Environmental Programs: Frequently Asked Questions (FAQs)

Is my project/laboratory process regulated?

All process / equipment that use / store hazardous materials or discharge pollutants to the air, water or soil have the potential to be regulated. This includes, but is not limited to, all stationary combustion, large diesel trucks, greenhouse gas sources, tanks, construction activities, and any process or lab procedure that discharges hazardous materials to the air or sewer.

Does my new emergency generator/boiler/sterilizer require an air permit?

It depends on the size of the equipment. The following air sources require registration and/or a permit to operate:

Diesel emergency generators > 50 horse power

Boilers > 2 million Btu/hr (> 1 million Btu/hr if dual fuel)

Any source that releases Toxic Air Contaminants (TACs) in excess of the reporting thresholds

If you have questions regarding a new or existing air pollution source, contact Environmental Programs for a consultation.

How long will it take to get an air permit for a new source?

It depends on the size of the equipment. The following air sources require registration and/or a permit to operate:

• Diesel emergency generators > 50 horse power
• Boilers > 2 million Btu/hr (> 1 million Btu/hr if dual fuel)
• Any source that releases Toxic Air Contaminants (TACs) in excess of the reporting thresholds

If you have questions regarding a new or existing air pollution source, contact Environmental Programs for a consultation.

Can I buy a new large truck from Nevada and use it in the UCSF fleet?

Diesel engines are regulated by the BAAQMD for particulate matter. It is not likely that a diesel registered in Nevada will meet current emissions standards in California. In addition, it is illegal to sell a non-compliant diesel engine within the borders of California. Please contact Environmental Programs prior to the purchase of any large diesel powered trucks or equipment.

What is an occupancy rating/chemical load analysis and how do I get one?

All buildings have an occupancy rating that, among other things, dictates the total chemical volumes allowed within the building. Occupancy ratings are dictated by the California Fire Code. All construction projects or major changes in room usage may initiate a chemical load analysis. Aggregate chemical volumes within a control area are compared to the limits established by the California Fire Code and sent to the State Fire Marshal for approval.

Environmental Programs provides chemical loading analysis using the online chemical inventory system for both internal and external project management. Refer to the chemical inventory section on the Environmental programs site or contact Environmental Programs for more information.
