DEC regulates pesticides and handles compliance assistance, public outreach activities, and enforcement of the requirements in the Environmental Conservation Law (ECL).

Hot Topics:

Glyphosate Stakeholder Meeting

A recent amendment to the Environmental Conservation Law bans any state department, state agency, public benefit corporation or any pesticide applicator employed as a contractor or subcontractor to apply glyphosate on state property. However, there are exemptions to this ban to maintain critical infrastructure, manage roadside vegetation to ensure public safety, for the control of invasive species and pests of significant public health importance, and for research purposes. The law is effective December 31, 2021. The text of the law can be found on the NYS Senate page (leaves DEC website).

The DEC will hold a stakeholder webinar on October 27, 2021 from 1-3 PM concerning the pesticide regulations to implement this law. Stakeholders are invited to the webinar to hear about potential revisions, express views, and provide input in developing regulations. Registration for the webinar is required.

Chlorpyrifos Pesticide Registration Cancellations and Proposed Regulation

July 21, 2021 - DEC announced a regulatory revision to 6 NYCRR Part 326 to prohibit the sale, distribution, possession, and use of pesticide products containing the active ingredient chlorpyrifos. This regulatory revision was effective July 31, 2021.

December 31, 2020 the New York State pesticide registrations were cancelled for 29 pesticide products containing chlorpyrifos and on July 31, 2021 the remaining fifteen pesticide products containing the active ingredient were cancelled. When cancelled, pesticide products can no longer be offered for sale or sold, distributed, or used in New York.

Enforcement Discretion - Applicators and Businesses

November 24, 2020 -- certified pesticide applicators must now have a valid, current certification identification (ID) card in their possession to make any commercial or private applications of pesticides and registered pesticide businesses. Agencies need a current registration to operate as a pesticide business or agency.

February 24, 2021 -- DEC will assess penalty credits, related to recertification, as prescribed in regulation.

Neighbor Notifications in Spanish Language

2020 -- ECL now requires that the 48-hour prior notification for certain commercial lawn applications, the information sign posted by retailers, and the visual notification markers posted for residential lawn applications be printed in English and Spanish. Other languages may be necessary. The requirements of the amendments, like the Neighbor Notification Law, effect counties and cities with a population of one million or more, that have adopted a local law to "opt into" the Neighbor Notification Law in its entirety.

Stakeholder Meetings - Pesticide Regulations

DEC held stakeholder webinars to get input, on potential changes to pesticide regulations. Stakeholders heard about potential revisions, expressed views, provided input and participated to help develop comprehensive regulations.

Certified applicators and technicians need a valid certification ID card in their possession to work. Many will not be able to get the continuing education credits required for recertification because most classroom courses are cancelled in the near term. Enforcement discretion (see information in the right column on this page) to delay enforcement of the pesticide certification period is currently in place.

DEC will allow any applicator whose certification lapsed on or after November 1, 2019, to continue to operate until 60 days after the end of Executive Order 202 and any related extensions.

DEC will re-assess the situation periodically. If you are a certified applicator effected by this extension -- carry a copy of the enforcement discretion letter along with your ID. Show customers, inspectors, commercial permittees, and others that you are still allowed to operate.

Business Registration

If you are a business or agency, with registrations lapsed on or after March 1, 2020, you can continue to operate during the current crisis. This applies to 60 days after Executive Order 202 or any related extensions expire.

This allowance for business registration expiration also applies to the expiration date on the pesticide application equipment/vehicle decals. Equipment/vehicle operators can also carry a copy of the enforcement discretion letter as part of their proof that they can still operate.

Although applicators with expired certifications and businesses and agencies with expired registrations continue to operate during this time, pesticide applicators and pesticide businesses should submit their recertification and business registration renewal information to the DEC as soon as possible to avoid any delays in the processing. This will not change recertification dates and when the recertification paperwork is completed. Applicators will remain on their current recertification cycle.

Pesticide Products for Use Against COVID-19

Pesticide products used to disinfect surfaces or objects must be registered by the United States Environmental Protection Agency (EPA) and then by DEC. EPA has activated its Emerging Viral Pathogens Guidance for Antimicrobial Products to allow the use of certain EPA-registered disinfectant products against COVID-19.

DEC has created a list of products to disinfect COVID-19 (Updated October 8, 2021) (PDF) registered in New York State that correspond to the list of products identified by the EPA.

Note: This list is subject to change -- check back for updates.

DEC reminds users to follow the label directions for disinfecting surfaces for viruses, including adherence to contact times and appropriate personal protective equipment as listed on each product label.
