MARAMA has conducted projects to better understand sources of air pollution and to assess the costs and benefits of emission control measures.
Refinery Emissions, Controls and Model Rules 2006-2007 assessment of control options and development of model rules. The project was in three phases: 1) Ranking of emissions, required controls, and the potential for additional emission reductions from refinery processes; 2) Identification of potential control measures for seven refinery processes and evaluated the cost and technical feasibility: 3) Development of state model rules for three processes: catalytic cracking units, equipment leaks, and flares.
- Assessment of Control Technology Options for Petroleum Refineries in the Mid-Atlantic Region
- Model Rule for Fluidized Catalytic Cracking Units
- Model Rule for Enhanced Monitoring of Equipment Leaks at Petroleum Refineries
- Model Rule for Petroleum Refinery Flares
- Summary of Stakeholder Comments
- Refinery VOC Emissions 2003 – Study to identify and recommend improvements to the regional refinery VOC inventory. Existing petroleum refinery emission inventories and estimation methodologies are summarized. Preferred emission estimation methods are identified for future inventory work. Finally, findings and recommendations are summarized to encourage both consistency among agencies and the use of more accurate methods.
- Reasonable Progress for Haze in MANE-VU-2007 analysis of sources and controls addressing numerous source types including Coal and oil-fired Electric Generating Units (EGUs).
- EGU Condensable Emissions – 2008 analysis of 162 regional stack tests to derive condensable emission factors for various EGU types.
- ERTAC Electric Generation Unit (EGU) Forecasting Tool
Residential wood combustion (RWC) means burning wood for heating, cooking, and aesthetic purposes both inside and outside the home. RWC emissions are a significant source of primary fine particle emissions in the MARAMA region however estimates are difficult, and some uncertainty always remains. MARAMA assists member agencies to improve their RWC estimates via ongoing coordination between agency and EPA staff and occasional targeted studies. Links to coordination and studies are provided here:
- Reasonable Progress for Haze in MANE-VU-2007 analysis of sources and controls addressing numerous source types including RWC and open burning.
- Open Burning in Residential Areas, Emissions Inventory Development Report – 2004
- Pechan 2002 RWC Survey and Regional Emissions Estimate
- Statistical Analysis of RWC Emissions
- How to Conduct a Survey of Residential Wood Combustion

Mobile sources are the largest source of NOX in the MARAMA region. MARAMA assists member agencies to improve their mobile estimates via ongoing coordination between agency and EPA staff and occasional targeted studies. MARAMA also provides coordination concerning mobile diesel emissions via a quarterly webinar series focused on diesel sources. Links to coordination and studies are provided here:
- MARAMA Mobile Workshop Events – MARAMA sponsors annual workshops for state agency staff to meet and compare notes on current topics for training and coordination.
- MARAMA Mid-Atlantic Diesel Webinar Series – As part of the Mid-Atlantic Diesel Collaborative (MDC)
MARAMA organizes a webinar series focused on diesel issues in the region.
- Targeted Studies Review of Mobile Source Emissions Inventories in the Mid-Atlantic Region-2000 – Analysis of mobile source emissions for eight major mid-Atlantic metropolitan areas for 1990 or 1996 comparing State and national emission inventory estimates and identifying assumptions underlying the calculations. Differences in calculation methodologies had a significant influence on highway vehicle emission levels. Estimating vehicle speeds by roadway type was the most important difference in emission rates by area.
