Robert Hodanbosi, Chief, DAPC Jennifer Dines, Manager, DAPC SIP Section Air Quality and SIP Update
National Ambient Air Quality Standards (NAAQS) • U.S. EPA has developed standards for six specific contaminants • Sulfur dioxide – primary source; coal fired power plants • Carbon monoxide – primary source: cars and trucks • Lead – primary source; individual industrial facilities • Nitrogen oxides – primary source; any type of combustion • Particulate matter – primary source; coal fired boilers, cement plants, steel making operations • Ozone – primary source; cars, trucks, utility boilers, painting operations, refineries
Air Quality Standard Process Typical • Clean Air Act requires standards to be reviewed • Clean Air Scientific Advisory Committee (CASAC) develops recommendations standards every 5 years • US EPA develops proposes/adopts standard • States have 1 Year to provide recommendations on “nonattainment” designations
Air Quality Standard Process Typical (Cont’d) • U.S. EPA has 1 year to finalize nonattainment designations • States have 3 years to submit plans/attain standards • Extra time is available if state is making “good faith” efforts • Litigation takes place and can disrupt the schedule
Ohio’s Attainment Status • The entire state is attainment for nitrogen dioxide, sulfur dioxide, and carbon monoxide. • Ohio has nonattainment areas for PM2.5, lead • Currently entire state is designated attainment for ozone and SO2 but this will change.
Revising Standards • U.S. EPA has been busy revising standards: • 2006: 24-hr PM2.5 • 2008: Lead • 2010: NO2, SO2 • 2008-2011: Ozone • 2011: CO • More to come: • 2012: PM2.5 • 2013-2014: Ozone NO2 SO2 Ozone PM2.5
Revised Standards …implementation will strain recourses
Progress Toward Attainment 0.125 ppm Standard – 1979 • Attainment - everywhere for many years 0.08 ppm Standard – 1997 • Met everywhere since 2008 0.075 ppm Standard – 2008 • Not being met in Cleveland, Cincinnati, and Columbus areas (2008-2010 data)
Ozone Standard: 2008-2011 Activity • On March 13, 2008, U. S. EPA announced a revised ozone standard of 0.075 ppm, average of the fourth highest concentration over a three year period • On September 16, 2009, U.S. EPA announced a review of the basis of the 0.075 ppm standard • On January 6, 2010, U.S. EPA proposed a new standard in the range of 0.060 to 0.070 ppm • On August 23, 2010, U.S. EPA announced a delay in the release of the new standard
Ozone Standard: 2008-2011 Activity • November 1, 2010, U.S. EPA announced another delay • On September 2, 2011 President Obama announced that U.S. EPA would delay going forward with new ozone standard until 2013, at earliest • On September 22, 2011 U.S. EPA announced they would move forward with implementing the 2008 standard
Ozone Standard: Implementing the 2008 Standard • Designations: • Proposal expected in December 2011 • Final designations expected by May 2012 • Expect the following areas will be designated nonattainment: • Cincinnati (79 ppb) -Butler, Warren, Clinton, Hamilton and Clermont counties • Cleveland (77 ppb) –Lorain, Cuyahoga, Lake, Geauga, Ashtabula, Medina, Summit, and Portage counties • Columbus (77 ppb) – Delaware, Franklin, Madison, Knox, Licking, and Fairfield counties
Ozone Standard: Implementing the 2008 Standard • Other SIP requirements: • Exact timing is to be determined • U.S. EPA expects a proposed implementation schedule in December 2011 • Historical (CAA) implementation schedule: • Attainment Demonstrations (3 years from designations) ~ May 2015 • Attainment Dates ~2015 to 2032 depending on severity
Ozone Standard: Implementing the 2008 Standard • U.S. EPA December 2011 proposal should also include classifications. • Based on historical classification methods, all three areas will likely be marginal nonattainment. Attainment would then be required three years from designations ~ May 2015 • There is a chance that U.S. EPA may tighten deadlines for attainment demonstrations and attainment.
