Virginia's Erosion and Sediment Control Program
Erosion and Sediment
Control on Construction Sites
Soil erosion is the process of detachment and transportation of soil
materials by water, wind, ice and gravity. While "geologic"
erosion naturally produces about 30 percent of the total sediment in
the United States, "accelerated" soil erosion from man's use
of land accounts for the remaining 70 percent. Surface mining, forestry,
agriculture and construction are the major activities that cause accelerated
erosion. Although construction by volume does not cause most sediment
pollution, it is the most evident and damaging because of the rate at
which it occurs. Erosion associated with construction activities can
be 200 times greater than that from cropland and 2,000 times greater
than that naturally occurring in woodlands.
When natural landscape is converted to accommodate houses, subdivisions,
shopping centers, and roads in rural areas, or development and redevelopment
within cities and towns, these land use conversions are collectively
referred to as urbanization. Water-generated accelerated erosion
is unquestionably the most severe erosion in areas undergoing urbanization.
Erosion problems associated with construction activities include water
pollution, flooding, stream channel damage, decreased groundwater storage,
slope failures, damage to adjacent and/or downstream properties, and
the time and costs associated with addressing these issues. Successful
minimization of these impacts can be achieved by implementing erosion
and sediment control (ESC) measures on construction sites to prevent
soil movement/loss in the first place, enhance project aesthetics, reduce
complaints, and most importantly, eliminate appreciable damage to off-site
receiving channels, property and natural resources.
Virginia was among the first states to specifically address ESC from
construction sites by establishing Virginia's ESC Program nearly 30
years ago.
Program Overview
Erosion and Sediment Control Law and Regulations
DCR implements the state ESC Program according to the Virginia Erosion
and Sediment Control Law, Regulations, and Certification Regulations
(VESCL&R). The law is codified at Title 10.1, Chapter 5, Article
4 of the Code of Virginia, regulations are found at Section 4VAC30-50,
and certification regulations are found at Section 4VAC50-50 of the
Virginia Administrative Code. The ESC Program's goal is to control soil
erosion, sedimentation, and nonagricultural runoff from regulated "land-disturbing
activities" to prevent degradation of property and natural resources.
The regulations specify "Minimum Standards," which include
criteria, techniques and policies, that must be followed on all regulated
activities. These statutes delineate the rights and responsibilities
of governments that administer an ESC program and those of property
owners who must comply.
Cooperative Implementation
A network of local government-operated ESC programs regulate most private
projects involving a land-disturbing activity, while DCR's ESC Program
staff oversees state and federal activities. The requirement for submission,
review, approval, and proper execution of ESC "plans," or
"agreements in lieu of plans," which identify all onsite ESC
measures and policies, form the basis for program implementation. While
property owners are ultimately responsible for ESC plan approval and
implementation, responsibility for ensuring compliance extends to the
developer, contractor, consultant and Virginia's citizenry at-large.
The successful execution of ESC programs affects a variety of interests,
from anyone who owns, rents or develops property to those who reside
or recreate on lands or waters adjacent to or downstream from land-disturbing
activities.
Protection for All Citizens
The state ESC Program aims to ensure fairness so less conscientious
developers do not gain an economic advantage. It also advocates technically
sound and economical control of nonpoint source pollution. The program
emphasizes that proactive implementation of ESC not only conserves
and protects resources but also is more practical and cost-effective
in the long-term when compared to reactionary approaches that
may lead to costly delays or expensive remediation of damages from inadequate
ESC implementation. Simply put, the standards and policies promoted
by the ESC Program include quality construction, engineering, and administrative
practices that endeavor to provide equal protection for all properties
and resources across the commonwealth.
Regulated Land-Disturbing
Activities
The ESC Program regulates only construction activities that constitute
land-disturbing activities under the VESCL&R. To that end, it is
essential that regulators and the regulated community fully understand
this definition.
A land-disturbing activity is "any land change on private or public
land that may result in soil erosion from water or wind and the movement
of sediments into state waters or onto lands in the commonwealth, including,
but not limited to, clearing, grading, excavating, transporting, and
filling of land." This definition includes land-disturbing activities
equal to or exceeding 10,000 square feet in area; however, the following
13 activities are specifically exempt from the definition:
- Disturbed land areas of less
than 10,000 square feet in size; however, a local ESC program may
reduce this exception to a smaller area of disturbed land or qualify
the conditions under which this exception shall apply;
- Minor land-disturbing activities
and individual home landscaping, repairs and maintenance work;
- Individual service connections;
- Installation, maintenance or
repair of underground public utility lines when such activity is confined
to an existing hard surfaced road, street or sidewalk;
- Septic tank lines or drainage
fields unless included in an overall plan for land-disturbing activity
relating to construction of the building to be served by the septic
tank system;
- Surface or deep mining;
- Exploration or drilling for
oil and gas including the well site, roads, feeder lines and off-site
disposal areas;
- Tilling, planting or harvesting
of agricultural, horticultural or forest crops, or livestock feedlot
operations; including a specific list of engineering operations;
- Repair or rebuilding of the
tracks, right-of-way, bridges, communication facilities and other
related structures, and facilities of a railroad company;
- Agricultural engineering operations
including but not limited to the construction of terraces, terrace
outlets, check dams, desilting basins, dikes, ponds not required to
comply with the provisions of the Virginia Dam Safety Act, ditches,
strip-cropping, lister furrowing, contour cultivating, contour furrowing,
land drainage and land irrigation;
- Installation of fence, sign,
telephone, electric, or other kinds of posts or poles;
- Shore erosion control projects
on tidal waters when the projects are approved by local wetlands boards,
the Marine Resources Commission or the U. S. Army Corps of Engineers;
and
- Emergency work to protect life,
limb or property, and emergency repairs.
