SUPPLEMENTARY INFORMATION:

Background

    NRCS plans to revise specific CPSs in the NHCP. This notice 
provides an overview of the planned changes and gives the public an 
opportunity to comment on the proposed revisions to these specific 
CPSs.
    NRCS State Conservationists who choose to adopt these CPSs in their 
States will incorporate them into their respective electronic Field 
Office Technical Guide. These CPSs may be used in conservation systems 
that treat highly erodible land (HEL) or on land determined to be 
wetland. Section 343 of the Federal Agriculture Improvement and Reform 
Act of 1996 (Pub. L. 104-127) states that revisions made after 
enactment of the law to NRCS State technical guides used to carry out 
HEL and wetland provisions must be made available for public review and 
comment.

    The following paragraphs highlight some of the proposed changes to 
each CPS:

[[Page 56103]]

    Access Road (Code 560): Minor wording revisions were made 
throughout the CPS to improve clarity. A legend was added to Figure 1. 
Usage information was removed from Table 1. Additional considerations 
were added to address air and water quality.
    Agrichemical Handling Facility (Code 309): This CPS was fully 
revised to clarify its complex requirements for preventing agrichemical 
spills and contamination. Notable updates include permitting multi-
owner facilities to implement the practice, introducing buoyancy 
control, revising liner material and liquid-tight structure 
requirements, and allowing the use of manufactured sumps. The revisions 
also provide more detailed facility descriptions to support broader 
applicability across diverse operational needs.
    Air Filtration and Scrubbing (Code 371): Clarifications and 
simplifications were made to the ``Definition'', ``Purpose'', 
``Criteria'', and ``Considerations'' sections. Additional detail was 
provided in the ``Plans and Specifications'' and ``Operation and 
Maintenance'' sections to further specify required elements and the 
types of documents necessary to record practice standard 
implementation. A generic reference to air pollution technology fact 
sheets was replaced with citations to specific fact sheets.
    Aquaculture Pond (Code 397): No major technical changes were made 
to this CPS. References to Critical Area Planting (Code 342) and 
Mulching (Code 484) were added. The ``Operation and Maintenance'' 
section was revised to better align with the Pond (Code 378) CPS.
    Bivalve Aquaculture Gear and Biofouling Control (Code 400): The 
``Conditions Where Practice Applies'' section was updated to include 
onshore gear storage, drying, and cleaning areas to align with the 
``Criteria'' section for exchanging fouled gear. The ``Plans and 
Specifications'' section now includes a requirement to clearly 
distinguish baseline management from planned improvements. The 
``Considerations'' section was expanded to address support for 
recovering lost gear after disasters. The ``References'' section was 
also updated.
    Brush Management (Code 314): This CPS was updated to incorporate 
active voice and modern guidance for managing woody and succulent plant 
species. The revisions clarify the practice purposes, strengthen 
ecological foundations, and emphasize alignment with ecological sites 
and plant communities. The ``Conditions Where Practice Applies'' 
section was refined to clarify where mechanical, chemical, and 
biological treatments apply, and requirements related to legal 
compliance, integrated planning, and long-term monitoring were 
reinforced. Wildlife considerations were enhanced to reduce potential 
adverse impacts. The ``Additional Criteria'' subsections now more 
effectively address ecological processes, adaptive management, and 
preventing reinvasion. The ``Considerations'' section was expanded to 
include guidance on mapping encroachment, coordination with grazing, 
forest, and wildlife plans, and recognizing biodiversity and habitat 
complexity. Updates to the ``Plans and Specifications'' and ``Operation 
and Maintenance'' sections provide clearer expectations for treatment 
methods, safety, herbicide use, monitoring, and retreatment. 
