Benthic Barrier Permit Regulations for New York

New York State Regulations on Aquatic Weed Control

New York State is committed to preserving its aquatic ecosystems while allowing for effective control of invasive aquatic plants. Benthic barriers are one such tool used for managing these plants, but their use is regulated to ensure minimal environmental impact.

Many states have regulations on weed control products. However, they are frequently unable to enforce them. We have customers in every state.

Benthic Barriers General Overview

Benthic barriers are underwater mats placed on lake or pond beds to block sunlight, ultimately killing the plants beneath them. They are particularly useful for small-scale, localized weed control efforts.

Invasive Aquatic Plants In New York

New York faces challenges with several invasive aquatic plants, including Eurasian Watermilfoil and Water Chestnut. These plants can disrupt local ecosystems, out-compete native vegetation, and impair recreational water use.

New York Benthic Barriers Restrictions and Guidelines

To use benthic barriers in New York, property owners must adhere to the following guidelines:

  1. Permit Requirement: The DEC requires a permit for benthic barrier installation via the Joint Application Form. It falls under General Permit GP-0-21-004. For additional help, you can access the Joint Application Form Instructions and the Joint Application Form.
  2. Authorized Use Period: Barriers can be used from July 1 to October 31.
  3. Area Restrictions: Usage is limited to designated areas, such as freshwater wetlands, protected streams, and navigable waters. Your waterfront is permissible.
  4. Barrier Specifications: Barriers must be either gas permeable or have a gas venting method incorporated in the barrier, and anchored appropriately.

Environmental Considerations For New York

The use of benthic barriers is subject to environmental considerations to protect the aquatic ecosystem:

  • Avoiding coverage of spawning beds.
  • Ensuring barriers are removed after the authorized period.
  • Preventing the use of lake bed stones for anchoring.

Additional Considerations

Compliance with these regulations is essential to avoid penalties and ensure the conservation of New York’s waterways. Property owners must submit detailed project plans, including targeted species, area size, and management techniques.

Adhering to the benthic barrier permit regulations is crucial for managing invasive aquatic plants responsibly. By following these guidelines, property owners can help preserve the ecological balance of New York’s water bodies.
