Updates to NPDES eRule Data Elements To Reflect MS4 General
Permit Remand Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to
update specific data elements within the National Pollutant Discharge
Elimination System (NPDES) Electronic Reporting Rule (NPDES eRule)
published on October 22, 2015 (80 FR 64064), that apply to regulated
municipal separate storm sewer systems (MS4s). These changes are
necessary given the promulgation of a separate rulemaking after
publication of the NPDES eRule that modified the NPDES permit
requirements for small MS4s. That rule, referred to as the MS4 General
Permit Remand Rule, published on December 9, 2016 (81 FR 89320), made a
number of the MS4-related data elements in the NPDES eRule no longer
accurate. This proposed rule updates those data elements to be
consistent with the current MS4 regulations, corrects related
typographical errors, and makes other selected clarifications at the
request of state NPDES permitting programs.

DATES: Comments must be received on or before July 29, 2019.

    This table is not intended to be exhaustive, but rather provides a
guide for readers regarding entities likely to be regulated by this
action. This table lists the types of entities that EPA is now aware
could potentially be regulated by this action. Other types of entities
not listed in the table could also be regulated. To determine whether
your entity is regulated by this action, you should carefully examine
the applicability criteria found in 40 CFR 122.26 and 122.32, and the
discussion in the preamble. If you have questions regarding the
applicability of this action

to a particular entity, consult the person listed in the FOR FURTHER
INFORMATION CONTACT section.

B. What action is the agency taking?

    The EPA is proposing a set of changes to the NPDES eRule that
updates the data elements that apply to regulated MS4s. These changes
are necessary because of a separate rulemaking that the EPA promulgated
after publication of the NPDES eRule. That rulemaking, published on
December 9, 2016 and referred to as the MS4 General Permit Remand Rule
(MS4 Remand Rule), modified the NPDES permit requirements for small
MS4s contained within the Phase II stormwater regulations. Promulgation
of these Phase II regulatory changes made a number of the MS4-related
data elements in the NPDES eRule no longer accurate. This proposed rule
updates those specific data elements to make them consistent with
current stormwater Phase II regulations, corrects related typographical
errors, and clarifies some other data elements at the request of state
NPDES permitting authorities. The proposed changes are limited to the
correction of inaccuracies and the addition of requested
clarifications, and do not increase the reporting burden on regulated
MS4 permittees.

C. What is the agency's authority for taking this action?

    This rule proposes to modify the existing NPDES eRule; therefore,
the authorities for this action are derivative of the authorities for
that action. The EPA promulgated the NPDES eRule on October 22, 2015
(80 FR 64064) pursuant to the Clean Water Act (CWA), 33 U.S.C. 1251 et
seq., which added a new part to title 40 (40 CFR part 127) and made
changes to existing regulations. The EPA promulgated the NPDES eRule
under authority of the CWA sections 101(f), 304(i), 308, 402, and 501.
    These proposed updates to the NPDES eRule are necessary because the
EPA promulgated subsequent modifications to the Phase II stormwater
permitting regulations for small MS4s, known as the MS4 Remand Rule.
The authority for that rule is the Federal Water Pollution Control Act,
33 U.S.C. 1251 et seq., including sections 402 and 501. The MS4 Remand
Rule was published on December 9, 2016 (81 FR 89320) and was
incorporated into the Code of Federal Regulations at 40 CFR 122.28(d),
and as modifications to 40 CFR 122.33 thru 122.35.

D. What are the incremental costs and benefits of this action?

    These proposed regulatory updates do not increase the regulatory
burden associated with complying with the NPDES eRule, but rather
correct current inconsistencies between the language used in the
current data elements and the newly modified Phase II stormwater
regulations and make several clarifications suggested by state NPDES
permitting authorities. EPA anticipates no change in the overall cost
burden to affected entities to comply with the NPDES eRule above what
was projected as a result of promulgating the rule.

