Evaluation of Virginia's Phase III Watershed Implementation Plan (WIP)
Executive Summary
The U.S. Environmental Protection Agency (EPA) is providing this evaluation of Virginia's Phase III
Watershed Implementation Plan (WIP). EPA's review of Virginia's Phase III WIP found the
Commonwealth largely addressed the goals of the Chesapeake Bay Total Maximum Daily Load (Bay
TMDL) and the additional expectations set by the Chesapeake Bay Program (CBP) partnership.
Through extensive local engagement, Virginia was able to build a strong coalition of stakeholders that
resulted in reduction plans at the local level that had the support of the local implementers. This
planning has resulted in 56 specific initiatives intended to meet the 2025 goal. Virginia's plan also
includes innovation in the form of new agricultural strategies, such as proposing legislation for nutrient
management and livestock exclusion should certain reduction goals not be attained. Virginia also
proposes to achieve additional reductions in the wastewater sector in the James River and Eastern Shore
basins. The Phase III WIP also includes additional proposals such as considering reevaluating the
municipal separate storm sewer (MS4) action plan guidance for addressing crediting of projects in
unregulated areas. And Virginia's Phase III WIP commits to address the reductions necessary to address
climate change now, in advance of the CBP partnership's goal of 2022.
Virginia's plan meets its numeric planning targets for nitrogen and phosphorus at the state and state-
basin (Potomac, Rappahannock, York, James and the Eastern Shore) levels through the submission of
Best Management Practices (BMPs) and wastewater reductions. Virginia's plan provides confidence in
its narrative submission (i.e., adequate funding and programs) that it will attain the necessary load
reductions by 2025 through the suite of BMPs and wastewater reductions proposed. The associated level
of confidence could be improved as further detailed in this evaluation.
In its evaluation of the Phase III WIP, EPA identified that Virginia will meet its planning targets and its
commitment through high rates of BMP implementation. In its Phase III WIP, Virginia identified eleven
specific BMPs that account for 60% of the WIP nitrogen load reduction moving forward. For confidence
the planned load reductions will occur, Virginia's WIP could have included detailed explanations about
how Virginia will strengthen these practices and programs, including the inspection and maintenance of
the BMPs already implemented. This could be addressed through development of specific and detailed
numeric targets for BMP implementation in selected source sectors. EPA recommends that
Virginia include 2-year numeric BMP implementation targets for these eleven practices as part of its
programmatic milestones.

Evaluation of Virginia'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 TMDL
(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. Virginia agreed to develop Phase II and Phase III WIPs to set out an adaptable approach
for achieving the pollutant reductions and programmatic commitments that Virginia 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 Virginia's Phase III WIP to assess whether Virginia commitments will
meet the 2025 statewide and state-basin Phase III WIP planning targets and whether Virginia included
sufficient information in the WIP to provide confidence that Virginia will achieve these targets by 2025.
Overview
In reviewing Virginia's Phase III WIP, EPA found many areas in which the Commonwealth addressed
the goals of the Bay TMDL and the additional expectations set by the CBP partnership. Using the CBP
partnership's suite of modeling tools, simulations indicate that full implementation of Virginia's plan is
expected to achieve 100% of the statewide and state-basin (Potomac, Rappahannock, York, James and
the Eastern Shore) Phase III WIP planning targets for nitrogen and phosphorus. State-basin targets were
met through exchanges of phosphorus to nitrogen.1
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, Virginia committed to address the sediment targets approved by the
CBP partnership and to provide an addendum to its Phase III WIP once the CBP partnership approves
these sediment targets. The Phase III WIP sediment targets will not affect the BMPs called for in the
WIP and are not intended to be the driver for implementation moving forward.
Some of the key strengths identified in the Phase III WIP include:
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 Virginia 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.

