A. 
Introduction. These regulations are promulgated by the Town of Nantucket Conservation Commission (hereinafter referred to as the "Commission") pursuant to the authority granted to it under Chapter 136, Wetlands, § 136-7, of the Code of the Town of Nantucket (hereinafter referred to as the "Bylaw"). The regulations should be read together with the Bylaw, which has many important provisions not to be repeated in these regulations. These regulations shall be used to enforce and implement the Bylaw, and shall have the force of law upon their effective date. These regulations supersede all existing rules and practices previously applicable to procedures and proceedings before the Commission.
B. 
Purpose. The purpose of these regulations is to establish definitions, design standards, and uniform procedures by which the Nantucket Conservation Commission is to carry out its responsibilities under the Bylaw.
The definitions in this § 390-2 are for terms as used in the Bylaw and for terms as used in these regulations. To the extent not defined herein or in the Bylaw, words used in the Bylaw or in the regulations shall have the definitions contained in the Massachusetts Wetlands Protection Act (MGL c. 131, § 40) and the rules and regulations promulgated thereunder.
ABUTTER
An owner of land in any direction sharing a common boundary with the site of the proposed activity, including any land located directly across a street, way, stream, pond, or diagonally across from an intersection of roads. A landowner more than 300 feet across a pond shall not be considered an abutter.
ACTIVITY
Same as the definition of "work."
ADVERSE IMPACT
A greater-than-negligible change in the resource area or one of its characteristics, functions or factors that diminishes the value of the resource area to one or more of the specified interests in Chapter 136, Wetlands, of the Code of the Town of Nantucket, as determined by the Commission. "Negligible" means small enough to be disregarded and shall be defined in relation to the wetland resource areas impacted.
AGRICULTURAL PRACTICES
A. 
LAND IN AGRICULTURAL USEAny qualifying wetland within a farm which is qualified or eligible to be qualified under the Farmland Assessment Act, MGL c. 61A § 1 through § 5.
B. 
QUALIFYING WETLANDOnly inland freshwater areas which are seasonally flooded basins or flats or inland fresh meadows.
C. 
(1) 
Shall mean only:
(a) 
Tilling practices customarily employed in the raising of crops.
(b) 
Pasturing of animals, including such fences and protective structures as may be required.
(c)

Upon written request by the applicant, a Nantucket certificate of compliance may be issued by the Commission, which shall certify that the conditions required by the permit as of the date of the application for a Nantucket certificate of compliance have been completed in compliance with the permit. If issued by the Commission, the certificate of compliance shall be signed by a majority of the Commission.
(2) 
If a project has been completed in accordance with plans stamped by a registered professional engineer, architect, landscape architect, or land surveyor, a written statement by such a professional person certifying substantial compliance with the plans and setting forth any deviation that exists from the plans approved in the order shall accompany the request for a certificate of compliance. The required as-built plan shall show all wetland areas, buffer zones, topography, other landscape features relevant to the project and any differences to the approved project.
(3) 
Prior to the issuance of a certificate of compliance, the Commission may make a site visit, in the presence of the applicant or, if the applicant so desires, in the presence of the applicant's agent.
(4) 
Partial certificates of compliance will not be issued by the Commission, except for rare and extenuating circumstances. The burden of proof to substantiate these circumstances shall be with the applicant.

Waivers of requirements.
(1) 
All requests for waivers shall be in writing.
(2) 
The Commission may, in its discretion, for good cause shown, grant waivers from the operation of one or more of these regulations pursuant to this subsection. Such waivers shall be granted only in accordance with the provisions of this subsection.
(3) 
A waiver shall be granted only for the following reasons and upon the following conditions:
(a) 
The Commission may grant a waiver from these regulations when the Commission finds that, given existing conditions, the proposed project will not adversely impact the interests identified in the Bylaw and there are no reasonable conditions or alternatives that would allow that project to proceed in compliance with the regulations. The burden of proof to show no adverse impact to the interests identified in the Bylaw, Chapter 136, Wetlands, § 136-2, of the Code of the Town of Nantucket, shall be the responsibility of the owner/applicant. The burden of proof to show no reasonable alternative shall be the responsibility of the owner/applicant and shall consist of a written alternatives analysis detailing why the proposed project cannot otherwise proceed in compliance with the performance standards in these regulations, with an explanation of why each is not feasible. It shall be the responsibility of the applicant to provide the Commission with any information which the Commission may request in order to enable the Commission to ascertain such adverse effects. The failure of the applicant to furnish any information which has been so requested may result in the denial of a request for a waiver pursuant to this subsection.
(b) 
The Commission may grant a waiver from these regulations when portions of the buffer zone between the proposed project and adjacent resource area are previously altered and are not within the control of the project owner/applicant, such as public or semi-public pedestrian and vehicular accessways.
(c) 
The Commission may grant a waiver from these regulations when the Commission finds that a project will provide a long-term net benefit/improvement to the resource area, provided any adverse effects are minimized by carefully considered conditions. However, no such project may be permitted which could have an adverse effect on rare wildlife species.
(d) 
The Commission shall grant a waiver from these regulations when the work proposed is grandfathered and qualifies as a preexisting use, as defined in § 390-2 of these regulations.
(4) 
The Commission may impose additional conditions in granting a permit pursuant to this section, including imposing limits on project size or effect or requiring other compensatory measures, such as wetland replication.
