Greenhouse Gas Rules Stakeholders Meeting10/18/2013

Page 2: Response to Comments on HAR Amendments

State GHG Requirements In 2007, Act 234 was

enacted. Act 234 required: 1) Statewide GHG limit set to

1990 levels. To be achieved by 2020.

2) DOH to adopt GHG rules to ensure GHG limit is met.

Background

Page 3: Response to Comments on HAR Amendments

Federal GHG Requirements In 2007, GHG emissions

became regulated. In 2009, Mandatory GHG

Reporting Rules. In 2010, Tailoring Rule

regulates GHG emissions under PSD and Title V.

In 2013, President’s Climate Action Plan directs EPA to issue GHG rules for power plants.

Background

Page 5: Response to Comments on HAR Amendments

Results of Comments Received GHG cap revised from 25% to 16%. Public participation for GHG

reduction plan approvals. Deadline for GHG reduction plans

extended to 12 months. Landfills with controls exempt from

GHG cap. No retroactive GHG fees. Revised definition of “subject to

regulation”

Scope of Authority Two separate sources of

authority:1) General powers under

342B-3, HRS and specific powers under 342b-12.

2) Subpart VI, 342B, HRS (Act 234).

Scope of Authority

Facility-Wide GHG Emissions Cap

A. Cap changed from 25% to 16%.

B. Alternate cap based on GHG Control Assessment.

C. Alternate Baseline Year.

Alternate Cap and GHG Control Assessment (B)

Facility must conduct a GHG control assessment.

Similar to BACT analysis. Director may approve an

alternate cap. Cap will be incorporated into

facility’s air permit.

Facility-wide GHG Cap

Page 14: Response to Comments on HAR Amendments

Alternate GHG Cap Baseline Year (C)

2010 is the default baseline year.

May propose an alternate baseline year

Methods to determine alternate baseline year are in HAR.

Public Participation.B. GHG Emission Reduction

GHG Emission Reduction Plan

Page 16: Response to Comments on HAR Amendments

Director’s Discretion and Public Participation (A)

Provisions for public participation are in HAR 11-60.1-205.

Provisions for contested case hearings are in HAR 11-60.1-206.

GHG Emission Reduction Plan Deadline (B)

Extended deadline to 12 months from the effective date of the rules.

Provisions for extending the deadline.

Proposed Control Strategy – Partnering

Partnering sources propose emissions above or below the facility-wide cap.

Each partner agrees to a revised emission level.

Revised GHG emissions cap placed in permit.

Each partner responsible for meeting its own cap.

MWC & MSW Landfill Exemptions MWC operations

1) MWC reduce waste going into landfills.2) GHGs from MWC have minor effect on

reduction levels.

MSW Landfills with controls

1) Landfill controls significantly reduce GHG emissions.

2) GHG from landfills with controls have minor effect on reduction levels.

MWC Operations and MSW Landfills

BACT Applicability Threshold State BACT threshold remains at 40,000 tpy

CO2e. State threshold is lower than 75,000 tpy CO2e

federal threshold. Lower state threshold will regulate emission

growth from new sources.

GHG Fees Draft rules were amended

to charge fees only after rules adoption.

Fees for GHG starts in 2015.

GHG Fees

Page 22: Response to Comments on HAR Amendments

Definition of “Subject to Regulation” Consistent with federal

definition Temporary exemption of

biogenic CO2 emissions removed.

Definition of Subject to Regulation

Page 23: Response to Comments on HAR Amendments

Where is Project Now? GHG Rules are being

circulated for approval DOH will send

notification to all commenters after rules are adopted.
