Issuance of a General Permit for Ocean Disposal of Marine Mammal 
and Sea Turtle Carcasses

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability of final general permit.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is re-issuing a 
general permit under the Marine Protection, Research and Sanctuaries 
Act (MPRSA) to authorize the transport of marine mammal and sea turtle 
carcasses from the United States and disposal of marine mammal and sea 
turtle carcasses in ocean waters. Permit re-issuance is necessary 
because the most recent permit expired on January 4, 2024. The EPA has 
not made substantive changes to the content of the recently expired 
general permit, though it has revised the scope and eligibility 
provisions, and general permittees will be able to resume permitted 
deposition of marine mammal carcasses in ocean waters pursuant to the 
re-issued permit terms.

DATES: This permit is effective on August 15, 2025 and expires on July 
16, 2032.

ADDRESSES: The EPA established a docket for this action under Docket ID 
No. EPA-HQ-OW-2023-0329. All documents in the docket are listed on the 
https://www.regulations.gov website.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    The authorization in this general permit is available for any 
officer, employee, agent, department, agency, or instrumentality of 
Tribal, Federal, State or local unit of government, as well as any 
Marine Mammal Health and Stranding Response Program (MMHSRP) Stranding 
Agreement Holder, authorized members of the Sea Turtle Stranding and 
Salvage Network (STSSN), any Alaska Native, and members of the Makah 
Indian Tribe already authorized to take a marine mammal under the 
Endangered Species Act (ESA) or Marine Mammal Protection Act (MMPA), to 
transport from the United States and dispose of a marine mammal or sea 
turtle carcass in ocean waters.

B. Does this action require the disposal of marine mammal or sea turtle 
carcasses in ocean waters?

    The general permit does not require ocean disposal of marine mammal 
or sea turtle carcasses; it merely authorizes ocean disposal when there 
is a need for disposition of such carcasses in ocean waters.

C. Why does the EPA permit ocean disposal of marine mammal and sea 
turtle carcasses?

    The disposition of marine mammal and sea turtle carcasses in ocean 
waters is not excluded from the statutory definition of ``dumping'' or 
otherwise excluded from the scope of the Marine Protection, Research, 
and Sanctuaries Act (MPRSA), as such the transportation and disposition 
of any material, including carcasses, in ocean waters requires a permit 
under the MPRSA.

D. Why does this action require reporting?

    Given the natural and unnatural deaths of marine mammals and sea 
turtles at sea, the disposal of marine mammal or sea turtle carcasses 
into the ocean is not anticipated to have any adverse effect on human 
health, fisheries resources, or marine ecosystems. Under the MPRSA 
regulations (40 CFR 224.1 and 224.2), each person dumping materials 
under a general permit must maintain records of the physical and 
chemical characteristics of the material dumped, the times and 
locations of the dumping, and any other information required as a 
condition of the permit. Dumping records must be reported to the EPA as 
required under the general permit. Additionally, to meet the United 
States' international treaty obligation for reporting under the London 
Convention, the EPA reports information about disposals under this 
general permit, and all other activities authorized under the MPRSA, 
annually to the International Maritime Organization, which provides 
administrative support on behalf of the treaty parties.

II. Federal Law and International Conventions

    Except as excluded from the definition of dumping in the MPRSA (or 
otherwise excluded), the transportation for the purpose of dumping and 
dumping of any material in ocean waters requires authorization under 
the MPRSA. The MPRSA defines the term ``dumping'' broadly to encompass 
the disposition of material both for the purpose of disposal and for 
purposes other than disposal. The exclusion for purposes other than 
disposal is limited. Section 102(a)(A) of the MPRSA and implementing 
regulations at 40 CFR 227.14 through 227.16 direct the EPA, in issuing 
a permit and/or evaluating a permit application, to consider the need 
for ocean dumping as well as alternatives to ocean dumping.
    The MPRSA implements the United States' obligations under the 
London Convention, the international treaty that protects the marine 
environment from the dumping of wastes and other matter into the ocean. 
Contracting Parties to the London Convention agreed to control dumping 
by implementing regulatory programs to assess the need for, and the 
potential impact of, dumping. The London Convention requires 
Contracting Parties to issue a permit for the dumping of wastes and 
other matter at sea, to prohibit dumping of some materials, and to 
report annually on all permits issued and monitoring activities 
undertaken.
    For the at-sea disposition of marine mammal and sea turtle 
carcasses, the EPA establishes terms for MPRSA permit authorization, 
but other Federal laws also are implicated. The MPRSA general permit 
only purports to authorize the transportation for the purposes of 
disposal and disposal of marine mammal and sea turtle carcasses at sea; 
it does not itself provide for compliance with those other Federal 
laws.
    The Marine Mammal Protection Act (MMPA), for example, regulates 
human interactions with ``marine mammals''. The term marine mammal 
refers to any

[[Page 31999]]