Collectively, these revisions improve alignment with current ecological 
science and NRCS guidance, enhance consistency across related practice 
standards, and support more effective, predictable, and longer-lasting 
treatment outcomes for landowners, partners, and conservation planners.
    Channel Bed Stabilization (Code 584): The ``Purpose'' section was 
updated to remove a statement unrelated to streambed stabilization. 
Additional minor wording changes were made throughout to improve 
clarity and readability.
    Contour Farming (Code 330): Minor edits were made to the 
``Considerations'' section. References to Contour Orchard and other 
Perennial Crops (Code 331) and Row Arrangement (Code 557) were added to 
clarify the ``Conditions Where Practice Applies'' section. One purpose 
was shortened to ``improve soil moisture retention.'' The ``General 
Criteria'' subsection was reorganized to align with steps for 
installation and contour marker installation was added. Additional 
contour layout suggestions were included in the ``Considerations'' 
section. Requirements in the ``Plans and Specifications'' section were 
clarified. The ``Operation and Maintenance'' section was reorganized to 
align with installation operations and maintenance requirements to 
ensure the practice meets its intended five-year lifespan.
    Critical Area Planting (Code 342): The definition of this CPS was 
updated to address concerns, including situations where normal planting 
methods may not be feasible. For consistency, standardized wording for 
plant material selection and use across all permanent planting 
practices was added. Engineering-related criteria were removed and are 
now referenced to Streambank and Shoreline Protection (Code 580). The 
``Conditions Where Practice Applies'' section was streamlined, and 
additional flexibility was provided for conservation practice 
installation and other construction sites to protect surface waters and 
source water.
    Cross Wind Ridges (Code 588): Revisions were made throughout to 
improve clarity. The ``Conditions Where Practice Applies'' section was 
simplified to include all cropland susceptible to wind erosion. 
Guidance in the ``Additional Criteria'' subsection was expanded to 
support evaluating plant productivity and health using wind erosion 
technology. The ``Plans and Specifications'' section was updated with 
clearer requirements.
    Dam (Code 402): The ``Cultural Resources'' subheading in the 
``General Criteria'' subsection was removed because it was considered 
redundant with the overall compliance statement in the first paragraph 
of that subsection. In the ``Additional Considerations for Visual 
Resource Design'' subsection, the second paragraph beginning with 
``Shape the embankment to blend with the natural topography...'', was 
removed because how-to procedures should not be included in a CPS. 
Minor wording changes were made throughout to improve clarity and 
readability.
    Dam, Diversion (Code 348): The first sentence in the ``Conditions 
Where Practice Applies'' section was removed because it did not 
describe where the CPS applies. Minor wording changes were made 
throughout to improve clarity and readability.
    Denitrifying Bioreactor (Code 605): Minor edits were made 
throughout to improve clarity, readability, and consistency. The 
``Definition'' section was updated to include microbial 
denitrification. Criteria under the ``Media Chamber'' subheading in the 
``General Criteria'' subsection were updated to address media mounding, 
soil-capped bioreactors, and allowable wood species.
    Dry Hydrant (Code 432): Minor wording revisions were made 
throughout to improve clarity and readability.
    Early Successional Habitat Development (Code 647): Updates include 
revisions to the title and lifespan to better align with planning 
tools; removal of the term ``management'' to address planning and 
contracting issues; consolidation of management and development 
activities; and improved alignment with certification and reimbursement 
processes. The revisions also shift the focus toward woody plant 
removal for habitat purposes.

[[Page 56104]]

