Section 1
General
1.1
Preamble:
Agriculture has been identified as a major contributor of non-point
source pollution to surface waters of Vermont. For example, the Lake
Champlain Total Maximum Daily Load (TMDL), as modeled by the
Environmental Protection Agency, estimates that nutrient losses from
agricultural activities represent 29% of the total phosphorous load
to the Lake Champlain basin and over 40% of Vermont's contribution to
the phosphorous load to the basin. Agriculture contributes non-point
source pollution to surface and groundwater from multiple sources,
including cropland erosion, farmstead management, crop storage, and
manure storage and application. While contributions of non-point
source pollution from agriculture may vary from watershed to
watershed, the overall impact to water quality from agricultural
lands, when not managed well, is significant.
The Vermont legislature first directed the Agency of
Agriculture, Food and Markets to develop a comprehensive Agricultural
Non-Point Source Pollution Reduction Program in 1992. The Accepted
Agricultural Practices Rules (AAPs), which regulate farming
activities in order to protect water quality, became effective in
1995 and were revised in 2006.
As a result of Act 64--the Vermont Clean Water
Act--the Agency of Agriculture was tasked with updating the AAPs to
further reduce the impact of agricultural activities to water quality
across the State. The Required Agricultural Practices Rules (RAPs)
are an updated version of the AAPs, re-written to a higher level of
performance.
Act 64, which was signed into law by the Governor in
June 2015, amended and enacted multiple requirements related to water
quality in the State. The act required the Agency of Agriculture to
amend several provisions of the AAPs in order to improve water
quality in Vermont. The first change was to rename the Accepted
Agricultural Practices Rules the Required Agricultural Practices
Rules. The RAPs are standards to which all types of farms must be
managed. Act 64 further required the Agency of Agriculture to:
-- Establish requirements for a Small Farm
Certification Program;
-- Establish nutrient, manure, and waste storage
standards;
-- Make recommendations for soil health;
-- Establish requirements for vegetated buffer
zones;
-- Establish requirements for livestock exclusion
from surface water;
-- Establish nutrient management planning standards;
and
-- Establish standards for soil conservation such as
cover cropping
The standards and rules that follow are intended to
improve the quality of all of Vermont's waters by reducing and
eliminating cropland erosion, sediment losses, and nutrient losses
through improved farm management techniques, technical and compliance
assistance, and, where appropriate, enforcement. This rule strives to
balance the complexity, variability, and requirements of farm
management with the need to improve that management in order to meet
the State's goals in improving and protecting water quality.
Soil quality and soil health are critical elements of
an overall agricultural non-point source pollution reduction program.
Agricultural soils are recognized as a critical resource for the
overall prosperity of Vermont's agricultural community and for the
public at large. Efforts to build soil organic matter, increase
biological activity, and reduce compaction, including reduced
tillage, use of composts, establishing crop rotations, cover
cropping, and the elimination of annual cropping on highly vulnerable
lands, will be essential to the success of programs whose goal is to
improve Vermont's water quality. The Vermont Agency of Agriculture,
Food and Markets supports and endorses all practices that lead to the
goal of healthy soils and productive agricultural
lands.
1.2
Enabling
Legislation: As defined in
6 V.S.A.
§§
4810 and
4810a,
the Required Agricultural Practices (RAPs) shall be management
standards to be followed by all persons engaged in farming in this
State. These standards shall address activities which have a
potential for causing agricultural pollutants to enter the
groundwater and waters of the State, including dairy and other
livestock operations, all forms of crop and nursery operations and
on-farm or agricultural fairground registered pursuant to
20 V.S.A. §
3902, and livestock and poultry
slaughter and processing activities. The RAPs shall include, as well
as promote and encourage, practices for farmers in preventing
agricultural pollutants from entering the groundwater and waters of
the State when engaged in animal waste management and disposal, soil
amendment applications, plant fertilization, and pest and weed
control. Persons engaged in farming who are in compliance with these
practices shall be presumed to not have a discharge of agricultural
pollutants to waters of the State. The RAPs shall be designed to
protect water quality and shall be practical and cost-effective to
implement, as determined by the Secretary.
1.3
Purpose:
The RAPs are farm and land management practices that will control and
reduce agricultural nonpoint source pollution and subsequent nutrient
losses from farm fields and production areas to surface and ground
waters of the State or across property boundaries. The RAPs also
establish minimum construction and siting requirements for farm
structures in floodplains, floodways, river corridors, and flood
hazard areas.
1.4
Authority:
6 V.S.A. Chapter 215 (Agricultural Water Quality), including
§§ 4810, 4810a, and 4811, and Act 64 of the Vermont General
Assembly (2015 session).
1.5
Enforcement:
Violations of this rule are subject to enforcement by the Secretary
of the Vermont Agency of Agriculture, Food and Markets and the
Attorney General under the provisions of
6 V.S.A. §§
4991 -
4996
and additional remedies available to the State under other applicable
Vermont law.
1.6
Further
considerations under the RAPs:
6 V.S.A. §
4810a(b) requires
that on or before January 15, 2018, the Secretary of Agriculture,
Food and Markets shall amend by rule the Required Agricultural
Practices in order to include requirements for reducing nutrient
contribution to waters of the State from subsurface tile drainage. As
part of the rule amendment process, the Secretary may also evaluate
the current status of effectiveness of the Required Agricultural
Practices, the implementation of additional best management
practices, and the current water quality condition of waters of the
State. The Secretary may consider additional changes to the Required
Agricultural Practices, as appropriate, to meet the water quality
goals of the State.

