Bureau of Police and Security

The Bureau of Police and Security is responsible for protecting the New York City water supply and the associated critical infrastructure from terrorism, pollution and crime.  In addition, the Bureau is also responsible for establishing on-site procedures intended to minimize the potential impact on human health and the environment in the event of a hazardous material incident.  To accomplish our mission, the Bureau is divided into four divisions, the Police Department which patrols the upstate water supply, the Security Division which employees private security guards for protecting in city facilities, the Security Systems Engineering Division which designs and implements security systems for the water supply system, and the Division of Emergency Response and Technical  Assessment (DERTA) which responds to hazardous material emergencies with in the city to evaluate the characteristics of the materials involved and make technical decisions concerning containment, abatement and disposal.  DERTA also oversees the Right To Know Program.

DEP Police

The primary mission of the DEP Police is to protect the water supply and the associated critical infrastructure from terrorism, pollution and crime. This is accomplished through the use of stationary posts, patrols, surveillance, investigation and technology. The DEP Police are all highly trained police officers with special skills and equipment geared to protecting the water supply. The patrol officers are augmented by an Emergency Service Unit, Aviation Unit, Detective Unit and Strategic Patrol Unit. The area of responsibility is the 2000 square-miles of upstate watershed and the associated critical infrastructure along with critical locations in the Bronx.

There are 7 DEP police precincts that serve as geographic base of operations to conduct day-to-day operations (e.g., walk-ins, daily patrols and other enforcement unit work), monitor electronic security systems and to dispatch forces as needed.

Five precincts are located in the West-of-Hudson (WOH) area and two precincts are located in the East-of-Hudson (EOH) area.

The West-of-Hudson (WOH) police precincts are located in Grahamsville, Ashokan, Gilboa, Beerston and Downsville, NY. The East-of-Hudson (EOH) police precincts are located in Eastview and Yonkers.

Security Division

The Division of Security manages the contract security of guard services at various DEP locations throughout New York. The Security Division is also responsible for monitoring the DEP Headquarters Access Control and Camera System and conducting security assessment of in city facilities.

Division of Emergency Response and Technical Assessment (DERTA)

The New York City Department of Environmental Protection Hazardous Material Response Unit is the oldest and most technically advanced HazMat unit in New York City. It emerged from DEP’s Bureau of Science and Technology in 1970s. It currently operates under the Division of Emergency Response and Technical Assessment (DERTA). The Division is made up of the Emergency Response Unit and Right To Know Program.

The DERTA Emergency Response Unit responds to in-city Hazardous Material incidents to undertake actions or establish on-site procedures intended to minimize the potential impact on human health and the environment. The Hazmat specialists, evaluate the characteristics of the materials involved and make technical decisions concerning containment, abatement, and disposal. They also determine the area extent of impact through on-site monitoring and computer models and determine the environmental impact of the incident.

The New York City Right To Know Law was passed by the New York City council in 1988. The intent of the law is to protect the environment, health and safety of community members, emergency response personnel, the general public and private/public property against exposure to hazardous substances as a result of fire, spill or accidental release, whether actual or threatened. Local Law No. 26 /Regulations requires facilities and local government agencies that use, store or otherwise handle any hazardous substances at or over certain Threshold Reportable Quantity (TRQ), to report the quantity and location within the facility where hazardous chemicals are present to NYC DEP.

DERTA is responsible for updating and maintaining a Web-based reporting system called the Tier II Filing System which allows facilities to electronically file their Annual, Revision or Update Facility Inventory Forms for each reportable substance they store, handle, use or process at their sites. They also review and evaluate Risk Management Plans for facilities storing extremely Hazardous Substances and inspect facilities subject to the Right to Know Program.

Division of Security System Engineering

The Division of Security Systems Engineering staffs engineers of varying disciplines
(i.e., chemical, civil electrical, project and construction managers) that are at the forefront of engineering technologies available for the protection of one of the world’s largest and effective water supply systems. The engineering staff review designs, provide comments on DEP projects with security as a focus, provide construction management for the constructions of facilities, as well as the installations of various security measures. They oversee the intergovernmental agreement that exists between DEP and the United States Army Corps of Engineers (USACE) for the design and installation of various security measures, such as electronic security and physical hardening. This Division also manages the maintenance contracts for all the physical, electronic and waterside security systems that have already been installed.
