15A NCAC 02B .0703 NUTRIENT OFFSET CREDIT TRADING
(a) PURPOSE. The purpose of this Rule is to establish standards and procedures applicable to providers for
approval of nutrient reduction projects and associated nutrient offset credits that will be transferred to persons or
entities subject to nutrient rules of this Subchapter. Nutrient offset credit is distinct from nutrient accounting for
direct compliance with individual nutrient strategy rules, which is not governed by this Rule. Nutrient accounting
includes joint compliance by multiple local governments as authorized in individual nutrient strategy rules. Nutrient
offset credits represent a compliance option to the extent allowed by nutrient rules of this Subchapter, including:
(1) the Neuse Nutrient Strategy as set forth in Rule .0710 of this Section;
(2) the Tar -Pamlico Nutrient Strategy as set forth in Rule .0730 of this Section;
(3) the Jordan Lake Nutrient Strategy as set forth in Rule .0262 of this Subchapter, including to the
extent that the requirements of this Rule related to the nutrient offset credits are incorporated by
the Jordan Lake rules; and
(4) the Falls Lake Nutrient Strategy as set forth in Rule .0275 of this Subchapter, including to the
extent that the requirements of this Rule related to the nutrient offset credits are incorporated by
the Falls Lake rules.
(b) GEOGRAPHIC RESTRICTIONS. Nutrient offset credits may be used to satisfy regulatory obligations only
when generated by a nutrient reduction project within an allowable geographic area identified in G.S. 143-214.26, as
designated by the U.S. Geological Survey, with the following additional restrictions:
(1) Nutrient offset credits may be used to satisfy regulatory obligations incurred in the upper Falls
watershed only if they were generated by a nutrient reduction project located within the upper
Falls watershed, as this geographic area is described in 15A NCAC 02B .0276.
(2) Nutrient offset credits may be used to satisfy regulatory obligations incurred in the lower Falls
watershed only if they were generated by a nutrient reduction project located within the Falls Lake
watershed, as these geographic areas are described in 15A NCAC 02B .0276.
(3) Nutrient offset credits may be used to satisfy regulatory obligations incurred in the Jordan Lake
watershed only if they were generated by a nutrient reduction project in the same subwatershed of
the Jordan Lake watershed, as these geographic areas are described in 15A NCAC 02B .0262.
(4) Nutrient offset credits may be used to satisfy regulatory obligations incurred in the Neuse 01 8-
digit cataloguing unit, as designated by the U.S. Geological Survey, outside of the Falls Lake
watershed only if they were generated by a nutrient reduction project located outside of the Falls
Lake watershed.
(5) Nutrient offset credits generated by nutrient reduction projects for compliance with an estuarine
nutrient strategy shall be generated in an area that is within or drains to:
(A) surface waters identified for restoration under the applicable nutrient -related TMDL or
nutrient strategy; or
(B) surface waters classified as SA, SB, or SC that fails to meet the chlorophyll -a water
quality standard in a subsequent integrated report.
(c) NUTRIENT OFFSET CREDIT APPROVAL STANDARD. Providers shall demonstrate that a nutrient
reduction project is designed, constructed, implemented, and sustained in a manner that, according to the best
available scientific evidence, studies, and principles, will generate the estimated nutrient load reduction for the
duration of time for which credits are approved. Nutrient offset credits shall be generated and transferred in
accordance with G.S. 143-214.26.
(d) QUANTIFYING NUTRIENT OFFSET CREDITS. The quantity of nutrient offset credits eligible to be
generated by a nutrient reduction project shall be determined according to the following provisions:
(1) Nutrient reduction credit sought on developed lands shall be calculated in relation to load
reductions achieved relative to the project site's current loading condition, as determined by the
provider and verified by the Division;
(2) Nutrient load reductions shall be site -specific estimates of decreases in annual mass load of
nitrogen or phosphorus to the nearest receiving surface water feature. Such estimates shall be
supported by the weight of evidence from available, current and applicable research, may involve
water quality modeling or engineering formulas and calculations, and shall reflect as closely as
possible project design specifications.
(3) Unless specifically excepted in Rule, reductions shall not include those already implemented to
satisfy other requirements under the same nutrient strategy; other local, State or federal
requirements; or those resulting from State or federal compensatory mitigation requirements.
Specifically, a nutrient reduction project shall not generate nutrient offset credits and buffer or
wetland mitigation credits in spatially overlapping areas. However, restored forest buffer areas
associated with stream mitigation projects may generate both stream and nutrient offset credits in
spatially overlapping areas within 50 feet from the top of the stream bank.