mammal that is morphologically adapted to the marine environment 
(including sea otters and members of the orders Sirenia, Pinnipedi, and 
Cetacea) or primarily inhabits the marine environment (e.g., polar 
bears). The Marine Turtle Conservation Act defines a sea turtle using 
the term ``marine turtle'', which means any member of the taxonomic 
family Cheloniidae or Dermochelyidae.
    The EPA does not anticipate that the disposition of marine mammal 
or sea turtle carcasses will occur except in circumstances, such as but 
not limited to beached and floating marine mammal or sea turtle 
carcasses and/or mass strandings of marine mammals or sea turtles 
resulting in mortalities. In those circumstances, disposition into the 
ocean may be necessary to protect human health, for example, when other 
disposal options are not available.
    Before 2017, the EPA permitted the ocean disposal of cetacean 
(whales and related species) and pinniped (seals and related species) 
carcasses on a case-by-case basis, with MPRSA emergency permits. The 
EPA issued a general permit for the ocean disposal of marine mammal 
carcasses, which became effective in January 2017, to streamline MPRSA 
authorization and reduce burdens associated with case-by-case 
permitting. That general permit provided authorization from January 5, 
2017, through January 4, 2024. Under the MPRSA, general permits may be 
issued for a period no longer than seven years. By re-issuing the 
general permit, the general permit's authorization to transport marine 
mammal and sea turtle carcasses for the purpose of disposal and to 
dispose marine mammal and sea turtle carcasses in ocean waters would be 
available for another seven-year period. From January 5, 2017, through 
January 4, 2024, the effective period for the prior MPRSA general 
permit for ocean disposal of marine mammal carcasses, the EPA 
authorized 32 marine mammal carcass disposals in ocean waters under the 
general permit. During that same period of time, the EPA authorized an 
additional 43 marine mammal carcass disposals using emergency permits. 
Re-issuance of the general permit avoids the need for emergency 
permitting for marine mammal or sea turtle carcasses when such 
emergencies arise.
    Federal laws providing protection and conservation of marine 
mammals and sea turtles include the MMPA, the Endangered Species Act 
(ESA), the Marine Turtle Conservation Act, the Whaling Convention Act 
(WCA), the Fur Seal Act, and international conventions, including the 
Inter-American Convention for the Protection and Conservation of Sea 
Turtles, the International Convention for the Regulation of Whaling, 
which established the International Whaling Commission (IWC), and the 
Convention on International Trade in Endangered Species of Wild Fauna 
and Flora. Although this general permit applies only to marine mammal 
or sea turtle carcasses, certain international regulations are 
relevant. The United States is a party to the IWC and IWC regulations 
are self-implementing. The EPA is not the Federal agency charged with 
primary implementation of the United States' obligations under IWC 
regulations, but the MPRSA general permit is consistent with them.
    IWC regulations recognize indigenous or aboriginal subsistence 
whaling. As relevant to subsistence whaling in the United States, the 
IWC sets catch limits for the Western Arctic stock of bowhead whales 
and Eastern North Pacific gray whales based upon the needs of 
subsistence fishing in Alaska villages and subsistence needs of the 
Makah Indian Tribe, respectively. The bowhead whale hunt is managed 
cooperatively by the National Marine Fisheries Service (NMFS) and the 
Alaska Eskimo Whaling Commission under the WCA and the MMPA. The gray 
whale hunt is managed cooperatively by NMFS and the Makah Tribal 
Council under the WCA and under a waiver of the MMPA (50 CFR 216.100 
through 216.119). As such, any Alaska Native or member of the Makah 
Indian Tribe, who already may take a marine mammal under the MMPA and 
the ESA, is provided authority under this general permit should marine 
mammal carcasses need to be transported and disposed at sea. In re-
issuing this general permit the EPA does not intend to change, alter, 
or otherwise affect any ceremonial, cultural, religious and/or 
subsistence practices involving marine mammals or sea turtles.
    The other relevant Federal programs under the MMPA and the ESA are 
implemented by NMFS. MMHSRP Stranding Agreement Holders are provided 
authority to dispose of marine mammal carcasses in the ocean under this 
MPRSA general permit because Stranding Agreement Holders are authorized 
to take marine mammals subject to the provisions of the MMPA (16 U.S.C. 
1361 et seq.) and the Fur Seal Act of 1966, as amended (16 U.S.C. 1151 
et seq.). Members of the STSSN are provided authority to dispose of sea 
turtle carcasses under this MPRSA general permit because they are 
authorized to take sea turtles subject to the provisions of the ESA (16 
U.S.C. 1531 et seq.), individual ESA Section 10 permits and/or the 
implementing regulations governing the taking, importing, and exporting 
of endangered and threatened marine species and designated critical 
habitat (50 CFR parts 222 through 226). As such, MMHSRP Stranding 
Agreement Holders and/or authorized members of the STSSN may have a 
need for ocean disposal should stranded marine mammals or sea turtles 
die.

III. Hazard to Public Safety and Navigation

    A floating carcass near shore, for example, near a recreational 
beach or in a harbor or ship channel, may pose a risk to public safety 
before making land fall to the extent it might attract predators (e.g., 
sharks) to a recreation area or may pose a hazard to navigation. Per 
regulations promulgated by the U.S. Army Corps of Engineers (USACE), at 
33 CFR 245.20, the determination of a navigation hazard is made jointly 
by the USACE and the U.S. Coast Guard (USCG). If such a determination 
is made, the USACE determines appropriate remedial action as described 
in USACE regulations at 33 CFR 245.25, which may include carcass 
removal. MPRSA authorization to transport a carcass for the purpose of 
ocean disposal would be available through this MPRSA general permit if 
the navigation hazard removal operation requires ocean disposal of such 
carcasses.

IV. Strandings and Beachings

    Marine mammals and sea turtles that have died or have become sick 
or injured can reach the ocean shoreline by a variety of mechanisms. 
Possible mechanisms include: beaching, which involves a marine mammal 
or sea turtle carcass being driven ashore by currents or winds; 
stranding (single or multiple) of live marine mammal(s) or sea 
turtle(s) that subsequently die; and transport on the bow of vessels. 
In most stranding cases, the causes of marine mammal and sea turtle 
strandings are unknown, but some causes may include the following: 
disease, parasite infestation, harmful algal blooms, injuries due to 
ship strikes, fishery entanglements, pollution exposure, unusual 
weather or oceanographic events, trauma and starvation. While many 
marine mammals and sea turtles die every year, most carcasses never 
reach the shore; rather, the carcasses are consumed by other organisms 
or decompose sufficiently to sink to the ocean bottom where, depending 
upon size, the carcass may form the basis of an ``organic fall'' 
ecosystem.

[[Page 32000]]

    Stranding or beaching of marine mammals, sea turtles and/or marine 
mammal or sea turtle carcasses may pose a risk to public health due to 
the potential to transfer communicable diseases (e.g., brucellosis, 
poxvirus and mycobacteriosis) to the exposed public. Marine carcasses 
present a significant disposal concern not only because of their size 
but also due to the frequency with which carcasses reach the shoreline. 
From 2006--2021, an average of 6,300 marine mammals stranded on United 
States shorelines per year (NMFS, 2024). A large majority of marine 
mammals that strand either are dead or die shortly after stranding 
(NMFS, 2022).

V. Disposal and Management Options

    Generally, MMHSRP Stranding Agreement Holders and members of the 
STSSN are authorized to respond to marine mammals and sea turtles, 
respectively, that are found floating near shore or beached or stranded 
along the shore. While Stranding Agreement Holders and members of the 
STSSN do not and cannot respond to every stranded marine mammal and sea 
turtle, when they do respond and deem disposal necessary, the carcass 
must be disposed of properly. The MMHSRP has prepared a programmatic 
Environmental Impact Statement that describes, among other things, 
disposal and management options for carcasses of deceased marine 
mammals (NMFS, 2022).
    For a dead marine mammal or sea turtle encountered, generally 
available methods for carcass disposal and management fall into two 
main categories: remove-from-the-environment and remain-in-the-
environment. Remove-from-the-environment methods entail moving the 
carcass for disposal through controlled means and include disposing of 
a carcass in a landfill, or incinerating, rendering, or composting the 
carcass. Remain-in-the-environment methods involve leaving the marine 
mammal or sea turtle carcass in the environment to decompose naturally 
and include the following: allowing the carcass to remain and decompose 
in place; burying the carcass in place; and transporting the carcass to 
sea for ocean disposal. No single method is recommended for every 
carcass, and several factors are necessarily considered to determine 
the best disposal method for any particular carcass. Selection of a 
disposal method depends on factors such as number and size of the 
animals, carcass condition, the location, if chemicals were 
administered (including as antibiotics, sedatives and/or chemical 
euthanasia agents), availability of local resources and transportation 
logistics. Location considerations include coastal geography, currents, 
proximity to areas used extensively by the public, and Tribal, Federal, 
State, and/or local laws and regulations. While this Federal Register 
publication discusses other disposal methods briefly, the MPRSA general 
permit itself only concerns the disposal method to tow or otherwise 
transport the carcass of a marine mammal or sea turtle to sea for ocean 
disposal and the at-sea disposition of the remains.