Parties uncertain as to whether or not a specific activity is regulated
should consult their local ESC program or the DCR ESC Program staff.
Minimum Standards
All regulated land-disturbing activities must comply with the 19 minimum
standards (MS) specified in Section 4VAC50-30-40 of the regulations
that are applicable to the specific project. All ESC programs are required
to confirm project compliance with minimum standards by reviewing ESC
plans and through onsite project inspection. However, an ESC program
may waive or modify any of the minimum standards that are deemed inappropriate
or too restrictive for site conditions by granting a written variance.
The full text of the 19 minimum standards is included in the VESCL&R,
and further discussion of their application is provided in the Virginia
Erosion and Sediment Control Handbook.
ESC Program Authority
Across the state, localities and DCR implement the provisions of the
ESC Program in accordance with the VESCL&R. Responsibility for program
implementation by each regulatory authority is further described below.
Local ESC Program Role
Most land-disturbing activities on privately owned lands must
be covered by an ESC plan approved by the locally operated ESC program
in the jurisdiction in which the activity is to be undertaken. Municipal
water and sewer construction projects on private lands are regulated
at the local level; the DCR ESC Program regulates activities by electric,
telephone, natural gas and railroad companies (see DCR ESC Program subsection
below). There are now 166 local ESC programs in Virginia. They include
every county, city and many incorporated towns (some towns are covered
by a county program). Specific provisions within local ordinances account
for program administration, plan review and approval, site inspection,
complaint response and enforcement on locally regulated projects. Although
administrative procedures vary by locality, the basic components are
consistent statewide. Local authorities must approve a project's ESC
plan, including the name of a Responsible Land Disturber, before
land can be disturbed. Such approval may be part of a permit process
and may require submission of an administrative fee and performance
surety set by the locality. Additionally, the local government or its
agent will periodically inspect approved projects.
Land-disturbing activities that cross local jurisdictions may be regulated
at either the local or state level. The applicant has the option of
submitting the ESC plan to each locality involved or to DCR. Inspection
and enforcement of multi-jurisdictional projects is generally carried
out at the local level.
Soil and Water Conservation Districts (SWCDs) often support local ESC
programs. SWCDs may assist with ESC plan review, handle inspection responsibilities,
assist with public education efforts and provide technical assistance.
Further information, including a directory of current SWCD contacts
and maps, is available from the SWCD page on DCR's website.
Contact information and specific local program requirements may be
available from the given locality's website. The Commonwealth of
Virginia website, http://www.state.va.us, provides links to such
websites.
State ESC Program Role
DCR's ESC Program regulates land-disturbing activities on state and
federal lands, as well as on a specific group of activities undertaken
by utility, interstate and intrastate pipeline and railroad companies.
The state program is carried out through nine regional Watershed Offices.
All land-disturbing activities on state agency land must be
covered by an ESC plan or annual ESC "specifications," including
a identification of a Responsible Land Disturber, approved by
the DCR ESC Program. However, plans must be consistent with local requirements
that may be more stringent than the VESCL&R. State program staff
is responsible for plan review and approval, site inspection, complaint
response and enforcement on these projects. Additionally, to assist
local ESC programs,
DCR establishes statewide standards and guidance, periodically reviews
local programs, and provides training and educational opportunities.
The DCR ESC Program also regulates a specific list of land-disturbing
activities (outlined at Section 10.1-563D of the law) undertaken by
utility, interstate and intrastate pipeline, and railroad companies.
These companies are required to prepare project-specific plans and annually
submit general ESC specifications to DCR for review and approval. State
staff conducts inspection and enforcement on these projects.
Activities on federal land must comply with the law and applicable
federal nonpoint source pollution programs on all regulated land disturbing
activities in the state. The law gives the Virginia Soil and Conservation
Board and local ESC programs authority to cooperate and enter into agreements
with federal agencies to facilitate ESC compliance. The federal agency
is responsible for achieving compliance through separate agreements/contracts
with onsite developers, regular field inspection, prompt enforcement
action against non-compliant projects and/or other mechanisms consistent
with agency policy.
Virginia Soil and Water Conservation Board
The Virginia Soil and Water Conservation Board has authority to provide
oversight and enforcement for the Virginia ESC Program. This board meets
periodically to address issues related to the Training and Certification
Program, results of local ESC Program reviews, Alternate Inspection
Programs and complaint resolution.
Training and Certification
The DCR ESC Program offers various training and certification opportunities.
Further details are available at the training and certification
page.
Erosion and Sediment
Control Handbook
In 1992, DCR published the Virginia Erosion and Sediment Control Handbook
as the primary guidance document for all ESC programs. The handbook
covers basic ESC concepts, ESC measure design, installation and maintenance,
plan review procedures and administrative guidelines to support compliance
with the VESCL&R. |
