Colorado: An Air Quality History WESTAR SPRING BUSINESS MEETING MAR CH 29 – 30, 2010
Colorado by the NumbersColorado by the Numbers 5.17 million residents statewide (est.) 4.24 million residents in Front Range (est.) 54 “14ers” 29 Ski Areas GDP by Major Industry Sector (2007): Services – $65.7 Billion Finance, Insurance and Real Estate – $44.1 Government - $28.0 Information – $21.4 Manufacturing - $15.2 Retail Trade - $14.3 Wholesale Trade - $13.2 Construction - $12.4 Mining - $10.9
1970 Clean Air Act1970 Clean Air Act Most Sweeping Environmental Legislation in United States History Set National Health-Based Air Quality Standards Carbon Monoxide Lead Nitrogen Oxide Ozone Total Suspended Particulates Sulfur Dioxide Required States to Establish and Maintain Clean Air Required Each State to Adopt a State Implementation Plan and Establish Permitting and Enforcement Systems
NONATTAINMENT Denver-Metropolitan Area 4 of 6 Original Criteria Pollutant Standards (Carbon Monoxide, Lead, Nitrogen Oxide, Ozone) Also Nonattainment for PM10 Standard that replaced the TSP Standard in 1987 More Than a Dozen CO/PM10 Nonattainment Areas Throughout the State
Proactive Colorado (Firsts and Near-Firsts)Proactive Colorado (Firsts and Near-Firsts) 1977: Colorado Car (High Altitude Emissions Standards) 1981: Automobile Inspection and Maintenance Programs 1985: Emissions Standards for New Woodburning Stoves 1987: Mandatory Testing for Individual Diesel Vehicles and Fleets 1988: Oxygenated Fuels Program along Colorado’s Front Range 1990: Urban Visibility Standard 1990: Banned Sale of Non EPA-Certified Stoves 1993: Banned Installation of Woodburning Fireplaces in New Construction 1995: Enhanced Automobile Inspection and Maintenance
Colorado Air Quality TodayColorado Air Quality Today All Areas of Colorado Attaining Original National Ambient Air Quality Standards Working Effectively Toward Attainment of Newer, More Stringent Ozone Standard Expanding Air Quality Monitoring Network Expanding Air Quality Forecasting Statewide
Changing DemographicsChanging Demographics State Population Estimates 1970: 2,209,596* 1980: 2,889,733* 1990: 3,294,394* 2000: 4.33 million (2000 census) 2010: 5.17 million* 2020: 6.19 million* 2030: 7.23 million* Front Range Population Estimates * Colorado State Demography Office 2000: 3.54 (2000 census) 2010: 4.24 million* 2020: 5.01 million* 2030: 6.15 million*
Colorado Air Quality ChallengesColorado Air Quality Challenges More Stringent Standards Ozone 1997 Standard:.08 ppm 2008 Standard:.075 ppm 2010 (Proposed):.06 -.07 ppm Nitrogen Dioxide 1971 Standard:.053 ppm annual average 2010 Standard: 100 ppb (1-hour daily max) PM 2.5 1997 Standards: 65 μg/m 3 (24-hour avg.) and 15 μg/m 3 (annual) 2006 Standards: 35 μg/m 3 (24-hour avg.) and 15 μg/m 3 (annual)
Colorado Air Quality ChallengesColorado Air Quality Challenges Regional Haze Requires visibility improvements National Parks and Wilderness Areas Submitted BART for 12 Facilities in 2007 and 2008, plus other chapters Working on Reasonable Progress and BART Review with U.S. EPA (Region 8) in 2010 Mercury Over 18 Hg Fish Consumption Advisories in Colorado water bodies Statewide Regulations to Reduce EGU Mercury Emissions (2012, 2014, 2018)
Colorado Air Quality InitiativesColorado Air Quality Initiatives Proposed Clean Air/Clean Jobs Act Sharply reduce air pollutants by retiring, retrofitting or repowering Northern Front Range coal ‑ fired power plants by or before the end of 2017 (or sooner) Will help Colorado meet Regional Haze SIP Requirements Will help Colorado meet Ozone and NO2 requirements House Bill 10-1001 Requires 30 percent of electricity be generated by renewable sources by 2020 Requires 3 percent be met by solar power 100,000 solar rooftops Consumer and Rate-payer protections
