Cross-Media Electronic Reporting

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is establishing the framework by which it will accept 
electronic reports from regulated entities in satisfaction of certain 
document submission requirements in EPA's regulations. EPA will provide 
public notice when the Agency is ready to receive direct submissions of 
certain documents from regulated entities in electronic form consistent 
with this rulemaking via an EPA electronic document receiving system. 
This rule does not mandate that regulated entities utilize electronic 
methods to submit documents in lieu of paper-based submissions. In 
addition, EPA is not taking final action on the electronic 
recordkeeping requirements at this time.
    States, tribes, and local governments will be able to seek EPA 
approval to accept electronic documents to satisfy reporting 
requirements under environmental programs that EPA has delegated, 
authorized, or approved them to administer. This rule includes 
performance standards against which a state's, tribe's, or local 
government's electronic document receiving system will be evaluated 
before EPA will approve changes to the delegated, authorized, or 
approved program to provide electronic reporting, and establishes a 
streamlined process that states, tribes, and local governments can use 
to seek and obtain such approvals.

DATES: This rule shall become effective January 11, 2006.

ADDRESSES: The public record for this rulemaking has been established 
under docket number OEI-2003-0001 and is located in the EPA Docket 
Center, (EPA/DC) EPA West, Room B102, 1301 Constitution Ave., NW., 
Washington, DC. The EPA Docket Center Public Reading Room is open from 
8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays. (See SUPPLEMENTARY INFORMATION below.)

I. Overview

A. Why does the Agency seek to provide electronic alternatives to 
paper-based reporting and recordkeeping?

    In the Federal Register of August 31, 2001 (66 FR 46162), EPA 
published a notice of proposed rulemaking, announcing the goal of 
making electronic reporting and electronic recordkeeping available 
under EPA regulatory programs. The Agency believes that the submission 
and storage of electronic documents in lieu of paper documents can:
     Reduce the cost and burden of data transfer and 
maintenance for all parties to the data exchanges;
     Improve the data and the various business processes 
associated with its use in ways that may not be reflected directly in 
cost-reduction, e.g., through improvements in data quality, and the 
speed and convenience with which data may be transferred and used; and
     Maintain the level of corporate and individual 
responsibility and accountability for electronic reports and records 
that currently exists in the paper environment.

Recent federal policy and law are also strong drivers of electronic 
alternatives to traditional reporting and recordkeeping. The Government 
Paperwork Elimination Act (GPEA) of 1998, Title XVII of Public Law 105-
277, requires the Director of the Office of Management and Budget (OMB) 
to ensure that executive agencies provide for the option of the 
electronic maintenance, submission, or disclosure of information as a 
substitute for paper when practicable, and for the use and acceptance 
of electronic signatures, when practicable. See GPEA section 1704. 
Given the enormous strides in data transfer and management 
technologies, particularly in connection with the Internet, replacing 
paper with electronic data transfer now promises increased productivity 
across almost all facets of business and government.
    In seeking to make electronic alternatives available that were not 
contemplated when most existing EPA regulations were written, EPA was 
mindful of the need to maintain our ability to carry out our statutory 
environmental and health protection mission, in part through ensuring 
the integrity of environmental compliance documents. Accordingly, the 
intended

[[Page 59850]]

effect of the proposed regulation was to permit and encourage the use 
of electronic technologies in a manner that is consistent with EPA's 
overall mission and that preserves the integrity of the Agency's 
compliance and enforcement activities.
    The Agency believes that it is essential to ensure that electronic 
reports can play the same role as their paper counterparts in providing 
evidence of what was reported and to what identified individuals 
certified with respect to the report. Otherwise, electronic reporting 
places at risk the continuing viability of self-monitoring and self-
reporting that provides the framework for compliance under most of our 
environmental programs. The purpose of today's final rule is therefore 
twofold. Today's rule is intended to provide regulated industry, EPA, 
and state, tribe, and local governments with electronic reporting 
alternatives that improve the efficiency, the speed, and the quality of 
regulatory reporting. At the same time, the rule is intended to ensure 
the legal dependability of electronic documents submitted under 
environmental programs. This includes, among other things, ensuring 
that individuals will be held as responsible and accountable for the 
electronic signatures, which they execute, and for the documents to 
which such signatures attest as they currently are in cases of 
documents where they execute handwritten signatures.

B. What does the electronic reporting rule do?

    EPA is announcing today the final regulatory provisions in a new 
part 3 of Title 40 of the CFR for electronic reporting to EPA and under 
authorized state, tribe, and local government programs. ``Authorized 
program'' is shorthand for a federal program that EPA has delegated, 
authorized, or approved a state, tribe or local government to 
administer under other provisions of title 40 of the CFR, where the 
delegation, authorization, or approval has not been withdrawn or 
expired. Section 3.3 of the rule codifies this usage in the regulatory 
text. This use of ``authorized'' does not mean that EPA is precluded 
from an enforcement action by a prior enforcement action being taken by 
a state, tribe, or local government under its authorized program. The 
final rule incorporates changes made after publication of the proposed 
rule that are discussed in detail in section IV of this Preamble. This 
rule establishes electronic reporting as an acceptable regulatory 
alternative across a broad spectrum of EPA programs, and establishes 
requirements to assure that electronic documents are as legally 
dependable as their paper counterparts.
    The requirements in Subpart B of the rule apply to entities that 
choose to submit electronic documents for direct reporting to EPA, 
including state, tribe, and local government facilities that choose to 
submit electronic documents to EPA to satisfy requirements that apply 
to them under other provisions of title 40 of the CFR. However, the 
scope of this final rule excludes any data transfers between EPA and 
states, tribes, or local governments as a part of their authorized 
programs or as a part of administrative arrangements between states, 
tribes, or local governments and EPA to share data. The requirements in 
Subpart D of the rule provide for electronic reporting under authorized 
state, tribe, and local government programs and apply to the 
governmental entities administering the authorized programs. Under the 
final rule, states, tribes, and local governments have the choice of 
using electronic submission rather than paper for reporting under their 
authorized programs. Comments on the proposed rule indicated that some 
states and local governments are now requiring electronic reporting 
under those programs. Existing electronic document receiving systems 
must receive EPA approval in accordance with Subpart D in order to meet 
the requirements of part 3.
    This rule does not require that any document be submitted 
electronically, and it does not require any state, tribe, or local 
authorized program to receive electronic documents. Public access to 
environmental compliance information is not affected by today's action.
    Additionally, the scope of the final rule specifically excludes the 
submission of any electronic document via magnetic or optical media--
for example via diskette, compact disk (CD), digital video disc (DVD), 
or tape--as well as the transmission of documents via hard copy 
facsimile or ``fax.'' The exclusion of magnetic or optical media 
submissions from the scope of this rule in no way indicates EPA's 
rejection of these technologies as a valid approach to paperless 
reporting. Magnetic and optical media submissions fulfill the goal of 
providing alternatives to submission on paper. EPA has already 
successfully implemented a paperless reporting alternative that 
utilizes magnetic and optical media submissions to fulfill many 
regulatory reporting requirements. Such instances include reporting 
related to the hazardous waste, Toxic Release Inventory, and pesticide 
registration programs. EPA expects these magnetic and optical media 
approaches to paperless reporting to continue, and nothing in today's 
rule should be interpreted to proscribe or discourage them.
    For entities that report to EPA directly and do so by submitting 
electronic documents, today's action requires that these documents be 
submitted either to the Agency's centralized electronic document 
receiving system, called the ``Central Data Exchange'' (CDX), or to 
alternative systems designated by the Administrator as described herein 
and in a separate Federal Register notice. Entities that submit 
electronic documents directly to EPA will satisfy the requirements in 
today's rule by successfully submitting their reports to one of these 
systems. While we do not intend to codify any of the details of how CDX 
operates or how it is constructed, the characteristics of the CDX and 
the submission scenarios are described later in this Preamble. In 
addition, the CDX design specifications are included as a part of this 
rulemaking docket.
    Many facilities submit documents directly to states, tribes, or 
local governments under authorized programs. For currently authorized 
programs that receive or wish to begin receiving electronic documents 
in lieu of paper, this rule requires EPA approval of program revisions 
or modifications that address their electronic reporting 
implementations. For programs initially seeking authorization, this 
rule requires EPA approval of any electronic reporting components of 
the programs. In both cases, EPA approval will be based largely on an 
assessment of the program's ``electronic document receiving system'' 
that is or will be used to implement electronic reporting. For this 
purpose, this rule includes performance-based standards that EPA will 
use to determine that an electronic document receiving system is 
acceptable. To implement electronic reporting under currently 
authorized programs, EPA is creating a streamlined procedure that 
states, tribes, and local governments may use to revise or modify their 
authorized programs to incorporate electronic reporting. Today's 
rulemaking also includes special provisions for authorized programs' 
electronic document receiving systems that exist at the time of 
publication of this final rule.
    It is worth noting that EPA can approve changes to authorized 
state, tribe, or local programs that involve the use of CDX to receive 
data submissions from their reporting communities, and EPA is exploring 
opportunities to

[[Page 59851]]

leverage CDX resources for use by states, tribes, and local 
governments. As currently implemented, CDX provides the major systems 
infrastructure components necessary to achieve electronic reporting 
consistent with the standards in this rule for assessing state, tribe, 
or local government electronic document receiving systems. 
Additionally, EPA has set the goal of making CDX operations fully 
consistent with the requirements in today's rule within two years.
    While today's rule establishes electronic reporting as a regulatory 
alternative, EPA will make the electronic submission alternative 
available for specific reports or other documents only as EPA announces 
its readiness to receive them through CDX or another designated system. 
EPA will publish announcements in the Federal Register as CDX and other 
systems become available for particular environmental reports. These 
elements are discussed in more detail in section V of this Preamble.
    In a notice published concurrently with today's rule, EPA clarifies 
the status of electronic reporting directly to EPA systems that exist 
as of the rule's publication date. In accordance with 40 CFR 3.10, EPA 
is designating for the receipt of electronic submissions, all EPA 
electronic document receiving systems currently existing and receiving 
electronic reports as of the date of the notice. This designation is 
valid for a period of up to two years from the date of publication of 
the notice. During this two-year period, entities that report directly 
to EPA may continue to satisfy EPA reporting requirements by reporting 
to the same systems as they did prior to CROMERR's publication unless 
EPA publishes a notice that announces changes to, or migration from, 
that system. Any existing system continuing to receive electronic 
reports at the expiration of this two-year period must receive 
redesignation by the Administrator under Sec.  3.10. Notice of such 
redesignation will be published in the Federal Register.

