D. 2 Alternative Option : In lieu of complying with the requirements of D.1, the owner/operator may choose to permanently remove an existing engine from service and electrify the source. To satisfy this requirement, the owner/operator will:

a. Submit a statement to the Air Pollution Control Officer identifying the engine to be removed no lat er than six (6) months after District adoption of this rule, and;

b. Have the engine removed and electrify the source no later than three (3) years after District adoption of
this rule.

E. ADMINISTRATIVE REQUIREMENTS

E.1 No later than one (1) year after District adopt ion of this Rule, the owner or operator of one or more stationary internal combustion engines subject to m eet
the emission limits of D.1 shall submit an Authorit y to Construct Application.

F. COMPLIANCE DETERMINATION

F.1 Initial Compliance Demonstration : All engines subject to
meet the emission limits of D.1 shall demonstrate initial compliance. Initial compliance can be achie ved by:

a. Conducting a source test on a unit, or;

b. Providing the District with support documentation which demonstrates that the engine is in compliance
with the emission limits of this Rule.Feather River Air Quality Management District Rule 3.22 (06/01/2009)

F.2 Initial Compliance Timeline : Initial compliance shall be

demonstrated no later than:

a. Two years after District adoption of this Rule for all existing engines, or;

F.3 On-going Compliance Program : Upon successful demonstration of initial compliance, the owner or operator shall demonstrate on-going compliance as

followed:

a. All units shall be source tested at least once ever y five (5) years, measured from the date of the last source test showing compliance. If initial complian ce was satisfied without any source test data, the uni t shall be source tested no later than five (5) years after the date of initial startup.

b. During any calendar year in which a source test is not performed, the owner/operator shall use an emission analyzer to take NOx, CO, and O2 readings to verify compliance with the applicable emission
limits.

1) The analyzer shall be calibrated, maintained, and operated in accordance with the manufacturer’s specifications and recommendations. 2) Analyzer test data point intervals shall be no greater than five (5) minutes and data points shall be averaged over no less than fifteen (15) minutes of engine operation. 3) An analyzer reading in excess of the limits specified in Section D.1 shall not be considered a violation so long as the problem is corrected and a follow-up emission reading is conducted within 15 days of the initial emission reading. If the problem cannot be corrected, the operator shall shutdown the engine and notify the District.

g. The APCO may authorize the use of specific portable analyzers for the measurement of oxides of nitrogen
, carbon monoxide, and oxygen which do not meet the requirements of the test methods specified in this section provided that evidence accompanies each tes t report that instrument operation conformed to
manufacturer’s recommendations and that the instrument(s) used responded appropriately to calibration gases both before and after testing, an d provided that measurements made by the methods specified in this section shall be recognized as mo re reliable in any dispute involving measurements made by different methods. Evidence of instrument response stability shall be provided if calibration checks a re not performed at the test site immediately before a nd after testing.

H. RECORDKEEPING AND REPORTING REQUIREMENTS

, initial and on-going emission test results to verif y compliance, and;

c. Date(s) and type of maintenance performed.

H.2 A source test protocol shall be submitted to th e District for review and approval at least thirty (3 0) days prior to the source test. The results from the