    Fence (Code 382): Changes to this CPS primarily reflect the 
integration of virtual fence technology; updates to improve clarity 
through plain language and active voice; clarification of technical 
guidance; incorporation of contemporary ecological considerations; and 
updates to references. Virtual fence technology was incorporated 
through added content and edits across multiple sections of the CPS. 
The ``Purpose'' section was revised to state that the practice 
facilitates, rather than controls, resource management. The 
``Considerations'' section now identifies similar or related 
conservation practice standards, explains how these complementary 
practices differ, and describes how they may be applied together. 
Additional ecological considerations, based on new science related to 
wildlife interactions, were also added to the ``Considerations'' 
section.
    Forage Harvest Management (Code 511): Revisions to this CPS focus 
on restructuring content for clarity, applying active voice, and 
improving alignment with NHCP policy. The ``Definition'' section was 
updated to clarify that ``harvest'' does not always involve removal of 
forage. The ``Conditions Where Practice Applies'' section was broadened 
to include all lands where forage is mechanically manipulated. The 
``Purpose'' section was revised to consolidate soil compaction and 
aggregate stability into a single resource concern and to remove 
``optimize soil microbial life'' as an explicit purpose. The ``General 
Criteria'' subsection was reorganized to emphasize decision-making 
related to timing of forage cutting rather than harvest or storage 
methods, and content related to storage was relocated to the 
``Considerations'' section. The ``Additional Criteria'' subsections 
were refined to reduce redundancy, including updated guidance related 
to wildlife habitat, pest pressure, nutrient removal, and species 
composition. The ``Considerations'', ``Plans and Specifications'', 
``Operation and Maintenance'', and ``References'' sections were updated 
to improve formatting, enhance clarity, and incorporate current 
technical sources.
    Grade Stabilization Structure (Code 410): The ``Purpose'' section 
was revised to add ``prevent or reduce erosion and head cutting,'' 
ensuring the CPS explicitly addresses head cutting protection. The 
``Conditions Where Practice Applies'' section was updated to include 
``prevent or to reduce head cutting'' for consistency with the purpose 
statement. In the ``Small pond-sized Dams'' subheading under ``General 
Criteria,'' the initial sentence stating, ``For dams with an effective 
height of less than 15 feet and 10-year frequency, 24-hour storm runoff 
volume less than 10 acre-feet, the designer may use the requirements of 
NRCS CPS Water and Sediment Control Basin (Code 638)'', was removed.
    Grassed Waterway (Code 412): No major technical changes are 
proposed for this CPS. The ``Definition'' section was simplified for 
clarity. In the ``Criteria'' section, requirements related to livestock 
and vehicle crossings were expanded to safeguard proper design and 
installation. A consideration formerly associated with these crossings 
was removed from the ``Considerations'' section. Additionally, 
vegetative considerations within the ``Considerations'' section were 
reorganized and slightly revised to improve readability.
    Heavy Use Area Protection (Code 561): Minor wording changes were 
made to improve clarity in the ``Criteria'' section. Additions were 
made to the ``Considerations'' section to address air quality 
improvement. The ``References'' section was also updated.
    High Tunnel System (Code 325): NRCS is revising this CPS to improve 
clarity and ensure consistency with current technical guidance. The 
``Definition'' section was updated to more clearly distinguish high 
tunnel systems from other commercially available structures. Within the 
``General Criteria'' subsection, the required height for raised 
planting beds was increased to 18-inches to accommodate machinery-
formed natural soil beds and the use of frames to hold those beds in 
place. The ``Criteria'' section was reorganized to present structural 
requirements, siting considerations, and operational guidance in a more 
logical sequence. Language addressing salt buildup beneath high tunnels 
was added to both the ``Criteria'' and ``Considerations'' sections. 
Minor clarifications were made in the ``Plans and Specifications'' 
section. The ``Operation and Maintenance'' section was revised to align 
activities in a seasonal order and to make the connection to the 
``Criteria'' section more transparent.
    Irrigation Reservoir (Code 436): In the ``Conditions Where Practice 
Applies'' section, the second and third paragraphs were removed because 
they did not describe conditions under which this CPS applies. In the 
``Foundation, Embankment, and Spillways'' subsection of the ``General 
Criteria,'' the first sentence of the second paragraph--``Planting of 
critical areas at the completion of construction will help protect the 
structure and borrow areas and prevent erosion''--was removed to 
simplify the guidance. In the ``Considerations'' section, the fifth 
paragraph was relocated to the ``General Criteria'' subsection because 
it functions as a criterion rather than a consideration. In the final 
paragraph of the ``Considerations'' section, the last two sentences 
were removed for simplicity. Minor wording changes were made throughout 
to improve clarity and readability.
    Irrigation System, Microirrigation (Code 441): Minor edits were 
made throughout the CPS to improve clarity, readability, and 
consistency. The ``Conditions Where Practice Applies'' section was 
updated to include heavy-wall dripperline and mini- or micro- sprinkler 
system renovation. A new purpose--reducing energy use--was added to the 
``Purpose'' section. Additionally, new subsections titled ``Gravity-fed 
drip irrigation'' and ``Container irrigation'' were added to the 
``General Criteria Applicable to All Purposes'' section.
    Nutrient Management (Code 590): This CPS was revised to shift from 
plan-centered guidance to a strategy-centered, risk-assessment 
approach. Updated testing guidance strengthens the focus on nutrient 
use efficiency, drinking water and air quality protection, and emerging 
technologies, including precision agriculture and biological 
amendments.
    On-Farm Recharge (Code 641): This new CPS, developed from interim 
CPS Code 817, establishes criteria for applying surface water to 
cropland connected to unconfined aquifers to support groundwater 
recharge during periods when crops are dormant. No changes were made 
from the interim version.
    Pasture and Hay Planting (Code 512): This CPS was modernized, 
clarified, reorganized, and aligned with NRCS policy and updated 
resource concerns. The ``Purpose'' section was restructured to align 
with contemporary resource concerns and to clarify applicability 
boundaries between this practice and related CPSs. The ``Criteria'' 
section was updated to strengthen guidance on seed quality, planting 
rates, soil testing, species selection, planting depth, coated seed 
use, livestock exclusion, and overall establishment protocols. The 
``Considerations'' section was expanded to address wildlife needs, 
pollinator habitat, nurse crops, native species, invasive species 
avoidance, species diversity, and complementary conservation practices. 
In the ``Plans and Specifications'' section, more explicit 
documentation requirements