C. What is the status of the proposed electronic recordkeeping 
provisions?

    At this time, EPA is only finalizing the provisions for electronic 
reporting to EPA and under authorized programs. The August 31, 2001, 
proposal, however, also addressed records that EPA or authorized 
programs require entities to maintain under any of the environmental 
programs governed by Title 40 of the CFR or related state, tribe, and 
local laws and regulations. For such records, EPA proposed specific 
provisions for administering the maintenance of electronic records 
under these environmental regulations. EPA proposed criteria under 
which the Agency would consider electronic records to be trustworthy, 
reliable, and generally equivalent to paper records in satisfying 
regulatory requirements. For entities that choose to keep records 
electronically, the proposal would have required the adoption of best 
practices for electronic records management. For facilities maintaining 
records to satisfy the requirements of authorized programs, the 
proposal would have allowed for EPA approval of changes to the 
authorized programs to provide for electronic recordkeeping. Under the 
proposal, approval would have been based on a determination that the 
authorized program would require best practices for electronic records 
management, corresponding to EPA's provisions for electronic records 
maintained to satisfy EPA recordkeeping requirements.
    Further, EPA proposed that once the rule took effect, any records 
subject to the rule that were maintained to satisfy the requirements of 
EPA programs could only be maintained electronically after EPA 
announced in the Federal Register that EPA was ready to allow 
electronic records maintenance to satisfy the specified recordkeeping 
requirements. Also under the proposal, records maintained under an 
authorized state, tribe, or local government program could only be 
maintained electronically once EPA had approved the necessary changes 
to the authorized program.
    Based on the comments received on the proposed electronic 
recordkeeping provisions, EPA reconsidered its approach to electronic 
recordkeeping and is not issuing final recordkeeping rules at this 
time. The Agency is conducting additional analysis and intends to 
publish a supplemental notice or re-proposal to solicit additional 
comments before a final rule on electronic recordkeeping is issued. We 
will be reviewing provisions related to the methods used to ensure 
accuracy, accessibility and the ability to detect alterations of 
records stored electronically, as well as other possible controls for 
electronic recordkeeping. The Agency intends to utilize this review to 
engage states, tribes, local governments, and industry in meaningful 
consultation to ensure that the EPA has the best available information 
on which to base its decisions. In conjunction with these 
consultations--and before issuing any notice or re-proposal--EPA will 
conduct additional analysis on the costs and benefits of alternative 
approaches, and the technical feasibility of various options, with a 
focus on impacts to small businesses. Today's rule does not authorize 
the conversion of existing paper documents retained to comply with 
existing recordkeeping requirements under other provisions of Title 40 
of the CFR to an electronic format for record-retention purposes.

D. How were stakeholders consulted during the development of today's 
final rule?

    This final rule reflects more than ten years of interaction with 
stakeholders that included states, tribes, and local governments, 
industry groups, environmental non-government organizations, national 
standard setting committees, and other federal agencies. As detailed in 
the proposal, many of our most significant interactions involved 
electronic reporting pilot projects conducted with state agency 
partners, including the States of Pennsylvania, New York, Arizona, and 
several others. In May, 1997, work began with approximately 35 states 
on the State Electronic Commerce/Electronic Data Interchange Steering 
Committee (SEES) convened by the National Governors' Association (NGA) 
Center for Best Practices (CBP). Also, EPA sponsored a series of 
conferences and meetings, beginning in June, 1999, with the explicit 
purpose of seeking stakeholder advice before drafting the proposal. 
Reports of these conferences and meetings are available in the docket 
for this rulemaking, along with the product of the SEES effort, a 
document entitled, ``A State Guide for Electronic Reporting of 
Environmental Data,'' and reports on some of the more recent state/EPA 
electronic reporting pilots.
    For the proposal, EPA provided a 6-month public comment period, 
which closed on February 27, 2002. During that time, we received 184 
sets of written comments on the proposed rule. The commenters 
represented a broad spectrum of interested parties: States, local 
governments, specific businesses, trade associations, and other federal 
agencies. Substantive changes to the electronic reporting provisions 
based on public comments are discussed in detail in section IV of this 
Preamble. In addition, EPA received comments at four public meetings 
held around the country and at two meetings with states held in 
Washington, DC. The comments and meeting summaries can be found in the 
docket to this rulemaking. Today's final rule reflects many of the 
comments and concerns raised by commenters on the proposal. (A complete 
discussion of the options considered by EPA and other background 
information on the Agency's policy on electronic reporting

[[Page 59852]]

can be found in the proposed rule.) The majority of comments focused on 
the costs and burden of the proposed Subpart D electronic recordkeeping 
provisions. EPA's response to public comments to the proposal can be 
found in the rulemaking docket, in the Response to Comments document.

E. What alternatives to today's final rule did EPA consider?

    EPA considered both a more stringent and a less stringent 
alternative to the regulatory approach taken in this rule. The more 
stringent alternative is reflected in the electronic provisions 
published, August 31, 2001, in the Notice of Proposed Rulemaking for 
CROMERR. The proposed version of CROMERR was more stringent by virtue 
of setting much more prescriptive, detailed requirements that 
electronic document receiving systems would have to satisfy. For 
example:
     Proposed Sec.  3.2000(d) contained very specific 
requirements for submitter identity management that a system would have 
to satisfy, including detailed requirements for renewal of registration 
and revocation of registration under specified circumstances;
     Proposed Sec.  3.2000(e) contained very detailed 
requirements for the signature/certification scenario that a system 
would have to provide for, specifying the exact sequence of steps to be 
followed in electronically signing a submission, and requiring such 
features as on-screen, scroll-through presentation of the data to be 
submitted for review of the signatory prior to signing.
    EPA received significant public comment on this approach, both from 
states and from regulated companies, and there were at least three 
closely related themes. The first was that such prescriptive 
requirements would greatly limit the flexibility of states to implement 
electronic reporting in a cost-effective way. The second theme was that 
many of the requirements--especially those specifying the signature/
certification scenario--were not appropriate to many cases where 
electronic reporting would occur. Third and finally, many of these 
commenters expressed skepticism that these very detailed requirements 
represented the only possible approach to ensuring the legal 
dependability of electronic submissions and signatures. These themes 
are discussed in detail in section IV.B of this Preamble.
    EPA also considered a less stringent alternative that would have 
refrained from specifying requirements to establish the identity of an 
individual to whom a signature device or credential (e.g. a PIN, 
password, or PKI certificate) is issued. This less stringent 
alternative would have omitted the provision for identity-proofing in 
the final Sec.  3.2000(b)(5)(vii). In terms of regulatory impact, this 
would be a significant reduction in stringency. Most of the burden on 
regulated entities imposed by today's rule is associated with the 
registration process involved in obtaining a signature device or 
credential, and any requirement to establish the registrant's identity 
raises the aggregate burden substantially.
    EPA rejected this less stringent alternative, because we believe 
that it would seriously undermine the rule's ability to assure the 
legal dependability of electronic submissions. It is a basic principle 
of electronic authentication (E-authentication) that individuals being 
authenticated are who they say they are. E-authentication depends 
critically on the degree of trust we can place in the credential the 
individual presents, and such trust depends heavily on the process of 
establishing the individual's identity (or ``identity-proofing'') when 
he or she first registers for the credential. If the identity-proofing 
process is not sufficiently stringent and credible, then it may be 
uncertain who is using the credential in a specific instance where it 
is presented. Where the credential is used to create an electronic 
signature, inadequate identity-proofing may create uncertainty as to 
who the signatory is, as a result, the signature may be rendered 
undependable for any legal purpose. Accordingly, EPA believes that, 
notwithstanding the cost, it is necessary to specify that identity-
proofing be conducted. The Sec.  3.2000(b)(5)(vii) identity-proofing 
requirement is explained in detail in section VI.E.12 of this Preamble.

II. Background

A. What has been EPA's electronic reporting policy?

    On September 4, 1996, EPA published a document entitled ``Notice of 
Agency's General Policy for Accepting Filing of Environmental Reports 
via Electronic Data Interchange (EDI)'' (61 FR 46684) (hereinafter 
referred to as `the 1996 Policy'), where ``EDI'' generally refers to 
the transmission, in a standard syntax, of unambiguous information 
between computers of organizations that may be completely external to 
each other. This notice announced EPA's basic policy for accepting 
electronically submitted environmental reports, and its scope was 
intended to include any regulatory, compliance, or informational 
(voluntary) reporting to EPA via EDI.
    For purposes of the 1996 policy, the standard transmission formats 
used by EPA were to be based on the EDI standards developed and 
maintained by the American National Standards Institute (ANSI) 
Accredited Standards Committee (ASC) X12. By linking our approach to 
the ANSI X12 standards, we hoped to take advantage of the robust ANSI-
based EDI infrastructure already in place for commercial transactions, 
including a wide array of commercial off-the-shelf (COTS) software 
packages and communications network services, and a growing industry 
community of EDI experts available both to EPA and to the regulated 
community. At the time EPA was writing this policy, ANSI-based EDI was 
arguably the dominant mode of electronic commerce across almost all 
business sectors, from aerospace to wood products, at least in the 
United States. (A complete discussion of EPA's 1996 policy can be found 
in the preamble to the proposed rule.)
    With this final rule, EPA is making changes to the 1996 policy for 
three primary reasons. First, and most important, the technology 
environment has changed substantially since the 1996 policy was 
written. Web-based electronic commerce and public key infrastructure 
(PKI) are two examples. While both were available and in use for some 
purposes in 1996, they had not yet achieved the level of acceptance and 
use that they enjoy today. We could not have anticipated in 1996 that 
this evolution would occur as rapidly as it has. Clearly, these 
developments require that we extend our approach to electronic 
reporting beyond EDI and Personal Identification Numbers (PINs). In 
addition, they teach us that it is generally unwise to base regulatory 
requirements on the existing information technology environment or on 
assumptions about the speed and direction of technological evolution.
    Second, we believe that technology-specific provisions would be 
very complex and unwieldy. The resulting regulation would likely place 
unacceptable burdens on regulated entities trying to understand and 
comply.
    Third, and finally, an electronic reporting architecture that makes 
a centralized EPA or state system the platform for such functions as 
electronic signature/certification is now quite viable--and quite 
consistent with the standard practices of Web-based electronic 
commerce. Given the state of technology six years ago, we could not

[[Page 59853]]

have considered this approach in the 1996 policy.

