Rhode Island Code of Regulations › Title 250 - Department of Environmental Management › Chapter 120 - Air Resources › Subchapter 05 - Air Pollution Control › Part 43 - Air Pollution Control Regulation No. 43- General Permits for Smaller-Scale Electric Generation Facilities › Section 250-RICR-120-05-43.5 - Definitions

Current through June 14, 2024
A. 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.
