The oil analysis must be performed at the same frequency specified for changing the oil. The analysis program must at a minimum analyze the following three parameters: Total Base Number, viscosity, and percent water content. The condemning limits for these parameters are as follows: Total Base Number is less than 30 percent of the Total Base Number of the oil when new; viscosity of the oil has changed by more than 20 percent from the viscosity of the oil when new; or percent water content (by volume) is greater than 0.5. If all of these condemning limits are not exceeded, the Permittee is not required to change the oil. If any of the limits are exceeded, the Permittee must change the oil within 2 business days of receiving the results of the analysis; if the engine is not in operation when the results of the analysis are received, the engine owner or operator must change the oil within 2 business days or before commencing operation, which is later. The owner or operator must keep records of the parameters that are analyzed as part of the program, the results of the analysis, and the oil changes for the engine. The analysis program must be part of the maintenance plan for the engine. [40 C.F.R. § 63.6625(i)] (h) The Permittee shall operate emergency stationary RICE according to the requirements listed in this section. In order for the engine to be considered an emergency stationary RICE under 40 C.F.R. Part 63, Subpart ZZZZ, any operation other than emergency operation, maintenance and testing, emergency demand response, and operation in non-emergency situations for 50 hours per year, as listed in this section, is prohibited. Emergency engines that do not operate according to the requirements in this section will not be considered an emergency engine under 40 C.F.R. Part 63, Subpart ZZZZ and must meet all requirements for non-emergency engines. [40 C.F.R. § 63.6640(0] (i) There is no time limit on the use of emergency stationary RICE in emergency situations.

a. Emergency stationary RICE may be operated for 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 Permittee may petition EPA for approval for additional hours to be used for maintenance checks and readiness testing, but a petition is not required if the Permittee maintains records indicating that federal, state, or local standards require maintenance and testing of emergency RICE beyond 100 hours per calendar year. [40 C.F.R. § 63.6640 (f)(2)(i)] (iii) The Permittee may operate the emergency stationary RICE for up to 50 hours per calendar year in non-emergency, situations. The 50 hours of operation in non-emergency situations are counted as part of the 100 hours per calendar year for maintenance and testing provided in 40 C.F.R. § 63.6640(f)(2)(i). The 50 hours per year fornon-emergency situations cannot be used for peak shaving or nonemergency demand response, or to generate income for a facility to an electric grid or otherwise supply power as part of a financial arrangement with another entity except as provided in 40 C.F.R. § 63.6640(f)(4)(ii). The 50 hours per year for non-emergency situations can be used to supply power as part of a financial arrangement with another entity if all of the following conditions are met [40 C.F.R. § 63.6640(f)(4)]:

a. The engine is dispatched by the local balancing authority or local transmission and distribution system operator.

b. The dispatch is intended to mitigate local transmission and/or distribution limitations so as to avert potential voltage collapse or line overloads that could lead to the interruption of power supply in a local area or region.

c. The dispatch follows reliability, emergency operation or similar protocols that follow specific NERC, regional, state, public utility commission or local standards or guidelines.

d. The power is provided only to the facility itself or to support the local transmission and distribution system.Grand Casino Hinckley
