Representative Projects:
Semiconductor Manufacturing Company - Emissions Control Program
Business Objective
A large aerospace and electronics manufacturing company was required to reduce its emissions
of volatile organic compounds (VOCs) from its semiconductor operations at
five separate facilities; ALG staff was contracted to develop and implement
a control program, within a compressed schedule under an enforcement action
brought by a local air pollution control agency.
Technical Approach
The initial engineering analysis revealed that traditional VOC control technologies (thermal, catalytic, and
regenerative systems) and adsorption techniques were either ineffective,
or very expensive (upwards of $65,000/ton of VOC controlled). ALG staff
identified an innovative control technology UV ozonation and,
together with the client and the local agency, implemented a demonstration
program. The innovative technology was shown to achieve control
requirements at a substantial reduction in overall control costs. Working
with the client, ALG staff also identified process modifications and solvent
substitutes for application at selected facilities.
Results
The innovative control technology, coupled with process modifications,
were successful in achieving a 90% reduction in VOC emissions at an
estimated annual savings of $3,000,000 to the client over the traditional
VOC control technologies. Controls were installed within the schedule
required by the local agency.
Plastic Extrusion Company - Environmental Compliance Program
Business Objective
A plastics manufacturing facility initially sought ALG's emission engineering and compliance assistance to prepare
annual toxic inventory release information as required by the Emergency
Planning and Community Right to-know Act (EPCRA). During the course of the
project, ALG identified additional potential compliance issues relative to
federal, state, and local air, water, and waste regulations.
Technical Approach
At the request of the client, ALG performed a complete environmental audit
relative to applicable environmental requirements and determine any
potential liabilities. The audit revealed several compliance issues,
including air permitting requirements associated with essential production
equipment.
Results
Within 30 days of the audit, ALG prepared all necessary applications
required to comply with air quality control regulations, including air toxic
health risk assessments and ambient air quality dispersion analyses.
Together with the client, ALG was successful in negotiating local agency
permit approval within three weeks of application submittal. ALG continues
to work with client's staff, and has provided ongoing environmental support
to ensure compliance of our client's operations with the Clean Air Act,
Clean Water Act and the Resource Conservation and Recovery Act.
Petroleum Refinery - Title V Compliance Program
Business Objective
ALG was contracted by a major West Coast refinery to prepare and execute its Title V Compliance Program.
Technical Approach
Working with the refinery's legal counsel, environmental and engineering staff, ALG
designed a phased program to:
- Identify all applicable requirements under the federal and state air pollution control laws and regulations;
- Audit the facility to assure compliance with these obligations;
- Define and execute a remedial plan to correct any deficiencies noted during the audit; and
- Prepare the permit application.
During the project, it became clear that the Title V application forms required by the local air agency would be unduly
burdensome when applied to the facility. ALG therefore negotiated a
streamlined application form for use by the refinery, thereby substantially
reducing the level of effort required to develop the application.
Through negotiations with agency staff, ALG also used the Title V permitting
process to greatly reduce ongoing recordkeeping, monitoring and reporting
requirements that would otherwise apply to the refinery.
Results
Through these negotiations and additional permit hygiene measures, ALG
reduced the potential enforcement exposure to the refinery. The final permit
application reflected the maximum operational flexibility allowed under the
Federal Title V program and local permitting regulations.
