2Energy Projects
- Pyrolysis
- Methane Digesters (Biogas Processing)
- Gasification
- Waste Combustion (Poultry Litter)
3Air Emissions
- Alternate energy fuels may actually result in
higher emissions of some pollutants than use of
conventional fuels. - Emissions from Waste Energy Projects may be
sufficient to trigger DEQ New Source Review (NSR)
Permitting. -
4Associated Air Pollutant Emissions
- Nitrogen Oxides
- Sulfur Oxides
- Particulate Matter
- Carbon Monoxide
- Volatile Organic Compounds
- Hydrogen Chloride
- Cadmium
- Mercury
- Lead
- Trace amounts of other Hazardous Air Pollutants

7Air Quality Impacts
- Ozone Formation
- Regional Haze
- Nutrient Deposition
- Stream Acidification
- Odor
8Odor
- Most of these Waste Energy Projects can create
odor nuisances. Pollution from animal waste can
cause respiratory problems, skin infections,
nausea, and other illnesses for people living
near these operations.
9Odor Regulation
- Virginias Regulates Odor
- Virginia Air Regulation (Rule 4-2) states no
owner or other person shall cause or permit to be
discharged into the atmosphere from any affected
facility emissions which cause an odor
objectionable to individuals of ordinary
sensibility. - Upon determination that an odor violates Rule 4-2
the owner shall use such measures as approved by
the board for the economically and
technologically feasible control of odorous
emissions.
10Regulatory Considerations
- Air Permitting
- All projects should be reviewed for applicability
under the New Source Review (NSR) permit programs
(pre-construction review) - Individual permit program
- Requires application of Best Available Control
Technology (BACT) - Air Quality Demonstration
- Federal standards may apply
11Objectives of the Minor Source NSR Permit Program
- Assure that emissions increases from new projects
protect air quality - Mitigate the impact of emissions increases
through the application of air pollution control
practices/ technologies
12Waste Energy Projects that may be subject to NSR
permitting include
- Construction or relocation of a new
stationary source at an undeveloped site - Modification or reconstruction of a
stationary source at an existing site - Includes adding a new emissions unit at an
existing source
13Permit conditions may include
- Emissions limitations (lb/hr ton/yr)
- Fuel type and throughput limitations
- Other operational restrictions
- Control device requirements (if applicable)
- Monitoring, recordkeeping and reporting
- Notification requirements
- Stack testing (as appropriate)
- Other performance tests
14Emission Control Requirements
- Add-on controls for control of particulate,
sulfur dioxide, nitrogen oxides, odor - Enclosure/containment requirements for raw
material/ash storage areas - Fugitive dust control
15Air Permit Threshold Emission RatesMinor Source
(NSR)
- Carbon Monoxide 100 tons per year (tpy)
- Nitrogen Oxides 40 tpy
- Sulfur Dioxide 40 tpy
- Particulate Matter 25 tpy
- Particulate Matter (PM10) 10 tpy
- Volatile Organic Compounds 25 tpy
- Lead 0.6 tpy
- Hydrogen Sulfide 9 tpy
16Determination that a NSR Permit is Required
- Permits need to be issued prior to the
commencement of on-site construction activities
of the emissions unit - Construction activities include the installation
of equipment supports and foundations,
underground piping/conduits
17Air Compliance
- Beginning construction or operation of any
facility requiring an air permit to construct and
operate is a violation of the Virginia Air
Regulations and subject to enforcement by DEQ
18To Request a Permit Determination
- Download the state application Form 7
- http//www.deq.virginia.gov/air/justforms.html
- Complete the relevant pages of the form for your
particular project - Example Pages 1-3, 4, 11, 14, 17 and 18 for
boilers, IC engines, turbines -
- Submit the completed and signed form to the
appropriate DEQ regional office - http//www.deq.virginia.gov/regions/homepage.htm
-
19Basic information is needed to complete the Form 7
- General information (Pgs 1-3)
- Facility name, contact information, mailing
address, project dates - Information on the fuel-burning equipment (Pg 4)
- max. rated heat input capacity
- max. rated output (steam quantity, brake HP or
electrical power - Fuel types to be used
- Stack and fuels data (Pg 11)
- Proposed emissions rates (Pgs 14 and 17)
- Operating periods (Pg 18)
20Emissions Estimate for the Form 7
