COLUSA COUNTY AIR POLLUTION CONTROL DISTRICT
REGULATION III - PERMITS
RULE 3.6 - STANDARDS FOR AUTHORITY TO CONSTRUCT (NEW SOURCE REVIEW)
(Adopted 09/14/93)
a. GENERAL
A. The purpose of this rule is to establish preconstruction review requirements for new and modified stationary sources of air pollution for use of Best Available Control Technology (BACT), analysis of air quality impacts, and to ensure that the operation of such sources does not interfere with the attainment or maintenance of ambient air quality standards;
B. This regulation shall provide for no net increase in emissions, pursuant to Section 40918 of the California Health and Safety Code, from new or modified stationary sources that emit, or have the potential to emit, 25 tons per year or more of any nonattainment pollutant or its precursors.
b. DEFINITIONS
For the purpose of this rule, the definitions below shall apply:
A. Emission reductions shall be real, enforceable, quantifiable, and permanent.
B. Emission reductions shall be in excess of any emission reductions that are:
Actual emission reductions attributed to a proposed control measure, may be re-eligible as actual emission reduction in the following circumstances:
A. For control measures identified in the District Air Quality Attainment Plan or State Implementation Plan, no rule has been adopted within two (2) years from the scheduled adoption date provided, however, the Air Pollution Control Officer (APCO) has not extended the scheduled adoption date;
B. For control measures not identified in the District Air Quality Attainment Plan or State Implementation Plan, no rule has been adopted within two (2) years from the date of the latest public workshop notice.
"Affected pollutants" are all air pollutants for which an ambient air quality standard has been established by the U.S. Environmental Protection Agency (EPA) or the California Air Resources Board (ARB), and the precursors to such pollutants.
A. The most effective emission control device, emission limit, or technique that has been required or used for the type of equipment comprising such emissions unit unless the applicant demonstrates to the satisfaction of the APCO that such limitations are not achievable; or
B. Any other emission control device or technique, alternative basic equipment, different fuel or process, determined
to be technologically feasible and cost- effective by the APCO. The cost-effective analysis shall be performed
in accordance with the methodology and criteria specified by the APCO;
Under no circumstances shall BACT be determined to be less stringent than the emission control required by any
applicable provision of District, State, or Federal laws or regulations, unless the applicant demonstrates to the
satisfaction of the APCO that such limits are not achievable.
A. Contained in the latest Authority to Construct and contained in or enforceable by the latest Permit to Operate for the emission unit; and
B. Enforceable on a daily basis; and
C. Established pursuant to a permitting action occurring after September 14, 1993, and used in the calculation of the net emission change.
A. cyclic, branched, or linear, completely fluorinated alkanes,
B. cyclic, branched, or linear, completely fluorinated ethers with no unsaturations,
C. cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations, and
D. saturated perfluorocarbons containing sulfur with sulfur bonds only to carbon and fluorine.
Perfluorocarbon compounds will be assumed to be absent from a product or process unless a manufacturer or facility operator identifies the specific individual compounds (from the broad classes of perfluorocarbon compounds), and the amounts present in the product or process, and provides a validated test method that can be used to quantify the specific compounds.
The following shall not be considered a modification:
A. Routine maintenance or repair.
B. A change in ownership.
C. Replacement of an existing emissions unit, part of an emissions unit, or emissions control device with a functionally identical piece of equipment resulting in emissions less than or equal to those from the original equipment or device and not requiring a change in permit conditions.

A. Offsets shall be required for a new stationary source with a potential to emit, calculated pursuant to Section d.4., of nonattainment pollutants or their precursors equal to or exceeding twenty-five (25) tons per year. The amount of offsets required shall be at least equal to that portion of the potential to emit that exceeds 25 tons per year.
B. Offsets shall be required for a modified stationary source under the following conditions:
C. Offsets shall not be required for increases in carbon monoxide if the applicant demonstrates to the satisfaction of the APCO, through an impact analysis, that the Ambient Air Quality Standards are not violated in the areas to be affected, and such emissions will not cause or contribute to a violation of Ambient Air Quality Standards.
D. In no case shall halogenated hydrocarbons be used as offsets.
Offset ratio and the corresponding distances from the proposed stationary source shall be:
A. On-site, at a ratio of 1:1;
B. Within 20 miles, at a ratio of 1.2:1;
C. 20 to 50 miles, at a ratio of 1.5:1;
D. Over 50 miles, at a ratio of 2:1.
Use of offsite offsets must result in a net air quality benefit, as determined by the APCO.
Offsets that are obtained from a source located in another district may be used only if the provisions of Health
and Safety Code 40709.6 are met, and the involved districts enter into an agreement formalized by a memorandum
of understanding.
A. Interpollutant trades between PM10 and PM10 precursors may be allowed. PM10 emission reductions shall not be allowed to offset NOx or reactive organic compound (ROC) emissions increases in ozone nonattainment areas.
B. The PM10 emissions from an existing stationary source shall be recalculated from the TSP emissions increases and decreases which have occurred since August 20, 1983 using applicable PM10 emission factors. When applicable PM10 emission factors do not exist, assume 50 percent of TSP is PM10.
C. If the applicant has provided full offsets for TSP emissions occurring since August 20, 1983, but before September 14, 1993, those TSP emissions need not be recalculated as PM10. However, any subsequent emissions increase in PM10 emissions shall be subject to the offset requirements of the rule.
d. CALCULATIONS
A. The emission change for all new or modified emissions units; and
B. Actual emission reductions (AERs) for all shutdowns and modified emission units; and
C. The cumulative emissions increase from all new and modified emission units for a stationary source.
A. Calculate the emission change for each new or modified emissions unit and for each pollutant using Section d.3. of this rule.
B. If an increase is calculated for a pollutant, follow the requirements in:
C. If a decrease is calculated for a pollutant, go to Section d.3.B. to determine if emission reduction credits (ERCs) are generated.
D. For no change in emissions, no further calculations are required.
A. EMISSIONS INCREASE
Emissions change = (proposed emissions) - (historic potential emissions)
B. ACTUAL EMISSIONS REDUCTIONS (AER)
AER = Historic actual emissions
AER = (historic actual emissions) x (control efficiency)
AER = (historic actual emissions) - (proposed emissions)
e. AIR QUALITY IMPACT ANALYSIS
In no case shall emissions from a new or modified emissions unit, cause or make worse the violation of an Ambient Air Quality Standard. The APCO may require an applicant to use an air quality model to estimate the effects of a new or modified emissions unit. For the purpose of performing an impact analysis the following shall apply:
f. ADMINISTRATIVE REQUIREMENTS
The following administrative requirements shall apply to this Rule:
g. POWER PLANTS
A. A preliminary specific definition of BACT for the proposed facility; and
B. A preliminary discussion of whether there is substantial likelihood that the requirements of this rule and all other District regulations can be satisfied by the proposed facility; and
C. A preliminary list of conditions that the proposed facility must meet in order to comply with this Rule and
any other applicable District regulations.
The preliminary determinations contained in the report shall be as specific as possible within the constraints
of the information contained in the NOI.
A. Whether the proposed power plant meets the requirements of this rule and all other applicable District regulations; and
B. In the event of compliance, permit conditions will be required, including the specific BACT requirements
and a description of required mitigation measures.
The preliminary written decision under Section f.5. of this rule, shall be treated as a preliminary decision under
Section f.3. of this Rule, and shall be finalized by the APCO only after being subject to the public notice and
comment requirements of Sections f.4. through f.6. The APCO shall not issue a Determination of Compliance unless
all requirements of this rule are met.