Virginia
Extensive local engagement which resulted in reduction plans at the local level that had the
support of the local implementers.
New agricultural strategies such as proposing legislation for nutrient management and livestock
exclusion should certain reduction goals not be attained. Virginia now commits to conducting a
pilot program to determine methods for locating stream exclusion fencing needs.
Proposal to achieve additional reductions in the wastewater sector in the James River and Eastern
Shore basins. While overall statewide phosphorus loads from this sector are expected to
decrease, statewide nitrogen loads from this sector are expected to increase slightly by 2025.
Proposal to continue the annual needs assessment for the agricultural sector and to perform
similar assessments in the stormwater sector and the wastewater sector. These assessments will
be used to provide information to the legislature on needed funding.
New proposals since submission of the draft Phase III WIP such as considering options for
additional no-discharge zones, advancing oyster restoration efforts, guiding land conservation to
lands with the highest conservation value, pursuing Sentinel Landscape Partnerships and
reevaluating the municipal separate storm sewer (MS4) action plan guidance for addressing
crediting of projects in unregulated areas.
EPA's review also noted potential enhancements that could increase confidence that Virginia's Phase III
WIP will attain the 2025 goals. These enhancements include:
•	Virginia can provide more detailed information on the funding needed and further define the
current funding gaps in its proposed agricultural and stormwater implementation programs for
the next 6 years.
•	Virginia can provide more detailed information on its commitment to pursue new legislation for
nutrient management plans and livestock exclusion if its goals are not achieved, but will not
begin any necessary rulemaking processes until after December 31, 2025.
•	Virginia states that overperformance of the wastewater sector will make up for slower
implementation in the more challenging sectors and that it is planning to reduce wastewater
sector loads through either upgrades or trading under its Watershed General Permit. However,
Virginia's implementation scenario shows a slight increase in nitrogen loads statewide from the
wastewater sector. We recommend that Virginia clarify this discrepancy.
•	Virginia could provide more detail on how pollution reducing techniques will be incentivized in
the unregulated portion of the stormwater sector and how the trading program will be used to
address stormwater reductions as over 70% of this sector is unregulated and Virginia's plan calls
for a 13% reduction in nitrogen loads from this sector from 2009 levels.
•	Virginia anticipates that both point source (e.g., wastewater) and non-point source (e.g.,
agriculture and stormwater) reductions called for in the James River to meet the dissolved
oxygen (DO) standard will also meet the new chlorophyll-a standards. While most of the
reductions anticipated are in the James River wastewater sector, Virginia may want to provide
additional programmatic and funding information for the non-point source sector to ensure that
all the anticipated reductions will be made.

EPA Oversight and Assistance-
As it has done since the release of the Bay TMDL, EPA will continue to commit staff, contractual, and
funding resources to support the implementation of Virginia's Phase III WIPs 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 Virginia'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
continue to work with federal partners to provide leadership and coordinate with Virginia on WIP and
two-year milestone implementation to reduce pollution from federal lands. EPA plans to continue its
commitment to track annual progress of Virginia and all the other Bay jurisdictions and make those
results available to the CBP partnership. [See: https://www.epa.gov/chesapeake-bav-tmdl/epa-

Detailed Evaluation of Overall Load Reduction and Source Sectors
The following sections provide specific highlights of key strengths of Virginia's Phase III WIP. These
sections also highlight areas for improvement to assist Virginia in implementing its Phase III WIP and
subsequent two-year milestones to provide confidence that Virginia will have programs and practices in
place by 2025 to achieve its Phase III WIP planning targets.
Load Reduction Review
When evaluating Virginia'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 Virginia's 2025 statewide and state-basin Phase III WIP planning targets.
Simulations using that scenario indicate that full implementation of Virginia's plan is expected to
achieve 100% of the statewide and state-basin (Potomac, Rappahannock, York, James and the Eastern
Shore) Phase III WIP planning targets for nitrogen and phosphorus. State-basin targets were met through
exchanges of phosphorus to nitrogen.4
Virginia also made numeric reduction commitments to address climate change (i.e., 1.72 million pounds
of nitrogen and 0.19 million pounds of phosphorus). EPA determined that the additional climate change
reduction commitments (with the associated nutrient exchanges and state-basin exchanges) will achieve
dissolved oxygen water quality standards in the Chesapeake Bay and its tidal tributaries.
EPA plans to continue to work with Virginia to determine the impact on its Bay commitments resulting
from the proposed modifications to the numeric chlorophyll-a criteria applicable to the tidal James
River. Since the submission of the draft Phase III WIP, Virginia provided a public comment period for
amendments to its water quality standards regulations to modify and add site-specific chlorophyll-a
criteria applicable to the tidal James River. EPA received the final criteria package by Virginia on
November 12, 2019. EPA is currently reviewing and will make a final decision on any amendments to
these water quality standards before they become final for purposes of the Clean Water Act. Virginia
anticipates that its plan to meet the dissolved oxygen standards in the James River through reductions in
both the point source and non-point source sectors will also meet the new chlorophyll-a standards.
3	Phase III WIP planning targets for sediment were developed by the CBP partnership after the Phase III WIP submittal. Virginia
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.
4	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. 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.
7	December 19, 2019

