General Permit for In Situ Remediation
Connecticut DEEP has developed general permits for the most common in situ remedial activities - enhanced aerobic biodegradation and chemical oxidation. In situ remedial activities not covered by a general permit may still be authorized through the issuance of an individual groundwater discharge permit or a temporary discharge authorization, as appropriate for the proposed activity.
DEEP Forecasts Elevated Levels of Ozone for June 4–5 2025
(HARTFORD) — The Connecticut Department of Energy and Environmental Protection (DEEP) is expecting temperatures to reach the mid-to-upper 80s (˚F) beginning June 4th, with high temperatures persisting and reaching near 90 on June 5th. These warm temperatures will contribute to elevated ozone levels for western Connecticut and inland areas on Wednesday and continuing from southwest Connecticut to northeast Connecticut on Thursday. These levels may approach or exceed Unhealthy for Sensitive Groups (USG) levels for these parts of Connecticut.

Siting Clean Energy on Brownfields
Renewable energy, such as wind and solar, can be sited on land that has been or is perceived to be polluted and is now underused. These properties, called brownfields, may be particularly attractive because these types of renewable energy installations may require large sites, and brownfields are usually large sites located in areas with the existing infrastructure needed to support development.
(HARTFORD)— As black bear activity increases in the spring following winter denning season, the Connecticut Department of Energy and Environmental Protection (DEEP) warns residents to be “bear aware” and to do what they can to protect both their communities and bears by preventing human-bear conflicts. Simple steps to avoid feeding bears such as taking down birdfeeders now that bears are up and about will reduce the likelihood of conflicts that can lead to potential harm for both people and bears.