[[Page 56105]]

were added. The ``Operation and Maintenance'' section now includes 
expectations for monitoring environmental conditions and adjusting 
management as needed. The ``References'' section was updated to reflect 
current regulatory and scientific sources.
    Pest Management Conservation System (Code 595): In the ``Purpose'' 
section, two existing purposes were revised. New criteria were added to 
the ``Criteria'' section for USDA organic operations, and cultural, 
chemical, and biological suppression techniques were clarified. 
Additional requirements were included in the ``Criteria'' section 
related to ozone nonattainment areas. Language addressing VOCs, water 
quality, and soil health was added to both the ``Additional Criteria'' 
subsection and the ``Considerations'' section. The ``References'' 
section was updated to include current sources.
    Pond Sealing or Lining, Compacted Soil Treatment (Code 520): No 
major technical revisions were made to this CPS. All updates were made 
to clarify content, provide examples, improve readability, and maintain 
consistency across paragraphs. Two purposes were added to the 
``Purpose'' section, and new criteria were included in the ``Criteria'' 
section regarding compliance with applicable laws, safety, and existing 
impoundment requirements. The minimum liner thickness for clean-water 
storage impoundments was reduced in the ``Criteria'' section.
    Pond Sealing or Lining, Concrete (Code 522): The only major 
technical revision to this CPS was the addition of leak-detection 
requirements for installations in high-permeability soils. Other 
revisions throughout the CPS were made to clarify content, provide 
examples, improve readability, and maintain paragraph structure. Two 
purposes were added to the ``Purpose'' section, and additional criteria 
were included in the ``Criteria'' section to address compliance with 
applicable laws, safety, and existing impoundment requirements.
    Precision Land Forming and Smoothing (Code 462): The ``Definition'' 
section was revised to replace the term ``field'' with ``land'' to 
allow broader application of the practice. Language in the 
``Considerations'' section was revised to include measures that avoid 
and minimize impacts on wetlands and wildlife. References were added in 
the ``Considerations'' section for Site Assessment and Soil Testing for 
Contaminants Activity, Conservation Evaluation and Monitoring Activity 
(CEMA 207), and Soil and Source Testing for Nutrient Management (CEMA 
217) to address soil testing requirements when saline or toxic soils 
are uncovered. The ``References'' section was updated accordingly.
    Restoration of Rare and Declining Natural Communities (Code 643): 
Revisions to this CPS emphasize restoring physical and chemical site 
conditions, reducing overlap with planting and vegetation management 
practices, and incorporating innovative restoration techniques. New 
approaches referenced in the CPS include oyster and reef restoration, 
substrate replacement, low-tech restoration methods, and chemical 
restoration.
    Riparian Forest Buffer (Code 391): Revisions to this CPS provide 
clearer guidance and broader applicability by making establishment of 
riparian forest buffers more achievable, predictable, and impactful. 
Overlap with Drainage Water Management (Code 554) and Streambank and 
Shoreline Protection (Code 580) when those activities can be planned by 
other CPS as part of a comprehensive conservation plan was eliminated. 
The purpose of reducing sediment transport and pathogen transport was 
divided into two separate purposes to clarify additional criteria 
needed to implement each purpose. The wildlife purpose was expanded to 
improve the quality, quantity, or connectivity of terrestrial and 
