i) The Department recognizes that application of acrolein-based herbicide in the

permittee's district is covered by biolo~c~l opinions(130s)issued by the United

States Fish and WildlifeSeMce~SF;W$),uitder the £ndangered Species Act. These

ii) Compliance with this permit isllotintendedto r~l~yeJ1l,eperrnitteefrom compliance

with other federal and state requ,ire:rnents, su,ch.~FIFMrequirements or Oregon

Department ofAgriculture applicator licensing requirements,

c. Acrolein-based Herbicide Usage In order to reduce the totalamount of acrolein-based

herbicide applied into the irrigation system, the permittee may only apply acrolein-based

herbicide when the .. size of.pcndweed.or othe,r aquatic plants have reached an average length

of 3.to 6 inches.or floating or non-floating masses of algae are visible. The permittee maY

not treat the entire irrigation district at one time,

treatedareas.

4. Required Management Practices to Reduce MOnittiHng

To qualifyfor the reducedmonitoring scheduleallowedin Schedule B.l.b, the permitteemust

manageits gates that dischargeto natural waters in the following manner:

a. Gate Closure The permitteemust:

i)

H)

Close and Lock Close and lock each gate withinthe treatmentarea that discharges

to naturalwaters at least two hours'befbre 'theact()leih~based herbicidewave is

expectedtoreachthafgate.' FOr any latetal c~nal'thatdischargesto natural waters,

eithetthe point of discharge'to natural watersmust be closed and'lockedor the

turnoutto the lateral canal fromthe main canalmust be closed alldlocked.

(1) In makingthis calculation, .the permitteemust considerthe.. volume and velocity

offlow in the treatmentarea and; the diStiiri6e between the poiht acrolein-based

herbicideis applied and the gate to be closed.'The fastestvelocity offlow, as

averaged throughthe verticalwater column, in. arepresentative cross-section of

the channelmust be used. When channelconfigurations vary, calculations may

he made On differentsections ofthe treatlnentarea to determine the time when

the abrolein..based herbicide.wave is'expectedto reach the gate.

(2) These calculations must be documented in the application log;

Tag Gates Attach an easilyvisible tag to water USer deliverypoint that cannotbe

locked. The tag muststate that the deliverypoint has been closed at the request of the

wateruser and may be reopenedonlyby the permittee's personnel.

b. Inspection Requirements Duringthe period whenacrolein..based herbicide levels in the

irrigation systemare likely to be abovethe discharge limitatiOll,thepentlitteemust inspect

wateruser delivery points that cannotbe lockedat least once a day that havebeen closedas

requested by the water user. '

Page 5 of 18

c. Reopening of Gates The permittee may only reopen gates when acrolein-based herbicide is

no longer present at Jevelsabove its discharge ,limitation;. This determination may be made

using on ofthe following:

i) The permittee waits for expiration ofthe holding period as specified in the EPAapproved FIFRA label for the acrolein-based herbicide; or

ii)The permitteecalculates the rate at which the. volume ofwater. in tbe'. treatment area is

replaced by fresh, untreated water based on the portion ofthe treatment area where

such turnover is the slowest (the slowc;~t veloci~ offlow, asaveraged through the

vertical water column, in a representative cross-section oftlie channel must be used).

The permittee may not open the gato{s) untilthe water in fuetreatme,nt area has

turned over at least one time.

(1) The permittee may calculate turnover rates for individual laterals that are fed

from the main canal and open gates in ~se latera)s,if ~e volume ofwater in

the lateral has turned over at leastOl)e time...Fore,xample,a lateralcloser to the

acrolein-based herbicide application point may turnover more quickly than the

main canal or a lateral located fartheJ\~'V~Yfi;ODl the app1ic;a~iOD,point.

... (2) In making this ca.1culati6tl,the permittee must consider the.di,Uu}cebetween

the point acrolein-based herbicide is applied and the gate farthest from the

applicationpoint 19. bereop~d. Whenchannclc01'lfiguratiops vary,

calcul~~9nS maYRe made.9U diffet'~t sections ofthe treatment area to

determine turnover time for the treatment area.

(3) The permittee must also use the field te,st1cit for acrolein-based herbicide to

determine when to begin the turnover period. The,turnover period may not

begin until acrolein-based herbicide is no longer detected at the gate to be

reopened farthest from the application point.
