18 AAC 50.201. Ambient air quality investigation . (a) Upon a finding by the department that emissions from an existing sta tionary source have a re asonable likelihood of causing or significantly contributing to ambient concentrations of one or more air pollutants that exceed an ambient air quality standard, maximum allowable increase, or the limitations of 18 AAC 50.110, the department may require the owne r, operator, or permittee to evaluate the effect of the stationary sour ce’s emissions of those air pollu tants on ambient air or on the

limitations of 18 AAC 50.110 that are at issue. An evaluation submitted under 18 AAC 50.306, 18 AAC 50.540, this section, or prior equivalent regulations, and deemed complete by the department, must satisfy the eval uation requirements of this secti on, and any prior analysis must accurately represent the stationary source’s emissions.

(b) Based on an evaluation submitted under (a) of this section or other information in the department's possession and subject to AS 46.14.010( e), the department may require an existing stationary source to reduce em issions or implement another control strategy to reduce the ambient impact of those emissions as necessary to ensure that the concen tration of air pollutants

in the ambient air does not exceed the ambien t air quality standards, maximum allowable increases, or the limitations of 18 AAC 50.110. A reduction or control strategy may be imposed as a source-specific permit cond ition or as a regulation. Before imposing a reduction or control strategy, the department will consult with the aff ected owner, operator, or permittee and provide the affected public an opportunity for comment a nd hearing. To the extent practicable, given theRegister 213, April 2015 ENVIRONMENTAL CONSERVATION

54 costs of determining an equita ble allocation, any emission reducti on or control strategy imposed under this section will be equita bly allocated among stationar y, mobile, and area sources and source categories based upon their relative contri bution to the ambient impacts of concern, the cost of additional controls, and other equitable factors.

(c) When determining whether to impose a redu ction or control strategy under (b) of this section, the department will consid er the uncertainties of ambien t air quality analysis, the costs and benefits of resolving the uncertainties, th e nature of the ambient impact area, and the proximity and magnitude of adjacent impacts.

(d) The provisions of this section do not a pply if the area affected by the emissions of an air pollutant is designated nonattainment for that air pollutant under 18 AAC 50.015.

(e) The provisions of this section do not limit the department’s ability to require or conduct ambient air quality analysis or control u nder the construction permit program established under AS 46.14.120 and this chapter. (Eff. 1/18/ 97, Register 141; am 10/ 1/2004, Register 171)

18 AAC 50.220. Enforceable test methods . (a) The department may require an owner, operator, or permittee to conduct air pollutant emission tests to determine compliance with AS 46.14 and this chapter. If an applicable emission standard, permit provision, or other requirement specifies a time period within which testing must be completed, the owner, operator, or permittee shall conduct the test ing within the specified peri od regardless of whether the department explicitly calls fo r testing under th is subsection.

(b) Unless otherwise specified by an applic able requirement or test method, an air pollutant emission test must be performed

(1) at a point or points that characterize the actual discharge into the ambient air;

and

(2) at the maximum rated burning or operating capacity of the emission unit or another rate determined by the department to ch aracterize the actual discharge into the ambient

air.

(c) Reference test methods to be used by the owner, operator, or permittee for an applicable requirement of AS 46.14 or this chapter are as follows:

(1) except as provided in (2) of this subsection,

(A) source testing for compliance with requirements adopted by reference in 18 AAC 50.040(a) must be conducted in accord ance with the source test methods and procedures specified in 40 C.F.R. Part 60, adopted by reference in 18 AAC 50.040(a);

(B) source testing for compliance with requirements adopted by reference in 18 AAC 50.040(b) must be conducted in acco rdance with the source test methods and procedures specified in 40 C.F.R. Part 61, adopted by reference in 18 AAC 50.040(b);

(C) source testing for complian ce with requirements adopted by reference in 18 AAC 50.040(c) must be conduc ted in accordance with the source test methods and procedures specifi ed in 40 C.F.R. Part 63, adopted by reference in 18 AAC 50.040(c);Register 213, April 2015 ENVIRONMENTAL CONSERVATION

58 (D) source testing for reduction in vi sibility through the exhaust effluent must follow the procedures set out in Vol. 3, sec. IV-3, Appendix IV-3, "Alaska Air Quality Visible Emissions Evaluation Procedures," of the state air quality control plan, adopted by reference in 18 AAC 50.030;

