1.5.1 Soil Moisture

Soils to be treated shall be tested immediately before application. Test soil moisture content to a minimum depth of 3 inches. The soil moisture shall be as recommended by the herbicide manufacturer. The herbicide will not be applied when soil moisture exceeds manufacturer's recommendations because herbicides do not adhere to the soil particles in saturated soils.

1.5.2 Runoff and Wind Drift

Do not apply herbicide during or immediately following heavy rains. Applications shall not be performed when conditions may cause runoff or create an environmental hazard. Applications shall not be performed when average wind speed exceeds 10 miles per hour. The herbicide shall not be allowed to enter water systems, aquifers, or endanger humans or animals.

1.5.3 Placement of Concrete

Place concrete covering treated soils as soon as the herbicide has reached maximum penetration into the soil. Time for maximum penetration shall be as recommended by the manufacturer.

1.6 WARRANTY

The Contractor shall provide a 5-year written warranty against any new vegetation growth under this contract. Warranty shall include annual inspections of the fence line. If live vegetation is discovered during the warranty period, and the soil has not been altered in the interim:

a. Retreat the soil and perform other treatment as may be necessary for elimination of vegetation;

b. Repair damage caused by vegetation; and

Submit manufacturer's label and Material Safety Data Sheet (MSDS) for herbicides proposed for use. Provide herbicides currently registered by the EPA. Non-repellant herbicides shall be selected for maximum effectiveness and duration after application. The selected herbicide shall be suitable for the soil and climatic conditions at the project site and applied at the highest labeled rate. Submit samples of the herbicides used in this work. The Contracting Officer may draw, at any time and without prior notice, from stocks at the job site; should analysis, performed by the Government, indicate such samples to contain less than the amount of active ingredient specified on the label, work performed with such products shall be repeated, with herbicides conforming to this specification, at no additional cost to the Government.

PART 3 EXECUTION

3.1 VERIFICATION OF MEASUREMENT

Once herbicide application has been completed, measure tank contents to determine the remaining volume. The total volume measurement of used contents for the application shall equal the established application rate for the project site conditions. Provide written verification that the volume of herbicide used meets the application rate.

3.2 TECHNICAL REPRESENTATIVE

A DOD certified herbicide applicator or Vegetation Management Quality Assurance Evaluator (QAE)/Performance Assessment Representative (PAR) shall be the technical representative, shall be present at all meetings concerning treatment measures for vegetation, and shall be present during treatment application. The Civil Engineering Project Manager shall be contacted prior to starting work.

3.3 SITE PREPARATION

Work related to final grades, landscape plantings, foundations, or any other alterations to finished construction which might alter the condition of treated soils, must be coordinated with this specification.

3.3.1 Ground Preparation

Eliminate vegetation sources by removing debris from clearing and grubbing from the site, before herbicide application begins.

3.3.2 Verification

Before work starts, verify that final grades are as indicated and smooth grading has been completed in accordance with Section 31 00 00 EARTHWORK. Soil particles shall be finely graded with particles no larger than 1 inch and compacted to eliminate soil movement to the greatest degree.
