POINTS TO COVER
What is EPA’s Advance Program?
How the Air Quality Management Process works
The National Ambient Air Quality Standards
2008 Ozone Standard
PM 2.5 Standard
What does this mean to the Monroe Area?
Current Activities
Questions?
![Page 3: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/3.jpg)
WHAT IS THE ADVANCE PROGRAM?
Ozone Advance is a collaborative effort by EPA, states, tribes and local governments to encourage emission reductions in ozone attainment areas, to help them continue to meet the National Ambient Air Quality Standard (NAAQS).
Voluntary Program
![Page 4: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/4.jpg)
PROGRAM GOALS
Help attainment areas take action in order to keep ozone and PM levels below the level of the standard to ensure continued health protection
Better position areas to remain in attainment
Efficiently direct available resources toward actions to address ozone problems quickly.
![Page 5: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/5.jpg)
WHY SHOULD ATTAINMENT AREAS WORK TO REDUCE OZONE AND
PM2.5?
Ensure continued health protection Less resource intensive to implement measures early More flexibility to pursue a wide range of options Proactive
Could better position some areas to stay in attainment If eventually designated, could provide needed reductions
that could result in a lower classification and/or that could feed into any eventual SIP
EPA could consider early efforts as a factor in exercising for its discretion to redesignate areas not violating in 2008-10 but violating in later years to nonattainment
Multi-pollutant co-benefits

1990 - Clean Air Act Amended to its Present Form
There have been many iterations of federal clean air legislation, beginning in 1955.
![Page 8: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/8.jpg)
The Many Sources of Air Pollution
![Page 9: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/9.jpg)
NATIONAL AMBIENT AIR QUALITY STANDARDS
Developed for 6 air pollutants:
Sulfur Oxides Carbon Monoxide (CO) LeadParticulate (PM 2.5 & PM10) Ozone Nitrogen Dioxide (NOx)
States are required to develop plans to implement control strategies to make air healthier and cleaner.
Two types of standards Primary – protects public health Secondary – protects public welfare;
![Page 10: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/10.jpg)
GROUND-LEVEL OZONE IS:
The primary component of smog
Sometimes called “bad ozone” to distinguish it from “good ozone”
– Both types of ozone have the same chemical composition (O3).
–“Good ozone" occurs naturally in the upper portions of the earth’s atmosphere and forms a layer that protects life on earth from the sun's harmful rays.
- “Bad" ozone is harmful to breathe.
![Page 11: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/11.jpg)
GROUND-LEVEL OZONE
Ozone is not emitted directly into the air, but forms through reaction of nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight.
![Page 12: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/12.jpg)
SOURCES OF NOX AND VOCS
NOx forms quickly from combustion sources such as automobiles, power plants and large construction equipment.
VOCs come from paints, solvents and fuels and evaporate quickly into the atmosphere.
![Page 13: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/13.jpg)
WHAT IS THE 2008 OZONE STANDARD
Air quality across state continues to improve EPA expected to make standard more stringent Announcement December 2013 Imagine a limbo bar…
8-hour primary ozone standard to 75 parts per billion (ppb) is protective of human health 1 ppb is equivalent to 1 drop of water in an Olympic
sized pool How is attainment determined?
Design Value – the 3-year average of the fourth-highest daily maximum 8-hour average ozone concentration measured at each monitor within an area.
![Page 14: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/14.jpg)
DESIGNATIONS AND CLASSIFICATIONS
Designation refers to whether or not an area is above or below the standard Attainment means that the monitor readings
are at or below the standard;
Nonattainment means that the monitor readings are above the standard;
Unclassifiable means that there is no monitor data to reach a conclusion.
Classification categories are determined based on an area’s design value (applicable for ozone only).
![Page 15: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/15.jpg)
WHAT ARE MONITORS AND WHAT DO THEY TELL US?
![Page 16: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/16.jpg)
DATA SOURCES AND USES
Data from DEQ’s monitoring network is used to determine attainment with a standard
Modeling efforts
Industry reports emissions data (ERIC) which is used to develop strategies and rules to reach or maintain attainment
EPA uses ERIC-type data from every state to develop national strategies

POTENTIAL IMPACTS OF THE 2008 OZONE STANDARD ON NEW NONATTAINMENT PARISHES,
LOCAL GOVERNMENTS, INDUSTRIES AND BUSINESSES
Changed Emission Inventory Requirements
Lowered Major Source Thresholds
New Source Review
Emission Offsets
RACT Requirements
Potential for Automobile Inspection/Maintenance
Regulations on small businesses (bakeries, dry cleaners, paint shops, etc.)
Transportation Conformity/General Conformity
![Page 22: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/22.jpg)
POTENTIAL ECONOMIC IMPACT TO CONSUMERS
Increased cost to industry translates to increased cost of the products industry produces.
Higher cost of vehicle inspection stickers due to expansion of I/M program.
Increased fuel costs.
![Page 23: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/23.jpg)
TRANSPORTATION CONFORMITY
A special point on highway funding:
In nonattainment areas, the Clean Air Act requires a formal interagency process to establish procedures for consultation between MPOs, EPA, FHWA, FTA, and State and local transportation and air quality agencies.
Highway funding can be held up without this process in place. Transportation improvement plans must conform with air quality state implementation plans. (The SIP)

THANK YOU!
![Page 42: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/42.jpg)
QUESTIONS?
Do you know some of the most polluting equipment we use on a daily basis ?
Two-cycle gasoline powered string trimmers, chain saws and blowers are bad for both VOC and NOx emissions
About 30% of the fuel that you put into the tank for these items comes right back out unburned thru the exhaust.
![Page 43: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/43.jpg)
QUESTIONS?
Using your push lawnmower for an hour will produce how much pollution?
In an hour, a push mower will produce the same HC+NOx as a car driven 257 miles, and the same CO as one driven 401 miles.
To put it another way, assuming a car averages 40 miles per hour, a push mower produces more HC+NOx than six cars and the same CO as 10.
![Page 44: Air Quality NAAQS Update](https://reader036.fdocuments.net/reader036/viewer/2022062323/5681602a550346895dcf353f/html5/thumbnails/44.jpg)
QUESTIONS?
Which is worse for the environment: driving a massive, exhaust-belching diesel-sucking big rig 100 miles or walking down the street in hemp sandals, bamboo shorts and a reclaimed burlap poncho to a locally-owned restaurant, and ordering a grass-fed, locally-farmed angus beef hamburger?
For comparison, an 18-wheeler diesel engine truck would have to drive 143 miles on the freeway to put out the same mass of particulates as a single charbroiled hamburger patty.(UC Riverside)