A. Remove-from-the-Environment Methods

    One benefit of removing the carcass from the environment is 
minimizing the likelihood of infectious disease transmission to humans, 
domesticated animals and wildlife. These methods either sequester the 
carcass or destroy the carcass and any associated pathogens and should 
be considered if the animal is suspected to have died from a disease 
that can easily spread to human or other animal populations. Remove-
from-the-environment approaches can also be beneficial if the carcass 
contains toxic chemicals, such as certain chemical euthanasia agents, 
like pentobarbital. Some of these methods effectively remove these 
substances from the environment.
1. Disposal in a Licensed Landfill
    The most widespread remove-from-the-environment method is disposal 
in a landfill. With this method, the carcass is removed from the 
beaching or stranding location and brought to a nearby landfill in a 
lined or contained transport vehicle. Disposal in a licensed landfill 
can minimize the likelihood and adverse effect of releasing any toxic 
substances contained in the carcass, including any euthanasia drugs, 
because the substances can be contained to one location. However, not 
all licensed landfills may be able to accept animals that have been 
euthanized with barbiturates. Therefore, authorities would contact 
local landfills to ensure that the landfill can accept carcasses that 
contain these drugs.
2. Incineration
    Incineration is the process by which carcass tissues are 
disintegrated by burning. Incineration, particularly at an incineration 
facility, destroys the physical integrity of a carcass and the 
remaining ashes and hard parts (i.e., teeth, bones, etc.) are buried in 
a landfill. Disposal via incineration can prevent the spread of 
diseases, toxic materials and veterinary drugs contained in the carcass 
from entering the environment. Disposal via the incineration method may 
require preplanning and coordination with the local facility to fully 
understand the biological load that the incineration facility can 
manage. Incineration can be very expensive. Incineration facilities are 
not commonly found in all areas of the United States and the 
availability of commercial or municipal incinerators may be limited by 
the transportability of the carcass.
3. Rendering
    Rendering is an activity in which the carcass is rapidly reduced 
and recycled into new products. Rendering uses all parts of the animal 
and often creates a protein by-product (e.g., protein meal) and a fat 
by-product (e.g., tallow and grease). Disposal via rendering exposes 
the carcass to high heat to eliminate pathogens and prevent the spread 
of diseases. However, if a carcass contains euthanasia drugs some 
facilities may not be able to accept or process the carcasses depending 
on the drug. Disposal via rendering requires preplanning and 
coordination with the rendering facility to fully understand its 
policies for disposal of animals that were chemically euthanized. 
Rendering may be very expensive. Rendering facilities are not commonly 
found in all areas of the United States and the availability of 
rendering facilities may be limited by the transportability of the 
carcass.
4. Composting
    Composting marine mammal or sea turtle carcasses would involve 
bringing a carcass to a commercial composting facility (which may or 
may not require a State or local operating license) or to a site 
designated specifically for carcass composting or composting in a 
carcass digester. While composting is similar to disposal in a 
landfill, it offers the added benefit that the nutrients contained 
within the carcass are transformed into biologically available 
material. Disposal via composting can minimize the threat of releasing 
any pathogens or toxic substances contained in the carcass, including 
euthanasia drugs, because composted carcasses are contained to one 
location. However, if a carcass contains certain veterinary drugs, some 
facilities may not be able to accept or process the carcasses. Disposal 
via composting requires preplanning and coordination with the local 
facility to fully understand their policies for disposal of animals 
that were chemically euthanized and to ensure that all carcass compost 
will be used in accordance with local and State

[[Page 32001]]

regulations on wildlife compost. Composting facilities are not commonly 
found in all areas of the United States and the availability of 
composting facilities may be limited by the transportability of the 
carcass.

B. Remain-in-the-Environment Methods

    The remain-in-environment methods of disposal involve leaving 
marine mammal or sea turtle carcasses to naturally break down in the 
same, or similar, area in which it was found. Natural decomposition or 
burial in place may be used for both small and large marine mammal or 
sea turtle carcasses and is often the most preferred method if the 
carcass size or remoteness of the carcass location avoids logistical 
issues related to transportation. Remain-in-the-environment disposal 
methods should not be used for animals that were chemically euthanized 
with drugs known to cause secondary poisoning.
1. In-Place Decomposition
    Allowing a carcass to remain in place to decompose may be an 
acceptable disposal method if the carcass does not pose a human 
exposure risk for public health and animal health or result in 
unacceptable odor or visual aesthetic impacts. In-place decomposition 
may also be the most practical when the carcass is located in an area 
that is remote or inaccessible to heavy equipment, thereby making other 
options, such as burying in place or moving to a different disposal 
location, infeasible.
2. In-Place Burial
    In-place burial of a marine mammal or sea turtle carcass involves 
burying the carcass in the same or a similar location where the animal 
was found and may be used as a disposal method, especially when the 
carcass is located near population centers or near areas used for 
recreational activities. In-place burial involves excavating a trough 
above the high tide line, placing the carcass in the trench and 
covering the carcass with the excavated material. Burying the carcass 
creates a barrier that minimizes the smell and sight of the decaying 
carcass and reduces the likelihood of transmitting infectious diseases 
and attracting scavengers. Utilizing the in-place burial disposal 
method also depends on other factors such as the sediment substrate in 
the area (e.g., fine sediments versus rocks and boulders), the 
availability of appropriate excavation equipment, and ability to avoid 
potential environmental damage (e.g., destruction of dunes, beach 
grass, or nesting sites) caused by the transportation and operation of 
excavation equipment.
3. Ocean Disposal
    The ocean disposal method is the only method to which the MPRSA 
general permit applies and imposes requirements. If a carcass cannot be 
moved to a land-based disposal location, left above ground to decay, or 
be buried in-place, then it would be appropriate to tow (or transport 
offshore via another method) and dispose of the carcass in the ocean, 
provided that an acceptable ocean disposal ``site'' or location can be 
identified. Ocean disposal of a marine mammal or sea turtle carcass 
entails selection of an appropriate location for the carcass to be 
released or sunk to prevent the carcass from drifting or washing back 
onshore with all reasonable effort, becoming a hazard to navigation, or 
damaging protected and sensitive habitats. The carcass may float due to 
gas formation from decomposition. To facilitate rapid sinking, opening 
the body cavity may be necessary. If the carcass is to be sunk rather 
than released at the disposal site, appropriate carcass preparation may 
be necessary (e.g., piercing the body cavity, attaching weights, cement 
barriers or chains) at the ocean disposal site so that the carcass will 
not return to shore or pose a hazard to navigation.

