Uniform National Discharge Standards for Vessels of the Armed
Forces--Phase II Batch Two

AGENCY: Environmental Protection Agency and Department of Defense.

ACTION: Final rule.

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

SUMMARY: The U.S. Environmental Protection Agency (EPA) and the U.S.
Department of Defense (DoD) are promulgating discharge performance
standards for 11 discharges incidental to the normal operation of a
vessel of the Armed Forces in the navigable waters of the United
States, the territorial seas, and the contiguous zone. When
implemented, the discharge performance standards will reduce the
adverse environmental impacts associated with the vessel discharges,
stimulate the development of improved vessel pollution control devices,
and advance the development of environmentally sound vessels of the
Armed Forces. The 11 discharges addressed by the final rule include the
following: Catapult water brake tank and post-launch retraction
exhaust, controllable pitch propeller hydraulic fluid, deck runoff,
firemain systems, graywater, hull coating leachate, motor gasoline and
compensating discharge, sonar dome discharge, submarine bilgewater,
surface vessel bilgewater/oil-water separator effluent, and underwater
ship husbandry.

DATES: This final rule is effective on August 17, 2020.

ADDRESSES: The EPA has established a docket for this action under
Docket No. EPA-HQ-OW-2016-0351. All documents in the docket are listed
on the http://regulations.gov website. The complete public record for
this rulemaking, including responses to comments received during the
rulemaking, can be found under Docket No. EPA-HQ-OW-2016-0351.

I. General Information

A. Legal Authority for the Final Rule

    The EPA and DoD promulgate this rule under the authority of Clean
Water Act (CWA) Section 312(n) (33 U.S.C. 1322(n)). Section 325 of the
National Defense Authorization Act of 1996 (NDAA), titled ``Discharges
from Vessels of the Armed Forces'' (Pub. L. 104-106, 110 Stat. 254),
amended CWA Section 312, to require the Administrator of the U.S.
Environmental Protection Agency (Administrator) and the Secretary of
Defense of the U.S. Department of Defense (Secretary) to develop
uniform national standards to control certain discharges incidental to
the normal operation of a vessel of the Armed Forces. The term Uniform
National Discharge Standards, or UNDS, is used in this preamble to
refer to the provisions in CWA Section 312(a)(12) through (14) and (n)
(33 U.S.C. 1322(a)(12) through (14) & (n)).

B. Purpose of the Final Rule

    The purpose of the statutory amendment for the establishment of the
UNDS rules is to enhance the operational flexibility of vessels of the
Armed Forces domestically and internationally, stimulate the
development of innovative vessel pollution control technology, and
advance the development of environmentally sound ships. Section
312(n)(3)(A) of the CWA requires the EPA and DoD to promulgate uniform
national discharge standards for certain discharges incidental to the
normal operation of a vessel of the Armed Forces (CWA Section
312(a)(12)), unless the Secretary finds that compliance with UNDS would
not be in the national security interests of the United States (CWA
Section 312(n)(1)).
    The final rule establishes discharge ``performance standards'' for
11 discharges incidental to the normal operation of a vessel of the
Armed Forces from among the 25 discharges for which the EPA and DoD
previously determined (64 FR 25126, May 10, 1999) that it is reasonable
and practicable to require a marine pollution control device (MPCD).
The 11 discharges addressed in the rule include the following: catapult
water brake tank and post-launch retraction exhaust, controllable pitch
propeller hydraulic fluid, deck runoff, firemain systems, graywater,
hull coating leachate, motor gasoline and compensating discharge, sonar
dome discharge, submarine bilgewater, surface vessel bilgewater/oil-
water separator effluent, and underwater ship husbandry. However, the
discharge performance standards do not become enforceable until after
promulgation of regulations by DoD under CWA Section 312(n)(5)(C) to
govern the design, construction, installation, and use of a MPCD. CWA
Section 312(n)(5)(C) requires DoD to promulgate the regulations as soon
as practicable after the promulgation of the discharge performance
standards, but not later than one year. Additionally, upon the
effective date of regulations by DoD under CWA Section 312(n)(5)(C),
CWA Section 312(n)(6)(A) provides that neither a state nor a political
subdivision of a state may adopt or enforce any statute or regulation
of the state (or the political subdivision) with respect to the
discharge or design, construction, installation or use of any MPCD
required to control discharges from a vessel of the Armed Forces.

C. What vessels are regulated by the final rule?

    The final rule applies to vessels of the Armed Forces. For the
purposes of the rulemaking, the term ``vessel of the Armed Forces'' is
defined at CWA Section 312(a)(14). Vessel of the Armed Forces means any
vessel owned or operated by the U.S. Department of Defense (i.e., U.S.
Navy, Military Sealift Command, U.S. Marine Corps, U.S. Army, and U.S.
Air Force), other than a time- or voyage-chartered vessel, as well as
any U.S. Coast Guard vessel designated by the Secretary of the
Department in which the U.S. Coast Guard is operating. The preceding
list of vessels is not intended to be exhaustive, but rather provides a
guide for the reader regarding the vessels of the Armed Forces to be
regulated by the final rule. The final rule does not apply to
commercial vessels; private vessels; vessels owned or operated by
state, local, or tribal governments; vessels under the jurisdiction of
the U.S. Army Corps of Engineers; certain vessels under the
jurisdiction of the U.S. Department of Transportation; vessels
preserved as memorials and museums; vessels under construction; vessels
in drydock; amphibious vehicles; and, as noted above, time- or voyage-
chartered vessels. For answers to questions regarding the applicability
of this action to a particular vessel, consult one of the contacts
listed in the FOR FURTHER INFORMATION CONTACT section.

D. What is the geographic scope of the final rule?

    The final rule is applicable to discharges from a vessel of the
Armed Forces operating in the navigable waters of the United States,
including the territorial seas, and the contiguous zone (CWA Section
312(n)(8)(A)). The final rule applies in both fresh and marine waters
and can include bodies of water such as rivers, lakes, and oceans. The
preamble refers to these waters collectively as ``waters subject to
UNDS.''
    Sections 502(7), 502(8), and 502(9) of the CWA define the terms
``navigable waters,'' ``territorial seas,'' and ``contiguous zone,''
respectively. The term ``navigable waters'' means waters of the United
States including the territorial seas, and the ``United States''
includes the States, the District of Columbia, the Commonwealth of
Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, the
Commonwealth of the Northern Mariana Islands, and the Trust Territories
of the Pacific Islands. The term ``territorial seas'' means the belt of
seas that extends three miles seaward from the line of ordinary low
water along the portion of the coast in direct contact with the open
sea and the line marking the seaward limit of inland waters. The term
``contiguous zone'' means the entire zone established or to be
established by the United States under Article 24 of the Convention of
the Territorial Sea and the Contiguous Zone. The contiguous zone
extends seaward twelve miles from the baseline from which the breadth
of the territorial sea is measured. The final rule is not applicable
seaward of the contiguous zone.

