EPA Response to Public Comments Received

June 11, 2019

Approach to EPA Responses

The National Compliance Initiatives selected for fiscal years 2020-2023 advance the Agency's Strategic Plan objectives to improve air quality,
provide for clean and safe water, ensure chemical safety, and improve compliance with our nation's environmental laws while enhancing
shared accountability between the EPA and states and tribes with authorized environmental programs. EPA conducted outreach to states and
tribes and solicited public input through a Federal Register notice. [See 84 Fed. Reg. 2848 (Feb. 8, 2019)]. EPA modified several of the
proposals based on the input we received. Most commenters supported the Agency's proposal to shift from a three-year to a four-year NCI
cycle to better align with the Agency's Strategic Plan and the increased emphasis on collaboration with states and tribes. Several commenters
specifically highlighted and supported the transition from National Enforcement Initiatives to National Compliance Initiatives (NCIs) (as
described in this memorandum from the EPA Assistant Administrator for Enforcement), including the recognition that there are many tools
which can be used to address non-compliance, including training, education and outreach.

Reducing Air Pollution
from the Largest
Sources and Keeping
Raw Sewage and
Contaminated
Stormwater Out of Our
Nation's Waters

Return to core

In the draft proposal, the Office of
Enforcement and Compliance Assurance
(OECA) proposed that two existing NCIs be
returned to the core or standard
enforcement program: Reducing Air Pollution
from the Largest Sources and Keeping Raw
Sewage and Contaminated Stormwater Out
of Our Nation's Waters. Some commenters
supported this transition while others
suggested they should continue as NCIs.

Both programs have been NCIs for several
cycles. EPA, in conjunction with state partners,
has addressed a significant percentage of the
facilities in non-compliance. The EPA and state
regulatory approaches and enforcement efforts
in this sector have resulted in a 90 percent
reduction in sulfur dioxide emissions and an 83
percent reduction in nitrogen oxide emissions
since 1997, while gross electricity generation
has increased by 10 percent. The EPA has
required controls or commenced air compliance
investigations at 91 percent, 96 percent, and 90
percent of facilities in the glass, cement, and

acid manufacturing sectors, respectively.

Under the water initiative, EPA has taken
actions to assure compliance at 97 percent of
large combined sewer systems, 92 percent of
large sanitary sewer systems, and 79 percent of
Phase 1 municipal separate stormwater
systems. Accordingly, the Agency believes that
these two priorities should be returned to the
core enforcement program.

Though these initiatives will be returned to the
core program, EPA will continue its compliance
efforts through concluding on-going compliance
actions; monitoring existing enforcement case
settlements; adapting settlements as necessary
to address changing circumstances or to take
advantage of new technologies; and by initiating
additional inspections, investigations, and
enforcement as warranted.

Reducing Significant
Non-compliance with
National Pollutant
Discharge Elimination
System (NPDES)
Permits

Modify from
prior cycle

Keeping Industrial Pollutants Out of the
Nation's Waters was an FY 2017-2019 NCI. In
the NCI Federal Register notice, the Agency
sought comments on modifying this initiative
to focus on all facilities in significant
noncompliance (SNC) with their Clean Water
Act NPDES permits.

EPA received very few comments with
respect to transitioning the Water NCI from a
focus on Industrial Discharges to NPDES SNC
reduction. One commenter noted that

Compliance with NPDES permits is critical to
protecting our nation's waters. There are
approximately 40,000 major and minor
individually NPDES-permitted facilities in the
country. Over 29 percent of these facilities are
currently in SNC with their permits. Violations
range from failure to submit reports, which can
mask serious deficiencies, to significant
exceedances of effluent limits, which can cause
harm to human health and the environment. In
FY2018, the approximately 11,000 permittees

controlling industrial point source release of
industrial wastewaters is critical to reducing
the treatment burden placed on downstream
drinking water treatment facilities and in
maintain public confidence in the national
environmental regulations. Another
commenter supported the transition and the
focus on overall NPDES non-compliance, not
just sources of industrial pollutants.

that had SNC-level effluent violations
discharged almost four billion pounds of
pollutants above their permitted limits.

