new water quality-based requirements
for construction sites discharging
stormwater to waters requiring
additional pollutant control. EPA
proposes to issue this construction
general permit for five (5) years, and to
provide permit coverage to eligible
existing and new construction projects
in all areas of the country where EPA is
the National Pollutant Discharge
Elimination System permitting
authority, including Idaho,
Massachusetts, New Hampshire, and
New Mexico, Indian Country Lands,
Puerto Rico, Washington, DC, and U.S.
territories and protectorates.
DATES: Comments on the draft general
permit must be received on or before

‘‘construction activity’’ and ‘‘small
construction activity’’ in existing EPA
regulations at 40 CFR 122.26(b)(14)(x)
and 122.26(b)(15), respectively. If you
have questions regarding the
applicability of this action to a
particular entity, consult one of the
persons listed for technical information
in the preceding FOR FURTHER
INFORMATION CONTACT section.
Eligibility for coverage under the draft
CGP is limited to operators of
stormwater discharges from ‘‘new
sources’’, ‘‘existing permitted
dischargers’’, ‘‘existing unpermitted
dischargers’’, ‘‘new operators of new
sources or existing permitted
dischargers’’, and ‘‘emergency-related
projects’’. A ‘‘new source’’ is a
construction project that commenced or
will commence construction activities
after February 1, 2010, which is the
effective date of the new source
performance standards promulgated as
part of the Construction and
Development (C&D) rule on December 1,
2009. An ‘‘existing permitted
discharger’’ is a construction project that
is not a new source, because
construction activities commenced prior
to February 1, 2010 and prior coverage
was obtained under either the 2003
CGP, the 2008 CGP, or under another
NPDES permit. An ‘‘existing
unpermitted discharger’’ is a
construction project that is not a new
source, because construction activities
commenced prior to February 1, 2010,
but has never received coverage for its
construction discharges under an
effective NPDES permit. A ‘‘new
operator of a new source or existing
permitted discharger’’ is an operator that
replaces an existing operator on a
construction project through transfer or
ownership and/or operation. An
‘‘emergency-related project’’ is one in
which earth-disturbing activities need to
take place immediately in order to
respond to a public emergency (e.g.,
tornado, hurricane, earthquake, flood),
and the related work requires immediate
authorization to avoid imminent
endangerment to human health or the
environment. Coverage under this
permit is available to operators of
eligible projects located in those areas
where EPA is the permitting authority
and has opted to make this general
permit for use. A list of eligible areas is
included in Appendix B of the draft
CGP.

E. What process will EPA follow to
finalize the permit?
II. Background of Permit
After the close of the public comment
period, EPA intends to issue a final
permit on or prior to the expiration date
of the current 2008 CGP. [Please note
that EPA is proposing in another notice
today an extension of the 2008 CGP to
January 31, 2012 in order to provide the
Agency with sufficient time to finalize
this permit.] This permit will not be
issued until all significant comments
have been considered and appropriate
changes made to the permit. EPA’s
responses to public comments received
will be included in the docket as part of
the final permit issuance. Once the final
permit becomes effective, eligible
operators of existing and new
construction projects may seek
authorization under the new CGP. Any
construction site operator obtaining
permit coverage prior to the expiration
date of the 2008 CGP will automatically
remain covered under that permit until
the earliest of:
• The operator submits a Notice of
Termination (NOT); or
• EPA issues an individual permit or
denies coverage under an individual
permit for the site’s stormwater
discharges.
A. Statutory and Regulatory History
The Clean Water Act (‘‘CWA’’)
establishes a comprehensive program
‘‘to restore and maintain the chemical,
physical, and biological integrity of the
Nation’s waters.’’ 33 U.S.C. 1251(a). The
CWA also includes the objective of
attaining ‘‘water quality which provides
for the protection and propagation of
fish, shellfish and wildlife and * * *
recreation in and on the water.’’ 33
U.S.C. 1251(a)(2)). To achieve these
goals, the CWA requires EPA to control
discharges of pollutants from point
sources through the issuance of National
Pollutant Discharge Elimination System
(‘‘NPDES’’) permits.
The Water Quality Act of 1987 (WQA)
added section 402(p) to the Clean Water
Act (CWA), which directed EPA to
develop a phased approach to regulate
stormwater discharges under the NPDES
program. 33 U.S.C. 1342(p). EPA
published a final regulation in the
Federal Register, often called the ‘‘Phase
I Rule’’, on November 16, 1990,
establishing permit application
requirements for, among other things,
‘‘storm water discharges associated with
industrial activity.’’ See 55 FR 47990.
EPA defines the term ‘‘storm water