III. Background

    Under the NPDES eRule (promulgated on October 22, 2015, see 80 FR
64064), NPDES permitting authorities and permittees must replace the
paper-based system of reporting permit information and data with an
electronic system. The rule also lists specific data elements that must
be reported in EPA's national NPDES data system, the Integrated
Compliance Information System (ICIS)-NPDES. See 40 CFR part 127,
Appendix A. Permitting authorities and permittees must begin reporting
electronically for permitted MS4s on December 21, 2020.
    Following the issuance of the NPDES eRule, EPA promulgated changes
to certain Phase II stormwater permitting requirements related to small
MS4s. This rulemaking, referred to as the MS4 General Permit Remand
Rule (MS4 Remand Rule), was published on December 9, 2016 (see 81 FR
89320), and became effective as of January 9, 2017. The Phase II rule
changes address a decision by the U.S. Court of Appeals for the Ninth
Circuit in Environmental Defense Center, et al. v. EPA, 344 F.3d 832
(9th Cir. 2003) (EDC decision). That court found that EPA regulations
for obtaining coverage under a small MS4 general permit did not provide
for adequate public notice, the opportunity to request a hearing, or
permitting authority review to determine whether the best management
practices (BMPs) selected by each MS4 in its stormwater management
program (SWMP) meet the CWA, including the requirement to ``reduce the
discharge of pollutants to the maximum extent practicable.'' The Phase
II rule changes resolved these problems by revising the procedures to
be used to issue and administer small MS4 general permits, and by
making it clear that the terms and conditions of the permit are
enforceable, not the contents of the permittee-developed SWMP.
    Because the description of the MS4-related data elements in
Appendix A of the NPDES eRule were based on the regulations in place
prior to issuance of the MS4 Remand Rule, it is necessary to update the
NPDES eRule to reflect these changes. If left unchanged, the eRule data
elements would be inconsistent with the new requirements for small MS4
permits in the Phase II regulations. EPA is taking this action now to
ensure that such inconsistencies are fixed, and to correct a small
number of typographical errors and other mistakes made in relevant
parts of the Appendix A data elements.
    The EPA is also proposing to clarify the MS4-related data elements
to address suggestions by authorized NPDES programs that participated
in the EPA-State Stormwater Technical Workgroup. The EPA convened the
EPA-State Stormwater Technical Workgroup (Workgroup) to discuss the MS4
data elements listed in Appendix A to 40 CFR part 127. This Workgroup
met bi-weekly from November 2017, to July 2018, and included
approximately 100 subject matter experts from the EPA Headquarters,
seven EPA Regions, and 34 states. The EPA documented member
recommendations in a memorandum entitled Implementation Technical Paper
No. 9: Data Requirements for NPDES Electronic Reporting Rule Stormwater
Information (EPA, October 2018), posted on the EPA's website at https://www.epa.gov/compliance/data-entry-guidance-and-technical-papers. This
technical paper provides more detail on electronic formatting and
submission of data elements required through authorized NPDES program
inspections and oversight, MS4 program compliance monitoring reports,
NPDES permit applications, and NPDES general permit reports [e.g.,
Notices of Intent (NOIs)]. The EPA plans to use this technical paper to
develop electronic reporting tools and to update NPDES data sharing
protocols and schemas, the EPA's NPDES data system (ICIS-NPDES), and
the forthcoming NPDES Noncompliance Report (NNCR).

IV. Types of Changes Proposed To Correct Inconsistencies Between the
NPDES eRule Data Elements and Small MS4 Permit Regulations

    The changes needed to eliminate the current inconsistencies between
the NPDES eRule data elements and the post-MS4 Remand Rule regulations
are limited, and because these inconsistencies are repeated frequently,
they fall into several broad categories. The following describes the
broad categories of inconsistencies and the types of proposed changes.

A. Clarifications Concerning the Proper Role of the NPDES Permit as the
Correct Source of the MS4's Requirements

    The MS4 Remand Rule modified the Phase II stormwater regulations
by, among other things, clarifying that it is the permit that
establishes the enforceable requirements for the MS4. By establishing
procedures for the permitting authority to ensure that the permit
contains all of the requirements to assess compliance, the MS4 Remand
Rule also clarified that these requirements are not found in documents
such as the MS4's Notice of Intent for coverage or its SWMP, unless the
SWMP, or portions of it, has been formally incorporated as part of the
permit following a review, approval, and public notice process. For
instance, the MS4 Remand Rule preamble clarified the relationship
between the permit and the SWMP as follows:

    EPA is revising Sec.  122.34(a) to clarify that the permit, not
the stormwater management program, contains the requirements,
including requirements for each of the six minimum measures, for
reducing pollutants to the maximum extent practicable, protecting
water quality and satisfying the appropriate water quality
requirements of the CWA. . . . [U]nder EPA's small MS4 regulations,
the details included in the permittee's SWMP document are not
directly enforceable as effluent limitations of the permit. The SWMP
document is intended to be a tool that describes the means by which
the MS4 establishes its stormwater controls and engages in the
adaptive management process during the term of the permit. While the
requirement to develop a SWMP document is an enforceable condition
of the permit (see Sec.  122.34(b) of the final rule), the contents
of the SWMP document and the SWMP document itself are not
enforceable as effluent limitations of the permit, unless the
document or the specific details within the SMWP are specifically
incorporated by the permitting authority into the permit. 81 FR
89339 (December 9, 2015).