VI. Potential Consequences of Marine Mammal and Sea Turtle Carcass 
Disposal in the Ocean and Why a General Permit Is Appropriate

    Leaving a marine mammal or sea turtle carcass in the environment to 
decompose, for example through in-place decomposition or burial or 
ocean disposal, provides a number of benefits to terrestrial, pelagic 
and benthic ecosystems (NMFS, 2022). Marine mammal and sea turtle 
carcasses that become stranded onshore and are left in-place to 
decompose or are buried are an integral part of coastal ecosystems 
providing a key source of food to scavengers and nutrients to the 
sediments, which may be used by algae and plants potentially increasing 
landscape heterogeneity (Bui 2009; Laidre et al., 2018; Quaggiotto et 
al., 2022; Schultz et al., 2022). Marine mammal and sea turtle 
carcasses that decompose while floating in ocean waters provide an 
energy-rich source of food for other marine animals, such as orcas and 
sharks (Leclerc et al., 2011; Quaggiotto et al., 2022; Schultz et al., 
2022; Tucker et al., 2019; Whitehead and Reeves, 2005). Most marine 
mammal and sea turtle carcasses sink to the seafloor and decompose 
naturally (Quaggiotto et al., 2022; Schultz et al., 2022). Whale 
carcasses are a significant source of carrion in the marine 
environment, representing a huge food supply to scavengers and 
decomposers (Smith and Baco, 2003).
    Whale falls, which occur naturally, are the most studied examples 
of marine mammal carcass decomposition on the seafloor (Smith et al., 
2015). Whale falls are sites of intense and lasting enrichment of 
organic material and sulfides on the seafloor which attract and sustain 
diverse communities of vertebrate and invertebrate scavengers 
(Quaggiotto et al., 2022). Most deep-sea benthic ecosystems are 
organic-carbon limited and, in many cases, are dependent upon organic 
matter from surface waters (Smith and Baco, 2003). A sunken carcass 
provides a large load of organic carbon to the seafloor and enhances 
the structural complexity of the seafloor, provides habitats for 
chemosynthetic organisms and results in the establishment of 
specialized biological assemblages (Smith and Baco, 2003; Oldach et 
al., 2022; Smith et al., 2015). Over 20 macrofaunal species are known 
to exclusively inhabit the microenvironment formed by large organic 
falls and over 30 other macrofaunal species are known to inhabit these 
sites (Smith and Baco, 2003). The deep-sea benthic ecosystem response 
to whale falls has been the subject of scientific study and several 
stages of succession have been observed in the assemblages (Smith and 
Baco, 2003).
    The duration of these stages of a whale fall varies greatly with 
carcass size, but generally occur as follows. The first stage is marked 
by the formation of bathyal scavenger assemblages that include 
hagfishes, sleeper sharks, crabs and amphipods. During the second 
stage, sediments surrounding the carcass, which have become enriched 
with organic carbon, become colonized by high densities of worms (e.g., 
Dorvilleidae, Chrysopetalidae). Once the consumption of soft tissue is 
complete, decomposition proceeds dominantly via anaerobic microbial 
digestion of bone lipids. The efflux of sulfides from the bones may, 
depending upon the size of the skeleton, provide for the formation of 
chemoautotrophic assemblages, which marks the third stage of 
succession. Chemoautotrophic assemblages typically consist of organisms 
such as heterotrophic bacteria, mussels, snails, worms, limpets and 
amphipods.
    Water and sediment quality in the area adjacent to the fall may be 
negatively affected by at-sea disposals of marine mammal carcasses 
because a carcass could release contaminants into

[[Page 32002]]

the water during decomposition (NMFS, 2022). Because contaminants would 
dilute rapidly in the water or break down over time in the tissues, the 
adverse impact would be minor and no different than what would happen 
naturally had the carcass sank to the seafloor and decomposed (NMFS, 
2022).
    The EPA has permitted numerous at-sea disposals of marine mammal 
carcasses under the MPRSA. In 2020, the EPA conducted biological, 
chemical and physical monitoring of a location offshore where several 
marine mammal carcasses had been sunk for disposal between 2009 and 
2020, with the most recent disposal occurring six months prior to 
monitoring. The purpose of the survey was to determine any adverse 
impacts the decomposing whales may have caused to the immediate benthic 
community and surrounding area. Monitoring results from a recently 
disposed humpback whale carcass revealed that the carcass was reduced 
to whale bones with minimal whale tissue remaining within six months 
and found no measurable impact on sediment quality parameters 
(including total organic carbon, grain size and polychlorinated 
biphenyl concentration) from decomposition.
    Less research is available regarding at-sea decomposition of sea 
turtle carcasses. When a sea turtle dies at sea, however, the carcass 
typically sinks until decomposition gases cause the body to bloat and 
float to the surface (Schultz et al., 2022). Partially submerged, sea 
turtle carcasses may drift as they are transported by winds and 
currents until it washes onshore or decomposes further and sinks to the 
seafloor (Santos et al., 2018). Once settled on the seafloor, sea 
turtle carcasses would decompose naturally (Schultz et al., 2022).
    The EPA seeks to minimize the adverse impacts to the marine 
environment from the materials used when necessary to sink carcasses 
through a coordination between the general permittee and the regional 
EPA MPRSA Coordinator. Environmentally benign materials that have been 
used for sinking marine mammal carcasses include sandbags, jute rope, 
concrete and steel cables. These materials do not cause adverse impacts 
on water or sediment quality or harm the marine environment (NMFS, 
2022). The small volume of sand used to sink carcasses does not cause 
an adverse effect on the seafloor substrate type. Burlap sandbags and 
jute rope (used to sink smaller carcasses), which are non-plastic 
materials that are biodegradable, do not persist in the marine 
environment or cause an ingestion hazard (Araya-Schmidt and Queirolo, 
2019; Rautenbach et al., 2024; Unsworth et al., 2019; Wang et al., 
2021; Zhang et al., 2015). When jute rope is used to tie sandbags to 
the animal, the shortest length possible is used to minimize the risk 
of entanglement by other marine organisms. Concrete keel blocks and 
steel cable used to sink larger carcasses are made from non-plastic, 
inert materials that are not anticipated to degrade the water quality 
of the seafloor or the water column (Melchers et al., 2022; Moffat et 
al., 2017; NMFS, 2022; Sun et al., 2022).
    Generally, marine mammal and sea turtle strandings represent a 
minimum measure of actual at-sea mortality based on scientific studies 
that estimate that stranding events represent only 10-20% of total 
mortalities in open ocean environments (Epperly et al., 1996; Hart et 
al., 2006; Santos et al., 2018). Considering the available scientific 
information on marine mammal and sea turtle strandings, marine mammal 
and sea turtle in situ decomposition and organic falls, the EPA finds 
that the potential adverse effects of ocean disposal of marine mammal 
or sea turtle carcasses under the MPRSA permit are minimal for the 
following reasons: (1) except in rare instances, most marine mammal or 
sea turtle carcasses would sink to and decompose on the ocean floor 
rather than wash ashore; (2) the formation of an organic fall is a 
naturally occurring phenomenon with no known adverse environmental 
impacts; (3) the materials used for sinking carcasses are chosen to 
minimize adverse environmental impacts; (4) the site selection for 
sinking carcasses requires consultation to avoid adverse environmental 
impacts; and (5) transporting a marine mammal or sea turtle carcass to 
sea for ocean disposal, when other disposal methods are not viable, 
presents a minimal perturbation to a naturally occurring phenomenon.
    The EPA's findings are consistent with the statutory considerations 
applicable to permit issuance under the MPRSA because: (1) the general 
permit requires consideration of the need for ocean disposal and 
consideration of land-based alternatives; (2) marine mammal and sea 
turtle carcass disposals will not cause a significant adverse effect on 
human health and welfare, fisheries resources, marine ecosystems, or 
alternate uses of the ocean; (3) marine mammal and sea turtle carcass 
disposals will not cause any persistent or permanent adverse effects; 
and (4) the release and disposal locations will be appropriately 
considered to protect human health and to minimize interference with 
navigation.