discharge associated with industrial
activity’’ in a comprehensive manner to
cover a wide variety of facilities. See id.
Construction activities, including
activities that are part of a larger
common plan of development or sale,
that ultimately disturb at least five acres
of land and have point source
discharges to waters of the U.S. were
included in the definition of ‘‘industrial
activity’’ pursuant to 40 CFR
122.26(b)(14)(x). The second rule
implementing section 402(p), often
called the Phase II Rule, was published
in the Federal Register on December 8,
1999. It requires NPDES permits for
discharges from construction sites
disturbing at least one acre but less than
five acres, including sites that are part
of a larger common plan of development
or sale that will ultimately disturb at
least one acre but less than five acres,
pursuant to 40 CFR 122.26(b)(15)(i). See
64 FR 68722. EPA is proposing to issue
this draft CGP under the statutory and
regulatory authority cited above.
NPDES permits issued for
construction stormwater discharges are
required under Section 402(a)(1) of the
CWA to include conditions to meet
technology-based effluent limits
established under Section 301 and,
where applicable, Section 306. Effluent
limitations guidelines (ELGs), and New
Source Performance Standards (NSPS)
are technology-based effluent
limitations that are based on the degree
of control that can be achieved using
various levels of pollutant control
technology as defined in Subchapter III
of the CWA.
Once a new national standard is
established in accordance with these
sections, NPDES permits must
incorporate limits based on such
technology-based standards. See CWA
section 301 and 306, 33 U.S.C. 1311 and
1316, and 40 CFR 122.44(a)(1). Prior to
the issuance of such national standards,
permit authorities are required to
incorporate technology-based limits on
a best professional judgment basis. CWA
section 402(a)(1); 40 CFR
125.3(a)(2)(ii)(B). On December 1, 2009,
EPA published final regulations
establishing technology-based Effluent
Limitations Guidelines (ELGs) and New
Source Performance Standards (NSPS)
for the Construction & Development
(C&D) point source category. See 40 CFR
Part 450, and 74 FR 62996 (December 1,
2009). The Construction & Development
Rule, or ‘‘C&D rule’’, became effective on
February 1, 2010; therefore all NPDES
construction permits issued by EPA or
states after this date must incorporate
the C&D rule requirements. Because
EPA will be issuing its new CGP after
the effective date of the C&D rule, the
E:\FR\FM\25APN1.SGM
25APN1
22886
Federal Register / Vol. 76, No. 79 / Monday, April 25, 2011 / Notices
Agency is required by the CWA and 40
CFR 122.44(a)(1) to incorporate into its
new CGP all applicable C&D rule
requirements.
B. Vacature of the C&D Rule Numeric
Limit and Implications for This Permit
The C&D rule was finalized on
December 1, 2009, and included nonnumeric requirements for erosion and
sediment control, stabilization, and
pollution prevention (see 40 CFR
450.21(a) thru (f)), and, for the first time,
a numeric limitation on the discharge of
turbidity from active construction sites
(see 40 CFR 450.22). Since its
promulgation, EPA discovered that the
data used to calculate the numeric limit
for turbidity were misinterpreted, and
that it was necessary to recalculate the
numeric limit.
On August 12, 2010, EPA filed a
motion with the U.S. Court of Appeals
for the Seventh Circuit, requesting the
Court issue an order vacating and
remanding to the Agency limited
portions of the final C&D rule. To
address the specific issues raised by
petitioners, the motion also provided
that EPA:
jdjones on DSKHWCL6B1PROD with NOTICES
• ‘‘May address (and if necessary take
further regulatory action on) certain impacts
of the final rule specific to linear gas and
electricity utility projects.’’
• Will ‘‘solicit site specific information
regarding the applicability of a numeric
limit’’ to cold weather sites and to small sites
that are part of a larger plan of development
that is subject to the numeric limit.
On August 24, 2010, the U.S. Court of
Appeals for the Seventh Circuit
remanded the matter to EPA but did not
vacate the numeric limit. On September
9, 2010, the National Association of
Home Builders (NAHB) filed a motion
for clarification (which EPA did not
oppose) asking the Court to (1) vacate
the limit and (2) hold the case in
abeyance instead of remanding the
matter to EPA. On September 20, 2010,
the Court granted the motion in part by
ruling to hold the matter in abeyance
pending EPA consideration of the
numeric limit and the other remand
issues, but the Court did not vacate the
numeric limit. Instead, the Court stated
that ‘‘EPA may make any changes to the
limit it deems appropriate, as
authorized by law.’’
EPA issued a direct final rule staying
the current numeric limit and a
companion proposed rule proposing a
stay, and the stay took effect on January
4, 2011, resulting in an indefinite
postponement of the implementation of
the 280 NTU limit. The Agency is
currently preparing to issue a proposed
rule proposing the recalculated limit
and a one-year extension to the first
VerDate Mar<15>2010
15:21 Apr 22, 2011
Jkt 223001
phase-in date for complying with the
numeric limit. EPA will seek public
comment on this recalculated limit and
the one-year extension of the first phasein date, and persons who wish to
comment on the recalculated limit and
extension should submit comments on
that proposal. EPA plans to promulgate
the recalculated numeric limit and the
one-year extension of the first phase-in
date prior to the final issuance of the
new CGP. Therefore, if the numeric
limit and one-year extension are
promulgated and become effective prior
to the issuance of the final CGP, EPA
must by law incorporate the applicable
numeric limit and new first phase-in
date from the ELGs and standards into
the final CGP. With this in mind, EPA
has included a placeholder reference to
the final numeric limit, which will be
replaced by the recalculated numeric
limit in the final permit if it is
promulgated prior to permit issuance.
With respect to the first phase-in date
for complying with the limit (i.e.,
August 1, 2011), EPA notes in the
proposed permit that this date may
change depending on the outcome of the
proposed extension.
III. Summary of the Draft CGP
As stated above, the draft permit
proposed today includes new
requirements that implement the
effluent limitations guidelines and new
source performance standards in the
C&D rule. These proposed new
requirements would require site
operators to install and implement
stormwater measures to accomplish
erosion and sediment control, pollution
prevention, and stabilization, and, for
certain larger construction sites, to meet
a recalculated numeric turbidity limit
and conduct compliance monitoring of
their stormwater discharges. For sites
that discharge to waters where
additional controls are necessary to
ensure compliance with applicable
water quality standards, the draft permit
includes new water quality-based
effluent limits. This section summarizes
the C&D rule requirements upon which
the permit’s proposed technology-based
requirements are based, and highlights
the significant new permit provisions
included in the draft permit.
A. Non-Numeric C&D Rule
Requirements
The non-numeric effluent limitations
in the C&D rule are designed to prevent
the mobilization and discharge of
sediment and sediment-bound
pollutants, such as metals and nutrients,
and to prevent or minimize exposure of
stormwater to construction materials,
debris, and other sources of pollutants
PO 00000
Frm 00025
Fmt 4703
Sfmt 4703
on construction sites. In addition, these
non-numeric effluent limitations limit
the generation of dissolved pollutants.
For background, soil on construction
sites can contain a variety of pollutants
such as nutrients, organics, pesticides,
herbicides, and metals. These pollutants
may be present naturally in the soil,
such as arsenic or selenium, or they may
have been contributed by previous
activities on the site, such as agriculture
or industrial activities. These pollutants,
once mobilized by stormwater, can
detach from the soil particles and
become dissolved pollutants. Once
dissolved, these pollutants would not be
removed by down-slope sediment
controls. Source control through
minimization of soil erosion is therefore
the most effective way of controlling the
discharge of these pollutants.
The non-numeric effluent limits in
the C&D rule, upon which certain
technology-based requirements in the
draft CGP are based, include the
following:
• Erosion and Sediment Controls:
Permittees are required to design,
install, and maintain effective erosion
and sediment controls to minimize the
discharge of pollutants. At a minimum,
such controls must be designed,
installed, and maintained to:
1. Control stormwater volume and
velocity within the site to minimize soil
erosion;
2. Control stormwater discharges,
including both peak flowrates and total
stormwater volume, to minimize erosion
at outlets and to minimize downstream
channel and streambank erosion;
3. Minimize the amount of soil
exposed during construction activity;
4. Minimize the disturbance of steep
slopes;
5. Minimize sediment discharges from
the site. The design, installation and
maintenance of erosion and sediment
controls must address factors such as
the amount, frequency, intensity, and
duration of precipitation, the nature of
resulting stormwater runoff, and soil
characteristics, including the range of
soil particle sizes expected to be present
on the site;
6. To increase sediment removal and
maximize stormwater infiltration,
provide and maintain natural buffers
around surface waters and direct
stormwater to vegetated areas, unless
infeasible; and
7. Minimize soil compaction and,
unless infeasible, preserve topsoil.
• Soil Stabilization Requirements:
Permittees are required to, at a
minimum, initiate soil stabilization
measures immediately whenever any
clearing, grading, excavating, or other
earth disturbing activities have
E:\FR\FM\25APN1.SGM
25APN1
jdjones on DSKHWCL6B1PROD with NOTICES
Federal Register / Vol. 76, No. 79 / Monday, April 25, 2011 / Notices
permanently ceased on any portion of
the site, or temporarily ceased on any
portion of the site and will not resume
for a period exceeding 14 calendar days.
Stabilization must be completed within
a period of time determined by the
permitting authority. In arid, semiarid,
and drought-stricken areas where
initiating vegetative stabilization
measures immediately is infeasible,
vegetative stabilization measures must
be initiated as soon as practicable.
• Dewatering Requirements:
Permittees are required to minimize the
discharge of pollutants from dewatering
trenches and excavations. Discharges
are prohibited unless managed by
appropriate controls.
• Pollution Prevention Measures:
Permittees are required to design,
install, implement, and maintain
effective pollution prevention measures
to minimize the discharge of pollutants.
At a minimum, such measures must be
designed, installed, implemented and
maintained to:
1. Minimize the discharge of
pollutants from equipment and vehicle
washing, wheel wash water, and other
wash waters. Wash waters must be
treated in a sediment basin or an
alternative control that provides
equivalent or better treatment prior to
discharge;
2. Minimize the exposure of building
materials, building products,
construction wastes, trash, landscape
materials, fertilizers, pesticides,
herbicides, detergents, sanitary waste,
and other materials present on the site
to precipitation and to stormwater; and
3. Minimize the discharge of
pollutants from spills and leaks and
implement chemical spill and leak
prevention and response procedures.
• Prohibited Discharges: The
following discharges from regulated
construction sites are prohibited:
1. Wastewater from washout of
concrete, unless managed by an
appropriate control;
2. Wastewater from washout and
cleanout of stucco, paint, form release
oils, curing compounds, and other
construction materials;
3. Fuels, oils, or other pollutants used
in vehicle and equipment operation and
maintenance; and
4. Soaps or solvents used in vehicle
and equipment washing.
• Surface Outlets: When discharging
from basins and impoundments,
permittees are required to utilize outlet
structures that withdraw water from the
surface, unless infeasible.
When EPA was writing the C&D rule’s
final non-numeric effluent limits listed
above, it intended to provide discretion
to permitting authorities to determine
VerDate Mar<15>2010
15:21 Apr 22, 2011
Jkt 223001
how best to implement these provisions
with respect to requiring controls and
measures appropriate for the conditions
in their permitted areas. For example, in
the preamble to the C&D rule, EPA
states ‘‘* * * in the erosion and
sediment control section * * * EPA
simply required that permittees
‘minimize the disturbance of steep
slopes’ leaving it up to the permitting
authority to determine the specific
requirements applicable to owners or
operators of C&D sites to minimize
disturbance of steep slopes in order to
minimize the discharge of pollutants
from the site.’’ See 74 FR 63016. As the
permitting authority responsible for
issuing stormwater permits for
construction activities in four States,
Indian Country lands, Federal facilities,
Washington, DC, and U.S. territories/
protectorates, EPA believes that it is
important in this draft permit to include
requirements that more specifically
define what is necessary to implement
each of the C&D rule’s non-numeric
