**RULE 230**

**- ACTION ON APPLICATIONS** 

The Control Officer shall act promptly on an application for an Authority to Construct, Modify, Replace, Operate or Use, and shall notify the applicant in writing by mail or in person, of the action taken; namely approval, conditional approval, or
denial. Notice of action taken shall be deemed to have been given when the written notification has been deposited in the mail, postpaid, addressed to the address shown on the application, or when personally delivered to the applicant or his representative.

In acting upon any application for an Authority to Construct involving indirect sources or new or modified stationary sources of air contaminant s subject to the requirements of Rule 220(b), the Control Officer shall provide for public notice in accordance with the provisions of said
rule.

( **a) General Approval**

The Control Officer shall grant an Authority to Construct only after s/ he has determin ed that the new or modified stationary source of air contaminants:

(1) will cause the article, machine, equipment or other contrivance, so constructed or modified, to operate within all applicable rules and regulations pertaining to the
emission of air co ntaminants;

(2) will not prevent the attainment, interfere with the maintenance, or cause a violation, of any state or national ambient air quality standard nor interfere with the control strategy contained in the State of California Air Quality Implement ation Plan;

(3) has complied with all applicable requirements

, including the requirements of 40 CFR 52.21 provided in Rule

220 and will not cause cumulative deterioration of existing air quality in excess of the maximum allowable PSD
increments as defined in Rule 130(p 7) ;

(4) will not result in air contaminant emissions in excess of the allowable standards established by the Environmental Protection Agency for new stationary sources of the category types listed in Rule 490 and 492 of the District, or emplo ys best available control technology, BACT, for

exceeded; whichever is the more restrictive condition; and

(5) provides adequate facilities for sampling, emission monitoring, and reporting procedure s as specified by the
Control Officer.

NOTE: The variance provisions of the California Health and Safety Code do not apply to sources or emissions subject to the requirements of Rules 490 & 492.

**(b) New Source Approval**

(1) Immediately upon filing the public notice for a new or modified stationary source subject to the provisions of Rule 220, the Control Officer shall forward to the
California Air Resources Board and Environmental Protection Agency an analysis of the effect of the source on air quality and the preliminary decision to grant or deny the Authority to Construct.

(2) An Authority to Construct for any stationary source subject to the provisions of Rule 220, may not be granted or denied by the Control Officer until at least 30 days

after the d ate of public notice.

**(c) Denial of Application**

The Control Officer shall deny an Authority to Construct for any new or modified stationary source of air contaminants which does not meet the requirements specified in Rule 230. In
the event of such denia l, the Control Officer shall notify the applicant in writing of the reasons therefore. Service of this notification may be made in person or by mail, addressed to the applicant at the address set forth on the application, and such service may be proved by the written acknowledgement of the persons served or affidavit of the person making the service. The Control Officer shall not accept a further application unless the applicant has satisfied the requirements which were
the basis for denial of the Authority to Construct.

**(d) Conditional Approval**

The Control Officer may issue an Authority to Construct, subject to conditions which will assure the operation of any equipment or stationary source within the applicable standards set forth in these regu lations, in which case, the conditions

No conditional approval may be granted for any proposed stationary sourc e that would violate the general approval requirements of Rule 230(a)(2) with respect to a federal, state, or local ambient air quality standard unless all the following conditions are met for the applicable (violating) pollutant:

(1) The new source is r equired to employ "Best Available Control Technology".

(2) Emission reductions fr o m existing sources in the area of the proposed new source are required such that the total actual emissions from the combined existing and proposed
sources will be less than the total actual emissions from the existing sources prior to the date of application for the Authority to Construct. Any emission reductions of this type must be enforceable by revised permit conditions or written contract agreements. However, hydrogen sulfide reductions may not be required for geothermal power plant sources in Northern Sonoma County provided all such sources owned by the applicant are in compliance with the hydrogen sulfide emission limitations of Rule 455(b).

(3) The emission reducti ons stated above will provide a positive net air quality benefit in the affected area.

(4) The applicant certified that all existing sources owned or controlled by the owner or operator of the proposed source in the State are in compliance with all applic able rules, regulations or approved compliance schedules.

The Control Officer may issue an Authority to Construct with revised conditions upon receipt of a new application, if the applicant demonstrates that the equipment or stationary
source can operate within the standards of these regulations
under the revised conditions.

**(e) Performance Standards in Effect**

The issuance of an Authority to Construct does not relieve the permit holder of the requirement to comply with all applicable rules and regulations, including emission limitations and other performance standards , whether or not such limitations and standards are explicitly stated or referenced in the permit.