aquatic habitat for wildlife, fish, and other organisms.
    Roof Runoff Structure (Code 558): This CPS was revised to increase 
flexibility in selecting materials for constructing roof runoff systems 
and to clarify criteria for discharging runoff into grassed waterways 
or diversions. Additional minor edits were made throughout to improve 
clarity and references were updated.
    Salinity and Sodic Soil Management (Code 610): Minor edits were 
made throughout the CPS to improve clarity and consistency. Additional 
criteria were added to the ``Criteria'' section addressing crop species 
selection based on salt tolerance, measures to reduce surface 
evaporation, and protections to prevent salt movement to seep outlets.
    Sediment Basin (Code 350): In the ``Conditions Where Practice 
Applies'' section, the final bullet limiting this practice to low-
hazard dams was removed. The ``Cultural Resources'' subheading in the 
``General Criteria'' subsection was removed because it was considered 
redundant with the overall compliance statement in the first paragraph 
of that subsection. Additional minor wording changes were made in the 
``General Criteria'' subsection to improve clarity and readability.
    Sinkhole Treatment (Code 527): This CPS was revised to improve 
clarity and refine technical guidance. Major revisions include refining 
the purpose of the CPS, limiting its application to in-situ native 
soils, and allowing assistance for clearing woody debris that obstructs 
normally draining sinkholes. The ``Criteria'' section was strengthened 
by providing clearer safety guidance and hydrologic evaluation 
requirements, and by removing the previous requirement for geology 
reports. Additional updates address ecological and cultural resources, 
modernize mapping guidance, require depth-to-bedrock information, 
enhance the ``Operation and Maintenance'' section, and update the 
''References'' section.
    Soil Carbon Amendment (Code 336): This CPS was updated by re-
ordering criteria, relocating text to appropriate sections, adding 
brief examples, and refining language to better convey the practice's 
intent. Revisions include clarification on when risk assessments are 
required; establishment of a new minimum carbon-to-nitrogen ratio of 
20:1 (excluding biochar); defined timelines for soil and amendment 
testing; biochar storage requirements; restrictions on application to 
frozen ground; removal of the exclusion on applying soil carbon 
amendments produced from crop or woody residues; and expanded 
operational flexibility for applying amendments on slopes and in high-
phosphorus risk areas.
    Sprinkler System (Code 442): Minor edits were made throughout the 
CPS to improve clarity, readability, and consistency. The ``Conditions 
Where Practice Applies'' section was updated to clarify the typical 
flow rate of sprinklers covered by this CPS. A new ``Safety'' 
subsection was added under ``General Criteria Applicable to All 
Purposes''. Additionally, a new subsection titled ``Variable Rate 
Irrigation'' was added to the ``Additional Criteria for Efficient and 
Uniform Application of Water on Irrigated Lands'' section.
    Stormwater Runoff Control (Code 570): No major technical changes 
were made to this CPS. In the ``Additional Criteria for Reduction of 
Water Quantity'' subsection, repeated text was removed because it 
already appears in the ``General Criteria'' subsection.
    Streambank and Shoreline Protection (Code 580): The ``General 
Criteria Applicable to All Purposes'' subsection was revised to remove 
potential causes of resource concern and to add criteria addressing 
geotechnical stability, ice forces, and scour. The ``Criteria'' section 
was updated to include requirements for geotechnical and hydraulic 
assessments.