shall not be applied within the buffer zone.
(g) Manure or other agricultural
wastes shall not be mechanically applied within 100 feet of a private
water supply or 200 feet of a public water supply. This prohibition
shall not apply to private water supplies that have been established
inconsistent with the Department of Environmental Conservation Water
Supply Rules existing at the time that the water supply was
established.

when frozen or snow-covered soils prevent effective incorporation at
the time of application, require manure to be applied according to a
nutrient management plan, establish the maximum amounts of manure
that may be applied per acre during any one application, and
establish required manure spreading setbacks from surface water,
water supplies, and other water conveyances. Seasonal exemptions to
the winter spreading ban may be renewed annually upon request and
submission of winter spreading records of application.

Buffer Zones:
Manure and Agricultural Wastes Application
Setbacks A vegetative buffer zone of perennial
vegetation shall be maintained between croplands and the top of the
bank of adjoining surface waters and ditches consistent with the
criteria in (a) through (i) below:
(a) Adjacent surface waters shall
be buffered from croplands by 25 feet of perennial
vegetation.
(b) Ditches
shall be buffered from croplands by 10 feet of perennial vegetation
unless determined to potentially transport significant waste or
nutrients to surface water consistent with the USDA 590 standard
nutrient management requirements.
(c) Surface inlets or inlets of
open drains shall be buffered from croplands by 25 feet of perennial
vegetation.
(d)
Mechanical application of manure or other agricultural wastes is
prohibited within perennially vegetated buffer zones. Grazing of
livestock consistent with the provisions of Section
7
of this rule is permitted.
(e) The use of fertilizer or
compost for the establishment and maintenance of a required
vegetative buffer zone is allowed consistent with nutrient management
plan requirements, soil analysis, and agronomic recommendations for
the buffer zone.
(f)
Tillage within the perennially vegetated buffer zone is prohibited
other than for the establishment and maintenance of the buffer
zone.
(g) Harvesting a
vegetative buffer zone as a perennial crop is allowed.
(h) Spoils from agricultural ditch
maintenance shall not be stored in the buffer zone or in such a
manner as to discharge to surface water.

6.05(f), may be considered upon request on a site-specific basis
according to standards approved by the Secretary, but in no case
shall a buffer zone be less than 10 feet in width. Site-specific
buffer zones may be approved based on field characteristics such as a
determination that a conveyance has the potential to transport
significant wastes or nutrients to surface water, field contours,
soil types, slopes, proximity to water, nutrient management plan
requirements, and other relevant characteristics when the Secretary
determines that the proposed site-specific buffer zones are
adequately protective of surface waters.