E. Rulemaking Process

    The UNDS rulemaking is a three-phase, joint rulemaking between the
EPA and DoD. The first two phases are joint rulemakings between the EPA
and DoD; the third phase is a DoD-only rulemaking.
Phase I
    The EPA and DoD promulgated Phase I regulations on May 10, 1999 (64
FR 25126), and these existing regulations are codified at 40 CFR part
1700. During Phase I, the EPA and DoD identified the discharges
incidental to the normal operation of a vessel of the Armed Forces for
which it is reasonable and practicable to require control with a MPCD
to mitigate potential adverse impacts on the marine environment (CWA
Section 312(n)(2)), as well as those discharges for which it is not.
Section 312(a)(13) of the CWA defines a MPCD as any equipment or
management practice, for installation or use on a vessel of the Armed
Forces, that is designed to receive, retain, treat, control, or
discharge a discharge incidental to the normal operation of a vessel;
and that is determined by the Administrator and the Secretary to be the
most effective equipment or management practice to reduce the
environmental impacts of the discharge consistent with the
considerations set forth by UNDS.
    During Phase I, the EPA and DoD also identified the vessels with
discharges to be regulated under UNDS. The Phase I Technical
Development Document describes the range of vessels covered by UNDS
which includes both active and inactive vessels. Inactive vessels are
vessels owned by the Armed Forces that are not in operational status
but are retained as mobilization assets or held in long-term storage
for some other permanent disposition. The vessels are owned by the DoD,
pending final disposition and as such are covered under UNDS.
    The Phase I Technical Development Document also describes the 25

discharges that the EPA and DoD identified as requiring control with a
MPCD and the 14 discharges that do not require control. The 25
discharges requiring control include: Aqueous film-forming foam;
catapult water brake tank and post-launch retraction exhaust; chain
locker effluent; clean ballast; compensated fuel ballast; controllable
pitch propeller hydraulic fluid; deck runoff; dirty ballast;
distillation and reverse osmosis brine; elevator pit effluent; firemain
systems; gas turbine water wash; graywater; hull coating leachate;
motor gasoline and compensating discharge; non-oily machinery
wastewater; photographic laboratory drains; seawater cooling overboard
discharge; seawater piping biofouling prevention; small boat engine wet
exhaust; sonar dome discharge; submarine bilgewater; surface vessel
bilgewater/oil-water separator effluent; underwater ship husbandry; and
welldeck discharges (40 CFR 1700.4). The 14 discharges that do not
require control with a MPCD include: Boiler blowdown; catapult wet
accumulator discharge; cathodic protection; freshwater layup; mine
countermeasures equipment lubrication; portable damage control drain
pump discharge; portable damage control drain pump wet exhaust;
refrigeration/air conditioning condensate; rudder bearing lubrication;
steam condensate; stern tube seals and underwater bearing lubrication;
submarine acoustic countermeasures launcher discharge; submarine
emergency diesel engine wet exhaust; and submarine outboard equipment
grease and external hydraulics.
    As of the effective date of the Phase I rule (June 9, 1999), states
and political subdivisions of states are preempted from adoption or
enforcement of any state or local statutes or regulations with respect
to the 14 discharges that were identified as not requiring control,
except as provided for in no-discharge zones (CWA Sections 312(n)(6)(A)
and 312(n)(7)). In addition, CWA Section 312(n)(5)(D) authorizes the
governor of any state to submit a petition to the EPA and DoD
requesting the re-evaluation of a prior determination that a MPCD is
required for a particular discharge (40 CFR 1700.4) or that a MPCD is
not required for a particular discharge (40 CFR 1700.5), if there is
significant new information not considered previously, that could
reasonably result in a change to the determination (CWA Section
312(n)(5)(D) and 40 CFR 1700.11).
Phase II
    Section 312(n)(3) of the CWA requires the EPA and DoD to develop
discharge performance standards for each of the 25 discharges
identified in Phase I as requiring control. Development of the
discharge performance standards required the EPA and DoD to consult
with the Department in which the U.S. Coast Guard is operating, the
Secretary of Commerce, interested states, the Secretary of State, and
other interested federal agencies. CWA Section 312(n)(2)(B) directs the
EPA and DoD to consider seven factors when promulgating the Phase II
discharge performance standards: The nature of the discharge; the
environmental effects of the discharge; the practicability of using the
MPCD; the effect that installation or use of the MPCD would have on the
operation or the operational capability of the vessel; applicable U.S.
law; applicable international standards; and the economic costs of
installation and use of the MPCD. Section 312(n)(3)(C) of the CWA
authorizes the EPA and DoD to establish discharge standards that (1)
distinguish among classes, types, and sizes of vessels; (2) distinguish
between new and existing vessels; and (3) provide for a waiver of
applicability of standards as necessary or appropriate to a particular
class, type, age, or size of vessel.
    The EPA and DoD developed a process to establish the Phase II
discharge performance standards in three ``batches'' through three
separate rulemakings. The first batch of discharge performance
standards was published on January 11, 2017 (82 FR 3173), and addressed
11 of the 25 discharges identified as requiring control in Phase I. The
second batch of discharge performance standards, the subject of this
final rule, addresses an additional 11 discharges previously identified
as requiring control. The EPA and DoD are preparing the third batch of
performance standards to address the remaining three discharges
(relating to different variations of ballast water systems), which will
be proposed later.
    In developing the Phase II discharge performance standards, the EPA
and DoD referenced the 2013 National Pollutant Discharge Elimination
System (NPDES) Vessel General Permit (VGP) (78 FR 21938, April 12,
2013) and the 2014 NPDES Small Vessel General Permit (sVGP) (79 FR
53702, September 10, 2014) (hereafter referred to collectively as the
NPDES VGPs) as a baseline for each comparable discharge incidental to
the normal operation of a vessel of the Armed Forces. Geographically,
the NPDES VGPs applied seaward only to the CWA's three-mile territorial
sea and only to discharges incidental to the normal operation of non-
military and non-recreational vessels. The NPDES VGPs included effluent
limits that are based on both the technology available to treat
pollutants (i.e., technology-based effluent limitations), and limits
intended to be protective of the designated uses of the receiving
waters (i.e., water quality-based effluent limits), including both non-
numeric and numeric limitations. Using the NPDES VGPs as a ``reasonable
and practicable'' baseline to develop performance standards for
discharges incidental to the normal operation of a vessel of the Armed
Forces allowed the EPA and DoD to maximize the use of the EPA's
scientific and technical work developed to support the NPDES VGPs. The
NPDES VGPs technology-based and water quality-based effluent
limitations were then adapted, as appropriate, for the relevant
discharges from vessels of the Armed Forces. Additional information on
NPDES permitting can be found on-line at http://www.epa.gov/npdes/.
Phase III
    CWA Section 312(n)(4) requires DoD within one year of finalization
of Phase II and in consultation with the EPA and the Secretary of the
Department in which the U.S. Coast Guard is operating, to promulgate
Phase III UNDS regulations governing the design, construction,
installation, and use of MPCDs necessary to meet the Phase II discharge
performance standards. DoD will implement the Phase III regulations
under the authority of the Secretary as a DoD publication. The Phase
III regulations will be publicly released and are expected to be made
available on the Defense Technical Information Center website: http://www.dtic.mil/whs/directives. Similar to Phase II, Phase III will be
promulgated in three batches.
    Following the effective date of regulations under Phase III, it
will be unlawful for a vessel of the Armed Forces to operate within
waters subject to UNDS if the vessel is not equipped with a MPCD that
meets the final Phase II discharge performance standards (CWA Section
312(n)(8)). It also will be unlawful for a vessel of the Armed Forces
to discharge a regulated UNDS discharge into an UNDS no-discharge zone
(i.e., waters where a prohibition on a discharge has been established)
(CWA Section 312(n)(8)). Any person in violation of this requirement
shall be liable to a civil penalty of not more than $5,000 for each
violation (CWA Section 312(j)). The Secretary of the Department in
which the U.S. Coast Guard is operating enforces these provisions and
may utilize law enforcement officers, EPA personnel and facilities,
other