VII. Statutory and Regulatory Background

    MPRSA Section 101, 33 U.S.C. 1411, prohibits the unpermitted 
transportation of any material for the purpose of dumping it into ocean 
waters. MPRSA Section 102(a)(1), 33 U.S.C. 1412(a), authorizes the EPA, 
after notice and the opportunity for public hearings, to issue MPRSA 
permits. Section 102(a) of the MPRSA directs the EPA, in issuing a 
permit and/or evaluating a permit application, to consider, among other 
things, the need for ocean dumping as well as alternatives to ocean 
dumping. MPRSA Section 104(c), 33 U.S.C. 1414(c), authorizes the EPA to 
issue general permits for the transportation for the purpose of 
dumping, dumping, or both for specified materials, or classes of 
materials, it determines will have a minimal adverse environmental 
impact. The EPA regulations explain that the EPA may issue general 
permits for the dumping of materials that have a minimal adverse 
environmental impact and are generally disposed of in small quantities, 
or emergency permits for specific classes of materials that must be 
disposed of in emergency situations (40 CFR 220.3(a) and (c)). The 
towing or other method of transportation to move a marine mammal or sea 
turtle carcass offshore by any person for disposal at sea constitutes 
transportation of material for the purpose of dumping in ocean waters, 
and thus is subject to the MPRSA. Because the material to be disposed 
will consist of the carcass or carcasses, and in some cases 
environmentally benign material used to sink the carcass or carcasses, 
there will be no materials present that are prohibited by 40 CFR 227.5.

VIII. Consideration of Subsistence Uses Authorized Under the MMPA

    In re-issuing this general permit, the EPA attempts, to the maximum 
extent allowable, to avoid interference with long-standing subsistence 
uses and traditional cultural practice of Alaska natives and the Makah 
Indian Tribe engaged in ceremonial and subsistence practices. 
Recognition of subsistence uses is incorporated into the MMPA and the 
EPA derived permit terms for such users consistent with the MMPA's 
designed recognition of those uses. In re-issuing this general permit, 
the EPA does not intend to change, alter or otherwise affect 
subsistence uses of marine mammals by Alaska Natives and members of the 
Makah Indian Tribe.
    The general permit does not in any way require ocean disposal of 
marine mammal carcasses. Instead, the permit

[[Page 32003]]

merely provides the required Federal permit authorization of ocean 
disposal of marine mammal carcasses when there is a need for 
disposition of carcasses at sea. Subsistence activities of Alaska 
Natives and members of the Makah Indian Tribe that fall outside the 
scope of ocean disposition of carcasses may include: hunting, 
harvesting, salvaging, hauling, dressing, butchering, distribution, and 
consumption of marine mammals (or any other species used for 
subsistence purposes); the transportation and disposition of marine 
mammal carcasses at inland locations, such as in whale boneyards or in 
inland waters (i.e., waters that are landward of the baseline of the 
territorial sea, such as rivers, lakes, and certain enclosed bays or 
harbors); or leaving marine mammal carcasses to decompose in place, 
where there is no transportation by vessel or other vehicle for the 
purpose of ocean disposal. The purpose of this general permit is to 
expedite the required MPRSA permit authorizations the EPA manages for 
the ocean disposal of marine mammal carcasses.