B. How does today's final rule change EPA's electronic reporting 
policy?

    For practical purposes, the most important change that today's rule 
makes is in our technical approach to electronic reporting. In contrast 
to the 1996 policy, today's rule does not generally specify or limit 
the range of allowable electronic submission technologies and formats. 
Under today's rule, complaint electronic reporting approaches can 
include user-friendly `smart' electronic forms to be completed on-line 
or downloaded for completion off-line at the user's personal computer, 
as well as data transfers via the Internet or secure email in a variety 
of standard and common off-the-shelf, application-based formats. 
Similarly, in terms of electronic signature technology, the rule allows 
for a range of approaches, including various implementations of PINs 
and passwords, the use of private or personal information, digital 
signatures based on PKI certificates, and other signature technologies 
as they become viable for our applications. As EPA or authorized 
programs implement electronic submission for specific reports, the rule 
allows them to select one or more of the available submission and 
signature approaches according to their circumstances and the program-
specific requirements.
    EPA's goals are to make this electronic reporting alternative as 
simple, attractive and cost-effective as possible for reporting 
entities, while ensuring that electronically submitted documents are as 
legally dependable as their paper counterparts. We believe that today's 
rule achieves these goals, but--unlike the 1996 policy--without 
requiring specific technologies or setting detailed procedural steps 
for the submission of electronic documents. Our strategy--as initially 
set out in the August 31, 2001, notice of proposed rulemaking, and as 
finalized today--is to impose as few specific requirements as possible 
on reporting entities, and to generally keep requirements neutral with 
respect to technology. As a consequence, today's rule enables EPA, the 
states, tribes, and local governments to offer regulated companies 
diverse approaches to electronic reporting that can be tailored to 
their technical capabilities and to the level of automation they wish 
to achieve. In addition, the strategy gives EPA, the states, tribes, 
and local governments the flexibility to adapt electronic reporting 
systems to evolving technologies without requiring that regulations be 
amended with each technological innovation.
    However, this regulatory strategy does not mean abandoning any 
control over how electronic documents are submitted. In place of 
specific technologies or detailed procedural steps, today's rule 
requires that electronic submissions be made to CDX or other designated 
EPA systems, or to state, tribe, or local government systems that are 
determined to satisfy a certain specified set of technology-neutral 
performance standards. As a practical matter, the use of these systems 
(e.g., CDX or others that meet the specified performance standards) 
will involve submission procedures that we believe are sufficient to 
ensure the legal dependability of electronic reports so that they meet 
the needs of our compliance and enforcement programs. In addition, 
while the specified performance standards may be technology-neutral, 
agency electronic reporting systems that implement the standards will 
incorporate suites of very specific technologies that will further 
determine the process for actual electronic submission. Sections V.B 
and V.C of this Preamble describe these requirements and the associated 
technologies in some detail for the case of reporting directly to EPA 
via CDX.

III. Scope of the Electronic Reporting Rule

    EPA is today promulgating a new Part 3 in Title 40 of the CFR. The 
new Part applies to all persons who submit reports or other documents 
to EPA under Title 40, and to state, tribe, and local programs that 
administer or seek to administer authorized programs under Title 40. 
The new part 3 does not address contracts, grants or financial 
management regulations contained in Title 48 of the CFR.

A. Who may submit electronic documents?

    Any entity that submits documents addressed in this rule (see 
section III.B., below) directly to EPA can submit them electronically 
as soon as EPA announces that CDX or a designated alternative system is 
ready to receive these reports. (See section V of this Preamble for a 
discussion on requirements for electronic reporting to EPA, and section 
V.B for a discussion of the status of electronic reporting directly to 
EPA systems that exist as of the rule's publication date.) Under this 
rule, the affected entities may elect to utilize the electronic 
reporting alternative. These entities are not required by this final 
rule to report electronically; however, they may be required to report 
electronically under other Title 40 regulations, and nothing in today's 
rule limits EPA's ability to require electronic reporting under other 
parts of Title 40.
    In general, entities may submit documents electronically as 
provided for under authorized state, tribe, or local government 
programs. Nothing in this rule prohibits state, tribe, or local 
governments from requiring electronic reporting under applicable state, 
tribe, or local law.

B. Which documents can be filed electronically?

    This rule addresses document submissions required by or permitted 
under any EPA or authorized state, tribe, or local program governed by 
EPA's regulations in Title 40 of the CFR. Nonetheless, EPA will need 
time to develop the hardware and software components required for each 
individual type of document. Similarly, states, tribes, and local 
governments will need time to evaluate their electronic document 
receiving systems to ensure that they meet the standards promulgated in 
today's final rule. Accordingly, once this rule takes effect, specific 
documents submitted directly to EPA that are not already being 
submitted electronically to existing EPA systems can only be submitted 
electronically after EPA announces in the Federal Register that CDX or 
an alternative system is ready to receive those specific documents. 
(See section V.B of this Preamble for a discussion of the status of 
electronic reporting directly to EPA systems that exist as of the 
rule's publication date.) Documents may be submitted electronically 
under the provisions of an authorized state, tribe, or local program.

C. How does this final rule implement electronic reporting?

    The new 40 CFR part 3 consists of four (4) Subparts. Subpart A 
provides that any requirement in Title 40 to submit a report directly 
to EPA can be satisfied with an electronic submission that meets 
certain conditions (specified in Subpart B) once the Agency publishes a 
notice that electronic document submission is available for that 
requirement. Subpart A also provides that electronic reporting can be 
made available under EPA-authorized state, tribe, or local 
environmental programs. In addition, Subpart A makes clear: (1) that 
electronic document submission, while permissible under the terms of 
this rule, is not required by any provision of this rule; and (2) that 
this rule confers no right or privilege to submit data electronically 
and does not obligate EPA or states, tribes, or local

[[Page 59854]]

agencies to accept electronic data. Subpart A also contains key 
definitions and discusses compliance and enforcement.
    Subpart B sets forth the general requirements for acceptable 
electronic documents submitted to EPA. It provides that electronic 
documents must be submitted either to CDX or to other EPA designated 
systems. It also includes general requirements for electronic 
signatures. The requirements in Subpart B apply to entities that submit 
electronic documents for direct reporting to EPA, including states, 
tribes, and local governments that submit electronic documents to EPA 
to satisfy requirements that apply to them under Title 40 of the CFR. 
Subpart B does not apply to any data transfers between EPA and states, 
tribes, or local governments as a part of their authorized programs or 
as a part of administrative arrangements between states, tribes, or 
local governments and EPA to share data. Additionally, Subpart B does 
not apply to the submission of any electronic document via magnetic or 
optical media--for example via diskette, compact disk, or tape--or to 
the transmission of documents via hard copy facsimile or ``fax.''
    Subpart C is reserved for future EPA electronic recordkeeping 
requirements.
    Finally, Subpart D sets forth the process and standards for EPA 
approval of changes to authorized state, tribe, and local environmental 
programs to allow electronic reporting to satisfy requirements under 
these programs. Again, for purposes of Subpart D, ``electronic 
reporting'' entails submission via telecommunications, and Subpart D 
requirements do not apply in cases of submission via magnetic or 
optical media or hard copy ``fax.'' With respect to electronic 
reporting, Subpart D includes simplified performance-based standards 
for acceptable state, tribe, or local agency electronic document 
receiving systems against which EPA will assess authorized program 
electronic reporting elements. It also provides a streamlined process 
for approving applications for revisions to authorized programs for 
electronic reporting.
    Given the provisions of Subpart A, a regulated entity wishing to 
determine whether electronic reporting directly to EPA was available 
under some specific regulation will have to verify that EPA has 
published a Federal Register notice announcing their availability and 
will have to locate any additional provisions or instructions governing 
the electronic alternative for the particular reporting requirement. To 
facilitate this determination, EPA intends to maintain an easily 
accessed list of EPA reports for which electronic reporting has been 
implemented--cross-referencing the applicable Federal Register 
notices--on the Exchange Network and Grants webpage at http://www.epa.gov/exchangenetwork
.


IV. Major Changes From Proposed Electronic Reporting Provisions

A. How does the rule streamline the approval of electronic reporting 
under authorized state, tribe, and local government programs?

    1. Review of the proposal. EPA proposed that states, tribes, and 
local governmental entities would use the procedures for program 
revision or modification provided in existing program-specific 
regulations governing state, tribe, or local authorized programs.
    In the Preamble to the proposed rule, we noted that our approach 
raised certain administrative concerns, especially in cases where a 
governmental entity wished to use a single system to accept electronic 
submissions across a number of authorized programs, corresponding to 
EPA's use of CDX to receive reports across EPA programs. To receive EPA 
approval for such implementations, the governmental entity would have 
to apply for revision or modification under each authorized program 
affected, using procedures that might vary substantially from program 
to program. While these procedures might vary, each substantive review 
would still refer to the same proposed part 3 criteria, and--in the 
case of a single system implementation--would apply these criteria to 
the same system. EPA intended this approach to facilitate an 
administrative streamlining of the approval process, by allowing a 
single EPA review of all cross-program applications associated with a 
particular electronic document receiving system, which would enable EPA 
to make a single decision to approve or disapprove all the associated 
applications. While this approach would not eliminate multiple 
applications, it would at least simplify the interactions between the 
applicant and EPA during substantive review, and would speed EPA action 
on the applications themselves.
    EPA also considered more radical streamlining alternatives, 
including a centralized approval process provided for by regulation, 
and the proposal requested comment on whether any of these alternatives 
would be preferable to the administrative approach to streamlining.
    2. Comments on the proposal. In comments on the provisions for 
electronic reporting under authorized programs, a recurring theme was 
the complexity of the proposed requirements for EPA approval of program 
revisions or modifications to allow electronic reporting. The comments 
in many cases seemed directed equally to the approval process and to 
the proposed criteria for approval. Comments on the criteria are 
discussed in more detail in section IV.B.2 of this Preamble.
    As for the comments that clearly addressed the process, there were 
two major concerns. The first was that the process, due to the various 
current program authorization regulations, is inherently complicated, 
time-consuming and resource-intensive. In a few cases, commenters noted 
the particular worry that having to seek EPA approval for each program 
implementing electronic reporting would be especially burdensome, and 
that EPA's proposed approach of streamlining the internal review 
component of the program revision process would be of little help.
    The second concern was the impact of the rule on electronic 
reporting that was already underway. Commenters noted that many 
authorized programs are already accepting electronic submissions, or 
would be by the time the final rule is published, and they worried 
about the timing of the requirement that the electronic document 
receiving systems they use for this purpose be approved by EPA under 
associated program revision or modification procedures. Under the 
proposed provisions, such systems would have to be EPA-approved as soon 
as the rule became effective, which was not practicable. Given the need 
to address the criteria for approval, such applications could only be 
initiated once the rule was finalized, and they might take months to 
complete and get approved, or substantially longer in cases where the 
revision or modification required state legislative or regulatory 
changes. During the months or years that the revision or modification 
was in process, the authorized program would either have to shut down 
their electronic document receiving systems or, of necessity, operate 
them out of compliance with the rule. Commenters were particularly 
concerned with the disruptive impacts of having to shut these systems 
down. They pointed out that reversion to paper-based submissions in 
such cases may be difficult and expensive, both for the agencies and 
for the submitting entities that are affected, and that resuming

[[Page 59855]]

system operation after a long hiatus may require resources more 
typically associated with system start-up. Additional comments on 
program revision or modification and EPA's responses can be found in 
the rulemaking docket, in the Response to Comments document.
    3. Revisions in the final rule. To address the concern that the 
proposed program revision or modification to accommodate electronic 
reporting was too complicated and burdensome, the final rule provides 
streamlined procedures for adding electronic reporting to existing 
authorized programs. These are optional procedures that a state, tribe, 
or local government may use if it chooses, in place of the applicable 
program-specific procedures, to seek EPA approval for revisions or 
modifications that provide for electronic reporting. EPA believes that 
in most cases these optional procedures will be substantially simpler 
and quicker than their program-specific alternatives. These new 
procedures are discussed in detail in section VI.C of this Preamble.
    To address the concern that the required program revisions or 
modifications may disrupt authorized programs that already have 
electronic reporting underway, the final rule provides for a two-year 
delayed compliance date--in effect, a two-year ``grace period''--before 
such programs have to submit their applications for revision or 
modification. Programs will be allowed this grace period where they 
have systems that fit the definition of ``existing electronic document 
receiving system,'' explained in section VI.B.2 of this Preamble. In 
addition, these provisions allow the grace period to be extended, on a 
case-by-case basis, where an authorized program may need to wait for 
legislative or regulatory changes before a complete application can be 
submitted.