in their natural state except as allowed by State statute including,
but not limited to,
10 V.S.A. §
1021, and the standards established
for the pasturing of livestock consistent with Section
7
of this rule.
(b)
Stabilization of farm field banks of surface waters, when allowed
under Section 6.10(a) of this-- rule, shall be constructed in
accordance with the USDA NRCS standards and specifications or other
standards approved by the ANR and the Agency that are consistent with
policies adopted by the Secretary of Natural Resources to reduce
fluvial erosion hazards.
Section 8 Ground Water
Quality and Groundwater Quality Investigations
(a) Farm operations shall be
conducted so that the concentration of wastes in groundwater
originating from agricultural operations do not reach or exceed the
primary or secondary groundwater quality enforcement standards
identified by Appendix One of the Groundwater Protection Rule and
Strategy in accordance with 10 V.S.A. Chapter 48 (Groundwater
Protection).
(b) Farm
operations shall be conducted with the goal of reducing the
concentration of wastes in groundwater to the preventive action
levels (PALs) of the primary or secondary groundwater quality
standards identified by Appendix One of the Groundwater Protection
Rule and Strategy when monitoring indicates the presence of these
wastes in groundwater that exceed the enforcement standard.
(c) The Secretary may conduct
groundwater quality monitoring to assess the impact of agricultural
practices and farm operations on the quality of drinking water and
groundwater. The Secretary may conduct groundwater sampling at sites:
(1) selected by the Secretary where
water supply owners or tenants have volunteered or agreed to
participate in the sampling program;
(2) upon the request of a water
supply owner or tenant;
(3) selected by the Secretary based
on the results of other sampling data or the existence of vulnerable
site characteristics; or
(4) with activities or operations
permitted, certified, or regulated by the Secretary.
(d) The Secretary shall
conduct a groundwater investigation where the Secretary has received
a complaint from a water supply owner in the vicinity of a farm that
the farm or its agricultural practices has contaminated the drinking
water or groundwater of the water supply owner.
(e) The Secretary shall conduct a
groundwater investigation where sampling indicates that drinking
water or groundwater contains detectable concentrations of
agricultural wastes.
(f)
The Secretary shall provide:
(1)
written notification of testing results to each individual water
supply owner and tenant, if known, that participates in the sampling
program.
(2) property
owners in the vicinity of farm operations and agricultural lands with
the test results for each water supply owned by them that is sampled
by the Secretary.
(3)
farm operations with the test results for water supplies owned by the
farm operation and, upon request, for water supplies adjacent to or
impacted by the crop land or facilities managed by the farm
operation.
(g)
In order to identify and remediate sources of drinking water and
groundwater contamination, the Secretary, without limitation, may:
(1) conduct site visits to
interview property owners and farm operators, gain an understanding
of the physical characteristics of the landscape and locate
additional sites for water quality sampling;
(2) communicate with farm operators
and adjacent property owners to identify practices and activities
that are potential sources of contamination; (3) conduct additional
sampling to confirm the detection of contaminants and to determine
the extent and scope of contamination at the site;
(4) require corrective actions such
as changes in activities, management practices, cropping patterns, or
structural revisions designed to reduce the contamination from
current activities and prevent contamination from future
activities;
(5) conduct
follow up water quality sampling to determine the effectiveness of
changes made or corrective actions taken;
(6) seek additional investigative
or consultation resources to evaluate and characterize sites to
determine vulnerability to drinking water and groundwater
contamination; and
(7)
review testing results and site evaluations to determine if changes
in water quality data are the result of changes in activities or
natural site conditions.
(h) The Secretary may require the
owner or operator of a waste storage facility to modify the facility
to meet the USDA NRCS or an equivalent standard for the facility or
to implement additional management measures if the facility poses a
threat to human health or the environment as established by an
exceedance of the State's Groundwater Quality Standards.
(i) For the purpose of assessing
whether a waste storage facility is violating the State's Groundwater
Quality Standards, the Secretary shall pay for the initial costs to
conduct groundwater monitoring. When the Secretary has made a
determination that a waste storage facility is violating the State's
Groundwater Quality Standards, the Secretary shall provide
notification to the Department of Health and the Agency of Natural
Resources. This notification shall occur within 21 days and include
the location of the facility and the name of the owner or operator.
When the Secretary makes a determination that a waste storage
facility no longer poses a threat to human health or the environment,
the Secretary shall provide notification of the revised determination
to the Department of Health and the ANR.
