Area Sources & Fugitive Emissions
 Area refers to the source
 Fugitive refers to the emissions
 Also called non-point sources
 Quantifying emissions is difficult
 Controlling emissions is challenging

Particulate Matter (PM): Examples







Traffic on dirt roads
Tillage of cropland
Burning grasslands, pastures, crop stubble
Construction activities
Material conveyance, loading & unloading
Hard- and soft-rock surface mining
Rock crushing & handling
3
Burning of Grasslands,
Pastures, Crop Stubble
4
Rock Crushing Yard
5
Agriculture Operations
6
Fires
7
Dirt Roads

Methane Release
Guess what
I’m sorry
about
now…

Examples of Volatile Organic
Compounds (VOCs)
 Larger facilities (oil refineries, chemical
plants, manufacturing)
 Large lagoons, holding ponds (aerated)
 Tank farms
 Tanks & tank pressure-equalization vents
 Pipe seals, pumps, & valves
10
Pipe Flanges & Seals
11
Examples of Volatile Organic
Compounds (VOCs) [cont.]
 Communities
 Landfills
 Uncovered wastewater treatment
processes
 Sedimentation & aeration basins
 Trickling filters & bio-towers
 Residential wood combustion
12
Inefficient Wood Stove
13
Residential Aeration Basin
14
Examples of Volatile Organic
Compounds (VOCs) [cont.]
 Smaller facilities






Dry cleaners
Body & paint shops
Service stations & gas pumps
Office equipment (i.e., toner cartridges, etc.)
Small combustion devices (i.e., propane burners)
Any source using / storing solvents

Source “Control” and
Management
Controlling these sources is most practical by
targeted management actions of the activity
that creates the emissions
 Identify sources and data needs
 Quantify sources
 Evaluate impact on ambient air
quality
17
Management (cont.)
 Develop management options/practices
 Local / state / tribal regulations
 Implement control practices
 Evaluate effectiveness of control
practices
 Improve management “controls”
18
Identification, Quantification,
& Impact of the Problem
 Establish methodology
 How sources identified
 How emissions quantified
 Integrate information
 Regional or local AQ monitoring data
 Emissions inventory data
 Is there a problem? How big?
19
Develop Management
Options
Who has authority to regulate the source?
 Air quality agency
 Fire district
 Planning/zoning district
 City council
 Tribal authority
 Could be delegated to your environmental department!!
20
Develop Management
Options (cont.)
 Do avenues of control exist that are not
being enforced?
 What has been done in the past by
other groups?
 How effective have past practices been?
21
Implementation
 Develop program to implement chosen control
strategy





Public education
Permit program
Financial incentives
Codes, ordinances, laws
Source permitting
 Be sure program has flexibility to deal with
problems as they arise
22
Control Strategy: Examples
 PM
 Apply suppressant to heavily traveled roads
 Keep construction site damp
 Provide cover for material conveyance,
loading & unloading
 Install enclosure/shroud for rock
crushing/handing
 Dampen stock aggregate & sand piles
23
Control Strategy: Examples
(cont.)
 PM (cont.)
 Use wind breaks such as landscaping, fencing
 Encourage vegetation growth (re-vegetation)
 Install burlap or other porous, meshed
material
24
Driving at 15 mph
25
Driving at 25 mph
26
Oat Cover Crop
27
Control Strategy: Examples
(cont.)
 VOCs
 Repair & maintain pump & piping seals
 Cover or install recovery vents on open tanks
 Burning
 Restrictions on open burning & wood burning
 Certified wood stoves in new homes
 Cover wastewater treatment processes
 Business licenses require material balance information
28
Program Evaluation
 Develop procedure to evaluate effectiveness of
program
 Ambient air monitoring
 Cost analysis
 Tracking of response from regulated
community
 Documentation of progress—success & failures
 Develop new control strategies based on
program results