-------
Virginia
Virginia proposes to achieve most of its pollutant reductions by implementing BMPs in the agricultural
sector: 76% for nitrogen and 56% for phosphorus. The remainder of the pollutant reductions are to
come primarily from enhancements to existing programs for stormwater management and the natural
sector which includes preservation of forests and wetlands and controls on stream bed and bank loads.
Virginia also proposes to shift reductions between sectors through enhancement and implementation of
its existing program for trading and offsetting. Finally, Virginia's Phase III WIP addresses each of the
additional changing and local conditions identified by the CBP partnership.
Source Sectors
Agriculture
Key Strengths
Key strengths in the Phase III WIP include:
•	Commitment to conduct a pilot program in one county to determine where to target stream exclusion
measures and providing additional detail on how to incentivize stream exclusion through its
agricultural cost share program (e.g., flexibility in buffer width, length of contracts, payment rates).
•	Commitment to explore alternative uses of poultry litter.
•	Virginia conducted a thorough review of its agricultural cost share program (VACS), solicited
recommendations from the Soil and Water Conservation Districts (SWCDs), formed subcommittees
to fully vet recommendations, and is advancing the consensus recommendations and refining the
program in 2019, 2020, and 2021.
•	Virginia proposes to enhance coordination of state agency activities and funding through a
formalized letter of agreement to better assist farmers, including identifying capacity needs.
•	Commitment to continue to conduct its annual needs assessment to ensure appropriate resources for
meeting WIP commitments.
•	Commitment to refining its Resource Management Plan (RMP) program to maximize
implementation.
•	Commitment to pursuing new legislation to ensure accelerated implementation of agricultural
practices such as increasing nutrient management plans on agricultural lands and legislation
establishing a date by which all farms with livestock accessing perennial streams must provide
exclusion measures.
In its Phase III WIP, Virginia addressed the following potential enhancements that were suggested by
EPA in its draft Phase III WIP evaluation:
•	Virginia expanded on its reinstatement of the agricultural BMP loan program by explaining such
things as the incentives for participation (e.g., zero percent interest, no long-term loan requirement
and the possibility for principal forgiveness).
•	Virginia provided additional detail on incentives beyond the current 100% cost share that will
enhance farmer participation in its livestock exclusion proposal, such as flexibility in buffer width,
length of contracts and payment rates to incentivize stream exclusion and proposed a pilot in one
county to determine where to best target stream exclusion measures.
•	Virginia clarified the timeframes for initiating proposed legislation for nutrient management. The
draft Phase III WIP noted that the regulatory requirement would be initiated "within 6 months" but
the final WIP indicates that that initiation will not begin until December 2025.
•	Virginia described its process for targeting BMP implementation in the higher loading counties.

