21st Century Integrated Digital Experience Act - Report
to Congress on Modernizing Agency Websites and
Digital Services

As required by section 3(b)(2) of Public Law 115-336,1 the 21st Century Integrated Digital
Experience Act (21C IDEA), this report includes a list of key websites and digital services
operated by EPA that have been prioritized and targeted for modernization.

Background

The 21st Century IDEA requires each federal executive branch agency to provide a prioritized list
of the agency's "most-viewed or utilized by the public or are otherwise important" public websites
and digital services in compliance with section 3(a) of the law, and to provide an estimation of the
cost and schedule to modernize those sites and services.

Overview of EPA's Web Presence

The EPA's primary public website is www.epa.gov. It is our most important channel for sharing
environmental information with the American public. In FY23 www.epa.gov received
approximately 10 million hits per month (down from 17 million in 2022; 20.9 million in 2021; 20
million in 2020 and 13 million in 2019) and 3.5 million unique visitors per month (down from 4.6
million in 2022; 5.8 million in 2021; 5 million in 2020 and up from 3 million in 2019).
www.epa.gov is managed by EPA's Office of the Administrator (OA) / Office of Public Affairs
(OPA) / Office of Web Communications (OWC) and the Office of Mission Support -Information
Technology/Information Management (OMS-IT/IM) / Office of Information Management (OIM) /
Information Discovery Division (IDD). Rigorous governance and management controls have
been implemented to optimize adherence to 21C IDEA and other federal web management
requirements (see Table 3: Summary of 21st Century IDEA Requirements).

In addition to www.epa.gov, EPA owns 12 other domains and hundreds of subdomains which
serve more specialized needs for more specific audiences. These domains and subdomains are
managed by the individual program offices within EPA. OWC and OMS lead a central web
governance council which provides agency-wide policies, procedures, standards, and guidance
to help the program offices implement web management best practices. This report shows that
EPA's primary website, www.epa.gov, complies with all requirements of the 21C IDEA and it also
describes the steps that EPA is taking to improve compliance on all domains.

Modernization Priorities

Progress Since Last Report

In Fiscal Year (FY) 2023, EPA undertook several major initiatives to bring its web presence into
compliance with the 21C IDEA.

EPA Web Inventory

In 2020 the Agency conducted its first comprehensive inventory of all web properties by
compiling data from various sources including GSA's Digital Dashboard, Google Analytics, EPA's
Hypertext Transfer Protocol Secure (HTTPS) Tracking Report, and EPA's Registry of
Environmental Applications and Databases. In 2020, EPA reported over 450 internal and
external website URL's (subdomains). In 2021, the inventory identified over 500 internal and
external website URL's (subdomains) belonging to EPA. For last year's report, the inventory
identified over 600 internal and external website URL's (subdomains) belonging to EPA. For this
year's report, the inventory identified over 800 internal and external website URL's (subdomains)
belonging to EPA. EPA continues making significant progress identifying points of contact for
each website.

WebCMS Upgrade

EPA is nearly complete with work to upgrade its Web Content Management System (WebCMS)
to Drupal 10. EPA has incorporated a new administrative theme, an update to Hypertext
Preprocessor (PHP) version 8, and a new What You See Is What You Get (WYSIWYG) editor for
making content edits easier for its users. EPA also completed a major effort to achieve hosting
redundancy, by setting up multi-Amazon Web Services (AWS) Region failover and back. Such
work allows www.epa.gov to continue running, even if AWS has regional issues. The application
was updated six times with over 150 feature enhancements, over 75 bugfixes and security
updates, and over ten accessibility improvements. In 2023, EPA's flagship website,
www.epa.gov, which is managed in the WebCMS, ranked in the top 1% of the top 1,000,000
website home pages with zero accessibility errors in the world. EPA continues to promote the
use of the United States Web Design System (USWDS) 3.6 implementation by www.epa.gov to
additional EPA domains and subdomains so they fully meet all of the requirements of the Office
of Management and Budget (OMB) Memo M-23-22. Delivering a Digital-First Public Experience.