limits. Accordingly, in translating the
C&D rule requirements into the draft
CGP, EPA added specificity to many of
the C&D rule provisions that it believed
call for further definition, such as the
requirements to ‘‘Provide and maintain
natural buffers’’, ‘‘Minimize steep
slopes’’, and ‘‘Minimize soil
compaction’’, among others. In EPA’s
view, adding specificity to the C&D rulebased requirements in the CGP will
assist permittees in understanding the
Agency’s view of what is required to
comply with the permit.
B. Numeric C&D Rule Requirements
The C&D rule at 40 CFR 450.22
requires compliance for certain sites
with a numeric turbidity limit.
Compliance with the numeric turbidity
limit is to be accomplished in two
phases and applies to construction
activities as follows:
• Any construction activities that will
occur on or after August 1, 2011, which
disturb 20 or more acres of land at one
time, including non-contiguous land
disturbances that take place at the same
time and are part of a larger common
plan of development or sale; and
• Any construction activities that will
occur on or after February 2, 2014, and
disturb 10 or more acres of land at one
time, including non-contiguous land
disturbances that take place at the same
time and are part of a larger common
plan of development or sale.
See 40 CFR 450.22(a). The C&D rule
established an exception from the
numeric limit for sites that receive an
amount of precipitation that in any day
is larger than the local 2-year, 24-hour
storm. See 40 CFR 450.22(b). In addition
PO 00000
Frm 00026
Fmt 4703
Sfmt 4703
22887
to promulgating a numeric limit, the
C&D rule also requires monitoring
consistent with requirements
established by the permitting authority.
See 40 CFR 450.22(a)(2). The rule
specifies that each sample must be
analyzed for turbidity in accordance
with the requirements established by
the permitting authority. See id.
As stated previously, the 280 NTU
numeric limit that was originally
promulgated has been found to be based
on data that was misinterpreted. EPA
has issued a stay of the 280 NTU
numeric limit, which indefinitely
postpones the application of this limit
in permits. EPA also intends to propose
and finalize a recalculated numeric
limit. In accordance with the Agency’s
plan, once a recalculated limit and
extension of the first phase-in date are
promulgated, they would replace the
280 NTU limit and the August 1, 2011
phase-in date, respectively. Assuming
the stay of the 280 NTU limit is in effect,
the CWA does not require states whose
construction stormwater permits expire
prior to the promulgation of the new,
corrected numeric limit to include the
stayed numeric limit of 280 NTU in
their construction stormwater permit.
However, if any state permits expire
after the effective date of a final rule
containing the recalculated numeric
limit, those states would be required
under the CWA to incorporate the new
numeric effluent limit into their
construction stormwater permits.
The draft permit implements the
numeric effluent limit provisions of the
C&D rule by including provisions
explaining which sites are required to
comply with the numeric limit and the
two phase-in dates for compliance
(while noting the possibility that the
first phase-in date may change), the
exceptions where the numeric limit
does not apply, sampling and analysis
requirements for compliance
monitoring, and requirements to report
sampling data to EPA. The draft permit
includes a placeholder reference for the
actual numeric limit itself, which EPA
plans to promulgate prior to the
expiration of the 2008 CGP, so that the
numeric limit may be incorporated into
the new CGP prior to issuance.
C. Water Quality-Based Effluent Limits
Because the C&D rule requirements
are technology-based, they do not
account for the level of pollutant control
that may be necessary in a specific area
to meet applicable water quality
standards. EPA’s regulations at 40 CFR
122.44(d)(1) require permitting
authorities to include additional or
more stringent permit requirements
when necessary to achieve water quality
E:\FR\FM\25APN1.SGM
25APN1
22888
Federal Register / Vol. 76, No. 79 / Monday, April 25, 2011 / Notices
jdjones on DSKHWCL6B1PROD with NOTICES
standards. With this requirement in
mind, the draft CGP includes additional
requirements that apply to those sites
that discharge to waters impaired for
sediment, sediment-related parameters,
or nutrients, including nitrogen and
phosphorus, which are parameters
typically associated with stormwater
discharges from construction sites, and
to those sites that discharge to waters
requiring enhanced protection under a
State or Tribe’s antidegradation
requirements.
D. Summary of Significant Proposed
Changes to the CGP
The draft CGP includes a number of
new or modified requirements, many of
which are related to the implementation
of the new C&D rule effluent limits, and
thus differ from the 2008 CGP. The
following list summarizes the proposed
changes to the CGP:
1. Structure/Appearance of Permit:
EPA attempted to restructure its CGP so
that it would be better organized to
present requirements in a generally
more readable manner. It is EPA’s hope
that this structure will enhance the
permittees’ understanding of and
compliance with the permit’s
requirements. For instance, the permit’s
stormwater control requirements are
organized into distinct and related
categories, such as erosion and sediment
control requirements, stabilization
requirements, and pollution prevention
requirements. Within the erosion and
sediment control requirements of the
permit, EPA has organized the section to
reflect the general sequence of the
construction process. For example, the
proposed permit places in separate
sections requirements that apply to the
site planning phase, which should occur
prior to earth-disturbance, followed by
requirements affecting the selection,
design, and installation of stormwater
controls. Similarly, in the pollution
prevention section, EPA organizes the
requirements based on where in the
construction sequence they would
apply. Therefore, there are requirements
relating to (1) where pollutiongenerating activities may be placed, (2)
how to design stormwater controls, (3)
what performance standards to meet
during construction, and (4) how to
maintain required stormwater controls.
2. Eligibility for Emergency-Related
Construction: EPA proposes to provide
immediate authorization for
construction activities required for
response to public emergencies (e.g.,
tornado, hurricane, flooding).
Immediate authorization would enable
work that is necessary to avoid
imminent endangerment to human
health or the environment to proceed
VerDate Mar<15>2010
15:21 Apr 22, 2011
Jkt 223001
without administrative delay. The
construction operator must still comply
with the terms of the permit, and must
submit an NOI within 7 days of
commencing earth-disturbing activities,
whereas typically operators must submit
NOIs 30 days prior to commencing
earth-disturbing activities. The operator
is then required to develop its
stormwater pollution prevention plan
(SWPPP) within 7 days of submitting
the NOI.
3. Authorization Process/NOIs: EPA
proposes to increase the ‘‘waiting
period’’ from 7 days to 30 days for new
projects. This new timeframe is
intended to better reflect the endangered
species-related reviews that must take
place prior to authorization. EPA also
proposes to maximize the use of its
electronic NOI, or eNOI, process for
authorizing construction discharges by
requiring that construction operators
seek coverage using the eNOI system.
Certain case-by-case exceptions, i.e.,
instances in which a ‘‘paper NOI’’ will
be allowed, will still exist, but approval
by the applicable EPA Region will be
necessary first.
4. Sediment and Erosion Controls:
The draft permit includes specific
requirements that implement the C&D
rule’s sediment and erosion control
limits. While many of these
requirements are already included in
the 2008 CGP, the draft permit includes
more detail in order to properly
implement the C&D rule. The following
is a list of requirements that can be
considered significant modifications to
the 2008 CGP:
i. Buffer Compliance Alternatives—To
implement the C&D rule requirement to
provide and maintain natural buffers
around surface waters, unless feasible,
sites must ensure that any discharges
flowing through the area between the
disturbed portions of the site and any
waters of the U.S. are treated by an area
of undisturbed natural vegetation that
alone or supplemented by erosion and
sediment controls achieves a reduction
in sediment loads equivalent to that
achieved by 50 feet of undisturbed
natural vegetation. Appendix M of the
draft permit has been added to provide
guidance to operators in complying with
this requirement.
ii. Installation of Sediment Controls
Prior to Construction—Operators must
install and make operational all
sediment controls prior to conducting
earth-disturbing activities.
iii. Sediment Removal
Requirements—Operators are
specifically required to remove
deposited sediment on the site, tracked
out of the site, or accumulated near
sediment controls before it compromises
PO 00000
Frm 00027
Fmt 4703
Sfmt 4703
the effectiveness of on-site controls and/
or is discharged to surface waters.
iv. Entrance and Exit Points—Any
entrance and exit points created on the
site must be stabilized for a minimum
of 50 feet into the site.
v. Storm Drain Inlets—Controls must
be installed and maintained to protect
any storm drain inlets to which the site
discharges and that are accessible to the
operator.
vi. Chemical Treatment—Where
operators plan to employ treatment
chemicals to reduce sediment
discharges, they are subject to specific
use restrictions and stormwater control
design requirements.
vii. Dewatering Practices—Specific
controls and discharge restrictions
apply to sites that will discharge
groundwater or accumulated stormwater
removed from excavations, trenches,
foundations, vaults, or other points of
accumulation associated with
construction activity.
5. Stabilization Requirements: The
permit includes modified stabilization
requirements that define more
specifically what EPA requires for
temporary and final stabilization.
Criteria are proposed for both vegetative
and non-vegetative stabilization that are
based on the Revised Universal Soil
Loss Equation’s (RUSLE) cover
management factor, or ‘‘C-factor’’. EPA
has provided guidance in Appendix H
to assist permittees in understanding
what stabilization measures meet the
requirements of the draft permit.
6. Pollution Prevention: Beyond
adopting the specific C&D rule
requirements for pollution prevention
and the prohibition of certain
discharges, the draft permit includes
specific location restrictions (e.g., locate
pollutant-generating activities outside of
any buffers established under the permit
and set back from stormwater
conveyance channels) and design
standards (e.g., install secondary
containment or cover activities). The
pollution prevention requirements also
include a proposal to restrict the
discharge of fertilizers at construction
sites.
7. Numeric Turbidity Limit: EPA
proposes that it will include whatever
numeric turbidity limit is effective
under the C&D rule, at the time of final
permit issuance, as well as applicability
(i.e., phase-in dates), sampling, and
reporting requirements.
8. Water Quality-Based Effluent
Limits: The draft permit includes
specific requirements that apply to sites
discharging to waters impaired for
common pollutants associated with
construction activities, such as sediment
and nutrients. For such sites,
E:\FR\FM\25APN1.SGM
25APN1
Federal Register / Vol. 76, No. 79 / Monday, April 25, 2011 / Notices
construction activities are subject to
additional requirements, including
tighter stabilization deadlines
(immediately initiate stabilization if
construction in an area is inactive for 7
days, as opposed to 14 days) and more
frequent site inspections. For sites
disturbing 10 or more acres at a time,
the permittees would be subject to the
additional requirement to conduct
benchmark monitoring of their
discharge based on benchmarks that are
tied to the receiving water’s water
quality criteria. The permit also
proposes to include additional
requirements for waters identified as
Tier 2, Tier 2.5, or Tier 3 for
antidegradation purposes.
9. Site Inspections: EPA proposes to
make explicit the requirement for
permittees to visually assess the quality
of the discharge (e.g., color, odor,
floating, settled, or suspended solids) if
the site inspection occurs during a
discharge-generating rain event.
10. Corrective Actions: Although the
2008 CGP requires corrective action, it
does not include specific requirements
instructing the permittee as to what
conditions trigger specific corrective
actions and what deadlines apply. The
draft permit includes specific triggering
conditions for corrective action as well
as deadlines to fix such problems and
document what was done.
11. Stormwater Pollution Prevention
Plan (SWPPP): The SWPPP
requirements are modified in
accordance with the proposed changes
discussed above. In general, the
requirements are more specific, but
consistent with the current permit.
12. Notice of Termination: EPA
proposes to include additional
requirements that affect when a site may
terminate coverage under the CGP. For
instance, beyond enabling sites to
terminate coverage when earthdisturbing activities have stopped and
the site is stabilized, the permit would
require the removal of all temporary
stormwater controls and construction
materials, waste, and waste handling
devices.