    The MS4 data elements in Table 2 of the NPDES eRule's Appendix A
data elements were based on the pre-MS4 Remand Rule version of the
Phase II regulations. Therefore, some of the language used for the
current data elements does not accurately reflect that the permit terms
alone constitute the enforceable requirements of the permit. In order
to ensure that reported information related to MS4s accurately reflects
the regulations upon which they are based, the EPA proposes to clarify
the descriptions of the data elements where necessary to ensure that
the requirements that are reported and tracked through electronic
reporting are the terms and conditions of the permit.
    The following is a summary of the changes that the EPA proposes in
order to correct the inconsistencies described above.
     Corrections to data elements that reference the
permittee's intentions as opposed to the permit requirements. Language
in the current Appendix A data elements that describes the permittee's
intentions in implementing the ``minimum control measure'' components
of its stormwater program is not consistent with the current Phase II
regulations. For instance, the current Appendix A data element
description for the public education and outreach minimum control
measure is described as ``The one or more unique codes/descriptions
that identifies educational materials the permittee intends to
distribute or equivalent outreach activities the permittee will
implement to inform the target audience about the impacts of stormwater
discharges and the steps the public can take to reduce stormwater
pollutants'' (emphasis added). Use of this data description made sense
under the pre-MS4 Remand Rule regulations, where the MS4's compliance
obligation was contained within the permittee's SWMP, the contents of
which were also required to be summarized in the MS4's NOI, if the
permitting authority elected to issue a general permit for eligible
small MS4s.
    The MS4 Remand Rule clarified, among other things, that the MS4's
description of its compliance actions does not substitute for the terms
and conditions in the permit. The revised Phase II regulations make it
clear that the permittee's compliance is judged by whether it has met
the requirements of the permit; the permittee's intention as reflected
in its SWMP does not constitute the basis for permit compliance.
Though, in the example above, this language accurately reflected
existing regulatory requirements for the public education and outreach
minimum control measure prior to the MS4 Remand Rule, its emphasis on
the intention of the permittee, rather than the permit requirements, is
inconsistent with the revised Phase II regulations.
    EPA's proposed rule modifies the relevant language for each of the
data elements that includes this type of language to reflect that the
permit establishes the enforceable requirements, not the SWMP or NOI.
Using the public education and outreach example again, this proposed
rule revises the data element description to read as follows: ``The one
or more unique codes/descriptions that identifies the permit elements
associated with the public education and outreach program requirements,
including any educational materials the permittee is required to
distribute or equivalent outreach activities the permittee must
implement to inform the target audience about the impacts of stormwater
discharges and the steps the public can take to reduce stormwater
pollutants.'' This modification clarifies that it is the specific
``permit elements'' related to the public education and outreach
program that the regulations require the MS4 to report to the EPA.
Another related, yet minor, change would modify the corresponding
``Data Name'' to reflect that it is not the details within the SWMP
that define the permittee's compliance responsibilities. Therefore,
instead of using ``MS4 Public Education Program'' as the data name, the
name would refer to ``Public Education and Outreach Permit
Requirements.'' These same changes would be made to the data elements
for the other minimum control measures.
     Corrections to data elements that refer to the MS4's
``measurable goals'' as opposed to its permit requirements. Several of
the data elements refer to the permittee's ``measurable goals,'' which
is language that is no longer current after EPA modified the Phase II
regulations. Previously, small MS4s were required to submit information
describing the ``specific actions taken by the permittee to implement
each BMP and the frequency and the dates for such actions.'' See 64 FR
68763 (December 8, 1999). The submitted measurable goals were then used
as the basis for the permittee's enforceable requirements, and the
permittee was required to evaluate and submit annual reports on the
progress made with respect to meeting these measurable goals.
References to the MS4's measurable goals were largely removed from the
Phase II regulations to more clearly convey that the terms and
conditions in the relevant permit are enforceable, not the permittee's
proposed measurable goals.
    EPA's proposed rule removes in the current data elements references
to measurable goals and replaces them with language that refers to the
``specific schedules or deadlines'' for complying with the relevant
requirements of the permit. For instance, one of the current Appendix A
data elements associated with the construction site stormwater minimum
control measure is described as ``The one or more unique codes/
descriptions that identify the measurable goals associated with the
construction program, including, as appropriate, the months and years
in which the permittee will undertake required actions, including
interim milestones and the frequency of the action.'' The proposed rule
revises this language as follows: ``The one or more

