DEC Releases Proposed Regulation to Prohibit Pesticides Containing Chlorpyrifos

From the NYS Department of Environmental Conservation Press Release: 

The proposed regulation is in today's State Register and DEC is accepting public comments on the proposal from Jan. 27 through April 5, 2021.

This proposed regulation will add chlorpyrifos to the list of prohibited pesticides in 6 NYCRR 326.2(c) of New York's pesticide registration regulations. Scientific research has shown that chlorpyrifos can harm the development of the nervous systems of infants and young children. Prenatal exposure to organophosphates can result in diminished cognitive ability, delays in motor development, and Attention-Deficit/Hyperactivity Disorder (ADHD).

Information concerning the review process proposed rulemaking, and supporting documents can be accessed from DEC's website or at DEC, 625 Broadway, Albany, NY 12233. To review the documents at DEC's Central Office, call Melissa Treers for an appointment at (518) 402-8678 or email

To submit written comments via email, write to with "Comments on Proposed Part 326" in the subject line of the email. Comments submitted by mail should be sent to DEC's Pesticide Enforcement & Compliance Assurance Section, NYSDEC, Division of Materials Management, 625 Broadway, Albany, NY 12233-7254. DEC is accepting public comments on the proposed regulation through April 5, 2021.

The application of pesticides must be done in a manner that is protective of public health and the environment and New York State's pesticide regulatory program is a national leader in the review and registration of pesticides, implementation of regulatory controls, and the enforcement of the worker protection standard. State law affords DEC with a broad range of regulatory powers including the ability to restrict the use of a pesticide and revoke pesticide registrations.

To complement this regulation, DEC canceled the registration of 29 pesticides containing chlorpyrifos on Dec. 31, 2020, and is canceling the registration of the remaining 15 pesticides as of July 31, 2021. Following cancellation, a pesticide can no longer be sold, distributed, or used in New York State. In addition, these canceled pesticides cannot be stored after the manufacturer's container has been opened. DEC recommends the public to check the New York State pesticide registration status of these products on the New York State Pesticide Administration Database. If the pesticide is not currently registered in New York State, consult with pesticide distributors or the manufacturer to determine the appropriate options for removal or disposal of the pesticide.

In addition, DEC is holding a virtual public comment hearing for the proposed rule at 6 p.m. on March 30. The electronic webinar format is reasonably accessible to persons with impaired mobility. Instructions on how to join the hearing, how to provide an oral statement, and how to register are available at DEC's website. Contact DEC at (518) 402-9003 with any additional questions regarding the virtual hearing.

Notice of New York State Department of Environmental Conservation (NYS DEC) Program Policy
DAR-1: "Guidelines for the Evaluation and Control of Ambient Air Contaminants" under 6 NYCRR Part 212, "Process Operations"

Part 212 is used in conjunction with other state and federal regulations to control criteria and non-criteria air contaminants. Non-criteria air contaminants are also referred to as toxic air contaminants and Part 212 is not limited to the air contaminants listed in the DAR-1 document. This policy is written to provide guidance for the implementation of and compliance with Part 212. This document issued by NYS DEC outlines the procedures for evaluating the emissions of air contaminants from process operations in New York State. Incorporated within the policy document are three flow charts to aid the end user when identifying applicable process emission sources, establishing uniform Environmental Ratings, and ascertaining the proper degree of control for applicable process emission sources.
This policy replaces DAR-1 previously issued on August 10, 2016 by the Division of Air Resources. This document provides guidance to NYS DEC staff, those facility owners subject to Part 212, and the general public. More specifically, this guidance document discusses how NYS DEC intends to implement Part 212. The guidance contained in this document is primarily intended for use in conjunction with NYS DEC's permitting and regulatory authority found in 6 NYCRR Parts 200, 201, 212 and 257.
The following represents the major changes included in the year 2020 Annual Guideline Concentration and Short-Term Guideline Concentration (AGC/SGC) Tables:

  1. As stated in previous AGC/SGC Table versions, many federal and state ambient air quality standards are not based upon one-hour or annual averaging periods. For these standards, it is difficult to assess compliance using the DAR-1 screening procedures. As such, DAR-1 "equivalent" one-hour and annual standards have been derived using averaging time conversion factors. These "equivalent" standards act as screening surrogates for assessing compliance with those federal and state standards not based upon one-hour or annual averaging periods. Appendix A of DAR-1 directs the reader to review DAR-10 when assessing compliance with all federal and state standards.

  2. The SGC for benzene has been revised from 1300 to 27 ug/m3. NYS DEC and the New York State Department of Health (NYS DOH) agree with the Office of Environmental Health Hazard Assessment (OEHHA) from California that potential health effects can occur at lower exposure concentrations than previously identified. The AGC for ethylene oxide has been revised. Data from the United States Environmental Protection Agency’s (US EPA) EPA Integrated Risk Information System’s (IRIS) cancer risk assessment has shown potential cancer health risks at concentrations previously allowed. NYS DEC and NYS DOH agree with the IRIS assessment and have revised the AGC accordingly.

  3. NYS is listing an AGC for perfluorooctanoic acid (PFOA) in the 2020 AGC/SGC tables. NYS DEC notes that several authoritative bodies, including the US EPA and NYS DOH, have derived oral toxicity values for PFOA using generally accepted risk assessment practices. The NYS DOH recently evaluated authoritative-body risk assessments and derived cancer and noncancer toxicity values for PFOA based on systemic effects observed in oral studies of laboratory animals. These oral toxicity values were used to derive a guideline concentration for PFOA in air using route-to-route exposure extrapolation.

Written comments on the proposed guidance may be submitted until 5:00 p.m. February 12, 2021.

Best Practices in Evaluating Environmental Compliance and Permitting Obligations for Changes at a Chemical Facility

    Presented by Brian Noel and Ellen Hewitt of Trinity Consultants 


Chemical Facilities are constantly undergoing changes.  

This presentation will provide case studies for changes occurring at chemical facilities and the practical methodologies utilized to determine the impact on Title V permitting and Federal Regulations.  Facility changes can trigger many questions including, will emissions are impacted, the effect on notifications, potential triggering of NSPS or MACT standards, does retest need to be completed, etc. 



Topics will include:
* Best practices for performing environmental review

- Key terms, probing questions, and real-world examples
- Identifying what changes have impact on environmental requirements
- Common mistakes or gaps in MOC processes