E. Permit Provisions for Which EPA is
Soliciting Comment
While EPA encourages the public to
review and comment on all provisions
of the draft permit, EPA has included in
the body of the draft CGP several
specific requirements on which it
requests feedback. The following list
summarizes these specific requests for
comment, and where they are included
in the permit:
1. How to submit your NOI—Request
for comment on the transition to a

construction starts—Request for
comment on whether there are
situations in which it would be
infeasible or impracticable to make
operators install all stormwater controls
before commencing earth disturbances.
Part 2.1.3.2.a.
5. Stabilize construction entrance and
exit points—Request for comment on
the feasibility of stabilizing entrance
and exit points for a minimum of 50

practicability of the stabilization
timeframes. Part 2.2.1.2.
8. Stabilization deadlines for arid/
semi-arid areas and sensitive areas—
Request for comment on the proposed
deadlines for initiating and completing
stabilization of exposed areas of the site
in arid and semi-arid areas. EPA also
requests comment on treating as a
sensitive area for stabilization purposes
sites that will conduct construction
activities in critical habitat areas or
areas where listed endangered species
exist. Part 2.2.1.4.
9. Criteria for stabilization/vegetative
stabilization—Request for comment on
whether the C-factor stabilization
criteria should be used as the sole
option for complying with the permit’s
stabilization requirements, as opposed
to allowing, as the draft permit does,
permittees to choose either the C-factor
method or the 70 percent areal cover
approach. Part 2.2.2.1.
10. Pollution prevention standards for
fueling and maintenance of equipment
and vehicles—Request for comment on

whether allowances should be made in
the permit for quarterly reporting for
sites that have not exceeded the
turbidity limit. Part 3.3.9.
17. Discharge limitations for impaired
waters—Request for comment on the
way in which this permit determines
whether there is a discharge to impaired
waters. Part 4.2.
18. Requirements for discharges to
sediment or nutrient-impaired waters
without an EPA-approved or established
TMDL/water quality benchmark
monitoring—Request for comment on
whether benchmark monitoring is an
appropriate tool for assessing the
effectiveness of controls in not
contributing to impairments, and
request for comments on the 10-acre
threshold for requiring sites to conduct
benchmark monitoring. EPA also
requests comment on how benchmark
monitoring might be used for discharges
to waters that are habitat for listed fish
species (e.g., white sturgeon, sockeye
salmon). Part 4.2.2.1.
19. Daily visual examination—
Request for comment on the
appropriateness of daily visual
examinations. Part 4.2.2.3.b.

F. Construction Projects Eligible for
Permit Coverage
This draft permit provides coverage to
eligible operators of ‘‘new sources’’,
‘‘existing permitted dischargers’’,
‘‘existing unpermitted dischargers’’,
‘‘new operators of new sources and
existing permitted dischargers’’, and
‘‘emergency-related projects.’’ Although
the existing 2008 CGP will have
expired, existing permitted dischargers
authorized under that permit will
continue to be authorized to discharge
under that permit, in accordance with
EPA’s regulations at 40 CFR 122.6, for
a period of 90 days after the issuance of
the new permit. Within 90 days of the
issuance of the new CGP, owners/
operators of permitted ongoing projects
must submit a complete Notice of Intent
(NOI) for coverage under the new
permit. New operators of new sources or
existing permitted dischargers that were
authorized under the existing 2008
permit prior to its expiration date must
submit a complete NOI for coverage
under the new permit a minimum of 30
days prior to the date that the transfer
will take place to the new owner/
operator. Operators of emergencyrelated projects are required to submit
their completed NOIs within 7 days of
commencing earth-disturbing activities.

G. Geographic Coverage
This permit provides coverage for
stormwater discharges from
construction activities that occur in
areas not covered by an approved State
NPDES program. The areas of
geographic coverage of this permit are
listed in Appendix B, and include the
States of New Hampshire,
Massachusetts, New Mexico, and Idaho
as well as all Indian Country lands, and
federal facilities in selected states.
Permit coverage is also provided in
Puerto Rico, the District of Columbia,
and the Pacific Island territories. The
only changes to the current permit’s
area of coverage is that Indian Country
lands in Region 4 are now added to the
draft permit’s area of coverage, and due
to a phased delegation of the NPDES
program to the State of Alaska starting
in late 2008, EPA now retains NPDES
permitting authority only for discharges
occurring within the Denali National
Park and Preserve, and in Indian
Country located within the State of
Alaska.
IV. Notice of Intent To Prepare an
Environmental Assessment (EA) for the
National Pollutant Discharge
Elimination System (NPDES) General
Permit for Discharges From Large and
Small Construction Activities
Pursuant to the National
Environmental Policy Act (NEPA) (42
U.S.C. 4321–4307h), the Council on
Environmental Quality’s NEPA
regulations (40 CFR Part 15), and EPA’s
regulations for implementing NEPA (40
CFR Part 6), EPA plans to prepare an
Environmental Assessment (EA) to
analyze the potential environmental
impacts of the new CGP. The EA will
consider the potential environmental
impacts from the discharge of pollutants
in stormwater discharges associated
with construction activity where EPA is
the permitting authority to determine
whether to prepare an Environmental
Impact Statement (EIS).
This notice initiates the scoping
process by inviting comments from
Federal, State, and local agencies,
Indian tribes, and the public to help
identify the environmental issues and
reasonable alternatives to be examined
in the EA. The scoping process will
inform the preparation and issuance of
the draft/preliminary EA, which will be
made available for public comment.
To ensure that EPA has an
opportunity to fully consider your
comments and to facilitate EPA’s
prompt preparation of the EA, scoping
comments should be received on or
before May 25, 2011. You may submit
scoping comments to the Docket ID No.

V. Executive Order 12898: Federal
Actions to Address Environmental
Justice in Minority Populations and
Low-Income Populations
Executive Order (EO) 12898 (59 FR
7629 (Feb. 16, 1994)) establishes federal
executive policy on environmental
justice. Its main provision directs
federal agencies, to the greatest extent
practicable and permitted by law, to
make environmental justice part of their
mission by identifying and addressing,
as appropriate, disproportionately high
and adverse human health or
environmental effects of their programs,
policies, and activities on minority
populations and low-income
populations in the United States.
EPA has determined that this draft
CGP will not have disproportionately
high and adverse human health or
environmental effects on minority or
low-income populations because it
increases the level of environmental
protection for all affected populations
without having any disproportionately
high and adverse human health or
environmental effects on any
population, including any minority or
low-income population. The permit
provisions in this permit include new
requirements for erosion and sediment
control and pollution prevention, and
result in an increase in the level of
environmental protection. The
requirements in this permit apply
equally to all construction projects that
disturb one or more acres in areas where
EPA is the permitting authority, and
therefore do not disproportionately and
adversely affect minority or low-income
populations.

VI. Executive Order 13175:
Consultation and Coordination with
Indian Tribal Governments
In compliance with Executive Order
13175, EPA is in the process of
consulting with tribal officials to gain an
understanding of and, where necessary,
to address the tribal implications of the
draft CGP. In the course of this
consultation, EPA plans to undertake
the following activities:
1. Provide education and outreach on
the draft CGP;
2. Hold national conference call(s) to
discuss issues and concerns of the tribes
and document discussions held in this
call;
3. Solicit comment on the draft
permit; and
4. Provide feedback through a written
communication explaining how tribal
issues and concerns were considered in
the final action. This communication
will be completed and made available to
the tribes at the same time the permit is
promulgated and the other responses to
the comments are published.

Notice.
EPA Regions 1, 2, 3, 5, 6, 7,
8, 9, and 10 propose to modify the 2008
National Pollutant Discharge
Elimination System (NPDES) general
permits for stormwater discharges
associated with construction activity in
order to extend until January 31, 2012
the expiration date of the permit.
Hereinafter, these NPDES general
permits will be referred to as ‘‘permit’’ or
‘‘2008 construction general permit’’ or
‘‘2008 CGP.’’ This proposed modification
would, if finalized, extend the threeyear permit so that it expires on January
31, 2012 instead of June 30, 2011. Prior
to this proposed extension, EPA
modified the 2008 CGP in January 2010
to extend the permit by one year, thus
making it a three-year permit. By
Federal law, no NPDES permit may be
issued for a period that exceeds five
years.
SUMMARY:
EPA is proposing a modification
to its 2008 CGP that would extend the
permit until January 31, 2012. If the
proposed modification is finalized, the
2008 CGP would expire on midnight,
January 31, 2012, instead of June 30,
2011. Comments on EPA’s proposal
must be postmarked by May 25, 2011.

Draft National Pollutant Discharge Elimination System (NPDES)
General Permit for Stormwater Discharges From Construction Activities
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: EPA's Regional Offices are proposing for public comment the
draft National Pollutant Discharge Elimination System general permit
for stormwater discharges from large and small construction activities.
This draft construction general permit includes new requirements that
implement the technology-based Effluent Limitation Guidelines and New
Source Performance Standards, which were issued by EPA for the
construction and development industry on December 1, 2009. The draft
permit also includes new water quality-based requirements for
construction sites discharging stormwater to waters requiring
additional pollutant control. EPA proposes to issue this construction
general permit for five (5) years, and to provide permit coverage to
eligible existing and new construction projects in all areas of the
country where EPA is the National Pollutant Discharge Elimination
System permitting authority, including Idaho, Massachusetts, New
Hampshire, and New Mexico, Indian Country Lands, Puerto Rico,
Washington, DC, and U.S. territories and protectorates.
DATES: Comments on the draft general permit must be received on or

