In-stream Waste Concentration or "(IWC)" means the concentration of a discharge in the receiving water after mixing has occurred in the allocated zone of influence.
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.
Electrostatic application means the application to a substrate of charged atomized paint droplets that are deposited by electrostatic attraction.
Grease interceptor means an indoor device located in a food service facility or under a sink designed to collect, contain and remove food wastes and grease from the waste stream while allowing the balance of the liquid waste to discharge to the System by gravity.
Fluoroscopy means a technique for generating x-ray images and presenting them simultaneously and continuously as visible images. This term has the same meaning as the term "radioscopy" in the standards of the International Electrotechnical Commission.
Automated external defibrillator means a defibrillator device to which all of the following apply:
Interceptor means a device designed and installed so as to separate and retain deleterious, hazardous, or undesirable matter from normal wastes, while allowing normal sewage or wastes to discharge into the drainage system by gravity.
Electrostatic spray means a method of applying a spray coating in which opposite electric charges are applied to the substrate and the coating. The coating is attracted to the substrate by the electrostatic potential between them.
Dispersion technique means any technique which attempts to affect the concentration of a pollutant in the ambient air by:
thalassemia means a group of inherited disorders characterised by reduced or absent amounts of haemoglobin.
Vapor control system means a system that prevents release to the atmosphere of gasoline vapors in excess of 80 milligrams per liter of gasoline loaded (4.7 grains per liter).
Hydraulic lift tank means a tank holding hydraulic fluid for a closed-loop mechanical system that uses compressed air or hydraulic fluid to operate lifts, elevators, and other similar devices.
Radiation therapy simulation system means a radiographic or fluoroscopic x-ray system intended for localizing the volume to be exposed during radiation therapy and confirming the position and size of the therapeutic irradiation field.
Disinfection profile means a summary of Giardia lamblia inactivation through the treatment plant.
Analytical x-ray system means a group of components utilizing x-rays to determine the elemental composition or to examine the microstructure of materials.
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 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.
Emission control system means the electronic engine management controller and any emission related component in the exhaust or evaporative system which supplies an input to or receives an output from this controller.
Tomogram means the depiction of the x-ray attenuation properties of a section through the body.
Wild animal means any mammal, bird, fish, or other creature of a wild nature endowed with sensation and the power of voluntary motion.
Single tomogram system means a CT x-ray system which obtains x-ray transmission data during a scan to produce a single tomogram.
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).
Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.
Traffic control signal means a device, whether manually, electrically, or mechanically operated, by which traffic is alternately directed to stop and permitted to proceed.
Leak-detection system means a system capable of detecting the failure of either the primary or secondary containment structure or the presence of a release of hazardous waste or accumulated liquid in the secondary containment structure. Such a system must employ operational controls (e.g., daily visual inspections for releases into the secondary containment system of aboveground tanks) or consist of an interstitial monitoring device designed to detect continuously and automatically the failure of the primary or secondary containment structure or the presence of a release of hazardous waste into the secondary containment structure.
Tomographic plane means that geometric plane which is identified as corresponding to the output tomogram.