unique codes/descriptions that identify specific schedules or deadlines
for complying with the permit's construction requirements, including,
as appropriate, the months and years in which the permittee must
undertake each required action, including interim milestones and the
frequency of the action.'' Another related, yet minor, change modifies
the corresponding ``Data Name'' to remove language that references the
measurable goal and substitutes it with the permit's relevant
``deadlines.''
     Updates to the data element(s) associated with permit
requirements established in addition to the minimum control measure
requirements. The proposed rule also updates the language used to
describe MS4 terms and conditions that are included in the permit to
address the modified Phase II regulatory language at 40 CFR 122.34(c)
related to ``other applicable NPDES requirements.'' These changes
include updates to the language used for the ``Data Name'' and ``Data
Description.'' The proposed rule also corrects an error by adding a
data element that was omitted from the current Table 2 related to the
deadlines associated with ``other applicable permit requirements.''
     Additional clarifications to accurately characterize the
source of data on permit requirements. The proposed rule suggests a few
additional changes to clarify that the source of data on an MS4's
permit requirements is the permit itself, not the permit application or
NOI. For instance, the current title for one of the Table 2 sections
for MS4 data elements is ``Municipal Separate Storm Sewer System (MS4)
Information on NPDES Permit Application or Notice of Intent.'' In order
to clarify that the terms and conditions that the MS4 is responsible
for meeting are found in the permit, EPA proposes to modify this title
as follows: ``Municipal Separate Storm Sewer System (MS4) Information
in NPDES Permit.''

B. Other Conforming Changes To Ensure Consistency With the Current
Phase II Regulations

     Removing data element made unnecessary or obsolete by the
modified Phase II regulations. One of the current data elements
requires information from permittees that is no longer required under
the revised Phase II regulations. The data element titled MS4 Permit
Components Descriptions and Measurable Goals would be deleted from
Table 2 of Appendix A in the section entitled ``Compliance Monitoring
Activity Information (Data Elements Specific to Municipal Storm Sewer
System Program Reports).'' The current data element requests
information on ``all of the permitted components and measurable goals
that are included in the MS4 permit.'' This data element is redundant
of the data element that would now be titled ``Municipal Separate Storm
Sewer System (MS4) Information in NPDES Permit,'' and for that reason
may be removed.
     Changes to conform data elements to current Phase II
reporting requirements. The following are changes made to data elements
to reflect the current Phase II reporting requirements for small MS4s
under 40 CFR 122.34(d)(3). These data elements are all located in the
section entitled ``Compliance Monitoring Activity Information (Data
Elements Specific to Municipal Storm Sewer System Program Reports).''
    1. Status of Compliance with Each Minimum Control Measure. The
proposed rule modifies this data element to reflect the changes made to
the description of information required to be reported under 40 CFR
122.34(d)(3)(i). To reflect the fact that the Phase II regulations were
changed to require the permittee to include in its report ``[t]he
status of compliance with permit terms and conditions,'' conforming
changes are made to the Data Name so that the revised Data Name is
``Status of Compliance with MS4 Permit Requirements.'' Similar changes
are made to the Data Description to read as follows: ``The unique code
. . . that identifies if the permittee has complied with the MS4 permit
requirements.''
    2. Results of Information Collected and Analyzed. The current data
elements inadvertently omit information required to be reported under
40 CFR 122.34(d)(3)(ii). This provision requires small MS4 permittees
to include in their annual reports ``[r]esults of information collected
and analyzed, including monitoring data, if any, during the reporting
period.'' The proposed rule corrects this omission by adding a new data
element to capture this information.
    3. Progress and Summary of Results with Each Minimum Control
Measure. The proposed rule modifies this data element to reflect the
changes made to the description of information required to be reported
under 40 CFR 122.34(d)(3)(iii). To reflect the modified description of
the information to be reported, namely ``[a] summary of the storm water
activities the permittee proposes to undertake to comply with the
permit during the next reporting cycle,'' conforming changes are made
to the Data Name (i.e., it would be changed to ``Summary of Activities
Undertaken to Comply with the MS4 Permit Requirements'') and to the
Data Description (i.e., it would be changed to ``This is a text summary
describing the stormwater activities undertaken by each permittee to
comply with the MS4 permit requirements.'').
    4. Changes to MS4 Permittee's Components and Measurable Goals. The
proposed rule modifies this data element to reflect the changes made to
the description of information required to be reported at 40 CFR
122.34(d)(3)(iv). To reflect the changes in the regulations that
require the permittee to include in its report ``[a]ny changes made
during the reporting period to the permittee's storm water management
program,'' conforming changes will be made to the Data Name (i.e., it
would be changed to ``Summary of Activities Undertaken to Comply with
the MS4 Permit Requirements'') and to the Data Description (i.e., it
would be changed to ``The one or more codes/descriptions that describe
. . . any changes made to the MS4 permittee's Stormwater Management
Program (SWMP) during the reporting period.'').
     Clarification related to data provided for small MS4
permittees under a Two-Step General Permit approach. For permitting
authorities that use a ``Two-Step General Permit'' under 40 CFR
122.28(d)(2) to provide permit coverage for small MS4s, there is
flexibility regarding whether the permittee or the NPDES authority will
be responsible for submitting data initially. EPA envisions that most
NPDES authorities will choose to require the permittee to supply the
initial information that characterizes what actions the MS4 proposes to
take to address the permit requirements as a first step. Then, during
the second step of the permitting process, the permitting authority
will modify this information as necessary to reflect the final permit
requirements. To allow or authorize this approach, the proposed rule
includes the following text for many of the data elements in the ``MS4
NPDES Permit-Related Information'' section: ``This data element
includes proposed activities that are submitted by small MS4s seeking
coverage under a `Two-Step General Permit.' Following completion of the
second permitting step, the authorized NPDES program will be
responsible for sharing the final permit terms and conditions with the
U.S. EPA national NPDES data system as required in Subpart B, 40 CFR
127.''
    Additionally, the EPA proposes adding a note to the MS4 Permit-
Related Information section of Table 2 that