I. General Information
A. Does this action apply to me?
The draft construction general permit (``draft CGP'') applies to
the following construction activities:
Table 1--Entities Potentially Regulated by This Permit
------------------------------------------------------------------------
North American
Industry
Category Examples of Affected Entities Classification
System (NAICS)
Code
------------------------------------------------------------------------
Industry............... Construction site operators disturbing 1 or
more acres of land, or less than 1 acre but
part of a larger common plan of development or
sale if the larger common plan will ultimately
disturb 1 acre or more, and performing the
following activities:
------------------------------------------------
Building, Developing and 233
General Contracting.
Heavy Construction........... 234
------------------------------------------------------------------------
EPA does not intend the preceding table to be exhaustive, but
provides it as a guide for readers regarding entities likely to be
regulated by this action. This table lists the types of activities that
EPA is now aware of that could potentially be affected by this action.
Other types of entities not listed in the table could also be affected.
To determine whether your facility is regulated by this action, you
should carefully examine the definition of
[[Page 22884]]
``construction activity'' and ``small construction activity'' in
existing EPA regulations at 40 CFR 122.26(b)(14)(x) and 122.26(b)(15),
respectively. If you have questions regarding the applicability of this
action to a particular entity, consult one of the persons listed for
technical information in the preceding FOR FURTHER INFORMATION CONTACT
section.
Eligibility for coverage under the draft CGP is limited to
operators of stormwater discharges from ``new sources'', ``existing
permitted dischargers'', ``existing unpermitted dischargers'', ``new
operators of new sources or existing permitted dischargers'', and
``emergency-related projects''. A ``new source'' is a construction
project that commenced or will commence construction activities after
February 1, 2010, which is the effective date of the new source
performance standards promulgated as part of the Construction and
Development (C&D) rule on December 1, 2009. An ``existing permitted
discharger'' is a construction project that is not a new source,
because construction activities commenced prior to February 1, 2010 and
prior coverage was obtained under either the 2003 CGP, the 2008 CGP, or
under another NPDES permit. An ``existing unpermitted discharger'' is a
construction project that is not a new source, because construction
activities commenced prior to February 1, 2010, but has never received
coverage for its construction discharges under an effective NPDES
permit. A ``new operator of a new source or existing permitted
discharger'' is an operator that replaces an existing operator on a
construction project through transfer or ownership and/or operation. An
``emergency-related project'' is one in which earth-disturbing
activities need to take place immediately in order to respond to a
public emergency (e.g., tornado, hurricane, earthquake, flood), and the
related work requires immediate authorization to avoid imminent
endangerment to human health or the environment. Coverage under this
permit is available to operators of eligible projects located in those
areas where EPA is the permitting authority and has opted to make this
general permit for use. A list of eligible areas is included in
Appendix B of the draft CGP.
B. How can I get copies of these documents and other related
information?
1. Docket. EPA has established an official public docket for this
action under Docket ID No. EPA-HQ-OW-2010-0782. The official public
docket is the collection of materials that is available for public
viewing at the Water Docket in the EPA Docket Center, (EPA/DC) EPA
West, Room 3334, 1301 Constitution Ave., NW., Washington, DC 20460.
Although all documents in the docket are listed in an index, some
information is not publicly available, i.e., Confidential Business
Information (CBI) or other information whose disclosure is restricted
by statute. Publicly available docket materials are available in hard
copy at the EPA Docket Center Public Reading Room, open from 8:30 a.m.
to 4:30 p.m., Monday through Friday, excluding legal holidays. The
telephone number for the Public Reading Room is (202) 566-1744 and the
telephone number for the Water Docket is (202) 566-2426.
2. Electronic Access. You may access this Federal Register document
electronically through the United States government on-line source for
Federal regulations at https://www.regulations.gov.
Electronic versions of this draft permit and fact sheet are
available on EPA's NPDES Web site at https://www.epa.gov/npdes/stormwater/cgp.
An electronic version of the public docket is available through the
EPA's electronic public docket and comment system, EPA Dockets. You may

electronically, you may still access any of the publicly available
docket materials through the Docket Facility identified in Section
I.B.1.
C. What should I consider as I prepare my comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or e-mail. Clearly mark all of the information that you
claim to be CBI. For CBI information on computer disks mailed to EPA,
mark the surface of the disk as CBI. Also identify electronically the
specific information contained in the disk or that you claim is CBI. In
addition to one complete version of the specific information claimed as
CBI, you must submit a copy that does not contain the information
claimed as CBI for inclusion in the public document. Information marked
as CBI will not be disclosed except in accordance with procedures set
forth in 40 CFR Part 2.
For public commenters, it is important to note that EPA's policy is
that public comments, whether submitted electronically or in paper,
will be made available for public viewing in EPA's electronic public
docket as EPA receives them and without change, unless the comment
contains copyrighted material, CBI, or other information whose
disclosure is restricted by statute. When EPA identifies a comment
containing copyrighted material, EPA will provide a reference to that
material in the version of the comment that is placed in EPA's
electronic public docket. The entire printed comment, including the
copyrighted material, will be available in the public docket.
Public comments submitted on computer disks that are mailed or
delivered to the docket will be transferred to EPA's electronic public
docket. Public comments that are mailed or delivered to the docket will
be scanned and placed in EPA's electronic public docket. Where
practical, physical objects will be photographed, and the photograph
will be placed in EPA's electronic public docket along with a brief
description written by the docket staff.
2. Tips for Preparing Your Comments. When submitting comments,
remember to:
Identify this permit by docket number and other
identifying information (subject heading, Federal Register date, and
page number).
Where possible, respond to specific questions or organize
comments by referencing a section or part of this permit.
Explain why you agree or disagree, suggest alternatives,
and suggest substitute language for your requested changes.
Describe any assumptions and provide any technical
information and/or data that you used.
If you estimate potential costs or burdens, explain how
you arrived at your estimate in sufficient detail to allow for it to be
reproduced.
Provide specific examples to illustrate your concerns, and
suggest alternatives.
Explain your views as clearly as possible.
To ensure that EPA can read, understand, and therefore
properly respond to comments, the Agency would prefer that commenters
cite, where possible, the paragraph(s) or section in the fact sheet or
permit to which each comment refers.
[[Page 22885]]
Make sure to submit your comments by the comment period
deadline identified.
D. Will public hearings be held on this action?
EPA has not scheduled any public hearings to receive public comment
concerning the draft permit. All persons will continue to have the
right to provide written comments during the public comment period.
However, interested persons may request a public hearing pursuant to 40
CFR 124.12 concerning the draft permit. Requests for a public hearing
must be sent or delivered in writing to the same address as provided
above for public comments prior to the close of the comment period.
Requests for a public hearing must state the nature of the issues
proposed to be raised in the hearing. Pursuant to 40 CFR 124.12, EPA
shall hold a public hearing if it finds, on the basis of requests, a
significant degree of public interest in a public hearing on the draft
permit. If EPA decides to hold a public hearing, a public notice of the
date, time and place of the hearing will be made at least 30 days prior
to the hearing. Any person may provide written or oral statements and
data pertaining to the draft permit at the public hearing.
E. What process will EPA follow to finalize the permit?
After the close of the public comment period, EPA intends to issue
a final permit on or prior to the expiration date of the current 2008
CGP. [Please note that EPA is proposing in another notice today an
extension of the 2008 CGP to January 31, 2012 in order to provide the
Agency with sufficient time to finalize this permit.] This permit will
not be issued until all significant comments have been considered and
appropriate changes made to the permit. EPA's responses to public
comments received will be included in the docket as part of the final
permit issuance. Once the final permit becomes effective, eligible
operators of existing and new construction projects may seek
authorization under the new CGP. Any construction site operator
obtaining permit coverage prior to the expiration date of the 2008 CGP
will automatically remain covered under that permit until the earliest
of:
The operator submits a Notice of Termination (NOT); or
EPA issues an individual permit or denies coverage under
an individual permit for the site's stormwater discharges.

