NHDES COVID-19 Program and Regulatory Updates

NHDES COVID-19 Message: We at the NH Department of Environmental Services (NHDES) pride ourselves on customer service in addition to our work protecting public health and the environment. The health and safety of our customers and staff is of the utmost importance, and as such, NHDES is working to slow the spread of the novel coronavirus by minimizing direct contact between our staff and the public. Please help us. If at all possible, do not come into our facilities. Instead, please call (NHDES main number is 603 271-3503) or email in advance so we can try to answer/resolve your questions remotely. Our contact info (and answers to many of your questions) can be found at In particular, the A to Z list in the upper right-hand corner of our homepage can help you quickly find the topic/pages you need. 

If you have documents to submit to the NHDES that cannot be mailed or emailed, they can be dropped off during normal business hours (weekdays 8 a.m.- 4 p.m.) in the designated drop-box located in the lobby at 29 Hazen Drive. We apologize for any inconvenience this may cause.

For New Hampshire-specific updates on COVID-19, visit or call 2-1-1.