December 19, 2019

-------
Virginia
Enhancements
EPA recommends Virginia address the following in its 2020-2021 milestones to satisfy its CBP
partnership commitments:
•	Virginia is replacing the draft Phase III WIP proposal to annually track progress towards meeting the
nutrient management goals in order to determine the need for nutrient management legislation and
then initiate this legislative process within 6 months of an off-track determination. The Phase III
WIP replaces that commitment with a plan to pursue legislation if the goals are not achieved by
December 31, 2025. In addition, Virginia now states that this legislative effort will consider the
availability of cost-share funds and capacity of certified nutrient management plan developers. EPA
recommends that Virginia track and report on the implementation rates for nutrient management.
•	Virginia states it will not initiate any necessary proposed legislation for livestock exclusion until
after December 31, 2025, the date by which Virginia will determine if its livestock exclusion goals
are not attained. EPA recommends that Virginia should track and report on the implementation rates
for livestock exclusion.
•	In its Phase III WIP, Virginia provided information (e.g., new strategies, legislative programs,
incentive programs, compliance programs, and/or funding mechanisms) on such initiatives as its
BMP loan program, VACS revisions, technical assistance funding, and its tax credit program.
However, Virginia should provide additional information to demonstrate how Virginia will support
the proposed implementation levels.
•	Virginia's final WIP provides additional information on the number of counties that could receive
poultry litter in its poultry litter transport program. EPA recommends Virginia provide details on
whether farmers in those counties are willing to use the litter and what additional funding will be
necessary to support more transport.
Stormwater
Key Strengths
Key strengths in the Phase III WIP include:
•	Reevaluating the baseline requirements in the MS4 TMDL action plan guidance to see if BMPs can
be put on unregulated land and credited under the MS4 permit.
•	Proposing a new initiative. Sentinel Landscapes Partnerships, a federal, local and
private collaboration dedicated to promoting natural resource sustainability in areas surrounding
military installations.
•	Utilizing the expertise of SWCDs, Planning District Commissions (PDCs) and local governments to
determine the most feasible BMP implementation rates for the localities.
•	Preparing an annual "needs assessment" for the stormwater sector (both regulated and non-
regulated) to present to the General Assembly to secure appropriate funding to assist in achieving
reduction goals.
•	An established trading program to achieve nutrient and sediment reduction goals in the stormwater
sector (as well as other sectors) and anticipates greater use of this program during Phase III WIP
implementation and beyond.
•	Plan to initiate a regulatory action to amend the erosion and sediment regulations to require nutrient
management planning for regulated land disturbing activities greater than or equal to one acre.
•	Plan to initiate a review of post-development design criteria to determine whether these criteria
continue to satisfy the Bay TMDL assumption that new or increased loads will be offset.

December 19, 2019

-------
Virginia
•	Commitment to load reductions for BMPs managing stormwater on non-municipal separate storm
sewer systems in addition to those regulated by MS4 permits.
•	Virginia established the key role of PDCs and SWCDs for both large and small communities in BMP
implementation.
•	Plan to expand the focus on forestry practices in both rural and urban areas (e.g., tree planting, urban
tree canopy, forested stream buffers and other green practices).
In its Phase III WIP, Virginia addressed the following potential enhancements that were suggested by
EPA in its draft Phase III WIP evaluation:
•	Virginia provided a link to its website for a full listing of all its NPDES permits having individual
wasteload allocations or that are part of aggregate wasteload allocations, such as stormwater
individual and general permits.
•	Virginia stated that its Stormwater Management Program (VSMP) regulations considers nitrogen
because nitrogen is calculated based on the phosphorus reductions.
•	Virginia provided additional details on technical assistance for its proposed higher demand for new
forestry practices, as well as details on its Tree City USA and tree conservation programs
•	Virginia committed to targeting practices in higher loading counties and to adaptively manage this
process.
Enhancements
EPA recommends Virginia address the following in its 2020-2021 milestones to satisfy its CBP
partnership commitments:
•	Virginia has indicated that "Any gap in this sector meeting its permit requirements by 2025 that are
due to timing will be offset by the excess capacity achieved in the wastewater sector." EPA
recommends Virginia clarify the magnitude of the gap that is expected to be offset by the excess
capacity achieved in the wastewater sector.
•	EPA recommends Virginia provide additional information on its funding needs and gaps, including
estimated funding, technical assistance, and staffing, required to achieve the (increased)
implementation levels called for in the Phase III WIP as Virginia has committed to do in its two-year
milestones.
•	EPA recommends Virginia clarify how its trading program for the MS4 community will be
incentivized and from where generated credits will be purchased.
Wastewater
Key Strengths
Key strengths in the Phase III WIP include:
•	Commitment to annually conduct a "Wastewater Needs Assessment" beginning in fiscal year 2020
to estimate Water Quality Improvement Fund funding expected by local governments for eligible
wastewater treatment projects.
•	Commitment to provide incentives to reduce loads from this sector through various septic initiatives.
In its Phase III WIP, Virginia addressed the following potential enhancements that were suggested by
EPA in its draft Phase III WIP evaluation:
10
December 19, 2019