(E) source testing for emissions of total particulate matter, sulfur compounds, nitrogen compounds, carbon monoxide , lead, volatile organic compounds, fluorides, sulfuric acid mist, municipal wast e combustor organics, metals, and acid gases must follow the procedures specified in Appendix A to 40 C.F.R. Part 60, adopted by reference in 18 AAC 50.040; and

(F) source testing for emissions of PM-10 and PM-2.5 must follow the procedures set out in Appendix M to 40 C.F. R. Part 51, adopted by reference in 18 AAC 50.035;

(2) emissions of any air pollutant may be determined using an alternative method approved by the department in accordance with Method 301 in Appendix A to 40 C.F.R. Part 63, adopted by reference in 18 AAC 50.040(c); and

(3) standard exhaust gas volumes must in clude only the volume of gases formed from the theoretical combustion of the fuel, pl us the excess air volume normal for the specific emission unit type, corrected to standard conditions.

(d) In deciding whether to require a test under (a) of this secti on, the department will

consider

(1) the compliance status of the emissi on unit and the margin of compliance with each applicable requirement as demonstrated by prior compliance tests or other reasonably accurate data or calculations;

(2) the potential variability of emissi ons from the stationary source; and

(3) the date and results of prior compliance tests, if any.

three one-hour test runs. Th e source test must account for those emissions caused by soot blowing, grate cleaning, or other r outine maintenance activities by en suring that at least one test run includes the emissions caused by the rou tine maintenance activity and is conducted under conditions that lead to representative emissions from that activity. The emissions must be quantified using the following equation:Register 213, April 2015 ENVIRONMENTAL CONSERVATION

59 Where: E = the total particulate emissions of the source in grains per dry standard cubic foot (gr/dscf).

E M = the particulate emissions in gr/dscf measured during the test that included the routine maintenance activity.

E NM = the arithmetic average of particulat e emissions in gr/dscf measured by the

test runs that did not include routine maintenance activity. A = the period of routine maintenance activity occurring during the test run that included routine maintenance activity, expressed to the nearest

administration fees listed in this subsection. Pe rmittees will be invoiced in July for each period from July 1 through the following June 30. Each annual permit fee is one -fifth of the total original permit cost or total co st of permit renewal. For an initial Title V permit, the annual permit fee is collected starting the first July after the permit is issued. The following permit administration fees apply to Title V sources:

(1) for renewal of a permit for an oil- and-gas source with th e potential to emit more than 250 tons per year of any one pollutant, the

(A) annual permit fee is $2,675; and

(B) annual compliance review fee is $1,895;

(2) for renewal of a permit for a large pow er plant with the potential to emit more than 250 tons per year of any one pollutant, the

(A) annual permit fee is $3,080; and

(d) If the department prepares a new ge neral operating permit or a new general minor permit, the department will determine the cost of that permit by multiplying the number of hours the department spent to devel op the permit by the hourly rate of salary and benefits of the department employees who developed the permit. This cost will be divided by the number of permittees who receive or are expected to receive the permit to determine the permit

administration fee.

(e) The permittee, owner, or operator of a stationary source shall pay an annual compliance fee of $325, to be paid for each period from July 1 through the following June 30, for a stationary source that is not classified as needing a Title V permit and that isRegister 213, April 2015 ENVIRONMENTAL CONSERVATION

(a) For each period from July 1 through the following June 30, the permittee, owner, or operator shall pay to the department an annual emission fee based on the stationary source’s a ssessable emissions for that year for each stationary source that is subject to a permit under this chapter. The emissions fee is assessed per ton for each air pollutant for which projected emissions are 10 to ns per year or greater, except as limited under AS 46.14.250(e).

(b) Except as provided in (c), (f), and (g) of this section, emission fees will be assessed

as follows:

(1) for stationary sources require d to obtain an operating permit under AS 46.14.130(b), an emission fee rate of $28.57 pe r ton; of that per ton amount, $19.32 will be allocated to the clean air protection fund under AS 46.14.260, and $9.25 will be allocated to the emission control permit receip ts account under AS 46.14.265;

(2) for stationary sources not subject to (1)(A) of this subs ection but otherwise required to obtain a permit under AS 46.14.130, the emission fee rate of $9.25 per ton, which

will be allocated to the emissions c ontrol permit receipts account under

AS 46.14.265.

