Overview of Air Quality Issues in Tennessee :  Overview of Air Quality Issues in Tennessee TCC&I/UT-CIS Complying With Air Quality Regulations Workshop Knoxville, Tennessee June19, 2007 Presentation Outline:  Presentation Outline 8-hour ozone SIP PM2.5 SIP Regional Haze SIP Atmospheric Mercury Deposition 8-Hour Ozone Attainment Status :  8-Hour Ozone Attainment Status White Counties are attainment Yellow Counties are nonattainment - deferred effective date (EAC) Red Counties are nonattainment 8-Hour Ozone Attainment Status:  8-Hour Ozone Attainment Status EAC Counties (yellow on map) are predicted to attain by 12/31/07 and must measure attainment by that date (2005-2007 data). Nonattainment counties (red on map) Greater Knoxville Area measures attainment based on the 2004-2006 data Redesignation to attainment petition has been filed with EPA – awaiting decision Shelby County was to have attained (2004-2006 data) by 06/15/07 and did not Will likely be “bumped up” to a Subpart II Moderate Area Statutory control measures for Subpart II Moderate Areas Big News Tomorrow Stay Tuned:  Big News Tomorrow Stay Tuned The New Ozone NAAQS Will Be Proposed Tomorrow, June 20, 2007 How Low Can You Go? 2007 Ozone Preliminary Data:  2007 Ozone Preliminary Data PM2.5 Attainment Status:  PM2.5 Attainment Status Slide9:  Preliminary 2004-2006 PM 2.5 Data Evaluation (Data extracted 04/19/2007 from AIRS AQS. Evaluation date 05/07/2007.) TEOM PM2.5 2007 Data – Not Federal Reference Method Data:  TEOM PM2.5 2007 Data – Not Federal Reference Method Data PM2.5 Control Measures Likely Driven By Sulfur and Organic Carbon Reductions:  PM2.5 Control Measures Likely Driven By Sulfur and Organic Carbon Reductions Tennessee PM2.5 Control Measures:  Tennessee PM2.5 Control Measures Stage I Vapor Recovery applied in several counties for 8-hour ozone – helps reduce organic carbon for PM2.5 Fuel Sulfur Restrictions are being considered to minimize sulfate formation as needed for the “reasonable progress” regional haze reviews and as needed for the PM2.5 SIP “Hazed & Confused?”:  “Hazed & Confused?” Best Available Retrofit Technology (BART):  Best Available Retrofit Technology (BART) Exemption modeling performed by VISTAS contractor for six sources DuPont White Pigment and Mineral Products (Humphreys County) E.I. DuPont de Nemours & Company, Inc. (Shelby County) Lucite International, Inc. (Shelby County) Owens Corning (Madison County) PCS Nitrogen (Shelby County) Zinifex (Montgomery County) All six sources modeled impact <0.5 dV Modeling report submitted to EPA and FLM Favorable comments received from EPA, comments not yet received from FLM Best Available Retrofit Technology (BART):  Best Available Retrofit Technology (BART) Exemption modeling received from two additional sources TVA Bull Run Fossil Plant (Anderson County) Packaging Corporation of America (Hardin County) Both sources modeled impact <0.5 dV Modeling reports submitted to EPA and FLM Favorable comments received from EPA and FLM for PCA Favorable comments received from EPA for TVA, comments not yet received from FLM Still expect to receive modeling from TVA Cumberland Fossil Plant (Stewart County) Best Available Retrofit Technology (BART):  Best Available Retrofit Technology (BART) BART determinations submitted to the Division by three facilities Eastman Chemical Company (Sullivan County) Alcoa (Blount County) E.I. DuPont de Nemours & Company, Inc. (Davidson County) Eastman and Alcoa determinations have been submitted to EPA and FLM for review DuPont submittal currently being revised Reasonable Progress Analysis:  Reasonable Progress Analysis Considered pollutant contributions from 2000 – 2004 for 20% best and 20% worst days Calculated natural background conditions and developed a glide path Performed emissions sensitivities Developed Area of Influence (AOI) Back trajectory and residence time analysis Source sector emissions List of contributing sources Slide20:  New IMPROVE equation Uniform Rate of Progress Glide Path (Base G2a projections) Great Smoky Mountains - 20% Worst Days 30.28 29.01 25.85 22.69 19.53 16.37 13.20 11.31 22.87 0 5 10 15 20 25 