A. Consideration of Alaska Natives Engaged in Subsistence Uses

    Alaska Natives engaged in subsistence uses are not required to, but 
may, transport and dispose of marine mammal carcasses in ocean waters. 
The EPA developed Section B of the general permit taking into 
consideration the subsistence use patterns and needs of Alaska Native 
persons. For purposes of this general permit, the EPA uses the term 
``Alaska Native'' with reference to the MMPA exemption specifically, 
the exemption for ``any Indian, Aleut, or Eskimo who resides in Alaska 
and who dwells on the coast of the North Pacific Ocean or the Arctic 
Ocean'' who takes a marine mammal ``for subsistence purposes'' or ``for 
purposes of creating and selling authentic native articles of 
handicrafts and clothing'' and provided such taking is not in a 
wasteful manner (16 U.S.C. 1371(b)).
    Section B of the general permit provides separate terms for 
authorized ocean disposal of marine mammal carcasses by an Alaska 
Native engaged in subsistence uses for two reasons. First, marine 
mammals are comparatively abundant and widely distributed throughout 
coastal Alaska, and Alaska Natives depend upon these natural resources 
for many customary and traditional uses. Collectively, the customary 
and traditional uses (e.g., food, clothing) are referred to as 
``subsistence uses.'' Alaska Natives have been using marine mammals for 
subsistence for thousands of years. The United States recognizes the 
importance of Alaska Native subsistence uses under the MMPA, which 
expressly exempts Alaska Natives engaged in subsistence uses from the 
general prohibition on ``taking'' marine mammals under certain 
circumstances (16 U.S.C. 1371(b)). The MPRSA, by comparison, does not 
include a similar exemption for the transport and disposal in ocean 
waters by Alaska Natives when marine mammal carcasses (or parts 
thereof) have no further use for subsistence purposes. Section B of the 
general permit accommodates the absence of an MPRSA exemption similar 
to the MMPA exemption by facilitating authorization of ocean disposal 
of marine mammal carcasses by Alaska Natives, including through annual 
rather than episodic reporting. Second, many coastal communities of 
Alaska Natives who engage in subsistence uses are located in remote 
locations and thus face a time-critical public safety issue, for 
example, when a marine mammal carcass washes ashore near a village or 
town, or a marine mammal is harvested or salvaged and the carcass is 
hauled ashore near a village or town. Such carcasses may attract bears 
or other scavenger animals, which may increase the risk of human injury 
or mortality. For these reasons, there are specific provisions in the 
general permit for Alaska Natives engaged in subsistence activities to 
expedite the transport and disposal of marine mammals in ocean waters, 
if necessary.
    With these considerations in mind, the EPA's re-issuance of the 
Alaska Native-specific permit conditions (see Section B) is intended, 
to the maximum extent allowable, to avoid unnecessary interference with 
long-standing subsistence uses and traditional cultural practices, and 
to recognize the unique circumstances of Alaska Natives engaged in 
subsistence uses. In re-issuing this general permit, the EPA does not 
intend to change, alter, or otherwise affect subsistence uses of marine 
mammals by Alaska Natives engaged in subsistence uses. Section B sets 
forth requirements designed to address these considerations while also 
complying with international treaties, the MPRSA, and the EPA's 
regulations at 40 CFR subchapter H. The primary differences between 
Sections A and B relate to Federal agency concurrence, distance from 
land requirements for ocean disposal, and reporting requirements.

B. Consideration of Members of the Makah Indian Tribe

    Members of the Makah Indian Tribe engaged in ceremonial and 
subsistence uses of marine mammals may, but are not required to, 
transport and dispose of marine mammal carcasses in ocean waters. For 
purposes of this general permit, Section C of the general permit 
authorizes ocean disposal of marine mammal carcasses by any member of 
the Makah Indian Tribe engaged in subsistence uses. The Makah Indian 
Reservation occupies a reservation located on the remote, northwestern 
tip of Washington State where the Strait of Juan de Fuca meets the 
Pacific Ocean. For thousands of years, the Makah Indian Tribe has 
depended on resources from the ocean for their subsistence, culture, 
and economy and hunting and harvesting whales, seals, other marine 
mammals, and marine fish have always been integral and essential to the 
Makah Indian Tribe.
    The United States recognizes the importance of ceremonial and 
subsistence uses of marine mammals by the Makah Indian Tribe through 
the Treaty of Neah Bay. Through the Treaty of Neah Bay, the United 
States recognizes sovereign rights of the Makah Indian Tribe to natural 
resources and cultural practices, including the right to hunt and 
harvest whales, seals, other marine mammals, and marine fish, as well 
as the Makah Indian Reservation. By regulation, the Secretary of 
Commerce has issued a conditional waiver from the MMPA moratorium on 
the take of Eastern North Pacific gray whales for enrolled members of 
the Makah Indian Tribe (50 CFR 216.10 through 216.119; 16 U.S.C. 
1371(a)(3)(A)). By comparison, the MPRSA does not provide the EPA with 
authority to waive permitting requirements for the transport and 
disposal in ocean waters when marine mammal carcasses (or parts 
thereof) have no further subsistence or ceremonial use. For reasons 
similar to the accommodations for Alaska Natives, the EPA includes 
Makah Indian Tribe-specific permit conditions (see Section C) to 
minimize interference with long-standing marine mammal subsistence uses 
and traditional cultural practices of the Makah Indian Tribe.
    Though EPA did not propose the Makah Indian Tribe-specific 
provisions, the inclusion of these provisions in this final general 
permit merely recognizes the existing MMPA waiver of the Eastern North 
Pacific gray whale moratorium applicable to the Makah Indian Tribe. The 
difference between Sections A and C (for the Makah Indian Tribe) 
relates to one aspect of prior consultation. Section C of the general 
permit does not require that members of the Makah Indian Tribe conduct 
prior consultation with a Stranding Agreement Holder for the disposal 
of

[[Page 32004]]

carcasses (or parts thereof) that have no further subsistence or 
ceremonial use. In addition, Section C includes conditions required as 
part of the Clean Water Act section 401 water quality certification 
process, as explained below, regardless of how unlikely it may be that 
a member of the Makah Indian Tribe might transport carcasses (or parts 
thereof) to the waters where those additional conditions apply.

IX. Discussion

    Considering the information presented in the previous sections, the 
EPA determines that the potential adverse environmental impacts of 
marine mammal or sea turtle carcass disposals at sea, in compliance 
with the permit's terms, are minimal and that marine mammal and sea 
turtle carcasses often must be disposed of to mitigate threats to 
public safety (e.g., recreational uses in nearby waters) as well as 
risks of navigation hazards. As such, issuance of a general permit for 
the transportation for the purpose of disposal and the ocean disposal 
of marine mammal and sea turtle carcasses is appropriate under the 
MPRSA.
    Authorization under Section A of the general permit is available to 
Tribal, Federal, State, and local government officials and employees 
acting in the course of official duties and to MMHSRP Stranding 
Agreement Holders and members of the STSSN. Section A authorizes such 
persons to transport and dispose of marine mammal or sea turtle 
carcasses in ocean waters. Section A requires that each such permittee 
consult with the MMHSRP of NMFS or the STSSN--and recommends that each 
such general permittee consults with the applicable USCG District 
Office--prior to initiating any ocean disposal activities with respect 
to a marine mammal or sea turtle carcass. Permittees authorized under 
Section A would need to consult with and obtain concurrence from the 
applicable EPA Regional Office on selection of an ocean disposal site, 
which must be at a location three miles seaward of the mean lower low 
water line (ordinary low water mark) along the coast or a ``closing 
line'' across river mouths and openings of bays as demarcated on 
nautical charts. Disposal sites in the ocean waters of Puget Sound are 
not subject to the distance-from-shore restriction; however, permittees 
would need to consult with and obtain concurrence from EPA Region 10 on 
selection of the site. The EPA requested certification under Clean 
Water Act section 401 that discharges under this permit will comply 
with applicable provisions of Clean Water Act sections 301, 302, 306 
and 307 from the State of Washington and from Tribes in the Puget Sound 
area for disposals in the ocean waters of Puget Sound that are not 
subject to the permit's distance-from-shore restriction. Only one 
entity, the Port Gamble S'Klallam Tribe, required additional conditions 
as part of the certification process, and those conditions are included 
in the permit. All permittees authorized under Section A also need to 
submit a report to the applicable EPA Regional Office on the ocean 
disposal activities after the disposal.
    Alaska Natives engaged in subsistence uses are not required to, but 
may, transport and dispose of marine mammal carcasses in ocean waters. 
When disposal in ocean waters is the selected disposal approach, 
Section B of the general permit authorizes any Alaska Native engaged in 
subsistence uses to transport and dispose of a marine mammal carcass in 
ocean waters. Under Section B, the Alaska Native general permittee 
selects an ocean disposal site sufficiently far offshore so that 
currents and winds are not expected to return the carcass to shore, and 
the carcass is not expected to pose a hazard to navigation and 
afterwards submits, on an annual basis, a report to EPA Region 10 on 
ocean disposal activities conducted in the prior calendar year. Section 
B does not require a statement of need for selecting ocean disposal nor 
does it specify a distance requirement. The EPA requested certification 
under Clean Water Act section 401 that discharges under Section B of 
this permit will comply with applicable provisions of Clean Water Act 
Sections 301, 302, 306 and 307 from the State of Alaska for disposals 
in ocean waters by any Alaska Native at any distance from shore. The 
State of Alaska certified discharges associated with this general 
permit under Clean Water Act section 401 without additional conditions.