II. Background of Permit
A. Statutory and Regulatory History
The Clean Water Act (``CWA'') establishes a comprehensive program
``to restore and maintain the chemical, physical, and biological
integrity of the Nation's waters.'' 33 U.S.C. 1251(a). The CWA also
includes the objective of attaining ``water quality which provides for
the protection and propagation of fish, shellfish and wildlife and * *
* recreation in and on the water.'' 33 U.S.C. 1251(a)(2)). To achieve
these goals, the CWA requires EPA to control discharges of pollutants
from point sources through the issuance of National Pollutant Discharge
Elimination System (``NPDES'') permits.
The Water Quality Act of 1987 (WQA) added section 402(p) to the
Clean Water Act (CWA), which directed EPA to develop a phased approach
to regulate stormwater discharges under the NPDES program. 33 U.S.C.
1342(p). EPA published a final regulation in the Federal Register,
often called the ``Phase I Rule'', on November 16, 1990, establishing
permit application requirements for, among other things, ``storm water
discharges associated with industrial activity.'' See 55 FR 47990. EPA
defines the term ``storm water discharge associated with industrial
activity'' in a comprehensive manner to cover a wide variety of
facilities. See id. Construction activities, including activities that
are part of a larger common plan of development or sale, that
ultimately disturb at least five acres of land and have point source
discharges to waters of the U.S. were included in the definition of
``industrial activity'' pursuant to 40 CFR 122.26(b)(14)(x). The second
rule implementing section 402(p), often called the Phase II Rule, was
published in the Federal Register on December 8, 1999. It requires
NPDES permits for discharges from construction sites disturbing at
least one acre but less than five acres, including sites that are part
of a larger common plan of development or sale that will ultimately
disturb at least one acre but less than five acres, pursuant to 40 CFR
122.26(b)(15)(i). See 64 FR 68722. EPA is proposing to issue this draft
CGP under the statutory and regulatory authority cited above.
NPDES permits issued for construction stormwater discharges are
required under Section 402(a)(1) of the CWA to include conditions to
meet technology-based effluent limits established under Section 301
and, where applicable, Section 306. Effluent limitations guidelines
(ELGs), and New Source Performance Standards (NSPS) are technology-
based effluent limitations that are based on the degree of control that
can be achieved using various levels of pollutant control technology as
defined in Subchapter III of the CWA.
Once a new national standard is established in accordance with
these sections, NPDES permits must incorporate limits based on such
technology-based standards. See CWA section 301 and 306, 33 U.S.C. 1311
and 1316, and 40 CFR 122.44(a)(1). Prior to the issuance of such
national standards, permit authorities are required to incorporate
technology-based limits on a best professional judgment basis. CWA
section 402(a)(1); 40 CFR 125.3(a)(2)(ii)(B). On December 1, 2009, EPA
published final regulations establishing technology-based Effluent
Limitations Guidelines (ELGs) and New Source Performance Standards
(NSPS) for the Construction & Development (C&D) point source category.
See 40 CFR Part 450, and 74 FR 62996 (December 1, 2009). The
Construction & Development Rule, or ``C&D rule'', became effective on
February 1, 2010; therefore all NPDES construction permits issued by
EPA or states after this date must incorporate the C&D rule
requirements. Because EPA will be issuing its new CGP after the
effective date of the C&D rule, the
[[Page 22886]]
Agency is required by the CWA and 40 CFR 122.44(a)(1) to incorporate
into its new CGP all applicable C&D rule requirements.
B. Vacature of the C&D Rule Numeric Limit and Implications for This
Permit
The C&D rule was finalized on December 1, 2009, and included non-
numeric requirements for erosion and sediment control, stabilization,
and pollution prevention (see 40 CFR 450.21(a) thru (f)), and, for the
first time, a numeric limitation on the discharge of turbidity from
active construction sites (see 40 CFR 450.22). Since its promulgation,
EPA discovered that the data used to calculate the numeric limit for
turbidity were misinterpreted, and that it was necessary to recalculate
the numeric limit.
On August 12, 2010, EPA filed a motion with the U.S. Court of
Appeals for the Seventh Circuit, requesting the Court issue an order
vacating and remanding to the Agency limited portions of the final C&D
rule. To address the specific issues raised by petitioners, the motion
also provided that EPA:
``May address (and if necessary take further regulatory
action on) certain impacts of the final rule specific to linear gas
and electricity utility projects.''
Will ``solicit site specific information regarding the
applicability of a numeric limit'' to cold weather sites and to
small sites that are part of a larger plan of development that is
subject to the numeric limit.
On August 24, 2010, the U.S. Court of Appeals for the Seventh
Circuit remanded the matter to EPA but did not vacate the numeric
limit. On September 9, 2010, the National Association of Home Builders
(NAHB) filed a motion for clarification (which EPA did not oppose)
asking the Court to (1) vacate the limit and (2) hold the case in
abeyance instead of remanding the matter to EPA. On September 20, 2010,
the Court granted the motion in part by ruling to hold the matter in
abeyance pending EPA consideration of the numeric limit and the other
remand issues, but the Court did not vacate the numeric limit. Instead,
the Court stated that ``EPA may make any changes to the limit it deems
appropriate, as authorized by law.''
EPA issued a direct final rule staying the current numeric limit
and a companion proposed rule proposing a stay, and the stay took
effect on January 4, 2011, resulting in an indefinite postponement of
the implementation of the 280 NTU limit. The Agency is currently
preparing to issue a proposed rule proposing the recalculated limit and
a one-year extension to the first phase-in date for complying with the
numeric limit. EPA will seek public comment on this recalculated limit
and the one-year extension of the first phase-in date, and persons who
wish to comment on the recalculated limit and extension should submit
comments on that proposal. EPA plans to promulgate the recalculated
numeric limit and the one-year extension of the first phase-in date
prior to the final issuance of the new CGP. Therefore, if the numeric
limit and one-year extension are promulgated and become effective prior
to the issuance of the final CGP, EPA must by law incorporate the
applicable numeric limit and new first phase-in date from the ELGs and
standards into the final CGP. With this in mind, EPA has included a
placeholder reference to the final numeric limit, which will be
replaced by the recalculated numeric limit in the final permit if it is
promulgated prior to permit issuance. With respect to the first phase-
in date for complying with the limit (i.e., August 1, 2011), EPA notes
in the proposed permit that this date may change depending on the
outcome of the proposed extension.
III. Summary of the Draft CGP
As stated above, the draft permit proposed today includes new
requirements that implement the effluent limitations guidelines and new
source performance standards in the C&D rule. These proposed new
requirements would require site operators to install and implement
stormwater measures to accomplish erosion and sediment control,
pollution prevention, and stabilization, and, for certain larger
construction sites, to meet a recalculated numeric turbidity limit and
conduct compliance monitoring of their stormwater discharges. For sites
that discharge to waters where additional controls are necessary to
ensure compliance with applicable water quality standards, the draft
permit includes new water quality-based effluent limits. This section
summarizes the C&D rule requirements upon which the permit's proposed
technology-based requirements are based, and highlights the significant
new permit provisions included in the draft permit.
A. Non-Numeric C&D Rule Requirements
The non-numeric effluent limitations in the C&D rule are designed
to prevent the mobilization and discharge of sediment and sediment-
bound pollutants, such as metals and nutrients, and to prevent or
minimize exposure of stormwater to construction materials, debris, and
other sources of pollutants on construction sites. In addition, these
non-numeric effluent limitations limit the generation of dissolved
pollutants. For background, soil on construction sites can contain a
variety of pollutants such as nutrients, organics, pesticides,
herbicides, and metals. These pollutants may be present naturally in
the soil, such as arsenic or selenium, or they may have been
contributed by previous activities on the site, such as agriculture or
industrial activities. These pollutants, once mobilized by stormwater,
can detach from the soil particles and become dissolved pollutants.
Once dissolved, these pollutants would not be removed by down-slope
sediment controls. Source control through minimization of soil erosion
is therefore the most effective way of controlling the discharge of
these pollutants.
The non-numeric effluent limits in the C&D rule, upon which certain
technology-based requirements in the draft CGP are based, include the
following:
Erosion and Sediment Controls: Permittees are required to
design, install, and maintain effective erosion and sediment controls
to minimize the discharge of pollutants. At a minimum, such controls
must be designed, installed, and maintained to:
1. Control stormwater volume and velocity within the site to
minimize soil erosion;
2. Control stormwater discharges, including both peak flowrates and
total stormwater volume, to minimize erosion at outlets and to minimize
downstream channel and streambank erosion;
3. Minimize the amount of soil exposed during construction
activity;
4. Minimize the disturbance of steep slopes;
5. Minimize sediment discharges from the site. The design,
installation and maintenance of erosion and sediment controls must
address factors such as the amount, frequency, intensity, and duration
of precipitation, the nature of resulting stormwater runoff, and soil
characteristics, including the range of soil particle sizes expected to
be present on the site;
6. To increase sediment removal and maximize stormwater
infiltration, provide and maintain natural buffers around surface
waters and direct stormwater to vegetated areas, unless infeasible; and
7. Minimize soil compaction and, unless infeasible, preserve
topsoil.
Soil Stabilization Requirements: Permittees are required
to, at a minimum, initiate soil stabilization measures immediately
whenever any clearing, grading, excavating, or other earth disturbing
activities have
[[Page 22887]]
permanently ceased on any portion of the site, or temporarily ceased on
any portion of the site and will not resume for a period exceeding 14
calendar days. Stabilization must be completed within a period of time
determined by the permitting authority. In arid, semiarid, and drought-
stricken areas where initiating vegetative stabilization measures
immediately is infeasible, vegetative stabilization measures must be
initiated as soon as practicable.
Dewatering Requirements: Permittees are required to
minimize the discharge of pollutants from dewatering trenches and
excavations. Discharges are prohibited unless managed by appropriate
controls.
Pollution Prevention Measures: Permittees are required to
design, install, implement, and maintain effective pollution prevention
measures to minimize the discharge of pollutants. At a minimum, such
measures must be designed, installed, implemented and maintained to:
1. Minimize the discharge of pollutants from equipment and vehicle
washing, wheel wash water, and other wash waters. Wash waters must be
treated in a sediment basin or an alternative control that provides
equivalent or better treatment prior to discharge;
2. Minimize the exposure of building materials, building products,
construction wastes, trash, landscape materials, fertilizers,
pesticides, herbicides, detergents, sanitary waste, and other materials
present on the site to precipitation and to stormwater; and
3. Minimize the discharge of pollutants from spills and leaks and
implement chemical spill and leak prevention and response procedures.
Prohibited Discharges: The following discharges from
regulated construction sites are prohibited:
1. Wastewater from washout of concrete, unless managed by an
appropriate control;
2. Wastewater from washout and cleanout of stucco, paint, form
release oils, curing compounds, and other construction materials;
3. Fuels, oils, or other pollutants used in vehicle and equipment
operation and maintenance; and
4. Soaps or solvents used in vehicle and equipment washing.
Surface Outlets: When discharging from basins and
impoundments, permittees are required to utilize outlet structures that
withdraw water from the surface, unless infeasible.
When EPA was writing the C&D rule's final non-numeric effluent
limits listed above, it intended to provide discretion to permitting
authorities to determine how best to implement these provisions with
respect to requiring controls and measures appropriate for the
conditions in their permitted areas. For example, in the preamble to
the C&D rule, EPA states ``* * * in the erosion and sediment control
section * * * EPA simply required that permittees `minimize the
disturbance of steep slopes' leaving it up to the permitting authority
to determine the specific requirements applicable to owners or
operators of C&D sites to minimize disturbance of steep slopes in order
to minimize the discharge of pollutants from the site.'' See 74 FR
63016. As the permitting authority responsible for issuing stormwater
permits for construction activities in four States, Indian Country
lands, Federal facilities, Washington, DC, and U.S. territories/
protectorates, EPA believes that it is important in this draft permit
to include requirements that more specifically define what is necessary
to implement each of the C&D rule's non-numeric limits. Accordingly, in
translating the C&D rule requirements into the draft CGP, EPA added
specificity to many of the C&D rule provisions that it believed call
for further definition, such as the requirements to ``Provide and
maintain natural buffers'', ``Minimize steep slopes'', and ``Minimize
soil compaction'', among others. In EPA's view, adding specificity to
the C&D rule-based requirements in the CGP will assist permittees in
understanding the Agency's view of what is required to comply with the
permit.
B. Numeric C&D Rule Requirements
The C&D rule at 40 CFR 450.22 requires compliance for certain sites
with a numeric turbidity limit. Compliance with the numeric turbidity
limit is to be accomplished in two phases and applies to construction
activities as follows:
Any construction activities that will occur on or after
August 1, 2011, which disturb 20 or more acres of land at one time,
including non-contiguous land disturbances that take place at the same
time and are part of a larger common plan of development or sale; and
Any construction activities that will occur on or after
February 2, 2014, and disturb 10 or more acres of land at one time,
including non-contiguous land disturbances that take place at the same
time and are part of a larger common plan of development or sale.
See 40 CFR 450.22(a). The C&D rule established an exception from the
numeric limit for sites that receive an amount of precipitation that in
any day is larger than the local 2-year, 24-hour storm. See 40 CFR
450.22(b). In addition to promulgating a numeric limit, the C&D rule
also requires monitoring consistent with requirements established by
the permitting authority. See 40 CFR 450.22(a)(2). The rule specifies
that each sample must be analyzed for turbidity in accordance with the
requirements established by the permitting authority. See id.
As stated previously, the 280 NTU numeric limit that was originally
promulgated has been found to be based on data that was misinterpreted.
EPA has issued a stay of the 280 NTU numeric limit, which indefinitely
postpones the application of this limit in permits. EPA also intends to
propose and finalize a recalculated numeric limit. In accordance with
