1.0 PURPOSE

1.1 The purpose of this Rule is to establish pre

- construction review requirements for new and modified stationary sources of air pollution and to provide mechanisms, including emission offsets, by which authorities to construct for such sources may be granted without interfering with the attainment or maintenance of a mbient air quality standard s

.

1.2 This Rule shall provide for no net increase in emissions, pursuant to Section 40918 of the California Health & Safety Code (HSC), from new or modified stationary sources which emit, or have the potential to emit, 25 tons per year or more of any non

- attainment pollutant or its precursors. [ Note: This subsection will not be included in the Federal SIP submittal of this rule.]NORTH COAST UNIFIED AQMD RULES AND REGULATIONS

2.1 This Rule shall apply to all new stationary sources and emission units and all

modifications to existing stationary sources and emissions units that , after construction, emit or may emit any affected pollutant within the District.

2.1.1 The regulations in effect at the time an y application for an Auth o r ity t o Construct for a new or modified source is deemed complete shall apply to that source except when a new federal requirement not yet incorporated into this Rule applies to the new or modified source. In such a case, the new federal rules shall apply to the source

.

2.2 Any facility or source subject to this rule which has ceased operation for two or more continuous years, excluding minimal maintenance activities, shall be presumed to have been permanently shutdown.

2.2.1 Any permanently shutdown facility or source which th en seeks reactivation is subject to re

- evaluation under the requirements of Rule 110,

NSR a nd PSD, including the requirement for BACT, offsets and modeling, as applicable.

2.2.2 The presumption a facility is permanently shutdown is refutable, and the burden of disproving the presumption rests with the permittee. In rebutting this presumption, the APCO shall take into consideration the totality of the circum stances including but not limited to: intent of the owner or operator, age of the facility , likelihood of reactivated operations may cause or contribute to a public nuisance, conflicting statements of intent by the owner and operator, frequency of equipment and facility upsets and equipment breakdowns, and ongoing maintenance.

2.2. 3 E very facility and source subject to the provisions of this R ule which has not operated for five (5) or more continuous years shall be considered permanently shutdown for the purposes of this Rule

of non

- attainment pollutants or their precursors associated with a new or modified stationary source and shall be determined as follows:

5.2.1 Offsets shall be required for a new stationary source with a potential to emit, calculated pursuant to Section 6.5 of this Rule

, non

- attainment pollutants or their precursors equal to or exceeding 25 tons per year. The amount of offsets required shall be at least equal to that portion of the potential to emit which exceeds 25 tons per year.

5.2.2 Offsets shall be required for a mod ified stationary source under the following conditions:

5.2.2.1 An existing stationary source which has a potential to emit less than 25 tons per year as of January 12, 1993, of non

- attainment pollutants or their precursors shall offset that port ion of the stationary source's potential to emit which, after modification of the stationary source, exceeds 25 tons per year from new or

modified emissions unit s. A stationary source's poten tial to emit shall be calculated pursuant to Section 6 .5 of this Rule . After the potential to emit for a stationary source has exceeded these levels, and the applicant has provided actual emissions reductions to offset emission increases in excess of these levels, all future

increases from new or modified em issions units shall be offset; and

5.2.2.2 An existing stat ionary source which has a poten tial to emit, calculated pursuant to Section 6.5 of this Rule

, of non

- attainment pollutants or their precursors equal to or exceeding 25 tons per year as of January 12, 1993, shall offset any increases in potential to emit resulting from the permitting of a new or modified emis

sions unit.

5.2.3 Offset requirements for increases in carbon monoxide: Offsets shall not be required for increases in carbon monox ide if the appl icant demonstrates

to the satis faction of the APCO, through an impact analysis, that theNORTH COAST UNIFIED AQMD RULES AND REGULATIONS

December 9, 2010 110

- 10

ambient air quality standards are not violated in the areas to be affected

, and such emissions will not cause or contri bute to a violation of N ational

A mbient A ir Q uality S tandards

.

5.3 Location of Offsets and Offset Ratios

5.3.1 Offset ratios and the corresponding distances from the proposed stationary

source shall be:

5.3.1.1 on

- site, at a ratio of 1:1;

5.3.1.2 within 20 miles, at a ratio of 1.2:1;

5.3.1.3 from 20 miles to 50 miles, at a ratio of 1.5:1;

5.3.1.4 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.

