Permitting and Emissions Regulations 25

• Permit forms—each agency has a standard set of forms they require permit
applicants to use. Many agencies have the forms available electronically as
downloadable documents that can be obtained from the agency Web site or
interactive online forms that feed directly into a database.
• Process description—a detailed process description that describes the opera-
tion of the facility in sufficient detail to support and confirm emission calcula-
tions and control strategies. Often process flow diagrams and process equip-
ment data sheets are provided.
• Emission estimates—the basis for each pollutant emission rate should be pre-
sented with supporting information such as emission test results from similar
units, vendor performance guarantees, or mass balance calculations.

• Control technology assessment—this may be a determination of the BACT or
LAER, depending on the attainment status of the region.
• Emission limitations—an assessment to be sure that statutory emission limita-
tions are achieved. Both federal and state emission limits should be identified.
• Air quality compliance—a dispersion modeling analysis may be necessary to
determine whether the NAAQS or the PSD increments are exceeded.
• Special issues—state and local agencies may request additional demonstra-
tions to show that hazardous air pollutants, noise, and odor are within accept-
able limits.
Permit review times will vary depending on the complexity of the permit appli-
cation. To ensure that the permit is reviewed in the shortest amount of time, it is best
to meet with the regulatory agency in advance, understand what information they
need to complete their review, and provide as complete a permit application as pos-
sible. A typical permit timeline is as follows:

• Determination of permit completeness—2 to 4 weeks,
• Technical review—4 to 12 weeks,
• Response to technical comments—2 to 8 weeks,
• Public comment period—4 to 8 weeks, and

• Issuance of draft permit conditions—2 to 4 weeks.
The above timeline does not include time spent preparing the initial permit
application.
