Evaluation of Pennsylvania's Phase III Watershed Implementation Plan (WIP)
Executive Summary
The U.S. Environmental Protection Agency (EPA) has completed the evaluation of Pennsylvania's
Phase III Watershed Implementation Plan (WIP). EPA's review of Pennsylvania's Phase III WIP found
areas in which the Commonwealth addressed the expectations set by the Chesapeake Bay Program
(CBP) partnership and other areas where the plan needs additional documentation.
Pennsylvania, which was one of the original signatories of the Chesapeake Bay Agreement and long-
standing active participant in the CBP partnership, has continued to commit to the goal of a clean
Chesapeake Bay by initiating and agreeing to actions to achieve that goal. EPA recognizes that
Pennsylvania's challenges in meeting its CBP partnership Chesapeake Bay Total Maximum Daily Load
(Bay TMDL) goals are greater and different than the other jurisdictions. The Commonwealth had the
greatest responsibility for nutrient reductions since the release of the Bay TMDL, and Pennsylvania's
local governmental structure may require an additional level of coordination and collaboration when
restoring water quality on a watershed basis. Pennsylvania's ground-up, stakeholder-driven process for
developing its Phase III WIP was noteworthy. Hundreds of watershed stakeholders were engaged in the
Phase III WIP development process to assess barriers to watershed implementation and explore creative
strategies to overcome them.
EPA recognizes the leadership of the agriculture sector in providing recommendations for commitments
to help meet the Bay restoration goals. These recent efforts and contributions from agriculture resulted
in significant, positive momentum for the development of the Phase III WIP. Success in this sector in
Pennsylvania, is key to the overall success of Pennsylvania's contribution to the CBP partnership's
restoration effort.
EPA also recognizes the contribution and leadership of other sectors and stakeholders in providing
recommendations for commitments to help meet the Bay restoration goals. Through the pilot County
Action Plan efforts in Lancaster, York, Adams, and Franklin Counties, Pennsylvania provided a
comprehensive road map for these counties in the watershed and developed an effective method for
targeting areas for locating pollutant reduction practices that achieve the most effective and efficient use
of grant dollars. These efforts also resulted in significant, positive momentum toward successful
watershed restoration.
Pennsylvania's Phase III WIP meets its numeric planning targets for phosphorus and 75% of its numeric
planning targets for nitrogen at the state and state-basin (Susquehanna, Potomac, Eastern Shore, and
Western Shore) levels through the submission of best management practices (BMPs) and wastewater
reductions. EPA recognizes that Pennsylvania has the largest loads to account for within the Chesapeake
Bay, nevertheless the actions in the Phase III WIP will help improve the health of local streams and the
Bay. However, Pennsylvania's current planned efforts do not achieve the nitrogen Phase III WIP
planning target, nor does the plan explain how or when additional reductions from the remaining County
Action Plans will be incorporated into the broader plan to achieve the nitrogen planning target. EPA
recommends that to continue to honor its commitment to meet the partnership's Bay TMDL planning
goals for nitrogen by the 2025 date, Pennsylvania may want to seize upon the stakeholder momentum,
reconsidering the sector workgroup recommendations, and develop numeric 2020 - 2021 milestones that
are based on implementing programs and practices to meet 100% of the planning target for nitrogen by
2025. EPA stands ready to assist in that development in any way possible, including continuing to work
with the sector workgroups in developing milestones that fully address Pennsylvania's commitments to
meet the Bay restoration goals.

-------
Pennsylvania
In its Phase III WIP Pennsylvania identified implementation of nine specific agricultural BMPs that
account for 76% of the WIP nitrogen load reduction moving forward. For confidence that the planned
load reductions will occur, Pennsylvania's WIP could have included detailed explanations about how
Pennsylvania will strengthen these practices and programs including the inspection and maintenance of
the BMPs already implemented. These concerns could be addressed through development of specific
and detailed numeric targets for BMP implementation in selected source sectors. EPA recommends
Pennsylvania include two-year numeric BMP implementation targets for these nine practices as part of
its programmatic milestones.

