High-temperature coating means a high performance coating labeled and formulated for application to substrates exposed continuously or intermittently to temperatures above 204oC (400oF).
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.
Traffic control signal means a device, whether manually, electrically, or mechanically operated, by which traffic is alternately directed to stop and permitted to proceed.
Operating pressure means the pressure at which the parts of an irrigation system are designed by the manufacturer to operate.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which (1) a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and (2) while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
PJM Control Area means the Control Area recognized by NERC as the PJM Control Area.
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).
Internal combustion engine or ‘engine’ means an energy converter, other than a gas turbine, designed to transform chemical energy (input) into mechanical energy (output) with an internal combustion process; it includes, where they have been installed, the emission control system and the communication interface (hardware and messages) between the engine's electronic control unit(s) and any other powertrain or non-road mobile machinery control unit necessary to comply with Chapters II and III;
Control system means a system for controlling the light output of a Luminaire, including:
Engineering controls means constructed containment barriers or systems that control one or more of the following: downward migration, infiltration, or seepage of surface runoff or rain; or natural leaching migration of contaminants through the subsurface over time. Examples include caps, engineered bottom barriers, immobilization processes, and vertical barriers.

Dosimetry processor means an individual or an organization that processes and evaluates individual monitoring devices in order to determine the radiation dose delivered to the monitoring devices.
Backpressure means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer's side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
Non-Synchronized Reserve Event means a request from the Office of the Interconnection to generation resources able and assigned to provide Non-Synchronized Reserve in one or more specified Reserve Zones or Reserve Sub-zones, within ten minutes to increase the energy output by the amount of assigned Non-Synchronized Reserve capability. Non-Variable Loads:
Maintenance area means any geographic region of the United States previously designated nonattainment pursuant to the CAA Amendments of 1990 and subsequently redesignated to attainment subject to the requirement to develop a maintenance plan under §175A of the CAA, as amended.
Generator Maintenance Outage means the scheduled removal from service, in whole or in part, of a generating unit in order to perform necessary repairs on specific components of the facility, if removal of the facility meets the guidelines specified in the PJM Manuals.
Continuous emission monitoring system or "CEMS" means the equipment required under section 11 of this rule to sample, analyze, measure, and provide, by means of readings recorded at least once every fifteen (15) minutes, using an automated data acquisition and handling system (DAHS), a permanent record of nitrogen oxides emissions, stack gas volumetric flow rate, stack gas moisture content, and oxygen or carbon dioxide concentration, as applicable, in a manner consistent with 40 CFR 75*. The following systems are the principal types of continuous emission monitoring systems required under section 11 of this rule:
Radiation detector means a device which in the presence of radiation provides a signal or other indication suitable for use in measuring one or more quantities of incident radiation.