provides a basic explanation of how the Two-Step General Permit process
is designed to work, and how the permit information for these types of
permits is to be reported. The following text is proposed for the note:
``Small MS4s seeking coverage under a `Two-Step General Permit' issued
pursuant to Sec.  122.28(d)(2) will be required to submit to the
authorized NPDES program information on stormwater control activities
they propose to take to address specific requirements. The authorized
NPDES program will review this information and then establish, through
a second permitting step, additional permit terms and conditions, as
necessary to satisfy the MS4 permit standard, for each MS4. The
authorized NPDES programs should use their best professional judgement
to adequately identify the mandatory set of requirements using actual
language from the permit, summarized versions of one or more permit
requirements, or a mix of actual and summarized permit requirements.
Any summary of permit requirements should provide a clear understanding
of the one or more permit requirements. The requirements listed in this
section will be used to facilitate electronic reporting of the MS4
Program Report.''
     Updates to regulatory citations to reflect current Phase
II regulations. The proposed rule would update a number of the existing
MS4 regulatory citations in Table 2 of Appendix A in order to reflect
changes made to the Phase II regulations, and, in a few instances, to
correct erroneous citations that are currently included in the table.
For instance, the current table references 40 CFR 122.28(b)(2)(ii) for
the supporting authority for the data elements associated with each of
the minimum control measures. Because the modified Phase II regulations
now include a section addressing small MS4 general permits, this
citation would be updated to refer to the correct section (i.e., 40 CFR
122.28(d)). Elsewhere, the proposed rule adds references to 40 CFR
122.33(b) to more accurately reflect the current Phase II regulatory
authority for requiring basic system information. The proposed rule
also provides the updated reference to the correct annual reporting
provision (i.e., 40 CFR 122.34(d)(3)). Other examples include the
proposed addition of updated citations for Phase I MS4s, such as an
updated citation to 40 CFR 122.26(d)(2)(iv)(A)(6), (B)(5), and (D)(4)
to support the use of the data element for ``Deadlines Associated with
Public Education and Outreach Permit Requirements'' for Phase I MS4s.
     Corrections to current description of the frequency of
required small MS4 reporting. The current Table 1 imprecisely notes
that small MS4s are required to report only in years two and four of
permit coverage. While this is correct for small MS4s that have already
been permitted for at least one permit term, if the permittee is in its
first permit term, it is required to report annually for the entire
permit term. The proposed rule corrects this inaccuracy. See 40 CFR
122.34(d)(3).
     Clarification of the types of MS4 permit holders that can
be chosen under the data element for MS4 Permit Class. The proposed
rule includes a minor update to the examples of MS4 permit types under
the MS4 Permit Class data element, which better reflect the types of
general permits that are described under the revised Phase II
permitting regulations. The following examples would replace the
current examples: Large/Medium MS4 permit (Phase I), Small MS4 permit
(Phase II)--Comprehensive General Permit, Small MS4 permit (Phase II)--
Two-Step General Permit, Small MS4 permit (Phase II)--Individual
Permit.

