DESCRIPTION

Structure Site No. 18 is a single-purpose earthen dam designed in 1967 for flood prevention with the construction completed in 1970. The structure is an integral part of the Pine Creek Watershed Site No. 18 is located approximately 5 miles east of Powderly, Lamar County, Texas. The site is situated within the Blackland Prairie and East Cross Timbers physiographic area of Lamar County, Texas.

The following items will be repaired as shown in the drawings: the plunge pool and plunge pool fencing.

The major items of work requiring inspection are approximately 2 acres of vegetation establishment; 1,346 square yards of geotextile; 1,104 tons of rock riprap; 19.2 cubic yards of select gravel backfill; approximately 4,925 cubic yards of site preparation; and 650 linear feet of new fencing.

Soil disturbing activities will include (in no order): construction of the access road and construction campsite; site preparation earthwork; geotextile and rock-riprap installation; erection of new fencing; and disposal of waste materials.

RUNOFF COEFFICIENT

The pre and post-construction CN for the site will be essentially the same. The contractor will be required to maintain dewatering capabilities during the duration of the contract.

SITE AREA

The work limits of the site encompass approximately 4.6 acres (more or less) including the construction campsite, access road, stockpile, waste, and borrow areas. The areas disturbed by construction activities total 2.6 acres of which 2 acres will be re-vegetated.

SEQUENCE OF MAJOR ACTIVITIES

The estimated order of activities will be as follows:

1. Construct the access road and campsite, including any necessary site prep activities and fence removal

2. Construct water control measures

3. Foundation stripping and subgrade preparation of waste, and borrow areas

4. Reconstruct and shape plunge pool and plunge pool outlet channel

5. Install geotextile and rock riprap plunge basin armoring

6. Install geotextile and watering ramp material

7. Final shaping and grading including removal of water control measures

8. Final restoration of disturbed areas

9. Fencing

10. Vegetation

11. Cleanup and Demobilization

NAME OF RECEIVING WATERS

Site 18 is located on an unnamed tributary that flows into Pine Creek (Segment 0202D).

Data provided by the U.S. Fish and Wildlife Service indicates that Lamar County does have endangered species present in the county. However, Lamar County is not identified as a critical habitat for these species.

There are no properties listed or eligible for listing on the National Register of Historic Places in the vicinity of the work area.

CONTROLS

EROSION AND SEDIMENT CONTROL

STABILIZATION PRACTICES

Temporary Stabilization - The average annual rainfall in the area is 46 to 50 inches. Sediment filters, consisting of silt fences will be used during construction to help stabilize disturbed areas. Sediment filters are to be provided along the downstream boundary of any area which is stripped of vegetation during any phase of construction. Sediment filters are also to be provided on the downstream side of any soil material which is stockpiled for more than 14 days. All disturbed areas not covered in armoring shall be hay mulched after seeding of permanent vegetation.

After borrow operations are completed or as soon as practicable after temporary activity has ceased in an area it will be scarified as required in the specifications. All excavated slopes within the limits of the borrow area shall be maintained to be no steeper than 1:1 except that the final side slopes of all borrow areas shall be dressed and be no steeper than 3:1.

The construction ingress and egress will be stabilized with gravel or other stabilization materials to prevent the tracking of mud onto public streets by vehicles leaving the construction site.

All pollution control measures will be maintained in a functional condition as long as needed during the construction operation.

Permanent Stabilization - All cut slopes, earthfill slopes, and disturbed areas not covered with rock riprap will be protected against rilling and erosion by vegetation. Topsoil will be placed on the wave berm above the rock riprap armoring and other disturbed areas to facilitate vegetation establishment. Temporary stabilization measures will remain in place until coverage by permanent vegetation is at least 70 percent.

Structural Practices – No structural measures are anticipated for erosion and sediment control.

STORM WATER MANAGEMENT

Storm water runoff from the construction area will be filtered with sediment fences or other measures as needed around the excavation areas, embankment, stockpiles, campsite, and other disturbed areas as described above for EROSION AND SEDIMENT CONTROL. Where construction roads cross low areas subject to concentrated storm water flow, culverts will be installed.

OTHER CONTROLS

WASTE DISPOSAL

Waste Materials:

All organic materials from the site preparation, clearing, and clearing and grubbing operations will be either chipped and used on site for mulch or burned in accordance with all state and local regulations. If the materials are burned on site, the residues will be buried in the waste areas. All inorganic materials from the site preparation will be disposed of by burying in the waste areas and covering with a minimum of 3 feet of soil. All trash and construction debris will be collected and disposed of off-site.

Hazardous Waste:

All chemical and hazardous waste materials will be disposed of off-site in accordance with local or state regulation or as recommended by the manufacturer.

Sanitary Waste:

All sanitary waste will be collected from portable units and disposed of in accordance with local regulations.

Dust Control:

Dust will be controlled on all haul roads and access roads by sprinkling with water.

CERTIFICATION OF COMPLIANCE WITH FEDERAL, STATE, AND LOCAL

REGULATIONS

All local and State regulations will be adhered to concerning the burning of organic materials or disposal of organic, chemical, and sanitary waste. The repair project will be conducted in accordance with the U.S. Department of the Army Corps of Engineers Nationwide Permit No. 3 Maintenance. The Texas Commission on Environmental Quality (TCEQ) has issued Texas Pollutant Discharge Elimination System (TPDES) permits for storm water discharges from construction activities under Section 402(p) of the CWA. There are no other applicable State or Federal requirements for sediment and erosion site plans or storm water management site plans.

MAINTENANCE AND INSPECTION PROCEDURES

The Contractor, ______________________________________, will be responsible for intermittent review and inspection of the operation and maintenance of all pollution control measures throughout the life of the contract. Inspection of the conditions and the need for repair shall be made within 24 hours of each rainfall event of 0.5 inch or greater. Daily inspections of the need for cleanup of chemical spills and sanitary facilities will be performed.

Routine inspection of disturbed areas, storage areas, stockpiled materials, traffic areas and sediment filters shall be made every seven (7) days.

A maintenance inspection report will be made after each inspection. The report will be documented in the contractor’s and the project engineer’s daily job diary maintained on the job. The report will be prepared in accordance with Part V of the general permit.

The report will document the dates when major grading activities occur, the dates when construction activities temporarily or permanently cease on a portion of the site, and the dates when stabilization measures are initiated. Each report will be attached to the Storm Water Pollution Prevention Plan (SWP3) and remain with the SWP3 on site. Each report will be retained as part of the SWP3 for at least three (3) years from the date the site is finally stabilized.

The SWP3, a copy of the permit or permit language, and all inspection reports shall be available at a central location on site for the use of all operations and those who have responsibilities under the SWP3.

NON-STORM WATER DISCHARGES

It is expected that the following non-storm water discharges may occur from the site during the construction period:

Water for dust control Water for adjustment of moisture in earthfill and backfill operations

INVENTORY FOR POLLUTION PREVENTION PLAN