B. How has EPA revised the requirements that state, tribe, and local 
government electronic reporting programs must satisfy?

    1. Review of the proposal. EPA proposed a detailed set of criteria 
that would have to be met by any system that is used to receive 
electronic documents submitted to satisfy document submission 
requirements under any EPA-authorized state, tribe, or local 
environmental program. The proposed criteria addressed the capabilities 
that EPA believed a state, tribe, or local government's electronic 
document receiving system must have regarding six function-specific 
categories: (1) System security, (2) electronic signature method, (3) 
submitter registration, (4) signature/certification scenario, (5) 
transaction record, and (6) system archives.
    These criteria were based upon EPA's consideration of the roles 
that many electronically submitted documents will likely play in 
environmental program management, including compliance monitoring and 
enforcement, and the need to ensure that such roles were not 
compromised by the transition from paper to electronic submission. In 
many respects electronic submission enhances a document's utility for 
environmental programs: it significantly reduces the resources and time 
involved in making the content available to its users, and can greatly 
facilitate data quality assurance and analysis. Nonetheless, electronic 
submissions may also be open to challenge, primarily with respect to 
their authenticity, and particularly where they are used to establish 
the actions and intentions of the submitters. We normally consider such 
uses in the case of environmental reporting, especially where 
electronic submissions are made to report on an entity's compliance 
status and where the submission includes a responsible individual's 
certification to the truth of what is reported. For such cases, EPA 
identified a programmatic need to be able to authenticate the 
submission content and the certification--for example, to be able to 
address issues of fraud or false reporting where they arise--and it is 
primarily this need that was addressed by the six proposed criteria.
    The point of the proposal's six function-specific categories was to 
ensure the authenticity of electronic documents submitted in lieu of 
paper reports, so that they will be able to play the same role as their 
paper counterparts in providing evidence of what was reported and to 
what an identified individual certified with respect to the report. For 
example, in the case of paper submissions, the evidence surrounding a 
handwritten signature is normally sufficient to demonstrate that the 
signature is authentic and rebut any attempt by the signatory to 
repudiate it and EPA intends the standards in today's rule to provide 
evidence for electronic signatures that has a corresponding level of 
non-repudiation. Since these evidentiary issues typically arise in the 
context of judicial or other legal proceedings, electronic documents 
need the same ``legal dependability'' as their paper counterparts. The 
over-arching standard in the concept of ``legal dependability'' is that 
any electronic document that may be used as evidence to prosecute an 
environmental crime or to enforce against a civil violation should have 
no less evidentiary value than its paper equivalent. For example, where 
there is a question of deliberate falsification of compliance data--it 
must be possible to establish the signatory's identity beyond a 
reasonable doubt no matter whether the submission was electronic or 
paper.
    A seventh, more general proposed criterion, entitled ``Validity of 
Data,'' addressed the standard of legal dependability directly. The 
idea, in general, was that a system used to receive electronic 
documents must be capable of reliably generating evidence for use in 
private litigation, in civil enforcement proceedings, and in criminal 
proceedings in which the standard for conviction is proof beyond a 
reasonable doubt that the electronic document was actually signed by 
the individual identified as the signatory and that the data it 
contains was not submitted in error. The six more detailed, function-
specific criteria represented the requirements for satisfying this more 
general ``Validity of Data'' criterion. Taken together, the seven 
proposed criteria were intended to ensure the legal dependability of 
electronically submitted documents by providing:
     Standards for valid electronic signatures and authentic 
electronic documents to be admitted as evidence in a judicial 
proceeding;
     Assurance that electronic documents can be authenticated 
to provide evidence of what an individual submitted and/or attested to; 
and
     Assurance that electronic signatures resist repudiation by 
the signatory.

By providing for these and other facets of an electronic document's 
legal dependability, proposed CROMERR was intended to preserve the 
ability of EPA and its authorized programs to hold individuals 
accountable when they certify, attest or agree to the content of 
compliance reports under environmental laws and statutes. By the same 
token, proposed CROMERR was also intended to ensure that EPA and its 
authorized programs will have the documentary evidence they need to 
bring actionable cases of false or fraudulent reporting into court.
    2. Comments on the proposed criteria for electronic document 
receiving systems. EPA received a substantial number of comments on the 
proposed criteria for state, tribe, and local electronic document 
receiving systems, both in written submissions and at meetings with the 
public and with state and local government officials. While a

[[Page 59856]]

few of these comments questioned the ``Validity of Data'' criterion, 
the great majority dealt with the detailed function-specific criteria. 
There were at least three recurring and closely related themes. First, 
the criteria were too prescriptive and inflexible, and would prevent 
state, tribe, and local agencies from adapting their electronic 
reporting approaches to their needs and changing circumstances, and 
foreclose new and creative ways to achieve legal dependability. Second, 
the criteria would make electronic reporting unnecessarily complex, 
costly, and burdensome. Third, while the criteria might be appropriate 
for some cases, the ``one size fits all'' approach was not workable for 
all reports in all programs.
    Commenters tended to associate these three themes with certain 
misperceptions about the proposed requirements for signature method and 
the signature/certification scenario. Concerning signature method, a 
common concern was that the criteria would require states to implement 
PKI-based digital signatures. Commenters generally appear to have 
inferred this from proposed Sec.  3.2000(c) Electronic Signature 
Method, together with EPA's own choice of PKI for some submissions to 
CDX, as discussed in the Preamble. Whatever EPA's plans for CDX, state, 
tribe, and local government systems do not have to conform to the CDX 
model. Implementing a particular system of necessity requires the 
choice of specific technologies. To make those choices does not imply 
that these are the only possible choices that would satisfy whatever 
requirements the rule places on electronic reporting systems. 
Concerning Sec.  3.2000(c), commenters tended to focus on paragraph (5) 
of this section, which stated that the signature method had to ensure 
``that it is impossible to modify an electronic document without 
detection once the electronic signature has been affixed.'' EPA did not 
intend for this provision to establish PKI-digital signature as the 
required signature method. Given current technology, approaches to 
satisfying the Sec.  3.2000(c)(5) requirement frequently involve the 
computation of a number--called a ``hash''--that has a unique relation 
to the content of the electronic document such that any change to the 
document content would change the computed hash. Given the hash, the 
associated document can be confirmed as unmodified at any time by 
calculating a new hash and showing that the new and original hashes are 
identical. Using such a hash-based approach, it is important to ensure 
that the hash has been secured from tampering, and encryption is 
probably the most straightforward way to do this. Encryption can be 
accomplished in a number of ways. Approaches include PKI-based digital 
signature, digital signature where the asymmetric key-pair is not 
associated with a PKI certificate, and various forms of symmetric-key 
cryptography. Additionally, it may be possible to avoid cryptography 
altogether by storing the hash value in a system with appropriately 
controlled access. Thus, a solution using PKI-based digital signatures 
represents only one among a number of possible approaches to satisfying 
the proposed Sec. 3.2000(c)(5) requirement.
    A number of commenters also misinterpreted the criteria under 
proposed Sec.  3.2000(e) Electronic signature/certification scenario 
(especially the provisions for signatory's review of data under Sec.  
3.2000(e)(1)(i)) as requiring signatories to scroll through their 
submissions on-screen before they affix their electronic signatures, 
and requiring state systems to enforce this required ``scroll-
through''. However, the proposal provided not that the signatory must 
review the data on-screen, but rather that he or she be given the 
opportunity to do so. The example of the enforced on-screen ``scroll-
through'' then envisioned for CDX, and provided in the CDX section of 
the proposal's preamble, was in error. EPA did not intend to require 
this ``scroll-through'' of submitted data prior to signature. EPA 
certainly does expect and encourage reporting entities to review data 
intended for electronic submission prior to signature, but does not 
mandate this or any other particular mode or method of signatory review 
in today's rule.
    Returning to the three comment themes--of prescriptiveness, cost 
and burden, and a ``one size fits all'' approach--commenters who raised 
the prescriptiveness issue generally argued that, even supposing that 
there were no specific objections to the detailed Sec.  3.2000 
provisions, EPA had failed to make the case that every single 
requirement under these provisions is necessary to ensure the legal 
dependability of electronic submissions. Commenters who argued that the 
proposed rule would be too costly and burdensome generally focused on 
Sec.  3.2000(c)(5) and Sec.  3.2000(e)(1)(i), discussed above, or on 
the proposed Sec.  3.2000(d) registration and signature agreement 
provisions. There were many comments to the effect that the complex 
Sec.  3.2000(d) registration and re-registration requirements would 
pose substantial barriers to regulated company participation in 
electronic reporting and involve unacceptable expenses for implementing 
agencies. Commenters also noted that the required Sec.  3.2000(e)(1)(i) 
would be difficult to integrate with company workflow practices in many 
cases. Finally, there is the ``one size fits all'' issue. Some of the 
comments raised this as another version of the ``prescriptiveness'' 
issue, but adding that the proposal developed just one model of 
electronic reporting and attempted to make it fit the differing 
circumstances of the various state, tribe, and local agencies that 
would have to comply. Other comments emphasize the point that the 
proposal takes requirements apparently tailored to assuring an 
electronic document's authenticity and applies them to all cases of 
electronic reporting, whether or not the question of authenticity is 
likely to arise.
    EPA has considered these and related comments in writing today's 
rule. We do not wish to set overly prescriptive requirements and so 
foreclose acceptable electronic reporting alternatives that could offer 
equivalent or better assurance of legal dependability while, perhaps, 
being easier for a state, tribe, or local agency to implement. We do 
not wish to set requirements that impose unnecessary costs or burdens. 
And, while we do not see a ``bright line'' around the universe of cases 
where document authenticity might be of concern, we also do not wish to 
address authenticity with requirements that leave states, tribes, and 
local governments with too little flexibility in how they may adapt 
their electronic reporting implementations to their particular 
circumstances. Accordingly, EPA has decided to finalize criteria for 
electronic document receiving systems that directly articulate the 
underlying goal of assuring the legal dependability of electronic 
documents authenticity, and to add more specific requirements only to 
the extent that they are needed to achieve this underlying goal. 
Accordingly, the provisions of today's rule have been clarified as 
general performance standards necessary to ensure the legal 
dependability of the electronic documents they receive. Additional 
comments on the proposed criteria and EPA's responses can be found in 
the rulemaking docket, in the Response to Comments document.
    3. Revisions to the criteria in the final rule. In today's final 
rule, we intend to fulfill the underlying goal of the proposed Sec.  
3.2000 criteria for electronic document receiving systems. This is to 
assure the authenticity and non-

