Business/Industry FAQs


Public/Homeowner FAQ

Question: I’m interested in starting a business in Delaware.  How do I find out what environmental permits I’ll need?
If you are starting a small business, contact DNREC’s Small Business Ombudsman Michelle Jacobs at (302) 739-9069. DNREC also has a Regulatory Advisory Service that can help you identify all of the requirements for your business. For a description of all the Division of Air Quality regulatory programs, click Regulatory Programs.

Question: How are air permitting decisions made?
Answer: DAQ has a four-step process. First, DAQ determines if a permit is even needed. The criteria are emissions of more than 10 pounds per day of air pollutants before going through control devices, or 10 pounds per day from all equipment after going through control devices. Second, the Division determines what type of permit is required. DAQ issues five types of permits and which one depends on whether it is for construction or operation, the amount of pollutants to be emitted, and the type of pollutants to be emitted. Third, the Division determines what requirements to include in the permit. These requirements are based on DNREC regulations and federal rules. Finally, DAQ will determine if there are any additional requirements specific to the equipment or process based on the environmental history of the facility and public comments received as a result of a public notice, a public workshop or a hearing.