(4) Stream, buffer, or wetland mitigation credit that has not been used to satisfy a mitigation
requirement may be converted into nutrient offset credit if the credit -generating project or portion
thereof complies with this Rule.
(5) A nutrient reduction project may generate both nitrogen and phosphorus offset credits in the same
area.
(6) A nutrient reduction project may be designed to generate permanent nutrient offset credit or term
nutrient offset credit and shall specify which, or both, in the project plan. Permanent nutrient
reduction credits and term nutrient reduction credits shall be maintained separately, even if
associated with the same nutrient offset project.
(7) Permanent nutrient offset credits may be utilized for temporary compliance purposes. If so, for
each pound of annual term compliance credit received, 1/301 of one pound of permanent nutrient
offset credit shall be utilized and retired by removal from the applicable ledger.
(8) Nutrient offset credits that were approved prior to the adoption of this Rule may make application
to be reclassified. The Division shall approve the application associated with any nutrient offset
project to reclassify credits as permanent that meet the requirements for permanent credits at the
time of the application to be reclassified. Other nutrient offset credits that were approved prior to
the adoption of this Rule or that were conditionally approved pursuant to a mitigation banking
instrument or other agreement with DEQ prior to the adoption of this Rule, shall be considered
term credits and may be transferred between term and permanent ledgers at a ratio of 30 years of
term nutrient offset credit to one permanent nutrient offset credit.
(9) Term nutrient offset credits shall be associated with the calendar year or years in which the
associated nutrient load reductions are generated.
(e) PROJECT APPROVAL STANDARDS. Providers shall comply with the following requirements to request
approval from the Division to implement a nutrient reduction project for the purpose of generating nutrient offset
credits.
(1) NUTRIENT OFFSET BANKING INSTRUMENT. Providers seeking approval of a nutrient offset
bank shall submit their draft nutrient offset banking instrument to the Division prior to seeking
approval of project plans. A nutrient offset banking instrument shall provide legal and financial
assurances that a provider will implement, maintain, and sustain nutrient reduction projects as
proposed in subsequent project plans and associated nutrient reduction practice design
specifications.
(2) PROJECT PLAN REQUIREMENTS. Prior to initiating a nutrient reduction project, providers
shall submit a project plan proposal to the Division for review and approval that includes the
following elements:
(A) A site location and site boundaries of the proposed project.
(B) The geographic area eligible to be served by nutrient offset credits in accordance with
Paragraph (b) of this Rule or in compliance with in -lieu fee nutrient offset requirements
applicable at the time an in -lieu fee payment was accepted.
(C) Documentation of the conditions of the site at the time of the submittal of the project
plan.
(D) Documentation of the condition of the site during the baseline period of the applicable
nutrient strategy, unless excepted by Subparagraph (d)(1) of this Paragraph. The Division
may accept more recent documentation if it determines such documentation establishes
the probable loading condition of the site during the baseline period.
(E) A description of the proposed project that supports compliance with the standard in
Paragraph (c) of this Rule. Projects conforming to minimum design criteria for
stormwater control measures in 15A NCAC 02H .1050 through .1062 shall be deemed as
meeting this requirement. Design criteria for stormwater control measure variants and
additional nutrient reduction practices established in the Division's Catalog of Nutrient
Reduction Practices also meet this requirement.
(F) Nutrient credit calculations determined in conformance with Paragraph (d) of this Rule.
(G) Identification of the property owner and parties responsible for obtaining all permits and
other authorizations needed to:
(i) establish the proposed project;
(ii) construct and ensure initial performance of the project;
(iii) report on and successfully complete the project by completing all crediting
milestones;
(iv) hold and enforce all easement or other protection mechanisms; and
(v) ensure maintenance of the project for its credited duration.
(H) A description of how the project will be implemented, which shall include a timeline and
a commitment to provide an as -built report upon the full project construction or
installation.
(1) A description of how the project will be maintained and monitored after it has been
installed and for its duration.
(J) A description of how the project will be sustained for its credited life, including a
commitment to repair and renovate it as needed to maintain its performance, to keep
records of all such operation, maintenance, monitoring, repair and renovation, and to
notify the Division of any significant performance remediation needs and plans.
(K) Identification of federal or State grant funding contributing to project implementation.
(3) FINANCIAL ASSURANCES. Providers seeking approval of a nutrient offset bank shall provide
the financial assurance that a project plan will be constructed as proposed. The financial assurance
shall be in the form of a completion bond, credit insurance, letter of credit, escrow, or other
vehicle acceptable to the Division in accordance with this Subparagraph, payable to, or for the
benefit of, the Division, to ensure the involved property is secured in fee title or by easement and
that planting or construction, monitoring or maintenance are completed as necessary to meet the
requirements of the project plan.