30 35 2000 2004 2008 2012 2016 2020 2024 2028 2032 2036 2040 2044 2048 2052 2056 2060 2064 Year Haziness Index (Deciviews) Glide Path Natural Condition (Worst Days) Observation Method 1 Prediction Uniform rate of progress = 4.4 dv by 2018 Slide22:  Residence Time for 20% Worst Days in 2000-2004 Great Smoky Mountains, TN Slide23:  SO2 Area of Influence for Great Smoky Mountains Green circles indicate 100-km and 200-km radii from Class I area. Red line perimeter indicate Area of Influence with Residence Time > 10% Orange line perimeter indicate Area of Influence with Residence Time > 5%. Slide24:  2018 SO2 Emissions weighted by Residence Time Great Smoky Mountains, TN Green circles indicate 100-km and 200-km radii from Class I area. Red line perimeter indicate Area of Influence with Residence Time > 10%. Orange line perimeter indicate Area of Influence with Residence Time > 5%. Slide25:  Annual 2018 BaseG2 Emissions (%) Within Area of Influence Great Smoky Mountains, TN Slide26:  Annual 2018 BaseG2 Emissions (%) Within Area of Influence Great Smoky Mountains, TN Reasonable Progress Analysis:  Reasonable Progress Analysis VISTAS contractor provided list of all facilities located within Area of Influence (AOI) Review list, consider sources that contribute greater than 1% Contribution based on magnitude of emissions, distance, and maximum residence time Reasonable Progress Analysis:  Reasonable Progress Analysis Required by Regional Haze Rule [§51.308(d)(1)(i)(A)] to consider four factors when establishing our Reasonable Progress Goal (RPG) Cost of compliance Time necessary for compliance Energy and non-air quality environmental impacts of compliance Remaining useful life of any existing source subject to the requirements Reasonable Progress Analysis:  Reasonable Progress Analysis State will conduct analysis of four factors using source-specific information provided by facilities and general industry-specific information. And then there are Class I Areas Outside of the VISTAS RPO - This one from MO & AR:  And then there are Class I Areas Outside of the VISTAS RPO - This one from MO & AR Regional Haze SIP Submittal Timeline:  Regional Haze SIP Submittal Timeline June 12 – 13, 2007 – Face-to-face consultation meeting with EPA and FLM July 2007 – Reserved for consultation as needed with other RPOs August 1, 2007 – Submit SIP proposal to FLM to begin 60 day consultation period September 2007 – Public Notice for review of the SIP October 2007 – Hold Public Hearing for the SIP November 2007 – Present SIP to Air Pollution Control Board December 17, 2007 – Submit SIP to EPA 8-Hour Ozone Regional Haze & PM2.5 SIP Summary::  8-Hour Ozone Regional Haze & PM2.5 SIP Summary: SIPs are approved for the three EACs Knoxville has a redesignation request – if not approved by 6/15/07, a findings clock will start to submit a SIP for the area Memphis will have a SIP due date later than 6/15/07 as part of the likely “bump-up” Continuing work on BART, Reasonable Progress, and entire Regional Haze SIP package – due December 17, 2007 PM2.5 modeling is complete, working on SIP submittal package – due April 5, 2008 Mercury From Coal Fired Boilers:  Mercury From Coal Fired Boilers Tennessee adopted the EPA CAMR Rationale: EPA CAMR preamble said it would solve the national issue of mercury No known “hot spots” of mercury deposition in Tennessee Tennessee power plants will be controlled with SCR/FGD pairings to the extent that the state will be an “exporter” of mercury credits Mercury From Coal Fired Boilers:  Mercury From Coal Fired Boilers Environmental groups and elected officials are calling for Tennessee to be more stringent than CAMR An extensive mercury deposition study designed by national experts will be conducted if funding is provided. Dr. Jerry Keeler and Dr. Jim Wiener preparing the study plan Plan will be presented to the federal government requesting funding Mercury From Coal Fired Boilers:  Mercury From Coal Fired Boilers Plan is likely to be expensive If the study reveals that Tennessee should be more stringent than CAMR, the information will be taken to the state air board for consideration.