federal agencies, or the states to carry out these provisions. States
may also enforce these provisions (CWA Sections 312(k) and (n)(9)).
    In addition, as of the effective date of the Phase III regulations,
neither a state nor political subdivision of a state may adopt or
enforce any state or local statute or regulation with respect to
discharges identified as requiring control, except to establish no-
discharge zones (CWA Section 312(n)(7)). If a state determines that the
protection and enhancement of the quality of some or all of its waters
require greater environmental protection, the state may prohibit one or
more discharges incidental to the normal operation of a vessel of the
Armed Forces, whether treated or not, into those waters. CWA Section
312(n)(7) provides for the establishment of no-discharge zones and the
Phase I UNDS regulations established the criteria and procedures for
establishing no-discharge zones (40 CFR 1700.9 and 40 CFR 1700.10).
    The statute also requires the EPA and DoD to review the UNDS
determinations and standards every five years and, if necessary, to
revise them based on significant new information. Specifically, CWA
Sections 312(n)(5)(A) and (B) contain provisions for reviewing and
modifying both of the following determinations: (1) Whether control
should be required for a particular discharge, and (2) the substantive
standard of performance for a discharge for which control is required.
A governor also may petition the Administrator and the Secretary to
review a UNDS determination or standard if there is significant new
information, not considered previously, that could reasonably result in
a change to the determination or standard (CWA Section 312(n)(5)(D) &
40 CFR 1700.11).

F. Summary of Public Outreach and Consultation With Federal Agencies,
States, Territories, and Tribes

    During the development of the proposed rule and the final rule, the
EPA and DoD consulted with other federal agencies, states, and tribes
regarding the reduction of adverse environmental impacts associated
with discharges from vessels of the Armed Forces; development of
innovative vessel pollution control technology; and advancement of
environmentally sound vessels of the Armed Forces. In addition, the EPA
and DoD reviewed comments on the NPDES VGPs. Documentation of the
consultations is in the administrative docket for the rulemaking.

G. Supporting Documentation

    The rule is supported by the ``Technical Development Document Phase
I Uniform National Discharge Standards for Vessels of the Armed
Forces,'' the UNDS Phase I rules, the ``Final 2013 Vessel General
Permit for Discharges Incidental to the Normal Operation of Vessels,''
the ``2013 Final Issuance of the National Pollutant Discharge
Elimination Vessel General Permit Fact Sheet,'' the ``Final 2014 Small
Vessel General Permit for Discharges Incidental to the Normal Operation
of Vessels Less Than 79 Feet,'' the ``2014 Final Issuance of National
Pollutant Discharge Elimination System Small Vessel General Permit for
Discharges Incidental to the Normal Operation of Vessels Less than 79

Rule,'' the ``Report to Congress: Study of Discharges Incidental to
Normal Operation of Commercial Fishing Vessels and Other Non-
Recreational Vessels Less than 79 Feet,'' the ``Biological Evaluation

Washington, DC 20460; or Online: http://regulations.gov). The NPDES
VGPs background documents also are available online: https://www.epa.gov/npdes/vessels.

II. UNDS Performance Standards Development

    During the development of the discharge performance standards, the
EPA and DoD analyzed the information from the Phase I of UNDS,
considered the relevant language in the NPDES VGPs, and took into the
consideration the seven statutory factors listed in CWA Section
312(n)(2)(B). These seven statutory factors include: The nature of the
discharge; the environmental effects of the discharge; the
practicability of using the MPCD; the effect that installation or use
of the MPCD would have on the operation or operational capability of
the vessel; applicable U.S. law; applicable international standards;
and the economic costs of the installation and use of the MPCD. The EPA
and DoD determined that the NPDES VGPs, which include technology-based
and water quality-based effluent limitations, served as a sound
baseline for developing the discharge performance standards for the 11
discharges in this rule. The subsections below outline the EPA and
DoD's approach to considering the seven statutory factors listed in CWA
Section 312(n)(2)(B).

A. Nature of the Discharge

    During Phase I, the EPA and DoD gathered information on the
discharges incidental to the normal operation of a vessel of the Armed
Forces and developed nature of the discharge reports. The nature of the
discharge reports discuss how the discharge is generated, volumes and
frequencies of the generated discharge, where the discharge occurs, and
the constituents present in the discharge. In addition, the EPA and DoD
reviewed relevant discharge information in the supporting documentation
of the NPDES VGPs. The EPA and DoD briefly describe the nature of each
of the 11 discharges included in this rule; however, the complete
nature of the discharge reports can be found in Appendix A of the
Technical Development Document--EPA 821-R-99-001.

B. Environmental Effects

    Discharges incidental to the normal operation of a vessel of the
Armed Forces have the potential to negatively impact the aquatic
environment. The discharges contain a wide variety of constituents that
have the potential to negatively impact aquatic species and habitats.
These discharges can cause thermal pollution and can contain aquatic
nuisance species, nutrients, bacteria or pathogens (e.g., E. coli and
fecal coliforms), oil and grease, metals, most conventional pollutants
(e.g., organic matter, biochemical oxygen demand, and suspended
solids), and other toxic and non-conventional pollutants with toxic
effects. While it is unlikely that these discharges would cause an
acute or chronic exceedance of the EPA recommended water quality
criteria across a large water body, these discharges have the potential
to cause adverse environmental impacts on a more localized scale due to
the end-of-pipe nature of the discharges. For each of the 11 discharges
included in this rule, the EPA and DoD discuss the constituents of
concern released into the environment and potential water quality
impacts. The discharge performance standards will reduce the discharge
of constituents of concern and mitigate the

environmental risks to the receiving waters.

C. Cost, Practicability, and Operational Impacts

    The universe of vessels of the Armed Forces affected by the rule
encompasses more than 6,000 vessels distributed among the U.S. Navy,
Military Sealift Command, U.S. Coast Guard, U.S. Army, U.S. Marine
Corps, and U.S. Air Force. These vessels range in design and size from
small boats with lengths of less than 20 feet for coastal operations,
to aircraft carriers with lengths of over 1,000 feet for global
operations. Approximately 80 percent of the vessels of the Armed Forces
are less than 79 feet in length. Larger vessels (i.e., vessels with
length greater than or equal to 79 feet) comprise 20 percent of the
vessels of the Armed Forces. The EPA and DoD considered vessel class,
type, and size when developing the discharge standards as not all
vessels of the Armed Forces have the same discharges. For more
information on the various vessel classes, characteristics, and
missions, see the ``Technical Development Document Phase I Uniform
National Discharge Standards for Vessels of the Armed Forces.''
    The EPA and DoD assessed the relative costs, practicability, and
operational impacts of the rule by comparing current operating
conditions and practices of vessels of the Armed Forces with the
anticipated operating conditions and practices that would be required
to meet the discharge performance standards. The EPA and DoD determined
that the discharge performance standards applicable to operating
conditions and practices for the 11 discharges will only result in a
marginal increase in performance costs, practicability, and operational
impacts.