Intranet Modernization

In FY19, EPA established an Intranet Council to oversee the implementation of an enterprise
intranet governance framework. In FY20, EPA embarked on an Intranet Modernization effort to
improve communications through consistent local and national messaging; improve collaboration
by leveraging 0365; increase productivity by providing easy, seamless access to information,
tools, and services; and improve efficiency by implementing industry-leading web management
best practices. In FY21, EPA conducted an Enterprise Content Management System (Intranet
CMS) pilot based on the newly released United States Web Design System 2.0. In FY22, EPA
successfully launched its new Intranet CMS which fully complies with the 21C IDEA by using an
open-source Drupal-based platform to implement internal web management directives including
procedures, standards, and guidance. The new design also uses the USWDS 2.0 code library,
tools, guidance, user research, and modern best practices to make it easier to manage,
organize, and present EPA's internal enterprise content in a way that meets evolving information
needs. In FY23, EPA began the work to migrate their on-premise Intranet CMS environment to
the cloud. In FY24, EPA migrated the Intranet CMS to the Amazon Web Services (AWS) Cloud

4


-------
and will begin the upgrade to Drupal 10, incorporating a new administrative theme, an update to
Hypertext Preprocessor (PHP) version 8 and USWDS 3.3.

Web Compliance Monitoring

EPA will expand its Web Analytics capabilities to more subdomains in FY24 to provide more
granular data to monitor and track improvements in compliance with 21C IDEA. Additionally, to
track EPA's subdomains (both internal and external), EPA modified its procedures for requesting
new subdomains to stop the uncontrolled proliferation of new websites and to require that new
subdomains are created in compliance with 21C IDEA and other Federal Web management
requirements.

In FY22 EPA served as the first Agency to participate in a pilot with GSA to report out on the
status of 21C IDEA compliance at the subdomain level on diqitaldashboard.gov (DD). The
subdomain pilot went live on April 2022 which included 20 EPA subdomains on GSA's Digital
Dashboard. The subdomain DD pilot provided great insight on the status of EPA's website
compliance, and the ability to prioritize improvements needed.

All of EPA's public web domains and subdomains on GSA's Digital Dashboard and IT Dashboard
have achieved full compliance with the Digital Analytics Program (DAP) using EPA Google Tag
Manager. IDD will continue to monitor, track, and assist programs in improving compliance.

In FY23, IDD focused on improving HTTPS requirements for both its public and intranet websites
in partnership with the Office of Information Security and Privacy (OISP). EPA will be applying
the HTTPS Strict Transport Security (HSTS) protocol on the epa.gov root domain by the end of
December 2023.This means that every subdomain on epa.gov will enforce HTTPS and will not
be accessible through an insecure connection (i.e., via HTTP). That includes public sites like
www.epa.gov, extranet sites like cdx.epa.gov, and intranet sites like work.epa.gov. Also, in FY23,
IDD partnered with the Section 508 Team to reduce the number of missing alt tags on public
pages from 12% to 3%. IDD is currently working on the deployment of the Web Tools Intranet
Site Scanner which is an open-source tool that run accessibility tests on intranet pages.

Lastly, EPA will assess the utility of the IT Dashboard to replace any existing quality or
compliance services managed internally to see if cost savings can be achieved through
leveraging the results of Dashboard services as an alternative.

Data Collection Methodology

Back in 2019 data for this report was collected by surveying all EPA domain owners across the
Agency. Each domain point of contact was asked to provide their best estimate of the degree to
which the web pages on their domain complied with the 21C IDEA and other federal web
management requirements.