5.3.2 Offsets which are obtained from a source located in another District may be used only if the provisions of C H & S Code Section 40709 .6 are met

, EPA approval is obtained and the involved Districts enter into an agreement formalized by a memorandum of understanding.

5.4 Inter

- pollutant Offsets: The APCO may approve inter

- pollutant offsets on a

case

- by

- case basis, provided that the applicant demonstrates to the satisfaction of the APCO, through the use of an impact analysis, that the emission increases from the new or modified source will result in a net air quality benefit and will not cause or contribute to a violation of any air quality standard. In such cases, the

APCO m ay, based upon an air quality analysis, impose offset ratios greater than the requirements of this Rule. The project must also obtain EPA approval for the

use of inter

- pollutant offsets.

5.5 Ambient Air Quality Standards: In no case shall the emissions from the new or modified stationary source cause or worsen the violation of an ambient air quality

standard . An impact analysis may be used to estimate the effects of a new or modified source. In making this determination, the APCO shall take i nto account the mitigation of emissions through offsets obtained pursuant to this Rule.

5.6 Denial, Failure to Meet Standards: The AQMD shall deny any Authority to Construct or Permit to Operate if the APCO finds that the subject of the application would not comply with the standards set forth in this Rule.

5.7 Compliance by Other Owned, Operated, or Controlled Sources: The owner or operator of a proposed new or modified source shall certify to the APCO that all sources having a potential to emit in e xcess of 100 tons per year that are owned or operated by such person (or by an entity controlling, controlled by, or under common control) in California are in compliance, or on a schedule for compliance, with all applicable emission limitations and stan dards.NORTH COAST UNIFIED AQMD RULES AND REGULATIONS

- 11 6 .0 CALCULATIONS

6.1 Purpose: The following calculations procedures shall be used to determine:

6.1.1 the emissions change for all new or modified emissions units; and

6.1.2 actual emissions reductions for all shutdowns and modified emissions units; and

6.1.3 the cumulative emissions increase from all new and modified emissions units for a stationary source.

6.2 Definitions: The following terms are used in the calculations procedure and are

defined as follows:

6.2.1 Control Efficiency means the estimated control efficiency of the proposed air pollution control technology which will be incorporated, by means of (an) enforceable permit condition(s), in the Authority to Construct and Permit to Operate. Emission reductions attri buted to lowering throughput rates or operating hours shall not be considered in determining control efficiency.

6.2.2 Historic Actual Emissions means actual emissions averaged over the two (2) year period immediately preceding the date of appli cation. If the last two (2) years are unrepresentative of normal operations as determined by the APCO, then two (2) consecutive years of the last five (5) years may be used. Where an emissions unit has been in operation for less than two (2) years, a sho rter averaging period of at least one (1) year may be used, providing it represents the full operational history of the emissions unit. If, at any time during the specified period, actual emissions exceeded allowed emission levels, then actual emissions s hall be reduced to reflect emission levels that would have occurred if in compliance with all applicable limitations and rules.

6.2.3 Historic Emissions means the potential to emit of an existing emissions unit prior to modification. For a new emissions unit, historic emissions are equal to zero.

6.2.4 Proposed Emissions means the potential to emit for a new or post

modification emissions unit.

6.3 Procedure: The calculation procedure shall be performed separately for each pollutant and each emissions unit. Emission increases and decreases shall be calculated separately for each calendar quarter pursuant to the following procedure:

6.3.1 Calculate the emissions change for each new or modified emissions unit

and for each pollutant using Section 6.4 of this Rule.

6.3.2 If an increase is calculated for a pollutant, follow the procedures in

Sections 5. 2 of this Rule to determine the amount of offsets required.NORTH COAST UNIFIED AQMD RULES AND REGULATIONS

December 9, 2010 110

- 12

6.3.3 If a decrease is calculated for a pollut ant, follow the procedures in Section 6.4.2 of this Rule to determine if emission reduction credits (ERC's) are generated. If no emissions change is calculated for a pollutant, no further calculations are required.