Evaluation of Pennsylvania's Phase III Watershed Implementation Plan (WIP)
Background
The seven jurisdictions (Delaware, the District of Columbia, Maryland, New York, Pennsylvania,
Virginia, and West Virginia) in the Chesapeake Bay Program (CBP) partnership agreed to develop
Watershed Implementation Plans (WIPs) in three phases to provide a framework for reducing nitrogen,
phosphorus, and sediment loads to meet water quality standards in the Chesapeake Bay and its tidal
tributaries. The CBP partnership established the goal to have all practices in place by 2025 that were
necessary to achieve applicable water quality standards in the tidal Bay. The Chesapeake Bay Total
Maximum Daily Load (Bay TMDL), which is an informational planning tool, established goals to be
met using the CBP partnership's timeline of 2025. In 2010, EPA worked with the CBP partnership to
establish the Bay TMDL based primarily on the Phase I WIP commitments made by each of the Bay
jurisdictions. Pennsylvania agreed to develop Phase II and Phase III WIPs to set out an adaptable
approach for achieving the pollutant reductions and programmatic commitments that Pennsylvania
intended to implement in each Phase so that it would meet its commitment to the CBP partnership's
2025 goals.
The CBP partnership agreed that EPA should help provide accountability and assess whether (1) each
jurisdiction's WIP sets out sufficient commitments to meet the 2025 goals and (2) whether there is an
adequate level of confidence that the jurisdiction will achieve those specific commitments. While EPA
does not approve or disapprove a WIP, EPA provides the assessment for the benefit of the CBP
jurisdictions, and, as appropriate, may provide additional recommendations for strengthening the WIP or
its components. EPA evaluated Pennsylvania's Phase III WIP to assess whether Pennsylvania
commitments will meet the 2025 statewide and state-basin Phase III WIP planning targets and whether
Pennsylvania included sufficient information in the WIP to provide confidence that Pennsylvania will
achieve these targets by 2025.
Overview
In reviewing Pennsylvania's Phase III WIP, EPA found areas in which the Commonwealth addressed
the goals of the Bay TMDL and the expectations set by the partnership. Using the CBP partnership's
suite of modeling tools, simulations indicate that full implementation of Pennsylvania's plan is expected
to achieve 100% of the statewide and state-basin (Susquehanna, Potomac, Eastern Shore, and Western
Shore) Phase III WIP planning targets for phosphorus and 75% of the statewide planning target for
nitrogen. Pennsylvania's plan achieves the nitrogen target in the Western Shore basin. However,
modeling simulations indicate that the plan will not achieve nitrogen targets in the Susquehanna,
Potomac, or Eastern Shore basins1.
Additionally, Phase III WIP planning targets for sediment were approved by the CBP partnership's
Management Board on October 17, 2019 and recommended to the Principals Staff Committee (PSC) for
final approval. In its Phase III WIP, Pennsylvania committed to provide an addendum to its Phase III
WIP once the PSC approves these sediment targets. The sediment target addendum will not affect the
BMPs called for in the WIP and are not intended to be the driver for implementation moving forward.
1 Each jurisdiction has the option of adjusting its Phase III WIP state-basin planning targets through nutrient exchanges and/or exchanges
with other basins within that jurisdiction. Consistent with commitments Pennsylvania agreed to through the CBP partnership, any
adjustments to the state-basin planning targets must still result in all 92 Chesapeake Bay segments achieving the respective jurisdictions'
Chesapeake Bay water quality standards under Phase 6 Chesapeake Bay airshed, watershed, and estuarine water quality/sediment transport
model simulated conditions.

