B. Each affected unit located in a nonattainment area shall not operate more than 500 hours per year, calculated monthly as the sum of each consecutive 12-month period.

1. Compliance for the consecutive 12-month period shall be demonstrated monthly by adding the total for the most recently completed calendar month to the individual monthly totals for the preceding 11 months.

2. Total emissions for any consecutive 12-month period, calculated as the sum of all emissions from operations under this condition, shall not exceed the limits stated in 9VAC5-540-180 F.

C. The approved fuels for each CI affected unit are diesel fuel, biodiesel fuel, and biodiesel blends. These fuels shall meet the following specifications:

1. Diesel fuel that meets the ASTM D975-10b specification for S15 fuel oil; maximum sulfur content per shipment, 0.0015%.

2. Biodiesel fuel which meets ASTM specification D6751-09; maximum sulfur content per shipment, 0.0015%.

D. The approved fuels for each SI affected unit are natural gas and liquid petroleum gas (LPG). These fuels shall meet the following specifications.

2. LPG, including butane and propane, that meets ASTM D1835-05, or an equivalent method approved by the department.

E. For affected units using diesel fuel or biodiesel fuel, the owner shall obtain a certification from the fuel supplier with each shipment of diesel fuel or biodiesel fuel. Each fuel supplier certification shall include the following:

1. The name of the fuel supplier.

2. The date on which the diesel fuel or biodiesel was received.

3. The quantity of diesel fuel or biodiesel delivered in the shipment.

4. A statement that the diesel fuel complies with the American Society for Testing and Materials specifications (ASTM D975-10b) for S15 fuel oil.

Records shall include the following: (i) date, (ii) time, (iii) duration, (iv) description (affected unit, pollutant affected, cause), (v) corrective action, (vi) preventive measures taken, and (vii) name of person generating the record.

C. The content and format of such records shall be arranged with the regional office. These records shall include, but are not limited to:

1. Total annual hours of operation for each affected unit, calculated monthly as the sum of each consecutive 12-month period. Compliance for the consecutive 12-month period shall be demonstrated monthly by adding the total for the most recently completed calendar month to the individual monthly totals for the preceding 11 months.

2. Records when each affected unit is used for an ISO-declared emergency including, but not limited to, the date, cause of the emergency, the ISO-declared emergency notification, and the hours of operation.

3. Records when each affected unit is used for an emergency that is not an ISO-declared emergency including, but not limited to, the date, cause of the emergency, and the hours of operation.

4. All fuel supplier certifications.

5. Engine information including make, model, serial number, model year, maximum engine power, and engine displacement for each affected unit.
