The methodology to be followed for larger trees (height of 5 feet or more) is a cut-stump herbicide treatment, which consists of cutting the tree down near the base and applying an herbicide on the stump to prevent re-

4 growth. Stumps must be cut as low to the ground as possible within 1 inch of the soil or closer. Also, stumps must be cut as parallel to the ground as possible so herbicide does not run off. Smaller trees (less than 5 feet in height) may be left in place for foliar herbicide treatment. The cut surfaces of freshly cut stumps and stubs must be painted or sprayed immediately (within 5 minutes) with an herbicide labeled for stump treatment. Tree stumps greater than 3 inches in diameter, shall have one application hole drilled in the cambium layer of the tree with a 3/8 th inch drill bit for every 3 inches of diameter. For example, a six-inch diameter tree trunk would have two application holes drilled to aid the herbicide application. On all stumps, the cambium area next to the bark is the most vital area to wet. Contractor must have a licensed herbicide applicator (Qualified Supervisor License issued by the State of Arizona Department of Agriculture) on staff that is responsible for providing herbicide and applying it at recommended rates. A Qualified Supervisor or Certified Operator shall apply all herbicide. Contractor is responsible for following all manufacturer s label instructions when using the herbicide for cut stump treatment, including application rates, site and weather conditions, safety instructions, and regulations. In addition, contractor needs to add blue dye to the herbicide as a marking agent so contractor and the District can positively identify which stumps have been treated. The herbicide used needs to be approved for aquatic application. Suggested chemical active ingredient is imazapyr. Imazapyr (Aresenal 50, Habitat, Polaris) with a blue indicator dye. Work needs to be performed on a day with calm conditions, with temperatures under 90 degrees F, and with no imminent precipitation. Foliar Herbicide Treatment Smaller trees less than 5 feet in height will be treated with a foliar application of herbicide. Saltcedar foliage should be completely covered, and the terminal ends of all branches (including blooms) should be wetted without allowing dripping to occur. The interior of the plant should then be laced with the spray solution to complete treatment. Ground application of 1 percent (1 gallon per 100 gallons of water with 0.25 percent surfactant and a blue indicator dye) imazapyr solution by volume to saltcedar foliage can be made with a variety of spraying equipment such as hand-held pump-up or backpack sprayers, tractor-towed tank sprayers, or ATV-mounted low and high-powered sprayer systems. An adjustable cone nozzle (X6 to X8 orifice size) can be used to deliver a coarse spray (large droplets). A nonionic surfactant (0.25 percent by volume) and a blue indicator spray dye should be added to the mixture. Since absorption of herbicide into the foliage is relatively slow, work needs to be performed during calm weather conditions with low air temperature (below 90 degrees F). Care should be taken to not overspray, or have drippings onto the ground.

5 Disposal of Material Brush, twigs, and sawdust shall be promptly and completely cleared from the channel bottom and banks. All wood shall be chipped and transported to an off-site disposal area for proper disposal by the contractor. Contractor is responsible for all disposal fees. Site Cleanup All property shall be returned to the condition it was in prior to commencement of work, with the exception of trees removed. Site walk-throughs shall be conducted by the Flood Control District to document existing conditions prior to the commencement of work and following the completion of work. Locations The work will include removal and treatment of tamarisk on the west side of the Santa Rosa flood control channel between Honeycutt and W. Smith Enke Road. Please see location map. EQUIPMENT REQUIREMENTS Equipment, tools and supplies to be supplied by the Contractor shall include, without limitation: Chain saws, in good working condition, with extra parts, chains, etc., and tools to maintain said chain saws in running condition. Saws shall be of sufficient size to be adequate for all tree removal operations. Self-feeding mechanical chipper, capable of chipping tree branches up to 12 in diameter Herbicide applicators and sprayers Herbicide and blue marking dye All fuel and fluids for trucks, saws, and chipper INSURANCE REQUIREMENTS Without limiting any of their obligations or liabilities, prior to executing a contract with the District, the Contractor, at its own expense, shall purchase and maintain the minimum insurance specified below with companies duly licensed or otherwise approved by the State of Arizona, Department of Insurance, and with forms satisfactory to the District. Each insurer shall have a current A.M. Best rating of not less than AVIII. Use of alternative insurers requires prior approval from District.

6 Commercial General Liability The Contractor shall maintain Commercial General Liability insurance with a limit of not less than $1,000,000 for each occurrence with a $5,000,000 General Aggregate Limit. The policy shall include coverage for bodily injury, property damage, personal injury, products and blanket contractual covering, but not limited to, the liability assumed under the indemnification provisions of this Contract which coverage will be at least as broad as Insurance Service Office policy form CG or any replacements thereof. The general aggregate limit shall apply separately to the work or service under this Contract or the general aggregate shall be not less than twice the required per occurrence limit. In the event the general liability insurance policy is written on a claims made basis, coverage shall extend for two years past completion and acceptance of the work or services as evidenced by annual Certificates of Insurance. Such policy shall contain a severability of interests provision (a.k.a. cross liability and separation of insured ); and shall not contain a sunset provision of commutation clause, nor any provision which would serve to eliminate third party action over claims.