D. Applicable U.S. and International Law

    The EPA and DoD reviewed U.S. laws and international standards that
would be relevant to discharges incidental to the normal operation of a
vessel of the Armed Forces. A number of U.S. environmental laws include
specific provisions for federal facilities and properties that may
result in different environmental requirements for federal and non-
federal entities. Similarly, many international treaties do not apply
to vessels of the Armed Forces either because vessels of the Armed
Forces are entitled to sovereign immunity under international law or
because any particular treaty may apply different approaches to the
adoption of appropriate environmental control measures consistent with
the objects and purposes of such treaties. The EPA and DoD incorporated
any relevant information in the development of the discharge standards
after reviewing the requirements of the following treaties and domestic
implementing legislation, as well as other relevant and potentially
applicable U.S. environmental laws: International Convention for the
Prevention of Pollution from Ships (also referred to as MARPOL);
International Convention on the Control of Harmful Anti-Fouling Systems
on Ships; Act to Prevent Pollution from Ships; CWA Section 311, as
amended by the Oil Pollution Control Act of 1990; CWA Section 402 and
the NPDES VGPs; Federal Insecticide, Fungicide, and Rodenticide Act
(FIFRA); Hazardous Materials Transportation Act; Title X of the Coast
Guard Authorization Act of 2010; National Marine Sanctuaries Act;
Antiquities Act of 1906; Resource Conservation and Recovery Act; Toxic
Substances Control Act; and the St. Lawrence Seaway Regulations.

E. Definitions

    The final rule adds UNDS definitions to 40 CFR part 1700.
Specifically, the final rule defines the following terms: Great Lakes;
minimally-toxic soaps, cleaners, and detergents; phosphate-free soaps,
cleaners, and detergents; and State. These definitions clarify,
simplify, or improve understanding of what the EPA and DoD intended in
establishing the discharge performance standards. Some of the
definitions are slightly different from the definitions established
under the NPDES VGPs to improve clarity and understanding.

III. UNDS Performance Standards

    This section describes the discharge performance standards
determined to be reasonable and practicable to mitigate the adverse
impacts to the marine environment for the 11 discharges. The 11
discharge performance standards described in each section below apply
to vessels of the Armed Forces operating within waters subject to UNDS,
except as otherwise expressly excluded in the ``exceptions'' in 40 CFR
1700.39. In addition, if two or more regulated discharge streams are
combined prior to discharge, then the resulting discharge will need to
meet the discharge performance standards applicable to each of the
discharges that are being combined (40 CFR 1700.40). Furthermore,
recordkeeping (40 CFR 1700.41) and non-compliance reporting (40 CFR
1700.42) apply generally to each discharge performance standard unless
expressly provided in any particular discharge performance standard.

A. Catapult Water Brake Tank and Post-Launch Retraction Exhaust

    The performance standards prohibit the discharge of catapult water
brake tank effluent. In addition, the number of post-launch retractions
must be limited to the minimum required to test and validate the system
and to conduct qualification and operational training.

B. Controllable Pitch Propeller Hydraulic Fluid

    The performance standards require that the protective seals on
controllable pitch propellers (CPPs) be maintained in good operating
order to minimize the leakage of hydraulic fluid. In addition, to the
greatest extent practicable, maintenance activities on CPPs should be
conducted when a vessel is in drydock. If maintenance and repair
activities must occur when the vessel is not in drydock, appropriate
spill response equipment (e.g., oil booms) must be used to contain and
clean any oil leakage. The discharge of CPP hydraulic fluid must not
contain oil in quantities that: Cause a film or sheen upon or
discoloration of the surface of the water or adjoining shorelines; or
cause a sludge or emulsion to be deposited beneath the surface of the
water or upon adjoining shorelines; or contain an oil content above 15
parts per million (ppm) as measured by EPA Method 1664a (as defined in
40 CFR 136.3) or other appropriate method for determination of oil
content as accepted by the International Maritime Organization (IMO)
(e.g., ISO Method 9377) or U.S. Coast Guard; or otherwise are harmful
to the public health or welfare of the United States.

C. Deck Runoff

    The performance standards prohibit flight deck washdowns and
require minimization of other deck washdowns while in port and in
federally-protected waters. Additionally, before non-flight deck
washdowns occur, all exposed decks must be broom cleaned and on-deck
debris, garbage, paint chips, residues, and spills must be removed,
collected, and disposed of onshore in accordance with any applicable
solid waste or hazardous waste management and disposal requirements.
    If a deck washdown or above water line hull cleaning will create a
discharge, the washdown or above water line cleaning must be conducted
with minimally-toxic and phosphate-free soaps, cleaners, and
detergents. The use of soaps that are labeled as toxic is prohibited.
All soaps and cleaners must be used as directed by the label.
Furthermore, soaps, cleaners, and

detergents should not be caustic and must be biodegradable.
    Additionally, where feasible, machinery on deck must have coamings
or drip pans where necessary to collect any oily discharge that may
leak from machinery and prevent spills. The drip pans must be drained
to a waste container for proper disposal onshore in accordance with any
applicable oil and hazardous substance management and disposal
requirements.
    The presence of floating solids, visible foam, halogenated phenol
compounds, and dispersants and surfactants in deck washdowns must be
minimized. Topside surfaces and other above-water-line portions of the
vessel must be well-maintained to minimize the discharge of rust and
other corrosion byproducts, cleaning compounds, paint chips, non-skid
material fragments, and other materials associated with exterior
topside surface preservation. Residual paint droplets entering the
water must be minimized when conducting maintenance painting. The
discharge of unused paint is prohibited. Paint chips and unused paint
residues must be collected and disposed of onshore in accordance with
applicable solid waste and hazardous substance management and disposal
requirements.
    When vessels conduct underway fuel replenishment, scuppers must be
plugged to prevent the discharge of oil. Any oil spilled must be
cleaned, managed, and disposed of onshore in accordance with any
applicable onshore oil and hazardous substance management and disposal
requirements.

D. Firemain Systems

    The firemain system discharges to which UNDS applies include only
the seawater pumped through the firemain system for firemain testing,
maintenance, and training, and to supply water for the operation of
certain vessel systems, rather than to operational firefighting
discharges generally. The performance standards require minimization of
discharges from firemain systems during testing and inspection and to
the greatest extent practicable, firemain system maintenance and
training must be conducted outside of port and as far away from shore
as possible. In addition, firemain system effluent must not be
discharged in federally-protected waters except when needed to comply
with anchor washdown requirements in Subpart 1700.16 (Chain locker
effluent). Firemain system effluent may be employed for secondary uses
and discharged without MPCD controls if the intake comes directly from
the surrounding waters or potable water supplies.