The objective of this modified initiative will be
to improve surface water quality and reduce
potential impacts on drinking water by assuring
that all NPDES permittees are complying with
their permits, not just industrial contributors.
The NCI will help improve national data
accuracy and reduce NPDES monitoring,
reporting, and effluent violations.

Ensuring Energy
Extraction Activities
Comply with
Environmental Laws

Replace with new
NCI

EPA received mixed comments on the
proposal to transition Energy Extraction to a
broader NCI not focused on a particular
sector but on significant sources of volatile
organic compounds that have a substantial
impact on air quality. Some commenters
noted that the sector approach has been a
useful strategy in the past and that the oil
and gas sector continues to be a major
source of VOC emissions. One commenter
suggested that Energy Extraction should be
retained but focused on impacts to the
subsurface and groundwater. Others
supported the transition, provided that the
new NCI be defined broadly enough to
encompass both Hazardous Air Pollutants as
well as VOCs which may not be strictly
defined as HAPs.

VOC emissions can have a substantial impact on
air quality and (1) may adversely affect an area's
attainment of National Ambient Air Quality
Standards (NAAQS) or (2) may adversely affect
vulnerable populations. People living in non-
attainment areas or in communities that are
near sources of HAPs may face significant risks
to their health and environment. EPA will merge
our efforts to address both hazardous air
pollutants as well as major sources of VOCs that
have a substantial impact on air quality into one
NCI, Creating Cleaner Air for Communities
(CCAC) - see next initiative for description.

Cutting Hazardous Air
Pollutants (modified to
Creating Cleaner Air
for Communities by
Reducing Excess
Emissions of Harmful
Pollutants from
Stationary Sources for
this cycle)

Continue with
modifications

In the NCI Federal Register notice, OECA
proposed to continue the existing initiative
on Cutting Hazardous Air Pollutants. OECA
also proposed replacing the Ensuring Energy
Extraction Activities Comply with
Environmental Laws initiative with one that
focuses on significant sources of VOCs that
have a substantial impact on air quality and
that may adversely affect vulnerable
populations or an area's attainment status.
The majority of commenters were supportive
of continuing the initiative on HAPs.

As noted above, EPA will merge our efforts to
address both hazardous air pollutants as well as
major sources of VOCs that have a substantial
impact on air quality into one NCI, Creating
Cleaner Air for Communities (CCAC). This NCI
will focus on reducing emissions of both volatile
organic compounds (VOCs) and hazardous air
pollutants (HAPs). For VOC emissions, the NCI
will focus on significant sources of VOCs that
have a substantial impact on air quality and (1)
may adversely affect an area's attainment of
National Ambient Air Quality Standards
(NAAQS) or (2) may adversely affect vulnerable
populations. For HAPs, this NCI will focus on
sources that have a significant impact on air
quality and health in communities, consistent
with the existing NCI on Cutting Hazardous Air
Pollutants.

By merging these approaches, we can
concentrate on air pollution that has a
significant impact on air quality and health in
communities and address emissions
contributing to non-attainment.

requirements. The Association of State and
Territorial Solid Waste Management Officials
(ASTSWMO) suggested that a focus on
proper implementation of waste analysis
plans at Treatment Storage and Disposal
Facilities would be a preferred initiative.

Treatment, Storage, and Disposal Facilities
(TSDFs) and Large Quantity Generators (LQGs).
Releases from hazardous waste facilities can
include releases of constituents known or
suspected to cause cancer or birth defects. In
addition, leaks from these facilities can
contribute to non-attainment with the NAAQS.
After initiating this NCI in the last cycle,
inspections revealed significant noncompliance
and an ongoing need for additional training for
both industry and regulators.

EPA is interested in the suggestion that
compliance with hazardous waste analysis plans
should be an area of focus. EPA will engage
with ASTSWMO on this suggestion.

