operations while combusting sub

- bituminous coal for the corresp onding date.

(3) The moisture, ash and sulfur content of the coal, as required in A.4.b.3 of this section. The average heat content of the

sub

- bituminous coal in Btu/ton, and the fuel oil in Btu/lb

- mass (during boiler start

- up), combusted for the corresp onding

date. The heat content of the sub

- bituminous coal will be based on the gross calorific value determined in A.4.b.(4) of

this section. The heat content of the fuel oil will be based on the gross calorific value determined in A.4.b.(17) of this

manufacturer. Permittee must also meet the requirements of 40 CFR parts 89, 94 and/or 1068, as they apply.

(ii) Permittee must demonstrate compliance according to one of the methods specified in 40 CFR Part 60.4211(b)(1)

thro ugh (5).

(iii) Emergency stationary ICE may be operated for the purpose of maintenance checks and readiness testing, provided

that the tests are recommended by Federal, State, or local government, the manufacturer, the vendor, or the

insurance company asso ciated with the engine. Maintenance checks and readiness testing of such units is limited to

100 hours per year. There is no time limit on the use of emergency stationary ICE in emergency situations. Anyone

may petition the Administrator for approval of ad ditional hours to be used for maintenance checks and readiness

testing, but a petition is not required if the owner or operator maintains records indicating that Federal, State, or

local standards require maintenance and testing of emergency ICE beyond 100 hours per year. For owners and

operators of emergency engines meeting standards under 40 CFR Part 60.4205, any operation other than emergency

operation, and maintenance and testing as permitted in this section, is prohibited.

(iv) If the stationary CI int ernal combustion engine is an emergency stationary internal combustion engine, the owner or

operator is not required to submit an initial notification. Starting with the model years in table 5 of 40 CFR Part 60,

Subpart IIII, if the emergency engine does n ot meet the standards applicable to non

- emergency engines in the

applicable model year, the owner or operator must keep records of the operation of the engine in emergency and

non

- emergency service that are recorded through the non

- resettable hour meter. T he owner must record the time of

operation of the engine and the reason the engine was in operation during that time.

except that owners and operators may operate the emergency engine for a maximum of 15 hours per year as part of

a demand response program if the regional transmission organization or equi valent balancing authority and

transmission operator has determined there are emergency conditions that could lead to a potential electrical

blackout, such as unusually low frequency, equipment overload, capacity or energy deficiency, or unacceptable

volta ge level. The engine may not be operated for more than 30 minutes prior to the time when the emergency

condition is expected to occur, and the engine operation must be terminated immediately after the facility is notified

that the emergency condition is no longer imminent. The 15 hours per year of demand response operation are

counted as part of the 50 hours of operation per year provided for non