(c) The quantity of emissions for which fees will be assessed is the lesser of the stationary source’sRegister 213, April 2015 ENVIRONMENTAL CONSERVATION

The emission fee is based on assessable emissions for the state fiscal year being assessed and is billed in July of that year. The

entire fee is allocated to the emission control permit receipts account under AS 46.14.265. The annual emission fee rate is $9.25 per ton.

(g) Notwithstanding (a) - (d) of this section, for the projec ted annual rate of emissions for a portable oil and gas operation under a general minor permit under 18 AAC 50.560, the

emission fee is allocated to the emission control permit receipts account under AS 46.14.265, and the permittee shall pay the emission fee

(1) at the time of application or notif ication for operation that will occur in the same state fiscal year;

(2) for operation that will occur during more than one state fiscal year under a single application or notific ation, after billing under 18 AAC 50.420 by the department for any subsequent state fiscal year; and

(3) at the following rates for a single por table oil and gas operation for which the owner or operator submits a new application or notification for ope ration under the general minor permit on or after December 3, 2005:Register 213, April 2015 ENVIRONMENTAL CONSERVATION

However, for reviews of excess emission reports, the department will bill on a semiannual basis if requested in writing by the person required to pay the fee.Register 213, April 2015 ENVIRONMENTAL CONSERVATION

116 (c) Fees assessed under this chapter are due with in 60 days after the billing date. A payment that is past due accrues interest at the rate set in AS 46.14.255 unless the person required to pay the fee successfully disputes the fee or a portion of the fee under 18 AAC 50.430. Interest will be charged on the unpaid balance, beginning on the 61st day after the billing date.

(d) A person required to pay an emissi on fee under 18 AAC 50.410 may pay that fee in equal quarterly installments if

(1) the fee exceeds $1,000; and

(2) a written request is submitted to th e department with the first installment

before the due date describe d in (c) of this section.

(e) If installment payments are requested under (d) of this secti on, the remaining three installments, including interest ac crued as described in (c) of th is section, must be paid on or before October 15, January 15, and April 15 of each year.

(f) An owner, operator, or permittee who

(1) increases a stationary source's assessable emissions through a permit revision shall pay to the department an emission fee for the increase in assessable emissions; the fee is due within 60 days after the effectiv e date of the permit revision; or

(2) decreases the stationary source's assessable emissions through a permit revision may request a prorated refund or credit to the stationa ry source's fee account toward

future fees.

(g) The owner, operator, or permittee who terminates operations or whose permit has lapsed or is terminated by the department may request a refund calculated by the department for

fees collected in excess of the amount due for the stationary s ources' actual emissions.

(h) Unless the owner, operator, or permittee requests otherwise, an invoice for emission fees or permit administration fees will be sent to the last known address of the stationary source that is subject to the fee. In an invoice, th e department will include an itemized list of charges and credits for the billing peri od and a calculation of total credit balance or amount due on the account. For permit administration fees fo r designated regulatory services under 18 AAC 50.400(j), the department will also in clude as part of the itemized list the

121 (e) For the purposes of (c)(3)(B ) of this section, actual emissions shall be calculated by comparing projected actual emissions to the ba seline actual emissions. In determining the projected actual emissions, before beginning ac tual construction, the ow ner or operator of the stationary source shall

(1) consider all relevant information, in cluding historical op erational data, the owner’s or operator’s own repres entations, the owner’s or operat or’s expected business activity and the owner’s or operator’s highest projections of business activity, the owner’s or operator’s filings with the state or federal regulato ry authorities, and co mpliance plans under AS 46.14.120; and

(2) include fugitive emissions to the exte nt quantifiable and emissions associated with startups, shutdowns, and malfunctions; and

(3) exclude, in calculating any increase in emissions that results from the particular project, that portion of the unit's em issions following the project that an existing unit could have accommodated during th e consecutive 24-month period used to establish the baseline

actual emissions and that are also unrelated to the particular project, including any increased utilization due to product demand growth.

