Rule Title(s): Stationary Gas Turbines

Date Submitted to ARB: 

If an Amended Rule, Date Last Amended (or Adopted): 7/13/1994

Is the Rule Intended to be Sent to the U.S. EPA as a SIP Revision? Yes No (If No, do not complete remainder of form)

Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

The rule is being amended to provide a startup/shutdown exemption that will be needed to accommodate a future 

combined-cycle gas turbine power plant. Such a facility was proposed in 2008 and, while that specified proposal 

has been cancelled, the project proponent maintains that the location is still an excellent site for such a facility. In 

addition, we are conducting some administrative cleanup of the rule, removing past-due compliance dates and 

outdated definitions and efficiency factors.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

planning.

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split

Approximate Total Number of Small (<100 TPY) Sources Affected by this Amendment: 1

Percent in Nonattainment Area: 100%

Number of Large (> 100 TPY) Sources Controlled: 0 Percent in Nonattainment Area: %

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as 

necessary): 

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Continuous? Yes No

If Yes, Those Limits are in Section(s) 301 of the Rule.

Other Methods in the Rule for Achieving Emission Reductions are: The rule includes a ceiling on emissions during the 

startup period, along with emission limits that apply during various short-term excursions. The rule also requires that 

emission control equipment be operated throughout the startup period or (for selective catalytic reduction systems) as 

soon as they reach operating temperature.

V. OTHER REQUIREMENTS

The Rule Contains:

Emission Limits in Section(s): 301 Work Practice Standards in Section(s): 

Recordkeeping Requirements in Section(s): 502 Reporting Requirements in Section(s): 501

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment

Discussion: The District does not expect any emission reductions to result from this rule amendment. The limits on 

startup emissions are intended to place a ceiling on emissions in response to EPA input.