Since 2020 EPA started collecting data using web analytics tools, digitaldashboard.gov, and EPA's
Web Governance Framework and on-site reviews. EPA used digitaldashboard.gov to collect
objective data for 2 out of the 8 requirements from the 21C IDEA. They include accessibility and
mobile-ready. For this year's report, EPA used itdashboard.gov to collect objective data for 4 out of
the 8 requirements from the 21C IDEA. They include accessibility, secure connection, data driven
design and mobile-ready, ltdashboard.gov is a federal website managed by GSA that provides
information about Federal Websites' compliance with OMB directives and conformance to best
practices and industry standards. The IT Dashboard Federal Web Metrics includes data for the 26
IT Portfolio Management (ITPM) reporting agencies (per OMB Circular A-11 section 55). The data
is collected from automated scans of public-facing websites for these 26 IT Portfolio Management
reporting agencies. The list of public-facing websites for the 26 IT Portfolio Management agencies

5


-------
are provided by GSA's Site Scanning program. EPA's Web Governance Framework was used for
eliminating redundancy and on-site reviews for identifying consistency, search and customization.
A summary of results can be found in Table 3: Summary of the 21st Century IDEA Requirements -
EPA Domains; Table 4: Summary of the 21st Century IDEA Requirements - EPA's Most Visited
Subdomains. EPA is using these tools to measure compliance with the 21C IDEA requirements on
EPA's subdomains as well.

Implementing Requirements

The section below explains how EPA complies with each of the 21C IDEA requirements.

Section 3(a)(1) Ensure Accessibility for Individuals with Disabilities

EPA is committed to the principle that people with disabilities should have comparable access to
accessible information and communication technology. EPA has tools and staff dedicated to
ensuring implementation of this requirement on www.epa.gov however additional tools and
resources are required to accurately measure and track remediation on all EPA domains and
subdomains. The programs and resources that support this requirement include:

•	Section 508 Program - EPA's Section 508 Program provides agencywide
coordination and oversight to ensure compliance with federal accessibility
requirements.

•	EPA Section 508 Compliance Assessment and Remediation Plan - EPA's
Section 508 Compliance Assessment and Remediation Plan assesses and enhances
the accessibility of EPA's existing Information and Communications Technology,
while also developing a baseline from which to measure improvements and providing
a framework for focusing EPA's Section 508 efforts moving forward.

•	Drupal WebCMS - EPA's agencywide, content management system has a
Section508 compliance certification requirement before publishing to www.epa.gov.

•	Web Analytics Program - EPA's Web Analytics program supports the Agency's 508
goals by providing tools to help identify and recommend solutions regarding the
conformance of www.epa.gov webpages.

The results for accessibility were collected from the IT Dashboard Report dated October 31,
2023, and compliance was determined by the total number of accessibility issues. Websites
without any accessibility issues were considered compliant. Websites with accessibility issues
were considered non-compliant. IT Dashboard accessibility module scans for certain common
accessibility issues such as color contrast issues, HTML attribute issues and missing image
description.

Section 3(a)(2) Ensure a Consistent Look and Feel Across Websites

All of EPA's public content pages or web applications are required to use the One EPA Web look
and feel which is based on the United States Web Design System: USWDS. The "look and feel"
enables each web page to be clearly identified on EPA's public access website as belonging to
EPA and ensures that each page has required navigational and other design elements. The EPA
has tools and staff dedicated to ensuring implementation of this requirement on www.epa.gov.

The results for consistency were determined by an on-site review. All domains were manually
inspected. Numerous pages from each domain were spot checked, determining a consistent look
and feel. Domains with a consistent header and footer throughout all pages were considered
compliant. Domains without a consistent header and footer were considered non-compliant.

Initiatives that support this requirement include:

9


-------
•	EPA Content Review and Approval Process - EPA's Office of Web Communications
reviews all new or redesigned web content before it is published. This review helps
ensure a consistent look and feel across EPA's websites.

•	Procedure: Complying with EPA.gov "Look and Feel" - This procedure defines the
requirement to use a standard layout for EPA's public access webpages and Web
applications so that they are published with a consistent "Look and Feel." The steps for
requesting a waiver or exemption from using required specifications of the EPA "Look
and Feel" are also included in this procedure. The following types of pages are exempt
from the "Look and Feel" specifications and require registration, but do not need a waiver:
Partnership Sites, Kid Pages, Tracking Statistics, and Extranet Sites.

