SUPPLEMENTARY INFORMATION:
Background
NRCS is planning to revise the conservation practice standards in
the National Handbook of Conservation Practices (NHCP). This notice
provides an overview of the planned changes and gives the public an
opportunity to provide comments on the specific conservation practice
standards that NRCS is changing.
NRCS State Conservationists who choose to adopt these practices in
their States will incorporate these practices into the respective
electronic Field Office Technical Guide. These practices may be used in
conservation systems that treat highly erodible land (HEL) or on land
determined to be a wetland. Section 343 of the Federal Agriculture
Improvement and Reform Act of 1996 requires NRCS to make available for
public review and comment all proposed revisions to conservation
practice standards used to carry out HEL and wetland provisions of the
law.
Revisions to the National Handbook of Conservation Practices
The amount of the proposed changes varies considerably for each of
the conservation practice standards addressed in this notice. To fully
understand the proposed changes, individuals are encouraged to compare
these changes with each standard's current version, which can be found
at: http://www.nrcs.usda.gov/wps/portal/nrcs/detailfull/national/technical/cp/ncps/?cid=nrcs143_026849.
NRCS is requesting comments on the following conservation practice
standards:
Agrichemical Handling Facility (Code 309);
Air Filtration and Scrubbing (Code 371);
Channel Bed Stabilization (Code 584);
Contour Orchard and Other Perennial Crops (Code 331);
Cover Crop (Code 340);
Dry Hydrant (Code 432);
Dust Management for Pen Surfaces (Code 375);
Energy Efficient Agricultural Operation (Code 374);

Waste Transfer (Code 634);
Wastewater Treatment--Milk House (Code 627);
Wetland Creation (Code 658); and
Windbreak/Shelterbelt Establishment and Renovation (Code
380).
The following are highlights of some of the proposed changes to
each standard:
Agrichemical Handling Facility (Code 309): Minor revisions were
made for improved organization and for clarity. Some flexible membrane
liner thicknesses were changed. The minimum storage volume of the
Agrichemical Handling Facility was changed to 1.1 times the volume of
largest storage container within the containment area, plus the
displacement volume that is occupied by all the other tanks within and
below the height of the containment wall or dike.
Air Filtration and Scrubbing (Code 371): Formatting and writing
style were updated to meet current agency requirements. Minor revisions
were made for clarity and readability purposes and to update citations
for existing references. Major changes were made to the Plans and
Specifications to identify needed information and to remove
requirements of supplying supporting documentation with plans and
specifications.
Channel Bed Stabilization (Code 584): Minor changes were made,
mostly requiring more specific channel and sedimentation information in
the Plans and Specifications section.
Contour Orchard and Other Perennial Crops (Code 331): The standard
was edited for clarity. Minor revisions were made for clarity and
readability purposes. Definition was edited for
[[Page 13523]]
improved explanation. Paragraphs in General Criteria and Considerations
were edited for improved understanding.
Cover Crop (Code 340): Minor wording changes were made throughout
for clarification. In the Purpose section, specific soil health
resource concerns were added as two purpose statements on soil organic
matter quantity and aggregate instability, soil organic matter quality,
and habitat for soil organisms. In the General Criteria section, the
reference to when cover crops are established has been better defined.
One change added ``no mechanically harvest of cover crops'' to clarify
that cover crops can be grazed but not harvested otherwise. In the
Additional Criteria section, a change established criteria for grazing
cover crops to improve organic matter.
Dry Hydrant (Code 432): The revised standard expands the purpose of
dry hydrant to include providing access of available water for
additional purposes including livestock water, small acreage
irrigation, wetland management, and other purposes where water is
needed in limited quantities on a periodic basis in addition to the
purpose of providing access to an available water source for fire
suppression. The revised standard is intended to be more flexible
regarding the use of the standard and encouraging landowners to install
dry hydrants to meet needs in addition to fire suppression. Criteria
were divided to separately address fire suppression and other purposes.
Criteria were revised to be more general.
Dust Management for Pen Surfaces (Code 375): The name of this
standard has been changed from ``Dust Control from Animal Activity on
Open Lot Surfaces'' to ``Dust Management for Pen Surfaces'' to reflect
that it is now entirely a management standard and to simplify the name.
Formatting and writing style were updated to meet current agency
requirements. Specific criteria, considerations, and references to
water application via solid set sprinkler systems were removed from the
standard because it is now covered in Sprinkler System (Code 442).
Specific criteria related to increased stocking density to supply
additional moisture to the pen surface for reducing dust potential were
added. New references were added, and minor revisions were made for
clarity and readability purposes and to update citations for existing
references.
Energy Efficient Agricultural Operation (Code 374): The standard
has been revised extensively. The name has been changed from
``Farmstead Energy Improvement'' to ``Energy Efficient Agricultural
Operation'' to reflect the energy efficiency purpose. The standard has
been rewritten to focus on the energy efficiency criteria, fire and
electrical safety, flexibility, and manufacturer's requirements. The
requirement for an ASABE S612 Type 2 energy audit has been revised to
allow other assessment methods. Criteria was added to support
Prescriptive Upgrades to simplify and streamline implementation of some
instances of the practice. Criteria was added for heat and air transfer
systems and equipment.
Fence (Code 382): Formatting and writing style were updated to meet
current agency requirements. Minor revisions were made for clarity and
readability purposes. References were updated based on literature
review.
