Sullivan County, Missouri Nationwide Permit 27

Site Description (See Exhibit 1) SE 1/4, Sec. 10, T64N, R20W, Sullivan County, MO NE 1/4, Sec. 15, T64N, R20W, Sullivan County, MO

The subject site is a bottom land site located approximately 2 miles west of Pollock, MO. The proposed construction will result in a wetland pool open to floodwater with a normal pool of approximately 10.5 acres.

Drainage Area The total drainage area within the pool is 50 acres. The drainage area is shown on Exhibit 1.

Description of Best Management Practices (BMP’s) One or more of the following temporary or permanent BMP’s will be installed or practiced on the site. Other practices not listed may be used during the course of construction if deemed necessary by NRCS in order to comply with permit requirements. Detailed descriptions of the BMP’s are provided on the Pollution and Erosion Control Plan (Exhibit 2), and/or the applicable Construction Specification Sections of the Construction Contract as indicated below.

Brush Pile Filters (5) Culverts (5) Protective Dikes (5) Sediment Basins (5) Seeding/Mulching (6) Silt Fence (5) Straw Bale Filters (5) Temporary Mulching (5 & 6) Underground Outlets (5) Rock Outlets (719) Grass-lined Channels (5) Rip Rap Channels (5) Diversions (5) Grass Filter Strips

Housekeeping – Handling, storage and disposal of chemical pollutants such as fuels, lubricants and human waste will be in accordance with Construction Specification 5 of the Construction Contract and with all applicable state and federal regulations concerning storage, dispensers, spill prevention, control and counter measures. An equipment parking area is designated on the Pollution and Erosion Control Plan (Exhibit 2).

Disturbed Areas Clearing and grubbing and borrow limits are shown on Exhibit 2. In addition, vegetation and top soil will be stripped from foundation of floodway, berms and spoil berms. The total area to be disturbed is approximately 7.5 acres.

Installation of BMP’s BMP’s will be installed at the locations shown on the Pollution and Erosion Control Plan (Exhibit 2). Installation will be in accordance with the appropriate Construction Specification, the Pollution and Erosion Control Plan (Exhibit 2), and other applicable drawings.

Temporary and Permanent Non-Structural BMP’s

1. Staging of activities – Stripping, clearing, grubbing and earthwork activities will be staged in accordance with Construction Specification 5. Temporary brush dams will utilize cleared brush to assist in controlling sediment where feasible.

2. Temporary mulching – Disturbed areas will not be allowed to remain exposed during extended periods of construction inactivity. Temporary mulch will be applied in accordance with Construction Specifications 5, and the General Clauses of the contract.

3. Seeding and Mulching – Permanent seeding and mulching will be installed on all disturbed areas above the Principal Spillway elevation in accordance with Construction Specification 6.

Temporary and Permanent Structural BMP’s Temporary diversions will be installed above the borrow areas in accordance with Construction Specification 5 to divert surface runoff as shown on Exhibit 2.

Sediment Basin A temporary sediment basin will be installed below the principal spillway outlet as shown on Exhibit 2. The primary purpose for this basin is to protect the stream below the construction site. The sediment basin will be maintained in accordance with Construction Specification 5 until permanent vegetation is established on the site.

Inspection NRCS will inspect the construction site at least once per week during periods of construction activity to ensure all installed BMP’s and other pollution control measures are properly installed, operating and maintained. In addition, NRCS will conduct a site inspection within 72 hours following heavy rains provided the disturbed areas have not been finally stabilized with permanent BMP’s and vegetation. During site inspections, locations where storm water leaves the site (below the sediment basin) will be inspected for evidence of erosion or sediment deposition. Any deficiencies found during inspections will be corrected within seven calendar days. NRCS will promptly notify the site contractor responsible for operation and maintenance of the BMP’s of any deficiencies.

A log of each inspection (NRCS-USDA Form MO-ENG-C95, Exhibit 3) will be kept in the project file.

Amendments This SWPPP will be amended and updated during the term of the land disturbance activity when:

a. Design, operation, or maintenance requirements of BMP’s is changed;

b. Design of the construction project is changed in a manner that could significantly affect the quality of the storm water discharges;

c. NRCS inspections indicate deficiencies in the SWPPP or any BMP;

d. MDNR notifies NRCS of deficiencies in the SWPPP;

e. The SWPPP is determined to be ineffective in significantly minimizing or controlling erosion and sedimentation (e.g., there is visual evidence, such as excessive sediment deposits in streams or channels);

f. Total Settleable Solids from storm water outfall exceed 2.5 ml/L/hr; or

g. MDNR determines violations of Water Quality Standards may occur or have occurred.

Sampling and Effluent Limitations Although there are no routine sampling requirements, discharges from the site (Settleable Solids) are limited to a maximum of 2.5 ml/L/hr for each storm water outfall.

Reporting of Other Discharges

1. Hazardous Substance and Oil Spill Reporting

2. Removed Substances

3. Change in discharge: In the event soil contamination or hazardous substances are discovered at the site during land disturbance activities, NRCS will notify MDNR in writing.

Records Records required by permit, including a copy of the General Permit, this SWPPP including all amendments, results of any monitoring and analysis, and all site inspection records will be kept at the NRCS Chillicothe Wetland Office, 1100 Morton Parkway, Chillicothe, MO 64601 until the construction contract for the site is completed and closed. After closure of the construction contract the records will be kept in the NRCS State Office in Columbia, Missouri for a period of at least three years from the date of the Letter of Termination.