E. Graywater

    The performance standards require that cooking oils (e.g., from
deep fryers), including animal fats and vegetable oils, must not be
intentionally disposed through graywater systems. The performance
standards further require that the addition of incidental quantities of
cooking oils (e.g., associated with washing and rinsing pots and
dishes) to the graywater system must be minimized when the vessel is
within three miles of shore. The performance standards require that
graywater discharges must not contain oil in quantities that cause a
film or sheen upon or discoloration of the surface of the water or
adjoining shorelines; or cause a sludge or emulsion to be deposited
beneath the surface of the water or upon adjoining shorelines; or
contain an oil content above 15 ppm as measured by EPA Method 1664a or
other appropriate method for determination of oil content as accepted
by the IMO (e.g., ISO Method 9377) or U.S. Coast Guard; or otherwise
are harmful to the public health or welfare of the United States. In
addition, minimally-toxic soaps, cleaners and detergents and phosphate-
free soaps, cleaners, and detergents must be used in the galley,
scullery, and laundry. These soaps, cleaners, and detergents should
also be free from bioaccumulative compounds and not lead to extreme
shifts in the receiving water pH (i.e., pH to fall below 6.0 or rise
above 9.0).
    For vessels designed with the capacity to hold graywater, the
performance standards further require that graywater must not be
discharged in federally-protected waters or the Great Lakes. In
addition, such vessels are prohibited from discharging graywater within
one mile of shore if an onshore facility is available and use of such a
facility is reasonable and practicable. When an onshore facility is
either not available or when use of such a facility is not reasonable
and practicable (e.g., when the vessel must operate continuously within
one mile of shore resulting in graywater generation that exceeds the
vessel's holding capacity) production and discharge of graywater must
be minimized within one mile of shore.
    For vessels that do not have the capacity to hold graywater,
graywater production must be minimized in federally-protected waters or
the Great Lakes. In addition, such vessels are prohibited from
discharging graywater within one mile of shore if an onshore facility
is available and use of such a facility is reasonable and practicable.
When an onshore facility is either not available or use of such a
facility is not reasonable and practicable (e.g., when the vessel must
operate continuously within one mile of shore resulting in graywater
generation), production and discharge of graywater must be minimized
within one mile of shore.

F. Hull Coating Leachate

    The performance standards require that antifouling hull coatings
subject to FIFRA (7 U.S.C 136 et seq.) must be applied, maintained, and
removed in a manner consistent with requirements on the coatings' FIFRA
label. The performance standards also prohibit the use of biocides or
toxic materials banned for use in the United States (including those on
EPA's List of Banned or Severely Restricted Pesticides). These
performance standards apply to all vessels of the Armed Forces,
including vessels with a hull coating applied outside of the United
States. Antifouling hull coatings must not contain tributyltin (TBT) or
other organotin compounds as a hull coating biocide. Antifouling hull
coatings may contain small quantities of organotin compounds when the
organotin is used as a chemical catalyst and is not present above 2,500
milligrams of total tin per kilogram of dry paint film. Also, any
organotin antifouling hull coatings used must be designed to not slough
or peel from the vessel hull. In addition, the standards require the
use of non-biocidal alternatives to copper coatings to the greatest
extent practicable. The performance standards also require to the
greatest extent practicable, the use of antifouling hull coatings with
the lowest effective biocide release rates, rapidly biodegradable
components (once separated from the hull surface), or use of non-
biocidal alternatives, such as silicone coatings. Finally, the
performance standards require, to the greatest extent practicable,
avoiding the use of antifouling hull coatings on vessels that are
regularly removed from the water and unlikely to accumulate hull
growth.

G. Motor Gasoline and Compensating Discharge

    The performance standards require that the discharge of motor
gasoline and compensating effluent must not contain oil in quantities
that cause a film or sheen upon or discoloration of the surface of the
water or adjoining shorelines; or cause a sludge or emulsion to be
deposited beneath the surface of the water or upon adjoining
shorelines; or contain an oil content above 15 ppm as measured by EPA

Method 1664a or other appropriate method for determination of oil
content as accepted by the IMO (e.g., ISO Method 9377) or U.S. Coast
Guard; or otherwise are harmful to the public health or welfare of the
United States. In addition, if an oily sheen is observed, the
performance standards require that any spill or overflow of oil must be
cleaned up, recorded, and reported to the National Response Center
immediately. The discharge of motor gasoline and compensating discharge
must be minimized in port and is prohibited in federally-protected
waters.

H. Sonar Dome Discharge

    The performance standards require that the discharge of water from
inside the sonar dome for maintenance activities is prohibited unless
the use of a drydock for the maintenance activity is not feasible
(e.g., when there is no drydock available to support the maintenance
activity, or when the vessel's availability would be impacted to
prevent the vessel from meeting its operational requirements). However,
the water inside the sonar dome may be released for equalization of
pressure between the interior and exterior of the dome. This would
include the discharge of water required to protect the shape,
integrity, and structure of the sonar dome due to internal and external
pressures and forces. Under the performance standards, a biofouling
chemical that is bioaccumulative should not be applied to the exterior
of a sonar dome when a non-bioaccumulative alternative is available.

I. Submarine Bilgewater

    The performance standards require that the discharge of submarine
bilgewater must not contain oil in quantities that cause a film or
sheen upon or discoloration of the surface of the water or adjoining
shorelines; or cause a sludge or emulsion to be deposited beneath the
surface of the water or upon adjoining shorelines; or contain an oil
content above 15 ppm as measured by EPA Method 1664a or other
appropriate method for determination of oil content as accepted by the
IMO (e.g., ISO Method 9377) or U.S. Coast Guard; or otherwise are
harmful to the public health or welfare of the United States. In
addition, the discharge of submarine bilgewater must not contain
dispersants, detergents, emulsifiers, chemicals, or other substances
added for the purpose of removing the appearance of a visible sheen.
The performance standard does not, however, prohibit the use of these
materials in machinery spaces for the purposes of cleaning and
maintenance activities associated with vessel equipment and structures.
The discharge of submarine bilgewater also must only contain substances
that are produced in the normal operation of a vessel. Oil solidifiers,
flocculants, or other additives (excluding any dispersants or
surfactants) may be used to enhance oil-water separation during
processing in an oil-water separator only if such solidifiers,
flocculants, or other additives are minimized in the discharge and do
not alter the chemical composition of the oils in the discharge.
Solidifiers, flocculants, or other additives must not be directly
added, or otherwise combined with, the water in the bilge.
    The performance standards prohibit submarine bilgewater discharges
while the submarine is in port, if the port has the capability to
collect and transfer the bilgewater to an onshore facility. If the
submarine is not in port, then any such discharge must be minimized and
discharged as far from shore as technologically feasible. The
performance standards also require that submarine bilgewater discharges
be minimized in federally-protected waters. Finally, the standards
require that management practices minimize leakage of oil and other
harmful pollutants into the bilge.