•	Web Standards: Look and Feel Template - This standard template provides the look
and feel for the top and bottom of each EPA webpage. The WebCMS produces this look
and feel automatically. All applications should use the standalone template.

•	Standalone Template for Applications - EPA maintains a Standalone One EPA Web

Template with the EPA Look and Feel which can be used for all data and content not in
the Drupal WebCMS. Content owners can wrap this template around application code, to
apply the EPA look and feel to their applications.

•	EPA Native and Hybrid Mobile App Look and Feel Guidance - Describes the look and
feel requirements for mobile hybrid and native mobile applications.

Section 3(a)(3) Eliminate Redundancy

Identifying and eliminating content that is redundant, outdated, or trivial (ROT) is an important
part of regular review. ROT interferes with search results and makes it harder for people to find
what they are looking for, erodes the credibility and authority of EPA web content, increases
costs for maintenance and data storage, and makes site management more time-consuming and
burdensome.

EPA's Web Governance provides a framework for reviewing and approving websites before they
are set up. The EPA has provided tools and resources to staff to ensure implementation of this
requirement and to prevent redundancy. EPA will remain focused on acquiring and implementing
Web Analytics tools to provide more detailed measurements of ROT.

Initiatives that support this requirement include:

•	EPA ROT Guidance - Domain owners and web content managers must follow this EPA
guidance which explains steps that content owners must take to review content and
remove redundant, outdated, and/or trivial information.

•	EPA Content Review and Approval Process - EPA's Office of Web Communications
reviews all new or redesigned web content before it is published. This review helps
prevent redundant content from being published.

Section 3(a)(4) Make Information Searchable and Discoverable

Search functions are important to improving the web visitor experience and for reaching users
who primarily rely on commercial search engines to find information.

Search compliance was determined by on-site reviews. Websites with search engines were

10


-------
considered compliant and ones without it non-compliant.

Initiatives that support this requirement include:

•	EPA Search Engine - EPA is currently using the Lucid Works Fusion Search Engine.
The Search interface is built into the standard template, so search appears on every
page. EPA's search collection is available to both EPA's search engine and external
search engines such as Google and Bing.

•	Guidance on Coding forms for Metadata Search - EPA provides content owners with
guidance on coding their content to include the proper metadata to improve
discoverability.

•	Reducing Search Exits - EPA uses web analytics data to identify the number of search
exits so we can take step to improve our search engine. Reductions in search exits
indicate that website visitors are finding the information they need using the search
engine.

•	Reducing Search Refinement - EPA uses web analytics data to identify the number of
search refinements to improve the agency's search engine. Reductions in search
refinements indicate that website visitors are finding the information they need with fewer
searches.

•	Best Bets - EPA reviews the Foresee survey results and Google Analytics data to find
popular search terms and manually updates the list of "Best Bets" to ensure that best
results show up first.

Section 3(a)(5) Use Secure Connections

EPA takes steps to ensure that all offices within the Agency meet the minimum-security
requirements defined in the Federal Information Processing Standards (FIPS) Publication 200.
Existing sites on www.epa.gov have been transitioned to HTTPS and any new sites will be
HTTPS as well. The EPA has tools and staff dedicated to ensuring implementation of this
requirement on www.epa.gov.

The secure connections compliance was determined by using the results from the IT Dashboard
Report dated October 31, 2023. The websites secure connections compliance was measured by
different metrics such as: enabling and enforcing Hypertext Transfer Protocol Secure (HTTPS),
and enabling HTTP Strict Transport Security (HSTS). Websites that satisfied these metrics
above were considered compliant.

Initiatives that support this requirement include:

•	DHS CISA Report - This report measures the presence and enforcement of HTTPS for
Environmental Protection Agency's publicly accessible domains and subdomains.