[[Page 59857]]

repudiation of electronic documents submitted in lieu of paper reports, 
so that they are as legally dependable--that is, as admissible in 
evidence and accorded the same evidentiary weight--as their paper 
counterparts. As noted earlier, this goal was expressed most directly 
in the proposed Sec.  3.2000(b) ``Validity of Data'' criterion. 
Accordingly, for the final rule, we started with the proposed Sec.  
3.2000(b) and then clarified the remaining proposed Sec.  3.2000 
criteria as general performance standards for electronic document 
receiving systems, which were incorporated as needed to assure the 
legal dependability of the electronic documents such systems receive. 
The resulting Sec.  3.2000(b) in the final electronic reporting rule 
reflects the requirements discussed in the table below. The citation 
for the corresponding language in the proposed rulemaking is also 
provided.

Proposed Sec.   3.2000(d)(1)-(3),        Section 3.2000(b)(5)(vii)

                                          documents that the system
                                          receives, that the system be
                                          able to establish the identity
                                          of the individual uniquely
                                          entitled to use that device
                                          and his or her relation to the
                                          entity on whose behalf he or
                                          she signs the documents.
------------------------------------------------------------------------

    The requirements in Sec.  3.2000(b)(5)(iii)-(iv) of today's rule, 
concerning ``opportunity to review,'' do not place the responsibility 
for providing an opportunity, or for showing whether or not an 
opportunity was actually taken, on the state, tribe, or local 
government electronic document receiving system. What is required is 
that the system provide evidence sufficient to show that an opportunity 
was provided; this point is explained in greater detail in sections 
VI.E.8 and VI.E.9 of this Preamble.
    EPA believes that the standards in Sec.  3.2000(b) of today's rule, 
as developed from the proposed ``Validity of Data'' criterion, together 
with other proposed criteria clarified as general performance 
standards, represent the minimum set of requirements for electronic 
document receiving systems necessary to ensure the legal dependability 
of the electronic documents such systems receive. For example, the 
requirement for a copy of record is necessary to ensure that there is 
an authoritative answer to the question of what information content a 
signatory was certifying to or attesting to. The related requirement 
that the system be able to provide timely access to copies of record 
and related data reflects a practical concern that the data be 
accessible in time and in a format to serve the purposes for which it 
is needed.
    Concerning the requirement that signature devices be uniquely 
assigned to, and held by individuals, EPA believes that an acceptable 
electronic document receiving system must be able to attribute a 
signature to a specific individual, to help assure that the signatory 
cannot repudiate responsibility for the signature. Non-repudiation is 
also strengthened by the signed electronic signature agreement, which 
establishes that the signatory was informed of his or her obligation to 
keep the signature device from compromise by ensuring that it is not 
made available to anyone else. Requiring the signature agreement, as 
well as the opportunity to review what they are signing, helps 
establish that where signatures appear on electronic documents, the 
signatories had the requisite intent to certify. That is, these 
requirements help ensure that the signatories knew what they were 
signing, knew what signing meant, and understood the legal implications 
of false certification. As for the requirement that document content 
cannot be altered without detection after signature, an acceptable 
electronic document receiving system must provide evidence sufficient 
to allow a court to attribute the intention to certify to the 
document's current content to the signatory, so that he or she cannot 
repudiate this content.
    Finally, today's Sec.  3.2000(b)(5)(vii) requirement that the 
system be able to establish the identity of the individual who is 
assigned a signature is based on proposed Sec.  3.2000(d). Proposed 
Sec.  3.2000(d) logically entails today's Sec.  3.2000(b)(5)(vii), 
because satisfying the

[[Page 59858]]

provisions of the former guarantees compliance with the latter. 
However, today's Sec.  3.2000(b)(5)(vii) limits the scope of the 
proposed Sec.  3.2000(d)(3) requirement that, in registering for their 
signature devices, registrants must execute their electronic signature 
agreements on paper with handwritten signatures. In today's Sec.  
3.2000(b)(5)(vii), this requirement is limited to a special class of 
``priority report'' submittals. (See section VI.E.12 of this Preamble.) 
In addition, today's Sec.  3.2000(b)(5)(vii) offers alternatives to 
this handwritten signature requirement, to allow electronic reporting 
solutions that are completely free of paper transactions. The 
alternative provisions, found in today's Sec.  3.2000(b)(5)(vii)(A)-
(B), are elaborations of the proposed Sec.  3.2000(d)(1) requirement 
for ``evidence [of identity] that can be verified by information 
sources that are independent of the registrant and the entity or 
entities'' for which the registrant will submit electronic documents. 
The elaborations are necessary to assure that individuals' identities 
can be established without being able to rely on their handwritten 
signatures--and, in the final rule, the requirements apply only to 
``priority report'' submittals, and only where the choice is made to 
not use paper in the execution of electronic signature agreements. 
Section VI.E.12 of this Preamble outlines all of today's Sec.  
3.2000(b)(5)(vii) provisions in much more detail. In any event, we have 
made these changes to the proposed Sec.  3.2000(d) approach to help 
address commenters' concerns with ``one size fits all'' provisions, as 
well as to allow states, tribes, and local government as much 
flexibility as possible as they implement their electronic reporting 
systems.
    In sum, the overall approach to the standards for electronic 
document receiving systems in today's rule reflects a balancing of the 
concerns raised by the public comments, especially those relating to 
the proposal's burden on states, tribes, local governments and 
regulated entities, against the need to ensure the legal dependability 
of electronic documents submitted under authorized programs. Finally, 
EPA notes that to date the Agency has had limited experience with the 
practical application of electronic signatures and electronic reporting 
generally. With the benefit of practical experience accepting 
electronic reports under this rule, EPA may determine that this rule 
needs to be revisited, to either add or eliminate certain safeguards. 
In addition, while EPA has sought to write this rule so that its 
provisions are technology-neutral, it remains possible that revisions 
will be required to reflect technological changes or changes in 
prevailing industry norms and practices. If these or other 
circumstances require it, EPA thus reserves the right to revisit the 
issues addressed in this rule.

C. How has EPA accommodated electronic submissions with follow-on paper 
certifications?

    Currently there are EPA and state programs that take electronic 
submissions where the requirements for a signed certification statement 
are met with a follow-on paper submission with handwritten signatures. 
A number of commenters suggested that such an approach be recognized 
and allowed to continue under the electronic reporting rule. EPA has no 
wish to proscribe such an approach, and does not judge whether or not 
follow-on paper signature/certification is to be preferred to the 
approach where the signature/certification is electronic. To make this 
clear in the final rule, we have added a clause to Sec.  3.10(b) that 
allows follow-on handwritten signatures to substitute for electronic 
signatures on submissions to EPA where ``EPA announces special 
provisions'' for this purpose. A corresponding clause in Sec.  
3.2000(a)(2) of today's rule makes a similar allowance for electronic 
reporting under authorized state, tribe, or local programs, again, 
where ``the program makes special provisions to accept a handwritten 
signature on a separate paper submission.''
    Among other things, these ``special provisions'' would allow 
follow-on paper signature submission only if it were reliably linked or 
cross-referenced with the associated electronic document. The linking 
or cross-referencing is necessary in part to ensure that we can always 
determine which signature submissions belong with which electronic 
documents. Paper signature submissions must also provide sufficient 
evidence that the signatory intended to certify to or attest to the 
content of the electronic document as this content is recorded in the 
copy of record for the submission. There are various approaches to 
cross-referencing or linking that would meet these needs, most of which 
involve the inclusion of extra data elements in the signature 
submission that reference the associated electronic document. Such data 
elements might include summary data from the electronic document, the 
date and time of the electronic submission, or even the calculated hash 
value of the electronic document. EPA may use these and other 
alternatives if a decision is made to provide for direct electronic 
reporting to EPA with follow-on paper signatures. For such submissions 
to authorized programs, we have added to Sec.  3.2000(a)(2) of today's 
rule the requirement that authorized program provisions for follow-on 
paper signature submissions ``ensure that the paper submission contains 
references to the electronic document sufficient for legal certainty 
that the signature was executed with the intention to certify to, 
attest to, or agree to the content of that electronic document.''

