Appendix A - (Excerpt from Integrated Pest Management Program)

4. .Chemical Application Methods

• Hand/select

• Spot

• Broadcast

• Aerial

4.1.Hand/Select

Any of the following hand/select methods may be employed:

• Wicking and wiping

• Basal bark

• Frill or hack and squirt

• Stem injection

• Cut-stump

4.2.Spot

Chemical applications are made by either ground-based sprayers (mounted to small all-terrain vehicles (ATVs), trucks or tractors), or with backpack sprayers. These applicators range from motorized vehicles with spray hoses, to backpack sprayers, to hand-pumped spray or squirt bottles. Hand-pumped spray and squirt bottles can target very small plants or parts of plants.

4.3.Broadcast

A boom (a long horizontal tube with multiple spray heads) is mounted or attached to a helicopter, airplane, tractor, ATV, or other vehicle. Nozzles control the droplet size and the area being covered. Boomless nozzles and backpack sprayers may also be used as a broadcast tool.

4.4.Aerial

Helicopters may be used for aerial application of sprays or granules for rapid broadcast coverage of large or inaccessible areas. Aerial application of chemicals has been used only on larger tracts of steep, rugged land with no road or trail access, but shall not be employed within 300 feet of water. The Corps must provide notification to, and coordinate with, the regulatory agencies prior to a large-scale aerial application.

5. Herbicides & Chemicals The following table (Table 3) lists the active ingredients allowed for use in the District5 and identifies some common trade (label) names, although these labels are not the only ones that are allowed for use for each of the active ingredients.

Any of these chemicals may be used during the spraying season, and applied by the application methods, with buffers and wind speeds, described in the following table. The following table (Table 4) lists the adjuvants allowed for use in the District.

The following table (Table 5) illustrates specific buffer distances and wind speeds by application method for chemical applications in the District.

5 Another form of vegetation control that does not necessarily fit into any of the other categories will be environmentally friendly products such as ordinary vinegar.

The buffer is measured from the ordinary high water mark (OHWM)6. For the purposes of this document, the OHWM shall be the point from which all buffers in this document shall be measured, and includes, but is not limited to rivers, streams, lakes, ponds, reservoirs, ditches draining into fish-bearing waters, seasonal streams, intermittent streams, ephemeral streams, and concrete channels draining into or containing fish. For reservoirs on Corps lands, the OHWM is defined as the maximum normal operating pool elevation. The wind speeds have been limited to two categories for implementation, and the wind direction must not be in the direction of the adjacent water body during applications.

6 The OHWM is defined in 33 CFR §329.11.

Through ESA consultation, the Corps has identified specific controls for some of the active ingredients:

• Only aquatic labeled herbicides and surfactants shall be used for use within 15 feet of “live” waters or areas with shallow water tables.

• Picloram shall not be applied within 100 feet of water or be sprayed in roadside ditches (dry or wet) that drain to fish-bearing streams.

• The buffer is measured from the ordinary high water mark (OHWM).

• Applications shall not occur when the wind direction is in the direction of the adjacent water body during applications made less than 300 feet from water.

• Marker dyes shall be used to assist in determining proper coverage and targeting of treated species.

Applications shall utilize nozzles and pressures that produce droplets in the 177 to 428 micron range (medium, coarse, very coarse) to reduce the possibility of drift. Nozzles and pressures, which create droplet sizes of 176 microns or less, shall not be used. Droplet sizes of 429 microns or larger (extremely coarse and ultra coarse) are acceptable and encouraged, provided that the volume of the spray solution is not so great as to cause runoff and leaching problems.
