This permit does not apply to the use of he rbicides in lakes or ponds (this includes man-made and natural ponds). The Aquatic Plant and Algae Management General

Permit covers all in-lake activities.

Persons conducting herbicide applications shall obtain permit coverage under the general permit for the following noxious weed and quarantine list weed control

activities:

1. Into waterbodies that are contiguous with rivers or streams, or

2. Into marine or estuarine waters, or

3. Along the shorelines of lakes, ponds, reservoirs, rivers, streams, or

4. In other situations as determined by Department of Ecology (Ecology).

B. Activities Excluded From Coverage Under This Permit

The following water bodies and activities are excluded from c overage under this permit:

1. Constructed detention or retention po nds for wastewater or stormwater treatment or control covered by a separate individual or general NPDES or state permit.

The use of herbicides on the following s ites does not require coverage under any aquatic pesticide permits issued by Ecology:

* Words in bold typeface are defined in Appendix A – Definiti ons and Acronyms.

January 16, 20083

2. Man-made detention or retention ponds designed specifically for wastewater or

stormwater treatment that do not have an outlet to surface waters of the state

, or ponds that will not discharge to othe r water bodies during and for two weeks following treatment.

3. Upland farm ponds with no discharge to other surface waters of the state during and for two weeks following treatment.

4. Any constructed water body five acres or less in surface area with no discharge to other surfac e waters of the state during and for two weeks following treatment.

5. Any noxious weed activities con ducted on seasonally dry land surfaces (including seasonally dry wetlands) as l ong as the active ingredient is not biologically active when the water returns.

6. Any research activities when pesticides or adjuvants are being applied to water bodies under a state experimental use pe rmit (sites are less than one acre).

## APPENDIX A - DEFINITIONS AND ACRONYMS

All definitions listed below are for use in the context of this permit only.

303(d): Section 303(d) of the federal Clean Water Ac t requires states to develop a list of polluted water bodies every two years. For each of those water bodies, the law requires states to develop Total Maximum Daily Lo ads (TMDLs). A TMDL is the amount of pollutant loading that can occur in a gi ven water body (river, marine water, wetland, stream, or lake) and still meet water quality standards.

Adjuvant : An additive that enhances the effectiv eness of the primary chemical (such as a surfactant).

Allowed : Permitted in compliance with the term s and conditions of this permit.

Applicant : the licensed pesticide applicator and a ny other entity choosing to get coverage.

Application schedule: The proposed treatment date(s) for a specific water body during

one treatment season.

Constructed water body : A human-made water body in an area that is not part of a previously existing watercourse, such as ponds, streams, wetlands, etc.

Eradication : Eradication is the permanent remova l of all non-native, invasive aquatic plants of one or more species within a water body or along a shoreline.

Detention and retention ponds : Ponds that are specifically designed and used for the purpose of retaining (i.e. holdi ng) or detaining (i.e. slowi ng down) stormwater or waste

water runoff for the better control of runoff to surface waters of the state.

Direct application : This refers to the purposeful app lication of a pesticide into or onto surface waters of the state. Examples of this would include control of Eurasian watermilfoil, a plant that is treated through subsurface injec tion, or control of Fragrant white water lilies, a plant that grows directly on the surface of the water.

Herbicide : Any substance or mixture of substances intended to pr event, destroy, repel, or mitigate any weed or other higher plant. RCW 17.21.020.

Indirect application : The application of he rbicides in a setting where there may be overspray onto adjacent water bodies. An example of this would be the control of Japanese knotweed along the shoreline of a river – the product is applied to the knotweed, but there may be some inadvertent overspray onto th e river itself.

January 16, 200830

Legally publicly accessible areas : Identified legal passage to any of the public waters of the state, assuring that members of the public have access to and use of the public waters for recreational purposes.

NOI : Notice of Intent (to apply for coverage). Th is is another term used to describe the completed application form.

Noxious weed : A legal term (RCW 17.10) that means a non-native plant that when established is highly destructive, competitiv e, or difficult to control by cultural or chemical practices.

Permittee : Any government entity, private applicat or, or non-governmental organization conducting noxious weed control.

Pesticide : Chapter 15.58.030 (31) "Pesticide" means, but is not limited to:

RCW

17.21.020.

Qualified toxicologist : A person with a Ph.D in toxicol ogy or in a health or ecological science with an emphasis in t oxicology, or a person with a Ma ster’s degree in toxicology

or a related science with an emphasis in toxicology, who is working in the field of toxicology.

Recreational restriction : This restriction should be posted on all public signs and refers to any activities that resu lt in direct water contact (i.e. swimming, water skiing, wading, fly fishing, etc) in the area that has been treated.

Sensitive, threatene d, or endangered plants :

Sensitive: Any taxon that is vulnerable or declining and could become endangered or

Shall : Is required.

Shoreline : The area where water and land meet.

Spray dyes : Colorants that are spraye d onto the targeted weed along with the herbicide. Spray dyes allow better targeting of herbicide sprays since treated and untreated areas are clearly visualized.

Surface waters of the state : Lakes, rivers, ponds, streams, inland waters, salt waters, and

all other surface waters and water courses within the jurisdiction of the state of Washington. Swimming advisory : An advisory required to be posted on all public signs advising people not to swim in the treated area for “x” number of hours after the treatment occurs.

Swimming restriction : A restriction required to be poste d on all public signs stating that no swimming shall take place in the treatment area for “x ” number of hours after a pesticide application occurs.

Treatment area: The area where pesticide is applied and the concentration is adequate to cause the intended effect on aquatic plants or algae.

Upland farm pond : Private farm ponds created from upl and sites that did not incorporate natural water bodies (W AC 173-201A-260(3)(f)).

Wetland : Any area inundated with water sometime during the growing season, and identified as a wetland by a local, state, or federal agency.
