, wastewater collected in tanks that are emptied less often than once in six months. See also the definitions herein for “Residential septage”, “Industrial septage”, “Commercial septage”, and “Holding tank waste”.
(28) “Septage Receiving Facility.” For the purposes of this chapter, the facility that receives any hauled wastewater from over-the-road vehicles.
(29) “Sludge.” Semi-solid liquid residue generated during the treatment of sewage in a treatment works. Also known as “Biosolids”.
(30) “Storm sewer system.” The collection pipes designed to deliver storm water runoff from roads, parking lots, and other land directly into the creeks and rivers; not to be confused with “Sanitary sewer system”.