the Agency's plan, once a recalculated limit and extension of the first
phase-in date are promulgated, they would replace the 280 NTU limit and
the August 1, 2011 phase-in date, respectively. Assuming the stay of
the 280 NTU limit is in effect, the CWA does not require states whose
construction stormwater permits expire prior to the promulgation of the
new, corrected numeric limit to include the stayed numeric limit of 280
NTU in their construction stormwater permit. However, if any state
permits expire after the effective date of a final rule containing the
recalculated numeric limit, those states would be required under the
CWA to incorporate the new numeric effluent limit into their
construction stormwater permits.
The draft permit implements the numeric effluent limit provisions
of the C&D rule by including provisions explaining which sites are
required to comply with the numeric limit and the two phase-in dates
for compliance (while noting the possibility that the first phase-in
date may change), the exceptions where the numeric limit does not
apply, sampling and analysis requirements for compliance monitoring,
and requirements to report sampling data to EPA. The draft permit
includes a placeholder reference for the actual numeric limit itself,
which EPA plans to promulgate prior to the expiration of the 2008 CGP,
so that the numeric limit may be incorporated into the new CGP prior to
issuance.
C. Water Quality-Based Effluent Limits
Because the C&D rule requirements are technology-based, they do not
account for the level of pollutant control that may be necessary in a
specific area to meet applicable water quality standards. EPA's
regulations at 40 CFR 122.44(d)(1) require permitting authorities to
include additional or more stringent permit requirements when necessary
to achieve water quality
[[Page 22888]]
standards. With this requirement in mind, the draft CGP includes
additional requirements that apply to those sites that discharge to
waters impaired for sediment, sediment-related parameters, or
nutrients, including nitrogen and phosphorus, which are parameters
typically associated with stormwater discharges from construction
sites, and to those sites that discharge to waters requiring enhanced
protection under a State or Tribe's antidegradation requirements.
D. Summary of Significant Proposed Changes to the CGP
The draft CGP includes a number of new or modified requirements,
many of which are related to the implementation of the new C&D rule
effluent limits, and thus differ from the 2008 CGP. The following list
summarizes the proposed changes to the CGP:
1. Structure/Appearance of Permit: EPA attempted to restructure its
CGP so that it would be better organized to present requirements in a
generally more readable manner. It is EPA's hope that this structure
will enhance the permittees' understanding of and compliance with the
permit's requirements. For instance, the permit's stormwater control
requirements are organized into distinct and related categories, such
as erosion and sediment control requirements, stabilization
requirements, and pollution prevention requirements. Within the erosion
and sediment control requirements of the permit, EPA has organized the
section to reflect the general sequence of the construction process.
For example, the proposed permit places in separate sections
requirements that apply to the site planning phase, which should occur
prior to earth-disturbance, followed by requirements affecting the
selection, design, and installation of stormwater controls. Similarly,
in the pollution prevention section, EPA organizes the requirements
based on where in the construction sequence they would apply.
Therefore, there are requirements relating to (1) where pollution-
generating activities may be placed, (2) how to design stormwater
controls, (3) what performance standards to meet during construction,
and (4) how to maintain required stormwater controls.
2. Eligibility for Emergency-Related Construction: EPA proposes to
provide immediate authorization for construction activities required
for response to public emergencies (e.g., tornado, hurricane,
flooding). Immediate authorization would enable work that is necessary
to avoid imminent endangerment to human health or the environment to
proceed without administrative delay. The construction operator must
still comply with the terms of the permit, and must submit an NOI
within 7 days of commencing earth-disturbing activities, whereas
typically operators must submit NOIs 30 days prior to commencing earth-
disturbing activities. The operator is then required to develop its
stormwater pollution prevention plan (SWPPP) within 7 days of
submitting the NOI.
3. Authorization Process/NOIs: EPA proposes to increase the
``waiting period'' from 7 days to 30 days for new projects. This new
timeframe is intended to better reflect the endangered species-related
reviews that must take place prior to authorization. EPA also proposes
to maximize the use of its electronic NOI, or eNOI, process for
authorizing construction discharges by requiring that construction
operators seek coverage using the eNOI system. Certain case-by-case
exceptions, i.e., instances in which a ``paper NOI'' will be allowed,
will still exist, but approval by the applicable EPA Region will be
necessary first.
4. Sediment and Erosion Controls: The draft permit includes
specific requirements that implement the C&D rule's sediment and
erosion control limits. While many of these requirements are already
included in the 2008 CGP, the draft permit includes more detail in
order to properly implement the C&D rule. The following is a list of
requirements that can be considered significant modifications to the
2008 CGP:
i. Buffer Compliance Alternatives--To implement the C&D rule
requirement to provide and maintain natural buffers around surface
waters, unless feasible, sites must ensure that any discharges flowing
through the area between the disturbed portions of the site and any
waters of the U.S. are treated by an area of undisturbed natural
vegetation that alone or supplemented by erosion and sediment controls
achieves a reduction in sediment loads equivalent to that achieved by
50 feet of undisturbed natural vegetation. Appendix M of the draft
permit has been added to provide guidance to operators in complying
with this requirement.
ii. Installation of Sediment Controls Prior to Construction--
Operators must install and make operational all sediment controls prior
to conducting earth-disturbing activities.
iii. Sediment Removal Requirements--Operators are specifically
required to remove deposited sediment on the site, tracked out of the
site, or accumulated near sediment controls before it compromises the
effectiveness of on-site controls and/or is discharged to surface
waters.
iv. Entrance and Exit Points--Any entrance and exit points created
on the site must be stabilized for a minimum of 50 feet into the site.
v. Storm Drain Inlets--Controls must be installed and maintained to
protect any storm drain inlets to which the site discharges and that
are accessible to the operator.
vi. Chemical Treatment--Where operators plan to employ treatment
chemicals to reduce sediment discharges, they are subject to specific
use restrictions and stormwater control design requirements.
vii. Dewatering Practices--Specific controls and discharge
restrictions apply to sites that will discharge groundwater or
accumulated stormwater removed from excavations, trenches, foundations,
vaults, or other points of accumulation associated with construction
activity.
5. Stabilization Requirements: The permit includes modified
stabilization requirements that define more specifically what EPA
requires for temporary and final stabilization. Criteria are proposed
for both vegetative and non-vegetative stabilization that are based on
the Revised Universal Soil Loss Equation's (RUSLE) cover management
factor, or ``C-factor''. EPA has provided guidance in Appendix H to
assist permittees in understanding what stabilization measures meet the
requirements of the draft permit.
6. Pollution Prevention: Beyond adopting the specific C&D rule
requirements for pollution prevention and the prohibition of certain
discharges, the draft permit includes specific location restrictions
(e.g., locate pollutant-generating activities outside of any buffers
established under the permit and set back from stormwater conveyance
channels) and design standards (e.g., install secondary containment or
cover activities). The pollution prevention requirements also include a
proposal to restrict the discharge of fertilizers at construction
sites.
7. Numeric Turbidity Limit: EPA proposes that it will include
whatever numeric turbidity limit is effective under the C&D rule, at
the time of final permit issuance, as well as applicability (i.e.,
phase-in dates), sampling, and reporting requirements.
8. Water Quality-Based Effluent Limits: The draft permit includes
specific requirements that apply to sites discharging to waters
impaired for common pollutants associated with construction activities,
such as sediment and nutrients. For such sites,
[[Page 22889]]
construction activities are subject to additional requirements,
including tighter stabilization deadlines (immediately initiate
stabilization if construction in an area is inactive for 7 days, as
opposed to 14 days) and more frequent site inspections. For sites
disturbing 10 or more acres at a time, the permittees would be subject
to the additional requirement to conduct benchmark monitoring of their
discharge based on benchmarks that are tied to the receiving water's
water quality criteria. The permit also proposes to include additional
requirements for waters identified as Tier 2, Tier 2.5, or Tier 3 for
antidegradation purposes.
9. Site Inspections: EPA proposes to make explicit the requirement
for permittees to visually assess the quality of the discharge (e.g.,
color, odor, floating, settled, or suspended solids) if the site
inspection occurs during a discharge-generating rain event.
10. Corrective Actions: Although the 2008 CGP requires corrective
action, it does not include specific requirements instructing the
permittee as to what conditions trigger specific corrective actions and
what deadlines apply. The draft permit includes specific triggering
conditions for corrective action as well as deadlines to fix such
problems and document what was done.
11. Stormwater Pollution Prevention Plan (SWPPP): The SWPPP
requirements are modified in accordance with the proposed changes
discussed above. In general, the requirements are more specific, but
consistent with the current permit.
12. Notice of Termination: EPA proposes to include additional
requirements that affect when a site may terminate coverage under the
CGP. For instance, beyond enabling sites to terminate coverage when
earth-disturbing activities have stopped and the site is stabilized,
the permit would require the removal of all temporary stormwater
controls and construction materials, waste, and waste handling devices.
E. Permit Provisions for Which EPA is Soliciting Comment
While EPA encourages the public to review and comment on all
provisions of the draft permit, EPA has included in the body of the
draft CGP several specific requirements on which it requests feedback.
The following list summarizes these specific requests for comment, and
where they are included in the permit:
1. How to submit your NOI--Request for comment on the transition to
a ``paperless'' NOI system for the CGP. Part 1.5.2.
2. Natural buffers and equivalent sediment controls--Request for
comment on the buffer compliance alternatives. Part 2.1.2.1.
3. General design requirements/required design factors--Request for
comment on the concept, not included in the proposal, to adopt a
minimum design storm standard for designing stormwater controls. Part
2.1.3.1.a.
4. Install stormwater controls before construction starts--Request
for comment on whether there are situations in which it would be
infeasible or impracticable to make operators install all stormwater
controls before commencing earth disturbances. Part 2.1.3.2.a.
5. Stabilize construction entrance and exit points--Request for
comment on the feasibility of stabilizing entrance and exit points for
a minimum of 50 feet. Part 2.1.4.1.a.
6. Chemical treatment--Request for comment on the draft permit's
restrictions on the use of polymers, flocculants, or other treatment
chemicals to enhance sediment removal. Part 2.1.4.6.
7. Deadline to complete stabilization activities--Request for
comment on the practicability of the stabilization timeframes. Part
2.2.1.2.
8. Stabilization deadlines for arid/semi-arid areas and sensitive
areas--Request for comment on the proposed deadlines for initiating and
completing stabilization of exposed areas of the site in arid and semi-
arid areas. EPA also requests comment on treating as a sensitive area
for stabilization purposes sites that will conduct construction
activities in critical habitat areas or areas where listed endangered
species exist. Part 2.2.1.4.
9. Criteria for stabilization/vegetative stabilization--Request for
comment on whether the C-factor stabilization criteria should be used
as the sole option for complying with the permit's stabilization
requirements, as opposed to allowing, as the draft permit does,
permittees to choose either the C-factor method or the 70 percent areal
cover approach. Part 2.2.2.1.
10. Pollution prevention standards for fueling and maintenance of
equipment and vehicles--Request for comment on the practicability of
providing secondary containment or cover for fueling and maintenance
areas on the site. Part 2.3.2.1.b.
11. Pollution prevention standards for staging and storage areas--
Request for comment on the practicability of providing secondary
containment or cover for staging and storage areas on the site. Part
2.3.2.3.b.
12. Types of discharge conditions requiring sampling--Request for
comment on whether the permit should include a minimum rainfall amount
below which no sampling is required. Part 3.3.1.1.
13. Sampling frequency--Request for comment on the sampling
frequency specified, and on the alternative option of requiring samples
to be taken once every 2 hours following the first sample. Part 3.3.2.
14. Sampling location--Request for comment on whether the permit
should allow representative samples for other types of construction
projects. Part 3.3.3.4.
15. Actions required if you violate the numeric turbidity limit--
Request for comment on whether the permit should require immediate
notification of EPA for extremely high turbidity levels. Part 3.3.8.
16. Reporting turbidity sample results to EPA--Request for comment
on whether allowances should be made in the permit for quarterly
reporting for sites that have not exceeded the turbidity limit. Part
3.3.9.
17. Discharge limitations for impaired waters--Request for comment
on the way in which this permit determines whether there is a discharge
to impaired waters. Part 4.2.
18. Requirements for discharges to sediment or nutrient-impaired
waters without an EPA-approved or established TMDL/water quality
benchmark monitoring--Request for comment on whether benchmark
monitoring is an appropriate tool for assessing the effectiveness of
controls in not contributing to impairments, and request for comments
on the 10-acre threshold for requiring sites to conduct benchmark
monitoring. EPA also requests comment on how benchmark monitoring might
be used for discharges to waters that are habitat for listed fish
species (e.g., white sturgeon, sockeye salmon). Part 4.2.2.1.
19. Daily visual examination--Request for comment on the
appropriateness of daily visual examinations. Part 4.2.2.3.b.
20. Requirements for discharges to sediment or nutrient-impaired
waters without an EPA-approved or established TMDL--Request for comment
on the proposed additional requirements on sites discharging to
sediment or nutrient-impaired waters. Also request for comment on
whether the focus should be expanded to cover certain biological
impairments attributable to sediment or nutrients. Part 4.2.2.
[[Page 22890]]
21. Requirements for inspections--Request for comment on the
proposed application of the same inspection requirements for linear
projects as to other types of construction projects. Part 5.1.4.
22. Residual chitosan testing--Request for comment on whether there
is a level of chitosan residual below which corrective action would not
be necessary. Part 6.3.1.3.