Some of the notable strengths identified in the Phase III WIP include:
•	Pennsylvania conducted outreach and community engagement efforts to develop the Phase III WIP.
Hundreds of watershed stakeholders were involved in the Phase III WIP development process to
assess barriers to watershed implementation and creative strategies to overcome them.
•	Through the pilot Countywide Action Plan efforts in Lancaster, York, Adams, and Franklin
Counties, Pennsylvania provided a comprehensive plan for the counties in the watershed and
represented an effective use of targeting areas for pollutant reduction practices. Should the proposed
state funding initiative materialize, the Countywide Action Plan rollout to the Tier 2, 3, and 4
counties would accelerate the pace of BMP implementation going forward.
•	Pennsylvania committed to initiate implementation of the Pennsylvania Ag Conservation
Stewardship program by January 2020 that will recognize producers who document, with proper
verification, practices demonstrating compliance with state regulatory requirements as well as all
recommended Phase III WIP practices applicable to their operations.
•	Pennsylvania clearly defined the funding and resource gaps necessary to address the numeric
planning targets.
•	Pennsylvania's wastewater sector documents that the significant dischargers reached the 2025
nitrogen and phosphorus reduction goals in 2018, seven years ahead of schedule.
EPA's review, however, also noted remaining areas in the Phase III WIP that Pennsylvania could
address moving forward to satisfy its commitments to the CBP partnership in meeting the 2025 goals.
Generally, EPA recommends that Pennsylvania consider amending its Phase III WIP to include more
robust implementation details and programmatic commitments on the initiatives identified for achieving
commitments on nutrient reductions, including securing the necessary funding and staff, enacting
needed legislation, refining programs, and developing necessary regulatory changes.
EPA Oversight and Assistance-
As it has done since the release of the Bay TMDL, EPA plans to continue to commit staff, contractual,
and funding resources to support the implementation of Pennsylvania's Phase III WIP and future two-
year milestones. This support includes evaluation of the most-effective practices and locations, annual
WIP assistance funding to address priority implementation needs, evaluation of Pennsylvania's
implementation capacity under various staffing, funding, regulatory and programmatic scenarios, local
planning outreach, legislative and regulatory gap analysis, and monitoring trend analyses. In addition,
EPA will work with federal partners to provide leadership and coordinate with Pennsylvania on WIP
and two-year milestone implementation to reduce pollution from federal lands. EPA plans to continue its
commitment to track annual progress of Pennsylvania and all the other Bay jurisdictions, and make
those results available to the CBP partnership. [See: https://www.epa.gov/chesapeake-bav-tmdl/epa-

Although Pennsylvania made a commitment to the CBP partnership that it will achieve its numeric
planning targets for phosphorus and nitrogen at the state and state-basin (Susquehanna, Potomac,
Eastern Shore, and Western Shore) levels through the implementation of best management practices

(BMPs) and wastewater reductions, Pennsylvania's Phase III WIP acknowledges that the programs and
practices to be implemented would result in achieving 75% of its numeric planning targets for nitrogen.
The Phase III WIP suggests additional measures that may be pursued to close the nitrogen reduction gap
through adaptive management, such as the completion of the remaining Countywide Action Plans over
18 months, improved documenting, tracking, and verification of existing practices and programs, and
through accreditation of new practices that reduce nutrients and sediment. However, the Phase III WIP
does not provide a clear commitment or timeline for the implementation of those suggestions.
In our role to help Pennsylvania improve its accountability to the CBP partnership in meeting its
commitment to the 2025 goals, EPA recommends that the following be included in Pennsylvania's 2020
- 2021 milestones to enhance the Phase III WIP as submitted and at the same time address the
Commonwealth's recognized nitrogen reduction gap.

