Overview of the Maine Natural Resources Protection Act

The Maine Natural Resources Protection Act (NRPA) is a state environmental regulation that operates within the broader framework of Maine's environmental laws. It was enacted in 1988 to protect Maine's natural resources, including rivers, streams, great ponds, fragile mountain areas, freshwater wetlands, significant wildlife habitat, coastal wetlands, and coastal sand dunes.¹

The primary state agency responsible for administering and enforcing the NRPA is the Maine Department positive environmental practices.[^1]The Act requires permits for activities that may have a significant impact on protected natural resources, such as dredging, bulldozing, removing or displacing soil, sand, vegetation, or other materials.²

Since its enactment, the NRPA has undergone several amendments to refine its scope and improve its effectiveness. The most recent significant amendment occurred in 2018, which clarified the definition of "significant groundwater well" and updated permit requirements for certain activities.³

The NRPA's approach to protecting natural resources involves a permitting process that assesses the potential impact of proposed activities on protected resources. It establishes standards for permit approval and grants the DEP the authority to deny permits for activities that would have an undue adverse effect on the environment.⁴

What does the Maine Natural Resources Protection Act protect?

The Maine Natural Resources Protection Act protects a variety of environmentally sensitive areas and resources across the state. These include:

1. Rivers, streams, and brooks
2. Great ponds
3. Fragile mountain areas
4. Freshwater wet inlands
5. Significant wildlife habitat
6. Coastal wetlands
7. Coastal sand dunes⁵

The NRPA protects these resources from activities that may cause harm, such as dredging, filling, removing, or displacing soil, sand, vegetation, or other materials. It achieves this protection through a permitting process that requires project proponents to demonstrate that their activities will not have an undue adverse impact on the protected resources.

REGULATORY SCOPE & JURISDICTION

Regulated Activities & Entities

The Maine Natural Resources Protection Act (NRPA) is a comprehensive environmental regulation that aims to protect the state's natural resources and ensure sustainable development. The Act regulates a wide range of activities and entities that have the potential to impact Maine's environment, including construction, industrial operations, and land use changes.

Under the NRPA, the following activities and entities are regulated⁶:

1. Construction projects, such as buildings, roads, and bridges
2. Industrial operations, including manufacturing, mining, and energy production
3. Land use changes, such as deforestation, wetland alteration, and shoreline development
4. Discharges of pollutants into water bodies, wetlands, and other protected areas
5. Alteration of wildlife habitats and ecosystems

The NRPA prohibits the following activities and substances due to their potential to cause significant environmental harm:

1. Discharge of toxic substances, such as heavy metals and persistent organic pollutants, into protected areas
2. Destruction or alteration of critical wildlife habitats, such as breeding grounds and migration routes
3. Development within designated shoreland zones without proper permits and mitigation measures
4. Filling or dredging of wetlands without appropriate permits and compensation
5. Introduction of invasive criminal species that can disrupt native ecosystems

These prohibitions are based on the understanding that certain activities and substances pose unacceptable risks to Maine's natural resources, biodiversity, and public health. By regulating these activities and entities, the NRPA seeks to strike a balance between economic development and environmental protection, ensuring that Maine's unique natural heritage is preserved for future generations.

Structure and Key Provisions

The Maine Natural Resources Protection Act is structured into several key sections that outline its purpose, definitions, permitting requirements, and enforcement provisions. The Act is designed to be comprehensive, covering a wide range of activities and resources, while also providing clear guidance to regulated entities and government agencies.

Section 480-A: Findings; Purpose; Scope⁷

This section establishes the legislative findings that underpin the NRPA, emphasizing the importance of protecting Maine's natural resources and the need for a comprehensive regulatory framework. It also outlines the Act's purpose and scope, setting the stage for the subsequent sections.

Section 480-B: Definitions

The definitions section provides clear explanations of key terms used throughout the Act, such as "protected natural resource," "significant wildlife habitat," and "coastal wetland." These definitions are essential for understanding the Act's applicability and requirements.

Section 480-C: Prohibitions

This section outlines the activities that are prohibited under the NRPA, such as unauthorized filling or dredging of wetlands, discharges of pollutants into protected areas, and destruction of significant wildlife habitats. It also establishes the framework for permitting and mitigation requirements.

Section 480-D: Standards

The standards section sets forth the criteria that must be met for a proposed activity to be permitted under the NRPA. These standards cover issues such as water quality, habitat protection, and erosion control, among others. This section is crucial for understanding the factors that the regulatory agencies will consider when evaluating permit applications.

Section 480-E: Permit Processing Requirements

This section outlines the procedural requirements for permit applications, including submission deadlines, public notice and comment periods, and agency review timelines. It also establishes the framework for permit conditions and mitigation requirements.

COMPLIANCE REQUIREMENTS & STANDARDS

Regulatory Standards & Limitations

The Maine Natural Resources Protection Act (NRPA) establishes various standards and limitations to protect the state's natural resources, including rivers, streams, great ponds, fragile mountain areas, freshwater wetlands, significant wildlife habitat, coastal wetlands, and coastal sand dunes.⁸ These standards are implemented through a permit system administered by the Maine Department of Environmental Protection (DEP).⁹

The NRPA sets forth performance standards for activities in protected natural resources, such as:

• Limits on the extent of alteration or disturbance allowed in wetlands, waterbodies, and other protected areas¹⁰
• Requirements for minimizing erosion and sedimentation¹¹
• Standards for maintaining water quality and flow¹²
• Criteria for protecting significant wildlife habitat and other sensitive ecological areas¹³

Developers and consultants must carefully review these standards and work closely with the DEP to ensure their projects comply with all applicable requirements. Failure to meet these standards may result in denial of a permit or enforcement action by the DEP.¹⁴

Monitoring, Reporting & Recordkeeping Obligations

Under the NRPA, regulated entities may be required to conduct monitoring, maintain records, and submit reports to demonstrate compliance with permit conditions and regulatory standards. The specific monitoring, reporting, and recordkeeping requirements will depend on the nature and scope of the regulated activity and the conditions of the permit issued by the DEP.¹⁵

Examples of potential monitoring and reporting obligations include:

• Water quality monitoring¹⁶
• Wildlife surveys¹⁷
• Wetland vegetation monitoring¹⁸
• Erosion and sedimentation control inspections¹⁹

Developers and consultants should work closely with the DEP to understand and fulfill the specific monitoring, reporting, and recordkeeping requirements that apply to their projects. Proper documentation and timely submission of required reports are essential for maintaining compliance and avoiding enforcement actions.²⁰