F. Construction Projects Eligible for Permit Coverage
This draft permit provides coverage to eligible operators of ``new
sources'', ``existing permitted dischargers'', ``existing unpermitted
dischargers'', ``new operators of new sources and existing permitted
dischargers'', and ``emergency-related projects.'' Although the
existing 2008 CGP will have expired, existing permitted dischargers
authorized under that permit will continue to be authorized to
discharge under that permit, in accordance with EPA's regulations at 40
CFR 122.6, for a period of 90 days after the issuance of the new
permit. Within 90 days of the issuance of the new CGP, owners/operators
of permitted ongoing projects must submit a complete Notice of Intent
(NOI) for coverage under the new permit. New operators of new sources
or existing permitted dischargers that were authorized under the
existing 2008 permit prior to its expiration date must submit a
complete NOI for coverage under the new permit a minimum of 30 days
prior to the date that the transfer will take place to the new owner/
operator. Operators of emergency-related projects are required to
submit their completed NOIs within 7 days of commencing earth-
disturbing activities.
G. Geographic Coverage
This permit provides coverage for stormwater discharges from
construction activities that occur in areas not covered by an approved
State NPDES program. The areas of geographic coverage of this permit
are listed in Appendix B, and include the States of New Hampshire,
Massachusetts, New Mexico, and Idaho as well as all Indian Country
lands, and federal facilities in selected states. Permit coverage is
also provided in Puerto Rico, the District of Columbia, and the Pacific
Island territories. The only changes to the current permit's area of
coverage is that Indian Country lands in Region 4 are now added to the
draft permit's area of coverage, and due to a phased delegation of the
NPDES program to the State of Alaska starting in late 2008, EPA now
retains NPDES permitting authority only for discharges occurring within
the Denali National Park and Preserve, and in Indian Country located
within the State of Alaska.
IV. Notice of Intent To Prepare an Environmental Assessment (EA) for
the National Pollutant Discharge Elimination System (NPDES) General
Permit for Discharges From Large and Small Construction Activities
Pursuant to the National Environmental Policy Act (NEPA) (42 U.S.C.
4321-4307h), the Council on Environmental Quality's NEPA regulations
(40 CFR Part 15), and EPA's regulations for implementing NEPA (40 CFR
Part 6), EPA plans to prepare an Environmental Assessment (EA) to
analyze the potential environmental impacts of the new CGP. The EA will
consider the potential environmental impacts from the discharge of
pollutants in stormwater discharges associated with construction
activity where EPA is the permitting authority to determine whether to
prepare an Environmental Impact Statement (EIS).
This notice initiates the scoping process by inviting comments from
Federal, State, and local agencies, Indian tribes, and the public to
help identify the environmental issues and reasonable alternatives to
be examined in the EA. The scoping process will inform the preparation
and issuance of the draft/preliminary EA, which will be made available
for public comment.
To ensure that EPA has an opportunity to fully consider your
comments and to facilitate EPA's prompt preparation of the EA, scoping
comments should be received on or before May 25, 2011. You may submit
scoping comments to the Docket ID No. EPA-HQ-OW-2010-0782 by any of the
following methods:

V. Executive Order 12898: Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes
federal executive policy on environmental justice. Its main provision
directs federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
EPA has determined that this draft CGP will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because it increases the
level of environmental protection for all affected populations without
having any disproportionately high and adverse human health or
environmental effects on any population, including any minority or low-
income population. The permit provisions in this permit include new
requirements for erosion and sediment control and pollution prevention,
and result in an increase in the level of environmental protection. The
requirements in this permit apply equally to all construction projects
that disturb one or more acres in areas where EPA is the permitting
authority, and therefore do not disproportionately and adversely affect
minority or low-income populations.

VI. Executive Order 13175: Consultation and Coordination with Indian
Tribal Governments
In compliance with Executive Order 13175, EPA is in the process of
consulting with tribal officials to gain an understanding of and, where
necessary, to address the tribal implications of the draft CGP. In the
course of this consultation, EPA plans to undertake the following
activities:
1. Provide education and outreach on the draft CGP;
2. Hold national conference call(s) to discuss issues and concerns
of the tribes and document discussions held in this call;
3. Solicit comment on the draft permit; and
4. Provide feedback through a written communication explaining how
tribal issues and concerns were considered in the final action. This
communication will be completed and made available to the tribes at the
same time the permit is promulgated and the other responses to the
comments are published.
