MACOM Environment & Energy offers a wide range of air quality services including air quality modeling, dispersion modeling, air pollution control system design, waste minimization, air quality monitoring, New Source Review permitting, compliance strategy development, emissions inventory development, and a number of other specialties within the air quality/air pollution control arena.  Our staff has extensive experience in performing air quality-related projects.

Air Permitting

MACOM Environment & Energy offer extensive experience and technical expertise in preparing air permit applications for numerous industries including chemical, pulp and paper, electric power generation, wood products and general manufacturing.  We provide air permitting services ranging from consultation and oversight to complex turn-key permit applications. We have developed permitting strategies for a wide variety of projects and typically work closely with our clients to develop applications and negotiate the most favorable permit conditions possible.

Our staff actively monitors regulatory changes and has a thorough understanding of the way permit applications are reviewed by regulatory agencies.

Our experience in air quality permitting includes:

• New source review permitting for non-attainment areas
• Permitting feasibility studies and sensitivity analyses
• Transportation facility applications and modeling analyses
• Control technology evaluations
• Emission estimates
• Emission netting analyses
• Air dispersion modeling
• Visibility impact assessments
• Ecological impact assessments

Air Quality Impact Evaluations

MACOM Environment & Energy offer a wide range of ambient air quality impact evaluations and dispersion modeling services. Generally, these evaluations are performed using dispersion modeling to determine the impact of source emissions on ambient air quality levels or to provide data for risk assessments. These analyses are usually a key aspect of regulatory air permitting decision-making. The following are some of the models that we use most frequently.

• AERMOD
• SCREEN3 Model
• ISCST3/LT3 Models
• CALPUFF Refined/Screening
• COMPLEX I Model
• CTDMPLUS Model
• RTDM Model
• VISCREEN2 Model
• PLUVUE II
• CAL3QHC2 (Transportation Model)
• PAL2 (Transportation Model)
• MOBILE5A (Emissions Model)
• Dispersion modeling

Compliance Services

Air permits and other air quality-related regulations often impose routine and non-routine compliance obligations with which the MACOM specializes.  In addition to such regulatory obligations, MACOM also provides a variety of compliance-related services designed to assist clients in determining compliance status and to streamline monitoring and reporting requirements to reduce compliance costs and potential liability.  Compliance-related services include:

• Annual air emissions inventories and Toxic Release Inventories (TRIs)
• Source measurements (“stack testing”)
• Continuous emissions monitoring design and programming
• On-site meteorological data processing
• Semi-annual progress reports
• Compliance audits
• Historical permitting reviews
• Database development/ management
• Monitoring protocols and strategies
• Combustion optimization

Air Quality Measurements for Process Optimization and Regulatory Compliance

 MACOM has been involved in a broad range of testing programs to establish emission rates of various air pollutants and to demonstrate compliance with different types of applicable emission standards and permit limitations.  Test programs include compliance testing for recovery boilers, evaluating emissions from burning alternative fuels in power boilers, evaluating process emissions for pollution reduction, screening hazardous air pollutant (HAP) emissions for control strategy decisions, and implementing Leak Detection and Repair (LDAR) programs.

Our experience with measurement programs allows MACOM to design a testing protocol specific to the needs of a facility.  MACOM has expertise in a variety of continuous measurement techniques capable of tracking emission levels and in integrated batch sampling methods for quantification of very low concentrations.  From our broad range of measurement options, we can provide the specific technology your facility requires for process optimization, demonstration of compliance, or pollution reduction strategy development.

MACOM Environment & Energy has Measurement capabilities for:

• Halogenated Compounds
• Hazardous Air Pollutants
• State-regulated Toxic Air Pollutants
• Metals
• Criteria Pollutants (e.g., NO_x, SO₂, PM)
• Nonhazardous Organic Compounds
• TRS
• NCASI Test Methods
