What a NYC Environmental Police Officer does

New York City Department of Environmental Protection / DCAS · Exam No. 6305 · facts last checked August 9, 2026

Environmental Police Officers protect the watershed areas, water supply systems and installations maintained by the New York City Department of Environmental Protection. They enforce the City's Watershed Rules and Regulations and other laws, and perform special duties as directed by superior officers. They operate motor vehicles and may perform aerial reconnaissance.

The phrase that best captures the job is in the notice's own Level I description: officers patrol and secure water supply facilities and lands, and monitor the environmental integrity of watershed areas. It is police work whose subject is a resource rather than a neighbourhood.

Patrol, order and arrest

At Assignment Level I, officers patrol the watershed area, reservoir areas, installations and other sites maintained by the Department for the purpose of safeguarding life and property. They maintain order by preventing breaches of the peace, despoilage and theft, and by arresting offenders.

The notice is specific about the standard for that last part: officers investigate suspicious persons and occurrences and make lawful arrests when probable cause exists. Probable cause is named, not implied, and it is the same standard that shapes the deductive-reasoning example on the ability list — deciding whether someone accused of trespassing should be arrested.

Officers also direct traffic as needed and may control access on Department grounds. The word "despoilage" in the duty list is worth noticing: this is a title where damaging the land is itself the offence being policed, not merely a byproduct of another crime.

Evidence, court and the paper trail

Officers collect evidence and consult with superior officers about preparing it for court presentation. They testify at trials and note the dispositions made of those cases by the court — a duty that runs past the verdict rather than ending at the courthouse door.

They submit reports on all unusual incidents, including accidents, occurring during their tour of duty, and investigate and report instances of contamination of watercourses or violation of the Watershed Rules and Regulations.

This is the concrete reason the exam tests written expression and written comprehension, and the notice's examples say so directly: written expression is illustrated by recording the details of an unusual incident, and written comprehension by reviewing an incident report. An account written on a fire road can be read back in a courtroom two years later, and the ability list is calibrated to that.

Assistance, education and reconnaissance

Officers may administer first aid where an accident occurs on their post, which is what the problem-sensitivity example on the ability list is drawn from — choosing an appropriate action for someone needing medical assistance.

They may also provide technical training and participate in public education programmes. That is a genuinely different duty from anything on the other uniformed notices covered here, and it reflects a watershed whose users are largely lawful visitors rather than offenders.

Aerial reconnaissance appears in the opening duty statement rather than in a specialist section, which suggests it is part of how the area is covered rather than an exceptional deployment. A watershed spanning ten counties is not patrolled entirely from a car.

Conditions: weather, distance and physical demands

The physical activities and environmental conditions the notice sets out are those of outdoor police work over long distances: working outdoors in all kinds of weather; walking or standing in an assigned area during a tour; driving or sitting in a patrol car during a tour while remaining alert; running after a fleeing suspect; climbing stairs; carrying an injured adult with assistance; gripping persons to prevent escape; restraining a suspect with handcuffs.

It also lists detecting odours such as those caused by smoke or gas leaks, engaging in hand-to-hand struggles to subdue a suspect resisting arrest, being physically active for prolonged periods, and carrying or wearing heavy equipment.

Two of the listed conditions describe the exam in physical form: understanding verbal communication over the radio with background noise, and reading and writing under low light conditions. A candidate who finds those two lines abstract has not yet pictured a report written at a reservoir gate in November at four in the afternoon.

Questions candidates ask

Do Environmental Police Officers make arrests?

Yes. The notice states that officers investigate suspicious persons and occurrences and make lawful arrests when probable cause exists, and that they maintain order by arresting offenders.

Are they real police officers?

They are sworn officers of the Department of Environmental Protection with arrest powers, who collect evidence, prepare it for court and testify at trials. The title, the exam and the jurisdiction are separate from the NYPD's.

What do they actually patrol?

Watershed areas, reservoir areas, water supply installations and other sites maintained by the Department, together with the surrounding lands and access roads.

Do they fly?

The notice states that Environmental Police Officers operate motor vehicles and may perform aerial reconnaissance. It does not describe what aircraft or how often.

Is there a public-facing side to the job?

Yes. Officers may provide technical training and participate in public education programmes, and most people met on watershed land are lawful recreational users.

How much writing does the job involve?

A great deal. Officers submit reports on all unusual incidents including accidents, report contamination and rule violations, prepare evidence for court presentation, and note case dispositions after testifying.