Detailed Evaluation of Overall Load Reduction and Source Sectors
The following sections provide specific highlights of key strengths of Pennsylvania's Phase III WIP.
These sections also highlight areas for enhancement to assist Pennsylvania in implementing its Phase III
WIP and subsequent two-year milestones to provide confidence that Pennsylvania will have programs
and practices in place by 2025 to achieve its Phase III WIP planning targets.
Load Reduction Review
When evaluating Pennsylvania's Phase III WIP numeric commitments, EPA modeled implementation
scenarios through the CBP partnership's Phase 6 suite of modeling tools and compared those simulated
nutrient3 loads to Pennsylvania's 2025 statewide and state-basin Phase III WIP planning targets. In its
June 21, 2019 evaluation, EPA noted that Pennsylvania's implementation scenario, which used 2018
flows for wastewater treatment plants to represent 2025 conditions in its Phase III WIP, was not
reflected in its draft Phase III WIP. This error was corrected in the Phase III WIP.
In the Phase III WIP document, Pennsylvania states that it "commits to have all practices and controls in
place by 2025 necessary to achieve the Phase III WIP for phosphorus and nitrogen." However,
simulations indicate that full implementation of Pennsylvania's WIP is expected to achieve 100% of the
statewide and state-basin (Susquehanna, Potomac, Eastern Shore and Western Shore) Phase III WIP
planning targets for phosphorus and 75% of nitrogen. State-basin targets were met for phosphorus and
any excess was exchanged to address some nitrogen.4 The state-basin target for nitrogen was met in the
3	Phase III WIP planning targets for sediment were developed by the CBP partnership after the Phase III WIP submittal. Pennsylvania
committed to address the sediment targets approved by the CBP partnership and to amend its Phase III WIP once the CBP partnership
approves these sediment targets.

with other basins within that jurisdiction. Any adjustments to the state-basin planning targets must still result in all 92 Chesapeake Bay

Western Shore. However, modeling simulations indicates that the plan will not achieve nitrogen targets
in the Susquehanna, Potomac, or Eastern Shore basins.
Pennsylvania proposes to achieve most of its pollutant reductions by implementing BMPs in the
agricultural sector: 92% for nitrogen and 72% for phosphorus. Pennsylvania plans to maintain the
progress it has made in pollutant reductions from the wastewater sector. Pennsylvania proposes the
remainder of the pollutant reductions to come from existing programs for stormwater management and
the natural sector which includes preservation of forests and wetlands and controls on stream bed and
bank loads. Finally, Pennsylvania's Phase III WIP addresses each of the additional changing and local
conditions identified by the CBP partnership.

of the following initiatives: partnering with NGOs on voluntary conservation, market-based
approaches, pay for performance approaches, public-private partnerships, and improving regulatory
compliance.
•	Pennsylvania identified a proposal to modify the Agriculture Erosion and Sediment Control
Regulations; EPA recommends that Pennsylvania explain how or when this modification would
occur.
Stormwater
Key Strengths
Key strengths in the Phase III WIP include:
•	Pennsylvania included additional programs to improve tracking and reporting of erosion and
sediment control practices to achieve the phosphorus reduction targets and to help meet the sediment
reduction targets.
•	Pennsylvania provided detailed staffing and funding numbers for multiple state agencies to show
what additional resources are needed to meet its restoration goals. The Phase III WIP also discusses
proposals to maintain a dedicated funding source for Chesapeake Bay restoration.
•	Pennsylvania proposed fertilizer legislation that would reduce nitrogen and phosphorus runoff to the
Chesapeake Bay.
•	Pennsylvania solicited feedback from the public and other stakeholders in the Phase III WIP process,
including through a dedicated stormwater workgroup in preparing the Phase III WIP.
•	Pennsylvania commits to updating its Stormwater BMP Manual, which will include updated
calculations for BMPs related to water quality, rate, and volume.
•	Pennsylvania commits to prioritizing Act 167 compliance and enforcement and will undertake
education and outreach related to the benefits of implementing the Act.
•	Pennsylvania commits to improve reporting and verification procedures. The new Pennsylvania
verification strategy fills a gap for the urban sector with new verification procedures, as well as the
pending improvements to the BMP Warehouse and Practice-Keeper reporting systems, that will
support Pennsylvania Muncipal Separate Storm Sewer Systems (MS4s) communities.
•	Pennsylvania emphasized practices that provide strong local co-benefits5. For example,
Pennsylvania envisions about 12 miles of stream restoration per year, and thousands of acres of
reforestation, buffers and urban tree canopy. These practices are also cost-effective and work best in
the rural and suburban areas of the Chesapeake Bay watershed.
5 Co-benefits are those that not only result in water quality improvements but could address other 2014 Chesapeake Bay
Watershed Agreement Outcomes (e.g., environmental problems, wetlands, or forest buffers), local water quality benefits, as
well as economic and ecosystem services benefits generated from restoration activities.

