ORDER APPROVING
a Petition to Reduce PM10 Emission Rates



Elk Hills Power, LLC, the owner and operator of the Elk Hills Power Project, filed a petition on January 27, 2004, with the California Energy Commission (Commission) to reduce the PM10 emission rates based on the results of initial source tests and operating data from similar combined-cycle power plants. The reduction in emission rates will allow the project owner to conserve the quantity of emission reduction credits surrendered to the San Joaquin Valley Air Pollution Control District (District). This modification was approved by the District, and a revised Permit to Operate was issued on November 25, 2003.

The Commission approves the Elk Hills Power, LLC, petition and the revised air quality conditions of certification in accordance with Title 20, Section 1769 (a) (3) of the California Code of Regulations.

COMMISSION FINDINGS

Based on staff's analysis, the Commission concludes that the proposed changes will not result in any significant impact to public health and safety, or the environment. The Commission finds that:

  • There will be no new or additional significant environmental impacts associated with the proposed changes.

  • The project will remain in compliance with all applicable laws, ordinances, regulations and standards, subject to the provisions of the Public Resources Code section 25525.

  • This amendment will be beneficial to the project owner by allowing for conservation of emission reduction credits.

  • There has been a substantial change since the Energy Commission certification based on the project owner's re-evaluation of operational information that was not available during the siting process.

CONCLUSION AND ORDER

The California Energy Commission hereby adopts the following changes to the Elk Hills Power Project Decision. New text is underlined. Deleted text is shown in strikeout.

AQ-15 Emission rates from each CTG, except during startup or shutdown, shall not exceed any of the following emission limits:

  • PM10 16.2 15.0 lbs/hr

  • SO2 3.6 lbs/hr

  • NO2 15.8 lbs/hr and 2.5 ppmvd @ 15% O2 averaged over 1-hr

  • VOC 4.0 lbs/hr and 2.0 ppmvd @ 15% O2 averaged over 3-hr

  • CO 12.5 lbs/hr and 4 ppmvd @ 15% O2 averaged over 3-hr

  • Ammonia 10 ppmvd @ 15% O2 averaged over 24-hr
    [District Rule 2201, 4001 and 4703]

Verification: The project owner shall provide records of compliance as part of the quarterly reports of Condition AQ-35.

AQ-16 Emission rates from each CTG shall not exceed any of the following:

  • PM10 388.8 360.0 lbs/day

  • SO2 86.4 lbs/day

  • NO2 752.0 lbs/day

  • VOC 184.0 lbs/day

  • CO 3948.0 lbs/day
    [District Rule 2201]

Verification: The project owner shall provide records of compliance as part of the quarterly reports of Condition .

AQ-17 Emission rates from both CTGs (S-3523-1 and -2) shall not exceed any of the following:

  • PM10 777.6 720.0 lb/day

  • SO2 172.8 lb/day

  • NO2 1103.0 lb/day

  • VOC 269.0 lb/day

  • CO 4297.0 lb/day.
    [District Rule 2201]

Verification: The project owner shall provide records of compliance as part of the quarterly reports of Condition AQ-35.

AQ-18 Annual emissions from both CTGs calculated on a twelve (12) consecutive month rolling basis shall not exceed any of the following: PM10 -283,824 262,800 lb/year, SOx (as SO2) - 57,468 lb/year, NOx (as NO2) - 335,022 lb/year, VOC - 64,478 lb/year, and CO - 831,008 lb/year. [District Rule 2201]

Verification: The project owner shall provide records of compliance as part of the quarterly reports of Condition AQ-35.

AQ-21 Prior to commencement of operation of S-3523-1-0, -2-0, & 3-0, emission offsets shall be tendered for all calendar quarters in the following amounts, at the offset ratio specified in Rule 2201 (6/15/95 version) Table 1, PM10 - Q1: 70,820 lb, Q2: 71,608 lb, Q3: 72,394 lb, and Q4: 72,394 lb; SOx (as SO2) - Q1: 14,170 lb, Q2: 14,328 lb , Q3: 14,485 lb, and Q4: 14,485 lb; NOx (as NO2) - Q1: 65,353 lb, Q2: 66,079 lb, Q3: 66,805 lb, and Q4: 66,805 lb; and VOC - Q1: 10,967 lb, Q2: 11,089 lb, Q3: 11,211 lb, and Q4: 11,211 lb. [District Rule 2201]

Additional NOx emission offsets have been tendered for the following quantities of emission, at the applicable offset ratio specified in Table 4-2 of District Rule 201 (as amended 12/19/02): NOx (as NO2) - Q1: 12,324 lbs, Q2: 12,461 lbs, Q3: 12,598lbs, Q4: 12,598 lbs. [District Rule 2201]

The requirements of this condition have been meet by the surrendering of the following emission reduction credits: certificates S-1591-1 (VOC), S-1541-5 (SO2) and S-1588-2 (NO2) and the tendering of certificate S-1583-2 (NO2 for PM10).

For the purpose of offsetting the project emission impacts and compliance with District Rule 2201, emission reduction credits are used in the following amounts.
