Overview of the Connecticut Inland Wetlands & Watercourses Act

The Connecticut Inland Wetlands & Watercourses Act (IWWA) is a state law that operates within the broader framework of Connecticut's environmental regulations. It works in conjunction with federal regulations such as the Clean Water Act to protect the state's wetlands and watercourses.

The primary goals of the IWWA are to protect, preserve, and regulate activities that may impact inland wetlands and watercourses in Connecticut. The Act recognizes the importance of these resources for maintaining water quality, providing wildlife habitat, and supporting recreational activities.

The Connecticut Department of Energy and Environmental Protection (DEEP) is responsible for administering and enforcing the IWWA at the state level. However, the Act also requires each municipality in Connecticut to establish an Inland Wetlands Agency to regulate activities affecting wetlands and watercourses within their jurisdiction.

The IWWA was first enacted in 1972 and has undergone several amendments over the years. Notable changes include expanding the definition of regulated activities and increasing the penalties for violations.

The Act achieves its goals by requiring permits for activities that may impact wetlands or watercourses, such as dredging, filling, or construction. It also establishes buffer zones around these resources and requires mitigation for unavoidable impacts.

What does the Connecticut Inland Wetlands & Watercourses Act protect?

The Connecticut Inland Wetlands & Watercourses Act protects inland wetlands and watercourses throughout the state. Wetlands are defined as areas that consist of soil types designated as poorly drained, very poorly drained, alluvial, or floodplain by the National Cooperative Soils Survey. Watercourses include rivers, streams, brooks, waterways, lakes, ponds, marshes, swamps, bogs, and all other bodies of water, natural or artificial. The IWWA protects these resources from pollution, disturbance, and destruction caused by development, construction, and other human activities. The Act achieves this protection by requiring permits for regulated activities, establishing buffer zones, and mandating mitigation measures when impacts are unavoidable.

REGULATORY SCOPE & JURISDICTION

Regulated Activities & Entities

The Connecticut Inland Wetlands & Watercourses Act (IWWA) is a comprehensive state legislation aimed at protecting and preserving the state's inland wetlands and watercourses from adverse impacts caused by human activities. The Act regulates a wide range of activities and entities that may potentially harm these sensitive ecosystems, including construction, industrial operations, and land development projects.

Under the IWWA, the following activities and substances are prohibited due to their potential to cause significant environmental damage to inland wetlands and watercourses¹:

1. Dredging, excavation, or removal of soil, mud, sand, gravel, peat, or other material from wetlands or watercourses.
2. Dumping, filling, or depositing of material into wetlands or watercourses, including but not limited to soil, stones, sand, gravel, mud, debris, or waste materials.
3. Construction, reconstruction, or expansion of buildings, roads, or other structures within or adjacent to wetlands or watercourses.
4. Diversion, alteration, or obstruction of water flow within wetlands or watercourses, including changes in velocity, volume, or course.
5. Pollution of wetlands or watercourses through the discharge of sewage, industrial waste, or other pollutants, such as chemicals, oil, or heated effluents.
6. Clear-cutting or other significant removal of vegetation in or adjacent to wetlands or watercourses.

These prohibitions are essential for maintaining the ecological integrity, water quality, and biodiversity of Connecticut's inland wetlands and watercourses. By regulating these activities, the IWWA seeks to prevent the degradation or destruction of these valuable natural resources, which provide critical habitats for flora and fauna, help control flooding, and contribute to the overall health of the state's environment².

Structure and Key Provisions

The Connecticut Inland Wetlands & Watercourses Act is structured into several key sections that outline definitions, prohibitions, permitting requirements, and enforcement provisions. The most important sections for developers and consultants to be aware of include:

Section 22a-36: Legislative Finding³

This section establishes the legislative intent behind the IWWA, emphasizing the importance of protecting inland wetlands and watercourses as an indispensable and irreplaceable natural resource.

Section 22a-38: Definitions

This section provides clear definitions for key terms used throughout the Act, such as "wetlands," "watercourses," "person," and "regulated activity." Understanding these definitions is crucial for determining the applicability of the IWWA to a given project.

Section 22a-41: Factors for Consideration of Commissioner

This section outlines the factors that the Commissioner of Energy and Environmental Protection must consider when deciding on permit applications, such as the environmental impact of the proposed activity, any feasible and prudent alternatives, and the relationship between short-term uses of the environment and the maintenance and enhancement of long-term productivity.

Section 22a-42a: Municipal Regulation of Wetlands and Watercourses

This section grants municipalities the authority to establish inland wetlands agencies and adopt local regulations for protecting wetlands and watercourses within their jurisdiction. It also outlines the procedures for permit applications, public hearings, and appeals at the municipal level.

While these sections provide an overview of the IWWA's structure and key provisions, it is essential for developers and consultants to consult the full text of the regulation and engage with the relevant state and local agencies for project-specific guidance. The Act's complexity and the unique characteristics of each project site necessitate a thorough understanding of the legislation and its application to ensure compliance and minimize environmental impacts.