C. Other Clarifications Requested by NPDES Permitting Authorities

    During meetings of the EPA-State Stormwater technical workgroup
(see Section III), Regional and state subject matter experts suggested
the need for additional clarification to the MS4 data elements. The
clarifications that are included in the proposed rule are described as
follows.
     Revised description of the types of entities potentially
covered under an MS4 permit. The data description that accompanies the
unique MS4 identifier data element does not reflect the fact that
regulated small MS4s can also include so-called ``non-traditional
MS4s,'' such as colleges or universities, military installations,
transportation systems, and state and federal facilities. In order to
more accurately describe the different types of MS4s that can be
regulated, the proposed rule includes the following modified language:
``The unique identifier for each entity covered under an MS4 permit
(e.g., city, county, incorporated town, unincorporated town, college or
university, local school board, military installation, highways or
other thoroughfares, federal facility, state facility, prison).''
    A further clarification would be added to better describe how the
unique identifier can be used to apply to multiple MS4 entities covered
under one permit, as follows: ``Use of this identifier allows for
better tracking of how the MS4 permit elements apply to each entity
covered under the MS4 permit (e.g., if one MS4 NPDES permit covers two
cities, the authorized NPDES program may elect to assign each city with
a unique identifier). The authorized NPDES program will make the final
determination on how to identify entities covered under an MS4
permit.'' Lastly, a minor change would be made to the Data Name to
better describe the types of entities that may be regulated; the Data
Name would now read as ``Unique MS4 Regulated Entity Identifier''
instead of ``Unique Identifier for Each Municipality Covered Under MS4
Permit.''
    Additionally, to better match the existing regulations, the
proposed rule replaces references throughout Table 2 to
``municipality'' with the word or phrase ``entity'' or ``MS4-regulated
entity.''
     Inclusion of a unique identifier for each permit
requirement or set of permit requirements. The proposed rule would
require that each unique permit requirement or set of permit
requirements be designated with a ``Unique MS4 Activity Identifier.''
This addition is intended to improve the accuracy of compliance
reporting by linking permit requirements to a unique identifier. EPA
does not consider this additional identifier to constitute a change in
reporting burden given that information on permit requirements is
already required; this new element will merely ensure that each
individual permit requirement (referred to in Appendix A as ``the one
or more unique codes/descriptions that identify'' the permit
requirement) can be recognized with its own unique number or other
identifier.
     Consolidation of data elements related to tracking
implementation activities performed by other government entities. The
existing data elements require information to be submitted with the
annual report on whether the MS4 permittee is relying on other
government entities to satisfy any permit obligations, and to provide
the status of their implementation activities. To assist the states in
more accurately tracking these other government entities to the
specific permit requirements for which they have assumed
responsibility, the proposed rule moves the requirement to report on
the MS4's reliance on other government entities to a different section
of Table 2, namely the MS4 NPDES Permit-Related Information section.
The Technical Workgroup indicated that this change would enable NPDES
permitting authorities to obtain information on the MS4's reliance on
other government entities in a way that will better enable them to
ensure that reporting on the compliance status of these specific

