The UNIVERSITY of VERMONT UVM EROSION PREVENTION AND SEDIMENT CONTROL POLICY Prepared by: Krebs & Lansing Consulting Engineers, Inc. 164 Main Street Colchester, Vermont 05446 (802) 878-0375


I.

INTRODUCTION

The University of Vermont is one of the leading environmental universities in the country. In keeping with that principal, the University has adopted this “Erosion Prevention and Sediment Control Policy (EPSCP)” to protect the natural resources on campus, in the adjoining communities, and Lake Champlain. The policy is designed to formalize many existing erosion prevention and sediment control best management practices. The policy establishes a minimum requirement by which construction projects can be measured. The policy not only establishes a responsible party, but a requirement that the responsible party review and report on the construction activity. Erosion is the process where soil particles are displaced by water or air. The process of trapping or settling out soil particles after they are suspended in water is difficult. Therefore, the primary objective of this plan is sediment control. Sediment controls are non-structural best management practices that may assist in initially preventing erosion. Soil particles suspended in runoff can be harmful to fish and other wildlife, and they can impact recreational use of our natural resources. In addition to the impacts of the suspended soils, the sediment also carries nutrients (especially phosphorus and nitrogen) to its receiving waters and eventually to Lake Champlain. The Lake Champlain Phosphorus TMDL goals and objectives were included in the University EPSCP. It has been estimated that erosion cost this country approximately $4 billion dollars each year. II.

APPLICABILITY

The policy is applicable to land disturbances between 5,000 s.f. (approximately 70’ x 70’) and 1 acre (approximately 200’ x 200’). Land disturbance greater than 1 acre are subject to General Permit for Stormwater Runoff from Construction Sites. There is a separate General Permit if the project disturbs between 1 and 5 acres or if the project disturbs more than 5 acres. The following land disturbances are exempt from the EPSCP: 1) 2) 3)

Agricultural activities Silviculture activities Emergency activity (Immediate post-construction erosion control BMP’s are still required.)

EROSION PREVENTION AND SEDIMENT CONTROL PLAN A qualified University employee or a qualified consultant shall prepare an Erosion Prevention and Sediment Control Plan for each project. The amount of detail of the project shall be based on the area of the disturbed soil, proximate to natural resources and construction schedule. The requirements for all EPSC plans are as follows:

-

Name of responsible party. This is the person completing the erosion control inspections and compiling reports. (UVM project manager or outside consultant)

-

The responsible party shall report any project subject to this policy to Campus Planning Services. The projects may be included in the annual MS4 report to the State of Vermont Agency of Natural Resources.

-

The responsible party shall inspect erosion control once a week at a minimum. In addition to that, the responsibility party shall also inspect the site within 24 hours after a rain event greater than ½” in 24 hours. Site visits can halt once the area has been stabilized or frozen in winter months.

-

The University shall include in any “Request for Proposals” on projects that may include soil disturbance limits greater than 5,000 s.f. and less than 1 acre the following or similar language. “The University of Vermont has adopted an Erosion Prevention and Sediment Control Policy. The consultant shall be responsible for providing design services and construction administration services that comply with the policy.”

-

The University shall include in any construction bid documents on projects that may include soil disturbance limits greater than 5,000 s.f. and less than 1 acre the following or similar language: “The University of Vermont has adopted an Erosion Prevention and Sedimentation Control Policy. The Contractor shall be responsible for providing construction services that comply with the policy.”

-

Preconstruction meeting with contractor is required to discuss EPSC plan and policy.

-

Keep unnecessary construction traffic off disturbed soils. Provide stabilized construction entrances or truck washes if necessary.

-

Standard erosion prevention construction details are provided in this appendix of this policy for use on projects where appropriate.

-

Stockpiles of soil left for more than 2 weeks shall be temporarily seeded and mulched.

-

All projects that have exposed soils between October 15th and April 15th, shall have daily cover. The daily cover shall be twice the standard hay mulch rate or erosion control blanket. Schedule projects between April 15th and October 15th, if practicable. Trenches and excavations for foundations are exempt from daily cover. Page 2


-

If sediment is found to be eroding or tracking off site, it is the “responsible party’s� obligation to document the erosion, determine its cause and make adjustments to ERSC plan to prevent or minimize future off site sediment loss. All improvements shall be installed within 2 working days. The Contractor shall be responsible for cleaning up tracked or eroded sediment both on the University Campus and off campus.

-

Install temporary fencing as necessary to protect pedestrians from construction zone and to prevent construction zone from expanding beyond minimum necessary limits.

-

Contractor shall use water to prevent blowing dust or sediment. Only use calcium chloride if water has been tried and was ineffective.

-

Install permanent erosion and sediment control structures at the earliest practicable time in the construction phase.

-

Minimize the area that is disturbed for construction.

-

Divert and convey offsite runoff around disturbed soils and steep slopes to stable areas in order to prevent transport of pollutants off site.

-

After the construction area has been vegetated or stabilized, the Contractor shall remove temporary control structures and restore the affected area. Dispose of sediments in accordance with State and Federal regulations. This work should be done prior to October 15th if practicable.

-

All storm drain inlets that are made operable during construction should be protected so that sediment-laden water will not enter the conveyance system without first being filtered or otherwise treated to remove sediment.

-

This policy shall prohibit sediment-laden water from being pumped out of excavations into the storm system without adequate treatment. Treatment may include one or more of the following: temporary sediment basin, vegetative treatment strip, filter bag, or approved equal.

1)

If project disturbs greater than 5,000 s.f. but less than 20,000 s.f.:

-

If all site work will start after April 15th and be complete by October 15th including topsoil, seeding and mulching, an erosion control drawing of the site is not required. Schedule of construction is required. A brief narrative describing sediment control and erosion prevention practices shall be prepared.

2)

If project disturbs more than 20,000 s.f. and less than 1 acre:

-

A map shall be prepared showing proposed erosion control best management practices.

-

A narrative shall be prepared describing sediment control best management practices. Page 3


-

When sections of the project are at finish grade and they can be avoided with construction equipment, they shall be topsoiled, seeded and mulched. Phasing the topsoil, seed and mulch is required as of October 15th.

IV.

ENFORCEMENT

-

Responsible party is obligated to enforce this policy. Responsible party shall keep reports of all erosion control inspections. Contractor must comply with erosion control measures or responsibility party/Owner will implement corrections and backcharge Contractor.
