Chapter 2 - AQUACULTURE LEASE REGULATIONS
Section 188-2-37 - Decision

(1) Riparian Owners Ingress and Egress. The Commissioner shall examine whether the riparian owners can safely navigate to their shore. The Commissioner shall consider the type of shore involved and the type of vessel that can reasonably land on that shore. The Commissioner shall consider the type of structures proposed for the lease and their potential impact on the vessels which would need to maneuver around those structures.

(2) Navigation. The Commissioner shall examine whether any lease activities requiring surface and or subsurface structures would interfere with commercial or recreational navigation around the lease area. The Commissioner shall consider the current uses and different degrees of use of the navigational channels in the area in determining the impact of the lease operation. High tide "short cuts" shall not be considered navigational ways for the purposes of this section.

(3) Fishing. The Commissioner shall examine whether the lease activities would unreasonably interfere with commercial or recreational fishing or other water-related uses of the area. This examination shall consider such factors as the number of individuals that participate in recreational or commercial fishing, the amount and type of fishing gear utilized, the number of actual fishing days, and the amount of fisheries resources harvested from the area.

(4) Other Aquaculture Uses. The Commissioner shall consider any evidence submitted concerning other aquaculture uses of the area. The intensity and frequency of such uses as well as the degree of exclusivity required for each use shall be factors in the Commissioner's determination of whether any interference is unreasonable. The number, size, location, and type of other aquaculture leases shall be considered by the Commissioner.

(5) Existing System Support. The Commissioner shall consider the degree to which the use of the lease site will interfere with significant wildlife habitat and marine habitat or with the ability of the lease site and marine and upland areas to support ecologically significant flora and fauna. Such factors as the degree to which physical displacement of rooted or attached marine vegetation occurs, the amount of alteration of current flow, increased rates of sedimentation or sediment resuspension, and disruption of finfish migration shall be considered by the Commissioner in this determination.

(6) Source of Organisms to be Cultured. The Commissioner shall include but not be limited to, consideration of the source's biosecurity, sanitation, and applicable fish health practices.

(7) Interference with Public Facilities. The Commissioner shall consider the degree to which the lease interferes with public use or enjoyment within 1,000 feet of a beach, park, docking facility or certain conserved lands owned by the Federal Government, the State Government or a municipal government. Conserved lands means land in which fee ownership has been acquired by the state, federal or municipal government in order to protect the important ecological, recreational, scenic, cultural or historic attributes of that property. In determining interference with the public use or enjoyment of conserved lands, the Commissioner shall consider the purpose(s) for which the land has been acquired.

(8) Lighting

Applicability. These rules apply to all exterior lighting used on buildings, equipment, and vessels permanently moored or routinely used at all aquaculture facilities, with the exception of lighting for navigation, emergencies, and construction of a temporary nature.

Exterior lighting. All exterior lighting shall be mounted in cutoff fixtures. A cutoff fixture is one that projects no more than 2.5% of light above the horizontal plane of the light fixture's lowest part. This does not include spotlights or floodlights, which are addressed below.

All exterior lighting shall be designed, located, installed, and directed in such a manner as to illuminate only the target area and to reduce glare.

Exterior lighting shall be no more than 250 watts per fixture, with the exception of required navigational lighting, spotlights and floodlights.

When harvest schedules, feed schedules, or other similar circumstances result in the need to work beyond daylight hours, spotlights or floodlights may be used to ensure safe working conditions and safe vessel operation. Such lighting shall be directed only at the work area to be illuminated, and must be the minimum needed for safe operations.

If used, all husbandry lighting shall be submersible and operated at all times below the water line, except during examination for maintenance and repair.

When necessary, security lighting may be used, but shall conform to the requirements for exterior lighting.

An applicant shall demonstrate that all reasonable measures will be taken to mitigate light impacts from the lease activities.

No provision in these rules is intended to restrict vessel lighting levels below what is necessary for safety or as is otherwise required by state or federal law.

(9) Noise

Applicability. These rules apply to the routine operation of all aquaculture facilities, including harvesting, feeding, and tending equipment at leases authorized by the Department of Marine Resources, with the following exemptions:

Watercraft, harvest or transport barges, and maintenance equipment while underway; The unamplified human voice and other sounds of natural origin; Bells, whistles, or other navigational aids; Emergency maintenance and repair of aquaculture equipment; Warning signals and alarms; and Events not reasonably within the control of the leaseholder.

Mitigation:

All motorized equipment used during routine operation at an aquaculture facility must be designed or mitigated to reduce the sound level produced to the maximum extent practical.

Centralized feeding barges, or feeding distribution systems, shall be designed or mitigated to reduce noise by installing the most effective commercially available baffles at air intakes and outlets, mounting of all relevant equipment to minimize vibration between it and the hull, and using the most effective commercially available soundproofing insulation.

All fixed noise sources shall be directed away from any residences or areas of routine use on adjacent land.

An applicant shall demonstrate that all reasonable measures will be taken to mitigate noise impacts from the lease activities.

(10) Visual Impact

Applicability. This rule applies to all equipment, buildings, and watercraft used at an aquaculture facility, excluding watercraft not permanently moored or routinely used at a lease location such as harvest or feed delivery vessels. Other equipment or vessels not moored within the boundaries of a lease, but routinely used or owned by the leaseholder are subject to these requirements.

Building profiles. The size, height, and mass of buildings and equipment used at aquaculture facilities shall be constructed so as to minimize the visual impact as viewed from the water.

Height limitations. All buildings, vessels, barges, and structures shall be no more than one story and no more that 20 feet in height from the water line. Height shall be measured from waterline to the top of the roof or highest fixed part of the structure or vessel. This height limitation excludes antennae, cranes, and other similar auxiliary equipment. Structures that exist as of April 1, 2018 are exempted from the height restriction for their useful lifetime.

Roof & siding materials. Roofing and siding materials shall not be reflective or glossy in appearance or composition.

Color. Equipment and structures shall be painted, or be of, a color that does not contrast with the surrounding area. Acceptable hues are grays, blacks, browns, blues, and greens that have a sufficiently low value, or darkness, so as to blend in with the surrounding area. Colors shall be flat, not reflective, in appearance.

The color of equipment, such as buoys, shall not compromise safe navigation or conflict with US Coast Guard Aids to Private Navigation standards.

(1) A harbormaster and/or a municipal officer or other designee of the municipality in which the proposed lease is predominantly located may recommend that the Commissioner establish conditions on a proposed lease in writing to the Department during the comment period. The Department shall consider any conditions recommended by the municipality, and the Department shall provide a written explanation to the municipality at the time a proposed decision is written if any of the requested conditions will not be included in the lease.

(2) The Commissioner may grant the lease on a conditional basis until the lessee has acquired all the necessary federal, state and local permits.

(3) The Commissioner may require that monitoring including testing be conducted on lease sites. Such monitoring shall: be conducted by the lease holder or the lease holder's agent; be undertaken on a schedule to be determined by the Commissioner; and shall include the information designated by the Commissioner in the lease decision, which may include, but is not limited to, an analysis of water chemistry, phytoplankton, zooplankton, and fish larvae profiles. The results of such monitoring shall be summarized in a written report and submitted to the Department within 90 days of completion of each study.

(4) The Commissioner may establish any reasonable requirements to mitigate interference, including but not limited to restrictions on:

(5) Within 120 days after the hearing on an application, the Commissioner shall render a final decision.

(6) The Commissioner's denial or approval of a lease application shall be considered final agency action for purposes of judicial review.
