SECTION 32 05 33 Page 3 number of square yards of reno mattress installed as directed by the Contracting Officer.

2.1.1 Materials and Construction

Reno Mattress is a wire mesh container uniformly partitioned into internal cells with relatively small height in relation to the other dimensions.

The internal cells are interconnected with other units and filled with stone at the project site to form flexible, permanent monolithic structures used for channel bottom protection. The reno mattress shall have the dimensions as shown on the contract drawings.

The wire mesh shall be non-raveling mesh made of twisting continuous pairs of wires to form hexagonal shaped openings which are interconnected to adjacent wires. The wire is made from zinc coated and overcoated with PVC.

PVC coatings shall not show cracks or breaks after the fabrication of the mesh. Fasteners used to assemble and interconnect the individual units shall be made of stainless steel.

The stones for the reno mattress shall be between 4" and 6" in diameter.

The stones shall meet the specifications of the Rip Rap, Section 7.107 of this contract.

The subgrade shall be excavated to allow for the placement of the reno mattress to form the grade shown of the contract drawings. The reno mattress shall be placed on geotextile fabric laid directly on the compacted subgrade.

2.2 WATER

Source of water must be approved by the Contracting Officer, and be of suitable quality for irrigation. Use collected storm water or graywater when available.

2.3 HERBICIDES

The Contractor must apply a NYS approved herbicide to persistent herbaceous and woody growth in accordance with the Contract Drawings and as directed by the Contracting Officer. The Contractor must secure all necessary state and local permits for the application of herbicide and adhere to any specific permit requirements or special conditions.

2.3.1 General Regulations for Herbicides

The Contractor must carefully protect all plant material and structures during and following the herbicide application. Any repair to damaged plants and structures resulting from herbicide application must be repaired by the Contractor at the Contractor’s own expense.

Invasive plants to be removed will be identified by the Contacting Officer.

2.3.2 Quality Assurance

The Contractor must submit an Herbicide Applicator that possesses a valid NYSDEC Type 5A - Aquatic Vegetation Pesticide Applicator Certification License and personnel training records.

The Contractor must develop an Herbicide Application Treatment Plan for the control of invasive species prior to performing any construction

SECTION 32 05 33 Page 4 activities. The plan must contain information on the products to be sprayed (including manufacturer’s recommended application procedures and rates and all applicable material safety data sheets, the proposed schedule of herbicide application(s), credentials and certifications for all of the personnel that will be applying the herbicide. All appropriate health and safety data records and procedures to be implemented. Prior to execution of the herbicide application treatment plan, the Contractor must submit the plan for approval by the Contracting Officer.

2.3.3 Materials and Methods

1. The work will eradicate invasive, non-native plants in upland and wetland areas using NYS approved herbicide for eradication of all plants except Oriental Bittersweet, which will be treated with Garlon

4. All chemicals to be applied using backpack and hand-held sprayers and individual stem wipe or injection applications. Herbicides application to open water/marshlands is prohibited.

2. In wetlands, the Contractor must spray NYS approved herbicide or approved equal onto specified weedy growth only, as directed and approved by the Contracting Officer, between May and September.

3. All vine and invasive plant material must be removed by hand. The removal of these plant and materials must be from existing trees, fence lines, utility poles and lines, adjacent structures, BMP sites, and other areas within the watershed. All vines and invasive plant material removed must be disposed of by the Contractor at the Contractor’s own expense.

4. Invasive tree climbing vines, including but not limited to Oriental bittersweet (Celastrus orbiculatus), porcelainberry (Ampelopsis brevipedunculata), greenbrier (Smilax spp.), honeysuckle vine (Lonicera spp.), must be cut flush to the ground. Herbicide must be applied to the cut stumps of the tree climbing vines where possible as determined by the Restoration Specialist and approved by the Contracting Officer. The herbicide applied to the cut stump must be pure product not having been mixed with water. Once tree climbing vines have been cut, they are to be left in place until leaf material and clinging tendrils dry out. Invasive vines must then be removed from the trees by hand and as directed by the Restoration Specialist taking care to avoid damaging the trees.

5. The applicator must spray to wet--not to the point of runoff. Care must be taken to properly calibrate the tank nozzle so as to direct herbicide spray only onto the undesirable plants and obtain complete coverage of leaves and stems. Avoid spray drift onto desirable plants and minimize spray contact with soil. It is recommended to spray when plants are not under water stress. Only flat pan nozzles must be used when using a spray applicator.

6. In areas where invasive plants are tightly intermixed with native plants, the applicator must use the individual wipe or injection method to prevent the accidental treatment of desirable plant material. Marking dyes must be added to the herbicide at the request of the Contracting Officer to prevent the accidental treatment of desirable plant material.

7. Apply on a warm sunny day (75 degrees to 90 degrees preferred). Do not spray if wind speed exceeds 5 mph or if weather conditions would decrease the effectiveness of the herbicide or increase the intended target area.

Do not apply or allow herbicide spray into surrounding waterbodies. Do not exceed the rates indicated on product labels.

SECTION 32 05 33 Page 5

8. A non-ionic surfactant that is labeled for use with herbicides must be added to the herbicide to help penetrate targeted plants for increased control. Surfactant must contain 50% or more active ingredient.

9. When using water from on-site hydrants, remove all suspended particles that may reduce the effectiveness of the herbicide prior to adding the water to the mixing tank.

10. All treated areas must be temporarily posted with signs indicating that the area has been treated with herbicide. Signs must be clearly posted in areas where the public may come into contact with the plant material.

11. The Contractor must return to the site after fifteen (15) calendar days and remove any dead vegetation that may interfere with planting of new material. If a second application is deemed necessary, a minimum of fifteen (15) calendar days is required before the Contractor can remove any remaining dead vegetation and begin installing any new plant material.

Planting may proceed when the site is deemed acceptable to the Contracting Officer.

12. Any sucker or new growth that emerges post removal operations must be removed or treated by the Contractor, either manually or by hand wiping with herbicide, throughout the duration of the two consecutive growing season plant guarantee.

13. The plant species to be eradicated must primarily include:

common reed (Phragmites australis)

Additionally, other species to be eradicated that may or may not be present at the site include additional species at the direction of the Contracting Officer:

Asiatic sand sedge (Carex kobomugi) black locust (Robinia psuedoacacia) burning bush (Euonymus alatus) common ragweed (Ambrosia artemisiifolia)

English ivy (Hedera helix) giant hogweed (Heracleum mantegazzianum) giant ragweed (Ambrosia trifida)

Japanese honeysuckle (Lonicera japonica)

Japanese knotweed (Polygonum cuspidatum)

Japanese stiltgrass (Microstegium vimineum) mile-a-minute vine (Polygonum perfoliatum) mugwort (Artemisia vulgaris) mutiflora rose (Rosa mutiflora)

Russian olive (Elaeagnus angustifolia) tree of heaven (Ailanthus altissima) white mulberry (Morus alba)

14. Herbicide application(s) to monoculture stands of common reed shall occur no sooner than August 1st. Herbicide application(s) to all other invasive and non-native plants shall occur no sooner than July 1st.