6.4 Calculating Emissions Changes

6.4.1 Emissions Increase

6.4.1.1 New or Modified Emissions Unit: The emissions change for a

new or modifie d emissions unit shall be calcu lated by subtracting

historic emissions from proposed emissions:

Emissions chan ge = Proposed emissions minus Historic

E missions

6.4.2 Actual Emissions Reductions (AER)

6.4.2.1 Shutdown of an Emissions Unit:

AER = Historic actual emissions

6.4.2.2 Modification consisting solely of application of control equipment or implementation of more efficient process:

AER = Historic actual emissions multiplied by Control efficiency

6.4.2.3 Other Modifications:

AER = Historic actual emissions minus Proposed emissions

6.5 Reserved

7 .0 AIR QUALITY IMPACT A NALYSIS: In no case shall emissions from a new or

modified emissions unit cause or worsen 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 a pply:

7.1 Air quality models shall be consistent with the requirements specified in 40 CFR Part 51, Appendix W (“Guid eline on Air Quality Models ”)

, unless the APCO finds that such model is inappropriate for use. After making such a finding, the APCO may designate an alternative model only after allowing for public comment and only with the written concurrence of CARB and EPA. AllNORTH COAST UNIFIED AQMD RULES AND REGULATIONS

December 9, 2010 110

- 13

modeling costs ass ociated with the site of a new or modified emissions unit shall be borne by the applicant

. In addition, use of a modified or substituted model must be subject to notice and opportunity for public comment.

7.2 In performing an impact analysis, if the pro posed stack height is higher than is dictated by good engineering practices, the actual height used for the purposes of modeling shall be calculated in accordance with good engineering practices.

of the State of California.

8.5 Denial, Failure To Meet Standards: The APCO shall deny any Authority to Construct or Permit to Operate if the APCO finds that the subject of the application would not comply with the standards set forth in District, state, or federal rules or regulations.

8.6 Authority to Construct, Final Ac tion: Within 180 days after acceptance of an application as complete, the APCO shall take final action on the application after considering all written comments. The APCO shall provide written notification of the final action to the applicant, CARB, and EPA, and shall make the

notification and all supporting documents available for public inspection at the AQMD office s for all Authorities to Construct issued for emissions units subject to the requirements of Section 5. 1 of this Rule.

8.7 Requ irements for Permit s to Operate: As a condition for the issuance of a Permit to Operate, the APCO shall require that the new source or modification, and any sources which provide offsets will be operated in the manner assumed in making the analysis to determine compliance with this Rule. The Permit to Operate shall include daily emissions limitations which reflect applicable emissions limitations, including BACT. As a condition for the issuance of a Permit to Operate, any stationary source which provides emission offsets shall be subject to enforceable permit conditions, containing specific emissions limitations, and/or operational limitations which ensure that the emission reductions will be provided in accordance with the provisions of this Rule and

shall continue for the rea sonably expected life of the proposed source. When the source of offsets is not subject to a permit, a written contract shall be required between the applicant and the owner or operator of such offset source, which contract, by its terms, shall be enforce able by the APCO. A violation of the emission limitation provisions of any such contract shall be chargeable to the applicant.

8.7.1 Where the source of offsets is a non

- permitted source, the AQMD shall require the non

- permitted source to obtain an enforceable permit, complete with operational and emission limitations. If the source of offsets is a permit

- exempt piece of equipment, that particular source must relinquish its exempt status.NORTH COAST UNIFIED AQMD RULES AND REGULATIONS

8.7.2 If the AQMD, pursuant to state laws or AQMD Regulat ions, cannot permit the source of offsets, the source creating the offsets shall execute a legally binding contract between the applicant and the owner or operator of such offset source, which contract, by its terms, shall be enforceable by

the APCO. A vi olation of the emission limitation provisions of any such contract shall be chargeable to the applicant. [ Note: This subsection will not be included in the Federal SIP submittal of this rule.]

8.8 Issuance of Permit s to Operate: The APCO shall issue a Permit to Operate for any stationary source which meets the requirements of this Rule.

