Preliminary Drafts – Serious SIP Development
The Alaska Department of Environmental Conservation (ADEC) is providing preliminary drafts of the following documents for public discussion. Please note the Preliminary Draft Step in the simplified State Implementation Plan (SIP) development and opportunities for public input below. These documents are a work in progress. DEC hopes to receive additional information from the public due to the release of the preliminary draft documents and expects to make changes to documents based upon this input. It is likely that the version of these documents released for formal public comment as part of the draft Serious SIP will have changes.
- No decisions yet, no regulations in this package
- Very early in the SIP Development
- Broad look at all possible measures for all sources
- Looking for additional data from Point Sources, Businesses, and Public
- Seeking additional data to assist in the overall analysis of the economic impacts and overall benefits of controls
- Work continues on assessing possible solutions and how the area can achieve attainment
- Additional information, to assist in completing the documents, may be submitted to: email@example.com until May 23, 2018.

These documents, once finalized, will be used to produce the SIP for the Fairbanks North Star Borough (FNSB) Serious nonattainment area:
- Preliminary Draft Concepts and Approaches
- Preliminary Draft Baseline Emission Inventory
- Preliminary Draft Technical Analysis Protocol (TAP)
- Preliminary Draft Modeling Protocol
- Preliminary Draft Precursor Demonstrations
- Preliminary Draft Best Available Control Technology (BACT)/Most Stringent Measure (MSM) Analysis for Stationary Sources in the affected area
- Preliminary Draft Best Available Control Measure (BACM) Analysis for sources in the affected area
- Preliminary Draft: “Residential Fuel Expenditure Assessment of a Transition to Ultra-Low Sulfur Heating Oil for the Fairbanks PM2.5 Serious Nonattainment Area”
The Environmental Protection Agency (EPA) reclassified the Fairbanks North Star Borough nonattainment area as a Serious Area with an effective date of June 9, 2017. Reclassification requires an update to the SIP to meet additional requirements that were triggered upon the reclassification. The preliminary draft documents are based upon information submitted to or obtained by ADEC to date. Some of the documents fulfill explicit EPA requirements for a Serious Area SIP while others are optional supporting materials.
ADEC is releasing preliminary drafts as an opportunity for additional data and information collection. Additional information that could assist in the finalization of the preliminary drafts is appreciated and may be incorporated into the final drafts. Individuals with additional information are encouraged to submit by sending to: firstname.lastname@example.org by May 23, 2018. Preliminary drafts are outside the formal public review process and therefore, there will be no formal responsiveness summary or hearing. Substantive information received may be included in the appendices, in final drafts, and cited where appropriate.
The following overview provides a brief summary of each of the documents, their importance to the Serious SIP, and initial approaches and concepts ADEC is considering.
Final drafts will be released as part of the formal public review process when the full Serious SIP is released later in 2018.
NOTE: DEC does not expect that all of the various ideas and measures presented will be part of the final plan, but it is important to open the dialogue with the full range of options. Also, there is no preliminary information completed yet on: economic analysis of control measures outside what is presented for #5 and #6a, emission benefits for control measures, modeling, or attainment scenarios.
- Draft Concept and Approaches
- Draft Baseline Emission Inventory
The Draft Baseline Emission Inventory preliminary document is the technical document that will ultimately reside in the SIP emission inventory appendix and will be used to update the SIP Emission Inventory chapter to meet the Serious Area requirements.
- Draft Technical Analysis Protocol
The Draft Technical Analysis Protocol (TAP) provides an overview and outline of the technical analyses required for the development of the Serious SIP. Included in the TAP are the methods used to the complete technical requirements as well as the identification of any unresolved issues. This is a living document that is updated over the course of the Serious SIP and there are a number of sections that are still in development.
- Draft Precursor Demonstrations
- Draft Best Available Control Technology (BACT) Analysis – Stationary Sources
Stationary sources that have a potential to emit over 70 tons per year (tpy) of either direct PM2.5 or a precursor must undergo a BACT analysis. This analysis identifies all the potential control technologies for each source based upon their specific types of equipment and determines a cost per ton and an efficiency rate. Based on the analysis, ADEC must determine what control strategies to require that are technologically and economically feasible for the area and still meet the intent of EPA requirements for BACT and Most Stringent Measure (MSM).