-------
Virginia
•	Virginia provided some clarification on how and when the new requirements for additional
reductions related to the proposed chlorophyll-a standards for the James River will be incorporated
into the Watershed General Permit.
•	Virginia provided additional detail on its assumption that wastewater treatment plants will be
operating at the 2018 actual flowrates in 2025. Virginia provided a link to a listing of all its NPDES
permits (VPDES individual and general permits) that are part of its Phase III WIP major river-basin
targets and have individual wasteload allocations and/or are part of aggregate wasteload allocations.
•	Virginia clarified how and when the James River chlorophyll-a water quality standards will be
finalized. Virginia also clarified that additional modeling will be needed to confirm that the DO-
based wasteload allocations are protective of the revised chlorophyll-a criteria.
•	Virginia provided a summary of its planned watershed reductions including how the additional
nitrogen reductions in the James River will be exchanged with the other four basins to, in part,
address its climate change commitments.
•	Virginia committed to develop a plan to transfer oversight for annual alternative on-site sewer
inspections from local governments to the Department of Health.
Enhancements
EPA recommends Virginia address the following in its 2020-2021 milestones to satisfy its CBP
partnership commitments:
•	Virginia committed to require additional reductions from wastewater treatment plants in the James
River and Eastern Shore basins through either facility upgrades or trading under the Watershed
General Permit. Statewide, Virginia anticipates a slight increase in actual nitrogen loads and an
increase in actual nitrogen loads in the remaining three basins. EPA recommends Virginia describe
how these reductions will ensure that any gap in needed reductions is addressed in all basins. For
example, Virginia could identify in its list of permits which facilities will achieve the additional
reductions.
•	EPA recommends Virginia provide detailed information on the planned Phase III WIP wastewater
and non-wastewater reductions in the James River needed to meet the Dissolved Oxygen (DO) and
the new chlorophyll-a criteria.
Trading & Offsets
Key Strengths
Key strengths in the Phase III WIP include:
•	Virginia provides permittees subject to MS4 requirements opportunities to take advantage of point
source and nonpoint source trading programs to achieve their nutrient and sediment reduction goals.
Federal Facilities
Key Strengths
Key strengths in the Phase III WIP include:
•	Virginia included information on detailed collaboration with Department of Defense (DoD) and
included a description of DoD's activities and commitments for the draft Phase III WIP.
•	Virginia included a federal facility discussion in each basin-specific section of the draft Phase III
WIP, which is a strong improvement over the Phase II WIP.

