VENTURA COUNTY AIR POLLUTION CONTROL DISTRICT

Rule 26-2. New Source Review - Requirements

(Adopted 10/22/91, Revised 2/13/96)

A. Best Available Control Technology

  1. The Air Pollution Control Officer (APCO) shall deny an applicant an Authority to Construct for any new, replacement, modified, or relocated emissions unit which would have a potential to emit any of the pollutants specified in Table A-1, unless the emissions unit is equipped with the current Best Available Control Technology for such pollutants.

Table A-1.

  1. The APCO shall deny an applicant an Authority to Construct for any new, replacement, modified, or relocated emissions unit with an emission increase of any of the pollutants specified in Table A-2 and where the potential to emit for all the new, replacement, modified, and relocated emissions units at the stationary source, which are covered by the application for such Authority to Construct, would be greater than or equal to the limits specified in Table A-2, unless the emissions unit is equipped with the current Best Available Control Technology for such pollutants.

Table A-2.

Carbon Monoxide 30.0 ton/yr
Lead 0.6 ton/yr
Asbestos 0.007 ton/yr
Beryllium 0.0004 ton/yr
Mercury 0.1 ton/yr
Vinyl Chloride 1.0 ton/yr
Fluorides 3.0 ton/yr
Sulfuric Acid Mist 7.0 ton/yr
Hydrogen Sulfide 10.0 ton/yr
Total Reduced Sulfur 10.0 ton/yr
Reduced Sulfur Compounds 10.0 ton/yr

.

B. Offsets

  1. The APCO shall deny an applicant an Authority to Construct for any new, replacement, modified or relocated emissions unit with an emission increase of any of the pollutants specified in Table B-1, and where the potential to emit of the stationary source would be greater than or equal to the limits specified in Table B-1, unless offsets are provided for any emission increases of such pollutants from the new, replaced, modified, or relocated emissions unit.

Table B-1.

ROC 5.0 ton/yr
NOx 5.0 ton/yr
PM10 15.0 ton/yr
SOx 15.0 ton/yr


  1. An applicant required to provide offsets shall use emission reduction credits to provide offsets. The use of emission reduction credits to offset an emission increase shall be restricted to only those emission reduction credits which are not subject to reduction pursuant to Rules 26.4.D.1 and 26.4.D.2 during the reasonably expected duration of such emission increase.

  2. a. For any stationary source where the potential to emit would be equal to or greater than the limits specified in Table B-2, offsets for ROC and NOx shall be provided at the tradeoff ratio specified in Appendix A, multiplied by a factor of 1.1.

    b. For any stationary source where the potential to emit would be less than the limits specified in Table B-2, offsets for ROC and NOx shall be provided at the tradeoff ratio specified in Appendix A.

    c. Offsets for PM10 and SOx shall be provided at the tradeoff ratio specified in Appendix A, multiplied by a factor of 1.1.

Table B-2.

ROC 25.0 ton/yr
NOx 25.0 ton/yr


  1. An applicant for an essential public service who is required to provide offsets may use community emission reduction credits from the essential public service account of the community bank to provide offsets for ROC and NOx if the following provisions are satisfied:

  2. a. The applicant is proposing to provide some or all of the required offsets by using any emission reduction credits held by the applicant.

    b. The potential to emit of the stationary source will not exceed the limits specified in Table B-2.

    If no credits are available from the essential public service account of the community bank, the applicant shall provide offsets using emission reduction credits. All ROC and NOx emission reduction credits and community emission reduction credits provided as offsets pursuant to this section shall be provided at a tradeoff ratio of 1.0.

  3. For any applicant who is using emission reduction credits to provide offsets, the quarterly profile of the emission reduction credits and the quarterly profile of the emission increase for which the applicant is proposing to utilize the emission reduction credits as offsets shall satisfy the profile check for offsets as calculated pursuant to Rule 26.6.F.

C. Protection of Ambient Air Quality Standards

The APCO shall deny an applicant an Authority to Construct for any new, replacement, modified or relocated emissions unit which would cause the violation of any ambient air quality standard. In making this determination the APCO shall take into account any offsets which were provided for the purpose of mitigating the emission increase.

D. Certification of Statewide Compliance

The APCO shall deny an application for an Authority to Construct for any new, replacement, modified or relocated emissions unit that is located at any stationary source where the sum of all emission increases that occurred during the specified evaluation period would be greater than or equal to any of the limits specified in Table D--1, unless the applicant certifies that all major sources, as defined in their specific nonattainment area, which are located in California and which are owned or operated by the applicant, or by any entity controlling, controlled by or under common control with such applicant, are in compliance or on a schedule for compliance with all applicable emission limitations and standards.

The provisions of this Section shall only apply to a stationary source where any new, replacement, modified, or relocated emissions unit would result in an emission increase of any of the pollutants listed in Table D-1.

For the purpose of this Section the sum of all emission increases shall be equal to the emission increases for all the new, replacement, modified, and relocated emissions units at the stationary source, which are covered by the application for an Authority to Construct, plus all other emission increases at the stationary source that occurred during the evaluation period. For the purpose of this Section the evaluation period shall be a period of five consecutive calendar years consisting of the calendar year in which such application for an Authority to Construct is submitted to the District and the four calendar years immediately prior to the calendar year in which such application for an Authority to Construct is submitted to the District. Emission increases for which an Authority to Construct was issued shall be deemed to have occurred in the calendar year in which such Authority to Construct was issued. Emission increases for which an Authority to Construct was not issued shall be deemed to have occurred in the calendar year in which the physical change or change in method of operation occurred.

Table D-1

NOx 25.0 ton/yr
ROC 25.0 ton/yr


Appendix A

With the exception of the north zone of the District and the outer continental shelf, all locations presented in Appendix A are based on the growth and non-growth areas of Ventura County. The growth and non-growth areas were developed by the Countywide Planning Program Advisory Committee and were approved by the Ventura County Board of Supervisors on May 7, 1985. The locations that are not based on the growth and non-growth areas are described as follows:

  1. "North Zone of the District": as defined in Rule 7.

  2. "Outer Continental Shelf": as defined in Rule 26.1.
