GP 22. Aquaculture (Authorities: §§10 and 404)
(a) The installation of buoys, floats, racks, trays, nets, lines, tubes, containers, and other structures into navigable
waters of the U.S.; (b) Discharges of dredged or fill material into waters of the U.S. necessary for shellfish seeding,
rearing, cultivating, transplanting, and harvesting activities; and (c) Shellfish seeding or brushing the flats projects.
The area and any elevated structures within it must be marked in conformance with 33 CFR 64, and the permittee
must contact the USCG, First District, Aids to Navigation Branch (617) 223-8347 to coordinate the proper buoy
markings for the activity. Buoys shall be deployed and maintained as appropriate. Any fill material imported to the
project from offsite (this is limited to mineral growth medium used in culture trays) shall be clean and of comparable
grain size to the native substrate.
Not authorized under GP 22 (IP required): (a) New, or expansions of, impoundments and semi-impoundments of
waters of the U.S. for the culture or holding of motile species such as lobster with an impounded area >½ acre;
(b) Cultivation of a nonindigenous species (see Note 1) unless that species has been previously cultivated in the
waterbody; (c) Cultivation of an aquatic nuisance species (see Note 1); (d) Attendant features such as docks, piers,
boat ramps, stockpiles, or staging areas, or the deposition of shell material back into waters of the U.S. as waste;
(e) Private sites >10 acres or municipal areas >25 acres; (f) Rafts and other floating equipment that cover >10% of the
project area or 20,000 SF, whichever is greater. An area is considered covered with floating equipment if normal
navigation through the area is precluded; or (g) Activities, including any vehicular access, that negatively impact
coastal or freshwater wetlands, or with more than minimal negative impacts on: (1) Avian resources such as, but not
limited to, shore birds, wading birds, or members of the waterfowl group. This is meant to include migratory bird
nesting, feeding or resting activities (see 50 CFR 10.13); or (2) Existing or naturally occurring beds or population of
shellfish, marine worms or other invertebrates that could be used by humans, other mammals, birds, reptiles, or
predatory fish.
Self-Verification Eligible
1
: Devices and activities that do not require a PCN or an IP.
1. Permanent & temporary impacts in tidal or non-tidal waters of the U.S. including cultch or spatted shell; or
2. Structures such as cages, trays, racks, bags, rafts or other floating equipment. However, structures are SV eligible
provided a PCN is not required elsewhere in this document and they are: (a) located within the footprint of an
existing authorized fixed or floating structure in which case in-water lines, ropes or chains may be used;
(b) comprised of floating upweller docks totaling ≤640 SF in area; (c) structures (e.g., cages, racks) elevated ≥2 feet
above the ocean floor with legs within a lease site with ≤4 buoys marking the corners an no other lines; or (d) floating
cage strings with a single connecting line, ≤2 anchors and ≤2 end marker buoys per string within a lease site with ≤4
buoys marking the corners; and
3. Research, educational, commercial-viability or experimental aquaculture gear activities for indigenous species; or
4. Activities include a species not previously cultivated in the waterbody; or
5. Kelp or finfish aquaculture; or
6. Land-based hatchery intakes >3 inches in diameter; or
7. Activities in water depths >10 feet mean low lower water (MLLW); or
8. Activities with in-water lines, ropes or chains (see exceptions in 2(a), (c) and (d) above); or
9. Activities occur in SAS or involve mechanical or hydraulic dredging;
10. Activities occur in the Connecticut River from the Turners Falls Dam to the MA/CT border or the Merrimack
River from the Essex Dam to the mouth. This is to protect endangered species; or
11. New, or expansions of, impoundments and semi-impoundments of waters of the U.S. for the culture or holding of
motile species such as lobster with an impounded area ≤1/2 acre; or
12. Aquaculture facilities <25 acres applied for by municipalities; or
13. Activities that do not require an IP. Activities that do not require a PCN or an IP may be SV eligible.
Notes: (1) The Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990 defines: (a) nonindigenous
species as “any species or other viable biological material that enters an ecosystem beyond its historic range, includ-
ing any such organism transferred from one country into another”; and (b) aquatic nuisance species as “a nonindig-
enous species that threatens the diversity or abundance of native species or the ecological stability of infested waters,
or commercial, agricultural, aquacultural, or recreational activities dependent on such waters.” (2) Aquaculture
applicants do not need to notify the SHPO since these projects are unlikely to affect historic or archaeological
resources, but must notify the BUAR and applicable tribes per GC 7(c). (3) The MA Shellfish Planting Guidelines