J. Surface Vessel Bilgewater/Oil-Water Separator Effluent (OWSE)

    The performance standards prohibit the discharge of bilgewater from
surface vessels equipped with an oil-water separator and require that
any discharge of oil-water separator effluent pass through an oil-
content monitor. All surface vessels greater than 400 gross tons must
be equipped with an oil-water separator. If measurements for gross
tonnage are not available to determine whether the prohibition against
surface vessel bilgewater discharge applies for a particular vessel,
full displacement measurements may be used instead. The performance
standards also require that the discharge of oil-water separator
effluent not occur in port, if the port has the capability to collect
and transfer oil-water separator effluent to an onshore facility. In
addition, the discharge of oil-water separator effluent must be
minimized within one mile of shore, must occur at speeds greater than
six knots if the vessel is underway, and must be minimized in
federally-protected waters.
    For surface vessels not equipped with an oil-water separator, the
performance standards require that bilgewater must not be discharged if
the vessel has the capability to collect, hold, and transfer to an
onshore facility.
    In addition, the discharge of bilgewater/oil-water separator
effluent must not contain dispersants, detergents, emulsifiers,
chemicals, or other substances added for the purpose of removing the
appearance of a visible sheen. The performance standard does not,
however, prohibit the use of these materials in machinery spaces for
the purposes of cleaning and maintenance activities associated with
vessel equipment and structures. The discharge of surface vessel
bilgewater/oil-water separator effluent may only contain substances
that are produced in the normal operation of a vessel. For the
discharge of oil-water separator effluent, oil solidifiers, flocculants
or other additives (excluding any dispersants or surfactants) may be
used to enhance oil/water separation during processing only if such
solidifiers, flocculants, or other additives are minimized and do not
alter the chemical composition of the oils in the discharge.
Solidifiers, flocculants, or other additives must not be directly added
to, or otherwise combined with, the water in the bilge.
    The discharge of surface vessel bilgewater/oil-water separator
effluent must not contain oil in quantities that cause a film or sheen
upon or discoloration of the surface of the water or adjoining
shorelines; or cause a sludge or emulsion to be deposited beneath the
surface of the water or upon adjoining shorelines; or contain an oil
content above 15 ppm as measured by EPA Method 1664a or other
appropriate method for determination of oil content as accepted by the
IMO (e.g., ISO Method 9377) or U.S. Coast Guard; or otherwise are
harmful to the public health or welfare of the United States.
    When a visible sheen is observed as a result of a surface vessel
bilgewater/oil-water separator effluent discharge, the discharge must
be suspended immediately until the problem is corrected. Any spill or
overflow of oil or other engine fluids to waters subject to UNDS must
be cleaned, recorded, and reported immediately to the National Response
Center. The surface vessel must also employ management practices to
minimize leakage of oil and other harmful pollutants into the bilge.
Such practices may include regular inspection and maintenance of
equipment and remediation of oil spills or overflows into the bilge
using oil-absorbent or other spill clean-up materials.

K. Underwater Ship Husbandry

    For vessels greater than 79 feet in length, the performance
standards require that to the greatest extent practicable, vessel hulls
with

antifouling hull coatings must not be cleaned within 90 days after the
antifouling coating application and vessel hulls with a copper-based
antifouling coating must not be cleaned within 365 days after the
antifouling coating application.
    In addition, vessel hulls must be inspected, maintained, and
cleaned to minimize the removal and discharge of antifouling hull
coatings and transport of fouling organisms. To the greatest extent
practicable, rigorous vessel hull cleanings must take place in drydock
or at a land-based facility where the removed fouling organisms or
spent antifouling hull coatings can be disposed of onshore in
accordance with any applicable solid waste or hazardous substance
management and disposal requirements. Vessel hull and niche cleanings
that occur when the vessel is in drydock are not subject to UNDS
because the vessel is not waterborne and, therefore, any materials
removed during a dry dock cleaning would not be subject to UNDS. Vessel
hull and niche cleanings that occur when the vessel is waterborne are
considered to be in-water cleanings. For in-water cleanings, the
performance standards require that cleanings be conducted in a manner
that minimizes the release of antifouling hull coatings and fouling
organisms (e.g., use less abrasive techniques and soft brushes to the
greatest extent practicable) including the use of shore-side or in-
water capture technology as available. Shore-side or in-water cleaning
systems that capture some or all of the removed materials can reduce
the release of fouling organisms and paint particles into the
surrounding environment and allow for collection and onshore disposal
of solids scrubbed from vessel hulls and niches. Regardless, the
discharge of solid, semi-solid, or liquid matter associated with
underwater ship husbandry into waters subject to UNDS from the
operation of a shore-side or in-water cleaning system represents a
discharge incidental to the normal operation of a vessel of the Armed
Forces as defined in 40 CFR 1700.4 because such system is used to
maintain and clean hulls and niches, while the vessel is waterborne.
Vessel hull cleanings must also adhere to any applicable cleaning
requirements found on the coatings' FIFRA label.
    For vessels less than 79 feet in length, the performance standards
require that, to the greatest extent practicable, vessel hulls with
antifouling hull coatings must not be cleaned within 90 days after the
antifouling coating application. In addition, vessel hulls must be
inspected, maintained, and cleaned to minimize the removal and
discharge of antifouling hull coatings and transport of fouling
organisms. As with larger vessels, rigorous vessel hull cleanings must
take place, to the greatest extent practicable, in drydock or at a
land-based facility where the removed fouling organisms or spent
antifouling hull coatings can be disposed of onshore in accordance with
any applicable solid waste or hazardous substance management and
disposal requirements. The performance standards also require that
vessel hull and niche cleanings be conducted in a manner that minimizes
the release of antifouling hull coatings and fouling organisms (e.g.,
use less abrasive techniques and soft brushes to the greatest extent
practicable) including the use of capture technology as available.
Shore-side or in-water cleaning systems that capture some or all of the
removed materials can reduce the release of fouling organisms and paint
particles into the surrounding environment and allow for collection and
onshore disposal of solids scrubbed from vessel hulls and niches.
Regardless, the discharge of solid, semi-solid, or liquid matter
associated with underwater ship husbandry into waters subject to UNDS
from the operation of a shore-side or in-water cleaning system
represents a discharge incidental to the normal operation of a vessel
of the Armed Forces as defined in 40 CFR 1700.4 because such system is
used to maintain and clean hulls and niches, while the vessel is
waterborne. Vessel hull cleanings must also adhere to any applicable
cleaning requirements found on the coatings' FIFRA label and vessels
less than 79 feet in length require inspection of the hull prior to
transport overland to a different body of water to control invasive
species.

IV. Additional Information in the Final Rule

    This section provides an overview of the additional amendments for
40 CFR part 1700. These changes include the reservation of sections for
the remaining discharge standards.
1. Reservation of Sections
    As noted previously, the EPA and DoD are promulgating the final
Phase II standards in three batches. For the purpose of proposing the
remaining batch, the rule reserves the following sections for a
subsequent batch:

Section 1700.17 Clean Ballast
Section 1700.18 Compensated Fuel Ballast
Section 1700.21 Dirty Ballast

V. Changes and Improvements Since the Proposed Rule

A. Public Comment

    On October 7, 2016, the EPA and DoD proposed discharge performance
standards for the 11 discharges, with a 60-day public comment period
that closed on December 6, 2016. The EPA and DoD consider the public
comment period important to creating a rule that is readily
understandable and useful to the public. The EPA and DoD received one
comment on the proposed rule during the comment period, which expressed
support for finalizing the rule. The public comment received can be
viewed under Docket No. EPA-HQ-OW-2013-0351.