X. Response to Comments Received

    The EPA published notice of the proposed re-issuance of the general 
permit on October 8, 2024, and invited public comment for a 60-day 
period that concluded on December 9, 2024. The EPA received four 
comment letters from private citizens, a non-governmental organization 
and an Alaska Native Village. All comments received supported re-
issuance of this general permit and agreed with the EPA's assessment 
that the activities would not result in long-lasting adverse impacts. 
The EPA has developed a Response to Comments documents explaining the 
EPA's consideration of public comments received during the comment 
period. In response to the comments received, the EPA modified the 
final permit with expansions in the scope of eligibility and 
clarifications, including to improved language clarity and 
organization.

XI. Statutory and Executive Order Reviews

A. Paperwork Reduction Act

    The information collections under this general permit are covered 
under the MPRSA Information Collection Request (ICR) that has been 
approved by the Office of Management and Budget (OMB) under the 
Paperwork Reduction Act. The ICR document that the EPA prepared for all 
MPRSA activities has been assigned EPA ICR number 0824.08.
    Under section 104(e) of the MPRSA, 33 U.S.C. 1414(e) and 
implementing regulations at 40 CFR 221.1 and 221.2, applicants for an 
MPRSA permit must provide information that the EPA determines is 
necessary to review and evaluate such application, for example, to 
ensure that ocean dumping is appropriately regulated and will not harm 
human health or the marine environment. To meet United States' 
reporting obligation under the London Convention, the EPA reports some 
of this information in the annual United States ocean dumping report, 
which is transmitted to the International Maritime Organization for 
treaty compliance purposes.
    Respondents/affected entities: Any officer, employee, agent, 
department, agency, or instrumentality of Tribal, Federal, State, or 
local unit of government, as well as any MMHSRP Stranding Agreement 
Holder and/or authorized member of the STSSN, who disposes of a marine 
mammal or sea turtle carcass in ocean waters and any Alaska Natives or 
members of the Makah Indian Tribe engaged in subsistence uses who 
disposes of a marine mammal carcass in ocean waters will be affected by 
this general permit. Under this general permit, respondents do not need 
to request permit authorization because the general permit authorizes 
ocean disposal of a marine mammal or sea turtle carcass by an eligible 
person.
    Respondent's obligation to respond: Pursuant to regulations 
implementing section 104(e) of the MPRSA, 33 U.S.C. 1414(e), at 40 CFR 
221.1 through 221.2, the EPA requires all ocean dumping permittees to 
supply specified reporting information.

[[Page 32005]]

B. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This MPRSA permitting action has Tribal implications, but the 
general permit will neither impose substantial direct compliance costs 
on federally recognized Tribal governments, nor preempt Tribal law. The 
general permit has Tribal implications because it may affect 
traditional practices of some Tribes.
    The EPA consulted with Tribal officials under the EPA Policy on 
Consultation and Coordination with Indian Tribes early in the process 
of reviewing the previous general permit and preparing to re-issue this 
general permit to allow them to have meaningful and timely input into 
its development.
    On February 14, 2023, the EPA emailed a consultation notification 
letter with a consultation and coordination plan to all 574 federally 
recognized Tribes, notifying them of this upcoming action and inviting 
Tribal leaders and designated consultation representatives to 
participate in the Tribal consultation and coordination process.
    In early 2024, when the EPA was considering expanding the scope of 
the general permit to include ocean waters of Puget Sound, it held an 
additional Tribal coordination and consultation period for the Tribes 
in the Puget Sound area that could be affected by any such expansion of 
the permit's scope.
    On April 2, 2024, the EPA emailed a consultation notification 
letter with a consultation and coordination plan to federally 
recognized Tribes in the Puget Sound area, notifying the Tribes of the 
proposal to modify the scope of the permit, and inviting Tribal leaders 
and designated consultation representatives to participate in the 
Tribal consultation and coordination process. A summary of the Tribal 
consultation and coordination effort, the Tribal input received, and 
how the EPA considered the input received may be found in the docket 
for this action (Docket ID No. EPA-HQ-OW-2023-0329).

    For the reasons stated above, the EPA re-issues the general permit 
for the transportation and ocean disposal of marine mammal and sea 
turtle carcasses as follows:

General Permit for the Transportation and Ocean Disposal of Marine 
Mammal and Sea Turtle Carcasses

