As used in this Chapter, the following terms have the following meanings:

A. Demand Response Program. "Demand response program" means an agreement whereby under specified circumstances a facility voluntarily curtails its demand for electricity from the grid in exchange for some type of economic incentive.

B. Emergency Generator. "Emergency generator" means a generator that meets all of the following criteria:

(1) The generator is only operated to provide electrical power during an emergency situation, except as provided in paragraphs 2 and 3 below. Examples include producing power for critical networks or equipment (including power supplied to portions of a facility) when electrical power from the local utility (or the normal power source if the facility runs on its own power production) is interrupted.

(2) The generator is operated for no more than 100 hours per calendar year for the non-emergency purposes of maintenance checks and readiness testing, provided that the tests are recommended by federal, state, or local government; the manufacturer; the vendor; the regional transmission organization or equivalent balancing authority and transmission operator; or the insurance company associated with the engine. The owner or operator may be allowed additional hours for maintenance checks and readiness testing if a petition for approval is granted by the EPA in accordance with federal requirements or the owner or operator maintains records which demonstrate that maintenance and testing beyond 100 hours per calendar year is required by federal, state, or local standards.

(3) Each generator may be used for non-emergency purposes other than maintenance checks and readiness testing described in paragraph 2 above for up to 50 hours per calendar year. These operating hours will be accounted as part of the 100 hours per calendar year non-emergency operating allowance in paragraph 2 above. Those uses expressly prohibited in this rule are not permitted as part of this 50-hour allowance.

C. Generator. "Generator" means a combination of a reciprocating internal combustion engine and a device that converts the mechanical energy produced by the engine into electricity.

D. Installed. "Installed" means a generator that has been placed, secured, and connected at the location where it is intended to be operated.

E. Non-Emergency Generator. "Non-emergency generator" means any generator that does not meet the definition of emergency generator in this Chapter.

F. Nonroad Engine. "Nonroad engine" has the same meaning as defined in 40 C.F.R. § 1068.30 as amended on October 25, 2016.

G. Peak Shaving. "Peak shaving" means the use of on-site power generation to reduce power consumption from the grid.

H. Stationary Engine. "Stationary engine" means an engine that is not used in a motor vehicle and is not a nonroad engine.
