border to Placer County.

C.11 **S tationary Internal Combustion Engine**  **:** Any spark or compression ignited internal combustion engine that is operated, or intended to be operated, at a specific site for more than twelve (12) consecutive months, is attached
to a foundation at that s ite, or is determined to be stationary by the District.

D.2 **INITIAL COMPLIANCE DEMONSTRATION:** Each engine subject to
meet the emission limits of D.1 shall demonstrate initial compliance. Initial compliance can be achieved by:

a. Conducting a source test on the engine ; or b. Providing the District with support documentation which demonstrates that the engin e is in compliance wi th the
emission limits of this r ule.

D.3 **INITIAL COMPLIANCE TIMELINE** : Each engine shall demonstrate
i nitial compliance no later than n inety (90) days after the date of initial startup

.

D.4 **ON**

**- GOING COMPLIANCE PROGRAM**  : Upon successful demonstration of initial compliance, the owner or operator shall

demonstrate on

- going compliance as followed:

a. Each engine shall be source tested at least once every five (5) years, measured from the date of the last source test showing compliance. If init ial compliance was satisfied without any source test data, the engine 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 e mission analyzer to take NOx, CO, and O 2 readings from the engine 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 les s 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 as long as the problem is corrected and a follow

- up emission reading is conducted within 15 days of th e initial emission reading. If the problem cannot be corrected, the operator shall shutdown the engine and notify the District.

D.5 **COMPLIANCE INSPECTION** : For compliance demonstration purposes, the testing of emissions shall be conducted in

.
e. NOx emission limitations shall be expressed as nitrogen dioxide (NO 2 ).
f. VOC emission limitations shall be referenced to methane

. g. All ppmv emission limitations shall be referenced at 15% volume stack gas oxygen on a dry basis.

h. All emission readings shall be taken with the engine operating either at conditions representative of normal operations or conditions specified in the Permit to

**F. RECORDKEEPING AND REPORTING REQUIREMENTS** 

F.1 **RECORDKEEPING REQUIREMENTS:** A record of the following information shall be maintained for five years and shall be
made available to District personnel upon request:

a. The monthly and annual hours of operation or quantity of

- going emission test results to verify compliance ; and

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

F.2 **SOURCE TEST PROTOCOL AND REPORT:** A source test protocol shall be submitted to the District for review and approval at least thirty (30) days prior to any source test. The
results from the source test shall be submitted to the