Key strengths in the Phase III WIP include:
•	Pennsylvania developed its implementation scenarios based on 2025 forecasted growth conditions,
per the CBP partnership decision.
•	Pennsylvania developed and refined its Land Policy BMP that is focused on land conservation
activities which will reduce nitrogen to the Bay.
•	Pennsylvania provided a framework to offset growth, which will be evaluated, tracked, and reported
in two-year milestones, including conserving and protecting wetlands; implementing conservation
practices and limiting development in riparian areas; modernizing local planning and zoning to
conserve critical forests and habitats; and preserving farmland as part of a holistic approach to
conserving working lands.

•	Pennsylvania described sector-level growth trajectories which establish a baseline for Pennsylvania's
strategies to reduce pollutants from growth.
In its Phase III WIP, Pennsylvania addressed the following potential enhancements that were suggested
by EPA in its draft Phase III WIP evaluation:
•	Pennsylvania provided additional estimates predicting how effective its septic inspection and
pumping programs will be in addressing growth, since septic system loads comprise nearly 25% of
expected growth in load from the developed sector and these programs are not currently being
tracked.
Enhancements
EPA recommends Pennsylvania address the following in its 2020-2021 milestones to satisfy its CBP
partnership commitments:
•	Describe how it will track new sediment and nutrient loads to ensure that the Phase III WIP planning
targets are not exceeded.
•	Pennsylvania is projecting a shift in the land use between 2017 and 2025 due to projected sector
growth that is included in the CBP partnership's Chesapeake Assessment Scenario Tool. EPA
recommends that Pennsylvania explain how it will maintain implementation levels necessary to
address changes in loads from the stormwater sector.
Climate
Key Strengths
Key strengths in the Phase III WIP include:
•	Pennsylvania documented its jurisdiction-specific 2025 numeric climate change loads based on
factors such as increasing precipitation and rising sea level in the Phase III WIP document.
•	Pennsylvania is working with Pennsylvania State University (PSU) to develop and update a study on
the impact of climate change in Pennsylvania specifically focusing on water quality impacts.
•	Pennsylvania outlined the actions and strategies it has undertaken to address climate change in recent
years.
Local Engagement Strategies
Key Strengths
Key strengths in the Phase III WIP include:
•	Pennsylvania conducted outreach and community engagement efforts to develop the Phase III WIP.
Hundreds of watershed stakeholders were involved in the Phase III WIP development process to
assess barriers to watershed implementation and devise creative strategies to overcome them.
•	Pennsylvania identified necessary resources for an agency support team that will work in a phased
approach to continue the development of the County Action Plans. As the County Action Plans are
completed, these technical resources will transition into assisting counties with implementing the
county plans to achieve the Phase III WIP goals.
•	Pennsylvania clearly defined current local stakeholders as well as plans to identify future local
stakeholders throughout the remaining counties.

