VERMONT
DE MINIMIS EXEMPTIONS:
Any generator that is rated at less than 450 bhp-hr and is located at a facility with no other air contaminant
sources does not require a permit. However, if a generator sells electricity back to the grid the state requires
a permit. Also, if there is clear intent to circumvent permitting requirements by installing multiple small
generators that have a total rating greater than 450 bhp-hr, the state requires a permit. The state does not exempt
any modifications to existing units from permitting.
MINOR SOURCE PERMITTING:
If the unit is less than 450 hp and it must be permitted it will be required to meet a 20% opacity requirement,
a PM limit of 0.5 lb/MMBtu and sulfur content in diesel oil must be less than 2%. Sources that are larger than
450 hp must also meet the following requirements:
6.9 g/hp-hr or 505 ppm for NOx
3.0 g/hp-hr or 360 ppm for CO
0.45 g/hp-hr or 0.063 g/cubic meter for PM-10.
Units must either stack test or meet off-road certification requirements to show compliance.
There is no comment period if the source has a potential to emit less than 10 tons per year of all criteria
pollutants. Larger sources have a 30 day public comment period. The entire permitting process for units with a
potential to emit less than 10 tons per year takes about 30 days, there is no upper time limit for larger sources.
The state official contacted was working on a permit that was applied for 5 years prior.
MAJOR NSR/PSD PERMITTING:
A potential to emit 250 tons per year of a criteria pollutant triggers PSD. *See "Special Consideration"
below.
TREATMENT OF EMERGENCY ENGINES:
Any emergency diesel generator that is rated above 450 bhp-hr and is located at a facility with no other air
contaminant sources does not require a permit provided that the generator operates 200 hours or less per year.
Special Consideration:
The state has a more stringent permitting program for major sources than the federal PSD/NSR program. In Vermont
the major source threshold is triggered when a source has the potential to emit 50 tons or more of a criteria pollutant.
These sources must meet a standard called, "most stringent emission rate" or MSER. State officials describe
this requirement as LAER with some consideration given to cost.
All potential electric power generating facilities must file a petition with the Vermont Public Service Board
pursuant to
Vermont Statutes Annotated Title 30 Section 248. The statute explicitly exempts self-generators
that do not sell any excess power. In addition to obtaining approval from the Vermont Public Service Board,
there may be other local, state, and federal approvals also required. The process before the Vermont Public
Service Board is a contested case process. It involves technical hearings at which interested parties are
permitted to intervene. The Vermont Department of Public Service is a statutory party and represents the
rate payers and the public interest.