D. How has EPA changed proposed definitions of terms?

    The ``Definitions'' section of the final rule, Sec.  3.3, provides 
new definitions for ``copy of record,'' ``electronic signature 
agreement,'' and ``valid electronic signature,'' as well as the 
revisions to the definition for ``electronic signature device,'' to 
help articulate the final Sec.  3.2000(b) standards for electronic 
document receiving systems. These terms are explained in more detail in 
section VI, below. (See especially, sections VI.E.2., VI.E.10. and 
VI.E.6.) Similarly, in section VI.B.2 of this Preamble we note the role 
of the new definition for ``existing electronic document receiving 
system;'' and, in section VI.E.12 we discuss the new definitions for 
``agreement collection certification,'' ``disinterested individual,'' 
``information or objects of independent origin,'' ``local registration 
authority,'' ``priority reports,'' and ``subscriber agreement.'' 
Section 3.3 also reflects a number of clarifying and/or simplifying 
changes for definitions of terms, as follows.
    1. Definition of ``acknowledgment.'' This definition has been added 
in conjunction with Sec.  3.2000(b)(5)(vi) of today's rule, to make 
clear that in the context of this rule, acknowledgment means a 
confirmation of electronic document receipt.
    2. Definition of ``electronic document.'' This definition has been 
revised from the proposed version in several ways. First, the use of 
``communicate'' has been eliminated, thereby eliminating the need for a 
separate definition of that term. Second, the exclusion of magnetic and 
optical media and facsimile submissions has been eliminated. We believe 
it is clearer to exclude such submissions from the scope of CROMERR 
under Sec.  3.1, entitled ``Who does this part apply to?'' Today's rule 
now provides this exclusion in Sec. Sec.  3.1(b) and 3.1(c). Third, the 
definition has also been revised so that it explains what a 
``document'' is in an electronic medium. Instead of saying that an 
``electronic document means a

[[Page 59859]]

document. * * *,'' the final version says that ``electronic document 
means any information in digital form. * * *,'' where information is 
explained as potentially including ``data, text, sounds, codes, 
computer programs, software or databases.'' Fourth, this definition 
clarifies that in this context, ``data,'' is used in its normal sense 
as denoting a delimited set of data elements, each of which is a unit 
of meaning in a document and consists of a content or value together 
with an understanding of what the meaning and/or context of the content 
or value is. Finally, the definition stipulates that where an 
electronic document includes data, the understanding of what the data 
content or value means must either be explicitly included in the 
electronic document or be readily available through such sources as an 
applicable data element dictionary, or a form or template that 
specifies what each data element means when it is presented in the 
specific file format used for the electronic document's submission.
    A consequence of this approach is that the identity of an 
electronic document consisting wholly of data is independent of the 
format in which it is presented or submitted. That is to say, 
rearranging or reformatting the data elements in an electronic document 
does not change it into a different one, at least so long as the 
signatory's intention and understanding of what the data elements each 
mean is preserved in the process. This does not conflict with the 
ordinary understanding of the term ``document,'' since we speak quite 
often of ``reformatting a document,'' with the clear understanding that 
what results will be the same document in a new format. 
Correspondingly, under the definition of ``copy of record,'' a ``true 
and correct'' copy of an electronic document does not necessarily have 
to reflect the format in which the document was submitted, provided 
that the document consists wholly of data. This independence of 
document identity from format may not always hold where other kinds of 
information are included in the electronic document, e.g. text or 
images; in such cases a copy of record may have to include format or 
formatting information.
    3. Definition of ``electronic signature.'' This definition has been 
revised by substituting ``information in digital form'' for 
``electronic record,'' to avoid problems with defining ``electronic 
record.'' The definition has also been revised to make clear that the 
electronic signature for an electronic document need not always be 
``included'' within that document; in some cases it may just be 
``logically associated'' with it. This point is explained further in 
section VI.E.2 of this Preamble, in discussing the copy of record 
requirement.
    4. Definition of ``electronic signature device.'' The definition of 
``electronic signature device'' has been revised to clarify that where 
a device is used to create an individual's electronic signature, then 
the device must be unique to that individual, and he or she must be 
uniquely entitled to use it at the time that the signature is created. 
Correspondingly, the device is compromised if it is available for use 
by any other individual, that is, if some other individual is able to 
use the device to create signatures if he or she wishes. To the extent 
that Sec. Sec.  3.10(b) and 3.2000(b)(5)(i) of the final rule prohibit 
the acceptance of signatures created with compromised devices, via the 
definition of ``valid electronic signature,'' the element of compromise 
rules out the sharing of electronic signature devices or delegating 
their use to create individuals' electronic signatures. Additionally, 
the definition includes the element that an individual needs to be 
entitled to use the electronic signature device; that is, the 
individual needs to be the ``owner'' of the device. The nature of the 
device itself will determine the way in which an individual comes to 
own it. In the case of personal identification numbers or certificate-
based private/public key pairs, there is normally some process of 
formally assigning the device to the individual, often through a 
trusted third party. In other cases, for example password or personal 
information-based signature devices, the process may have the 
individuals invent and assign the devices to themselves `` the basis 
for their ownership of the devices being determined by the 
circumstances or context within which they do this.
    5. Definition of ``transmit.'' In the proposed rulemaking the term 
``submit'' was defined as the ``means to successfully and accurately 
convey an electronic document so that it is received by the intended 
recipient in a format that can be processed by the electronic document 
receiving system.'' However, the term ``submit'' is used more widely in 
the rule in ways that are not consistent with this definition. 
Accordingly, in the final rule the function of successful and accurate 
conveyance of an electronic document is now termed ``transmit.''
    6. Definition of ``valid electronic signature.'' Beyond its role in 
Sec.  3.2000(b), this definition has also been added to help clarify 
and simplify the signature requirements associated with electronic 
reporting, both directly to EPA, in Sec.  3.10, and under authorized 
programs, in Sec.  3.2000(a)(2). The definition specifies three main 
conditions for validity. The first refers to features of the signature 
that are intrinsic to the items of information of which it consists: 
The signature must consist of the kind of information that has been 
established as appropriate for the signing of the document in question, 
and the specific information content must pass the validation tests 
which the system uses to determine that the signature belongs uniquely 
to the identified signatory. The second condition refers to the status 
of the electronic signature device used to create the signature, and 
ensuring that the device was not compromised at the time it was used to 
create the signature. This ties validity to the element of compromise 
within the definition of ``electronic signature device.'' That is, at 
the time of signature, the device must not have been made available to 
someone other than the individual who is entitled to use it. The third 
condition refers to the signatory's status at the time of signature as 
someone who is authorized to sign the document in question by virtue of 
his or her legal status and/or relationship to the entity on whose 
behalf the signature is executed. In the context of environmental 
reporting, this condition would make invalid electronic signatures on 
company compliance reports created by individuals who do not work for 
or in any way represent the company. Generally, in the context of 
environmental reporting, individuals who sign submissions to 
environmental agencies are explicitly authorized to do so, by their 
management and/or by the agency to which they report. However, in some 
cases the authorization may be implicit in the signatory's legal status 
and relationship to the regulated entity. For example, an owner or 
operator of a company is generally authorized to sign notifications or 
letters to an environmental agency whether or not this is explicitly 
provided for by law or regulation.
    As ``valid electronic signature'' is used in Sec. Sec.  3.10 and 
3.2000(a)(2), the validity of an electronic signature is necessary for 
the signatory's electronic submission to satisfy a federal or 
authorized program reporting requirement. Additionally, as the term is 
used in Sec.  3.2000(b), it also refers to a performance requirement 
for an electronic document receiving system, namely that the system 
must not accept and must be able to detect submissions with signatures 
that are not valid. These requirements in terms of ``validity'' are

[[Page 59860]]

meant to provide a form of insurance for electronic signatures to 
protect against the risks of repudiation. Nonetheless, a signatory may 
be legally bound by a signature even where not all the requirements for 
its validity have been met, e.g., where the signature has been executed 
with a compromised electronic signature device. The signatory of an 
electronic submission cannot avoid responsibility for its contents by 
pointing to a technical flaw or other defect in the signature process.

V. Requirements for Direct Electronic Reporting to EPA

A. What are the requirements for electronic reporting to EPA?

    Under the final rule, the requirements for electronic reporting to 
EPA remain essentially unchanged from those in the proposal. Section 
3.10 provides, first, that electronic documents must be submitted to an 
appropriate EPA electronic document receiving system. Generally this 
will be EPA's Central Data Exchange (CDX), although EPA can also 
designate additional systems for the receipt of electronic documents 
and is doing so in a separate Federal Register notice. Second, where a 
paper document must bear a signature under existing regulations, an 
electronic document that substitutes for the paper document must be 
signed (by the person authorized to sign under the current applicable 
provision) with a valid electronic signature.
    Only electronic submissions that meet these two requirements will 
be recognized as satisfying a federal environmental reporting 
requirement, although failure to satisfy these requirements will not 
preclude EPA from bringing an enforcement action based on the 
submission or otherwise relying on the submission. A new compliance and 
enforcement section has been added to the final rule to clarify certain 
compliance and enforcement issues related to electronic reporting. 
Section 3.4 makes clear that EPA can seek and obtain any appropriate 
federal civil or criminal penalties or other remedies for failure to 
comply with an EPA reporting requirement if a person submits an 
electronic document to EPA under this rule that fails to comply with 
the provisions of Sec.  3.10. Similarly, Sec.  3.4 makes clear that EPA 
can seek and obtain any appropriate federal civil or criminal penalties 
or other remedies for failure to comply with a state, tribe, or local 
government reporting requirement if a person submits an electronic 
document to a state, tribe, or local government under an authorized 
program and fails to comply with the applicable provisions for 
electronic reporting. Section 3.4 also contains provisions originally 
published under Sec.  3.10(d) and (e) of the proposal, stipulating that 
the electronic signature will make the person who signs the document 
responsible, bound, or obligated to the same extent as he or she would 
be signing the corresponding paper document by hand.
    The Sec.  3.10 requirement that there be an electronic signature 
applies only where a paper document would have to bear a signature were 
it to be submitted, either because this is required by a statute or 
regulation, or because a signature is required to complete the paper 
form. The rule does not impose any new or additional signature 
requirements for documents that are submitted in electronic form. In 
addition, as noted in section IV.C of this Preamble, Sec.  3.10(b) of 
today's rule also allows EPA to make special provisions, in specific 
cases, for accepting handwritten signatures in follow-on paper 
submissions in lieu of the required electronic signatures. In such 
cases, it is critical that the special provisions ensure that the 
electronic document cannot be altered without detection and is reliably 
linked to the handwritten signature.
    As in the proposal, this final rule does not specify any required 
hardware or software. Accordingly, the rule text does not include any 
detail about CDX per se or about what will be required of regulated 
entities who wish to use it. Nonetheless, as stated in the proposal, 
our goals include the sharing of detail on how CDX implements direct 
electronic reporting to EPA. Section V.C.4 of this Preamble explains 
how CDX has changed since we described it in the proposal, especially 
in relation to the many comments we received on CDX-related issues.

B. What is the status of existing electronic reporting to EPA?

    In a notice published concurrently with today's rule, EPA clarifies 
the status of electronic reporting directly to EPA systems that exist 
as of the rule's publication date. In accordance with 40 CFR 3.10, EPA 
is designating for the receipt of electronic submissions, all EPA 
electronic document receiving systems currently existing and receiving 
electronic reports as of the date of this notice. This designation is 
valid for a period of up to two years from the date of publication of 
this notice. During this two-year period, entities that report directly 
to EPA may continue to satisfy EPA reporting requirements by reporting 
to the same systems as they did prior to CROMERR's publication unless 
EPA publishes a notice that announces changes to, or migration from, 
that system. Any existing systems continuing to receive electronic 
reports at the expiration of this two-year period must receive 
redesignation by the Administrator under Sec.  3.10. Notice of such 
redesignation will be published in the Federal Register.
    EPA's goal is that all its systems for receiving electronic reports 
be consistent with the CROMERR standards for electronic document 
receiving systems, set forth in Sec.  3.2000(b) of today's rule. EPA 
generally hopes to achieve this consistency within a two-year 
transition period for existing EPA systems; however, EPA is not bound 
by the Sec.  3.2000(b) standards of today's rule or the two-year 
period. This two-year period is similar to the two-year transition 
period provided under Sec.  3.1000(a)(3) for systems operated under 
EPA-authorized programs. In a number of cases, EPA may work toward this 
goal by migrating existing electronic reporting to CDX or to other, new 
CROMERR-consistent systems. As we change or migrate existing electronic 
reporting programs to achieve consistency with the CROMERR standards, 
we intend to provide sufficient advance notice to reporting entities so 
that any new requirements can be accommodated without causing 
significant disruption to their electronic reporting activities.