B. Modifications to Proposed Standards

    The final rule includes minor modifications to the text of the
proposed definitions and standards to make the final language clearer
and more concise. These changes to the definitions and standards are
intended to be non-substantive and to clarify, simplify, or improve
understanding and readability of the definitions and discharge
performance standards. There are no technical changes to the standards.

VI. Related Acts of Congress and Executive Orders

    Additional information about these statutes and Executive Orders
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review, and Executive
Order 13563: Improving Regulation and Regulatory Review

    This action is not a deemed a significant regulatory action by the
Office of Management and Budget (OMB) and was therefore not submitted
to the OMB for review.

B. Executive Order 13771: Reducing Regulation and Controlling
Regulatory Costs

    This action is not an Executive Order 13771 regulatory action
because this action is not significant under Executive Order 12866.

C. Paperwork Reduction Act

    This action does not impose any new information collection burden
because UNDS Phase II does not create any additional collection of
information beyond that information collection already specified under
the Phase I of UNDS. OMB has previously approved the information
collection requirements contained in the existing regulations (40 CFR
part 1700) under the provisions of

the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned
OMB control number 2040-0187. The OMB control numbers for the EPA's
regulations in 40 CFR are listed in 40 CFR part 9.

D. Regulatory Flexibility Act

    We certify that this action will not have a significant economic
impact on a substantial number of small entities under the Regulatory
Flexibility Act. This action will not impose any requirements on small
entities.

E. Unfunded Mandates Reform Act

    This action does not contain any unfunded mandate as described in
the Unfunded Mandates Reform Act, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments.

F. Executive Order 13132: Federalism

    Executive Order 13132, titled ``Federalism'' (64 FR 43255, August
10, 1999), requires federal agencies to develop an accountable process
to ensure ``meaningful and timely input by state and local officials in
the development of regulatory policies that have federalism
implications.'' ``Policies that have federalism implications'' is
defined in the Executive Order to include regulations that have
``substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.'' Under
Executive Order 13132, federal agencies may not issue a regulation that
has federalism implications and that preempts state law, unless the
agency consults with state and local officials or their representative
national organizations during the development of regulatory policies,
including the proposed regulation.
    The EPA and DoD conclude that the rule, once operationalized in
Phase III, will have federalism implications. When DoD promulgates the
Phase III regulations, adoption and enforcement of new or existing
state or local regulations for the discharge or the design,
construction, installation or use of any MPCD required to control
discharges from a vessel of the Armed Forces will be preempted.
Accordingly, the EPA and DoD provide the following federalism summary
impact statement (FSIS) as required by Section 6(c) of Executive Order
13132.
    During Phase I of UNDS, the EPA and DoD conducted two rounds of
consultation meetings (i.e., outreach briefings) to allow states and
local governments to have meaningful and timely input into the
development of the rulemaking process. Twenty-two states accepted the
offer to be briefed on UNDS and discuss state concerns. The EPA and DoD
provided clarification on the technical aspects of the UNDS process,
including preliminary discharge determinations and analytical
information supporting decisions to control or not control discharges.
State representatives were provided with discharge summaries containing
the description, analysis, and preliminary determination of each of the
39 discharges from vessels of the Armed Forces, 25 of which were
determined to require control.
    During Phase II of UNDS, the EPA and DoD consulted with
intergovernmental associations in the process of developing the
proposed regulation. On March 9, 2016, the EPA held a Federalism
consultation in Washington, DC, and invited representatives from 10 key
national organizations that represent state and local government
associations, as well as groups representing intergovernmental water
professionals, in order to obtain meaningful and timely input in the
development of the proposed discharge standards. The EPA and DoD
informed the state representatives that the two agencies planned to use
the NPDES VGPs effluent limitations as a baseline for developing the
proposed discharge performance standards for the 25 discharges
identified in Phase I as requiring control. During the Federalism
consultation period, the EPA and DoD did not receive any substantive
comments from state and local government entities.
    As required by Section 8(a) of Executive Order 13132, EPA included
a certification from its Federalism Official stating that EPA had met
the Executive Order's requirements in a meaningful and timely manner. A
copy of this certification is included in the official record for this
final action.

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

    This action does not have tribal implications as specified in
Executive Order 13175. This action will not impact vessels operated by
tribes because the final rule only regulates discharges from vessels of
the Armed Forces. However, tribes may be interested in this action
because vessels of the Armed Forces, including U.S. Coast Guard
vessels, may operate on or near tribal waters. The EPA hosted a
National Teleconference on March 23, 2016, in order to obtain
meaningful and timely input during the development of the proposed
discharge standards. The EPA and DoD informed the tribal
representatives that the NPDES VGPs effluent limitations would be used
as a baseline for developing the discharge performance standards for
the 25 discharges identified in Phase I as requiring control. During
the tribal consultation period, the EPA and DoD did not receive any
substantive comments from the Indian Tribal Governments.

H. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks

    This action is not subject to Executive Order 13045 because it is
not economically significant as defined in Executive Order 12866, and
because the EPA and DoD determined that the environmental health or
safety risks addressed by this action do not present a disproportionate
risk to children. The 11 discharge standards are designed to control
discharges incidental to the normal operation of a vessel of the Armed
Forces that could adversely affect human health and the environment.
The standards reduce the adverse impacts to the receiving waters and
any person using the receiving waters, regardless of age.

I. Executive Order 13211: Actions That Concern Regulations That
Significantly Affect Energy Supply, Distribution, and Use

    This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act

    This action involves technical standards in some but not all of the
performance standards. Some of the performance standards use ISO Method
9377--determination of hydrocarbon oil index. ISO Method 9377 is a
voluntary consensus standard developed by an independent, non-
governmental international organization.

K. Coastal Zone Management Act

    The Coastal Zone Management Act (CZMA) requires that each federal
agency activity within or outside the coastal zone that affects any
land or water use or natural resource of the coastal zone shall be
carried out in a manner which is consistent to the maximum extent
practicable with the enforceable policies of approved state management
programs.
    Pursuant to Section 307 of the CZMA, the EPA and DoD have
determined that

the performance standards are consistent to the maximum extent
practicable with the enforceable policies of federally-approved Coastal
Management Plans for the state and territorial coastal zones, that
encompass waters where discharges from vessels of the Armed Forces
would be regulated by UNDS. Following proposal of the UNDS Phase II
Batch Two performance standards on October 7, 2016, the EPA and DoD
provided 35 states and territories with the EPA and DoD's November 2018
``National Consistency Determination: Uniform National Discharge
Standards Program for Phase II Batch Two Discharges.'' In response, 16
states and territories provided concurrence, 17 states and territories
did not respond, so concurrence was conclusively presumed, and both
Connecticut and North Carolina provided conditional concurrence.
Connecticut and North Carolina requested that the UNDS Phase II rules
incorporate certain requirements on discharges into waters under their
respective jurisdictions. The DoD responded in writing to Connecticut
and North Carolina, explaining that applying different requirements in
each coastal water body would conflict with the statutory requirements
set forth in CWA Section 312(n), to include the statutory prohibition
on the adoption or enforcement of any state laws with respect to
regulated discharges.

