SOIL EROSION, SEDIMENT CONTROL & SEEDING NOTES

1. All soil erosion/sediment control measures shall comply with the “2011 Maryland Standards and

Specifications for Soil Erosion and Sediment Control” and the provisions of the approved plan.

2. All grading and stabilization shall comply with the “2011 Maryland Standards and Specifications for

Soil Erosion and Sediment Control”, “Section B - Grading and Stabilization” and the provisions of the

approved plan.

3. All soil erosion and sediment control practices (BMP's) are to be constructed and/or installed prior to

or at the initiation of grading in accordance with “2011 Maryland Standards and Specifications for

Soil Erosion and Sediment Control”, and the approved plan.

4. A grading unit is the maximum contiguous area allowed to be graded at a given time and is limited to

20 acres. Work may proceed to a subsequent grading unit when at least 50 percent of the disturbed

area in the preceding grading unit has been stabilized and approved by the enforcement authority

and/or the Washington County Soil Conservation District (approval authority). Unless otherwise

specified and approved by the approval authority, no more than 30 acres cumulatively may be

disturbed at a given time.

5. For initial soil disturbance or re-disturbance, temporary or permanent stabilization must be

completed within:

a) Three (3) calendar days as to the surface of all perimeter dikes, swales, ditches, perimeter

slopes, and all slopes steeper than 3 horizontal to 1 vertical (3:1); and

b) Seven (7) calendar days as to all other disturbed or graded areas on the project site not

under active grading.

6. Stockpiles must be stabilized in accordance within the 7 day stabilization requirement, as well as,

Standard B-4-1 Incremental Stabilization and Standard B-4-4 Temporary Stabilization (as

applicable).

7. All constructed channels and swales shall have specified treatment installed to the design flow depth

completed downstream to upstream as construction progresses. An installation detail shall be

shown on the plans.

8. All storm drain and sanitary sewer lines not in paved areas are to be mulched and seeded within 3

days of initial backfill unless otherwise specified on plans.

9. Electric Power, telephone, and gas lines are to be compacted, seeded, and mulched within 3 days

after initial backfill unless otherwise specified on plans.

10. No slope shall be greater than 2:1.

11. As required by Section B, of the Maryland Standards and Specifications for Soil Erosion and

Sediment Control, “Adequate Vegetative Stabilization”, is defined as 95 percent ground cover. The

Washington County Soil Conservation District requires the project adhere to this for scheduling of

the Final Site Closeout Review, and/or release of the site for soil erosion and sediment control.

For sites 1.0 acre or more, the following are required:

A. Maryland Department of the Environment, General Permit for Stormwater Associated with a Construction

Activity, NPDES Permit Number MDR10, State Discharge Permit Number 09GP, or an Individual Permit.

B. The Maryland Department of the Environment

(General/Individual Permit - Notice of Intent- NOI) application and permit shall be posted and/or available

on-site at all times.

C. During construction, all soil erosion and sediment control practices (BMP's) shall be inspected and

recorded on the “Standard Inspection Form”, “General Permit for Stormwater Associated with Construction

Activity” per the Maryland Department of the Environment (General/Individual Permit - Notice of Intent -

NOI).

D. Following construction and release of the site for soil erosion and sediment control by the Washington

County Soil Conservation District( i.e., all portions of a site have been permanently stabilized, and all

stormwater discharges from construction sites that are authorized by the permit are eliminated) the

authorized permittee shall submit the Maryland Department of the Environment, General/Individual Permit

- Notice of Termination-NOT.