C. What is EPA's Central Data Exchange?

    1. Overview of general goals. The proposal described EPA's 
``Central Data Exchange'' as a system to be developed and maintained by 
EPA's Office of Environmental Information (OEI) that would serve as 
EPA's gateway or ``portal'' for receiving documents electronically from 
our reporting community. The goal of CDX was to augment, and, where 
appropriate, streamline and consolidate EPA's environmental reporting 
functions by offering our reporting community faster, easier, and more 
secure submission options through a single venue for electronic 
submission of environmental data. As a cornerstone of EPA's efforts to 
advance electronic government, CDX would support the electronic 
submission needs of thousands of regulated entities submitting data to 
EPA for certain air, water, waste, and toxic substances programs. 
Ultimately, EPA planned to offer, wherever practicable, all regulated 
entities that report directly to EPA, an option to file their specific 
environmental documents

[[Page 59861]]

electronically through CDX. Regulated entities that submit reports 
under an authorized program would also be able to file their documents 
through CDX in cases where the state, tribe or local government that 
administered the program chose to use CDX as a gateway for electronic 
data submissions from its reporting community.
    The reporting community using CDX would be able to access web 
``reporting'' forms with built-in data quality checks, and/or submit 
standard file formats through common, user-friendly interfaces that 
allowed them to electronically submit data across vastly different 
environmental programs. Both the reporting community and EPA would 
benefit by gaining access to environmental reports more quickly and 
with fewer errors, and by avoiding the inefficiencies of having to 
keystroke data from paper reports. CDX was also being developed to 
support a newly emerging Environmental Information Exchange Network 
(EIEN) that would facilitate the electronic exchange of environmental 
data between EPA and state, tribe, and local environmental agencies. 
However, in keeping with the scope of the proposed rule the description 
of CDX features and functions in this section apply only to electronic 
submissions to CDX from regulated entities; the description doesn't 
apply to EIEN exchanges with CDX in which states, tribes, or local 
governments participate as a part of their authorized programs or as a 
part of administrative arrangements with EPA to share data.
    The Concept of Uniformity. The proposal also characterized CDX as 
providing an environment that would promote a uniformity of 
technologies and processes. By adopting CDX to support the electronic 
reporting needs across various EPA programs, EPA hoped to avoid the 
proliferation of program-specific electronic reporting approaches that 
could lead to duplicative investments in electronic document receiving 
systems and possibly conflicting requirements for submitters.
    The CDX Functions and Building Blocks. As described in the proposed 
rule, CDX was being designed with the goal of fully satisfying the 
criteria that the proposal specified for state, tribe, and local 
electronic document receiving systems; similarly, EPA would ensure that 
other systems the Administrator designated to receive electronic 
submissions satisfied the criteria as well. The proposal discussed how 
CDX would implement CROMERR-compliant electronic reporting by 
describing the primary CDX functions and the system building blocks 
that would support these functions. The functions described in the 
proposal included: (1) Access management, (2) data interchange, (3) 
signature/certification management, (4) submitter and data 
authentication, (5) transaction logging, (6) copy of record provisions 
and acknowledgment, (7) archiving, (8) error checking, (9) translation 
and forwarding, and (10) outreach. The proposal then described five 
building blocks that would support CDX functions, which were: (1) 
Digital signatures based on PKI, where CDX would rely predominately on 
a third party vendor under the General Services Administration (GSA) 
Access Certificates for Electronic Services (ACES), (2) a process for 
registering users and managing their access to the CDX, (3) a client 
server-architecture, (4) EDI standards, as the primary format for 
exchanging environmental data, and (5) a consistent user interface for 
making electronic submissions.
    2. Comments on the proposal. EPA received more than 100 comments on 
the CDX concept as described in the proposal. A number of these 
comments were related to one of four main subject areas, as follows.
    Comments on Uniformity of Approach. Several comments expressed 
concern about the proposed characterization of CDX as promoting 
``uniformity of process and technology''. The phrase was used to 
highlight the benefits of CDX, which included EPA's plans to avoid the 
costly proliferation of redundant systems. However, comments pointed 
out that this ``uniformity'' implied an inflexible and overly 
prescriptive set of CDX technical and security requirements, which 
would discourage CDX use. Such comments were similar to those discussed 
in section IV.B.2 of this Preamble, raising concerns about the 
prescriptiveness and ``one size fits all'' approach of the proposed 
criteria for electronic document receiving systems.
    EPA understands that ``uniformity of process and technology'' could 
imply inflexibility, and this is not generally how we intended to 
develop CDX. In fact, CDX is currently using a wide range of 
technologies and processes to address CDX's functions that are tailored 
to individual EPA program submission requirements, including the 
technical capabilities of the reporting community for the particular 
program. EPA recognizes that, for example, permitting, compliance 
monitoring, and the conduct of studies involve fundamentally different 
business processes, and that the associated submission of electronic 
documents may have to be handled differently in each case. In some 
instances CDX may support a more interactive ``workflow'' environment 
for submitting data; in others, CDX may accept batch transmissions of 
user-formatted files. It is also true that the technical capabilities 
of a particular reporting community vary considerably, so CDX will 
offer more than one electronic submission option in many cases. CDX 
currently provides support for web-forms, file, and record-level 
submissions in various formats including flat file and XML and EPA 
plans to continue this flexible approach.
    Comments on registration process. Comments from regulated entities 
raised concerns about the costs and time required to register 
individuals in each company, and EPA's failure to address the 
increasingly common cases where the preparer of an environmental report 
and the certifying official are different individuals.
    Because electronic submission is being offered as an option to the 
reporting community, EPA recognizes the need to design CDX registration 
to be as user-friendly as practicable, in part by taking account of the 
flow of work, or ``workflow'' involved in meeting a particular 
environmental reporting requirement. For example, since proposal, EPA 
has developed approaches to register both preparers and certifying 
officials for at least two reporting programs. Changes to the CDX 
registration process are discussed in more detail in section V.C.4.
    Comments on digital signatures based on PKI. Comments pointed out 
that reliance on PKI for all cases of electronic signature may violate 
the GPEA directive to vary electronic signature approaches with the 
circumstances of their use. Several comments underlined this concern by 
pointing to PKI's costs and burdens. The comments objected that 
registering through CDX and acquiring digital signature certificates 
would be overly complicated, and would require that registrants provide 
private or personal information. Some comment also expressed concern 
about the incompatibility of a PKI-based approach with workflow, given 
that environmental reports were frequently prepared by staff and then 
signed by the facility owner, with staff turnover being frequent. 
Another concern was the implications of CDX PKI software for company 
system security, for example, given the need to download CDX software 
through the company firewall.
    EPA agrees that it should generally minimize the complexity and 
cost of electronic signatures or this will deter potential users of CDX 
from submitting

[[Page 59862]]

electronic documents. In implementing CDX, EPA has revised the initial 
plan for electronic signatures to include non-PKI electronic 
signatures. Section V.C.4 discusses how we are changing the ``digital 
signature based on PKI building block.''
    Comments on EDI Standards. Comments expressed both encouragement 
and concern over CDX's prospective implementation of standards-based 
exchange formats for data submissions. An exchange format is a 
predefined file structure, including data elements and higher level 
syntax that describes how the data extracted from a system must be 
arranged in a file for transmission to another system. A standards-
based format adheres to certain widely-accepted industry, national, or 
international file structure definitions. Several comments expressed 
concern about the costs of configuring their systems to generate a CDX-
specified standard format; others expressed concerns about the costs of 
potential changes to the format once it is implemented on their 
systems. By contrast, other comments strongly supported requiring 
standards-based formats--even recommending that we require such formats 
by rule for EPA and EPA-authorized state, tribe, and local electronic 
document receiving systems.
    CDX's approach to standards-based formats has changed considerably 
since the proposal, in large part because of the emergence of Internet-
based approaches, most notably Extensible Mark-up Language (XML). These 
changes are discussed in more detail in section V.C.4. EPA believes 
that the use of standard formats can be encouraged without requiring 
this by rule. Additional comments on CDX and EPA's responses can be 
found in the rulemaking docket, in the Response to Comments document.
    3. The aspects of CDX that have not changed since proposal.
    General Goals. EPA's continues its efforts to establish CDX as the 
gateway or ``portal'' for receiving documents electronically from the 
Agency's reporting community. In so doing, EPA's goal--to augment, and 
where appropriate, to streamline and consolidate EPA's environmental 
reporting functions through CDX--remains unchanged. The functions that 
comprise CDX operations continue to remain the same though the range of 
technologies and processes used to support these functions has 
considerably broadened. CDX continues to implement electronic reporting 
capabilities for EPA's many environmental programs, while advancing the 
efforts of EIEN in coordination with state, territorial, tribes, and 
other partners.
    General Approach to Electronic Reporting Implementation. In 
general, current instructions for client-side access of CDX suggest 
Internet access and a system that uses both Microsoft Windows and 
Microsoft Internet Explorer (IE). EPA acknowledges that the Government 
Paperwork Elimination Act (GPEA) directs OMB to develop procedures for 
agencies to follow in using and accepting electronic documents and 
signatures and these procedures ``may not inappropriately favor one 
industry or technology.'' Consistent with this GPEA directive, EPA is 
committed to considering ways to allow other vendors' technologies to 
access CDX. Accordingly, over the six months following the publication 
of today's rule, EPA intends to assess the full range of issues that 
affect CDX's ability to support multiple platforms and browsers. These 
issues include the technical requirements for the electronic signature 
options, form entry options, data upload options, network interface 
options, current capabilities of the CDX hardware/software platform, 
and potential impacts of new client-side platforms on the CDX life 
cycle management, technical support requirements, and help desk 
training and support. Based on this assessment, EPA intends to 
determine the target universe of client-side platforms and browsers 
that CDX can feasibly accommodate, and will identify the actions and 
timeline necessary to build out CDX support for this target universe.
    As described in the proposal, CDX users will need to:
     Register with CDX, during which time they may need to 
supply information used to identify themselves, their company, and the 
EPA documents they wish to submit electronically;
     Verify and/or correct registration information; and
     Access their CDX web account through a secure website, and 
agree to the terms and conditions of using the site, which include 
safeguarding their self-generated password, before using web forms or 
uploading files to submit electronic documents or data to EPA.