Attaining the Standard: Major Components of Inventory ……it is not all about industry • Electric Generating Utilities • Other Industrial Point Sources (smaller industrial boilers and furnaces) • Area Sources (smaller commercial sources (dry cleaners, gas stations) and people (lawn mowers, residential heating, home painting)) • On-Road - Cars and trucks • Off-Road – Construction equipment, portable generators,farm equipment
Attaining the Standard: Applying the Model • Where the model indicates the standard will not be met, additional emission reductions need to be applied to the inventory – this reflects new control programs. • The model then is re-run until sufficient emission reductions are included to reach attainment.
Attaining the Standard: Identifying Control Measures • Ohio EPA first looks at multi-state control measures which U.S. EPA is implementing. • We examine control strategies which are required to be implemented by the Clean Air Act under the area’s classification.
Requirements for Ozone Areas - CAA Extreme Severe Serious Traffic controls during congested periods Clean fuels requirement for boilers (plan in 3 years) No waivers from 15% or 3% reduction requirements Requirement for fee on major sources if fail to attain Measures to offset VMT growth (108(f) measures) due in 2 yrs Contingency measures if miss milestone Specific NSR requirements for modifications to existing sources Moderate VMT demonstration due in 6 years (TCM program if needed) Clean fuel program due in 4 years (if applicable) Enhanced I/M due in 2 years Plan for 3% annual average reductions due in 4 years Marginal Demonstration of attainment in 4 years Basic I/M (if not already required) due immediately Stage II gasoline vapor recovery due in 2 years RACT: Existing & future CTG’s & RACT on major sources (existing due in 2 years) Plan for 15% VOC reduction within 6 years is due in 3 years New Source Review (NSR) program due 2 years (corrections to existing, also) RACT corrections due in 6 months; I/M corrections, immediately Emission inventory due in 2 yrs; requirements for emission statements due in 2 yrs; periodic inventories
What happens if the SIP is not approved? • US EPA is required to begin the “sanctions” process. • A sanctions letter is issued to the state that provides up to 18 months to fix problem • After 18 months, two for one offsets are required in nonattainment area • After 6 months, US EPA will stop federal highway money from going to the nonattainment area.
PM2.5 Air Quality Standard • Annual standard – 15 ug/m3, averaged over a three year period • 24-hour standard- 65 ug/m3 (old), 35 ug/m3 (newer) • Anticipate new review with possible revised standards in early 2012. Keeps getting delayed.
PM2.5 Annual Concentrations (ug/m3)Highest in Area Standard is 15.0 ug/m3
PM2.5 24-hour Concentrations (ug/m3)Highest in Area Standard is 35 ug/m3
Annual PM2.5 Attainment • All areas attaining based on 2007-2009 data. • Submitted Clean Data request on April 1, 2010. • But, no time to celebrate, EPA is making a health assessment review of annual standard – recommending between 11-13 ug/m3 with strong support for 11-12 ug/m3
Annual PM2.5 Redesignation Process • Preparing redesignation requests for all areas except Canton (*did not meet criteria) • Cincinnati-Hamilton area submitted in December 2010. U.S. EPA anticipates final action on the request in December 2011. • Columbus, Dayton-Springfield, Huntington-Ashland, Cleveland-Akron-Lorain submitted throughout 2011 and U.S. EPA is reviewing those. No proposals to date. • Ohio EPA continues to work on Steubenville-Weirton, Parkersburg-Marietta and Wheeling area requests along with WVA. Anticipate early 2012 submittals to U.S. EPA.
Attaining the 24-Hr PM2.5 Standard • Designations December 14, 2009. Only three areas designated nonattainment: • Cleveland-Akron • Canton (showed attainment but did not meet 75% capture) • Steubenville (due to WV monitor) • SIPs due December 2012 unless clean data requests are submitted. Likely will do. • Initial modeling shows only Cleveland will not meet the standard by 2015 with current controls. • Will likely use weight-of–evidence approach with on-the books controls.