Grazing Land Mechanical Treatment (Code 548): The definition was
changed by removing the equipment listed. Added equipment list to
criteria separated by soil or plant disturbances. Reduced safe slope
work from 30 to 20 percent.
Land Reclamation, Abandoned Mined Land (Code 543): The criteria in
Land Reclamation, Currently Mined Land (Code 544) and Land Reclamation,
Toxic Discharge Control (Code 455), were added to criteria for Land
Reclamation, Abandoned Mined Land to put all of the related technical
criteria into one standard. The definition, purpose, and conditions
where the practice applies were updated to reflect the intent of the
practice. The criteria were updated to include the current
environmental and personal safety laws and requirements. Plans and
Specifications were updated to include the required level of detail.
On-Farm Secondary Containment Facility (Code 319): Formatting and
writing style were updated to meet current agency requirements. The
redundant purpose was removed since both were to protect water quality.
Technical requirements were added or revised, as needed, to be
consistent with other referenced codes within the standard.
Precision Land Forming and Smoothing (Code 462): The standard has
been combined with CPS 466-Land Smoothing since both standards are
similar in practice. Minor revisions were made. Clarity was added
regarding grading plan and soil health.
Recreation Land Improvement and Protection (Code 566): CPS 566,
originally titled Recreation Land Grading and Shaping, is being
combined with CPS 562, Recreation Area Improvement, and renamed CPS
566, Recreation Land Improvement and Protection. Combining the two
standards into a single standard makes sense logically and allows for
eliminating one of the standards. The new standard retains the number
Code 566, and titled, Recreation Land Improvement and Protection to
better reflect the elements of the two standards being combined. CPS
562 will be archived. CPS 566 is not a standard likely to be used under
NRCS administered programs, such as EQIP, but is a useful standard for
Watersheds Protection and Flood Prevention Act (Pub. L. 83-566) work in
those locations with the potential for development of recreational
facilities.
Roof Runoff Structure (Code 558): One purpose was rewritten to
remove references to foundation protection since that is not an
established resource concern and now just addresses soil erosion. Minor
wording changes were made to the Criteria section for clarity and
specificity. Changes were made to the Additional Criteria section to
Capture Water for Other Uses to address water quality for reuse of
captured water and criteria modified for storage of the captured water.
Sinkhole Treatment (Code 527): The name was changed from Karst
Sinkhole Treatment to Sinkhole Treatment. Safety hazard was addressed
as well as minor wording changes to improve clarity.
Sprinkler System (Code 442): Formatting and writing style were
updated to meet current agency requirements. Minor revisions were made
for clarity and readability purposes. Updated Tables to meet current
industry standards. Modified the Land Slope section to allow for pivot
systems that may not meet the slope requirement but meet the run-off
and application rate requirements. Added a section for Mobile Drip
Irrigation (MDI). MDI is a type of irrigation that is partially
sprinkler and partially drip type irrigation and it was decided that
MDI criteria is more applicable to the standard.
Stream Crossing (Code 578): This standard has a few major changes
including that it increases siting flexibility, and the addition of
vented fords as an alternative where frequent overtopping is expected.
Waste Separation Facility (Code 632): Safety was moved to the
beginning of the General Criteria section to emphasize the need for
safety on all separation technologies. Wording was added to address
location of the facilities and the requirement to manage the 25-year,
24-hour storm event. The sections on Separator selection and Separation
efficiency were revised to reference NRCS guidance document National
Engineering Handbook (NEH),
[[Page 13524]]
Part 637, Chapter 4. Direction was added to the Storage or Treatment of
Separated Solids section to design storage facilities for separated
solids in accordance with the appropriate NRCS standard. A
consideration on the biosecurity of separation facilities was added.
Waste Transfer (Code 634): Formatting and writing style were
updated to meet current agency requirements. Minor revisions were made
for clarity and readability purposes. The structural design
requirements were updated to align with changes made to the National
Engineering Manual. The criteria for reception pit size, pipe clean-
outs and pipeline velocity were revised.
Wastewater Treatment--Milk House (Code 627): Added a new
conservation practice standard developed to better address the
technical complexities of treating greywater from cleaning the milking
equipment. The practice standard is based on several university
extension publications referenced in the standard and NRCS field
experience.
Wetland Creation (Code 658): The standard revision removed soils as
a purpose and added an additional purpose of creating a native plant
community adapted to growth and regeneration in anerobic conditions.
Establishment of hydric soil was removed as a purpose because anaerobic
soil conditions is an outcome, not a purpose. The new practice standard
Wildlife Habitat Planting (Code 420) is listed as appropriate for
vegetative establishment when wildlife habitat is a purpose. This
allows the use of Wetland Creation (Code 658) when the purpose is to
establish a unique plant community without targeting a single species
of wildlife or guild.
Windbreak/Shelterbelt Establishment and Renovation (Code 380): Two
practice standards were combined, and Code 380 now includes windbreak
renovation as well as establishment. The definition, purpose,
conditions where practice applies, and considerations sections were
updated. Criteria sections were added to address renovation; several
other sections were moved to the Considerations section. The Plans and
Specifications section were expanded to align with conservation plan
requirements, and operations and maintenance sections were expanded to
clarify requirements. References were added.