•	Information Security Program - EPA's Information Security Program oversees and
coordinates implementation of policies, procedures, standards, and guidance to ensure
that EPA's websites meet minimum federal website security management requirements.

•	EPA's Information Security Policy - This policy establishes a security policy for EPA's
national data communications network.

11


-------
• Procedure: Obtaining an EPA.gov Subdomain - EPA's procedure for registering new
subdomains helps ensure that all new sites comply with the HTTPS requirement.

Section 3(a)(6) Data Driven Design

EPA is dedicated to using quantitative and qualitative data to drive improvements to our website.

The data driven design compliance was determined by using the results from the IT Dashboard
Report dated October 31, 2023. GSA's Site Scanning is used to obtain the Digital Analytics
Program (DAP) website participation. The DAP is a central, shared web analytics service for
federal agencies of the United States Government, managed by GSA. Website participating in
the DAP Program were considered DAP compliant and non-participant websites were
considered non-DAP compliant.

Initiatives that support this requirement include:

•	Digital Dashboard Report for DAP - Google Analytics reports EPA web stats to the
GSA Digital Analytics Program (DAP).

•	Procedure: Google Analytics (GA) Event Tracking - EPA has a procedure that requires
google analytics code on all public web content so we can provide usable data to the DAP.

•	Web Analytics - EPA also uses Google Analytics for web traffic and the Foresee survey
for user feedback. Both tools are on the list of GSA-approved tools, so they comply with
the OMB requirements and are approved for federal use.

•	Web Analytics Training - EPA offers a variety of courses on web management best
practices and using web analytics data to drive website improvements.

Section 3(a)(7) Customization

EPA's Central Data Exchange (CDX) is the only domain that provides a more customized digital
experience by allowing users to login and complete digital transactions in an efficient and
accurate manner.

The customization compliance was determined by on-site reviews. Websites with a login screen
were considered compliant. However, this requirement is optional so websites without a login
screen were not consider non-compliant.

Section 3(a)(8) Provide Access to Government Information on Multiple
Devices; Mobile-Ready

Mobile sites and applications can provide increased visibility to the Agency's mission, while also
helping us provide value to our external stakeholders.

The mobile-ready results were collected from the IT Dashboard Report dated October 31, 2023.
The results were based on a usability status (i.e., mobile friendly, not mobile friendly). Mobile
friendly websites were considered compliant and not mobile friendly non-compliant.

•	Mobile Application Development Strategy - EPA's Mobile Application Development
Strategy provides guidance on mobile app development and outlines the various
development options including Mobile Web App Development, Hybrid App Development,
and Native Mobile App Development.

12


-------
•	Web Standards: Look and Feel Template - EPA's standard template provides a
responsive design so that EPA web content can be displayed on a variety of devices and
window or screen sizes.

•	EPA Native and Hybrid Mobile App Look and Feel Guidance - Describes the look and
feel requirements for mobile hybrid and native mobile applications.

Cost Estimation Methodology

The numbers of hours estimated to bring websites into compliance were projected based on best
estimates from the domain owners. The dollar estimates were calculated based on an
assumption of an average of $165 per hour contracting rate. As EPA moves forward with website
modernization, the Agency will refine these estimates.

Table 5: Domains Estimated Costs and Schedules

From Table 1, EPA has prioritized the following websites and digital services. The table below
includes an estimated cost of modernization to comply with the requirements in section 3(a) of
the 21st Century IDEA, as well as other federal web management requirements (such as:
Privacy, Quality, Records Management, Plain Language, Multilingual Content, Mandatory
Content, and IPv6).

Appendix A

The following is a list of EPA's external domains and subdomains. This report contains objective
data about domains and subdomains included in GSA's IT Dashboard. EPA used data from
itdashboard.gov to provide objective data about domain and subdomain compliance with Federal
web management requirements. EPA needs to acquire additional tools and devote additional
resources to obtain accurate measurements for 800+ internal and external subdomains (except
for www.epa.gov, which already has dedicated tools and resources).