Attaining the 24-Hr PM2.5 Standard: Cleveland • Local issue (“flats”): Seven county nonattainment area even though only 3 monitors in Cleveland have shown nonattainment. • PM2.5 RACT may be necessary.
Clean Air Interstate Rule (CAIR) • US EPA developed rules called Clean Air Interstate Rules (CAIR) to reduce emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2) from power plants in the eastern US • Helps reduce ozone and PM and reduces visibility impairment • Ohio has many coal-fired power plants and is a large emitter of NOx and SO2 • CAIR was going to require substantial emission reductions across eastern US and Ohio • CAIR remanded December 23, 2008
Clean Air Transport Rule (CATR) –proposedCross-State Air Pollution Rule (CSAPR) - final • July 6, 2010, U.S. EPA proposed a replacement to the CAIR program, the Transport Rule. • On July 6, 201, U.S. EPA finalized the replacement rule, the Cross-State Air Pollution Rule (CSAPR) • Will provide greater reductions than CAIR. • Necessitate year-round operation of existing SCR, SNCR and scrubbers. • Necessitate addition of pre-combustion NOx controls • Necessitate installation of new scrubbers for many sources. • Two phases: 2012 and 2014
Ohio EGU CSAPR Budgets vs Historical Emissions (tons) Budgets Historic **CSAPR will produce substantial emission reductions in Ohio
Lead Standard • Revised October 15, 2008 – from 1.5 ug/m3 to 0.15 ug/m3 as a rolling 3-year monthly average. • Two rounds – existing monitors and expanded monitoring network based on modeling potential violations from stationary sources. • Designations from first round were effective December 31, 2010. All areas are partial counties: • Fulton County – City of Delta area – Bunting Bearings Facility • Cuyahoga County – area surrounding Ferro Corporation • Logan County – south of City of Bellefontaine – Daido Facility (shutdown) • Four new monitoring sites added for second round…..so far no monitored violations at the new sites. • Designations from second round were effective November 8, 2011 – no new Ohio areas.
Lead Standard – Ferro “Situation” • Cleveland – has processes that use 98% lead (lead oxide) powder. • Highest three month average from 2005-2009 is 0.173 ug/m3. • 2010 and 2011 spikes as high as 2.57 ug/m3, • Looking at other potential sources located near the monitor (scrap yards, steel) • Investigating Ferro operations in detail. • Attainment demonstration due July 2012. • Attainment date ~January 2016
New Standard – NO2 • New standard effective April, 12, 2010. • The annual primary standard remains the same at 53 ppb • A 1-Hour standard is added: 100 ppb, which is met when the three year average of annual 98th percentile values are less than or equal to 100 ppb
Ohio Attaining new 1-hour…for now • Currently the only areas monitored in Ohio (Athens, Cincinnati and Cleveland) show attainment. • Highest 3-year averages between 2002 and 2009 are 66 ppb in Cincinnati and 72 ppb in Cleveland • Only county that currently fails is Cook Co., Illinois (Chicago), monitor next to bus stop. • Expanded monitoring network requires two types of monitors: • Area wide (community) where CBSAs > 1,000,000 • Near roadway where CBSAs > 500,000 • Monitoring plan due by July 2012 and network established by January 2013.
Monitors needed in Ohio • U.S. EPA is scaling back the regulatory monitoring requirements. • Will do phases starting with one area in Ohio - Columbus
NO2 Timeline • Ohio EPA submitted nonattainment recommendations based on current monitors by January 5, 2011 • All areas unclassifiable until new monitors in place • Final designations were issued by U.S. EPA on August 15, 2011 – no Ohio areas. • After other monitors are installed and three years of data collected (2013-2015), additional designations will occur. • Attainment demonstration due July 22, 2013 • Attainment date ~January 2017
NSR Issues • For permits issued by states with SIP-approved programs, permits issued on or after April 12, 2010 must contain compliance demonstration for 1-hour NO2 NAAQS • Although this effort appears to be mobile source driven, stationary sources are quickly being pulled in • Modeling shows emergency generators exceed standard • Two sources that emit only 7 lb/hr combined with 65 foot stacks, just meet standard