[[Page 56106]]

Streambank classification criteria were clarified, and new criteria 
were added to address geotechnical stability, floodplain access, and a 
wide range of flow conditions. The ``Considerations'' section was 
expanded to add considerations emphasizing treatment variability and 
floodplain access. The ``Operation and Maintenance'' section was 
updated to include criteria addressing overbank flows and vegetation 
traffic. The ``References'' section was updated to include current and 
relevant technical resources.
    Structures for Wildlife (Code 649): Revisions to this CPS improve 
clarity in the definition, purpose, and applicability. Additions to the 
``Criteria'' section enhance structure use by target species and expand 
the range of acceptable structural options. New provisions allow for 
modification of existing human-made structures that negatively impact 
wildlife.
    Surface Drain, Field Ditch (Code 607): Revisions to this CPS remove 
redundant language, adopt active voice for improved clarity, and 
eliminate wording that could reclassify actively farmed or maintained 
drainage areas.
    Waste Facility Closure (Code 360): This CPS was revised to improve 
clarity and to better align its requirements with those of the Nutrient 
Management (Code 590) CPS.
    Waste Transfer (Code 634): This CPS was revised to add flexibility 
in pressure pipeline design by allowing the use of industry pipeline 
design standards. Additional edits throughout the standard improve 
clarity. The ``References'' section was updated to include the most 
current resources, including Federal Emergency Management Agency (FEMA) 
floodproofing guidance.
    Water Harvesting Catchment (Code 636): The ``Definition'' section 
was revised to emphasize the collection of precipitation runoff. The 
``Purpose'' section was updated to focus on water collection rather 
than distribution. The ``Conditions Where Practice Applies'' section 
was rewritten to include guzzlers. The ``Criteria'' section was updated 
to incorporate safety and structural requirements consistent with Roofs 
and Covers (Code 367), add measures to prevent debris entry, and 
address tank stability. The ``Considerations'' section was expanded to 
include mosquito and pest issues.
    Wetland Enhancement (Code 659): Revisions to this CPS streamline 
its scope to focus only on abiotic activities, such as earthmoving, 
that improve hydrologic wetland functions. The updates also reduce 
overlap with other CPS by ensuring that structural and vegetative 
practices are planned together, as appropriate, within a comprehensive 
conservation approach.
    Wildlife Habitat Planting (Code 420): Revisions to this CPS provide 
clearer guidance to directly support farmers. Formatting updates align 
the CPS with recent revisions made to other biology discipline CPS. The 
changes reduce overlap between vegetative planting practices and 
vegetation management practices when management should be addressed by 
another practice standard within a comprehensive conservation plan. 
Technical criteria were improved to ensure CPSs intent and requirements 
are met. The ``References'' section was updated to include the most 
current resources.
    Windbreak-Shelterbelt Establishment and Renovation (Code 380): The 
title of this CPS was shortened because the definition already 
clarifies that the practice is used to establish, enhance, or restore 
windbreaks, and is also known as shelterbelt. The carbon storage 
purpose was moved to the ``Considerations'' section because it 
represents a secondary benefit. The energy use purpose was also moved 
to the ``Considerations'' section, as practice standard purposes must 
be achievable within the practice lifespan, and trees and shrubs 
generally require more than the fifteen-year practice lifespan to reach 
heights that shade structures and reduce energy use. Noise reduction 
and visual screen considerations were removed because they do not 
address a resource concern. Updated guidance reflecting current 
technology was added to support conservation planners in practice 
design and implementation.