Virginia
•	Virginia provides ongoing support and leadership in the CBP partnership's Federal Facilities
Workgroup.
In its Phase III WIP, Virginia addressed the following potential enhancements that were suggested by
EPA in its draft Phase III WIP evaluation:
•	Virginia incorporated information provided by United States Forestry Service, Fish and Wildlife
Service, and National Park Service, National Aeronautics and Space Administration, and Langley
Air Force Base in its Phase III WIP. Virginia will assume that all lands addressed by agencies which
did not provide information will meet their planning goals.
Changing and Local Conditions
Growth
Key Strengths
Key strengths in the Phase III WIP include:
•	Development of implementation scenarios based on 2025 forecasted growth conditions, per the CBP
partnership decision.
•	Virginia plans to initiate a review of the stormwater construction post-development water quality
design criteria requirements established under the VSMP Regulation, 9VAC25-870-63 in 2011 for
phosphorus. Virginia's review will determine if the criteria continue to satisfy the assumption of the
Bay TMDL that any new or increased loads will be offset.
In its Phase III WIP, Virginia addressed the following potential enhancements that were suggested by
EPA in its draft Phase III WIP evaluation:
•	Virginia provided additional language on how it is accounting for growth, why it used 2018 current
flow as an estimate for the 2025 expected flow from its wastewater treatment plants, and why it did
not choose to use the land use scenario it designed to address future growth beyond the current
zoning baseline.
•	Virginia committed to include milestones to track, discuss and address growth, as needed.
Climate
Key Strengths
Key strengths in the Phase III WIP include:
•	Virginia 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 and committed to address
these numeric loads now, as opposed to in its 2022-2023 milestones.
•	Commitment to several actions to address climate resilience.
Local Engagement Strategies

Virginia
•	Virginia's Soil and Water Conservation Board approved the creation of an Allocation Subcommittee
to fairly distribute technical assistance funding to all SWCDs.
•	Conducted outreach beginning in January 2017 to engage local partners in the development of the
Phase III WIP through training seminars, meetings, webinars, and the development of a Phase III
WIP webpage.
•	Engaged not only SWCDs, PDCs, and local governments but also conservation groups and other
non-governmental organizations, citizens, federal and state agencies, and utilities.
•	Utilized the expertise of SWCDs, PDCs and local governments to determine the most feasible BMP
implementation rates for the localities.
•	Articulated a plan for on-going engagement during Phase III WIP implementation, including
entering into contracts with the PDCs.
•	Maintained a Chesapeake Bay Stakeholder Advisory Group to seek input from local governments,
the agriculture and conservation communities, wastewater agencies, and private businesses and
industry on the Phase III WIP.
•	Incorporated input from seven local government roundtables held across the watershed and
sponsored by the CBP partnership's Local Government Advisory Committee in its draft Phase III
WIP.
In its Phase III WIP, Virginia addressed the following potential enhancements that were suggested by
EPA in its draft Phase III WIP evaluation:
•	Virginia provided additional details on how increased capacity and funding needs will be tied to the
PDCs and SWCDs. Virginia committed to form an allocation subcommittee to fairly distribute
technical assistance funding to all SWCDs. Virginia also entered into contracts with all Bay
watershed PDCs to assist in the transition from planning to implementation.
Local Planning Goals
Key Strengths
Key strengths in the Phase III WIP include:
•	Virginia developed local planning goals that are measurable and below the major state-basin scale,
including goals for the unregulated urban, septic, and urban forestry sectors in each of the 15
regional PDCs and goals for unregulated agriculture and forestry in each of the SWCDs in the
Chesapeake Bay watershed.
•	Virginia specified basin-specific BMP goals for the agriculture, developed land, natural, and septic
sectors in each of its five major state-basins.
In its Phase III WIP, Virginia addressed the following potential enhancements that were suggested by
EPA in its draft Phase III WIP evaluation:
•	Virginia stated that it will not be tracking the local area planning goals and it will be using the CBP
partnership's modeling tools with as much geographic specificity as allowed and the verification
program to track progress at the local level.
Segment-shed Goals for the Tidal Jurisdictions

• Virginia's Phase III WIP now addresses the process for segment-shed targeting. However, in its
two-year milestones, Virginia should commit to using this process in prioritizing implementation.
BMP Verification
Jurisdictions agreed to follow CBP partnership-approved BMP verification protocols when developing
and implementing the Phase III WIPs. Because Virginia is proposing to increase BMP implementation
rates of some BMPs by 10-fold or more in the next seven years, the Commonwealth should ensure that
implementation at this higher rate can be tracked, verified, and reported within that period. 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 by another method established by the CBP partnership.