A. General Requirements for Governmental Entities and Stranding 
Agreement Holders

    Except as provided in Sections B and C below, any officer, 
employee, agent, department, agency, or instrumentality of Tribal, 
Federal, State, or local unit of government, any Marine Mammal Health 
and Stranding Response Program Stranding Agreement Holder, and any 
authorized member of the Sea Turtle Stranding and Salvage Network who 
already may take a marine mammal or sea turtle under the Endangered 
Species Act or Marine Mammal Protection Act, is hereby granted a 
general permit to transport for the purpose of disposal and dispose of 
marine mammal and sea turtle carcasses in ocean waters subject to the 
following conditions:
    1. The permittee shall consult with a Stranding Agreement Holder of 
the National Marine Fisheries Service or an authorized member of the 
Sea Turtle Stranding and Salvage Network prior to initiating any 
disposal activities, unless the permittee is an Agreement Holder or 
Network member, respectively. Points of contact for Stranding Agreement 
Holders and members of the Sea Turtle Stranding and Salvage Network are 
available at https://www.epa.gov/marine-protection-permitting/ocean-disposal-marine-mammal-and-sea-turtle-carcasses.
    2. The permittee shall consult with and obtain written concurrence 
(via email or letter) from the applicable EPA Regional Office on ocean 
disposal site selection. A disposal site must be at a location three 
miles seaward of the mean lower low water line (ordinary low water 
mark) along the coast or ``closing lines'' across river mouths and 
openings of bays as demarcated on nautical charts. Disposal sites in 
the ocean waters of Puget Sound are not subject to the distance-from-
shore restrictions, however permittees would need to consult with and 
obtain concurrence from EPA Region 10 on selection of the site. Because 
the presence of a marine mammal or sea turtle carcass near human 
habitation or recreation areas may pose a time-critical public safety 
issue, the permittee may obtain concurrence via telephone from the 
applicable EPA Regional Office provided that the permittee subsequently 
obtains written concurrence (via email or letter). Points of contact at 
the EPA are available at https://www.epa.gov/marine-protection-permitting/ocean-disposal-marine-mammal-and-sea-turtle-carcasses.
    3. If a determination is made that the carcass must be sunk, rather 
than released at the disposal site, the transportation and disposal of 
materials necessary to ensure the sinking of the carcass are also 
authorized for ocean dumping under this general permit. When materials 
are to be used to sink the carcass, the permittee must first consult 
with and obtain written concurrence (via email or letter) from the 
applicable EPA Regional Office on the selection of materials. Any 
materials described in 40 CFR 227.5 (prohibited materials) or 40 CFR 
227.6 (constituents prohibited as other than trace amounts) shall not 
be used. The transportation and dumping of any materials other than the 
materials necessary to ensure the sinking of the carcass are not 
authorized under this general permit and constitute a violation of the 
MPRSA. Because the presence of a marine mammal or sea turtle carcass 
near human habitation or recreation areas may pose a time-critical 
public safety issue, the permittee may obtain concurrence via telephone

B. Requirements for Any Alaska Native Engaged in Subsistence Uses

    Notwithstanding Section A, any Alaska Native engaged in subsistence 
uses is hereby granted a general permit to transport for the purpose of 
disposal and dispose of marine mammal carcasses in ocean waters subject 
to the following conditions:
    1. The permittee shall submit a report (via email or letter) on all 
disposal activities authorized by this general permit that the 
permittee has conducted in the prior calendar year. Reports shall be 
submitted to EPA Region 10 within 30 days of the end of the calendar 
year. Contact information for EPA Region 10 is available at https://www.epa.gov/marine-protection-permitting/ocean-disposal-marine-mammal-and-sea-turtle-carcasses. This report shall include:
    a. The number and type of carcasses disposed;
    b. A description of the general vicinity in which the carcasses 
were disposed; and
    c. The name and contact information of the permittee.
    2. Where ocean disposal is the selected approach, marine mammal

[[Page 32007]]

carcasses must be towed or otherwise transported to a site offshore 
where, based on available information, which may include local or 
traditional knowledge, currents and winds are not expected to return 
the carcass to shore and the carcass is not expected to pose a hazard 
to navigation.

C. Requirements for Any Member of the Makah Indian Tribe Engaged in 
Subsistence Uses

    Notwithstanding Section A, any member of the Makah Indian Tribe who 
already may take a marine mammal under the Endangered Species Act and 
the Marine Mammal Protection Act is hereby granted a general permit to 
transport for the purpose of disposal and dispose of marine mammal 
carcasses in ocean waters subject to the following conditions:
    1. The permittee shall consult with and obtain written concurrence 
(via email or letter) from the EPA Region 10 Office on ocean disposal 
site selection. A disposal site must be at a location three miles 
seaward of the mean lower low water line (ordinary low water mark) 
along the coast or ``closing lines'' across river mouths and openings 
of bays as demarcated on nautical charts. Disposal sites in the ocean 
waters of Puget Sound are not subject to the distance-from-shore 
restrictions, however permittees would need to consult with and obtain 
concurrence from EPA Region 10 on selection of the site. The permittee 
may obtain concurrence via telephone from the EPA Region 10 Office 
provided that the permittee subsequently obtains written concurrence 
(via email or letter). Points of contact at the EPA are available at 
https://www.epa.gov/marine-protection-permitting/ocean-disposal-marine-mammal-and-sea-turtle-carcasses.
    2. If a determination is made that the carcass must be sunk, rather 
than released at the disposal site, the transportation and disposal of 
materials necessary to ensure the sinking of the carcass are also 
authorized for ocean dumping under this general permit. When materials 
are to be used to sink the carcass, the permittee must first consult 
with and obtain written concurrence (via email or letter) from the EPA 
Region 10 Office on the selection of materials. Any materials described 
in 40 CFR 227.5 (prohibited materials) or 40 CFR 227.6 (constituents 
prohibited as other than trace amounts) shall not be used. The 
transportation and dumping of any materials other than the materials 
necessary to ensure the sinking of the carcass are not authorized under 
this general permit and constitute a violation of the MPRSA. The 
permittee may obtain concurrence via telephone from the EPA Region 10 
Office provided that the permittee subsequently obtains written 
concurrence (via email or letter).
    3. The permittee shall submit a report on the ocean disposal 
activities authorized by this general permit to the EPA Region 10 
Office within 30 days after carcass disposal. This report shall 
include:
    a. A description of the carcass(es) disposed (e.g., species, 
approximate length, general condition, floating or not);
    b. The date and time of the disposal, the latitude and longitude of 
the ocean disposal site, and the geodetic datum associated with the 
coordinates of the disposal site. Latitude and longitude of the 
disposal site shall be reported at the highest degree of accuracy 
available on board the vessel that transported the carcass (e.g., 
onboard geographic position system technology);
    c. The name, title, affiliation, and contact information of the 
person in charge of the disposal operation and the person in charge of 
the vessel or vehicle that transported the carcass (if different than 
the person in charge of the disposal); and
    d. A statement of need and rationale for selecting ocean disposal 
rather than other disposal options.
    4. The permittee shall immediately notify the EPA of any violation 
of any condition of this general permit.
    5. Additional permit conditions as required by the Port Gamble 
S'Klallam Tribe's Clean Water Act Section 401 certification for 
transportation and disposal of marine mammal and sea turtle carcasses 
waters within the boundaries of the Port Gamble S'Klallam Reservation 
and trust lands:
    a. Entities covered under this general permit shall use best 
management practices for sediment and turbidity control.
    b. No discharge covered under the general permit shall cause 
exceedances of port Gamble S'Klallam Surface Water Quality Standards 
narrative or number criteria.
    c. No carcasses shall be disposed of near shellfish beds used by 
Tribal fishers.
    d. No activities under this general permit may negatively impact 
Tribal resources.
    e. The Natural Resources Department shall be notified within 24 
hours of any accidents, equipment failures, or unexpected impacts 
resulting from activities associated with this general permit.
