The Fort Hamilton environmental program strives to attain and maintain optimum performance in regulatory compliance; prevention of releases of hazardous substances; and assessing actions for adverse environmental effects in order to enhance human health, safety, and well-being while strengthening the Army ability to perform at its maximum capability.

Pesticides: Fort Hamilton has an active Pest Management Plan that protects real property and the health of soldiers, civilians, and family members from pests through use of integrated pest management (IPM) strategies; reduces the use of chemical pesticides; and reduces environmental risks from pesticides through proper storage, handling, application, and disposal of pesticides.

Pollution Prevention (P2) is a comprehensive initiative to reduce and prevent pollution at the source. It focuses on conservation of resources, replacement of hazardous materials with less hazardous materials, waste reduction, recycling, and other preventive means to successfully and cont effectively avoid, prevent or reduce the generation of pollutants.

Storm-water Pollution Prevention: Storm-water is rain and snow that runs off surfaces such as rooftops, paved streets, and parking lots. Storm-water can carry harmful pollutants to our most precious resource, water.

Cultural Resources: It is Fort Hamilton policy to ensure that informed decisions are made regarding our cultural resources, in compliance with public laws, in support of our mission, and consistent with sound principles of cultural resources management. Our goal, implemented through the Integrated Cultural Resources Management, is to develop and implement procedures to protect against encumbrances to mission by ensuring that we effectively manage cultural resources. Three of the installation's structures are listed on the National Register of Historic Places (NRHP): (1) Building 207; (2) Building 220; and (3) Building 230. Denyse Wharf and two other structures have been determined eligible for listing on the NRHP: (1) Building 113 and (2) Building 201.

The presence of prehistoric sites within the fort has not been verified. The contact-period Native American village of Nayack is reported to have been within the fort in addition to other undocumented prehistoric or contact period sites. These include: (1) a cache of stone or flint blades, (2) a shell bed, and (3) "traces of occupation." These sites have not been encountered by previous archaeological inventories, possibly due to the amount and depth of fill at the fort.

Natural Resources: Canada geese are found at US Army Garrison Fort Hamilton. According to the New York State Department of Environmental Conservation Division of Fish, Wildlife and Marine Resources, the Canada geese are a valuable natural resource. All Canada geese are protected by Federal and State laws and regulations.

Other programs under the Environmental Division are: Hazardous Waste, Universal Waste, HAZCOM, Installation Restoration, Noise, Spill Prevention, Storage Tanks, Solid Waste, Air Emissions, Drinking Water, and Solid Waste.
The Environmental Division keeps up to date on all environmental regulations, environmental requirements, and environmental best practices to ensure that Fort Hamilton is kept in environmental compliance. Including the Environmental Division in all garrison activities that could potentially cause a threat to the environment ensures that those threats are mitigated.
