Q: In last month’s article I was asked if
there was any truth to the fact that there are sometimes mandatory BMPs which
must be followed.
A: The short answer to this question is
that there are no mandatory BMPs you are required to follow, unless you are
operating in jurisdictional wetlands. As mandated by Amendments to the Clean
Water Act, forest roads in jurisdictional wetlands including “waters of the
United States” must be constructed and maintained in accordance with the
following Best Management Practices to retain Section 404 permit exemption
status:
- Permanent roads, temporary
access roads, and skid trails in waters of the U.S. should be held to the
minimum feasible number, width, and total length consistent with the
purpose of specific silvicultural operations and local topographic and
climatic conditions.
- All roads, temporary or
permanent, should be located sufficiently far from streams or other water
bodies (except portions of such roads that must cross water bodies) to
minimize discharge of dredged or fill material into waters of the U.S.
- The road fill should be
bridged, culverted or otherwise designed to prevent the restriction of
expected flood flows.
- The fill should be
properly stabilized and maintained to prevent erosion during and following
construction.
- Discharges of dredged or
fill material into waters of the U.S. to construct a road fill should be
made in a manner that minimizes the encroachment of trucks, tractors,
bulldozers, or other heavy equipment within waters of the U.S. (including
adjacent wetlands) that lie outside the lateral boundaries of the fill
itself.
- In designing,
constructing, and maintaining roads, vegetative disturbance in the waters
of the U.S. should be kept to a minimum.
- The design, construction,
and maintenance of the road crossing should not disrupt the migration or
other movement of those species of aquatic life inhabiting the water body.
- Borrow material should be
taken from upland sources whenever feasible.
- The discharge should not
take, or jeopardize the continued existence of, a threatened or endangered
species as defined under the Endangered Species Act, or adversely modify
or destroy the critical habitat of such species.
- Discharges into breeding
and nesting areas for migratory waterfowl, spawning areas, and wetlands
should be avoided if practical alternatives exist.
- The discharge should not
be located in the proximity of a public water supply intake.
- The discharge should not
occur in areas of concentrated shellfish population.
- The discharge should not
occur in a component of the National Wild and Scenic River System.
- The discharge of material
should consist of suitable material free from toxic pollutants in toxic
amounts.
- All temporary fills should
be removed in their entirety and the area restored to its original
elevation.