L. Endangered Species Act

    Section 7(a)(2) of the Endangered Species Act (ESA) requires each
federal agency, in consultation with and with the assistance of the
U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries
Service (NMFS), collectively ``the Services,'' to ensure that the
actions they authorize, fund, or carry out are not likely to adversely
affect the continued existence of any endangered or threatened species
(referred to as ``listed species'') or result in the destruction or
adverse modification of their designated critical habitats.
    The Services published regulations implementing ESA Section 7 at 50
CFR part 402. The regulations provide that a federal agency (such as
the EPA or DoD) must consult with FWS, NMFS, or both if the agency
determines that an activity authorized, funded, or carried out by the
agency may affect listed species or critical habitat. The EPA and DoD
began informal communications with the Services in July 2017. The
informal consultation process included multiple steps: Briefings with
the Services on the content of the rulemaking; discussions of the
proposed outline and methodological approach for development of the
performance standards; information exchanges and requests on current
species lists, rulemaking schedule, and approach to the biological
evaluation; and ultimately the submission of a Biological Evaluation to
the Services on November 16, 2018. The Biological Evaluation described
the anticipated effects of the Uniform National Discharge Standards
Batch Two (this final rule) on aquatic and water-dependent species
listed as threatened or endangered under the ESA and their designated
critical habitat. The Biological Evaluation concluded that the issuance
of the final rule establishing performance standards for the UNDS Batch
Two Rule once implemented, ``may affect'' but is ``not likely to
adversely affect'' species listed or proposed for listing under the
ESA, nor adversely modify designated critical habitat or critical
habitat proposed for designation.
    On March 26, 2019, the FWS concurred in that determination for
species and habitat within that agency's ESA jurisdiction. On December
3, 2018, the NMFS initiated formal consultation due to the scope and
nature of the discharges regulated under UNDS Batch Two Rule. On
November 15, 2019, the NMFS issued a Biological Opinion determining
that the action ``may affect'' and is ``likely to adversely affect,''
but is not likely to jeopardize the continued existence of, species
that are listed or proposed for listing. The Biological Opinion
concluded that hull coating leachate and underwater ship husbandry
discharges may result in non-lethal incidental take of 21 listed
species that occur in ports and harbors with high populations of
vessels of the Armed Forces. The Biological Opinion also concluded that
hull coating leachate and underwater ship husbandry discharges are not
likely to destroy or adversely modify designated critical habitat for
listed species. The incidental take statement in the Biological Opinion
provides non-discretionary reasonable and prudent measures to minimize
the amount and extent of incidental take from these two discharges by
maintaining or reducing the area of impact. It also provides terms and
conditions to implement the reasonable and prudent measures.

M. Executive Order 13112: Invasive Species

    Executive Order 13112, titled ``Invasive Species'' (64 FR 6183,
February 8, 1999), requires each federal agency whose actions may
affect the status of invasive species, to identify such actions, and,
subject to the availability of appropriations, use relevant programs
and authorities to, among other things, prevent, detect, control, and
monitor the introduction of invasive species. As defined by this
Executive Order, ``invasive species'' means an alien species whose
introduction causes, or is likely to cause, economic or environmental
harm or harm to human health.
    As part of the environmental effects analyses developed for each of
the 11 performance standards promulgated in today's rule, the EPA and
DoD considered the control of invasive species when developing the
discharge performance standard (see Section II). Some of the
performance standards provided opportunities for prevention, detection,
control, and monitoring of the introduction of invasive species. For
example, the underwater ship husbandry discharge performance standard
requires the inspection of all vessels under 79 feet in length for the
detection and removal of invasive species prior to transport overland
from one body of water to another. This requirement as well as others
help to prevent or control the introduction of invasive species into
the receiving waters.

N. Executive Order 13089: Coral Reef Protection

    Executive Order 13089, titled ``Coral Reef Protection'' (63 FR
32701, June 16, 1998), requires all federal agencies to identify
actions that may affect U.S. coral reef ecosystems; utilize their
programs and authorities to protect the conditions of such ecosystems;
and, to the extent permitted by law, ensure that any actions they
authorize, fund, or carry out will not degrade the conditions of such
ecosystems. The discharge performance standards in this UNDS Batch II
rulemaking are designed to control or eliminate the discharges
incidental to the normal operation of vessels of the Armed Forces,
ultimately minimizing the potential for causing adverse impacts to the
marine environment including coral reefs.

O. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898, titled ``Federal Actions to Address
Environmental Justice in Minority Populations and Low-Income
Populations'' (59 FR 7629, February 16, 1994) requires all federal
agencies to identify actions that may have a disproportionate negative
impact on the human health or the environment for minority populations,
low-income

populations and/or indigenous peoples. The EPA and DoD determined that
this action does not have disproportionately high and adverse human
health or environmental effects. The discharge performance standards
only apply to vessels of the Armed Forces and reduce adverse impacts to
the aquatic environment.

P. Congressional Review Act

    This action is subject to the Congressional Review Act, and the EPA
will submit a rule report to each House of Congress and to Comptroller
General of the United States. This action is not a ``major rule'' as
defined by 5 U.S.C. 804(2).

detergents should not be caustic and must be biodegradable. All soaps
and cleaners must be used as directed by the label.
    (e) Where feasible, machinery on deck must have coamings or drip
pans, where necessary, to prevent spills and collect any oily discharge
that may leak from machinery. The drip pans must be drained to a waste
container for disposal onshore in accordance with any applicable oil
and hazardous substance management and disposal requirements. The
presence of floating solids, visible foam, halogenated phenol
compounds, dispersants, and surfactants in deck washdowns must be
minimized.
    (f) Topside surfaces and other above water line portions of the
vessel must be well maintained to minimize the discharge of rust (and
other corrosion by-products), cleaning compounds, paint chips, non-skid
material fragments, and other materials associated with exterior
topside surface preservation. Residual paint droplets entering the
water must be minimized when conducting maintenance painting. The
discharge of unused paint is prohibited. Paint chips and unused paint
residues must be collected and disposed of onshore in accordance with
any applicable solid waste and hazardous substance management and
disposal requirements.

    (g) When vessels conduct underway fuel replenishment, scuppers must
be plugged to prevent the discharge of oil. Any oil spilled must be

or the Great Lakes.
    (2) Graywater must not be discharged within one mile of shore if an
onshore facility is available and disposal at such a facility is
reasonable and practicable.
    (3) Production and discharge of graywater must be minimized within
one mile of shore when an onshore facility is either not available or
use of such a facility is not reasonable and practicable.
    (b) For discharges from vessels that do not have the capacity to

graywater system. Small quantities of cooking oils (e.g., from pot and
dish rinsing) must be minimized if added to the graywater system within
three miles of shore.
    (d) Minimally-toxic soaps, cleaners, and detergents and phosphate-
free soaps, cleaners, and detergents must be used in the galley,
scullery, and laundry. These soaps, cleaners, and detergents should
also be free from bioaccumulative compounds and not lead to extreme
shifts in the receiving water pH. For purposes of this subparagraph,
extreme shifts means causing the receiving water pH to fall below 6.0
or rise above 9.0 as a direct result of the discharge.
    (e) The discharge of graywater must not contain oil in quantities
that:
    (1) Cause a film or sheen upon or discoloration of the surface of