Pennsylvania
•	Pennsylvania developed and implemented an extensive communication and engagement plan
throughout the development of the Phase III WIP.
•	Pennsylvania engaged stakeholders through large public venues, social media, and individual
outreach mechanisms.
•	Pennsylvania commits to providing programmatic progress updates using the Progress and Tracking
Template every six months via the Pennsylvania Chesapeake Bay WIP website.
In its Phase III WIP, Pennsylvania addressed the following potential enhancements that were suggested
by EPA in its draft Phase III WIP evaluation:
•	Pennsylvania explained how outreach will continue after the Phase III WIP is finalized.
•	Pennsylvania provided additional facilitation, technical and staff resources to support the local
engagement process across non-pilot counties.
Local Planning Goals
Key Strengths
Key strengths in the Phase III WIP include:
•	Pennsylvania developed local planning goals that are measurable and below the major state-basin
scale, following CBP partnership decisions, by developing numeric load reduction goals at the
county level across the entire Chesapeake Bay watershed portion of Pennsylvania.
•	Pennsylvania provided detailed information on how local planning goals were developed.
•	Pennsylvania demonstrated a commitment to continue to engage with local partners moving into
Phase III WIP implementation in counties that already have plans, as well as the remaining counties.
•	Pennsylvania developed methods by which to track and report progress from counties and has
demonstrated a commitment to work with the CBP partnership on refining these methods and tools.
•	Pennsylvania maintained focus on local water quality improvement.
•	Pennsylvania provided a mechanism to follow the status of the new program initiatives over the next
several years which will be a useful tool in analyzing future submissions for milestones and
progress.
•	Through the pilot County Action Plan efforts in Lancaster, York, Adams, and Franklin Counties,
Pennsylvania provided a comprehensive road map for the counties in the watershed and represented
an effective use of targeting areas for pollutant reduction practices. Should the proposed state
funding initiative materialize, the county wide action plan rollout to the Tier 2, 3, and 4 counties
would accelerate the pace of BMP implementation going forward.
•	Pennsylvania compiled applicable resources and materials for their local partners, such as the
Community Clean Water Guide and action plan templates.
Enhancements
EPA recommends Pennsylvania address the following in its 2020-2021 milestones to satisfy its CBP
partnership commitments:
•	Identify a process for how its Phase III WIP will be revised or amended to accommodate the
additional 39 County wide Action Plans as they are completed.
•	The Phase III WIP states that any additional reductions needed will be achieved through the
completion of the remaining Countywide Action Plans and statewide initiatives and activities that

have yet to be quantified. Since the four pilot Countywide Action Plans did not result in fully
meeting their targets, EPA recommends that Pennsylvania identify a process for how the remaining
counties will meet their targets, including a contingency plan in case the non-pilot counties cannot
make up for that gap to achieve the Phase III WIP planning targets by 2025.
Other Comments
Key Strengths
Key strengths in the Phase III WIP includes:
•	The Phase III WIP focuses on "local benefits" and the benefits discussed in the Countywide Action
Plans heavily overlap with co-benefits and the 2014 Watershed Agreement. EPA encourages
Pennsylvania to continue its focus on local solutions and implementation to achieve its Phase III
WIP planning targets.
Enhancements
EPA recommends Pennsylvania address the following in its 2020-2021 milestones to satisfy its CBP
partnership commitments:
•	Pennsylvania's Phase III WIP identifies the funding necessary to implement the WIP and lists
several options for generating the necessary funds through dedicated funding sources (i.e. the bottled
water tax) but does not indicate if any of the options are actively being pursued. EPA recommends
that Pennsylvania clarify what commitments are being made and how establishment of a dedicated
funding source for water quality improvements will be achieved.
•	Pennsylvania has made commendable commitments within the Progress and Tracking Template.
The Phase III WIP would be strengthened by adding linkages and details contained in the
supplemental documents to more effectively communicate the actions and plans. EPA recommends
that Pennsylvania's current gap analysis include more specificity, which is a strength of the
supplemental documents. A clear cross-reference would greatly assist the reader to understand
everything Pennsylvania partners have developed.
BMP Verification
•	Jurisdictions agreed to follow CBP partnership-approved BMP verification protocols when
developing and implementing the Phase III WIPs. Because Pennsylvania is proposing to increase
BMP implementation rates of some BMPs by 10-fold or more in the next seven years, EPA
recommends that the Commonwealth ensure that implementation at this higher rate can be tracked,
verified, and reported within that period in accordance with the agreed upon verification protocols,
or by another method established by the CBP partnership.
•	Regarding plans to conduct an inventory of data for BMPs that have already been implemented, it is
important that future reporting of this data include accurate implementation and inspection dates,
following the CBP partnership's verification protocols or another method established by the CBP
partnership.
•	The draft BMP verification plan included with the Phase III WIP materials suggests that many
programs and BMPs "potentially" have resources for verification. EPA recommends that the
resources for verification or opportunities to secure those resources be identified in the Phase III
WIP and Progress and Tracking Template.
