Air Quality

Air Permitting

Environeer supports large and small organizations with air permitting by delivering innovative, cost-effective solutions that assure maximum efficiency.

Our air permitting services include:

Applicability Analysis
Emissions Quantification
Permit Application Development
Control Technology Evaluations

Permit by Rule (PBR)

PBR is allowed for facilities that will not make a significant contribution of air contaminants to the atmosphere if operated or constructed with certain restrictions.
PBR is used for activities that produce more than a de minimis level of emissions but less than required by other NSR permitting options. PBRs can be used to authorize emissions for changes to a facility or, sometimes, for an entire facility.
PBR authorization includes emissions quantification, control technology evaluations, air quality analyses (including dispersion modeling), emission standards applicability, and compliance assurance.

Standard Permit

Standard permit uses a streamlined permitting process to authorize specific, well characterized classes of facilities.
Standard permit can be used to authorize oil & gas handling and production facilities, pollution control projects, anhydrous ammonia storage and distribution, boilers, electric generating units, municipal solid waste landfills, permanent hot mix asphalt plants, concrete batch plants, etc.

New Source Review (NSR) Permit

NSR permit is required when emissions exceed what is allowed under PBR, or when a standard permit does not apply. Newly built or modified sources normally require an NSR permit.
NSR permit assures the following take place:
New/modified industrial sources operate as cleanly as possible.
Advances in pollution control grow simultaneously with industrial expansion.
When construction or modification at an existing facility adds a new source of air emissions, three NSR permitting requirements may apply and must be evaluated:
1. Prevention of Significant Deterioration (PSD) Permits
Required for new major sources or major sources that make a major modification in areas that meet the National Ambient Air Quality Standards (NAAQS).
2. Nonattainment NSR (NNSR) Permits
Required for new major sources or major sources making a major modification in areas that don't meet the NAAQS.
3. Minor Source Permits
Required for pollutants from stationary sources that don't require PSD or NNSR permits.

Title V Operating Permit

A federal 10-year permit that combines all existing air permit requirements.
A federally-enforceable document designed to improve compliance by clarifying air pollution control requirements.
Required for:
any major source that has actual/potential emissions = the major source threshold for any specific air pollutant.
any source with a PSD or NNSR permit.
affected sources under Acid Rain rules.
solid waste incineration units under Clean Air Act section 129.
certain non-major sources subject to NSPS/NESHAP/MACT/GACT requirements.

Air Compliance

Environeer assists organizations to develop & implement strategies to improve air compliance and avoid regulatory penalties.

Our compliance services include:

Compliance Reporting
Compliance Management Tools
Compliance Certification
Innovative Emissions Control Technology Evaluations
Emissions Trading

Emissions Inventory

Quantifying emissions allows annual reporting and determines fee payment to regulatory agencies.
Performing air dispersion modeling using emissions simulation software confirms compliance status and is vital for developing air compliance strategies.
Developing a comprehensive emissions tracking system and reporting methodology enables efficient management of emissions data.

NSPS & NESHAP Reporting

NSPS (40 CFR 60) are New Source Performance Standards, date-based, and apply to a facility based on the facility's construction, reconstruction, or modification date. The performance standards are based on industrial category (e.g., chemical plant) or source type (e.g., tanks, engines, boilers).
emissions standards are dependent on implementation cost, environmental impact, and energy requirements.
NESHAP (40 CFR 61 & 63) are National Emission Standards for Hazardous Air Pollutants (e.g. benzene, mercury, vinyl chloride, etc). The emission standards are pollutant-specific regulations and apply to both new and existing sources meeting specified applicability criteria.
pollutant-specific emission standards are technology-based and implement Maximum Achievable Control Technology (MACT) for major sources and Generally Available Control Technology (GACT) for area sources.

Emission Monitoring System Support

Some permitted facilities require specialized analytical equipment, known as a Continuous Emission Monitoring System (CEMS), to measure concentrations and/or emission rates of one or more smokestack pollutants. CEMS data is used to monitor air emissions compliance and is subject to regulatory agency review, and can trigger enforcement action where applicable.
Periodic stack testing involves taking emissions measurements, often in hourly intervals, or instantaneously, to determine compliance with permitted emissions. When used as an official compliance verification, a regulator is often present.