(4) PROJECT PLAN APPROVAL. The Division shall approve the provider's project plan proposal
after verifying the provider's compliance with Subparagraphs (1), (2) and (3) of this Paragraph and
completing an onsite review to verify that preconstruction site conditions are suitable to generate
the credits proposed by the project plan. However, the Division may partially or fully waive these
requirements for term practices or projects if it determines that the burden of compliance is
disproportionate to the value of the credits being generated and alternative means are used to
satisfy the basic credit approval standard set forth in Paragraph (c) of this Rule.
(f) RELEASE AND ACCOUNTING FOR NUTRIENT OFFSET CREDITS. The Division shall release nutrient
offset credits from an approved project in the following manner:
(1) The Division shall release credits to providers upon confirmation that project -specific milestones
reflected in the project plan's credit release schedule have been met. Project -specific milestones
for permanent nutrient offset credits shall conform to the following requirements:
(A) Credits shall not be released until the property is secured in fee title or by easement and
financial assurance is posted for planting or construction of the project.
(B) No more than 50 percent of the credits shall be released for a project until financial
assurance is provided for monitoring and maintenance activities lasting until project
completion.
(C) No more than 80 percent of the credits shall be released for a project until the provider
complies with the requirements of Paragraph (g).
(2) Once credits are released for a nutrient offset bank and until bank closure, nutrient offset bank
providers shall provide a credit/debit ledger to the Division at intervals no less frequently than
quarterly.
(3) The Division shall not release any credits for a project if that project is financed in whole or in part
by State grant funding or federal grant funding.
(g) MAINTAINING PERMANENT NUTRIENT OFFSET CREDITS. All permanent nutrient offset projects shall
comply with the following requirements:
(1) A provider shall transfer responsibility for oversight of a completed permanent project to a
perpetual steward in accordance with this Paragraph and the approved project plan. A perpetual
steward may also transfer responsibility to another perpetual steward in accordance with the terms
of this Paragraph, subject to DWR approval. Perpetual stewards may not assume project
maintenance or restoration responsibilities.
(2) The provider shall create and transfer to the perpetual steward a non -wasting endowment or other
dedicated financial surety to provide for the oversight of the completed permanent project. The
endowment amount shall be proportionate to the duties accepted by the perpetual steward.
(3) For projects utilizing conservation easements, the provider shall acquire and then transfer a
conservation easement to a perpetual steward in accordance with 26 U.S.C. 170(h) and the
Conservation and Historic Preservation Agreements Act, G.S. 121, Article 4. The terms of the
conservation easement shall be consistent with a Division -approved template or be approved by
the Division as conforming to Paragraph (c) of this Rule. Non -governmental perpetual stewards
shall be accredited by the Land Trust Accreditation Commission or approved by the Division.
(4) For projects utilizing SCMs, they shall be placed in and protected by recorded drainage easements
with recorded access easements to the nearest public right-of-way for purposes of operation and
maintenance. These easements shall be granted in favor of the person or entity responsible for
operating and maintaining the structures, with a note as to the responsible person or entity.
Easements shall be of sufficient width for inspection and maintenance of the project.
The Division may temporarily or permanently invalidate permanent credits generated by an SCM
if it determines that the SCM has been impacted due to failure to comply with the terms of an
associated project plan, nutrient offset banking instrument, easement, maintenance agreement,
other protective agreement, or this Rule.
(5) Projects designed to restore a natural ecological community at the project site, which are
completed and then damaged by natural causes, may be passively restored exclusively through
natural ecological processes.
(h) RENEWING TERM NUTRIENT OFFSET CREDITS. Expiring term nutrient offset credits may be renewed by
the provider upon providing documentation to the Division that the project meets the credit approval standard
set forth in Paragraph (c) of this Rule for the duration of the renewal period.
(i) ADDITIONAL PROVISIONS REGARDING THE DIVISION OF MITIGATION SERVICES.
(1) DMS shall establish and revise nutrient offset rates as set out in 15A NCAC 02R .0602. Offset
payments accepted by DMS shall be placed into the Riparian Buffer Restoration Fund
administered by the Department pursuant to G.S. 143-214.21.
(2) On or before November 30 of each year, DMS shall provide an annual report to the Division
concerning the nutrient in -lieu fee program that includes a requirement ledger. The requirement
ledger shall include all nutrient offset credit requirements paid by 8-digit cataloguing unit or for
each geographic area identified in Paragraph (b) of this Rule, the date by which the requirement
shall be satisfied by a project, and the projects and credits that have been applied to all
requirements.