permit responsibilities will be accurate and more easily understood. By
making this change, EPA proposes deleting two existing elements, which
would already be addressed, namely the ``MS4 Reliance on Other
Government Entities Status'' and ``MS4 Reliance on Other Government
Entities Permit Component Status'' data elements.
     Clarification of permit information required for storm
sewer system map. The proposed rule would clarify that, for previously
permitted MS4 permittees, rather than requiring information on ``the
status of the permittee's storm sewer system map'' associated with the
Illicit Discharge Detection and Elimination permit requirement, a more
direct way of conveying this information is to request the ``date of
the most recent storm sewer system map.'' Additionally, the proposed
rule would clarify that the requirement to show all ``MS4 outfalls'' on
the storm sewer system map excludes private outfalls. This
clarification is consistent with the regulatory definition of MS4,
which is limited to stormwater conveyances ``owned or operated by a . .
. public body'' at 40 CFR 122.26(b)(8)(i). Privately-owned conveyances
and their associated outfalls do not fall within the definition of an
MS4 because they are not ``owned or operated by a . . . public body.''
     Relocation of MS4 industrial stormwater control data
element. The proposed rule would move the Phase I MS4 industrial
stormwater control data element from its current location in the
``Compliance Monitoring Activity'' section of Table 2 to the newly
named MS4 NPDES Permit-Related Information section. This change is not
substantive, but merely intended to better reflect the fact that this
information is typically provided prior to permit coverage, much like
the other information included in that same section.
    Additionally, the proposed rule would add an accompanying data
element for any permit deadlines associated with the industrial
stormwater control requirements. EPA does not consider this a new
reporting burden, but rather a clarification that where the permit
establishes specific deadlines for actions related to industrial
stormwater control, compliance with these dates must be tracked.
     Ability to submit further information regarding instances
of noncompliance. The existing data element requiring information on
whether the permittee has complied with the MS4 permit requirements
limits the information submitted to a ``Yes'' or ``No'' response.
Members of the Technical Workgroup recommended that MS4s be given the
opportunity to provide further information for context if the answer is
``No'' (e.g., that the MS4 was not in compliance with one or more
permit requirements). To address this recommendation, the proposed rule
suggests clarifying that MS4s as necessary will be asked to provide
information related to noncompliance.
     Clarification of information required to be reported in
the summary of activities to comply with the MS4 permit requirements.
The proposed rule clarifies that among the information that must be
conveyed by the MS4 in its annual report is a summary of activities
undertaken (1) as part of the industrial stormwater control program
(for Phase I MS4s and select Phase II MS4s that have industrial
stormwater requirements), and (2) to comply with permit requirements
during the next reporting period. This clarification does not
constitute a new reporting burden since this information was already
required to be reported; the proposed text just makes the requirement
more clear.
     Clarification regarding how information on enforcement
actions taken by Phase II MS4s is to be reported. The proposed rule
would clarify that Phase II MS4s are not required to distinguish
between different types of enforcement action, as Phase I MS4s are
required to do. In contrast with Phase I MS4s, Phase II MS4s may simply
report any enforcement action taken as a ``Phase II MS4 Enforcement
Action.'' The permitting authority may elect to provide this option as
a system default so that MS4 permittees may simply select ``Phase II
MS4 Enforcement Action'' to fulfill this requirement for the reporting
period.
     Clarification related to data elements that may not apply
to non-traditional MS4s. The proposed rule would provide further
clarification on the data elements that may not apply because non-
traditional MS4s typically do not possess the requisite legal authority
to enforce stormwater laws. The following sentence would be added to
three data elements (i.e., ``MS4 Enforcement Action Type,'' ``MS4
Enforcement Action Total by Type,'' and ``MS4 Enforcement Agency''):
``This data element may have different reported data for non-
traditional MS4s (e.g., transportation MS4s) as they may not have legal
authority to enforce one or more MS4 permit requirements and may report
on items like referrals to the state permitting authorities or use
mechanisms such as encroachment permits.''
     Clarification regarding how to report the specific MS4
enforcement agency in the annual report. The proposed rule suggests
alternate wording to better explain how MS4 permittees will
specifically identify in the annual report the specific MS4 enforcement
agency that was responsible for taking enforcement action during the
reporting period. The proposed language explains that the permittee
will select the MS4 enforcement agency from among the unique MS4
regulated entities identified during the permit application process for
co-permittees applying for coverage under an individual permit, unless
there is only one regulated entity.

V. Statutory and Executive Orders Reviews

    Additional information about these statutes and Executive Orders
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.