Reducing Risks of
Accidental Releases at
Industrial and
Chemical Facilities

Continue
initiative

EPA proposed to continue the NCI Reducing
Risks of Accidental Releases at Industrial and
Chemical Facilities. One commenter
supported continuation of the initiative and
another suggested expanding the initiative to
releases to groundwater. The American Fuel
and Petroleum Manufacturers (AFPM)
commented that its industries have the
lowest injury and illness rated among major
industrial sectors. It suggests that EPA
rationale for the continuation of this NCI
does not apply to its members. Further,

AFPM notes that EPA is in the process of

While EPA acknowledges and applauds the low
injury and illness rates cited, this NCI addresses
the risk posed by actual and potential releases
of extremely hazardous substances, regardless
of whether those releases resulted in workplace
injuries. This distinction is important. It is
possible to have a chemical release which
causes minimal injuries, but which nevertheless
has a significant effect on the surrounding
community. We found that many regulated
facilities are neither managing adequately the
risks they pose nor ensuring the safety of their
facilities to protect surrounding communities as
required under CAA Section 112(r). EPA also
acknowledges that the Risk Management

rulemaking resulting in regulatory uncertainly
for AFPM members.

Program regulation is in the process of a new
rulemaking, posing some uncertainly. The NCI
will be updated as necessary to incorporate any
new or modified requirements when the
rulemaking is completed. A broader statutory
obligation under the CAA Section 112(r) General
Duty Clause (GDC) applies to all stationary
sources with regulated substances or other
extremely hazardous substances, regardless of
the quantity of chemical involved. The GDC
requires facilities to identify hazards that may
result from accidental releases by using
appropriate hazard assessment techniques,
designing and maintaining a safe facility, taking
such steps as are necessary to prevent releases,
and minimizing the consequences of those
accidental releases that do occur.

Increasing Compliance
with Drinking Water
Standards at
Community Water
Systems

New initiative

In the NCI Federal Register notice, we sought
input on selecting an NCI to increase
compliance with drinking water standards.
Numerous commenters supported this
concept with varying suggestions on the
scope of the effort.

OECA is selecting Reducing Noncompliance with
Drinking Water Standards at Community Water
Systems as a new NCI for the next cycle. EPA
will take the comments into account as we
move forward to implement this new NCI.

Reducing Children's
Exposure to Lead

New initiative

In the NCI Federal Register notice, we sought
input on selecting an NCI to address
children's exposure to lead. Several
commenters supported that idea.

We agree that reducing lead exposure is a high
priority, but rather than develop a separate,
enforcement program-led NCI, we believe it is
more appropriate to participate in the Agency-
wide lead initiative. The President's Task Force

to Children released its Lead Action Plan in
December 2018. The enforcement and
compliance assurance program will contribute
to the Agency's overall efforts to address lead
exposure as outlined in the Lead Action Plan.
These Agency-wide efforts may include:
(1) increasing compliance with—and awareness
of the importance of—lead-safe renovations
under the Renovation, Repair, and Painting
(RRP) rule; (2) developing a mapping tool to
identify communities with elevated lead
exposures; (3) conducting targeted geographic
initiatives; and (4) undertaking public awareness
campaigns on lead issues.

Stopping Aftermarket
Defeat Devices for
Vehicles and Engines

New initiative
suggested by
commenters

In the NCI Federal Register notice, we invited
the public to propose areas for consideration
as NCIs. Some commenters strongly
recommended an initiative focused on
mobile sources of air pollution. They stressed
that mobile sources are a significant
contributor to air pollution and that the EPA,
through its direct implementation authority,
can play a critical role in addressing these
important pollutant sources.

EPA appreciates the suggestion and will add
Stopping Aftermarket Defeat Devices for
Vehicles and Engines as a new NCI in the next
cycle. This NCI will focus on stopping the
manufacture, sale, and installation of these
defeat devices.
