Sewage sludge weight means the weight of sewage sludge, in dry U.S. tons, including admixtures such as liming materials or bulking agents. Monitoring frequencies for sewage sludge parameters are based on the reported sludge weight generated in a calendar year (use the most recent calendar year data when the NPDES permit is up for renewal).
Diesel means a distillate oil which can be used as fuel for the operation of a compression ignition engine and which has an approximate boiling temperature of between 150 °C to 400 °C;
Reactor means a vat or vessel, which may be jacketed to permit temperature control, designed to contain chemical reactions.
Sewage sludge means a solid, semi-solid, or liquid residue generated during the treatment of domestic sewage in a treatment works as defined in section 6111.01 of the Revised Code. "Sewage sludge" includes, but is not limited to, scum or solids removed in primary, secondary, or advanced wastewater treatment processes. "Sewage sludge" does not include ash generated during the firing of sewage sludge in a sewage sludge incinerator, grit and screenings generated during preliminary treatment of domestic sewage in a treatment works, animal manure, residue generated during treatment of animal manure, or domestic septage.
HEPA filter means high-efficiency particulate air filters that are rated to achieve a minimum initial particle-removal efficiency of 99.97 per cent using ASTM F 1471– 93 or equivalent standard;
ESD refers to “Educational Service District”.as defined in RCW 28A.310.010.
COVID-19 symptoms means fever of 100.4 degrees Fahrenheit or higher, chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, or diarrhea, unless a licensed health care professional determines the person’s symptoms were caused by a known condition other than COVID-19.
Plasma arc incinerator means any enclosed device using a high intensity electrical discharge or arc as a source of heat followed by an afterburner using controlled flame combustion and which is not listed as an industrial furnace.
Polystyrene foam means blown polystyrene and expanded and
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than one 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.
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
Filter means material placed in the useful beam to preferentially absorb selected radiations.
Nuclear pharmacy means a pharmacy providing radio-pharmaceutical service.
Underground source of drinking water means an aquifer or its portion:
Filter profile means a graphical representation of individual filter performance, based on continuous turbidity measurements or total particle counts versus time for an entire filter run, from startup to backwash inclusively, that includes an assessment of filter performance while another filter is being backwashed.
Expanded polystyrene means blown polystyrene and expanded
Seepage pit means an excavation deeper than it is wide that receives septic tank effluent and from which the effluent seeps from a structural internal void into the surrounding soil through the bottom and openings in the side of the pit.
Engine degreaser means a cleaning product designed to remove grease, grime, oil and other contaminants from the external surfaces of engines and other mechanical parts.
Pump spray means a packaging system in which the product ingredients within the container are not under pressure and in which the product is expelled only while a pumping action is applied to a button, trigger or other actuator.
Chip means an integrated circuit embedded in the Card.
CID means a contiguous geographic area, designated by the Council for the levying of an additional rate on rateable properties within its boundaries to finance improvements and upgrades of the district to be carried out by its management body as contemplated in section 22 of the MPRA, which may be further categorised as a Residential Improvement District, Mixed-Use Improvement District or Business Improvement District;
Nuclear reactor means any apparatus designed or used to sustain nuclear fission in a self-supporting chain reaction or to contain a critical mass of fissionable material.
Dataset means the data specified in Appendix 1 (Environmental Information) to Schedule 11.2 (Management Information) as the same may be amended from time to time by the Secretary of State (acting reasonably);
Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
Sedimentation means a process for removal of solids before filtration by gravity or separation.
Radionuclide means a radioactive element or a radioactive isotope.