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

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

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

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

C. Paperwork Reduction Act

    This action does not impose any new information collection burden
under the PRA. OMB has previously approved the information collection
activities contained in the existing regulations and has assigned OMB
control number 2020-0035. The proposed rule would impose no new
information collection burdens beyond what has already been approved by
OMB for the NPDES eRule published on October 22, 2015 (80 FR 64064).
This proposed rule is limited to updating the language used to describe
various data requirements for MS4 permittees to reflect recent changes
to the underlying NPDES regulations and to correct various errors and
omissions.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. In
making this determination, the impact of concern is any significant
adverse economic

impact on small entities. An agency may certify that a rule will not
have a significant economic impact on a substantial number of small
entities if the rule relieves regulatory burden, has no net burden, or
otherwise has a positive economic effect on the small entities subject
to the rule. This proposed rule would impose no new regulatory burdens
on regulated entities in the NPDES program. The action is limited to
updating the language used to describe various data requirements for
MS4 permittees to reflect recent changes to the underlying NPDES
regulations, to correct various errors and omissions, to make targeted
clarifications by request of state NPDES permitting authorities. We
have therefore concluded that this action will have no net regulatory
burden for all directly regulated small entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or
more as described in UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments. The action imposes
no enforceable duty on any state, local or tribal governments or the
private sector.

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.

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

    This proposed rule does not have tribal implications, as specified
in Executive Order 13175. EPA considered the potential impacts on
tribes and concluded that there would be no substantial direct
compliance costs or impact on tribes. Because the purpose of the
proposed rule is to eliminate inconsistencies between regulations and
application forms, improve permit documentation, transparency and
oversight, provide clarifications to existing regulations, and delete
outdated provisions, it is not expected to have substantial direct
effects on tribal governments, on the relationship between the federal
government and Indian tribes, or on the distribution of power and
responsibilities between the federal government and Indian tribes, as
specified in Executive Order 13175. Executive Order 13175 does not
apply to this action and EPA determined that tribal consultation is not
necessary for this action. The EPA specifically solicits input on this
proposed action from tribal officials.
    The EPA notes that it consulted with tribal officials under the EPA
Policy on Consultation and Coordination with Indian Tribes early in the
process of developing the final NPDES eRule, which this proposal would
modify, to permit them to have meaningful and timely input into its
development. A summary of that consultation is provided in Section
VIII.F of the final NPDES eRule preamble at 80 FR 64094.

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

    EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that EPA has reason to believe may disproportionately affect children,
per the definition of ``covered regulatory action'' in section 2-202 of
the Executive Order. This action is not subject to Executive Order
13045 because it does not concern an environmental health risk or
safety risk.

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

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

J. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

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

    EPA has determined that this final rule will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because it does not
affect the level of protection provided to human health or the
environment. This proposed rule offers the same environmental justice
benefits that were described in the final NPDES eRule preamble in
Section VIII.J. The final rule preamble states that ``[a]s described in
the context of non-monetary benefits, discussed in Section VI and
described below, the final rule would significantly increase
transparency and access to crucial information that is relevant to the
protection of the health and environment of minority, low income, and
tribal populations.'' See 80 FR 64095.

Note 2: Use the ``NPDES Data Group Number'' in this table and the ``NPDES Data Group Number'' column in Table 2
  to identify the source of the required data entry. EPA notes that electronic systems may use additional data
  to facilitate electronic reporting as well as management and reporting of electronic data. For example, NPDES
  permittees may be required to enter their NPDES permit number (``NPDES ID''--NPDES Data Group 1 and 2) into
  the applicable electronic reporting system in order to identify their permit and submit a Discharge Monitoring
  Report (DMR--NPDES Data Group 3). Additionally, NPDES regulated entities may be required to enter and submit
  data to update or correct erroneous data. For example, NPDES permittees may be required to enter new data
  regarding the Facility Individual First Name and Last Name (NPDES Data Group 1 and 2) with their DMR
  submission when there is a facility personnel change.
Note 3: The applicable reporting frequency is specified in the NPDES permit or control mechanism, which may be

Municipal Separate Storm Sewer System (MS4) NPDES Permit-Related Information:
    [Note: Small MS4s seeking coverage under a ``Two-Step General Permit'' issued pursuant to Sec.
     122.28(d)(2) are required to submit to the authorized NPDES program information on stormwater control
     activities they propose to take to address specific requirements. The authorized NPDES program will review
     this information and then establish, through a second permitting step, additional permit terms and
     conditions, as necessary to satisfy the MS4 permit standard, for each MS4. The authorized NPDES programs
     should use their best professional judgement to adequately identify the mandatory set of requirements using
     actual language from the permit, summarized versions of one or more permit requirements, or a mix of actual
     and summarized permit requirements. Any summary of permit requirements should provide a clear understanding
     of the one or more permit requirements. The requirements listed in this section will be used to facilitate
     electronic reporting of the MS4 Program Report.].
