Section 250-RICR-120-05-43.5 - DefinitionsA. Unless otherwise expressly defined in this section, the terms used in this regulation shall be defined by reference to Part 0 of this Subchapter (General Definitions). As used in this regulation, the following terms shall, where the context permits, be construed as follows: 1. "Combined heat and power" or "CHP" means a generator that sequentially produces both electric power and thermal energy from a single source.2. "Design system efficiency" means for CHP, the sum of the full load design thermal output and electric output divided by the heat input all in consistent units of measurement.3. "Distributed generator" means any generator that is not defined herein as an emergency generator.4. "Dual-fuel distributed generator" means a distributed generator that has the capacity to be fired by either a gaseous fuel (including, but not limited to, landfill methane, digester gas, or similarly produced gases) or a liquid fuel, but not by both fuels simultaneously.5. "Emergency" means an electric power outage due to a failure of the electrical grid, on-site disaster, local equipment failure, or public service emergencies such as flood, fire, or natural disaster.6. "Emergency generators" means generators used only during emergencies or for maintenance or testing purposes.7. "Generator" means any equipment that converts primary fuel (including fossil fuels and renewable fuels) into electricity or electricity and thermal energy. In addition to fuel-burning and power generating equipment this includes heat recovery, emission controls and any associated systems.8. "Installed" means the date on which a generator is first capable of generating electricity.9. "ISO" means International Organization for Standardization.10. "Landfill gas" means gas generated by the decomposition of organic waste deposited in a landfill (including municipal solid waste landfills) or derived from the evolution of organic compounds in the waste.11. "Nonroad engine" means: a. Except as discussed in § 43.5(A)(11)(b) of this Part, a nonroad engine is any internal combustion engine: (1) In or on a piece of equipment that is self-propelled or serves a dual purpose by both propelling itself and performing another function (such as garden tractors, off-highway mobile cranes and bulldozers); or(2) In or on a piece of equipment that is intended to be propelled while performing its function (such as lawnmowers and string trimmers); or(3) That, by itself or in or on a piece of equipment, is portable or transportable, meaning designed to be and capable of being carried or moved from one location to another. Indicia of transportability include, but are not limited to, wheels, skids, carrying handles, dolly, trailer, or platform.b. An internal combustion engine is not a nonroad engine if: (1) The engine is used to propel a motor vehicle or a vehicle used solely for competition, or is subject to standards promulgated under 42 U.S.C. § 7521 (CAA § 202); or(2) The engine is regulated by a federal New Source Performance Standard promulgated under 42 U.S.C. § 7411 (CAA § 111); or(3) The engine otherwise included in § 43.5(A)(11)(a) ((3)) of this Part remains or will remain at a location for more than twelve (12) consecutive months or a shorter period of time for an engine located at a seasonal source. A location is any single site at a building, structure, facility, or installation. Any engine (or engines) that replaces an engine at a location and that is intended to perform the same or similar function as the engine replaced will be included in calculating the consecutive time period. An engine located at a seasonal source is an engine that remains at a seasonal source during the full annual operating period of the seasonal source. A seasonal source is a stationary source that remains in a single location on a permanent basis (i.e., at least two (2) years) and that operates at that single location approximately three (3) months (or more) each year. This paragraph does not apply to an engine after the engine is removed from the location.12. "Other gaseous fuels" means gaseous fuels other than natural gas, including but not limited to propane, landfill gas, waste gas, and anaerobic digester gas.13. "Owner" means the owner of, or person responsible for, a generator subject to the requirements of this rule.14. "Power to heat ratio" means for a CHP unit, the design electrical output divided by the design recovered thermal output in consistent units of measurement.15. "Supplier" means a person or firm that manufactures, assembles, packages or otherwise supplies generators subject to the requirements of this rule.16. "Waste gas" means manufacturing or mining byproduct gases that are not used and are otherwise flared or incinerated. A manufacturing or mining byproduct is a material that is not one of the primary products of a particular manufacturing or mining operation, is a secondary and incidental product of the particular operation, and would not be solely and separately manufactured or mined by the particular manufacturing or mining operation. The term does not include an intermediate manufacturing or mining product which results from one of the steps in a manufacturing or mining process and is typically processed through the next step of the process within a short time.250 R.I.