(3) Subject to the geographic restrictions in Paragraph (b) of this Rule, DMS may accept payments for
nutrient offset credits prior to initiating projects. After accepting payment, DMS shall construct
projects that, upon completion as described in the approved project plan, will generate nutrient
offset credits sufficient to fulfill all new requirements generated by these payments. Projects shall
be instituted before the end of the first full State fiscal year after DMS receives payment and
constructed before the end of the third full State fiscal year after DMS receives payment. DMS
may also acquire credits from another provider to apply toward its requirements.
(4) If DMS fails to meet deadlines associated with project institution or construction as specified in
Subparagraph (3) of this Paragraph, then DMS shall develop an action strategy to include in the
annual report specified in Subparagraph (2) of this Paragraph. Action strategies shall include all of
the following:
(A) a list of factors resulting in delays or deficiencies in procurement, project
implementation, or construction;
(B) specific actions and a timeline planned by DMS to satisfy outstanding credit requirements
such that a project will be instituted before the end of the first full state fiscal year after
the action strategy is submitted to the Division in the annual report and constructed
before the end of the third full state fiscal year after the action strategy is submitted to the
Division in the annual report, unless otherwise specified in the action strategy;
(C) the anticipated date by which all outstanding nutrient offset credit requirements will be
satisfied; and
(D) an evaluation of current progress in relation to any prior action strategies.
0) NUTRIENT OFFSET CREDIT TRANSACTIONS. Parties who seek to acquire nutrient offset credits under
rules of this Subchapter shall do so in compliance with those rules, the requirements of Paragraph (b) of this Rule,
G.S. 143-214.26, and the following:
(1) Offset payments made to DMS shall be contingent upon acceptance of the payment by DMS.
DMS shall consider its financial, temporal, and technical ability to satisfy the request to make its
determination.
(2) Where persons seek to satisfy regulatory obligations for more than one nutrient type, they shall
acquire nutrient reduction credits to address each type.
(3) Projects shall be approved and the associated offset credits released by the Division before they
may be utilized for NPDES wastewater permit compliance purposes.
(4) For offset credits used to meet NPDES wastewater discharge requirements, the applicant shall
provide 50 percent additional credits to address the uncertainty factor for using unmonitored
nonpoint source reductions to meet point source discharge limits. Application of this ratio is in
addition to other ratios that may be applied, including delivery or transport factors where
applicable. Exceptions to the application of this uncertainty factor are as follows:
(A) The uncertainty factor for wastewater dischargers in the Jordan Lake watershed shall
instead be determined in accordance with 15A NCAC 02B .0273(2)(d)(ii) until final
action is taken with respect to that rule's next readoption pursuant to G.S. 150B-21.3A,
S.L. 2016-94, and S.L. 2018-5.
(B) The uncertainty factor for wastewater dischargers in the Falls Lake watershed shall
instead be determined in accordance with 15A NCAC 02B .0282(2)(b)(i) until final
action is taken with respect to that rule's next readoption pursuant to G.S. 150B-21.3A,
S.L. 2016-94, and S.L. 2018-5.
(5) Delivery factors shall be applied to estimate nutrient reductions to an impaired water body subject
to a nutrient strategy if required under rules of this Subchapter for that strategy.
(6) Term credits may be utilized for compliance only during the year in which they are generated and
as described in Subparagraph (d)(2) of this Rule. They may not be cumulatively banked for future
years.
(k) DEVELOPER -RESPONSIBLE NUTRIENT OFFSET PROJECTS. A developer subject to new development
stormwater requirements of this Subchapter may satisfy its nutrient reduction obligations by generating its own
offsite credits. It may do so by establishing a nutrient offset bank and generating credits in accordance with this
Rule. Alternatively, the developer shall comply with all provisions of this Rule governing the generation of nutrient
offset credits by a provider with the following modifications:
(1) Instead of a credit release schedule, credit for the project may be assigned upon construction of the
project and submission to the Division of the as -built report as described in the project plan;
(2) Credit shall be assigned at a 50 percent rate based on the design specifications of the fully
completed project(s); and
(3) Liability for the generation of credits as described in the project plan remains with the developer
until the completion of all milestones associated with the project.
(1) NPDES WASTEWATER PERMITTEE-RESPONSIBLE NUTRIENT OFFSET PROJECTS. A locality,
authority, utility, or sanitation district operating a permitted wastewater facility subject to wastewater rules of this
Subchapter may generate nutrient offset credits by installing projects in accordance with this Rule. Any credits
generated may then be utilized for compliance purposes as if acquired from another provider.