Any offsets required as a condition of an Authority to Construct or amendment to a Permit to Operate shall commence not later than the initial operation of the new or modified source, and the offsets shall be maintained throughout the operation

of the new or modified source which is the beneficiary of the offsets. Further, the APCO shall determine that all conditions specified in the Authority to Construct have been or will be complied with by any dates specified. Where a new or modified stationary source is, in whole or part, a replacement for an existing stationary source on the same property, the APCO may allow a maximum of one hundred and eighty (180 ) days as a start

- up period for simultaneous operations of the existing stationary source and the new source or replacement.

8.9 Reserved.

8.10 Permit Conditions: The APCO shall have the authority to place conditions on the Authority to Construct and/or Permit to Operate which will ensure that the construction, modification, or operation of such source will comply with all applicable rules and regulations. Such c onditions may include, but not be limited to: hours of operation; processing parameters; periods of use; and emission limitations on an hourly, daily, or yearly basis.

9 POWER PLANTS REVIEW PROCEDURES : A power plant shall be defined as a stationary sourc e that produces electricity.

This section shall apply to all power plants proposed to be constructed in the district and

for which a Notice of Intention (NOI) or Application for Certification has been accepted by the California Energy Commission (CEC). The APCO may apply for reimbursement of all costs incurred, including lost fees, in order to comply with the provisions of this

section.

9.1 Intent to Participate and Preliminary Report: Within fourteen (14) days of receipt of an NOI, the APCO shall notify CARB and the CEC of the AQMD 'S intent to participate in the NOI proceeding. If the AQMD chooses to participate

in the NOI proce eding , the APCO shall prepare and submit a report to CARB and the CEC prior to the conclusion of the non

- adjudicatory hearing specified inNORTH COAST UNIFIED AQMD RULES AND REGULATIONS

Section 25509.5 of the Public Resources Code. That report shall include, at a

minimum:

9.1.1 A preliminary specific definition of BACT for the proposed facility; and

9.1.2 A preliminary discussion of whether there is a substantial likelihood that the requirements of this Rule and all other AQMD Regulations can be satisfied by the proposed facility; and

9.1.3 A preliminary list of conditions which the proposed facility must meet in order to comply with this Rule or any other applicable AQMD Regulation.

The preliminary determinations contained in the report shall be as specific as possible within the constraints of the information contained in the NOI.

9.2 Determination of Compliance Review: Upon receipt of an Application for Certification (AFC) for a power plant, the APCO shall conduct a Determination of Compliance review. This de termination shall consist of a review identical to that which would be performed if an application for an Authority to Construct had been received for the power plant. If the information contained in the AFC does not meet the requirements of this Rule, th e APCO shall, within twenty (20) calendar days of receipt of the AFC, so inform the Commission, and the AFC shall be considered incomplete and returned to the applicant for re

- submittal.

9.3 Equivalency of Application: The APCO shall consider the AFC to be equivalent to an application for an Authority to Construct during the Determination of Compliance review, and shall apply all provisions of this Rule which apply to an application for an Authority to Construct.

9.4 Need for Additional Information: The APCO may request from the applicant any information necessary for the completion of the Determination of Compliance review. If the APCO is unable to obtain the information, the APCO may petition the presiding Commissioner for an order direc ting the applicant to supply such

information.

9.5 Preliminary Determination: Within 180 days of accepting an AFC as complete, the APCO shall make a preliminary decision on:

9.5.1 whether the proposed power plant meets the require ments of this Rule and all other applicable D istrict Regulations; and

9.5.2 in the event of compliance, what permit conditions will be required, including the specific BACT requirements and a description of required mitigation measures. The preliminary written decision under Section 8. 3 of this Rule shall be treated as a preliminary decision under Section 9.5o f this Rule, and shall be finalized by the APCO only after being subjec t to the public notice and comment requirements of Sections 8.4 through 8.6 of this Rule. The APCO shall not issue a Determination of Compliance unless all requirements of this Rule are met.NORTH COAST UNIFIED AQMD RULES AND REGULATIONS

December 9, 2010 110

- 17 9.6 Determination of Compliance: Within 240 days of the filing date, the APCO shall issue and submit to the Commission a Determination of Compliance or, if such a determination cannot be issued, shall inform the CEC. A Determination of Compliance shall confer the same rights and privil eges as an Authority to Construct only when and if the Commission approves the AFC, and the

Commission certificate includes all conditions of the Determination of Compliance.

