Design and construction roles with the Islip Resource Recovery Agency (IRRA) were turned into a consulting relationship lasting almost 20 years. In that time we maintained Macarthur, an IRRA plant on Long Island, eventually guiding upgrades that improved the efficiency and performance of the 454-metric-ton waste-to-energy facility.

» | Some components designed as equipment vendors were selected |
» | Rehab increased productivity where demand is high and space is scant for new facilities |
The relationship evolved when IRRA, faced with Clean Air Act compliance, asked us to prepare an assessment of Macarthur’s emission control systems that would define anticipated changes to the EPA's Clean Air Act. Regulatory changes were analyzed and existing technology assessed for its ability to meet air quality requirements. Using plant performance data, we identified modifications, wove in work schedules and costs, and navigated permitting in anticipation of the EPA's December 2005 compliance deadline.
Initial phases called for upgrading electrical capacity to power new equipment, and installing a new spray dryer absorber. A secondary air system was ordered to curb the plant's carbon monoxide emissions. Using specifications requested by IRRA, we were able to design spray dryer absorber fans before equipment vendors were selected.
Because of adequate planning, our regulatory experience and 18-year history with Macarthur, installations and upgrades were completed in two years and acceptance was issued by May 2005, more than six months ahead of deadlines. In complying with regulations and cutting acid-gas emissions in half, IRRA improved delivery of a renewable, strategic energy source and engendered consumer confidence by proving it was dedicated to environmental stewardship.
