Air Quality and Industrial Compliance
Sayreville, New Jersey
The facility is comprised of an electric arc furnace (EAF) that currently produces 85 tons of steel
billets per batch heat process, and a rolling mill that forms the reinforcing bars from billets.
Terranext has assisted this client with a range of environmental services, as highlighted below:
- PSD Permitting
Terranext is currently preparing a new PSD permit application to allow expanded production at this facility. The facility previously required assistance to proceed with a $40 million modernization project. Terranext was responsible for all aspects of the PSD permit application for the modernization, including BACT/SOTA and air quality impact modeling.
- CEMS Protocol
Terranext also prepared the CEMS protocol, wrote the CEMS specifications, reviewed CEMS proposals, selected the CEM vendor and assembled emissions information.
- Title V Permitting
Terranext prepared a Title V Operating Permit application for Gerdau Ameristeel's Sayreville mini-mill. The work included the development of an emissions inventory and determination of the emission rates each major emitting unit. State and Federal regulations that apply to facility operation are being reviewed and a compliance plan and Title V permit application are being developed.
- SPCC Plan
Terranext completed a Spill Prevention Control and Countermeasures Plan (SPCC). Work included identifying regulatory requirements, facility inspection for ASTs, preparing a tank location map, identifying SPCC team, determining role of team members, identifying reporting procedures, detailing response procedures and preparing the report.
- Mercury, Dioxin/HAPs BACT/SOTA
Terranext performed these additional BACT/SOTA analyses for the Melt Shop including cost effectiveness analysis of alternative approaches and associated balance of plant impacts, based on special request of State agency as a part of PSD permitting activities.
- Mill Optimization Plans
Terranext developed details and schedules for the Melt Shop process optimization program to reduce emissions and avoid triggering LAER requirements with a planned 50% mill production increase.
Project value is approximately $400,000 annually.
Air Quality and Industrial Compliance
Mount Sinai Hospital
New York, New York
Terranext is assisting this major metropolitan hospital in updating its air permits
and emissions information to comply with the latest New York State and Federal Clean Air Act
regulations under Title V. The facility operates six dual fuel-fired boilers to provide the
hospital with 125 psig steam. Four of the boilers are rated at 60,000 lbs./hr steam production
and two at 80,000 lbs./hr. Due to the size of the boilers, New York State regulations are requiring
stack testing to comply with NOx RACT rules. Terranext designed and supervised the stack testing
program and evaluated options (low NOx burners) for NOx control, as well as prepared emissions
information and recommendations for record keeping systems sufficient to address the New York State
permitting requirements. Terranext also prepared the Title V permit application and was responsibile for:
- NOx RACT Compliance Plan
- Boiler trouble-shooting
- Emission Source Identification
- Emissions Inventory/Quantification
- Regulatory Review
- Record Keeping/Reporting
- Compliance Plan Development
- Title V Application
Project value was $50,000.

Energy Engineering Audits - Multiple Sites
Texas, Ohio, New Jersey
Terranext performed comprehensive Energy audits and implemented Energy Management Programs at 10 different facilities for Owens-Corning. Project included establishing baseline utility usage, recommending a cost effective sub-metering and data collection program, developing an energy, water, and waste balance for each facility, and identifying key energy reduction projects. Project management software to measure actual energy usage/reduction and track energy projects was developed and launched at each facility. Project identified over $3 Million in potential costs savings in no cost and low cost projects. Project value was $190,000.
Energy and Water Resource Audit
Bunge Oil Plant
Terranext performed a comprehensive Energy and Water Resource audit at this Soya Bean oil plant for Bunge Chemical. Project included establishing baseline utility usage, recommending a cost effective sub-metering and data collection program, developing an energy, water, and waste balance for each facility, and identifying key energy reduction projects. Project management software to measure actual energy usage/reduction and track energy projects was developed and launched at each facility. Project identified over $500,000 in potential costs savings in no cost and low cost projects. Project value was $60,000.
Two of Shaw's carpet manufacturing plants were audited. Over $400,000 in annual energy bill savings were identified in various projects and operational changes in the 2002 audit. Over the next two years Terranext recommendations were implemented. Total energy savings for Shaw exceeded $400,000. Cost of the audits were $10,000.