9.7 Permit to Operate: Any applicant receiving a certificate from the CEC Pur suant to this Section and in compliance with all conditions of the certificate shall be issued a Permit to Operate by the APCO.

10.0 EXCLUSIONS:

10.1 New Source Review Procedures in accordance with Rule 110 shall not be required for temporary stationary sources which will be in operation for less than 90 days duration provided BACT is applied in accordance with Section 5.1 and such operations will not interfere with the control strategy of the SIP.

10.2 Reserved.

11.0 PREVENTION OF SIGNIFICANT DE TERIORATION (PSD):

The provisions of this secti on shall only apply to new or modified sources which have the potential to emit greater than the applicable annual s ignificance t hreshold of the NSR Regulated Pollutant ( s ) listed in Table 1.0 Significance Thresholds of Section 5.1

.

11.1 Pursuant to the Federal Clean Air Act in addition to any other requirements imposed in these rules and regulations, and not withstanding any other permit requirements, no sources subject to these rules and regu lations shall be permitted to release emissions into the atmosphere which cause or create an exceedance of the maximum allowable prevention of significant deterioration (PSD) increments for Class I, Class II, or Class III areas as defined in Regulation I, Rule 101

.

11.2 An air quality analysis of the ambient impacts associated with the construction and operation of the proposed new source or modification shall be prepared to
de termine if the new emission emitted from the proposed major source or, modification, in conjunction with other applicable emissions from existing sources (including secondary emission from growth associated with the new project), will not cause or contribu te to a violation of any PSD increment.

11.3 A separate air quality analysis must be submitted for each regulated pollutant if the applicant proposes to emit a pollutant in a significant amount from a new major stationary source, or proposes to cause a s ignificant net emission increase from a major modification.NORTH COAST UNIFIED AQMD RULES AND REGULATIONS

December 9, 2010 110

- 18 11.4 Generally, the air quality analysis shall involve; (1) an assessment of existing air quality, which may include ambient air monitoring date and air quality dispersion modeling result, and (2) predictions, using dispersion modeling, of ambient

concentrations that will result from the applications proposed project and future growth asso ciated with the project.

11.5 All increment consumptions shall be determined using a baseline emission date established as a reference point for determining air quality deterioration in an area. The baseline concentration is pollutant specific and is es sentially the air quality level existing at the time of the first complete PSD permit application submittal in the AQMD. On or before the first PSD application, emissions are considered to be part of the baseline concentration, and emissions changes aft er that date affect the amount available PSD increments.

11.6 The amount of PSD increment that has been consumed in a PSD area is

determined from the emissions increases and decrease s which have occurred from sources since the applicable baseline date. In order to determine the amount of PSD increment consumed (or the amount of available increment), no determination of the baseline concentration needs to be made. Instead, increment consumption calculations must reflect only the ambient p ollutant concentration change attributable to increment

- affecting emissions. Emissions increases that consume a portion of the applicable increment are, in general, all those not

accounted for in the baseline concentr ation and specifically include a ctual

emissions increased occurring after the major source baseline date, which are associated with physical changes or changes in the method of operation ( i.e.

, construction) at a major stationary source. The amount of available increment may be added to, or “expanded”.

11.7 From the reduction of actual emissions after the major source baseline date, if the reduction results from a physical change or change in the method of operation (i.e., construction) at a major stationary source. The reduction will add to the available increment only if th e reduction is included in the federally enforceable permit or SIP provision.

11.8 The credible increase of an existing stack height or the application of any other credible dispersion technique may affect increment consumption or expansion in

the same m anner as an actual emissions increase or decrease. (The effects that a change in the effective stack height would have on ground level pollutant concentrations generally should be factored into increment analysis.) Any increase in a stack eight, in order to be creditable, must be consistent with the EPA’s stack height regulations; credit cannot be given for that portion of the new height which exceeds the height demonstrated to be the good engineering practice (GEP) stack height.NORTH COAST UNIFIED AQMD RULES AND REGULATIONS

December 9, 2010 110

- 19 11.9 Increment consum ption (and expansion) will generally be based on changes in actual emissions reflected by the normal source operation for a period of 2 years. However, if the little or no operating data are available, as in the case of permitted emission units not yet in operation at the time of the increment analysis, the potential to emit must be used instead.