(f) If the owner or operator elects to base permit applic ability for a modification on a calculation of actual emissions, if the project does not need a minor permit based on that calculation, and if a reasonable pos sibility exists that the proj ect may result in an emissions increase greater than the thresholds in (c)(3) of this section, the owner or operator shall comply with the following:

(1) before beginning actual construction of the project, the owner or operator

shall document and maintain a reco rd of the following information:

(A) a description of the project;

(B) identification of eac h emission unit that has emissions of a regulated NSR pollutant that could be affected by the project; and

(2) if the emission unit is an existing el ectric utility steam generating unit, before beginning actual construction, the owner or operator shall provide a copy of the information listed in (1) of this subsection to the department;

(3) the owner or operator shall monito r the emissions of any regulated NSR pollutant that could increase as a result of th e project and that is emitted by any emission unit identified in (1)(B) of this subsection, and shal l calculate and maintain a record of the annualRegister 213, April 2015 ENVIRONMENTAL CONSERVATION

122 emissions, in tons per year on a calendar year basis, for a period of five years following resumption of regular operations after the project, or for a period of 10 years following resumption of regular operations after the project if the project increases the design capacity of or potential to emit that regulated NSR pollutant at that emission unit;

(4) if the emission unit is an existing electric utility steam generating unit, the owner or operator shall submit a report to the department within 60 days after the end of each year during which records must be generated under (3) of this subsection setting out the unit's annual emissions during the calendar year th at preceded submission of the report.

(5) if the emissions unit is an existing unit other than an electric utility steam generating unit, the owner or ope rator shall submit a report to the department if the annual emissions, in tons per year, from the project id entified in (1) of this subsection, exceed the baseline actual emissions, as documented and ma intained under (1)(C) of this subsection, by an amount exceeding the thresholds in (c)(3) of this section for that regulate d NSR pollutant, and if

those emissions differ from the reconstruction projection as documented and maintained under (1)(C) of this subsection; the repor t shall be submitted to the department within 60 days after the end of that year; the report must contain the following:

(A) the name, address, and telephon e number of the stationary source;

(B) the annual emissions as calcula ted under (3) of this subsection;

(C) any other information that the ow ner or operator wishes to include in the report.

(g) An increase in emissions under (c)(3) of this section does not require a permit under that paragraph if a plantwide applicability limitation (PAL) is established for the stationary source under 40 C.F.R. 52.21(aa), adopted by reference in 18 AAC 50.040.

(B) the calculation of whether a modification requires a minor permit under (c)(3) of this sec tion, rather than whether the modification is a major modification;

(4) “projected actual em issions” means the maximum annual rate, in tons per year, at which an existing emission unit is project ed to emit a regulated NSR pollutant in any one of the five 12-month periods following the date the unit resumes regular operation after the project, or in any one of the 10 years following that date, if the project involves increasing the emissions unit's design capacity or the potential to emit that regulated NSR pollutant and full

utilization of the unit would result in an emissions increase or a net emissions increase greater than a threshold in (c)(3) of this section.

(5) “regulated NSR pollutant” has the meaning given in 40 C.F.R. 52.21(b)(50), adopted by reference in 18 AAC 50.040(h).

(B) that have vehicle and roadwa y emission and dispersion characteristics essentially identical to those at sites th at have air quality violations verified by monitoring, and that, therefore, require a quantitative PM-10 or PM-2.5 hot-spot analysis;

and

(7) notify staff of participating agenci es of any revision or amendment to a transportation plan or TIP that merely adds or deletes an exempt project listed in 40 C.F.R. 93.126, adopted by reference in 18 AAC 50.710.

(d) In addition to the consultation described in (c) of this section, a staff member of the responsible agency shall consult with staff of the state and local agencies listed in (a)(2) of this

household or travel tr ansportation surveys.

(e) If the metropolitan pl anning area does not include the entire nonattainment or maintenance area, the interage ncy consultation must include staff of the local governing body and the Alaska Department of Tr ansportation and Public Facilities to determine conformity of all projects outside the metropolitan planning area and within the nonattai nment or maintenance

area. (f) After completing the interagency consulta tion process, the res ponsible agency shall prepare the public review draft of the conformity determination, based on changes made to the preliminary draft during the c onsultation process, and shall make the public review draft available for public review and co mment as required in 18 AAC 50.720.Register 213, April 2015 ENVIRONMENTAL CONSERVATION

146 (g) After opportunity for public review a nd comment on the public review draft of the conformity determination, the responsible agency shall

(1) prepare a final draft of the conformity determination in consultation with staff of the participating agencies; and

(2) after the consultation described in (1) of this subsection, issue the final conformity determination to the agencies liste d in (a)(2) of this section and provide the supporting information upon request.

(h) The department will refer to the gover nor for resolution any conflict between state agencies or between state and lo cal agencies that cannot be reso lved by the heads of the involved agencies. The department will make the referral to the governor within 14 calendar days after

notification or a determination th at the conflict cannot be resolve d. A conformity determination that is the subject of a conflict resolution under this s ubsection must have the governor's