These are the minimum steps for gaining access to CDX at this time. 
Additional steps are involved in acquiring an electronic signature 
device, although these steps have changed somewhat since the proposal 
and are discussed in section V.C.4. CDX also offers at least two 
general methods for reporting electronically for many programs it 
supports, either through file submission or through a ``smart web 
form''. However, the types of formats and approaches for submitting 
data through CDX have broadened, and these too are discussed in section 
V.C.4.
    4. The major changes that EPA has made to CDX since proposal. Over 
the last two years, CDX has evolved from a prototype system to a fully 
operational electronic document receiving system. CDX supports tens of 
thousands of registered users providing data to dozens of environmental 
reporting programs across the major EPA media offices. CDX registered 
users include representatives from state, tribe, and local agencies, 
industries, laboratories, and other federal agencies. While CDX 
continues to provide a secure, single point of registration, access, 
and exchange between reporting entities and EPA programs, the building 
blocks supporting the CDX functions have changed substantially. These 
changes reflect EPA's experience operating CDX over the past two years, 
evolving trends in Internet technologies, and comments received on the 
proposed rule from potential CDX users.
    Digital signatures based on PKI. The proposal described the CDX 
approach to electronic signatures in terms of digital signatures and 
PKI. Since proposal, EPA has come to appreciate the complexity and 
costs of implementing PKI, and to recognize that non-PKI electronic 
signatures, as described in section IV.B.2 of the preamble today's 
rule, may be acceptable in many cases. Thus, for electronic reports 
currently submitted to CDX, only in one case is PKI used for electronic 
signature. The other cases involve PIN-based electronic signatures or 
other non-PKI electronic signature approaches. As an example of the 
latter, this year we anticipate implementing electronic signatures for 
an EPA reporting requirement by having signatories use a password that 
is self-generated during CDX registration in combination with certain 
items of information that are unlikely to be available to anyone except 
the signatory. This is a ``knowledge-based'' approach, which is being 
used extensively by commercial software vendors supporting the United 
States Internal Revenue Service (IRS) for electronic tax filings or 
``e-filings', and is being adopted by other agencies. EPA expects that 
these non-PKI-based approaches to signature will continue to dominate 
CDX implementations of electronic reporting. We currently intend to use 
PKI where such needs as security or assuring very robust non-
repudiation of signature make this the most appropriate approach.

[[Page 59863]]

    In addition, EPA's approach to PKI itself--described in the 
proposal as relying on ACES--is also undergoing change. Changes with 
respect to the role and method of identity proofing for those persons 
who apply for PKI certificates is being further evaluated. As proposed, 
the identity proofing was to be conducted by the third party ACES 
vendor; currently, CDX identity proofing is conducted for the most part 
by EPA's own contractor staff, who are able to issue digital 
certificates to members of the reporting community with less cost and 
in less time than the ACES vendor. EPA has also begun to explore 
alternatives to ACES for PKI certificates, partly because ACES-provided 
certificates do not support message encryption, which EPA may need for 
certain environmental reporting applications. In addition, EPA is 
considering its use of ACES in the light of recent federal advances in 
establishing interoperability across federal PKI domains, which may 
allow EPA to eventually leverage PKI's of other federal agencies or 
institute an in-house PKI.
    CDX Registration. Since the proposed rule, CDX has broadened it 
approach to registration to better accommodate the workflow involved in 
specific environmental reporting programs. While CDX still requires 
registration, there are three distinct areas where the registration 
process has changed since proposal. First, the proposal described CDX 
registration as the first step toward the issuance of a PKI-based 
digital signature, and it was implied that all persons opting to use 
CDX would need a digital signature. As noted above, this is no longer 
the case. Second, in the proposal, CDX registration began when a person 
received an EPA invitation letter that contained a temporary code and 
instructions on how to access the CDX registration website. CDX has 
adopted additional approaches to initiating registration for certain 
EPA programs, for example, embedding a link to CDX registration in 
reporting software that is distributed to the program's reporting 
community, or providing a public website where prospective CDX users 
can submit initial registration data EPA. While CDX continues to 
register persons by invitation letter for reporting under certain 
environmental programs, registration options will continue to broaden 
as the number of environmental programs supported by CDX expands.
    Finally, in the proposal, CDX registration was completed when the 
registrant printed out a ``signature holder'' agreement from the CDX 
registration website, signed this agreement and mailed it to EPA's CDX. 
CDX will continue this approach for reports where electronic signatures 
are required, although EPA is exploring the use of an entirely 
paperless signature agreement process for at least some of these cases. 
CDX registration to submit reports that do not include electronic 
signatures will not involve a ``signature holder'' agreement.
    EDI Standards. The proposal described EPA's plans to use EDI as the 
basis of standards-based formats for exchanging data between reporting 
entities and CDX. Since proposal, CDX development has reflected a 
significant evolution in formatting standards to accommodate the 
Internet--away from EDI and toward the use of XML. XML consists of a 
set of predefined tags and message structures that, like EDI, allows 
machine-to-machine exchange of data in a mutually agreed upon format, 
enabling exchange of data across different systems. However, unlike 
EDI, XML is tailored to Internet-based communications and security 
protocols. Additionally, an XML formatted file in combination with a 
style sheet can be displayed in a Web browser. Such features would 
allow CDX to use the same standard format both for exchanging data 
files and for designing web forms. The structure of XML also addresses 
some of the challenges in archiving data received, because the XML tags 
that accompany the data in an XML file can be used to interpret the 
data's context without the aid of additional software. This could 
facilitate the recovery of data from archived files, and reduces the 
need to maintain the versions of the software originally used to 
generate the files.
    CDX and specific EPA programs may address the question of which (if 
any) standards-based format to use for a particular report on a case-
by-case basis, and EPA intends to develop appropriate technical 
instructions for CDX submitters as program-specific reporting formats 
are adopted. These instructions normally will be distributed to the 
affected reporting communities via links on the CDX website and/or 
through program and CDX outreach efforts. EPA is working with 
authorized state, tribe, and local programs to develop standards-based 
reporting formats to meet their shared needs. In many instances, CDX 
contemplates a long transition period between file formats currently 
used to exchange data with regulated entities and any new, standards-
based formats. During this transition, CDX may offer submitters several 
electronic submission options; these may include an existing data 
format familiar to submitters, one or more new standards-based formats, 
and some other approach such as a smart-form hosted on a secure 
website.
    Client-side architecture and transaction environment. The proposal 
described a downloaded ``client'' that would generally supplement the 
browser to support the signature and security for CDX; such ``client 
side'' software is no longer needed for all cases of electronic 
reporting to CDX. However, in some cases CDX now uses various 
technologies to transparently insert routines into browsers during a 
user session to support special functions--for example to support the 
creation of a PKI-based electronic signature with an ACES business 
class certificate.

D. How will EPA provide notice of changes to CDX?

    As noted in the proposal, the fully-implemented CDX will be subject 
to change over time, to take advantage of opportunities offered by 
evolving technologies, as well as to improve the system. EPA's decision 
to avoid codifying technology-specific or detailed procedural 
provisions for electronic reporting is meant, in part, to accommodate 
changes to CDX without requiring that we amend our regulations. 
Nonetheless, EPA recognizes that such changes can affect regulated 
entities that participate in electronic reporting; therefore, the final 
rule provides for advance notice when EPA intends to make changes to 
CDX. As discussed in the proposal, we distinguish four categories of 
changes:
     ``Significant'' changes that are likely to affect the 
kinds of hardware, software or services involved in transmitting 
electronic reports (Sec.  3.20(a)(1));
     ``Other'' changes that will affect the process or the 
timing of transmitting electronic reports to CDX, but without affecting 
the kinds of hardware, software or services involved in making the 
transmissions (Sec.  3.20(a)(2));
     ``Emergency'' changes necessary to protect the security or 
operational integrity of CDX (Sec.  3.20(b)).
     ``De minimis or transparent'' changes that will have 
minimal or no impact on the process or the timing of transmitting 
electronic reports to CDX.

``Significant'' changes include changes to the types of file formats 
CDX will accept--for example a change from extended markup language 
(XML) formats to some non-XML format--as well as changes to the 
technologies that may be used for file transfer to CDX or for creating 
electronic signatures on transmitted reports. ``Significant'' changes 
will not generally include optional upgrades to software, the

provision of additional formatting (or other technical) options, or 
changes to CDX that simply reflect changes to the underlying regulatory 
reporting requirements. ``Other'' changes include an increase in--or 
re-ordering of--the steps involved in transmitting electronic reports, 
changes to the registration or credential (e.g., PIN, password, PKI 
certificate) provisioning process that could affect users ability to 
access CDX, and changes to reporting formats that involve the 
reconfiguration of software. ``Emergency'' changes include such things 
as an upgrade to the system firewall protection. Finally, ``de minimis 
or transparent'' changes include the myriad small or ``back end'' fixes 
and improvements that EPA makes to CDX each week that have minimal or 
no impact on the transmission process. Such changes may range from 
fixing a typo on a data entry screen to re-engineering the system's 
archiving routines.
    To address ``significant'' changes, Sec.  3.20(a)(1) of the final 
rule provides that EPA will give public notice in the Federal Register 
of such changes and will seek comment. EPA proposed to provide this 
notice at least a year in advance of contemplated implementation, but 
based on experience developing and operating a CDX prototype, EPA no 
longer believes that a single time-frame is appropriate in all 
situations. For example, ``significant'' changes that could affect the 
transmission of an annual report may respond to needs or events that 
arise less than a year in advance of the report's due date. On the 
other hand, some ``significant'' changes may require more than a year 
for reporting entities to accommodate. Accordingly, the final rule 
provides that these Federal Register notices will propose and seek 
public comment on an implementation schedule for a ``significant'' 
change, along with describing and inviting comment on the change 
itself. To address ``other'' changes to CDX, Sec.  3.20(a)(2) of the 
final rule provides that EPA will give notice at least 60 days in 
advance of implementation. The notice in this case will typically be to 
CDX users, and the method of notice may be electronic, perhaps using 
the facilities of CDX itself. For ``emergency'' and ``de minimis or 
transparent'' changes, EPA will make decisions on whether, when, and 
how to provide public notice on a case-by-case basis.

VI. Requirements for Electronic Reporting Under EPA-Authorized Programs

A. What is the general regulatory approach?

    As explained in Part V of this preamble, the requirements in Sec.  
3.10 of today's rule apply to reporting entities that submit electronic 
reports directly to EPA. By contrast, today's rule contains no 
requirements that apply directly to entities who submit electronic 
reports to state, tribe, or local government agencies. However, Subpart 
D of today's rule does contain requirements that apply to state, tribe, 
or local government agencies that operate EPA-authorized programs. 
Subpart D of today's rule requires that such agencies that receive, or 
wish to begin receiving, electronic reports under an authorized program
